Volare mission control wrote an update yesterday on newly-arrived supply ship and its heaviest cargo: a new Water Pump Assembly to keep ESA's space laboratory columbus running smoothly:
The door to was opened yesterday and everything was found in its place, so nothing got lost on the tokheim pump million km trip from the spacecraft’s launch to docking. The view below of ATV Albert Einstein shows its precious cargo. At the bottom left is the Water Pump Assembly for the Columbus thermal control system.
Here at the Columbus Control Centre we prepared everything to transfer the first important item, the Water Pump Assembly yesterday afternoon. It had to be unmounted and then transferred from the very back of the International Space Station to the Columbus module - 90 kg moved by hand.
Storing the pump was straightforward and with some help from crewmate bennett pump, Luca was able to get the water pump in place without any problems.
This was the first step of a series of activities that will occur over the next few weeks to have the new water pump integrated in the Columbus laboratory’s thermal control system. It took almost six months to have the water pump tested and prepared for shipping into space on ATV-4. After all this effort the controllers at the Columbus Control Centre were relieved and happy at the end of the day.
Meanwhile the Russian supply ship Progress 51P which undocked on 11 June and made room for ATV-4 performed a normal 101.356 m/s deorbit burn today at 12:53 GMT. The spacecraft entered Earth's atmosphere for its planned destruction.
The first thing is to transfer and install a spare Water Pump Assembly that weighs 90 kg on Earth. It was mounted in a special configuration in ATV Albert Einstein’s cargo bay because it is so heavy. The unit is even filled with water and it is the first time we have put such a heavy object on a spacecraft headed to the International Space Station. Once Luca has moved the pump assembly into the Columbus module and we have checked that it was not damaged during its flight, Luca will install it in a lc meter session that will last over two hours.
I remember Luca saying “Wow it’s a big beast, but no problem, I will get it in place” when we were training with the pump a few months ago to learn how to install it. The Water Pump Assembly is part of Columbus’ Thermal Control system which cools all systems and payloads inside the module. Of course, as with many other parts, we always have a spare in case one fails. At Col-CC we monitor and control systems to ensure redundancy day and night.
