Do think all those Flat Earthers and those that wanted to deny that we went to the moon during the Apollo Program are having a hardtime right now.

Then wait a few years, if we do not destroy ourselves, when we have permanent bases on the moon. And then during the night when we look up at the moon, one would be able to see the lights from the bases on the moon being visible to all who will want to look. Maybe first with enhanced optical equipment, then as times pass, with the naked eye. Just like in space one can see our human cities all lit up with their lights.

Then on to Mars. And just maybe when the young people today are old they will be able to take vacations on the Moon or maybe even on Mars. And they will then look back in history to these first rocket trips under the Apollo and Artemis Programs, which humankind first went off of the Planet Earth to the Moon and beyond.

Read an article some years ago that predicted that in 200 years, (Or More), that more people would live off the Earth, then on the Earth. Will Add that is If we humans do Not destroy ourselves first. If we indeed do Not destroy ourselves and maintain our freedoms, what the young people today might witness and see in their lifetimes. And how in going into space could change things. For one in going into space do we see just how precious and wonderful our own Planet Earth is ... Such A Paradise! Just what the the future does promise in a positive positive way.

Just thought would mention this for whatever it might be worth.

I can’t see ever moving large numbers of people off planet for any reason, like preserving the species. A few, for manned industry, maybe. The freight is just too high.

It would have to be a basic premise that the cost would be no higher than moving people via airplanes. And how many hundreds of millions of people do that every year? A quick check says 3,000,000 every day in the U.S.

I've been following the mission using a NASA tracking website. This mission is so Woke that the graphic they use for the Earth doesn't show North America or even the Western Hemisphere. It instead shows Africa and the capsule splashing down off the west coast of Africa. The capsule is, in fact, splashing down off San Diego. How hard would it have been to find or create a freaking graphic to show North America? Maybe it's supposed to be a subtle cue about how we're all "out of Africa." If you recall, the 2009 movie "2012" had the ship grounding in Africa at the end of the movie (I don't recall but I wouldn't be surprised if it was at the same place in Africa where they found the little hominid "Lucy"), so maybe it's a common device now for The Woke as well.

Well isn’t that special? This, along with the theatrical movie poster above may as well be a DEI propaganda poster…looks like they e checked all of the boxes!

But.....

.....that doesn't include the freight on Oxygen and Water. Cuz like if you're going to live off world, you got to have it, to live off world. They don't grow on the moon and will need to be trucked in. While flying passengers around the world you don't. Just alcohol in small bottles, and working latrines.

And heaven forbid you get a squeamish woman with a snake. She'll suck out a half a days oxygen in a single breath before letting it out.

I heard on the radio that Atemis 2 is re-entering earth's atmosphere faster than any previous spacecraft.

Looked that up to confirm--and found the following:

The Artemis II spacecraft is returning at high speeds—approximately 25,000 mph (11 km/s)—because it is performing a direct return from the Moon, where Earth's gravity accelerates it significantly during the approach. This speed is necessary to complete the mission within its timeframe without requiring an impractical amount of fuel to slow down in deep space.

Why the High Re-entry Speed?
  • Gravitational Acceleration: As the Orion capsule falls back toward Earth from the Moon, it is accelerated by Earth's gravity, reaching extreme velocities upon hitting the upper atmosphere.
  • Fuel Efficiency: It is physically impractical to carry enough fuel to slow the spacecraft down significantly before reaching the atmosphere. Instead, the spacecraft uses the atmosphere itself as a brake.
  • Kinetic Energy: The spacecraft possesses massive kinetic energy that must be dissipated. Atmospheric drag converts this energy into heat, slowing the capsule from ~25,000 mph to roughly 17-20 mph for splashdown.

Comparison to Previous Missions
Artemis II is among the fastest human-rated re-entries in history, breaking records previously held by the Apollo 10 mission. While the entry speed is similar to Apollo, modern technology allows for better control. The Orion capsule uses a robust heat shield (AVCOAT) designed to withstand temperatures exceeding 3,000°C, ensuring the crew remains safe while the atmosphere absorbs the intense energy.

---------------

I'm rather concerned about this.

Hope all goes well.

