SpaceX Rocket Splashes Down During Failed Landing Attempt

A new video gives an amazing rocket’s-eye view of a SpaceX booster’s unsuccessful bid to return to terra firma today (Dec. 5).

“Grid fin hydraulic pump stalled, so Falcon landed just out to sea. Appears to be undamaged & is transmitting data. Recovery ship dispatched,” Musk said via Twitter today.

Hypersonic grid fins help the booster steer its way back for a precision touchdown. Each Falcon 9 first stage sports four of these waffle-iron-looking things, which are installed close to the booster’s base.

Falcon 9 first stages don’t have backup systems to bail out malfunctioning grid-fin pumps, though that will probably change in the future, Musk said in another tweet.

“Pump is single string. Some landing systems are not redundant, as landing is considered ground safety critical, but not mission critical. Given this event, we will likely add a backup pump & lines,” he tweeted.

Is there one pump for all fins (Presumably with backup).

Musk also addressed the video dropout in another tweet, calling the webcast cutaway a mistake. “We will show all footage, good or bad,” he added.
