Encapsulated inside of the payload fairing is the ViaSat-3 F3 GEO communications satellite. Built by Boeing, the satellite weighs ~6,400kg, and has a massive unfurlable antenna. The satellite has a designed capacity of 1 Tbps, and will service the Asia-Pacific (APAC) region.

Thinking of Artemis II - I doubt I'll forget what it felt like to join the crew onboard #Integrity - I hope many will share their thoughts about the phenomenal #ArtemisII mission & crew. NASA/CSA/ESA really "Hit it out of the park" to use a baseball analogy. Thank you #Team - #NASA - #CSA - #ESA
