What if traveling to exoplanets were no longer the realm of science fiction?
"Setting priorities is always a matter of weighing costs and benefits," Gerald Jackson, co-founder and president of Hbar Technologies Inc. and the author of a new paper investigating the idea of using antimatter-based propulsion for exoplanet exploration, told Space.com in an email."Is antimatter-based propulsion for interstellar travel more important than childhood glioma in the next year? Of course not.
"There are many scenarios where humanity may find that it needs to quickly send spacecraft into interstellar space," he said. "In my opinion antimatter-based propulsion is the best solution for such a need." Jackson's study focuses primarily on the physics responsible for the propulsion system to work, with an emphasis on; the paper describes an electrostatic nozzle and trap meant to carry out the necessary fission. So when could we expect this antimatter-based propulsion technology to actually be developed? This is a common question but also a common trap, Jackson said.
"Robert Goddard developed liquid fuel rockets, staging, and gyroscopic guidance systems long before they were needed for manned [sic] exploration ofand the moon," he told Space.com in an email."If it had not been for World War II and the subsequent Cold War, you could argue that mankind would still have not landed on the moon. In human history, need plays a dominant role in technology development speed. I do not have a good enough crystal ball to give a good answer.
