The record-breaking balloon, carrying the Super Trans-Iron Galactic Element Recorder (Super-TIGER) experiment, has been afloat for 46 days and is on its third orbit around the South Pole.
"This is an outstanding achievement for NASA's Astrophysics balloon team," said John Grunsfeld, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. "Keeping these huge balloons aloft for such long periods lets us do forefront science that would be difficult to do otherwise."
Super-TIGER is flying a new instrument for measuring the rare heavy elements among the flux of high-energy cosmic rays bombarding the Earth from elsewhere in our Milky Way Galaxy. The information retrieved from this mission will be used to develop an understanding where these energetic atomic nuclei are produced and how they achieve their very high energies.
Super-TIGER launched Dec. 8, 2012, from the long duration balloon site near McMurdo Station, Antarctica. The massive 39-million cubic foot scientific balloon carries the 6,000 pound Super-TIGER payload -- equivalent to a large sports utility vehicle -- at a float altitude of 127,000 feet, more than four times the altitude of most commercial airliners. Size-wise, more than 200 blimps could fit inside the balloon.
The Super-TIGER flight shattered the previous record of 41 days and 22 hours, previously set in 2005. The Super-TIGER team plans to fly for another 8-10 days to have it fly closer to McMurdo Station before terminating the flight and recovering the experiment.
"It has taken eight years, but we are so excited about breaking the long duration balloon record. In addition, it looks like the Super-Tiger flight, which is still collecting science data, will raise the bar by a week or two," said Debora Fairbrother, chief of the Scientific Balloon Program Office at NASA’s Wallops Flight Facility in Virginia.
The long duration balloon site at Willy Field, McMurdo Station, takes advantage of the stratospheric anti-cyclonic wind pattern circulating from east to west around the South Pole. The stratospheric wind circulation combined with the sparsely populated continent of Antarctica allows for long duration balloon flights at altitudes above 100,000 feet.
The National Science Foundation Office of Polar Programs manages the U.S. Antarctic Program and provides logistic support for all U.S. scientific operations in Antarctica. The NSF Antarctic Support Contractor provides material support to the NASA Balloon Program, including support of launch and recovery operations throughout the Antarctic Campaign.
The principal investigator of the Super-TIGER mission is Dr. Walter Binns of Washington University, St. Louis, Mo.
NASA’s Columbia Scientific Balloon Facility in Palestine, Texas, is responsible for launch operations and command and control of the balloon during flight.To monitor the real time flight tracks of the long duration balloons on the Internet, visit:

Significantly more productivity in USP lasers

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
