By 2000, the commercial business will be well on its way to becoming the dominant part of the space sector. Before the first decade of the 21st century is out, commercial space sales will eclipse both military and civil space agency purchases.
A Russian ``Photon'' Vostok-class spacecraft carrying dozens of European experiments was heavily damaged Mar. 3 when a military helicopter carrying the vehicle after recovery was forced to drop the several-ton satellite. The 13,640-lb. Photon 10 was launched from Plesetsk Cosmodrome Feb. 16 for a two-week commercial microgravity mission that ended Mar. 3 with its reentry and parachute landing 135 km. (83 mi.) southeast of Orenberg near Russia's border with Kazakhstan.
Global sales in the civil side will continue to decline in 1995, following ongoing production cutbacks at the major aircraft manufacturers. However, as late 1996 or early 1997 approaches, the industry may begin to crawl out of the slump caused by the continued imbalance between available seats and demand. Despite the potential for recovery, cost pressures will remain in the manufacturing and air transport arenas and could slow a recovery.
WASHINGTON Pressing need for a beyond-visual-range multirole fighter drives modernization of China's air force and draws Israeli technology support U.S. defense officials are circulating drawings within the Pentagon of the proposed next-generation F-10 Chinese fighter that show a relatively compact multi-role aircraft resembling a cross between the U.S.-built F-16 and Israeli-built Lavi.

SCIENTISTS AT LOS ALAMOS (N.M.) National Laboratory are interested in commercializing a directed laser fabrication process that requires no mold, pattern or die to form dense, complex parts. The procedure could speed component prototyping dramatically as shape changes require only modifying the part's digital, three-dimensional model on computer-assisted design software. The automated, single-step process uses a focused laser to fuse metal or composite powders that are gas-fed into the beam spot, according to Gary K. Lewis of LANL's Materials Science and Technology Div.
