DailyDirt: Missions To Mars
from the urls-we-dig-up dept
The future of manned spaceflight to other planets is a bit uncertain nowadays, but there are still plenty of people who are working on plans that could lead to people walking around on Mars before the end of the century. In the meantime, unmanned missions will have to suffice, but here are some quick links on traveling to Mars.- Landing equipment on Mars that weighs anywhere near 40-80 tons (on Earth) is just out of the question using current technology. The Mars Science Laboratory weighs about a ton and it's about as big as we can go right now... and we'll see how it does later this year. [url]
- SpaceX's CEO Elon Musk wants to send people to Mars in 10-20 years. It would be interesting if a private company lands on another planet before any nation does. [url]
- Studying 12 generations of worms on the International Space Station could help us better understand how humans will survive indefinitely long trips in space. So Caenorhabditis elegans could be the first animals sent to another planet, instead of dogs or chimps. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Space Stuff
Also it is never good to describe NASA in terms of current technology when every single space mission they do leads to implementing new technology.
Yes it would be interesting if SpaceX can make Mars first but their estimates are normally far too generous even if they get their in the end. The real first goal of commercial space should be a free return trip around the Moon.
NASA ix usually flying worms or some small creatures. Most interesting is that they don't take their astronauts beyond a six month ISS stay.

Re: Space Stuff
1) muscle atrophy and bone loss - Either artificial gravity or a lot of working out. Landing would otherwise be problematic.
2) high energy particles and radiation - humans would need to seek shelter if hit by a storm. Said shelter would probably be lead based and small due to weight restrictions. Lack of exercise would become an issue, see number one.
3) fuel for return trip - need easily obtained resources and refining equipment on Mars for making fuel. Should send the equipment first via robot.
These are just a few of the items yet to be solved as far as I know.

Currently they plan to use one with large solar arrays to move large cargo mass between Earth orbit and Luna orbit. It would take weeks on pulsed battery charge thrusting but it is very efficient.

With an atmosphere as thin as it is on Mars you cannot count on atmospheric friction to keep you from reaching terminal velocity.
As well as greatly reducing the effectiveness of parachutes.

And planetary capture becomes even more problematic when increased velocity is used to decrease the travel time.
Aero braking has been successfully employed several times with much smaller spacecraft. Without such techniques, additional fuel is necessary to obtain planetary orbit.

Google Mars
My money is on Google sending some guys in a street view car, it's currently missing from www.google.com/mars

Dude they could claim the red planet as theirs.
