[QUOTE=xilman;398886]That is a really nice presentation![/QUOTE]
In what appears to be a miscue in the article, they refer to the engine as a Merlin derived engine, while I understand the [URL="http://en.wikipedia.org/wiki/Raptor_(rocket_engine)"]Raptor[/URL] to be a different engine family. The Raptor is much more that a scaled up Merlin.

SpaceX Falcon Rocket vs. Robot Boat: Round Two!

[URL="http://rt.com/usa/249081-nasa-human-lab-rats/"]NASA offering $18,000 for human lab rats to stay in bed[/URL]
[QUOTE]The second stage will see the volunteers transferred to NASA’s Flight Analog Research Unit in Houston, Texas. They will spend 10 weeks lying in bed, with their bodies tilted slightly backwards, with their feet up and their head down.

Movement will be kept to a bare minimum, with the human lab rats only able to go to the toilet in a plastic bedpan, while they will also have to wash while lying down with a hand-held showerhead.

Reading and watching movies will be allowed, as these activates don’t use up much energy. However, the participants could suffer from aching joints, due to lying on one position for such a lengthy period of time.

The idea is to emulate what an astronaut’s body goes through during the weightlessness of space flight.[/QUOTE]

We're streaming... I already have a woody....

Edit: Shit! ~ T-3 minutes and the weather said "No Go".

Edit 2: I'm wondering... Could this be consider a geek's version of coitus interruptus?

Launch scrubbed because of bad weather slightly more than 3 minutes before launch.

I think you are right.
Ad astra: 99% per aspera and 1% ignition.
And there was no ignition.

[QUOTE]NASA originally shared:

SCRUB: Because of weather conditions that violated the rules for launching, SpaceX has postponed its planned launch of its Falcon 9 rocket carrying the Dragon spacecraft. It is SpaceX’s sixth commercial resupply services mission to the International Space Station.

The next launch opportunity is Tuesday, April 14, at 4:10:40 p.m. EDT. Our continuous launch coverage will begin at 3 p.m. Follow our launch blog: [url]http://blogs.nasa.gov/spacex[/url]

As for tomorrow’s forecast, it’s slightly worse tomorrow with forecasters predicting a 50 percent chance of acceptable conditions.[/QUOTE]
