A Terrier-Improved Orion sounding rocket carrying students experiments for the RockOn! mission successfully launched from NASA’s Wallops Flight Facility Aug. 17 at 6 a.m. EDT. The launch carried experiments for Cubes in Space, RockOn!, and RockSat-C student programs. The sounding rocket reached an altitude of 103 miles (116.7 kilometers) before descending back down into the Atlantic Ocean via parachute. Teams will review the payload to return the experiments back to the students.

Two ospreys perch in their nest atop a marshalling area sign in front of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida in this photo from June 7, 2023. Kennedy shares a border with the Merritt Island National Wildlife Refuge. Merritt Island’s strategic location along the Atlantic Flyway provides a resting and feeding place for thousands of wading birds, shorebirds, and songbirds. More than 330 native and migratory bird species, along with 65 amphibian and reptile species, call Kennedy and the wildlife refuge home.

西北地区的野火

西北地区的野火

ByNASA中文

On August 8, 2023, the Moderate Resolution Imaging Spectroradiometer on NASA’s Aqua satellite captured this image of dense plumes of smoke streaming from dozens of large fires in the Northwest Territories. Several of these fires raged around Yellowknife, the province’s capital and largest city, where firefighters are conducting controlled burns around the city’s perimeter as a cautionary measure. These fires follow major outbreaks of fire in Alberta, British Columbia, Nova Scotia, and Quebec, in May, June, and July.

While wearing clean room suits, the Artemis II crew members (from left: NASA astronauts Victor Glover, Reid Wiseman, and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen) check out their Orion crew module inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida on Aug. 7, 2023. The crew module is undergoing acoustic testing ahead of integration with the European Service Module. Orion will carry the crew around the Moon in the first crewed mission on NASA’s path to establishing a long-term lunar presence for science and exploration under Artemis.

This artist’s concept from July 11, 1969, depicts the Apollo 11 lunar module Eagle landing on the surface of the Moon. Apollo 11 launched from Cape Kennedy on July 16, 1969, carrying commander Neil Armstrong, command module pilot Michael Collins, and lunar module pilot Edwin “Buzz” Aldrin. On July 20, the Eagle landed in the Sea of Tranquility with Aldrin and Armstrong inside, about four miles downrange from the predicted touchdown point and almost one-and-a-half minutes earlier than scheduled. Four hours later, Armstrong emerged from the Eagle and deployed the TV camera for the transmission of the event to Earth.

NASA’s Mars Phoenix Lander gathered images of itself for this selfie from June 5 through July 12, 2008, with its Surface Stereo Imager (SSI). This mosaic is made up of more than 100 different SSI pointings, with images taken through three different filters at each pointing. 15 years ago in August 2008, Phoenix completed its three-month mission studying Martian ice, soil, and atmosphere. The goals of the Phoenix Mars Lander were to study the history of water in the Martian arctic, search for evidence of a habitable zone, and assess the biological potential of the ice-soil boundary. More broadly, the lander was designed to determine whether life ever existed on Mars, characterize the climate and geology of the Red Planet, and to help prepare for…

In this image from April 2023, NASA’s Moonikin Campos, a manikin that flew on the Artemis I flight test beyond the Moon, enjoys a quiet moment during acceleration sled testing at Wright-Patterson Air Force Base in Ohio. Engineers put Moonikin Campos through acceleration sled testing to simulate contingency landings. Sled testing is a common method of testing restraint systems like automotive seats and seat belts to investigate their performance in collision situations. The tests are informing engineers’ understanding of what the experience of flying inside the agency’s Orion spacecraft will be like on crewed missions to the Moon beginning with Artemis II. During testing, the manikin wore the Orion Crew Survival System (OCSS) with a motion tracker on its forehead. Artemis astronauts will wear the…

In this image from June 2023, an engineer watches a development model rover during a test for NASA’s Cooperative Autonomous Distributed Robotic Exploration (CADRE) technology demonstration in the Mars Yard at NASA’s Jet Propulsion Laboratory in Southern California. The team tested a new wheel design, surface navigation software, and mobility capabilities, among other aspects of the project. NASA is sending a trio of these miniature rovers to the Moon to see how well they can cooperate with one another without direct input from mission controllers back on Earth. About the size of a carry-on suitcase, each of the four-wheeled rovers will drive to find a sunbathing spot, where they’ll open their solar panels and charge up. Then they’ll spend the lunar daytime conducting experiments designed…

哈勃望远镜瞥见一个闪烁的星系团

The glittering, glitzy contents of the globular cluster NGC 6652 sparkle in this star-studded image from the NASA/ESA Hubble Space Telescope. The core of the cluster is suffused with the pale blue light of countless stars, and a handful of particularly bright foreground stars are adorned with crisscrossing diffraction spikes. NGC 6652 lies in our own Milky Way galaxy in the constellation Sagittarius, just under 30,000 light-years from Earth and only 6,500 light-years from the galactic center. Globular clusters are stable, tightly gravitationally bound clusters containing anywhere from tens of thousands to millions of stars. The intense gravitational attraction between closely packed stars in globular clusters is what gives these star-studded objects their regular, spherical shape. This image combines data from two of Hubble’s most…
