New IAU Star Names for D3-Celestial

As the IAU has recently approved a lot of official star names, so I updated d3-celestial to reflect these. Some are comletely new, others now have an officially approved spelling. I changed all those I previously spelled differently.

Here are those that have completely new names I didn't have before:

Space Observatories Update 01/2018

There were no new missions launched but with several telescopes entering planning and the usual delays it is time for an update to the Space Observatories page. Especially in the X-ray range the new appeaances in the list are IXPE, the Imaging X-Ray Polarimetry Explorer by NASA, the Indian XPoSat or X-ray Polariation Satellite, and the follow.on reimplementation of the Japanese ASTRO-H mission, ASTRO-H2 or XARM (X-ray Astronomy Recovery Mission)

The source data are now available on my space exploration history github repository, together with the included infographics.

Solar System Missions Update 01/2018

Here's my map of all active and future Solar System Missions as of January 1st 2018.

I know somebody is going to try to throw a car at Mars, but sorry, that dosn't count as "Space Eploration" in my book.

Data, images and documentation are available on my space exploration history GitHub repository and the associated website.

Solar System Missions Update 12/2017

Here's my map of all active and future Solar System Missions as of December 1st 2017.

No changes again this time apart from those mandated by the never ending dance of gravity...

D3-Celestial with constellation select

A new feature for the interactive d3-celestial map, center on and zoom in on a single constellation, and hilight the constellation boundary if they are displayed. Choose a constellation from the select-box below and see what happens.

I also gave all the configuration categories IDs, so it is pretty easy to simplify the form via CSS styles, #celestial-form #stars { display: none; } makes the setting for stars invisible, and so on. The available IDs are: general, location, stars, dsos, constellations, lines, and, other, or the respective categories. Above I hid all the categories except general with the css:

  #celestial-form #location, 
  #celestial-form #stars, 
  #celestial-form #dsos,
  #celestial-form #constellations, 
  #celestial-form #lines, 
  #celestial-form #other { display:none; }
