MarCO or Mars Cube One is an experimental mission that is sending two tiny spacecraft along with InSight to Mars. If successful, they will relay real-time telemetry from InSight to Earth during the landing.
Some of the biggest discoveries we make in planetary science rely on the seemingly simple act of picking up and analyzing pieces of other worlds. When things go awry, scientists and engineers can sometimes squeeze amazing science out of a tough situation.
As OSIRIS-REx speeds away from Earth, it’s been turning on and testing out its various engineering functions and science instruments. Proof of happy instrument status has come from several cameras, including the star tracker, MapCam, and StowCam.
Ever since its landing, Philae has been elusive. It went silent just three days later and never returned any more science data, though it made brief contact with the orbiter last summer. Now, just a month until the planned end of the Rosetta mission, the orbiter has finally located the lander in a stunning high-resolution view of the surface.
The OSIRIS-REx mission passed its flight readiness review yesterday, clearing the way for the spacecraft to launch on Thursday, September 8. Here's a schedule of next week's NASA TV briefings and a photo album of the launch preparations.
