Baby is right around the corner.  The ultrasound tech just estimated the weight at 9 lb 3 oz.  I feel bad for my wife, that's a chunky baby.

I've been playing around with the Kerbal Space Program lately.  If you run the realism overhaul and real solar system mods it turns into a downright good space sim.  It also shows you just how hard it is to get into orbit and beyond, especially with people on board.  I think that if we're ever going to get off earth in a meaningful way, there's going to have to be a big breakthrough in our understanding of physics first.  The energy requirements and the sheer size of vehicle you need to get a payload into orbit just defy economics.

I did some thorough research on SpaceX's colonization plans.*  Supposedly their mars colonial transporter powered by their million pound thrust Raptor engine (x27 in three cores) will transport 100 colonists at a time to the surface of Mars.  Elon wants to put a million people there that way at $500K a ticket.  Let's do some math: The Saturn V (biggest rocket ever, except maybe the Energia but we won't go there) produced around 8 million pounds of thrust.  So... the MCT 'heavy' will be around 3.5x that size (20x the size of a Falcon 9).  At $500K a ticket, 100 colonists will pay $50 million dollars total for the flight.  That's less than the current price of a Falcon 9 launch.  I can only assume that Elon is counting on his fortune to grow... a lot between now and then to fund all of this.  Just goes to show you, Elon is really good at PR, sales, and latching onto big ideas.  He's not so good at reality sometimes.
