Cuiosity Rover Eyes Bonanza King
2014-08-17 08:44:42

Guy Webster, Jet Propulsion Laboratory The team operating NASA's Curiosity Mars rover has chosen a rock that looks like a pale paving stone as the mission's fourth drilling target, if it passes engineers' evaluation. They call it "Bonanza King." It is not at the "Pahrump Hills" site the team anticipated the rover might reach by mid-August. Unexpected challenges while driving in sand prompted the mission to reverse course last week after entering a valley where ripples of sand fill...

DC Agle, Jet Propulsion Laboratory and David Steitz, NASA Headquarters NASA's Low-Density Supersonic Decelerator (LDSD) project successfully flew a rocket-powered, saucer-shaped test vehicle into near-space in late June from the U.S. Navy's Pacific Missile Range Facility on Kauai, Hawaii. The goal of this experimental flight test, the first of three planned for the project, was to determine if the balloon-launched, rocket-powered, saucer-shaped, design could reach the altitudes and...

Meteorite violent origins
2014-08-09 05:13:23

April Flowers for redOrbit.com - Your Universe Online Seven years ago, the Bunburra Rockhole Meteorite fell on the Western Australia (WA) side of Nullarbor Plain and was captured on camera. A new study, published in Geochimica and Cosmochimica Acta, indicates that the unique characteristics of the meteorite suggest it originates from a never-before-identified asteroid. The research team — comprised of Curtain University's Associate Professor Fred Jourdan, Professor Phil Bland and Dr....

Monash University Researchers are a step closer to understanding the birth of the sun. Published in Science, the team led by Dr Maria Lugaro and Professor Alexander Heger, from Monash University, have investigated the solar system's prehistoric phase and the events that led to the birth of the sun. Dr Lugaro, from the Monash Centre for Astrophysics, said the team used radioactivity to date the last time that heavy elements such as gold, silver, platinum, lead and rare-earth elements...

Guy Webster, Jet Propulsion Laboratory As it approaches the second anniversary of its landing on Mars, NASA's Curiosity rover is also approaching its first close look at bedrock that is part of Mount Sharp, the layered mountain in the middle of Mars' Gale Crater. The mission made important discoveries during its first year by finding evidence of ancient lake and river environments. During its second year, it has been driving toward long-term science destinations on lower slopes of Mount...

Companion planets

April Flowers for redOrbit.com - Your Universe Online For humans, having a companion in our later years can help increase our lifespan. A new study led by the University of Washington shows that having a companion might also extend the life of some Earth-sized planets. As a planet ages, it cools and the molten core solidifies. This leads to a dwindling of the inner heat-generating activity that keeps the planet habitable by regulating carbon dioxide to prevent runaway heating and...

Carl Edward Sagan (November 9, 1934 - December 20, 1996) was an American astronomer who pioneered exobiology and promoted the Search for Extraterrestrial Intelligence (SETI) and science in general. He is less well known for his skepticism. Born in Brooklyn, New York, Sagan attended the University of Chicago, where he received a bachelor's degree (1955) and a master's degree (1956) in physics, before earning his doctorate (1960) in astronomy and astrophysics. He taught at Harvard University...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...

Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...
