Early in Jerry Pournelle's The Mercenary (London, 1977), there are references to:

Future History Background Details
Six Future Historians
Colonizable Planets?
Contrast Asimov's and Pournelle's sketchily described extra-solar planets with the details that Anderson provides about Hermes, Avalon, Dennitza, Aeneas etc.
For further discussion of this issue, see also:
Aldiss, Amis, Anderson, Asimov, Lewis
The question currently in my mind is not whether exo-planets have life but whether they have multi-cellular organisms.
See:
The Improbability Of Complex Organisms
The discussion is good even if not all the works discussed are.

Another Comparison
In Pournelle's CoDominium History, the US and the USSR become the CoDominium whereas, in James Blish's Cities In Flight, the USSR incorporates the US. In both these histories, life is bad on Earth but no one knows how to improve it - but some can escape out of the Solar System. The CoDominium is succeeded by Empires whereas, in Cities In Flight, the Bureaucratic State is succeeded by interstellar trade and peripheral empires although the trade is more important - as it is in Anderson's Polesotechnic League and Kith series.
Like sf in general, future histories are a dialogue.
Addendum: The CoDominium suppresses scientific research. In Cities In Flight, security stifles research.
Five Future Histories
How do these futures begin?
Heinlein: technological innovations on Earth and the first rocket to the Moon.
Anderson, Psychotechnic History: recovery from nuclear war and early application of psychotechnics.
Anderson, Technic History: exploration of Iapetus, Ythri and Avalon.
Niven: exploration of Mercury, Venus, Mars and Pluto.
Pournelle: use of a recently invented faster than light drive to forcibly relocate Welfare recipients to newly discovered extrasolar planets! (A down-to-Earth future, almost.)
The Chronology in Pournelle's The Mercenary (1977) covers the period, 1969-2060. The three parts of the book were originally published in 1971, 1972 and 1973. The "future" begins immediately after the publication date of any given story. Rereading The Mercenary in 2026, we notice that only four years in this Chronology remain in our future:

Details Of Interstellar Economics
The Peregrine, CHAPTER VI.
Solarians are economically self-sufficient and do not trade with the extra-solar colonies.
"A small but brisk trade went on between the stars of any given sector,..." (p. 38)
(Small, within each sector.)
"...carried by merchant ships or by such Nomads as weren't heading out into the depthless yonder." (ibid.)
(So some Nomads still do that.)
Despite the opening sentence of this post, some goods from Sol and other civilized systems reach the frontier where the need for spaceports, warehouses, depots, services, repairs, shops, factories, entertainment and administration means that there are cities although only one per planet or system: on Nerthus, Stellamont, the only physically realized extra-solar city in the Psychotechnic History.
Trevelyan Micah meets and (almost) "infiltrates" the Nomads of the Peregrine there.
Why An Interstellar Civilization Might Be Unstable
The Peregrine.
See:
Why Should An Interstellar Civilization Be Unstable?
We receive some answers.
The Shar of Barjaz-Kaui on Davenigo/Ettalume IV has started to tax traders. The Nomads cannot overthrow him by force because the Coordination Service knows of Davenigo. (Otherwise, the Nomads would have overthrown the Shar by force...?) Next best thing, the Nomad ship, Adventurer, and maybe also Bedouin, will try to subvert the Shar's government and to replace him with someone friendlier. If that is what some Nomads get up to, then no wonder the Cordies have to work overtime. And some Nomads have strayed a long way from their original "...undying voyage..." (CHAPTER II, p. 7)
Even more blatantly, the Stroller has sold guns to a race deemed unready for such technology and the Cordies have found out. Other Nomads do not condemn the Stroller but learn to watch their step with the Cordies for a while. Nomads are indeed disruptive.
More generally, Trevelyan Micah explains to Braganza Diane that:
human beings have visited a million stars and this number continually increases;
many visited stars have one or even more planets inhabited by intelligent beings with alien psychologies;
these beings' responses to an interstellar civilization are unpredictable and could be catastrophic.
The Cordies, unlike the Nomads, are concerned about the interests of all intelligent species.
