BAIKONUR, Kazakhstan (Roscosmos PR) — Proton-M carrier rocket with the Briz-M booster successfully launched from pad No. 39 of Site No. 200 at the Baikonur Cosmodrome.

The rocket carried two Russian telecommunication satellites Ekspress-80 and Ekspress-103 built by ISS Reshetnev company (part of Roscosmos). The launch and flight of the carrier rocket went nominally.

According to the flight sequence, 587 seconds after the liftoff the space head unit (booster and two spacecraft assembly) nominally separated from the third stage of the carrier rocket.

Further injection into orbit will be ensured by the booster service propulsion system. The total injection time from the liftoff and second satellite separation will reach 18 hours, 16 minutes and 40 seconds.

Proton-M carrier rocket is manufactured by Khrunichev Center (part of Roscosmos) and has been used to inject payloads into target orbits and departure trajectories as part of federal and commercial programs since 2001.

Throughout its operation, the rocket has undergone four deep modernizations allowing substantial improvement of its thrust to weight ratio and ecological characteristics while injecting heavy single and dual payloads.

ESA Reports Promising Progress for ExoMars Parachutes

A series of clips from different angles and at different speeds showing parachute extraction tests using a NASA/JPL test rig powered by compressed air.  The lid of the parachute assembly is pulled along a suspended cable at high speed while the end of the assembly is fixed to a wall. When the release mechanism is activated, the parachute bag is pulled away from the parachute at the target speed, mimicking the extraction as it will be on Mars. At the highest speeds, the tests enable the extraction to take place at more than 200 km/h.

PARIS (ESA PR) — A series of ground-based tests designed to check the extraction of the ExoMars 2020 mission’s parachutes from their bags have started successfully with promising results to keep the mission on track for next year’s launch.

Landing on Mars is a high-risk endeavour with no room for error. In just six minutes, a descent module with its precious cargo cocooned inside has to slow from around 21 000 km/h at the top of the planet’s atmosphere, to a soft landing at the surface controlled by the lander’s propulsion system.

BAIKONUR, Kazakhstan, August 5, 2019 (Roscosmos PR) — The Proton-M heavy-class carrier rocket launched at 21:56 UTC on August 5, 2019 successfully put Russia’s Ministry of Defence spacecraft into the intended orbit.

The launch of the carrier rocket and injection of the satellite into orbit using the Briz-M booster went as planned. The spacecraft was taken under control by the Titov Main Test and Space Systems Control Centre of the Russian Space Forces.
