NASA signed a separate contract with Northrop for the fabrication of the HALO, and for integration with the Power and Propulsion Element (PPE), being built by Maxar, for US$935 million. [ 13 ] [ 14 ] In mid 2024, the module reached significant completion and entered into the stress test phase in Thales Alenia 's facilities.
The EUS would then rotate back for Orion to dock with the I-HAB module. Following a successful docking, the EUS would then release the I-HAB module from the payload adaptor along with the Orion spacecraft attached. Orion would then be responsible for delivery of the module to the Lunar Gateway in its near-rectilinear halo orbit. [19]
NASA is supplying the PPE with an S-band communications system to provide a radio link with nearby vehicles and a passive docking adapter to receive the Gateway's future utilization module. [55] NASA awarded a contract of US$331.8 million to launch PPE on a SpaceX Falcon Heavy in 2027 with the HALO module. [44] [56] [1]
It will launch in 2027 pre-attached to the HALO module, for which Thales has separately been awarded a contract by NASA to construct its hull and micrometeoroid protection. The HLCS will measure 2.5 m (8 ft 2 in) in both length and width, have a mass of 270 kg (600 lb), and feature two 125 cm (49 in) dish antennas.
In mid 2024, the HALO module reached significant completion and entered into the stress test phase in Thales Alenia's facilities. Upon successful completion of the stress tests, it is planned to be shipped to the US Northrop Grumman facilities to undergo final launch preparation and integration with the Power and Propulsion Element.

In August 2019, NASA decided to sole source its design for the Minimal Habitation Module (Habitation and Logistics Outpost, or HALO) of the Lunar Gateway to Northrop Grumman Innovation Systems, which offered a minimalist 6.1 m (20 ft) by 3 m (9.8 ft) design based directly on the Enhanced Cygnus, as well as a larger 7 m (23 ft) by 4.4 m (14 ft ...
Orbital replacement units are parts of the main systems and subsystems of the external elements of the ISS. Affecting the control of the cooling system, the movement and control of the solar arrays and SARJ as well as the flow of power throughout the station from solar arrays to the heat rejection system as part of the External Active Thermal Control System (EATCS).
In orbital mechanics a near-rectilinear halo orbit (NRHO) is a halo orbit that passes close to the smaller of two bodies and has nearly stable behavior. [1] The CAPSTONE mission, launched in 2022, is the first spacecraft to use such orbit in cislunar space, and this Moon-centric orbit is planned as a staging area for future lunar missions.
