Day 1 - Spaceship Generator with Deck Maps at Role Generator
Starting with the Random Spaceship Generator at Role Generator, which has a deck map different sizes of ships and lots of detail. There's a filter for spaceship type too.
Role Generator has many other generators, including a few more for Science Fiction.
Day 2 - Sectors without Number, System Map Generator
Sectors without Number is a system map generator (mine has 16 systems) based on tables from the RPG Stars without Number. The tool has lots of utility, and can be configured with Name, size in hexes and what to show to players in the Player's View.
The maps have information on systems, black holes, planets, asteroids, factions and other entities. Maps can be edited, saved and exported.
Day 3 - GameMaster's Apprentice Cards: Sci-Fi & Cyberpunk
GameMaster's Apprentice are a deck of cards with all sorts of information on each card to help with GMing or solo gaming. Dice rolls, oracle results, locations, names, atmosphere descriptions, symbols, action/focus/theme words among others.
The first relevant one is GameMaster's Apprentice: Sci Fi (drivethrurpg link), dedicated to Science Fiction themes! (I got the pdf and printed out the cards, sleeving in magic-card protectors for my Scum & Villainy solo game)
The second sci-fi related one is GMA 2e - Cyberpunk, with a slightly different layout and focus for dystopian futures. (I think plan is to eventually update other decks to a 2e version)
Day 4 - Five Parsecs from Home
Five Parsecs from Home is a solo miniatures skirmish game, driven by random tables.
It describes itself as a "rpg-lite solo adventure wargame" and consists of two main parts. The campaign section where you're looking for jobs, keeping an eye on threats, trading, recruiting and travelling the galaxy.
Then there's the battle part, where you're battling foes using miniatures. (I might try it on a Virtual Table Top like roll20)
There's several expansions, a fantasy version (5 Leagues from the Borderlands), a r/5Parsecs subreddit and an actual play by Trevor Duvall on Me, Myself and Die (also available in podcast form)
Day 5 - World and Planet Generation Tools
Unique planets, homeworlds, dead planets, city-worlds, crash-landing worlds, all important for sci-fi games.
A few tools for planets (whole systems is another day) include
- The SciFi World Generator at donjon, creating a map and details of a world (with several filters)
- For a text version Fantasy Name Generators has a Planet Description Generator, giving a few paragraphs.
- At RanGen there's a Planet Generator which gives lots of details, including a filter for scientific names
- Iron Arachne has a Planet Generator with info including terrain highlights, government and culture

- For (paid) random tables Ennead games has a Star System and Planet Maker (drivethrurpg link)
Day 6 - Vintage Star System Map Generator
Something a little different is the Vintage Star System Generator by Arkimedz at Itch.io.
Crammed in at the bottom is information about the system and the planets within.
A great example of a random generator that's a little different, combing style and utility. It could make a good handout to give to players or to use in a solo game.
Ironsworn: Starforged, RPG with many Random Tables
Starforged by Shawn Tomkin (drivethrurpg link) is a science fiction roleplaying supported and driven by many random tables. It can be played solo, co-op or with a Gamesmaster.
It's built on the same system as Ironsworn, where you're swearing and fulfilling iron vows to drive forward the story. Each roll will advance the narrative/state in some way (miss has consequences, weak hit has good stuff + consequences, strong hit has good stuff).
Tools to help play the game include Stargazer (online campaign journal / reference) and there's a collection of Starforged Oracles at Chartopia.
Podcasts actual plays for Ironsworn: Starforged, include Errant Adventures - Season 1 (the first actual play podcast I got heavily into) and the Bad Spot (also available as YouTube videos).
Day 8 - Sidequest Decks: Science Fiction from Inkwell Ideas
Decks of cards with quest ideas are good for GMing, solo and inspiration.
Sidequest Decks: Science Fiction is a deck of 55 cards, each with a sidequest / plot hook, with a map on the back. Part of a series of Sidequest Decks (Science Fantasy and Modern)
Available as a deck of cards or a PDF (I often get PDFs of cards, print them off, cut out and put them in card-protectors used for magic cards)
Day 9 - Alien and Lifeforms Generators
Aliens to meet, strange creatures to populate new worlds, monsters to threaten ships and crew...
- The Species Generator at RanGen has an appearance, stats and family life notes. Filters include form, size and class (mammal / fish / invertebrate etc)
- Role Generator has a great Alien Species Random Generator with many details and a filter for type
- Ennead Games has a paid pdf - the Lifeform Maker (drivethrurpg) with many tables for customising and creating alien life forms.

- 7th Sanctum has an Alien Race Generator with a wide range of odd results.
- There's a Fantasy & Sci-Fi Race Generator for humanoid-like aliens at springhole
- The Alien Species / Race Generator at SciFi Ideas gives a name and basic description of 5 species at a time
Day 10 - Stars Without Number
Stars Without Number (SWN) ticks (or checks) the boxes of Sci-Fi, Random Tables and Free (with a paid version too).
An RPG by Sine Nomine Publishing, Stars Without Number (Revised. drivethru link) is available free. It has many random tables that can be used for any game, is compatible with old school adventures and has companion RPGs in other genres to mix in with (Worlds without Number for fantasy, Cities without Number for cyberpunk and another on the way).
The paid version of Stars Without Number has extra content and random tables.
A few generators have been made using SWN tables, including Day 2 (Sectors Without Number), a Collection of SNW tables at Chartopia and the SWN Sector Generator at Emichron (nice tabbed version)
Day 11 - Glide, A Solo/Co-op RPG Inspired by Dune
Today's is a bit different, with the rpg Glide (itch.io) by Sasquatch Games. It's playable in solo or in co-op mode and inspired by the world of Dune.
You're "exploring a desert planet for scrap left behind by the Great Houses of before"
Lots of ways to play it and looks like it's on sale (at itch) til end of April.
Day 12 - Star Wars Tools

Mothership is a Sci-Fi Game Horror from Tuesday Knight Days with pay-what-you-want core rules - Player's Survival Guide (drivethrurpg). There's also free resources & downloads on the company site (and the free rules there too)
The rules are straightforward and there's random chargen for quick starts. The magic of Mothership is in the supporting modules such as A Pound of Flesh and Hull Breach (both from TKG) and Hundreds: Essential d100 Tables for Mothership & Sci-Fi RPGs.
There's also a strong community (including a r/mothershiprpg subreddit), including many random tables such as this Mothership d10 Tables collection from Chartopia.
It's also a strong choice for solo play and one option is a blog with some notes on Solo and Wardenless Play.

Spaceships generators split into Ship Gens, Spaceship Maps/Models and Spooky Ships
Ship Generators

Day 21 - Traveller RPG and Tools
If there's an original RPG associated with generators and procedures, it's probably Traveller (first published 1977). It's a sci-fi game using 2d6 for tests, that can handle several different types of sci-fi with lots of supplements and support. It's also infamous for characters being able to die in character generation!
Mongoose (drivethrrpg link) is the current publisher, with 2 editions. The original version of Traveller is currently available as a Free pdf from Game Designer's Workshop (softcover also available)
There's a few tools around too

Day 23 - Entity - Hard Sci-Fi Exploration Solo RPG
Entity by Candlenaut (drivethrurpg link) is a 24-page solo rpg where you play an AI Synthetic Astronaut . It's hard sci-fi (as in realistic, not as in a difficult RPG),

There's also an expansion with more options (Entity - Advanced Storytelling)
