The mission

Sub-orbital launch under Rocket Lab’s Hypersonic Accelerator Suborbital Test Electron (HASTE) program, details TBD. Note: Despite reported as a strictly sub-orbital launch program, this launch was cataloged by the USSF to have left 2 rocket stages in a 200 km, 40° very low Earth orbit by the US Space Force. The payload was not cataloged and may have been deliberately de-orbited.

Type
Government/top secret
Destination

The rocket

Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage. It is also used as a suborbital testbed (called HASTE) for hypersonics research.

The operator

Rocket Lab

Rocket Lab is an American aerospace manufacturer with a wholly owned New Zealand subsidiary. The company develops lightweight, cost-effective commercial rocket launch services. The Electron Program was founded on the premise that small payloads such as CubeSats require dedicated small launch vehicles and flexibility not currently offered by traditional rocket systems. Its rocket, the Electron, is a light-weight rocket and is now operating commercially. The company is also producing a variety of spacecrafts and spacecrafts components.
