How long can a balloon stay at a certain altitude (~14km) and what are the techniques to control the altitude? Are there low-cost ($300) methods to maintain an altitude of 14km for weeks? The foreseen payload would be around 1kg.

  • Since someone might 'write a book' on this area, it seems 'too broad' for an SE site. A good tip on 'too broad' is that it includes more than one question. Try to limit each Q&A thread to a single question. – Andrew Thompson Feb 24 '16 at 07:44
  • Thanks for your help! Should I edit this question or make a new one? I would simplify it to: How long can a balloon stay at a certain altitude (~14km) and what are the techniques to control the altitude? – wuza Feb 24 '16 at 08:23
  • "Should I edit this question or make a new one?" I think you should edit the question down to the lesser question you proposed, then move perhaps one or two of the others to new, separate Q&A threads. See how they go, (answers to one or more might show the idea to be impractical) then ask more questions once those few are answered. – Andrew Thompson Feb 24 '16 at 08:37
  • Hi wuza. I edited the title (and removed some now seemingly obsolete tags) to try to better summarize the question you are asking. – user Feb 24 '16 at 11:59
  • I voted to close this because as written it doesn't seem to have the slightest relevance to space exploration. If you left out an important fact that would make it relevant for this site, please edit that in. – Organic Marble Feb 24 '16 at 14:46
  • Hi Organic Marble. Can you suggest a stack exchange community where the question would have more relevance? – wuza Feb 24 '16 at 15:02
  • disagree on that hold, question have strong connection to communications see google loon it can be used for good and fast communications with crafts on low orbit, specially CubeSat-like. It may have strong impact on amateurs sattelites. – MolbOrg Feb 28 '16 at 21:23
  • @MolbOrg Just because the answer to a question has possible applications to spacecraft does not make the question on topic on Space Exploration. 14 km altitude is well below the cruising altitude of some aircraft, and only a tiny fraction of the distance even to the Kármán line. – user Mar 01 '16 at 14:14
  • @wuza Consider the Aviation Stack Exchange and perhaps specifically their aircraft-design tag. I suspect you would need to add details to show prior effort in answering the question yourself, however. – user Mar 01 '16 at 14:15
  • @MichaelKjörling I see your point and OP question is't well made. But it's possible to answer, that particular question, it in such way, which extends our knowledge about possible space exploration. – MolbOrg Mar 07 '16 at 03:48
  • I also ask the same question in Aviation.SE, where it got rejected as too broad. I am still interested in the answers. So any help to reopen this question is appreciated. – wuza Mar 08 '16 at 16:48
