Our Paper Aircraft Released Into Space (PARIS) programme continues to advance on multiple fronts, with the Vulture 1-X structure coming along nicely, a Mark 2 release mechanism ready for testing and our logistics team pondering just how to get the maximum bangs for bucks from launch day - when it finally arrives. As avid …
Good Job !!
That would be awesome to see the launch as well, or not to tempt fate the non launch :O
Long focal length telescope + piggyback camera
You can piggyback a camera onto the top of the telescope. This is pretty common, you use a big telescope for astrophotography and a second smaller scope strapped to the top with a webcam attached - if you're taking a 30 minute exposure, even an expensive motorised scope will drift slightly off target, you can correct it using the webcam view.
Note that you might need a bigger mount mind. And a second scope, one for visual tracking and one for the camera.
i love how this is coming along, cant wait to see this thing in all its glory on the drop day!
It has to be said......
.......capturing an A4 sheet of cardboard from 23,000 metres was a big ask, but it's hats off to Alejandro for this view.
Splendid stuff, job well done, give that man a pint!
Am I missing something?
"capturing an A4 sheet of cardboard from 23,000 metres was a big ask, but it's hats off to Alejandro for this view."
If you were looking for an A4 sized target against wall to wall blue sky it would surely be harder than finding a big pile of pipes first and then locating the target against them.
I'm not worried about Google surveillance anymore...
...but I'm now seriously concerned that Lester has access to a telescope.
[drawing the curtains]
It's not Lester with a telescope you should be worried about, it's that he works with Lewis...and Lewis knows people with some very big boats...
Big Brother because El Reg is watching you...
Colour me impressed
A sheet of A4 measures 0.21 * 0.297 m. At a distance of 23 000 m,. the long side is subtending an angle of just 0.013 milliradians.
More helpfully, about 2.7 arcseconds :) Or about 20x better than our own eyesight
Simple Baloon Release Mechanism
This is probably in the wrong area, but the proper one was closed.. An idea for a more simple, less mechanical, possibly more reliable release mechanism. A baloon in a clear glass or plastic tube, open to the atmosphere, a valve in the inflating end to pressurize, the baloon painted black at the other end to block light from an LED to a light sensor. When the baloon expands linearly along the tube to block the light path through or just outside the tube, it would cause an electro-magnetic latch to release the package. It would take some experimenting and calibration to find the proper size tube and baloon, and amount of pressure to make it work reliably... but, certainly more simple and less mechanical, possibly smaller and lighter, too.
This is just not going to work. A better way might be to attach a "corner cube" reflector and track it by aiming a wide beam laser at it. The corner cube will always return a signal in the exact opposite of the direction it receives it, so you can "ping" it with a broad beam and it will always ping back with a tightly focused beam. This method is is used on scientific experiments like the Lunar Laser Ranging Reflector from the Apollo missions, you can put corner cubes on the moon, ping it from earth, and get a signal return from 240k miles.
See, I can have good ideas sometimes.
From the last installment:
"Last but not least, I hope you can get a couple of nice telescopes to film this thing through. That or let any commentards know where and when with enough notice that they can bring theirs. This is daftness on a scale of painting a Robin Reliant up as a radio-controlled space shuttle and sending it heavenward on the most powerful non-commercial rocket built in Europe. It'd be a shame to not have a video of the fun."
Thanks for listening. ;)
.. but when's it going to launch?
We're an impatient lot, and you're heading towards missing any summer window before the 8 month UK winter cloud rolls over.... :)
I'm impressed he found the target...
...although that big red arrow must have made it easier.
A GPS indicates altitude, could you not use this signal for the release?
To those suggesting alternate release mechanisms
One of the stated objectives was that the release mechanism be as purely mechanical as possible.
@ M Gale
I hate to be a pedant (actually I quite like being a pedant) but it's a Reliant Robin, not Robin Reliant. Funny as the Top Gear episode was, you would not say Focus Ford would you?
