Can a planet have three or more different sky colors?

Can a planet have three or more different sky colors?

Yes. Planets get their sky color from the scattering of shorter wavelength blue light in comparison to the longer wavelengths of other visible colors. Therefore, depending on the atmosphere thickness, planets should have blue skies. So why did we see a red sky on Mars through the eyes of the Mars Pathfinder? When the probe took pictures that contributed to this visualization of the red planet, Mars was currently experiencing iron-rich dust storms. Therefore, the sky can in fact change color with different atmospheric conditions such as weather and--in the case of Earth--pollution.

Successful Launch for Atlantis; News Conference Coming Up

Space shuttle Atlantis is officially in orbit, kicking off its STS-132 mission and the pursuit of its target, the International Space Station. Atlantis lifted off from NASA's Kennedy Space Center right on time at 2:20 p.m. EDT, rising into a picture-perfect Florida sky and capping a relatively problem-free countdown.

NASA Television will air the STS-132 postlaunch news conference at 3:30 p.m. EDT with Bill Gerstenmaier, associate administrator for Space Operations, Alexey Krasnov, chief of Piloted Programs Directorate, Roscosmos, Mike Moses, chair, prelaunch Mission Management Team, and Mike Leinbach, shuttle launch director.


STS-132 Overview

Space shuttle Atlantis is embarking on its final planned mission. During the 12-day flight, Atlantis and six astronauts will fly to the International Space Station, leaving behind a Russian Mini Research Module, a set of batteries for the station's truss and dish antenna, along with other replacement parts.

NASA astronaut Ken Ham will command an all-veteran flight crew: Pilot Tony Antonelli, and Mission Specialists Michael Good, Garrett Reisman, Piers Sellers and Steve Bowen.

After the final STS-132 Flight Readiness Review, John Shannon, Space Shuttle Program manager, pointed out that Atlantis' last planned mission will be an exciting one.

"Twelve days, three [spacewalks], tons of robotics... We're putting on spares that make us feel good about the long-term sustainability of the ISS, replacing batteries that have been up there for a while, and docking a Russian-built ISS module," Shannon said. "This flight has a little bit of everything, and it's been a great preparation for the team."
