Elon Musk Says He’s Putting Last Remaining House on the Market – Bloomberg
Posted: June 15, 2021 at 7:28 pm
Tesla Inc.s Elon Musk tweeted that hes decided to sell the last of the homes he owns a week after a report said he and other billionaires paid little or no income taxes for several years.
The electric-car makers chief executive officer tweeted earlier this month that he only has one house in the San Francisco Bay area that is rented out for events, and that if he sold, it would see less use, unless bought by a big family, which might happen some day.
Musk, 49, first announced plans more than a year ago to sell his homes and most of his possessions as a way to blunt criticism of his wealth. Within days, he put two of his California properties on the market.
Last week, ProPublica reported that Musk, Amazon.com Inc. CEO Jeff Bezos and Berkshire Hathaway Inc. Chairman Warren Buffett have paid little income tax relative to their outsize wealth, citing a trove of Internal Revenue Service data on tax returns for thousands of the wealthiest Americans. Musk paid no federal income taxes in 2018 and less than $70,000 in 2015 and 2017, according to the report.
An IRS official said last week that the disclosure of the data for billionaires including Bloomberg LP founder Michael Bloomberg, the founder and majority owner of Bloomberg LP, the parent company of Bloomberg News, has been referred to Federal Bureau of Investigation investigators.
Austin Mayor Hopes Elon Musk Can Help with Housing Problems
After the ProPublica report, Musk tweeted that he will keep paying income taxes in California in proportion with his time in the state, which he said will be significant. He moved to Texas last year and said he now rents a roughly $50,000 house in Boca Chica from Space Exploration Technologies Corp., which has a launch site in the area.

To boldly go where no germs will follow: The role of the COSPAR Panel on Planetary Protection – Open Access Government
Posted: June 11, 2021 at 12:07 pm
As our ventures into the final frontier acceleratethis year alone saw three separate missions arriving at Marsand we land on nearby planets, the challenge is to make sure that we do not bring potentially dangerous material home to Earth (backward contamination) or indeed carry anything from Earth that may jeopardise the scientific exploration of these worlds (forward contamination). Planetary protection against biological contamination is an international concern receiving renewed attention due to new findings and the emergence of commercial actors.
Nations with their own space agencies and space exploration missions are responsible for their space activities under the United Nations Outer Space Treaty of 1967, including by governmental and non-governmental actors. The COSPAR Planetary Protection Policy, while not legally binding under international law, is the only internationally agreed planetary protection reference for spacefaring nations in compliance with Article IX of the Outer Space Treaty of 1967.
The Committee on Space Research (COSPAR) is part of the International Science Council, a non-governmental organisation that brings together scientific unions and research councils from around the world. COSPAR was formed at the dawn of the space age to promote international scientific research in space and provide a neutral forum for the discussion of challenges to scientific exploration, unencumbered by geopolitical considerations. One of its core activities is to develop, maintain and promote a Policy on Planetary Protection in the form of implementation guidelines.
The dedicated COSPAR Panel on Planetary Protection (PPP) regularly reviews the latest scientific research to adapt its planetary protection policy. The most recent updates to the Policy were approved in June 2020, and a major one concerning the Moon is coming up. The COSPAR PPP currently has 21 members representing space agencies and experts from the scientific community.
The Panel endeavours, through workshops, meetings and at COSPAR Assemblies, to provide an international forum for the exchange of information on best practices for adhering to the COSPAR planetary protection requirements. Through COSPAR, the Panel informs and interacts with the international community, including holding an active dialogue with the private sector.
COSPARs PPP is concerned with possible biological interchange during exploration of the solar system and aims to ensure that the scientific research involved is not compromised through terrestrial contamination, to safeguard investment in space science and exploration, while also protecting the Earths environment from any potential hazards of returning samples by a mission to a solar system object.
The PPPs primary objective is to develop and promulgate a clearly delineated policy and associated requirements to protect against the harmful effects of such contamination. This policy must be based on the most current, peer-reviewed scientific knowledge, and is intended to enable exploration, not prohibit it. Planetary protection requirements are not cast in stone and evolve over time as new information becomes available (updates to the Policy are published in COSPARs journal Space Research Today.) The Panel does not specify how to adhere to the COSPAR Planetary Protection Policythis is for the engineering judgment of the organisation responsible for the planetary mission.
