A | LONDON -- LONDON (AP) — Greta Thunberg was detained by British police on Tuesday alongside other climate activists who gathered outside a central London hotel to disrupt a major oil and gas industry conference.Thunberg was among dozens of protesters who chanted “oily money out” and sought to block access to the luxury InterContinental Hotel on Park Lane, which is hosting the Energy Intelligence Forum. The conference features speakers including the chief executives of Shell, Saudi Arabia’s Aramco and Norway’s Equinor, as well as the U.K.’s energy security minister. An Associated Press photographer saw officers speaking with Thunberg before leading her away and taking her into a police vehicle.Protesters attempted to block access to the conference venue by sitting on the sidewalk by the entrance. They held aloft banners and chanted “oily money out” and “cancel the conference,” while some lit yellow and pink smoke flares.Two Greenpeace activists abseiled down from the roof of the hotel to unfurl a giant banner reading “Make Big Oil Pay.” London's Metropolitan Police said that six people were initially arrested on suspicion of obstructing a highway during the protest. The force said a further 14 were detained on suspicion of disrupting public order, and one other person was detained for criminal damage.Police said they engaged in conversations with the protesters on allowing people to access the venue safely and prevent serious disruption to the hotel and guests, but some of the activists refused to move from the road.No charges have been issued yet.’We were linking arms when the police forced their way in and singled out Greta. She was dragged down the street at speed to a police van where they refused to say where she was being taken," said Joanna Warrington, an organizer with Fossil Free London who was at the demonstration.The protesters accuse fossil fuel companies of deliberately slowing the global energy transition to renewables in order to make more profit.“The world is drowning in fossil fuels. Our hopes and dreams and lives are being washed away by a flood of greenwashing and lies,” Thunberg told reporters before she was detained. “It has been clear for decades that the fossil fuel industries were well aware of the consequences of their business models, and yet they have done nothing.”“We cannot let this continue. The elite of the oil and money conference, they have no intention of transition,” she added. “We have no other option but to put our bodies outside this conference and to physically disrupt. And we have to do that every time, we have to continue showing them that they are not going to get away with this.”Police said those detained were taken into custody and that officers remained on site. Environmental groups say they will continue to protest throughout the planned forum, which is expected to last three days. Thunberg inspired a global youth movement demanding stronger efforts to fight climate change after staging weekly protests outside the Swedish Parliament starting in 2018. She was recently fined by a Swedish court for disobeying police during an environmental protest in Sweden.。

B | 北京时间,2019年1月16日,可能是美国宇航员再次从美国大陆乘宇宙飞船进入太空轨道的一年,结束了自2011年美国国家航空航天局退役以来的8年空白期。美国国家航空航天局的首次商业载人飞行预计将在未来几个月进行,这标志着美国国家航空航天局的宇航员将首次由私人航天公司的航天器运载。如果目前的计划顺利进行,SpaceX将成为第一家私人航天公司,发射载人航天器,将两名美国宇航局宇航员送入太空。最近,科技博客Verge访问了位于加利福尼亚州霍桑的SpaceX总部,并与美国宇航局宇航员联系,了解美国载人航天飞行的未来。SpaceX及其竞争对手波音公司与美国宇航局签订了一份合同,为美国宇航局开发一种新的航天器,用于在近地轨道上来回运送宇航员。

C | 波音公司从零开始开发了一种新的载人航天器CST-100星际客机。SpaceX的载人飞船是在现有的“龙”货运飞船的基础上进行的一次升级,该飞船已被用于向国际空间站运送补给。在过去的五年里,SpaceX一直在改进其“龙货运”航天器,使其能够运送更为遥远和珍贵的宇航员货物。

D | 美国宇航局商业载人飞行计划的最终目标是拥有两个新的美国航天器,定期将美国宇航局宇航员往返于国际空间站。

E | 自2011年美国宇航局取消航天飞机计划以来,美国宇航局一直依赖俄罗斯将其宇航员和国际合作伙伴送到国际空间站。

F | 美国国家航空航天局依靠私营航天公司,不仅可以满足其需求,而且有助于促进商业航天工业的发展。航天X和波音公司也承担了一些航天器开发的成本,这可能比美国宇航局自己的航天器开发节省很多资金。去年8月,美国国家航空航天局宣布,首批9名美国宇航员驾驶航天X和波音飞船。如果计划的发射日期不变,执行美国宇航局商业载人飞行计划的前两名宇航员将是鲍勃·本肯和道格·赫尔利。这两名经验丰富的美国宇航局宇航员将被送往国际空间站,执行“太空x号”载人飞船的首次任务。

