Two years until the first SLS launches, I wonder what the hold up is?  Hope it is nothing major.

NASA aim for 2019 launch, but is not sure even about that !

Some of delay in short form

The NASA plant in New Orleans was hit by storm and was Damage, during repairs on building, work on SLS core was interrupted.
They redo welding on the core stage after inspection revealed low weld strengths.
If the Core can be deliver to KSC for testing in September 2017 is questionable

Orion capsule has delays because modification to systems and Heat shield after December 2014 test flight.
Airbus again has delays in Orion Service Module (former ATV) do underestimating the time and effort necessary to adapt the design.
Airbus will deliver Orion Service Module only in August 2017 to Lockheed facility
what make Orion ready for KSC transport not before August 2018 and delaying launch readiness testing to be ready in November 2018.
Next to that has Lockheed issue with some hardware and the Software on Orion spacecraft.

Missing needed Spacesuits for Orion Spacecraft.
after spending 200 million dollar on Space suits R&D NASA has no space suit ready for Orion spacecraft.
all they got are 18 old Shuttle spacesuits were 11 are operational and they usable for Orion spacecraft
the JSC space suits will be not ready before 2020 or 2024.

One moment why i mention spacesuits for EM-1 flight ?
now at NASA some in Administration proposed to make 2019 EM-1 a Manned Flight !

Thanks for the links Michel Van,  I am actually surprised that NASA are even considering making EM-1 a manned flight, a lot of things could go wrong on a first flight.

They're doing that because they were told to do that. But they'll produce a report that says "It will cost X, it will take Y more years, and it will increase the risk by Z." And X, Y and Z could all be really large numbers.

NASA Study Warns Against Putting Crew On Huge Rocketís First Flight

A review ordered by the Trump administration finds costs and scheduling problems.

12 May 2017

A NASA working group has concluded after a two-month review that sending astronauts on the first flight of its massive new rocket wouldnít be feasible due to the immense costs of safely accommodating a crew on the planned 2019 mission, the first step in Americaís return to human space exploration.

Decision on EM-1 launch date still pending

Quote
HUNTSVILLE, Ala. ó NASA is still up to a month away from setting a new target launch date for the first flight of the Space Launch System, but agency officials said they still expected it to take place in 2019.

NASA has not set a new date for Exploration Mission (EM) 1, which will launch an uncrewed Orion spacecraft on a test flight into lunar orbit and back, since announcing in May that it would delay the flight to 2019 after deciding not to put a crew on the mission.

At this rate both SpaceX and Blue Origin are going to leave them in the dust.  :P

Not really. Being as it seems an increasingly remote possibility that FH will even fly for the first time this year, far more likely 2018, something like four years late. BO arenít even slated to start flying until 2020 at the earliest.

Maybe the takeaway message is that large rockets are difficult to build, and they take longer than people expect.

Unless it's a Saturn V anyway.

During the peak of Apollo, 5% of the federal budget was going to NASA. That's a lot of money. The edict was "waste anything but time."

Imagine what Spacex/Blue Origin could do (or have accomplished by now) with an SLS size budget.  SLS is a rehashed Constellation-Ares V and uses modified hardware from the shuttle.  That is the foundation for $10 Billion in expenditures (just the rocket) to date.

Back in the 60's, NASA was very different from today (not just in budget or size but mainly in culture).  The Gemini project was conducted for less than $1.5 Billion (yes those are 60's dollars but it is also total program cost including space capsule). For that, NASA flew 10 manned missions within a program span of just 5 years.

And that leads back to the other issue of what to do with SLS if it finally reaches hardware readiness.  Any project which thinks of using it will be faced with the financial penalty of funding an SLS launch. I would hope that any future space project be required to examine COTS launch alternatives in their planning.  The results will be interesting.

Around $200 billion now.

That's today $10 billion
Include R&D on Gemini Spacecraft, new Space suits, etc. $5.875 Billion
modification of Titan II to Manned Launcher, Docking adapter on Agena $3.019 Billion
with 12 Titan II and 7 Atlas Agena Launches  (and one reuse of Gemini 2 on Titan IIIC under MOL) 
Mission Support & rest $561.4 Million.

Comparison:
NASA Orion R&D around $20.4 billion from 2006 to 2023 [the first manned flight on SLS]
SpaceX Dragon 1 R&D was $819 Million (source Wiki)
Dragon 2 no data.
Boeing on CT-100 Starliner no data.
Blue Origin no info about manned orbital craft

I love Strange Technology
