Challenger Memorial
A stone monument (right) to the seven Challenger
astronauts is located in Arlington National Cemetery near Washington, D.C. The astronaut’s faces and
names are carved into a plaque on the stone. The
monument also includes the words of a famous
poem “High Flight.” John Gillespie Magee Jr. wrote
the poem in 1941. President Ronald Reagan
included phrases from Magee’s poem when he
honored the Challenger astronauts in 1986.

The Orion spacecraft—one of the new Constellation vehicles—will be ten times safer than the old space shuttles. For instance, if Orion’s main rocket explodes during launch, a small emergency rocket will blast the rest of Orion away from the explosion. Then a parachute will open. The parachute will slow Orion as it falls to the ground or water.

never be used.
The 1986 Challenger disaster offers an example of a safety lesson not
learned. Recovery workers think that some of Challenger’s astronauts survived the space shuttle explosion. They may have been alive when their cabin fell into the Atlantic Ocean. If the cabin had had an ejection system, like that used on military airplanes, the surviving crew members could have escaped the shuttle. The system could have shot them out of the wreckage. They could have floated to Earth usi
ng parachutes. After the Challenger and Columbia disasters, safety experts suggested installing ejection systems on space shuttles. But equipping space shuttles with ejection systems would be costly and very complicated. Some experts doubted that the systems could be made to work effectively. So NASA decided not to install ejection systems on space shuttles.

DODGING THE JUNK
No matter how safe future spacecraft may be, dangers will remain. Space junk will be one of the most serious problems. As more and more countries launch spacecraft and satellites, more and more space junk will zoom around Earth like bullets. However, engineers are also building more powerful radar systems. The new systems may be able to spot even the tiniest pieces of space junk.
YOUR FUTURE IN SPACE?
In the future, you may fly in space. You and your family may be able to orbit Earth on a passenger spaceliner. Several companies have started taking reservations for space tours. The companies will take people into space on private (nongovernment) spacecraft. How much will a ticket cost?
At least $200,000. A U.S. government agency, the Federal Aviation Administration, will make sure that private
