CAPE CANAVERAL, Fla. -- Flowers left at the base of the Space Mirror memorial by guests to the Kennedy Space Center Visitor Complex frame the names of the STS-107 crew lost in the Columbia tragedy.

Although the anniversary ceremonies are now in the past, the effort to remember the astronauts lost in pursuit of exploration continues in a big way thanks to Boeing.

The aerospace giant announced this week that company officials have decided to donate $1 million during the next few years to the Challenger Center as a living memorial to the crews lost in the Columbia and Challenger disasters.

The Challenger Center is an official educational partner with NASA and provides programs for teachers to help them teach math and science, as well as programs for students intended to encourage an interest in math and science.

"Boeing's gift will ensure that the half a million students and teachers served each year across the country will receive the quality teaching materials they deserve," said June Scobee Rodgers, founding chairman of the Challenger Center for Space Science Education, and widow of Challenger skipper Dick Scobee.
