The Problem with Gravity: New Mission Would Probe Strange Puzzle - Space.com  more than a decade ago a researcher noticed something funny about two Pioneer spacecraft that were streaming toward the edge of the solar system. They weren't where they should have been. Something was holding the probes back, according to calculations of their paths, speed and how the gravity of all the objects in the solar system-- and even a tiny push provided by sunlight -- ought to act on them.     
China Marks Anniversary Of Its First Atomic Bomb - SpaceDaily  Left: China successfully detonated its first atomic bomb in the western part of the country on October 16, 1964 at 3 p.m. Photo credit: Xinhua News Agency. Chinese scientists, army veterans and students Saturday commemorated the 40th anniversary of the explosion of the country's first atomic bomb. At a commemorative forum in Malan of northwest China's Xinjiang Uygur Autonomous Region- a place that served as the country's nuclear experiment base 40 years ago- General Xu Ruichen, a retired army official of national defense who once worked at the base, said that China's decision to develop atomic bomb was of great historical significance at a time when the country was put under an adverse international environment. In Beijing-based Qinghua University, students were urged to learn from scientists who devoted themselves to the country's nuclear programs.   

One Wee Hop For A Laser 'craft' Might Also Be A Giant Leap - SpaceDaily  Left:  This almost imperceptible hop on June 7, 2004, was the first laser-fired 'rocket' launch in a vacuum.

But the half-millimeter hop of a tiny plastic "craft" in a UAH lab this summer might turn out to be a giant leap in the history of rockets. As part of a NASA-funded research project, UAH's Laser Propulsion Group is studying what has now become a new type of rocket engine. This laser "ablation" technology is also efficient, with each pound of material generating five to ten times as much thrust as a pound of chemical rocket fuel and oxidizer.
