4.6 m (15 ft) [1] The European System Providing Refueling Infrastructure and Telecommunications ( ESPRIT) is an under construction module of the Lunar Gateway. [2] It will provide refueling through additional xenon and hydrazine capacity for use in the Power and Propulsion Element 's ion engines and hydrazine thrusters.
The Power and Propulsion Element ( PPE ), previously known as the Asteroid Redirect Vehicle propulsion system, is a planned solar electric ion propulsion module being developed by Maxar Technologies for NASA. It is one of the major components of the Lunar Gateway. The PPE will allow access to the entire lunar surface and a wide range of lunar ...
One Gateway component that had been previously planned for the SLS Block 1B is expected to fly on the Falcon Heavy. [93] [ needs update ] On 1 May 2020, NASA awarded a contract extension to Aerojet Rocketdyne to manufacture 18 additional RS-25 engines with associated services for $1.79 billion, bringing the total RS-25 contract value to almost ...

A gateway is a piece of networking hardware or software used in telecommunications networks that allows data to flow from one discrete network to another. Gateways are distinct from routers or switches in that they communicate using more than one protocol to connect multiple networks [1] [2] and can operate at any of the seven layers of the OSI ...
An application-level gateway ( ALG, also known as application layer gateway, application gateway, application proxy, or application-level proxy) is a security component that augments a firewall or NAT employed in a mobile network. [1] [2] It allows customized NAT traversal filters to be plugged into the gateway to support address and port ...
In 2007, the parameters for Galaxy were again modified, with final specifications being for a spacecraft 4.0 meters (13.1 ft) in length, 3.3 meters (10.8 ft) in diameter and with 16.7 cubic meters (589.8 cu ft) of interior volume—45% greater than the Genesis modules. It was intended for launch in late 2008.
