The Mars Daily Editorial Team produces Mars Daily's coverage of Mars exploration and science. We report on rovers and orbiters, sample-return and human-Mars planning, and the geology, atmosphere and astrobiology of the Red Planet. Articles reflect our team's collective editorial process, source verification, drafting, technical review, and editing, rather than a single writer's work.

NASA Delays Mars Scout Mission To 2013

Washington DC (SPX) Dec 24, 2007 - NASA has decided that the next mission in the Mars Scout program, originally planned for launch in 2011, is now targeted for launch in 2013. The schedule slip is because of an organizational conflict of interest that was discovered in one of the mission proposal team's Phase A Concept Study. This was the shortest delay for the mission possible because opportunities to send spacecraft to Mars occur only once every 26 months.

International Group Plans Strategy For Mars Sample Return Mission

ESA, NASA and an international team are developing plans and seeking recommendations to launch the first Mars mission to bring soil samples back to Earth.

Opportunity Maneuvers Around Steeper Slopes In Victoria Crater

Pasadena CA (SPX) Dec 21, 2007 - Opportunity is now in the process of driving to the third band of light-colored rocks that circumvent Victoria Crater beneath the rim. Scientists had initially planned to have the rover head directly downhill to a rock target nicknamed Ronov, within the band known as Lyell.

Spirit Update: Soon To Find Winter Resting Place

Pasadena CA (SPX) Dec 20, 2007 - To make the most of waning sunlight during the approach of Martian winter, Spirit's handlers have returned to Mars time. This means their working hours coincide with the Martian day, as they did for the first three months after the rover landed on the red planet. Because a Martian day is about 40 minutes longer than an Earth day, Mars time can coincide with all hours of the day and night on Earth.

The Closest Approach Of Mars In 2007

Pasadena CA (SPX) Dec 19, 2007 - Now playing online -- a new Martian movie showing the planet rotating. The movie was made from four images taken by the Hubble Space Telescope's Wide Field Planetary Camera 2, built and designed by JPL. The images were taken within 36 hours of today's closest approach to Earth by Mars. The camera captured the views when Mars was just 88 million kilometers (55 million miles) away.

Rowan University Professor Seeing Red (Planet)

Glassboro NJ (SPX) Dec 18, 2007 - 'Tis the season for Rowan University physics and astronomy associate professor David Klassen. Mars season that is. December 24 marks the Mars opposition-the point at which Earth and Mars pass each other in their orbits. Visions of the planet will be dancing in Klassen's telescope in the coming days because Mars appears three to five times bigger in the sky during the opposition-quite a seasonal treat for observers of the planet.

Spirit Scouts Home Plate For Safe Haven

Pasadena CA (JPL) Dec 17, 2007 - Spirit has arrived at the north edge of Home Plate. The rover will spend the next few Martian days, or sols, scouting the edge of Home Plate and acquiring images of the slopes to determine the best site for Winter Haven 3, where Spirit will try to survive another season of minimal sunlight. Once the team selects a site, Spirit will drive down the north-facing edge of Home Plate and maneuver into position to achieve the highest northerly tilt possible.

Mars Orbiter Examines Lace And Lizard Skin Terrain

San Francisco CA (SPX) Dec 13, 2007 - Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet.

Building Blocks Of Life Formed On Mars

Washington DC (SPX) Dec 12, 2007 - Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists at the Carnegie Institution's Geophysical Laboratory have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impacts or more speculatively originated from ancient Martian microbes.

Software Helps Mars Rovers Find Winter Havens

Columbus OH (SPX) Dec 12, 2007 - New software is helping NASA find safe places for the Spirit rover to ride out future Martian winters -- and also plan where Spirit and its companion rover, Opportunity, will explore in the future. The steep Martian mesa dubbed Von Braun would be a safe haven, the software and data analysis determined -- but the path that Spirit would have to follow to get there is a little too risky to travel with winter on the way, explained Ron Li, professor of civil and environmental engineering and geodetic science at Ohio State University.

Mars Express Watches A Dust Storm Engulf Mars

Paris, France (ESA) Dec 12, 2007 - This summer, Mars suffered a titanic dust storm that engulfed the entire planet. The dust storm contributed to a temporary warming effect around Mars, which raised the temperature of the atmosphere by around 20-30C. However, the surface temperature of the planet itself dropped.

Clues From Antarctica Help With Search For Water On Mars

Columbus OH (SPX) Dec 11, 2007 - Scientists have gathered more evidence that suggests flowing water on Mars -- by comparing images of the red planet to an otherworldly landscape on Earth. In recent years, scientists have examined images of several sites on Mars where water appears to have flowed to the surface and left behind a trail of sediment. Those sites closely resemble places where water flows today in the McMurdo Dry Valleys in Antarctica, the new study has found.

Mars Rover Investigates Signs Of Steamy Martian Past

San Francisco CA (SPX) Dec 11, 2007 - Researchers using NASA's twin Mars rovers are sorting out two possible origins for one of Spirit's most important discoveries, while also getting Spirit to a favorable spot for surviving the next Martian winter. The puzzle is what produced a patch of nearly pure silica -- the main ingredient of window glass -- that Spirit found last May. It could have come from either a hot-spring environment or an environment called a fumarole, in which acidic steam rises through cracks.

Opportunity Grinds Into Rock In Victoria Crater

Pasadena CA (JPL) Dec 11, 2007 - Opportunity spent part of the past week carefully grinding a hole into the surface of a light-colored ring of rock inside Victoria Crater known as Smith, despite the previous loss of encoders that enabled two of the motors of the rock abrasion tool to operate under control of the tool's flight software.

NASA Study Reveals Less Water In Clouds Of Mars

Moffett Field CA (SPX) Dec 07, 2007 - Martian clouds may contain less water than previously thought, according to a new NASA study. New NASA laboratory measurements of simulated martian clouds reveal that scientists may have been overestimating the amount of water in the planet's atmosphere.

Spirit Breaks Free In Race For Survival

Pasadena CA (JPL) Dec 04, 2007 - In typical unflagging fashion, Spirit has managed to break free of piles of soil built up around the wheels in a low, sandy area that the rover's handlers have nicknamed Tartarus, after a deep, underworld dungeon in Greek mythology. Team members are pulling out all the stops to get Spirit to a winter location where, based on solar power projections, the rover has a chance at survival.