Space research involves missions driven by private organisations and by national or international space agencies who send a variety of craft into space to enhance our understanding of its origin and evolution. Some will orbit a planetary body and others, such as the lunar, Martian or icy moon such as the future lunar, Martian or icy moon missions, will land on their surfaces. They will then analyse the surface or internal environment, searching for traces of life. COSPAR PPPs main goal is to prevent such missions from carrying terrestrial microorganisms to the target destination (forward contamination) as well as preventing any contamination from extra-terrestrial material returned to Earth for laboratory analysis (backward contamination). Using a categorisation approach, COSPAR PPP determines whether each mission is low risk or high risk. The five Categories of Planetary Protection outline the recommended measures that an agency should apply to each mission.
Missions deemed to be of lowest risk (Category I) are those to a target not of direct interest for research into evolution or the origin of life. These can include flyby, orbiter and lander missions but to destinations where no specific protections are required, e.g., currently the Moon, Venus, gas giants and some satellites. A special categorisation was recently issued by the PPP for an unrestricted Earth return from Mars moon Phobos by the JAXA MMX mission, as studies showed that samples would not pose a threat for our biosphere after careful handling.
Higher categories include bodies that are of interest for scientific research about the origin of life. Category III, IV and V missions include those targeting bodies (such as Mars, Jupiters moon Europa and Saturns moon Enceladus) which could compromise future missions by causing contamination from Earth microorganisms, and also those that are Earth-return and which may carry extra-terrestrial materials.
For such missions, the highest degree of control is applied to ensure that a minimum level of bioburden (the number of bacteria living on an unsterilised surface) is brought along. Planetary protection technologies are constantly being improved for cleaning and sterilising spacecraft and handling soil, rock and atmospheric samples.
The COSPAR Policy on Planetary Protection is vital for safeguarding our exploration of outer space and scientific research without contamination of planetary bodies or risk for the Earths biosphere. The COSPAR PPP works through a variety of hypothetical scenarios to ensure future scientific research is not compromised. These include whether, after advanced exploration and research, any signs of life found by a rover on Mars is Martian rather than terrestrial contamination, and whether potential extra-terrestrial life brought to Earth is sufficiently quarantined before scientific analyses. They aim not to stifle space exploration and research, but rather to ensure it continues unimpeded through adequate protections and information imparted to scientists and stakeholders around the world.

Paradoxically, space exploration teaches us about the Earth. And the things that we learn are arguably priceless because they are crucial to our survival.
The critical point is that other planets show us what the Earth would be like if things were different. So, for instance, we can see what the Earth would be like if it were smaller or larger, hotter or colder, if it had a different atmosphere, and so on.
Venus is Earths twin in terms of its mass. Yet when space probes visited the planet in the 1960s, they discovered

Carnegie Science Center and Astrobotic launching Pittsburgh into the 21st-century Space Race – NEXTpittsburgh
Posted: at 12:07 pm
Pittsburgh is prepared to face a future dominated by the emerging technologies of robotics, artificial intelligence, biotechnology and medicine.
But what if we stood back a little bit and looked up into the night sky?
The dream of space exploration has new momentum now not seen since the so-called Space Race of the 1950s and 1960s. And a new partnership is positioning Pittsburgh to play a major role in that future.
On June 9, the Carnegie Science Center announced a new partnership designed to inspire and build a pipeline of talent for a new space economy in Pittsburgh. It begins with a new exhibition gallery, Our Destiny in Space, and ends with companies like Astrobotic, which was just awarded $200 million to deliver a rover to the moon for NASA, controlled from its headquarters two blocks away from the Science Center.
This initiative will create opportunities for our regions children to one day find their place in the space industry, said Jason Brown, director of the Carnegie Science Center, at the kickoff event. This will give students opportunities to learn alongside professionals that are building it, right now, today, here in Pittsburgh.
The project includes a new 7,000-square-foot gallery at the Science Center. The new permanent exhibit, Our Destiny in Space, moves away from the familiar, introductory science 101 content, noted Brown. After consulting with educators and students from Pittsburgh Public Schools, the Science Center created an immersive exhibition introducing students to questions about our shared humanity, and how they are addressed as we venture ever deeper into space.
