PARIS: Europe will commission two rocket launches from Elon Musk<\/a>'s SpaceX<\/a> after the Ukraine conflict barred access to Russia's Soyuz, the European Space Agency<\/a> (ESA) confirmed on Thursday.
The launches include the Euclid space telescope and the Hera<\/a> probe, a follow-up mission to NASA<\/a>'s DART spacecraft<\/a> which last month succeeded in altering the path of a moonlet in the first test of a future planetary defence system.
\"The member states have decided that Euclid and Hera are proposed to be launched on Falcon 9,\" ESA Director General Josef Aschbacher told reporters after a meeting of the 22-nation agency's ministerial council.
The launches will take place in 2023 and 2024 respectively.
Reuters reported in August that ESA had begun preliminary technical discussions with SpaceX that could lead to the temporary use of its launchers after the Ukraine conflict blocked Western access to Russia's Soyuz rockets.
Industry sources had said up to two launches could be affected by the switch from Soyuz to SpaceX.
A third payload which had been due to ride on Soyuz - the Earth Cloud Aerosol and Radiation Explorer<\/a>, or EarthCARE<\/a> - will now be launched on Europe's Vega C<\/a> instead, Aschbacher said.
Built by Airbus on behalf of the European and Japanese space agencies, the EarthCARE satellite will be launched in early 2024 to fill a gap in the scientific modelling of climate change.
ESA is still looking for alternatives for two further missions that had been in the Soyuz launch pipeline.
Aschbacher made the announcement a day after ESA revealed a new fourth-quarter 2023 target for the first launch of Ariane 6, its latest launch vehicle, marking a delay of about six months.
ESA had previously said Ariane 6 could slip into 2023 from 2022 without giving a more precise window, but it was widely understood to be aiming for early next year.
Originally due to make its first launch in 2020, the twin-variant Ariane 6 was developed to counter lower-cost competition from SpaceX and preserve Europe's independent access to space.
Europe has until now depended on the Italian Vega for small payloads, Russia's Soyuz for medium ones and the near-retirement Ariane 5 for heavy missions.
ESA said on Wednesday it planned to launch the three remaining Ariane 5 rockets in the first half of next year.

SpaceX公司雇佣了两个欧洲俄罗斯留下发射来填补缺口
推出包括欧几里得空间望远镜和赫拉探针,后续任务,美国航空航天局的飞镖飞船上月成功地改变了路径的人造卫星在第一个测试中未来的行星防御系统。

巴黎:欧洲委员会两个火箭发射Elon Musk的SpaceX公司乌克兰冲突后禁止访问的俄罗斯“联盟号”飞船,欧洲太空总署(ESA)周四确认。
推出包括欧几里得空间望远镜和赫拉调查,后续任务美国国家航空航天局的飞镖宇宙飞船上月成功地改变了路径的人造卫星在第一个测试中未来的行星防御系统。
“成员国决定,欧几里得和赫拉在猎鹰9号发射,“欧洲航天局局长约瑟夫Aschbacher民意机构举行的会议后告诉记者的部长级理事会。
发射将分别于2023年和2024年。
据路透社报道,8月欧洲航天局已经开始初步技术与SpaceX的讨论可能导致乌克兰冲突后的临时使用发射器阻止西方访问俄罗斯的“联盟”号火箭。
业内人士曾表示两个发射可以从联盟号切换到SpaceX的影响。
第三个载荷曾因乘坐“联盟”号——地球气溶胶和云辐射探测器,或EarthCARE——现在将推出了欧洲织女星C相反,Aschbacher说。
由空客代表欧洲和日本空间机构,EarthCARE卫星将于2024年初在气候变化的科学造型填补空缺。
ESA仍在寻找替代两个进一步的任务已经在联盟号启动管道。
Aschbacher宣布的前一天,ESA显示一个新的2023年第四季度目标阿丽亚娜6的第一次发射,其最新的运载火箭,推迟6个月左右。
ESA曾表示阿丽亚娜6可能会从2022年到2023年没有给出一个更精确的窗口,但它被广泛理解为明年年初的目标。
最初将使其在2020年首次推出,twin-variant阿丽亚娜6开发应对低成本竞争SpaceX和保护欧洲的独立进入太空。
欧洲直到现在依赖于意大利维加小载荷,俄罗斯的联盟号中等的和接近退役阿丽亚娜5重的任务。
欧洲航天局周三表示,计划推出剩下的三阿丽亚娜5火箭明年上半年。
