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.
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform. SpaceX developed these vessels to recover the first stage (also called the booster) of its launch vehicles. By recovering and reusing these boosters, SpaceX has significantly ...
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 to the ...
Several missions of Falcon 9 v1.1 were followed by post-mission test flights calling for the first-stage booster to execute a flip around maneuver, a boostback burn to reduce the rocket's horizontal velocity, a re-entry burn to mitigate atmospheric damage at hypersonic speed, a controlled atmospheric descent with autonomous guidance to the ...
A woman living in an upstairs apartment said that she hardly sees anyone coming to the building to work. Plainclothes police arrived on site when CNN was there.
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 ...
A floating launch vehicle operations platform is a marine vessel used for launch or landing operations of an orbital launch vehicle by a launch service provider: putting satellites into orbit around Earth or another celestial body, or recovering first-stage boosters from orbital-class flights by making a propulsive landing on the platform.
Shuttle-era Astrovan at Launch Pad 39A. The astronaut transfer van, known as the Astrovan during the Space Shuttle era, was a NASA vehicle used at the Kennedy Space Center to transport astronauts from the Operations and Checkout Building to the launch pad before a mission and for launch dress rehearsals, and back to the Operations and Checkout Building following a shuttle landing.
