U.S. to shoot down disabled satellite
Feb. 14: U.S. officials say that the Defense Department will shoot down a disabled spy satellite that is expected to hit Earth in March. NBC's Jim Miklaszewski reports.
U.S. military officials told NBC News a U.S. Navy ship is preparing to launch a missile over the Pacific Ocean Wednesday night in an attempt to shoot down a dead spy satellite.
If all goes as planned, the Aegis cruiser USS Lake Erie will launch the SM-3 tactical missile at about 10:30 p.m. ET from about 600 miles northwest of Hawaii.
The spy satellite lost all power almost immediately after it was launched into space in December 2006. Without power, the 5,000-pound satellite, about the size of a school bus, would be expected to make an uncontrolled reentry into the atmosphere and crash in early March.
Although half the satellite would be expected to burn up on reentry, U.S. officials fear that the 1,000 pounds of potentially deadly hydrazine fuel on board pose a risk to people on the ground. Military and NASA officials say because of that threat the decision was made to attempt to destroy the satellite in space.
The three-stage SM-3 missile carries a "kinetic-kill" warhead that employs infrared sensors to guide it to the target. With no explosives, the warhead must slam into the target at a closing speed of 22,000 mph to destroy the satellite 130 miles above Earth.
U.S. loses control of spy satellite
Jan. 28: A U.S. intelligence agency loses control of a spy satellite after it loses power. NBC's Tom Costello has the details.

Since the satellite has no power, the intercept must occur at a precise time when the sun's rays actually heat the satellite so the warhead's infrared sensors can detect and target the satellite. Classified computer software also will aim the warhead directly at a specific point on the satellite to hit the hyrdrazine fuel tank itself. From the launch to the intercept and kill should take about a minute and a half.
Since the satellite would be destroyed in a low orbit, U.S. officials say most of the debris would fall harmlessly through the atmosphere and not orbit the Earth as space junk.
The satellite, designated US 193, belongs to the highly-secretive National Reconnaissance Office and is loaded with sensitive, top-secret imaging devices.
U.S. officials deny, however, that the decision to destroy the satellite in space was an effort to keep the classified material from falling as debris into the hands of the Russians or Chinese.
