Nasa CubeSat beams back Mars image

Washington DC: NASA's first CubeSats to travel into deep space have beamed back an image of Mars -- visible as a tiny red dot against the dark sky.

The twin, low-cost MarCO CubeSats, which are sharing a ride with InSight Mars lander, were designed to find out if they could survive the journey to deep space.

The two CubeSats are officially called MarCO-A and MarCO-B. The image of Mars was taken on October 3 from a distance of roughly 12.8 million kilometres.

A wide-angle camera on 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 as the CubeSats approach Mars.

On November 26, they'll demonstrate their communications capabilities while NASA's InSight spacecraft attempts to land on the red planet.

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 to travel roughly 85 million kilometres. They have already travelled 399 million kilometres.

MarCO-B's wide-angle camera looks straight out from 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 in the image.
