1971年2月4日,阿波罗14号到达月球轨道

Apollo 14 arrived in lunar orbit on Feb. 4, 1971, to prepare for the landing in and exploration of the Fra Mauro highlands. Apollo 14 launched carrying astronauts Commander Alan Shepard, lunar module pilot Edgar Mitchell, and command module pilot Stuart Roosa. Engineers had modified the spacecraft to prevent a recurrence of the accident that crippled Apollo 13 the previous year. After their Saturn V rocket delivered them into a parking orbit around the Earth, the third stage reignited to send them on their way to the Moon. The primary mission objectives to the Fra Mauro region of the Moon centered on deployment of the Apollo Lunar Surface Experiments Package, lunar field geology investigations; collection of surface material samples for return to Earth; and deployment…

从空间站看月球

This picture of the waning gibbous Moon was taken on Jan 29, 2021, the day after its full Moon phase as the International Space Station orbited 264 miles above China near the Mongolian border. Humanity’s only orbital laboratory, the space station, orbits the Earth about 90 minutes or about 16 times every 24 hours. Image Credit: NASA 这张照片拍摄于2021年1月29日,也就是满月后的第二天,当时国际空间站在靠近蒙古边境的中国上空264英里的轨道上运行。空间站是人类唯一的轨道实验室,它绕地球轨道运行约90分钟,即每24小时运行16次。 图片来源:美国国家航空航天局

铭记STS-107和它的机组人员

The STS-107 crewmembers strike a ‘flying’ pose for their traditional in-flight crew portrait in the SPACEHAB Research Double Module aboard the space shuttle Columbia. From the left (top row), wearing blue shirts, are astronauts David M. Brown, mission specialist; William C. McCool, pilot; and Michael P. Anderson, payload commander. From the left (bottom row), wearing red shirts to signify their shift’s color, are astronauts Kalpana Chawla, mission specialist; Rick D. Husband, mission commander; Laurel B. Clark, mission specialist; and Ilan Ramon, payload specialist, representing the Israeli Space Agency. On Feb. 1, 2003, the seven crewmembers were lost with the Space Shuttle Columbia over North Texas. This picture was on a roll of unprocessed film later recovered by searchers from the debris.

哈勃望远镜发现了星际间的相互作用

哈勃望远镜发现了星际间的相互作用

The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion). The oblate shells of ESO 455-10, previously held tightly together as layers of its central star, not only give this planetary nebula its unique appearance, but also offer information about the nebula. Seen in a field of stars, the distinct asymmetrical arc of material over the north side of the nebula is a clear sign of interactions between ESO 455-10 and the interstellar medium. The interstellar medium is the material such as diffuse gas between star…

At NASA’s Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion’s crew module for the Artemis III mission that will land the first woman and next man on the Moon. The crew module’s primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded together through a weld process that produces a strong, air-tight habitable space for astronauts during the mission. The pressure vessel is designed to withstand the harsh and demanding environment of deep space, and is the core structure upon which all the other elements of Orion’s crew module are integrated. With welding complete on the crew module cone panels – one of which contains windows…

Kepler-22b is the first planet discovered inside the habitable zone of a Sun-like star. This artist’s conception from 2011, shows the first planet that NASA’s Kepler mission has confirmed to orbit the region around a star where liquid water, a requirement for life on Earth, could exist. This exoplanet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our Sun. At the time scientists did not know if the planet has a predominantly rocky, gaseous or liquid composition. It’s possible that the world would have clouds in its atmosphere, as depicted here in the artist’s interpretation.

A powerful new antenna has been added to the NASA Space Communications and Navigation’s Deep Space Network (DSN), which connects us to the space robots exploring our solar system. Called Deep Space Station 56, or DSS-56, the dish is now online and ready to communicate with a variety of missions, including NASA’s Perseverance rover when it lands on the Red Planet next month. The new 34-meter-wide (112-foot-wide) dish has been under construction at the Madrid Deep Space Communications Complex in Spain since 2017. Existing antennas are limited in the frequency bands they can receive and transmit, often restricting them to communicating only with specific spacecraft. DSS-56 is the first to use the Deep Space Network’s full range of communication frequencies as soon as it went…

哈勃太空望远镜拍摄“迷失星系”的照片

Located in the constellation of Virgo (The Virgin), around 50 million light-years from Earth, the galaxy NGC 4535 is truly a stunning sight to behold. Despite the incredible quality of this image, taken from the NASA/ESA Hubble Space Telescope, NGC 4535 has a hazy, somewhat ghostly, appearance when viewed from a smaller telescope. This led amateur astronomer Leland S. Copeland to nickname NGC 4535 the “Lost Galaxy” in the 1950s. The bright colors in this image aren’t just beautiful to look at, as they actually tell us about the population of stars within this barred spiral galaxy. The bright blue-ish colors, seen nestled amongst NGC 4535’s long, spiral arms, indicate the presence of a greater number of younger and hotter stars. In contrast, the yellower…
