The United States marked the 30th anniversary Thursday of the explosion of the Challenger space shuttle with a pledge to remember lost astronauts as it presses on toward Mars.
At the Kennedy Space Center in Florida, where the shuttle blasted off on January 28, 1986, singers in red and blue belted out the Star Spangled Banner for a crowd that included relatives and friends of the seven killed that day.
Six NASA astronauts and Christa McAuliffe—who would have been the first teacher in space—died when the shuttle exploded 73 seconds after liftoff.
The cause was a failed booster engine, according to the US space agency.
"These brave women and men are forever a part of a story that is ongoing, " President Barack Obama said in a statement.
"It is a story that will bring human beings to Mars and out into our solar system—and beyond. It is a story made possible by their sacrifice and heroism."
Wreaths were laid at Arlington National Cemetery near the US capitol as NASA commemorated the 24 US lives lost in space disasters and test flights over the years.
"As we undertake a journey to Mars, they will be with us. They have our eternal respect, love and gratitude, " said a statement by NASA administrator Charles Bolden, a former astronaut.NASA picture shows the crew of the doomed US space shuttle Challenger.

"On this solemn occasion, we pause in our normal routines and remember."
The other major shuttle accident was on February 1, 2003. Seven people died aboard the Columbia shuttle when it broke into pieces while re-entering Earth's atmosphere.
NASA said later that a piece of foam had come loose from the external tank during launch, and formed a hole in one of the shuttle's wings, causing it to break up 16 minutes before it was to have landed.The crew of US space shuttle Columbia (front: L-R) William McCool, Rick Husband, (second row, L-R) Kalpana Chawla, Laurel Clark, (third row, L-R) Ilan Ramon, Michael Anderson and David Brown

The US space agency also commemorated the three men who died in the Apollo 1 launch pad fire in 1967, before the nation ever made it to the moon.
"Remembering the crews today that we've lost, especially my best friend Ed White who perished in the Apollo 1 fire, " astronaut Buzz Aldrin—the second person to step foot on the Moon after American astronaut Neil Armstrong—said on Twitter.The crew of Apollo 1 at the Kennedy Space Center, (from L) Virgil Grissom, Edward White, and Roger Chaffee
Bolden also recalled the 1967 loss of Mike Adams who died on an X-15 hypersonic rocket-powered aircraft, and others who perished in "test flights and aeronautics research throughout our history."
Shortly after taking office, Obama cancelled a NASA program to return to the moon, saying he preferred to funnel resources into deep space exploration and aimed to have a human mission to Mars under way by the 2030s.
The space shuttle program was formally ended in 2011 after three decades of ferrying astronauts to and from low-Earth orbit.See also:
