More about the project.

The team continues to actively work on stratospheric aerostats.

Recently, we completed tests of the latex envelope: 18 hours and 15 minutes of stable pressure with a drop of only 8 Pa/hour. An excellent result—the airtightness is confirmed, and the material holds.

Simultaneously, tests are being conducted on a new envelope with a volume of 500 cubic meters—more compact but functionally important.

The goal is to verify the overall stability of the structure, as well as to work through the entire cycle:
• bringing the envelope out of the hangar
• launching the vehicle
• dropping the payload

Tests of high-pressure cylinders that we will use in future missions are underway.

The tests being conducted, data collection, and new solutions—all this brings us closer to stable operations at altitudes up to 15–20 km.

*The translation was carried out with the assistance of artificial intelligence.
