NASA is one of the biggest and successful Aerospace Research Company. It has delivered many successful projects and dug out many facts about the universe and alien life. Last year when NASA launched two little satellites just for the purpose to know more facts about space, but now it seems that NASA has lost contact with them. But interestingly this is not a piece of bad news for NASA as they are expecting them to go and explore other worlds which exists in our solar system.
Those two tiny satellites named EVE and WALL-E were launched into space with InSight lander last year. The science fiction movie named Pixar inspires these names. These are called as Marco probes as they are modified CubeSats, small in size typically equal to the cereal box size. These CubeSats only orbited the Earth, but then they are changed into Marco and can be used to send them to study deeper space.
They were launched with the InSight lander when it was going to Mars on May 5th. These small satellites sent the information to the earth when InSight lander was landing on the Martian surface. They were posting real-time images also and covered the whole landing sequence. Joel Krajewski who is the project manager of MarCO mission 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”.
MarCO satellites were so useful for the NASA during the landing of InSight as they were giving the real-time updates so if there would be any wrong during the event, then the engineers and scientists could immediately work on that and ensure a safe landing. There are other probes also which are roaming in the Mars orbit, but they are not of much use as they were, because of their different positions. NASA’s Mars Reconnaissance Orbiter also observed the landing, but it dipped below the horizon and scientists have to wait for three hours after that.
“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.” “This mission was experimental from day one, where much of the objective of MarCO was simply to survive as we traveled out to Mars,” Andy Klesh, the MarCO chief engineer at NASA JPL, tells The Verge, adding that, “two months into the mission, we had proven every piece of our technology.” But the team is not sure about the reason why these MarCO have disappeared; they are saying that it might be possible that they went into the deeper space.
