HOUSTON, Texas (CNN) -- Human remains found in a field in Texas late Saturday are believed to be those of at least one of the seven astronauts who perished aboard space shuttle Columbia when it disintegrated nearly 40 miles above the Earth.
Along with the remains, a charred NASA patch and a flight helmet were found on a rural road in Hemphill, east of Nacogdoches, Texas, according to The Associated Press. (Full story)
FBI agents in Texas are helping local authorities recover shuttle debris, FBI Dallas field office spokeswoman Lori Bailey told CNN.
Streaking through the atmosphere at 18 times the speed of sound, Columbia disintegrated Saturday morning about 15 minutes before its scheduled landing at the Kennedy Space Center in Florida. (Disaster timeline)
Those killed on the ill-fated shuttle flight were commander Rick D. Husband; pilot William C. McCool; payload commander Michael P. Anderson; mission specialists David M. Brown, Kalpana Chawla and Laurel Clark; and Israel's first astronaut, Ilan Ramon.
"Columbia's lost. There are no survivors," a grim-faced President Bush later said in an address to the American people. "These astronauts knew the dangers and they faced them willingly, knowing they had a high and noble purpose in life." (Full story)
With their voices sometimes threatening to break, NASA officials vowed they would find the cause of the disaster so their colleagues' sacrifice would not be in vain.
The Federal Emergency Management Agency, assisted by military forces from Fort Hood, Texas, have begun collecting debris from Columbia. People were urged not to go near the debris because it could contain toxic substances from the shuttle fuel.
To assist the recovery effort, the Federal Aviation Administration prohibited aircraft from flying below 3,000 feet in an area 160 miles long and 40 miles wide extending from Cedar Creek, Texas, to Fort Polk, Louisiana. The FAA also urged pilots and airlines to be alert to a debris cloud in the area -- 95 miles long and more than 22 miles wide -- that could create a "visibility issue" for pilots.
Witnesses in Texas reported debris falling from the sky, accompanied by a cascade of thunder.
"When it got nearer, we could see flecks or pieces coming off of it," said Linda Steed, who lives near Nacogdoches, Texas. She said the sound "reverberated" for several minutes, "like a rolling thunder."
"I'm devastated. It's unbelievable. It makes me so sad," she said. (Witness reports)
Heat-detecting weather radar showed a bright red streak moving across the wide Texas sky.
Reports of charred debris stretched from Corsicana, southeast of Dallas, into Louisiana, and could turn up as far east as Arkansas, and as far west as Arizona and New Mexico. More on debris found)
Officials asked anyone who finds shuttle debris to call (281) 483-3388.
Questions raised about foam piece that fell during launch
Even as they mourn for their seven friends and colleagues killed in the shuttle disaster, NASA officials have begun investigating why Columbia broke into pieces.
"My promise to the crew and to the crew families is that the investigation that we have just launched will find the cause, we'll fix it and then we'll move on. We can't let their sacrifice be in vain," said NASA associate Administrator Bill Readdy, a veteran of two shuttle flights. (Transcript)
Shuttle program manager Ron Dittemore said the first indication of trouble was loss of temperature sensors on the left wing. "They were followed seconds and minutes later by several other problems, including loss of tire pressure indications on the left main gear and then indications of excessive structural heating."
Officials said they will take another look at a piece of foam that came off during takeoff.
The fact that the foam struck the left wing, site of some of the sensors that failed Saturday, means that the incident will need to be investigated further, NASA chief flight director Milt Heflin said.
But Dittemore cautioned against jumping to conclusions, saying what looks like "the smoking gun" many times turns "out not even to be close."
"Is that the smoking gun?" he said. "It is not. We don't know enough about it. A lot more analysis and evidence needs to come to the table." (More on investigation)
A NASA official said the shuttle's altitude made it "highly unlikely" that it was a victim of a terrorist act. FBI officials also quickly discounted the possibility of foul play or terrorism. (Full story)
Space shuttle flights have been put on hold until NASA can learn what caused the disaster. NASA says the international space station, where two astronauts and a cosmonaut remain, has enough supplies to last the crew until June.

