That's right folks. That massive turn basin that received Shuttle ETs and Saturn Vs isn't big enough for SLS on enlarged Pegasus.

Turn Basin Prepped for Space Launch System Core Stage Arrival


Modifications are underway at the Launch Complex 39 turn basin wharf at NASA's Kennedy Space Center in Florida to prepare for the arrival of the agency's massive Space Launch System (SLS) core stage aboard the Pegasus barge. Precast concrete poles are being driven to a depth of about 70 feet into the bedrock below the water around the turn basin. The upgrades are necessary to accommodate the increased weight of the core stage along with ground support and transportation equipment aboard the modified barge Pegasus.

When the core stage for NASA's massive Space Launch System (SLS) rocket departs the Michoud Assembly Facility in New Orleans, it will be shipped by barge to the Launch Complex 39 turn basin wharf at NASA's Kennedy Space Center in Florida to be integrated with other hardware in preparation for its first launch, known as Exploration Mission-1. Modifications are underway to upgrade the wharf and prepare for the arrival of the core stage.

Located just across the street from the iconic Vehicle Assembly Building (VAB), the dock area that was used for arrival and offloading of space shuttle external tanks is getting a makeover to accommodate the core stage when it arrives aboard NASA's modified barge Pegasus. The 212-foot-long core stage, which is more than 50 feet longer than the space shuttle tank, serves as the structural backbone of the rocket and includes the SLS propellant tanks and four RS-25 engines. When Pegasus arrives at Kennedy's turn basin, it will be carrying the core stage and all its ground support and transportation equipment -- cargo that is more than 600,000 pounds heavier than Pegasus transported for the space shuttle.

"The turn basin is undergoing significant structural modifications and electrical upgrades to be ready for the core stage and Pegasus barge," said Jimmy Rogers, a project manager with Kennedy's Ground Systems Development and Operations (GSDO) Program. "Analysis was performed on how Pegasus was going to be moored at the wharf to offset wind load scenarios. The barge's length was increased to 310-feet-long to meet barge-to-dock interface requirements for the core stage."

The electrical system also is undergoing upgrades to meet new power requirements necessary to support Pegasus barge offloading operations. The new electrical system includes power receptacles for the SLS mobile transporter, which will carry the core stage to the VAB for processing and stacking.

Demolition and new construction began in December 2016 and is scheduled to be completed in August 2017. Southeast Cherokee Construction Inc., a woman-owned small business, is managing construction associated with the project for GSDO.

The work includes driving multiple precast concrete piles to a depth of about 70 feet around the wharf. A crawler crane lifts and sets each pile in place. When they are at a specified location, a pile-driving rig "hammers" the piles through soil and bedrock below the water. Concrete also is being added to strengthen the wharf.

"Ultimately, the wharf soon will be ready to receive the core stage, as well as other flight hardware components scheduled for delivery at Kennedy," Rogers said.

NASA is preparing for the first integrated mission of the Orion spacecraft with the SLS rocket in 2019. During the uncrewed flight test, Orion will travel tens of thousands of miles beyond the moon and return home with a splashdown in the Pacific Ocean.

Во вчерашней статье на NSF есть прекрасное. Они сваривали водородные баки (два изделия) без прохождения всех проверок оборудования. В результате нашли брак в сварном шве, изделия придется переделывать. А нижний купол кислородного бака тупо уронили. Тоже на переделку.

Это уже стало доброй традицией. После сборки сварочной машины обнаружили что забыли укрепить фундамент и ее перекосило. Пришлось разбирать, укреплять и собирать заново.

Kennedy Engineers to Support Liftoff of World's Most Powerful Rocket
Posted on July 11, 2017 at 9:57 am by Anna Heiney.

Liftoff of NASA's Space Launch System (SLS) rocket and Orion spacecraft from Launch Complex 39B at the agency's Kennedy Space Center in Florida will require a symphony of tightly coordinated commands for processing and launch. Kennedy engineers recently achieved authorization to operate the Kennedy Ground Control Subsystem, which is a network of controls, during hazardous operations at the Multi-Payload Processing Facility. The processing facility is used to prepare Orion for its test flight atop the SLS.

To gain authorization to operate, Kennedy updated access to the subsystem network and equipment, ensuring the network is secure from all malicious threats, whether internal or external. Kennedy now is prepared to support hazardous operations and ensures that the network meets agency standards for network and physical protection.

According to Reggie Martin, a NASA electrical engineer in the Engineering Development Lab at the center, an authorization is good for only one year.

"Each subsequent authorization is a review to ensure we continue to operate at the level first certified to operate," Martin said. "It also includes a review of any new equipment or operations to ensure they are properly incorporated as we get closer to the launch of NASA's Space Launch System on Exploration Mission-1."

The subsystem of the Spaceport Command and Control System is the main integration network system between ground support equipment at Kennedy and the Launch Control Center. The network interfaces with ground support equipment, such as sensors, valves and heaters, with systems in the Vehicle Assembly Building, mobile launcher, Launch Pad 39B, Launch Abort System Facility and the payload processing facility to facilitate monitoring and control of subsystem processes.

"We're responsible for ensuring all ground operations are transmitted to ground support equipment to ensure timely launch processing and vehicle launch from the launch pad," said Martin.

Martin led a team of NASA and contractor engineers in the integrated design, fabrication, installation, verification and validation of the mission's operational information and security requirements in support of hazardous operations.

The Kennedy subsystem is monitored by NASA and contractor engineers from consoles located in the Launch Control Center's Firing Room 1.

SLS Test Hardware Loaded into NASA's Super Guppy Aircraft


 
NASA engineers load a structural test version of the Orion Stage Adapter for NASA's Space Launch System onto NASA's Super Guppy Aircraft at the Redstone Arsenal Airfield in Huntsville, Alabama, for delivery to Lockheed Martin in Denver. The OSA connects NASA's Orion spacecraft to the Interim Cryogenic Propulsion System, which will give the spacecraft its big, in-space boost to fly around the moon in its first integrated flight with SLS. Built at NASA's Marshall Space Flight Center in Huntsville, the OSA was used in integrated structural testing for the top of the SLS rocket and will be used in similar testing with Orion at Lockheed. The Guppy has a cargo compartment that is 25 feet tall, 25 feet wide and 111 feet long and can carry up to 24 tons. The aircraft has a unique hinged nose that can open 110 degrees, allowing large pieces of cargo to be loaded and unloaded from the front.

Core Stage Forward Skirt Umbilical Installed on Mobile Launcher
Posted on July 13, 2017 at 2:24 pm by Anna Heiney.

The Core Stage Forward Skirt Umbilical (CSFSU) recently was installed on the tower of the mobile launcher at NASA's Kennedy Space Center in Florida, to prepare for the first launch of the agency's Space Launch System (SLS) rocket with the Orion spacecraft atop.

Спойлер

Just north of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, technicians install the core stage forward skirt umbilical on the mobile launcher.
 


The mobile launcher tower will be equipped with a number of lines, called umbilicals, which will connect to the SLS and Orion spacecraft and provide commodities during processing and preparation for launch of Exploration Mission-1.

Cranes and rigging were used to lift the CSFSU and install it at about the 220-foot-level on the tower. The CSFSU will swing into position to provide connections to the core stage forward skirt of the SLS rocket, and then swing away before launch. Its main purpose is to provide conditioned air and gaseous nitrogen to the SLS core stage forward skirt cavity.

The Ground Systems Development and Operations Program is overseeing installation of the umbilicals on the tower.
