Changes In Martian Sand Dunes Monitored By Mars Orbiter
2012-05-09 15:13:05

NASA's Mars Reconnaissance Orbiter has revealed that movement in sand dune fields on the Red Planet occurs on a surprisingly large scale, about the same as in dune fields on Earth. This is unexpected because Mars has a much thinner atmosphere than Earth, is only about one percent as dense, and its high-speed winds are less frequent and weaker than Earth's. For years, researchers debated whether sand dunes observed on Mars were mostly fossil features related to past climate, rather than...

Evidence that there was once water on Mars continues to mount, as the European Space Agency (ESA) and researchers from a U.S. university became the latest to tout findings supporting the theory that there was once H2O on the Red Planet. On Friday, the ESA announced in a press release that their Mars Express space exploration mission had sent back images from the planet which had apparently been formed in part by flowing liquid. The images are of the western part of a massive basin on the...

Evidence of Ancient Water Discovered at Mars Crater
2012-05-04 04:26:16

NASA's Mars Exploration Rover Opportunity discovered evidence of ancient water at the rim of an ancient impact crater on the planet's surface, according to a new report published in the May 4 edition of the journal Science. The rover, which completed its original three-month mission eight years ago and reached the 4 billion year old Endeavour crater last summer, found evidence that the impact that had originally created the crater released heated, underground water that had deposited zinc...

Less Than 100 Days Remain Until Curiosity Lands On Mars
2012-04-29 04:23:14

The NASA Mars Science Laboratory (MSL) and the Curiosity rover are now less than 100 days away from landing on the surface of the Red Planet, officials at the US space agency announced on Friday. The one-ton Curiosity and the craft ferrying it to Mars reached the T-minus 100 day mark at 10:31pm PDT on Friday, officials at the Jet Propulsion Laboratory (JPL) in Pasadena, California said over the weekend. At that time, it was approximately 119 million miles from its destination, travelling...

Mars Science Laboratory Adjusts Path, Tests Instruments
2012-03-27 13:46:47

NASA's Mars Science Laboratory spacecraft, halfway to Mars, adjusted its flight path today for delivery of the one-ton rover Curiosity to the surface of Mars in August. Tests completed aboard Curiosity last week confirmed the health of science instruments the mission will use to learn whether an area holding an extensive record of Martian environmental history has ever offered conditions favorable for microbial life. In the second of six planned trajectory correction maneuvers during...

NASA Planetary Science Budget To Be Cut
2012-02-10 11:42:48

The Obama administration´s upcoming budget for NASA plans to cut $300 million out of the agency´s planetary science program, which could keep any planetary explorations, including Mars missions, grounded. If the budget proposal is adopted by Congress, it would most likely shelve NASA´s ability to participate in two upcoming Mars missions to be carried out in partnership with the European Space Agency (ESA). But even before any cuts have been unveiled, lawmakers are vowing...

Image 1 - Mars Rover Curiosity Carries A Penny For Camera Checkup
2012-02-08 05:18:49

The camera at the end of the robotic arm on NASA's Mars rover Curiosity has its own calibration target, a smartphone-size plaque that looks like an eye chart supplemented with color chips and an attached penny. When Curiosity lands on Mars in August, researchers will use this calibration target to test performance of the rover's Mars Hand Lens Imager, or MAHLI. MAHLI's close-up inspections of Martian rocks and soil will show details so tiny, the calibration target includes reference lines...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
