In April, a privately spacecraft, named Beresheet, accidentally crashed into the lunar surface. It now appears possible that part of the payload of tardigrades might have survived the impact—and could still be alive on the Moon at this very moment.
Human beings landed on the Moon fifty years ago. While it's impressive that this feat still remains the high-water mark of human achievement all these decades later, the idea of putting humans back on the Moon within the next decade seems a bit underwhelming.
Mars is a bit of reach. It would be a huge undertaking—and an epic accomplishment—for our civilization if we're ever able to establish a human presence on the red planet. Despite the costs, there are a few reasons why it might be a good idea to start thinking about Mars more seriously.
Think about this: NASA currently spends billions of dollars each year on conducting scientific research on how living in microgravity effects biological organisms. The International Space Station has cost around $150 billion dollars to build and maintain, so far. But
Scientists have been trying to explain how life got started on Earth since Darwin upended biology over 150 years ago. This same question persists in planetary science today: we explore our Solar System largely because we want to figure out
It’s been 45 years since humans last stepped foot on the Moon and, in that time, no human being has even traveled beyond low-Earth orbit. NASA currently plans to resume human activities in deep-space in the 2020’s, though
