# Mars rover Spirit to be officially retired
## Spirit, the scrappy robot geologist that captivated the world with its
antics on Mars before getting stuck in a sand trap, is about to meet its end
after six productive years.

Spirit has been incommunicado for more than a year despite daily calls by
Nasa. The cause of Spirit's silence may never be known, but it's likely the
bitter Martian winter damaged its electronics, preventing the six-wheel rover
from waking up.
The space agency for months tried every trick to communicate with Spirit to no
avail. Project manager John Callas of Nasa's Jet Propulsion Laboratory said
the last commands will be sent up later today. Though orbiting spacecraft will
continue to listen through the end of May, chances are slim that Spirit will
respond.
"Spirit went into a deep sleep," said Mr Callas, who said the plucky rover
will be remembered for demystifying Mars to the masses.
When the rover team gets together this summer, David Lavery of Nasa
headquarters said the mood would likely be that of an Irish wake rather than
funeral.
"We drove it until its wheels came off," he said. "We never expected that that
would be the way that we'd finish up with this project."

The solar-powered Spirit and its twin Opportunity parachuted to opposite ends
of the Martian southern hemisphere in January 2004 for what was supposed to be
a three-month mission.
The golf cart-size rovers were an instant hit with the public who followed the
rovers' every move as they rolled across the Martian plains and stopped to
drill into rocks.
Their greatest achievement was uncovering geologic evidence that Mars, now dry
and dusty, was far more tropical billions of years ago. The red planet was
toastier and wetter, conditions that suggest the ancient environment could
have been favorable for microbial life.
As far as sibling rivalry went, Opportunity was the overachiever while Spirit
was every bit the drama queen underdog.
Soon after landing, Spirit went into critical condition and sent nonsense data
back to Earth. Engineers had to nurse it back from the brink of death.
Unlike Opportunity, which landed in an ancient lakebed awash with water-
forming minerals, Spirit plopped into a Connecticut-sized crater named Gusev
that contained limited hints of past water.
Spirit had no choice but to trek toward the hills to make discoveries. It
managed to shine despite having a rocky start on Mars.
In 2005, Spirit scaled a mountain the height of the Statute of Liberty. It
also was the first to record Martian dust devils as they formed, which Nasa
later made into movie clips.
As the years passed, Spirit began showing signs of aging.
In 2006, one of its front wheels stopped spinning, forcing the rover to drive
backward and drag its lame wheel. More recently, it suffered bouts of amnesia
by failing to record data to its flash memory.
Spirit survived three Martian winters, but the hardy rover was no match for
the latest cold.
The troubles began in April 2009 when Spirit broke through crusty ground while
driving backward and became bogged in a sand pit. During attempts to get it
unstuck, one of the back wheels stopped working - essentially turning Spirit
into a four-wheel drive.
Unable to provide roadside assistance, Nasa declared an end to Spirit's mobile
career in January 2010 - six years after landing - and it became a stationary
spacecraft.
A formal farewell is planned at Nasa headquarters after this weekend's
Memorial Day holiday and will be televised on Nasa TV.
