                                                   						L2 or Bust!
                                                   Lockheed Martin's deep thinkers are back at it, proposing an 
Orion mission to the far side of the moon.  Some advantages:
- Astronauts on an L2-Farside mission would travel 15 percent farther
                                                      from Earth than the Apollo astronauts did - and spend almost three times longer in deep space.
- Each flight would prove
                                                      out the Orion capsule's life support systems for one-month duration missions before attempting a six-month-long asteroid mission.
- It
                                                      would demonstrate the high speed reentry capability needed for return from the moon or deep space 40 percent to 50 percent
                                                      faster than reentry from low-Earth orbit.
- The mission would measure astronauts' radiation dose from cosmic rays and solar
                                                      flares to verify that Orion provides sufficient protection, as it is designed to do. Currently the medical effects of deep
                                                      space radiation are not well understood, so a one-month mission would improve our understanding without exposing astronauts
                                                      to excessive risk.
Morning Update:  There's a fine line here.  I think this sort of mission is cool, as long as the Orion
                                                      does not serve to compete against commercial spacecraft doing the 'milk run' deliveries to the ISS and other LEO destinations.

                                                   						Physics and Engineering, Easy.  Bureaucracy, not so Much
                                                   In a few weeks, 
SpaceX will launch its first operational 
Dragon spacecraft into Earth orbit.  The launch will get a lot of attention (more if something goes wrong), but the much bigger
                                                      news, in my opinion, came 
on Monday, when the FAA issued its first license for a commercial company to return something from orbit.  A successful launch is simply
                                                      a triumph over physics and engineering which, while they are difficult, are predictable at their core.  Bureaucracy, with
                                                      its paperwork and approvals, is inherently unpredictable.  Fly Dragon, blaze a path for others to follow.

                                                       It's called, somewhat unimaginatively,

most recent episode ("Close Encounters of the Murderous Kind", no permalink) had a scene that involved Castle suddenly breaking into Chinese.

                                                   This picture deserves some serious recognition.  While it appears to have been enhanced a bit from the 
original, the sci-fi theme of an astronaut looking at their home will always have appeal.

                                                   						Blazing new Bureaucratic Frontiers
                                                   SpaceX moved the launch date for their first Dragon flight into December.  In the 
article, they say that 
Discovery's delays play a part, but that the FAA hasn't granted them a license for the reentry part
                                                      of their demonstration flight yet.  I'm assuming that future applications will go smoother, and thank SpaceX for their patience
                                                      to blaze the trail.

event that has a bunch of people worked up.  My initial impression is that it's much more likely to be a 
contrail than a missile The Pentagon didn't know about.  While there's talk about 'bright exhaust' (could be a reflection of the plane)
                                                      and 'moving way too fast' (appears to move faster when zoomed in) at 
this blog, without seeing the whole video, along with its zooms and changing angles, it's hard tell.

                                                   						Rediscovery:  Project Gemini History
                                                   I was reminded of a good book I read once: 
On the Shoulders of Titans:  A History of Project Gemini.  Luckily, it's also available 
online.  The history is part of a more involved 
Gemini history page.
                                                      
                                                      To me, Project Gemini is one of the great unsung moments of human spaceflight, when a small group of people took a project
                                                      from idea through completion in about 5 years for about $1.2B then-year dollars (about $6B of today's dollars...that's just
                                                      the NASA portion of the budget, but it's still less than NASA spent on Ares I alone before it was cancelled).  Who thinks
                                                      that could be done today?  Of course, there were some shortcuts taken, in that the capsule design was called an extension
                                                      of the Mercury capsule, allowing 
McDonnell Douglas to build it without a formal competition, and the 
Titan II was available, and could launch the capsule with minor improvements.  Amazing what some smart buying can do!
                                                      
                                                      Update:  In a recent trip to the 
National Museum of the United States Air Force, I came across 
this display of a 
Blue Gemini.  Wikipedia says that Blue Gemini and Gemini-B are different programs...may have to look into that.  It was supposed to be
                                                      part of the 
Manned Orbital Laboratory, and actually demonstrated the idea of piercing the heat shield of a capsule with a hatch.  I think that technology would
                                                      make the design of spacecraft much simpler, so that a crew capsule could actually fly atop their living quarters.

                                                   Looks like a 
fuel leak will keep 
Discovery's last mission from starting for a few weeks.  With the additional mission up in the air due to
                                                      
Congressional upheaval, that leaves one or two missions left for shuttles.  So, the 
sunset mission patch for 
Atlantis might have been drawn too early.
