CAPE CANAVERAL, Fla. – The Ground Systems Development and Operations, or GSDO, Program completed its preliminary design review which allows development of the ground systems to proceed to detailed design. Representatives from NASA, its contractor partners and experts from across the aerospace industry met in the Mission Briefing Room inside the Operations and Checkout Building at NASA’s Kennedy Space Center in Florida to conclude the initial design and technology development phase. Completion of this review has validated that the baseline architecture is sound and aligns with the agency's exploration objectives. NASA is developing the Space Launch System and Orion spacecraft to provide an entirely new capability for human exploration beyond low-Earth orbit, with the flexibility to launch spacecraft for crew and cargo missions, including to an asteroid and Mars. Orion’s first unpiloted test flight is scheduled to launch later this year atop a Delta IV rocket. A second uncrewed flight test is scheduled for fiscal year 2018 on the Space Launch System rocket.

Kennedy Space Center Associate Director Kelvin Manning, right, speaks with a guest during a ceremony marking NASA's Spacecraft/Payload Integration and Evolution (SPIE) organization formally turning over processing of the Space Launch System (SLS) rocket's Interim Cryogenic Propulsion Stage (ICPS) to the center's Ground Systems Development and Operations (GSDO) Directorate. The ICPS is the first integrated piece of flight hardware to arrive in preparation for the uncrewed Exploration Mission-1. With the Orion attached, the ICPS sits atop the SLS rocket and will provide the spacecraft with the additional thrust needed to travel tens of thousands of miles beyond the Moon.

The concrete surface beneath the panels and the catacomb roof below will be inspected for water damage and repaired. There are 176 panels, each weighing about 30,000 pounds that will be removed. Launch Pad 39B is being refurbished to support NASA’s Space Launch System and other launch vehicles. The Ground Systems Development and Operations, or GSDO, Program office at Kennedy is leading the center’s transformation to safely handle a variety of rockets and spacecraft.

CAPE CANAVERAL, Fla. -- On the crawlerway leading to Launch Pad 39B at NASA’s Kennedy Space Center in Florida, workers from Canaveral Construction in Mims, Fla., continue to remove sections of the Alabama river rock in order to re-grade the lime rock below. The crawlerway is being upgraded to improve the foundation and prepare it to support the weight of NASA’s Space Launch System, or SLS, and mobile launcher on the crawler-transporter during rollout. Workers are removing the original Alabama river rock and restoring the layer of lime rock below to its original depth. Then new river rock will be added on top.

NASA engineers and test directors gather in Firing Room 3 in the Launch Control Center at NASA's Kennedy Space Center in Florida, to watch a demonstration of the automated command and control software for the agency's Space Launch System (SLS) and Orion spacecraft. The software is called the Ground Launch Sequencer. It will be responsible for nearly all of the launch commit criteria during the final phases of launch countdowns. The Ground and Flight Application Software Team (GFAST) demonstrated the software. It was developed by the Command, Control and Communications team in the Ground Systems Development and Operations (GSDO) Program. GSDO is helping to prepare the center for the first test flight of Orion atop the SLS on Exploration Mission 1.

CAPE CANAVERAL, Fla. – Tom Hoffmann, left, and Danny Zeno, both Ground Systems Development and Operations, or GSDO, integration engineers, sit inside one of four new emergency egress vehicles, called Mine-Resistant Ambush-Protected, or MRAP, vehicles at the Maintenance and Operations Facility at NASA’s Kennedy Space Center in Florida. The MRAPs arrived from the U.S. Army Red River Depot in Texarkana, Texas in December 2013. The vehicles were processed in and then transported to the Rotation, Processing and Surge Facility near the Vehicle Assembly Building for temporary storage. The GSDO Program at Kennedy led the efforts to an emergency egress vehicle that future astronauts could quickly use to leave the Launch Complex 39 area in case of an emergency. During crewed launches of NASA’s Space Launch System and Orion spacecraft, the MRAP will be stationed by the slidewire termination area at the pad. In case of an emergency, the crew will ride a slidewire to the ground and immediately board the MRAP for safe egress from the pad. The new vehicles replace the M-113 vehicles that were used during the Space Shuttle Program. Photo credit: NASA_Kim Shiflett

CAPE CANAVERAL, Fla. -- At NASA’s Kennedy Space Center in Florida, construction workers lower the large space shuttle-era Level E north work platform from high bay 3 inside the Vehicle Assembly Building, or VAB. The platform will be moved to the VAB north parking area for temporary storage. The work is part of a center-wide refurbishment initiative under the Ground Systems Development and Operations, or GSDO, Program. High bay 3 is being refurbished to accommodate NASA’s Space Launch System and a variety of other spacecraft. For more information, visit http://www.nasa.gov/exploration/systems/ground/index.html.