Its expected to open in the fall of 2022, with a focus on Mars exploration particularly the path from Earth to the Moon, and then on to Mars.
The big idea for Our Destiny in Space is that the questions well face in the future for humans living on Mars are the same as those we face here on Earth today, said Brown. As we imagine a better future on a different planet, we discover whats needed to make that future on Earth a reality as well.

The goal of this initiative is to make space accessible to all, but especially to marginalized groups and to students underrepresented in STEM, said Brown. The way we want to do this is by first lighting the fires of inspiration, and then clearing the barriers to entry. Inspiration, exploration, access and inclusion.
Space is a growing $425 billion industry. The partners on this project include the Keystone Space Collaborative, the Readiness Institute at Penn State, Discovery Space of Central Pennsylvania, as well as the Moonshot Museum, Carnegie Science Center and Astrobotic.
Astrobotic, as a business, is all about making space accessible to the world. We are so dedicated to that, that we have gone to the next step to create the Moonshot Museum, said John Thornton, CEO of Astrobotic.
The big idea is that kids young and old can walk right up to the glass, see a real spacecraft being built on the other side that will be sent to the surface of the moon and deploy real sensors and robots down to the surface You can get a front-row seat from our mission control, right up the street, added Thornton.
The Moonshot Museum, which will be located within Astrobotics North Side headquarters, was started with help from a $500,000 grant from the R.K. Mellon Foundation. It will be the first museum in the state dedicated to space exploration.
During last nights event, Pennsylvania Congressman Conor Lamb recalled when the first Soviet satellite Sputnik captured the worlds imagination, and showed how far behind America was in space exploration. He said that President Kennedy was determined to reverse that, and promised to land on the Moon, at a time when more Soviet dogs had been in outer space than American astronauts.
He says to his team, Look, coming in second in the Space Race is the same as losing. Theres no second place. We have to change the game, said Lamb. In a literal sense what he declared was impossible. There was no rocket capable of getting us to the Moon, no spacecraft capable of landing in 1961. But he had the instinct that if you actually set the goal and follow it up with enough resources, America was able to meet challenges like that.
As we all know, America rose to meet this impossible challenge.
Ultimately there were 410,000 people working on the Apollo program, many with NASA but in the private sector as well, added Lamb. Companies like Alcoa in western Pennsylvania supplied them with over a million pounds of aluminum. Outside of war, its the largest single endeavor that a group of people have ever really taken a part in, until, really, the pandemic happened.
That kind of resolve, that talent, that perseverance, is still present in Americans.
We, the Americans of the 2010s, 2020s and 2030s, are just as capable of accomplishing something like that today, as they were in the 1960s, said Lamb.
Pittsburgh is poised to be a place where that work happens.
We are creating a true ecosystem, from middle school to high school all the way through college and ultimately in industry, said Thornton. You can live and work in space in Pittsburgh.

The Science Center kickoff event also featured a keynote speech by Thomas Zurbuchen, associate administrator for NASAs Science Mission Directorate, who detailed the recent successes in exploring Mars.
Look at the Moon, Zurbuchen said. Look at it and think of all these places were going to go. And landers from this community will land and do amazing science.

STEM Ed: North Carolina Teachers Win New Tools to Enhance Learning about Space Exploration – The Grey Area News
Posted: at 12:07 pm
Aldrin Family Foundation logoSpace Exploration Bundles Awarded to Four Schools in Hickory, Burke, Pitt, and Union Counties
Four North Carolina teachers will get new tools and technology to help teach about outer space and inspire and empower students in the field of space exploration. The space education bundles are valued at $5,000 each and include a large Mars or Moon learning map, Mimio Mybot educational robotics system, a Lunar or Mars Pro Globe with augmented reality technology, and many other resources.
Educators teaching 5th-8th grade could apply for the competition through the North Carolina Business Committee for Education (NCBCE), a business-led, education nonprofit within the Governors Office. The Moon and Mars Bundles were donated by Public Consulting Group and the Aldrin Family Foundation.
