The AA for S&MA stated that he would defer to Shuttle management in handling such a request. The JSC manager for Shuttle Safety program said he was told this was an “in-family” event – meaning it was normal and nothing to worry about. Seven days into the mission, a NASA Headquarters Safety and Mission Assurance (S&MA) manager called a JSC S&MA manager for the Shuttle Safety Program and the Associate Administrator (AA) for S&MA, to discuss a potential DoD imaging request. The imaging request was viewed by Shuttle Program Managers as a non-critical engineering desire rather than a critical operational need. The DAT assigned the NASA Co-Chair to pursue a request for imagery of the vehicle on-orbit – constituting the third request for imagery – by going through the Engineering department rather than through Shuttle Program Managers. The assumptions and uncertainty incorporated in this analysis were never fully presented to the Mission Management Team (MMT). Because foam is less dense than ice, the DAT used a qualitative extrapolation of the test data and engineering judgment that a foam impact angle of up to 21° would not penetrate the RCC. Crater was classified as a “conservative” tool based on its projections of ice projectile damage to RCC turning out to be more severe than that achieved experimentally. Crater was suitable for small debris impacts, on the order of 49cm3 – versus 19,665cm3, the estimated size of the bipod ramp foam. Without additional on-orbit pictures, the DAT was restricted to using a mathematical modeling tool called Crater, that predicts the depth to which debris will penetrate a Thermal Protection System (TPS) tile. The first formal DAT meeting was held on January 21st, five days into the mission.Ī trajectory analysis that used a computational fluid dynamics approach to determine the likely position and velocity histories of the foam (Credits: NASA Ref p61). The Department of Defense (DoD) Manned Space Flight Support Office began implementing the request, albeit with the assurance from MCC that this was merely information gathering, not a formal request for action. DAT contractor engineers prompted a NASA Shuttle manager to make a second imagery request. The Program Manager agreed to explore the possibility – this was the first imagery request of the mission.Ī Debris Assessment Team (DAT) was formed with NASA and contractor engineers. On the second day of the mission, the Intercenter Photo Working Group Chair contacted the Shuttle Program Manager for Launch Integration at KSC to request imagery of Columbia’s left wing on-orbit. – In the video below, the apparently trouble-free launch of Columbia STS-107. Columbia continued its 16 day mission without further incident – until Entry Interface. MCC also emailed a short video clip of the foam strike. MCC stated there was “ absolutely no concern for entry” because the phenomenon had been seen before. On flight day eight, MCC emailed the crew that post-launch photo analysis showed External Tank foam had struck the orbiter’s left wing during ascent. Neither the crew nor MCC were aware that on flight day two an Air Force Command review of radar tracking data detected an object drifting away from the orbiter, that subsequent analysis suggested may have been related to the foam strike. The analysis revealed that the debris was approximately 53-68cm long and 30-45cm wide, tumbling and moving at a relative velocity of 670-922km/h at the time of impact. The impact was detected the next day during the detailed review of all launch camera photography that is conducted after every Shuttle launch. This incident was not seen by anyone on the ground or in the Kennedy Space Center (KSC) Firing Room or Johnson Space Center (JSC) Mission Control Center (MCC) there was no onboard indication to the crew. The foam impacted under the leading edge of the left wing at 81.9 seconds. At 81.7 seconds after launch, when the Shuttle was at about 20,000m and traveling at Mach 2.46 (2,655km/h), a large piece of insulating foam came off the External Tank (ET) left bipod ramp area, close to where the orbiter attaches to the ET. The Space Shuttle Columbia STS-107 was launched on Januat 10:39 a.m. This article presents a technical overview of the accident, its cause, and the post-flight consequences. The Space Shuttle Columbia disaster is one of the most tragic chapters of spaceflight history.

There’s plenty of data in this dataset to splice and dice. NextĪre you a data-nerd and like pinball? Stay tuned. I tweaked the distance decay parameters a bit to get a heat map that made sense for the distribution of my points and the area of interest (i.e., the entire U.S.). I simply put the x,y coordinates of all the pinball locations with a count of pinball machines in each establishment as the “heat” value. Chris Love put together a really useful macro to do nearly all the work here. Alteryx is an excellent spatial data tool, and it’s possible to set up the heat map data in Alteryx to display in Tableau. Though, the data prep can be a little cumbersome, even in traditional GIS tools. Heat maps are fun and a good way to visualize relative geographic distribution of a phenomena. This download is real handy if you need quick access to 2010 Census tables and geometry but don’t want to mess around with Census American Factfinder. For you Alteryx users out there, you don’t need the spatial data package to access 2010 Census data with their Allocate tools. I also use Metropolitan Statistical Areas for my unit of analysis. In the viz, I calculate pinball machines per capita, which requires the inclusion of Census population data. Clip the points to the boundary of the U.S.Spatial match (or spatial join in the GIS world) the pinball locations to Census CBSA’s to bring in population data and provide a geographic unit of analysis.Cross tabulate the data to get a unique record for each pinball machine.Point to the directory with the 93 JSON files and union together with Alteryx’s Wildcard feature inside the Input tool.I needed to spatial join (or spatial match) pinball locations to Census geometry and population values.The JSON format played well the Alteryx’s JSON parser.Here’s what that looks like:īy all means, the data could be prepped in Python. Though, for a few reasons, I turned to my favorite data Swiss army knife, Alteryx. So, I wrote a quick python script to find all the regions and programmatically download all regions. I could take the time to download each region manually, but that’s way too much work. The data is divided into 93 separate regions, which can be individually downloaded. I used a combination of Python and Alteryx for the data prep – Python to get the data and Alteryx for the rest.
Sometimes that hammer is just out of reach, and you really need to bump a stud over a bit to get it to line up properly. Metal Strike PlatesĪnyone that has been out in the field long enough knows that you do not always have the right tool at hand for the job. The lightweight tools quickly became favorites because they felt nimble, especially when having to do overhead work or anything that involved using the tool for hours at a time. All the nailers tended to have a slight bias toward the head of the tool when holding onto the handle, and this is to be expected given the tool’s shape-and the fact that you want the weight to be on the striking side. A very close second and third lightest goes to the Max SuperFramer SN883HR2 (7.47 lbs.) and the GripRite GRTFR83 (7.49 lbs.) Porter-Cable’s FR350MAG, despite its large size, is also a good choice since it is in the sub-eight pound range.īalance goes hand in hand with weight, and as you can imagine, lighter overall weight typically resulted in better balance. The heaviest was the Makita AN923 at 9.4 pounds, and the lightest was the Hitachi NR90AE (S) at just 7.37 pounds. There was just over a two pound spread in the weight of the ten nailers in this review. Since each manufacturer submitted only one product for review it should be easy to follow what tool we are talking about-plus you can think of it as being on a first-name basis.įollowing is a breakdown of what I consider to be major features of pneumatic framing nailers. As I work through this list of feature sets, I will typically just call out the model number once per product and then refer to just the brand names of the associated tool. Where the differences start to play out is in how the tools implement these and other features. A trigger is used to activate the firing of the nail with each having some method to change from bump (contact) mode to sequential fire modes.Each has a sliding safety system built right into the contact tip with some means of depth adjustment.
