NASA intends to issue a sole source modification to SpaceX to acquire up to
three additional crew flights to the International Space Station as part of
its Commercial Crew Transportation Capabilities (CCtCap) contract. The
additional crew flights allow NASA to maintain an uninterrupted U.S.
capability for human access to the space station.
In October, NASA issued a request for information from American industry
capable of providing safe, reliable, and cost-effective human space
transportation services to and from the International Space Station to
ensure a continuous human presence aboard the microgravity laboratory.
After a thorough review of the near-term certified capabilities and
responses from American industry, NASA’s assessment is that the SpaceX crew
transportation system is the only one certified to meet NASA’s safety
requirements to transport crew to the space station, and to maintain the
agency’s obligation to its international partners in the needed timeframe.
“It’s critical we begin to secure additional flights to the space station
now so we are ready as these missions are needed to maintain a U.S. presence
on station,” said Kathy Lueders, associate administrator, NASA’s Space
Operations Mission Directorate. “Our U.S. human launch capability is
essential to our continued safe operations in orbit and to building our
low-Earth orbit economy.”
NASA anticipates a potential need to use any additional flights as early as
2023 to maintain mission readiness. Securing additional flights now also
allows NASA to continue working with Boeing on the development of the
company’s CST-100 Starliner spacecraft, which also will fly NASA and
international partner astronauts to and from the space station after
completing its certification effort.
“NASA commends Boeing for its ongoing investigation of the oxidizer
isolation valve issue that was discovered ahead of the planned uncrewed
Orbital Flight Test-2 (OFT-2) mission to the International Space Station in
August, prioritizing safety over schedule while working to solve this
challenge,” said Phil McAlister, director, commercial spaceflight at NASA.
“NASA and Boeing will provide additional updates on the status of
Starliner’s next mission as we work through the investigation and
verification efforts to determine root cause and effective vehicle
remediation.”
NASA continues to have a need for two unique crew capabilities to ensure
dissimilar redundancy, maintain safe space station operations, and allow
each company to work through any unforeseen issues that could arise as
private industry builds operational experience with these new systems.
NASA’s plan is still to alternate missions between SpaceX and Boeing, once
both are operational.
The current sole source modification does not preclude NASA from seeking
additional contract modifications in the future for additional
transportation services as needed.
NASA also is working to extend the life of the space station beyond 2024 to
allow for a seamless transition to commercially operated, low-Earth orbit
destinations and allow NASA to continue its vital scientific research to
prepare for human exploration beyond low-Earth orbit to benefit life on
Earth. NASA continues to anticipate a need for crew transportation into the
foreseeable future as the agency enables a low-Earth orbit economy.
In 2014, NASA awarded the CCtCap contracts to Boeing and SpaceX through a
public-private partnership as part of the agency’s Commercial Crew Program.
Under CCtCap, NASA certifies that a provider’s space transportation system
meets the agency’s requirements prior to flying missions with astronauts.
After years of development, commercial crew systems have achieved or are
nearing operational readiness for regular crewed missions, including
providing a lifeboat capability, to the space station.
For more than 20 years, NASA has continuously had astronauts living and
working aboard the International Space Station, advancing scientific
knowledge and demonstrating new technologies, making research breakthroughs
not possible on Earth. As a global endeavor, 249 people from 19 countries
have visited the unique microgravity laboratory that has hosted more than
3,000 research and educational investigations from researchers in 109
countries and areas.
The station is a critical testbed for NASA to understand and overcome the
challenges of long-duration spaceflight and to expand commercial
opportunities in low-Earth orbit. As commercial companies focus on providing
human space transportation services and developing a robust low-Earth orbit
economy, NASA is preparing for human exploration of the Moon and Mars.
