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
=======
National Security Space Launch (NSSL) is a program of the United States Air Force (USAF) intended to assure access to space for DoD and other US government payloads.
Started in 1994 as the Evolved Expendable Launch Vehicle (EELV) launch system program, the initial program goal was to make government space launches more affordable and reliable, leading to the development of the Delta IV and Atlas V EELV families. As of 2019, these launch vehicles are the primary methods for launching U.S. military satellites, along with the Falcon 9 developed under NASA's CRS program.On 1 March 2019, the program changed its name from EELV to National Security Space Launch (NSSL) to better reflect the changing nature of launch contracting, including the retirement of STS and the inclusion of reusable vehicles. The NSSL program launches the nation's most valuable military satellites; contracts to launch lower value payloads, such as those of the Space Test Program, are awarded using different methodologies.
