SpaceX Launches Used Rocket for 13th Time

[vc_row][vc_column][vc_column_text]SpaceX successfully launched today a satellite using a used rocket for the 13th time.

A Falcon 9, which previously lofted the U.S. Air Force’s X-37B space plane, successfully deployed the SES-12 satellite to orbit. The mission was for Luxembourg-based SES, which launched the satellite to offer data and video services to the Asia-Pacific region.

SES has an important place in SpaceX history, as it was the first SpaceX customer that agreed to employee a used Falcon 9. The SES-10 satellite was launched on March 30, 2017.

The mission lifted off from Florida’s Cape Canaveral Air Force Station at 12:45 a.m. ET.

SpaceX did not attempt to recover the first stage booster for this flight, as it’s phasing out this generation of rocket in favor of the more resilient “Block 5″ version of the Falcon 9.

Block 4 only gets reused once.

I am crossing my fingers that a Block 4 gets a third reuse with the In Flight Abort test for Commercial Crew. The TESS booster (B1045) landed on OSCILY in spectacular shape. It's next launch for CRS-15 will also be an easy RTLS recovery with minimal wear and tear as well. So I'm hoping that booster gets a third reuse with the In Flight Abort test.

The ongoing rumor is that they will reuse the KoreaSat 5A (B1043) booster for the In Flight Abort though.

Question about the time gap between the end of second stage burn two and when they release the satellite. After the second burn is over, why hold onto the satellite for so long if the second stage is done at that point? Why not release it shortly after the burn is over once everything checks out? If there aren’t any additional burns planned what’s the point of holding onto it for so long after?

Yay! Went great.
I love the way the altitude climbs and velocity falls even after SECO2- remarkable to think about that elegant silent HIGH-altitude trajectory....

Successful launch. Some drama over a lens flare after liftoff. Nothing fell off. Everything else went successful except some mylar shielding came loose on the second stage and flapped around. It didn't prevent the successful deployment of the satellite in the desired position.

They are waiting for a specific pre-arranged point in space to release. It may take a while to reach that point. Maybe there are some satellite checks that SES needs to do.

It's a good question and I am just speculating.
