Today, SpaceX launched a Falcon 9 rocket carrying a Dragon supply capsule to the ISS.
Replay of launch below.
(Skip forward to 15 minutes for the launch, and 32 minutes for the deployment of the solar panels and a spectacular sunrise)
During this flight, SpaceX will attempt the precision landing of a Falcon 9 first stage for the first time, on a custom-built ocean platform known as the autonomous spaceport drone ship. While SpaceX has already demonstrated two successful soft water landings, executing a precision landing on an unanchored ocean platform is significantly more challenging.
The odds of success are not great—perhaps 50% at best. However this test represents the first in a series of similar tests that will ultimately deliver a fully reusable Falcon 9 first stage.
Early reports are that it made it down, but a landed hard.
Still an impressive show.
