The stairs are often built into a clamshell-style door on the aircraft. 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.
] This was the last static fire conducted at the now-demolished Suborbital Pad B, [8] as future tests will use the static fire stand at Massey's Test Site. [9] Booster 12 moved to the launch pad on July 9. [10] The booster performed a spin prime test on July 12; it was the first time a spin prime test was performed since Booster 9 in August ...
HLS features landing legs, a body-mounted solar array, [45] a set of thrusters mounted mid-body to assist with final landing and takeoff, [45] two airlocks, [44] and an elevator to lower crew and cargo onto the lunar surface. [46] In 2021, Musk said that between "four and eight" tanker launches would be required to fully fuel HLS. [47]
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 ...
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 ...
v. t. e. A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable ...
Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Space Force Base, California, U.S. It has two pads, both of which are used by SpaceX for Falcon 9, one for launch operations, and the other as Landing Zone 4 (LZ-4) for SpaceX landings. The complex was previously used by Atlas and Titan rockets between 1963 and 2005.
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 ...
