Set to launch next year, NASA's Psyche mission marks the first time the agency has set out to explore an asteroid richer in metal than rock or ice. More than 150 years have passed since novelist Jules Verne wrote "Journey to the Center of the Earth," but reality has yet to catch up with that science fiction adventure. While humans can't bore a path to our planet's metallic core, NASA has its sig

When Pluto passed in front of a star on the night of August 15, 2018, a Southwest Research Institute-led team of astronomers had deployed telescopes at numerous sites in the U.S. and Mexico to observe Pluto's atmosphere as it was briefly backlit by the well-placed star. Scientists used this occultation event to measure the overall abundance of Pluto's tenuous atmosphere and found compelling evid

Late-time small-body asteroid disruptions can protect the Earth

If an asteroid is determined to be on an Earth-impacting trajectory, scientists typically want to stage a deflection, where the asteroid is gently nudged by a relatively small change in velocity, while keeping the bulk of the asteroid together.

A kinetic impactor or a standoff nuclear explosion can achieve a deflection.

Working overtime: NASA's deep space atomic clock completes mission

For more than two years, NASA's Deep Space Atomic Clock has been pushing the timekeeping frontiers in space. On Sept. 18, 2021, its mission came to a successful end.

The instrument is hosted on General Atomics' Orbital Test Bed spacecraft that was launched aboard the Department of Defense Space Test Program 2 mission June 25, 2019. Its goal: to test the feasibility of using an onboard atomic clock to improve spacecraft navigation in deep space.

Currently, spacecraft rely on ground-based atomic clocks. To measure a spacecraft's trajectory as it travels beyond the Moon, navigators use these timekeepers to precisely track when those signals are sent and received. Because navigators know that radio signals travel at the speed of light (about 186,000 miles per second, or 300,000 kilometers per second), they can use these time measurements to calculate the spacecraft's exact distance, speed, and direction of travel.

On 4 October 2021 ESA astronaut Thomas Pesquet became commander of the International Space Station, taking over from Japanese Aerospace Exploration Agency astronaut and fellow Crew-2 member Akihiko Hoshide. Thomas will hold this role until shortly before Crew-2 return to Earth in November. Thomas officially accepted his new position during a traditional ceremony, broadcast live from the International Space Station, where a symbolic handover of a key from Aki to Thomas denoted the change of command. The full title of this role is International Space Station crew commander. While overall command of the Station lies with ground-based
