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 […]

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 […]

It’s time to watch the Mars landing!

It’s time to watch the InSight probe land–NOW!  A live video from NASA is below. Seven minutes until separation. and about 22 minutes till touchdown! Remember that it takes light (and radio signals) three minutes to get from Mars to Earth, so we won’t know whether the landing is successful until 182 seconds after it […]

Mars InSight probe lands today

Reader Jon kindly reminded me this morning (after letting me know last week) that NASA’s InSight “stationary lander”,  launched from Earth on May 5, will—if all goes well—touch down today at about 20:00 UTC (3 p.m. Eastern time in the U.S.). The distance of the journey: over 301 million miles! The lander is basically a probe that […]

Apollo 11 lift-off

Here’s a high-speed film the Apollo 11 rocket, the Saturn 5, taking off on its way to the Moon on July 16, 1969.  We see 30 seconds of actual time, but it’s slowed down to last nearly 9 minutes by the filming, done at 500 frames per second. The lunar module landed on in the […]

Astronaut Alan Bean confronts a Moon-landing denialist

Astronaut Alan Bean (born 1932), the fourth person to walk on the Moon, died yesterday at age 86. His moonwalk was in 1969, and, after participating in the Skylab program, he retired in 1975 to devote himself to painting. Here’s a photo of him on the Moon during the Apollo 12 mission: Bart Sibrel is […]
