Rocket Lab plans to recover and re-fly the first stage of its Electron launch vehicle — this move aims to enable Rocket Lab to further increase launch frequency by eliminating the need to build a new first stage for every mission.
Work on Rocket Lab’s Electron first stage reuse program began in late 2018, at the end of the company’s first year of orbital launches. The plan to reuse Electron’s first stage will be implemented in two phases. The first phase will see Rocket Lab attempt to recover a full Electron first stage from the ocean downrange of Launch Complex 1 and have it shipped back to Rocket Lab’s Production Complex for refurbishment.
The second phase will see Electron’s first stage captured mid-air by helicopter, before the stage is transported back to Launch Complex 1 for refurbishment and relaunch. Rocket Lab plans to begin first stage recovery attempts in the coming year.
A major step towards Rocket Lab’s reusability plans was completed on the company’s most recent launch, the Make It Rain mission, which launched on 29 June from Launch Complex 1. The first stage on this mission carried critical instrumentation and experiments that provided data to inform future recovery efforts. The next Electron mission, scheduled for launch in August, will also carry recovery instrumentation.
Rocket Lab Founder and Chief Executive Peter Beck said reusing Electron’s first stage will enable the company to further increase launch frequency by reducing production time spent building new stages from scratch. From day one, Rocket Lab’s mission has been to provide frequent and reliable access to orbit for small satellites. Having delivered on this with Electron launching satellites to orbit almost every month, the company is now establishing the reusability program to further increase launch frequency,. Reusing the stage of a small launch vehicle is a complex challenge, as there’s little mass margin to dedicate to recovery systems. For a long time, Rocket Lab said the firm wouldn’t pursue reusability for this very reason; however, Rocket Lab has been able to develop the technology that could make recovery feasible for Electron. The firm is excited to put that technology into practice with a stage recovery attempt in the coming year.
For all involved in the satellite and space industry and the various market segments that add value to these dynamic environments, the 2020 SmallSat Symposium is truly worth your consideration for attendance.
The SmallSat Symposium is hosted by Satnews Publishers which, since 1983, has been a provider of a satellite news, media and events. This information packed forum was created to enable you and your company to secure a larger portion of market share as well as to take part in the next stages of your company's or organization's growth.
The personal connections at the SmallSat Symposium enable attendees to network with established organizations, subject-matter experts as well as 'New Space' entrants.
The SmallSat Symposium will focus on new technologies and the business environment that is shaping the implementation of smallsat constellations, smallsat launchers, the challenges facing the smallsat developer and actors as well as the enormous benefits of these advanced technologies that will benefit our world.
This event assembles more than 100 diverse speakers, all of whom possess deep industry experience. Additionally, numerous opportunities exist to mingle and network with peers while enjoying exceptional, complimentary meals and refreshment breakfast.
