When a meteor exploded over Chelyabinsk, Russia on Feb. 15, 2013, many of world's most avid meteorite collectors were gathered on the other side of the world, in Arizona, at the Tucson Gem and Mineral Show.

"A lot of the meteorite guys were scrambling to leave the show early to go to Russia," said Craig Kissick of Heritage Auctions.

This month, Heritage Auctions is selling three pieces of the Chelyabinsk space rock as part of its latest natural history sale.



The meteor blast produced a shockwave that shattered windows and injured more than 1,000 people in Chelyabinsk region.

Scientists who have analyzed samples of the Chelyabinsk meteorite have said it appears to be an ordinary chondrite, the most common type of meteorite found on Earth.

"I wouldn't consider it that attractive," Kissick said, but the fragments have stirred up interest among collectors because they are tied to the biggest meteorite blast in more than a century, and perhaps the most witnessed one on record.

Opening bids for the three Chelyabinsk meteorite fragments start at $500, $2,500 and $4,000. The sale will take place on Sept. 28 at Heritage Auction's Nature and Science Signature Auction in Dallas, Texas.

Major X1.7-Class Solar Flare Erupts from the Sun - Strongest of 2013

The sun unleashed a colossal Mother's Day solar flare on Sunday (May 12) in what has become the most powerful solar eruption of the year.

The giant solar flare, which registered as one of the largest eruptions the sun can unleash, peaked Sunday night at 10:17 p.m. EDT (0217 GMT) and was captured on camera by NASA's Solar Dynamics Observatory.

It sparked an hour-long high-frequency radio blackout, according to the Space Weather Prediction Center (SWPC) overseen by the National Oceanic and Atmospheric Administration (NOAA).

Sunday's solar flare registered as an X1.7-class sun eruption — the strongest type of solar flare the sun can fire off, according to the SWPC officials.

When aimed directly at Earth, X-class solar flares can pose a risk to astronauts and satellites in orbit, as well as interfere with communications and GPS signals on the ground.

They can also super-charge Earth's northern lights displays by bombarding the planet with solar particles, triggering awesome aurora light shows.

Russia to Deorbit ISS Pirs Module in 2013

The ISS currently has five Russian-built modules: the Zvezda service module, the Zarya cargo block, the Pirs docking module, the Poisk ("Search") research module and Rassvet ("Dawn") research module.

Russia plans to deorbit and sink its Pirs docking module of the International Space Station later this year, a high-ranking official with the Russian space corporation RKK Energia said on Friday.

Alexander Kaleri, the head of the company's scientific technical center, said undocking and deorbiting Pirs will take place before a new Russian module docks with the station.

Alexander Derechin, RKK Energia deputy chief designer said in late March the launch of the multirole laboratory module (MLM) is tentatively scheduled for the end of 2013.

"The final spacewalk [by Russian members of the present ISS crew] is scheduled to take place before the arrival of the new multirole laboratory module (MLM) and will be devoted to the "departure" of the Pirs docking module. It should be de-orbited and sunk prior to MLM arrival," he said.

He said that Russian cosmonauts are scheduled to make six spacewalks this year, one of them is currently underway. The six-hour spacewalk by Flight Engineers Pavel Vinogradov and Roman Romanenko is due to end by midnight Moscow time [8:00 p.m. GMT].

Russia is planning to launch four new ISS modules - MLM, a node module and two science-power modules - by 2020, when the time comes to de-orbit the existing international outpost in space.
