We’ve all seen the movie. The first human mission to Mars descends towards the ochre-coloured surface on a roaring column of rocket thrust. After touching down, the astronauts clamber down the ladder, plant a flag in the soil and snap some photos of their footprints.
We’ve done it on the Moon, so why not Mars? Aside from all the hazards that would need to be accounted for in order to ensure astronauts survive the journey to Mars, (such as exposure to cosmic radiation and the effects of space on human genes), the landing itself could actually be pretty problematic.
Philip Metzger and his colleagues at NASA’s Kennedy Space Center in Florida are raising the alarm over an issue that could potentially be very significant for human missions, but has received barely any consideration until now.

Have robots build a landing pad with sides that curve up slightly.
Exactly! I used to have a lot of contempt and scorn for those who dared to express doubt about the Moon Landing.
That was back when I had a lot of trust in my Government to always be truthful with the public. Now...Jury’s still out.
Haven't even done it with robotics yet. I can see how parachutes could be employed, even in the thin atmosphere of Mars to help slow the descent, but humans will be hosed once they are landed.
Unless it turns out that all those UFOs the government is talking about are some kind of secret antigravity technology from Lockheed, then we won't be doing any manned round trips to other planets any time soon.
“Mars is subjected to wind storms with wind speeds of 400 mph for weeks at a time. “
But Mars’ atmosphere is 1% as dense as the Earth’s so those winds have the force of a 4 mph breeze.
That was the biggest error in the Martian movie. The wind on Mars would have no effect on their spacecraft beyond a light coating of dust.
I think the first vehicle for people on Mars will be a slightly modified Tesla because Who wouldn't want to own a car that had been driven on Mars? Elon already put a Tesla in space and it was marketing genius.
If would be one thing if the moon landings were the only lie. Sadly, that's the least of it.
WW1, Titanic, WW2, JFK murder, 911, Covid...
The Titanic??!! Oy!
Thanks for the info. A lot has changed since my days of high school science.
Getting to at least triple redundancy for manned missions, increases the costs over 10 fold vs. an unmanned mission.
Not to mentions that we can also include all the material analytical tools on the trip and eliminate the need for a return flight.
Just figuring out how to do so and doing it are reason enough, and in any case, private companies will soon have the means to do so without the government being directly involved.
What? Are they going to capsize it?
And I sure hope Mars or some other place is made habitable because that will be the only freedom alternative to what the U.S. and world will become.
When our astronauts put the American flag on Mars, how did they get back to earth?
But Mars’ atmosphere is 1% as dense as the Earth’s so those winds have the force of a 4 mph breeze.
They drove back to the moon, then to Chicago.
Back to Chicago? That’s why Sheila Jackson-Lee, down there in Houston, was ill-informed. (If only there was a NASA Visitor’s Center near where she lives so she could learn about our space exploration.)
You’re a lunatic.
