  ON THE MORNING OF FEBRUARY 1, 2003, SEVEN ASTRONAUTS WERE

  RETURNING TO EARTH AFTER A LONG TRIP. THE MEN AND WOMEN HAD

  BEEN IN SPACE FOR SIXTEEN DAYS. THEY HAD TRAVELED 6.6 MILLION

  MILES (10.6 MILLION KILOMETERS) ON THE SPACE SHUTTLE COLUMBIA.

  THE ASTRONAUTS’ FAMILIES WERE WAITING FOR COLUMBIA TO LAND AT

  THE JOHN F. KENNEDY SPACE CENTER IN FLORIDA. MILLIONS OF OTHER

  PEOPLE WERE WATCHING ON TELEVISION.

  Columbia was flying at 12,500 miles (about 20,112 km) per hour. It was 39 miles (63 km) above Texas. As Columbia neared Earth, the air that surrounds our planet rubbed against the craft causing friction. As Columbia got closer and closer to Earth, the rubbing increased. It made the outside of the shuttle heat up. It glowed red hot, like charcoal in a barbecue grill.

  began to melt.

  On the ground, mission controllers tracked

  the shuttle using radio signals and computers.

  They saw that one of the shuttle’s tires had

  gone flat. About the same time, Columbia

  commander Rick Husband sent a radio

  message to mission control. But controllers

  could not hear Husband clearly.

  eastern Texas in April 2003.

  Those were the last words from Columbia’s

  astronauts. After that, mission control heard only radio noise and crackling sounds. The shuttle had begun to break apart.

  People on the ground in Texas saw the disaster as it happened. Some reported seeing a ball of fire in the sky. Others saw the craft break into pieces. The pieces spiraled down to the ground.

  All seven astronauts died in the disaster. Columbia, which had cost more than $1.2 billion to build, was completely destroyed. Andy Gallacher, a British reporter, was in Texas when Columbia fell to Earth. He described the scene afterward. “The school playing field is scattered with wreckage, from charred [burned] pieces of metal the size of a finger nail, to large chunks,” he said. “The children of two farmers found the remains [body] of one crew member.” With the loss of the expensive shuttle and the deaths of all seven crew members, the Columbia accident was one of the worst space disasters in history.

  SPACE DISASTERS ARE SERIOUS ACCIDENTS INVOLVING SPACECRAFT. THE

  ACCIDENTS INCLUDE EXPLOSIONS AND FIRES. SOME SPACE DISASTERS HAVE

  HAPPENED IN SPACE. OTHERS HAVE OCCURRED DURING TAKEOFFS AND

  LANDINGS. SPACE DISASTERS HAVE KILLED MANY ASTRONAUTS. SPACE

  DISASTERS HAVE ALSO KILLED PEOPLE WORKING NEAR SPACECRAFT.

  four U.S. space shuttles. Building a

  replacement would have cost $3 billion.

  After a space disaster, nations with

  space programs usually delay other

  spaceflights. Workers must check other

  spacecraft to make sure they are safe.

  After the Columbia disaster, the United

  States grounded (kept on the ground)

  the three other space shuttles. It took

  workers more than two years to make

  sure the three shuttles were safe. The

  repairs and delays cost billions of dollars.

  HOW MANY DEATHS?

  Nobody knows how many space disasters have happened. Years ago, the former Soviet Union (based in modern-day Russia) kept space disasters a secret. Soviet leaders thought that news of space disasters would embarrass their country. But we do know that from the time spaceflight began in the 1950s, space disasters have killed at least twenty-one astronauts. More than 150 workers on the ground have also died in space disasters. Other workers have been injured.

  The number of deaths seems small compared to an airplane crash, which can kill hundreds of people at once. However, the death toll is actually quite large because very few people have flown in space. In fact, disasters have killed almost 5 percent of people who have ever flown in space. Imagine if accidents

  killed 5 percent of the

  people—one in every twenty—

  who ever rode in cars.

