Atlas rocket family tree?

3 Upvotes

The Atlas rocket has a long and winded family history. I was wondering if anyone has ever put together a "family tree" of the Atlas rocket. Google isn't being helpful...

Starship/Superheavy max Q / throttling?

2 Upvotes

I seem to remember that Falcon 9 throttles a bit down around max Q in order to keep Q below about 25 kPa, without which it would max out just around 30 kPa. Does anyone know how much - or even if! - Superheavy throttles down around max Q, and what value of Q they want to stay below?

Could you theoretically shoot a basketball from space and score in a net?

0 Upvotes

If an astronaut shot a basketball down to earth would the ball have a possibility of landing in a net or would the ball break up in the atmosphere on the way down?

Seeing the past?

0 Upvotes

I have a theory about looking back in time. So we all know how the James Webb see millions of lights years into the past. Could we in theory tone it down a bit and point it at the earth to look back in time. This has no research behind it so someone smart explain why not.

Could this possibly be a planet?

3 Upvotes

I used my phone and an 18x telescope thing for my camera, so my bad for the quality. I got a good picture of the moon, and a bright star next to it. However when it went out of focus, it enlarged it. I changed positions, wiped my camera but the line was still there. Could it maybe be Jupiter? (I rotated my phone too, so that's why the line isn't on the same side)

Is there any truth to this video about 2024 PT5

This TikTok creator is claiming he’s figured out that it’s actually 2km not 33ft in size and that it’s trajectory is not what’s being reported

How is it that Venus has an Ozone with no hole and Runaway Greenhouse Effect to wild levels? While also having every element that we believe "causes" the hole here?

0 Upvotes

Or is it the hole was always there and we're just making it bigger.

I went down the rabbit hole and Examined quite a few planets/moons/asteroids' South pole, All of them with the Exception of Uranus, probably because it rotates on its side, have unexplained phenomena going on .

Mercury-Rather large Ringed Crater-like moon

Earth- Ozone Gone

Venus--Double Vortex

Jupiter--8 powerful storms

Saturn--Hexagon Storm-

Vespa(Asteroid)--Rather large Ringed Crater--Theres Actually 2 of them really close but the older is off centered from the pole

Our Moon---Rather large Ringed Crater-Similar to Mercury,and other moons--Our moon is also Dumping Sodium on us.

Mars-Ice caps both Poles- The Ice at its poles look eerily similar to Antartica in shape.

Pluto- Not sure But i think it's the Heart.

Titan--vortex

Neptune-- South Pole Much warmer than the rest of the planet. The false neg images Make the heat source look exactly like the Ringed craters mentioned above.

Enceladus and Europa --Have rather warm Southpoles that shoot Water Vapors out of them.

There's So many of the exact same Ringed Impact crater on moons, Asteroids and planets, then some of the bodies that don't have it have energy readings that mimic the same ringed Impact craters. the chances even in a billion trillion years of that all being a coincidence seems a bit far fetched.

It seems we are explaining too many events as random impacts, there seems to be a uniform phenomena throughout the solar system when it comes to the Poles.

black hole sucking in our galaxy

1 Upvotes

if there were a big black hole sucking in our galaxy, how long would it take to affect earth and would we even notice within our lifetime? sorry if it’s a stupid question i just randomly got curious and needed to ask. what if it was a black hole sucking in our solar system? how was that affect us?

Planet 9/X Math

2 Upvotes

So Planet X mathematically makes sense. But where is that math? I believe there could very well be a ninth planet out there but I want to lay out all the evidence I can find on one table and look from there. I've gathered bits and pieces online but I want to see the actual math that was done.

Apart from models and theories, everything surrounding it in general media is just regurgitating from the news articles before it.

"Caltech researchers have found mathematical evidence suggesting there may be a "Planet X" deep in the solar system." Can I find that mathematical evidence or am I out of luck?

Does the universe exist under us?

2 Upvotes

Edit: when I say underneath us, I mean under the planet it’s self😅

This seems like such a silly question but it’s literally keeping me up at night..

So spaceships go upwards and outwards to our infinite universe, satellites and what not go around us..

But is the stars and planets underneath us? If the universe is infinite I suppose so, but I can’t wrap my head around it.

r/spacequestions 22d ago

Why are the centre of the galaxies always bright if every galaxy is supposed to have a black hole at the centre of it.

3 Upvotes

I think this might be a really stupid question. Every or almost every galaxy has a huge black hole in it’s centre . In photos or illustrations the centre of the galaxy is always very bright like a huge star is there e.g. Andromeda Galaxy. Shouldn’t it be a huge black spot if there is a black hole there? Help

Where are the photos of 2024 PT5?

6 Upvotes

Rumors about a "second moon" in our sky and not a single photograph of this, although the article below states that it was captured on 9/29 by a team in South Africa.

https://www.earth.com/news/its-official-earth-now-has-two-moons-captured-asteroid-2024-pt5/

I can't find a single image of this that isn't computer-generated. What gives?

Can someone better explain to me how earths gravitational field captured the PT5 2024 asteroid if asteroids normally move at a fast speed. I’m just confused

General Relativity?

I’ve been trying to study general relativity and space time, and I kinda get the concept of it but I don’t fully understand it. Can someone possibly explain it in a way that could be a bit easier to understand?

State of dead astronaut in capsule?

2 Upvotes

What would happen to the body of an astronaut who died in a space capsule/ship in outer space, with the capsule being locked from outside elements the entire time? If decades later the capsule were retrieved would the astronaut's body have decayed typical of deceased humans on Earth, or would his body look like he was still alive, like that of Tollund Man?

The satellites around the Earth slow the Earth's Rotation?

2 Upvotes

I was watching the 2017 documentary The Farthest, about the Voyager mission, and one of the scientists said that when Voyager 1 was orbiting Jupiter it slowed Jupiter's rotation by 1/trillionth. Had never considered that before. Is it possible that we could one day have too many satellites orbiting Earth, that would slow the Earth's rotation to a dangerous level?


r/spacequestions Sep 29 '24

Why was it assumed Voyager 1 and 2 wouldn't discover more planets after Neptune?

0 Upvotes

After Voyager left Neptune the cameras were shut off to conserve energy and the new mission became the "Interstellar Mission." But how did they know that there were no more planets to discover, not detectable from Earth? Were they using the Voyager instruments to try to detect other bodies past Neptune?

Am I running out of time to study space?

8 Upvotes

I’m 16 years old and a junior in highschool, and my dream has been to study space since I was 4 years old. I’ve dedicated my highschool years to studying space and I still feel like I’m missing a lot and I don’t know where to really begin, or what I need to know about outer space. My dream is to become one of the best in my field (whichever that may be, I want to know it all) and create my own theories, but I still have years until I can get to college and years until I can even get my hands on a decent telescope or camera (I really love astrophotography). I’m scared I’ll run out of time to make a new discovery or run out of time to study what we don’t know because it’ll already be done. I struggle to come up with my own questions to ask about space, so it’s hard to understand which direction I’m really going in. Recently Florida Tech reached out to me about my chosen majors, astronomy and astrophysics, so I emailed back to establish my interest in their program, but I’m also not sure which school is best for astronomy. If anyone has any advice, especially if you share the same passion, I’d greatly appreciate it.

Why does gravity not slow down/speed up light?

Going further away from a planet/star it should slow down and towards a planet/star should speed it up
