Asteroid Redirect Crewed Mission Overview

2

Deliver crew on SLS/Orion

Attached Orion to robotic spacecraft

Perform extra-vehicular activity (EVA) to retrieve asteroid samples

Return crew safely with asteroid samples in Orion

NASA Asteroid Initiative Idea Synthesis • #AsteroidCrew

Extravehicular Activity (EVA) Details

• Orion-based EVA with two Crewmembers

• Two EVAs + One Contingency

• Short Duration (~4 hours) in Simple Lightweight Suit

3NASA Asteroid Initiative Idea Synthesis • #AsteroidCrew

Suit and EVA Mission Kits

Four kits were identified to enable Orion Capsule-Based EVA capability

EVA Servicing and Recharge

EVA Tools, Translation Aids & Sample Container

EVA Communications Cabin Repress Kit

Equipment necessary for multiple EVAs including recharge for PLSS water and oxygen, crew equipment, etc.

Standard and specialized tools to complete mission objectives

Repackaged Primary Life Support System radio that allows communication between EVA crew and ground

Provides enriched air for multiple repressurizations of the cabin without using Orion resources

Leverage current ISS and Apollo experience.

Based on ISS Nitrogen/Oxygen Recharge Concept

Based on ISS and Shuttle equipment

Utilizes common radio currently being developed by Advanced Exploration Systems 4

Asteroid Redirect Mission builds upon Orion/SLS to enable Global Exploration Roadmap

RFI Selection Process

• Our panel of experts carefully reviewed 22 RFI’s in the area of Crew Systems and Extensibility.

• Proposals were selected based on:– Merit for the mission;– Extensibility towards next missions (Lunar, Deep Space, and

towards Mars)– Design maturity;– Applicability towards mission guidelines

• Consolidated into 13 presentation/discussions representing a industry, NASA, international, and academia.
