The Innovative Technology Partnerships Office at NASA's Goddard Space Flight Center in Greenbelt, Maryland, announced the release of its core Flight System (cFS) Application Suite to the public. The cFS application suite is composed of 12 individual Command and Data Handling (C&DH) flight software applications that together create a reusable library of common C&DH functions.
The cFS application suite allows developers to rapidly configure and deploy a significant portion of the C&DH software system for new missions, test platforms and prototypes, resulting in reduced schedule and cost. The cFS framework takes advantage of a rich heritage of successful NASA Goddard flight software efforts and addresses the challenges of rapidly increasing software development costs and schedules due to constant changes and advancements in hardware. Flight software complexity is expected to increase dramatically in coming years and the cFS provides a means to manage the growth and accommodate changes in flight system designs.
The cFS is currently being used by the Core Observatory of NASA's Global Precipitation Measurement (GPM) mission, launched on Feb. 27, 2014, from Tanegashima Space Center in Japan, and it has also been used by NASA's Ames Research Center in Moffett Field, California, on their most recent mission, the NASA Lunar Atmosphere and Dust Environment Explorer (LADEE), which launched Sept. 6, 2013. Other centers such as NASA's Marshall Space Flight Center in Huntsville, Alabama, NASA's Glenn Research Center in Cleveland, Ohio, and NASA's Johnson Space Center in Houston are currently using the cFS as well.
The core Flight Executive (cFE) and the Operating System Abstraction Library (OSAL) are two cFS components previously released as open source. These two components provide a platform-independent application runtime environment. The 12 applications in this release provide C&DH functionality common to most spacecraft Flight Software (FSW) systems.
This means the current suite of cFS open source applications now provide a complete FSW system including a layered architecture with user-selectable and configurable features. These architectural features coupled with an implementation targeted for embedded software platforms makes the cFS suitable for reuse on any number of flight projects and/or embedded software systems at very significant cost savings. Each component in the system is a separate loadable file and are available to download free of cost at the links listed in the table.
The complete cFS software suite will fully support the cFS user community and future generations of cFS spacecraft platforms and configurations. The cFS community expects the number of reusable applications to continue to grow as the user community expands.

NASA Wednesday announced more details in its plan for its Asteroid Redirect Mission (ARM), which in the mid-2020s will test a number of new capabilities needed for future human expeditions to deep space, including to Mars. NASA also announced it has increased the detection of near-Earth asteroids by 65 percent since launching its asteroid initiative three years ago.
For ARM, a robotic spacecraft will capture a boulder from the surface of a near-Earth asteroid and move it into a stable orbit around the moon for exploration by astronauts, all in support of advancing the nations journey to Mars.
"The Asteroid Redirect Mission will provide an initial demonstration of several spaceflight capabilities we will need to send astronauts deeper into space, and eventually, to Mars," said NASA Associate Administrator Robert Lightfoot. "The option to retrieve a boulder from an asteroid will have a direct impact on planning for future human missions to deep space and begin a new era of spaceflight."
The agency plans to announce the specific asteroid selected for the mission no earlier than 2019, approximately a year before launching the robotic spacecraft. Before an asteroid is considered a valid candidate for the mission, scientists must first determine its characteristics, in addition to size, such as rotation, shape and precise orbit. NASA has identified three valid candidates for the mission so far: Itokawa, Bennu and 2008 EV5. The agency expects to identify one or two additional candidates each year leading up to the mission.
Following its rendezvous with the target asteroid, the uncrewed ARM spacecraft will deploy robotic arms to capture a boulder from its surface. It then will begin a multi-year journey to redirect the boulder into orbit around the moon.
Throughout its mission, the ARM robotic spacecraft will test a number of capabilities needed for future human missions, including advanced Solar Electric Propulsion (SEP), a valuable capability that converts sunlight to electrical power through solar arrays and then uses the resulting power to propel charged atoms to move a spacecraft. This method of propulsion can move massive cargo very efficiently. While slower than conventional chemical rocket propulsion, SEP-powered spacecraft require significantly less propellant and fewer launches to support human exploration missions, which could reduce costs.
Future SEP-powered spacecraft could pre-position cargo or vehicles for future human missions into deep space, either awaiting crews at Mars or staged around the moon as a waypoint for expeditions to the Red Planet.
