BB-8 Flies? Adorable Japanese Drone Ball Tours Space Station – Space.com

Posted: at 3:48 am

Space watchers have seen footballs, mini-soccer balls and water balls float through the International Space Station but never a drone ball. Now, new footage of a spherical Japanese robot shows it hovering and skittering around the Destiny laboratory.

The hope is that the robot will not only save the crewmembers time today, but could also improve robotic-human cooperation in future space expeditions, according to a statement from the Japanese Aerospace Exploration Agency (JAXA).

"Int-Ball," as the drone is called, would add to a growing legacy of robot "helpers" in space, including NASA's Robonaut 2 (which can throw switches and may eventually do simple spacewalk tasks) and the adorable, talking Japanese Kirobo, which made small talk with astronaut Koichi Wakata in 2013.

The Japan Aerospace Exploration Agency's JEM Internal Ball Camera, called Int-Ball, can record video in space while remote controlled from the ground.

Videos show Int-Ball, under the watchful eye of NASA astronaut Peggy Whitson, moving near the walls, taking pictures of experiments and other regions in its vicinity. One shot shows a laptop lazily floating by. In another clip, Peggy Whitson's fellow NASA astronaut Jack Fischer playfully hides behind a camera, taking pictures of the drone.

If the drone works out as planned, it could reduce or eliminate the time astronauts spend taking pictures, an activity that takes up about 10 percent of their working hours right now, JAXA officials said in the statement.

NASA astronauts Peggy Whitson and Jack Fischer work on the International Space Station as Int-Ball observes, above.

It also would let teams on the ground, where Int-Ball is controlled, look at the crew's work from the drone's viewpoint, JAXA added. "The effective cooperative work between in-space and on-the-ground [teams] will contribute to maximized results of 'Kibo' utilization experiments," the agency said, referring to the Japanese experiment module on the space station.

Int-Ball launched aboard SpaceX's Dragon spacecraft on the CRS-11 resupply mission June 3 and arrived at the space station June 5. It's now in testing to ensure that its images and video are recording information as planned, under control from the JAXA Tsukuba Space Center.

JAXA added that Int-Ball's camera which appears to be located between two "eyes" on the robot uses technology that has already been tested on past drones. The ball's exterior and interior were fully 3D-printed on the ground.

See Europe from Above in Breathtaking Ultra-HD Video from Space – Space.com

Posted: at 3:48 am

Now anyone can see Europe from an astronaut's point of view with this epic video shot from the International Space Station.

Captured with a 4K ultra-high-definition camera, the video shows a crystal-clear view of Europe, starting with Spain and flying east all the way to Budapest, Hungary. In the time it took to shoot this video clip a little over 3 minutes the space station traveled nearly 1,000 miles (1,600 kilometers). [Earth from Space: Amazing Astronaut Photos]

The space station orbits about 250 miles (400 km) above Earth, and it captures the view down below with several onboard cameras. Traveling at about 17,500 mph (28,000 km/h) relative to the ground, it whizzes around the globe every 92 minutes. But the view is not the same every 92 minutes, because the space station's flight pathshifts slightly with each orbit.

Astronauts aboard the International Space Station capture views of Zadar, Croatia; Vienna; Munich; and Salzburg, Austria.

The footage was recorded in August 2016, and NASA's Johnson Space Center, which oversees activities on the space station, released the video Monday (July 17). The groovy background music was produced by Swedish composer Joakim Karud.

Cute zero-gravity robot is newest member of the International Space Station crew – Mirror.co.uk

Posted: at 3:48 am

An adorable little robotic camera drone with wide illuminated eyes and a perpetually surprised expression has joined the crew of the International Space Station.

Known as Int-Ball, the bot can be controlled remotely by researchers on the ground, allowing them to capture images and video from aboard the artificial satellite.

Int-Ball contains actuators, rotational and acceleration sensors and electromagnetic brakes, which allow it to move around autonomously in zero gravity.

