Solar-powered Sail Can Travel Forever, And It's The Future Of Space Exploration - Fast ...

By

Called a "solar sail," the silvery sheet of fabric is 32 times thinner than a human hair and stretches the size of three basketball courts. Over a recent Zoom call, Johnson says the sheet of fabric works much like a sail used for boats—if a boat sail were designed for high-speed space travel. "Just as a sailboat uses the wind to push it through the water, solar sails use the pressure of sunlight to push them through space," Johnson says.

This seemingly impossible feat is, in fact, not impossible at all. Avi Loeb, an astrophysicist and Director of the Institute for Theory and Computation at the Center for Astrophysics at Harvard University, says solar sails represent one of the most promising technologies for future space exploration. They offer a sustainable and efficient way to navigate the cosmos, with the potential to propel spacecraft to unprecedented speeds and distances.

SANTA CRUZ, CALIFORNIA "Dad, did you ever imagine that your formula would become so famous?" I ask the kind-eyed, 91-year-old person next to me on the patio. My dad, Frank Drake, is quiet for a moment. Perhaps he's thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind's hunt for extraterrestrial civilizations.

UFO Hunting, With Harvard Data: Astrophysicist Advocates For Scientific Investigation

Avi Loeb: Two things. In 2017, there was an object — the first one that was identified from outside the solar system that arrived close to Earth — and it didn't look like anything we've seen before. It didn't look like a comet, it didn't behave like an asteroid. Loeb: Yes. And I thought maybe it's artificial in origin. And, in fact, I wrote a book about it, Extraterrestrial, that was published six months ago. And then a month ago, there was a report delivered to Congress saying: there are things in the sky above the U.S. whose nature is not identified.
