As I'm bound to have said many times before, my kids are big science geeks and are wildly excited about anything to do with space, so this is a freebie that I know they will love! NASA are sending a Solar Probe to the sun and you can have your name sent on it for free!
Anyone who wants to can have their name added to a microchip that will be on NASA's Parker Solar Probe as it flies on it's scientific mission to learn more about the sun and it's effects on Earth, so this could be a great opportunity to get more kids interested in science and space.
My boys already have their names on the OSIRIS-REx space probe on a mission to the asteroid Bennu, so this is another mission they will be able to follow.
There's lots more information about the mission and it's aims on the link above, and you have until 27th April to get names registered to be added to the space probe.
