## Summary
B1056 was a Falcon 9 Block 5 first-stage booster operated by SpaceX, notable for being destroyed during a landing failure on February 17, 2020, after completing four orbital launches. It was part of SpaceX's reusable rocket program, contributing to the company's efforts to lower the cost of access to space.

## Key Facts
- **Destroyed**: February 17, 2020, due to a hard landing failure after launching a Starlink mission.
- **Operator/Manufacturer**: SpaceX (United States).
- **Launches**: Four missions (SpaceX CRS-17, CRS-18, JCSAT-18/Kacific-1, and Starlink).
- **Class**: Falcon 9 Block 5, the current version of the Falcon 9 orbital launch vehicle.
- **Serial Number**: B1056 (preceded by B1055, followed by B1057).
- **Status**: Classified as a "former entity" after its destruction.

## FAQs
### Q: When was B1056 destroyed?
A: B1056 was destroyed on February 17, 2020, during a landing attempt following the launch of a Starlink mission.

### Q: How many launches did B1056 complete?
A: B1056 flew four successful missions before its destruction: CRS-17 (May 4, 2019), CRS-18 (July 25, 2019), JCSAT-18/Kacific-1 (December 17, 2019), and Starlink (February 17, 2020).

### Q: What made B1056 notable?
A: B1056 was notable for its role in SpaceX's reusable rocket program and for being the first Block 5 booster to fail landing after multiple reflights.

## Why It Matters
B1056 played a critical role in SpaceX's mission to demonstrate reusability, a cornerstone of its cost-reduction strategy for space access. While its destruction highlighted the risks of rocket recovery, the data gathered from its flights and failure contributed to iterative improvements in the Falcon 9 design. This booster exemplified SpaceX's "fail fast, learn faster" approach, where each mission—success or failure—advances the development of reliable reusable rockets. Its legacy underscores the challenges and innovations in sustainable spaceflight technology.

## Notable For
- **Four Launches**: Achieved four orbital launches before failure, demonstrating reusability potential.
- **Hard Landing Failure**: First Block 5 booster to be lost during recovery after multiple reflights.
- **Block 5 Membership**: Part of the upgraded Falcon 9 Block 5 series, designed for rapid reuse.
- **Preceded by B1055/Succeeded by B1057**: Part of a sequence of boosters used in SpaceX's heavy launch schedule.

## Body
### Launch History
- **CRS-17**: Launched on May 4, 2019, delivering cargo to the International Space Station.
- **CRS-18**: Flew on July 25, 2019, supporting another ISS resupply mission.
- **JCSAT-18/Kacific-1**: Deployed communications satellites on December 17, 2019.
- **Starlink**: Final mission on February 17, 2020, launching Starlink satellites before the booster's destruction.

### Fate
B1056 was lost during the Starlink mission's landing attempt on February 17, 2020, due to a "hard landing." The failure occurred after the booster experienced issues during its descent, preventing a successful recovery.

### Specifications
- **Class**: Falcon 9 Block 5 (current version of the Falcon 9).
- **Manufacturer/Operator**: SpaceX (United States).
- **Serial Number**: B1056 (preceded by B1055, followed by B1057).
