450 million K, is quite a jump
But she's OK, despite the bump
Hearty congratulations to InSight,
And NASA for getting it right.
But the credit's all for Trump!
@wolfgang59said InSight has landed.
About 3 hours ago.

What 'bump'? It was only about 150 million Km when it got to Mars, not 450.
Seriously, I think real manned Mars mission needs to wait till VASIMR gets developed, because if humans go to Mars at present speed, taking 7 odd months, the chances of a high rad incident is pretty high. It won't do much good if the humans arrive at Mars dead.
VASIMR fixes that problem by getting folks to Mars in ONE month not 7 so there is that much less chance of getting fried by a solar storm.
How that works is you have a rocket that gives a gentle thrust 24/7 instead of a giant push lasting an hour. They talk about VASIMR only giving about 1/20th of a g but 24/7 instead of 3 g for an hour.
The result has two huge consequences. First, you acell halfway, then decel the rest of the way and that does 2 things, One, at 1/20th of a g you end up average velocity 7 times that of our present tech. Two, you end up at the end of the journey with zero velocity compared to the planet, which means you can then use Mars gravity to pull you in but you come in a HELL of a lot slower than present tech slamming into the Martian atmosphere at 12,000 mph and like the Insight, hit about 8 g's by atmospheric drag. Instead you max out at around 3000 mph and so a lot less heat load to get rid of by the heat shields.
But a lot of technology has to be worked out to make it work with a couple hundred tons of payload. Like nukes capable of putting out a couple hundred megawatts also 24/7 for the whole month.
@sonhousesaid My slide rule is bigger than your slide rule😉

Instead of posting all this ‘stuff’ why didn’t you just acknowledge that Wolfgang59 was correct?
Looking forward to the photos it will be sending back.
The last one sent back photos of a squirrel identical to the ones found in the Canadian wilderness.
Strange that.
