这里有或激扬或深情的诗篇，这里有或浩渺或咫尺的星辰，这里也有一个个人类智慧的结晶和一颗颗不知安放何处的灵魂。来这里，与星月同饮，伴四海巡游，共时空一梦！
Today is the first anniversary of Hawking’s death.
A year ago today, Hawking had to leave us forever, a great scientific craftsman sleeps forever.
Hawking left, but his mind was immortalized. It was he who took us hundreds of millions of light-years away to appreciate the mystery there, he made us realize the eternity of time and the vastness of space, he taught us that humans are born small, but can achieve greatness.
Salute to the greatness and Hawking!
今天是中秋节，一个关于团圆和月亮的节日。
李白曾“举杯邀明月”，自认为可以“对影成三人”，我们可以将此理解为诗人的诗意。然而，自古至今，月球对于人类的吸引力从未削减——晴朗的夜空，一轮明月高悬空中，宛若晶莹的碧玉，偶尔飘过的几朵隐隐约约的云彩，向只能待在地球上的人类炫耀着天宫的美轮美奂。

Regardless of the amount of winter ice cover, the waters off of the Alaskan coast usually come alive each spring with blooms of phytoplankton. These blooms can form striking patterns of blue and green seawater, such as those visible in this image of the Chukchi Sea acquired on June 18, 2018, by the Operational Land Imager (OLI) on Landsat 8.
不考虑冬季冰盖的数量，基本上每年的春天，阿拉斯加海岸附近的水域都会随着浮游植物的盛放而显得生机勃勃．这些盛放的浮游植物可以形成引人注目的蓝色或者绿色的海水，例如这张由地球资源卫星8号上的军用陆地成像仪于2018年6月18日在 Chukchi 海拍摄到的图像．

Launched nearly 15 years ago on August 25, 2003, the Spitzer Space Telescope is the final mission in NASA’s Great Observatories Program – a family of four space-based observatories, each observing the universe in a different kind of light. The other missions in the program include the visible-light Hubble Space Telescope, Compton Gamma-Ray Observatory, and the Chandra X-Ray Observatory.
Spitzer太空望远镜于大约15年前的2003年08月25日发射升空，这是NASA伟大天文台计划的最后一个任务，这个任务的大家庭包含4个太空望远镜，每个观测站以不同的波段观测着宇宙。该计划中的其他成员包括：工作在可见光波段的哈勃太空望远镜，Compton伽玛射线天文台以及Chandra X 射线天文台。
SpaceX的龙飞船正在NASA位于俄亥俄州的Plum Brook站点接受关于太空推进设备的测试。这是世界上唯一一个能够在模拟的高空环境中测试全尺寸高级运载工具和火箭发动机的地方。这个实验仓将允许SpaceX和NASA验证龙飞船是否有能力经受太空的真空环境和极端的温度。
If you have ever seen a series of concentric rings of color near a mist or fog, you have likely seen a glory. This colorful optical phenomenon, bright red on the outside and blue toward the center, forms when water droplets scatter sunlight back toward a source of light.
This new composite image shows the region around the Pillars, which are about 5,700 light years from Earth. The image combines X-ray data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope optical data. The optical image, taken with filters to emphasize the interstellar gas and dust, shows dusty brown nebula immersed in a blue-green haze, and a few stars that appear as pink dots in the image. The Chandra data reveal X-rays from hot outer atmospheres from stars. In this image, low, medium, and high-energy X-rays detected by Chandra have been colored red, green, and blue.
As the International Space Station flew overhead, NASA astronaut Ricky Arnold captured this photograph of a changing landscape in the heart of Madagascar, observing drainage into the sea in the Betsiboka Estuary due to decimation of rainforests and coastal mangroves.
2018年06月08日，由于遭遇火星全球范围的大规模灰尘风暴，依靠太阳能获取能源的＂机遇号＂火星车被迫停止了科学活动，随后进入了休眠状态．据NASA的预测，这次火星灰尘风暴将可能持续数周到数月的时间，＂机遇号＂火星车能否在没有足够的电力对电池进行保温的情况下度过火星上寒冷的漫漫长夜并苏醒过来，还是一个未知数．
NASA has selected six women and men to join the elite corps of flight directors who will lead mission control for a variety of new operations at the agency’s Johnson Space Center in Houston. From left to right: Marcos Flores, Allison Bolinger, Adi Boulos, Rebecca Wingfield, Pooja Jesrani, and Paul Konyha.
The Earth’s limb and the Pacific Ocean contrast segments of the International Space Station’s Kibo laboratory module built by the Japan Aerospace Exploration Agency in this June 23, 2018 image. At right is a portion of the Experiment Logistics Module, Pressurized Section (ELM-PS) which is the Kibo lab’s storage facility. Next to the ELM-PS is Kibo’s 10-meter-long robotic arm, or Remote Manipulator System, which is attached to the lab module’s core component, the Pressurized Module.
NASA’s Ikhana aircraft, based at the agency’s Armstrong Flight Research Center in Edwards, California, takes off on June 12, 2018, for the agency’s first large-scale, remotely-piloted aircraft flight in the national airspace without a safety chase aircraft. The successful flight moved the United States one step closer to normalizing unmanned aircraft operations in the airspace used by commercial and private pilots.
Posted to Twitter by @Astro_Alex, European Space Agency astronaut Alexander Gerst, this image shows our planet’s Moon as seen from the International Space Station. As he said in the tweet, “By orbiting the Earth almost 16 times per day, the #ISS crew travel the distance to the Moon and back – every day. #Horizons”
This image of Jupiter’s southern hemisphere was captured by NASA’s Juno spacecraft on the outbound leg of a close flyby of the gas-giant planet. Citizen scientist Kevin M. Gill created this image using data from the spacecraft’s JunoCam imager.