Winning teachers include:
Said Governor Roy Cooper, Teachers can be the spark that inspires students to follow a promising career path like space exploration. Its exciting to see students interested in science and math because we need more young people in our workforce pursuing STEM careers.
A total of 27 educators applied statewide for the competition by writing two paragraphs about what space exploration means to them and what winning these bundles would provide to their counties.
Said Tony McLean Brown of Public Consulting Group, As part of our 35th Anniversary, PCG employees who live, work, and play in North Carolina are proud to support public school teachers and students who are excited about space. Whether they go on to NC State University or get a technical certificate from Duke Energys Apprentice Program, learning about space exploration and colonization is going to prepare these students for the future. It is very exciting.
Added Andy Aldrin, president of Aldrin Family Foundation, We strive to ensure that students never lose their excitement to learn about space. We hope that these deserving schools and their students are reenergized by the hands-on experiences offered by the Mars and Moon Maps and the curriculum that comes with them.
The contest grew out of an online conference sponsored by NCBCE last year to help educators with remote learning. The Aldrin Family Foundation presented at the NC Student Connect Conferences where they provided useful knowledge and tools for NC STEM teachers on how to incorporate space exploration into their classes to increase interactivity and interest. The session left teachers across North Carolina excited and interested in finding more ways to engage their students in learning about space. The Aldrin Family Foundation, along with Public Consulting Group, decided to award four of the large bundles to North Carolina STEM teachers.
Space-related careers include astronauts, engineers, space suit designers, satellite technicians, communications experts and other STEM (science technology engineering and math) jobs.
I didnt realize the many pathways which existed for a career in a space-related field. I would love the chance to share with my own students that there are a multitude of career paths related to this fascinating field, and that they really do have the potential to pursue a space-related career, winning teacher Vanessa Lail (Hickory Public Schools) wrote in her application.

The final frontier for investors: space exploration ETFs and trusts – Interactive Investor
Posted: at 12:07 pm
A space exploration investment trust is proposing to IPO, hot on the heels of the YODA ETF.
Space exploration has emerged as a potential investment theme. This has already been picked up by fund houses in the US, most notably with the creation of the ARK Space Exploration and Innovation ETF.
Now, investors in the UK also have a way to gain pure-play access to this theme.
This morning (11 June), Seraphim Space announced it intends to launch a space-themed investment trust, called Seraphim Space Investment Trust. The trust will list on the London Stock Exchange and hopes to raise 100 million at IPO. Will Whitehorn, former president of Virgin Galactic (NYSE:SPCE), will sit on the trusts board.
According to the announcement, the trust will invest in a diversified international portfolio of early and growth stage space tech businesses.
The trust will initially acquire a portfolio of 19 seed assets, already owned by the Seraphim Space Fund. The company highlights several of the firms in question, which are currently privately owned and valued at over $1 billion (707million): Arqit, a quantum encryption company;Spire Global, a weather forecaster;and AST & Science, the space-based 4G mobile broadband network provider.
With many leading space-related companies still in their infancy and therefore not yet listed, the trust is likely to have exposure to many unlisted companies. The closed-ended nature of investment trusts make them an ideal vehicle for giving investors accessing to companies not yet listed on a stock exchange.
The trust defines the sort of companies it will hold as those which rely on space-based connectivity or precision, navigation and timing signals or whose technology or services are already addressing, originally derived from, or of potential benefit to the space sector.
Rather ambitiously, the trust says it is targeting an annualised net asset value total return of at least 20% over the long term.
However, for those who prefer ETFs, the recently launched Procure Space ETF USD (LSE:YODA) is a potential option. The ETF listed on the LSE in early June, making it Europes first space thematic ETF. For an ongoing charge of 0.75%, the ETF tracks the S-Network Space index.
At least 80% of the ETFs portfolio is allocated to companies earning most of their revenues from space-related business. The Space Index splits these into two main groupings: satellite operators and hardware. Satellite operators are companies that either own or manage satellites or subsystems aboard satellites. Hardware refers to companies involved in the sale of equipment used by manufacturers in the creation of satellites and launch vehicles, as well as spacecraft components and supporting ground equipment.
