## Summary  
Soyuz TM-30 was the 39th crewed spaceflight to the Mir space station, launched in 2000. It was part of Russia's Soyuz programme and carried two cosmonauts to conduct maintenance and research on Mir. The mission marked one of the final expeditions to the aging station before its decommissioning.

## Key Facts  
- **Launch Date**: April 4, 2000, from Baikonur Cosmodrome ("Gagarin's Start").  
- **Landing Date**: June 16, 2000, in Kazakhstan.  
- **Crew**: Sergei Zalyotin (commander) and Aleksandr Kaleri (flight engineer).  
- **Spacecraft**: Soyuz-TM (fourth generation Soyuz).  
- **Launch Vehicle**: Soyuz-U rocket.  
- **Duration**: 72.8 days (~6.29 million seconds).  
- **Orbits Completed**: 1,145 in low Earth orbit (orbital altitude: 358–384 km).  
- **Preceded by**: Soyuz TM-29 (1999).  
- **Followed by**: Soyuz TM-31 (first ISS mission).  
- **Operator**: Roscosmos State Corporation.  

## FAQs  
### Q: What was the purpose of Soyuz TM-30?  
A: It delivered crew and supplies to Mir for maintenance and scientific experiments, extending the station's operational life.  

### Q: Who were the crew members?  
A: The mission included Sergei Zalyotin as commander and Aleksandr Kaleri as flight engineer.  

### Q: How long did Soyuz TM-30 stay in orbit?  
A: The mission lasted 72.8 days, completing 1,145 orbits around Earth.  

## Why It Matters  
Soyuz TM-30 was pivotal in maintaining Mir, then the only operational space station, bridging the gap before the International Space Station (ISS) became fully operational. The mission demonstrated Russia's commitment to sustaining Mir despite financial challenges and aging infrastructure. It also provided critical data on long-term space habitation, informing future ISS operations. The crew's work included repairs and experiments, preserving Mir's scientific legacy before its controlled deorbit in 2001.  

## Notable For  
- One of the final missions to Mir before its decommissioning.  
- Used the Soyuz-TM spacecraft, a reliable workhorse of Russian spaceflight.  
- Contributed to understanding microgravity effects on aging spacecraft systems.
