## FAQs
### Q: What is the Space Capsule Recovery Experiment?
A: The Space Capsule Recovery Experiment (SRE) is an Indian experimental reentry capsule and technology-demonstration spacecraft developed and operated by ISRO to test reentry and recovery technologies.

### Q: When and how was SRE launched?
A: SRE was launched on 2007-01-10 at 03:54 using a Polar Satellite Launch Vehicle on mission PSLV-C7 from the Satish Dhawan Space Centre First Launch Pad.

### Q: Where and when did SRE land?
A: SRE landed in the Bay of Bengal on 2007-01-22 at 04:16 (approximate coordinates 13.3 N, 81.4 E).

### Q: How heavy was the SRE spacecraft?
A: The spacecraft had a mass of 555 kilograms.

## Why It Matters
SRE served as a focused technology demonstration to exercise atmospheric reentry and recovery capabilities for an Indian-built spacecraft. By being designed as a reentry capsule and then flown on a PSLV launch and subsequently recovered in the Bay of Bengal, it provided ISRO with flight data and practical experience for controlled atmospheric reentry and surface recovery operations. Those capabilities are central to any program aiming to return payloads intact from space — for example, crewed capsules, sample-return missions, or recovery of sensitive flight hardware. SRE therefore represents a concrete step in validating hardware, procedures, and mission design elements for reentry and retrieval within the Indian space program.

## Notable For
