The agency provided specialized ground support on Jan. 11 for Samaritan’s Purse, enabling the aid organization to land their DC-8 cargo jet at NASA’s Armstrong Flight Research Center Building 703 in Palmdale, California. The Samaritan’s Purse DC-8 arrived early Monday with supplies to aid in Los Angeles County’s Emergency Field Hospital that will expand capacity to care for COVID-19 patients at Antelope Valley Hospital. The aircraft is specially configured to carry up to 84,000 pounds of cargo and 32 passengers in support of…

The core stage for the first flight of NASA’s Space Launch System, or SLS, rocket is seen in the B-2 Test Stand during a scheduled 8-minute duration hot fire test, Saturday, Jan. 16, 2021, at Stennis Space Center near Bay St. Louis, Mississippi. The four RS-25 engines fired for a little more than one minute and generated 1.6 million pounds of thrust. The hot fire is the final test of the Green Run test series, a comprehensive assessment of the Space Launch System’s core stage prior to launching the Artemis I mission to the Moon. Learn more about Green Run and the data captured from this test.

President Lyndon B. Johnson signs the Civil Rights Act on July 2, 1964, as Rev. Dr. Martin Luther King Jr. and others, look on. NASA continues to fulfill the dream of diversity and inclusion in all its activities – from spaceflight to technology. As Administrator Jim Bridenstine said in a letter to employees on Jan. 11, 2021: “I believe that the example we set at this agency through the display of our core values – safety, integrity, teamwork, excellence, and inclusion – can help carry us through these troubling times. There is no agency in the federal government better equipped than NASA to inspire the American people to reach greater heights and remind our fellow citizens that when we are united, there is no challenge…

明亮的蓝色恒星

明亮的蓝色恒星

ByNASA中文

Inside star cluster NGC 602, a star-forming region in the Small Magellanic Cloud, bright, blue, newly formed stars are blowing a cavity in this nebula,sculpting the inner edge of its outer portions, slowly eroding it away and eating into the material beyond. The diffuse outer reaches of the nebula prevent the energetic outflows from streaming away from the cluster. Elephant trunk–like dust pillars point toward the hot blue stars and are telltale signs of their eroding effect. Star formation started at the center of the cluster and propagated outward, with the youngest stars still forming today along the dust ridges. Image Credit: NASA 在星团NGC 602内部，小麦哲伦星云中的恒星形成区域，明亮、蓝色、新形成的恒星正在星云中吹出一个空腔，雕刻着其外部部分的内缘，慢慢地将其腐蚀掉，并侵蚀着外面的物质。星云扩散的外层区域阻止了从星团中流出的能量。象鼻状的尘埃柱指向炽热的蓝色恒星，这是它们受到侵蚀的迹象。恒星的形成始于星团的中心，并向外传播，最年轻的恒星至今仍在沿着星尘脊形成。 影像来源：NASA

寻找失踪的黑洞

寻找失踪的黑洞

ByNASA中文

Despite searching with NASA’s Chandra X-ray Observatory and Hubble Space Telescope, astronomers have no evidence that a distant black hole estimated to weigh between 3 billion and 100 billion times the mass of the Sun is anywhere to be found. This missing black hole should be in the enormous galaxy in the center of the galaxy cluster Abell 2261, which is located about 2.7 billion light years from Earth. This composite image of Abell 2261 contains optical data from Hubble and the Subaru Telescope showing galaxies in the cluster and in the background, and Chandra X-ray data showing hot gas (colored pink) pervading the cluster. The middle of the image shows the large elliptical galaxy in the center of the cluster. Learn more. Image Credit:…

The HUNCH – High school students United with NASA to Create Hardware – Program has expanded its partnership opportunities to the Dade County, Georgia, school system in Trenton. Students will increase their advanced manufacturing capabilities by producing super-strength carbon fiber elements for NASA, the International Space Station, and future deep space products. HUNCH was designed to inspire students through project-based learning. Students have opportunities to participate in six HUNCH focus areas — design and prototyping, software, hardware, sewn flight articles, video and media, and culinary arts. Schools can participate in HUNCH by meeting a set of minimal qualifications and having the capability to complete program requirements. To be a successful program, HUNCH organizers recommend that school faculties include teachers with prior experience in the focus…

Northrop Grumman’s Cygnus space freighter departs the International Space Station moments after being released from the Canadarm2 robotic arm on Thursday, Jan. 7, 2021, completing a 93-day cargo mission attached to the orbiting lab. The Cygnus spacecraft successfully departed the International Space Station three months after arriving at the space station to deliver about 8,000 pounds of scientific experiments and supplies to the orbiting laboratory. Prior to departure, the crew packed Cygnus with the Saffire V investigation and the SharkSat hosted payload to be conducted during an extended mission in orbit. On Jan. 26, Northrop Grumman flight controllers in Dulles, Virginia, will initiate Cygnus’ deorbit to perform a safe re-entry, burning up in Earth’s atmosphere.

研究特洛伊小行星的露西任务

ByNASA中文

Slated to launch in October 2021, NASA’s Lucy mission will be the first space mission to study the Trojan asteroids, leftover building blocks of the solar system’s outer planets orbiting the Sun at the distance of Jupiter. The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity’s evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of our solar system. This artist’s impression shows Jovian Trojans, based on data from a 2012 study by NASA’s Wide-field Infrared Explorer, or WISE. The Jovian Trojans – asteroids that lap the Sun in the same orbit as Jupiter – are uniformly dark with a hint of burgundy color, and have…
