SUMMARY: Now well on its way to the Red Planet, the European Space Agency's Mars Express spacecraft took a farewell image of the Earth and Moon. The photo was snapped on July 3 when the spacecraft was 8 million kilometres away from the Earth. The picture was taken as part of a series of tests the ESA is doing to make sure the Mars Express' cameras and instruments are working properly. Once it reaches Mars in late December, the spacecraft will be able to resolve objects on the surface of Mars as small as 2 metres.

If you look really close, you can see me waving from that blue ball.

"It looks like a beautiful burn," said Jim Erickson, Mars Exploration
Rover mission manager. "The thrusters fired correctly. We're on course
for putting both spacecraft on Mars."


"As of 6 a.m. Pacific Daylight Time July 19, Opportunity will have
traveled 31.5 million kilometers (19.6 million miles) since its July 7
launch. Spirit, launched on June 10, will have traveled 106.9 million
kilometers (66.4 million miles). Spirit completed its first
trajectory correction maneuver three weeks ago."

What are the goals of these two missions?

Together the two MER rovers,
Spirit and Opportunity, seek to determine the history of climate and water
at two sites on Mars where conditions may once have been favorable to life.
The rovers are identical. Each rover carries five scientific instruments
including a panoramic camera and microscope, plus a rock abrasion tool that
will grind away the outer surfaces of rocks to expose their interiors for
examination. The rovers each weigh approximately 400 pounds. They will
navigate themselves around obstacles as they drive across the Martian surface,
traveling up to about 130 feet each Martian day. Each rover's prime mission
is planned to last three months on Mars.
