“The space shuttle Challenger is destroyed, just a little more than one minute after lift-off. All seven astronauts on board are killed.” (ABC)

REGAN: “We will never forget them, nor the last time we saw them this morning as they prepared for their journey and waved goodbye -- and slipped the surly bonds of Earth to touch the face of God.” (NBC)

It's been 25 years since the Challenger explosion -- some of you might remember where you were, whether you were watching it live on TV or sitting in a classroom listening to it on the radio. But after a quarter of a century, the Challenger crew is being honored as their surviving family members keep their legacy alive.

“The families who lost loved ones during the Challenger disaster created a legacy that’s educating thousands of children each year. It’s called -- The Challenger Learning Center.” (WRTV)

JUNE SCOBEE RODGERS: “To see the team effort representing the entire crew … I think Christa would be pleased. I think she would be very proud ... We didn’t want the Challenger to be the end of the chapter in space exploration. We saw it as a transition chapter.” (NBC)

Several memorial services were held in honor of not only the Challenger victims, but all 24 astronauts who have died on NASA missions. As CNN reports, it’s an emotional week for the space administration.

“It’s a bad time of the year for NASA. Yesterday was the anniversary of the Apollo 1 fire -- Grissom, White and Chaffee -- and on February 1st is the anniversary of the Columbia accident, so a tough time of the year for the NASA family.”

A former flight director who was working at NASA during the Challenger explosion tells Space.com, he and his colleagues remember the shuttle disasters with heavy hearts.

“I think there isn't a single one of us that was in the human spaceflight program when any of these events happened that doesn't wish that we could go back and change something, make it different, do something different."

Amid the somber memories, New Scientist says NASA has learned from the Challenger and the Columbia disasters and is now developing new technology in attempt to make space travel safer.

“Even those new to the market like SpaceX are testing uncrewed launches first, which puts them at a safety advantage compared with the shuttle's first flights.”

The Christian Science Monitor points out several positive ways the Challenger improved space travel, such as sending the first women into space.
