Making this table sortable 

Making this list sortable would add a lot of value: by longitude, by name, by country, launch date, etc. Unfortunately we can't simply apply the "sortable" attribute due to the hard-coded subdivisions. I recommend 1) moving the "In Transit" and "Historical" sections into separate table(s), 2) removing the hemisphere dividers, and 3) converting the longitude (Location) to signed notation, ie, replace E/W suffixes with +/- values. Making Location the default sort column would then result in the same hard-coded order that the table currently has.
