This is the first launch attempt of a Block 5 Falcon 9. Assuming SpaceX gets a few of these safely under their belt, they can use them to launch NASA crews to the ISS, finally putting the US back into the manned space launch business again. This launch is sending up the first Bangladeshi geosynchronous comsat. Launch is current scheduled for 3:47 PM, Mountain time, followed by a planned recovery of the first stage on a barge.
