Bob Ebeling, a Challenger engineer who predicted the space shuttle would explode, never truly forgave himself for the deaths of the seven crew. After three decades of guilt over the disaster, he passed away on Monday aged 89 in Brigham City, Utah, following a long illness. The former engineer for NASA contractor Morton Thiokol was part of a team of four that tried to warn the space agency against the launch, saying the temperatures in Cape Canaveral were too cold for the booster rockets to seal properly.

Images from Jan. 28, 1986, are seared into the memories of former schoolchildren, teachers, parents, and pretty much any American now older than 30 - the Challenger space shuttle, meant to carry school teacher Christa McAuliffe into orbit, reduced to a snaky tunnel of smoke in the sky near Cape Canaveral. In the years that followed, a lot would come out about a disaster watched in countless classrooms across the nation: about faulty O-rings, about dangerously cold temperatures, and about how five crewmen, an engineer and a New Hampshire teacher meant to represent NASA in its finest hour became the...

January 28th marks 30 years since the Challenger Disaster. Seems so long ago, yet it is one of those days people never forget. School was out that day, probably because of bad weather, and I remember watching on television the news showing the explosion over and over. I will never forget. We didn’t give up on spaceflight that day, but I wish more would have seen the real promise of the Final Frontier. Instead, many in government still see it as another “get-elected-for-a-few-years” opportunity. The vision of government sees only through the next election cycle, not seven generations hence. There...

CAPE CANAVERAL, Fla. (AP) — NASA is offering up wreckage from the Challenger and Columbia for public view after hiding it from the world for decades.

Beyoncé has been labeled "insensitive" by some current and former NASA astronauts and their families for sampling audio from the space shuttle Challenger disaster for a love song off her newly released album. Challenger exploded 73 seconds after liftoff from the Kennedy Space Center Jan. 28, 1986. All seven crewmembers aboard were killed. "Flight controllers here looking very carefully at the situation. Obviously a major malfunction," now-retired NASA public affairs officer Steve Nesbitt said as the nation watched wreckage fall toward the ocean on live television. Twenty-seven years later, Nesbitt's voice is heard at the beginning of the video for...

The night before the 1986 explosion, Boisjoly and four others argued that joints in the shuttle's boosters couldn't withstand a cold-weather launch.

Where were you on January 28th, 1986? Were you in a classroom watching the first teacher go into space? Do you remember how you felt when you saw the Challenger explode soon after it left the earth? CNN reports that about 17% of Americans were watching when the disaster occurred. One hour later, 85% had heard the news. It is estimated that 48% of 9-13 year-olds were watching. Teacher Christa Macauliffe was supposed to be the first teacher in space, but she never made it. She died in the explosion along with the six astronauts accompanying her. Most of today's...

This day in 1986, the day the Challenger exploded, was one of this Nation's worst days on record. Andrea Shea-King was working the launch as a public affairs announcer. She introduced the crew as they headed for the launch pad. From Andrea's post: "As they approached the tv cameras, I keyed the mic. Here's my voice describing the astronauts' walkout."
