CAPE CANAVERAL, FL - The European-built service module for NASA’s Orion crew spacecraft has completed acoustic testing inside the Operations and Checkout Building at NASA’s Kennedy Space Center in Florida as critical work continues apace to prepare the vehicle for launch on the Artemis 1 mission in late 2020.
NASA hopes to return humans to the surface of the Moon at the lunar south pole by 2024 on the Artemis 3 mission under new plans approved by the Trump Administration and announced by VP Mike Pence and NASA Administrator Jim Bridenstine.
The acoustic testing on the combined Orion European Service Module (ESM) and Crew Adapter Module was completed on May 25, 2019 after completing the installation of all four solar array wings on May 10.
“The tests were the latest step in preparing for the agency’s first uncrewed flight test of Orion on the Space Launch System (SLS) rocket,” NASA officials said.
The acoustic tests – called the Direct-Field-Acoustic Testing (D-FAT) – are run to simulate the extreme noises of a rocket launch and ensure the spacecraft will survive a real launch on the SLS from KSC Launch Complex 39B.
For the D-FAT test the service and adapter modules are “surrounded by large speakers set at full blast to ensure the spacecraft survives the vibrations and loud noise generated from the Space Launch Systems rocket liftoff.”
Sound bombardment engineers are now running functional tests to determine whether the electronics are still working correctly.
“Technicians will analyze the data collected during the tests to check for flaws uncovered by the acoustic environment. During the testing, engineers secured the service module inside the test cell and then attached microphones, strain gauges and accelerometers to it. They conducted a series of five tests, with acoustic levels ranging from 128 to 140 decibels – as loud as a jet engine during takeoff."
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 Moon and 40,000 miles (64,000 km) beyond atop SLS-1 during Artemis-1 from KSC pad 39B.
The first European Service Module (ESM-1) built to power NASA’s Orion crew spacecraft for human voyages to deep space was unveiled at a welcoming ceremony held at NASA’s Kennedy Space Center (KSC) in Florida in November 2018 – see our photos – after being transported from Bremen, Germany where it was manufactured for ESA.
The next step this month is for the team to carry out the propulsion functional test whereby “commands are sent to test the system and ensure everything interacts as needed” – but not actually fire the engines.
The propulsion test firings will be done later at NASA’s test facility in White Sands, New Mexico.
All four 7-meter long solar wings were removed following the D-Fat test conclusion.
The next big milestone will be mating of the ESM with the Orion Artemis-1 Crew module in July into a unified 7.3 meter tall structure the size of a two-story house.
Thereafter
the Orion Artemis -1 CM/ESM vehicle will be carefully loaded horizontally into
the belly of the 'Super Guppy' - NASA's
one of a kind, gorgeous hybrid aircraft.
The Super Guppy will transport it from the Kennedy Space Center to NASA’s Plum Brook facility for critical thermal vacuum, acoustic, electromagnetic testing prior to the uncrewed lunar test flight. Launch on SLS-1 is scheduled for late 2020.

The Super Guppy will transport it from the Kennedy Space Center to NASA’s Plum Brook facility for critical thermal vacuum, acoustic, electromagnetic testing prior to the uncrewed lunar test flight. Launch on SLS-1 is scheduled for late 2020.
The next test launch
in the Orion program is slated for July 2 involving the Ascent Abort-2 test from pad 46 on Cape Canaveral Air Force
Station. Watch for our upcoming coverage.
During the flight an Orion test
article will launch on a Minotaur 4 booster to more than six miles in altitude,
where Orion’s launch abort system (LAS) will pull the capsule and its crew away
to safety in a split second in a simulated rocket emergency during ascent on
the Space Launch System
rocket.
Artemis 1 will be the first mission launching Orion on
the SLS rocket from Kennedy’s Launch Pad 39B. The mission will take Orion
thousands of miles past the Moon on an approximately three-week test flight.
Orion will return to Earth and splashdown in the Pacific Ocean off the coast of
California, where it will be retrieved and returned to Kennedy.
