More work has been done prepping for installing the rails the VAB platforms will translate vertically on.
Since this website (http://mediaarchive.ksc.nasa.gov/) is no longer updated and to voice my frustration with the individuals who are no longer progressing on the Gallery's transition and my annoyance with Flickr, pics can be found here: https://www.flickr.com/photos/nasakennedy/sets/72157649473620280/

If anyone knows the link to the new alternate web portal that is replacing the Kennedy Media Gallery please enlighten me and others by replying to my post with the link. If I get the new link I will resume posting images here.
Well http://mediaarchive.ksc.nasa.gov/ is now officially dead:

DCSS vs EUS status:

http://www.nasaspaceflight.com/2015/06/nasa-resolve-sls-upper-stage-dilemma/

A serious matter, but it is good they're giving more thought that favors putting Block 1B quickly into operation and mitigate unnecessary use of Block 1 stuff.

Aft Segment Cast for Second SLS Booster Qualification Test
July 24, 2015 - Jennifer Harbaugh

The aft segment for a full-scale version of a five-segment solid rocket booster for NASA's Space Launch System has been cast at Orbital ATK's facility in Promontory, Utah. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars. The aft segment will eventually be integrated with the other four booster segments for a second booster qualification test, scheduled for 2016. The first SLS qualification test for the booster was successfully completed March 11 at Orbital ATK. The second test will support qualification by specifically assessing performance at the cooler end of the motor’s accepted propellant temperature range. After qualification is complete, the boosters will then be ready to proceed toward the first flight of SLS. Orbital ATK is the prime contractor for the boosters. Learn more about the boosters here.

NASA TV to Air Test of Space Launch System Engine

NASA Television will broadcast live coverage Thursday, Aug. 13 of the penultimate hot fire test of an RS-25 engine. This is one of four engines that will power the core stage of NASA’s new Space Launch System (SLS), and carry the agency’s Orion crew capsule as part of the journey to Mars and other deep space destinations.

From 11 a.m. to 12:30 p.m. EDT, NASA TV will broadcast a series of conversations at Stennis among media, social media followers, engineers and managers discussing the SLS rocket, Orion, ground systems, and the RS-25 engine. Viewers can ask questions via social media using the hashtag #askNASA.

Coverage of the 5 p.m. engine test will begin at 4:30 p.m. The test will last 535 seconds, the amount of time the engines will fire during an actual launch. Both programs can be viewed on NASA TV-1, the public channel for the space agency, and NASA TV-2, the education channel.

The test will take place on the historic A-1 test stand at NASA’s Stennis Space Center in Mississippi and is part of a series designed to put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a launch.

The tests also support the development of a new controller, or “brain,” for the engine, which monitors engine status and communicates between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine's health and status.

Status from ASAP:

http://www.nasaspaceflight.com/2015/08/asap-status-sls-orion-red-risks/

Went around the houses a bit with this one (more than I intended).

So: A throwback to CxP (for a few reasons - 1) Because it's interesting where they would be now had it actually worked. 2) There was a reference to a concern that was a CxP concern later in the article. 3) SLS is doing better than CxP, reference).

Will be going into the heat shield and parachutes some more in future articles, such as during the upcoming drop test, so I didn't skip over them, referenced them and will expand later. Would have also been massively wordy otherwise.

Dipped into some program stuff with the CSI references (because we haven't before and that's something to cover).

Had a little poke at them still using a painted SLS core....as it tied into CxP references with the Ares V ;)

Yeah, anyway - hopefully it's an interesting read.

(Responses to the discussion thread - split them into there :) )

The Heat Goes On as Engineers Start Analysis on SLS Base Heating Test Data

Published on Sep 2, 2015
Mini models of the Space Launch System (SLS) core stage engines are ignited in a big way for a short-duration hot-fire test at 101 percent power level. As the main objectives of the Pathfinder Test Program, models of the SLS core stage RS-25 engines and solid rocket boosters -- scaled down to just 2 percent of the actual size of the flight hardware -- have been designed, built and hot-fire tested at sea-level conditions by Marshall Space Flight Center engineers, in close collaboration with CUBRC Inc. in Buffalo, N.Y. The replicas will provide data on the convective heating environments that the base of the vehicle will experience upon ascent. The models were developed for base heating testing, which wrapped up in August. When completed, SLS, NASA's new rocket, will be one of the biggest, most powerful rockets ever built.

Major Welding Begins on Crucial Connection for SLS

Published on Sep 9, 2015
Major welding has begun at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on a structural test article of the launch vehicle stage adapter (LVSA), which connects the core stage to the upper stage of NASA’s new rocket, the Space Launch System.

