Ho trovato un sito NASA in cui si tengono traccia dei progressi di JWST. Con un po’ di olio di gomito sono riuscito a formattare tutto abbastanza coerentemente con gli standard internazionali (ah, le date americane che incubo che sono). Manca solo la parte di traduzione degli eventi e delle note. Il post è wiki per chiunque voglia contribuire nella traduzione.
La legenda è la seguente:
- evento in verde: milestone raggiunta in anticipo;
- evento non evidenziato: milestone raggiunta secondo la schedule;
- evento in rosso: milestone raggiunta in ritardo;
- evento in arancione: milestone riprogrammata;
- evento in azzurro: milestone non inclusa nel programma.
Elenco degli anni:
