A new nuclear arms control treaty signed by the United States and Russia in April would not limit future U.S. plans for missile defense, key military brass said yesterday

Russian Prime Minister Vladimir Putin has approved an initiative to improve the testing capacity for the nation's nuclear arsenal.

The U.S. Air Force's secretive X-37B space plane may eventually get some company in low-Earth orbit as other countries such as Italy and Russia push forward with plans for their own reusable winged spaceships.

Russia is considering a plan to launch a spacecraft capable of moving a huge asteroid in a bid to protect Earth from an impact, but the target space rock poses virtually no threat to our planet and moving it could actually make matters worse, experts say.

Next year will be crucial for global nuclear non-proliferation efforts and all eyes will be on the United States and Russia to see if the two top atomic powers can reach a deal to reduce their arsenals.

The United States has begun talks with Russia and a United Nations arms control committee about strengthening Internet security and limiting military use of cyberspace. Officials familiar with the talks said the Obama administration realized that more nations were developing cyberweapons and that a new approach was needed to blunt an international arms race.

An in-depth history of the "Soviet Star Wars" program, that in 1987 attempted to launch an orbiting battlestation with an anti-satellite, sky-sweeping laser weapon, and a space-to-earth kinetic warhead system, but failed during launch due to a small programming error.

Russia should build a new nuclear-powered spaceship for prospective manned missions to Mars and other planets, the nation's space chief said Thursday.

With a key arms control treaty (the Strategic Arms Reduction Treaty or START) set to expire soon, the Obama administration is searching for ways to keep inspectors in Russia or else it risks losing American eyes on the world’s second most formidable nuclear weapons arsenal for the first time in decades.

The United States will be able to hit any target in Russia from space by 2030, the commander of Russia's air force said on Tuesday, announcing that Moscow will develop a new air defense system to avert the threat.
