HOUSTON (KTRK) --NASA will observe a solemn anniversary today.
The Challenger accident happened 30 years ago today. NASA is set to honor the victims of that accident across multiple states today.
It is hard to believe it has been three decades since America witnesses that disaster after liftoff in a moment that should have been historic for a different reason.

As many know, 73 seconds into the launch, the space shuttle exploded, killing all seven astronauts on board.
NASA's day of remembrance events are set for 9am, and is a time to pay tribute to the lives lost, including the three astronauts who perished in the Apollo One mission in 1976.
The seven astronauts who died when Columbia broke up as it reentered the atmosphere over Texas and Louisiana will also be remembered.
At Johnson Space Center, employees will place flowers at the base of three trees that were planted in memory of the victims.
