NASA Targets Reduced Water Usage for Long Duration Missions

NASA Water Recovery System

Water is essential for human survival on Earth and in space. A typical person requires between 3.5 to 15 liters per day. Yet launching large quantities of water up to the International Space Station (ISS) is terribly expensive, and would be a major impediment to future space settlement. So NASA has made water recycling a vital part of closing the life support “loop”. Meanwhile, water is often in short supply even on the Earth, especially in a clean, drinkable form.

Veggie plant growth chamber

A transparent plastic growth chamber bound for the International Space Station on the SpaceX-3 resupply mission may help expand in-orbit food production capabilities, and offer astronauts fresh produce.

NASA’s Veg-01 experiment will be used to study the in-orbit function and performance of a new expandable plant growth facility called Veggie. Veggie is a low-cost plant growth chamber that uses a flat-panel light bank that includes red, blue and green LEDs for plant growth and crew observation. Veggie’s unique design is collapsible for transport and storage and expandable up to a foot and a half as plants grow inside it. The roots and nutrients for the plant are contained in plant “pillows”. The investigation will focus on the growth and development of “Outredgeous” lettuce seedlings in the microgravity environment.

The eXploration Habitat (X-Hab) 2015 Academic Innovation Challenge is a university-level competition involving hands-on design, research, development, and manufacture of functional prototypical subsystems  for space habitats and deep space exploration missions. The Advanced Exploration Systems (AES) Exploration Augmentation Module (EAM) project will offer multiple X-Hab awards of $10k – $20k each.

NASA will  benefit from the challenge by sponsoring the development of innovative concepts and technologies from universities, which will result in innovative ideas and solutions that could be applied to exploration.

Sub-Arctic Biodome: Prototype for Space Settlement?

Posted on by

EOS logoThe Earth Organisation for Sustainability (EOS) is building a geodesic biodome near the edge of the Arctic Circle, with the goal of self-sufficient food production. EOS has received an European Union grant of 34,000 €  delivered by URnära, for construction materials and initial wages, and is working with Green Free Will.

The EOS is developing both technology and social systems for self-sufficent communities of the future. So the Biodome can provide lessons for developing space settlements, such as on Mars. Umeå is in Northern Sweden, just a few hundred kilometres from the Esrange Space Center in Kiruna. Though Umeå is not as far north as the Flashline Mars Arctic Research Station near Resolute, Canada, sunlight is in short supply much of the year, and temperatures can get as cold as -38C (-36 F).

NASA Ames Sustainability Base wins a 2013 GEELA Award for the category of Sustainable Practices or Facilities. The GEELA Program, which stands for Governor’s Environmental and Economic Leadership Awards, is run by the California Environmental Protection Agency (Cal/EPA).

Introduction

NASA’s first sustainable space “settlement” is located in the heart of Silicon Valley, at the NASA Ames Research Center in California. “Using NASA innovations originally engineered for space travel and exploration, the 50,000 square-foot, lunar-shaped Sustainability Base is simultaneously a working office space, a showcase for NASA technology and an evolving exemplar for the future of buildings.” (Ames website). Through a combination of NASA innovations and commercial technologies, Sustainability Base leaves virtually no footprint.

Project Possum at the Edge of Space

Project PoSSUM (Polar Suborbital Science in the Upper Mesosphere) seeks nearly invisible clouds at the literal edge of space. These noctilucent clouds may be important indicators of climate change. Yet to get a good look at them requires getting up close, and that requires a spacecraft.

Noctilucent clouds are of interest within the climate science community as sensitive indicators for what goes on in the upper-mid atmosphere. “If we can understand more about this, we can understand more about global changes,” according principle investigator Dr. Jason Reimuller, “how the upper atmosphere is coupled with the lower atmosphere.”

 

According to the Project’s website, the extremely cold temperatures and very low density of the mesosphere creates an environment where very small changes in the atmosphere can drive large changes in observed noctilucent cloud properties.  So by observing noctilucent clouds, we can learn a lot about the atmosphere as a whole.

PoSSUM uses imaging and remote sensing techniques from commercial, reusable suborbital space vehicles to address critical questions about the climate, and has developed its own instrumentation. PoSSUM Observatory obtains high-altitude imagery and remote sensing data, and capture mesoscale phenomena in the atmosphere or on the ground. It also includes LiDAR and thermal mapping capabilities and can be readily integrated on-board suborbital spacecraft. The PoSSUM Aeronomy Laboratory contains Mesospheric Aerosol Sampling Spectrometer (MASS), Mesosphere Clear Air Turbulence (MCAT) and wind probe components.

Sounding rockets aren’t good enough. They aren’t in the neighborhood for long enough, and it is difficult to get high quality images as well as collateral atmospheric measurements such as temperature and pressure. So PoSSUM is designing its 2015 campaign experiment around the XCOR Lynx for a delpoyment to either Fairbanks, AK or Kiruna, Sweden

If you are interested in flying an experiment on a PoSSUM flight, they also have a Possum Guest Experiment facility.

NRP event

Rose Grymes, Rama Nemani,  Stanley Herwitz,

The NASA Research Park (NRP) held “Planetary Sustainability for Survival and Profit”, a presentation and audience Q & A on the evening of December 3 at Moffett Field as part of its Exploration Lecture Series.

Speakers presented on several sustainability-related start-ups at the NASA Research Park, including Bloom Energy, Bio-Vessel (in stealth mode), and Oyokits. Panalists spoke about other endeavors such as the Space Portal,  NEX, a warehouse and collaboration platform for Earth data, the UAV Collaborative, and the Smart Energy Enterprise Development Zone (SEEDZ).