Developed by the Japan Aerospace Exploration Agency (JAXA), it was delivered to the ISS on 4 June 2017, and has already started feeding photos and video back to Earth.

JAXA claims that Int-Ball could eventually replace the need for astronauts to capture photos and record video aboard the ISS - tasks that currently take up about 10% of their time.

It could also enable more cooperative work between astronauts and researchers, as those on the ground would be able to see things from the same perspective as the crew.

During its time on the ISS, JAXA will be take part in experiments both inside and outside the space station, in order to test and improve its performance.

JAXA hopes that it will also help to promote the use of robotics technology in future space exploration missions.

Plan for a mostly water ice space station 90 times bigger than the ISS – Next Big Future

Posted: at 3:48 am

An analysis by John Bucknell (x-Spacex senior engineer) describes an 11 meter diameter robotic vehicle with a 6,000-megawatt nuclear thermal rocket in a NTTR arrangement. The rocket would be single stage to orbit and would be immediately be able to refly after landing and refueling much like todays airliners. Even fully reusable Spacex rockets where all stages are resused would need to be re-assembled.

He describes SSTOH missions to place a 21 meter minor and 214 meter major diameter toroidal habitat in space, capable of full terrestrial gravity simulation by spinning at 3 rpm. The habitat begins as two thin films defining the interior and exterior surfaces of the torus, which is then inflated with lunar-sourced water in a 1m thick shell and allowed to freeze.

Access to space is driven by the economics of launch vehicles. A previously published rocket propulsion cycle called the Nuclear Thermal Turbo Rocket (NTTR) is able to achieve payload fractions of more than 45% to Low Earth Orbit (LEO). This rocket is intended to be completely reusable for the launch mission as it is a Single Stage to Orbit (SSTO) vehicle, which improves economics vastly. However, providing material to LEO is not always the most economical solution for permanent space-based habitation. In-situ resource utilization (ISRU) has been proposed as a method for avoiding the Earths gravity well for space-based construction with solutions proposed using Lunar, Martian as well as other resources.

The Air enhanced nuclear thermal rocket has been described a few at times at Nextbigfuture.

The proposed space station would be close to the size of Titanic but the space station would consist of mostly water ice

Water ice can be used as both reaction mass for propellant in liquid form and as structure in solid form. Nuclear Thermal rockets in particular are well-suited to in-space propulsion as they can add enthalpy to a variety of propellants for thrust without requiring processing plants to achieve chemically active reactants, thus saving on mission payload mass. A mission is proposed that leverages the NTTR vehicle as well as ISRU to construct an orbital habitat of Lunar water ice with a single terrestrial launch (Single Stage to Orbital Habitat SSTOH).

The lunar water ice is extracted from permanently shadowed regolith on the Lunar south pole, where the NTTR vehicle propulsively lands and places 54 tons of payload. The lunar payload is comprised of a small 30 MWth nuclear reactor and associated mechanisms able to extract sub-surface ice.

NOTE NASA will soon officially confirm that there is surface water ice at the lunar pole. The Lunar Reconnaissance Orbiter did find evidence of frost on the moon earlier in the year, but there is a NASA paper that will be released soon that will confirm surface water ice.

The NTTR vehicle fills its propellant tank with 720 tons of lunar water, and using the water as a propellant delivers 400 tons of water to the habitat in LLO before returning to the Lunar water extraction plant. The reusable NTTR vehicle makes 100 trips to inflate the 40,000-ton habitat, with approximately one trip per 24 hours. Subsequently, the lunar water extraction reactor can be transported to the habitat as a power supply and the NTTR vehicle can push the habitat to a Lagrange point.

The 40,000 ton habitat would be just short of the max cargo of a Panamax container ship. The ISS weighs 450 tons.

In such a fashion, a single vehicle of low investment can produce a 199,000m^3 habitat within 5 months of launch.

In 2015, Bucknell presented the Nuclear Thermal Turbo rocket which added air-breathing to a nuclear thermal rocket. Bucknell design would have 1664 ISP. 60% more than the best prior nuclear thermal rocket designs.

