Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To send a spacecraft, weighing roughly 1,000 kilograms, to a neighboring star ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...

Scientists propose using relativistic electron beams to propel spacecraft, offering a new hope for interstellar travel within a human lifetime.

Delft, The Netherlands / Hsinchu, Taiwan -- Ocotober 13, 2008 -- MAPPER Lithography and Taiwan Semiconductor Manufacturing Company (TSMC) signed an agreement, according to which MAPPER will ship its ...

He shares the results of his electron-beam lithography experiments in his latest video (embedded below). In e-beam lithography, or EBL, shapes are drawn onto a wafer using an electron beam in a ...

A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.

But some projects are designing ways to propel payloads to the nearest star system (Alpha Centauri) using beams of electrons. A new proposal uses an electron beam fired from a stable platform near ...

A new technical paper titled “Sensitivity and contrast of indium nitrate hydrate resist evaluated by low-energy electron beam ...
