Space Is Very Big. Some Of Its New Explorers Will Be Tiny
Last year, two satellites the size of cereal boxes sped toward Mars as though they were on an invisible track in space. The satellites, known as cubesats, were sent to watch over NASA’s larger InSight spacecraft as it attempted a perilous landing on the surface of Mars at the end of November. The operation was a success, and the performance of the MarCO satellites may change the way missions operate, enabling cubesats to become deep space travelers in their own right.
