NASA’s OSIRIS-REx spacecraft takes close up image of asteroid Bennu

 

NASA’s Goddard Space Flight Center 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – This trio of images acquired by NASA’s OSIRIS-REx spacecraft shows a wide shot and two close-ups of a region in asteroid Bennu’s northern hemisphere.

The wide-angle image (left), obtained by the spacecraft’s MapCam camera, shows a 590-foot (180-meter) wide area with many rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks.

NASA Researchers are creating Alien Atmospheres on Earth

 

NASA Jet Propulsion Laboratory 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers at NASA’s Jet Propulsion Laboratory in Pasadena, California, are cooking up an alien atmosphere right here on Earth. In a new study, JPL scientists used a high-temperature “oven” to heat a mixture of hydrogen and carbon monoxide to more than 2,000 degrees Fahrenheit (1,100 Celsius), about the temperature of molten lava.

The aim was to simulate conditions that might be found in the atmospheres of a special class of exoplanets (planets outside our solar system) called “hot Jupiters.”

NASA’s Oceans Melting Greenland mission still making discoveries

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Only seven months after NASA’s Oceans Melting Greenland (OMG) mission wrapped its last field campaign on the world’s largest island, an OMG crew is back in Greenland to collect more data.

With two or three field projects a year since 2016, no wonder OMG has made the most comprehensive measurements yet of how ocean water lapping at the undersides of Greenland’s melting glaciers affects them. All that data has answered a lot of existing questions – and it’s raised plenty of new ones.

NASA Goddard Technologists and Scientists Prepare for a New Era of Human Exploration

 

Written by Lori Keesey
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA scientists, engineers, and technologists are preparing for a new era of human exploration at the Moon, which includes a new launch system, capsule, and lunar-orbiting outpost that will serve as the jumping-off point for human spaceflight deeper into the Solar System.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is playing a vital role in these initiatives, particularly in the areas of communications and instrument development as evidenced by the recent award of five proposals under NASA’s Development and Advancement of Lunar Instrumentation (DALI) to advance spacecraft-based instrument for use in lunar-landing missions.

The technologies needed for sustainable exploration at the Moon will have to be powerful, multipurpose, and fast, said Jake Bleacher, Chief Scientist for the Human Exploration and Operations Mission Directorate.

Last Photos from NASA’s Opportunity Rover on Mars

 

NASA Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Over 29 days last spring, NASA’s Mars Exploration Rover Opportunity documented this 360-degree panorama from multiple images taken at what would become its final resting spot in Perseverance Valley. Located on the inner slope of the western rim of Endurance Crater, Perseverance Valley is a system of shallow troughs descending eastward about the length of two football fields from the crest of Endeavor’s rim to its floor.

“This final panorama embodies what made our Opportunity rover such a remarkable mission of exploration and discovery,” said Opportunity project manager John Callas of NASA’s Jet Propulsion Laboratory in Pasadena, California.

This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover's Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see. (NASA/JPL-Caltech/Cornell/ASU)

NASA’s Plans for traveling to the Moon Coming Together

 

NASA Headquarters  

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA will soon return humans to the Moon for decades to come, and the system that will transport astronauts from Earth to the Gateway Lunar Outpost near the Moon is literally coming together.

Building on progress in 2018, most of the major manufacturing for the first mission is complete, and this year, teams will focus on final assembly, integration, and testing, as well as early work for future missions.

NASA’s Lunar Reconnaissance Orbiter observes Water Movement on the Moon

 

NASA Goddard Space Flight Center 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Using an instrument aboard NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have observed water molecules moving around the dayside of the Moon.

A paper published in Geophysical Research Letters describes how Lyman Alpha Mapping Project (LAMP) measurements of the sparse layer of molecules temporarily stuck to the surface helped characterize lunar hydration changes over the course of a day.

Up until the last decade or so, scientists thought the Moon was arid, with any water existing mainly as pockets of ice in permanently shaded craters near the poles.

NASA study shows K Stars more likely to host Habitable Planets

 

NASA Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA says scientists looking for signs of life beyond our solar system face major challenges, one of which is that there are hundreds of billions of stars in our galaxy alone to consider. To narrow the search, they must figure out: What kinds of stars are most likely to host habitable planets?

A new study finds a particular class of stars called K stars, which are dimmer than the Sun but brighter than the faintest stars, may be particularly promising targets for searching for signs of life.

NASA reports SpaceX Crew Dragon Splashes down, Marks Success of First Commercial Crew Flight Test

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA passed a major milestone Friday in its goal to restore America’s human spaceflight capability when SpaceX’s Crew Dragon returned to Earth after a five-day mission docked to the International Space Station.

About 6 hours after departing the space station, Crew Dragon splashed down at 7:45am CST approximately 230 miles off the coast of Cape Canaveral, Florida. SpaceX retrieved the spacecraft from the Atlantic Ocean and is transporting it back to port on the company’s recovery ship.

Completing an end-to-end uncrewed flight test, Demo-1, SpaceX’s Crew Dragon departed the International Space Station at 1:32am CST Friday, March 8, 2019, and splashed down at 8:45 a.m. in the Atlantic Ocean about 200 nautical miles off the Florida coast. (NASA Television)

NASA reports SpaceX Crew Dragon set for Undock, Departure, Splashdown

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The SpaceX Crew Dragon’s hatch is closed and the stage is set for the Commercial Crew Program’s first undocking and return to Earth Friday. As NASA and SpaceX get ready for Friday’s splashdown, the Expedition 58 crew continued exploring a variety of space physics phenomena aboard the International Space Station.

The uncrewed SpaceX DM-1 mission has one final milestone and that is the safe return to Earth with a splashdown in the Atlantic Ocean around 7:45am CST Friday. The Crew Dragon will undock Friday at 1:31am from the Harmony module’s international docking adapter. NASA TV will broadcast the departure and return activities live.

The uncrewed SpaceX Crew Dragon spacecraft is the first Commercial Crew vehicle to visit the International Space Station. Here it is pictured with its nose cone open revealing its docking mechanism while approaching the station’s Harmony module on March 3rd, 2019. (NASA)
