Global Map Mars

Astrophotographer Jean-Luc Dauvergne spent 6-nights at the Pic-du-Midi observatory in the French Pyrenees capturing the best global map of Mars yet from Earth. His team used the observatory’s 1-meter telescope and its native 17000mm focal length. The telescope was originally built to help NASA researchers prepare for the Apollo missions in the early 1960s, and to this day, it’s still one of the best in the world to study planetary surfaces in the visible part of the spectrum.

After seeing the amazing images captured by amateur astrophotographers with their backyard telescopes, he was inspired to create this global map, especially after realizing that there was enough data to create this masterpiece. In all, it took just 10-days to process the last images of Mars from Pic du Midi.

Celestron - NexStar 127SLT Computerized Telescope - Compact and Portable - Maksutov-Cassegrain Optical Design - SkyAlign Technology - Computerized Hand Control - 127mm Aperture
  • Computerized star locating telescope: The Celestron NexStar 127SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it.
  • Compact and portable: This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere.
  • Maksutov-cassegrain optical design: The NexStar 127SLT is the second-largest in the SLT family. The 127mm aperture gathers enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s cloud bands, and the Moon in brilliant detail.
  • Fast setup with skyalign: Celestron’s proprietary SkyAlign procedure has you ready to observe in minutes. Simply center any three bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects.
  • Bonus free starry night software: The NexStar 127SLT Computerized Telescope includes a free download of one of the top consumer rated astronomy software programs for an interactive sky simulation.

Spacecraft exploration of Mars over the past couple decades has greatly improved our understanding of what geologic materials, events and processes shaped its surface. The new geologic map brings this research together into a holistic context that helps to illuminate key relationships in space and time, providing information to generate and test new hypotheses,” said USGS scientist and lead author, Dr. Kenneth Tanaka.
