2. Discussionof: • UPC-Orion History • UPC-Orion Vision • UPC Accommodation Information Depart the meeting with a clear understanding of the UPC-ORION Concept.

3. History of “Exploration Carriers” • NASA Administrator directed accommodation of ISS-bound UnPressurized Cargo (UPC) to meet resupply needs after STS retirement (aka, ORUs) • Constellation Program Level-2 requirements presented at Program SRR and recommended that Orion provide a… • Smart Service Module capability • Robust UPC capability supporting • Orbital Replacement Units • “Smart” Payload Class • Requirements sanctioned and initially assigned to Orion/Level-3 • ESMD assigned implementation role to GSFC on 10/30/07, leveraging the center’s 20+ year “Hitchhiker” legacy • ISS-bound Missions: • Mass (est.): m > 590 kg • Power (est.): P > 100 W avg., P > 1.3kW-peak • TLM (est.): r > 1 Mbps • Lunar-bound Missions: • Mass (est.): m > 80 kg • Power (est.): P > 200 W avg., P > TBD W-peak • TLM (est.): r > 2 Mbps

4. Vision for “Exploration Carriers” • OPS Concept: a “one stop shop” where users come to obtain access to space via the Constellation architecture using a plug-n-play interface and established programmatic interfaces • Leverages the efficiencies validated during the Attached Payloads era • Reduces Technical and Programmatic risk • Exploration Carriers manage the Orion-Carrier Interface…not the users • Safety, Integration, Mission Operations interfaces established and validated • The Exploration Carriers concept provide to the Agency what the “SIM Bay” provided to Apollo, and Hitchhiker provided to the Space Shuttle • Rapid access to space for secondary payloads • Concept “scaleable” to all Exploration Mission Phases (i.e., ISS, Moon, Mars) • Offers a unique opportunity for long-term collaboration Exploration Carriers will be…an Orion- or Altair-attached carrier offering standardized H/W, command, and telemetry interfaces and providing rapid access to space for unpressurized cargo to ISS, the moon, and beyond…

5. Orion Service Module Design Trades • Studies to evaluate positioning of UPC for ISS missions complete • GSFC is beginning efforts to bring definition up to PDR-level maturity • Require SMD-focused studies for bounding user cases

Constellation’s Orion Service ModuleScience Payload Unpressurized Carrier Potential Capabilities ACCOMMODATIONS • Fixed Payloads on Orion’s Service Module (SM) • Test Equipment and Instrumentation (e.g. sensors/detectors, cameras) • Further characterize the in-situ/flight environment • Short flight duration • Payload destroyed upon SM reentry to Earth’s atmosphere • Externally Attached Payloads on International Space Station • Conduct science investigations and/or demonstrate technology • External facility sites include JAXA’s JEM-EF, ESA’s Columbus, U.S. Express Logistics Carrier • Long flight duration • Potential payload return to Earth • Deployable Payloads • Aboard Orion/SM for insertion into LEO, translunar, cis-lunar or other compatible trajectories • Possible long duration orbits with payload propulsion package Contacts: Bruce Milam 301-286-0429 Bruce.Milam@nasa.gov; Ruthan Lewis 301-286-0818 ruthan.lewis@nasa.gov 4/08
