Three NASA and Defense Department satellites–and the ashes of 200 people including Mercury astronaut Gordon Cooper and Star Trek’s “Scotty” — were lost this weekend with the failed launch of Space X’s Falcon 1. In a touching press release, Paypal founder and Space X head Elon Musk called the loss of the rocket a “disappointment” but didn’t mention the payload it was carrying. That was followed by 3 paragraphs of cheerleading, outlining all the positives that the company learned from the launch failure and reassuring people that Space X had sufficient funds to keep pressing forward. “Now, on to flight 4” says Musk. Who does his PR?
