Viasat-3 F3 Mission
SpaceX is targeting Monday, April 27 for a Falcon Heavy launch of the ViaSat-3 F3 mission to geosynchronous transfer orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The 85-minute launch window opens at 10:21 a.m. ET. If needed, a backup opportunity is available Tuesday, April 28 during an 85-minute window that opens at 10:17 a.m. ET.
A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX (https://twitter.com/SpaceX). You can also watch the webcast on the X TV app.
One of the side boosters on this mission previously supported SDA-0A, SARah-2, Transporter-11, and 18 Starlink missions, and the second previously supported launch of the GOES-U mission. Following stage separation, Falcon Heavy's two side boosters will land on SpaceX's Landing Zones 2 and 40 (LZ-2 and LZ-40) at Cape Canaveral Space Force Station in Florida...

Хм-м, "18:21 - 19:46 Moscow Time" это 15:21 UTC
а не как у Лукаса и на сайте nextspaceflight.com "14:21 UTC"

Похоже, джаваскрипт на сайте СпейсХ некорректно обрабатывает таймзоны (точнее, летнее время): в UTC показывает 15:21, Лондон - 15:21 (должно быть BST - 16:21), Берлин - показывает 16:21 (должно быть 17:21, так же с учетом DST) и тд. Москва всегда +3 (без DST), поэтому 18:21 соответствует UTC 15:21.
НьюЙорк (EDT, не путать с EST) - UTC-4, EDT 10:21 -> UTC 14:21
edit: поскольку первично у них все-таки местное время, наверное, 14:21 UTC правильно.
