Terms of service

Read it before the asteroid does.

These terms are written for fun. The important parts, that we are not NASA and that you should not use a comedy website to defend the planet, are completely serious.

The agreement

By using Rock Dodger you agree to these terms. If a large rock stops you from agreeing to them, they will apply retroactively.

We are not NASA

Rock Dodger is an independent project. It is not affiliated with, endorsed by, sponsored by or in partnership with NASA, ESA, JAXA or any other space agency. We use NASA's public Near Earth Object Web Service, the same free data anyone can use. NASA does not know we exist, has not approved anything we say, and should not be contacted about our jokes.

This is not a planetary defence system

If a real asteroid is heading for you, the authorities will tell you, and they will not do it with a page that compares rocks to wheels of Gouda. Do not use this site to make decisions about your safety, your travel plans, or whether to cancel your meeting. For official information about near-Earth objects, go to the space agencies themselves.

Accuracy

The numbers come from NASA and our arithmetic on top of them, and we check our work. The estimates (size, mass, impact energy) are estimates, and say so. The comparisons (bananas, elephants, football pitches, trains) are comparisons, not measurements. Nothing here is advice of any kind, including the advice to finish your tea.

What we are responsible for

Typos. We accept full responsibility for typos. We do not accept responsibility for impacts, near misses, tidal waves, extinction events, delays, existential dread or being late to meetings, whether or not an asteroid was involved.

Who owns what

The commentary, design and code on this site are © Cultured Digital. NASA's data belongs to NASA to publish. Films, film titles, trademarks and the videos on our Rocks on screen page belong to their owners and to YouTube, and we claim no rights in any of them. We link to and embed them because they are interesting, and we would take them down on request.

Other people's websites

We link to other sites and share buttons. We are not responsible for what is on the other end, and not many of them have a sense of humour.

Changes

We may change these terms whenever we like, usually when the asteroids do.

The law

These terms are governed by the laws of England and Wales and, where those fall silent, by the laws of orbital mechanics. This is a joke on a comedy site and not legal advice. For a real contract, find a real solicitor.
