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!
This version has been completely rewritten using the Swift programming language and replacing OpenGL with Metal.
Ratings and Reviews
Great for Astronomers of All Ages!
Everyone can enjoy all of these atlases as works of art as well as reliable references. They are easy to use and fill the needs of astronomers of all ages. They are well worth the modest fee. It’s an investment in program improvements, and hopefully the creation of atlases for other planets.
A very comprehensive and educational app
I'm an astrophotographer who's been capturing high resolution photos of Mars with my telescope and webcam. The Mars Atlas app has helped me enormously to identify specific features in my images such as Candor Chasma and Valles Marineris. I especially like the identification of very small features like Airy Crater which measures only 25 miles wide. Also the app provides a longitude and latitude grid with numerical values which helps in knowing exactly where one is for any selected time. One can flip the image so that North or South is up and turn the labels and long/lat grid on or off. One may choose a real time update so that the globe rotates slowly with the passage of time or one may freeze the time at any user selected day, hour, and minute. The view of Mars can be chosen as the planet would be seen from Earth or as a freely rotable globe. The phase of Mars may be turned on or off. This app was worth every penny and offers great educational value.
Again, just what I was looking for. Same great format as Moon Atlas. Beautiful to look at and use. I especially love the spacecraft locations. Well worth the price. Apps like this are what makes iPhone the best. Thanks for the terrific app!
