You need a Falcon Heavy for today's launch, but the problem here is that there is no such thing as a Falcon Heavy. It doesn't exist yet, or ever. Not to mentio

You need a Falcon Heavy for today's launch, but the problem here is that there is no such thing as a Falcon Heavy. It doesn't exist yet, or ever. Not to mention there's risk in NASA putting its Orion dreams on something thats currently unproven. If the publish saw Orion blow up today then that could prove disastrous for the SLS program.
