NASA’s OSIRIS-REx is one rehearsal away from touching asteroid Bennu

NASA’s first asteroid sampling spacecraft is making final preparations to grab a sample from asteroid Bennu’s surface. Next week, the OSIRIS-REx mission will conduct a second rehearsal of its touchdown sequence, practicing the sample collection activities one last time before…

As many as six billion Earth-like planets in our galaxy, according to new estimates

To be considered Earth-like, a planet must be rocky, roughly Earth-sized and orbiting Sun-like (G-type) stars. It also has to orbit in the habitable zones of its star–the range of distances from a star in which a rocky planet could host liquid water, and potentially life, on its surface.

NASA’s Curiosity rover finds clues to chilly ancient Mars buried in rocks

By studying the chemical elements on Mars today — including carbon and oxygen — scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life. Weaving this story, element by…

Galactic cosmic rays now available for study on Earth, thanks to NASA

To better understand and mitigate the health risks faced by astronauts from exposure to space radiation, we ideally need to be able to test the effects of Galactic Cosmic Rays (GCRs) here on Earth under laboratory conditions. An article publishing…
