First TDRSS spacecraft in a decade set to launch on Atlas V this week

With lessons from fixed-price contracts, eyes smarter negotiations

As the development of Stratolaunch's Air Launch and Scaled Composites' WhiteKnightTwo carrier aircraft shows, the use of wing-borne platforms for delivering rockets to orbit is set to grow as the industry strives for lower launch costs. However, unlike the latest purpose-built air launchers, which build on the experience gained over the years of proven mothership vehicles such as the Boeing B-52 and Orbital Sciences' Lockheed L-1011, a newly unveiled NASA air launch concept differs in one major aspect in that it has no engines.

NASA's loss is Boeing's gain, as former space shuttle program manager John Shannon retires to head up the company's International Space Station program. “It is really great to be back in an operational program again,” Shannon says. Not so great for his space-agency bosses, who continue to see rising stars bail out while Congress and the White House squabble over NASA's future.

As the Boeing 787 fleet remains grounded due to safety issues with its lithium-ion batteries, the Joint Strike Fighter program office is not saying whether the issue will prompt any review of the F-35's electrical system, which incorporates a lithium-ion battery that is larger and higher-voltage than the 787's and has a once-per-sortie charge/discharge cycle. Made by a U.S. subsidiary of France's Saft, the JSF battery is the only onboard means of starting the fighter's integrated power pack, which starts the engine.

Simultaneous set of projects probes air pollution and climate change

Sized for space station modules, reconnaissance satellites

D. Brainerd Holmes, who led NASA's human spaceflight effort in the early 1960s, died Jan. 11 in Memphis, Tenn., of pneumonia. He was 91.
