MISSION TO UND
The University of North Dakota (UND) Space Studies Program is one of the few facilities funded by NASA (since 2015) to test how extensive extraterrestrial mission durations have on the human body. These tests are carried out in the Inflatable Lunar Mars Habitat (ILMH), led by Principal Investigator Dr. Pablo de Leon, for missions ranging anywhere from 14-30 days. The program plans to extend these missions to 45-60 days. The ILMH system consists of the following modules: Living Quarters, Geology Lab, ExtraVehicular Activities, Exercise and Human Performance, and the Greenhouse. Dr. Pablo de Leon, Principal Investigator at the University of North Dakota directing research in their Inflatable Lunar Mars Habitat (ILMH), cited that with current manual configuration of their greenhouse employed on their last four missions,
"the crew spent up to 60% of the working day tending to the greenhouse......
and this is a problem that the astronauts will have to face on long duration missions. Long duration missions will be plant based because they cannot take with them much animal protein," said De Leon. Due to the orbital arrangement of Mars in relation to Earth, efficient launches to and from the two planets are only possible every 26 months, meaning that astronauts could be out of physical contact with earth and plant based matter for over two years. Mars One estimates the cost of bringing the first four people to Mars at $6 billion. This is the cost of all the hardware combined, plus the operational expenditures, plus margins. For every next manned mission including hardware and operations, Mars One estimates the costs at $4 billion.
Projecting this expenditure across the 26 month long mission duration, every hour each astronaut spends on Mars costs $77,543. This means that every week it costs $775,430 just to provide fresh produce at this rate.
Installation of Box Farm units to automate this process is vital to the success of these missions, since scientists on these missions would have more of their precious time open to do valuable research. Dr. Pablo de Leon further validated how critical a system like Box Farm is to mission success, quoting "We need to consider an automated system for the greenhouse since it requires too much time to take care of” in a telecon interview with the Box Farm team [16 Oct. 2018].
On May 18th, the Box Farm Mission 7b crew consisting of Sean Agpaoa, Gabor Paczolay, James Thesken, and Preston Tran, entered the habitat for a fully isolated 6 day mission. The Mission 7b crewmen, the first to wholly consists of non-UND personnel, were the first to occupy all the bunks in the habitat. The Box Farm system that was transported over 4,000 miles and assembled was the first automated system installed in a Lunar/Martian analog habitat. This mission proved the viability of being packaged into a small enough payload for future aerospace missions due to its modular configuration.
The crew unpacked and assembled the system in 16 hours. The following day was spent testing and fine tuning the system to UND ILMH Greenhouse's configuration and holding a media day for North Dakota's press.
While testing the Box Farm system, the crew had daily tasks of habitat maintenance and routine psychological evaluations. The crew had to prepare their own meals, which were stocked prior to the start of the mission. Due to the closed nature of the mission, the crew had to be resourceful and only had access to tools and supplies in the habitat to solve unanticipated difficulties.
"My first look at Box Farm is that it is excellent work, very well designed and mechanically very sound, using state-of-the-art technology in some cases... it's impressive that this was all put together in less than a year," said De Leon.
