NASA space missions have always been a source of fascination amongst the general public and films like Apollo 13 have tried to encapsulate the experience of space travel. The famous words “Houston, we've had a problem,” uttered by Lovell on the second day of what was to be the USA's third lunar landing mission, remains just as famous at the aborted mission itself. Now, thanks to British programmer Andrew Godwin, it is possible to view the actual NASA transcripts online. Spacelog.org has published the radio transcripts of the earliest manned NASA missions to space. Currently the site hosts the Apollo 13 transcripts along with Mercury-Atlas 6, John Glenn's mission aboard Friendship 7 as the first American to reach orbit.
Spacelog.com allows you read the radio transcripts between the Apollo 13 crew and NASA personnel stationed at Houston in each phase of the mission.

The Mercury 6 mission transcripts follow John Glenn as he performs three orbits of the Earth communicating with NASA personnel stationed around the world.
You can also view historical photographs taken from the missions and other documented information, including the problems that occurred and the measures taken aboard and/or from ground control. There's also a glossary to help you decipher the technical terms and acronyms used in the transcripts.
The site also allows you to search for different phases of the missions and key moments within them. Each line of the transcripts starts with a timestamp, in Ground Elapsed Time, which is the time (in days, hours, minutes and seconds) after lift off.
Soon to arrive at spacelog.com will be the Gemini 7 (half of the first orbital rendezvous), Apollo 8 (first human space flight to exit Earth's orbit) and Apollo 11 (first landing on the moon) missions and transcripts.
