有时候我们都可以从朋友那里得到一点帮助。美国宇航局的尼尔·格瑞斯·斯威夫特天文台在服役近22年之后，需要一个推力来保持在轨道上。这段视频展示了艺术家对斯威夫特推进任务的可视化：7月3日，催化剂的LINK航天器由诺斯罗普·格鲁曼公司的飞马座XL火箭发射升空，现在它正在与斯威夫特会合的途中，并在接下来的几个月里将其推进到更高的轨道。这种策略以前从未有人尝试过。如果成功，它将是一种新的关键能力的技术演示，以延长低地球轨道航天器的寿命，其轨道会随着时间的推移而衰减。斯威夫特拥有一系列仪器，可以观测宇宙中伽马射线、x射线和紫外线中能量最大的爆炸，并且具有在几十秒内重新指向爆炸方向的独特能力。世界各地的天文学家，以及所有宇宙爆炸的粉丝，都在焦急地期待着这次任务的成功！

Sometimes we can all use a little help from a friend. NASA's Neil Gehrels Swift Observatory needs a boost to stay in orbit after almost 22 years of service. This video shows an artist's visualization of the Swift Boost Mission: The Katalyst's LINK spacecraft was launched aboard a Northrop Grumman Pegasus XL rocket on July 3 and it is now en route to rendezvous with Swift and boost it to a higher orbit over the course of the next several months. This type of maneuver has never been attempted before. If successful, it will be the technology demonstration of a new key capability to extended the lifetime of spacecraft in low Earth orbit, whose orbits decay over time. Swift has an array of instruments that observe the most energetic explosions in the Universe in gamma-rays, X-rays and ultraviolet, and the unique ability to repoint in their direction within tens of seconds. Astronomers around the world, and indeed all fans of cosmic explosions, are anxiously hoping for a successful mission!
