What this is
Arianespace is launching a rocket called Ariane 62 from Guiana Space Centre, French Guiana. The public listing does not name a cargo yet.
Arianespace is flying a Ariane 62 from Ariane Launch Area 4, Guiana Space Centre, French Guiana. Mission: ARIEL. Atmospheric Remote sensing Infrared Exoplanet Large survey mission (ARIEL) is an ESA telescope. During its 4-year mission, ARIEL will observe 1000 planets orbiting distant stars and make the first large-scale survey of the chemistry of exoplanet atmospheres. For a selected number of exoplanets, ARIEL will also perform a deep survey of their cloud systems and study seasonal and daily atmospheric variations. Planned orbit: Sun-Earth L2. Status: To Be Determined. Current date is a placeholder or rough estimation based on unreliable or interpreted sources. The published time can still slip. Rockets wait for weather, boats, and the range.

Too far to see
You will not see this rocket from Centennial, Colorado. It is about 4,007 miles east. The broadcast is the view.
That is too far for the flame and, for almost every launch, too far for the high-altitude plume. Dim the lights and watch together anyway. The clock is still loose, so daylight is a guess.
