After crisis in interstellar space, stream of Voyager 1 data resumes. Before its computer crashed, the venerable NASA probe may have entered mysterious new region beyond the Solar System.
This ensures that more big, bright #satellites are coming: "A Block 1 satellite would have 10 times the capacity of the company’s 1,500-kilogram BlueWalker-3 prototype; [Block2] would be twice as big and have 10 times the capacity of a Block 1 BlueBird." (via @spacenews_inc)
(Also, a reminder that this comms mode is potentially very harmful to ground-based radio astronomy.)
You first go slow - less than 100m/s (360kph, or 220mph) for the first stage, up to around 30-40km. This gets you above the thickest atmosphere. Then the second stage can take over with an engine more optimized for vacuum.
#PPOD: Korolev is an ice-filled impact crater in the Mare Boreum quadrangle of Mars, located at 73° north latitude and 165° east longitude. The crater is 81.4 kilometers in diameter and contains about 2,200 cubic kilometers of water ice, comparable in volume to Great Bear Lake in northern Canada.

New, on @TheConversationUS:
I'm an Astrophysicist mapping the Universe with data from #ChandraXRay: Clear, sharp photos help me study energetic black holes.
If you’ve been looking at everything NASA is doing and wondering “ok but when are we ACTUALLY going back to the moon, and what’s the plan here?” this video is for you.
Here’s a rough timeline of the Artemis program, along with context:
The current launch date of June 1 seems to be holding. The NASA/Boeing/ULA team will hold a flight readiness review today to ensure that the spacecraft and launch vehicle are ready, and there will likely be a media telecon tomorrow.
"A bit of me feels that the horse has bolted and we're in catch-up mode at this point."
But: "There's a social good element to what the satellite operators are doing and you've got to balance that against possible impacts to things like radio astronomy."
This image shows the regions surrounding the Corona star cluster, better known by its English name, Coronet Cluster. Also cataloged as R CrA for its brightest star, it is located at a distance of about 400 light years from the Solar System and is located in the direction of the Corona Australis Constellation, isolated on the edge of the Gould Belt. The Corona Cluster is..... #astronomy#space#astrophysics#astrophotography
My Harvard Horizons video is now on YouTube! I worked hard on this with some talented animators, really excited to share it with ya'll :)
