Q&A with Earl Maize, Cassini project manager (members only)

The work isn’t over for NASA’s Ingenuity Mars helicopter. Engineers hope to fly the rotorcraft four more times in the next two weeks before calling it quits on the pioneering technology experiment, which accomplished the first powered flight of an aircraft on another planet Monday.

Two U.S. Air Force cargo planes delivered the Mars 2020 rover, cruise stage, descent module and the Mars Helicopter to the Kennedy Space Center in Florida this week for final assembly, fueling and mounting atop a United Launch Alliance Atlas 5 rocket in preparation for liftoff in July.

A new flyby mission selected by the European Space Agency this week for launch in 2028 will be the first to intercept a new comet or interstellar object fresh from the frozen depths of the outer solar system, or beyond.