ARM's SEP-powered robotic spacecraft will test new trajectory and navigation techniques in deep space, working with the moon's gravity to place the asteroid in a stable lunar orbit called a distant retrograde orbit. This is a suitable staging point for astronauts to rendezvous with a deep space habitat that will carry them to Mars.
Before the piece of the asteroid is moved to lunar orbit, NASA will use the opportunity to test planetary defense techniques to help mitigate potential asteroid impact threats in the future. The experience and knowledge acquired through this operation will help NASA develop options to move an asteroid off an Earth-impacting course, if and when that becomes necessary.

As NASA's Dawn spacecraft closes in on Ceres, new images show the dwarf planet at 27 pixels across, about three times better than the calibration images taken in early December. These are the first in a series of images that will be taken for navigation purposes during the approach to Ceres.
Over the next several weeks, Dawn will deliver increasingly better and better images of the dwarf planet, leading up to the spacecraft's capture into orbit around Ceres on March 6. The images will continue to improve as the spacecraft spirals closer to the surface during its 16-month study of the dwarf planet.
"We know so little about dwarf planet Ceres. Now, Dawn is ready to change that," said Marc Rayman, Dawn's chief engineer and mission director, based at NASA's Jet Propulsion Laboratory in Pasadena, California.
The best images of Ceres so far were taken by NASA's Hubble Space Telescope in 2003 and 2004. This most recent images from Dawn, taken January 13, 2015, at about 80 percent of Hubble resolution, are not quite as sharp. But Dawn's images will surpass Hubble's resolution at the next imaging opportunity, which will be at the end of January.
"Already, the [latest] images hint at first surface structures such as craters," said Andreas Nathues, lead investigator for the framing camera team at the Max Planck Institute for Solar System Research, Gottingen, Germany.
Ceres is the largest body in the main asteroid belt, which lies between Mars and Jupiter. It has an average diameter of 590 miles (950 kilometers), and is thought to contain a large amount of ice. Some scientists think it's possible that the surface conceals an ocean.
Dawn's arrival at Ceres will mark the first time a spacecraft has ever visited a dwarf planet.

NASA has released new details on how it plans to boldly go to an asteroid and come back with a bit of it. The Asteroid Redirect Mission (ARM) is part of the space agency's Asteroid Initiative announced in 2013, which envisions the capture and return of an asteroid to lunar orbit for study by astronauts as a rehearsal for a later mission to Mars.
Scheduled to begin in 2020, the purpose of the ARM is to test new technologies and techniques that would be needed for later manned deep space missions while learning more about asteroids and how to defend the Earth against them. This involves sending a robotic spacecraft to collect a boulder from a near-Earth asteroid, then return it to lunar orbit, where a later manned mission will rendezvous to retrieve samples.
The ARM will begin with an unmanned Asteroid Redirect Vehicle being sent to a target asteroid, which has yet to be selected. The collector spacecraft will travel to the asteroid on a multi-year trajectory using Solar Electric Propulsion (SEP). This uses solar panels to power ion thrusters that provide a very low, constant thrust for years on end by charging xenon atoms and accelerating them. The system is currently being used on the Dawn mission and NASA hopes that it could one day be used to preposition supply craft for a Mars mission.
Once at the asteroid, the spacecraft will select a likely boulder and collect it using its robotic arms equipped with microspine grippers, then lift it off by hopping and using thrusters. NASA says it will take about six years to bring the boulder back to Earth. On return, the Asteroid Redirect Vehicle will go into a distant retrograde orbit around the Moon at a distance of 61,500 km (38,200 mi), which is very stable and requires relatively little energy to reach. This will not only place the returned boulder within the reach of astronauts, it will also test the orbit's suitability for parking future interplanetary spacecraft, such as a Mars mission habitat.
Another objective of the asteroid return mission will be to test methods for defending the Earth against asteroid strikes. One of these will be to use the mass of the Asteroid Redirect Vehicle and its boulder cargo as an interplanetary tug called a gravity tractor. By going into a halo orbit around the target asteroid and orienting in a particular direction, this will pull the asteroid minutely and while this fractional change might not seem like much, over hundreds and millions of miles that deflection can add up, making the difference between a hit and a miss.
