CPT-USN Eugene A. ‘Gene’ Cernan (14 March 1934 - 16 Jan 2017)

Gemini 9, Apollo 10, and Apollo 17 astronaut, the last man to set foot on the surface of the moon, passed away today at the age of 82. Cernan, a rough, tough Naval Aviator, A-4 jock, became part of NASA Group 3 in 1963. Gemini 9 in June 1966, proved a harrowing experience for Gene, it was one that taught us many invaluable lessons about EVA in space, a crucial step to the moon. Apollo 10 in May 1969, was to be the final test of the LEM ascent and descent stages and of it’s guidance systems from lunar orbit, a vital test flight that paved the way to Apollo 11′s historic first landing later that year. Apollo 17, the last of the historic 6 Apollo Lunar missions, in December 1972, Gene was in role as Commander of the flight, piloting the LEM along side Harrison Schmitt, landing in the mountainous region of the Taurus-Littrow valley. Gene became the last human of only 12 to set foot on the Moon.

Does Mars have rings? Not right now, but maybe one day

As children, we learned about our solar system’s planets by certain characteristics – Jupiter is the largest, Saturn has rings, Mercury is closest to the sun. Mars is red, but it’s possible that one of our closest neighbors also had rings at one point and may have them again someday.

That’s the theory put forth by Purdue University scientists, whose findings were published in the journal Nature Geoscience. David Minton, assistant professor of Earth, atmospheric and planetary sciences, and Andrew Hesselbrock, a doctoral student in physics and astronomy, developed a model that suggests that debris that was pushed into space from an asteroid or other body slamming into Mars around 4.3 billion years ago and alternates between becoming a planetary ring and clumping up to form a moon.

A theory exists that Mars’ large North Polar Basin or Borealis Basin, which covers about 40 percent of the planet in its northern hemisphere, was created by that impact, sending debris into space.
