What will happen to MSG-3 in the next days after launch?

After the launch, a new phase called LEOP will start. LEOP stands for Launch Early Operation Phase. This phase will aim to put MSG-3 in its final configuration and orbit where it will be ready to perform its mission. It will last about 10 days will end with the MSG-3 handover to EUMETSAT (the operator of the spacecraft). LEOP will be continued by the commissioning phase.
Just after launch, some of our Thales colleagues from Kourou and Cannes will join now very rapidly ESOC in Darmstadt, the European Space Operation Center, where these LEOP activities will be performed together with ESA and EUMETSAT.

The next LEOP milestones are summarized below:
(Real status in RED, according to info from the LEOP team)
  •  Launch 05/07/2012 18:36 (Kourou) 23:36 (CET)
  • Launch T+ 34 minutes: MSG-3 separation from the launcher (Malindi tracking station acquisition); Successfully performed
  • T+ 4 hours, 1st spin up (55rpm): Successfully performed
  • T+37 hours, First Apogee Engine firing by LAM: Successfully performed
  • T+62 hours, Second Apogee Engine firing by LAM: Successfully performed
  • T+ 111 hours, third Apogee Engine firing by LAM: Successfully performed
  • T+134 hours, fourth Apogee Engine firing by LAM: Successfully performed
  • T+ 6 days and ca 8,5 hours, Spin axis erection* (1st part): Successfully performed
  • T+ 6 days and ca 14 hours, Spin axis erection* (2nd part): Successfully performed
  • T+ 8 days and 6 hours, (13/07/2012 @ 06:06 am CET), Cover cooler and SEVIRI baffle cover release: Successfully performed
  • T+ 8 days and 9 hours, (13/07/2012 @ 09:06 am CET), Spin up to 99.8 rpm: Successfully performed
  • T+ 8 days and 9,5 hours (13/07/2012 @ 9:36 am CET) Start of SEVIRI operations...: Successfully performed
  •  SEVIRI scan mechanism released, mirror moved from its launch position to a position in the the operational range: Successfully performed
  • T+ 9 days and 22 hours, Circularisation maneuver: Successfully performed
  • T+10 days and 9,5 hours (16/07/2012 @ 9:30am CET) Start of ESOC to EUMETSAT handover and end of the LEOP**: Successfully performed
*Up to that stage, the vertical axis of the spacecraft  (or spin axis) is within the orbital plane. The goal of the spin axis erection is to get it perpendicular to the orbital plane in order that the SEVIRI can "look" at Earth.

Successful Launch!

Few days ago on the Remire Montjoly beach, some of us saw baby turtles hatching from the eggs laid by the huge leatherback sea turtles last April. These three months of incubating period correspond exactly  to the duration of our MSG-3 launch campaign in French Guiana.

Like this small turtle entering the new sea world, MSG-3 enters, since the successful launch of this evening, its trip into deep space. For sure both need a bit of time and preparation before they become adults able to fully perform their respective missions. They will have to face multiple dangers and hostile environment...
As we wait for the first news coming from our "baby", let's wish them anyhow a good trip into their respective media and, on the top of that, a fascinating life!
Don't we say that turtles can live more than 100years? ... A good perspective for MSG :-)

Launch Day 05/07/2012

Follow MSG-3 launch live on ESA, Eumetsat or Arianespace websites.

07:15 am @ EPCU S5C North (Kourou time).  D - Day has started.
Let's start this message with an Arianespace picture taken yesterday (04/07/2012): the Launch vehicle on the ELA-3 Launch pad
Credits: Arianespace
09:36 am (L-9 hours) All Thales people in place at LBC-1. Countdown started. Spacecraft ON
An overall view of the LBC
A nice view on the launcher from the water tower (TV monitor in LBC-1)
11:24 am (L-7h 12mn). LBC-1 to Jupiter: MSG-3 status nominal
In the meantime, our mascot, Toco, joined the LBC-1...
12:26 (L-6h 10min). MSG-3 RF (Radio Frequency) Transmitter ON. On the background below the "RF corner" with Jean-Paul and Patrick (on the right). On the foreground all the Telemetry monitoring screens
13:25 (L-5h 11nin) All parameters are green. Few minutes later, 2 weather forecast reports: High winds and general weather forecast briefing. Green. Authorisation to fuel the Launch vehicle has been given.
14:21 (L-4h 15 min). MSG-3 started battery charging.

