QUOTE The plumes of methane appeared over northern hemisphere regions such as east of Arabia Terra, the Nili Fossae region, and the south-east quadrant of Syrtis Major, an ancient volcano 1,200 kilometers (about 745 miles) across If you do Mars Google, I found the three regions to be about the same northern latitud. However, Syrtis and Nili Fossae are very close and Arabia Terra is about 3,000 kilometers west of the first ones. The other thing, I have observed the methane distribution thru the APOD picture and found that the plumes are not uniformily distributed all planet but localized mostly in that zone. Is that methane distribution consistent in spite of the fact its intensity varies with the seasons. These many questions might be solved with the future orbiters with adequate instruments to detect the methane. MSL will have it but it won't see all Mars. Hence, the Nili Fossae would be considered again as the one of the four potentials landings. |
