Future of US space travel uncertain

عنوان درس: آینده سفر فضایی آمریکا نامعلوم است تیمی از کارشناسان فضایی مستقل کاخ سفید آمریکا، در مورد برنامه ناسا برای رفتن مجدد به کره ماه یا فرستادن فضانوردان به کره مریخ ابراز تردید جدی کرده اند. این تیم می گوید بودجه سالانه کنونی که 18 میلیارد دلار است برای تامین هزینه این برنامه های فضایی، بهیچوجه کافی نیست. Five years ago President Bush set out his lofty vision of sending astronauts back to the Moon by the year 2020. It was meant to be the staging post for the next frontier - a manned landing on Mars. Now a panel of space experts says that's pretty much pie in the sky. Their report, commissioned by President Obama, says the current US human spaceflight programme appears to be on an unsustainable trajectory. It suggests the only way forward is to increase the funding of NASA by billions of dollars, or to co-operate with private companies now embarking on commercial space flights. The panel says visits to Near-Earth Objects such as asteroids are far more realistic too. The experts also argue for keeping the International Space Station going till 2020, rather than pulling the plug in six years' time.
