“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

— Douglas Adams, ‘The Hitchhiker’s Guide To The Galaxy

Chinese Rocket Hits the Moon

That mystery rocket debris floating around in space, which was once thought to be from Space-ex, it turns out was from China. It collided with the moon yesterday and left a crater up to 20m wide.

From The Verge story:

Originally, space trackers thought it was a leftover piece of a SpaceX Falcon 9 rocket that had launched a weather satellite back in 2015. But after careful analysis, various groups of space trackers confirmed that the rocket was likely leftover from the launch of China’s Chang’e 5-T1 mission — a flight that launched in 2014 to test out technology needed to bring samples back from the Moon. That mission, launched on a Chinese Long March 3C rocket, sent a spacecraft looping around the Moon in an attempt to see if China could send a vehicle to the Moon and then bring it back to Earth. Given the flight profile of the Chang’e 5-T1 mission and the tracking of the mystery object, astronomers are fairly certain that a chunk of the Long March 3C rocket has remained in an extremely elongated orbit around Earth ever since, only to find its way to the far side of the Moon.

The moon does a pretty good job of sweeping up space debris that’s way out there.

The New USA Space Force Logo

In December, the United States announced a new branch of the military, The Space Force. Today they released the logo for the new service and a lot of people are talking about how it looks like the logo from StarFleet.

I did a quick search and as much as it tickles my biases to make fun of the logo, it’s fair to say Star Trek copied real life space organizations rather than the other way around.

This collection of Star Trek logos shows that Trek did a bit of borrowing from NASA and the United Nations.

Man Will Spacewalk

Neil Armstrong and Moon Lander

With today being the 50th Anniversary of Neil Armstrong’s historic walk on the moon, I bring you this little classic reverse speech from the first words spoken on the surface of the moon which, when reversed, sound like “man will spacewalk”.

Forward:’a small step for a man’

Play in Reverse

Reverse: ‘Man will spacewalk.’

Also of interest, on this anniversary of scientific achievement, NASA has released a collection of 45 panoramic photos from the surface of the moon based on images stitched together from the various Apollo missions.
