Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
STS-51-L was the 25th mission of the United States Space Shuttle program, the program to carry out routine transportation for Earth-to-orbit crew and cargo; as well as the final flight of Space Shuttle Challenger. 
Planned as the first Teacher in Space Project in addition to observing Halley's Comet for six days, the mission never flew past orbit; a structural failure during its ascent phase 73 seconds after launch from Kennedy Space Center Launch Complex 39 on January 28, 1986, killed all seven crew members—Commander Dick Scobee, Pilot Michael J. Smith, Mission Specialists Ellison S. Onizuka, Judith A. Resnik and Ronald E. McNair, and Payload Specialists Gregory Jarvis and Christa McAuliffe—and destroyed the orbiter.
Immediately after the disaster, NASA convened the Rogers Commission to determine the cause of the explosion. The failure of an O-ring seal on the starboard Solid Rocket Booster (SRB) was determined to have caused the shuttle to break-up in flight. Space Shuttle flights were suspended for 32 months while the hazards with the shuttle were addressed. The Space Shuttle program resumed with STS-26, launched two years after the accident.