--contrary to the (stupid) news radio report, though, the astronauts are NOT expected to pass out once they splash down--

Key Safety Factors:
  • Controlled Deceleration: The Orion capsule uses a series of parachutes to slow its speed from approximately 25,000 mph upon atmospheric entry to about 17–20 mph by the time it hits the Pacific Ocean.
  • G-Force Management: The crew is expected to experience approximately 3.9 Gs during re-entry. Astronauts are highly trained to withstand these loads, and experts have noted that such G-forces are well within the limits they train for.
  • Specialized Suits: The astronauts wear the Orion Crew Survival System (OCSS) suits, which include features designed to help maintain blood pressure and circulation, preventing the dizziness or fainting (orthostatic intolerance) that can occur when returning to gravity after time in space.
  • Steep Entry Angle: NASA modified the trajectory to a steeper angle to help manage the extreme heat and pressure on the heat shield, ensuring the craft remains stable throughout the descent.
The mission is designed for the astronauts to remain alert, as they may be required to participate in recovery operations or initial medical evaluations shortly after landing

After a journey of more than 690,000 miles, the crew is nearly home.

The Artemis II crew will splash down off the coast of San Diego later today and, though it won’t be visible from land, you can still wave in their general direction to welcome them back to Earth!

NASA’s Artemis II mission is set to return to Earth today, following their trip around the moon. According to the released timetable, the Orion crew module will separate from the service module and begin its descent around 7:30 p.m. ET, with the first set of parachutes expected to deploy around 8:00 p.m. ET, following their 3.9 G reentry into Earth’s atmosphere. Due to concerns over the Orion spacecraft’s heat shield, NASA plans to send the craft on a more direct reentry route to limit the time it is exposed to the extreme temperatures of reentry into Earth’s atmosphere.

Why?

I don't ask to be argumentative, I really want to know. Other than the predictable toilet issues, this mission has been smooth as silk, and the crew have done everything well. NASA is actually shining for the moment, so I don't get the bile.
Click to expand...
No bile. Just honestly worried about this due to the very real effects of DEI on complicated events. Look, back in the early days of space exploration, there were a few things that went horribly wrong. Gus Grissom and crew were killed in a test. Apollo 13 came close to losing it, but they were able to do "on the fly" what this current crew has done as a mission.

My point is people used to be hired on by merit alone in the business of space travel. I vividly remember Obama telling NASA that it needed to hire more moslems. This wasn't by what they knew, but what they were. What does their hiring practice look like now?

I have very little faith in the workings of complicated structures or ventures today because too many (one is too many) people are hired due to what they are as opposed to what they know.

In the beginning there were some errors, but that was because it had never been done before. People were capable. Yes, we lost two shuttles. Yes, others died in accidents. It was all new.

IMHO, too many people in the entire structure are there only because they fit a certain metric that has little to do with expertise. In a complicated set, that just increases the potential for catastrophic failure.
This doesn't even address the talent pool from which they can draw. Education has just about collapsed in the last 50 years. That's good for a thread of its own.

I'm actually praying that these people make it back alive.

Are you sure about that?
Groucho, I won't take your response point-to-point, but I will tell you that despite the DEI busybody horseshit, the NASA astronaut office has a wide authority on who it hires, how they are trained, and who gets to fly. Every person on that flight has the necessary chops to do what they do, and do it very well. Whatever DEI may have influenced crew selection, it has not degraded the crew's skillset or their abilty to function as a team.

I'll also tell you with some risk of personal OPSEC issues that I personally designed and approved much of what you see inside the cabin of their spacecraft. It has been tested and validated for function in very deep ways.

NASA is infected with DEI at the admin and some of the engineering levels, and it has become nigh pathological in its timidity due to the highly visible failures it's had. That's why it took so long to get SLS and Orion to fruition, but the hardware is good, and operations are still excellent.

I suspect that the high reentry speed and its associated extreme heat is going to be the most dangerous element of this mission. I wish them well.

Orion’s crew and service module have separated. The crew module continues on its path towards Earth while the service module will harmlessly burn up in Earth’s atmosphere over the Pacific Ocean. The Artemis II return trajectory is designed to ensure any remaining debris does not pose a hazard to land, people, or shipping lanes.
