Announce : footage release of our stratospheric balloon eclipse flight

Hi,

This is to announce that the joint Romanian-Australian team have released the footage of our stratospheric balloon eclipse flight, Eclipser 1 which successfully captured footage of the eclipse from 25000m(82000ft) altitude. After the eclipse, it continued to rise to a maximum altitude of 36800m(121000ft) which we believe is the third highest flight recorded in Australian airspace.

I recommend you set quality to HD1080 and watch on a big screen but take a travel calm pill first. It's very blair witch - quite the wild ride.

You can see the Moon's umbra approach from the west before the eclipse starts. The umbra is clearly visible out to sea for some time after the end of totality. The balloon continues its ascent to 36800m then bursts. At burst altitude the temperature is about -80C and pressure <1% of sea level so when the latex balloon bursts, shards of brittle rubber go flying in all directions with almost no air to slow them down.

You see the capsule tumbling as it free-falls for 19000m. Then at 18000m altitude a parachute deploys and it comes back to earth. Of course, the chute got snagged 20m up in a tree posing one final hurdle for the recovery team.

Here is the link to the balloons APRS tracking. This was broadcast live during the flight and used by Air Services Australia to track the position in addition to the periodic call ins at each 10000 foot level.
