After 50 years of leaving a few human footprints and a flag on Moon, NASA is planning to head back to the only cosmic body that humans have physically reached so far – but this time, they want to send humans to stay.

Jim Bridenstine, NASA administrator said that Donald Trump is planning to put Americans back to Moon after the epic Apollo mission, with the help of private space companies. NASA has already started asking the aerospace community to come up with designs for landers that can transport astronauts to moon. The primary goal is for American space agency is to develop and test out the spaceship for this mission by 2024 and use them to make a human comeback on moon by 2028.

The difference between the Apollo mission and the upcoming lunar mission however, is that “this time, when they go to Moon, they are actually going to stay”, and apparently this is not a mission meant to “leave flags and footprints and then come home to not go back for another 50 years”. This time, NASA wants to do it differently from all other countries, as this mission will be aimed to make space travel more sustainable and feasible for humans “to be able to come back and forth regularly”.

The last person to set a food on the Moon was Eugene Cernan in December 1972, during the Apollo 17 mission and now, if the deadlines set by NASA are followed, the next humans to walk on the lunar surface will be in 2028. The space agency is already inviting bids from the burgeoning private sector to build the probe, and the last date for bids is bids from the burgeoning private sector to build the probe. However, the challenge here would be to make it a stay worth staying.
