There are more options to send a satellite.
The U. K. Skyrora (https://www.skyrora.com/) has three stage rockets to send a satellite to the orbit. It is able to perform maneuvering while reaching the target, escaping debris and facilities that are already there.
I wonder, if ever it will be possible to send caches there with signaling to the Earth, so that it can be found and logged with the signal.
