EarthCARE out of the box

With the climate crisis increasingly tightening its grip, the Earth Cloud Aerosol and Radiation Explorer, or EarthCARE for short, carries a set of four state-of-the-art instruments that will work together to provide a holistic view of complex interplay between clouds, aerosols, incoming solar radiation and outgoing radiation to yield new insight into Earth’s radiation balance.

The EarthCARE satellite spent over a month cocooned in its transport container, during which the container’s temperature and pressure were monitored carefully throughout.

Importantly, the team also purged nitrogen from the container to keep the satellite’s instruments in perfect condition.

A NASA building near the Space X launch site in Vandenberg, California, was home for EarthCARE during the storage period. Then, a few days ago, the satellite container was taken by truck to a different facility, called the Astrotech building, where it was first left to acclimatise to its new surroundings.

But now, EarthCARE has now been carefully removed from the container, and the team has been reunited with their precious satellite.

ESA’s EarthCARE launch campaign manager, Bill Simpson, said, “EarthCARE’s journey to California and subsequent few weeks of storage all went really well, but we were anxious to actually lay eyes on the satellite again.

“So, when we were able to open the container and hoist EarthCARE out, we were all very excited. This hoisting manoeuvre is a very careful one – our satellite is over 2000 kg of very sensitive equipment.

“I’m extremely happy to report that EarthCARE looks fit and well, but we obviously have to run a series of tests to make absolutely sure that it survived the journey ok.”

One of the first tasks on the ‘launch campaign’ to-do list was to give the satellite some energy by charging up its batteries.

In parallel, the team at ESA’s Operations Centre in Germany is running a series of all-important simulations – these simulate what they will have to do during liftoff and the ‘early orbit’ phase of the mission.

ESA’s EarthCARE Project Manager, Dirk Bernaerts, noted, “This really does mark the start of the launch campaign – an important milestone that signals the start of an intense period that will last at least six weeks leading to liftoff.”

“The team has a lot of work to do, the satellite is not only big, but extremely complex so everything has to be carefully checked and prepared before it is encapsulated within its Falcon 9 rocket fairing prior to launch towards the end of May.
