Next weekend, if everything goes well, a 15x30cm carbon deck will fly onboard HAPS-1 -http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1
One end of the deck will be the flight radio, the other is my responsibility, a single camera (Powershot A560 ), stand alone GPS logger (to 18km), and a small wide angle mirror so the camera can see the payload, the chute and the envelope above. Still working on a hacked firmware for the A560 - but the intention is every minute will include 15s of video, and then 5-10 stills in fairly quick succession - with the hope that the rotation of the balloon will give us some mosaics out of each section. More details, some photos etc, later in the week. |

About the same as what I reckon. That'll be Denmark on the horizon, and on the far right not shown on Doug's overlay should be The Netherlands. Pretty much the whole North Sea there.
I matched up the bit of East Anglia in that shot, it's the very northern tip. Pink lines show the ballon trajectory in the forground. The earth really does look like Google says it does; only bluer! -------------------- |

Just when I thought it couldn't get any better, the image wizards step in. I knew that if and when this worked, I would see you guys come up with every mosaic and analysis an interpretation - far quicker and far better than I could. I just tried to get the best data I could to feed the machine I now understand, perhaps a bit more than most, how and why Steve and Jim and Alfred and Pete do what they do. I now also can not understand, more than ever, why Europe does the opposite. But I can tell you I know EXACTLY why the ESOC guys have turned that VMC back on. |

For our foreign friends, it's probably worth mentioning that The Wash ( that U shaped bay ) would appear to change a lot from altitude, as it's almost all very very shallow and produces large sand-banks at low tides. It's the venue for the story of King John's Treasure ( probably false ).

Ah I know a bit about The Wash and St. John's Treasure and The Fens from Louis L'amour's Sackett series. There's nothing more entertaining than historical fiction.

Fantastic stuff; the video is just hypnotic. I also wondered about some sort of weather vane to at least slow the speed of the oscillations (though no oscillation = no pan) but the risk of tangling the chute would be non-zero. Would that be the purpose of the boxkite-like affair ISTR seeing in photos of met balloons?
That dark sky and curved horizon is so, so tantalising... hmmm a quick Google turned up this report of a 100000' rockoon launch reaching "30-36 miles apogee", and the HAL5 HALO project which seems to have gone quiet in recent years(?) -------------------- --

Now THIS is what I always wanted from the UMSFB/HAPS-1 project - 360 degree panorama!
Click image to go to my (never before used) blog with various sized download options. I'll have a look for more images to try and fill in the foreground tomorrow. Enjoy, James -------------------- |

Oh my... this is seriously becoming APOD material
The next balloon better have gyros for attitude and pointing determination so panorama stitching can be automatized. -------------------- |

Here's a Photosynth of the first 70 photos (only 20% Synthy, it can't match up about half of the images) that is pretty cool once you get used to the viewer interface. It matches and stitches the images, but Photosynth unfortunately can't output a panorama or mosaic.

Added a spherically distorted and otherways modified version of the NOAA-18 image to the blank spot to try and fill in the gap:

Hello to the forum and congratulations...
May I ask about the complications involved to "clear" this flight ? Is the BAA not "down with this sort of thing"... I'm quite "undulled" as a Scotsman myself... cheers All, Eoin -------------------- 'She drove until the wheels fell off...'

I played with some images around the horizon, lining them up and looking at the horizon to black sky transition around the mosaic:
I think you can see some forward scattering (brighter towards sun) haze layer boundaries (indicated by black arrows). There also appears to be a definite brighter haze or upper cloud layer seen at 315 and at 45 (not shown). 'Course this is also towards the London megalopolis. [There appears to be a darker layer towards the sun also, so I don't think these are image artifacts.] -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

I think I am starting to get SAS after watching the videos a few times.
And it was still less than 1/3 of the way up to space. Congrats on the successful mission. |
