New Study Finds That Lava Carved The Giant Valleys Of Mars
2014-05-13 07:17:31

April Flowers for redOrbit.com - Your Universe Online In 1877, Giovanni Schiaparelli of Italy first described what he called "canali" on the surface of Mars. These straight landforms on the Martian equatorial region form a conspicuous net-like system of deep gorges called the Noctis Labyrinthus, which is clearly visible. Noctis Labyrinthus leads into the even larger Valles Marineris canyon, which is 2500 miles long,  125 miles wide and 4 miles deep. Together, these two systems would span...

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...

April Flowers for redOrbit.com - Your Universe Online NASA's Curiosity Rover has drilled into a slab of Martian sandstone from which portions of rock powder will be delivered into the rover's internal instruments. Early Tuesday, Curiosity rover team members at NASA's Jet Propulsion Laboratory (JPL) received confirmation of the rover's third successful acquisition of a drilled rock sample from the target rock "Windjana." Created by Curiosity's hammering drill, the new hole is 0.63 inch...

Preparatory Drilling Test on Martian Target Windjana
2014-05-01 08:55:24

UPDATE: May 1, 2014 (9:00AM CDT) NASA's Curiosity Mars rover performed a "mini-drill" operation Tuesday, April 29, on the rock target under consideration for the mission's third sample-collection drilling. This preparatory activity produced a hole about eight-tenths of an inch (2 centimeters) deep, as planned, in the target called "Windjana." The rover team plans to decide whether to proceed with deeper drilling of this rock in coming days. Guy Webster, NASA The team operating...

Mars Crater May Have Been Wet In The Relatively Recent Past
2014-04-26 05:08:42

April Flowers for redOrbit.com - Your Universe Online Well preserved gullies and debris flow deposits in a crater on the southern hemisphere of Mars are providing new evidence through their geomorphological attributes that they were formed by the action of liquid water in relatively recent geological times, according to a new study from the University of Gothenburg. On Earth, water becomes a single-phase unit and a flow of debris is created when the sediment on a slope is saturated with...

asteroids seen from mars surface
2014-04-25 05:47:16

Guy Webster, Jet Propulsion Laboratory A new image from NASA's Curiosity Mars rover is the first ever from the surface of Mars to show an asteroid, and it shows two: Ceres and Vesta. These two -- the largest and third-largest bodies in the asteroid belt between Mars and Jupiter -- are the destinations of NASA's Dawn mission.  Dawn orbited Vesta in 2011 and 2012, and is on its way to begin orbiting Ceres next year. Ceres is a dwarf planet, as well as an asteroid. Ceres and Vesta...

Plant Material Stored In Impact Glass Could Reveal Much About Ancient Earth, Mars
2014-04-20 07:04:38

redOrbit Staff & Wire Reports - Your Universe Online The discovery of biodata encapsulated in molten glass resulting from asteroid and comet impacts millions of years ago not only provides information about the climate and life forms of the ancient Earth, but has also led to hopes that similar preserved organic compounds will be discovered on Mars. Fragments of leaves and other organic compounds were found lodged inside glass created by ancient impacts in Argentina by Brown...

Selfie From Mars Opportunity Rover

Guy Webster, NASA's Jet Propulsion Laboratory In its sixth Martian winter, NASA's Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning effects of wind events in March boosted the amount of electricity available for the rover's work. A new self-portrait from Opportunity's panoramic camera (Pancam), showing the cleaned arrays, is online at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18079...

Martian Meteorites Offer Evidence Of Early Atmosphere On Red Planet
2014-04-17 06:47:34

Lawrence LeBlond for redOrbit.com - Your Universe Online Martian meteorites that fell to Earth are revealing secrets of an early atmosphere on Mars that is hidden in the chemical signatures of each ancient rock. Geologists, who collected and studied 40 of these otherworldly rocks, have found an important key to how the atmospheres of Mars and Earth diverged very early in the evolution of the Solar System. The results of this study, published in the journal Nature, will help guide...

Hematite (AE) or haematite (BE) is the mineral form of Iron (III) oxide, (Fe2O3), one of several iron oxides. The ore sometimes contains slight amounts of titanium. When shaped into ornaments, it is often called black diamond. Hematite is a very common mineral, coloured black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include Bloodstone, Iron Rose, Kidney Ore, Martite, Paint Ore, Specularite (Specular Hematite), Rainbow Hematite...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...

Extraterrestrial Life -- Extraterrestrial life is life beyond planet Earth (apart from humans travelling in space, and living organisms they bring along or send). There are many questions about extraterrestrial life, including: -- Does it exist? -- Where? -- What kind? -- Could there be non-carbon based life forms, e.g. life forms based on other elements like silicon (See Carbon chauvinism)? -- How does life differ depending on the type of structure (unicellular life,...

Drake Equation -- The Drake equation (also known as the Green Bank equation) is a famous result in the speculative fields of xenobiology and the search for extraterrestrial intelligence. This equation was devised by Dr. Frank Drake in the 1960s in an attempt to estimate the number of extraterrestrial civilizations in our galaxy with which we might come in contact. The main purpose of the equation is to allow scientists to quantify the uncertainty of the factors which determine the number...

Olympus Mons -- Olympus Mons is the tallest mountain in the solar system, at 25 km. Located on Mars, and officially called by its Latin name Olympus Mons. It is named for the mountain on Earth. Olympus Mons is an apparently extinct shield volcano, the result of highly fluid magma flowing out of volcanic vents over a long period of time, and is much wider than it is tall; the average slope of Olympus Mons' flanks is very gradual. The Hawaiian islands are an example of similar shield...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
