I dont have much info about fuel consumption nd generation but could someone plz explain how did it manage to travel for more than 8 months nd would now spend 2 years there without any external fuel supply? One of the genius here on this forum discovered a photograph of self charging laptop cable nd is posting it everywhere on forum so r we safe to assume that this curiosity shutle or watever recharges itself? May b it uses solar energy but it cant depend on it completely sO if someone knows the answer plz share it thanks v r still praising the hoax of moon landing lets c wat happens to this one nd could the blind believers on american technology plz explain why they chose mars this time nd not moon?

It orbited the earth build up speed than thrown towards Mars like a sling shot. It only has fuel for landing and to keep the equipment inside charged and to make correction in trajectory. Its the gravity of Mars that pulls it.

While on Mars I believe it uses solar panels but I am not all sure.

Why they chose Mars over Moon? I believe there is lot more mystery locked in Mars since its a planet similar to earth. It has four seasons has a similar tilt towards Sun it also have a similar rotation around its axis like earth and have day and night similar to Earth. A polar ice cap and some evidence that it had flowing water on surface at some time. It has mountains and had active volcanoes.

The rover is powered by an on-board nuclear generator.
http://mars.jpl.nasa.gov/msl/mission/rover/energy/

The Mars Science Laboratory rover carries a radioisotope power system that generates electricity from the heat of plutonium's radioactive decay. This power source gives the mission an operating lifespan on Mars' surface of at least a full Martian year (687 Earth days) or more while also providing significantly greater mobility and operational flexibility, enhanced science payload capability, and exploration of a much larger range of latitudes and altitudes than was possible on previous missions to Mars.

Here is a fact sheet of how the generator works:http://www.ne.doe.gov/pdfFiles/MMRTG_Jan2008.pdf


The battery pack has an estimated time of running for one Martian year (687 days) but NASA will power down the rover at night and will only use it during the day so that gives it a life time of 2 years of power.

The hoax of the moon landing is a conspiracy theory without any conclusive proof.

Missions to Mars have been going on for a long time not only by the US but also by the Russians.
The Russians landed on Mars before the US.

Heres a timeline:

You might not know but the Russians had also sent a mission to Venus and today the only existing images of the surface of Venus are from the Russian Venera missions in the 70s and 80s.

[h=3]The Promised Land[/h]This image (cut out from a mosaic) shows the view from the landing site of NASA's Curiosity rover toward the lower reaches of Mount Sharp, where Curiosity is likely to begin its ascent through hundreds of feet (meters) of layered deposits. The lower several hundred feet (meters) show evidence of bearing hydrated minerals, based on orbiter observations. The terrain Curiosity will explore is marked by hills, buttes, mesas and canyons on the scale of one-to-three story buildings, very much like the Four Corners region of the western United States.

A scale bar indicates a distance of 1.2 miles (2 kilometers).

Curiosity's 34-millimeter Mast Camera acquired this high-resolution image on Aug. 8, 2012 PDT (Aug. 9 EDT).

This image shows the colors modified as if the scene were transported to Earth and illuminated by terrestrial sunlight. This processing, called "white balancing," is useful to scientists for recognizing and distinguishing rocks by color in more familiar lighting.

Flex, Zap, Roll: NASA's Curiosity Mars rover performs a series of firsts this week -- flexing its arm, laser-zapping a rock and rolling on its wheels. See the rover's landing site, named for author Ray Bradbury on the day that would have been his 92nd birthday.

[h=3]Marks of Laser Exam on Martian Soil[/h]The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser to examine side-by-side points in a target patch of soil, leaving the marks apparent in this before-and-after comparison.

The two images were taken by ChemCam's Remote Micro-Imager from a distance of about 11.5 feet (3.5 meters). The diameter of the circular field of view is about 3.1 inches (7.9 centimeters).

Researchers used ChemCam to study this soil target, named "Beechey," during the 19th Martian day, or sol, of Curiosity's mission (Aug. 25, 2012). The observation mode, called a five-by-one raster, is a way to investigate chemical variability at short scale on rock or soil targets. For the Beechey study, each point received 50 shots of the instrument's laser. The points on the target were studied in sequence left to right. Each shot delivers more than a million watts of power for about five one-billionths of a second. The energy from the laser excites atoms in the target into a glowing state, and the instrument records the spectra of the resulting glow to identify what chemical elements are present in the target.

The holes seen here have widths of about 0.08 inch to 0.16 inch (2 to 4 millimeters), much larger than the size of the laser spot (0.017 inch or 0.43 millimeter at this distance). This demonstrates the power of the laser to evacuate dust and small unconsolidated grains. A preliminary analysis of the spectra recorded during this raster study show that the first laser shots look alike for each of the five points, but then variability is seen from shot to shot in a given point and from point to point.

ChemCam was developed, built and tested by the U.S. Department of Energy's Los Alamos National Laboratory in partnership with scientists and engineers funded by France's national space agency, Centre National d'Etudes Spatiales (CNES) and research agency, Centre National de la Recherche Scientifique (CNRS).

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the Mars Science Laboratory Project, including Curiosity, for NASA's Science Mission Directorate, Washington. JPL designed and built the rover.
