  • Marsquake! NASA's InSight Lander Feels Its 1st Red Planet Tremor

    Scientists just felt the Red Planet move under their feet — robotically from millions of miles away, on the stark surface of Mars. On April 6, NASA's InSight lander sensed its first confirmed marsquake, a phenomenon scientists suspected, but couldn't confirm, occurred on the neighboring planet. Measuring the Martian equivalent of earthquakes, seismic waves traveling through the interior of the planet, was among the lander's key science goals. "We've been waiting months for our first marsquake," Philippe Lognonné, the principal investigator for the seismometer instrument, said in a statement released by the French space agency, which runs the instrument with...
  • Mars shocker: Liquid water lake found on the Red Planet

    Scientists have uncovered a "a stable body of liquid water" on Mars, in what some are calling a "game changer" in the search for alien life. What is believed to be liquid water is sitting below Mars' southern polar ice cap and is described as a "well-defined, 20-kilometer-wide zone." 20 kilometers is roughly 12.5 miles. The findings, which are published in the journal Science, were made possibly by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS), an instrument that resides on the Mars Express spacecraft. MARSIS surveyed Mars' Planum Australe region between May 2012 and December 2015 and utilized...

    If Martians exist, they'll be closer to Earth on Memorial Day than they have been in 11 years. This Monday, around 5:34 p.m. EDT, when many Americans may be enjoying a holiday barbecue, the Red Planet will be the closest it has been to Earth in more than a decade, coming within 46.8 million miles, according to NASA. The relatively close encounter with Earth comes a week after the Martian opposition, when Mars and the sun lined up on exact opposite sides of the Earth.

    space.com ^ | Leonard David,
    The ideal Red Planet crewed site should be of high scientific value — allowing pioneers to search for signs of Mars life and investigate other intriguing questions — and also possess enough resources to help sustain expeditionary crews, scientists and engineers said. They came to these and other conclusions at the First Landing Site/Exploration Zone Workshop for Human Missions to the Surface of Mars, which was held here Oct. 27 though Oct. 30 at the Lunar and Planetary Institute. ... Nearly 50 locations on Mars were proposed as future locales for human landings. Those sites were all within 50 degrees...
  • NASA photo captures strange bright light coming out of Mars

    A NASA camera on Mars has captured what appears to be artificial light emanating outward from the planet's surface. The photo, beamed millions of miles from Mars to the Jet Propulsion Laboratory in Pasadena, Calif., was taken last week, apparently by one of two NASA rovers on the red planet.

    Mars, Like Earth, Has Cyclical Ice Ages, Study Says Brian Handwerk for National Geographic News September 14, 2007 Mars has gone through 40 ice ages during the past five million years that regularly send the planet's permanent ice sheets cascading toward the equator, then melting backward, a new theory suggests. The climate changes are likely driven by cyclical fluctuations in the planet's orbit that alter the amount of sunlight that falls on the planet's surface, says astronomer Norbert Schörghofer of the University of Hawaii at Manoa. Understanding the sun's exact role in the Martian ice ages could help solve longstanding...

    Nasa release on the topography of the south polar region of Mars Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars.The candidate caves are on the flanks of the Arsia Mons volcano and are of sufficient depth their floors mostly cannot be seen through the opening. Details were presented here at the Lunar and Planetary Science Conference in Houston, Texas. Temperature data from Mars Odyssey's Themis instrument support the idea. The authors say that the possible discovery of caves on the Red Planet is significant. The caves...

    PASADENA, Calif. - The most powerful spacecraft ever sent to Mars has settled into a nearly circular orbit, a move that allows scientists to begin studying the planet in unprecedented detail, NASA said Tuesday. The Mars Reconnaissance Orbiter fired its thrusters for 12 minutes Monday to adjust to its final position six months after it arrived at the planet. Its altitude ranges between 155 to 196 miles above the surface. "Getting to this point is a great achievement," said Dan Johnston, deputy mission manager at the space agency's Jet Propulsion Laboratory, which manages the $720 million mission. Over the next...

    LOS ANGELES - A NASA spacecraft bound for Mars is nearing the end of its seven-month journey but still faces a white-knuckle arrival at a planet known for swallowing scientific probes, mission managers said Friday. The Mars Reconnaissance Orbiter, or MRO, is on course to enter orbit around the Red Planet on March 10. If successful, it will spend the next two years photographing the surface and scouting for future landing sites. The spacecraft is performing so well that engineers have canceled two final maneuvers to adjust its course in the last leg of the trip, said James Graf, project...

    Red Planet By: Lowell Ponte FrontPageMagazine.com | May 29, 2002 THE FOOTPRINTS ON MARS HAVE FASCINATED scientists. Could such a thing long ago really have moved across the surface of the Red Planet? Apparently it could and is still there, lurking only three feet beneath the thin layer of iron oxide rust whose blood-red color led ancient Romans to name this heavenly body for their god of war, Mars. This Thursday the journal Science will publish three studies of data from the Mars Odyssey spacecraft. It has detected vast amounts of hydrogen. The most likely conclusion from this, according to...

Ice reservoirs found on Mars By Dr David Whitehouse BBC News Online science editor Water-ice has been found in vast quantities just below the surface across great swathes of the planet Mars. The finding by the American space agency (Nasa) is undoubtedly one of the most important made about the Red Planet. It solves one of its deepest mysteries, points the way for manned exploration and reignites the question of whether life may exist on the planet. Insiders suggest that, partly as a result of this finding, Nasa may now commit...
