My Balloon Got Away

NASA is preparing to send a new telescope, 24 miles up into the stratosphere. The Astrophysics Stratospheric Telescope for High Spectral Resolutions Observations, is called Asthros for short. The 8.4-foot telescope will be launched, on a balloon the size of a football stadium. Asthros will be able to observe far-infrared light, that’s invisible to humans.
