GREENBELT, Md. (NASA PR) — NASA’s continued quest to explore our solar system and beyond received a boost of new information this week with three key missions proving not only that they are up and running, but that their science potential is exceptional. On Sept. 17, 2018, TESS — the Transiting Exoplanet Survey Satellite — shared its first science observations. Later in the week, the latest two missions to join NASA’s heliophysics fleet returned first light data: Parker Solar Probe, humanity’s first mission to “touch” the Sun, and GOLD, a mission that studies the dynamic boundary between Earth and space.
GREENBELT, Md. (NASA PR) — Three hundred and ten miles above our planet’s surface, near-Earth space is abuzz with action. Here begin the Van Allen Belts, a pair of concentric rings of fast-moving particles and intense radiation that extends more than 30,000 miles farther into space.

When astronauts land again on the surface of another world, their limited resources will allow for a short window of time each day to explore their new surroundings. Instruments designed to quickly reveal the terrain’s chemistry and form will help them understand the environments around them and how they change over time.
To protect precious hours available for extraterrestrial scientific investigations, a team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland — the Goddard Instrument Field Team (GIFT) — is testing and refining the chemical-analyzing and land-surveying tools that will assist future human explorers of places like the Moon and Mars.
NASA’s Ice, Cloud and land Elevation Satellite-2, or ICESat-2, a mission to measure the changing height of Earth’s ice, is scheduled to launch Saturday, Sept. 15, with a 40-minute window opening at 5:46 a.m. PDT (8:46 a.m. EDT).
The spacecraft will lift off from Space Launch Complex 2 (SLC-2) at Vandenberg Air Force Base in California on the final launch of a United Launch Alliance Delta II rocket. The U.S. Air Force 30th Space Wing weather officer reported they are predicting a 100 percent chance of favorable weather on launch day.

After traveling for two years and billions of kilometers from Earth, the OSIRIS-REx probe is only a few months away from its destination: the intriguing asteroid Bennu. When it arrives in December, OSIRIS-REx will embark on a nearly two-year investigation of this clump of rock, mapping its terrain and finding a safe and fruitful site from which to collect a sample.
REENBELT, Md. (NASA PR) — After an almost two-year journey, NASA’s asteroid sampling spacecraft, the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx), caught its first glimpse of asteroid Bennu last week and began the final approach toward its target. Kicking off the mission’s asteroid operations campaign on Aug. 17, the spacecraft’s PolyCam camera obtained the image from a distance of 1.4 million miles (2.2 million km).
OSIRIS-REx is NASA’s first mission to visit a near-Earth asteroid, survey the surface, collect a sample and deliver it safely back to Earth. The spacecraft has traveled approximately 1.1 billion miles (1.8 billion km) since its Sept. 8, 2016, launch and is scheduled to arrive at Bennu on Dec. 3.
GREENBELT, Md. (NASA PR) — Next month, NASA will launch into space the most advanced laser instrument of its kind, beginning a mission to measure – in unprecedented detail – changes in the heights of Earth’s polar ice.
NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second.
WASHINGTON (National Academies PR) – Despite significant cuts to NASA’s Planetary Science Division budget early in this decade, the space agency has made impressive progress in meeting goals outlined in the 2013-2022 planetary decadal survey by the National Academies of Sciences, Engineering, and Medicine, says a new midterm assessment from the National Academies.
The report notes that the agency met or exceeded the decadal survey’s recommendations for funding research and analysis, and for technology programs. However, NASA has not achieved the recommended timeline for New Frontiers and Discovery missions for the decade. At least one more New Frontiers mission and three Discovery missions should be selected before the end of the decade in order to achieve the schedule recommended in Vision and Voyages. (more…)
GREENBELT, Md. (NASA PR) — Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere and act as a blanket to warm the planet.
GREENBELT, Md. (NASA PR) — NASA’s Transiting Exoplanet Survey Satellite has started its search for planets around nearby stars, officially beginning science operations on July 25, 2018. TESS is expected to transmit its first series of science data back to Earth in August, and thereafter periodically every 13.5 days, once per orbit, as the spacecraft makes it closest approach to Earth. The TESS Science Team will begin searching the data for new planets immediately after the first series arrives.
“I’m thrilled that our new planet hunter mission is ready to start scouring our solar system’s neighborhood for new worlds,” said Paul Hertz, NASA Astrophysics division director at Headquarters, Washington. “Now that we know there are more planets than stars in our universe, I look forward to the strange, fantastic worlds we’re bound to discover.”
TESS is NASA’s latest satellite to search for planets outside our solar system, known as exoplanets. The mission will spend the next two years monitoring the nearest and brightest stars for periodic dips in their light. These events, called transits, suggest that a planet may be passing in front of its star. TESS is expected to find thousands of planets using this method, some of which could potentially support life.
TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission.
Additional partners include Northrop Grumman, based in Falls Church, Virginia; NASA’s Ames Research Center in California’s Silicon Valley; the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts; MIT’s Lincoln Laboratory in Lexington, Massachusetts; and the Space Telescope Science Institute in Baltimore. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.
GREENBELT, Md. (NASA PR) — Early on an August morning, the sky near Cape Canaveral, Florida, will light up with the launch of Parker Solar Probe. No earlier than Aug. 6, 2018, a United Launch Alliance Delta IV Heavy will thunder to space carrying the car-sized spacecraft, which will study the Sun closer than any human-made object ever has.

