Explore a 3D globe of Mars

Mars Atlas is an astronomy application that lets you use pinch and finger gestures to manipulate a 3D globe of Mars. As you zoom in more labels appear as finer detail comes into view. You can double tap on the labels to get more information about a particular feature.

Mars Atlas displays the approximate phase, axial tilt and central meridian of Mars from your chosen location and time, and renders these on the globe. You can switch to a 'Globe' mode that allows you to spin Mars around to see the whole globe. The feature database is searchable and can move the globe to a searched feature. The phase can be switched off to show the whole globe more clearly.

Date, time and location can be changed. There is also a realtime mode that will update to the current time.

The Mars globe can be shown with north or south at the top or inverted to suit different telescope views.

Over 1600 named features are included as well as 6 spacecraft that returned data from the surface of Mars.

You can swipe left and right on the phase view to go backwards and forwards a day.

Moon, Mercury, Venus, Jupiter and Saturn atlases are also available on the App Store!

Also there is Planisphere, a star charting app, available on the App Store!

Could be much better

This program has only one failing. Resolution. Not enough of it.

The surface detail takes VERY little zooming in before it starts becoming a blocky mess. Otherwise a beautiful and very well implemented program with loads of features, but on the iPad it's simply not detailed enough by half. As a nitpick, would it be possible to have true 3D mapping? Olympus Mons is just a flat feature - would be great if it stuck out in 3D, though I know that might require a serious amount of processing.

Three stars until the map gets a fee more pixels.

Mars Atlas

As an astro geek I was keen to get this app and expected a good product cos of the biggish price tag. It's ok and does what it says on the tin - just don't expect to see a huge lot of surface detail on the planet - this isn't a Google Earth type app! With all the photo data from Mars probes that NASA has I maybe expected a bit more sharpness and detail - but I guess that would be costly to do at an iPhone app price?



Fantastic program! As moon atlas it's amazing. My only gripes would be PLEASE can you make the pan view work from where ever you are when I'm globe mode, rather than panning back to a set point, it drives me mad!! Otherwise it's ace, and a little higher red would be a dream.

Great work.
