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.

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…

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…

Credits: NASA Photo / Lauren Hughes NASA has once again joined forces with the community in the continuing effort to fight COVID-19. 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.
