Infrasound in the Stratosphere II Danny Bowman (Bovine Aerospace) 2015-05-13 | Infrasound recorded on a high altitude balloon during the 2014 HASP flight. The balloon floated at approximately 22 miles above sea level for 5.6 hours, travelling about 450 miles in the process. The research was featured in articles on Live Science and the Huffington Post as well as featured on the BBC and National Public Radio.The sound has been sped up 1000 times in order to bring it into the audible range. For a slower (and thus more detailed) version, see Infrasound in the Stratosphere I.

Halloween Solar Balloon Danny Bowman (Bovine Aerospace) 2014-10-31 | We haunt the skies with a scary, but not terribly buoyant, solar balloon on Halloween 2014.
Solar Balloon Lurks over UNC Danny Bowman (Bovine Aerospace) 2014-10-07 | We finally launch the flying pillowcase! I made this solar balloon over a year ago. It was supposed to be a tetroon, but I made a mistake somewhere down the line and it ended up being a lopsided rectangular prism. In any case, it still lifted four messages in bottles quite handily, and drifted overhead just as students were emerging from morning classes.
Slow Motion Dry Ice Explosions Danny Bowman (Bovine Aerospace) 2014-09-23 | We detonate 2 liter bottles full of water and dry ice and videotape them at 2000 frames per second.
First Launch in Solar Balloon Passive Tracking Experiment Danny Bowman (Bovine Aerospace) 2014-09-22 | We launch a 9' solar tetroon built by Mathew Lippincott. The balloon is carrying a message in a bottle, which we hope will someday be found. When we have a landing location, we can calculate possible trajectories based on the atmospheric wind profile on launch day.
Launching Candle Balloons Danny Bowman (Bovine Aerospace) 2014-02-16 | Launching two candle balloons in North Carolina. Step-by-step instructions on building this design can be found here: http://bovineaerospace.wordpress.com/2014/02/16/how-to-build-and-launch-candle-balloons
Field Solar Balloon Lift Test Danny Bowman (Bovine Aerospace) 2013-11-13 | A quick demonstration of a solar balloon designed for rapid deployment in the field (i. e. without electricity). The balloon lifted approximately 4 lbs during the test. The balloon is a 20' sphere of 0.31 mil clear painter's dropcloth gores taped together using packing tape. I ordered charcoal dust off of Amazon to turn it dark. The balloon has a 6' opening that can be cinched shut after inflation.
Landspout in Santa Fe, New Mexico Danny Bowman (Bovine Aerospace) 2013-07-23 | This video shows a rotating cloud associated with a brief landspout that occurred south of Santa Fe, New Mexico on July 21, 2013. A landspout is technically a weak tornado.About 10 minutes before the video was taken, we observed a brief but large whirlwind on the ground. Dust from this whirlwind ascended up to the base of the thunderstorm, and at that point we could see a rotating patch of cloud directly above us. The video shows this rotation in the lower center of the image. My apologies for the shakiness - I recorded it on my Android.
Near Space Flight over Snow Covered Desert Danny Bowman (Bovine Aerospace) 2013-05-15 | We launch a weather balloon carrying a camera above the New Mexico desert just after a snowfall on Christmas Eve 2011. Music:Psycoholic: Seventh UniversePsycoholic and Alfida: Sevgilim
Testing Balloon Mounted Infrasound Microphones using Oxyhydrogen Explosions Danny Bowman (Bovine Aerospace) 2013-04-12 | One challenge in the study of volcanic infrasound is to determine the acoustic radiation patterns above volcanic vents. I am combining my studies in volcano seismology with my experience flying large balloons to develop a vertical infrasound array in order to fill in this gap in our network coverage. If the array shown here can be scaled up, it will enable us to test different hypothesis on how infrasound is generated during volcanic eruptions.
Near Space Flight on Hydrogen Balloon Danny Bowman (Bovine Aerospace) 2013-04-12 | We fly a video camera and still camera to 24 kilometers (almost 15 miles) above central North Carolina, in our seventh tracked balloon launch. Our goals were to test our new GPS data logger through an entire flight as well as recover video. We ended up going for a very fast ascent rate because of a strong jet stream that could have dropped the payload in the ocean - as a consequence our maximum altitude (79,000 ft) is about 11,000 ft lower than we could have attained under better conditions.We launched in Saxapahaw and landed in Selma, North Carolina. Immediately after burst, the payload accelerated to 140 mph. It landed in a cotton field at approximately 30 mph - a little faster than intended because the plastic parachute fared poorly in the extreme altitude and cold.Here's a blog post with more details: bovineaerospace.wordpress.com/2013/06/02/a-hydrogen-filled-weather-balloon-flight-into-near-space
Triaxial Solar Balloon Tethering System Danny Bowman (Bovine Aerospace) 2013-03-11 | Testing how three points of contact work for a tethered balloon system. In about a month I will be attempting a much larger version of this with a helium balloon about 30 meters in the air.The three strings kept the balloon fairly stable in low wind. The movable anchor points (cinder blocks, in this case) were great because I could change the tether configuration pretty easily.For more info on my solar balloon projects, see the other videos on this channel and check out my blog at bovineaerospace.wordpress.com
Above the Clouds in Minnesota (Camera on Weather Balloon) Danny Bowman (Bovine Aerospace) 2013-03-06 | We send a weather balloon with a camera to ~30,000 ft above the snow-covered Minnesota landscape. This was our 6th balloon launch (designated Jake 6) and was designed to test a balloon cut down system. Though the camera's memory ran out due to a faulty setting, our cut down worked perfectly, sending the payload back to earth once the balloon reached 60,000 ft. Details on the launch will be posted soon on bovineaerospace.wordpress.com.Music:Psycoholic - Light Years Ahead
Santiaguito Volcano: Explosions, Earthquakes, and Rockfalls Danny Bowman (Bovine Aerospace) 2012-11-22 | Volcanic eruptions, rockfalls, and an earthquake on Santiaguito volcano in Guatemala. Santiaguito is an actively erupting volcanic dome complex built in the crater left by the cataclysmic 1902 eruption of Santa Maria volcano.
Successful Solar Balloon Launch Danny Bowman (Bovine Aerospace) 2012-11-04 | Bovine Aerospace launches a 10' paint dropcloth solar balloon carrying 3 messages in bottles. Balloon was launched in North Carolina in October 2012. As of November, no bottles have been found.I will be posting a description of the balloon and the launch on my blog soon.

Giant Solar Balloon Launch Danny Bowman (Bovine Aerospace) 2012-05-26 | We launch a 20 ft diameter solar balloon from Norwood, Massachusetts, carrying 9 bottles with messages in them for dispersal into the Atlantic Ocean. The launch is designated Jake III, and took place at about 6:15 AM on May 18th. The balloon was tracked via the Instamapper app for about an hour as it ascended to 9,000 ft and drifted to the Southeast, with a final known ascent rate of 300 ft/min. After that, we lost tracking-but it likely flew for 13 more hours and probably reached an altitude in excess of 50,000 ft. We believe it landed several hundred miles offshore, releasing the bottles via the dissolution of a melted sugar seal.The balloon was easily visible at over 10,000 ft, and was witnessed by at least one group of people other than us. I've posted launch and construction details on my blog. Read all about it here:http://bovineaerospace.wordpress.com/2012/05/26/jake-iii-the-successful-launch-of-a-20-ft-solar-balloonThis balloon is in memory of Jake, my friend's dog, whose irascible manner inspired us to name each launch after him. Jake died of stomach problems last night. We hope he is in a better place now-one with legions of squirrels and not a tree in sight.
