April 27, 2026 18:21 - 19:46 Moscow Time
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. 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.

12-й полёт Falcon Heavy - уже скоро!
 Миссия ViaSat-3 F3 планируется к запуску 27 апреля в 17:21 МСК

В рамках этого полёта будут использованы боковые ускорители B1075 (22-й полёт) и B1072 (2-й полёт), а также новый центральный ускоритель B1098.

Посадки боковых ускорителей планируются на площадки LZ-2 и LZ-40 во Флориде, а центральный ускоритель полетит в расходуемом варианте.

Abrahamian noted that the time for on-orbit commissioning will be shorter than that of the Viasat-3 F2 satellite which flew on a United Launch Alliance Atlas 5 rocket. He said orbit raising to the operating position at the 158.55 degrees East position along the equator will take about two months.

"Falcon Heavy is a more powerful vehicle than Atlas 5 was, so they can put us in a more favorable transfer orbit for the electric propulsion," Abrahamian said. "So they're going to drop us off in an orbit, hopefully, that is just below [geostationary Earth orbit] apogee-wise, about 23,000 kilometers perigee-wise, and only about three degrees of inclination. So, it's a very [electric propulsion]-friendly orbit."

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.
