NASA is one of the efficient and biggest Aerospace companies in the world, and it always does something which keeps us amazed and a new secret is revealed about the universe. When the NASA launches InSight lander to Mars, then two MarCO probes were also launched into space which was of great use and now it seems that they have gone silent and they are not able to track them. Two probes named EVE and WALL-E, the names are inspired by the Pixar movie.
MarCO probes were generally modified CubeSats which were so small of the size of the cereal box and were of the great significance of space research. These two satellites worked greater than the expectations and covered the landing of InSight lander accurately on Mars. Because of those steps, scientists were able to track the activities of the InSight lander.
Joel Krajewski who is the project manager of the MarCO spacecraft said, “We got the data much earlier than we would have — in near real-time as the landing was happening — adding to the excitement of the event.” Those probes gave real-time notifications to the engineers to ensure a safe landing. Other probes like NASA’s Mars Reconnaissance Orbiter are also there but was the problem of location as it observed the InSight but then dipped into the horizon.
If something had gone wrong during InSight’s landing, it might have taken some time for NASA to diagnose and work the problem without the MarCO satellites. “We always want to get data from a landing while it’s happening, in case the unfortunate happens and we lose a lander,” Krajewski says. “We want the equivalent of the airline black box to understand as much as possible.” InSight Lander successfully landed, and MarCO also sent pictures of the landing. But now it seems to go silent, and it is believed that they have gone into deep-space and it is good news for NASA scientists.
