A student in Hokkaido that aims to become a universe with a balloon made at about 5000 yen, reaching an altitude of 7000 m

According to the story from a person currently studying in Hokkaido, "I wanted to read Gigazine's article on the universe with a balloon and want to try it myself, actually made a balloon and aimed at the universe" So I got a report that was pretty enthralled.

From the heavens Aiming for space shooting with a handmade balloon

"I wanted to shoot the balloon and shoot the universe, but I do not know what kind of equipment to make, I do not know how strong the wind is, I do not know what will happen after launch. "Since there was not any data, we designed various investigations by ourselves, we did not have any money so we devised it so that it could be cheap and completed with about 5000 yen with a camera.It also a simple mechanism to slow down the falling speed I took in the idea. "


"First, attach a string, try not to let the balloon run off"



The first one was launched at 13:21 on October 8, 2011 in Kita Ward, Sapporo city, the weather is clear and sunny.





"There was also a failure, but it was found that the required difference in amount of helium was greatly different than the calculated value, the place where strength is required by the balloon, the ideal camera attachment position, etc. was found," and the result was 300 meters in height It has reached.


The second time is 11:48 on October 29, 2011 at 11:48 after 11 days, it is sunny, 1 meter from the eastern wind. "I lost a balloon and a set of observation instruments in an experiment that I did on a windy day a few days after the first experiment.The picture at that time was lost with the balloon and I can not introduce it here. The reason for the cord was that the knot of the cord was broken, I regretted this failure, redesigned the balloon and made changes to reduce the number of knots. "





"Also, from the first experiment, we decided to use a huge balloon with a diameter of 76 cm because we found that vibrations were intense and videos could not be taken well when using a small amount of small balloons in the balloon, and we also decided to position the camera I changed from downward to true landscape to get a wider view. "


"With the tied balloon, the limit that can be raised is restricted by the string, so we aimed 500 meters. The tied balloon is the last in this."


And the third time is November 10, 2011 at 11:16 am, the weather is clear and sunny, the sky is launched from the north wind, East Sapporo City.






"Based on the results of the first and second experiments, we redesigned the new balloon and made a launch to observe the universe. As a result it did not rise to the stratosphere and it fell at about 7000 m, but from Sapporo to Muroran I flew a long distance and succeeded in showing various scenes.The picture is arranged in the order of the landscape photographed by the balloon from the preparation, in the order of the drifted route "







According to Talekomi's e-mail "Unfortunately I could not go up to the height where the universe could be seen, but I was able to take various photos such as the cityscape of Sapporo that goes away, Lake Shikotsu from the sky, panorama overlooking Mt. Yotei. The balloon carrying the 180 km long journey, the kind person picked up, I came home. "



"Since the winter has come in 2011, the experiment is a pause until the following year when the weather becomes calmer. Based on the experiences and data from previous experiments, further improvements were made, and the wind in the summer of 2012 is calm I will take a picture of the boundary between the universe and the atmosphere ", and the challenge to the universe will continue further.
