A fantastic view of the surface of Mars

Here’s a stunning ten-minute video of the surface of Mars composed of a series of images strung together (up to a thousand in one panorama), with the photos coming from three different rovers. The large panoramas are then scanned with a video camera, a technique made famous by Ken Burns in his documentaries. I don’t […]

Mars Rover starts its mission today (launch 7:50 a.m. EDT); watch launch now

Reader Jon Mummaw alerted me, and I’m alerting you, that the new Mars rover is being launched today. In fact, in about 20 minutes from when this post goes up, the rocket will take off.  You can watch it live at the links below. Perseverance will not only collect soil samples from the bed of […]

SpaceX Demo-2 mission scrubbed

Bad weather has forced the postponement of today’s manned SpaceX mission until Saturday. The scheduled launch then is at 3:22 Eastern Daylight Time. Presumably the links that I put up this morning will still work then.  

Watch SpaceX’s Demo-2 launch live (if it isn’t scrubbed)

As you surely know, SpaceX is about to launch two “mature” astronauts up to the International Space Station today. The launch was set for earlier this morning, but apparently has been delayed. It’s still a “go” at this writing, though, with the liftoff scheduled for later this afternoon. The NASA broadcast begins in about an […]

SpaceX launch today at 10 a.m. EST (coverage starts at 9:40)

Reader Jon called my attention to a SpaceX launch today at 10 a.m. EST (it was originally scheduled for 9 a.m.), or exactly one two hours after this post goes up at 7 a.m. Chicago time. I’ll let Jon give the details and sites where you can watch it (his words are indented): Today SpaceX […]

Live feed of first all-women spacewalk

Here’s a live feed of the two astronauts working outside the ISS. As the YouTube video notes: On Friday, Oct. 18 starting at about 7:50 a.m. EDT, NASA astronauts Christina Koch and Jessica Meir will venture outside the International Space Station for a spacewalk. The duo will exit the station’s Quest airlock in their U.S. […]

How do astronauts do hygiene?

This new video, narrated by former NASA astronaut (and Columbia professor) Mike Massimino, answers a lot of your pressing questions about how astronauts keep clean in space. His answers apply to the Space Shuttle and to the International Space Station, though procedures sometimes differ between them.  Here are some of the important issues addressed in […]

Hurricane Dorian from space

Here’s an almost real-time view of Hurricane Dorian (just an hour from before I posted this) from the International Space Station. The storm, now a Category 5, is battering the hell out of the Bahamas. It looks peaceful from up there, but on the ground the winds are fierce. Here’s part of the YouTube summary […]

Dec. 24: Earthrise: First seen from space 50 years ago today.

Reader Jon sent me the link to this NASA video of “Earthrise”, first seen on this day in 1968. I’ll just put up Jon’s comment and the reconstructed video, based on both photos and analyses of where the spacecraft was when Earthrise was seen. In fact, I’m posting this at the exact time when Earthrise […]

Three minutes until launch of Space-X’s CRS-16

This rocket will resupply the International Space Station. Watch NOW! If you missed the launch (successful so far), the booster is going to do the patented Space-X vertical recovery at Cape Canaveral. SpaceX is targeting Wednesday, December 5 for the launch of its sixteenth Commercial Resupply Services mission (CRS-16) to the International Space Station. Liftoff […]
