The National Reconnaissance Office just revealed the existence of its "JUMPSEAT" line of spy satellites, eight of which launched to Earth orbit between 1971 and 1987.
Despite the US administration's threats to cancel the nearly complete Nancy Grace Roman Telescope, it's on track to launch this year or next. When it's launched and sent toward its orbit at the Sun-Earth L2 point, it'll carry two instruments and be ready to tackle three new astronomical surveys. One of them is the Galactic Bulge Time-Domain Survey (GBTDS).
