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.

Rocket Lab launches satellite for U.S. Space Force Victus Haze responsive space exercise

VICTUS HAZE will see Rocket Lab design, build, launch, and operate a rendezvous proximity operation (RPO) capable spacecraft. U.S. Space Force Space Systems Command (SSC)’s Space Safari’s VICTUS HAZE mission will be an exercise of a realistic threat-response scenario and on-orbit space domain awareness (SDA) demonstration. Once the spacecraft build is complete, Rocket Lab will be entered into a Hot Standby Phase awaiting further direction. Once the exercise begins, Rocket Lab will be given notice to launch the spacecraft into a target orbit. After reaching orbit, the spacecraft will be rapidly commissioned and readied for operations. Rocket Lab will configure a Pioneer class spacecraft bus to meet the unique requirements of the VICTUS HAZE mission.

The mission will improve Tactically Responsive Space (TacRS) processes and timelines, demonstrating the ability to respond to on-orbit threats on very short timelines and validating techniques for space domain awareness (SDA) and on-orbit characterization. Rocket Lab’s constellation-class production capability and discriminating technical capabilities in the areas of in-space propulsion, precision attitude control, low latency communications, and autonomous operations are key enablers for this mission.

JAXA to launch tech demo satellites on Electron rockets

JAXA-manifested rideshare of eight separate spacecraft that includes educational small sats, an ocean monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna that can be packed tightly using origami folding techniques and unfurled to 25 times its size.

The satellites were originally planned to launch with RAISE-4 on a Japanese Epsilon-S rocket, but the Epsilon-S was heavily delayed due to test firing failures.

The 8 satellites are:

* MAGNARO-II
* KOSEN-2R
* WASEDA-SAT-ZERO-II
* FSI-SAT2

LOXSAT 1 is a demonstration satellite of a complete cryogenic oxygen fluid management system in orbit, developed by Eta Space and sponsored by NASA's Tipping Point program.

The system will be integrated on a Rocket Lab Photon-LEO satellite bus and collect critical cryogenic fluid management data in orbit for 9 months, demonstrating capabilities of in-space cryogenic storage and transferal. Eta Space plans to use technology developed for this mission to develop a truly commercial depot intended to serve multiple customers in the future.
