Contact binary asteroids are common, but we've never seen one form. Now, researchers want to make one

Ever want to play a game of cosmic billiards? That's commonly how the DART mission was described when it successfully changed the orbit of a near-Earth asteroid last year. If you want an idea of how it works, just Google it and an Easter egg from the search giant will give you a general idea. But DART was more like trying to brute force a billiards break—there are many other things you can do with a set of asteroids and impactors on the galactic stage. One of the more interesting is to try to force two asteroids together to form a "contact binary"—the goal of a mission design put forward by a group of scientists from Cornell in a recent paper in Acta Astronautica.
Colby Merill and his colleagues at Cornell's Mechanical and Aerospace Engineering department first explain why such a mission would be a good idea.
NASA tests in-flight capability of Artemis moon rocket engine

NASA conducted the third RS-25 engine hot fire in a critical 12-test certification series Nov. 29, demonstrating a key capability necessary for flight of the SLS (Space Launch System) rocket during Artemis missions to the moon and beyond.
NASA is conducting the series of tests to certify new manufacturing processes for producing RS-25 engines for future deep space missions, beginning with Artemis V.
NASA's 6-pack of mini-satellites ready for their moment in the sun

Most NASA missions feature one spacecraft or, occasionally, a few. The agency's Sun Radio Interferometer Space Experiment (SunRISE) uses half a dozen. This month, mission members completed the construction of the six identical cereal box-size satellites, which will now go into storage and await their final testing and ride to space.
