SuperBIT high altitude astronomical balloon completes mission

After almost forty days circling Antarctica and taking high resolution images of galaxies and nebula, NASA SuperBIT high altitude astronomical balloon completed its mission today, landing in Argentina.

Having identified a safe landing area over southern Argentina, balloon operators from NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, sent flight termination commands at 8:37 a.m. EDT, May 25. The 18.8-million-cubic-foot (532,000-cubic-meter) balloon then separated from the payload rapidly deflating, and the payload floated safely to the ground on a parachute touching down in an unpopulated area 66 nautical miles (122 kilometers) northeast of Gobernador Gregores, Argentina. NASA coordinated with Argentine officials prior to ending the balloon mission; recovery of the payload and balloon is in progress.

During its nearly 40-day journey, the balloon completed a record five full circuits about the Southern Hemisphere’s mid-latitudes, maintaining a float altitude around 108,000 feet. In the coming days, the predicted flight path would have taken the balloon more southerly with little exposure to sunlight, creating some risk in maintaining power to the balloon’s systems, which are charged via solar panels. The land-crossing created an opportunity to safely conclude the flight and recover the balloon and payload.

The picture above, cropped, reduced, and sharpened to post here, has incredible resolution, illustrating the advantage of flying a telescope on a high altitude balloon.

NASA’s second super pressure balloon develops leak, forcing termination of mission

After only a day and a half after launch NASA’s second super pressure balloon, this time carrying a detector for studying cosmic rays, developed a leak that forced its controllers to terminate the mission.

The scientific balloon launched from Wānaka Airport, New Zealand, May 13, 12:02 p.m. NZST (May 12, 8:02 p.m EDT). The balloon was in flight for 1 day, 12 hours, and 53 minutes before termination over the Pacific Ocean May 14 at 12:54 UTC (8:54 a.m. EDT). The launch was the second and final for NASA’s 2023 New Zealand balloon launch campaign.

During flight, the SPB began experiencing a leak and teams attempted to troubleshot by dropping ballast to maintain the balloon’s altitude. The determination was made to safely terminate over the Pacific Ocean. NASA will investigate the cause of the anomaly.

Meanwhile, the first balloon, dubbed SuperBIT, continues to fly, presently on its fourth circumnavigation of Antarctic while its telescope takes high resolution images of celestial objects.

SuperBIT balloon circling Antarctica snaps more high resolution astronomical pictures

The Super-Pressure Balloon Imaging Telescope (Super-BIT) that has been circling Antarctica for the last two weeks has now obtained two more more high resolution wide-field astronomical pictures.

The picture to the right, cropped to post here, is of Messier 104 (the Sombrero Galaxy). While the telescope cannot zoom in closer than this to such objects, it is able to get much wider and sharp pictures, covering an entire galaxy or nebula that ground-based telescope using adaptive optics (designed to counter the fuzziness caused by the atmosphere) cannot. Adaptive optics only work on very small fields of view, thus making it unable to observe some of the larger nearby astronomical objects like galaxies and nebulae.

If you look at the live stream of the balloon’s track, it has now almost completed its second circuit of Antarctica.
