Ariane 5 | February 11, 2020
Flight VA252: Arianespace at the service of SKY Perfect JSAT (Japan) and KARI (Korea) with JCSAT-17 and GEO-KOMPSAT-2B.

For its third flight of 2020, Arianespace will orbit two telecommunications satellites using an Ariane 5 launch vehicle from the Guiana Space Center: JCSAT-17 for the Japanese operator SKY Perfect JSAT Corporation; and GEO-KOMPSAT-2B for Korea Aerospace Research Institute (KARI).



With this mission dedicated to space applications for telecommunications and environment monitoring, Arianespace once again contributes to the improvement of life on Earth.

Flight VA252 will be performed from Ariane Launch Complex No. 3 (ELA 3) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Friday, February 14, 2020 in Kourou to authorize the start of operations for the final countdown.

JCSAT-17 will be the 21st SKY Perfect JSAT satellite to be launched by Arianespace. This geostationary communications satellite will deliver flexible, high-bandwidth communications to users in Japan and the surrounding region.

JCSAT-17 payloads incorporates S-band, C-band and Ku-band transponders, which will provide satellite communication services. The S-band and C-band transponders will serve NTT DOCOMO, Inc., the largest telecommunications company in Japan, for its flexible mobile communications services in Japan and the surrounding region under IRU contract (Indefeasible Right of Use). SKY Perfect JSAT will support NTT DOCOMO's satellite communication services.

JCSAT-17 will also be the 32nd satellite launched by Arianespace for Japan.

Built by Lockheed Martin Space, JCSAT-17 will be the 47th satellite made by this manufacturer to be launched by Arianespace.

GEO-KOMPSAT-2B will be KARI's second satellite as a manufacturer – and its third as a client – to be launched by Arianespace.

The GEO-KOMPSAT-2 program is a national program of the Korean government to develop and operate two civilian geostationary satellites: GEO-KOMPSAT-2A for meteorological and space weather monitoring missions; and GEO-KOMPSAT-2B for Earth environment monitoring and ocean monitoring missions. The GEO-KOMPSAT 2 program also ensures the succession for the COMS program (Communication, Ocean and Meteorological Satellite).

The predecessor satellite, GEO-KOMPSAT-2A, was successfully launched by Arianespace in December 2018.

The satellite carries two main payloads: GOCI II (Geostationary Ocean Color Imager II), provided by Airbus Defence and Space; and the GEMS (Geostationary Environment Monitoring Spectrometer), provided by Ball Aerospace & Technologies.

GEO-KOMPSAT-2B will be the eighth satellite launched by Arianespace for South Korea.

Ariane 5 | February 12, 2020
Ariane 5 is assembled with JCSAT-17 and GEO-KOMPSAT-2B for Arianespace's upcoming heavy-lift launch

The Ariane 5 for Arianespace's next flight is now fully-assembled following the integration of its two satellite passengers – SKY Perfect JSAT Corporation's JCSAT-17 and GEO-KOMPSAT-2B for the Korea Aerospace Research Institute (KARI) – marking a key milestone in preparations for the February 18 mission to geostationary transfer orbit.


The completion of Ariane 5's assembly for Flight VA252 is shown during activity inside the Spaceport's Final Assembly Building. At left, GEO-KOMPSAT-2B is positioned atop the launcher, followed by the installation of JCSAT-17 (center and right), which is encapsulated in Ariane 5's protective payload fairing.

Encapsulated in the ogive-shaped protective fairing, JCSAT-17 has been positioned atop GEO-KOMPSAT-2B – which was installed on the launcher's cryogenic core stage during previous activity inside the Ariane 5 Final Assembly Building at the Spaceport in French Guiana.

These successive integration steps enable a new series of preparation milestones to begin. They include the launch readiness review on February 14, which is to be followed three days later by Ariane 5's rollout to the ELA-3 launch zone.

Liftoff is scheduled during a 1-hr., 2-min. launch window opening February 18 at 7:18 p.m. local time in French Guiana, with the two spacecraft to be deployed during a flight lasting 31 minutes.

Ariane 5 will deliver a total payload lift performance of more than 10,200 kg. during the mission – with this combined mass factoring in JCSAT-17 and GEO-KOMPSAT-2B, plus the launch vehicle's dual-passenger dispenser system and satellite integration hardware.

A dual-passenger delivery for Ariane 5

JCSAT-17 will be the 21st satellite for SKY Perfect JSAT to be launched by Arianespace. This geostationary-orbit communications platform is designed to deliver flexible, high-bandwidth communications for users in Japan and the surrounding region. Lockheed Martin produced the spacecraft using its LM 2100™ spacecraft bus.

GEO-KOMPSAT-2B will be operated as part of Korea's GEO-KOMPSAT-2 program, and is to perform Earth environment monitoring and ocean monitoring duties. This spacecraft was manufactured by the Korea Aerospace Research Institute (KARI), and will be the organization's second satellite as a manufacturer – and its third as a client – to be orbited by Arianespace.

February 18's mission is designated Flight VA252 in Arianespace's launcher family numbering system, signifying the 252nd use of an Ariane-series launch vehicle. The heavy-lift Ariane 5 launcher is delivered to Arianespace by ArianeGroup as the production prime contractor.

Ariane 5 | February 14, 2020
Launch readiness confirmed: Approval is given for Arianespace's Ariane 5 flight on February 18

Arianespace's dual-payload mission with satellites to serve Japan and South Korea – JCSAT-17 and GEO-KOMPSAT-2B, respectively – has been approved for next week's launch fr om the Spaceport in French Guiana.


Decals for Arianespace Flight VA252's two satellite passengers – GEO-KOMPSAT-2B (at left) and JCSAT-17 (center) – were installed on the launcher's payload fairing during activity inside the Spaceport's Ariane 5 Final Assembly Building (overview photo, at right).

The February 18 liftoff was authorized at the completion of today's launch readiness review, which confirmed the status of Ariane 5, its two passengers, the Spaceport's infrastructure, and a network of ground station's that will track the launcher's trajectory.

With this go-ahead, Ariane 5 will be transferred Monday (February 17) from the Spaceport's Final Assembly Building to the ELA-3 launch zone. This will position it for liftoff the following day during a launch window that opens at 7:18 p.m. and continues until 8:20 p.m. (local time in French Guiana).

Ariane 5 "by the numbers"

The upcoming mission is designated Flight VA252 in Arianespace's launcher family numbering system, notating the 252nd Ariane launch since this series of European-built vehicles began operation in 1979. ArianeGroup is the Ariane 5's production prime contractor.

Next week's mission also will mark the 108th launch of a heavy-lift Ariane 5 from French Guiana, wh ere the vehicle is operated alongside Arianespace's medium-lift Soyuz and lightweight Vega.

The sequence for launch success

Ariane 5 will deliver a lift performance of more than 10,200 kg. on the February 18 mission to geostationary transfer orbit (GTO). This total includes the JCSAT-17 and GEO-KOMPSAT-2B satellite passengers, and also factors in the launcher's dual-payload deployment system and integration hardware.

SKY Perfect JSAT Corporation's JCSAT-17 – produced by Lockheed Martin – will ride in the upper position of Ariane 5's payload arrangement, to be deployed first during the 31-min. flight sequence. It will deliver flexible, high-bandwidth communications for users in Japan and the surrounding region from an orbital position at 136 deg. East.

Located below JCSAT-17 in the launcher payload arrangement is GEO-KOMPSAT-2B, which was developed by the Korea Aerospace Research Institute (KARI). It was designed to conduct Earth environment monitoring and ocean monitoring missions, and will be stationed at the 128.2 deg. East orbital location.
