New Mars Lander Looks for Water, Old Signs of Life (Science/Technology, 6 articles)
|
Space entrepreneurs eyeing Mars as a hub of some future solar system economy launched a startup on Tuesday to mine the red planet for building materials. On Sunday, May 25, the Mars Phoenix Lander will plunge through the red planet's atmosphere in search of water and possibly look for evidence of life on Mars. In less than two weeks, the Mars Phoenix Lander could realize scientists' long-delayed dream of directly finding Martian ice for the first time. If NASA one day fulfills the dream of sending a manned expedition to Mars, Reid Stowe will have plenty of advice for the first astronaut crew. Its landing site is in a region where NASA's orbiting Mars Odyssey spacecraft has detected gamma-ray and neutron signatures suggesting a significant amount of hydrogen - thought to be a constituent of frozen water - near the surface. Soon after unfurling twin solar arrays, the lander will extend a robotic arm to dig down as far as half a metre in search of that ice. Older missions, including the rovers Spirit and Opportunity, have shown that there was water at and near the planet's surface billions of years ago.

Google helps the web to go social (Science/Technology, 5 articles)
|
Google has ramped up its sales force in the Washington area in the past year to adapt its technology products to the needs of the military, civilian agencies and the intelligence community. Agencies use enhanced versions of Google's 3-D mapping product, Google Earth, to display information for the military on the ground in Iraq and to track airplanes that fight forest fires across the country. The giant Internet search company, which hired its first Beantown Googlers at the end of 2005 and had 50 people working out of the Cambridge Innovation Center just a year ago, has expanded to 175 local employees.
