You don’t need a big satellite to do big science. Smaller satellites can cost less to make. So even small research teams can rather inexpensively rocket their instruments into orbit. One group has just launched tiny telescopes this way to study stars.
The Hubble Space Telescope may be the most well-known instrument orbiting Earth today. It is also huge. At 13.2 meters long, it’s about the length of a school bus. And at more than 11 metric tons, it weighs about 50 percent more than an elep...
