Columbia Accident Investigation Board
The ''Columbia'' Accident Investigation Board (CAIB) was an internal commission convened by NASA to investigate the destruction of the Space Shuttle ''Columbia'' during STS-107 upon atmospheric re-entry on February 1, 2003. The panel determined that the accident was caused by foam insulation breaking off from the external fuel tank, forming debris which damaged the orbiter's wing, and that the problem of "debris shedding" was well known but considered "acceptable" by management. The panel also recommended changes that should be made to increase the safety of future shuttle flights. The CAIB released its final report on August 26, 2003. Major findings The board found both the immediate physical cause of the accident and also what it called organizational causes. Immediate cause of the accident 82 seconds after launch a large piece of foam insulating material, the "left bipod foam ramp", broke free from the external tank and struck the leading edge of the shuttle's left wing ...

Space Shuttle Solid Rocket Booster
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. A pair of these provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, refurbished, and reused. The Space Shuttle SRBs were the most powerful solid rocket motors to ever launch humans. The Space Launch System (SLS) SRBs, adapted from the shuttle, surpassed it as the most powerful solid rocket motors ever flown, after the launch of the Artemis-1 mission. Each Space Shuttle SRB provided a maximum thrust, roughly double the most powerful single-combustion chamber liquid-propellant rocket engine ever flown, the Rocketdyne F-1. With a combined mass of about , they comprised over half the mass of the Shuttle stack at liftoff. The motor segments of the SRBs were manufactured by ...

Multi-Purpose Crew Vehicle
Orion (officially Orion Multi-Purpose Crew Vehicle or Orion MPCV) is a partially reusable crewed spacecraft used in NASA's Artemis program. The spacecraft consists of a Crew Module (CM) space capsule designed by Lockheed Martin and the European Service Module (ESM) manufactured by Airbus Defence and Space.

It is equipped with solar panels, an automated docking system, and glass cockpit interfaces modeled after those used in the Boeing 787 Dreamliner. A single AJ10 engine provides the spacecraft's primary propulsion, while eight R-4D-11 engines, and six pods of custom reaction control system engines developed by Airbus, provide the spacecraft's secondary propulsion.
