Includes the early Mercury and Gemini programs, the Apollo missions to the Moon, the Space Shuttle years and finally the International Space Station. Features over an hour of historic video footage plus 69 high-resolution photographs from the Apollo and Space Shuttle programs. All images and original footage courtesy NASA.

Videos featured:
* Project Mercury – 7 min – classic cold war relic from 1962 about the first "free men" in space.
* Gemini Program – 8 min – looks at these two-crewed missions from the mid-1960s – featuring the first rendezvous in space, spacewalks and first long duration missions.
* Apollo Program – 25 min – looks at Apollo 8 (first mission to the Moon) Apollo 11 (first landing) plus Apollos 15 and 17. Also features 36 images of the Moon and astronaut activity on the surface.
* Skylab Space Station – 5 min – NASA's first space station – looks at experiments performed and acrobatic displays.
* Space Shuttle – 11 min – features funny moments from the 30 year Shuttle program – working and playing in the weightlessness of space. Plus 33 images of Shuttle launch, in space and Earth views.
* International Space Station – 14 min – looks at the history of the Station and features a tour of the current station set up.

Moon Phase Photo Maps

Not just a Moon Map! Rather a series of actual photos of the phases of the Moon with prominent features marked and named. This makes it easy to identify features on the Moon as you are seeing them as they really are, not as an idealized representation on a map. Each Map gives priority to features on the terminator (the line between day and night on the Moon), as the low sun angle makes them stand out more. As craters recede from the terminator they become less prominent and are generally not indicated.

Opening screen shows the current Moon - navigate to other phases by swiping to each side then tap to reveal the detailed map of each phase. Layers can be added or removed depending on your requirements:
* For beginning observers using binoculars, just the names of seas can be revealed in Latin or English.
* For telescope users, the names of craters and other major features can be revealed.
* For advanced telescope users, an extra layer reveals smaller details such as Faults (F), Rilles (R) and Valleys (V).

Overall Features:
* 30 images of the Moon, 18 of the waxing moon, the Full Moon and then 11 of the waning Moon (there are less of these as they generally occur in the morning hours and are less often observed).
* Images can be shown North up or South up depending on telescope settings and location.
* Maps can be shown mirror reversed if required for your telescope orientation.
* Search for major feature names of waxing and waning Moon.

Star Charts by Wil Tirion

These are serious Star Charts! Not a planetarium-type app suitable for beginners, but rather a very detailed series of charts of the night sky for observers using binoculars or a telescope. Prepared by famous celestial cartographer Wil Tirion, they present the entire sky in the form of 18 charts, 16 covering the equatorial region of the sky (8 each side of the celestial equator) and one for each of the Polar Regions.

Features include:
* Stars down to sixth magnitude; double and variable stars included.
* All Messier objects, plus many NGC and IC catalogue objects.
* Auto detection of your location and presentation of the chart containing the sky directly overhead.
* Choice of positive charts (white on black, recommended to preserve night vision) or negative (black on white – easier to read and better for daytime use.)
* Charts can shown north up or south up to match your location.
* Search charts by constellation or major star name.

Basic default maps show constellation names, constellation lines and major star names only.
Extra layers can be added to reveal:
* Constellations boundaries for all 88 constellations.
* Grid lines and co-ordinates for every hour of Right Ascension and 10? of Declination.
* Star numbers and deep sky object names.