Buzz Aldrin: It’s Time for Humans to Start Looking at Other Planets to Live On – Futurism

Posted: at 3:48 am

Chasing the Unknown

Buzz Aldrin is an acclaimed astronaut, engineer, and (of course) the second human being to ever walk on the Moon. Over the years, he has inspired entire generations to look beyond the bounds of Earth and pursue the unknown. As Aldrin previously noted, human beings are meant to be inquisitive. Were meant to be achievers. And to this end, Aldrin has dedicated his life to advancing humanity through discovery, creating explorers and scientists alike in the process.

Most recently, Aldrin helped to create a virtual reality (VR) experience that allows people to travel to Mars. As one of the few individuals who has ever had the privilege of stepping onto an astronomical body besides Earth, Aldrin is able to expertly assist in conveying the experience of space travel to the everyday individual and, in so doing, take people (virtually) farther than they have ever gone before.

In a recent interview with Futurism,Aldrin weighed in on just how important it is for us, as humans, to take this next step in journeying into the final frontier, One of the things that makes space exploration so exciting is that the possibilities are endless. Mars is the next actionable step for us we have never been closer to knowing and exploring another planet. Plus, I believe that Mars has realistic potential for colonization.

Aldrin continued by noting that, in order to make humanitys future on Mars a reality, we will need to start garnering interest and making plans for tomorrow today: Now is the time to start thinking seriously about what life on Mars might look like in the future. I believe we can have the first Human Martians at Mars by 2040.

Obviously, a virtual journey to Mars isnt exactly the same as a real Martian excursion; however, such technologies can, in some small way, help bring people to the stars who otherwise might not ever have the opportunity. In this respect, the VR experience is truly valuable. As Aldrinnotes, We have a long way to go before trips to space are widely affordable for everyone. Luckily AR/VR technology is here now.

Aldrin continued by asserting that, more than just showing people what the voyage to Mars will be like,this type of experience is an integral part of encouragingpeople to get excited about science and exploration. And in todays society, where denialism and sensationalism dominate many conversations, a genuine interest in science is more crucial than ever. Aldrin believes that exploring the vast recesses of space can help in this regard because, as he asserts, space travel is a great unifierit captures our collective imagination, encourages our curiosity, and inspires our creativity.

To this end, Aldrin thinks that it is through these small pushes in the right direction that humans will finally make it to other worlds. Because we are, at the end of the day, wanderers: It is in our nature to explore. We, as a species, are curious and want to see whats over the next hill, see how fast we can go. It was only 66 years from the point that the Wright brothers flew to us flying rockets to the Moon.

If this VR voyage sounds like something that would interest you,Aldrinand Terry Virts,the former commander of the ISS, are teaming up withOmaze, a donation-based experience platform, to offer one winner (and a friend) a chance to celebrate the Apollo 11 anniversary as VIPs at the ShareSpace gala. You will get to hang out with the pair and experience Aldrins virtual Mars experience. Best of all, this effort supports The ShareSpace Foundation, which is a nonprofit dedicated togetting kids involved with STEM.

In the words of the Carl Sagan,Human beings are a curious, inquisitive, exploratory species. I think that has been the secret of our success as a species. Aldrin embodies this exploratory quest and, through AR and VR, he wants to spark that curiosity and need to explore in all.

Of course, no one is positive when the first human footsteps will leave their mark on the Martian surface, but the quest to get us there is how we will continue to advance as a species.and it isnt just astronauts and rocket scientists who can (and should) participate in this great journey. Whether virtually or through other means of education and involvement,it is now possible for us all to engage our minds, hearts, and exploratory imaginations. Its a race we must run together.

Starship Congress presentations make the case for permanent moon colonization – Next Big Future

Damien Turchi is a graduate of Drexel University in Mechanical and Aerospace Engineering, founder and former president of the Icarus Interstellar Drexel University Student Chapter and lead coordinator of the first Interstellar Hackathon at Starship Congress 2015 at Drexel University, PA. He is currently a director of Icarus Interstellar.