However, the ETFs issuers envision the ETF gaining more exposure to other emerging areas of the space economy, such as space resource extraction and space tourism. The ETF currently has a holding in Virgin Galactic, already giving it exposure to the latter. As it stands, the ETF will hold 30 stocks.
Historically, if an investor wanted to gain exposure to space stocks, one seemingly obvious option would the aerospace and defence sector, notably companies such as Boeing. However, such companies are only loosely related to space flight and exploration, making them a far from perfect way to gain access to the theme.
More recently, there has been a focus on the potential of space tourism, the prime example being Virgin Galactic, which went public in 2019. However, space tourism is just one small part of the growing commercial potential of space.
Advances in technology are overturning traditional models for operating in space, with low-cost access to space becoming a reality, most notably thanks to innovations around reusable rockets. Since 2010, the cost of both building and launching satellites has fallen by a factor of more than 100x.
These lower costs have the potential to open up all sorts of commercial applications, particularly in areas such as telecoms and satellites. Space-based communications technology are also becoming more integral to the economy. A good example of this are location-enabled apps, such as Deliveroo and Uber, which make use of GPS.
New communication technologies such as 5G, cloud computing, and machine learning also require ever bigger transfers of data. The use of these technologies, therefore, will be increasingly reliant on satellite infrastructure.
As a result, in the years ahead, we should see a surge in satellites in orbit. Today, approximately 4,000 satellites are circling the globe. By some estimates, that will increase by 100,000 over the next decade.
The increased commercialisation of the space economy can already be seen in the make-up of investment and spending. According to statistics from the Space Foundation, in the 1960s, government spending represented almost all space spending. Today, that has fallen to just 20%, with the other 80% coming from commercial spending on infrastructure, and their support industries, alongside commercial space products and services.
According to the mostrecent Space Report from the Space Foundation, the space-related companies generated over $400 billion in revenues in 2019. However, according to the Bank of America, that should grow to $2.7 trillion by 2045.

Everything you need to know about Chinas space race – The Week UK
Posted: at 12:07 pm
Space exploration has been a long-term goal for the Peoples Republic ever since the Soviet Union launched Sputnik 1 in 1957. Chairman Mao lamented at the time that we cannot even put a potato into space, andthe Communist Party leadership vowed to produce two bombs and a satellite: an atomic bomb, a hydrogen bomb, and a satellite.
China did not launch its first satellite until 1970, but since the 1980s it has been catching up fast with the major spacefaring nations. Its space programme really announced itself to the world in 2003, when Yang Liwei became its first taikonaut (as China calls its astronauts), orbiting the Earth 14 times during a 21-hour flight aboard the Shenzhou 5 spacecraft. China thus became the third nation to independently send astronauts into space.
Under President Xi Jinping, plans for Chinas space dream, as he calls it, have gone into overdrive. It aims not only to pass the milestones achieved by other nations, notably the US, but to overtake them as the leading space power by 2045.
The China National Space Administration had an annual budget of about $8.9bn last year, second only to Nasas (of around $23bn). It has landed rovers on the Moon and, more recently, on Mars (see box). Last year, it completed the BeiDou satellite constellation, a rival to the US Global Positioning System. This year, it launched the first part of a permanent space station into orbit (debris from a Long March-5b launch rocket fell back into Earths atmosphere on an undirected dive, crashing into the Indian Ocean).
The first mission in Chinas lunar exploration programme, Change 1, reached the Moons orbit in 2007. Six years later, it landed a robotic rover on the lunar surface, which operated for 31 months. Other nations had achieved such feats before, but China has pioneered too: in 2019, Change 4 became the first spacecraft to land on the far side of the Moon which faces away from the Earth, making it difficult to communicate with space-craft there.
At the end of 2020, the fifth Change mission scooped up a few kilograms of rock and brought them back to Earth the first lunar sample-return mission since the final Soviet Moon mission in 1976. Three more lunar missions are planned by 2027, to prepare the ground for a future Chinese base (potentially built in collaboration with the Russian space agency, Roscosmos) that would be permanently inhabited by taikonauts.
In late April, China launched Tianhe, the first module of what will become a new space station, Tiangong (Heavenly Palace). Two further modules will be added to Tianhe next year, which will provide laboratory space for research on everything from the long-term impacts of living in microgravity to studying how fluids and materials behave beyond Earth.
