Expedition 71 Crew Prepares for Launch in Kazakhstan | International Space Station

At the Baikonur Cosmodrome in Kazakhstan, the International Space Station’s Expedition 71 crew, NASA astronaut Tracy C. Dyson, Soyuz commander Oleg Novitskiy of Roscosmos (Russia) and Belarusian cosmonaut Marina Vasilevskaya participated in a variety of activities March 6-18, 2024, as they prepared for their upcoming mission. Dyson, Novitskiy and Vasilevskaya are set to launch March 21 from Baikonur in the Soyuz MS-25 spacecraft for a mission on the International Space Station. 

The backup Soyuz crewmates also attended the preparation activities, including NASA astronaut Don Pettit, Roscosmos cosmonaut Ivan Vagner and Anastasia Lenkova of Belarus. The footage includes the crew’s arrival in Baikonur, their Soyuz fit checks in the Cosmodrome’s Integration Facility and other training milestones.

Dyson will spend six months on the station, returning to Earth in September on Soyuz MS-25 while Novitskiy and Vasilevskaya will return to Earth April 2 on Soyuz MS-24 along with NASA astronaut Loral O’Hara, who has been aboard the orbital complex since last September.

The SOAR Telescope: A Southern Celestial Wayfinder in Chile

The SOAR Telescope: A Southern Celestial Wayfinder in Chile

The stars are perfectly aligned in this image of the Southern Astrophysical Research (SOAR) Telescope, located on Cerro Pachón in Chile and operated by Cerro Tololo Inter-American Observatory (CTIO), a Program of the National Science Foundation’s NOIRLab. The Milky Way galaxy appears to be pouring out of the open dome and spilling across the colorful sky. The wash of yellow and green near the horizon is a mix of airglow and light pollution from nearby villages. Where the two colors transition, the Large Magellanic Cloud and Small Magellanic Cloud shine through (lower left). However, near the center of this image is a truly notable grouping: the constellation Crux. Also known as the Southern Cross, it is discoverable by its red star (the top of the cross) and three nearby blue stars that form a cross shape. This grouping of stars has been a beacon for both European and Pacific Islander navigators for centuries. Its navigational use is akin to Polaris, but instead of directing people to the North Pole, Crux points—roughly—towards the South Pole.

NASA’s Double Asteroid Redirection Test (DART) spacecraft intentionally crashed into Dimorphos, the asteroid moonlet in the double-asteroid system of Didymos on September 26, 2022. This was the first planetary defense test in which an impact of a spacecraft attempted to modify the orbit of an asteroid. The SOAR Telescope imaged the more than 10,000 kilometers long trail of debris blasted from the surface of Dimorphos two days after the impact. These observations are allowing scientists to gain knowledge about the nature of the surface of Dimorphos, how much material was ejected by the collision, how fast it was ejected, and the distribution of particle sizes in the expanding dust cloud—for example, whether the impact caused the moonlet to throw off big chunks of material or mostly fine dust. Analyzing this information will help scientists protect Earth and its inhabitants by better understanding the amount and nature of the ejecta resulting from an impact, and how that might modify an asteroid’s orbit.

This gigantic 900-megapixel photo was taken as part of the NOIRLab 2022 Photo Expedition to all the NOIRLab sites. Tomas Slovinský, the photographer, is a NOIRLab Audiovisual Ambassador.

NASA statement: "We are mourning the passing of Thomas P. Stafford at the age of 93 (September 17, 1930—March 18, 2024). In December 1965, Stafford piloted Gemini VI, the first rendezvous in space, and helped develop techniques to prove the basic theory and practicality of space rendezvous. 

Later he commanded Gemini IX and performed a demonstration of an early rendezvous that would be used in the Apollo lunar missions, the first optical rendezvous, and a lunar orbit abort rendezvous. 

He served as the commander of the Apollo 10 ‘dress rehearsal’ mission preparing for the first Moon landing and as Apollo commander of the Apollo-Soyuz Test Project (ASTP) mission, a joint space flight culminating in the historic first meeting in space between American Astronauts and Soviet Cosmonauts, which ended the International space race.

Throughout his career, Stafford helped us push the boundaries of what's possible in air and space, flying more than 100 different types of aircraft."

