SPB

Nasa has announced that its super pressure balloon (SPB) has completed the first leg of its circumnavigation flight, as it aims to fly it continuously for more than 100 days.

The agency intends to fly the SPB more than 100 days with an aim to go beyond the current record of 54 days in flight.

Launched in March from New Zealand, the SPB flying due east has reached Australia from the south, just west of Melbourne. It will fly in a northern direction for several days before eventually continuing east.

Nasa balloon programme office chief Debbie Fairbrother said: "The balloon is healthy and performing as designed.

"The SPB balloon technology is designed to facilitate low-cost scientific investigations at mid-latitudes in a near-space environment."

"We’ve had tremendous support from Australia in coordinating the balloon overflight."

The programme aims to evaluate the capabilities of the SPB to fly long duration missions at a constant altitude.

The SPB balloon technology is designed to facilitate low-cost scientific investigations at mid-latitudes in a near-space environment.

Made from 22 acres of polyethylene film, the balloon is filled with helium to carry tonnes of payloads.

The SPB carries a 5,000lb payload, which includes tracking and telemetry systems, to monitor its position and health.

The SPB programme is managed by Nasa’s Wallops Flight Facility in Virginia with ten to 15 flights each year from launch sites worldwide.