After the boulder has been placed into lunar orbit in the mid-2020s, NASA will launch an Orion spacecraft with two astronauts aboard on a 25-day mission to rendezvous with the asteroid fragment for study and collecting samples. While there, the astronauts will test new sensors and a new docking system to link the Orion and the Asteroid Redirect Vehicle, after which the astronauts will spacewalk to the boulder using a new generation of spacesuits.
NASA says it will select a target asteroid by 2019, which will be about a year before the unmanned collector spacecraft is launched. These will be assessed based on size, shape, rotation, and orbit. The current candidates include the asteroids Itokawa, Bennu, and 2008 EV5, but up to two more candidates will be added each year until the mission starts.
The collection of asteroid samples will also help train astronauts and mission managers in how to collect and secure samples for return on future Mars missions.
"The Asteroid Redirect Mission will provide an initial demonstration of several spaceflight capabilities we will need to send astronauts deeper into space, and eventually, to Mars," says NASA Associate Administrator Robert Lightfoot. "The option to retrieve a boulder from an asteroid will have a direct impact on planning for future human missions to deep space and begin a new era of spaceflight."
The agency is asking the US Congress for US$50 million towards the mission in the 2016 budget.

New Horizons will reach Pluto in July, despite being cancelled twice during development. Alan Sterns determination was crucial to making the mission happen. In this illustration, Plutos moon Charon is the crescent in the background. (Credit: JHUAPL/SwRI)
You dont have to wonder what is on Alan Sterns mind. The planetary scientist and former NASA associate administrator is a relentless champion of all things Pluto; he is both the principal investigator and the prime mover behind the New Horizons mission, which will fly past Pluto and its moons this July 14. In advance of the encounter, Sterns passion is building to a white heat, and he is letting everyone know it.
The excitement is infectious. Pluto is looking far more interesting than researchers realized just a few years ago. Ironically, its scientific importance has skyrocketed in the years since the International Astronomical Union demoted Pluto to dwarf planet. Recent theoretical models indicate that the Kuiper Beltthe population of objects, including Pluto, that orbits beyond Neptuneis key to understanding the early evolution of the outer solar system. It is home to multiple big, round objects that record the movements of water and organic chemicals at the time when Earth was forming.
Call these things in the Kuiper Belt dwarf planets, call them planets (or call them Plutoids and duck before Stern comes after you), whatever. They are major players in the suns family, many of them larger than any asteroid, and Pluto is the brightest and most complex of them all. Stern is a Pluto obsessive, but more and more it looks like the science is on his side: Pluto really is something special, and the New Horizons encounter promises to be a unique experience. Here, Stern makes his caseand reveals surprising details about another great mission that almost happened.
For more about Pluto and other space news, follow me on Twitter: @coreyspowell
You describe New Horizons as the first mission to the outer solar systema description that would surprise a lot of people who work on, say, the Cassini mission at Saturn.
Alan Stern: One of the implications of the discovery of the Kuiper Belt and its many small planets is that many scientists now think of the solar system as having not two but three zones. These are, as you go outward from the Sun, the inner rocky terrestrial planets [including Earth], the ice and gas giants [Jupiter and its kin], and the Kuiper Beltthe largest of the three zones, and the one with the most planets. When you think of the architecture of the solar system this way, you see that the missions that explored Jupiter, Saturn, Uranus, and Neptune were really missions to the middle solar system. Then New Horizons becomes the first true mission to the outer planets, the first probe to explore the third zone.
The whole is it a planet debate keeps coming up, but it seems more confusing than enlightening. I liked the recent essay by William McKinnon of Washington University, who defined Pluto in terms of its scientific significance. He called it a beacon to an unexplored solar realm and sentinel of the third zone.
No question, Pluto is the belle of the ball. Its got everything! There are lots of really interesting little planets out there in the Kuiper Belt, but Plutos the only one thats got all the cool attributes. Its the only one with an atmosphere that we know of, its a binary planet, its got seasons and global change, its got more kinds of volatiles on its surface than any other planet out there, and its got a really complicated satellite system.
I think that if you asked 100 leading planetary scientists and said make a table, list the interesting aspects of dwarf planets in the Kuiper Belt, the list for Pluto would be longer than for any other object on every persons list. Thats not me cheerleading, its just a statement of fact. We know more about Pluto, but it seems to have all the goodies. Its the whole package.

TIME Ideas Innovation When Technology Helps Us Become More Human Corbis The human desire to help combined with new technological tools could create solutions to some of the world's biggest problems
It was Tuesday January 12, 2010, and the Haitian capital had just been hit with a massive earthquake.