G | 作为检查宇宙飞船是否准备好载人飞行的试飞的一部分,他们目前的目标是在两周内乘坐载人“龙”号宇宙飞船前往国际空间站。

H | 宇宙飞船将被放置在太空猎鹰9号火箭的顶部,将它们送入轨道,与国际空间站对接,然后分离返回地球,溅落在海面上。班肯和海利以前都曾在美国宇航局的航天飞机任务,但现在正在接受适应新航天器的训练。由于有人驾驶的“龙”号宇宙飞船最终是“太空X”号宇宙飞船,因此“太空X”还负责培训宇航员如何使用宇宙飞船。虽然这是一个新的过程,宇航员们说他们的训练计划没有改变太多。”“无论是飞机还是汽车,汽车培训都是相似的,”班肯说。

I | 显然,开车比宇宙飞船容易。但我的意思是,你需要学习新的系统,如何处理宇宙飞船,然后在发生故障时怎么做,以及如何在宇宙飞船中生活。航天器模拟器SpaceX在其总部建造了一个航天器模拟器,模拟宇航员在太空旅行中可能遇到的情况。这些机器复制了航天器的内部,包括椅子、舱口和用于监控飞行状况的触摸屏。它与航天飞机的设计大不相同,航天飞机的驾驶舱里有数千个开关和断路器。最终,在载人飞船的正常飞行过程中,它将尽可能减少宇航员需要执行的输入操作,但仍要求宇航员在必要时进行干预。训练过程的很大一部分涉及宇航员对可能出现的问题的每一分钟细节进行审查,以便宇航员知道在必要时如何干预和解决问题。航天指挥部每隔一周就要为“龙”号宇宙飞船模拟器配备一次,班肯和海利将从家里前往航天指挥部进行训练,训练将一直持续到任务结束。载人任务代号为DM-2,暂定于2019年6月完成。但在此之前,SpaceX必须首先执行载人航天器的无人试验任务DM-1。试飞日期推迟了。美国航天局首先将日期定在1月7日,然后推迟到1月17日。最近,美国宇航局将飞行试验日期推迟到了2月。

J | 许多人认为,最近的拖延与美国政府的关闭有关。

K | 然而,知情人士表示,由于商业载人飞行计划对美国宇航局至关重要,美国宇航局目前的人员配备水平相对正常。美国航天局发言人鲍勃·雅各布斯证实,延长试飞至2月与政府关闭无关。考虑到试飞日期的不确定性,班肯和海利说,他们的生活规划必须灵活,类似于航天飞机时代。

L | 但他们说,他们每两周就知道一次时间表,自从他们第一次被选为商业载人任务的宇航员以来,情况就是这样。”班肯说:“我们几乎一直在计划很多事情,只是在一个特殊的星期里做我们需要做的。”无论是家庭度假还是火箭发射,我们都可能同时安排了。当时我们只是在做高优先级的事情。

M | 一般来说,火箭发射是首要任务。

N | 最重要的是,美国航天局希望在执行任务前确保航天器准备就绪并处于最安全的状态。一旦载人飞船的第一次无人试飞完成,美国宇航局将评估该任务的成功率,然后决定是否批准载人试飞。这意味着班肯和海利的任务能否执行,以及他们能否成为第一个商业载人宇航员仍是一个大问题。

o | 波音太空船将搭载三名乘客。如果波音在载人航天飞机上的进展超过了航天X,那么这艘宇宙飞船的第一批乘客将是三名:美国宇航局宇航员埃里克•博、妮可•奥纳普•曼和前宇航员兼波音员工克里斯•弗格森。

p | 但对于前两名宇宙飞船的宇航员来说,他们能否成为第一名并不是最重要的。

q | 和过去一样,他们将乘坐宇宙飞船从佛罗里达起飞。”班肯说:“如果你还有机会去国际空间站,你可以乘坐任何航天器。
