"Space is nasty and sending data across 83 light-minutes of it isn't easy"
Cassini has been sending data at a good speed across 83 light-minutes of space for years.
The distance and the space has not changed.
The fact that is now descending into Saturn's atmosphere has changed.
THAT is the problem for data speeds.
NOT 83 light-minutes of space.
Can't The Register find some science writers to write science ?