Alongside its space station, China also wants to launch a space telescope, similar in size to Nasas Hubble telescope. When complete, Tiangong will be able to accommodate three taikonauts for long-term missions or six for shorter trips. Astronauts from other countries would also be allowed to visit the space station; Tiangong will become operational by 2023, just as the International Space Station comes to the end of its operational life.
China is determined to be the worlds science and technology superpower. A space programme is a tried-and-tested way for a nation to enhance its industrial and economic strength, and also project prestige and technical competence to its own citizens and to the rest of the world. China sees its space capability as important for economic and diplomatic leverage: it is trying, for instance, to persuade countries to dump the USs GPS satellite navigation in favour of its BeiDou system.
From Chinas perspective, it has little choice but to build its own ambitious space programme: concerns about technology theft mean its scientists have been banned by the US Congress since 2011 from working with Nasa, and shut out from projects such as the International Space Station. And in todays networked world, space technology is critical not just to the financial system, for example, but to national security.
Space is already an arena of great power competition, Lloyd J. Austin III, the new US secretary of defence, declared recently. Satellite networks are used to keep military information systems running; both the US and China have the capacity to knock out enemy satellites in the event of a conflict. The situation is made more complex because most space technologies are dual-use: they can be used to perform civilian or military tasks.
Understanding Chinas aims is made difficult by the countrys opaque policy-making apparatus, and by President Xis military-civil fusion development strategy, which purposely blurs the lines between military and civilian technology development on everything from semiconductors and 5G to aerospace and AI.
China wants to send a second lander to Mars by 2028 and, eventually, to bring samples back from the red planet. That next phase of Mars exploration could become a genuine race with Nasa and the European Space Agency, which are working together on an ambitious sample-return mission of their own. Future missions could also include a sample-return mission from an asteroid, a fly-by of a comet, and orbiting observatories for Venus and Jupiter.
China is continuing to develop new spacecraft too. There are rumours that it is working on a reusable space plane. And Chinas space administration reportedly wants to beat Nasa in the race to take astronauts to Mars.
In a matter of months, Chinas Mars mission, Tianwen (meaning Heavenly Questions), has completed a stunning trio of achievements: it entered orbit in February, landed on the surface of the red planet (at Utopia Planitia) on 14 May and, a few days later, sent its Zhurong rover (named after a Chinese god of fire) trundling onto the rocky ground.
Getting to Mars is hard, but landing is much harder: Nasa calls the descent through its super-thin atmosphere the seven minutes of terror. The Soviet Union landed a craft on Mars in 1971, but it stopped communicating shortly after it reached the surface. Only the US had previously managed successful Mars landings the most recent being the Perseverance rover in February.
Zhurong weighs in at around 240kg, a quarter of the mass of Nasas Perseverance, but similar to the Spirit and Opportunity rovers that landed on Mars in 2004. Like those older Nasa rovers, Zhurong is powered by solar panels (Perseverance uses nuclear-powered batteries). Its instruments, including cameras, ground-penetrating radar and a magnetic field detector, will study the planets surface, topography, atmosphere and geology, and in particular the distribution of ice which could be a useful resource for human visitors.

Engineering Extremes: Keeping Earth’s orbit safe by clearing up space junk – Professional Engineering
Posted: at 12:07 pm
Astroscale's ELSA-d mission will demonstrate the technology required for commercial space debris removal
As head of space situational awareness, Toby Harris job at Astroscale UK involves analysing computational models of the orbital environment and quantifying risk to help his company select missions and develop spacecraft.
When his five-year-old son asks, hes got a simpler answer ready: Im the rubbish man in space.
Its a humble way to describe a colossal mission: to keep Earths low orbit clean and safe for a new age of space exploration.
With new technology, plummeting costs and fresh players (such as China and India), space is exciting again. Companies such as SpaceX, Blue Origin and Virgin Galactic are building a new commercial industry that, by some estimates, will be worth nearly $1 trillion by 2030. From tourism to communication, from mineral exploitation to Mars missions, space is going to get busier. And demand for rubbish man missions to grab and bring down debris is expected to grow.
