Black holes seem to have a sweet spot in terms of size, power and lifespan which is almost ideal. A black hole weighing 606,000 metric tons (6.06 × 10 8 kg) would have a Schwarzschild radius of 0.9 attometers (0.9 × 10 –18 m, or 9 × 10 –19 m), a power output of 160 petawatts (160 × 10 15 W, or 1.6 × 10 17 W), and a 3.5-year lifespan ...
USA-165 or XSS-11 [2] (Experimental Satellite System-11) is a small, washing-machine-sized, low-cost spacecraft developed by the U.S. Air Force Research Laboratory's Space Vehicles Directorate to test technology for proximity operations. In particular, the satellite was designed to demonstrate "autonomous rendezvous and proximity maneuvers."

Blue Origin's famed New Shepard spacecraft successfully simulated the moon's low gravity on board its capsule during a brief flight Tuesday morning over West Texas.. Video of the uncrewed launch ...
Tau Zero, a hard science fiction novel by Poul Anderson, has a spaceship using a constant acceleration drive. Spacecraft in Joe Haldeman's 1974 novel The Forever War make extensive use of constant acceleration; they require elaborate safety equipment to keep their occupants alive at high acceleration (up to 25 g), and accelerate at 1 g even ...
Supermassive black holes sometimes shoot vast jets of high-energy particles into space, but no such jet has been detected in this instance, according to astrophysicist and study co-author Lorena ...
An X-37B onboard camera captures an image of Earth. Orbital Test Vehicle 7 (OTV-7), also referred to as United States Space Force-52 (USSF-52) or USA-349, [3] [4] is the fourth flight of the second Boeing X-37B, an American unmanned vertical-takeoff, horizontal-landing spaceplane.