Getting prepared...

After so many efforts,  tomorrow will be "le grand soir" for MSG-3! So let's now get prepared.
Part of the MSG-3 team will be in LBC-1 room at EPCU S5 North in CSG. This LBC room, already introduced to the reader of this blog, contains all the EGSE (equipment bays) that are connected with the spacecraft. From there, all parameters related to the MSG-3 spacecraft are monitored and will be transmitted as needed to the Jupiter room (Control center) tomorrow during the count down.
Here above is an overall view of the LBC-1 rather empty this after noon. Below, Jean-Claude is testing a voice loop equipment to make sure that the communications with Jupiter work well. So no surprise tomorrow. During the countdown, he will act as RPS i.e. Resposable Préparation Satellite/Spacecraft Preparation Responsible.
Two monitor screens have been set in order that what is happening on the launch pad can be seen from LBC-1 . Tomorrow, a view of the Jupiter control room will also be available.
Everything looks fine. The last thing to think about is the dress code for tomorrow. Given instructions require white shirts for all. So the MSG-3 team members have still few hours to iron their launch crew gear in order to remove any unpleasant wrinkles or to pick up their laundry before 19:30 tonight at Georgette's laundry.
Finally, for those not in French Guiana, and interested to follow the launch, click here to reach the ESA web site which will broadcast the live video transmission of the VA 207 launch.
Eumetsat is also covering the launch from their website (click here).

MSG-3 on launch pad

1-On 03/07/2102 the VA 207 roll out started with roughly 1 hour and half delay due to the presence of some heavy clouds in the area of the transfer.
The distance between BAF and ELA-3 (Launch pad) is about 3 kilometers and the maximum speed of the convoy is 3 km/h.
2-The roll out was observed from the roof of the Galilee building. On the foreground the BIL (Batiment Intégration Lanceur/Launcher Integration Building) and just behind the BAF which is now familiar to the reader of the blog :-)
3-Roll out eventually started at 11:50 am (Kourou time). Here below VA 207 launcher between BIL and BAF.
4-Convoy crossing the main CSG road which had been closed to other traffic.
5- VA 207 convoy through the forest.
6-...getting closer to the ELA-3 launch pad.
7- Preparing for the last curve.
8- 13:25. VA 207 has almost reached the launch pad.
View again VA 206 roll out (taken within another angle of view at orchidée observation point).

Que le spectacle commence!

This morning, 03/7/2012 at 7:00 am  the doors of the BAF have been opened.

a close up view:
VA 207 is ready for the roll out to ELA-3 (Aire de Lancement#3 /Launch Pad#3)... if weather allows. The requirement is to have three hours free of thunderstorms to prevent the risk of lightening during the transfer (BAF to ELA-3).

Launch campaign status at L-3

No "visible" activities to report today as efforts concentrated on the launcher in the BAF and on the final preparation of the fairing (thermal and environmental controls, several inspections, red tag items, arming, closure...). These activities are exclusively under Arianespace responsibility without witnessing from the customer(s) side.
In the next days:
  • L-2 (03/07/2012) will be mainly dedicated to the RAL (Revue d'Aptitude au Lancement/Launch Readiness Review). An important review mainly focussed on the Ariane 5 ECA launcher.
  • L-1 (04/07/2012): Roll out of the launcher between the BAF and the ELA-3 (launch pad). This will terminate the quasi "secret phase" of the POC (Combined Operation Plan). This activity was already witnessed in May for the roll out of VA206 flight.
  • L0 (05/07/2012). Launch day. The countdown will start at 9:36 am (Kourou time) for a launch window starting 9 hours later.
Below, a picture of the CSG sky when we got out of our last meeting today 02/07/2012, looking in the direction of the ELA-3 launch pad. It gives a rough idea about the light we may have for the launch as it was exatly taken at the time corresponding to our launch window on next Thursday i.e. from 18:36 to 19:05 Kourou time or 23:36 to 00:05 Paris/Asterdam/Darmstadt time zone...
We are getting closer!
