Ask Slashdot: How Did You Experience The Solar Eclipse?
NASA claims they set a record Monday with 40 million views of their eclipse coverage (12.1 million unique) and more than 2 million simultaneous views. Now Slashdot reader xmas2003 asks: "What did /.'ers do to experience this rare incredibly cool event and how did it turn out?" SmarterEveryDay Destin gets great geek cred for watching the ISS transit the eclipsed sun [YouTube] while we were fortunate to have an incredible experience on 40 acres of farmland watching the Total Solar Eclipse near Tryon, Nebraska -- here's a complete video of [a darkening crowd watching] the totality event from the middle of nowhere. While the pics/video are cool, the real-life experience of actually being there in person is even 100X better -- highly recommend you try to attend a future total solar eclipse!.
In my town it was cloudy all morning -- though I got a postcard from friends experiencing "the path of totality" in Idaho City. But how about you? How did you experience this week's solar eclipse? -
NASA Will Create Fake Red And Green Clouds Near Virginia (cnn.com)
"We have scrubbed today, June 4, due to clouds," NASA tweeted hours before sunrise on Sunday, adding later that "The next launch attempt for the Terrier-Improved Malemute is no earlier than June 11 pending range availability." So they're still waiting for the right weather to launch a very unique experiment. An anonymous reader quotes CNET: The early morning hours on the U.S. East Coast might be unusually colorful as NASA plans to produce artificial blue-green and red clouds that may be visible from New York to North Carolina... It's a test of a new system that helps scientists study the auroras and ionosphere. A NASA sounding rocket (a small, sub-orbital rocket often used in research) will launch from Wallops Flight Facility off the coast of Virginia and release several soda-sized canisters of vapor tracers in the upper atmosphere that may appear as colorful clouds. The tracers use vapors made up of lithium, barium and tri-methyl aluminum that react with other elements in the atmosphere to glow, letting researchers visually track the flows of ionized and neutral particles. It's a bit like being able to dye the wind or ocean currents to be able to get a visual picture.
When NASA does perform its launch, CNN adds that "If you're near the eastern U.S. coast, look toward the eastern horizon. The farther you are from the launch location, the lower the clouds will appear on the horizon." Basically, try to adjust your gaze towards Virginia's eastern shore -- and if you're not on the east coast, NASA will be livestreaming the launch and posting updates on Facebook and Twitter.

Urthecast Brings You Earth Images and Videos from the ISS (Video)
Most of us probably won't ever visit the International Space Station (ISS) and look down at the Earth (motto: "The only planet we know has beer, so let's not ruin it"). Looking at pictures and videos made by cameras mounted on the ISS is about as close as we're going to get. There's already an ISS HD Earth Viewing Experiment on Ustream, but Urthecast is putting out higher-definition images than what you see on Ustream, and has plans to put out even clearer images and video before long. While Urthecast is likely to accumulate plenty of "oohs" and "aahhs" as it rolls along, according to CEO Scott Larson their real objective is to sell imagery -- and not necessarily just from the visible light band of the overall spectrum -- to industrial and government users. People like us are still invited to look at (and marvel at) lovely images of our planetary home.
NOTE: Today's video is about 4:30 long. If you want to watch and listen to more of Mr. Larson, we have a second "bonus" (Flash) video for you. Or you can read the transcript, which covers both videos. -
How To View the Antares Launch
An anonymous reader points out NASA's info page on the Anatares rocket launch happening later today. NASA's Wallops Flight Facility and Virginia's Mid-Atlantic Regional Spaceport are set to support the launch of Orbital Sciences' Antares rocket at 6:45 p.m. EDT, October 27. The Antares rocket will carry Orbital's Cygnus cargo spacecraft, loaded with some 5,000 pounds of supplies and experiments, to the International Space Station. The launch may be visible, weather permitting, to residents throughout the mid-Atlantic and Northeast regions of the United States. Here's a visibility map of launch. Public viewing of the launch will be available at the NASA Visitor Center at Wallops and at the Chincoteague National Wildlife Refuge/Assateague Island National Seashore. Here's more information about the Visitors Center, including directions, and information on viewing sites recommended by the Eastern Shore of Virginia Tourism Commission. Live coverage of the mission is scheduled to begin at noon on the Wallops Ustream site." -
CubeSat Launch Visible Around U.S. East Coast Tonight
Hugh Pickens DOT Com writes "Brad Lendon reports at CNN that 29 satellites, the most ever launched at one time, will be aboard a single Minotaur I rocket scheduled to lift off from NASA's Wallops Flight Facility in Virginia Tuesday night at 7:30 pm. The main payload will be the Air Force's Space Test Program Satellite-3, plus 28 tiny satellites called CubeSats about 4 inches on each side, weighing about 3 pounds and with a volume of about a quart. The cubesats will include Ho`oponopono-2 from the University of Hawaii to continue a long-existing radar calibration service for the 80 plus C-band radar tracking stations distributed around the world. It will also have CAPE-2 from the Cajun Advanced Picosatellite Experiment, to give students at the University of Louisiana at Lafayette the opportunity to research, design, develop, and maintain a low earth orbiting satellite, and SwampSat from the University of Florida to advance the TRL (Technology Readiness Level) of CMGs (Control Moment Gyroscopes) appropriate for smallsats. Among the CubeSats is the TJ3Sat, the first satellite made by high-schoolers to go into space, built by the students of Thomas Jefferson High School for Science and Technology in Alexandria, Virginia. It will give students and other amateur radio users the opportunity to send and receive data from the satellite. Approved text strings will be transmitted to the satellite, and the resulting voice interpretation will be relayed back to Earth over an amateur radio frequency using the onboard Stensat radio. Orbital says the 29 satellites should achieve orbit in a little less than 12½ minutes after the rocket ignites. NASA says the launch may be visible from northern Florida to southern Canada and as far west as Indiana. Live coverage of the launch is available via UStream beginning at 6:30 p.m. EST on launch day." -

