Free moon lander 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.

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.

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.

To The Moon is an icon set of 7 icons that represent NASAs Mercury, Gemini and Apollo capsules, as well as the moon, re-entry, a space helmet and a Lunar Module (LEM). A free desktop picture is also included.

Sunlit Moon displays the true phase of the Moon. The orthographic image is rendered from an equirectangular atlas of the Moon based on data gathered by the NASA Lunar Orbiter missions. The atlas is courtesy of the USGS Astrogeology Research Program. Each rendered image accounts for optical and physical libration. Meaning, it displays only the lunar features that are currently visible from Earth due to the effects of libration.

The green compass represents geographic direction and the gray represents selenographic direction. These are drawn to illustrate the offset of the lunar poles to that of the Earth’s poles due to libration. For examples of lunar libration, visit the Lunar Libration page. Clicking on the image of the Moon in the widget displays a selenographic grid to further illustrate the effects of libration. Also, the age and illuminated fraction is displayed.

Requirements: Mac OS X 10.4 or later
