Scientists at the US space agency Nasa have released the first 3D image of Mars sent from the Spirit probe that landed on the planet on Sunday.
The image is a 360-degree panoramic view of Spirit's Martian landing site but it can only be appreciated best when viewed through a 3D viewer.
The first colour images will probably come back on Tuesday, say scientists.
The resolution of Spirit's images will be far superior to those taken during 1997's Mars Pathfinder mission.
Scientists have spotted a surface depression nicknamed "Sleepy Hollow" in the latest pictures.
This feature, measuring about 10 metres (30 feet) in diameter and located approximately 10-20 metres (30-60 feet) away from Spirit is either an impact crater or a product of wind-erosion.
Nasa scientists are also trying to establish a direct communications link with Spirit.
At present, they are only able to communicate with the robotic vehicle indirectly, via a satellite in orbit around the planet.
Scientists are preparing to get the probe to stand upright. They say everything seems to be working well.
US MARS ROVERS
Spirit targeted at Gusev Crater, possible ancient lake feature
Opportunity to land at Meridiani Planum, which contains minerals often associated with water
Spirit and Opportunity weigh about 17 times as much as the 1997 Sojourner rover
The robot is to seek signs that Mars was once capable of supporting life.
Scientists are trying to establish which direction to head off in when the six-wheeled robot makes its first tentative moves on the planet.
They are waiting for higher quality images to guide them so as to avoid any dangerous craters or boulders.
The rover is currently folded up on its landing pad and will not start driving around on the surface for at least a week or roughly nine sols. A sol is a Martian day.
Engineers are deploying the vehicle's solar panels as the Sun rises to power it for exploration.
The six-minute descent to the surface was the most daunting leg of the 500-million-kilometre journey.
In the past, two out of three attempts to land spacecraft on the Red Planet have failed.
The European Space Agency is still searching for the missing British-built Beagle 2.
The probe was supposed to land on Mars on Christmas Day but has not yet sent back a signal to confirm it has arrived safely.
Spirit is one of a pair of rovers that will seek evidence for water on Mars.
Its twin, Opportunity, will touch down on the other side of Mars in late January.
Mission scientist Dr Steve Squyres, from Cornell University in New York, said Spirit and Opportunity, would act as robotic field geologists.
"They look around with a stereo, colour camera and with an infrared instrument that can classify rock types from a distance," he said.
"They go to the rocks that seem most interesting. When they get to one, they reach out with a robotic arm that has a handful of tools, a microscope, two instruments for identifying what the rock is made of, and a grinder for getting to a fresh, unweathered surface inside the rock."
Spirit will explore the Gusev Crater, just south of the Martian equator, which may once have held a lake.
But before it starts trundling over the surface of Mars it must scan its surroundings and carry out engineering checks.
