Ballistic Descent

Ballistic Descent

 

the descent in the atmosphere of a flying spacecraft that possesses a zero lift-drag ratio. The trajectory of the ballistic descent is calculated beforehand for the given characteristics of a flying spacecraft and the parameters of the atmosphere that are known with definite accuracy; based on this trajectory, a choice is made of the place and angle of entry into the atmosphere for the flying spacecraft that ensures its landing in the prescribed area of the planet’s surface.

That was not the case for Soyuz, as it was forced to return to the Earth in a ballistic descent.
Ballistic descent uses the atmospheric drag to slow down the spacecraft - in other words, the atmospheric air resistance pushes up against the falling rocket.
The Soyuz booster aborted after its launch, after which the crew switched to the mode of a ballistic descent. The manned Soyuz MS-10 spacecraft landed in the Kazakh steppe.
The capsule jettisoned from the booster and went into a ballistic descent, landing at a sharper than normal angle and subjecting the crew to heavy G-forces.
Parachutes were eventually deployed as their capsule went into a "ballistic descent", landing at a much sharper than normal angle, according to Nasa.
The Soyuz capsule returned to Earth via a ballistic descent, which is a sharper angle of landing compared to normal.
The Soyuz capsule is returning to Earth via a ballistic descent, which is a sharper angle of landing compared to normal.
Summary: Moscow [Russia], October 11 (Sputnik/ANI): A carrier failure occurred during the launch of the Russian Soyuz MS-10 manned spacecraft from the Baikonur space center to the International Space Station (ISS) on Thursday, which made the capsule with the crew return to Earth in a ballistic descent mode.
The men were forced into a "ballistic descent", with their capsule landing a few hundred miles north of Baikonur.
A computer software error probably sent a Russian spacecraft into a rare ballistic descent that subjected the three men on board to chest-crushing gravity loads that made it hard to breathe, space experts said yesterday.
Eleven minutes later, it added, "The crew is returning to Earth in a ballistic descent mode," meaning that it was falling without propulsion and that its direction was determined only by the craft's momentum.
