The #Soyuz will encounter 'Entry Interface' at 08:15:06 GMT. The 'g-force' will begin to build and it will get 'sporty' inside, with vibration, noise, and heat. Entry Interface occurs at an altitude of 99.6 km / 61.8 miles, at a speed we affectionately call 'the speed of heat'!💫 pic.twitter.com/DQ6Qh2Au9r
