Drifting satellite threatens US cable programming
(AP) -- A TV communications satellite is drifting out of control thousands of miles above the Earth, threatening to wander into another satellite's orbit and interfere with cable programming across the United States, the ...
Space: The final frontier for cell phones?
(AP) -- The vast, thinly populated expanses of the country that still lack cell phone coverage could be getting an interesting option next year: ordinary-looking cell phones that connect to a satellite when ...
Third time a charm: SpaceX launches commercial satellite (Update 3)
The private US company SpaceX said it successfully launched on Tuesday its first commercial satellite, designed to provide telecommunications services to China and other Asian countries.
How astronauts can explore the Martian moon Phobos
Humans would spend more than a year orbiting and bouncing on the Martian moon Phobos under a mission concept developed by students at the International Space University.
Lightning strokes can probe the ionosphere
(Phys.org) —Thunderstorms, and the resulting partially ionized plasma of the ionosphere, can distort radio signals traveling to satellites important to communications, navigation or national security
After another near miss, professor wants to find asteroids that threaten Earth
(Phys.org) —On Saturday, an asteroid the size of one and a half football fields flew within 240,000 miles of Earth. If the space rock had hit land, it would have leveled an area the size of San Francisco ...
150-foot asteroid will buzz Earth, no need to duck (Update 2)
A 150-foot(45-meter)-wide asteroid will come remarkably close to Earth next week, even closer than high-flying communication and weather satellites. It will be the nearest known flyby for an object of this ...
US company aims to 'harvest' asteroids
A US company said Tuesday it plans to send a fleet of spacecraft into the solar system to mine asteroids for metals and other materials in the hopes of furthering exploration of the final frontier.
US military looks for new life for dead satellites
It's like doing robotic surgery in zero gravity: Imagine scavenging defunct communication satellites for their valuable parts and recycling them to build new ones for cheap.
