HUMANS have already reached the Moon – and Mars seems like the obvious next step.
But how will we get there? There are several mega-rockets already being developed that could take us to the red planet.
ars is far away – around 140 millions from Earth on average.
That means getting there is not only time-consuming, but very expensive in terms of fuel.
Nasa hopes that one way of bringing the time and cost down is using nuclear propulsion.
"Nasa’s goal is to minimize the time the crew travels between Earth and Mars to as close to two years as is practical," Nasa said in 2021.
"Space nuclear propulsion systems could enable shorter total mission times and provide enhanced flexibility and efficiency for mission designers."
In 2023, Nasa revealed that it had teamed up with Darpa (Defense Advanced Research Projects Agency) on building such a rocket.
And it said that this would allow for speedy trips to Mars and back.
