Mysteries of the moon: what we have no idea after Apollo
We visited the moon half a century in the past and haven’t returned since. In the meantime, we launched a robotic spacecraft by our photo voltaic system and found distant worlds. In the meantime, scientists proceed to replicate on the rocky customer to our evening sky.
The Apollo missions have helped us remedy many mysteries of the moon, however there are nonetheless many unanswered questions – and even a pair ensuing from the samples reported by Apollo astronauts.
"Many scientific questions have emerged from Apollo's proof," mentioned Roger Launius, former chief historian of NASA, at Area.com. "There are lots of issues to be gained by going backwards, comparable to accumulating extra materials and accumulating new knowledge."

As NASA prepares to ship astronauts again to the moon by 2024, and confronted with conflicting messages from the US administration concerning the upcoming mission, scientists say the moon nonetheless has many secrets and techniques to discover.
"We’ve got lots of good questions," Sarah Noble, head of Apollo 's new technology pattern testing program at NASA headquarters in Washington, advised Area.com. "What has occurred over the previous decade is that now we have put lots of issues into orbit across the moon, which has given us an total image.
"We all know the place to go to reply these questions now," added Noble.
Almost 40 years after getting back from the moon, water was present in rock samples reported by the Apollo 15 mission. The 2009 discovery opened an entire new space of Moon analysis, suggesting that water may have existed on the Moon since its formation.
Having water on the moon is essential for future house exploration as a result of it may very well be used for ingesting water and rocket gas.
"For 40 years, we thought the samples had been fully dry," mentioned Noble. "We now perceive that there’s a cycle of water, however we don’t perceive the way it works."
We might not but perceive the water cycle, however now we have the instruments to interrupt it now.
"From my viewpoint, now we have every kind of devices that didn’t exist earlier than," Paul Hayne, an assistant professor within the Division of Astrophysics and Planetary Sciences on the College, advised Area.com. of Colorado.
Hayne added that the devices have grow to be so miniaturized that they match simply right into a spaceship.
Along with water, current proof additionally suggests that there’s ice on the moon. A research carried out in 2018 confirmed the presence of frozen substance on the bottom on the no
