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.
