Robotic precursor mission to return material samples from Mars ! 70-t SLS could support one-launch Mars Sample return mission with sampling rover carrying ascent vehicle and in-space return vehicle ! SLS could support two-flight sample return in conjunction with 2020 Mars science rover mission, launching ascent vehicle and in-space return vehicle 8602_Mars Society_T.May.12 Case Study: Martian Moons ! Provides stepping-stone opportunity toward human landing on Mars ! Allows for real-time human-robotic telepresence exploration of Martian surface ! Provides ambitious Mars-vicinity target while developing Martian EDL capability ! SLS offers mass and volume capability for needed habitation and propulsion systems 8602_Mars Society_T.May.13 Case Study: NASA DRA5 ! NASA’s 2009 Design Reference Architecture 5 outlines plan for 900-day human mission to Mars. ! DRA5 requires 825 metric tons initial mass to low Earth orbit (almost double ISS launch mass). ! SLS exceeds DRA5 minimum 125+ t to LEO mass launch requirement and meets DRA5 minimum 10-m-diameter fairing requirement. 8602_Mars Society_T.May.14 July 2009 Recent Progress Launch Vehicle Stage Adapter: Contract MPCV-to-Stage Adapter: awarded in February 2014. First flight hardware currently in Florida for Exploration Flight Test-1 in Fall 2014. Avionics: Avionics “first light” marked in January 2014; currently testing most powerful flight system computer processor ever. Core Stage: Initial confidence barrels and domes completed; Vertical Assembly Center installation to be completed in July 2014. Boosters: Forward Skirt test completed May 2014; preparations underway for QM-1. Engines: First RS-25 engine fitted to A-1 stand at Stennis Space Center; testing begins October 2014. 8602_Mars Society_T.May.15 Building Toward First Flight 09/2011 Tested Booster Development Motor 07/2012 Delivered RS-25 Engines to Inventory 07/2013 Competed Preliminary Design Review 10/2011 - 12/2013 Tested SLS Wind Tunnel Models 07/2013 Completed First Confidence Barrel Section Welding 10/2013 Completed Thrust Vector Control Test 11/2013 Conducted Adaptive Augmenting Control Flight Test 12/2013 Completed LOX Forward Dome Manufacturing Demo ACCOMPLISHMENTS 1/2014 Conducted Avionics “First Light” in Integration Facility 02/2014 Shipped Multi-Purpose Crew Vehicle Stage Adapter for EFT-1 CURRENT Complete Manufacturing Tooling Installation 10/2014-15 Test Main Engines, Boosters , & Core Stage Structure 07/2015 Complete the SLS Critical Design Review 06/2016 Assemble the Core Stage Assembly and Test Fire 07/2017 Stack the SLS Vehicle WHAT’S NEXT WHAT’S 12/2017 Transport SLS from the VAB to the Launch Pad 8602_Mars Society_T.May.16 .
