Researchers at NASA’s Kennedy Space Center in Florida are testing discs made of “space trash”— including plastic water bottles, clothing scraps, duct tape and foil drink pouches– to see whether they can be reused as radiation shields during deep-space missions.

The small, circular disc tiles were made at the NASA Ames Research Center in California using a special compactor that melts trash without incinerating it. The compactor transforms a day’s worth of garbage into a solid 8-inch diameter tile about half an inch thick.

Researchers believe the discs have the potential to be used as radiation shields because of the high amount of plastic packaging in the trash.

“The idea is to make these tiles, and, if the plastic components are high enough, they could actually shield radiation," says microbiologist Mary Hummerick in a news release on the NASA website.

Increased radiation shielding could be useful in astronauts’ sleeping quarters, or in regions of the spacecraft where the crew is exposed to solar flare effects.

Hummerick and the team at the Space Life Sciences Lab at Kennedy are currently evaluating whether the heating and compaction process is effective in killing bacteria on the tiles.

So far, so good.

"They are achieving sterilization for the most part," Hummerick says. "What we don't know is, can a few possible surviving bacteria go inert and then grow back."

Researchers also hope the compaction process will help remove water—a valuable commodity in space—from trash so that it can be re-used by space crews.

The handling of waste disposal is a crucial consideration for NASA mission planners. Cramped quarters and extremely limited resources are just some of the challenges that planners and astronauts face during long-range missions. Space crews cannot simply throw trash overboard.

“We don't want to contaminate the surface of an asteroid or something just by throwing the trash out the door," says microbiologist Richard Strayer in the news release. "If NASA doesn't do something about it, then the spacecraft will become like a landfill, with the astronauts adding trash to it every day.”

7 Key Habits of Super Networkers

7 Key Habits of Super Networkers | ITGabs News | Scoop.it

The ability to network successfully can be one of the greatest assets in business. It allows some people to find incredible opportunities, while others just watch from the sidelines.


Here are seven of the most important habits to develop:


1. Ask insightful questions.
Before attending networking events, get the names of the people who are expected to attend and search social media sites like LinkedIn to figure out which topics they're probably most interested in.


2. Add value.
One of the most powerful networking practices is to provide immediate value to a new connection.


3. Learn their 'story.'
Ask successful entrepreneurs to tell you how they got where they are. Most people think of this as an exercise in rapport building, but hearing these stories can tell you a lot about a person's approach to business.


4. Share a memorable fact.

Mention something personal that defines who you really are.


5. Keep a list.

Lists give you something to reference in conversation the next time you meet.


6. Make small promises and keep them.

No matter how small a promise you make -- such as sending an email or returning a phone call -- delivering on that promise reflects on your character.


7. Reward your 'power' contacts.

Keep a list of your top five to 10 networking partners and do something each week to add value to one person's life or business.
