    A 400 kilometre-wide impact zone from a huge meteorite that broke in two moments before it slammed into the Earth has been found in Central Australia. The crater from the impact millions of years ago has long disappeared. But a team of geophysicists has found the twin scars of the impacts – the largest impact zone ever found on Earth – hidden deep in the earth’s crust. Lead researcher Dr Andrew Glikson from the ANU School of Archaeology and Anthropology said the impact zone was discovered during drilling as part of geothermal research, in an area near the borders of...

    CAPE CANAVERAL, Fla. (AP) — A newly discovered asteroid will pass by Earth this weekend. At closest approach Sunday, the 60-foot rock will pass a safe 25,000 miles over New Zealand. That’s about one-tenth the distance between here and the moon. It’s also beyond the orbit of our highest communication and weather satellites.
  • An asteroid will just miss Earth today. We won't always be so lucky

    On Sunday afternoon — at 2:15 pm Eastern time, to be exact — a small asteroid will whiz by the Earth. Don't worry: it'll miss us by about 25,000 miles. To be clear, there is zero chance it can hit us. This is certain. But in the long-term, worrying a little about asteroids isn't an unreasonable idea. Now, the odds of a massively destructive asteroid impact at any given time are tiny — but the potential costs would be enormous. Yet we still haven't invested in all the infrastructure needed to spot small asteroids with much warning (we spotted this...

    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...

    Scientists have made a stunning discovery in the outer realm of the solar system — an asteroid with its own set of rings that orbits the sun between Saturn and Uranus. The space rock is the first non-planetary object ever found to have its own ring system, researchers say. The pair of space rock rings encircle the asteroid Chariklo. They were most likely formed after a collision scattered debris around the asteroid, according to a new study unveiled today (March 27). The asteroid rings also suggests the presence of a still-undiscovered moon around Chariklo that's keeping them stable, researchers said....

    This is a rare opportunity to witness an asteroid pass in front of a bright star, blocking out its light for up to ~14 seconds. Occultations occur all the time, but rarely do they happen to stars that are this bright and easy to see by naked eye. In that sense, it is likely a once in a lifetime event for those living near the path of occultation. Regulus is the brightest star in the constellation Leo and the 22nd brightest star in the night sky overall. The occultation will occur at about 2 am tomorrow morning. The path takes...

    Many of the primitive bodies wandering the asteroid belt between Mars and Jupiter are former comets, tossed out of orbit by a brutal ballet between the giant outer planets, said a team of astrophysicists. A commonly accepted theory is that the asteroid belt is the rubble left over from a "proto-planetary disk," the dense ring of gas that surrounds a new-born star. But the orbiting rocks have long been a source of deep curiosity. They are remarkably varied, ranging from mixtures of ice and rock to igneous rocks, which implies they have jumbled origins. The answer to the mystery, according...

    Asteroid Medley Challenges Naturalistic Origins by Brian Thomas, M.S. * Data from recent spacecraft flybys challenge the prevailing naturalistic perspective on asteroid origins. Secular astronomers assume that natural processes, rather than miracles, created the sun, Earth, planets, and asteroids from ancient, swirling masses of gases, but this new evidence points to something different. Writing in the British science journal Nature, Harvard's Francesca DeMeo and the Paris Observatory's Benoit Carry summarized the latest asteroid puzzles.1 For decades, secularists argued that asteroids somehow formed from merging dust particles in a hot nebula. Thus, where they orbit and what they're made of should...

    The microwave discharge ion engines onboard HAYABUSA asteroid explorer have marked space operation of twenty thousands hour and unit as the accumulated operational time on December 9th. HAYABUSA spacecraft, which was launched on May 2003, succeeded the Earth swing-by on May this year and continues to transfer into the asteroid using the acceleration by the ion engines. They generated 1,300m/s delta-V consuming 20kg propellant up to now. After September the space maneuver using three ion engines was throttled down in order to adapt power reduction of the solar array panels due to enlargement of solar distance. Furthermore one of three...

    Slowly pulling alongside a space rock the size of several typical city blocks, a Japanese probe is preparing to begin scooping the first dusty samples of material from the surface of an asteroid this fall for an eventual return to Earth. Japan's Hayabusa spacecraft is halfway through a four-year $100 million mission to chase down a small celestial target, retrieve pieces of its rocky crust, and return them safely to Earth in a capsule designed to survive the intense heat as it enters the atmosphere and parachutes to a safe landing. Formerly known as MUSES-C, the Hayabusa craft was launched...

