China is currently putting all their effort into making sure the weather is perfect for the 2008 Summer Olympics Opening Ceremonies in Beijing. In fact, the Chinese government guarantees clear skies. What makes them so confident that there won’t be rain? The answer is a weather modification process called “cloud seeding” that China is heavily invested in.
Where's Mars Phoenix Landing?
The Phoenix Mars Lander is estimated to arrive on Mars on May 25, 2008. NASA has conditionally approved a landing site in a broad, flat valley known as "Green Valley," that has the largest concentration of ice on Mars outside of the polar caps. Phoenix will dig into an ice-rich layer of the surface, analyze the water and soil for evidence about climate cycles, and investigate whether the environment there has been favorable for microbial life. For more information about Phoenix Mars Lander, log in and visit the Space Library®.
The mission has already completed one trajectory correction, and has three more planned opportunities for maneuvers before May
25 to further refine the trajectory for a safe landing at the "Green Valley." For more information about trajectory corrections, log in and try the Trajectory Correction Interactive Applet.
