NASA hopes to send astronauts to Mars by the 2030s in whatβs set to be the most exciting space mission since Neil Armstrong touched down on the moon.
Lasting around seven months, the 250 million mile journey will require the development of a new generation of deep space crafts.
The space agency has partnered with six companies to develop vehicles that could take astronauts further into space than ever before.
Boeing, one of NASAβs partners, has now unveiled concepts for both its deep space gateway and deep space transport vehicle.
The former would provided a habitat for astronauts in between Earth and the moon and a waypoint for missions to Mars.
Like the International Space Station, the gateway is designed to host a docking station for other crafts, such as the transport vehicle.
The craft would take astronauts all the way to Mars, but a lander would be deployed for the final descent.
Aside from the designs themselves, Boeing has skimped on detail about the crafts, beyond revealing they leverage solar electric propulsion technology.
But given the timelines involved, it shouldnβt be too long till we found out more.
Pete McGrath, marketing chief for Boeingβs space exploration division, said: βThe ability to simultaneously launch humans and cargo on SLS would allow us to assemble the gateway in four launches in the early 2020s.β
