Lunar Gemini 1.0

File Description:
An alternate-history "historical" add-on. Instead of, or as a backup to, Apollo, Gemini is further developed to help win the race to the moon. In this add-on, a Centaur rocket stage is outfitted with an Agena-style docking collar and launched into orbit. You will launch into orbit in your stock Gemini (not included), rendezvous and dock, and command the Centaur to send you on a free-return trajectory. Your ride into space history awaits. (Requires Gemini-Titan 4.11 or later. Earth_1962 add-on also highly recommended for maximum enjoyment).

New Skylab 2, 3 And 4 Mission

File Description:
Skylab 2 25 May 1973 13:00 GMT. Duration: 28.03 days. Call Sign: Skylab. Backup Crew: McCandless, Musgrave, Schweickart. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-206. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload : Apollo CSM 116. Mass: 19,979 kg. Location of Spacecraft: Naval Aviation Museum, Pensacola, FL. Perigee: 427 km. Apogee: 439 km. Inclination: 50.0 deg. Period: 93.2 min. Epic repair mission which brought Skylab into working order. Included such great moments as Conrad being flung through space by the whiplash after heaving on the solar wing just as the debris constraining it gave way; deployment of a lightweight solar shield, developed in Houston in one week, which brought the temperatures down to tolerable levels. With this flight US again took manned spaceflight duration record. When the meteoroid shield ripped loose, it disturbed the mounting of workshop solar array "wing" two and caused it to partially deploy. The exhaust plume of the second stage retro-rockets impacted the partially deployed solar array and literally blew it into space. Also, a strap of debris from the meteoroid shield overlapped solar array "wing" number one such that when the programmed deployment signal occurred, wing number one was held in a slightly opened position where it was able to generate virtually no power. In the meantime, the space station had achieved a near-circular orbit at the desired altitude of 435 kilometers (270 miles). All other major functions including payload shroud jettison, deployment of the Apollo Telescope Mount (Skylab's solar observatory) and its solar arrays, and pressurization of the space station occurred as planned. Scientists, engineers, astronauts, and management personnel at the NASA Marshall Space Flight Center and elsewhere worked throughout the first ten-day period of Skylab's flight to devise the means for its rescue. Simultaneously, Skylab--seriously overheating--was maneuvered through varying nose-up attitudes that would best maintain an acceptable "holding" condition. Because of the loss of the meteoroid shield, however, this positioning caused workshop temperatures to rise to 52 degrees Celsius (126 degrees F). During that ten-day period and for some time thereafter, the space station operated on less than half of its designed electrical system, in the partially nose-up attitudes, was generating power at reduced efficiency. The optimum condition that maintained the most favorable balance between Skylab temperatures and its power generation capability occurred at approximately 50 degrees nose-up. The crew rendezvoused with Skylab on the fifth orbit. After making substantial repairs, including deployment of a parasol sunshade which cooled the inside temperatures to 23.8 degrees C (75 degrees F), by June 4 the workshop was in full operation. In orbit the crew conducted solar astronomy and Earth resources experiments, medical studies, and five student experiments; 404 orbits and 392 experiment hours were completed; three EVAs totalled six hours, 20 minutes. Skylab 3 28 July 1973 11:10 GMT. Duration: 59.46 days. Call Sign: Skylab. Backup Crew: Brand, Lenoir, Lind. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-207. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload: Apollo CSM 117. Mass: 20,121 kg. Location of Spacecraft: NASA Lewis Research Center, Cleveland, OH. Perigee: 422 km. Apogee: 442 km. Inclination: 50.0 deg. Period: 93.2 min. Continued maintenance of the Skylab space station and extensive scientific and medical experiments. Installed twinpole solar shield on EVA; performed major inflight maintenance; doubled record for length of time in space. Completed 858 Earth orbits and 1,081 hours of solar and Earth experiments; three EVAs totalled 13 hours, 43 minutes. Skylab4 16 November 1973 14:01 GMT. Duration: 84.05 days. Call Sign: Skylab. Backup Crew: Brand, Lenoir, Lind. Nation: USA. Agency: NASA. Launch Site: Cape Canaveral . Launch Complex: LC39B. Launch Vehicle: Saturn IB . LV Configuration: Saturn IB s/n SA-208. Program: Skylab. Class: Manned. Type: Lunar spacecraft. Spacecraft: Apollo CSM. Payload: Apollo CSM 118. Mass: 20,847 kg. Location of Spacecraft: National Air and Space Museum (Smithsonian Institution), Washington, DC. Perigee: 422 km. Apogee: 437 km. Inclination: 50.0 deg. Period: 93.1 min. Included observation and photography of Comet Kohoutek among numerous experiments. Completed 1,214 Earth orbits and four EVAs totalling 22 hours, 13 minutes. Increased manned space flight time record by 50%. Rebellion by crew against NASA Ground Control overtasking led to none of the crew ever flying again.

New EMU and LRV meshes for NASSP v2.2 (BETA2)

File Description:
This add-on is simply a slight modification to an already superb add-on done by Spacebar Joe (NASSP) and I created it to enhance the ambience and experience of lunar landings in Orbiter. Although the Orbiter simulation engine is still quite limited when it comes to modelling character or land vehicle movement, the NASSP package offers a nice way for you to do this. However, I was not satisfied with the 3D-models that came with the add-on, so I decided to create my own detailed 3D-models for the lunar astronaut (EMU) and the lunar rover (LRV). The new models are named sat5AstroS.msh (745 kb), and LRV.msh (1,617 kb), both of which will OVERWRITE the older NASSP astronaut and LRV models. Please back up these two files (in your meshes folder) before installing this add-on. The LRV was created based on 3-views (plans) photos and drawings that I got from the Apollo Lunar Surface Journals (ALSJ) Website. The EMU model was created mostly from videos and pictures of Apollo spacesuits. It features a semitransparent faceplate (visor up) and you can actually see the astronaut’s head inside the helmet! ;) NOTE that this is still a BETA (work in progress) and the models will be updated periodically. WARNING: Due to the fact that these models are quite polygon-heavy, some slower computers with low-end graphics cards will run very slow if my models are active. There might also be cases when ORBITER will crash due to the complexity of the models. More info can be read in the PDF file that comes with the package.

Minuteman II Missile

File Description:
The Minuteman was Americas Third Operational ICBM System. During the Cuban Missile Crisis it was America's "Ace In The Hole". It has been operational at U.S. bases since 1962 reaching a peak of 1,000 missiles. The Minuteman II program was economically crucial to the development of integrated circuits. It was the first mass-produced system to use a computer constructed from integrated circuits, and used most of the production of such circuits from 1962 through 1967. The other major customer of these circuits was the Apollo Guidance Computer, which had similar weight and ruggedness constraints. The Orbiter version keeps up with the historical aspect of this horrible weapon. This add-on is created for historical purposes only, and we do not condone using Orbiter to simulate nuclear war. No active Minuteman II missiles currently exist today. The only way to see one now is at a museum or on display at various Air Force bases world wide. This add-on simulates the flight plan and package delivery of a real Minuteman II missile. The warhead included in this add-on is from the Trinity package created by Dave Rowbothham. The warhead activates at about 4 minutes to impact. It arms at 2000 feet and detonation occurs at 1800 feet.
