After a most successful balloon flight, BLAST finally landed at 06:15 UT on 16 June on Victoria Island in Canada. The submillimeter telescope obtained over four days of data in near space that will help scientists understand the evolution of the universe.

The launch at Esrange, the flight over the Atlantic, and the landing in Canada went according to plan. The recovery operation is taking place now and should be completed within the next week. The payload will be partially disassembled at the impact site and transported back to the Cambridge Bay by helicopter and aircraft. Then it will be returned to the scientists at the University of Pennsylvania. So far, the recovery is proceeding very nicely. Scientists on the scene report that the experiment sustained only very minor damage during the landing and that it is in excellent condition. They hope to refurbish the instrument and fly it again within a year or two. Most of the data was stored on board the instrument during the flight. The data vaults have been removed and the scientists will soon begin analyzing the data. Preliminary results are expected within a few months but it will take a few years to analyze all the data. 

"The flight was an unqualified success", said David Pierce, Chief of NASA's Balloon Programs Office. "NASA and Esrange have demonstrated an important new way of doing world class science from balloons in the northern hemisphere. We hope that both the US and European science communities will take advantage of this new capability now that we've shown it is possible", said Pierce. NASA's Balloon Program is managed from Wallops Flight Facility in Virginia.

NASA plans on conducting balloon these campaigns from Esrange every year during June and July. Plans for next year call for two or three large payloads. A cosmic ray detector, TRACER, from the University of Chicago and the Deep Space Test Bed, an experiment to determine effects of long term exposure to space radiation on astronauts are the leading candidates for flights next year.
