A Helicopter Will Try to Catch a Rocket This Week

Southern California-based Rocket Lab builds and launches a variety of aerospace equipment, but its claim to fame is a reusable small launch vehicle called Electron. Just 18 meters tall, this two-stage rocket booster is made to deliver small satellites either individually or as “rideshare,” or multiple satellites at a time. It’s the only reusable orbital-class rocket currently in use; the only rocket that comes close is SpaceX’s Falcon 9, which is designed to launch up to ten times but stands over 70 meters tall.

In order to actually reuse Electron, Rocket Lab needs to be able to recover it before it sustains water damage from landing in the ocean. That’s where tomorrow’s mission comes in. Two and a half minutes after lifting off from Pad A at Launch Complex 1 on New Zealand’s Māhia Peninsula, Electron’s two stages will separate. The first stage will then be allowed to fall at 5,150 miles per hour, reaching temperatures of around 4,352 degrees Fahrenheit. Two parachutes will deploy at about eight and four miles respectively, after which a helicopter pilot will be responsible for capturing the parachute line with a hook.

Once Electron is (hopefully) brought safely back to land, Rocket Lab will inspect the rocket booster to determine its suitability for reflight. Rocket Lab has used imitation devices to conduct test runs of the recapture mission before but has never attempted to grab a real launch vehicle out of the air.

Tomorrow’s mission won’t just be an experiment, though. Electron’s first stage will deploy 34 payloads from a handful of commercial operators (Alba Orbital, Astrix Astronautics, Aurora Propulsion Technologies, E-Space, Unseenlabs, and Swarm Technologies), bringing its total satellite launch count up to 146.

“Trying to catch a rocket as it falls back to Earth is no easy feat, we’re absolutely threading the needle here, but pushing the limits with such complex operations is in our DNA,” said Peter Beck, Rocket Lab’s founder and CEO, in a statement. “We expect to learn a tremendous amount from the mission as we work toward the ultimate goal of making Electron the first reusable orbital small sat launcher and providing our customers with even more launch availability.”

NASA Will Soon Have a Helicopter on Mars

NASA's Perseverance rover will land on the red planet in about a month, but the rover won't be the only newly arrived robotic explorer. The wheeled robot carries the Mars Helicopter Ingenuity on its belly, and NASA has posted a handy list of things to know about this mission.

NASA Prepares to Deploy Mars Helicopter

The Ingenuity helicopter is attached to the underside of the rover, but it won't be for long. NASA just took the first step toward getting it airborne.

NASA’s Mars Helicopter Remains Grounded Awaiting Software Fix

NASA previously said the Ingenuity helicopter would take to the Martian skies over the weekend, but the agency announced late Friday that liftoff was delayed until at least April 14 because of a software issue.

NASA’s Ingenuity Helicopter Takes Flight on Mars

This marks the first time a human-made machine has taken flight on another planet. It's onward and upward from here.
