mars rover

• Question:-Mars Rover is still running and we drive to work using a century old combustion engine, WHY?
  Given, the Mars Rover is still running on solar panels, giving off 0 emissions, a technological marvel and is 36 million miles away. The primary form of transportation on earth is the century old combustion engine, spewing off emissions. Regardless as to whether the earth or humanity will succumb to the effects of our dirty habits, why do we allow this to happen?
  Did you know that we get enough energy from the sun in about 2 hours to provide all of the worlds energy needs?
  The point is, we have the technology, Mars Rover, Nuclear powered subs, Cern, but we cruise around in vehicles with combustion engines.
  
  Answer:-I brought up the same question at work, the rover has been going for a long time and I'm not sure but I don't think there are any gas stations on mars!
  People need to stop using gas and force a change, as long as the oil companies make billions per quarter they will continue to pay everyone off so they can continue to use gas.
  
  Check out the movie, who killed the electric car. it's an eye opening experience.
• Question:-Why is Mars rover Opprotunity making fast progress toward a destination of its own?
  Why is it that mars rover spirit has reached a safe sit for the martian winter, while its twin, opportunity, is making fast progress toward a destination of is own?
  
  Answer:-Spirit has been mired in a sand trap for six months and may be stuck for good:

  Opportunity is continuing it's two-year drive to Endeavour crater.
• Question:-Can you download the Mars Rover pictures made public in bulk?
  Is there any place that you can download all the mars land rover pictures that were made public in bulk? Perhaps a torrent or otherwise from the Nasa archives?
  Thanks!
  
  Answer:-You could wait for a random response from some millions of users who may or may not know or even see your question or you could ask the webmaster for the NASA site. Which one do you think is going to get you the best and quickest answer?
• Question:-How do we recieve a signals from a rover on Mars?
  I assume the Mars rover has a small antenna with a low power transmitter. If this is the case how does that signal get reicieved all the way on earth? Is there some sort of satellite relay system? It seems to me that it would be difficult to discern the signal from all the random noise. Maybe some sort of special encoding is used on the signal. I don't know....does anyone know the answer?
  
  Answer:-As far as i know both Rovers do only have a UHF transmitter making them incapable sending something directly to earth.
  
  Instead they relay(ed) data through Mars Odyssey, Mars Global Surveyor, Mars Express and possibly the new Reconaissance Orbiter.
  
  if Transmitter Power is limited it needs large antennas to even receive signals from the satellites around mars, due to the fact that it could be on the other side of the sun, from time to time.
  Distance and lack of power causing effects of course. So therefore they switch to lower transmission speeds, and use algorithms to be able to reconstruct lost bits in the stream.
  
  This was all considered on planning, so it was decided not to have the rovers transmit directly.
  Instead having redundant orbiters to relay which have no problems with sand on their solar-panels.

• Question:-When will be the mars rover sent to the mars?
  Do we know exact date of rover to mars?
  Edward, if there are rovers on the mars' surface, then why are there no videos of good quality of mars inside the atmosphere? I really wish to see how mars looks inside with a good quality video which is colored, not black and white...
  
  Answer:-Mars already has two rovers, "Spirit" and "Opportunity". They have been operating on Mars' surface for about seven years, although Spirit may have recently gotten stuck in a cold location and poorly exposed to the Sun, and, subsequently, didn't get enough solar power to survive the last Martian winter.
  
  The next Mars rover, named "Curiosity", is scheduled for launch November 25, 2011.
• Question:-Will it be a lot more expensive (than the price of the mars rover) for NASA to send a rover?
  (like the mars rover)
  to Planet Jupiter's moon Europa to do some preliminary testing for possible life on Europa?
  
  Answer:-Yes, a Jovian Rover would have to be much tougher due to Jupiter's huge gravity and turbulent atmosphere. It would have to avoid being sucked into its atmosphere, on approach to Europa and would require lots of fuel. Then there is the electronic magnetic interpherence as most radioactive particles are drawn toward toward it so any electronic equipment would have to be well shielded.
• Question:-How did the Mars Rover get to Mars?
  Im just curious on how the Mars Rover got to Mars after it left Earth and how it knew which direction to go exactly for the 7 month period it was in space, cause outer space is a big place. Lol
  And how did it get to Mars since there is no control in space and you cant really move anywhere since theres no gravity, did it just float to Mars or was it powered by a rocket the entire time?
  
