NASA Astronaut on SpaceX Crew Dragon returns to Earth with successful splashdown!
Moving at about 28,000 kilometers per through temperatures of up to three 500 degrees Fahrenheit spacex crew dragon capsule and also the Astronauts inside safely re-entered earth’s atmosphere on august 2nd.
Welcome back to planet earth and thanks for flying spacex, the globe nervously watched the historic launch the primary from US soil in almost a decade on May 30th 2020.
But it’s this landing that Elon musk most feared here’s what had to travel right so as to bring Bob Benkin and Doug Hurley home. There are two main reasons why reentry is that the most dangerous a part of the mission. Extreme speed and temperature spacex and nasa had to give some thought to these factors in three key ways the primary pain point was finding the precise angle for re-entry, not steep enough the crew dragon would have bounced right off the atmosphere and into orbit, too sharp or too fast and also the astronauts could have faced fatal gravitational forces and also the spacecraft could have caused enough drag to interrupt up
and disintegrate then even at the proper angle moving at about 25 times the speed of sound.
Through the atmosphere creates extreme friction which produces super-heated plasma a protection must deflect and absorb the energy created by the plasma at 3 500 degrees the shield gets hot enough to glow. But Elon Musk said thanks to the Crew dragon’s asymmetric design the craft could have over-rotated during Re-entry and diverted plasma into launch escape pods on the side and if that happened the ship could have Overheated in some parts or started wobbling causing the crew to lose control.
The plasma during reentry caused a six-minute communications blackout between the crew dragon and Ground Com.
Dragon spacex com check so if anything went wrong therein moment device would are impossible. In 2019 auditors listed parachute problems as a key risk to nasa’s commercial crew program and therefore the physics turbulence an area capsule parachute goes through is one amongst the foremost difficult calculations for researchers. Spacex and nasa had to style a totally new system for the crew dragon.
After multiple versions and dozens of tests the mark iii design was approved however musk’s worry was that they could not deploy correctly or that the system would guide the crew dragon to the incorrect splashdown location of these risks were assessed and calculated six ways to Sunday as musk told aviation week but they might never be fully done away with Nasa estimated that there was a 1 in 276 chance of this mission being fatal but both Benkin and Hurley told us they were comfortable with those odds.
Luckily that bet paid off we will officially call this historic mission a hit and spacex is ready to fly the identical crew dragon back to space with four astronauts in spring of 2021.
