"One of the things I really like about studying asteroids is how little we know about them," he says.
Rivkin, who studied Earth, Atmospheric, and Planetary Sciences as an undergrad at MIT, is now a planetary astronomer at the Johns Hopkins University Applied Physics Laboratory.
The team is actively testing the technique on the asteroid Didymos and its small moon Dimorphos. The DART probe launched on November 24, 2021, on a SpaceX Falcon 9, and the plan is to smash it into Dimorphos to see how the impact changes its orbit. Impact is expected on September 26, 2022.
China announces plans for a new asteroid-deflecting mission - The Verge
China's space agency plans to send a spacecraft to slam into an asteroid, knocking it into a new — and hopefully safer — orbit.
The country hasn't yet determined which asteroid to target. The mission was announced as one part of a larger new planetary defense effort, which will seek to catalog and monitor near-Earth asteroids, especially those that might pose a threat to our planet.

Once the primary mission of NASA’s OSIRIS-REx is complete, the spacecraft will head toward a new destination: near-Earth asteroid Apophis.
Once an asset is in space and functioning, it only makes sense to repurpose it and obtain the most science bang for the buck. In that vein, NASA announced yesterday that it will grant extensions for eight missions currently underway.
All of the bases in DNA and RNA have now been found in meteorites | Science News
Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA , scientists report April 26 in Nature Communications .
A few years ago, geochemist Yasuhiro Oba of Hokkaido University in Sapporo, Japan, and colleagues came up with a technique to gently extract and separate different chemical compounds in liquified meteorite dust and then analyze them.

NASA to extend OSIRIS-REx spacecraft for a mission to a second asteroid - AZPM
NASA has announced it will extend the University of Arizona-led OSIRIS-Rex mission after it returns to earth next year.
OSIRIS-REx will still swing by Earth in September 2023 as planned, but after dropping a capsule of samples collected from asteroid Bennu last year, it will remain in space to rendezvous with another asteroid, named Apophis.
