This is Scientific American 60-Second Science. I'm Christopher Intagliata. Got a minute?

隐藏原文=

It's a scenario straight out of Hollywood: You're up in a spacecraft, "you've got this capsule around you," and a loose bolt, a piece of space junk, is zooming your way.

隐藏原文=

"And it's going really fast.

点击显示原文

隐藏原文=

It's going to very likely pass through your spacecraft and leave both entry and exit holes.

点击显示原文

隐藏原文=

So all of a sudden now your atmosphere is rushing out those holes, and you want them sealed right away."

隐藏原文=

That's Timothy Scott, a polymer scientist at the University of Michigan, Ann Arbor.

点击显示原文

隐藏原文=

He and his team have devised a potential solution to this space disaster: a material that patches itself up, less than a second after impact.

隐藏原文=

Think of an ice-cream sandwich.

点击显示原文

隐藏原文=

"The central part, the ice cream of our sandwich, is a liquid resin."

点击显示原文

隐藏原文=

The cookie parts are sheets of thermoplastic.

点击显示原文

隐藏原文=

When a projectile—or piece of space junk, punctures the sandwich, it exposes the liquid part to the ship's oxygen, which causes it to solidify, patching the hole.

点击显示原文

隐藏原文=

The researchers tested sheets of the self-healing material at a firing range, filming the results with high-speed video.

点击显示原文

隐藏原文=

And indeed, the material worked fine here on Earth—but they say the findings will have to be replicated under pressure conditions like those you'd find in space.

点击显示原文

隐藏原文=

The results are in the journal ACS Macro Letters.

点击显示原文

隐藏原文=

The space station is already well protected by bumpers that vaporize particles on impact.

点击显示原文

隐藏原文=

But protection doesn't come cheap.

点击显示原文

隐藏原文=

"It turns out that robust things are also very heavy.

点击显示原文

隐藏原文=

The intent of this is really to provide a backup that's very low weight."

点击显示原文

隐藏原文=

It costs some $10,000 a pound to launch equipment into space today.

点击显示原文

隐藏原文=

So a lighter weight material could save money and lives.

点击显示原文

隐藏原文=

Thanks for the minute, for Scientific American 60-Second Science. I'm Christopher Intagliata.
