WASHINGTON — To deal with the nearly $900 million budget hit NASA will absorb if automatic spending cuts known as sequestration are allowed to take effect March 1, the U.S. space agency would slow development work on commercially operated astronaut taxis, delay or cancel space technology programs and postpone the launch of some small science missions.
NASA Administrator Charles Bolden outlined the space agency’s sequestration plans in a Feb. 5 letter to Senate Appropriations Committee Chairwoman Barbara Mikulski, D-Md., who released it following a Feb. 14 hearing.
NASA’s overall budget would drop to $16.9 billion, down from the $17.8 billion Congress approved last year.
Spending on the commercial crew program NASA is using to subsidize development by Boeing, Space Exploration Technologies (SpaceX) and Sierra Nevada of competing human spaceflight systems would be reduced to $388 million — $18 million less than it is currently spending and $441.6 million less than the agency had been planning to spend in 2013.

NASA, like all federal agencies, has had its funding frozen at 2012 levels under a stopgap spending measure known as a continuing resolution that expires March 28. NASA’s sequestration plan assumes that the continuing resolution will be extended through Sept. 30, the end of the U.S. government’s 2013 fiscal year.
Bolden said NASA’s commercial crew partners would feel a funding pinch as soon as July.
Among the commercial crew activities planned for later this year that NASA would not be able to fund after sequestration are:
"Overall availability of commercial crew transportation services would be significantly delayed, thereby extending our reliance on foreign providers for crew transportation to the International Space Station," Bolden wrote.
Meanwhile, a sequester would also put the screws to NASA’s Space Technology Program, a White House priority under President Barack Obama. Instead of getting the $699 million sought for the program, NASA would cut its budget back to $550 million, or about $24 million less than it has now.
To absorb the cut, NASA would consider canceling programs now in the development stage, including a highly publicized demonstration of a deep-space atomic clock, which was set to fly as a hosted payload on an Iridium Next satellite scheduled for launch in 2015. Four other space technology programs could also wind up on the chopping block, Bolden warned, and nine others might be delayed.
Small astrophysics and Earth science missions would also suffer under NASA’s plan to reduce the Science Mission Directorate’s budget to $4.86 billion. While that is only $51.1 million less than Science would have received under the agency's 2013 budget request, it is $200 million less than the mission directorate has today.
To absorb the cut, NASA intends to award 5 percent fewer research grants this year and reduce funding for new Explorer- and Earth Venture-class missions by 10 to 15 percent. Bolden said this would result “in lower funding levels for new activities and causing minor launch delays.”
The next missions scheduled for launch in NASA’s Explorer line of small astrophysics missions are the Interface Region Imaging Spectrograph, an ultraviolet observatory slated for an April launch, and Astro-H, an X-ray observatory scheduled to launch in February 2014.
The next Earth Venture launch on NASA’s calendar is the Orbiting Carbon Observatory-2, which is supposed to lift off in July 2014.
