JWST - Cronostoria delle milestone nel corso degli anni

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:

2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020.
