It's 2020 why can't nasa go to the moon with a gopro and take a picture of the earth? if they did it in the 60's they can for sure do it now.

Nasa has requested an increase in the 2020 budget of $1.6 billion, in order to make another crewed mission to the moon by 2024, followed by a sustained presence on the moon by 2028.

nasa has been discussing concepts for human lunar exploration since the apollo flights ended. in this 1995 artist’s concept, a lunar mining operation harvests oxygen from the lunar soil in mare serenatatis, a few kilometers from the apollo 17 landing site.

the apollo lunar flights may have ended in 1972, but the moon has remained of great interest to nasa and scientists around the world. “apollo” invariably stands near the top of all search queries on nasa’s public website. nasa has sent more than 500 apollo lunar samples in recent years to scientists around the world for ongoing analysis. each year a handful of new scientific papers offer insights and updates to what we’ve learned about the moon from these samples.

the program has even become a cultural benchmark. how many times have you heard someone ask, “if they can send a man to the moon, why can’t they . . “?

in the half-century since people visited the moon, nasa has continued to push the boundaries of knowledge to deliver on the promise of american ingenuity and leadership in space. and nasa will continue that work by moving forward to the moon with astronauts landing on the lunar south pole by 2024.

reasons:

not enough funding from the us government.nasa is actually developing new rockets, (ares i and ares v) for the return trip to the moon. these will be larger and taller than their apollo-era saturn counterparts, and will be able to carry more weight. during the 1960s, many americans felt the expense of apollo was justified because of its importance to national security during the cold war. today, some people question whether human space exploration is as valuable.