The upper stage, known as the Interim Cryogenic Propulsion Stage, gives the Orion spacecraft the big, in-space push needed to fly beyond the moon before the spacecraft returns to Earth for the first flight test of SLS. The work is in close collaboration with prime contractor Teledyne Brown of Huntsville.

In addition, NASA engineers have already completed structural test articles of the Orion stage adapter, core stage simulator and Orion spacecraft simulator. A test article for the interim cryogenic propulsion stage is currently in production at United Launch Alliance in Decatur, Alabama.

When the test versions of all the parts are completed, engineers will stack them and move the 56-foot tall structure to a Marshall test stand for testing to verify the integrity of the hardware and ensure it can withstand the loads it may experience during flight.

Booster Hardware Readied for First Flight of NASA’s Space Launch System
Oct. 1, 2015 Jennifer Harbaugh

Technicians at Orbital ATK in Promontory, Utah, offload an aft dome and aft stiffener that will be used on one of the two, five-segment solid rocket boosters for the first flight of NASA’s new rocket, the Space Launch System (SLS). The boosters operate in parallel with the main engines for the first two minutes of flight to provide the thrust needed for the launch vehicle to escape the gravitational pull of Earth. The aft dome is a component of the aft segment of the booster, which is located at the bottom of the booster during flight. The flight hardware is being processed at Orbital ATK’s facility. Later, the motor segments will be transported by rail to NASA's Kennedy Space Center in Florida, where they will join the forward and aft skirt assemblies. Once the boosters are assembled and checked out, they will be mated with the SLS core stage in the Vehicle Assembly Building at Kennedy.

RELEASE 15-203
NASA Names John Honeycutt Space Launch System Program Manager

NASA has named John Honeycutt manager for the agency’s Space Launch System (SLS) Program. Now under development, SLS will be the most powerful rocket ever built -- able to carry astronauts in NASA's Orion spacecraft on deep space missions, including to an asteroid and ultimately to Mars.

As SLS program manager, Honeycutt leads a nationwide workforce of more than 4,200 civil servants and contractors with an annual budget of $1.7 billion, and is responsible for all facets of the program, including planning, procurement, development, testing, evaluation, production and operation of the integrated SLS.

Honeycutt, who had been deputy manager of SLS since November 2013, has helped lead the program through a series of milestones, including engine tests and in-depth element and system critical design reviews.

"John is an accomplished manager, and I'm pleased he is assuming this new leadership role in the development of SLS as we continue taking great steps forward in the continuous human exploration of space and on our journey to Mars," said William Gerstenmaier, NASA’s associate administrator for the Human Exploration and Operations Mission Directorate.

Honeycutt succeeds Todd May, who in August was named deputy director of NASA’s Marshall Space Flight Center in Huntsville, Alabama, where the SLS program is managed.

"NASA has benefited from John's management and leadership skills in a number of programs at Marshall over the years, and I'm pleased he'll be responsible for the continuing success of SLS, the next great vehicle to launch our human exploration space missions," said Marshall Center Director Patrick Scheuermann.

Honeycutt began his NASA career at Marshall in 1999 after working for nine years as a contractor in support of the Space Shuttle Program, the International Space Station and other NASA programs. At Marshall, he has served as deputy manager and manager of the Space Shuttle External Tank Project, deputy manager of the SLS Program Stages Office and SLS deputy chief engineer.

He earned a bachelor’s degree in mechanical engineering from the University of Alabama in Huntsville in 1990. He has received numerous awards, including a NASA Exceptional Achievement Medal, Management Space Flight Awareness Award, the Silver Snoopy Award and a Center Director’s Commendation.

More Than 50 Pieces of Hardware Completed for SLS Core Stage Tanks
Oct. 19, 2015 Jennifer Harbaugh

Technicians at NASA’s Michoud Assembly Facility in New Orleans have completed more than 50 pieces of flight and qualification hardware for the liquid oxygen and liquid hydrogen tanks for the agency’s new rocket, the Space Launch System (SLS), and are ready to move forward with welding. SLS will be the most powerful launch vehicle ever built for deep space missions, including to an asteroid placed in lunar orbit and ultimately to Mars. The core stage, towering more than 200 feet, will store cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle’s four RS-25 engines. The qualification hardware will be used to make test versions of the tanks. When completed, the test version tanks will be shipped aboard NASA’s Pegasus barge to the Marshall Space Flight Center in Huntsville, Alabama, for structural loads testing on new stands currently being built. The flight hardware will be used on the maiden flight of SLS, called Exploration Mission-1. Watch a video on the progress at Michoud.
