And now we have the "wool meter." Speaking of taxi-meters, yardsticks, and other measuring devices, the "wool meter" has been introduced by the Bureau of Standards. Described by the forbidding name "eriometer," this new instrument is intended to measure the diameter of wool fibers and thus indicate the relative qualities of the fleece entering into our wool clothes. H.J. McNicholas of the Textile Section is shown with his invention, which employs the principle of diffraction of light

Bureau of Standards designs mechanical batter to determine liveliness of baseballs. Washington, D.C., Feb. 21. Using a newly designed apparatus, the U.S. Bureau of Standards today began experiments to determine the relative home-run qualities of American, National and International baseballs. In conducting the tests a scientist pulls the trigger of an air gun loaded with a wooden projectile representing the slugger's bat. The projectile strikes a baseball causing it to fly toward a ballistic pendulum. After each of such hits the scientist takes a reading on the pendulum. It tells him how hard the ball hit the pendulum, or whether it was a homerun, a double, [...]st a pop fly. Dr. H.L. Dryden, Chief [...]e Division of Mechanics and Sound, Designed the machine and is supervising the tests. He is [...] right while on the left is Edward B.

KENNEDY SPACE CENTER, FLA. -- The shuttle training aircraft, or STA, moves toward the runway on NASA's Shuttle Landing Facility. In the cockpit are STS-120 Commander Pamela Melroy and Pilot George Zamka, who will begin landing practice on the runway. A modified Grumman American Aviation-built Gulf Stream II jet, the STA simulates an orbiter's cockpit, motion and visual cues and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Melroy and other crew members are at Kennedy Space Center to take part in the terminal countdown demonstration test, which also includes a simulated launch countdown. Mission STS-120 is targeted for Oct. 23. Photo credit: NASA/Kim Shiflett KSC-07pd2693

CAPE CANAVERAL, Fla. –At the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, STS-128 Pilot Kevin Ford walks away from the Shuttle Training Aircraft, or STA, after completing shuttle landing practice. The practice is in preparation for launch of space shuttle Discovery's STS-128 mission in late August to the International Space Station. The STA is a Grumman American Aviation-built Gulfstream II jet that was modified to simulate a shuttle’s cockpit, motion and visual cues, and handling qualities. The STS-128 crew is at Kennedy for a launch dress rehearsal called the terminal countdown demonstration test, or TCDT, which includes emergency exit training and equipment familiarization, as well as a simulated launch countdown. Discovery will deliver 33,000 pounds of equipment to the station, including science and storage racks, a freezer to store research samples, a new sleeping compartment and the COLBERT treadmill.

KENNEDY SPACE CENTER, FLA. -- STS-116 Commander Mark Polansky is ready to begin practice flights on the shuttle training aircraft (STA) three days before launch. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. Launch of Space Shuttle Discovery on mission STS-116 is scheduled for 9:35 p.m. Dec. 7. On the mission, the STS-116 crew will deliver truss segment, P5, to the International Space Station and begin the intricate process of reconfiguring and redistributing the power generated by two pairs of U.S. solar arrays. The P5 will be mated to the P4 truss that was delivered and attached during the STS-115 mission in September. Photo credit: NASA/Kim Shiflett KSC-06pd2649

KENNEDY SPACE CENTER, FLA. - STS-115 Commander Brent Jett settles in the cockpit of the Shuttle Training Aircraft to practice landing the shuttle. STA practice is part of launch preparations. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter’s cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter’s atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. Mission STS-115 is scheduled to lift off about 12:29 p.m. Sept. 6. Mission managers cancelled Atlantis' first launch campaign due to a lightning strike at the pad and the passage of Tropical Storm Ernesto along Florida's east coast. The mission will deliver and install the 17-and-a-half-ton P3/P4 truss segment to the port side of the integrated truss system on the orbital outpost. The truss includes a new set of photovoltaic solar arrays. When unfurled to their full length of 240 feet, the arrays will provide additional power for the station in preparation for the delivery of international science modules over the next two years. STS-115 is expected to last 11 days and includes three scheduled spacewalks. Photo credit: NASA/Kim Shiflett KSC-06pd2027

A Shuttle Training Aircraft (STA) taxis into the parking area of KSC's Shuttle Landing Facility. The STA is a modified Grumman American Aviation-built Gulfstream II executive jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. It is used by Shuttle flight crews to practice landing the orbiter. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. The orbiter differs in at least one major aspect from conventional aircraft; it is unpowered during re-entry and landing so its high-speed glide must be perfectly executed the first time there is no go-around capability. The orbiter touchdown speed is 213 to 226 miles (343 to 364 kilometers) per hour. There are two STAs, based in Houston KSC-00pp0604

The crew will deliver and install the P3/P4 segment to the port side of the integrated truss system on the International Space Station. The truss includes a new set of photovoltaic solar arrays. When unfurled to their full length of 240 feet, the arrays will provide additional power for the station in preparation for the delivery of international science modules over the next two years.

Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. Mission STS-115 is scheduled to lift off about 4:30 p.m. Aug. 27. The crew will deliver and install the P3/P4 segment to the port side of the integrated truss system on the International Space Station. The truss includes a new set of photovoltaic solar arrays. When unfurled to their full length of 240 feet, the arrays will provide additional power for the station in preparation for the delivery of international science modules over the next two years. The mission is expected to last 11 days and includes three scheduled spacewalks. Photo credit: NASA/Kim Shiflett KSC-06pd1907

KENNEDY SPACE CENTER, FLA. - STS-115 Pilot Christopher Ferguson settles in the cockpit of the Shuttle Training Aircraft to practice landing the shuttle. STA practice is part of launch preparations. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter’s cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter’s atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. Mission STS-115 is scheduled to lift off about 4:30 p.m. Aug. 27.