Toby (40) didnt study engineering but has so far spent his career engineering solutions to the kind of problems they make Hollywood films about.
For more than a decade, he supported the UK governments nuclear defence strategy. Then came the UK Space Agency, where he and a team of engineers inspected and licensed spacecraft. Leading delegations to the United Nations, hes often been the link between engineers solving technical problems and politicians negotiating policy.
Now at a company where seven out of every 10 employees are engineers, Toby, a father of two, spends his days thinking about how to clean up old space junk and prevent new junk from appearing. He also figures out how to bring better governance to a place that everyone wants to use, but no one is really responsible for. A place where a pea-sized object flying at more than 25,000mph can destroy a satellite. Where hunks the size of double-decker buses have been hurtling through the silence for decades.
People want to use space, says Toby. But theres more and more risk.
There are more than 3,000 active satellites orbiting Earth today. Thousands more are defunct. Nasa tracks half a million pieces of debris. Big collisions are, thankfully, rare, but one such crash in 2009 created thousands of pieces of junk, each a bullet threatening other objects. Satellites on opposite sides of the Earth can be on top of each other in under an hour. Its an extreme environment, becoming more extreme with every launch. And, with the arrival of large constellations of satellites, these launches are more frequent than ever.
For Toby and companies like Astroscale the focus is on prevention and removal.
Preventing space junk involves complex liability laws and better control over spacecraft, being able to manoeuvre them, predict the movement of other objects, communicate with other operators, and get out of the way if need be.
Removal is just as tough. Dead satellites tumble violently at ridiculous speeds. Top stages of rockets weigh tonnes. Getting close to these objects requires aligning a new spacecraft with their orbits, while avoiding all the space junk already up there. Not to mention actually catching them and pulling them down into the atmosphere, where they can burn up or land safely.
You have to juggle a whole bunch of operations at the same time, Toby explains.
But difficult problems offer exciting challenges to mechanical engineers. These engineers test the weight of spacecraft against the power of their thrusters, design solar panels to withstand projectiles, figure out the best ways to grab pieces of debris or broken satellites, and solve endless other puzzles.
Its how we get the job done, explains Toby, whos had a hand in all kinds of engineering work, from aeronautical to software. He believes mechanical engineering is a fundamental part of space exploration.
Apart from understanding the space environment, part of Tobys juggling act involves thinking about space sustainability and preparing demonstrations, like Astroscales ELSA-d mission, which launched in March. The mission is aimed at demonstrating technologies needed for docking with space debris and removing it. With an outdated treaty from the 1960s, the rules of space are, at best, murky, and countries are not responsible for cleaning up. So, just like with carbon emissions, Toby and others in his field are trying to get ahead of the problem. To get decision makers to realise that space pollution could make entire orbital highways too dangerous for use and that no single country can solve the problem alone.
To escape these kinds of deep questions and things like the Kessler effect the cascading of space collisions Toby paints the cosmos or reads sci-fi books by Stephen Baxter, one of his favourite authors. He runs and plays golf. And he spends time with his two kids, who may one day thank the rubbish man of space for his efforts.

Mapping Gene Activity In Tissues Just Got Easier And Why It Matters For Space Travel – Forbes
Posted: at 12:07 pm
A section of prostate cancer tissue overlaid with data from the Visium Spatial Gene Expression for ... [+] FFPE with each cluster representing a different gene expression profile.
Understanding the relationship between cells and their locations inside tissues is an important part of learning more about biology and potentially curing multiple diseases, such as cancer. Spatialomics is the research method that allows scientists to measure gene activity from the cells inside tissues and to map where the activity is happening.
Named the method of the year by Nature in 2020, spatialomics, also called spatially resolved transcriptomics or spatial transcriptomics, is transforming research in many areas, like cancer, neurology, and immunology. Now, 10x Genomics, a life science technology company, has announced a new way to study spatialomics in preserved tissue samples.
10x has an advanced platform for spatial transcriptomics called Visium Spatial Gene Expression that visually maps gene expression in a tissue sample. It helps researchers study the relationship between cells and their organization within tissues.
Understanding this relationship is critical for understanding both normal development and disease pathology. Visium measures total mRNAthe message-carrying instruction molecules for DNAin intact tissue sections and maps where gene activity is happening.
