DYK the Nancy Grace Roman Space Telescope got an unexpected boost in 2012, when @NRO_gov gifted NASA two unused spy telescope mirrors? One of these mirrors was repurposed for Roman, enabling a wider field of view for its exploration of dark energy, exoplanets, and astrophysics.

One giant leap for mankind History was made on July 20, 1969, when Apollo 11's Neil Armstrong and Buzz Aldrin became the first to set foot on the Moon. For more than 5 decades, the total number of moonwalkers has remained at 12. NASA will change that with Artemis IV. https://t
