Imagery for CHAPEA Sandbox Cyclorama.

In the start of 2022 Afterconcepts, was awarded a subcontract supporting the Crew Health and Performance Exploration Analog (CHAPEA) to deliver high-resolution realistic imagery portraying a Mars-like landscape to improve the fidelity of the simulation of the CHAPEA project. ,  at the Johnson Space Center in Houston. This project was completed as part of NASA’S Human Exploration and Operations Mission Directorate (HEOMD) and the one-year-long analogue missions are anticipated to begin in Fall 2022.

CHAPEA Project.

( Crew Health and Performance Exploration Analog )

CHAPEA is a series of analogue missions that will simulate year-long stays on the surface of Mars. Each mission will consist of four crew members living in Mars Dune Alpha, an isolated 1,700-square-foot habitat. During the mission, the crew will conduct simulated spacewalks and provide data on a variety of factors, which may include physical and behavioural health and performance.

The major crew activities during the analogue may consist of simulated spacewalks including virtual reality, communications, crop growth, meal preparation and consumption, exercise, hygiene activities, maintenance work, personal time, science work, and sleep.

CROP AREA

 A 3D-printed habitat, known as Mars Dune Alpha, at the Johnson Space Center in Houston. ICON utilized the Vulcan construction system to complete a 1,700 square-foot structure, designed by architecture firm BIG (Bjarke Ingels Group), that will simulate a realistic Mars habitat supporting long-duration, exploration-class space missions.

In order to maintain isolation of the Crew Health and Performance Analog (CHAPEA) crew members during simulated extra-vehicular activities (EVA) exercises in the CHAPEA facility sandbox, an inflatable cyclorama has been designed to enclose the sandbox.

EVA is any activity performed by a pressure-suited crewmember in unpressurized or space environments. EVA begins with depressurization of the airlock or space module and ends with repressurization of the space module or airlock after crewmember ingress. This includes any internal activities where a pressure-suited crewmember may be operating in normal modes of operation (e.g., airlocks, passageways, unpressurized work areas, donning/doffing areas) and abnormal modes of operation (e.g., unpressurized modules).

 Given Critrea

  • The imagery shall be generally cohesive and seamless across the different sections of the cyclorama to create a high-fidelity simulation. Some small areas of interface with structure or sharp corners will be allowed some discontinuities where they cannot be avoided.

  • The top sections of the cyclorama, sections 7 and 8 have translucent White fabric that can be backlit with various color LED in order to simulate various sky conditions such as normal daylight (“butterscotch-like” color), morning and evening (a “dusty blue like” horizon in the direction of the sun), or a “dusty mars red” color for the entire sky to simulate a mars sandstorm condition.

  • The imagery shall integrate in color with the color of the sand that has already been installed in the sandbox.

Multiple iterations of the Mars environment were generated using the open-source software "Blender" while adapting and colour correcting the materials and textures that are presented in the scenery to match the provided references from the preservance mission and pictures of the sand filled in the sandbox.

The imagery simulates that being in the bottom of a canyon or valley was given the height constraint of 8ft.The canyon/valley wall has a vertical height of ≤8 feet to not have the canyon walls caving in on the person due to the curvature of the cyclorama.

The canyon/valley walls stretch the entire length of sections 1 (~25 feet), 2 (~14 feet) & 3 (~59 feet).  Other sections 4,5,6 shall have complimentary Mars scenery, with different typical mars scenes.  Loose and scattered rocks in the imagery nearest the floor areas will help visually obscure hard interfaces and corners and are recommended.
