2013 Experimental Program to Stimulate Competitive Research (EPSCoR) Grant
The most recent EPSCoR grant will to be dispersed over three years and will support the Multi-Purpose Research Station in North Dakota in support of NASA’s future human missions to Mars 2015-2018. This $750,000 grant will support research and infrastructure needs of the UND Inflatable Mars Lunar Habitat and increase the of availability for Graduate Research Assistantships for UND students.
This project focuses on expanding the current IMLH to include 4 new modules:
The incorporation of these modules will increase the fidelity of analog simulations and allow for research projects and future cooperation efforts between UND and outside institutions.
ND PLANETARY EXPLORATION INITIATIVE
As part of the NASA EPSCoR CAN 2009 grant, “Integrated Strategies for the Human Exploration of the Moon and Mars,” our team is developing an Inflatable Lunar Habitat (ILH) and building two electrical rovers. Once finished, these prototypes will be tested, together with two NDX-2 space suits, in the Badlands of North Dakota, USA. This project will allow the team to develop a complete minimal mission scenario to attempt and address all the different problems related to a human mission to the Moon or Mars.
INFLATABLE LUNAR HABITAT (ILH)
The Inflatable Lunar Habitat (ILH) consists of a rigid frame that is covered by an inflatable bladder. This arrangement allows both tensile and compressive loads to be transferred from the soft fabric to the rigid frame, avoiding punctures or penetrations. The inflatable material is malleable and retains strength during folding. It is also lightweight and stows in a significantly smaller volume. An expandable soft goods structure offers a lower mass solution, with increased volume versus using metal or rigid composite materials. The UND ILH is being built for a crew of four astronauts whose mission’s duration is six months. The interior consists of four sleeping compartments where the astronauts are able to rest as well as stow their personal belongings. Inside the ILH, there is also a small galley/dining room, a bathroom, and plenty of laboratory space. The habitat is about 40 ft long, 10 ft wide and 8 ft high and was completed in 2012.
ANALOG MISSIONS To date there have been three analog missions conducted in the habitat. The initial 10-Day analog mission took place in October-November 2013, the second mission was a 30-Day analog mission. The third was a 10-day isolation analog mission that was meant to simulate the initial landing period on Mars when there would be no opportunity to explore outside of the habitat due to the effects of microgravity on the human body. The mission crews were Space Studies graduate students, of which 3 were inside the habitat in each mission, with mission support crew available 24/7 to assist them in missions and logistics..
The project involves the design and construction of two electrical rovers: one Pressurized Electric Rover (PER) and one Unpressurized Electric Rover (UPER). The PER will provide accommodation for a crew of two astronauts during missions and an additional two members in an emergency situation. It will also contain a common airlock interface between both the astronauts’ space suits and their habitat. This will allow the crew to exit the rover safely onto the planetary surface in their suits and to enter the habitat unsuited while wasting as little expelled gas as possible.
This preliminary design is being built with the cooperation of Cirrus Design of Grand Forks and consists of a converted electric vehicle, enclosed with a composite shell. It is equipped with communication systems and a station to store soil samples for transportation back to the habitat. The 1G testing of this pressurized rover will show the feasibility of the common airlock system, its ability to safely and reliably conduct experiments and easily transport its crew across rough terrain.
In cooperation with NASA’s Marshall Space Flight Center, the rover and habitat will be outfitted with sample collecting boxes. These boxes will be transferred into the rover during field testing via a secure mini airlock. The airlock will be located on the floor of the back of the rover, between the two planetary exploration suits. Once inside, the sample boxes will be transferred into the habitat through the entry way. The samples can be opened and manipulated inside the lab using a glove box built by the Marshall Space Flight Center.
Currently, with several NASA’s future scenarios to return to the Moon and for the exploration of Mars any astronaut will be in need of transportation to conduct experiments, operations, and have a place of safety in case of emergency. Having a pressurized lunar rover may be the only practical way for any future human missions to the Moon or Mars to be productive and safe at the same time.
The UPER will be based on the same initial PER design. It shall accommodate a four-member crew and it will serve as a transport back-up for the PER for eventual problems such as derailment on soft terrain, mechanical failures, etc.
