SpaceX SpaceX Falcon 9 Block 5 Launch
SpaceX is making history again today as it prepares for its first Falcon 9 Block 5 launch. This newest version of the Falcon 9 rocket will launch the Bangabandhu 1 communications satellite from NASA’s Kennedy Space Center in Florida. The Block 5 has many upgrades that will allow greater reusability and up to 10 launches (the Block 4 was limited to two launches.) With some refurbishments, the Block 5 might be able to have up to 100 launches, the company has said. But what else makes the Block 5 exciting is that it meets NASA’s requirements for carrying crew, and this might happen sometime this year. You can watch the launch on the live stream video below.
The launch window for today is from 4:12 p.m. Eastern to 6:22 p.m. Eastern. Currently, SpaceX is scheduling the launch today for 5:47 p.m. Eastern.
Approximately 33 minutes after the launch, the satellite will be deployed into a geostationary orbit, SpaceX has said. If the launch window today is missed, a backup launch window is scheduled for Friday, May 11, at 4:14 p.m. Eastern – 6:21 p.m. Eastern.
After the launch, SpaceX will attempt to land the rocket’s first stage on a drone ship (called “Of Course I Still Love You”) off the Florida coast. Fairing 2 is also on the launch vehicle, but it won’t be recovered because right now, the only recovery boat is in California, reported NASA Spaceflight.

In total, about 30 to 50 Block 5s are planned, SpaceX has said, but the exact number depends on how many customers they have. The Block 5 exceeds all NASA requirements for crew and meets all Air Force requirements, Elon Musk said.

Ultimately, they may be able to get even more power out of the engines than what we will see today.
