On this morning 50 years ago, Naval pilot Alan Shepard, wearing his silver flight suit and white helmet, was raised by a small elevator to his waiting spacecraft, Freedom 7, perched atop a modified Redstone IRBM. Delays ensued at Cape Canaveral, as engineers and technicians raced to eliminate any glitch that popped up that would compromise the safety of the spacecraft's pilot. Shepard was getting weary of these holds to the countdown, and knowing his prowess as a test pilot, with a steely determination said, "Let's light this candle!" At 9:34am ET, the engine of the Redstone ignited, and America watched it's first astronaut ascend to space. 15 minutes later, the trip was over, with Freedom 7 safely parachuting to a landing in the Atlantic Ocean 300 miles away from the Cape. The astronaut and his spacecraft were recovered by aircraft carrier USS Lake Champlain, a welcome sight to Shepard.Thursday, May 5, 2011

Getting Ready for 30
Next week brings the 30th anniversary of the first launch of the space shuttle. Festivities are planned for the KSC Visitor Complex (weather and government shut-down permitting) at which Administrator Charlie Bolden will announce where these historical spacecraft will retire. Allow me to place my prediction in writing, and to be used as a reference once the decision is released.

My Kind of Town
Today I am in Chicago for a conference, so I took the afternoon to revisit some old friends. Chicago is one of the few places that host the trifecta of historical spacecraft, Mercury, Gemini, and Apollo. Interestingly, they are not found at the same location. While the Crown Space Center at the Museum of Science and Industry boasts Aurora 7 (Mercury) and the Apollo 8 Command Module, you have to travel up the lake front to the Adler Planetarium to see the Gemini 12 spacecraft.Monday, July 5, 2010
Some Fixes and a Titan Tale

On this fine holiday (observed) I was able to get in and fix some things in the Field Guide that had been creating some problems. There are still a few more things to work through but at least it looks nicer.

May I Ask?
A Field Guide to American Spacecraft has been a great hobby on mine over the last thirteen years, one that has introduced me to a lot of great friends and space enthusiasts from around the world. I am humbled each time I see it mentioned in a story or used as a reference, and that encourages me to continue and try to be as authoritative as possible. I hope to continue to provide this resource for many years.Saturday, June 12, 2010

Discovery Lands at KSC
Discovery is ten minutes away from landing here at KSC as I start writing this. Through the walls of the HQ building I have heard the jet rumble of the Shuttle Training Aircraft, a modified Gulfstream 5, which flies the route before landing to visually check on weather conditions. Specially equipped with flight-deployable air breaks it can 'hang' and drop in the same landing approach as the orbiter. The shuttle itself drops faster and steeper than a normal aircraft, so training orbiter pilots demands a novel test vehicle.
Here I go outside. More in a minute....
BOOM! BOOM!
And by the time I'm back at my desk, the orbiter is wheels stopped on Runway 33. A beautiful sight, as this approach brought the orbiter almost directly over HQ. Orbiter and crew now safe and sound on Terra Frima.
A few things to know about these events (and there are only three more left, so listen up!):
The two sonic booms are produced by shock waves emanating from the orbiter nose and tail.
After the booms, you can hear the sound of the orbiter cutting through the air, and possibly the APUs (auxillary power units). Which is what the booms are: the compressed sound waves of all the soundthat would normally precede the orbiter (this is a very rudimentary explaination).
The STA follows a minute behind the orbiter.
While thousands of people may come to the center to watch a launch, only a few hundred are invited to the landing site. The viewing area is close enough that, if hypergolic fuel is leaking from a valve in the reaction control system, evacuation must be immediate. Busses are left running in case of this emergency. It is also why you see the first responders dressed in the full emergency suits with airpacks.
Technically speaking, the orbiter does not 'fly' or 'glide' until the last 30 seconds or so when the nose elevates above the horizontal.. That is when the wings start producing lift. Everything before that is a 'controlled descent', or what my friend Buzz Lightyear refers to as "Falling with style!"
The drag produced by the creation of lift also rapidly drops the airspeed, threatening a stall. The art is to hold off the stall until touchdown on the runway.
Runway 33 and Runway 15 are the same runway. The numbers indicate the approach heading, 33 toward the north at heading 330ยบ, and 15 toward the south at heading 150ยบ.
Time to end this and post while it is still timely. While launches are magnificent, landings are exquisite. I would almost prefer to watch a landing. Guess I'll have to figure out how to get a ride with the Navy for the future.

