Q: What is Capella‑11?

**A:** Capella‑11 is a synthetic‑aperture‑radar satellite built and operated by the U.S. company Capella Space, designed to capture high‑resolution radar imagery of Earth’s surface.

Q: When and how was Capella‑11 launched?

**A:** It launched on 23 August 2023 aboard Rocket Lab’s Electron launch vehicle from Rocket Lab Launch Complex 1 in New Zealand.

Q: What role does Capella‑11 play in the Capella‑SAR constellation?

**A:** Capella‑11 follows the earlier satellite Capella‑10 and precedes Capella‑13, expanding the constellation’s imaging capacity and providing more frequent SAR coverage for commercial and governmental customers.

Q: Who operates Capella‑11 and what is its primary purpose?

**A:** Capella Space operates the satellite, using its SAR payload to deliver all‑weather, day‑and‑night Earth observation data for applications such as disaster monitoring, infrastructure mapping, and defense intelligence.

Q: What is synthetic‑aperture radar?

**A:** Synthetic‑aperture radar (SAR) is a radar imaging technique that synthesises a large antenna aperture from the motion of the satellite, enabling high‑resolution images regardless of cloud cover or lighting conditions.
