Washington, D.C. – This is the most detailed view of Pluto’s terrain you’ll see for a very long time. This mosaic strip – extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14th, 2015 – now includes all of the highest-resolution images taken by the NASA probe. (Be sure to zoom in for maximum detail.)
With a resolution of about 260 feet (80 meters) per pixel, the mosaic affords New Horizons scientists and the public the best opportunity to examine the fine details of the various types of terrain on Pluto, and determine the processes that formed and shaped them.
Washington, D.C. – Pressurization of the Bigelow Expandable Activity Module (BEAM) began at 4:34pm EDT, and the eight tanks filled with air completed full pressurization of the module 10 minutes later at 4:44pm. BEAM’s pressure will be equalized with that of the International Space Station, where it will remain attached for a two-year test period.
The module measured just over 7 feet long and just under 7.75 feet in diameter in its packed configuration. BEAM now measures more than 13 feet long and about 10.5 feet in diameter to create 565 cubic feet of habitable volume. It weighs approximately 3,000 pounds.

Pasadena, CA – Since its launch five years ago, there have been three forces tugging at NASA’s Juno spacecraft as it speeds through the solar system. The sun, Earth and Jupiter have all been influential — a gravitational trifecta of sorts. At times, Earth was close enough to be the frontrunner.
More recently, the sun has had the most clout when it comes to Juno’s trajectory. Today, it can be reported that Jupiter is now in the gravitational driver’s seat, and the basketball court-sized spacecraft is not looking back.

Pasadena, CA – Scientists using radar data from NASA’s Mars Reconnaissance Orbiter (MRO) have found a record of the most recent Martian ice age recorded in the planet’s north polar ice cap.
The new results agree with previous models that indicate a glacial period ended about 400,000 years ago, as well as predictions about how much ice would have been accumulated at the poles since then.
The results, published in the May 27th issue of the journal Science, help refine models of the Red Planet’s past and future climate by allowing scientists to determine how ice moves between the poles and mid-latitudes, and in what volumes.

Greenbelt, MD – On September 8th, NASA’s OSIRIS-REx spacecraft is scheduled to launch for terra incognita: the unknown surface of the near-Earth asteroid Bennu. Like expeditions of old, OSIRIS-REx’s mission includes mapping the exotic terrain it explores.
Bennu is part of the debris left over from the formation of the solar system and is pristine enough to hold clues to that very early history. OSIRIS-REx – which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer – will study Bennu in detail and collect a sample to send to Earth for in-depth analysis. The mission also will investigate how pressure from sunlight influences the path of this traveling asteroid.

Pasadena, CA – Using data from NASA’s Great Observatories, astronomers have found the best evidence yet for cosmic seeds in the early universe that should grow into supermassive black holes.
Researchers combined data from NASA’s Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope to identify these possible black hole seeds. They discuss their findings in a paper that will appear in an upcoming issue of the Monthly Notices of the Royal Astronomical Society.

Greenbelt, MD – NASA’s first spacecraft designed to return a piece of an asteroid to Earth arrived Friday, May 20th, at the agency’s Kennedy Space Center in Florida, and has begun final preparations in advance of its September launch.
The Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer (OSIRIS-REx) spacecraft will undergo final testing and fueling prior to being moved to its launch pad. The mission has a 34-day launch period beginning on September 8th.
After launch, the OSIRIS-REx spacecraft will travel to the near-Earth asteroid Bennu and retrieve at least 60 grams (2.1 ounces) of pristine surface material and return it to Earth for study.

Huntsville, AL – NASA has tested a 3-D printed rocket engine turbopump with liquid methane – an ideal propellant for engines needed to power many types of spacecraft for NASA’s journey to Mars.
“This is one of the most complex rocket parts NASA has ever tested with liquid methane, a propellant that would work well for fueling Mars landers and other spacecraft,” said Mary Beth Koelbl, the manager of the Propulsions Systems Department at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Pasadena, CA – Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern Ocean are responsible.
A NASA/NOAA/university team led by Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, California, used satellite radar, sea surface temperature, land form and bathymetry (ocean depth) data to study the physical processes and properties affecting Antarctic sea ice.

Greenbelt, MD – New findings based on a year’s worth of observations from NASA’s Van Allen Probes have revealed that the ring current – an electrical current carried by energetic ions that encircles our planet – behaves in a much different way than previously understood.
The ring current has long been thought to wax and wane over time, but the new observations show that this is true of only some of the particles, while other particles are present consistently.
Using data gathered by the Radiation Belt Storm Probes Ion Composition Experiment, or RBSPICE, on one of the Van Allen Probes, researchers have determined that the high-energy protons in the ring current change in a completely different way from the current’s low-energy protons.