On the Development of a Permanent Lunar Settlement: A Micro-Literature Review and Suggested Action

Since the 1960s, humanity seriously discusses the idea of a permanent lunar settlement. In both academic and professional literature, many designs for an initial settlement are proposed to varying fidelity. NASA published a comprehensive review of the most promising designs in the 1990s. Recent literature is not as detailed in its scope.

This study analyzes the designs NASA considered to be of significance in the 90s and discusses the benefits and cons of each. In addition, several recent works are assessed. From this review, the author concludes that an initial lunar settlement is possible through further development of existing design work, but that a superior option is neither immediate nor obvious.

Selecting a single framework (or a specific hybrid of several) is critical to best funnel capital into the most promising technologies. An action path is proposed that leverages consideration of permanence and significance as feedback to clearly characterize the best design choice for initial funding. Permanence seeks to answer, How can we ensure that the construction of the first lunar base is able to expand into the foreseeable future in both population and space?, while significance seeks to answer, How can we ensure that the consequences of operating the settlement are economically beneficial to society? There is not much literature to answer these questions, despite the importance of the answers.

The solutions will no doubt be a culturally diverse response, considering the needs of society as a whole to serve as a safeguard for the temporal success of a permanent lunar settlement.

2. Haym Benaroya is a Professor of Mechanical and Aerospace Engineering at Rutgers University. His research interests are focused on the conceptualization and analysis of structures placed in challenging environments. These include offshore drilling structures and lunar surface structures for manned habitation. Often, the characterization of the environment is the primary challenge, as with problems of flow-induced vibration.

The Moon as the Site for Humanitys Expansion into the Solar System and Beyond

The Moon offers numerous advantages, providing a foothold for humanity as it struggles to escape Earths gravity well to become a spacefaring civilization. While the battle for most has been between the Moon and Mars, the vision of the Starship Congress is beyond those, even beyond the Solar System. Here, our goal is the next star system, with a sophisticated exploration of the technologies that are needed to send a precursor robotic ship many light years from Earth.

Even with such a long-‐term mission, the Moon remains the ideal spot to develop technologies, understand the low and microgravity space environment, assess the effects of radiation on our machines and structures, and learn how to build these so that they can self-‐repair and be reliable in this way for decades.

We will provide a background to current thinking and the engineering and other issues regarding the Moon as a viable place for humans to begin the long journey into space.

Jeff Bezos outlines vision of colonizing the solar system – The Space Reporter

Posted: at 3:48 am

At a celebration commemorating the 48th anniversary of the Apollo 11 moon landing, Blue Origin CEO Jeff Bezos argued for permanent settlements on the Moon and advocated colonization of the solar system as a means of making room for up to one trillion people.

Unlike other advocates for colonizing solar system worlds, Bezos does not base his position on the notion that humans need a new planet because Earth will someday be destroyed.

Instead, he sees it as a next step important to life on Earth.

We can harvest resources from asteroids, from Near-Earth Objects, and harvest solar energy from a much broader surface areaand continue to do amazing things. I want my grandchildrens grandchildren to be in a world of pioneering, exploration, and expansion throughout the solar system, he said.

Colonizing the solar system will free humanity from population concerns and open up resources capable of meeting up to one trillion peoples needs, Bezos emphasized.

Reusable rockets are the key to bringing down the expense of space travel and are a goal toward which Blue Origin is working, he noted.

An important step toward the larger goal of solar system colonization is returning to the Moon and establishing settlements on its poles to obtain water and gain access to solar power.

Its time for America to go back to the Moon, this time to stay. We know things about the Moon we didnt know back in the 1960s and 1970s, and with reusable rockets, we can do it affordably. We can get that done today, Bezos stated.

He also said he wants Blue Origin to operate a cargo service named Blue Moon, which would transport the supplies necessary for robots to build a human habitat on the Moon.

