The low Earth orbit (LEO) has become a space junkyard.
This young team of researchers not only managed to send their satellite into space in
, piggybacking on Elon Musk’s SpaceX rocket, but they believe, based on a new analysis of data from Air Force Space Command, that their satellite could be part of an effort to reduce space debris in orbit.We can’t see it through the naked eye, but there arefloating around in low Earth orbit alone. There are millions of small and large pieces of space junk flying at the speed of 18,000 miles per hour, seven times faster than a bullet.
Built on a budget of $10,000, SBUDNIK, a bread loaf-sized cube satellite, was made using off-the-shelf products like AA batteries and $20 microprocessors. The students at Brown added a 3D-printed drag sail, made from Kapton polyimide film, which popped open like an umbrella up in space and is recording photos of Earth and sending back temperature data.
Rick Fleeter, an adjunct associate professor of engineering at Brown, said, “The large complex space missions we hear about in the news are amazing and inspiring, but they also send a message that space is only for those types of specialized initiatives. Here, we’re opening up that possibility to more people. We’re not breaking down all the barriers, but you have to start somewhere.”
The project is a result of a collaboration between researchers at Brown’s School of Engineering and the National Research Council of Italy. It is also supported by D-Orbit, AMSAT-Italy, La Sapienza-University of Rome, and the NASA Rhode Island Space Grant.
