SpaceX footage of the Grasshopper vertical takeoff and landing test vehicle making its first roughly 6-foot hop in McGregor, Texas, on September 21, 2012. It was an early step toward a reusable Falcon 9 first stage.

Why Hacker News points people here: HN references it as the first Grasshopper test flight, a milestone in the history of reusable rockets.

(Resubmission of link . I rarely resubmit, but this really is HN material and warrants quality discussion)

I upvoted this thinking it was a new test, but sadly this is an older result from two months ago. To make amends for upvoting without reading the article, here is the history of Grasshopper's public flights Date Altitude Duration Youtube 2012-09-21 1.8 m 3 seconds this video 2012-11-01 5.4 m 8 seconds link 2012-12-17 40 m 29 seconds link 2013-03-07 80 m 34 seconds link 2013-04-17 250 m 61 seconds link 2013-06-14 325 m 68 seconds link

“The test platform was first hopped in 2012, only 8 years ago.”

First hop of landing test platform in 2012.

Very few rocket launches end with any kind of soft landing, let alone main boosters. Soft-landing a small payload, or in the case of the shuttle, a winged reentry vehicle, is the exception. (And yes, the Shuttle also soft-ish watered its SRBs underr chutes.) Retrorocket-soft-landing intact boosters from production launches fully upright was science fiction until four years ago. link The test platform was first hopped in 2012, only 8 years ago. this video (I'm not a Musk fanboi,I thought the powered landing was nuts, he proved me wrong.)
