Radio problems delay lander's work on Mars
NASA couldn't send commands to the Phoenix Mars lander for most of Tuesday because of a radio glitch, delaying a second day of activities, officials said.
The minor problem was fixed later in the day and the Mars Reconnaissance orbiter resumed relaying the lander's images of the Martian landscape back to Earth, said NASA officials.
Phoenix, the latest spacecraft on Mars, communicates with scientists through two NASA orbiters circling the planet.
The Reconnaissance turned its radio off, possibly because of a cosmic ray, said Fuk Li, manager of the Mars exploration program for NASA's Jet Propulsion Laboratory in Pasadena, California.
