. As a result of downtime to conduct repairs, and bad sea conditions at the end of the year, Sea Launch did not conduct another launch until 2008. On 21 March, SpaceX launched the second Falcon 1. Due to the failure of the maiden flight, the launch was conducted as a demonstration flight without a functional payload. The launch failed to reach orbit due to a chain of events, starting with an error in setting the fuel mix ratio, which resulted in first stage underperformance, and the rocket being too low at the time of first stage separation. Additional atmospheric drag at this altitude caused recontact between the stages, setting up a fuel slosh in the second stage. This resulted in the premature cutoff of the second stage, and the rocket failed to reach orbit. This was the last launch of the Falcon 1 with the ablatively cooled Merlin-1A engine, which was replaced with the regeneratively cooled Merlin-1C for subsequent flights, starting in August 2008. As several test objectives were completed, SpaceX claimed that the launch was a success overall, and declared the Falcon 1 operational. The
