The Space Pack sits in the wider Blooket pack catalog alongside every other pack. The drop-rate math powering the calculator is documented in drop rates explained, and you can run the same probability engine for any chase across the game in the blooket calculator. Before committing tokens, cross-check the chase against the blook value guide and check whether the pack is currently featured on the pack release calendar.

Which Colored Astronaut is in the pool today?
One color per weekday. The pool flips at 6:00 PM Eastern Time, so a Blooket 'Friday' really runs from 6 PM ET Thursday to 6 PM ET Friday.
| Day (6 PM ET → 6 PM ET) | Astronaut | Drop rate |
|---|---|---|
| Monday |  Pink Astronaut | 0.05% |
| Tuesday |  Yellow Astronaut | 0.05% |
| Wednesday |  Black Astronaut | 0.05% |
| Thursday |  Orange Astronaut | 0.05% |
| Friday | Red Astronaut | 0.05% |
| Saturday |  Brown Astronaut | 0.05% |
| Sunday |  Green Astronaut | 0.05% |
Each color shares the 0.05% chroma slot, so opening on the wrong day cannot pull your target color. Plan the chase around the day you actually want, and bank tokens through the week if you only care about one color.

About Space Pack
Space Pack launched February 12, 2021, making it one of the older market packs still in active rotation. Its theme ties into Blooket's astronomy-inspired aesthetic, featuring planets, rockets, and, most distinctively, eight Astronaut Chromas that each correspond to a different colour.
Seven of the eight Astronaut Chromas are obtainable from the pack (the eighth, Tim the Alien, is off-pack and unobtainable from regular opening). Each available colour has a 0.05% individual drop rate, producing a combined 0.35% Chroma tier, the highest combined Chroma rate of any 20-token pack. Critically, only the Astronaut colour that is scheduled for the current day (the rotation resets at 6 PM ET daily) can be obtained. Red Astronaut rotates on Fridays.
Astronaut as a Legendary sits at 0.45%, putting it close to the Lion in Safari. The pack's Epic tier hosts stars and planet Blooks that fill out the theme. Five Common Blooks make up 74.7% of pulls, so most opens are low-value, but the Chroma ceiling is high.
Space Pack is one of the oldest market packs still in active rotation, which means its Blooks have been in the economy for years. That long supply history keeps Astronaut Legendary prices in the standard 60–150 token range despite the 0.45% drop rate. The day-gated Chroma system, however, creates artificial scarcity: because players can only collect a given colour on its assigned weekday, Chromas like Red Astronaut trade at premiums compared to packs where all Chromas are always available. The net result is a pack where the Legendary is common enough to resell routinely but specific Chromas remain genuinely scarce on the secondary market.
How to chase this pack
If you are chasing a specific colour, only open on the correct weekday, opening off-day burns tokens on Chromas you cannot receive. Red Astronaut (the most traded) drops on Fridays at 0.05%, meaning roughly 1,386 packs to 50% probability on the correct day. The combined Chroma rate of 0.35% still requires ~198 packs to cross 50% for any Chroma, an achievable medium-term goal at 20 tokens each (≈ 3,960 tokens). Astronaut Legendary at 0.45% is a softer target at ~154 packs to 50%.
