CubeSat friends, like those sent to Mars InSight, can be used in future missions • Register


Portfell-shaped birds returned Marsian's tactile data

Vid Mars shooting spacecraft is nervous and slippery because you can think better. Nevertheless, NASA managed to control the entire process of InSight spacecraft thanks to its two-dimensional CubeSats portfolio.

After two key characters in this popular Pixar film, smaller satellites WALL-E and EVE were launched in May 2018 by a rocket carrying the main Marsian probe and split over the surface of the Red Planet. The CubeSat mission, which is called MarCO, is designed to detect the ability of small birds to survive a few million-kilometer safer journey, and may be helpful in reducing the data and images captured. For a project overview, see:

The rectangular CubeSats weighing up to 3.6 kg is the first to explore the planet other than Earth. After the rocket launch, they started out on the Red Planet to another trajectory than Insight and placed radio antennas and solar panels to get started.

NASA's Mars InSight Test really has Mars: it takes the first picture after it's taken


Their goal is to come back to the crucial information about the status of InSight Lander, who tried to climb to Marcian's face. During the installation phase, InSight released its updates via ultra-high frequency (UHF) radio waves. The Mars Reconnaissance Orbiter (MRO), which connects the dusty world of NASA, can select these signals, but will not be able to repeat the Earth over and over again, depending on the situation on the planet. A foreign body may be on the road or the Earth may not be the perfect place.

Although the orbit is a pure shooting ground, MRO does not accept data from Insight at the same time and can not send it to our home. In general, NASA surface surveillance has to sit for more than an hour after receiving the data to find out whether the MRO index really landed.

However, WALL-E and EVE have reduced the time to eight minutes and acted as a relay: UHF received telemetry and wound it to the Earth on the X-Band radio. They also had the right to get a clear line on the Earth. Their bandball band X band can replace 8 kilobytes per second.

"WALL-E and EVE we did as we were expecting," said Andy Cluch, Chief Engineer Mark Mission. "They have been tested to serve as a tag algorithm for future missions that CubeSats will give feedback to engineers in minutes."

This Monday, when NASA invaded InSight Red Planet on Monday, EVE pulled this picture of the rocky globe away from 7,700 kilometers.

NASA's short-term commitment and Marco's success enable CubeSats to act as a means of surveillance and space exploration. ®
