A private company based in Colorado in the United States, and backed by former NASA engineers, has said it intends to fly a manned space mission by the year 2020. The company said it could send lunar missions at a fraction of the cost of government-run operations. It intends to send two people to the Moon for 1.4 billion dollars. Golden Spike Company said it will use existing rocket and capsule technology, and will aim for a first launch before the end of the decade.
