the aft liquid hydrogen (LH 2) tank; this was the largest part, but it was relatively light, due to liquid hydrogen's very low density. The ET was the "backbone" of the shuttle during launch, providing structural support for attachment with the Space Shuttle Solid Rocket Boosters (SRBs) and orbiter. The tank was connected to each SRB at one ...
The solar cells/panels can be placed in direct contact with the electrolyzer(s), which can bring advantages in terms of system compactness and thermal management of both technologies, [32] or separately for instance by placing the PV outdoors exposed to sunlight and the EC systems protected indoors.
ET absorption of medications is poor, and optimal ET drug dosings are unknown. IO administration is becoming more common in civilian and military pre-hospital emergency medical services (EMS) systems globally. [11] Intraosseous access has roughly the same absorption rate as IV access, and allows for fluid resuscitation.
The integral fast reactor (IFR), originally the advanced liquid-metal reactor (ALMR), is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor). IFRs can breed more fuel and are distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site.
The main propulsion system works to reduce the risk of fire in the engine section: while staged for work and servicing, the engine section is purged with clean air; on the launch pad, during flight preparations, the space is filled with nitrogen gas supplied from ground support equipment to mitigate the buildup of hazardous gases like hydrogen ...

This testing allowed the Exploration Ground Systems (EGS) team to verify access to several servicing panels on the Orion vehicle, which will be needed to prepare Orion for Artemis 1. December 14, 2018 – Successful countdown demonstration completed, intended to validate the launch team's capability to perform an Artemis 1 countdown and respond ...
