I guess that at 130,000 or so feet up the atmosphere becomes fairly stable, but this just does't seem to be stable enough to me. Goes to show how wrong I must be. The article didn't discuss recovery of the telescope though.
STOCKHOLM, Sweden - NASA launched a scientific helium balloon from northern Sweden on Sunday with a telescope for studies of star formation, a spokesman for the Esrange launch pad said.
The launch is the first in a series of giant balloons which NASA has organized to transport bulky payloads such as astronomical telescopes used in astrophysical experiments and research on cosmic radiation.
The westward flight from Esrange to Alaska will test NASA's new long-lasting balloon vehicle and carries a 5,940-pound telescope at an altitude of 25 miles for six to nine days.
