SpaceJelly

🚀 WHAT SPACEJELLY DOES

• Nearby launch discovery from trusted schedule data

• Twilight visibility score (0–100%) with clear labels: Prime, Good Chance, Marginal, Unlikely, or Invisible

• Plain-language "why this score?" breakdown (solar geometry, plume lighting, distance, clouds)

• Live countdown, weather context, and look direction (azimuth + elevation)

• Sky Guide compass to aim your phone at the plume

• Smart notifications when a launch meets your score threshold

• Home-screen widgets and Wear OS support so T-minus and score stay on your wrist

• Dark, night-sky UI built for outdoor evening use

OBSERVER-FOCUSED PREDICTIONS

SpaceJelly isn’t just a launch calendar. It combines:

• Your location and distance to the pad

• Launch timing vs local twilight

• Whether the plume is sunlit at altitude

• Trajectory and geometry calculations

• Cloud cover and visibility forecasts

You only get alerted when a visible twilight show is plausible—not for every daytime flight or scrub.

CUSTOMIZABLE ALERTS

• Score threshold (e.g., Good Chance and above)

• Alert timing options from 24 hours out down to T-0

• Scrub and NET time change updates

• Quiet hours support

PRIVACY & PERMISSIONS

• No account required

• Location used strictly for nearby launch distances and sky orientation
