RocketSTEM –28 November 2018
space was unveiled at a welcoming ceremony held at NASA’s Kennedy Space Center (KSC)
in Florida – where it is now being processed for the 1st integrated
test flight launch to the Moon atop the mammoth Space Launch System (SLS)
megarocket on the Exploration Mission-1 (EM-1) in 2020.
NASA
hosted the welcoming event for this first European Service Module – dubbed
ESM-1 – inside the cavernous Neil Armstrong
Operations and Checkout building at KSC on Nov. 16 – and attended by a big crowd of dignitaries from NASA, the
European Space Agency (ESA) who funded its development, the main European and
US industrial contractors and the news media including Space UpClose.
“We will not go back to the moon … We will go forward to the
moon,” said
ESA Director General Jan Wörner at the “Powering EM-1” KSC media event.
“We will go in a totally different way to the moon. Not in competitive
manner but in a very cooperative manner … to motivate the future.”
we celebrate the delivery of the European Service Module, said NASA
Administrator Jim Bridenstine.
USA is very grateful for our partners at the European Space Agency and all its
member nations.”
“This
is a momentous occasion where we will have the opportunity to fly into deep
space. And the European Service Module is a huge element of this architecture.”

The cylindrically-shaped
European Service Module ESM-1 is the critical ‘powerhouse’ element that will
supply NASA’s human-rated Orion spacecraft with electricity, propulsion,
thermal control, air and water and propel it on its first voyage to the the Moon and 40,000 miles (64,000 km) beyond atop SLS-1 during
EM-1 from KSC pad 39B.

“This
powerhouse element is what we need to go farther than ever before,” said Mark Kirasich, NASA’s
Orion program manager.
“In
space the two halves must operate flawlessly.”
“It’s a great day @NASAKennedy with
our @esaspaceflight @AirbusSpace @LockheedMartin
partners with the delivery of the #OrionESM !” tweeted Kirasich.
ESM-1 was funded and developed by the European Space Agency (ESA) and
manufactured by prime contractor Airbus in Bremen, Germany and Turin, Italy with components supplied by
companies all over Europe.
After
years of separate development the two main components are finally together in
the same place for mating and more!
“Finally together! @NASA_Orion‘s
service and crew modules are both at @NASAKennedy,
and this is just the beginning – the first leg of an exciting #JourneyToTheMoon,”
tweeted ESA.
The
implications here are huge because this marks the first
time that NASA “will use a European-built system as a critical element to power
an American spacecraft, extending the international cooperation of the
International Space Station into deep space.”
Eventually
future ESMs will power Orion astronauts to the Moon and beyond on mission to
deep space starting with Exploration Mission-2 (EM-2) as soon as 2022 after
life support and other systems are incorporated.
ESM
serves the same role as the Apollo Service Module (SM) during NASA’s Apollo Moon
landing missions in the 1960s and 1970s.
Orion and SLS
are under development by NASA to lead humanity back to a permanent presence
at the Moon
together with partners including Europe and potentially Russia, Canada and Japan.
NASA’s
Gateway human tended lunar orbiting outpost is key to NASA human ‘Return to the
Moon’ architecture says NASA Administrator Jim Bridenstine.
“We are in a good place to be a partner for
the lunar Gateway,” says Jan Wörner. r

The
next step is to test, connect and integrate the two hardware components together
with NASA’s Orion Crew Module stacked atop ESA’s Orion Service Module – just like the Apollo Command and Service modules.
That effort
begins now inside the Neil Armstrong Operations & Checkout (O & C) high bay at KSC where the crew module is being manufactured by prime contractor
Lockheed Martin.
The cylindrically
shaped ESM arrived at the entrance to the O & C later the same day in flew
here aboard the Antonov.
“Come on in; we’ve been waiting for you! The @esa @AirbusSpace European
Service Module is at the door of the @NASAKennedy Neil Armstrong Operations and Checkout Building!”
tweeted Mark Kirasich, NASA’s Orion program manager.
“Engineers will complete functional checkouts to
ensure all elements are working properly before it is connected to the Orion
crew module. Teams will weld together fluid lines to route gases and fuel and
make electrical wiring connections,” NASA reported.
The
team is already hard at work and had already connected the Orion Crew Module Adapter
to the top of ESM-1 by the day of the event using 192 bolts that “are needed to keep the structure together and withstand the
immense forces of launch and spaceflight.”
by technicians to attach the Crew Adapter to ESM-1 with the 192 bolts was arduous
and excruciating at the complex interfaces between them, explained Philippe
Berthe, ESA’s ESM program manager for Orion.

enables them to start working on connections for
power, data and welding the pipes for the fluids such as water and fuel between
the two main modules.
EM-1 crew module will be connected next to the Adapter and ESM-1.
For the thousands of miles (km) journey across
the Atlantic Ocean the ESM “was packed in a custom-built container that keeps
the environment inside within acceptable limits for transportation,” said ESA.
contractor Airbus Defence & Space designed and manufactured the ESM at
facilities in Bremen, Germany and Turin, Italy with over 20,000 parts provided
by companies across ESA’s partner nations. The design builds on heritage from
ESA’s now retired Automated Transfer Vehicle (ATV) which
served as a cargo freighter for the ISS.

The service module is equipped with four
giant solar array wings that span 19 meters when deployed and provide
enough electricity to power two three-bedroom homes, as well as the orbital
maneuvering system.
Each solar wing measures 2 m wide by 7 m in
length. The four wings contain 15,000 solar cells to convert light into the electricity
that powers Orion.
Radiators and heat exchangers help maintain comfortable
temperatures, “while the module’s structure is the backbone of the entire
vehicle, like a car chassis,” according to ESA.
One of the key challenges was keeping the ESM
spacecraft mass within tight limits.
“If you want to go far, you must go light,” explained Philippe
Berthe.
“We have been on a 7-year diet to get
everything included. So we took some short cuts for EM-1 because of the schedule.
But we have plans for the future modules to be compliant.”
“We still need to lose some weight for EM-2 and
beyond.”
“EM-2 is mass constrained. EM-1 was not.”