  In the United States and Europe, men and

  women who fly in space are called

  astronauts. The word comes from the Greek

  words astron (star) and nautes (sailor).

  Russians call their space travelers

  cosmonauts, meaning “universe sailors.”

  The Chinese use the word

  MORE DISASTERS AHEAD?

  In the United States, an agency called the National Aeronautics and Space Administration (NASA) oversees spaceflight and exploration. NASA works to make sure that spaceflights are safe.

  But despite safety precautions, more space disasters will probably take place in the future. More and more countries are starting space programs and building spacecraft. Some private companies plan to take tourists into space. Someday thousands of people might fly into space on passenger flights. As the number of passengers and flights increases, so will the chances that disaster will strike.

  Mars Monster?

  When people count up space disasters, they include only accidents involving humans. But disaster can also strike unpiloted spacecraft (spacecraft that don’t carry people). These spacecraft use cameras and scientific instruments to explore faraway planets and other parts of space. Space workers control the spacecraft from Earth with radio signals and computers.

  Many unpiloted missions to Mars—the Red Planet—have ended in disaster.

  In fact, almost three out of every four spacecraft sent to the Red Planet have failed. Some of the spacecraft crashed. Others did not work properly.

  Some just disappeared. Space workers joke about the Great Galactic Ghoul—a Martian monster that eats spacecraft.

  One of the monster’s last meals was the Beagle 2 (left).

  This unpiloted British spacecraft tried to land on

  Mars in 2003. However, the Beagle disappeared without a trace. The spacecraft stopped

  sending radio signals to Earth. No one

  knows its fate.

  WHY DO SPACE DISASTERS HAPPEN? THERE ARE SEVERAL REASONS. THE

  FIRST IS MECHANICAL ERROR—THE FAILURE OF PARTS OR EQUIPMENT ON

  THE SPACECRAFT. THE SECOND IS HUMAN ERROR, OR MISTAKES BY PEOPLE.

  MISSIONS, CAN HIT A TRAVELING SPACECRAFT, WITH DISASTROUS RESULTS.

br />   WHEN MACHINES FAIL

  Spacecraft are complicated machines. A space

  shuttle, for instance, has more than 2.5 million

  parts. It has 230 miles (370 km) of electrical

  wiring inside. It has almost one thousand

  valves that open and close to let liquids and

  gases flow through. More than twenty-seven

  thousand pieces of insulation protect a space

  shuttle from heat. During a spaceflight, all the

  parts and pieces must work correctly. Valves

  must open and close at exactly the right time.

  Hatches must close tightly.

  Space shuttles must withstand very cold and

  very hot temperatures. In space, shuttles fly

  in temperatures as low as –250°F (–157°C).

  When landing back on Earth, shuttles get red

  hot—up to 3,000°F (1,649°C).

  The space shuttle:

  How it Works and What Goes Wrong

  During the Columbia launch in 2003, a small piece of insulating foam broke off from the external fuel tank. The foam struck the orbiter’s left wing, damaging some insulating tile. During reentry, hot gases leaked through the damaged tile into the left wing.

  The shuttle burned and blew apart.

  The external fuel tank holds fuel for

  the shuttle’s main engines. About

  70 miles (113 km) above Earth, the

  shuttle jettisons, or releases, the

  tank. Most of it disintegrates in the

  atmosphere. The rest of it falls into

  the ocean.

  The solid rocket boosters

  propel the shuttle into

  space. Approximately 28

  miles (45 km) above Earth,

  the boosters separate from

  the rest of the shuttle.

  They descend by parachute

  into the ocean. NASA

  reuses the boosters.

  The orbiter holds the

  shuttle’s crew, cargo,

  living spaces, and

  work spaces.

  During the Challenger launch in 1986, hot gases leaked from the right rocket booster. The gases

  burned a hole in the external fuel tank. The fuel

  tank exploded. The shuttle tore apart, and the

  orbiter smashed into the ocean.