China's First Commercial Spaceport: Ready for Rocket Launches by June 2024

China's First Commercial Spaceport: Ready for Rocket Launches by June 2024

China's first commercial spacecraft launch site in Wenchang City of south China's Hainan Province will be capable of launches by June 2024, said Zhang Jie, deputy general manager of Beijing Long March Tian Min Hi-Tech Co., Ltd. Construction of the No. 1 launch pad started in July 2022, and the equipment-installation phase was completed by the end of 2023.

Technical personnel from China Academy of Launch Vehicle Technology (CALT) are currently conducting joint debugging of the hydraulic, measurement and control and electromechanical systems at the No. 1 launch pad. Over 20 technical experts from across the country have also been dispatched to the launch site to ensure the timely progress of the project construction.

"We are working extratime to carry out several major processes, including adjustment, optimization, and debugging. We provide skillful support for on-site debugging and track the entire process from stem to stem to ensure the safety, reliability, and controllability of our shakedown test," said Zhang Jie, deputy general manager of Beijing Long March Tian Min Hi-Tech Co., Ltd., a subsidiary of CALT.

The No. 1 launch pad is a dedicated launch station for the Long March-8 carrier rockets, containing 11 types of equipment and facilities such as fixed service towers and launch pads. To ensure high efficiency, a series of technological innovations have been adopted in the design and product selection of the launch site to meet the demand for continuous launching of rockets within a short period of time.

"For commercial space launches, efficiency and cost-effectiveness are crucial. Therefore, we have made significant innovations in this regard. For example, we have made improvements to the tower structure behind me in terms of the deflector cone. Now, this deflector cone can be restored within seven days, enabling the capability for a second launch," Zhang said.

Currently, the equipment commissioning for No. 1 launch pad is expected to be completed by the end of March, while the installation of equipment for No. 2 launch pad is currently underway.

"Next, we will proceed with matchmaking between launch pads and propellant gas supply system, as well as the integration testing of sub-systems. In the subsequent stage, we will conduct comprehensive testing to the whole system. It is expected that the two launch pads will have basic launch capabilities by the end of June," said Ge Lixin, director of the engineering and equipment department, Hainan International Commercial Aerospace Launch Co., Ltd.

Based on the commercial space launch site, Hainan plans to accelerate the formation of commercial space industry clusters focusing on the rocket industry supply chain, satellite industry supply chain, and the data management chain.

Pan of The Spider Galaxy: UGC 5829 | Hubble Space Telescope

Pan of The Spider Galaxy: UGC 5829 | Hubble Space Telescope

This gauzy-looking celestial body is UGC 5829, an irregular galaxy that lies about 30 million light-years away. Despite there not being many observations of this relatively faint galaxy, it has the distinction of having a descriptive soubriquet: the Spider Galaxy. Perhaps the distorted galactic arms with their glowing, star-forming tips bring to mind the clawed legs of an arachnid. Somewhat confusingly, there is another, very similarly nicknamed but otherwise entirely distinct, galaxy known as the Spiderweb Galaxy. This galaxy has also been more extensively imaged (notably by Hubble), despite the fact that it lies about 300 times further from Earth than the Spider Galaxy does. 

Fortunately, correct galaxy identification does not depend on casual given names. Rather, known galaxies are recorded in at least one catalogue—and often in several—such as the Uppsala General Catalogue of Galaxies, which gives the Spider Galaxy its more formal title of UGC 5829. This same galaxy also has several different designations in various other catalogues: it is, for example, LEDA 31923 in the Lyon-Meudon Extragalactic Database; MCG+06-24-006 in the Morphological Catalogue of Galaxies; and SDSS J104242.78+342657.3 in the Sloan Digital Sky Survey Catalogue. The Spiderweb Galaxy is not recorded in all of the same catalogues—each is necessarily limited in scope— but it is included in the LEDA catalogue as LEDA 2826829. It is evidently simpler to not conflate the dull but distinct names LEDA 31923 and LEDA 2826829, than the fun but easily confused Spider and Spiderweb!

Image Description: An irregular galaxy, consisting of a large central body of dull-colored stars with distorted arms around it. The arms are spotted with brightly glowing pink areas where stars are forming, and bluish gas that is brighter than the galactic core. Two large arms flank the left and right of the body, and smaller streams of stars emerge from the top. Other, distant, galaxies can be seen on the edges of the image.

