- The world has set their eyes to the planet of Mars for the next leap in manned space travel, but will they make it under current technology? Nick doesn't believe so, and discusses a few of the many hazards standing between man and Mars, as well has potential solutions to these issues, raising a call to the up and coming engineers and scientists who will be working on the mission to make sure the manned mission to Mars is a success.
Dr. Nick Devereux is a professionally trained astrophysicist, a university professor and a qualified pilot. His astrophysics research interprets Hubble Space Telescope observations of super-massive black holes in nearby galaxies. As a teacher, Dr. Devereux employs his extensive knowledge of aviation and spaceflight as a tool to illustrate important physics principles, one of which is the concept of artificial gravity. He is now an advocate for the use of artificial gravity in the next generation of spacecraft, in anticipation of future manned missions to Mars and beyond.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx
Why is it always 20 years away I'm 46 now since I was 6 it was always 20 years away
He Nailed it. Excellent disclosure
I'm surprised that a prototype has't been built yet, we only need a small habitable module, a rope connected to it and on the other end a counterweight, then you just spin the structure using a small thruster. What are we waiting for!
it needs to be hundreds of meters long.
I think he may be a bit too pessimistic about the astronauts' ability to cope with 40% g after the journey to Mars.
However he is absolutely right that we should experiment with the effects of reduced gravity environment here on LEO. If 40% g isn't enough to keep us healthy it will be a serious blow to our Mars colonization visions. But it would be easier, faster, safer and cheaper to find it out on a LEO space station.
Pasandeeros well you have to look at everything when the astronauts came back from the moon they had unhealthy side effects to their bodies and even prolonged exposure in zero gravity aboard the ISS
40% g is not enough says Isaac Arthur.
He is always the life of the party
Artificial gravity can be created in space simply by tethering two spacecraft together with an approximately 1500 meter tether, and having the two spacecraft accelerate in opposite directions. 1 RPM at 1500 meters would approximately simulate Mars gravity, while 2 RPM at 1500 meters would simulate Earth gravity. It need not be a structural truss. A simple tether would suffice. The centripetal force between two spacecraft tethered, or even one spacecraft and a counterweight, could relatively easily create the artificial gravity needed to counteract many of these health issues caused by extended weightlessness.
brabanthallen They want a complete tube between the two spacecraft in order for astronauts to be able to have more living space and storage for supplies.
Artificial gravity is already explained in the talk.
You speak of neutral counterbalance . 💯💯
