SpaceX Launches Six Commercial Satellites on Falcon 9; Landing Test Ends in “Kaboom”

SpaceX Launches Six Commercial Satellites on Falcon 9; Landing Test Ends in “Kaboom”:

SpaceX successfully launched six ORBCOMM advanced telecommunications satellites into orbit on Monday, July 14, to significantly upgrade the speed and capacity of their existing data relay network. The launch had been delayed or scrubbed several times since the original launch date in May due to varying problems from payload integration issues, weather conditions and issues with the Falcon 9 rocket. But the launch went off without a hitch today and ORBCOMM reports that all six satellites have been successfully deployed in orbit.

SpaceX also used this launch opportunity to try and test the reusability of the Falcon 9?s first stage and its landing system while splashing down in the ocean. While SpaceX CEO Elon Musk reported that the rocket booster reentry, landing burn and leg deployment worked well, the hull of the first stage “lost integrity right after splashdown (aka kaboom),” Musk tweeted. “Detailed review of rocket telemetry needed to tell if due to initial splashdown or subsequent tip over and body slam.”

SpaceX wanted to test the “flyback” ability to the rocket, slowing down the descent of the rocket with thrusters and deploying the landing legs for future launches so the first stage can be re-used. These tests have the booster “landing” in the ocean. The previous test of the landing system was successful, but the choppy seas destroyed the stage and prevented recovery. Today’s “kaboom” makes recovery of even pieces of this booster unlikely.

As far as the ORBCOMM satellites, the six satellites launched today are the first part of what the company hopes will be a 17-satellite constellation. They hope to have all 17 satellites in orbit by the end of the 2014.

NASA Photos Photography

The National Aeronautics and Space Administration (NASA) is the United States government agency responsible for the civilian space program as well as aeronautics and aerospace research. President Dwight D. Eisenhower established the National Aeronautics and Space Administration (NASA) in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.

UFO SIGHTINGS PHOTO PHOTOGRAPHY

The Oxford English Dictionary defines a UFO as "An unidentified flying object; a 'flying saucer'." The first published book to use the word was authored by Donald E. Keyhoe. The acronym "UFO" was coined by Captain Edward J. Ruppelt, who headed Project Blue Book, then the USAF's official investigation of UFOs. He wrote, "Obviously the term 'flying saucer' is misleading when applied to objects of every conceivable shape and performance. For this reason the military prefers the more general, if less colorful, name: unidentified flying objects. UFO (pronounced Yoo-foe) for short." Other phrases that were used officially and that predate the UFO acronym include "flying flapjack", "flying disc", "unexplained flying discs", "unidentifiable object", and "flying saucer". The phrase "flying saucer" had gained widespread attention after the summer of 1947. On June 24, a civilian pilot named Kenneth Arnold reported seeing nine objects flying in formation near Mount Rainier. Arnold timed the sighting and estimated the speed of discs to be over 1,200 mph (1,931 km/h). At the time, he described the objects' shape as being somewhat disc-like or saucer-like, leading to newspaper accounts of "flying saucers" and "flying discs". In popular usage the term UFO came to be used to refer to claims of alien spacecraft. and because of the public and media ridicule associated with the topic, some investigators prefer to use such terms as unidentified aerial phenomenon (or UAP) or anomalous phenomena, as in the title of the National Aviation Reporting Center on Anomalous Phenomena (NARCAP).

UFO - Unidentified Flying Object An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. Culturally, UFOs are associated with claims of visitation by extraterrestrial life or government-related conspiracy theories, and have become popular subjects in fiction. While UFOs are often later identified, sometimes identification may not be possible owing to the usually low quality of evidence related to UFO sightings (generally anecdotal evidence and eyewitness accounts). Stories of fantastical celestial apparitions have been told since antiquity, but the term "UFO" (or "UFOB") was officially created in 1953 by the United States Air Force (USAF) to serve as a catch-all for all such reports. In its initial definition, the USAF stated that a "UFOB" was "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." Accordingly, the term was initially restricted to that fraction of cases which remained unidentified after investigation, as the USAF was interested in potential national security reasons and/or "technical aspects" (see Air Force Regulation 200-2). During the late 1940s and through the 1950s, UFOs were often referred to popularly as "flying saucers" or "flying discs". The term UFO became more widespread during the 1950s, at first in technical literature, but later in popular use. UFOs garnered considerable interest during the Cold War, an era associated with a heightened concern for national security. Various studies have concluded that the phenomenon does not represent a threat to national security nor does it contain anything worthy of scientific pursuit (e.g., 1951 Flying Saucer Working Party, 1953 CIA Robertson Panel, USAF Project Blue Book, Condon Committee).
