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.
Satellites offer such huge benefits, including communications, taking the internet where it wouldn't otherwise be feasible, monitoring our weather and sea-level changes, GPS etc. etc. We shouldn't forget spying (um, military intelligence) either, because despite its sordid nature, it is important. At least, some people think so.
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.
Getting To Marsplugin-autotooltip__default plugin-autotooltip_bigGetting To Mars
[Mars] Edit: updated to include
There are multiple ways to get to Mars, and each has pros and cons. The one thing they all have in common is orbital mechanics. Some options can get to Mars in a short period of time, while others could take up to a year. Some are better suited for robotic missions, others for crewed missions. This article takes a look at the problems of getting to Mars (and getting back) and what options are available.
[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 …
NASA recently won (14th-15th Sept 2019) two Emmy's for interactive content. Aside from the obvious achievements of winning the awards, there is something else going on here that should be recognised and encouraged. Awards, of course, are intended to recognise, encourage and promote excellence, but I'm talking about NASA not only reaching out to the public, but interactively engaging them.
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…
This is my blog. It is an eclectic mix of book reviews by new and up-and-coming authors, articles, science news, random topic monologues and stuff about my software. Sometimes I talk about my fiction writing too.

I needed to calculate orbital characteristics for any orbit around any gravitational mass (because I write sci-fi stories), so I wrote this program because I'm a programmer and I'm too lazy to do it by hand all the time. The program has expanded over the last few years, sometimes from suggestions by other writers. I make it freely available and as simple to use as possible. It now has a list of functions as long as your arm (assuming you're not a tentacle user), and the numbe…
