SpaceX launches their 'Falcon Heavy" for the second time. This rocket is about as powerful as the space shuttle. Their first time launching failed to land the center rocket. They landed the two outer first stages. This second time, they landed all three. The rocket launches around 19:50, the two side stages land around 27:30, and the center core, well, the video feed gets rocked, and you don't get to see it. Also, While you can skip to the times all these happen, I'd think it would be more fun to watch the whole rocket launch, see the rockets in outer space, and watch them come back down the whole way; but, that's just me!
By landing the rockets, and reusing them, SpaceX(and Blue Origins, SpaceX's Amazon competitor) can bring the cost of space access way down. SpaceX has chosen not to continue working on making the second and third stages recoverable, choosing instead to recover the second stage of their Saturn V size rocket - Big Falcon Rocket. Actually, they've renamed it; but, I'm forgetting what that's called right now.
Of further significance of the landing of all three first stages of the Falcon Heavy here, SpaceX's third Falcon Heavy launch will launch the Planetary Societies Solar Sail. I'm not sure if they plan on sending it out throughout the solar system; or, if they are just going to test it in orbit. The Japanese have already sent a Solar Sail to Venus. A Solar Sail can make for perpetual solar system travel; they're a bit like Sailing ships, only for outer space. They can use the suns solar energy to accelerate to pretty much any part of the solar system.
