Deep Space Exploration
The last time humanity visited the Moon was during NASA's Apollo 17 mission in
December 1972. This mission marked the end of the Apollo lunar program and the
sixth successful crewed Moon landing. Since then, the experience gained from Apollo
has laid the groundwork for modern space exploration. Technologies developed for
these missions, such as spacecraft design, life support systems, and navigation,
have been adapted for deeper space exploration. This foundation has enabled new
endeavors like the Artemis program, aiming to return humans to the Moon, and has
spurred robotic missions to Mars and beyond, pushing the boundaries of our
understanding of the cosmos. The NASA program is currently working alogside
other programs such as SpaceX to further explore
the endless expanses above us.