Panning over Dwarf Galaxy IC 3476 in Coma Berenices | Hubble

Panning over Dwarf Galaxy IC 3476 in Coma Berenices | Hubble

This image features IC 3476, a dwarf galaxy that lies about 54 million light-years from Earth in the constellation Coma Berenices. Whilst this image does not look very dramatic—if we were to anthropomorphize the galaxy, we might say it looks almost serene—the actual physical events taking place in IC 3476 are highly energetic. In fact, the little galaxy is undergoing a process known as ram pressure stripping. This is driving unusually high levels of star formation within regions of the galaxy itself.

We tend to associate the letters ‘ram’ with the acronym RAM, which refers to Random Access Memory in computing. However, ram pressure has a totally distinct definition in physics. It is the pressure exerted on a body when it moves through a fluid, due to the overall resistance of the fluid. In the case of entire galaxies experiencing ram pressure, the galaxies are the ‘bodies’ and the intergalactic or intracluster medium (the dust and gas that permeates the space between galaxies, and for the latter the spaces between galaxies in clusters) is the ‘fluid’. 

Ram pressure stripping occurs when the ram pressure results in gas being stripped from the galaxy. This stripping away of gas can lead to a reduction in the level of star formation, or even its complete cessation, as gas is absolutely key to the formation of stars. However, the ram pressure can also cause other parts of the galaxy to be compressed. This can actually boost star formation. It seems to be taking place in IC 3476. There appears to be absolutely no star formation going on at the edge of the galaxy bearing the brunt of the ram pressure stripping, but then star formation rates within deeper regions of the galaxy seem to be markedly above average. 

Image Description: A dwarf spiral galaxy. The center is not particularly bright and is covered by dust, while the outer disc and halo wrap around as if they were swirling water. Across the face of the galaxy, an arc of brightly glowing spots marks areas where new stars are being formed. The galaxy is surrounded by tiny, distant galaxies on a dark background.

NASA Artemis Astronaut Training: Behind The Scenes | Johnson Space Center

NASA Artemis Astronaut Training: Behind The Scenes | Johnson Space Center

Prior to their recent graduation, NASA’s ten astronaut candidates spent the past two years in basic training to become flight-eligible astronauts. Since their selection in December 2021, they have been learning International Space Station systems, training for spacewalks, practicing robotic operations, operating T-38 jets, studying wilderness survival, and much more. Two astronauts from the United Arab Emirates (UAE) have trained alongside them every step of the way. 

The bulk of their training took place at NASA’s Johnson Space Center in Houston, Texas. The completion of this training signifies their graduation as flight-eligible astronauts, meaning they are now able to be selected to go to space. Once they are assigned a mission to space, the astronaut will continue their training at a deeper level.

China Prepares to Launch Second Lunar Communications Satellite: Queqiao-2

China Prepares to Launch Second Lunar Communications Satellite: Queqiao-2

The Long March-8 Y3 rocket will launch the Queqiao-2 relay satellite from the Wenchang Spacecraft Launch Site, Hainan Province, China. On March 17, 2024, the Long March-8 Y3 rocket and the Queqiao-2 relay satellite (Magpie Bridge-2) were vertically transferred to the launching area. Queqiao-2 will provide communications services for the Chang’e-4, Chang’e-6, Chang’e-7 and Chang’e-8 lunar missions.

Countdown has begun for the launch of China's relay satellite Queqiao-2 as the combination of the satellite and the Long March 8 Y3 carrier rocket was vertically transported on Sunday to the launch area at the Wenchang Spacecraft Launch Site in the southern province of Hainan, said the China National Space Administration.

The final assembly and testing of the satellite for communications between the far side of the moon and the Earth has been completed after it was transported to the launch site in late February.

After being moved to the launch pad, engineers will carry out rocket check, the joint test work and the propellant filling before the launch in coming days.

Queqiao-2, or Magpie Bridge-2, will serve as a relay platform for the fourth phase of China's lunar exploration program, providing communications services for Chang'e-4, Chang'e-6, Chang'e-7, and Chang'e-8 missions.

Queqiao-1 was launched in 2018 and supported the Chang'e 4 lunar farside mission.

St. Patrick’s Aurora Illuminates the Night Sky of Alaska

St. Patrick’s Aurora Illuminates the Night Sky of Alaska

As we move closer to the peak of solar cycle 25, activity on the Sun is ratcheting up. One sign of that in Earth’s atmosphere in the form of a dazzling display of the aurora borealis, or northern lights.

