New nanoparticle sets record for fastest rotating object...300 billion rpm!  https://techxplore.com/news/2020-01-nanoparticle-levitated-rotates-billion-rpm.html?fbclid=IwAR1BRyk99is4rOI1O0URXdorETquuzCk0xlI_ikc9N65kf7KTriBbdTRBrs

I'm just imagine the nerd sitting there counting that... 1, 2,3,4,5...dammit...1,2,3...

 

[msommer]

Also not really in the physics or astronomy fields but Crew Dragon tested today against catastrophic launch failure

Pretty cool

Thought I mentioned it previously...saw an old HS friend recently who is a union cameraman for tv and mostly film. Worked on Ford vs Ferrari recently. He's been doing a bunch of work for nasa lately shooting ultra hi def film of Boeing and Musk tests (both run everything they do through NASA). Showed me some screen shots he snapped...insane.

What were you seeing?  Do you even know?  Bound to secrecy?

Saw a story (no link) that Space X astronats will drive up in a Tesla instead of the “astro van”.

Close-ups of rockets in various stages of testing...coolest was the most recent parachute test. And boobs

I must admit I'm slightly surprised NASA is taking HD pictures of boobs, but I won't ask...

You just don't understand it.  I mean, it's not rocket science.

 

[Cold Dead Hands]

You just don't understand it.  I mean, it's not rocket science.

If you say it is for rocket science they will give you HD pictures of boobs! Oh, and rockets.

Boobs!

man I’d love to work there.  Only about 5 miles away.

You'd love to work at a place that explodes and is currently on fire, because of the commute?
OK then....

That would be a great commute, though.

I believe the main office is in Cedar Park, about 25 miles from the test launch site in Briggs.

500,000 pieces of space junk orbiting the earth marble size or larger being tracked (at least that was the number back in 2013)

Yeah.  A couple chain reactions of satellites and a that's the end of space for the next thousand or so years.

Yup.  It says 1 in 1000 chance.  But they also said that's much greater than it sounds.

 

[El Floppo]

Considering "space", yeah...those sound like bad odds. Better than the 1:100 from earlier though

It now says 1:20.

Apparently they missed colliding by just a few feet.  Scary.

Read an article on Al Jazeera yesterday about Congress possibly shutting down/postponing the 2024 manned moon trip...I think over NASAs delay in detailing expenses (I scanned more than read the article).

Eta...China scheduled to go in 2025, Russia in 2030.

Did anybody watch that Apple TV show about the space race? This fits right into that.

Pretty sure we already won the Space Race 50 years ago.  Still waiting for the second place finisher to cross the line.

You should watch the show...alt-history where Russia got to the moon first. Very good watch.

This makes sense now.  I saw the previews for it and was thoroughly confused.

Pretty cool.  hard to make out what they are saying a lot of the time, so it is nice to have the transcript to read along with.

Serious?!?  I’m supposed to be in St Augustine that weekend, should be okay viewing similar my normal spot in Orlando.  Dang, I really wanted to actually go to KSC for this launch

Don't think they're letting anybody watch live other than invited press.

Although with the beaches opening, who knows

There's a KSC visitors center — may be opened back up by then.

There's a KSC visitors center — may be opened back up by then. 

Hope it works out...this is from one of the articles yesterday (CNN).

Because of Covid-19, however, there will be no crowds of spectators lining the beaches and viewing sites along Florida's Space Coast to watch the craft hurtle toward the ISS, as they have for the launch of nearly every crewed US mission since Alan Shepard became the first American to reach space in 1961.

Only a limited number of reporters will be allowed on site, and NASA said it will not host any members of the public.

Happy Birthday to the Hubble Space Telescope!!!   Launched 30 years ago today, April 24, 1990.

 I’ve tried to get into star gazing for a while now but never wanted to spend the money on decent equipment and I had little patience.

Decided to by myself a 6in dobsonian telescopes a few months ago.  I've had some great looks at the moon, but haven’t had a chance to see any planets and the deep space stuff seems over my head right now.

Anyways, I couldn’t sleep tonight so I checked outside and it was clear as could be.  I screwed up my red dot finder getting it set up and almost bagged the 2am expedition to the front yard.  Finally got it set and aimed it at Jupiter and HOLY #### I saw it as clear as could be.  Moons and all.  Same with Saturn.  This stuff was mind blowing.  I think I was out there for about 3 hours.   Was a little disappointed in Mars after seeing Jupiter and Saturn.

Red dust doesn't grab your interest?  Huh.
