Introduction: This talk will introduce the preliminary findings in support of NASA’s Future
Capabilities Team. In support of the ongoing studies conducted by NASA’s Future
Capabilities Team, we are tasked with collecting research objectives for the Proving Ground
activities. The objectives could include but are certainly not limited to: demonstrating crew
well being and performance over long duration missions, characterizing lunar volatiles,
Earth monitoring, near Earth object search and identification, support of a far-side
radio telescope, and measuring impact of deep space environment on biological
systems.
Beginning in as early as 2023, crewed missions beyond low Earth orbit will begin enabled
by the new capabilities of the SLS and Orion vehicles. This will initiate the “Proving
Ground” phase of human exploration with Mars as an ultimate destination. The
primary goal of the Proving Ground is to demonstrate the capability of suitably long
duration spaceflight without need of continuous support from Earth, i.e. become Earth
Independent.
A major component of the Proving Ground phase is to conduct research activities aimed
at accomplishing major objectives selected from a wide variety of disciplines including but
not limited to: Astronomy, Heliophysics, Fundamental Physics, Planetary Science, Earth
Science, Human Systems, Fundamental Space Biology, Microgravity, and In Situ Resource
Utilization. Mapping and prioritizing the most important objectives from these disciplines
will provide a strong foundation for establishing the architecture to be utilized in the Proving
Ground.
Possible Architectures: Activities and objectives will be accomplished during the
Proving Ground phase using a deep space habitat. This habitat will potentially be
accompanied by a power/propulsion bus capable of moving the habitat to accomplish
different objectives within cis-lunar space. This architecture can also potentially support
staging of robotic and tele-robotic assets as well as sample-return.
As mission durations increase from 20 days to 300 days, increasingly ambitious
objectives may be undertaken including rendezvous with an asteroid or other near-Earth
object.
Research activities can occur inside the habitat, outside the habitat, via externally
mounted instruments, or using free flying satellites/landers.
Research Objectives: Primary mission objectives are listed below. In order to help define
details of the mission architecture, including the means by which the architecture can be
supported, more specific research objectives are needed.
Title/Objective
Crew Transportation/Provide ability to transport at least four crew to cislunar
space
Heavy Launch Capability/Provide beyond LEO launch capabilities to include
crew, co-manisfested payloads, and large cargo
In-Space Propulsion/Provide in-sapce propulsion capabilities to send crew and
cargo on Mars-class mission durations and distances
Deep Space Navigation and Communication/Provide and validate cislunar and
Mars system navigation and communication
Science/Enable science community objectives
Deep Space Operations/Provide deep-space operation capabilities: EVA,
Staging, Logistics, Human-robotic integration, Autonomous operations
In-Situ Resource Utilization/Understand the nature and distribution of volatiles
and extraction techniques, and decide on their potential use in the human
exploration architecture
Deep Space Habitation/Provide beyond LEO habitation systems sufficient to
support at least four crew on Mars-class mission durations and dormancy
Crew Health/Validate crew health, performance, and mitigation protocols for
Mars-class missions
