The Falcon 9 had its first major failure in late June 2015, when the seventh ISS resupply mission, CRS-7 exploded two minutes into the flight. The problem

2880-457: The company. Based on these factors and the further business operations they enabled, the Falcon 1 was soon retired following its second successful, and fifth total, launch in July 2009. This allowed SpaceX to focus company resources on the development of a larger orbital rocket, the Falcon 9. Gwynne Shotwell was also promoted to company president at the time, for her role in successfully negotiating

2952-517: The competition from SpaceX. Beginning in 2014, SpaceX capabilities and pricing also began to affect the market for launch of U.S. military payloads, which for nearly a decade had been dominated by the large U.S. launch provider United Launch Alliance (ULA). The monopoly had allowed launch costs by the U.S. provider to rise to over $ 400 million over the years. In September 2014, NASA's Director of Commercial Spaceflight, Kevin Crigler, awarded SpaceX

The unit is named after Blaise Pascal , noted for his contributions to hydrodynamics and hydrostatics, and experiments with

4104-544: The rocket explosion sent the company into a four-month launch hiatus while it worked out what went wrong. SpaceX returned to flight in January 2017. In March 2017, SpaceX launched a returned Falcon 9 for the SES-10 satellite. This was the first time a re-launch of a payload-carrying orbital rocket went back to space. The first stage was recovered again, also making it the first landing of a reused orbital class rocket. In July 2017,

4176-474: The same time. Musk was reportedly "waking from nightmares, screaming and in physical pain" because of the stress. The financial situation started to turn around with the first successful launch achieved on the fourth attempt on 28 September 2008. Musk split his remaining $ 30 million between SpaceX and Tesla, and NASA awarded the first Commercial Resupply Services (CRS) contract awarding $ 1.6 billion to SpaceX in December, thus financially saving

4248-415: The test flight as a success. Musk said at the time that it would take "six to eight weeks" to get the infrastructure prepared for another launch. In October 2023, a senior SpaceX executive stated the company had been ready to launch the next test flight since September. He accused government regulators of disrupting the project's progress, adding the delay could lead to China beating U.S. astronauts back to
