I had a momentary lapse last night - or was it inspiration? Anyway, I've added a real-time clock that shows the current time on Mars using the Martian clock (the seconds are a bit longer) for the location of the InSight lander.
This page is currently inactive for 2019 conjunction (until next conjunction in 2021)
Mars is heading for a solar conjunction, which in layman's terms means it's on the opposite side of the sun from the Earth. For a short period, no commands will be sent to the Mars spacecraft (which includes landers and rovers) since the sun's corona could corrupt those commands and result in unintended actions, disablement of the spacecraft or worse.
[Temperature over time] I've updated the format of the Temperature Over Time chart on the Mars Weather page to make it more readable. The sol numbers were overlapping each other, despite being broken into two rows. The chart is now interactive, in that you can use your mouse (or other pointing device) to select a position on one of the temperature graphs, and the sol number will be displayed at the bottom.
* Distances between stars (using start-chart coordinates) * Apparent magnitude of stars from other stars * Hohmann Transfer Orbits
Hohmann transfer orbits allow migration from a lower to a higher orbit or vice-versa. When used for interplanetary travel, these are solar orbits, but this kind of orbit can be used to move satellites to a higher altitude (or bring them back to a lower one).
Site Softwareplugin-autotooltip__default plugin-autotooltip_bigSite Software
Some people have expressed an interest in what software I use for this site. It's built around DokuWiki with some extensions to make it work like a blog, keep it transparent (all the articles and entries are visible in the treeview menu) and to spruce things up - such as the auto-tooltip which displays the first part of a page when the user mouses over an internal link (this also works in the top-bar menu). Some extensions make administering the site easier, such as moving articl…
Info Postsplugin-autotooltip__default plugin-autotooltip_bigInfo Posts
Posts in this section are informational only, and usually draw attention to an update in another page. Most often, these pages will be removed when similar information is added. For example, an update to Orbital Calculator effectively becomes stale when a newer update occurs, so the old reference is removed.
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.

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.
