今年1月6日,欧洲航天局的新型运载火箭“阿丽亚娜”5,成功地通过了最后一次测试。但是它的发射一再推迟,最后在6月4日发射时失败,火箭升空后偏离了预定轨道,由地面控制中心引爆。“阿丽亚娜”-5火箭是法国宇航公司等1985年开始为欧洲航天局研制的,当时主要是为了发射欧洲载人航天飞机“赫尔墨斯”,因而对可靠性提出了很高的 On January 6 this year, the new launch vehicle “Ariane” of the European Space Agency 5 successfully passed its last test. However, its launch was postponed repeatedly and finally failed on launch on 4 June. As the rocket departed from its planned orbit after being launched, the rocket detonated by the ground control center. The “Ariane -5” rocket was first developed by NASA for the European Space Agency in 1985 when France Aerospace was mainly responsible for the launch of the European manned space shuttle Hermes and thus posed a high degree of reliability
