NOT RIGHT: Nasa campaign manager Dwayne Orr says conditions have to be perfect for the balloon launch.

SUPER-PRESSURE: A Nasa balloon similar to the one to be launched at Wanaka.

A Nasa balloon launch attempt has been cancelled because of opposing winds, disappointing a small crowd gathered at Wanaka Airport.

The Nasa super-pressure balloon was due to lift off between 8am and 10am on Monday in Wanaka.

Mission boss Debbie Fairweather said it could be Thursday or Friday before another launch was attempted.

"We had a test run and it was a no show . . . we are used to this," she said.

"It is part of the nature of our business."

In Sweden, the team waited for a month and a half to launch and did 24 early-morning starts in a row before conditions were right.
