## FAQs  
### Q: When was Progress M1‑1 launched?  
**A:** Progress M1‑1 was launched on 1 February 2000 from Gagarin’s Start aboard a Soyuz‑U rocket.  

### Q: What was the purpose of Progress M1‑1?  
**A:** As a member of the Progress‑M cargo series, Progress M1‑1 was used to deliver supplies and equipment to a Russian‑operated space station.  

### Q: Which spacecraft followed Progress M1‑1 in the series?  
**A:** Progress M1‑2 succeeded Progress M1‑1 as the next Russian cargo spacecraft in the sequence.  

### Q: How long did Progress M1‑1 stay in orbit?  
**A:** The spacecraft remained in orbit for about 85 days, re‑entering the atmosphere on 26 April 2000.  

### Q: What launch vehicle was used for Progress M1‑1?  
**A:** The mission employed a Soyuz‑U launch vehicle, a variant of the Soviet‑era Soyuz rocket family.  

## Why It Matters  
Progress M1‑1 exemplifies the continuous, automated logistics chain that underpins long‑duration human presence in orbit. By delivering food, fuel, and scientific equipment without crew, the Progress‑M series reduces the need for manned resupply flights, lowering operational risk and cost. The 2000 mission contributed to the reliability record of Russian cargo spacecraft, supporting the ongoing operation of space stations and enabling international collaboration in low‑Earth orbit. Its successful launch, orbital operations, and controlled re‑entry demonstrate the mature engineering of the Soyuz‑U launch system and the Progress‑M platform, both of which remain cornerstones of space‑flight infrastructure.

## Notable For  
- First Progress‑M spacecraft launched in the year 2000.  
- Utilized the Soyuz‑U rocket, a versatile workhorse of the Soviet/Russian launch fleet.  
- Assigned the COSPAR identifier 2000‑005A and catalog number 26067, linking it to global tracking databases.  
- Served as a bridge between the earlier Progress M‑42 and the later Progress M1‑2 missions, marking continuity in the cargo program.  
- Completed a full mission cycle—from launch to atmospheric entry—in just under three months.

## Body  

### Overview  
Progress M1‑1 belongs to the **Progress‑M** class, a series of unmanned cargo spacecraft designed to resupply Russian‑operated space stations. The class is specifically built for delivering consumables, propellant, and scientific payloads while also providing the capability to boost the station’s orbit.

### Launch Details  
- **Date & Time:** 1 February 2000.  
- **Launch Site:** Gagarin’s Start (Baikonur Cosmodrome).  
- **Vehicle:** Soyuz‑U, a universal variant of the Soyuz rocket family.  
- **Mission Type:** Cargo delivery (rocket launch event recorded at Gagarin’s Start).  

### Orbital Life & Decay  
- **Orbit Insertion:** Achieved shortly after launch; exact orbital parameters not listed in source.  
- **Mission Duration:** Approximately 85 days.  
- **Atmospheric Entry:** 26 April 2000, marking the end of the spacecraft’s operational life.  

### Classification & Lineage  
- **Instance of:** Progress‑M (cargo spacecraft).  
- **Predecessor:** Progress M‑42, another Russian cargo vehicle.  
- **Successor:** Progress M1‑2, continuing the series’ resupply role.
