HOUSTON — Astronauts Sunita Williams and Akihiko Hoshide will attempt to troubleshoot problems with an electrical unit outside the International Space Station during a Sept. 5 spacewalk organized over the U.S. Labor Day weekend.
CLUSTER DISCOVERY: Adding evidence to how diverse the universe is, NASA’s Kepler planet-hunting satellite has observed the first instance of multiple planets orbiting two suns, what astronomers call a circumbinary planetary system. The system, named Kepler-47, is 4,900 light years from Earth in the constellation Cygnus. One star is the size of the Sun but only 84% as bright; the other star is diminutive. The inner planet, Kepler-47b, has a radius three times the size of Earth and orbits the two stars in just 50 days, making its surface too hot for life.
HOUSTON — Step by step, the overarching elements of a human mission to a near-Earth asteroid are coming together at NASA’s Johnson Space Center (JSC), even though the needed hardware is still in development, timelines are hazy and budgets are uncertain.
MOTOR RUNNING: Alliant Techsystems (ATK) will perform a horizontal test-firing of their GEM-60 solid rocket motor on Sept. 6 at 11:15 a.m. MDT at the company’s facility in Promontory, Utah. The 43-ft.-long, 60-in.-dia. graphite epoxy motor will be cooled to 30F and will produce up to 270,000 lb. of thrust. The GEM-60’s fixed nozzle is needed to accurately test at the colder temperature. The nozzle, previously built by a supplier, is now built by ATK. A public viewing area will be available along route 83 North, approximately 20 mi. west of Corinne, Utah.
Huntsville company specializes in high-performance optical systems, including sensors and seekers, that exploit the phenomenon behind three-dimensional movies.
A United Launch Alliance Atlas 5 with a Centaur upper stage lifted NASA's twin Radiation Belt Storm Probe mission spacecraft into orbit Aug. 30 from Cape Canaveral on a two-year mission to study high-energy particle fluctuations within Earth's Van Allen radiation belts. The $686 million mission is expected to investigate how the belts respond to solar activity and influence space weather. The two 1,400-lb. probes were developed by the Johns Hopkins University Applied Physics Laboratory as part of NASA's Living with a Star initiative.
Germany's aerospace industry has been growing, driven by civil air transport demand. But it is facing difficult changes as its defense-related business contracts.
William G. Purdy cautioned in 1966 that society was on a path where affluence and regulation threatened to choke off interest in “unorthodox inquiries.”
If Neil Armstrong had written his own obituary, he likely would have said he had been a test pilot, an engineer, an educator and one of the 400,000 Americans who helped land the first humans on the Moon. Less important to him was the combination of experience and lucky career choices that placed him as the first person to reach the surface of a body beyond Earth.
HOUSTON — NASA’s twin Radiation Belt Storm Probe mission spacecraft thundered into Earth orbit atop an Atlas 5/Centaur upper stage combination early Aug. 30, initiating a $686 million, two-year mission for studies of high-energy particle fluctuations within the Earth’s Van Allen radiation belts, including their response to solar activity and influences on space weather. The United Launch Alliance rocket carrying the two 1,400-lb. probes lifted off from Space Launch Complex-41 at Cape Canaveral Air Force Station, Fla., at 4:05 a.m. EDT.
SOFIA FLIES: NASA’s Stratospheric Observatory for Infrared Astronomy (Sofia) is to begin its 2012-2013 mission series in November from Dryden Aircraft Operations Facility in Palmdale, Calif. Called Cycle 1, the science series will include 46 flights grouped in four multi-week observing campaigns. Sofia is a 747SP modified to carry a 100-in.-dia. infrared telescope.
