The crew of shuttle mission STS-120 gather inside the Harmony module a day after it was attached to the International Space Station.

7 MISSIONS DOWN, 11 MORE TO GO... Of course, this excludes two as-yet unconfirmed contingency shuttle flights around 2009 or 2010. The orbiter Discovery touched down at Florida’s Kennedy Space Center at 10:01 AM, PST today...paving the way for one more shuttle flight in 2007 as Atlantis prepares for launch next month. Atlantis is now mated to its external fuel tank and twin solid rocket boosters, and will be rolled out to the launch pad on Saturday. Its cargo, the European Space Agency’s Columbus science module, arrived at the pad last night. With each completed mission, the International Space Station (ISS) continues to grow in size [except during next year's Hubble Space Telescope (HST) servicing mission... I'll get to that soon]. And yet sadly, each mission accomplished means the shuttle is getting closer to retirement 3 years from now...after 29 years of being America’s primary way of sending astronauts into space. Atlantis herself is scheduled for deactivation after she flies the very last servicing mission to HST in 2008 (this is the only remaining flight in the program where the shuttle won’t be going to the ISS). The third image below contains artwork depicting the shuttle’s replacement, the Orion Crew Exploration Vehicle, in its latest incarnation. Orion is scheduled to become operational no earlier than 2014, when it will initially be used to carry out logistical flights to the ISS. From 2016 on, however, the CEV will hopefully be utilized for what President Bush announced back in January of 2004: Returning humans to the Moon, and eventually setting the stage for a manned flight to Mars. Or at least a Near-Earth Asteroid. That last one seems a bit more doable right now. Somewhat.

UPDATE (November 10): Last flight of the year... Rolling out of the Vehicle Assembly Building around 1:43 AM PST this morning, space shuttle Atlantis was officially secured at the launch pad around 8:51 AM PST today. Its launch on mission STS-122 is still set for December 6.
