Dynetics Human Landing System
The Dynetics Autonomous Logistics Platform for All-Moon Cargo Access (ALPACA)—also known as Dynetics HLS—(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 contractors included Sierra Nevada Corporation—for NASA's Artemis Program. The lander concept was initiated in 2019, and in April 2020, Dynetics won a contract from NASA for a year-long design concept study to be completed in early 2021. NASA had intended to subsequently issue build and test contracts to one or two of the three 2020 awardees in order to advance the human landing element of the Artemis Program. In the event, the Dynetics HLS proposal was not selected by NASA in April 2021, and a sole HLS award was won by SpaceX with the Starship HLS proposal. However, Dynetics, together with Blue Origin, protested this decision with the GAO through the S. 12 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SpaceX Starship
Starship is a Fully-reusable orbital launch vehicle, fully reusable, super heavy-lift launch vehicle under development by SpaceX, an American aerospace company. With more than twice the thrust of the Saturn V, it is designed to be the most powerful launch vehicle ever built and the first with total reusability. The Starship launch vehicle is made up of the SpaceX Starship#Super Heavy booster, Super Heavy first-stage booster and the SpaceX Starship#Starship spacecraft, Starship second stage. The second stage functions as a self-contained spacecraft for carrying crew or cargo once in orbit. Both stages are powered by Raptor engines that burn liquid oxygen and liquid methane propellants in a highly efficient, full-flow staged combustion power cycle. Both rocket stages are designed to be reused by landing vertically at the launch pad or at a separate platform. In its fully reusable configuration, Starship has a payload capacity of to low Earth orbit and is designed to be flown mul ...

Exploration Upper Stage
The Exploration Upper Stage (EUS) is being developed as a large second stage for Block 1B and Block 2 of the Space Launch System (SLS), succeeding Block 1's Interim Cryogenic Propulsion Stage. It will be powered by four RL10C-3 engines burning liquid oxygen and liquid hydrogen to produce a total thrust of . , the SLS Block 1B will have a payload capacity to low Earth orbit of and Block 2 will have a payload capacity of . The EUS is expected to first fly on Artemis IV in March 2026. Development The Block 1 configuration of SLS has a core stage powered by four RS-25 engines, two Space Shuttle-derived five-segment solid rocket boosters, and an Interim Cryogenic Propulsion Stage (ICPS) upper stage. NASA will develop the EUS to increase SLS performance beyond Block 1 specifications. The improved upper stage was originally named the Dual Use Upper Stage (DUUS, pronounced "duce") but was later renamed the Exploration Upper Stage (EUS) due to DUUS sounding lik ...

Space Launch System
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle developed by NASA. As of 2022, SLS has the highest payload capacity of any rocket in operational service, as well as the greatest liftoff thrust of any rocket in operation. As the primary launch vehicle of the Artemis moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first uncrewed launch, Artemis 1, took place on 16 November 2022. Development of SLS began in 2011, as a replacement for the retired Space Shuttle as well as the cancelled Ares I and Ares V launch vehicles. As a Shuttle-derived vehicle, the Space Launch System reuses hardware from the Space Shuttle program, including the Space Shuttle Solid Rocket Booster, solid rocket boosters and RS-25, RS-25 first stage engines. An original flight date of late 2016 was delayed by nearly 6 years. The SLS program has Space Launch System#Criticism, attracted criticism for such de ...

Centaur (rocket Stage)
The Centaur is a family of rocket propelled upper stages produced by U.S. launch service provider United Launch Alliance, with one main active version and one version under development. The diameter Common Centaur/Centaur III flies as the upper stage of the Atlas V launch vehicle, and the diameter Centaur V is being developed as the upper stage of ULA's new Vulcan rocket. Centaur was the first rocket stage to use liquid hydrogen (LH2) and liquid oxygen (LOX) propellants, a high-energy combination that is ideal for upper stages but has significant handling difficulties. Characteristics Common Centaur is built around stainless steel pressure stabilized balloon propellant tanks with thick walls. It can lift payloads of up to . The thin walls minimize the mass of the tanks, maximizing the stage's overall performance. A common bulkhead separates the LOX and LH2 tanks, further reducing the tank mass. It is made of two stainless steel skins separated by a fiberglass honeycomb. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near-rectilinear Halo Orbit
A near-rectilinear halo orbit (NRHO) is a halo orbit with slightly curved – or nearly straight – sides between close passes with an orbiting body. The 2022 CAPSTONE mission is the first such orbit in cislunar space, and this Moon-centric orbit will serve as a staging area for future lunar missions. The orbit could be used with other bodies in the Solar System and beyond. A halo orbit is a periodic, three-dimensional orbit associated with one of the L1, L2 and L3 Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an elliptical orbit of the same maximum diameter, and other segments have a curvature less than that of an elliptical orbit of the same maximum diameter (taking maximum diameter as that of the smallest circle that contains the whole of the orbit). In the extreme case all segments have zero curvature with four points with infinite curvature (''i.e.'' a polygon). Such a non-elliptical orbit would require at lea ...

Vulcan Centaur
Vulcan Centaur is a two-stage-to-orbit, heavy-lift launch vehicle that is under development by the United Launch Alliance (ULA) since 2014 with an initial flight expected in early 2023. It is principally designed to meet launch demands for the U.S. government's National Security Space Launch (NSSL) program for use by the United States Space Force and U.S. intelligence agencies for national security satellite launches. The maiden flight is slated to launch Astrobotic Technology's ''Peregrine'' lunar lander for NASA's Commercial Lunar Payload Services (CLPS) program and Kuiper Systems' Kuipersat-1 and Kuipersat-2, no earlier than 2023, after multiple delays from the initially planned first flight in 2019. Description Vulcan is ULA's first new launch vehicle design; it adapts and evolves technologies that were developed for the Atlas V and Delta IV rockets of the USAF's EELV program. The first-stage propellant tanks have the same diameter as the Delta IV Common Booster Core ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airlock
An airlock, air-lock or air lock, often abbreviated to just lock, is a compartment with doors which can be sealed against pressure which permits the passage of people and objects between environments of differing pressure or atmospheric composition while minimizing the change of pressure in the adjoining spaces and mixing of environments. The lock consists of a relatively small chamber with two airtight doors in series which do not open simultaneously. An airlock may be used for passage between environments of different gases or different pressures, or both, to minimize pressure loss or prevent the gases from mixing. An airlock may also be used underwater to allow passage between an air environment in a pressure vessel and the water environment outside, in which case the airlock can contain air or water. This is called a floodable airlock or an underwater airlock, and is used to prevent water from entering a submersible vessel or an underwater habitat. Air-locks are used in ...
