    Concept of an asteroid redirect mission. Credit: NASA ==================================================================================================================================== The grizzled asteroid miner is a stock character in science fiction. Now, a couple of recent events - one legal and the other technological - have brought asteroid mining a step closer to reality. The legal step was taken when the Senate Commerce, Science and Transportation Committee passed a bill titled H.R. 2262—SPACE Act of 2015. The bill has a number of measures designed to facilitate commercial space development, including a provision that gives individuals or companies ownership of any material that they mine in outer space. According to one estimate,...
  • Photographer Caught Stunning Meteor Instead of Spooky Asteroid

    Hungarian photographer Péter Komka wanted to capture the Halloween asteroid that looked like a skull, as it made its closest approach to Earth. What he got instead was a striking image of a meteor streaking across the sky. Komka set up his camera gear on an equatorial mounted tripod near the medieval castle of Salgó, and took several long exposure shot of the night sky, hoping to get some good enough image of the 2015 TB145 asteroid. Sadly the spooky space rock was too faint and did not appear in his photos. But what he finally captured in one photo...

    Astronomers initially thought the object was an asteroid when they spotted it in early October, and named it Asteroid 2015 TB145. But using the US space agency's Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii, experts "have determined that the celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun," NASA's Jet Propulsion Laboratory said in a statement late Friday. ...

(Don Dixon/Erik Sturkell/University of Gothenburg) It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago. Researchers from the University of Gothenburg uncovered two craters in the county of Jämtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor...

    On Monday, Jupiter took a massive hit from a meteor, which was spotted by amateur astronomers based in the US—and if previous evidence is anything to go by, it could have saved Earth from a massive collision in the process. Dan Peterson of Racine, Wisconsin, was gazing at Jupiter on Monday when he saw a bright, white flash on the surface of the planet. When he posted his observation online, another astrophotographer, George Hall, discovered he'd unknowingly captured the massive explosion on video. Turns out it was probably a meteor striking the surface of the planet—and you can watch the...

    Without warning, a mystery object struck Jupiter on July 19, 2009, leaving a dark bruise the size of the Pacific Ocean. The spot first caught the eye of an amateur astronomer in Australia, and soon, observatories around the world, including NASA’s Hubble Space Telescope, were zeroing in on the unexpected blemish. Astronomers had witnessed this kind of cosmic event before. Similar scars had been left behind during the course of a week in July 1994, when more than 20 pieces of Comet P/Shoemaker-Levy 9 (SL9) plunged into Jupiter’s atmosphere. The 2009 impact occurred during the same week, 15 years later....

    Amateur sightings prompt call for a network of backyard astronomers.On August 20, for the third time in about a year, amateur astronomers spotted a fireball above Jupiter's atmosphere. The discovery suggests the planet gets walloped more often than previously thought, say astronomers, some of whom are calling for a global "volunteer army" of backyard Jupiter watchers. The recent flash follows on the heels of July 2009 and June 2010 fireballs over the gas giant planet. (See "Bright Fireball Slams Into Jupiter" [June 2010] and "Jupiter Impact Creates Huge New Spot" [July 2009].) Astronomers speculate that the August 20 flash was...

    STRANGE ASTEROID: Newly-discovered asteroid 2009 BD is slowly passing by Earth today only 400,000 miles away. The small 10m-wide space rock poses no threat, but it merits attention anyway. The orbit of 2009 BD appears to be almost identical to the orbit of Earth. 2009 BD may be a rare co-orbital asteroid, circling the sun in near-tandem with our planet. Extrapolating the motion of 2009 BD into the future, we see that it remains in the vicinity of Earth for many months to come, never receding farther than 0.1 AU (9.3 million miles) until Nov. 2010.

    NASA has been talking about sending people to Mars by 2035. That goal is still on the books, despite recent upheaval in the space program, according to two of the agency's top scientists. "In the near term, Mars remains our primary focus," Ellen Stofan, NASA's chief scientist said May 15 in a talk at the Royal Institution in London ... ....scientists [also] decided to "redirect" an asteroid into an orbit of the moon and are searching for an asteroid that's an appropriate candidate. "Once we find the right one, we'll use all the technology we've got," he said. "We'll snag...