Although Visium is already being used by many researchers, 10x discovered an opportunity to make it even more useful for scientists. In general, tissue samples that come from a biopsy are immediately placed in formalin (formaldehyde) or another solution to preserve them. However, studying gene activity in preserved tissues is difficult, so 10x found a way to change this.
"One of the first things that happens to tissues is putting them in a fixative," says Ben Hindson, co-founder and CSO of 10x. "The previous limitation was that a lot of the tissues being used by researchers were preserved or frozen, so you get these formalin-fixed and paraffin-embedded blocks. This destroys most of the RNA, which is the good stuff you are trying to look for in the sample."
Ben Hindson, Chief Scientific Officer and Director of 10x Genomics
Now, 10x has released Visium Spatial Gene Expression for FFPE (formalin-fixed and paraffin-embedded) assay. The platform can now handle spatial analyses in preserved tissue samples. Researchers can easily add the "where" to the "what" in their genomics research and map out where gene activity is happening in a tissue specimen, whether it is frozen or preserved.
"Visium Spatial Gene Expression for FFPE is one of the products that our customers have been asking for because it opens up new research opportunities that they could not do before," says Shernaz Daver, Global Communications Head at 10x.
The fragments created by formalin-fixed and paraffin-embedded tissue blocks used to be difficult to analyze and not compatible with most molecular biology techniques. They would not produce useful results for researchers trying to study them using common approaches.
Visium for FFPE has many potential applications, such as studying samples from biobanks with preserved tissues or from imperfect samples taken from patients during surgery. The platform creates the opportunity to study cellular states from more samples that are linked to treatment response and outcomes.
But spatialomics is not only making waves in research on Earth. Now scientists are wondering if they can use the technology to study how the extreme environment of outer space affects living organisms.
As we continue to learn more about biology, new opportunities to study it in different ways are becoming possible. When bioengineering and space exploration combine, the ability to test new ideas in a microgravity environment becomes possible.
10x is collaborating with Axiom Space on a new mission to the International Space Station (ISS). The mission will include life science research in orbit, specifically using single-cell genomics technology developed by 10x.
"One of our early investors, John Shoffner, who is going on the mission with astronaut Peggy Whitson, helped us connect with Axiom," says Hindson. "Biology changes in space quite significantly, so this research is important."
Studying single-cell technologies in a microgravity environment could help life science companies advance their research. Gene expression in microgravity could teach us more about human diseases and conditions both for future space missions and back here on Earth.
Thank you to Lana Bandoim for additional research and reporting in this article. Im the founder of SynBioBeta, and some of the companies that I write about are sponsors of the SynBioBeta conference and weekly digest.
After a year of digital meetings, were bringing synthetic biologys leading community of ... [+] innovators, investors, engineers, entrepreneurs, scientists, thought leaders, policy makers and academics together to Build Back Better With Biology!

Could Russia threat to leave ISS launch another space race? – Deseret News
Posted: at 12:07 pm
Russian officials threatened to pull out of the International Space Station project, Reuters reported on Monday.
The International Space Station launched in 1998 as a collaborative project for outer space research. The orbiting lab has two segments: one operated by Russia and one operated by the U.S., Canada, Japan and the European Space Agency, Reuters said.
The sanctions Russia wants to be lifted were implemented in December from former U.S. President Donald Trump, reported CNBC. Trump designated Russias JSC Rocket and Space Center Progress and JSC Central Research Institute of Machine Building as having connections with the Russian military.
We have spacecraft that are nearly assembled but they lack one specific microchip set that we have no way of purchasing because of the sanctions, Rogozin explained via Reuters.
Either we work together, in which case the sanctions are lifted immediately, or we will not work together and we will deploy our own station, Rogozin said per CNBC.
The U.S. plans to continue the ISS program through 2030, says CNN. If it follows through on threats to leave, Russia could withdraw from the ISS program as soon as 2024.
If Russia starts just depending on China, then, I expect we would have a whole new race to the moon with China and Russia against the U.S., Nelson, chief NASA director, said to CNN.
Maintaining a strong relationship with Russia in space exploration will be key to keeping space a neutral territory, according to a CNN report.
