NASA's Mars Rover Sends Its First Photos

The first images of the Martian surface taken by the Spirit Mars Rover are being received on Earth via the orbiting Mars Odyssey spacecraft.

“What a night!” said principal investigator Steve Squyres. “Spirit has shown us her new home in Gusev crater. It’s a glorious place. It is a wonderful place from a scientific perspective in several different ways. First of all, not only have we landed at Gusev crater, but we now have the first evidence suggesting where we landed. We have hit what the science team believes to be the science sweet spot of Gusev crater.”

NASA’s Mars Rover Sends Its First Photos

PASADENA, Calif. - NASA (news - web sites)'s Spirit rover has sent its first images from Mars, showing a landscape scattered with small rocks that brought cheers from scientists.

The National Aeronautics and Space Administration began receiving the first of an estimated 60 to 80 images from Spirit’s cameras late Saturday, just three hours after the robot made an apparently flawless landing on Mars.

Re: NASA’s Mars Rover Sends Its First Photos

One thing which I always wanted to know, but figured its probably a bit too dumb from a scientific point of view is regarding these parachutes deployed by space crafts when they are landing on distant planets. How do they help the descent? I mean, I’d think that a parachute will be useful if there is air in the climate which will slow down the descent to a more managable speed. So, should we assume that there is “air” around the surface of Mars??? :konfused:

^it need not be air that shud be around aplanet......any gass would suffice provided the parachute can handle it.

so it needn't be the mixture of O2, N2 and CO2, just a gass would be good enough (don't know which gass it is on Mars, but there is)

Mars has gravity, as well as an atmosphere (a collection of gases). Mars is not merely a ball of rock floating in space, so this capsule is not travelling in ordinary space until the time it actually hits mars, but is encapsulated in the atmosphere, which is why these parachutes are needed, very simple explanation.

Mars does have a thin atmosphere of mostly CO2, enough to slow a descent using parachutes.

I don't get why MARS missions are so messed up..I mean porbes have reached neptune without as many problems!

It’s the landing of a sophisticated rover that's the key. The missions to Mars (Viking, US) and Venus (Venera, Russia) in the past were still a challenge but a little easier as the probe was a lot more 'solid state' and less easily damaged and not required to do much other than sit and transmit and then melt away in the case of Venus.

The fly bys to the outer planets still require detailed planning and insane mathematics but don't involve descents and sampling of physical material and thus are less complicated in a sense.

2004 starts with a BANG - success at last!

Mars probe ‘in great shape’

The robotic probe Spirit has landed in a prime spot for exploring Mars.
The first panoramic image taken by the six-wheeled robot shows what appears to be an impact crater carved by a space rock crashing into the planet.

Scientists plan to send the vehicle to investigate the dust-filled bowl once it is ready to move away from its landing site.

Impact craters are a good place to look for reservoirs of ice that are thought to be buried under the Martian surface.

Mission scientists have dubbed the crater “sleepy hollow”. “It’s a hole in the ground, it’s a window in the interior of Mars,” said chief scientist Steve Squyres. “It’s a very exciting feature for us, probably the place we are going to go first.”

**Dream mission **

Images and data sent back by Spirit are continuing to delight scientists.

“Once again in this instance, reality has far surpassed fantasy,” said technical specialist Art Thompson.

“…We can hardly wait until we get off the lander so we can start driving and doing fun stuff on the surface.”

Spirit is about to wake up to spend its third Martian day on the surface.

Mission controllers, who are working on Martian time, plan to carry out more health checks on the rover as well as further preparations to prepare it for action.

On Monday, they established a direct communications link between Earth and the probe.

This means that Spirit can be commanded from the ground rather than relying on data sent via an orbiting spacecraft.

Scientists have confirmed that all of the scientific instruments tested so far are in good working order.

They include a device for analysing chemicals in rocks that appeared to be malfunctioning during the long cruise from Earth.

**Panoramic images **

Spirit is continuing to send back spectacular images of the Martian surface, including the first panoramic shot of where it bounced to rest.

The rover has taken what should be the best shot yet of its terrain, which will be sent back to Earth on Tuesday.

It 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.

There are concerns that airbags lodged against the front of the craft might block its path.

Commands will be sent to the probe on Tuesday in an attempt to retract the airbags to clear the obstruction.

**Twin explorers **

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.

Spirit will explore the Gusev Crater, just south of the Martian equator, which may once have held a lake.

Opportunity is landing in an area thought to be rich in chemicals associated with water.

more then enough for the parachute to work :smiley:
