The northeastern United States is experiencing record-breaking cold weather, with temperatures 20 to 30 degrees below average, according to the National Weather Service. Those are temperatures so frigid that parts of Mars—a cold, desert planet—are actually warmer than certain spots in the U.S. But how does Mars’ climate compare to that of our home planet?
If you’re going to Mars, which do you bring: water or a shovel? The question may sound a little tongue-in-cheek, but it actually goes right to the heart of a critical need for future human exploration of Mars – accessible water. Learn how the MARSIS instrument is helping answer this question.
When John Grant was only 16, the Viking landers were sent to Mars. Today, Grant helps lead the operation groups controlling two Mars rovers, Opportunity and Curiosity, as a geologist at the National Air and Space Museum’s Center for Earth and Planetary Studies. Recent data collected by Curiosity and published in Science describes an ancient lake environment located at Gale Crater—an environment Grant, a coauthor of the article, believes holds further clues to whether there was ever life on the Red Planet.
It's 5 o'clock somewhere on Mars!
No human has ever set foot on Mars, but scientists have been working there for years. A day on the red planet is about 40 minutes longer than here on Earth, which wreaks havoc on your workweek.
On this day in 2007, the Mars Phoenix lander was launched from a Delta II at Cape Canaveral Air Force Station, Florida. Phoenix flew to a site in the far northern plains of Mars where it analyzed components of the surface, subsurface, and atmosphere.
As the National Air and Space Museum’s annual Mars Day! celebration approaches, we look to a recent research trip taken by a Smithsonian Summer Intern to investigate the similarities between some of Earth’s most amazing dunes and those found on the ruddy surface of Mars.
The recent announcement by NASA that there is evidence of salty, liquid water seeping out of the ground on Mars is both exciting and scientifically puzzling at the same time. As a member of the science team for the High Resolution Imaging Science Experiment (HiRISE) camera on board the Mars Reconnaissance Orbiter (MRO), I’ve been hearing about these possible seeps, or Recurring Slope Lineae (RSL), for several years now.
Director of the Jet Propulsion Laboratory (JPL) from 1976 to 1982, Bruce Murray was a geologist whose vision was never earthbound. He earned his PhD from MIT and served two years in the U.S. Air Force before joining the California Institute of Technology (Caltech) in 1960. Caltech manages JPL for NASA, and soon Murray was working on JPL’s Mariner missions to Mars. During his tenure as director of JPL, the Viking spacecraft landed on Mars and the Voyagers began exploring the outer solar system. He also oversaw Earth orbital missions, including Seasat, the Solar Mesosphere Explorer, and Shuttle Imaging Radar-A.
The Viking program represents a major effort by the United States to explore Mars, with the particular goal of performing experiments on Martian soil to look for possible evidence of life. Four individual spacecraft were sent to Mars as part of the Viking project, two orbiters and two landers, launched as identical orbiter/lander pairs.
