 Ariane 5 is "go" for Arianespace's March 21 mission with SGDC and KOREASAT-7

 Arianespace's dual-payload mission to orbit telecommunications satellites for Brazil and South Korea has been given the go-ahead for a March 21 liftoff from the Spaceport in French Guiana, carrying the SGDC and KOREASAT-7 relay platforms.

The approval came at the completion of today's Launch Readiness Review, which confirmed the "go" status of Ariane 5, its two payloads, the Spaceport launch infrastructure and the network of flight trajectory tracking stations.

This confirmation followed the completion of Ariane 5's integration inside the Spaceport's Final Assembly Building, performed under the responsibility of Arianespace.

For its fourth launch of the year, and the second heavy-lift Ariane 5 mission in 2017, the two passengers were built by Thales Alenia Space – marking the seventh time Arianespace has performed a dual-payload flight with both satellites built by this spacecraft manufacturer.

 

A 10-metric-ton payload for Ariane 5

Next week's mission, designated Flight VA236 in Arianespace's launcher family numbering system, is scheduled during a launch window that opens at 5:31 p.m. on Tuesday afternoon – local time in Kourou, French Guiana – and extends to 8:20 p.m. (20:31-23:20, Universal Time, UTC).

The nominal duration of Flight VA236 from liftoff to separation of the satellites is 36 minutes, 46 seconds, with Ariane 5's total payload lift performance on this mission to geostationary transfer orbit estimated at approximately 10,289 kg.

SGDC is the mission's upper passenger and has a liftoff mass estimated at 5,735 kg., with KOREASAT-7 installed as the lower passenger with a mass at liftoff of approximately 3,680 kg.

Spacebus 4000-series platforms for both satellite payloads

Built with Thales Alenia Space's Spacebus 4000C4 platform, SGDC (Geostationary Satellite for Communications and Defense) is the first satellite that Arianespace is launching for Telebras S.A., performed within the framework of a contract with SGDC prime contractor VISIONA Tecnologia Espacial S.A.

Operating from an orbital position of 75 deg. West with Ka- and X-band transponders, the dual-use SGDC will provide sovereign and secure means for Brazilian government and defense strategic communications, as well as high-quality Internet services to 100 percent of the Brazilian territory as part of the National Broadband Plan.

KOREASAT-7 was produced using a Thales Alenia Space Spacebus 4000B2 platform, and will be the third KOREASAT satellite launched by Arianespace for ktsat – a wholly-owned subsidiary of KT Corp., which is the largest telecommunications/media service provider in South Korea.

Once positioned at 116 deg. East, KOREASAT-7 will provide a full range of video and data applications, including Internet access, direct-to-home broadcasting (DTH), government communications and connectivity for VSAT (Very Small Aperture Terminal) networks.  Its coverage area encompasses Korea, the Philippines, the Indochinese Peninsula, India and Indonesia.

Ariane 5                                                          March 20, 2017
 
Postponement of Ariane 5's rollout with SGDC and KOREASAT-7

 Today's scheduled transfer of the Ariane 5 launch vehicle from its Final Assembly Building to the ELA-3 launch zone has been delayed by 24 hours due to a social movement at the Spaceport in French Guiana. This activity will take place on March 21 if the situation permits.

As a result, Arianespace's Flight VA236 – which will deliver the SGDC and KOREASAT-7 satellites to geostationary transfer orbit – is now scheduled for liftoff on March 22 within the following launch window:
 

[/li]
• Between 4:31 p.m. and 7:20 p.m., Washington D.C. time
• Between 5:31 p.m. and 8:20 p.m., Kourou time in French Guiana
• Between 5:31 p.m. and 8:20 p.m., Brasilia time
• Between 20:31 and 23:20, Universal Time (UTC)
• Between 21:31 p.m. and 00:20 p.m., Paris time during the night of March 22 to 23
• Between 5:31 a.m. and 8:20 a.m., Seoul Time, South Korea, on March 23
  

The launch vehicle, as well as its SGDC and KOREASAT-7 satellite payloads, have been placed in a stand-by mode and are being maintained in fully safe conditions.

Due to a social movement, it was not possible to carry out today's scheduled transfer of the launch vehicle from the Spaceport's Final Assembly Building (BAF) to the launch zone. 
                         
As a result, Arianespace has decided to postpone the transfer by 24 hours, with operations resuming tomorrow, Tuesday, March 21, 2017, if the situation permits.

The launch vehicle, as well as its SGDC and KOREASAT-7 satellite payloads, have been placed in a stand-by mode and are being maintained in fully safe conditions.

Arianespace Flight VA236 – which is scheduled to launch SGDC for Telebras S.A., performed within the framework of a contract with SGDC prime contractor VISIONA Tecnologia Espacial S.A.; and KOREASAT-7 for ktsat – is now scheduled for:

Wednesday, March 22, 2017 as early as possible within the following launch window:

Ariane 5 launch pushed back to Wednesday by labor strikes in Kourou

A work stoppage at the Ariane 5 rocket's launch base in South America prevented rollout of the booster to the launch pad Monday, pushing back the liftoff of two communications satellites for Brazil and South Korea until at least Wednesday.

The fully-assembled launcher was set to roll out of the final assembly building Monday morning for the 1.7-mile (2.7-kilometer) journey to the ELA-3 launch zone at the Guiana Space Center. Arianespace officials were aiming for a launch attempt Tuesday evening.

But the rollout did not happen due to a "social movement" at the spaceport, according to Arianespace. Officials blamed the postponement on a strike among a segment of the workforce at the Guiana Space Center, which is managed by CNES, the French space agency, with support from the European Space Agency and numerous European contractors.

The space center is situated on the northeastern coast of South America near Kourou, French Guiana.

Labor issues at the spaceport have pushed back launches before, most recently in 2011 when the operators of radar tracking systems in French Guiana went on strike. It was not clear which workers were on strike Monday.

The rollout is now scheduled for Tuesday, officials said, with launch on Wednesday at 2031 GMT (4:31 p.m. EDT; 5:31 p.m. French Guiana time). The launch window extends until 2320 GMT (7:20 p.m. EDT).

Once at the launch pad, the rocket and its mobile platform will be connected to ground supplies of cryogenic propellant, power, and telemetry networks ahead of the final countdown Wednesday.

The launch will mark the second Ariane 5 flight of the year, and Arianespace's fourth launch of 2017. It will be the 92nd flight an Ariane 5 rocket since the heavy-lifted debuted in 1996.

Arianespace said the launcher and its two satellite payloads "have been placed in a stand-by mode and are being maintained in fully safe conditions."

Two communications satellites, named SGDC and Koreasat 7, are inside the Ariane 5 rocket's payload fairing awaiting launch.

SGDC will provide strategic communications for the Brazilian government and military services and beam broadband services across all of the country's territory to give Internet access to remote and under-served communities.

Koreasat 7, owned by South Korea's KTsat, will provide a range of video and data services over Korea, the Philippines, Southeast Asia, India and Indonesia.

Both satellites were manufactured by Thales Alenia Space of France.
