The Space Station’s New 3-D Printer Recycles Old Plastic Into Custom Tools

Last week, Northrop Grumman’s Cygnus spacecraft departed the International Space Station, having delivered a batch of new experiments and cargo. Among them was the Refabricator, a new machine that will not only make objects on demand things for the astronauts, it will recycle them too.

While 3-D printers are becoming commonplace, nowhere are their benefits more obvious than in the confines of space. Cargo resupply missions to the ISS are routine, but as human spaceflight pushes farther out into deep space, there will be more pressure for self-sufficiency, as resupply missions become more difficult and expensive. That means not only manufacturing supplies, but also conserving and reusing the supplies on hand.

Re-use and Recycle

The Refabricator is in part a 3-D printer, allowing astronauts to make tools to their own specifications immediately, without waiting months for items to be flown from Earth. But there’s been a 3-D printer on the ISS since 2014. The Refabricator stands out because it’s able to recycle things it’s already printed and turn them into new materials.

It can even create the raw 3-D printer filament from old packing supplies, like the foam and plastic shipping materials NASA uses to pack its cargo for the trip to space. Most 3-D printers cannot reuse plastics once printed, because the way they print weakens the plastic’s integrity. But the Refabricator uses a different printing method, so that it can reprint the same material many times.

NASA hopes the new printer/recycler will both free up space on future resupply launches and reduce overall waste on the ISS. It could even lead to 3-D printers on Earth that one day use the items we normally put on the curb, like water bottles or plastic bags, to create brand new custom materials for our homes.

Tethers Unlimited, Inc. developed the Refabricator for NASA’s In-Space Manufacturing Office. Their whole creation fits into a cube about the size of a minifridge. The company can monitor the Refabricator from Earth, but astronauts on the ISS will perform the operations.

For this first test flight, that will mean having the Refabricator print, recycle, and re-print creations up to seven times in a loop, to prove that the material doesn’t weaken with repeated recycling. Those final printings will then be delivered back to Earth for testing – in particular, to see if and how the printing process differs in space from on the ground.

Yukon and Northern BC First Nations tackle climate change using Indigenous knowledge and science

Published

By

YUKON, June 18, 2021 /CNW/ – The Government of Canada is working together in partnership with Indigenous and Northern communities in finding solutions to adapt to the impacts of climate change in the North.

Today, Minister of Northern Affairs, Daniel Vandal, along with Parliamentary Secretary to the Minister of Economic Development and Official Languages (Canadian Northern Economic Development Agency), Larry Bagnell, highlighted progress on three unique, Indigenous-led projects that are helping communities in Yukon and Northern British Columbia adapt to the challenges posed by climate change.

The Minister and Parliamentary Secretary met virtually with Carcross/Tagish First Nation (C/TFN) to learn about their community-led climate change monitoring program. C/TFN has partnered with Tsay Keh Dene Nation (TKDN) and Chu Cho Environmental of Prince George, British Columbia, to build a community-led monitoring project that examines environmental data and Indigenous knowledge to create a holistic picture of how the climate is changing across C/TFN and TKDN traditional territories. The project combines tracking of current and historical climate trends with knowledge shared by Elders while also providing opportunities for youth mentorship and climate change awareness.

The Taku River Tlingit First Nation (TRTFN) is also leading a unique project to assess the impacts of climate change within their traditional territory. Climate change is causing many of the culturally significant ice patches to melt, exposing organic artifacts to oxygen and leading to rapid deterioration. The TRTFN ice patch mapping project will involve performing archaeological assessments to prevent the degradation of artifacts. Research will be guided by traditional knowledge, Elders and oral histories, when available, and heavily involve community, Elders, youth and Knowledge Keepers.

The Pelly Crossing Selkirk Development Corporation is leading the Selkirk Wind Resource Assessment project through the installation of a Sonic Detection and Ranging (SODAR) system. The initiative includes a feasibility study leading up to the construction of a renewable energy facility, including wind, solar and battery energy storage. Expanding clean energy within the region will have direct benefits for communities, including reduced reliance on diesel, job creation and revenue generation for Selkirk First Nation. 

These projects are delivering important environmental, social and economic benefits that lead to healthier, more sustainable and resilient communities across Yukon and Northern British Columbia. They also build community clean energy capacity and help to avoid the impacts of climate change.

Atlantic Provinces Ready For Aquaculture Growth

Published

Aquaculture is an important economic driver for rural, coastal and Indigenous communities, and Atlantic Canada is well positioned to increase aquaculture production as global demand for sustainably sourced seafood grows.

That is why the ministers responsible for aquaculture in the Atlantic provinces have agreed to the ongoing development and management of their industries based on common principles. A new memorandum of understanding has been signed by the four ministers, which extends the previous agreement signed in 2008.

“In a time when food security is especially important, it is good to see our aquaculture industry has grown steadily and is poised for continued growth in 2021 based on environmentally responsible, science-based policies and practices,” said Keith Colwell, Minister of Fisheries and Aquaculture for Nova Scotia. “Our Atlantic partnership continues to help the industry grow sustainably.”

Cooperation between the provinces and the aquaculture industry has led to improvements in pest management, environmentally sustainable aquaculture methods, aquatic animal health and policies to support the shared use of marine and freshwater resources. It also aims to align regulation and policy between the provinces to make the regulatory requirements easier to understand by industry and the public.

Each province has a comprehensive and robust legislative and regulatory framework to ensure environmental sustainability, economic prosperity and public accountability. The provinces update their legislation and regulations regularly. Nova Scotia revamped its regulatory framework in 2015; New Brunswick received Royal Assent for a new Aquaculture Act in 2019 and is working on the supporting regulations; Newfoundland and Labrador completely revised its aquaculture policy in 2019; and Prince Edward Island has recently drafted a new Aquaculture Act.

The ministers have agreed to continue to use science-based evidence for management decisions, thereby increasing public and investor confidence in the Atlantic Canadian aquaculture industry.

COMING SOON: A Healthy Environment and a Healthy Economy 2.0

Published

By

We all want the same thing: a clean and responsible energy future for our children and future generations while continuing to enjoy a high standard of living.

On December 11, 2020, the Prime Minister announced a new climate plan which he claimed will help achieve Canada’s economic and environmental goals.

The proposed plan by Environment and Climate Change Canada (ECCC) entitled “A Healthy Environment and a Healthy Economy” will have an initial investment of $15 billion of taxpayer’s money. It is built on 5 pillars of action:

  1) Making the Places Canadians Live and Gather More Affordable by Cutting Energy Waste

2) Making Clean, Affordable Transportation and Power Available in Every Community

3) Continuing to Ensure Pollution isn’t Free and Households Get More Money Back

4) Building Canada’s Clean Industrial Advantage

5) Embracing the Power of Nature to Support Healthier Families and More Resilient Communities  

In my paper, “A Healthy Environment and a Healthy Economy 2.0” I will objectively critique each pillar in the government’s new climate plan and provide alternative solutions to the same issues.

  This is an alternative plan that supports workers, protects lower income earners and creates economic growth while respecting the environment and focusing on the dignity of work.

  This plan abandons virtue-signaling projects and relies on Canadian ingenuity to build our economy and restore Canada’s role of responsible leadership in the world.
