        • A New Siteplugin-autotooltip__default plugin-autotooltip_bigA New Site

          Yup, the old site was as ugly as sin and to find a blog entry you had to scroll through the feed or take your chances with the search option.

          This new site is just as easy to maintain, has extensive search capabilities, and both orders and structures the entries. Not only does this make it easier for you to find stuff, it encourages you to browse around. It's not as ugly either.
        • How do I Calculate Distance from Period?plugin-autotooltip__default plugin-autotooltip_bigHow do I Calculate Distance from Period?

          I've been asked how Orbital Calculator can calculate the distance an object is from a gravitational mass, using just its period (the time it takes to complete an orbit). The technique is relatively simple, so I'll explain it.
        • A Keen Interest In Marsplugin-autotooltip__default plugin-autotooltip_bigA Keen Interest In Mars

          [MOLA globe of Mars]You may have noticed from pages such as the Mars Weather Report page, that I have a keen interest in Mars, Martian weather, and the InSight lander.

          Mars itself, and the incredible science we are doing there is of course a fascination in and of itself. However, my interest goes deeper than that. My latest novel (at the time this article was written - March 2019) is about the exploration of Mars. NASA have provided a wealth of data and information for …
        • Martian Spring Weirdnessplugin-autotooltip__default plugin-autotooltip_bigMartian Spring Weirdness

          [Mars (northern hemisphere)]Spring in the northern hemisphere of Mars is odd to say the least. The further the season moves away from winter, the warmer we should expect things to get, but this is not the case. It gets colder. By examining why, we can see why Earth is pretty much a special case, and begin to be able to predict weather patterns on other planets.

          [MOLA map of Mars coloured by elevation]

          Edited: 2019-03-14

          Sometimes when you do some research – actually, quite often – you find out some really interesting stuff and end up changing your mind. In my story, I had some people on the ground on Mars, and wanted a spacecraft in a geostationary orbit above them to give them communications between them at all times. Just for info, when talking about geostationary orbits, the accepted term for Mars is aerostationary. I’ll use g…
        • Orbital Calculator v1.0.0.5 Updateplugin-autotooltip__default plugin-autotooltip_bigOrbital Calculator v1.0.0.5 Update

          You can now calculate distance from a gravitational mass using the orbital period. The image above shows a calculation for Mars which has a 687 day year.

          I've allowed the use of tokens to identify time components to make it easy to use. The examples shown in the image should explain how it works.

  • Mars Weatherplugin-autotooltip__default plugin-autotooltip_bigDaily Mars Weather Reports

    These reports are provided by NASA's InSight lander in the south-west corner of Elysium Planitia.

    This page updates when it is refreshed. Daily readings are usually a couple of days behind reality (it takes time for the lander to transmit its data back to Earth).

    Orbital Calculator is the result of satisfying a need. There are online calculators for working out the orbital characteristics for satellites and spacecraft orbiting Earth, and they’re pretty cool gadgets as far as that goes, but quite limiting.
