SpaceX's Falcon 9 is scheduled to launch at in a window between 18:27 and 20:57 EST (22:27 and 00:57 UTC) today. This is the fourth launch of Falcon 9 in 2017, and the 32nd launch of Falcon 9.
What is the mission?
Falcon 9 v1.2 will launch from Kennedy Space Center pad LC-39A to send SES-10 into a geostationary transfer orbit (GTO) for SES, a provider of secure satellite and ground communications solutions.
Reusability is here? It's finally happening, isn't it?
Yes it is. This is the most important launch in SpaceX's young history. It's the first time a previously launched first stage is going to be flown again. This is history in the making, a massive leap in space launch reusability compared to that shown by the Space Shuttle.
Where did this flown first stage come from?
The first stage being flown in this launch was the one previously recovered having launched in the NASA CRS-8 mission to resupply the International Space Station. This core, F9-33 made history itself by being the first rocket to land on a drone ship, which you can see here
What is the big picture here? Why is this such a big deal?
Sending stuff into space is super inefficient and costly. You spend millions into making a rocket to launch, throwing most of it away to burn up in the atmosphere to send a payload into orbit. The average cost to send one pound of anything to the International Space Station is $10,000, for example. By re-using part of your launch vehicle, like SpaceX are trying to do, it should and will reduce the cost of sending stuff into space. It opens up many possibilities for the commercial market by making things cheaper. The same theory of rocket reuse will eventually be used in sending humans to Mars - but that's a whooooole other story for some time in the future..
Will this reused first stage be attempting a landing?
Yes it will! Unlike the last mission to GTO, this launch profile and payload allows for the margins to attempt a landing. So the east coast drone ship "Of Course I Still Love You" will be stationed 646km downrange from the launch pad.
Where can I watch the launch?
As usual, you can watch SpaceX's coverage on Youtube with the Hosted Webcast or Technical Webcast
UPDATE!
Total mission success!
- The first stage, that had previously launched NASA's CRS-8 mission, successfully launched SES-10 and landed on "Of Course I Still Love You"
- Successful second stage deployment of SES-10 into geostationary transfer orbit.
Today was a good day.
