Free moon exploration software for mac

The Moon Phase widget displays the current lunar phase as visible from the Earth. North is at the top.
Enhancements:
- switched to a julian date method and made adjustments for accuracy.

Explore! is a desert exploration game in the spirit of the classic adventure games of the olden days. It is a game by Durandal Brytting, of minor fame as connoisseur of old Mac games.

Like most of the games, it strives to return to the good old days when games lasted. Also, I’m pretty sure that it’s an educational game for your kids. If nothing else they might learn some long words and what a desert rose is.

Calculates and displays the Date, time and Lunar Latitude per month for a given year (includes offsets from Prime Meridian and either UT or local time).
The routines are written in BASIC, are not object oriented and make some assumptions about both software and hardware platforms.
Lunar orbital accuracy is a non-trivial task. The equations for New Moon Dates are derived from the equations used in the book: "Astronomy with Your Personal Computer" by Peter Duffett-Smith.The accuracy claimed in the book is accurate to within two minutes (page 172 of the second edition).The information displayed is the date of the New Moon and the New Moons latitude.You will have to decide if this is enough accuracy for your needs.
Enhancements:
- Added Daylight Savings Time and an indicator to show when it has affected the date shown.

KFDecorator can produce, at runtime, a wrapper object that modifies the behavior of an underlying base object. Methods like -[KFDecorator setBlock:forSelector:] allow the user to provide FScript blocks to execute in response to messages. Messages without a specified FScript block are passed on to the base object. This can also be used to build an object up from scratch as an assemblage of FScript blocks.

This is extremely useful during the exploration and debugging stages of development. By building or modifying objects dynamically, its possible to avoid the compilation stage until you have a decent idea of what code youd like to implement.

ConverTable Planets is designed to answer that age-old question, "if a widget weighs 34 stones on Earth, just how many troy ounces would that widget weigh on Mars?" In doing so, ConverTable Planets could be used to teach about unit conversions and gravity.
Main features:
- Find out how much you would weigh on the Moon, Mars, and 24 other places in the solar system.
- View the planets and included moons in their true relative sizes!
- Learn how many Venusian (or Martian, Saturnian, etc.) years old you are!
- Planets included (the whole solar system, of course!): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
- Moons included: Earths Moon, Io, Europa, Ganymede, Callisto, Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Iapetus, Miranda, Umbriel, Titania, Oberon, Triton, and Charon.
- Several mass and weight units are available: kilograms, pounds, grams, milligrams, stones, troy ounces, slugs, newtons, metric tons, and metric carats.
- Brief discussion of the common "mass or weight" language confusion, and what exactly is a "year."
- French localized version available.
Enhancements:
- added "Year Conversions" function to compare year (orbital period) lengths on the planets.
- improved some planet and moon descriptions
- added planet and moon datasets which appear in the "Year Conversions" section
- changed to a primarily single-window interface.
