One of NASA's twin MarCO spacecraft – MarCO-B, aka Wall-E – captured this image on October 2, 2018. It was the first time this kind of low-cost, briefcase-sized spacecraft, called a CubeSat, has imaged Mars. See an annotated image below. Image via NASA / JPL-Caltech.
When you're only going to the CubeSats, it's easy to rack up a whole series of firsts. This week (October 22, 2018), NASA released the first-ever CubeSat image of the Red Planet's MarCO mission, now en route to Mars, due to arrive in November. Sure, the image is not very dramatic, but is not the task for hand for MarCO-A and MarCO-B, which were nicknamed EVE and Wall-E by NASA's Jet Propulsion Laboratory. Instead, the MarCOs – on on on May May 5 5 5 5 5 along along along along along along along along along along along along along along along C
InSight will touch down on March next month. That more elaborate mission is designed to study Mars' deep interior for the first time.
The MarCO CubeSats are following along behind InSight during its March. If they make it all the way to Mars, they'll be back in the news about InSight while it enters Mars' atmosphere and descends to the planet's surface.

NASA said in a statement:
A wide-angle camera on the top of MarCO-B produced the image as a test of exposure settings. The MarCO mission, led by NASA's Jet Propulsion Laboratory in Pasadena, California, hopes to produce more images to the CubeSats approach March ahead of November 26. That's when they'll be able to demonstrate their communications capabilities while NASA's InSight spacecraft . (The InSight mission will not rely on them, however; NASA's Mars orbiters will be relaying the spacecraft's data back to Earth.)
This image was taken from a distance of roughly 8 million miles (12.8 million km) from Mars. The MarCOs are 'chasing' Mars, which is a moving target as it orbits the sun. In order to be in place for InSight's landing, the CubeSats have about 53 million miles (85 million km). They have already traveled 248 million miles (399 million km).
MarCO-B's wide-angle camera looks straight out of the deck of the CubeSat. Parts related to the spacecraft's high-gain antenna are visible on either side of the image. Mars appears as a small red dot at the right of the image.
To take the picture, the MarCO team had to program the CubeSat to rotate in space so that the deck of its boxy 'body' was pointing at Mars. After several test images, they were excited to see that clear, red pinprick.
Cody Colley, MarCO 's mission manager at JPL, explained:
We've been waiting six months to get to Mars. The cruise phase of the mission is always difficult, so you take the small wins when they come. Finally see the planet is definitely a big win for the team.

The recent Mars is not only "1st" for Wall-E and EVE. Here's Wall-E's distant image of the earth and moon – acquired May 9, 2018 – just a few days after the CubeSat's launch to Mars. Read more. Image via NASA JPL.
Bottom line: NASA's MarCO mission – consisting of two briefcase-sized CubeSats on their way to Mars – have Mars in their sights!
