DailyDirt: High-Flying Balloons FTW!
from the urls-we-dig-up dept
Before the Wright brothers and planes, people had actually flown in hot air balloons as early as 1783. Those early balloons didn't travel that far -- just a few miles or a couple dozen miles if the balloons were filled with hydrogen. Blimps (aka airships) were somewhat common in the early 1900s, but obviously that mode of transportation didn't really stick around after the spectacular demise of the Hindenburg. Perhaps we're due for a comeback for more advanced balloons now?- World View's commercial balloon rides at high altitude are a relatively cheap way to get close to the edge of space. They've successfully tested the first parafoil at stratospheric heights, and this near-space vehicle will also carry scientific equipment for unmanned missions to the upper atmosphere. [url]
- NASA is developing scientific "super-pressure" helium balloons that can last for months in the upper atmosphere. It's not easy to keep a balloon aloft for that long, but NASA is still working on it to float telescopes above the clouds without an expensive rocket launch. [url]
- The BLAST telescope was designed to hang from a high altitude balloon, and it's successfully gathered data on star formation. Unfortunately, the telescope was badly damaged in one of its landings, but it was repaired to fly again in 2010 for 9 days. [url]
- Google's (or Alphabet's) Project Loon has balloons that can fly for well over 100 days -- and some have even lasted over 200 days. These balloons need to survive high altitudes and cold temperatures, and hopefully they'll start to deliver reliable wireless broadband internet soon. [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.

“Still Flying
Huh, nice to see some links to BLAST on Techdirt! We've upgraded our systems are are looking at another flight next year. We're at a 30 day flight with over 2,000 pixels this time.
