Mars in 3 Days?

[Nuthin' Fancy]

By far, the dumbest ideas ever proposed.
A massive waste of $$$, it always has been.

No other planet has oxygen.
The very same gas every living creature on earth, needs to survive.
People can produce oxygen though electrolysis but not that large a scale to sustain anything larger than what they have on the space station.

How would you stop?

Flip the ship at the half-way point and fire the rockets.

But enough about the AGW scam.

The video talked about accelerating to the half-way point and then decelerating.

Seems that as they develop the speeds necessary for efficient space travel, they would also develop a reverse thrust to deaccelerate and stop?

But however it is done, I think we should never underestimate what the possibilities can be. Who would have thought even 20 years ago that a huge industrial structure would be underway to utilize AI? For good or bad it is something we and future generations will live with as 'normal'.

As recently as the last century, we believed mach speeds would be unachievable and, even if we achieved them, would not be survivable by a human. Until Chuck Yeager did it and was perfectly fine physically. Now it is routine for military aircraft and achievable for commercial flight--the Concord--though public disapproval has prevented supersonic airliners from becoming commonplace.

Now, despite the movie "Top Gun Maverick"--I love the movie--based on achieving hitherto unimaginable speeds--the general consensus is that humans cannot survive mach 10. We probably won't know until somebody does it. Right now the Blackbird at about mach 3 is currently the fastest aircraft and a space capsule reentering the atmosphere is also traveling about that fast. I think the fastest speeds achieved by manned spacecraft in space is a bit more than that, but less than mach 4.

Our local Sandia Labs, among other things, is working on developing weapons that can travel up to mach 5 and be more effective in shooting rockets and missiles out of the sky.

I believe the Expanse is based on the discovery of the Epstein Drive which allows for dramatically stronger continued thrust, but even they can't do interstellar travel until discovery of the Ring technology.

However the topic is interesting. Nuclear engines, ion thrust engines etc are really cool.

This may change my mind about the possibility of interplanetary space travel. The science comes from The Expanse sci fi series which takes place at the same time as Star Trek -- around 300 years in the future. The difference is The Expanse used realistic science and doesn't depend on folding Space Time

Some years ago, I spoke to someone who worked on the Apollo Project. He stated that speed is one thing. It is getting into orbit from that speed. This program may have had an answer for it.

There's nothing of value on Mars ... with technology to get there in 3 days is available ... then we have the technology to get resources from Earth ... no reason to try and distill rhyolite on Mars ...

Robots can do the same jobs as humans only better ... and without whining about oxygen ... yeesh, what next, gender specific toilets in the capsule? ...

Humans arent intelligent enough to acvomplish this. Ever.

Sending $billion robots to Mars is stupid too.
