## FAQs
### Q: What was the purpose of Progress M-35?
A: Progress M-35 was an uncrewed cargo spacecraft designed to deliver supplies, fuel, and equipment to the Mir space station during its operational mission in 1997.

### Q: How long was Progress M-35 in orbit?
A: Progress M-35 remained in orbit for 94 days, from its launch on 5 July 1997 until its controlled re-entry on 7 October 1997.

### Q: Which rocket launched Progress M-35?
A: Progress M-35 was launched aboard a Soyuz-U rocket from Gagarin’s Start at the Baikonur Cosmodrome.

## Why It Matters
Progress M-35 played a critical role in sustaining the Mir space station during the late 1990s, a period when Russia’s space program faced severe budget constraints. By delivering essential supplies and propellant, the mission helped extend Mir’s operational life and supported continued scientific research in microgravity. The Progress-M series, including M-35, demonstrated the reliability of Russia’s automated cargo spacecraft, a legacy that later informed the design of cargo vehicles for the International Space Station. The mission also marked one of the final flights before Mir’s eventual decommissioning, symbolizing the transition from the Soviet-era space station program to international cooperation in space.

## Notable For
- One of the last Progress flights to Mir before its decommissioning
- Part of the long-running Progress-M series that began in 1989
- Flew during a financially challenging period for the Russian space program
- Used the standard Soyuz-U launch vehicle, highlighting the rocket’s versatility

## Body
### Mission Overview
Progress M-35 was launched on 5 July 1997 from Gagarin’s Start at the Baikonur Cosmodrome. The spacecraft was inserted into orbit by a Soyuz-U rocket, a launch vehicle that had been the workhorse of Soviet and Russian space programs since the 1970s. After a two-day rendezvous profile, M-35 docked with the Mir space station to deliver cargo.

### Spacecraft Details
As a Progress-M model, M-35 was an uncrewed, automated cargo vehicle derived from the crewed Soyuz spacecraft. It carried dry cargo, water, air, and propellant. The Progress-M series introduced upgraded avionics and improved docking systems over earlier Progress variants.

### Mission Timeline
- Launch: 5 July 1997
- Docking: within two days of launch
- Undocking: late September 1997
- Re-entry: 7 October 1997

After undocking, M-35 was deorbited over the Pacific Ocean, a standard procedure to ensure safe disposal of the spacecraft.

### Legacy
Progress M-35 was part of a continuous chain of cargo missions that kept Mir operational through the 1990s. Its successful flight reinforced the reliability of the Progress-M design, which continued to serve the International Space Station program after Mir’s deorbit in 2001.
