Interesting Things with JC #845: "Deep Space Optical Communications" - NASA's DSOC, a marvel in space innovation, achieves "first light," beaming a near-infrared laser with test data 10 million miles to the Hale Telescope. This milestone, aboard the Psyche spacecraft en route to the asteroid belt, paves the way for high-data-rate communications supporting humanity's dream of reaching Mars.
