The CRS-6 launch will be broadcast live at www.spacex.com/webcast beginning at 4:15pm ET. Liftoff is targeted for 4:33pm ET.
Just Read the Instructions now on location in the Atlantic in advance of today’s launch, targeted for 4:33pm ET. Since the last landing attempt, the drone ship has been upgraded to tolerate more powerful ocean swells, however weather at the landing site is looking significantly better this time.
After Dragon and Falcon 9’s second stage are on their way to orbit, the first stage will execute a controlled reentry through Earth’s atmosphere, targeting touchdown on the autonomous spaceport drone ship approximately nine minutes after launch.

Project Orion The USAF Plan 1962
Dr. Brent Ziarnick, Major, USAFR, gives an excellent talk on Orion and the role it might have played as part of the US strategic nuclear forces.
The engineering and physics side of nuclear pulse propulsion has been covered in great detail through declassified documents such as the General Atomics report on Orion, which can be found here: GA-5009 vol III "Nuclear Pulse Space Vehicle Study Conceptual Vehicle Design" and George Dyson's book,* which is an essential study guide to Orion, detail on the USAF side of Project Orion is still emerging. This video provides an in depth look at the scope of those plans.

Update: 4/15/2015 New longer video shows just how close to a complete success the landing was. The vehicle definitely touched down on the barge, although it is also evident there was excessive lateral motion, and one lone thruster at the top firing in effort to prevent the topple.