Far away in Boston, Fletcher School PhD candidate Patrick Meier was faced with a wrenching problem: his wife, also a Fletcher student, was in Port-au-Prince, and he couldnt get in touch with her. The anxiety was nearly paralyzing, he said at a recent event at New America. I needed to focus, to do something anything.
A specialist in so-called liberation technologies, Meier realized there was one thing he could do: create a crisis map of the disaster, mapping everything from CNN reports to Tweets. The job of finding and geo-referencing news reports and social media postings soon became too big for him, and Meier reached out to friends at Fletcher and beyond to assist him.
By the following Saturday, Meier found himself commanding a nerve center of fellow volunteerssome there in person, others in touch via Internetfrom his dorm room. Together, they were sorting and tagging Tweets using the Ushahidi mapping platform. They were also using Google Maps to support search and rescue efforts on the ground. Eventually, their efforts led to working with a Haitian telecom provider to launch a SMS help line service that could send messages directly into the groups inbox.
Because many of the volunteers hailed from the Haitian diaspora abroad, Meiers group was able to use high resolution satellite imagery to update the woefully out-of-date maps of Port-au-Prince on Open Street Maps.
The work that Meier and his group did accomplished more than helping him focus on something else while he waited to hear word from his wife (who was thankfully unharmed). They connected missing people with relief efforts on the ground. The US Marine Corps commended them, with one contact claiming their crisis map was saving lives every day.
But after Haiti, the nerve center they had created was still active and wondering: what was next? With the assistance of the Internet and social media, volunteers in their own homes dubbed by Meier as Digital Jedis now appeared to have an important place in international disaster response. With this in mind, Meier founded the Digital Humanitarian Network, which serves as a middle-man between volunteer and technical networks, and the digital networks of volunteers who can assist them when disaster strikes.
These digital humanitarians who have joined the network, and the basic human altruism that animates them, have inspired Meiers new book: Digital Humanitarians: How Big Data is Changing the Face of Humanitarian Response. To Meier, there are two common threads in the examples of digital humanitarianism in the new publication: technology and hope. What matters is combining these two essential elements to create projects that truly work combining the human desire to help with new technological tools that can enhance human abilities.
One major problem with data-driven disaster response is volume: for example, the volunteers in Haiti worked tirelessly, but they were only able to categorize so much data themselves. An essential problem with tech-savvy disaster response, Meier argues, is that we have collectively moved from a period where responders had too little data to one where they often have entirely too much.

Sydney Medical School at the University of Sydney and philanthropic organisation The Balnaves Foundation are giving next-generation medical leaders a kick start via a new $1m program to boost the competitive grant funding success of early career researchers.
The 'Early Career Researcher Kick Start Grants' is a new three-year joint initiative made possible through a significant commitment by The Balnaves Foundation. The gift will build on a successful seven-year investment program by the medical school, which is solving a major challenge facing all early career researchers.
"Early career researchers are the lifeblood of all successful medical research projects and face an increasing battle for grant funding due to their limited body of work, lack of experience and intense competition," says Professor Bruce Robinson, Dean of Sydney Medical School.
"But they face a classic dilemma: they need research expertise to receive grant funding, but they need grant funding to develop research expertise."
Currently only 15 per cent of all National Health and Medical Research Council grant applications are successful, a figure that has declined steadily over the past five years.
Today, 28 early career researchers from Sydney Medical School have received 'Kick Start' grants to fund pilot projects that will help them compete for future competitive grant funding, and help shape the future of medical research in Australia.
"The partnership between Sydney Medical School and the Balnaves Foundation will provide a crucial building block, upon which early career researchers can take a significant leap forward in their career and contribute towards meaningful health outcomes," says Neil Balnaves AO, Founder of the Balnaves Foundation.
"It is an example of how philanthropic partnerships can significantly help to address key national issues and provide support for outstanding medical research in Australia."
"Young people often have 'out of the box' ideas and this type of research is often where breakthroughs occur. We want the novel ideas of these 28 young researchers to have the opportunity of coming to fruition and are excited to follow their progress over the next few years," says Mr Balnaves.
The joint program is modelled on the Sydney Medical School's seven year investment to build the capacity and necessary experience for early career researchers to succeed.
