A cookie is a small file a site leaves in your browser so it can recognise the same visitor again. This page lists the ones we set and what each is for.
We use very few. They keep the site working properly and show us, in rough numbers, which pages people actually read when exploring our space adventures and planetary data.
Nothing here follows you across other sites, and we do not sell what the cookies record. There is no advertising cookie on this site.
If a page carries something served by another company, that company may set a cookie of its own. Their rules apply to it, not ours.
Every browser can block or delete cookies, usually under privacy settings. Blocking the necessary ones may stop parts of the site from working.
Clearing them removes anything already stored, and the site starts again as if you were new to it.
What we do with personal information more generally is set out separately.
If anything here changes we will update this page along with the date at the top.
Anything you are unsure about can go through the contact page, and we will answer plainly.
