So: they don't have an e-mail address for you, or a phone number, and you throw out all postal mail you get from them. How do you suggest they contact you if there's a problem? I wouldn't be in favor of overuse of this method, but if you've got a 'bot running on your system, you're part of a problem and maybe something a little heavy-handed is warranted.

I think this is a good method. It's a lot harder to ignore than other ways that you've suggested (how much of an automated phone message would you listen to if it started as "This is a courtesy call from Comcast internet services ..."). HTTP also a service that people are more likely to use every day, and there's little chance that an errant spam filter will block it.

A risk - in theory - is that when people see this popup, they'll say "I'm supposed to not interact with these things" and just click "Close," rather than understanding what it says. On the other hand, if your computer is infected with some sort of 'bot, you probably click through things like this anyway.

Microwave Map of Entire Moon Revealed 82

Zothecula writes "The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang'E-1 is China's first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution."

The Sun Unleashes Coronal Mass Ejection At Earth 220

astroengine writes "Yesterday morning, at 08:55 UT, NASA's Solar Dynamics Observatory detected a C3-class flare erupt inside a sunspot cluster. 100,000 kilometers away, deep within the solar atmosphere (the corona), an extended magnetic field filled with cool plasma forming a dark ribbon across the face of the sun (a feature known as a 'filament') erupted at the exact same time. It seems very likely that both eruptions were connected after a powerful shock wave produced by the flare destabilized the filament, causing the eruption. A second solar observatory, the Solar and Heliospheric Observatory, then spotted a huge coronal mass ejection blast into space, straight in the direction of Earth. Solar physicists have calculated that this magnetic bubble filled with energetic particles should hit Earth on August 3, so look out for some intense aurorae — a solar storm is coming."

Decades-Old Soviet Reflector Spotted On the Moon 147

cremeglace writes "No one had seen a laser reflector that Soviet scientists had left on the moon almost 40 years ago, despite years of searching. Turns out searchers had been looking kilometers in the wrong direction. On 22 April, a team of physicists finally saw an incredibly faint flash from the reflector, which was ferried across the lunar surface by the Lunokhod 1 rover. The find comes thanks to NASA's Lunar Reconnaissance Orbiter, which last month imaged a large area where the rover was reported to have been left. Then the researchers, led by Tom Murphy of the University of California, San Diego, could search one football-field-size area at a time until they got a reflection."

Signs of Water Found On Saturnian Moon Enceladus 79

Matt_dk writes "Scientists working on the Cassini space mission have found negatively charged water ions in the ice plume of Enceladus. Their findings, based on analysis from data taken in plume fly-throughs in 2008 and reported in the journal Icarus, provide evidence for the presence of liquid water, which suggests the ingredients for life inside the icy moon. The Cassini plasma spectrometer, used to gather this data, also found other species of negatively charged ions including hydrocarbons."

Which is a great thing. LEO is something that private companies can do (or are very near being able to do), so there's no reason to compete against them. So I'm good with the part about shifting that part of the responsibility away from NASA.

At the same time, I don't see where the exploration role fits in to this new plan. That's the part that concerns me.

Having said that, so far all of the things that we've heard have been leaks and conjecture. So it's probably not fair to condemn (or applaud) the plan until we've heard what it actually is.

Comment Re:Privatisation (Score 1) 450

In the earliest days of private air travel, one of the biggest and most reliable customers was the government - the US Postal Service. The government can create an initial market that allows private companies to be created and innovate to become cheaper and more reliable; that innovation creates makes the platform reliable and affordable, which encourages private market demand.

That's not to say that I support this decision. As stated by some other posters here, private (or publicly traded) companies aren't interested in the sort of exploration for exploration's sake that the government can do - they only "explore" if there is a known profit to be made. The problem with space exploration is that despite any evidence of great things sent back by robotic probes, there aren't really any clear avenues for profit in deep space missions. That doesn't mean that the opportunities aren't there, it just means that we don't know about them - the government can help us find them, and along the way the government can share what it learned with the nascent commercial spaceflight industry - to the benefit of all.

Or we can scrap it and hope for the best. America has already lost in the commercial satellite launch business; now we're on track to lose the rest - then what? We are one of two nations on this planet that have both the means and experience to create a great human spaceflight program. Are we going to throw that away?

NASA Tests Flying Airbag 118

coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."
