Not to worry. Without the plungers, they are harmless.

Frankly I'd be more worried about the 'whisk'  ;)

The solar arrays are shipped separately ??

Shipping the second European Service Module structure

For clarity: this is the "chassis" of the ESM for EM-2.
This is similar to LockMart currently constructing the pressure-vessel for the EM-2 Crew Module.

The solar arrays in the earlier post are for EM-1. The post about shipping the structure of the second ESM concerns the ESM for EM-2.

ESA contractors are working on multiple ESMs right now. The spare parts set that will ultimately become ESM-3 (for EM-3) is currently under construction as well.

EM-2 update:


Skeleton structure for Orion Moon Module arrives for assembly (in Bremen)

The structure for Europe’s second service module for NASA’s Orion spacecraft arrived at the Airbus clean room in Bremen, Germany, last week.
Technicians can now start working on installing over 12 km of cables, fuel, water and air tanks, computers, engines and everything else that is needed to support astronauts further from Earth than any human being has been before.

That's a very odd construction technique. Is that the most mass efficient way to build a service module? It looks like a temporary work rig that can be lowered or raised.

The struts you see prominently on the picture are ground tools installed only for transportation and handling.
They are needed because the ESM structure is so mass optimized that it cannot hold itself together without the other surrounding flight structures (cone adapter, crew module adapter).

More specifically the crew module adapter (CMA) and the outer shell panels. The Spacecraft Adapter (SA), also known as the cone adapter, is not needed for structural integrity of the ESM in 1G.
I refer to an earlier post of mine that shows the ESM STA without the prominent ground-handling struts.

Obviously my question was not clear enough. This Summer when the EM1 service module travels to the US does it travel with the solar panels attached or are they shipped separately.

Orion ESM – tank integration


Airbus Defence and Space
Published on May 6, 2018

In the Airbus facilities in Bremen, the integration of the propellant tank for the spaceship Orion, or to be precise, the integration in the European Service Module has been successfully finalized. The tanks will contain each about 2.000 liters of propellant. They found part of the propulsion subsystem together with 33 engines, pipelines, sensors and several electronic boxes.

They will be shipped separately. Same goes for a bunch of other stuff.

European skeleton for Orion

The structure for Europe’s second service module for NASA’s Orion spacecraft arrived at the Airbus clean room in Bremen, Germany, on 28 April.

Technicians started working on installing over 12 km of cables, fuel, water and air tanks, computers, engines and everything else that is needed to support astronauts further from Earth than any human being has been before.

The European Service Module is a crucial element of Orion, providing support to the crew module that will house up to four astronauts. The crew will travel over one million kilometres in total.

Wing span

The last time the solar wings of the European Service Module that will power the Orion spacecraft were featured, they were on a shaker table. They were exposed to launch vibrations and intense acoustic excitation at ESA’s Technical Centre in the Netherlands, to ensure they can survive the loud and shaky ride into space.

Having successfully passed these tests at ESA’s Technical Centre, the wings moved on to an Airbus’ clean room in Leiden, the Netherlands, for deployment testing. The solar wings are folded for launch but need to unfold once the Orion spacecraft is in space to start converting solar rays into electricity.

The fully deployed wings imaged here passed those tests as well, deploying in under two minutes, well within the 5 minute requirement. With the flick of a switch, thermal knives were energized, cutting through restrain cables to release the hold-downs in pairs.

ESA’s contribution to the Orion spacecraft provides power, propulsion, water, and air.

The first mission will take Orion around the Moon without astronauts and is scheduled for a 2019 launch. The solar panels will be folded inside the rocket fairing. Once released from NASA’s Space Launch System rocket they will unfold and rotate towards the Sun to start delivering power.

The solar wings are headed next to Bremen, Germany, where the wings will be integrated with the European service module. From there the service module is set to ship to the USA this summer for further tests and integration with the crew module adaptor.

Service module-1 main engine installation
 

An engine of the US Space Shuttle Orbital Manoeuvre System (OMS-E) was married with ESA’s European Service Module in Bremen, Germany.
 
This engine will provide the main thrust during Orion’s journey to the moon. It is one of 33 engines that were installed already.
 
Besides the OMS-E there are 8 auxiliary thrusters and 24 attitude control thrusters. The engine flew on 19 US Space Shuttle missions and is now ready for its last mission.
 
With this assembly all engines are now integrated into the Orion-ESM. The photo shows teams from Airbus, ArianeGroup and NASA during the integration of the engine.
