Mars orbiter granted reprieve from government closure

Engineers returned to work on NASA's next Mars mission at the Kennedy
Space Center on Thursday after receiving an emergency exception under
federal law to continue launch preparations for a $671 million orbiter
to probe the red planet's atmosphere.

The decision keeps the Mars Atmosphere and Volatile Evolution, or MAVEN,
mission on schedule for liftoff Nov. 18 at the opening of a 20-day primary
launch window.

"I learned this morning that NASA has analyzed the MAVEN mission relative
to the Anti-Deficiency Act and determined that it meets the requirements
allowing an emergency exception," said Bruce Jakosky, MAVEN's principal
investigator from the University of Colorado at Boulder's Laboratory for
Atmospheric and Space Physics.

NASA sent 97 percent of its civil servant workforce home Tuesday after
Congress failed to pass a federal budget, only granting exceptions for
activities deemed essential for the protection of life or property.

While administrators, support staffs and scientists were furloughed, operations
of the International Space Station in support of its six-person crew continued
this week, along with data-gathering activities on the Hubble Space Telescope
and NASA's rovers and orbiters already at Mars.

But the government shutdown halted work on missions still in development
on the ground, such as MAVEN.

Officials feared an extended government shutdown could threaten the mission's
ability to launch by mid-December, the last chance to send a spacecraft
to Mars until the planets are in the right positions again in early 2016.

With the MAVEN work stoppage lifted Thursday, engineers lost about three
days of work on the spacecraft. But officials with Lockheed Martin Corp.,
MAVEN's prime contractor, said last week the mission was nine days ahead
of schedule going into the shutdown.

"Good news for us, although we're very sensitive to the fact that there
are still 800,000 government employees who are furloughed," Jakosky told
Spaceflight Now.

Teams returned to work on MAVEN inside the Payload Hazardous Servicing
Facility at KSC on Thursday afternoon, Jakosky said.

"We have already restarted spacecraft processing at Kennedy Space Center,
working toward being ready to launch on Nov. 18," Jakosky wrote in an
update emailed to reporters. "We will continue to work over the next couple
of days to identify any changes in our schedule or plans that are necessary
to stay on track."

Jakosky said it will take a day to ramp up activities and fully resume
preparations on MAVEN.

NASA's exception for MAVEN was granted under the guise of the orbiter's
importance as a communications relay platform for the $2.4 billion Curiosity
rover and the venerable Opportunity robot exploring the Martian surface.

The Mars Odyssey mission and Mars Reconnaissance Orbiter currently provide
communications support for the rovers, but both orbiters are flying well
beyond their design lives.

"Launching MAVEN in 2013 protects the existing assets that are at Mars
today," Jakosky said. "A delay in the launch date by more than a week
past the end of the nominal launch period, or a delay of launch to 2016,
would require additional fuel to get into orbit. This would have precluded
having sufficient fuel for MAVEN to carry out its science mission and
to operate as a relay for any significant time."

Scientists are also eager to launch MAVEN in time for the spacecraft's
suite of solar wind monitors, particle sensors and atmospheric instruments
to observe how the Martian atmosphere responds to stimuli from solar activity.

MAVEN is designed to study how gases escape from the upper atmosphere
of Mars, which could tell scientists how the red planet evolved from a
world hospitable for life to the barren planet of today.

"Although the exception for MAVEN is not being done for science reasons,
the science of MAVEN clearly will benefit from this action," Jakosky said.
"Launching in 2013 allows us to observe at a good time in the eleven-year
solar cycle."
