Nasa admits it can’t afford to land humans on Mars

Nasa has announced it can’t afford to land humans on Mars.

The space agency has discussed plans for landing people on the red planet for some time, but it doesn’t look possible right now.

While it may still be able to fly astronauts to Mars, entry and landing is an entirely different matter.

“I can’t put a date on humans on Mars, and the reason really is... at the budget levels we described, this roughly two percent increase, we don’t have the surface systems available for Mars,” said William Gerstenmaier, Nasa’s chief of human spaceflight, this week, Ars Technica reports.

“And that entry, descent, and landing is a huge challenge for us for Mars.”

The Space Launch System and Orion spacecraft, which were expected to make a future Mars landing possible, have been expensive to build.

As a result, Nasa hasn’t even been able to start designing the vehicles that would land on Mars or ascend from the planet’s surface.

Private companies, such as SpaceX and Blue Origin, are also planning Mars landing missions, and won’t be restricted by the same financial constraints that are holding Nasa back.

Elon Musk wants to establish a colony on Mars, and is aiming to land humans on the planet in 2025.

Nasa, meanwhile, has opened the door to future Moon missions.

“If we find out there’s water on the Moon, and we want to do more extensive operations on the Moon to go explore that, we have the ability with Deep Space Gateway to support an extensive Moon surface program,” Mr Gerstenmaier continued.

“If we want to stay focused more toward Mars we can keep that.”
