Robert Zubrin's Mars Gashopper Airplane
Fraser Cain writes "Universe Today has a story about Robert Zubrin's (Mars Society President) Martian Gashopper Aircraft proposal to NASA. It uses solar power to liquefy carbon dioxide and then use it as a propellant to take off, fly hundreds of km above the surface of Mars like an airplane, and then land vertically again." -

Lunar Space Elevator Instead?
koa writes "We have all seen articles on building a Space Elevator on the earth, how about this article about experimenting with the Moon first since the technology we have available to us is sufficient, as the Moon's gravity is 1/6th that of Earth's (the cable weight would require less exotic materials such as carbon nano-tubes). One could make a very good argument for commercialization of Space if getting materials to and from the Moon's surface was vastly cheaper and easier." -
Venus/Jupiter Conjunction Tomorrow
TigerNut writes "I've been watching Venus and Jupiter creep closer together in the morning sky for the last few weeks, and tomorrow will be their closest approach, according to this table. The table also indicates this will be the closest that Venus and Jupiter will appear until 2014. Happy viewing! There's more on the conjunction at Universe Today." -
How About a Gigapixel Digital Camera?
vcullen writes "Ever wondered where digital cameras will end up? What about a 1 Gigapixel digital camera? It would certainly beat the latest array of new digital cameras - the biggest of which only has an 8.2MP sensor! The 1 Gig Digital Camera might not quite fit in your pocket but the thought of it does make one's mind spin a little. The European Space Agency is building this massive camera (actually it's made from 170 cameras) for its Gaia space telescope, due for launch in 2010. Why? They want to map the entire universe 'down to a resolution one million times fainter than the human eye can see.'" -
Physicists Postulate Existance of New Particle
corngrower writes "University of Washington physicists postulate the existence of a new particle called the acceleron which links dark energy with the neutrino. The theory offers an explanation for the recent discovery of the accelerating expansion of the universe." -
Hubble Photo of Sedna Suprises Astronomers
waynegoode writes "Soon after the announcement of the discovery of Sedna, the solar system's furthest object and planet wanna-be, the Hubble Space Telescope was pointed at it to answer some of the many questions its discovery generated. The photos were released today and are surprising for what they don't show--a moon. Astronomers were certain it had a moon because of its slow rotation. "I'm completely baffled at the absence of a moon," says Michael Brown, Sedna's discoverer. Story and photo at Universe Today, hubblesite and NASA press release." -
Asteroid Impact Simulator Available
crem_d_genes writes "Scientists at the University of Arizona's Lunar and Planetary Laboratory have developed an online program that calculates the effects of an asteroid impact that can be customized for several parameters. Results and the frequency of the type of event you have selected are displayed with an explanation of what they mean. A news briefing of the full story is available." -
Mice In Space
benmcgruer writes "Space.com is reporting on the Mars Gravity Biosatellite Program. This international, student-lead, project aims to explores the topical issue of biological response to low gravity, specifically the 0.38-g found on Mars, by building and launching their own satellite, complete with 15 mice. NASA, Fark.com and Universe Today also have coverage." -
NBC Signs Up To Broadcast "Destination Mir"
Fraser Cain writes: "Mark Burnett, producer of the hit show "Survivor," has sold the rights to his new show, "Destination Mir" to NBC for $40 million. The show will follow a group of 13-15 would-be cosmonauts as they train for a trip to the Mir space station." I love this line from the article: "Each week, a contestant will be removed by Russian Space Officials until the final winner is launched into orbit on a special, live broadcast." I certainly hope the Russian Space Officials are gentle with both the runners up and the eventual winner. -
