Will A 25 Year Old Space Pen Still Write?

A pen designed to write in space sits unopened for 25 years. Does it still work?In this episode of Field Notes, Michael Stevens finally opens a treasured souvenir from his time at Space Camp: a genuine Fisher Space Pen that has been waiting decades for its first scribble. From there, the conversation launches into the challenges of living in space, why astronauts abandoned pencils, and what happens to your sense of direction when gravity disappears.Along the way they investigate whether eight billion people clapping could damage a building, discover why the ISS is constantly falling towards Earth, and ask whether the Kardashev Scale tells us anything meaningful about the future of civilisation.-------------------For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
