Revealed: Elon Musk Explains the Hyperloop, the Solar-Powered High-Speed Future of Inter-City Transportation - Businessweek
So, science, or science fiction? About a dozen people at Tesla and SpaceX have helped Musk with the design and checked the physics behind the Hyperloop. Again Video: Conard: Musk's Hyperloop Tempered By Technology Story: With SolarCity IPO, Elon Musk May Get Clean Tech Right Vance is a technology writer for Bloomberg Businessweek in Palo Alto, Calif
Rover Arm Delivers Rock Powder Sample Mar 13, 2015 NASA's Curiosity Mars rover used its robotic arm Wednesday, March 11, to sieve and deliver a rock-powder sample to an onboard instrument. NASA Spacecraft Detects Aurora and Mysterious Dust Cloud around Mars Mar 18, 2015 NASA's MAVEN spacecraft has observed an unexplained high-altitude dust cloud and aurora that reaches deep into the Martian atmosphere

This logistically complicated experiment is a pathfinder: It is teaching us how to build a whole network of launch sites to monitor Earth's atmosphere on continental scales. Automated software maintained by NASA's Meteoroid Environment Office calculates their orbits, velocity, penetration depth in Earth's atmosphere and many other characteristics
The Energy Story - Chapter 3: Resistance and Static Electricity
Around 600 BCE (Before the Common Era) Greeks noticed a strange effect: When rubbing "elektron" against a piece of fur, the amber would start attracting particles of dust, feathers and straw. Glass, however, when rubbed with silk, acquired what he termed "vitreous electricity." He thought that electricity repeled the same kind and attracts the opposite kind of electricity
Bad Astronomy
Speaking of which, the Dragon capsule (filled with supplies for the space station) on the Falcon 9 survived the initial event, and in fact they were getting telemetry from it until it dropped below the horizon, but it was certainly lost when it impacted the ocean at high speed. Advertisement Unlike the first close-up showing no craters at all, here you can see circular features that look very much like old impacts filled in by ice
Pluto a Planet Again? It May Happen This Year - The Crux
We have defined a criteria based on the needs of science in 2006; pretty egotistical given how little we know and the short time frame we as a species have been observing. And while taxonomy is a scientific pursuit, it involves drawing arbitrary lines based upon principles that are decided upon to force categorization and bestow labels on things
BLOODHOUND SSC
300 model rocket cars fired at Goodwood Festival of Speed The BLOODHOUND Education Team and Ambassadors from the British Army's REME helped children design, build and race 300+ rocket cars over the Goodwood Festival of Speed weekend. This will be the nerve centre of all the operations in the desert, with all of the communications, video and data being sent here from the car to be shared with the world
JPL Solar System Dynamics
Orbits Orbit diagrams for most solar system bodies as well as tables of orbital elements for the planets, planetary satellites, asteroids and comets are available
The Energy Story - Chapter 7: Electricity Transmission System
From these substations (like in the photo to the right), electricity in different power levels is used to run factories, streetcars and mass transit, light street lights and stop lights, and is sent to your neighborhood. The voltage is eventually reduced to 220 volts for larger appliances, like stoves and clothes dryers, and 110 volts for lights, TVs and other smaller appliances
Comets: 3,354 Orbiting spacecraft such as SOHO have raised this tally in recent years by catching the comets as they plunge toward the Sun - and sometimes vaporize. Dwarf Planets: 5 This new class of worlds helps us categorize objects that orbit the Sun but aren't quite the same as the rocky planets and gas giants in our solar system
Solar Panels from Wholesale Solar
California Leads the Nation In 2006, California made a major long-term commitment to solar power by passing the California Solar Initiative, a ten-year incentive program with the goal of installing 3,000 megawatts of solar panels on the equivalent of one million rooftops. Vanguard I, the first solar-powered satellite celebrated its 53rd birthday this year, setting mileage records and holding the title of being the oldest artificial satellite still in orbit
The sun is about 26,000 light-years from the center of the Milky Way Galaxy, which is about 80,000 to 120,000 light-years across (and less than 7,000 light-years thick). The Planets The nine planets that orbit the sun are (in order from the Sun): Mercury, Venus, Earth, Mars, Jupiter (the biggest planet in our Solar System), Saturn (with large, orbiting rings), Uranus, Neptune, and Pluto (a dwarf planet or plutoid)
Solar System, Solar System Information, Facts, News, Photos -- National Geographic
Search for Other Earths In an astronomical breakthrough, scientists have begun discovering planet after planet circling around distant stars as the search narrows for a world like our own. When Pluto is near the sun, it has a thin atmosphere, but when Pluto travels to the outer regions of its orbit, the atmosphere freezes and collapses to the planet's surface
Pluto Not a Planet, Astronomers Rule
How to Use XML or RSS National Geographic Daily News To-Go Listen to your favorite National Geographic news daily, anytime, anywhere from your mobile phone. "There are finally, officially, eight planets in the solar system." In a move that's already generating controversy and will force textbooks to be rewritten, Pluto will now be dubbed a dwarf planet
Be prepared for a long walk! If you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. I made my first scale model on a roll of teletype paper tape (anyone remember that stuff?) On this 1-inch tape, my Sun was the size of the tape - 1 inch in diameter
The Nine Planets Astronomy for Kids
Click on the portal to explore the planets! Yikes! The astronomers have demoted Pluto so there are now only eight planets; Pluto is no longer officially a planet. To create a simpler, more focused atmosphere, I've eliminated the more advanced concepts, emphasized the more basic concepts, and given it more of a 'kid-friendly' look-and-feel
Voyager - The Interstellar Mission
In August 2012, Voyager 1 made the historic entry into interstellar space, the region between stars, filled with material ejected by the death of nearby stars millions of years ago. If the outside particles show a sudden increase and the inside particles a sudden decrease, and these levels hold steady, the spacecraft are closing in on the edge of interstellar space
The highly rarefied region above the chromosphere, called the corona, extends millions of kilometers into space but is visible only during a total solar eclipse (left). (Exactly which bodies should be classified as planets and which as "smaller objects" has been the source of some controversy, but in the end it is really only a matter of definition
Similar in structure and size to Earth, Venus' thick, toxic atmosphere traps heat in a runaway 'greenhouse effect.' The scorched world has temperatures hot enough to melt lead. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons and weather, but its atmosphere is too thin for liquid water to exist for long on the surface
Planet Order from the Sun; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune Our knowledge of our solar system is extensive but it is far from complete. Please visit our Astronomy news section which gives news, notes and general observations, we also have an interactive tour of the solar system (loads in a new window) All planets can be seen with a small telescope or binoculars and private observatories continue to provide useful information
