I'm a novelist and have an interest in space science and physics. I've been a programmer for more than 30 years and I like reviewing new and up-and-coming authors.
If you want me to review your novel, please look at my page.

This is a minor enhancement to improve the efficiency and accuracy of the Two-Body calculations.
The “Two-Body” calculations try to take into consideration the effects of other bodies in the system, with a fallback to simple Newtonian/Keplerian mechanics. Deciding when to use the fallback algorithms and when not to is difficult, but the new code reflects statistical probability, which in turn increases accuracy.

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.
A bugfix and a new function has been added. Details are on thepage.
In addition, an import file is also available on thepage that contains 669 exoplanets with confirmed size and mass, culled from a NASA archive.
This lists the important notes on each new release, explaining what has changed and what's new.

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.
