The first launch of a Falcon Heavy is currently scheduled for late
this summer. According to Elon Musk, the test flight will be with two
reflown Falcon 9 Cores (plus one new one) and they may attempt to
recover the upper stage to prove full reusability, although he
considers the odds of that succeeding on the first attempt to be low.
