It began its primary mapping mission on March 8, 1999. Mars Global Surveyor is the first mission in a long-term program of Mars exploration known as the Mars Surveyor Program that is managed by JPL for NASA's Office of Space Science, Washington, DC. Malin Space Science Systems (MSSS) and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO. |

Do you think that Mars might be undergoing global warming.
I was just looking at .. http://www.msss.com/mars_images/moc/...6.S1100815.gif from http://www.msss.com/mars_images/moc/2006/02/16/ The ice must be sublimating into the atmosphere. There are no melt fluid run off channels. Isn't there occasionally suggestions of run-off channels going down the side of some craters in sedimentary formations. See also http://www.msss.com/mars_images/moc/...9.S1100677.gif Thanks for the interesting posting Ron. Why don't you ever write any chatty stuff? We could use some global warming up here in chilly Ottawa. Best, Michael |

We could use some global warming up here in chilly Ottawa. Best, Michael Hi Mike. First of all, water-scoured channels on Mars appear to be old, very old. Mars's atmosphere is not currently dense enough to support liquid water, and hasn't been for billions of years. Any ice that melts sublimates immediately into the gaseous phase. There have been suggestions of groundwater erupting along the sides of craters, but this has not been definitely verified. Secondly, what you are seeing in the first image in the link you posted is likely a result of sublimation that normally occurs during the martian polar summers. I've read that there is evidence that the polar ice caps were once much larger than they are today. Since they are now smaller, obviously, the planet has warmed up since that time. As to whether that indicates that global warming is currently an ongoing phenomenon, I've seen no published papers that indicate that this is the case. George |

Oh really? http://panteltje.com/panteltje/space...lake2color.jpg from: Link not currently working. http://sci.esa.int/science-e/www/obj...objectid=34508 more detail, true color: Not true color. It is an RGBi image, taken with color filters. http://www.esa.int/SPECIALS/Mars_Exp...BQXLDMD_0.html Yes, the images have been processed but that is quite normal. We are not taking colour photographs, we have to combine the different colour channels which requires processing time. Each of the four colour channels operate with a filter of different wavelength (red, green, blue and infrared) and produce data sets which have to be combined and calculated on to a digital elevation model. The colour channels are absolutely real, but they do not reflect the true colour as we would see it with our eyes. These views can be obtained by processing the data, which does not mean 'faking' the colours, but fitting them to standard spectral curves which we know. We adjust the obtained colour image data to a standard spectral curve derived from Earth-based observations in terms of wavelength and intensity. Secondly, if you read the fine print of the caption, it says "once formed by water". There is currently no running water there, Pantie. sorry. http://panteltje.com/panteltje/space...olordetail.jpg If you write stuff, add 'I think' or 'I repeat current concepts'. But LOOK. If I write stuff, I stand by them until someone disproves them. I'm still waiting. |

It is an RGBi image, taken with color filters. Look up the discussion in sci.astro about this, this camera, the processing, the scanning method and the filters AND THIS PICTURE with somebody from ESA and me. Then learn about cameras, electronics, pictures in general and how to click on a link.

Secondly, if you read the fine print of the caption, it says "once formed by water". There is currently no running water there, Pantie. sorry. I read the fine print BETWEEN THE LINES in all publications that says: THERE IS ONLY LIFE ON EARTH AND JESUS SAVES. Even the Spanish when they went to the Americas went to convert the inhabitants. If it turned out the rest of the universe (which is actually MUCH bigger then your back garden) has life that is not Christian, Muslim, Hindu or Buddha related, that MIGHT just have people think twice about the current 'heaven later' scum, and have them go for heaven now. In my view it is only for the extrememly lucky and those whe want to see, not what they have been tought they do see, but really see. I qualify in the case of electronics, cameras, colormeterics and picture processing to say: It is a lake with water. Your postings sucks. And that is also a qualified opinion. Byeeeeee! |
