The Mars Globe HD app is an enjoyable astronomy tool that you can use to learn about the planet Mars and the many space missions that have landed on its surface. The application has been recently updated to run at full resolution on the new iPad.

I’m a volunteer telescope operator at the Flandrau Science Center in Tucson, Arizona. I, along with about a dozen other volunteer telescope operators, take turns several times a month showing the night sky to the public through the Center’s sixteen inch Cassegrain reflector telescope.

The planet Mars has recently passed through opposition to the Sun, which means it is closer to Earth at this time as we orbit the Sun. Rising in the eastern evening sky it appears as a bright, rusty colored star-like object. Observing Mars through the Center’s telescope we can only see some of the subtle coloration details on the surface of this small planet that is roughly half the size of Earth and over seventy-seven million miles away. These subtle variations in color are associated with surface features such as craters, mountains, valleys, and surface materials.

This year is a special year for Mars exploration because we have the Mars Science Laboratory, a rover named Curiosity, en route to the planet and scheduled to land in early August. We can use the Mars Globe HD app to show what those surface details are and even check out where Curiosity is targeted to land.
