What is a Whipple shield? #scienceproject



Learn how to protect the International Space Station and satellites from space debris by building and testing your own model Whipple shield! Written instructions for this science project are available on the Science Buddies website: https://www.sciencebuddies.org/science-fair-projects/project-ideas/SpaceEx_p051/space-exploration/whipple-shield-space-debris?ytid=D6MhnSh6s3I&ytsrc=description

Science Buddies also hosts a library of instructions for over 1,500 other hands-on science projects, lesson plans, and fun activities for K-12 parents, students, and teachers! Visit us at https://www.sciencebuddies.org/?ytid=D6MhnSh6s3I&ytsrc=description to learn more.

this is a model of a Whipple Shield Whipple Shields are used to help protect some spacecraft from impacts by space debris because even something as small as a Fleck of paint can do a lot of damage when it’s traveling thousands of miles per hour the basic idea behind a Whipple Shield like the one pictured here is not to always completely stop debris it’s to break the debris up into smaller pieces and spread the impact over a larger area so it doesn’t puncture the outer wall of a spacecraft this doesn’t NE necessarily help protect against large debris but it does help with smaller pieces of debris that are too small to track

  1. Much easier to plug and patch than hull plating, thats actually a big upside in the logistically challenging arena known as space. The weight of the primary material used in construction is going to determine what sort of things you can use to fix it. You cant afford to lug around several tons of spare plate metal sheets and youd struggle to make a timely repair on any craft we built that heavily given the other limiting factors such as total current single launch lift capacity making the building of larger craft unrealistic. Kinda just leaves a tiny armored box full of more armor and people in vacuum sealed welding suits.

    Instead somebody can tape more foil over a bunch of small holes and move on with the mapping of the universe. Sheets of flexible metal with adhesive on one side can just be tossed at the pressure leak and the escaping gas basically applies the patch for you. Fire and forget patching is pretty sophisticated stuff if you ask me. A lot of stuff has to be made very well at a high level of technical refinement for the fix to be that simple and effective AND for it to get more effective the worse the leak is given its not a huge blowout.

  2. Planetes is going to come true sooner rather than later. Someone could make a whole lot of money (or rather, with the expense of space flight, break even) cleaning up space debris.

  3. its like in the movies, when the protagonist falls out a window, but hits every cloth/canvas awning on the way down, allowing them to survive the 10-story fall (or however many awnings they rip through before slowing down too much to keep falling)

  4. And to think my countless space adventures in my imagination as a kid I never considered a pebble traveling at Mach speeds would have stopped me before the aliens🤦🏼‍♂️😂

  5. What's not mentioned while hopefully being obvious, is these shields are thick, usually 1-3MM thick, I know it may not seem like a lot, but this is enough to stop a lot of objects, and still protect the spacecraft. They've been experimenting with other kinds of shielding.

  6. It was, incredibly, also seriously considered for armor against NUKES back in the cold war days when they were thinking about war in space. Makes sense when you think about it, in space, there's no atmosphere to propagate a shockwave, just a lot of LOW MASS, high energy output, lasting only a fraction of a second. Sure, the outer layer or 2 would be annihilated, but a few layers of foil would effectively stop an entire nuclear weapon from even touching a space craft. Neat huh?
