DailyDirt: Life on Mars
from the urls-we-dig-up dept
Manned missions to Mars have been in the works for decades, but we still haven't worked out all the details for getting humans to safely set foot on the red planet. Technology has clearly improved since the 1970s, so we're likely closer to solving the challenges of landing people on Mars than ever before. Some astronauts might accept a one-way ticket, but it might be nice for those adventurers to have a committed, long-term supply line so that their excursion lasts as long as possible. Here are just a few links that might be interesting for future astronauts.- Curious features on the surface of Mars could be explained by blocks of dry ice carving out tracks as they slide down slopes, leaving behind odd "linear gullies" after the frozen carbon dioxide sublimes. If any one-way astronauts make it to Mars, they should try out this kind of snowboarding, #YOLO! [url]
- Ancient plants found on Earth could help us look for similar kinds of life on Mars. Bryophytes might be more easily grown in the harsh conditions of space, and some of these plants can reprogram themselves to adapt and grow into different kinds of plants. [url]
- The Office of Planetary Protection tries to protect extra-terrestrial environments in space from contamination caused by human activities. But preventing biological contamination from Mars-bound spacecraft could be a waste of effort and funding, according to some scientists. [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.
