CAPE CANAVERAL, Florida (AP) -- NASA lost communication with space shuttle Columbia shortly before its scheduled landing on Saturday. It was unclear whether there were any other problems.
Mission Control reported no communication with the shuttle after 9 a.m. EST.
The shuttle was carrying the first Israeli astronaut and six Americans, and authorities had feared it would be a terrorist target.
Fifteen minutes after the expected landing time, and with no word from the shuttle, NASA announced that search and rescue teams were being mobilized in Dallas and Fort Worth areas.
NASA, while not saying the shuttle had exploded, broken up or crashed, warned that any debris found in the area should be avoided and could be hazardous.
Inside Mission Control, flight controller hovered in front of their computers, staring at the screens. The wives, husbands and children of the astronauts who had been waiting at the landing strip were gathered together by NASA and taken to separate place.
Columbia was at an altitude of 200,700 feet over north-central Texas at a 9 a.m., traveling at 12,500 mph when mission control lost contact and tracking data.
Reporters at the landing strip were ordered away 7 minutes after the scheduled touchdown with still no sign of the shuttle.
In 42 years of human space flight, NASA has never lost a space crew during landing or the ride back to orbit. In 1986, space shuttle Challenger exploded shortly after liftoff.
Security had been tight for the 16-day scientific research mission that included the first Israeli astronaut.
Ilan Ramon, a colonel in Israel's air force and former fighter pilot, became the first man from his country to fly in space, and his presence resulted in an increase in security, not only for Columbia's January 16 launch, but also for its landing. Space agency officials feared his presence might make the shuttle more of a terrorist target.
On launch day, a piece of insulating foam on the external fuel tank came off during liftoff and was believed to have struck the left wing of the shuttle. NASA said as late as Friday that the damage to the thermal tiles was believed to be minor and posed no safety concern during the fiery decent through the atmosphere.
Science mission
Columbia's crew -- Ramon and six Americans -- completed all of their 80-plus experiments in orbit.
They studied ant, bee and spider behavior in weightlessness as well as changes in flames and flower scents, and took measurements of atmospheric dust with a pair of Israeli cameras.
The 13 lab rats on board -- part of a brain and heart study -- faced the guillotine following the flight so researchers could see up-close the effects of so much time in weightlessness.
The insects and other animals had a brighter, longer future: the student experimenters were going to get them back and many of the youngsters planned to keep them, almost like pets.
All of the scientific objectives were accomplished during the round-the-clock laboratory mission, and some of the work may be continued aboard the international space station, researchers said.
The only problem of note was a pair of malfunctioning dehumidifiers, which temporarily raised temperatures inside the laboratory to the low 80s, 10 degrees higher than desired.
Some of Columbia's crew members didn't want their time in space to end.
"Do we really have to come back?" astronaut David Brown jokingly asked Mission Control before the ride home.
