Editor's note: Rocket Lab has delayed the launch of its "There And Back Again" Electron booster recovery mission to no earlier than May 2 due to weather.
Rocket Lab will try to notch a huge and dramatic reusability milestone Monday (May 2), and you can watch it live.
The California-based company is scheduled to launch 34 satellites with its two-stage Electron rocket Monday from its New Zealand site during a two-hour window that opens at 6:35 p.m. EDT (2235 GMT). The mission plan includes an attempt to catch the Electron's falling first stage with a helicopter shortly after liftoff — something that's never been done before.
Sunday's mission, the 26th overall for Rocket Lab is called "There And Back Again" — a nod to the two-way journey the Electron first stage will make if all goes according to plan.
Rocket Lab is working to make Electron first stages reusable, as a way to decrease costs and boost launch cadences. The company settled on the helicopter strategy because Electron is too small to make propulsive, vertical touchdowns like SpaceX's Falcon 9 rockets do. Electron cannot carry enough fuel to have the required amount left over for landing burns, Rocket Lab representatives have said.
Rocket Lab has already brought several boosters down for controlled, parachute-aided ocean splashdowns, and it has snagged dummy boosters with a helicopter in a series of drop tests. But "There And Back Again" will break new ground: Rocket Lab has never tried a helicopter snag during an orbital launch before.
And we could get an up-close view of Sunday's historic try.
"We will attempt to show live footage of the helicopter capture during this mission, but we do expect some video loss due to the remote location of the helicopter during the capture attempt," Rocket Lab representatives wrote in an update.
The 34 satellites flying Sunday belong to a variety of customers, including Alba Orbital, Astrix Astronautics, Aurora Propulsion Technologies, E-Space, Spaceflight Inc. and Unseenlabs, Rocket Lab wrote in a mission description. Their successful deployment would bring the total number of satellites lofted by Electron to 146.
Editor's note: This story was updated at 3 p.m. EDT (1700 GMT) on April 29 with the new launch date for the mission: Rocket Lab pushed the liftoff from April 29 to May 1, citing weather issues.
