According to nasa, approximately how many hours is the re-entry descent of a space shuttle after mission control gives the “go” for deorbit burn? hint: o__

Approximately one to one and a half hours.

In an hour and a half, the shuttle should have already fired its reaction control systems thrusters with the vehicle oriented so that it travels upside down and tail first. When everything is ready, mission control issues the “go for de-orbit burn” The de-orbit burn last for 2 ½ minutes. The shuttle’s reaction control systems thrusters rotates the shuttle clockwise, approximately 180 degrees, so it approaches the atmosphere heat shield first, with the nose pitched upwards. At this point, the shuttle is a frying brick with thrusters.

According to NASA re-entry descent of a space shuttle after mission control gives the ‘Go’ for deorbit burn, is approximately one hour. Roughly after 30 minutes of deorbit burn, orbiter (shuttle) faces earth atmosphere around 80 miles above ground surface, and more than 5,000 statute miles from its landing site, called entry interface. At this point orbiter is not fuel by engines instead acts like a free fall object, steered in atmosphere through wings, here spacecraft behaves more like an aircraft. During reentry and landing, after deorbit burn, orbiter’s engine turns off and it flies like high-tech glider, its steering jets helps float in air and then its aerosurfaces to control the airflow around it.
