Looking at the Moon, it looks bone dry, but it turns out scientists discovered this isn't the case. Tara Hayden, @MiniMoonRocks, wrote a great article for @OUFreeLearning about the legacy of the Apollo missions, including the search for Moon water.… Looking into the future, if we want to send humans to live on the Moon, they'll need water and it's too expensive to launch from Earth. So maybe they could use the water inside the Moon instead?

This article by @simeonbarber looks at this topic.…

For this thread, we’re diving into to some Moon basics. You might be wondering what the Moon is made from 🤔 We can tell you it’s not cheese! 😂 This @OUFreeLearning will get you up to speed about the rock minerals inside the Moon. #LivingOnTheMoon… Here’s a neat video featuring Professor in Planetary Science and Exploration, @ma235camb, explaining more about his research on Moon rocks within @OU_SPS.

We continue our #AsteroidDay content and, looking to the future, Prof of Planetary and Space Science, Simon Green is working on space missions that will visit asteroids in coming years.

Why? For planetary defence - how we protect Earth from impact by space rocks in the future. One of the planetary defence missions is @NASA's DART and the other is @esa’s HERA, both looking at how to deflect asteroids on a collision course with Earth. @ESA have a great video narrated by @DrBrianMay all about how these missions are connected.

Today we’re posting asteroid content to celebrate #AsteroidDay.

In case you missed it this morning, @ESA made a programme as part of @AsteroidDay, which included @StarkeyStardust as a guest. It’s a good place to start on your @AsteroidDay journey.

Another key aspect of asteroid science is in figuring out the danger they pose to life on Earth. The poor dinosaurs owe their demise to a large space rock colliding with our planet but in this article, @monicaGrady discusses what small asteroids could do.…

To mark #AsteroidDay, we’ve got a whole day of #asteroid content ready for you. Stay on board to learn how and why we study asteroids with spacecraft, and how we protect Earth from them colliding with us. We'll even look at #SpaceMining! #AsteroidDay was founded by astrophysicist @DrBrianMay, Astronaut Rusty Schweickart Filmmaker @GrigRichters; and B612 President Danica Remy, to encourage the public and governments to learn more about asteroids and the role they play in our Solar System.