Columbia mission patch found alongside road in Texas
The next shuttle flight had been scheduled for March 1.
Columbia is the oldest of NASA's shuttle fleet, first launched in 1981. It was on its 28th mission. The shuttle underwent an extensive, 17-month overhaul that began in September 1999. (Columbia history)
It rejoined the shuttle fleet in February 2001 and flew its first mission after the upgrades in March 2002.
Columbia was lost less than a week after the anniversaries of two other deadly space program disasters -- the 17th anniversary of the explosion of the shuttle Challenger on January 28 and the 36th anniversary of a launchpad fire that killed three Apollo astronauts January 27. (Challenger disaster)

Basically the 90 degree stipulation is saying that to communicate, the ships have to be on the same half of the earth as each other. So the probability that the first two ships can communicate with each other is 1/2. The probability that the third ship can communicate with EITHER the first or the second ship is: 1 - (1/2 * 1/2) = 3/4 Therefore, the probability that all three ships can communicate with each other is: 1/2 * 3/4 = 3/8

Your probably thinking of the "Challenger". 14 Space Missions were cancelled after that disaster, pending investigations.
The space shuttle crew was seven. They were Ellisons Onizuka, Christa McAuliffe, Greg Jarvis, Judy Resnik, Mike Simth, Dick Scobee, and Ron McNair. This crew included the first civilian to join a NASA crew in space. She was a teacher, Christa McAuliffe.
The space shuttle Challenger explosion was caused by the leaking of the right solid rocket booster field joint. The flight lasted 76 seconds. There was nothing to indicate anything was amiss. The fire erupted and burned through the external tank. Then seconds after the tank ignited, the orbiter ripped apart.
Later that day NASA divers located the torn crew compartment. Somehow the bodies of the astronauts were still strapped into their seats. Even though the orbiter ripped open, it was not enough to have killed the crew. Crash investigators discovered that three of the crew had used air during the two mintues and 45 seconds while the crew compartment fell toward the sea.

The Columbia space shuttle was destroyed on re-entry because of a ripped heat shield. There was 7 astronauts on board, one of them was from a country who was sending thier first astronaut up. Only a couple of years ago.
There was also that other shuttle, the Challenger which was destroyed while going up back in the '80s. There was a school teacher aboard that one.

1. Space Shuttle Columbia (NASA Orbiter Vehicle Designation: OV-102) was the first space shuttle in NASA's orbital fleet. Its first mission, STS-1, lasted from April 12 to April 14, 1981. On February 1, 2003, Columbia disintegrated during re-entry on its 28th mission; all seven crew members aboard perished.
2. Space Shuttle Challenger (NASA Orbiter Vehicle Designation: OV-099) was NASA's second Space Shuttle orbiter to be put into service, after Columbia. Its maiden voyage was on April 4, 1983, and it made eight further round trips to low earth orbit before breaking up 73 seconds after the launch of its tenth mission, on January 28, 1986, killing all 7 crew members.
The Space Shuttle Challenger accident occurred on the morning of January 28, 1986, at 11:39 EST, when Space Shuttle Challenger disintegrated 73 seconds into its flight (at the start of mission STS-51-L, the 25th mission of the STS program and Challenger's 10th flight) owing to the failure of an O-ring seal in the aft (lower) segments of the right solid rocket booster (SRB).
The seal failure caused a flame leak from the SRB that impinged upon the adjacent external propellant tank and aft SRB connecting strut. Within seconds the flame caused structural failure of the external tank, and the orbiter broke up abruptly due to aerodynamic forces. The crew compartment and many other vehicle fragments were eventually recovered from the ocean floor.
3. Soyuz 11. During the reentry of the second flight, Soyuz 11, the crew were killed when the capsule depressurised during the re-entry phase.
4. Soyuz 1 (Russian Союз 1, Union 1) was part of the Soviet Union's space program and was launched into orbit on April 23, 1967, carrying a single cosmonaut, Colonel Vladimir Mikhailovich Komarov, who was killed when the spacecraft crashed during its return to Earth due to parachute failure. This was the first in-flight fatality in the history of manned spaceflight. Launched at 3:35am local time, this was also the first night launch of a manned space vehicle.
