Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
To view the latest “hi-res” images taken by MRO’s High Resolution Imaging Science Experiment (HiRISE) camera between April and August of 2009, please go to “Thousands of New Images Show Mars in High Resolution,” which is on the NASA Jet Propulsion Laboratory’s MRO website.
Each high-resolution image shows details as small as one meter (about three feet) across, with each image showing an area of land about six kilometers (3.7 miles) wide and 12 to 24 kilometers (7.4 to 14.8 miles) long.
The HiRISE camera consists of a 0.5-meter reflecting telescope, which has a resolution of 0.3 meters (about one foot) from an altitude of 300 kilometers (185 miles).
The MRO was launched from the Cape Canaveral Air Force Station, on the Florida coast next to the Kennedy Space Center, on August 12, 2005.
Launched from an Atlas 5-401 rocket at Launch Complex 41, the MRO spacecraft was then placed in an interplanetary transfer orbit toward Mars by a Centaur upper stage.
As it neared Mars, the MRO performed several thrusts that placed it in a nearly circular orbit about Mars--about 250 by 316 kilometers (155 by 196 miles) above the Martian surface.
The mission became operational around November 2006, after all of its scientific instruments were tested and verified to be working properly.
