January 28th, 1986, before a television audience, seven passengers aboard the Space Shuttle Challenger took flight from the Kennedy Space Center in Florida. 1986年1月28日，在电视观众面前，挑战者号航天飞机上的七名乘客从佛罗里达州的肯尼迪航天中心起飞。
Among them was Christa McAuliffe, who was selected in a nationwide search for a teacher to be NASA's first citizen passenger in space. 其中一位是克里斯塔·麦考利芙，她是在全国范围内选拔出来的教师，将成为NASA首位进入太空的普通公民乘客。
I don't think any teacher has ever been more ready to have two lessons in my life. 我认为在我的教学生涯中，从来没有哪位老师像我这样准备好上两节课。
I've been preparing these in September, and I just hope everybody tunes in on day 4 now to watch the teacher teaching from space. 我一直在九月份准备这些内容，现在只希望大家都能在第四天收看老师从太空授课。
Just 73 seconds after takeoff disaster after a rubber seal in one of the shuttle's twin booster rockets failed, triggering an explosion that doomed all on board. 起飞后仅73秒，灾难降临——航天飞机的两枚助推火箭之一的橡胶密封圈失效，引发爆炸，致使机上所有人员全部遇难。
Then president Ronald Reagan eulogized the crew and called them heroes. 随后，罗纳德·里根总统悼念了机组人员，并称他们为英雄。
And while the flight exposed failures in NASA management who ignored safety warnings from scientists, it's widely regarded as planting the seed for shuttle development in today's commercial space flights. 尽管这次飞行暴露了NASA管理层忽视科学家安全警告的失误，但人们普遍认为，它为当今商业太空飞行中的航天飞机发展播下了种子。
Companies like SpaceX have even flown missions to the International Space Station, where on Wednesday astronauts Michael Hopkins and Victor Glover spacewalk to finish installing a European science platform and complete long-term battery upgrades. 像SpaceX这样的公司甚至已经执行了前往国际空间站的任务，周三，宇航员迈克尔·霍普金斯和维克多·格洛弗在那里进行太空行走，以完成欧洲科学平台的安装，并完成长期电池升级任务。
The advancements can further research on Earth observation, robotics, material science and astrophysics. This according to a tweet from the space station's twitter account. 这些进展可进一步推动地球观测、机器人技术、材料科学和天体物理学领域的研究。这一消息来自空间站推特账号发布的一条推文。
Back on Earth, climatologists sounded yet another alarm this week. An estimated 28 trillion metric tons of ice have melted from icesheetsand glaciers since the mid 1990s. 回到地球，气候学家本周再次发出警报。自20世纪90年代中期以来，冰盖和冰川估计已有28万亿公吨的冰融化。
That's 57 percent faster than it was three decades ago, per report scientists published Monday in the journal The Cryosphere. 根据科学家们周一在The Cryosphere期刊上发表的报告，这比三十年前快了57%。
In that time, global sea levels have risen three and a half centimeters, while the global temperature has gone up by one degree Celsius. 在此期间，全球海平面上升了3.5厘米， 而全球气温上升了一摄氏度。
Finally this week, abutcherin Scotland sent a bag of haggis into the atmosphere. 苏格兰的一位屠夫将一袋哈吉斯送入了大气层。
Simon Howie's bag of organ meats climbed more than 32 kilometers before falling back to the ground. 西蒙·豪伊的那袋动物内脏上升了超过32公里，然后才落回地面。
He claims it was the first haggis to reach such heights and says he hopes it inspires children's interest in space. 他声称这是第一份到达如此高度的哈吉斯，并表示他希望这能激发孩子们对太空的兴趣。

When news spread late last year that the Fermilab National AcceleratorLaboratoryin suburban Chicago was part of a project achieving quantum teleportation, it conjured up scenes from the classic science fiction franchise Star Trek in which the show's characters could beam from one location to another. 去年年底，当有消息传出芝加哥郊外的费米国家加速器实验室参与了一个实现量子隐形传态的项目时，这不禁让人联想到经典科幻系列《星际迷航》中的场景——剧中角色可以从一个地点瞬间传送到另一个地点。
What if you could control your car, turn on your oven, or sign your name by touching an invisible screen? 要是你能通过触摸一块看不见的屏幕操控汽车、打开烤箱、或是签名，会怎么样？
Scientists say the developing El Niño is already the strongest ever recorded, with sea temperatures in a key region of the Pacific more than three degrees above average, and this event is not expected to peak until later this year. 科学家表示，目前正在形成的厄尔尼诺现象已达到有记录以来最强水平，太平洋一个关键海域的海水温度比平均水平高出三度以上，而此次厄尔尼诺预计要到今年晚些时候才会达到峰值。
The Sun has set, and you're headed to a train station in Stockholm with your overnight bag. You board the sleeper train, change into your comfortable clothes, enjoy the scenery through the window for a while before laying your head down to rest. Snoring from the other passengers in your shared cabin delays your bedtime, but the gentle motion and white noise eventually send you to sleep. The next morning, just over 12 hours later, you wake up in Germany's second largest city, Hamburg. "It still sounds like a long time, but you go to sleep, and it's such a nice atmosphere on the train," says Julia Senninger, a fan of sleeper trains. 太阳已经落山，您带着过夜行李前往斯德哥尔摩的火车站。 登上卧铺列车，换上舒适的衣服，欣赏一下窗外的风景，然后就低头休息。 共用客舱内其他乘客的鼾声会延迟您的就寝时间，但轻柔的动作和白噪音最终会让您入睡。 第二天早上，12 个多小时后，您在德国第二大城市汉堡醒来。 “听起来还是很长一段时间，但你很快就睡着了，火车上的气氛真好，”卧铺火车的粉丝朱莉娅·森宁格 (Julia Senninger) 说道。
Protesters continue to gather outside the U.S. Agency for International Development on Monday after Elon Musk and President Trump made moves to dismantle the agency charged with delivering humanitarian assistance overseas. 周一，在埃隆·马斯克和特朗普总统采取行动解散负责向海外提供人道主义援助的美国国际开发署后，抗议者继续聚集在美国国际开发署外。
