Andy Klesh, MarCO chief engineer, NASA JPL, left, and Annie Marinan, MarCO Systems Engineer, NASA JPL discuss NASA's Mars Cube One (MarCO) technology demonstration mission during a prelaunch media briefing, Thursday, May 3, 2018, at Vandenberg Air Force Base in California.
MarCO, which is a separate mission launched on the same rocket as NASA's InSight mission to Mars, will test new miniaturized deep space communication equipment.
MarCo and Insight began their journey to Mars on May 5, 2018.

Enceladus Flyby E-15 (Raw Image #6)
For an Earth observer on May 3, 2005, the Cassini spacecraft appeared to pass behind the rings, then Saturn, then the rings again (the red line). The discovered harmonic structure was found on both...
Saturn's Ring Rhythm #2
Saturn's moon Dione occults part of Saturn's distant rings while Tethys hovers below. Dione is 1,118 kilometers (695 miles) across, while Tethys is 1,071 kilometers, 665 miles) across. This image...
Pair to Compare
The spoke-producing region of the B ring displays fine-scale asymmetry in the azimuthal direction -- the direction along which the ring particles orbit Saturn -- from upper left to lower right acro...

Spiral density waves in Saturn's A ring reveal the gravitational signatures of distant moons as they subtly tug on the countless particles orbiting in the ring plane. Resulting from a process call...
Saturn's Watch Spiral
This image from NASA's Dawn spacecraft shows many linear or sinuous grooves crisscrossing the surface of asteroid Vesta. They were created when large pieces of debris grazed and scoured the surface.

Saturn's moon Rhea passes in front of Dione, as seen from the Cassini spacecraft. These images are part of a "mutual event" sequence in which one moon passes close to, or in front of, another. The...
Dione Beyond Rhea
This image from NASA's Cassini mission was taken on Nov. 27, 2012, with Cassini's narrow-angle imaging camera.
