[Billl] Hill: delivery date for European Service Module for Orion “continues to erode”.
Mr. Hill said it's September and that's "red" (meaning the schedule is not improving).

Hill says Airbus having problems getting vendors to supply components for the service module on time; that’s contributing to overall delay.

Hill: software being delivered on time, but some functionality deferred from one version to the next.

Orion and the European Service Module

Published on Apr 6, 2017

NASA’s Orion spacecraft will take astronauts to destinations at or beyond low Earth orbit. In January 2013, it was announced that ESA would provide the European Service Module (ESM) for Orion’s first uncrewed mission. Derived from ESA’s Automated Transfer Vehicle cargo spacecraft, the ESM will provide life support, propulsion and structural functions for Orion. In February 2017, a contract was signed for a second ESM to be used on Orion’s first crewed flight, which will carry astronauts beyond the Moon and back.
