Kennedy Space Center Director and former astronaut, Bob Cabana, remembers our fallen heroes at the Day of Remembrance ceremony.
Washington, United States:
The US space agency marked the 30th anniversary Thursday of the explosion of the space shuttle Challenger 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 outfitted in red and blue belted out the Star Spangled Banner for a crowd that included relatives and friends of the seven killed that day.
"The Challenger crew will forever be young, and will never be forgotten," said Bob Cabana, a former astronaut and director of the Kennedy Space Center.
"They continue to motivate us to explore."
A wreath-laying ceremony was planned for Arlington National Cemetery in Virginia 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.
"On this solemn occasion, we pause in our normal routines and remember."
Six NASA astronauts and Christa McAuliffe -- who would have been the first teacher in space -- were killed in the Challenger disaster, when the shuttle exploded 73 seconds after liftoff.
The cause was a failed booster engine, NASA said.
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 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.
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, US President Barack 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.
Its retirement left the United States with no vehicle for human space travel.
In the meantime, the world's astronauts hitch rides to the International Space Station aboard Russia's Soyuz capsules, while private companies Boeing and SpaceX ready their own spaceships for use in 2017 and beyond and NASA focuses on building its Orion deep space capsule.
