## Why It Matters  
Progress M1‑4 represents a key node in Russia’s long‑standing tradition of automated cargo delivery to orbital outposts. By delivering essential provisions, scientific equipment, and propellant, the spacecraft helped sustain continuous human presence aboard the space station it serviced, reducing the need for crewed resupply flights and lowering operational costs. Its successful launch and controlled re‑entry demonstrated the reliability of the Soyuz‑U launch system and the Progress‑M1 design, reinforcing confidence in Russia’s autonomous logistics capabilities during a period of intensive international cooperation on the International Space Station. The mission’s short, well‑documented timeline also provides valuable data on orbital decay dynamics for low‑Earth‑orbit payloads.  

## Notable For  
- First Progress‑M1 mission launched in late 2000, marking continued use of the series after the Mir era.  
- Utilised the Soyuz‑U rocket, a versatile workhorse of the Soviet/Russian launch fleet.  
- Executed a precise atmospheric re‑entry on 8 February 2001, showcasing controlled disposal of cargo spacecraft.  
- Served as a bridge between the older Progress M1‑3 and the newer Progress M‑44, illustrating the evolution of Russian cargo spacecraft.  

## Body  

### Overview  
Progress M1‑4 belongs to the Progress‑M1 class, a subset of the broader Progress series used for uncrewed resupply of Russian space stations. The spacecraft is built on a modular design that combines a pressurized cargo module with a propulsion module for orbital maneuvering and de‑orbit burns.

### Launch Details  
- **Date & Time:** 16 Nov 2000 (UTC)  
- **Launch Site:** Gagarin’s Start, Baikonur Cosmodrome, Kazakhstan  
- **Rocket:** Soyuz‑U, a reliable variant of the Soyuz family  
- **COSPAR ID:** 2000‑073A  

The launch proceeded without anomalies, placing the spacecraft into a low‑Earth orbit aligned with the target station’s orbital plane.

### Mission Profile  
- **Primary Objective:** Deliver supplies, scientific payloads, and propellant to the orbiting station.  
- **Duration:** Approximately 84 days in orbit before de‑orbit.  
- **Operations:** Docked autonomously using the Kurs rendezvous system, transferred cargo, and later performed a de‑orbit burn.  

### Orbit and Decay  
- **Orbit:** Low‑Earth orbit, typical of Progress missions (≈ 400 km altitude, 51.6° inclination).  
- **Re‑entry:** Atmospheric entry occurred on 8 Feb 2001, resulting in the spacecraft’s destruction over a remote area, as per standard disposal procedures.  

### Related Vehicles  
- **Predecessor:** Progress M1‑3 – another cargo mission in the same series.  
- **Successor:** Progress M‑44 – continued the resupply chain with updated systems.  
- **Launch Vehicle Family:** Soyuz‑U, a universal rocket variant employed for a wide range of payloads.
