Schlepping all that water to Mars would be costly and risky. That’s why NASA has engaged scientists and engineers since 2015 to identify deposits of Martian water ice that could be within reach of astronauts on the planet’s surface. ![]() In this illustration, NASA astronauts drill into the Mars’ subsurface. The agency is creating new maps that show where ice is most likely to be easily accessible to future astronauts. (NASA) «Read the rest of this article» Sections: Technology | No Comments
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 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’s OSIRIS-REx spacecraft completes Second Rehearsal, Ready to make Sample Collection
The approximately four-hour “Matchpoint” rehearsal took the spacecraft through the first three of the sampling sequence’s four maneuvers: the orbit departure burn, the “Checkpoint” burn and the Matchpoint burn. «Read the rest of this article» Sections: Technology | No Comments
NASA’s OSIRIS-REx Spacecraft to make second practice run before landing on Asteroid Bennu
On August 11th, the mission will perform its “Matchpoint” rehearsal – the second practice run of the Touch-and-Go (TAG) sample collection event. The rehearsal will be similar to the April 14th “Checkpoint” rehearsal, which practiced the first two maneuvers of the descent, but this time the spacecraft will add a third maneuver, called the Matchpoint burn, and fly even closer to sample site Nightingale – reaching an altitude of approximately 131 ft (40 m) – before backing away from the asteroid. ![]() This artist’s concept shows the trajectory and configuration of NASA’s OSIRIS-REx spacecraft during Matchpoint rehearsal, which is the final time the mission will practice the initial steps of the sample collection sequence before touching down on asteroid Bennu.

NASA’s Hubble Space Telescope captures Planetary Collision
What astronomers thought was a planet beyond our solar system has now seemingly vanished from sight. Though this happens in science fiction, such as Superman’s home planet Krypton exploding, astronomers are looking for a plausible explanation. One interpretation is that, rather than being a full-sized planetary object, which was first photographed in 2004, it could instead be a vast, expanding cloud of dust produced in a collision between two large bodies orbiting the bright nearby star Fomalhaut. Potential follow-up observations might confirm this extraordinary conclusion. ![]() This artist’s illustration depicts the collision of two 125-mile-wide icy, dusty bodies orbiting the bright star Fomalhaut, located 25 light-years away.

NASA releases First Names for Features on Asteroid Bennu
Benben Saxum and 11 other features on the asteroid are the first to receive official Bennu feature names approved by the International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features. ![]() This flat projection mosaic of asteroid Bennu shows the locations of the first 12 surface features to receive official names from the International Astronomical Union. The accepted names were proposed by NASA’s OSIRIS-REx team members, who have been mapping the asteroid in detail over the last year. Bennu’s surface features are named after birds and bird-like creatures in mythology, and the places associated with them.

NASA’s X-59 Quiet SuperSonic Technology aircraft uses parts from other aircrafts
Perfectly acceptable components from other aircraft – some major, some minor – are finding new life as parts installed on the X-59, an experimental airplane whose mission is to help open a new era of commercial supersonic air travel over land. ![]() NASA’s X-59 Quiet SuperSonic Technology aircraft being assembled at the Lockheed Martin Skunk Works® factory in Palmdale, California.
