Many folks would like to see us back on the Moon and developing its resources.

NASA Scrubs Orion Launch For Today, 4 December 2014

I failed to get up at 4 am here on the west coast to watch the launch.
It turned out the weather and some rocket anomalies scrubbed the launch which will be attempted tomorrow, 5 December 2014.
I have been watching the post launch debrief link that passed in their daily email.

NASA Scrubs Orion Launch For Today
December 04, 2014 8:19 AM ET

Update at 9:35 a.m. ET

NASA's Orion spacecraft, which could one day send astronauts to Mars, is stuck on terra firma for at least another day after the space agency's mission control was unable to satisfactorily resolve a number of issues before a 9:45 a.m. launch window closed.

The unmanned vehicle is awaiting its first test in Earth orbit. But after multiple delays for high winds and a stuck liquid-oxygen drain valve on one or more of the Delta IV Heavy rocket's booster engines, NASA didn't have time to get the rocket off the pad. It will try again Friday morning.

The vehicle perched atop the Delta rocket, known officially as Orion Multi-Purpose Crew Vehicle, or MPCV, is designed to carry up to four astronauts.

I have been watching NASA TV from a link that passed.
They have been replaying the Post Launch Debrief to the press.

Today's attempt to launch Orion EFT-1 has been scrubbed today after continuing issues with ground winds - and then with fill and drain valves on the Delta IV Heavy Launch vehicle. There were also issues with battery levels on the rocket's video system. The plan seems to be to try again tomorrow with a 7:05 am ET launch time.

Update: According to speakers at today's NASA press briefing, the ship that caused the launch delay was never in a position to present a safety hazard. While winds caused the first two scrubs, the ultimate scrub for the day had to do with sluggish response times for liquid Hydrogen valves on the Atlas IV Heavy. This is an issue that has been seen before on a prior launch. There are also some minor issues having to do with battery life for instrumentation inside of Orion and inside the Delta IV Heavy rocket that are being addressed. If a launch attempt is made tomorrow but is not successful, then ULA will need to skip over Saturday in order to replenish ground tanke supplies. Overall the tone of the briefing was that this all went by the books, the issues are understood and can be handled.

Friday Opportunity at 7:05 A.M. EST

The launch team has tentatively set a liftoff time of 7:05 a.m. EST, the opening of a 2-hour, 39 minute window just as today. We will begin our launch coverage at 6 a.m. tomorrow on NASA TV and on the Orion blog. Tune into the blog and for continuing updates throughout the day.

Thanks for looking up with me.

The Orion Multi-Purpose Crew Vehicle (MPCV) is a spacecraft intended to carry a crew of up to 4[2] astronauts to destinations beyond-low Earth orbit (LEO). Currently under development by NASA[8] for launch on the Space Launch System,[9] Orion will facilitate human exploration of the Moon, asteroids and Mars.

The MPCV was announced by NASA on May 24, 2011.[10] Its design is based on the Orion Crew Exploration Vehicle from the cancelled Constellation program.[11] The Orion command module is being built by Lockheed Martin. The Orion Service Module, provided by the European Space Agency,[12][13] is being built by Airbus Defence and Space.

The MPCV's debut uncrewed test flight, known as Exploration Flight Test 1 (EFT-1), is scheduled to be launched aboard a Delta IV Heavy rocket on December 4, 2014.[3][4][14] The first crewed mission is expected to take place after 2020.[15]...
ORION Quick Facts

Orion is America’s next generation spacecraft that will take astronauts
to exciting destinations never explored by humans. It will serve as the
exploration vehicle that will carry the crew to distant planetary bodies,
provide emergency abort capability, sustain the crew during space
travel, and provide safe reentry from deep space.
