Soyuz MS-16 cuts off its engine, completing the deorbiting maneuver that puts it on its way into the atmosphere...

Deorbit Burn complete. Soyuz MS-16 fired retrograde for 5 mins and 20 seconds, shaving off 128 meter per second, enough to force Soyuz to drop out of orbit.

Three humans heading home.

Module separation has occurred, Mission Control reports.

The three segments of the Soyuz MS-16 spacecraft have jettisoned apart, allowing the crew-carrying Descent Module to safely ferry the three crew members back to Earth. The no-longer-needed Orbital Module and Instrumentation/Propulsion Module are designed to burn up in the atmosphere.

Descent module of #SoyuzMS16 entered dense atmosphere; the parachute system release will be initiated in around 8.5 minutes at an altitude of 10 kilometers above ground at 05:40:21 Moscow (10:40 p.m. EDT)

Entry Interface. The Soyuz is now hitting the upper fringes of the atmosphere at an altitude of around 326,000 feet, flying at an angle of 1.35 degrees. The Expedition 63 crew will soon begin to feel the first tugs of Earth's gravity after spending more than six months in space.

The entry guidance by the spacecraft's onboard software package is scheduled to start in a few minutes.

The Soyuz is aiming for a touchdown target at 47.31 degrees north latitude and 69.56 degrees east longitude on the steppe of Kazakhstan.

Russian recovery forces are on station at the landing site for the arrival of the Soyuz MS-16 spacecraft.
It is about 45 deg F (7 deg C) and sunny at the landing site.

The crew experiences the period of maximum g-forces at this point during entry, as the Soyuz exits the sheath of plasma that surrounded it during the hottest part of the descent.

On-board computers should be starting a commanded sequence for deployment of the capsule's parachutes at an altitude of about 10 kilometers, or 6 miles. Two "pilot" parachutes are unfurled first, extracting a 24-square-meter drogue parachute. Within 16 seconds, the craft's fall will slow from 230 meters per second to about 80 meters per second.

The parachute deployment creates a gentle spin for the Soyuz as it dangles underneath the drogue chute, assisting in the capsule's stability in the final minutes before touchdown.
