Two well written, well received questions each with several well written, well received answers. Each now has one close vote as a duplicate of the other.
- January 2019 Why are probes that tend to explore outer system always launched to go outwards instead of straight upwards or downwards? Q: +28, top A: +50, +36, +28, +5...
- September 2013 Is there any reason to send space probes along the plane of our solar system instead of perpendicular to the plane of our solar system? Q: +10, top A: +13, +9, +5, +4...
The 2019 posts probably have more absolute votes because of higher readership in 2019 than in 2013.
Can anyone see enough difference between the two so that they should both remain open? Is this a good candidate for merging to keep all good answers on an equal footing, or should one be closed?
If the latter, then is there a way to decide which should be closed as duplicate of the other? I think that the order in which they appear to close-voters will determine this and that's not necessarily the best method.
