SpaceX will attempt the launch of EchoStar 105/SES-11 at 6:53 PM EDT (10:53 PM UTC). This is SpaceX's second launch attempt in 3 days, following the successful launch of 10 satellites for Iridium on Monday:

It's the third time SpaceX has used one of its landed boosters for a second flight — and if it sticks the landing again, it'll also be the third to have come safely back to Earth for a second time. The first reused Falcon 9 flew in March, with the second one following close behind in June. It's possible we'll see more used rockets fly before the year is out: earlier this year, Musk said the company could fly as many as six used boosters in 2017. Eventually, SpaceX hopes to refly its Falcon 9s much more frequently, by making a landed booster ready to fly again in just 24 hours.

Going up on this flight is a hybrid satellite that will be used by two companies, SES and EchoStar. Called EchoStar 105/SES-11, the satellite will sit in a high orbit 22,000 miles above Earth, providing high-definition broadcasts to the US and other parts of North America. While this is the first time EchoStar is flying a payload on a used Falcon 9, this is familiar territory for SES. The company's SES-10 satellite went up on the first "re-flight" in March. And SES has made it very clear that it is eager to fly its satellites on previously flown boosters.

Update: Liftoff was successful and the first stage landed successfully on a drone ship in the Atlantic Ocean.

Update 2: EchoStar 105/SES-11 successfully deployed.
