HOUSTON — NASA chief
Michael Griffin lamented the mandated 2010 retirement of the agency's space
shuttle fleet and the all-too-likely possibility that U.S. astronauts will be
absent from the International Space Station for extended periods in the future
in a leaked e-mail intended for top advisors.
The Aug.
18 e-mail, first reported Sunday by the Orlando Sentinel newspaper,
includes candid remarks by the U.S. space agency Administrator, where he
likened the push to retire the shuttle by 2010 as a "jihad" to
shut down the program rather than one based on engineering and program
management.
Griffin also greatly detailed many of the themes present in the leaked e-mail during a Sept. 2
interview with SPACE.com sister publication Space News. [Click

NASA is
planning to replace the space shuttle with its Orion Crew
Exploration Vehicle and its Ares I rocket booster, but the new space
transportation system is expected to begin manned flights no earlier than 2014,
leading to gap in U.S. spaceflight capability. Part of the reason
for the hiatus, NASA officials have said, has been budget limitations that forced
NASA's Constellation program overseeing Orion and Ares booster development to
push back their internal manned launch test target by a full year last month.
"In a
rational world, we would have been allowed to pick a Shuttle retirement date to
be consistent with Ares/Orion availability, we would have been asked to deploy
Ares/Orion as early as possible (rather than "not later than 2014") and we
would have been provided the necessary budget to make it so," Griffin wrote in
the e-mail.
Griffin
also expressed frustration over the likelihood that Congress would not extend
the agency's ability to buy seats and cargo space aboard the Russian-built
Soyuz and Progress spacecraft beyond 2011 due to Russia's
recent military conflict with its neighbor state Georgia. Without the
extension, and with the gap between shuttle retirement and start of Orion
operations, there will likely be long periods in which U.S. astronauts and
those of NASA partners are absent from future space crews.
In a
statement issued after the Orlando Sentinel posted Griffin's e-mail, the
space agency administrator stressed that the memo alone lacked the appropriate
context.
"The leaked
internal email fails to provide the contextual framework for my remarks, and my
support for the Administration's policies," Griffin said the NASA statement.
"Administration policy is to retire
the shuttle in 2010 and purchase crew transport from Russia until Ares and
Orion are available."
NASA's
approval to fly U.S. astronauts and cargo on Russian spacecraft comes under an
exemption from the Iran-North Korea-Syria Non-proliferation Act (INKSNA). In
the leaked e-mail, Griffin states that ongoing tension between Russian and
Georgia would likely prevent Congress from approving any exemption extension
that would allow NASA to pay for additional Russian spacecraft.
"We might
get relief somewhere well down the road, if and when tensions ease, but my
guess is that there is going to be a lengthy period with no U.S. crew on ISS
after 2011," Griffin wrote.
He also
added that Russia's Federal Space Agency could operate the $100 billion space
station without the U.S., and stressed that NASA would take no measures to
force the country to allowing U.S. use of Soyuz and Progress, such as denying
access to U.S.-built station power systems or other hardware.
"Practically
speaking, the Russians can sustain ISS without US crew as long as we don't
actively sabotage them, which I do not believe we would ever do, short of war,"
Griffin wrote. "We need them," he later added. "They don't 'need' us. So we're
a 'nice to have.'"
In his
Sunday statement, Griffin stressed that the space agency does in fact have the
support of the current Administration for the INKSNA exemption.
"The Administration
continues to support our request for an INKSNA exemption," Griffin said in the
statement. "Administration policy continues to be that we will take no action
to preclude continued operation of the International Space Station past 2016."
Last week,
Griffin called on shuttle program managers to begin looking into what would be
required to extend the
space shuttle fleet's service beyond the current 2010 retirement date. NASA
officials said the study was intended for preparation uses only in order to ready
the agency to answer any space shuttle program-related inquires from the new incoming
president and administration.
