NASA picks Four Small Mission Concepts to Study the Universe
“The principal investigators of these concept studies bring innovative, out-of-the-box thinking to the problem of how to do high-impact astrophysics experiments on a small budget,” said Thomas H. Zurbuchen, associate administrator of NASA’s Science Mission Directorate. “Each of the proposed experiments would do something no other NASA telescope or mission can do, filling important gaps in our understanding of the universe as a whole.” ![]() As neutron stars collide, some of the debris blasts away in particle jets moving at nearly the speed of light, producing a brief burst of gamma rays.

NASA model suggests Europa’s Plumes of Water Vapor could come from within it’s Icy Crust
Europa scientists have considered the possible plumes on Europa a promising way to investigate the habitability of Jupiter’s icy moon, especially since they offer the opportunity to be directly sampled by spacecraft flying through them. ![]() This illustration of Jupiter’s icy moon Europa depicts a cryovolcanic eruption in which brine from within the icy shell could blast into space. A new model proposing this process may also shed light on plumes on other icy bodies. (Justice Wainwright) «Read the rest of this article» Sections: Technology | No Comments
NASA’s OSIRIS-REx Spacecraft touches surface of Asteroid Bennu, collects Samples
This well-preserved, ancient asteroid, known as Bennu, is currently more than 200 million miles (321 million kilometers) from Earth. ![]() NASA’s OSIRIS-REx mission readies itself to touch the surface of asteroid Bennu.

NASA releases Broadcast times for OSIRIS-REx Asteroid Sample Collection Activities
Live coverage of the spacecraft’s descent to the asteroid’s surface for its “Touch-And-Go,” or TAG, maneuver, which will be managed by Lockheed Martin Space near Denver, will begin at 4:00pm CT on NASA Television and the agency’s website. ![]() NASA’s OSIRIS-REx mission readies itself to touch the surface of asteroid Bennu.

NASA says “Echo Mapping” could be used to measure distance from Earth to distant Galaxies
Measuring the luminosity of a celestial object is challenging, especially with black holes, which don’t emit light. But the supermassive black holes that lie at the center of most galaxies provide a loophole: They often pull lots of matter around them, forming hot disks that can radiate brightly. ![]() A disk of hot material around a supermassive black hole emits a burst of visible light, which travels out to a ring of dust that subsequently emits infrared light. The blue arrows show the light from the disk moving toward the dust and the light from both events traveling toward an observer.

NASA uses Artificial Intelligence to find new Craters on Mars
The smaller the features, the more difficult they are to spot using Mars orbiters. But in this case – and for the first time – scientists spotted them with a little extra help: artificial intelligence (AI). ![]() The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter took this image of a crater cluster on Mars, the first ever to be discovered AI. The AI first spotted the craters in images taken the orbiter’s Context Camera; scientists followed up with this HiRISE image to confirm the craters.

NASA OSIRIS-REx Spacecraft prepares for Touch-And-Go mission to asteroid Bennu
On October 20th, 2020 the mission will perform the first attempt of its Touch-And-Go (TAG) sample collection event. This series of maneuvers will bring the spacecraft down to site Nightingale, a rocky area 52 ft (16 m) in diameter in Bennu’s northern hemisphere, where the spacecraft’s robotic sampling arm will attempt to collect a sample. ![]() This artist’s concept shows NASA’s OSIRIS-REx spacecraft descending towards asteroid Bennu to collect a sample of the asteroid’s surface.

NASA investigates why Asteroid Bennu is shedding material into Space
Now, after more than a year and a half up close with Bennu, they’re starting to better understand these dynamic particle-ejection events. ![]() This mosaic image of asteroid Bennu is composed of 12 images collected on Dec. 2, 2018, by the OSIRIS-REx spacecraft’s PolyCam instrument from a range of 15 miles (24 kilometers).
