Ariane 5 launch scrubbed by sensor problem (Reports)


Ariane 5 launch scrubbed by sensor problem (Reports).

An Ariane 5 rocket, operated by European Launch Service provider ArianeSpace, scrubbed ahead of its 109th scheduled flight, designated VA253.

The heavy lift rocket was scheduled to launch from pad Ensemble de Lancement Ariane 3 (ELA-3) at Europe’s spaceport in Kourou, French Guiana, at 21:30 UTC (17:30 EDT) on 31 July 2020. However, a hold was called – related to the Ground Support Equipment (GSE) under two minutes to launch. Efforts to return to the countdown within the launch window were unsuccessful, resulting in a scrub. A second attempt is planned on Saturday.

VA253 will mark the 253rd flight of an Ariane rocket since L-01, the first flight of the Ariane 1, on 24 December 1979.

The Ariane 5 rocket for today’s mission was integrated with its payloads earlier in July and rolled out to the pad, ELA-3, on Thursday, 30 July.

Three separate spacecraft comprise the dual-launch payload for this mission, including Galaxy 30, Mission Extension Vehicle-2, and BSAT-4b.

Riding in the “lower passenger” position inside the SYLDA (Système de Lancement Double Ariane — “Ariane Double-Launch System”) is BSAT-4b, a broadcasting satellite built by Space Systems/Loral (SSL), a subsidiary of Maxar Technologies. The satellite is based on the SSL-1300 spacecraft bus.

BSAT-4b is owned and operated by Broadcasting Satellite System Corporation (BSAT), which provides communication and broadcasting satellite services for Japan.
