Government scientist cools water to -6ʺ without freezing it. Washington, D.C., Aug. 9. The belief that water freezes at 32 degrees fahrenheit has been blasted by Dr. N. Ernest Dorsey, scientist of the National Bureau of Standards. Neither does all water freeze at the same temperature. These discoveries have been made by Dr. Dorsey after experimenting with 37 specimens of water taken from lakes, canals, and other sources. He has cooled water until it was minus 6 degrees fahrenheit that is, 38 degrees colder that the so called freezing point of 32 degrees. Yet it remained liquid, 8/9/38

"Why is an Earthquake" Washington, D.C., Dec. 17. The old question "why is an earthquake," and many other geological mysteries important to man, are being probed by scientific gadgets such as the two pictured here at the Geological Laboratory of the Carnegie Institute. The scientists work and apparatus will be studied by geologists from all points of the country when the Geological Society of America meets in Washington December 28-30. Dr. J.F. Schairer, physical chemist of the laboratory is shown at the instrument panel of one of t he cylindrical electrical furnaces which generate heat up to 2100 degrees Fahrenheit, melting artificial rock in the study of crystallization or cooling of rocks from volcanoes. 12/17/37

KENNEDY SPACE CENTER, FLA. - Workers in KSC's Vertical Processing Facility lower the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) into the Second Axial Carrier. NICMOS is one of two new scientific instruments that will replace two outdated instruments on the Hubble Space Telescope (HST). NICMOS will provide HST with the capability for infrared imaging and spectroscopic observations of astronomical targets. The refrigerator-sized NICMOS is HST's first cryogenic instrument -- its sensitive infrared detectors must operate at very cold temperatures of minus 355 degrees Fahrenheit or 58 derees Kelvin. NICMOS will be installed in Hubble during STS-82, the second Hubble Space Telescope servicing mission. Liftoff is targeted Feb. 11 aboard Discovery with a crew of seven.

US Air Force STAFF Sergeant Paul Fung of the 305th Aircraft Generation Squadron operates the AirPlus, a new de-icing system developed by the Air Force Research Laboratory. The AirPlus produces a high-velocity air-jet by drawing ambient air into a compressor. The air then exits the compressor at 13 pounds per square inch and heated to 100 degrees Fahrenheit. Once the air reaches the nozzle, it returns to its ambient temperature and pressure, a process of converting thermal energy into kinetic energy. Some of the advantages are the use of air rather than glycol as the major de-icing medium. The air is diffused slowly from the nozzle for increased coverage and the minimum use of glycol ...

CAPE CANAVERAL, Fla. – In the tile shop at NASA's Kennedy Space Center, a worker reaches for the door to close the oven with the Boeing Replacement Insulation 18, or BRI-18, tile inside. The tile will be baked at 2,200 degrees Fahrenheit to cure the ceramic coating, part of the process to prepare the tiles for installation on space shuttles. BRI-18 is the strongest material used for thermal insulation on the orbiters and, when coated to produce toughened unipiece fibrous insulation, provides a tile with extremely high-impact resistance. It is replacing other tiles on areas of the vehicle where impact risk is high, such as the landing gear doors, the wing leading edge and the external tank doors.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, space shuttle Endeavour arrives at Launch Pad 39A during uncustomary conditions -- ice floating in the standing water inside the perimeter fence. The ambient air temperature during Endeavour's 3.4-mile trip from the Vehicle Assembly Building to the pad ranged from 30 to 40 degrees Fahrenheit. First motion for the move, known as rollout, was at 4:13 a.m. EST Jan. 6. Endeavour was secure or "hard down" on the pad at 10:37 a.m. Rollout is a significant milestone in launch processing activities. The primary payload for the STS-130 mission is the International Space Station's Node 3, Tranquility, a pressurized module that will provide room for many of the station's life support systems. Attached to one end of Tranquility is a cupola, a unique work area with six windows on its sides and one on top. The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency. Endeavour's STS-130 launch is targeted for 4:39 a.m. EST Feb. 7.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, space shuttle Endeavour slowly rolls through the open doors of the Vehicle Assembly Building's High Bay 1 into the night air with temperatures just above 30 degrees Fahrenheit. First motion out of the bay was at 4:13 a.m. EST Jan. 6. The 3.4-mile trip to Launch Pad 39A, known as rollout, takes about six hours. Rollout is a significant milestone in launch processing activities. The primary payload for the STS-130 mission is the International Space Station's Node 3, Tranquility, a pressurized module that will provide room for many of the station's life support systems. Attached to one end of Tranquility is a cupola, a unique work area with six windows on its sides and one on top. The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, icicles hang from the railing at Launch Pad 39A as space shuttle Endeavour reaches the pad. The temperature during Endeavour's 3.4-mile trip from the Vehicle Assembly Building to the pad ranged from 30 to 40 degrees Fahrenheit. First motion for the move, known as rollout, was at 4:13 a.m. EST Jan. 6. Endeavour was secure or "hard down" on the pad at 10:37 a.m. Rollout is a significant milestone in launch processing activities.

CAPE CANAVERAL, Fla. -- In Orbiter Processing Facility-1 at NASA's Kennedy Space Center in Florida, a thermal protection system technician has secured a newly installed heat shield tile in place under space shuttle Atlantis with a pressure fitting to ensure a tight bond. The tiles are part of the Orbiter Thermal Protection System, thermal shields to protect against temperatures as high as 3,000 degrees Fahrenheit, which are produced during descent for landing. Atlantis is being prepared for the STS-135 mission, which will deliver the Raffaello multi-purpose logistics module packed with supplies, logistics and spare parts to the International Space Station.