Like a Norwegian Blue: Beautiful Plumage
This beautiful display has some serious science behind it. You all know that as the orbiter ascends, it is traveling through increasingly rarefied atmosphere, until it reaches a near vacuum at orbital altitude. You also know that the Space Shuttle Main Engines (SSME) works off of Newton's First Law of Motion, and the action of the exhaust leaving the engine bell produces the reaction of the engine and shuttle moving away. The exhaust does not need to 'push' against anything to produce thrust. While this is true, the exhaust does push against something, the gasses of atmosphere. At sea level, atmospheric pressure helps constrain the exhaust into the familiar plume we see.

Want a Shuttle?
Although this has sat off Florida State Route 3 south of Kennedy Space Center since 2005, I just now got around to posting it in the Field Guide. Being on my way to the office, I could see it every day. I remember noticing the large blue tarp covered structure and thinking it was shaped like a space shuttle nose, but it wasn't until after a bad storm when wind blew down the tarp that revealed what it was. One day, not long after the storm, a car was parked nearby and the gate was open. I met Chuck ryan, who began building the mockup as an engineering project while attending the California Polytechnic State University. He brought it out to Florida at the request of NASA to be used as an emergency trainer by the KSC Fire and Rescue Department. At the time I met Chuck, the site had flooded and I could not enter. But the tarp was replaced, occasionally being disarrayed by other wind storms.Wednesday, December 16, 2009
Spacecraft of the Week #14
A couple weeks ago we honored Gemini VII as the Spacecraft of the Week. This week, we do the same for its counterpart, Gemini VI. Due to the loss of its intended target vehicle, Gemini VI, crewed by Wally Schirra and Thomas Stafford, was delayed until after the long-duration mission of Gemini VII began. This was the first time Americans had two spacecraft in orbit simultaneously, and gave mission controllers crucial experience that would be needed by the Apollo missions.Monday, December 7, 2009
Spacecraft of the Week #13
This week we honor the final Apollo moon flight and make the Apollo 17 Command Module America the Spacecraft of the Week. Launched on Pearl Harbor day, December 7 in the year 1972, Apollo 17 was the most ambitious lunar mission to date. Carrying Gene Cernan, Ron Evans and Harrison Schmidt to the moon, America would remain in orbit with Evans while Cernan and Schmidt lived in the moon for three days. Many people call the "last" mission to the moon. I like to refer to it as the most recent. I refuse to believe that we will not again venture out into that "magnificent desolation". We can do it, if we have the will. And it will drive the economy up more than and faster than any stimulus package.Monday, November 30, 2009

Smithsonian Apollo Program Online Conference
Spacecraft of the Week #11
Gemini XII was launched with astronauts Jim Lovell and Buzz Aldrin on November 11 (Veterans Day) in 1966. The spacecraft in question was home to the astronauts for 4 days, during which Buzz Aldrin conducted three spacewalks. After an almost disastrous EVA on Gemini XI, Buzz helped engineer handholds and foot restraints and barely broke a sweat on his walk, indicating astronauts would be able to work outside the spacecraft landing on the moon. As the finale of the Gemini program it was a resounding success.The spacecraft was checked out after recovery at Johnson Space Center, and transported for display at the Museum of Transport and Technology in Aukland, New Zealand. After many years it returned to the states and was then placed for display at the Goddard Space Flight Center. It was paired at the Visitor Center there nose to nose with a sit-in model. Looking out the window while sitting in the model always reminded me of the Gemini VII - Gemini VI rendezvous in space. In 2005, the Smithsonian was asked to relocate the spacecraft.
The Adler Planetarium in Chicago had undergone a major renovation and wanted a 'capstone' to highlight man's relationship with space. Chicago native Jim Lovell was instrumental in bringing his old spacecraft to his hometown. No longer enclosed in a plexiglas cocoon, the capsule was placed in climate controlled display case designed and built by the Kansas Cosmosphere and Space Center. This new case is a prototype for future displays. Although it may somewhat restrict viewing and photography by boxing in the capsule, the importance of protecting the aging craft become paramount. Similar cases have been constructed for Gemini 3 , Gemini VI and Gemini X, Liberty Bell 7, and Apollo 13.
So to honor its history and for trailblazing a new way to preserve and display these important artificers, Gemini XII is our Spacecraft of the Week.
