CubeSat friends can be used in future tasks, such as those sent to track the Mars InSight landing.

vid The landing of a spacecraft on Mars is frustrating and prone to failure. But fear, NASA, CubeSats, two briefcases, was able to monitor the entire process of the InSight spacecraft.

After two main characters in this popular Pixar movie, the small satellites named WALL-E and EVE were launched by the same rocket carrying the main Mars probe in May 2018 and left before landing on the surface of the Red Planet. The CubeSat mission, called MarCO, aimed to determine whether small birds could be able to withstand millions of miles of journey and return data and images from the landing. See below for an overview of the project:

Rectangular cubes, each weighing about 3.6 kilograms, is the first of its kind to study a planet outside the Earth. After leaving the launch rocket, they launched a different orbit on the Red Planet, and placed radio antennas and solar panels to begin their work.

NASA's Mars investigation really sees InSight's Mars.


The intention was to return the InSight to the basic information about the landowner's situation, as in the attempt to capture the Mars surface. During the landing phase, InSight transmitted its updates using ultra-high frequency (UHF) radio waves. The Mars Exploration Trajectory (MRO) surrounding NASA's distant and unforgiving dust world can receive these signals, but because of its position around the planet, it cannot always repeat them back to Earth. The foreign body may be on its way or the Earth may not be an ideal point.

Even when there is a clear shot on the earth in orbit, MRO cannot take the Insight data on the surface at the same time and transmit it to our house. As a result, NASA's ground control would have to sit for over an hour after receiving the data to determine if the MRO was actually landing in InSight.

However, WALL-E and EVE reduced this time to just 8 minutes and acted as relays at the same time: gathering telemetry in the UHF and teleporting it back to Earth on the X-band radio. They are also positioned correctly to get a clear line to the Earth. The X band radios in the form of a softball can change up to 8 kilobytes per second.

EV WALL-E and EVE carried them out as we expected, ğ said Andy Klesh, chief engineer for the Marwo mission. Hizmet CubeSats was an excellent test of how it could serve as bir labels ere in future missions and gave the engineers minute feedback during a landing. “

On Monday this week, EVE recaptured NASA's InSight to the Red Planet, re-beaming this rocky sphere back at 4,700 miles (7,600 kilometers).

NASA believes that the short development time and success of MarCO paved the way for CubSats to serve as secondary tools to track the spacecraft and study the Solar System. ®
