Go Caution No-Go

Will it launch? Independent weather verdicts for every rocket launch

Q: How is the GO / CAUTION / NO-GO verdict calculated?

Each launch starts at 100 points and loses points for sustained wind (from 18 knots), gusts (from 40 knots), cloud cover (from 60%), chance of precipitation (from 30%) and thunderstorm energy (CAPE from 1,000 J/kg) at the pad at the launch hour. 75-100 is GO, 50-74 is CAUTION, below 50 is NO-GO.

Q: Is this the official launch go/no-go?

No. Official launch commit criteria are vehicle- and range-specific and not public. Rocket Assessor is an independent, indicative weather assessment.

ALL SIGNAL · ZERO NOISE

Flightradar24 for rocket launches, with an honest weather go/no-go for every pad. Rocket Assessor tracks every scheduled orbital launch on Earth and gives each one an independent weather verdict for its launch pad: GO, CAUTION or NO-GO, with a 0–100 score and the reasons. It refreshes every 10 minutes and is not affiliated with any launch provider or range.

How is the GO / CAUTION / NO-GO verdict calculated?

Each launch starts at 100 points and loses points for the forecast at the pad at the launch hour:

Factor	Starts costing points at	Largest deduction
Sustained wind	18 knots	−45 at 35 knots and above
Gusts	40 knots	−15
Cloud cover	60%	−18 at 85% and above
Chance of precipitation	30%	−25 at 60% and above
Thunderstorm energy (CAPE)	1,000 J/kg	−30 at 2,000 J/kg and above

75–100 is GO, 50–74 is CAUTION, below 50 is NO-GO. Launches more than 16 days away show PENDING until a forecast exists. Schedule data comes from Launch Library 2; forecasts from Open-Meteo.

How accurate is Rocket Assessor?

Every verdict is frozen 24 hours before launch and scored against what actually happened. As of 19 October 2026, 71 launches had resolved and 36 of 54 directional verdicts (GO or NO-GO) matched the outcome (67%).
