There was some discussion earlier of a Somalian cosmonaut flying as part of the Intercosmos program, and as someone who knows a bit about the Soviet space program and can interpret Wikipedia usefully, I thought I might offer some advice about how that might come about. If you go look into the Intercosmos program's selections, you'll see that, basically, there were two "regular" selections of a number of cosmonauts from Communist countries, in 1976 and 1978, and then three "groups" that each consisted of two cosmonaut candidates from individual countries, which (given the state of the Soviet economy at the time and later events) makes me rather suspect that they were flown into space thanks to some kind of high-level deal between the Soviet and foreign governments. I know that this was certainly the case for Chrétin and Sharma, at least.
Now, it's conceivable that Somalia could make some kind of arrangement to fly a cosmonaut on a mission along similar lines to France or India, but I suspect that working through "regular" lines would probably work better for them, if for no other reason than it would be more likely that the Soviets would be trying to woo them than the other way around. Now, the first, 1976, selection only consisted of six cosmonauts from European countries, but the 1978 selection also included cosmonauts from Mongolia and Cuba, in an obvious effort to spread the geographical base a bit, and therefore if any African country was going to have cosmonauts selected into the Intercosmos program outside of a country-specific opportunity, it was going to be in 1978. As far as Somalia is concerned, though, this was a bit of a problem, for reasons you can doubtlessly see right away: when the cosmonauts were selected at the beginning of March, the Ogaden War was still raging, and, even worse, the Soviets had thrown their lot in with the Ethiopians. So neither the Ethiopians nor the Somalians were inclined or particularly able to run through the process of getting a cosmonaut selected, and anyway the latter were decidedly on the outs with the Soviets. However, if the Ogaden situation is resolved earlier, say in 1976 or early 1977, and the Soviets align towards Somalia instead of Ethiopia, then there is certainly a chance that Somalia can be part of the 1978 selection if it wants to.
So my recommendation is that two Somalian cosmonauts are selected to join the Intercosmos program in 1978 to represent Africa, as Mongolia represented Asia and Cuba represented the Americas. One of these cosmonauts is then launched either on Salyut 7 EP-2 (in 1982) or Salyut 7 EP-4 (in 1984), bumping Svetlana Savitskaya in either case (the Soviet space program was and remains notoriously misogynistic, so she's almost certainly going to be first on the chopping block). I favor the 1982 launch opportunity because it gives the Soviets the opportunity to boast about how they've launched African cosmonauts before the United States has--granted, they had that to some extent IOTL thanks to Arnaldo Méndez, but being of African descent is different, in propaganda terms, from being African or African-American. I'm not sure if Guion Bluford's flight on STS-8 was scheduled yet at that point, since STS-8 underwent a significant manifest change in May 1983 that may have put him on the crew list, but in any event NASA and the United States Air Force had inducted Bluford, Bolden, and other African-American astronauts in 1978, 1980, and 1982, so a flight of an African-American was obviously coming sooner or later, and by flying a Somalian in 1982 the Soviets can get out in front and win the propaganda thunder.
Most likely there is not another Somalian cosmonaut flight up to the present day, but I could see Somalia developing a satellite industry of some sort, most likely as a satellite operator than a satellite builder (lots of people have done that, there's a lower technical bar to entry). There would be obvious advantages to deploying satellites for communications purposes, particularly television distribution, for Somalia and the whole Horn and East African regions, and the cost barrier is comparatively low. Observation satellites might also be of some value for land-use investigation and similar purposes, but I suspect Somalia is more likely to arrange to acquire imagery from commercial or public sources than build its own observation satellite(s) due to their technical complexity and the difficulty of importing relevant technology due to their dual-purpose nature (another word for observation is spying...). It might be useful to look at the Indian space program for inspiration, since their general situation would likely be similar to Somalia in broad terms due to both countries being developing states. Of course, you have to factor in that India is much bigger and so had more resources in absolute terms even at similar relative levels of wealth, so Somalia is likely to have a less ambitious program. Launch, in particular, is not likely to be pursued by the Somalis nearly as quickly as it was by the Indians, since it's less strategically useful to them and it's also one of the hardest and most expensive parts of the enterprise.
