NASA has successfully tested they were launched to monitor the NASA InSight mission
The fashion for tiny satellites with the ability to perform one or a couple of tasks is growing every year. Previously, such satellites were withdrawn more than once and performed the task in the orbit of the Earth disappeared without a trace, while the cost of carrying out a measurement repeatedly decreased. Now everything is a bit more complicated with sebastani, they have gone even to other planets. In the mission to Mars, which was attended by a probe with a landing platform NASA InSight also accompanied by two not large satellites that transmitted to Earth telemetry of the object and by what was received from them, scientists already know that the landing occurred and it is successful.
The American probe successfully landed on the surface of Mars on November 26, 2018, for mini satellites this date is almost akin to death, they have the end of their mission.
Cost this mission of two satellites is not large developers in $18.5 million Mission called Mars Cube One. This is just a demonstration of technology and nothing more, in fact, this program did not carry a special semantic load, but in view of the fact that it was successful, it is discussed very briskly. Mini satellites weighed only a little more than 13 kg each, but at the same time they could monitor the surrounding world and even report useful information to the remote control. Developers probably in the seventh heaven that mini satellites flew such an impressive distance and at the same time worked at 100% successfully.
Small satellites called WALL-E and EVE. If anyone has seen a cartoon with similar characters, just in their honor and named these two devices. The cartoon is called Pixar "WALL-E". Something similar couple also carried out in space, having tried to dance with a fire extinguisher. In order to maneuver in a vacuum need to emit gas under high pressure to control such small devices need very little gas, and it is convenient and economical. These two small escort satellites were made according to the same Assembly scheme, but they did not behave exactly the same in outer space. One satellite behaved perfectly and it was not difficult to control, but the other on the contrary it was difficult to catch and just as difficult to tell him something, in the end, a micro satellite called WALL-E was in fact just fidget.
Micro satellites though flew to Mars, but on the surface of the planet they did not get, and the orbit of the red planet, they also are not destined to get, as gas reserves for maneuvering is not sufficient. As a result, both micro satellites flew past at a distance of 4 thousand km from the surface of the planet. The satellites are still transmitted to Earth meter landing of the descent module of NASA InSight that was the culmination of the program, Marco. Next, the satellites will continue their flight and will fly around the Sun on its special trajectory. At some stage of its flight satellites may again be caught in the radio capture and provide them to the next round of some new task.
