" "The ’s first image looked like all hell. A month later, in late June 1990, the telescope's political shepherd, , found out what had gone wrong. He called some interested local astronomers—, Don Schneider, and particularly —and since astronomy in Princeton, New Jersey, usually involves food, he invited them to supper at a Route 206 strip-mall Chinese diner. He told them that NASA was about to announce that the telescope's perfect mirror had been ground to the perfectly wrong shape. Jim Gunn, who had designed and overseen the construction of the telescope's principal camera, had also seen the first image and had thought the problem might be fixed. But no, now Bahcall was telling him no, it was the mirror's shape, the telescope couldn't focus, the problem was irrevocable.
…
NASA, of course, pulled off an ingenious fix, installed by astronauts dangling improbably over the telescope up in space.

Following the launch of NASA's planet-finding in 2009, the number of possible s quickly multiplied into the thousands — enough to give astronomers their first meaningful statistics on other planetary systems, and to undermine the standard theory for good. Not only were there lots of exoplanet systems bearing no resemblance to ours, but the most commonly observed type of planet — a 'super-Earth' that falls between the sizes of our world and Neptune, which is four times bigger — does not even exist in our Solar System. Using our planetary family as a model, says astronomer of the , “has led to no success in extrapolating what's out there”.
... Defense physics is generally ; it solves problems by applying other physicists' more basic work. Its result is usually not knowledge but technology. The adjective applied, when used by physicists, is not a compliment. Academic physics is pure research; its direction is determined by what academics are curious about and can get funding for. It is, of all the sciences, the most fundamental; its questions are about matter's basic nature and the forces that govern the known universe. Moreover, pure research is considered innocent, neither moral nor immoral. Applied research, whose technologies have potential for harm, comes accompanied by difficult moral decisions.
The fundamental necessity of space security is knowing where every satellite is and how it is behaving. ’s June 2020 doctrine calls this “space domain awareness.” Officially that awareness comes via a global network of sensors on satellites and telescopes on the ground that covers all orbits all the time and tracks everything bigger than 10 centimeters: 3,200 live satellites, as well as 24,000 nonfunctioning “zombies” and pieces of space debris that, in a collision with a satellite at 35,400 kilometers an hour, would cause a catastrophic breakup.
The information is sent to Space Force’s 18th Space Control Squadron at the Combined Space Operations Center at in California. Data on the secret satellites are set aside, and the rest go into a public, free, online catalog called Space-Track, from which “conjunction notifications” are issued when two satellites look like they might get too close.
