Engineers and technicians moved the Orion service module test article into the Reverberant Acoustic Test Facility at NASA Glenn Research Center’s Plum Brook Station in Sandusky, Ohio on April 8, 2016. Acoustic testing is scheduled to begin April 18. The blue structure sitting on top of the test article is a mass simulator that represents the Orion crew module...The test article will be blasted with at least 152 decibels and 20-10,000 hertz of sound pressure and vibration to simulate the intense sounds the Orion service module will be subjected to during launch and ascent into space atop the agency’s Space Launch System (SLS) rocket. This is part of a series of tests to verify the structural integrity of Orion’s service module for Exploration Mission-1, the spacecraft’s first flight atop SLS...Provided by ESA (European Space Agency) and built by Airbus Defence and Space, the service module will power, propel and cool the vehicle and also supply it with air and water.

In their Swamp Works laboratory at NASA's Kennedy Space Center, Dr. Carlos Calle and Jay Phillips are testing an electrostatic precipitator using dust that closely approximates the make-up of that on Mars. They upgraded their electrostatic precipitator to fully simulate Martian atmosphere by designing and constructing a dust aerosolization pre-chamber. The agency's Journey to Mars requires cutting-edge technologies to solve the problems explorers will face on the Red Planet. Scientists are developing some of the needed solutions by adapting a device to remove the ever-present dust from valuable elements in the Martian atmosphere. Those commodities include oxygen, water and methane.

Students visit the displays at the Logan Heights Library in San Diego, California, during the “52 Weeks of Science” celebration. The Ground Systems Development and Operations (GSDO) Program is participating in the special event with a Journey to Mars display before the start of Underway Recovery Test 5 using a test version of the Orion spacecraft in the Pacific Ocean off the coast of California. The test will allow NASA, Orion manufacturer Lockheed Martin and the U.S. Navy to demonstrate and evaluate the recovery processes, procedures, hardware and personnel necessary for recovery of the Orion crew module on its return from a deep space mission. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and NASA Journey to Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. Orion is scheduled to launch atop NASA’s Space Launch System rocket in 2018. For more information, visit http://www.nasa.gov/orion.

A test version of the Orion crew module floats outside the well deck of the USS San Diego on the fourth day of Underway Recovery Test 5 in the Pacific Ocean off the coast of California. NASA's Ground Systems Development and Operations Program and the U.S. Navy are practicing retrieving and securing the crew module in the well deck of the ship using tethers and a winch system to prepare for recovery of Orion on its return from deep space missions. The testing will allow the team to demonstrate and evaluate recovery processes, procedures, hardware and personnel in open waters. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and NASA's Journey to Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. Orion is scheduled to launch on NASA's Space Launch System in late 2018. For more information, visit http://www.nasa.gov/orion.

A sunrise is in view from the flight deck of the USS San Diego in the Pacific Ocean off the coast of California. NASA's Ground Systems Development and Operations Program and the U.S. Navy are conducting a series of tests, called Underway Recovery Test 5, using the ship's well deck and a test version of the Orion crew module to prepare for recovery of Orion on its return from deep space missions. The testing will allow the team to demonstrate and evaluate recovery processes, procedures, hardware and personnel in open waters.

A construction worker wearing a safety harness and tethered lines monitors the progress during the installation of the second half of the B-level work platforms, B north, for NASA’s Space Launch System (SLS) rocket, high up in the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The B platform will be installed on the north side of High Bay 3. The B platforms are the ninth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.

Progress continues on the new flame trench at Launch Pad 39B at NASA's Kennedy Space Center in Florida. Construction workers with J.P. Donovan of Rockledge, Florida, prepare new heat-resistant bricks for installation on the north side of the flame trench. The Pad B flame trench is being refurbished to support the launch of NASA’s Space Launch System rocket. The Ground Systems Development and Operations (GSDO) Program at Kennedy is helping transform the space center into a multi-user spaceport and prepare for Exploration Mission 1, deep space missions, and NASA's Journey to Mars.

Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, construction workers assist with the installation of the first half of the C-level work platforms, C south, for NASA’s Space Launch System (SLS) rocket. The large bolts that hold the platform in place on the south wall are being secured. The C platforms are the eighth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.

High up in the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida, a crane lowers the second half of the B-level work platforms, B north, for NASA's Space Launch System (SLS) rocket, for installation in High Bay 3. The B platform will be installed on the north side of high bay. In view below are several levels of previously installed platforms. The B platforms are the ninth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.
