HASTE | Curveball
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.
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.
