## FAQs
### Q: What is BATSAT?
A: BATSAT is a satellite (recorded as a former spacecraft) that was launched on 1998-02-26 and later reentered the atmosphere on 2000-10-09. It is also known by the aliases Teledesic 1 and T1.

### Q: When and how was BATSAT launched?
A: BATSAT was launched on 1998-02-26 at a recorded time of 07:07. The launch used a Pegasus F20 vehicle and lists "Stargazer" with Vandenberg Space Force Base as the start point; the launch contractor was Orbital Sciences Corporation.

### Q: What happened to BATSAT after launch?
A: BATSAT is recorded as a former spacecraft and underwent atmospheric entry (reentry) on 2000-10-09.

### Q: How can BATSAT be identified in catalogs or databases?
A: BATSAT’s COSPAR ID is 1998-012B and its Satellite Catalog Number (SCN) is 25234. External identifiers include a Google Knowledge Graph ID (/g/11b6f06c_t) and a Wolfram Language entity code Entity["Satellite", "25234"].

## Why It Matters
BATSAT represents a specific late-1990s small-satellite mission that illustrates the use of air-launched rockets for placing spacecraft into orbit. Its recorded aliases (Teledesic 1, T1) tie it to naming conventions used for networked satellite projects of that era, and its Pegasus F20 launch highlights the operational role of air-launched Pegasus vehicles and their associated start-point procedures (listed here as "Stargazer" and Vandenberg Space Force Base). The documented reentry on 2000-10-09 marks the end of its on-orbit lifetime and places BATSAT in historical records used for cataloging spacecraft lifetimes and launch outcomes. For researchers, historians, or data curators, BATSAT serves as a verifiable data point with standard catalog identifiers (COSPAR ID, SCN) and primary launch metadata (date, vehicle, contractor, start point), which supports studies of launch vehicle usage, mission timelines, and satellite fleet histories from the late 1990s.

## Notable For
- Being launched on a Pegasus F20 air-launched rocket with start point listed as "Stargazer" at Vandenberg Space Force Base.  
- Alias usage as Teledesic 1 (T1), indicating its naming within a Teledesic-related series.  
- Having a clear catalog identity: COSPAR ID 1998-012B and Satellite Catalog Number 25234.  
- Recorded atmospheric entry (reentry) on 2000-10-09, marking its documented end of mission.  
- Launch conducted by Orbital Sciences Corporation as the launch contractor.
