Summary
IRDT 1 launched on a Russian Federal Space Agency (ROSCOSMOS) Soyuz-U-PVB from 31/6, Baikonur Cosmodrome, Republic of Kazakhstan on February 8, 2000. It was Russian Federal Space Agency (ROSCOSMOS)'s 98th launch, 3rd this year and humanity's 4,376th orbital launch attempt. It was the 54th Soyuz-U-PVB flight and the 1st this year. The payload was bound for low Earth orbit (LEO). Gruzovoy Maket, one of 2 catalogued objects, reached a 588 × 614 km orbit inclined 64.9°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
IRDT (Inflatable Re-Entry and Descent Technology) is a new technology to return payloads from orbit without a heavy heatshield and parachute system. A inflatable cone provides protection during reentry and a second inflatable extension of the cone reduces the speed further for a safe landing.
