I was reading in the news that NASA was testing sending humans beyond the earth's orbit (higher than 200 miles I think ), so the test was this program and they were happy because it succeeded to send an unmanned vehicle to 3200 miles, so I started wondering, if they had already sent a human to the moon why they were re-inventing the wheel? How could they send a human to 250000 km if they are happy to make him reach 5000 km?
Any thought?
