Three Stars Each (Civ6)

is the sixth challenge of the month in Civilization VI, running from April 9 to May 14, 2024.
This challenge returned as part of the called Three Stars Each Redux running from August 28 to September 4, 2024.
== Intro ==
The Babylonians were the first to record the cadence of the stars and planets in the sky. As Hammurabi, can you lead your people into space and secure a Science victory before May 14?
Technology and Civics trees are shuffled and hidden for this event, so Babylon's ability to unlock technological advancements via Eurekas is key. Adding to the unpredictability of this event, parameters including the map and other civilizations are randomized.
== Game parameters ==
* Difficulty: Prince / Emperor
* Victory: Science Only
* Speed: Quick
* Player Leader: 
* Map Type: Pangea
* Map Size: Standard
* RuleSet: Gathering Storm
* Start Era: Ancient
* Resources: Standard
* World Age: Standard
* Start Position: Standard
* Temperature: Standard
* Rainfall: Standard
* Sea Level: Standard
=== Redux parameters ===
* Babylon's ability applies to s as well as 
* Science and yields per pop are decreased by 99%
== Strategy ==
This challenge takes place on a random Pangaea map populated by random civilizations. The tech and civic trees are also randomized, which adds a great deal of unpredictability to the game. To achieve victory, you'll need to be familiar with the different leaders and their agendas so you can predict how they'll act and react. You'll also need to explore thoroughly and seek out Mountains and Reefs for bonuses.
The Babylonians' civilization ability cuts their output in half, but allows them to instantly discover a technology by triggering its . Since all victory conditions except Science Victory are disabled in this challenge, you'll want to slot Nuclear Espionage as soon as you unlock it and send your Spies on Steal Tech Boost missions so you can quickly discover Rocketry, Satellites, Nanotechnology, and Smart Materials. Once you've completed the Exoplanet Expedition project and launched your spacecraft, you just need to build Lagrange and Terrestrial Laser Stations to speed it along and send your Spies on Disrupt Rocketry missions to prevent your opponents from catching up to you. Alternatively, if you manage to secure some and build a strong enough military to defend yourself from attackers, you can launch nuclear weapons to shut down your opponents' Spaceports.
Note that building Flood Barriers in your cities will need to be a high priority in the later eras, because everyone will likely be too focused on developing Industrial Zones for and increased potential to worry about climate change.
=== Redux strategy ===
The -99% and per Population is misleading: it's actually -99% in all cities. This is devastating as it cripples nearly all sources of and and prevents discovering early techs and civics needed to obtain s. Mining, for example, doesn't have a , and you can't build the Mines needed to trigger the for Apprenticeship (which is critical for snowballing as Babylon) until you discover it.
In order to overcome this setback, obtaining percentage boosts to these yields ASAP is crucial. By getting or assigning Pingala to a city, you can reduce this penalty enough to obtain a little bit of or per turn and get the early technologies. Alternatively, pillaging a Campus or Theater Square could provide the initial you need. You can also look into other sources of and , such as Suzerain bonuses (especially those that provide lump-sum yields, like the ones from Ayutthaya and Fez), pantheons, religious beliefs, and . Note that some of those bonuses provide yields per turn to the city and still won't work.
