Amateur videos showed a fireball streaking across the sky and a loud boom several minutes afterwards. Local residents witnessed extremely bright burning objects in the sky in Chelyabinsk, Kurgan, Sverdlovsk, Tyumen, and Orenburg Oblasts, the Republic of Bashkortostan, and in neighbouring regions in Kazakhstan, when the asteroid entered the Earth's atmosphere over Russia. The earlier-predicted and well-publicized close approach of a larger asteroid on the same day, the roughly 30 m (100 ft) 367943 Duende, occurred about 16 hours later the very different orbits of the two objects showed they were unrelated to each other.Ĭomparison of possible sizes of the Chelyabinsk (CM mark) and Tunguska meteoroids to the Eiffel Tower and the Empire State Building. The Chelyabinsk meteor is also the only meteor confirmed to have resulted in many injuries. With an estimated initial mass of about 12,000–13,000 tonnes (13,000–14,000 short tons), and measuring about 20 m (66 ft) in diameter, it is the largest known natural object to have entered Earth's atmosphere since the 1908 Tunguska event, which destroyed a wide, remote, forested, and very sparsely populated area of Siberia. Some 7,200 buildings in six cities across the region were damaged by the explosion's shock wave, and authorities scrambled to help repair the structures in sub-freezing temperatures. All of the injuries were due to indirect effects rather than the meteor itself, mainly from broken glass from windows that were blown in when the shock wave arrived, minutes after the superbolide's flash. Its explosion created panic among local residents, and 1,491 people were injured seriously enough to seek medical treatment. The object approached Earth undetected before its atmospheric entry, in part because its radiant (source direction) was close to the Sun. This was 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima. The asteroid had a total kinetic energy before atmospheric impact equivalent to the blast yield of 400–500 kilotons of TNT (about 1.4–1.8 PJ), estimated from infrasound and seismic measurements. Most of the object's energy was absorbed by the atmosphere, creating a large shock wave. The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2 km (16.3 mi 86,000 ft), and many surviving small fragmentary meteorites. The object exploded in a meteor air burst over Chelyabinsk Oblast, at a height of about 29.7 km (18.5 mi 97,000 ft). Some eyewitnesses also reported feeling intense heat from the fireball. It was observed in a wide area of the region and in neighbouring republics. The light from the meteor was briefly brighter than the Sun, visible as far as 100 km (60 mi) away. It was caused by an approximately 18 m (59 ft) diameter, 9,100-tonne (10,000-short-ton) near-Earth asteroid that entered the atmosphere at a shallow 18.3 ± 0.4 degree angle with a speed relative to Earth of 19.16 ± 0.15 kilometres per second (69,000 km/h 42,690 mph). ![]() ![]() The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over the southern Ural region in Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC).

With this in mind, the walkthrough sections below are divided up by the region name and the immediate objective - usually the next upgrade to be found. Although you'll be given an overarching mission when exploring ZDR, a large part of your adventure will be exploring the various regions and finding the next upgrade to your suit - which will expand your exploration and combat abilities. IGN's Metroid Dread Walkthrough is presented by region and objective.
