Paz

Spain's first radar reconnaissance satellite, Paz is an X-band SAR spacecraft operated by Hisdesat at the same orbital altitude as Germany's TerraSAR-X and TanDEM-X to form a three-satellite SAR constellation with improved revisit times.

The mission also carried Tintin A and Tintin B, SpaceX's first two Starlink prototype satellites. A newly designed payload fairing debuted on this flight, and SpaceX attempted for the first time to catch a returning fairing half with the recovery vessel Mr. Steven — the fairing narrowly missed the ship but achieved a soft water landing.
