On May 25, 2012 at 1500 UTC (11 a.m. EDT/U.S.), Typhoon Sanvu had maximum sustained winds near 60 knots (69 mph/111 kph), slightly weaker than it was on May 24. Typhoon-force winds cover a compact area, extending 25 miles (40 km) from the center, while tropical storm-force winds extend as far as 150 miles (241.4 km) from the center, making the storm over 300 miles (~483 km) in diameter.

NASA satellites are providing rainfall, temperature, pressure, visible and infrared data to forecasters as Hurricane Bud is expected to make a quick landfall in western Mexico this weekend before turning back to sea. NASA's TRMM and Aqua satellites have been flying over Bud as it nears the Mexican coast.

Scientists with the University of Arizona-led asteroid sample return mission OSIRIS-REx have measured the orbit of their destination asteroid, 1999 RQ36, with such accuracy they were able to directly determine the drift resulting from a subtle but important force called the Yarkovsky effect – the slight push created when the asteroid absorbs sunlight and re-emits that energy as heat.

Tropical Storm Sanvu strengthened overnight as forecast and is now a Typhoon in the western North Pacific Ocean. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite observed that most of the rainfall is falling in the eastern half of the storm.

Bud has now become the first hurricane of the eastern Pacific Hurricane Season, as NASA visible and infrared satellite imagery revealed an organized structure of spiraling thunderstorms around the eye. Watches and warnings are already in effect for southwestern Mexico as Bud nears.

Two NASA satellites have provided infrared and rainfall data that has shown Tropical Storm Sanvu continues to intensify as it heads toward Iwo To, Japan. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite has scanned rainfall rates, and NASA's Aqua satellite has provided a look at cloud temperatures which indicates where the strongest thunderstorms and heaviest rainfall is occurring.

NEW YORK, May 25, 2012 – Ben-Gurion University of the Negev (BGU) researchers have created a man-made oasis in the desert with the successful application of a solar-powered desalination system that provides water for irrigation in arid regions. The project was made possible with support from American Associates, Ben-Gurion University of the Negev (AABGU).

Washington, DC — Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously been found in meteorites from Mars, scientists have disagreed about how this organic carbon was formed and whether or not it came from Mars.