Blue Origin plans to take tourists to suborbital space with its New Shepard rocket but is also developing rockets capable of reaching orbit.

Bezos, who spoke on a stage at Cape Canaveral in front of the huge Saturn V rocket that launched the Apollo 11 mission to the Moon, was awarded the first annual Buzz Aldrin Innovation Award by Aldrins ShareSpace Foundation, a non-profit dedicated to inspiring and educating people about science, technology, engineering, arts, and math.

What makes cancer gene therapy so groundbreaking? – News@Northeastern

Posted: at 3:47 am

On July 12, a Food and Drug Administration panel unanimously recommended approval for the first-ever gene therapy treatment for cancer. The treatment, known as CTL019, is a T-cell therapy developed by the pharmaceutical company Novartis. It is tailored for each individual patient and has already been proven effective for treating a type of childhood leukemia. The New York Times reports that in a study of 63 patients, 52 of them went into remission after receiving the treatment.

Researchers have long been working to perfect gene therapy for a variety of cancers, but CTL019 will be the first to reach the market. If the FDA moves to approve CTL019, the decision could open the door for more gene therapy treatments for other diseases.

Mansoor Amiji is University Distinguished Professor inthe Department of Pharmaceutical Sciences at Northeastern. His research focuses on the development of targeted therapies, including gene therapy, for treatment of the most lethal cancers, such as pancreatic, lung, ovarian, and brain tumors, as well as other chronic diseases. For one project, Amijis lab is interested in reprograming immune cells through genetic engineering to become more effective in treating cancer and inflammatory diseases.

Here, Amiji explains more about gene therapy treatment and why the approval of CTL019 would be so significant.

It is still very early to suggest that cancer immunotherapy will lead to the ultimate cure or even long-term control of cancer, says distinguished professor Mansoor Amiji. But the opportunity to use the bodys own defenses to eradicate cancer cells is truly groundbreaking. Photo by Adam Glanzman/Northeastern University

CAR-T cell, or chimeric antigen receptor T-cell therapy, is one of the newer treatment options for cancer. Its based on the patients own immune system. In this approach, the patients T-cells are harvested and then genetically modified outside the body to produce engineered cells. The cells are then re-administered and can destroy the tumor. There have been studies conducted at various medical centers over the past several years, but this is the first time that the FDA committee is allowing a commercial pharmaceutical company to continue with the program, in this case for treatment of pediatric acute lymphoblastic leukemia.

Yes, cancer immunotherapy treatments, including CAR-T cell therapy, have been very successful in cancer treatment. More than 85 percent of patients treated with genetically engineered CAR-T cells are under remission, and that is unprecedented for cancer treatment options. However, it is still very early to suggest that cancer immunotherapy will lead to the ultimate cure or even long-term control of cancer and change it from a death sentence to a treatable chronic disease. But the opportunity to use the bodys own defenses to eradicate cancer cells is truly groundbreaking.

Genetic engineering focuses on using modified cells as drugs. In this approach, the cells are either removed from the body and genetically manipulated outside, such as in CAR-T cell therapy, or genetic constructs are delivered into specific cells in the body. For the latter, the genetic construct has to be packaged in a delivery vehiclenanoparticles, for exampleand be targeted to the right cell in the body. Conventional drugs work by inhibiting a specific molecular target, like a receptor on a cell or an enzyme involved in disease progression. Genetic therapies like CAR-T cell therapy are focused more on the treatment at the DNA or RNA level where the original defects reside. Thats why they can be significantly more effective than conventional therapies, and they also promise to be a lot safer.

The drug development process starts from preclinical discovery and then moves into the clinical phase where patients are treated with experimental methods. Typically, it takes about 10 to 15 years for a drug to go from early discovery up to the approval stage. However, there are exceptions when compelling early-stage clinical results are obtained that encourage the FDA to approve the treatment a lot faster. Also, once a trail-blazing concept like CAR-T cell therapy is approved, there are many other companies that are following behind with their own version of the treatment. Their products will be coming to the marketplace soon as well.
