How NASA Plans To Get Astronauts Back From Mars!

The Space Race, another good video. However, at the 2:00 mark, I was surprised to hear you say that a trip to the moon (not Alpha Centauri) is interstellar travel on easy mode. I guess so, as I've always thought this trip qualifies as interplanetary, since the prefix 'inter' means 'between', i.e., 'between planets', and interstellar means travel between stars, as they do on Star Trek and Star Wars, at faster than light speeds. Right?

Some sort of nuclear powered booster should be sitting in orbit around both planets, then other craft could use these to travel to and from the moon/mars - meaning the fuel they carry is only used landing or taking off from Mars - sounds too easy to be doable - only problem is we just don't have nuclear powered boosters.

[@MaxKito2]

I mean all questions here are very valid. For instance, I’m very concerned just with the landing aspect of a vertical tower. It’s even tricky landing on earth with concrete platforms and such now imagine nothing on the surface of Mars. I know what some may say “oh we got the falcon 9 landing well” but I’d say is a starship that has landed only once and yeah it wasn’t even fully straight standing remember that. Lol There may be a lot of work on those landing legs. Then how to refuel the Red Bull can back again (The equipment men/women power to to all this) Give me a minute my head hurts😬. I mean the design of the starship is not even fully complete. Ok, yeah they say 100 people fit in it, that’s with nothing in that 35% of the tip or so of the ship cause all else is basically for fuel🚀. Food, water, equipment, and like what to sustain maybe 10sh people or less for a very short duration, since this is basically our first try. Ok I know that there will be risks involved like Elon says, but I think the risk assessment has to be greater so we can bring everyone back. 😬

[@steveaustin2686]

The legs on SN5 through SN-15, were temporary, one-use legs for testing. SpaceX is working on larger, more capable legs. The Mars Starship will likely have an engine ring around 25m off the ground, like the HLS Starship is planned to have. Those engines would be used for the last bit of landing and the first bit of launch. A Mars Starship doesn't need a booster to get off Mars and return to Earth, so it doesn't need a launch pad/tower.

@@steveaustin2686 …..Oh great 👍 that sounds more achievable. Thanks for the feedback.

And eventually yeah there will be a ferry that will run constantly between Earth and Mars, using nuclear fusion, the time it takes will be cut dramatically. Mankind must escape the earth and create life on other worlds in our solar system. Mankind will evolve and change to those living conditions. Low gravity people will be tall, and high gravity people will be short. A couple thousand years who knows what we'll all look like.

So you would only be able to talk to Mars, when your transmitter is at night and the Mars transmitter is in daytime. Because at night on Earth, you are facing away from the Sun and towards Mars. And in daytime on Mars, you are facing towards the Sun and Earth. So your signal can reach each other. Otherwise your transmitter is facing the wrong way. But if you put up comm sats around each planet, then it doesn't matter when during the day you want to talk to the other planet, because one of the comm sats is always pointing in the right direction. You just don't need comm sats in-between them as the signal can reach there just as fast by itself, as if it hits a comm sat in-between the two.
