Artemis 2 Launch - Going Back to the Moon

[ISUTex]

Some of y'all never took Aero 351 "Astrodynamics" and it shows.

Orbital mechanics, conic sections, the math, ellipses, parabola, changes in energy and speed based on velocity and distance... its so beautifully, elegantly, brilliantly simple. I love it, its incredible to me.

If you want to geek out about it, investigate the equations and derivations to see how it works. It's just so damn simple.

One question. Do they have a space "poop shoot" that ejects waste into space or does somebody have a crappy job when they clean out the space pod back on Earth?

Is this covered in the book?

doesn't check out?

Yeah, you have a good point there!

Liquid waste gets ejected. Solid gets bagged and brought back

Enjoyed taking Aero 351 with Dr. Tannehil circa 1990.

Early 2000s for me. Chimenti for Astrodynamics. Unger for Aerodynamics. Tannehill was around but I don't think I ever had him.

 

[clone52]

LOL. Tannehill.

The only guys still teaching that I had are Vinay Dayal and PJ Sherman (not to be confused with PJ Hermann, who I also had).

Hell, one of my classmates (a year or two behind) is a prof there now.

I had Dayal for something, maybe structures. Was Sherman the one who owned a bar?

Petey Sherman? F that guy, he "taught" me engineering statistics.

And yes, he owned Boudelaire.

I remember a study session before finals there.

Were you watching the NASA feed? It seemed like they were very clear about the things that had never been done before and the things that haven't been done in over 50 years.

No only the national news, which was making it sound like this was the first time its ever happened. Outside of being further away and having four in the space craft what have we done this time that we had never done before?

Of course if the moon landings 50 years ago was all fake, then this would be the first time for everything. Just joking here.

My understanding is the Apollo was to close to the moon to see the poles of the moon.

 

[tman24]

Artemis was approximately 6500km from the moon at its closest and Apollo was 250km. Quite the difference.

Artemis was approximately 6500km from the moon at its closest and Apollo was 250km. Quite the difference.

That is because all of the Apollo moon missions entered the moon's orbit and circled the moon except Apollo 13 which used the moon's gravity to sling shot back towards earth. Since all the others actually went into orbit and circled the moon multiple times they would have to be closer to achieve that. This time it was nothing but a fly by of the moon, they only circled it once and never entered the orbit of the moon.

First time viewing a solar eclipse from lunar orbit.

There were plenty of firsts on this mission.

I so admire smart people. Lol.

we appreciate hearing that

I can't find these on the NASA website. I don't think they're real.

Unless it's from an actual NASA source, I just consider it AI.

Well, poop. I'll delete. And blocked the source.

Going to delete link in your reply so I don't end up misleading people. Thanks!

I hate when I get sucked into an AI post. I always block pages that post AI images of things that we already have authentic images of. If anything, mostly for them just being lazy asses.

I hate that I looked at pictures yesterday and had to look at the source to make sure it was real.

Crazy that they still aren't quite half way back yet.

Artemis II Flight Day 9: Crew Prepares to Come Home - NASA

On their last full day in space, the Artemis II crew began the morning with “Lonesome Drifter” by Charley Crockett as they approached Earth at 147,337 miles.
