Spacecraft flight dynamics. Spacecraft flight dynamics is the application of mechanical dynamics to model how the external forces acting on a space vehicle or spacecraft determine its flight path. These forces are primarily of three types: propulsive force provided by the vehicle's engines; gravitational force exerted by the Earth and other ...
Airstairs eliminate the need for passengers to use a mobile stairway or jetway to board or exit the aircraft, providing more independence from ground services. Some of the earliest aircraft to feature airstairs were the Martin 2-0-2 and Martin 4-0-4. Some models of the Douglas DC-3 were also retrofitted with airstairs (see picture).
t. e. SpaceX has privately funded the development of orbital launch systems that can be reused many times, similar to the reusability of aircraft. SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage ...

Dynetics HLS. The Dynetics Autonomous Logistics Platform for All-Moon Cargo Access (ALPACA)—also known as Dynetics HLS[1] — (ILV) is a human spaceflight lunar lander design concept proposed in 2020/21 for the NASA Human Landing System (HLS) component of the Artemis program. Dynetics was the lead contractor for the ALPACA lander—other ...
Commercial Lunar Payload Services (CLPS) is a NASA program to hire companies to send small robotic landers and rovers to the Moon. Most landing sites are near the lunar south pole [1][2] where they will scout for lunar resources, test in situ resource utilization (ISRU) concepts, and perform lunar science to support the Artemis lunar program.
Krechet-94 Suit. The Krechet-94 (Russian Кречет, meaning gyrfalcon) is a space suit model developed for lunar excursion during the Soviet crewed lunar program. It was designed by NPP Zvezda. Development began in 1967, concurrently with the Orlan suit for microgravity spacewalks. The developmental model was known simply as Krechet.
The Handicare 1100 Straight Stairlift is perfect for narrow stairs, given its 12.6 inches width when folded. This can be a game-changer for homes with limited stair space, providing a practical ...