Asteroid 2012 DA14 Approaches
Today at about 19:25 UTC (2:25 PM EST), Asteroid 2012 DA14 will make its closest approach to Earth, passing a mere 27,650 kilometers above the surface — closer than our satellites in geosynchronous orbit. NASA is broadcasting a live-steam showing the asteroid from an Observatory, and will have coverage on NASA TV starting about a half-hour before closest approach. The Planetary Society will be broadcasting a live webcast, and Phil Plait will be hosting a Google+ Hangout. NASA has also compiled a nice post filled with information about the asteroid, including trajectory diagrams, animated videos of the path, and answers to question about 2012 DA14. You can also watch it move at 50x actual speed through a telescope. They take pains to note that there is no danger of the asteroid striking the planet today, or any time in the forseeable future. Its next notably close approach in 2046 will only bring it about a million kilometers away. What makes 2012 DA14 significant is that it's rather large — it's 45 meters across and weighs about 130,000 metric tons. It's also moving about 7.8 kilometers per second relative to Earth. "To view the asteroid, you will need a good pair of binoculars, or even better, a moderately powered telescope. During the closest approach, and dependant on local weather, the asteroid will be visible from parts of Europe, Africa and Asia. The asteroid will appear to be moving relatively quickly as it crosses the sky from the south to the north." NASA says this morning's meteor event in Russia was unrelated. -
McAfee Is Doing a Live Broadcast Tonight
paysonwelch writes "John McAfee, famed antivirus software pioneer and human rights advocate, today announced that he will host a news conference to ask the world for its protection against the Government of Belize. On his official blog, whoismcafee.com, Mr. McAfee has accused the Belize government of widespread corruption. Because of this, Mr. McAfee feels that he will be in grave danger if he were to be returned to there." -
Email Offline At the Home of Sendmail
BobJacobsen writes "The UC Berkeley email system has been either offline, or only providing limited access, for more than a week. How can the place where sendmail originated fall so far? The campus CIO gave an internal seminar (video, slides) where he discussed the incident, the response, and some of the history. Briefly, the growth of email clients was going to overwhelm the system eventually, but the crisis was advanced when a disk failure required a restart after some time offline. Not discussed is the long series of failures to identify and implement the replacement system (1, 2, 3, 4). Like the New York City Dept. of Education problem discussed yesterday, this is a failure of planning and management being discussed as a problem with (inflexible) technology. How can IT people solve things like this?" -
NASA Rover 'Curiosity' Set For Saturday Launch
arcite writes "The Mars Science Laboratory Rover 'Curiosity,' an SUV-sized rover packed to the gills with the latest scientific instruments and an innovative landing system, is set to launch tomorrow. As the heaviest and largest Mars rover to date, if it is successful in touching down on the red planet, it will be the best bet yet for NASA to find signs of life. Stuffed with turkey and burned out on holiday shopping, Geeks everywhere will be watching the skies above (or the livestream here) and wishing NASA's Curiosity godspeed!" -
NYPD Dismantling Occupy Wall Street Encampment
First time accepted submitter Red_Chaos1 was the first to write with news that, as of around 06:30 UTC, the NYPD appears to have begun removing the encampment of Occupy Wall Street. At 06:34 UTC the Mayor's office issued a tweet declaring: "Occupants of Zuccotti should temporarily leave and remove tents and tarps. Protesters can return after the park is cleared." Around 07:15 UTC the first of several large dumpsters were deposited and the police began throwing tents and other debris into it. Reports also indicate that a Long Range Acoustic Device is on the premises. The police are using helicopters and physical barriers to prevent news coverage, but the Occupiers are streaming the events (alternative stream; #occupywallstreet on irc.indymedia.org is also rather active for those who don't fancy flash or twitter.) As of 09:15 or so, the situation according to those near NYC is that the park has more or less been cleared. -
First Two-Legged Robot Marathon is Under Way In Osaka, Japan
gregg writes "Five knee-high androids have crossed the starting line in the world's first marathon for two-legged robots.The contestants are expected to take four days to complete the course, which involves 423 laps of an indoor track." The live robot marathon video feed will make you realize that not all robots are worthy of fear. Or even worth watching for more than a few minutes. -
Flash Destroyer Tests Limit of Solid State Storage
An anonymous reader writes "We all know that flash and other types of solid state storage can only endure a limited number of write cycles. The open source Flash Destroyer prototype explores that limit by writing and verifying a solid state storage chip until it dies. The total write-verify cycle count is shown on a display — watch a live video feed and guess when the first chip will die. This project was inspired by the inevitable comments about flash longevity on every Slashdot SSD story. Design files and source are available at Google Code." -
Networked Christmas Tree Controlled By Twitter
An anonymous reader writes "What's Twitter good for? How about crowd sourcing control of your Christmas tree. Dangerous Prototypes built an open source, networked Christmas tree that you can control from Twitter. Send a color or hexadecimal color code to @tweet_tree, then watch the color change on the live video stream. This project is based on an updated version of the open source business card size web server covered previously."
