0.3 kilotonnes of TNT (1.3 TJ) 16–24 km (10–15 mi) An airburst detected in El Paso and Las Cruces. The fireball traveled S-SE before disintegrating 10–15 miles above the surface with a loud explosion, traveling around 30,000 MPH. Luminosity is described only as "a very bright flash of light, bright orange-red, similar to a distant sunset".
Took over the ARP/BRSCC Formula 3 Cup in 2011, before folding in 2020. Was run by the Monoposto Racing Club in 2021 before being integrated into their series. Formula Lites: United States: 2015 Formula Renault Eurocup: Europe: 2019–2020 The series utilized Formula 3 chassis for the first time and new 1.8-litre turbocharged engine in 2019.
A meteorite is a portion of a meteoroid or asteroid that survives its passage through the atmosphere and hits the ground without being destroyed. [22] Meteorites are sometimes, but not always, found in association with hypervelocity impact craters; during energetic collisions, the entire impactor may be vaporized, leaving no meteorites.
Harvard researchers found that when a meteorite nicknamed S2 paid a visit to our planet 3 billion years ago, it may have helped life flourish.
In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2] The vehicle, however, burned on atmospheric re-entry, and only charred remnants were found. In April 1961, Russian Major Yuri Gagarin became the first human to travel at hypersonic speed, during the world's first piloted orbital flight.
An approximate rule of thumb for shock wave standoff distance is 0.14 times the nose radius. One can estimate the time of travel for a gas molecule from the shock wave to the stagnation point by assuming a free stream velocity of 7.8 km/s and a nose radius of 1 meter, i.e., time of travel is about 18 microseconds.
Uncovering ancient impacts. Early in Earth’s history, space rocks frequently hit the young planet. It is estimated that “giant impactors,” greater than 6.2 miles (10 kilometers) across ...
NASA says four radar sweeps detected “signatures consistent with falling meteorites seen at the time and location reported by eyewitnesses,” and people also heard sonic booms. Museum offers ...
