One of NASA's MarCO twin ships – MarCO-B, aka Wall-E – captured this image on October 2, 2018. It was the first time that this type of inexpensive vessel of the size of a briefcase, called CubeSat, imaged Mars. See an annotated image below. Image via NASA / JPL-Caltech.
When you're the only CubeSats to have traveled to Mars, it's easy to create a whole series of firsts. This week (22 October 2018), NASA has released the very first image of CubeSat of the Red Planet, its MarCO mission, currently on its way to Mars, due to arrive in November. Of course, the image is not very dramatic, but imaging is not the task for MarCO-A and MarCO-B, dubbed EVE and Wall-E by NASA Jet Propulsion Engineers. . Instead, the MarCOs – launched May 5 with NASA's InSight lander – are testing the role that CubeSats could play in future space missions.
InSight will land on Mars next month. This more elaborate mission is designed to study for the first time the deep interior of Mars.
MarCO CubeSats follow InSight on his cruise to Mars. If they reach Mars, they will radio the data about InSight as it enters the atmosphere of Mars and descends to the surface of the planet.

NASA states in a statement:
A wide-angle camera above MarCO-B produces the image as a test of the exposure parameters. The MarCO mission, led by NASA's Jet Propulsion Laboratory in Pasadena, California, hopes to produce more images as CubeSats approach Mars by November 26. It is at this point that they will demonstrate their communication capabilities as NASA's InSight probe attempts to land on the red planet. . (The InSight mission will not use them, NASA's orbiters will retransmit the spacecraft data to Earth.)
This image was taken at a distance of about 12.8 million kilometers from Mars. MarCOs "chase" Mars, which is a moving target as it turns around the sun. To be in place during the landing of InSight, the CubeSats have to travel about 85 million kilometers. They have already traveled 399 million kilometers.
The MarCO-B wide angle camera looks directly from the CubeSat bridge. Elements related to the high gain antenna of the spacecraft are visible on each side of the image. Mars appears as a small red dot to the right of the image.
To capture the image, the MarCO team had to program the CubeSat to rotate it in space so that the bridge of its square "body" would be directed to Mars. After several test images, they were delighted to see this bright red sting.
Cody Colley, Head of MarCO Mission at JPL, explains:
We wait six months before we go to Mars. The cruising phase of the mission is always difficult, so you take all the little victories when they show up. Seeing the planet is definitely a big win for the team.

The recent photo of Mars is not the only "1st" for Wall-E and EVE. The distant Wall-E image of the Earth and the Moon – acquired May 9, 2018 – just days after the launch of CubeSat on Mars. Read more. Image via NASA JPL.
Final result: NASA's MarCO mission, consisting of two CubeSats the size of a briefcase and heading for Mars, aims Mars!
