HASTE Program Background

HASTE (Hypersonic Accelerator Suborbital Test Experiment) is Rocket Lab's suborbital launch services program, specifically designed for hypersonic research and scientific experiments. Compared to traditional sounding rockets and hypersonic test facilities, HASTE offers lower cost and higher frequency access to suborbital flight, providing longer microgravity experiment time and higher altitude than conventional approaches.

The Bubbles mission designation corresponds to a specific scientific experiment, with further details available through official mission pages. Rocket Lab continues to expand the Electron rocket's mission adaptability—from commercial satellite deployment to suborbital research experiments—demonstrating the flexibility of small launch vehicles in the scientific research launch sector.

Launch Details

Wallops Flight Facility

Wallops Flight Facility, located in Virginia, USA, is a NASA Goddard Space Flight Center launch facility primarily supporting NASA, state agencies, and commercial companies for suborbital and sounding rocket missions. Situated near the Atlantic coast, the facility offers favorable safety and monitoring conditions for various high-altitude balloon and small rocket experiments.

Rocket Lab Electron Rocket Overview

Electron is a small launch vehicle developed by Rocket Lab, primarily used for delivering small satellites to low Earth orbit (LEO). The rocket's first stage employs nine Rutherford engines, while the second stage uses a single vacuum-optimized Rutherford engine. To date, Electron has conducted multiple flight missions and serves as the primary launch system for Rocket Lab.

HASTE missions utilize a modified Electron configuration with a specialized upper stage or altered flight profile to meet suborbital research flight requirements.
