60.234.130.39 (talk) 22:58, 10 August 2008 (UTC)in july 1965, Marina, 4 sent back the first close up pictures of mars.By 0971 further missions had managed to map the whole of the planets surface. In 1989, Us president Bush set a target of landing on mars by the year 2019.Scientist still have a long way to go before the three-year round trip can be undertaken. For example in 1999 a mars probe was lost when the multi national developers failed to allow freo the difference between metric and imperial measurements.
