Is Mars Hot or Cold?
2013-02-08 14:49:48

Alan McStravick for redOrbit.com - Your Universe Online With all the attention being paid to Mars, we are learning something new about the red planet almost daily. Each new revelation is pretty heady information. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold. The early days of Earth was marked by a climate that was both warm and wet, and mirrors what Mars was like some 3.5 billion years ago....

Hedgehog Rovers Will Bounce, Hop, Leap Their Way Over Martian Moon Phobos
2013-01-03 07:06:46

Lawrence LeBlond for redOrbit.com - Your Universe Online Stanford University researchers, working with NASA´s Jet Propulsion Laboratory (JPL) and MIT, have designed a new robotic platform that could be used to explore the moons of Mars. The platform consists of a mother spacecraft and anywhere from one to several spiky, spherical rovers that can be deployed on the surface of a moon, such as Phobos, where they can hop, roll and tumble their way across rugged terrain. Each rover,...

NASA's Curiosity Can Find Its Position With Martian Eclipses
2012-12-13 17:59:54

Lee Rannals for redOrbit.com — Your Universe Online Researchers say that if Curiosity ever loses its location on the surface of Mars, it could use eclipses to help it find its way. Researchers at the Complutense University of Madrid (Spain) have developed a method for helping Curiosity find its way around Mars by using Martian moons. "Observing these events offers an independent method for determining the coordinates of Curiosity," Gonzalo Barderas, researcher at UCM and...

Climate Models Work For Mars Too
2012-10-17 10:56:49

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well. Researchers from Planetary Science Institute in Tucson report they have found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of age and location. "Some public figures imply that modeling of global climate change on Earth is...

Martian Meteorite Reveals Atmospheric Secrets
2012-10-12 04:47:23

April Flowers for redOrbit.com - Your Universe Online An international team of researchers is examining a meteorite that landed 14 months ago in the Moroccan desert for information about Mars. Traces of the Martian atmosphere were trapped in the Tissint meteorite, according to the study led by the University of Alberta. “Our team matched traces of gases found inside the Tissint meteorite with samples of Mars´ atmosphere collected in 1976 by Viking, NASA´s Mars lander...

Mars Rover Images Interesting Rock Feature
2012-10-02 12:53:43

Lee Rannals for redOrbit.com - Your Universe Online Curiosity, at 54-days deep into its mission on Mars, recently shot back an image to NASA taken of an interesting rock called "Bathurst Inlet." The Martian rock is dark gray, and appears so fine-grained that the rover's Mars Hand Lens Imagers (MAHLI) camera cannot depict grains or crystals in it. NASA said this means if there are any grains or crystals at all, they are smaller than about 80 microns in size. The space agency said some...

Mars Weather Report At Gale Crater
2012-09-29 05:18:57

Lee Rannals for redOrbit.com - Your Universe Online NASA's Curiosity rover has sent back a Martian weather report, showing surprisingly mild daytime temperatures. The rover's Remote Environment Monitoring Station (REMS) is the latest Martian meteorologist, and it has been keeping NASA updated with the weather on the Red Planet around Gale Crater. The latest data shows the average daytime air temperatures have reached a peak of 42 degrees Fahrenheit on Mars around Curiosity....

Deimos Orbital Model Improved
2012-09-26 10:27:22

April Flowers for redOrbit.com - Your Universe Online 135 years ago, a scientist named Asaph Hall discovered Phobos and Deimos, two small moons orbiting Mars. Since then, the moons have been photographed innumerable times from Earth and from spacecraft, including recent measurements by the Mars Exploration Rovers panoramic cameras and the Mars Reconnaissance Orbiter. The orbit of Phobos, the inner moon, has been calculated to an accuracy of less than 1 kilometer. But, despite this...

Lee Rannals for redOrbit.com — Your Universe Online Researchers from the Niels Bohr Institute have dated climate history for Mars for the first time. The ice caps on Mars' poles are miles thick, composed of ice and dust and contain layers that can be seen in cliffs and valley slopes. The layers are believed to reflect past climate on Mars, in the same way that Earth's climate history can be seen from the ice caps on Greenland and Antarctica. The scientists were able to...

Meteor Shower To Coincide With 'Supermoon' This Weekend
2012-05-05 12:21:09

Peak viewing conditions for the Eta Aquarid meteor shower, which occurs annually when Earth passes through the debris trail from Halley's Comet, will begin on the evening of May 5 and last until the early morning hours on May 6, NASA officials announced earlier this week. The meteor shower, which is caused by the cosmic debris from the comet burning up in our planet's atmosphere, produces between 40 and 60 meteors per hour under ideal conditions, the US space agency said in a statement on...

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...
