Dunedin Space Programme - Earth Curve Observation

Near Space Balloon Mission

We are the Dunedin Space Programme. We launch weather balloons into near space (20-30 km high). Our aim is to capture photographs of the curvature of the Earth and measure properties of the high altitude atmosphere using sensors and portable experiments. We currently meet at the Kavanagh College Science block at 5 pm on Sundays. New members welcome.
Our first flight was launched from near Queenstown on 2 June 2014 at 11am, and recovered from near Ranfurly at 5pm.
The flight exceeded the target altitude of 30,000 metres. A photo from 31,000 metres appears below.

We are now preparing for our second flight, which will be between 1 Nov and 14 Dec 2014. The staff planning page has more details.
Principal sponsor BOC.

Read about us at in the Otago Daily Times: report on preparations, report of first flightand photos from the first flight. For more comments and pictures see our Facebook page .

For upcoming flights check flight predictions here, and follow the flight live by APRS.
