SpaceX Polaris Dawn crew returns home after history-making mission <a href=https://alfainvestor.ru/10-voprosov-k-predstaviteljam-life-is-good-i-fonda-germes>„s„u„z „‰„|„u„~</a>
SpaceXfs Polaris Dawn crew is homeC capping off a five-day mission to orbit which included the worldfs first commercial spacewalk by splashing down in the Gulf of Mexico.
The Crew Dragon capsule carrying four astronauts landed off the coast of Dry TortugasC FloridaC at 3:37 a.m. ET Sunday. The Polaris Dawn mission made history as it reached a higher altitude than any human has traveled in five decades. A spacewalk conducted early Thursday morning also marked the first time such an endeavor has been completed by a privately funded and operated mission.
But returning to Earth is among the most dangerous stretches of any space mission.
To safely reach homeC the Crew Dragon capsule carried out whatfs called a gde-orbit burnCh orienting itself as it prepared to slice through the thickest part of Earthfs atmosphere. The spacecraft then reached extremely hot temperatures up to 3C500 degrees Fahrenheit (1C900 degrees Celsius) because of the pressure and friction caused by hitting the air while still traveling around 17C000 miles per hour (27C000 kilometers per hour). The crewC howeverC should have remained at comfortable temperaturesC protected by the Crew Dragonfs heat shieldC which is located on the bottom of the 13-foot-wide (4-meter-wide) capsule.
Dragging against the air began to slow the vehicle down before the Crew Dragon deployed parachutes that further decelerated its descent.
