As you remember, on April 12, on Cosmonautics Day, our small server successfully into the stratosphere! During the flight, the server on board the stratospheric balloon distributed the Internet, filmed and transmitted video and telemetry data to the ground.
In a little over an hour, our web server flew to a height of 22700 meters, flew 70 km, experienced a temperature drop from +25 0Π‘ to -60 0Π‘, and received 125 messages from the habrazhites. Different messages came to the stratosphere: romantics confessed their love, offended equity holders asked to intercede for them, animal lovers were looking for cats and dolphins at an altitude of 22 kilometers, there was advertising, but how could it be without it. Greetings and congratulations on the Day of Cosmonautics came from Belarus, Ukraine, the Urals, Siberia, Sakhalin, Novorossiysk, Yaroslavl, Gomel, Bryansk.
Π publication, we summed up the results of the project, showed a small online recording from the probe and promised to show the full video of the flight. We present video recordings from two onboard cameras with all messages received from you, current altitude and coordinates on monitors.
A little background and useful links, for those who missed everything:
- Post about into the stratosphere (which we encountered in practice during launch).
- How did we do"Β» of the project - for lovers of geek porn, with details and code.
- a project where it was possible to monitor the movement of the probe and telemetry in real time.
- space communication systems that we used in the project.
- Text launch the server into the stratosphere.
- experiment
In one of the previous posts about the launch wanted to learn about how sound changes in the stratosphere, so we decided not to put music on these videos, listen, enjoy the silence and the wind.

During the flight of the server, we held a competition among Habr users, in which it was necessary to guess the place where the probe landed. More than 600 habrazhiteley took part in the competition.
Vlad was the closest , he guessed the point with an accuracy of 1 kilometer. Vlad won our main prize - a trip to Baikonur, we are preparing documents for sending him to the launch of the Soyuz manned spacecraft on July 20 and are waiting for a reporting post about the trip.
Second place - , his forecast was slightly less accurate, 3 km from the landing site. He has already received his prize in our office, congratulations and we wish you a pleasant trip.
20 winners were removed from 4 to 12 kilometers from the landing site of the probe. We are waiting for you on an excursion to Star City in May. For those who have not responded to our messages, please contact us as soon as possible in our or write in a personal on HabrΓ©.