  Answer:-
• Question:-The Mars rover was deployed on the surface of Mars in July 1997.?
  The Mars rover was deployed on the surface of Mars in July 1997. At one point during its subsequent mission, radio signals took about 18 min to travel from Earth to the rover. How far was Mars from the from Earth at that time?
  
  Answer:-18 light minutes. (Just enter it into google for the conversion of units you want. I'll give you a hint, it's more than 300million KM (16 light minutes would be that... double the distance to the Sun).
• Question:-How was the mars rover balloon lander thing able to right itself after it deflates?
  i watched nasa sim of it and after the balloons deflate the rover comes out and voild --its right side up.
  
  ??
  sposed to say --"voila!"
  injanier --i didnt see the uprighting part in wiki --thanks!
  
  Answer:-The capsule that held the rover was a tetrahedron - four triangular sides, one of which was the base. A sensor on the lander figured out which face was down. If it wasn't the base, it opened the side that was facing down, which would flip the lander onto its base. Then the other sides open up and the rover can roll out.

• Question:-mirror mirror?
  There are 3 people standing in front of a magic mirror. The mirror gives you anything you desire if you tell it the truth, but you disappear if you lie. The first person to talk to the mirror was a very fat brunette. She walked up to the mirror and said "I think I am the thinnest person in the world." and poof, the mirror gobbled her up. The next person to come up to the mirror was a very ugly red head. She told the mirror "I think I am the prettiest person in the world" and poof, the mirror gobbled her up. Lastly came the blonde. She walked up to the mirror and said "I think..." and poof, the mirror gobbled her up.

• Question:-Are there such things as good mirror and bad mirror?
  I mean scientifically, is it possible to be a better mirror?
  
  Mirrors have different prices. What's the difference between cheap and expensive mirrors?
  
  Answer:-Yes, there are different classes of mirrors, depending on whether they are 'first' surface or 'second' surface; how reflective the mirror coating is, and (if it's a mirror like a telescope mirror) how accurate the curvature of the surface is.
  A 'second' surface mirror is like the one in your bathroom, where the mirror coating is on the back side (or second surface). A first surface mirror (like a telescope mirror) has the reflective coating on the first surface.
  Some mirrors use aluminum as the reflective coating. If not protected the aluminum will tarnish, so a more expensive coating uses 'protected' aluminum. Aluminum reflects about 90% of the light. A very expensive mirror might use exotic materials to boost the reflectivity to 98% or higher.
  For a telescope mirror the accuracy of the curved surface is measured in fractions of a wavelength. A 'one-quarter wave' mirror is the least expensive type. A 'one-tenth wave' mirror is more expensive, since it's accuracy is much greater.

  look at the backside of the mounting pad on your new mirror. it should show the underside of the screw.
• Question:-How to get through a house of mirrors/mirror maze?
  So I'm on vacation and there is a mirror maze. I went through it once and it was a lot harder than expected! Do you know of any techniques I can use to get through it really fast? I already tried only looking at the floor but it didn't help :/ Thank you!!
  
  Answer:-Right hand rule, keep your right hand in contact with the wall and always turn right. Supposed to work.
  
  Reference has lots of info.
  The wall follower, the best-known rule for traversing mazes, is also known as either the left-hand rule or the right-hand rule. If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the player is guaranteed not to get lost and will reach a different exit if there is one; otherwise, he or she will return to the entrance. This strategy works best when implemented immediately upon entering the maze.
  
  Another perspective into why wall following works is topological. If the walls are connected, then they may be deformed into a loop or circle. Then wall following reduces to walking around a circle from start to finish.
  
  If the maze is not simply connected (i.e. if the start or endpoints are in the center of the structure or the pathways cross over and under each other), this method will not be guaranteed to help the goal to be reached.