    England - Rivals from the United States and Europe get the bigger headlines and bigger budgets, but a little-noticed Japanese mission to a distant space rock may scoop them all. Launched on May 9 2003, the little probe Hayabusa ("Falcon") is now on the brink of rendezvousing with a 630-metre asteroid on a mission that could prove historic. If all goes well, Hayabusa will be the first spacecraft to bring home raw material from an asteroid, part of the primeval rubble left over from the making of the Solar System. "It is an utterly remarkable project which has been given...

    Smash-and-grab expected to be breakthrough 'Glitterball' with 877,490 names to be left behind Under the gentle puff of its ion drive, a Japanese space probe is positioning itself for an extraterrestrial first: a smash and grab on a speeding asteroid. The Hayabusa (or falcon) probe has been chasing the asteroid since 2003 and has this week reached within tens of miles of its surface.Scientists at the Japanese Institute of Space and Astronautical Science will spend the next few weeks using Hayabusa's cameras to build up a detailed map of the asteroid. The probe will close in on the asteroid...
  • Japanese Asteroid Sample-return Spacecraft HAYABUSA Arrives [at] Itokawa

    Japanese asteroid sample-return spacecraft Hayabusa arrived Itokawa on 10:00 am, 12 Sep (JST: Japanese Standard Time). Now Hayabusa hovers around 20 kilometers away from asteroid Itokawa. Hayabusa will bring back samples from an asteroid and investigate the mysteries of the birth of the solar system. This picture was taken at 8:35 am, 12 Sep (JST) just before the settlement by the visible imager AMICA. Field of view is two degrees. The photo shows contrast of rocky and hilly region and smooth area, which may suggest the origin of this asteroid. This feature may be a key to consider Itokawa’s origin...

    PARIS — Japan’s Hayabusa asteroid sample-return spacecraft has lost the use of a second reaction wheel, forcing increased reliance on its chemical-propellant thrusters for attitude control and raising questions about whether it can make its planned asteroid touchdown in November, Japan’s Institute of Space and Astronautical Science (ISAS) announced Oct. 4. Hayabusa, known as MUSES-C before its May 2003 launch, remains in a stable position 6.8 kilometers from its target, the Itokawa asteroid, now 305.9 million kilometers from Earth. Using two reaction control systems with the remaining reaction wheel, the probe is scheduled to continue scouting possible landing sites on...

    23:39 2005-11-12 A landing craft from the Japanese space probe Hayabusa is expected to land on Itokawa as part of the first ever mission to land on an asteroid. The names of people from Liverpool are among about a million gathered globally which have been inscribed on an aluminium sheet on a landing robot. It is thought the names will lie on the asteroid for about one billion years. They were gathered by the Planetary Society of Japan as part of the mission, which aims to gather samples of space dust, reports BBC News. According to, taking some 12...

    TOKYO (AP) -- A Japanese spacecraft showed signs of trouble Saturday after apparently landing on an asteroid and collecting surface samples in an unprecedented mission to bring the extraterrestrial material back to Earth, officials said. The Hayabusa probe, hovering about three miles from the asteroid, appeared to be shaking due to a possible gas leak from a thruster, said Atsushi Akoh, a spokesman for Japan's space agency, JAXA. JAXA will put Hayabusa into "safety mode" - which stabilizes the probe by turning its solar panels toward the sun - for two to three days to investigate, Akoh said. Communications between...

    TOKYO - A Japanese spacecraft on an unprecedented mission to bring asteroid material back to Earth is set to start home despite showing signs of trouble earlier, an executive of Japan's space agency, JAXA, said Sunday. On Saturday, the Hayabusa probe apparently landed on the Itokawa asteroid and collected surface samples. After the landing, the probe hovered about three miles from the asteroid and appeared to be shaking due to a possible gas leak from a thruster, JAXA said. The probe shut down all its engines Saturday and switched to solar power while JAXA investigated the problem. But the probe...

    A Japanese space probe which scientists hope will bring back a sample from an asteroid is due to return to Earth on schedule late on Sunday in the Australian outback, an Australian defense official said. The Hayabusa probe is due to land around 11.30 p.m. (1400 GMT) near the Woomera military range in the remote desert north of South Australia state. [snip] The return will mark the end of a seven-year journey that has taken the probe to the near-Earth asteroid Itokawa and back. It landed on the asteroid twice in 2005 and scientists hope it may have captured a...

    Explanation: Where are the craters on asteroid Itokawa? Missing -- unexpectedly. The Japanese robot probe Hayabusa approached the Earth-crossing asteroid in 2005 and returned pictures showing a surface unlike any other Solar System body yet photographed -- a surface possibly devoid of craters. The leading hypothesis for the lack of common circular indentations is that asteroid Itokawa is a rubble pile -- a bunch of rocks and ice chunks only loosely held together by a small amount of gravity. If so, craters might not form so easily -- or be filled in whenever the asteroid gets jiggled by a passing...
