The Space Station Is Becoming a Spy Satellite for Wildlife

The SciFi fan in me thinks we should shove a couple more up there to keep it company.

There is a lot of synergy from having a single large space station vs. many of small ones.
There are several helpful counterpoints to hand though. Two being the history Russian and Chinese space stations. All of them, including the Russian components of the ISS, have been vastly less expensive per module than the US components of ISS. Even if you factor in building and launching modules by US standards on US rockets it's still vastly less expensive than using the Shuttle.
Moreover, we've already seen that it's possible for US companies to deliver spacecraft to the ISS in the commercial cargo program. It would actually be just as easy to deliver components to the station using similar systems for about the same cost as a cargo launch today (around $150 mil at the high end). Over the roughly 2 dozen assembly flights for the Shuttle assembled side of the ISS that works out to an equivalent cost of about $4 billion, plus extra module construction costs. Keeping in mind that such flights have already been used or are being planned to use for adding modules to the ISS (such as BEAM and IDA).
Soyuz costs $62.7m/seat. [1] Which means that 8 seats to the ISS on soyuz is actually more expensive than a shuttle launch.
I couldn't find how much non-astronaut Soyuz payloads cost.
SpaceX's Falcon 9 Full Thrust can lift almost as much payload as the Shuttle, at 22,800kg.
I'm not sure how much each Falcon 9 launch to the ISS costs. Maybe someone else can chime in?

Sorry to be a stickler on this, but I like to use the ISS as an example of outrageously inefficient science, and so I'd like to make sure this isn't completely attributable to the cost of the shuttle (which, I think we agree, was it's own terrible boondoggle).
Arguably, without the ISS there probably wouldn't be any space stations. Stations were falling out of fashion by the 90s and even before were largely propagandist projects. The ISS was an attempt to turn all this wasted effort into something world usable (not just for the space faring powers of the time) and into something more science-centric. It was also an attempt to stop Russian militarization of space like mounting guns on stations (Salyut 3's 23mm cannon) or building more space battle platforms (Polyus). In fact, parts of the old Polyus system are now part of the Zarya module on the ISS. Seems like win-win for international cooperation, science, and peace.
I thought this was a pretty decent amount of info for a non-tech news source.

That one doesn't seem to be loading for me, but the Internet Archive has a version:

If their program proves successful they might be able to raise enough money to put hosted payloads on other spacecraft, one of the best being Iridium NEXT. But for now the ISS is their best shot.