    Don't worry, NASA's known about it for ages. Like, four whole days. So here’s a fun fact: while you were sleeping last night, you had a near-death experience. Yes, you – and everyone else on this lovely planet. In the wee hours of the morning, a pretty sizeable asteroid soared by the Earth, just missing it. But we’re okay. For now. At 4:13am EDT, asteroid 2014 HL129 essentially side-swiped the Earth, coming within 186,000 miles of our planet. For reference, the moon is 238,855 miles away. Which means the asteroid was much, much closer to us than the moon will...

    Scientists Have Underestimated The Likelihood Of City-Killing Asteroids Hitting Earth Reuters Irene Klotz, Reuters Apr. 28, 2014, 2:59 PM The chance of a city-killing asteroid striking Earth is higher than scientists previously believed, a non-profit group building an asteroid-hunting telescope said on Tuesday. A global network that listens for nuclear weapons detonations detected 26 asteroids that exploded in Earth's atmosphere from 2000 to 2013, data collected by the Comprehensive Nuclear Test Ban Treaty Organization shows. The explosions include the Feb. 15, 2013, impact over Chelyabinsk, Russia, which left more than 1,000 people injured by flying glass and debris. "There is...

One of the first photos showed a large area of flattened trees.Early on the morning of June 30, 1908, a massive explosion shook central Siberia. Witnesses told of a fireball that streaked in from the southeast and then detonated in the sky above the desolate, forested region. At the nearest trading post, about 70 kilometers away from the blast, people were reportedly knocked from their...

    Astronomers may have solved the puzzle of what it was that brought so much devastation to a remote region of Siberia almost a century ago. The asteroid was probably a pile of space rubble - like Mathilde In the early morning of 30 June, 1908, witnesses told of a gigantic explosion and blinding flash. Thousands of square kilometres of trees were burned and flattened. Scientists have always suspected that an incoming comet or asteroid lay behind the event - but no impact crater was ever discovered and no expedition to the area has ever found any large fragments of an ...

    Less than four months after getting switched back on — and only days after its “next light” images — NASA’s re-commissioned NEOWISE mission has made its first discovery: a never-before-seen near-Earth asteroid 27 million miles (43 million km) away. Identified in a series of images captured on Dec. 29, 2013 YP139 is a coal-black asteroid about 650 meters — over 2,100 feet — wide. The image above shows the asteroid as a circled red dot as it moved across NEOWISE’s field of view over a period of several hours. 2013 YP139 would be all but invisible in optical light because...

    Video of Engine Test Using traditional chemical rockets, a trip to Mars – at quickest — lasts 6 months. But a new rocket tested successfully last week could potentially cut down travel time to the Red Planet to just 39 days. The Ad Astra Rocket Company tested a plasma rocket called the VASIMR VX-200 engine, which ran at 201 kilowatts in a vacuum chamber, passing the 200-kilowatt mark for the first time. "It's the most powerful plasma rocket in the world right now," says Franklin Chang-Diaz, former NASA astronaut and CEO of Ad Astra. The company has also signed...

    Monday, January 20, at 10:00 GMT (which is 5:00 a.m. for U.S. East Coasters like me) the wake-up call will ring on ESA’s Rosetta spacecraft, bringing it out of hibernation after over two and a half years in preparation of its upcoming and highly-anticipated rendezvous with a comet. The wake-up will incite the warming of Rosetta’s star trackers, which allow it to determine its orientation in space. Six hours later its thrusters will fire to stop its slow rotation and ensure that its solar arrays are receiving the right amount of sunlight. ... After nearly a decade of soaring through...
  • Astronomy Picture of the Day -- Two Rings for Asteroid Chariklo

    Explanation: Asteroids can have rings. In a surprising discovery announced two weeks ago, the distant asteroid 10199 Chariklo was found to have at least two orbiting rings. Chariklo's diameter of about 250 kilometers makes it the largest of the measured centaur asteroids, but now the smallest known object to have rings. The centaur-class minor planet orbits the Sun between Saturn and Uranus. The above video gives an artist's illustration of how the rings were discovered. As Chariklo passed in 2013 in front of a faint star, unexpected but symmetric dips in the brightness of the star revealed the rings. Planetary...

    Astronomers have nicknamed a new dwarf planet circling the sun at the outer edges of the solar system after Vice President Joe Biden. According to Nature, a leading scientific journal, the object's official designation is 2012 VP113. But the team studying its orbit around the sun colloquially refer to the planet as just "VP" or "Biden," after the sitting vice president. The object won't carry an official title until scientists collect more data. After determining its orbit, they'll submit a formal name to the International Astronomical Union (IAU) for consideration. The Biden dwarf is the second such object to be...
