MSL is scheduled to liftoff at 10:02 a.m. EST on Nov. 26 from Space Launch Complex 41 at nearby Cape Canaveral Air Force Station (CCAFS). NASA Television's countdown launch commentary begins at 7:30 a.m. on Nov. 26. That also is when a NASA blog will begin providing countdown updates. Originating from CCAFS Hangar AE, the blog is the definitive Internet source for information leading up to liftoff. Detailed lists of news briefing times and participants, prelaunch media tours and photo opportunities and hours of operation for Kennedy's press site are available at: http://www.nasa.gov/mission_pages/msl/news/index.html The Curiosity rover has 10 science instruments to search for evidence about whether Mars had environments favorable for microbial life, including the chemical ingredients for life. The rover will use a laser to look inside rocks and release their gasses so its spectrometer can analyze and send the data back to Earth. Free wireless Internet access currently is not available at Kennedy's press site. Media representatives must bring their own equipment for wireless connectivity.
