NASA's NEW Nuclear Mars Rocket Engine is somehow better & faster than SpaceX Starship...
Six months. This is the period that Elon Musk has estimated for the journey to Mars with Starship, the vehicle is currently operated by a total of 39 Raptor engines.
But you know, six months is very long for anyone, including you and me. And of course, NASA also doesn’t like that.
Therefore, NASA revealed a new engine that will use a new energy source. They claim that it will be more powerful, safer, and can get humans to Mars faster than the Starship and Raptor engines.
So what is that engine? How it’s better than the SpaceX Raptor engine? Why NASA is so confident with its engines?
Stay tuned as we dive and more in today's episode of Alpha Tech!

NASA doesn't have a new Nuclear Rocket engine. they have a study on paper saying "yeah, this could be cool if somebody made one." there is a company in england that is actually building and testing such an engine, and has discussed a partnership with SpaceX. For comparison the Raptor was in use in 2019 and has been scaling up production since.

might see a demo in 2040 and 50 billion later

[yondu]

It will take NASA 70 years to build it and it will be way way over budget.

If i got a buck for a every super cool plan the NASA came up with and then failed to deliver after we ended the Moon missions, i would be a billionaire

[MrBigDave]

This rocket engine would not replace the Merlin or Raptor engines. It would only be used while already in space.

[jackmorrison]

I love all these stories about NASA inventing stuff, meanwhile they use 40 year old tech, and techniques

[jimbeechDasher]

Can I suggest Space X to launch on a Starship then the nuclear is tested in space rather than it blowing up in our atmosphere !

[ThomasDillon-zu]

One day we will be building nuclear rockets on the moon where helium-3 is abundant and the material needed to build them will be available.

[dingdongheadyuue]

The huge problem besides COST is complicated, as hydrogen is almost impossible to seal being the smallest molecule, as small as its atom. Dreaming

[jakubniegut]

Spacex will colonise Mars 3 times before NASA will launch rocket with that engine

[richard--s]

SpaceX would not hesitate to include new better engines. Why not.

But they are not available yet. Let them first learn to fly a reusable big rocket. It's a word first. No one has done this before.

Then when better engines are on the horizon, they can develop them further and use them in their spacecraft.

But don't wait 50 years until these new engines become available. Use what we have.

And by the way, what do you expect on Mars? It's the same as in open space. No air to breath outside. You have gravity, congratulations! But nothing more. You don't win anything when you arrive faster on Mars. You also have very tight crew spaces on Mars. It's not a big relieve once you are on Mars.

Starship has already reached
orbital altitude and velocity

[JJ-jxkd]

If it is NASA claiming this they should have it ready in about 50 or 60 years and about 10 times the actual budget judging from their track record .

[johnbrobston]

Odds are that if this thing is built it will be launched on Super Heavy. Nobody's going to allow a nuclear rocket to be launched from Earth--too much radiation in the exhaust.

[Orozco_PNW]

Though this is likely many years away, it at least doesn't obsolesce the Starship because Nuclear Rockets will likely never be used for orbital launches, but rather as an interplanetary express.

The problem with traveling at 500, 000 mph is how are you going to shield the spacecraft from hitting even tiny micrometeorites? The kinetic energy, KE, involved in a spacecraft traveling at a relative velocity, v, with respect to an object of mass, m, is equal to KE = 1/2·m·v^2. Therefore, decreasing the time required to get from Earth to Mars from 6 months, or 180 days, to 45 days is a 180 days/45 days = 4X increase in speed. The spacecraft would therefore be subjected to a possible 16X increase in kinetic energy collisions with any objects, such as micrometeorites. This is a parameter that will have to be accounted for in the spacecraft design.

From the perspective of anyone with the broadest knoledge of the subject, this is truly offensive clickbait. I gave the video 35 seconds where you affirmed the bullshit statement in the click bait title and I click off. Do better...

[spacecadet]

I am guessing that tis channel is now an AI channel by how many mistakes are in this video. Youtube, please ban all AI channels and AI made videos.

[emameyer]

if this works, Starships can be used as cargo ships. so still plenty usefulness there

[dfxvoodoocards]

NASA cannot even send people to the Moon…
