Astronomers have measured the power of a jet streaming from a black hole.

The jet from Cygnus X-1 -- a black hole orbiting a massive blue star -- is 10,000 times as powerful as the whole Sun! (That's 10^37 ergs/sec.) And it's moving at 50% the speed of light.

Jets of energetic particles streaming away from the black hole Cygnus X-1 (at left in this artist’s rendering) bend in the stellar wind from the supergiant star paired in orbit with the black hole. Researchers used the extent of the bending to produce the first measurement of the power of a black hole’s jets. Image: ICRAR/Curtin University

A NASA-sponsored mural about our return to the moon. Has an off-round collage in the center featuring a suited astronaut, the SLS rocket assembly, a moonscape, a starfield, and some abstract patterns. The background is a colorful pattern made of somewhat irregular overlapping rectangles and trapezoids, done in perspective as if the viewer is looking down a square tunnel or into a box. There's a yellow-graded Orion module hanging at the upper left.

Will we live to see a laser sail sent off to Alpha Centauri?

Wow, they sewed the Apollo spacesuits with TREADLE SEWING MACHINES

MIT Press: The Bra-and-Girdle Maker That Fashioned the Impossible for NASA

"...Key to these demands were NASA’s painstaking engineering standards, which pushed the very limits of the equipment and seamstresses’ own techniques. The tolerances allowed — less than a 64th of an inch in only one direction from the seam — meant that yard after yard of fabric was sewn to an accuracy smaller than the sewing needle’s eye. To achieve such precision, many women used a modified treadle that, instead of starting and stopping a Singer sewing machine’s operation, fired one stitch per footfall through the multiple layers of a suit’s surface. ..."

Prediction.
A decade from now, low-Earth orbit will be inaccessible after Starlink (now bankrupt) precipitates a massive #Kessler catastrophe. Years/generations will pass before new launches to #space are possible.
No #Moon missions; no #Mars missions.
#Musk's name is cursed (even more...).

"...The U.S. Space Force has approved the launch of a SpaceX Falcon 9 rocket carrying the Starlink 17-27 mission to low-Earth orbit, Tuesday, April 14, 2026, between 7:00 p.m. – 11:00 p.m. PT from Space Launch Complex 4 East (SLC-4)....There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions...."

Hmm, this is kind of neat, all the assembly source code for Apollo 11!

Four still frames from video from the pickup ship, one showing ocean and a radar bulb, one showing two helicopers on a pad atop the ship, one showing a big interior hanger area with some sort of yellow scaffolding in front, and one showing a large mechanical deployment arm and two runabouts with inflatable-style edges and seating for several people on each.

picture from artemis 2's exterior camera - the closer it gets to earth the more it looks like actually quite good sfx? which is hilarious because it's real

A look at Earth, a nearly half-full crescent, from one of Artemis's exterior cameras, with Artemis 2 also partially visible in the frame, most particularly part of the thruster pack, along with some exterior sensors and antennae

oo, they backed the camera out some more

#artemis #artemis2 #moon #space

Alt...

Artemis 2 exterior camera aimed at earth, like in previous photo, but zoomed back a bit with more ship visible. The entire primary thruster assembly is now in frame, as are various additional exterior instruments, antennas, sensors, and side thrusters, all against a deep black background of spaaaaaace.

Shot from the Artemis's outboard camera, the ship on the left, a section with side instruments mostly visible and the bottom of the N and A from NASA just peeking up from the bottom, upside down. Beyond the ship, the earth, half lit, the light side up in the photo, lots of clouds and land and ocean. You know, the Earth.

I really hope we see continued support for #NASAArtemis. Going to the moon felt like a much needed gift of joy to the world this week. Thank you #AstroVicGlover #astro_reid #Astro_Christina #Astro_Jeremy.

I missed that intentionally, but I now see that I really missed the opportunity to LMAO online. Though this of course is a much better take that anything I'd have to offer.

Those lovely spacesailors proved once again what has been obvious from the first day: they are exceptional people, in all aspects.

"During the lunar flyby, the closest Orion will come to the surface of the moon is 4,070 miles [6,550 kilometers]. From that distance, the crew will have a unique vantage point of the moon as a full disc — and the ability to take observations never before seen by human eyes."

Current status as per https://artemis.cdnspace.ca:

Lunar flyby — photography & observations

Duration: 6 hours
Progress: 22%

"Orion is carrying 32 cameras and devices [...] Fifteen cameras are mounted directly to the spacecraft, and 17 are handheld cameras operated by the crew."*

Looking forward to browsing https://www.nasa.gov/artemis-ii-multimedia/ when the photos are ready.

A space photo of our planet rising from behind the moon, which is closer in the view, taking up the bottom third of the image. The surface of the moon has a brownish tint, and is littered with shallow craters. Earth is further back in the view, backlit by the sun, which itself is not visible. Both our planet and the moon are surrounded by the darkness of space, but the image conveys solemn and introspective feelings of seeing our home from an unfamiliar angle, photographed by brave members of the moon mission crew.
