Rocket Lab suffers anomaly during launch, Earth-observation satellite lost (2024)

Rocket Lab suffered an anomaly during the launch of a radar Earth-observation satellite early Tuesday morning (Sept. 19).

An Electron rocket carrying a synthetic aperture radar (SAR) spacecraft for the California company Capella Space lifted off from Rocket Lab's New Zealand site Tuesday at 2:55 a.m. EDT (0655 GMT; 6:55 p.m. local New Zealand time).

The Electron's two stages separated as planned about 2.5 minutes after launch. But something went wrong shortly thereafter, ending the flight.

Rocket Lab's telemetry data, which the company provided during the livestream of Tuesday's launch, showed the velocity of the rocket's upper stage decreasing shortly after its single Rutherford engine was supposed to kick on.

The upper-stage engine may therefore have suffered an ignition failure or a premature shutdown, though that's just speculation. Rocket Lab did not identify a proximate or ultimate cause, saying in a post on X (formerly Twitter) that it will provide more information as it becomes available.

Tuesday's mission, which the company called "We Will Never Desert You," was its ninth of the year and 41st overall. The anomaly broke a string of 19 consecutive successful launches; the company's most recent failure had been in May 2021.

"We Will Never Desert You" aimed to deliver one of Capella Space's "Acadia" satellites to a circular orbit about 395 miles up (635 kilometers) above Earth. Tuesday's flight was the second in a four-launch contract to send these advanced SAR satellites skyward.

The first mission under that contract, Aug. 23's "We Love the Nightlife," featured an Electron with one used first-stage engine. (Electron's first stage is powered by nine Rutherfords.) That was a big milestone for Rocket Lab, which is working to make the booster reusable.

The company also recovered the Electron first stage on "We Love the Nightlife," after bringing it down softly for a parachute-aided ocean splashdown. "We Will Never Desert You" apparently did not involve a preflown engine, nor was a rocket recovery attempt in the cards; Rocket Lab did not mention such plans ahead of the launch or during the webcast.
