Virgin Galactic spaceship
Virgin Galactic strikes deal with Swedish government
(Jan 30, 2007)


The Swedish government on Jan. 26 announced an agreement with suborbital space-tourism company Virgin Galactic that Swedish officials believe will lead to midsummer and mid-winter flights of Virgin's SpaceShipTwo vehicle to observe the Aurora Borealis from Sweden. The agreement, signed at the proposed future launch site in Kiruna, Sweden, calls for no exchange of funds.

Hubble Space Telescope
Hubble's main camera shuts down
(Jan 30, 2007)


The main camera on the Hubble space telescope has shut down after an electrical failure, NASA has said. Astronomers are calling the malfunction of the Advanced Camera for Surveys a "great loss" as it has taken the clearest pictures yet of the universe. Scientists for the US space agency said only one-third of the camera's capabilities are likely to be restored. A new camera is to be installed during a planned space shuttle mission to the Hubble telescope in 2008.

Elysium Planitia
Frozen sea may harbour Mars life
(Jan 29, 2007)


A frozen sea found on Mars is one of the most promising places to look for life on the Red Planet, scientists say. But planned missions designed to search for microbes below the Martian surface will not drill deep enough to find living cells, the UK team has said. Researchers at University College London say that microbes in the first couple of metres of Martian soil would be killed off by intense radiation. Life might survive deeper down, where conditions are more benign, they think.

HERA particle accelerator
Last-gasp test could reveal dark matter
(Jan 28, 2007)


The HERA particle accelerator in Germany is set to call it quits in June, but a lone physicist is now campaigning for HERA to have one last hurrah. He claims it could discover a particle believed by many to account for the unseen dark matter that constitutes the bulk of the universe's mass. The particle in question is the axion.

NASA studies early Moon shot for new space capsule
(Jan 27, 2007)


NASA is studying a variant of its planned Ares 5 heavy-lift rocket that would enable an Apollo 8-like trip around the Moon in the 2015 time frame. Scott Horowitz, NASA’s associate administrator for exploration systems, said he asked engineers at the agency’s Marshall Space Flight Center to study a rocket design that would combine the Ares 5 main stage with the Ares 1 upper stage to permit an around-the-Moon-and-back shakeout flight of the Orion Crew Exploration Vehicle several years ahead of the first lunar landings.

Hints of huge water reservoirs on Mars
(Jan 26, 2007)


Mars is losing little water to space, according to new research, so much of its ancient abundance may still be hidden beneath the surface. Dried up riverbeds and other evidence imply that Mars once had enough water to fill a global ocean more than 600 metres deep, together with a thick atmosphere of carbon dioxide that kept the planet warm enough for the water to be liquid. But the planet is now very dry and has a thin atmosphere.

Sun
Sun's fickle heart may leave us cold
(Jan 25, 2007)


There's a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 years – exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star's core. Robert Ehrlich of George Mason University in Fairfax, Virginia, modelled the effect of temperature fluctuations in the sun's interior.

Astronauts exploring on the Moon's surface
Moon astronauts face X-ray danger
(Jan 24, 2007)


Future lunar astronauts could be harmed by X-ray outbursts from the Sun that occur without warning and can deliver dangerous doses of radiation in just a few minutes, a new study says. The researchers suggest that lunar rovers be equipped with metal shields that astronauts could duck behind during such events.

Exploding robots may scout hazardous asteroids
(Jan 23, 2007)


A fleet of exploding probes could prepare the way for warding off hazardous asteroids. Several of the small spherical robots would land on a single asteroid, some exploding while others listen for vibrations that could reveal the object's inner structure. NASA has a list of more than 800 asteroids considered to be potentially hazardous because their orbits carry them close to Earth's.

ion beam propulsion
Ride the ion train from the Moon to Earth
(Jan 22, 2007)


Spacecraft could one day be propelled by ion beams shooting up from the Moon, according to a recent concept study. Other spacecraft, such as Deep Space 1 and SMART-1, have flown with ion engines, which work by stripping electrons off gas atoms and accelerating the ions with an electric field. The ions create thrust as they are shot out of the engine.
