Starts alongside Jarvis Jones. Wears No. 124~126.
Gives things mass/destroys. Causes "an excess of events."
A journey from Earth to Mars could soon take just 39 days, cutting current travel time nearly six times, a rocket scientist who has the ear of the US space agency NASA has said.
Former astronaut Franklin Chang-Diaz, a physicist at the Massachusetts Institute of Technology, says reaching the Red Planet could be dramatically quicker using his high-tech VASIMR rocket -- now on track for lift-off after decades of development.
The Variable Specific Impulse Magnetoplasma Rocket -- to give its full name -- is quick becoming a centerpiece of NASA's future strategy as it looks to private firms to help meet the astronomical costs of space exploration.
An instrument aboard Messenger sampled Mercury’s surface composition by catching some of the charged atoms that have been knocked into space. Silicon, sodium and sulfur were detected. So was water.
“Which is a real surprise,” said Thomas H. Zurbuchen, an associate professor of atmospheric, oceanic and space sciences at the University of Michigan and lead author of another paper in Science. “The first time we took a whiff of the planet, it’s right there.”
One possibility is that the water exists as ice in the shaded parts of craters in the polar regions.
Barring a cloud cover, the International Space Station will be visible to the naked eye tonight between 9:01 and 9:07 p.m.
The space station should be directly overhead and be one of the brightest things in the sky, said Jim Greenhouse, director of marketing at the Museum of Arts and Sciences.
“The whole world around us lay spread out like a giant relief map,” he told one interviewer. “I am a lucky man. I have had a dream and it has come true, and that is not a thing that happens often to men.”
NASA's MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) probe will make a close approach to Mercury on Monday, one of three scheduled passes before slipping into a stable orbit around the hot planet in 2011.
The probe will be the first to enter orbit there, although the Mariner 10 previously visited the planet in the mid-1970s. But with an approach as close as 124 miles this time, MESSENGER will be able to send back more data, and images of higher resolution, than were achieved by the earlier craft.
