[Update: I noticed that the YouTube Live Feed page now shows the launch to be scheduled for 20:42 UTC -- a 30 minute delay. This is confirmed by SpaceX's Twitter feed. --martyb]
[Update 2: Another hour and 5 minutes of delay. T-0 scheduled for 5:47 PM EDT (21:47 UTC). --takyon]
[Update 3: The rocket aborted the launch sequence at T-58s. Launch window tomorrow at 4:14 PM EDT (20:14 UTC) to 6:21 PM EDT (22:21 UTC). --takyon]

A Falcon 9 rocket has gone vertical on Thursday morning at Launch Complex 39A in Florida, and SpaceX is on track for the liftoff of a brand new version of its workhorse booster. The launch of the Bangabandhu Satellite-1 to geostationary transfer orbit is set for 4:12pm ET (20:12 UTC) Thursday, with a launch window that stretches for a little more than two hours.
The highlight of this flight is the debut of the Block 5 version of the Falcon 9 rocket (which Ars previewed thoroughly last week). SpaceX founder Elon Musk has said this will be the final "substantial" upgrade to the Falcon 9 rocket, optimizing the booster for reuse. The company hopes to be able to fly each Block 5 first stage 10 times before significant refurbishment is required.
[...] Ten flights of an individual booster would be hugely significant, as SpaceX has thus far only ever reused each of its Falcon 9 rockets a single time. Additionally, the company hopes to reduce the turnaround time between launches of a Falcon 9 booster, now several months, to a matter of weeks.
The launch will be live-streamed on YouTube:
SpaceX is targeting launch of Bangabandhu Satellite-1 on Thursday, May 10 from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center, Florida. The launch window opens at 4:12 p.m. EDT, or 20:12 UTC, and closes at 6:22 p.m. EDT, or 22:22 UTC. Bangabandhu Satellite-1 will be deployed into a geostationary transfer orbit (GTO) approximately 33 minutes after launch.
A backup launch window opens on Friday, May 11 at 4:14 p.m. EDT, or 20:14 UTC, and closes at 6:21 p.m. EDT, or 22:21 UTC.
The Bangabandhu Satellite-1 mission will be the first to utilize Falcon 9 Block 5, the final substantial upgrade to SpaceX's Falcon 9 launch vehicle. Falcon 9 Block 5 is designed to be capable of 10 or more flights with very limited refurbishment as SpaceX continues to strive for rapid reusability and extremely high reliability.
Following stage separation, SpaceX will attempt to land Falcon 9's first stage on the "Of Course I Still Love You" droneship, which will be stationed in the Atlantic Ocean.

Redundancy and competition just needs two - SpaceX and Blue Origin will give you that just fine, two launch providers for a fraction of the cost of SLS.
Of course it does depend if you are really buying rockets or pork...

Two is an oligopoly. They collude to raise prices. It's effectively a cartel.
You're doing OK when nobody has more than 15% market share (any way you measure it) and you're doing well when nobody has more than 10% market share.
