Photonics Focus Magazine Vol. 3 Issue 3

May/June 2022 | Vol. 3 | Issue 3
Space-Based Astronomy

In this issue of Photonics Focus, we look at space-based astronomy missions, from short-term cubesats—which can be designed, built, and launched within a couple of years—to the GRACE satellite series, which has allowed astronomers to observe surface mass changes to Earth’s polar ice and water for decades. The longest-term mission described is STROBE-X, an X-ray astronomy mission that is at the same stage of development as the James Webb Space Telescope was in 1996.
