OrbitalHub

Wikipedia dicit:

A Soyuz spacecraft consists of three parts (from front to back): a spheroid orbital module, which provides accommodation for the crew during their mission; a small aerodynamic reentry module, which returns the crew to Earth; a cylindrical service module with solar panels attached, which contains the instruments and engines.

The orbital and service modules are single-use and are destroyed upon reentry in the atmosphere. Though this might seem wasteful, it reduces the amount of heat shielding required for reentry, saving mass compared to designs containing all of the living space and life support in a single capsule. This allows smaller rockets to launch the spacecraft or can be used to increase the habitable space available to the crew (6.2 m3 or 220 cu ft in Apollo CM vs 7.5 m3 or 260 cu ft in Soyuz) in the mass budget. The orbital and reentry portions are habitable living space, with the service module containing the fuel, main engines and instrumentation.

Soyuz can carry up to three crew members and provide life support for about 30 person days. The life support system provides a nitrogen/oxygen atmosphere at sea level partial pressures. The atmosphere is regenerated through potassium superoxide (KO2) cylinders, which absorb most of the carbon dioxide (CO2) and water produced by the crew and regenerates the oxygen, and lithium hydroxide (LiOH) cylinders which absorb leftover CO2.

The vehicle is protected during launch by a payload fairing, which is jettisoned along with the SAS at ​2 1⁄2 minutes into launch. It has an automatic docking system. The ship can be operated automatically, or by a pilot independently of ground control.

The […] test was conducted using a qualification version of the propulsion system at NASA’s White Sands Test Facility near Las Cruces, New Mexico. While the system never left the ground, it simulated one of the most taxing situations the spacecraft’s engines could encounter after launch.

This test simulated what is referred to as an abort-to-orbit scenario. In the event the interim cryogenic propulsion stage (ICPS) was unable to set the spacecraft on its path to the Moon, Orion would deliberately separate early from the ICPS and the ESA (European Space Agency)-provided service module’s engines would fire to boost the spacecraft into a safe, temporary orbit. That would allow time to evaluate the crew and spacecraft before a decision is made to either continue with an alternate mission profile, or return to Earth. Under an alternate mission profile, Orion and its crew may still be able to accomplish some of the mission objectives even if the trajectory and the primary mission objective has changed.

During the successful test, engineers simulated the abort-to-orbit scenario by firing the Orion main engine on the service module, in addition to all eight of its auxiliary engines simultaneously. Each of the reaction control thrusters were also periodically fired throughout the test to simulate attitude control and overall propulsion system capacity.

Dragon 2 is a reusable spacecraft developed and manufactured by U.S. aerospace manufacturer SpaceX, intended as the successor to the Dragon cargo spacecraft. The spacecraft launches atop a Falcon 9 Block 5 rocket and return via ocean splashdown. In comparison to Dragon, Dragon 2 has larger windows, new flight computers and avionics, redesigned solar arrays, and a modified outer mold line.

The spacecraft is planned to have two variants – Crew Dragon, a human-rated capsule capable of carrying up to seven astronauts, and Cargo Dragon, an updated replacement for the original Dragon. Cargo Dragon capsules are repurposed flown Crew Dragon capsules. Crew Dragon is equipped with an integrated launch escape system in a set of four side-mounted thruster pods with two SuperDraco engines each. Crew Dragon has been contracted to supply the International Space Station (ISS) with crew under the Commercial Crew Program, with the initial award occurring in October 2014 alongside Boeing’s CST-100 Starliner.

During the successful test of Orion’s launch abort system, known as Ascent Abort-2, a camera mounted on a ring connecting the crew module and launch abort system to its booster captured a view of Orion escaping the booster. After the booster separated, its motor continued to burn for several seconds and maintained stability, which allowed for a clear, mid-air view of the Orion elements continuing to execute the abort test. About 27 seconds after the abort is initiated and the Orion elements separate from the booster, the launch abort system’s jettison motor is seen firing, releasing the capsule.

The July 2 test demonstrated the Orion’s launch abort system works during high-stress aerodynamic conditions and can pull the capsule to safety if an emergency ever arises during launch. The test was a critical milestone needed to help pave the way for Artemis missions with astronauts.