GREENBELT, Md. (NASA PR) — Satellites are crucial to our everyday lives, but cost hundreds of millions of dollars to manufacture and launch. Currently, they are simply decommissioned when they run out of fuel. However, there is a better way: satellite servicing, which can make spaceflight more sustainable, affordable and resilient. NASA’s satellite servicing technologies are opening up a new world where space robots diagnose, maintain and extend a spacecraft’s life.
At NASA’s Goddard Space Flight Center, a 10 by 16-foot robot tests satellite servicing capabilities on Earth before they’re put to use in space. Sitting on top of the six-legged hexapod is a partial mock-up of a satellite. Mounted to a panel close by is an advanced robotic arm. Together, these robots practice a calculated dance. As the hexapod moves, it mimics microgravity as the robotic arm reaches out to grab the satellite.
At NASA, we’re working to prove the combination of technologies necessary to robotically refuel a satellite in orbit that was not designed to be serviced. The same technologies developed for the Restore-L project will advance in-orbit repair, upgrade and assembly capabilities.
The ground demonstrations take place in Goddard’s Robotic Operations Center. The hexapod robot was built for NASA by Mikrolar, a New Hampshire-based company.
GREENBELT, Md. (NASA PR) — NASA’s Human Exploration and Operations and Science Mission Directorates are collaborating to make interplanetary internet a reality.
They’re about to demonstrate Delay/Disruption Tolerant Networking, or DTN – a technology that sends information much the same way as conventional internet does. Information is put into DTN bundles, which are sent through space and ground networks to its destination.
GREENBELT, Md. (NASA PR) — After a successful launch on April 18, 2018, NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite, is currently undergoing a series of commissioning tests before it begins searching for planets. The TESS team has reported that the spacecraft and cameras are in good health, and the spacecraft has successfully reached its final science orbit. The team continues to conduct tests in order to optimize spacecraft performance with a goal of beginning science at the end of July.
Every new mission goes through a commissioning period of testing and adjustments before beginning science operations. This serves to test how the spacecraft and its instruments are performing and determines whether any changes need to be made before the mission starts observations.

GREENBELT, Md. (NASA PR) — New tracking data confirms that NASA’s OSIRIS-REx spacecraft successfully completed its second Deep Space Maneuver (DSM-2) on June 28. The thruster burn put the spacecraft on course for a series of asteroid approach maneuvers to be executed this fall that will culminate with the spacecraft’s scheduled arrival at asteroid Bennu on Dec. 3.
The DSM-2 burn, which employed the spacecraft’s Trajectory Correction Maneuver (TCM) thruster set, resulted in a 37 miles per hour (16.7 meters per second) change in the vehicle’s velocity and consumed 28.2 pounds (12.8 kilograms) of fuel.
Tracking data from the Deep Space Network provided preliminary confirmation of the burn’s execution, and the subsequent downlink of telemetry from the spacecraft shows that all subsystems performed as expected.
DSM-2 was OSIRIS-REx’s last deep space maneuver of its outbound cruise to Bennu. The next engine burn, Asteroid Approach Maneuver 1 (AAM-1), is scheduled for early October. AAM-1 is a major braking maneuver designed to slow the spacecraft’s speed from approximately 1,130 to 320 miles per hour (506.2 to 144.4 meters per second) relative to Bennu and is the first of four asteroid approach maneuvers scheduled for this fall.
NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering and the safety and mission assurance for OSIRIS-REx. Dante Lauretta of the University of Arizona, Tucson, is the principal investigator, and the University of Arizona also leads the science team and the mission’s observation planning and processing. Lockheed Martin Space in Denver built the spacecraft and is providing spacecraft flight operations. Goddard and KinetX Aerospace are responsible for navigating the OSIRIS-REx spacecraft. OSIRIS-REx is the third mission in NASA’s New Frontiers Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the agency’s New Frontiers Program for its Science Mission Directorate in Washington.
