NASA does mission concepts like this all the time, there are dozens in [NTRS](https://ntrs.nasa.gov/) btw
where any people so long in space and not, at least partially, protected by the earths magnetic field?
Well, not possible anymore as SLS just got canceled by the Trump administration :/
There is zero scientific value in a manned flyby of Venus. Robotic missions sure. Why would you even propose this kind of make-work for the SSL?
Edit: Didn’t realize it wasn’t a separate mission from Mars mission. That said, Starship is investigating 90 day trajectories, basically by using more fuel. Conventional missions take like 180 days. You aren’t saving time with this trajectory, you’re saving fuel because you’re woefully underpowered for what you’re attempting. If the Sun thru off a flare during this time I doubt you’d have enough shielding to survive. Sun radiation will be 4 times as intense close to Venus as it is to Mars, as mars is twice the distance from the Sun.
Edit2: Actually losing points having added a correction. People hate Elon so much that they will downvote a Starship mention. I’m not happy with Elon either, but which would you prefer, Starship failing or Starship getting to Mars, because I guarantee outside of Starship, no one else is getting there in my lifetime (66 years old and watched the Apollo 11 landing on the Moon on TV).
So, its radiation death then? I guess this is what happens when you fire all the scientists. NASA’s own limit for lifetime exposure is equal to 16 days outside the earth’s magnetic field, assuming you are outward bound. Getting that close to the sun is much worse, since the neutron flux is much greater. Gadolinium could help with the neutrons, but you need a reactor’s worth of power for magnetic shielding (or meters of hull thickness).
And that idea is to move around the Orion capsule while having +3 ~~kerbals~~ astronauts cramped in it for 1 year and a half?

a year and a half is a long time with no new Doritos.
Imagine being stuck in your house for a year and a half. And it’s always nighttime. And any little mistake could mean your horrific death.
yikes….
Nice to have concepts. Its only About 1300 days ( or a couple more Big Macs ) before you can have a budget to do anything again.
That seems slightly more plausible than the folks doing it with poorly translated books.
I remember seeing a documentary back in the late 2000s mentioning this idea.
A fast trip to Mars does have some benefits (less supplies, less exposure time for radiation, less time in space for the crew, etc.).
But the big reason why most Mars missions tend to take the “long stay” approach is because of how inflexible the “short trip” can be. There’s a lot of science that NASA wants to do in the red planet, a lot of which can not be crammed or monitored in only a month of work alongside everything else.
But more importantly, if anything goes wrong, there’s a very brief window to fix it before either the Mars or the Venus intercept gets missed; especially since both would be fly-bys rather than captured orbits. Even though a long stay does mean surviving Mars for a couple years, the risk of missing one transfer per burn is arguably lower than the risk of missing one of 2 transfers or the rendezvous with the return craft.
I wonder if they do concepts for crazy technology advances. What if scenario’s
I have been following this tech since last year. [https://www.universetoday.com/articles/the-first-all-electrical-thruster-the-ivo-quantum-drive-is-headed-to-space](https://www.universetoday.com/articles/the-first-all-electrical-thruster-the-ivo-quantum-drive-is-headed-to-space)
Probably will not going to work but they are turning on the drive on a satellite in a few weeks.
We’ll find out if it works or not.
Has someone done a video on this? would love to hear and explanation.
I know this is only an illustration, but wouldn’t they launch when Earth and Mars are at their closest?
Is there gravity in this MTH?
Weren’t we hearing only a few months ago that permanant kidney failure would happen in a journey long enough to reach Mars.
