Magnetic sails could put the brakes on interstellar space probes

14 hours agoTechnology / Gadgets : Gizmag

Our nearest stellar neighbor, Alpha Centauri, is just four light-years from Earth, and while that's pretty close in the grand scheme of things, we can't just pop over to borrow some milk. With our current technology, the journey would...Show More Summary

Momentum braking in deep space

With a miniaturised space probe capable of accelerating to a quarter of the speed of light, we could reach Alpha Centauri, the nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past. Show More Summary

Interstellar space probes: Where's the brakes?!

(Goethe University Frankfurt) With a miniaturized space probe capable of being accelerated to a quarter of the speed of light, we could reach Alpha Centauri, our nearest star, in 20 to 50 years. However, without a mechanism to slow it down, the space probe could only collect data from the star and its planets as it zoomed past. Show More Summary
