The updated main sign-up and overview/intro page:

New promo video for NSF and L2, kindly created by
www.stormsurgemedia.com - run by Richard, who is an active member on site.
http://www.youtube.com/v/BJL2MhsCqLk&rel=1L2 is now seven main sections:
1) Mission Special Section:
Covers specific mission content, from PRCB baseline presentations, daily NTD/KSC integration level processing coverage, FRR presentation coverage, MMT pre-launch and Flight Day coverage, through to post flight IFA, etc.
2) International Space Station Section:
Operational manuals, Assembly and Robotics Presentations, SSPCB notes, 8th Floors, Russian documentation, Tour videos etc.
3) Russian Space Flight:
Documentation, Photos, Updates and Video on the Russian/Soviet Space Program, from MIR to Buran (four long exclusive videos in Russian), through to the ISS modules and the Russian "ESAS" presentations (55/500mb) on their next generation vehicle.
4) Space Flight L2: Shuttle and current vehicles Section:
Future flight processing and documentation, Previous mission documentation (post RTF), General documentation, Extension studies, Shuttle manuals (SCOMs etc), SSME bibles, SRB/RSRM bibles (master presentations). A lot of the tag cloud content lives there.
5) Constellation To Future Plan Transition Section:
Large amount of Ares and Orion presentations from the beginning to present. COTS/CRS (NASA side), Commercial (EELV). Very much filling up with SD HLV and HLV presentations. Future KSC hardware such as the new ML master sections. Lots more, anything on any future videos is located in there. Includes a good number of videos.
6) Historical Section: From the first days of Cape Canaveral, through to Saturn/Apollo and the early days of the shuttle program. Huge amount of images (400Gb at last estimate). Full Hi Res images from nearly every mission. Orbiter construction in California. Apollo, Gemini and videos. MER reports for every mission. Old Skool vehicles from the days of the Atlantic Missile Range. Too many elements to mention.
7) Video Section:
Home of several full re-entry videos taken from a hand-held camcorder on the flight deck. Every STA training video from all runways from all three primary landing site. MOD flight controller training class videos (really cool). VAB/PAD/OPF tour video. Videos from engineers such as lighting the flare stack. Personal tours of Dryden and inside the SCAs. Four very long and unreleased Buran videos. SRB re-entry video from recovery ship etc, Covers lots of vehicles over lots of years.
Some L2 video samples:
http://forum.nasaspaceflight.com/index.php?topic=9944.msg189521#msg189521Everything on L2 is not available on ANY other site. On the rare occasions we do break news/images etc, and a few weeks later NASA decide to release them publicly, we move it off L2.
Each section has a request (Shopping List) form, which our sources (we have a lot of those) use to send us further L2 information as per request. You can also post further questions on the information in L2 due to the forum format. One of the major strengths of L2 is the large amount of actual space industry on L2 who are happy to answer questions/elaborate on what is contained in there, especially during missions.
Six main sections are splintered off into over a 100 specific clickable topic areas, accessed via the L2 tag cloud, allowing for a menu of content from mission specific to vehicle specific and even hardware specific. See second post for a walkthrough.
The entire database is well over 4,500gbs in size and over four years of building – containing information that ranges from the present, to the future, and as far back as the start of the space program. It's updated literally daily with new content.
Your subscription warrants your use of our servers for unlimited downloading, in turn allowing the revenue gained from L2 subscriptions to be used to improve the site, keep the majority of the site and news as free access, and playing a part in helping NASASpaceflight.com’s present and future stability.
All L2 revenue is used solely on paying the large costs of hosting such a massive site. Nobody takes a salary from NSF, we all have other 'day jobs'. We're not asking for donations in return for a thank you, we're thanking you by giving you access to easily best subscription area related to space, and arguably on any subject given the level and range of content.
Nothing on L2 is ITAR, Export Control or Proprietary.
