A Major Milestone has been reached!
Written by [email protected]
12 November 2024
The team has excelled themselves in completing all the stand alone testing required in the SP-1B facility allowing for the transfer of the satellites to the SP-2B facility where the CSC satellite will undergo a fit check with the launcher payload adapter (PLA) prior to the start of the fuelling activities.
The satellites were packed ready to be loaded on the trucks.
The satellites arrived in SP-2B, were allowed to acclimatise overnight in the airlock and today had their lids removed to allow them to be pushed into the cleanroom.
The team then had a rest to gain energy for the fit check with the LVA
The CSC spacecraft was then lifted and moved over to be mounted on the LVA.
And then carefully lowered and mated on the LVA. The clampband holding the two together was then installed to ensure a perfect fit.
With the CSC spacecraft mated on the LVA the umbilical cables allowing the spacecraft to be monitored during fueling and launch were installed and tested to ensure they connected and, importantly, disconnected when the clampband opened and the satellite separated from the LVA.
With the checks completed the team was able to have some food and well earned rest.
The team also said farewell to some colleagues but welcomed others arriving today.

With the satellites tested and fit for flight the team from ArianeGroup are here to perform the propulsion activities starting with checking the the integrity of the subsystems and finishing with the hydrazine fueling of the CSC satellite.
Here you can see the setup and execution of the ongoing pressurization activities.
And once the pressure exceeded a certain safety limit extra protection was required by the team.
Under Pressure!!
The ArianeGroup fueling team have done an amazing job testing both satellites and filling the OSC with 268 bar of nitrogen for flight. The CSC was pressurised to MEOP to allow leak testing to be performed.
During the activities what we could see from the control room looked like a SWOT team had raided the facilities.
Leak testing has its challenges…..especially wearing a bullet proof vest and helmet!
Also, earlier in the day the two hydrazine drums were delivered to the facility for acclimatization in preparation for fueling.
Satellite Stacking
With the OSC being successfully fueled and the final preparation activities completed the satellites could be stacked as they are installed on the launcher already attached to one another and it is only during commissioning that the clampband holding the satellites together is released and they separate.
In preparation the upper cone from the CSC was removed and fitted to the vertical integration stand allowing the OSC to be lowered on to it and the clampband fitted.
The OSC, clampband and cone was then lifted and lowered onto the CSC where the cone and umbilicals could be installed and mated.
The stacked satellites were then transferred back to the vertical integration stand in preparation for the next important activity, the hydrazine fueling of the CSC, after which the satellites will be ready to be transferred to the launcher in SP3.
It was a long day for the team who did a remarkable job stacking the satellites. Now off back to the guest house for a well earned meal.
