Dr. Tony Phillips, Science@NASA On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away - which would be like a comet passing about 1/3 of the distance between Earth and the Moon. The nucleus of the comet won't hit Mars, but there could be a different kind of collision. "We hope to witness two atmospheres colliding," explains David Brain of the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP). "This is a once in a lifetime event!"...

Curiosity Currently Traveling Through Ancient Glaciers On Mars
2014-06-26 03:13:27

FECYT - Spanish Foundation for Science and Technology 3,500 million years ago the Martian crater Gale, through which the NASA rover Curiosity is currently traversing, was covered with glaciers, mainly over its central mound. Very cold liquid water also flowed through its rivers and lakes on the lower-lying areas, forming landscapes similar to those which can be found in Iceland or Alaska. This is reflected in an analysis of the images taken by the spacecraft orbiting the red planet....

WASHINGTON, June 23, 2014 /PRNewswire-USNewswire/ -- NASA's Mars Curiosity rover will complete a Martian year -- 687 Earth days -- on June 24, having accomplished the mission's main goal of determining whether Mars once offered environmental conditions favorable for microbial life. http://photos.prnewswire.com/prnvar/20081007/38461LOGO One of Curiosity's first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an...

Despite Inhospitable Temperatures, Mars Lacks Frigid Wind Chills
2014-06-13 13:14:52

Brett Smith for redOrbit.com - Your Universe Online While the average planet-wide temperature on Mars is a frigid -81 degrees F and the lowest winter temperatures can get down to -184 degrees F, the Red Planet is much more hospitable than those temperatures would suggest due to a lack of wind chill, a new study has found. The wind chill temperature on Earth is always colder than the thermometer reading, but on Mars the temperature would feel as much as 200 degrees F hotter than the...

mars sees mercury transit
2014-06-11 09:14:23

Brett Smith for redOrbit.com - Your Universe Online Observers on Earth have tracked Venus and Mercury crossing the face of the Sun countless times, but the phenomenon has never been observed from another planet – until now. On Tuesday, NASA announced that its Curiosity Rover had captured the first-ever observations of Mercury moving across the face of the Sun – also called a planetary transit – using its two-eyed Mast Camera (MastCam). "This is a nod to the relevance of...

Opportunity rover covered in Martian dust
2014-05-07 07:50:51

redOrbit Staff & Wire Reports - Your Universe Online Dust is everywhere on Mars, and plays a key role in the red planet’s weather, according to a Texas A&M University researcher who has spent much of the past decade observing the phenomenon. Mark Lemmon, associate professor of atmospheric sciences at Texas A&M, has served as a camera operator on numerous Mars missions, especially those involving the Mars exploration rovers Spirit and Opportunity. Spirit landed in 2004 and...

Martians Or A Mere Technical Glitch? What's That Light Shining On Mars?
2014-04-09 04:19:20

redOrbit Staff & Wire Reports - Your Universe Online It’s the mystery that has space enthusiasts and the blogosphere buzzing: what exactly is the flash of light that appears on photos taken by NASA’s Mars Curiosity rover earlier this month? According to Rachel Katz of ABC News, the images were taken by the rover on April 2 and 3 at a location called “the Kimberley,” a spot where Curiosity could search for rock clues about ancient environments which could have been favorable...

NASA Preparing Martian Spacecraft For Close Passing Comet
2014-01-29 10:41:24

Brett Smith for redOrbit.com - Your Universe Online Scientists at NASA said they are busy prepping for observations of a comet that is expected to streak across the Martian sky later this year. Comet Siding Spring, officially dubbed C/2013 A1, is projected to pass about 10 times closer to Mars than any identified comet has ever flown past Earth. "Our plans for using spacecraft at Mars to observe comet Siding Spring will be coordinated with plans for how the orbiters will duck and...

Geminids Meteor Shower Broadcast Live
2014-01-02 13:51:06

Lee Rannals for redOrbit.com - Your Universe Online The Quadrantids meteor shower will be helping to kick off the new year with a bang, displaying up to 80 meteors per hour on Friday. The meteor shower will only last for a few hours on the morning of January 3. NASA said that only people in the northern hemisphere will be able to see the shower. “The Quadranids [sic], will present an excellent chance for hardy souls to start the year off with some late-night meteor watching,”...

Martian Debris May Also Be Found On Phobos
2013-11-12 04:17:26

[ Watch the Video: Phobos Mission Could Return With Bonus Martian Material ] redOrbit Staff & Wire Reports - Your Universe Online Call it the geological equivalent of a buy-one, get-one free special: a planned Russian mission to collect samples from the Martian moon Phobos could also net debris from the Red Planet itself, according to research appearing in the journal Space and Planetary Science. The study, which was authored by Brown University professor of geological sciences...

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

Perseids Meteor Shower -- Like most meteor showers, the Perseids are caused by comet debris. As comets enter the inner solar system, they are warmed by the sun and peppered by the solar wind, which produces the familar tails that stretch across the night sky when a bright comet is close to Earth. Comet tails are made of tiny pieces of ice, dust, and rock which are spewed into interplanetary space as they bubble off the comet's nucleus. When Earth encounters these particles on its...

The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...

The Planet Mars -- in astronomy, 4th planet from the sun, with an orbit next in order beyond that of the earth. Physical Characteristics Mars has a striking red appearance, and in its most favorable position for viewing, when it is opposite the sun, it is twice as bright as Sirius, the brightest star. Mars has a diameter of 4,200 mi (6,800 km), just over half the diameter of the earth, and its mass is only 11% of the earth's mass. The planet has a very thin atmosphere consisting...

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
