good morning all,
 I know for some of you today is your last day, not sure how much longer there will be any school but I will continue the news letter…..everything going great here, staying so busy with schools, even during the summer…my favorite time of the year…most people in Florida complain it is too hot but I love it…also swim training is great because the water is warm and the tanning is great…..wishing you a wonderful day...we have to remember to always do our best, enjoy everything we do, live in the present, make each day special, let those we care about most know, smile and have fun... Gabe

NASA TV to Broadcast U.S. Cargo Ship Departure from Space Station
 <http://www.nasa.gov/sites/default/files/thumbnails/image/25634985304_d6c7f6ee35_o.jpg>
The Orbital ATK Cygnus cargo ship is seen after final approach to the International Space Station. The vehicle was captured at 6:51 a.m. EDT March 26 using the space station's Canadarm2 robotic arm by Expedition 47 Commander Tim Kopra. The unmanned cargo craft was then bolted to the Earth-facing port on the Unity module at 10:52 a.m. Orbital ATK’s fifth cargo delivery flight under its Commercial Resupply Services contract delivered over 7,700 pounds of cargo and included equipment to support some 250 experiments during Expeditions 47 and 48.

After delivering almost 7,500 pounds of cargo to support dozens of science experiments from around the world, the Orbital ATK Cygnus cargo spacecraft is set to leave the International Space Station Tuesday, June 14. NASA Television will provide live coverage of Cygnus' departure beginning at 9 a.m. EDT. Ground controllers will detach the Cygnus spacecraft, which arrived at the station March 26, from the Earth-facing side of the station's Unity module using the Canadarm2 robotic arm. Robotics controllers will maneuver Cygnus into place and Expedition 47 robotic arm operators Tim Kopra of NASA and Tim Peake of ESA (European Space Agency) will give the command for its 9:30 a.m. release. Five hours after departure, the Saffire-I <https://www.nasa.gov/press-release/nasa-pursues-burning-desire-to-study-fire-safety-in-space> experiment will take place onboard the uncrewed cargo craft. Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions. Cygnus also will release five LEMUR CubeSats <http://www.nasa.gov/mission_pages/station/research/experiments/2349.html> from an external deployer June 15, part of a remote sensing satellite constellation that provides global ship tracking and weather monitoring. The vehicle will remain in orbit until Wednesday, June 22, when its engines will fire twice, pushing it into Earth's atmosphere where it will burn up over the Pacific Ocean. NASA TV will not provide a live broadcast of the Cygnus deorbit burn and re-entry. Experiments delivered on Cygnus <http://www.nasa.gov/mission_pages/station/research/news/crs6_science> supported NASA and other research investigations during Expeditions 47 and 48, including studies in biology, biotechnology, physical science and Earth science -- research that impacts life on Earth, and also will help us on the journey to Mars. Investigations studied realistic fire scenarios on a space vehicle, enabled the first space-based observations of meteors entering Earth’s atmosphere from space, explored how regolith behaves and moves in microgravity, tested a gecko-inspired adhesive gripping device <http://www.nasa.gov/jpl/gecko-grippers-moving-on-up> that can stick on command in the harsh environment of space, and added a new 3-D printer in microgravity. The Cygnus resupply craft launched March 22 <http://www.nasa.gov/press-release/nasa-sends-fire-meteor-experiments-to-international-space-station-on-commercial-cargo> on a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida, for the company’s fifth NASA-contracted commercial resupply mission.

Astronaut’s First Steps into BEAM Will Expand the Frontiers of Habitats for Space

On Monday, June 6, astronaut Jeff Williams will enter the first human-rated expandable module deployed in space, a technology demonstration to investigate the potential challenges and benefits of expandable habitats for deep space exploration and commercial low-Earth orbit applications. Williams and the NASA and Bigelow Aerospace teams working at Mission Control Center at NASA’s Johnson Space Center in Houston expanded the Bigelow Expandable Activity Module (BEAM) by filling it with air during more than seven hours of operations Saturday, May 28. The BEAM launched April 8 <https://www.nasa.gov/press-release/nasa-to-attach-test-first-expandable-habitat-on-international-space-station> aboard a SpaceX Dragon cargo spacecraft from Cape Canaveral Air Force Station in Florida, and was attached to the International Space Station’s Tranquility module about a week later. Williams’ entry will mark the beginning of a two-year data collection process. He will take an air sample, place caps on the now closed ascent vent valves, install ducting to assist in BEAM’s air circulation, retrieve deployment data sensors and manually open the tanks used for pressurization to ensure all of the air has been released. He will then install sensors over the following two days that will be used for the project’s primary task of gathering data on how an expandable habitat performs in the thermal environment of space, and how it reacts to radiation, micrometeoroids, and orbital debris. During BEAM's test period, the module typically will be closed off to the rest of the space station. Astronauts will enter the module three to four times each year to collect temperature, pressure and radiation data, and to assess its structural condition. After two years of monitoring, the current plan is to jettison the BEAM from the space station to burn up on re-entry into Earth’s atmosphere. Expandable habitats are designed to take up less room when being launched but provide greater volume for living and working in space once expanded. This first test of an expandable module will allow investigators to gauge how well the habitat performs and specifically, how well it protects against solar radiation, space debris and the temperature extremes of space. The BEAM is an example of NASA’s increased commitment to partnering with industry to enable the growth of the commercial use of space. The BEAM, which Bigelow Aerospace developed and built, is co-sponsored by Bigelow and NASA's Advanced Exploration Systems Division. The expansion process already has provided numerous lessons learned on how soft goods interact during the dynamic event of expansion. The module measured just over 7 feet long and just under 7.75 feet in diameter in its packed configuration. BEAM now measures more than 13 feet long and about 10.5 feet in diameter to create 565 cubic feet of habitable volume. It weighs approximately 3,000 pounds.

Veil Nebula Supernova Remnant

NASA's Hubble Space Telescope has unveiled in stunning detail a small section of the expanding remains of a massive star <http://www.nasa.gov/feature/goddard/hubble-zooms-in-on-shrapnel-from-an-exploded-star> that exploded about 8,000 years ago. Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan. This view is a mosaic of six Hubble pictures of a small area roughly two light-years across, covering only a tiny fraction of the nebula’s vast structure. This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun. The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.

8/16/2012 -- the last time for these two magnificent vehicles to meet on the tow way …I can say I was there…:-)