This majestic image of the dazzling green lights of the aurora borealis was captured on March 17, 2015, around 5:30 a.m. EDT in Donnelly Creek, Alaska.

A Starry Night Sky over Gemini North Observatory in Hawaii

A Starry Night Sky over Gemini North Observatory in Hawaii

It is easy to assume that the deep void of outer space is completely dark, given the massive distances between celestial objects, but with the proper technique the truer count of all these objects becomes visible. Gemini North, one half of the International Gemini Observatory, operated by the National Science Foundation’s NOIRLab, beholds this ethereal view of the brimming sky. With our naked eyes, we can see about 6,000 stars, out of around 200 billion in the Milky Way. And this does not include many other astronomical objects!

At the bottom of this image, the dense cloud deck below Gemini North’s position suppresses light pollution from neighboring cities. This blanket facilitates a substantially darker and clearer night, and light from fainter stars can more easily be captured. Appearing like a reflection of the clouds, the Milky Way itself is visible on the Hawaiian horizon. Also at the horizon, a bright band glows from the right half of the image—this is sunlight reflecting off of interplanetary dust, creating zodiacal light. On the opposite side of the horizon shines a splash of backscattered sunlight called the gegenschein.

The 8.1-meter diameter optical/infrared North Gemini Telescope is located on Hawaii‘s Maunakea as part of the international community of observatories built to take advantage of the superb atmospheric conditions on this long-dormant volcano that rises about 4,214 meters (13,825 feet) into the dry, stable air of the Pacific.

The Seagull Nebula

The Seagull Nebula

A broad expanse of glowing gas and dust presents a bird-like visage to astronomers from planet Earth, suggesting its popular moniker: the Seagull Nebula. This portrait of the cosmic bird covers a 2.5-degree wide swath across the plane of the Milky Way, near the direction of Sirius, alpha star of the constellation of the Big Dog (Canis Major) at an estimated 3,800 light-year distance. 

Of course, the region includes objects with other catalog designations: notably NGC 2327, a compact, dusty emission, and reflection nebula with an embedded massive star that forms the bird's head. Likely part of a larger shell structure swept up by successive supernova explosions, the broad Seagull Nebula is cataloged as Sh2-296 and IC 2177. 

The prominent bluish arc below and right of center is a bow shock from runaway star FN Canis Majoris. Dominated by the reddish glow of atomic hydrogen, this complex of gas and dust clouds with other stars of the Canis Majoris OB1 association spans over 200 light-years.

China Space Station Retrieves over 400 Material Samples after Space Exposure

China Space Station Retrieves over 400 Material Samples after Space Exposure

A robotic arm on China's Tiangong space station successfully transferred an extravehicular experiment facility alongside with 407 material samples from outside the station's Wentian lab module to the station interior on Thursday, March 14, 2024. In order to study the stability, reliability, and longevity of these materials in space applications, the samples were moved outside of the space station on March 8, 2023, to be exposed to the space environment with high radiation levels, high vacuum levels, and wide temperature fluctuations.

According to researchers from the Technology and Engineering Center for Space Utilization at the Chinese Academy of Sciences (CSU), the astronauts are scheduled to transfer the retrieved assembly to the Mengtian lab module on Friday. The disassembly and storage of the scientific experiment samples are then set to be conducted under the guidance of ground technicians.

"After the lab module returns to the space station, the astronauts will primarily disassemble these scientific samples and install them into our storage boxes. Later, with the manned spacecraft descending to the ground, the samples will be delivered to scientists for analysis and comparison," explained Fan Lianwen, an engineer at the center.

The first batch of materials for extravehicular exposure experiments include non-metallic materials, like memory polymer and solid lubrication, as well as metallic materials, such as magnesium alloy and porous copper.

New scientific experiment samples are planned to be transported to the Chinese Space Station in batches and several of them, like passive radiation refrigeration materials, polyimide fiber and optical fiber, have already been transported to the space station by the Tianzhou-7 cargo spacecraft. A new round of exposure experiments is planned for May this year.

The Shenzhou-17 crew, who arrived at the space station on Oct 26, 2023 for a six-month mission, will continue to carry out a range of space science experiments and technological tests as planned.

Shenzhou-17 is the sixth crew of three astronauts on a mission to the China Space Station. Shenzhou-17 is also the twelfth crewed and seventeenth flight overall of China's Shenzhou spaceflight program.
