Was going to post this also. Interesting how they split the code up.

Yeah those people are way too smart. Reminded me of some of the problem solving from The Martian.

They also look quite old... like these are the only FORTRAN people that are still working.

On the morning of June 3, eight planets line up. Uranus and Neptune are not visible to the naked eye but can probably be seen with binoculars.

NASA Boeing Starliner launch on hold at T-3:39. Launch just scrubbed. Ground launch sequencer error. Good news is the capsule hatch door seems very secure.

ETA: possibly only 24 hour delay.
ETA: may be a Wed or Thur.

Four volunteers who spent more than a year living in a 1,700-square-foot space created by NASA to simulate the environment on Mars have emerged.

The members of the Crew Health and Performance Exploration Analog mission — or CHAPEA — walked through the door of their habitat at NASA’s Johnson Space Center in Houston on Saturday to a round of applause.

"
Hello. It’s actually just so wonderful to be able to say hello to you all,” CHAPEA commander Kelly Haston said to the assembled crowd.

Haston and the other three crew members — Anca Selariu, Ross Brockwell and Nathan Jones — entered the 3D-printed Mars replica on June 25, 2023, as part of a NASA experiment to observe how humans would fare living on the Red Planet.

The volunteers grew their own vegetables, maintained equipment, participated in so-called Marswalks and faced stressors that actual space travelers to Mars could experience, including 22-minute communication delays with Earth.

The 378-day endeavor was the first of three NASA missions the space agency has planned to test how humans would respond to the conditions and challenges of living on Mars, where it says it could send astronauts as soon as the 2030s. NASA’s second CHAPEA mission is scheduled for the spring of 2025, and the third is slated to begin in 2026.

After emerging from isolation on Saturday, CHAPEA science officer Anca Selariu reflected on why she and others chose to dedicate themselves to this particular effort.

“I’ve been asked many times: Why the obsession with Mars? Why go to Mars?” Selariu said. "Because it’s possible. Because space can unite and bring out the best in us. Because it’s one defining step that Earthlings will take to light the way into the next centuries.”

NASA has conducted other isolation experiments before, including simulated journeys through space of roughly 30 days and underwater missions lasting up to three weeks at a time.
 
Two different meteor showers are happening tonight.

The Southern Delta Aquariids will be most active Monday night through early Tuesday and could ring in a viewing of up to 25 meteors per hour depending on your location, according to the American Meteor Society. And on Tuesday night, the minor shower Alpha Capricornids — known for its bright fireballs — could also bring five meteors per hour to the celestial party.

Ok this isn't a physics or astronomy thing exactly, but figure this is the right audience for it.

If you haven't read the book Project Hail Mary by Andy Weir, let me recommend it to you. He's the guy who wrote The Martian which was made into the Matt Damon movie. And if you like the sense of humor Damon's character has, that's all from the author and the same sense of humor is present in Project Hail Mary.

It helps to be into science a bit as he does some physics at points along the way to figure things out. But the book is enjoyable even without that. Anyway, it's a true treasure in my mind, probably my 2nd favorite book ever, so was looking for the right audience to pass it along to.

Great book
 
Looks promising for aurora further south again tonight.

I think I’m too close to the city, as could not get anything even with the extended time lapse on my DSLR. Will try again tonight though.

Earth will capture 'second moon' this weekend, scientists say

Earth will get a "second moon" this weekend, but it won't be sticking around for long.
www.space.com www.space.com

NASA scientists have calculated that Earth will capture a "second moon" on Sunday (Sept. 29). The "mini-moon" comes in the form of the tiny asteroid 2024 PT5, which usually orbits the sun as part of a small asteroid belt that follows Earth.



According to the latest data available from NASA's Jet Propulsion Laboratory Horizons system, the temporary capture will start at 15:54 EDT (1954 UTC) and will end at 11:43 EDT (1543 UTC) on November 25



mini-moon event expert and Universidad Complutense de Madrid professor Carlos de la Fuente Marcos told Space.com on Wednesday (Sept. 25).



The object that is going to pay us a visit belongs to the Arjuna asteroid belt, a secondary asteroid belt made of space rocks that follow orbits very similar to that of Earth at an average distance to the sun of about 93 million miles (150 million kilometers)," Marcos told Space.com last week. "Objects in the Arjuna asteroid belt are part of the near-Earth object population of asteroids and comets."



Though the idea of Earth getting a second moon sounds extraordinary, these gravitational capture events are actually quite common.
