The scientific balloon is expected to launch from Wanaka Airport in mid-April. It will run for about 100 days – floating at an altitude of 110,000 feet (33.5 kilometres) and sending back scientific data.

The Compton Spectrometer and Imager science team from the University of California-Berkeley will be on board.

The balloon will run for about 100 days – floating at an altitude of 110,000 feet.

It will be the fourth time a SPB has launched from Wanaka since Nasa began balloon flight operations there in 2015.

In 2017, disaster struck when a balloon sank to the bottom of the Pacific Ocean, after a leak forced a controlled sea landing 12 days after launch.

The balloon is 532,000 cubic metres in size when fully inflated.

The balloon and payload worth several million dollars could not be recovered. The exact cost of the upcoming mission is not yet known, but the 2017 balloon cost about NZ$1.6 million. 

Nasa communications spokesman Jeremy Eggers said changes had made to ensure the balloon stayed pressurised during the heating and cooling of the day-night cycle.

Balloon Program Office chief Debbie Fairbrother said the upcoming mission would be key to figuring out whether the balloon could be used to support larger and more complex science missions in the future.

“We’re excited for our return to Wanaka and look forward to conducting outreach, meeting with local leaders, and ultimately sharing all of Nasa’s work with the global community,” she said.

Queenstown Airport Corporation chief executive Colin Keel said it was a “privilege” to host the balloon program, which provided “many benefits” for the local community.

Nasa and the airport entered into a 10-year arrangement in 2017 to launch the balloons from Wanaka.

Another mission is expected to launch next year. The flight will be a test for the balloon launch of the US$40 million Galactic/Extragalactic ULDB Spectroscopic Terahertz Observatory (GUSTO) mission from Antarctica scheduled for December 2021.

It is set to be the largest mission ever launched on a Nasa balloon and will measure emissions from the interstellar medium – the cosmic material found between stars.

The data from GUSTO will help scientists determine the life cycle of interstellar gas in the Milky Way galaxy, witness the formation and destruction of star-forming clouds, and understand the dynamics and gas flow in the vicinity of the centre of our galaxy.
