A Vacuum Chamber to Realize the Man-made Shooting Star Project
As a specialist manufacturer of vacuum pumps and vacuum system, Osaka Vacuum, Ltd. always focuses on satisfying customers' requirements for vacuum technology.
In September, 2016, Osaka Vacuum successfully completed a vacuum chamber (in size of W2 x D3 x H2 meters) for man-made shooting stars project and delivered it to a Tokyo-based firm ALE Co., Ltd. (ALE).
Meteors are one of most awe-inspiring nature phenomena. It is commonly known as name of “a shooting star” when a small dust or rock from space travels through the Earth’s atmosphere at high speeds, burns up to emit a glow of light, and be observed at night. ALE aims to recreate such phenomenon by releasing centimeter-sized particles into space from a meteor release device equipped on a satellite to generate shooting stars.

In development of the "meteor release device" which releases these particles into space, a vacuum chamber is required to test the device's performance on Earth, such as control of releasing speed, position and direction.

In order to produce an optimal vacuum chamber for testing the meteor release device for shooting stars project, we had a series of meetings to ensure that the required condition and performance would be met by the vacuum chamber produced. After delivery, the vacuum chamber was used to simulate the close state as in space and to conduct sufficient release experiments, which contributed to confirm the reliability and safety of the "meteor release device".
Our vacuum chamber has received a high evaluation from ALE for its ability to continuously maintain medium-low vacuum conditions and meanwhile, to meet such strict test requirements.

The man-made shooting stars can be created at any desired place in the world for various needs, such as live events or sports events. It will be visible for people within a 200-kilometer radius to enjoy the great "space entertainment" together.
