Quarry in Tow, Stardust Begins Long Journey Home - Space.com  Stardust is on its way home with its quarry -- comet particles some 4.5 billion years old -- in tow. After a five-year journey covering nearly 3.2 billion kilometers, the NASA sample-grabber finally closed Jan. 2 on the object of its pursuit, the Comet Wild 2 (pronounced “Vilt 2”). At 2:40 P.M. EST, the 5.4-kilometer wide comet zoomed past Stardust at nearly 22,000 kilometers per hour, passing within 300 kilometers of the spacecraft.

Bush proposal to send man to Mars  - BBC  President George W Bush will announce proposals next week to send Americans to Mars, and back to the Moon. Senior US officials say he will also reveal plans for the construction of a permanent lunar space station. Correspondents say Mr Bush had been expected to propose a bold new space mission as part of his re-election campaign. The president's father proposed men be sent to Mars when he was in office in 1989 but the project went nowhere due to cost. Sources say George W Bush will encourage scientists to prepare for the mission in a decade's time, allowing the costs to be spread over a number of years.

Fresh fears over men's fertility  - BBC  Men's sperm counts have fallen by almost a third since 1989, one of the largest studies of its kind has found. The findings add to the evidence which suggests a growing number of men may have problems fathering children. Researchers in Aberdeen said their findings, based on 16,000 semen samples taken from 7,500 men, "cause concern". Scientists said that while the fall may be a result of more men coming forward for treatment, further investigation was needed. They are now carrying out studies to find out if there has been a similar decrease in sperm quality, which can significantly reduce a man's chances of having children naturally.
