"Catch Me If You Can"

Electron launched MATS, a Swedish satellite built to map waves in the mesosphere, the layer of the atmosphere above the stratosphere.

The flight also carried Rocket Lab's second attempt to catch an Electron first stage in mid-air with a helicopter. Telemetry from the stage dropped out during reentry and was not regained in time, so the helicopter was kept out of the recovery zone. The stage splashed down under its parachute and a ship went to collect it.
