The full Mon–Sun rotation
Each Colored Astronaut sits in a fixed weekday slot in Space Pack. Drop rate is 0.05% per pack for whichever color is active, but the off-day six are not in the pool at all, no chance of pulling them. The complete map:
- Monday → Pink Astronaut
- Tuesday → Yellow Astronaut
- Wednesday → Black Astronaut
- Thursday → Orange Astronaut
- Friday → Red Astronaut
- Saturday → Brown Astronaut
- Sunday → Green Astronaut
Why the rotation resets at 6 PM ET
Blooket runs the day flip on Eastern Time, not local time. A Blooket 'Friday' starts at 6:00 PM ET on Thursday and ends at 6:00 PM ET on Friday. If you live on the West Coast, that means the Friday rotation actually opens at 3:00 PM Pacific Time on Thursday afternoon, three hours earlier than your local Thursday-to-Friday boundary.
Practical consequence: if you want a specific color and you live outside ET, log the rotation in your time zone once and stick with it. Trying to open at midnight local time often lands you on the wrong day's color.
What the rotation does to chase math
All seven colors share the same 0.05% rate, so on the right day each one is a standard 0.05% Chroma chase, about 1,386 packs to a 50% cumulative chance. The wrinkle is the day-gate: if you only farm on weekends, you can only chase Brown (Sat) and Green (Sun) effectively. Targeting a weekday color while playing five days a week multiplies your real-world calendar time by 7/5, even though the math per opening is identical.
Stockpile tokens through the off-days, then open everything on the active weekday. That converts a 0.05% chase into one continuous block of attempts rather than seven scattered ones.
Astronauts that aren't in the rotation
Two extra Astronaut Chromas exist outside the weekday rotation. Cyan Astronaut was awarded to the top 10 of the Pokemon Are Cool event; Lime Astronaut went to the top 3 of the same event. Both are contest prizes, permanently unobtainable from any pack at any time of week.
Tim the Alien is a Mystical (not Chroma) reskin of the Space Pack's UFO. Same event lineage as Cyan/Lime, top finishers only, no day-of-week ever brings it into the pool. The colored slots Blue and Purple have never shipped, despite community speculation.
Frequently asked questions
What astronaut is available today in Blooket?
The current day's color depends on Eastern Time, not your local time. The map is Pink Monday, Yellow Tuesday, Black Wednesday, Orange Thursday, Red Friday, Brown Saturday, Green Sunday. The 6 PM ET reset means each weekday runs from 6 PM ET the previous evening to 6 PM ET that day.
Can I get any colored astronaut on any day?
No. Only the active day's color is in the drop pool. Opening Space Pack on a Friday cannot pull a Pink Astronaut, even by chance. The six off-day colors are removed from the rate table entirely until their day comes up.
When does the astronaut rotation reset?
6:00 PM Eastern Time daily. That converts to 3:00 PM Pacific, 5:00 PM Central, 6:00 PM Eastern, and 11:00 PM UTC. The reset shifts forward and backward across local-time midnight depending on your zone.
Why can't I get Blue or Purple Astronaut?
Blue and Purple Astronauts have never shipped as part of the Space Pack rotation. Only seven colors are in active rotation: Pink, Yellow, Black, Orange, Red, Brown, Green. Cyan and Lime exist as contest-only prizes outside the rotation.
Is the rotation the same on a Plus account?
Yes. Plus does not change drop rates, the rotation schedule, or pack contents. Every account sees the same color on the same day at the same time.
Does the rotation change for seasonal events?
No. The astronaut weekday rotation runs year-round and is independent of seasonal packs (Spooky, Autumn, Blizzard, Lovely, Lucky, Spring). Even when seasonal packs are live, Space Pack continues its normal Mon–Sun cycle.
