France-China Teamwork: SVOM Gamma Ray Astronomy Satellite Pre-launch

France-China Teamwork: SVOM Gamma Ray Astronomy Satellite Pre-launch

On Saturday, June 22, 2024, China successfully launched an astronomy satellite—the result of nearly 20 years of hard work between Chinese and French scientists. It will capture gamma-ray bursts that flicker like fireworks in the farthest reaches of the universe.

The satellite, the Space-based Multi-band Variable Object Monitor (SVOM), was launched by a Long March-2C rocket from the Xichang Satellite Launch Center in southwest China's Sichuan Province, according to the China National Space Administration (CNSA).

It is the most powerful satellite to carry out multi-band comprehensive observations of gamma-ray bursts to date. It will play an important role in scientific studies of high-energy astronomical phenomena.

The 930kg (2,050-pound) satellite, which took hundreds of scientists and engineers nearly two decades to develop, will orbit Earth at 625km (450 miles) above the ground to accurately measure the location and energy of distant, violent explosions known as gamma-ray bursts.

China is primarily responsible for the mission, launch, satellite and operations, and shared responsibility with France for the design and construction of the instruments and ground segment.

The French contribution was developed in partnership with research laboratories at the IRFU research institute at CEA, the French atomic energy and alternative energies commission, and at INSU, the national institute of universe science, and IN2P3, the national institute of nuclear and particle physics, both attached to the national scientific research centre CNRS.

Young Elliptical Galaxy NGC 3610 in Ursa Major | Hubble

Young Elliptical Galaxy NGC 3610 in Ursa Major | Hubble


At the center of this image is the elliptical galaxy NGC 3610. Surrounding the galaxy are a wealth of other galaxies of all shapes. There are spiral galaxies, galaxies with a bar in their central regions, distorted galaxies and elliptical galaxiesall visible in the background. In fact, almost every bright dot in this image is a galaxy—the few foreground stars are clearly distinguishable due to the diffraction spikes that overlay their images.

Distance: 70 million light years

NGC 3610 is of course the most prominent object in this image—and a very interesting one. Discovered in 1793 by William Herschel, it was later found that this elliptical galaxy contains a disc. This is very unusual, since discs are one of the main distinguishing features of spiral galaxies. NGC 3610 even hosts a remarkably bright disc.

The reason for the peculiar shape of NGC 3610 stems from its formative history. When galaxies are born, they usually resemble our galaxy, the Milky Way, with flat discs and spiral arms where star formation rates are high and are therefore very bright. An elliptical galaxy is generally a much more disordered object. It results from the merging of two or more disc galaxies. During these violent mergers most of the internal structure of the original galaxies is destroyed. The fact that NGC 3610 still shows a structure in the form of a bright disc implies that it formed only a relatively short time ago. The galaxy’s age has been put at around four billion years. It is an important object for studying the early stages of evolution in elliptical galaxies.

Chinese-built Reusable Rocket: 10-kilometer Vertical Return Test Successful

Chinese-built Reusable Rocket: 10-kilometer Vertical Return Test Successful





A Chinese reusable carrier rocket completed a 10-kilometer vertical return test Sunday, June 23, 2024. This was the largest vertical return test for a Chinese reusable carrier rocket. This successful vertical takeoff, vertical landing test demonstrates continued progress towards a reusable rocket. 

The test flight began at 13:00 and lasted for about six minutes. The 3.8-meter-diameter rocket, powered by three 70-tonne variable-thrust liquid oxygen-methane rocket engines, climbed to an altitude of about 12 kilometers before adjusting and descending. The rocket opened its landing pad supports at an altitude of 50 meters and landed slowly but stably on the pad.

This rocket development is led by the Shanghai Academy of Spaceflight Technology, a member of China Aerospace Science and Technology Corporation (CASC).

This is the first use of the self-developed highly-variable thrust liquid oxygen-methane rocket engine in a 10-kilometer return test, laying a solid foundation for the 4-meter diameter reusable rocket to be tested in 2025.

After this, the development team will carry out a 70-kilometer vertical return test.

This event is the latest marker among several competing Chinese efforts to match and exceed the capabilities of SpaceX and its Falcon 9 rocket for commercial and domestic use on a large scale, combined with rapid rates of rocket production in higher volumes at a lower cost. This will further reduce the costs of payload delivery to Earth orbit and beyond for humanity.

The Hockey Stick Galaxy: NGC 4656 in Canes Venatici | Mayall Telescope

The Hockey Stick Galaxy: NGC 4656 in Canes Venatici | Mayall Telescope


This image was obtained with the wide-field view of the Mosaic camera on the 4-meter Mayall Telescope at Kitt Peak National Observatory. NGC 4656, also known informally as the "hockey stick galaxy," is a distorted edge-on spiral galaxy. Its distinctive shape is due to a recent gravitational interaction with the galaxy NGC 4631. It is not yet certain, but these two galaxies may be in the early stages of merging. The faint object in the upper-left corner may not be part of the galaxy, but instead be a dwarf galaxy in the process of merging with NGC 4656. The image was generated with observations in the B (blue), V (green), I (orange) and Hydrogen-Alpha (red) filters. In this image, North is up, East is to the left.

The Nicholas U. Mayall Telescope is a four-meter (158-inch) reflector telescope in Arizona named after Nicholas U. Mayall. It saw first light on February 27, 1973, and was the second-largest telescope in the world at that time.

Pakistan & China: Dreaming of The Moon | ICUBE-Q Lunar Satellite Mission

Pakistan & China: Dreaming of The Moon ICUBE-Q Lunar Satellite Mission

China's Chang'e-6 far side Moon mission successfully carried the ICUBE-Q satellite, releasing it into lunar orbit on May 8, 2024. The 15.4-pound (7 kilogram) small satellite captured images of the Moon and Sun and collected magnetic field data.

The ICUBE-Q is among the first nano-satellites to travel into deep space. It is also the first satellite collaboration mission between the governments of Pakistan and China, as well as their universities.

To accomplish this, young people from Pakistan and China embarked on a collaborative journey, starting a new chapter in lunar exploration. They represent not only the future of their nations, but also a new hope for humanity's future space endeavors. Going from dream to reality, from Earth to the Moon, watch what is made possible when young people aspire and inspire in this short clip from the upcoming CGTN documentary "Back To the Far Side."

Pakistan launched its groundbreaking lunar mission aboard China's Chang'e-6 lunar probe on May 3, 2024. The Chinese probe launched on a Long March-5 Y8 carrier rocket from the Wenchang Spacecraft Launch Site in south China's Hainan Province.

The ICUBE-Q CubeSat satellite, designed and developed by Pakistan's Institute of Space Technology (IST) in collaboration with China's Shanghai Jiao Tong University (SJTU) and Pakistan's national space agency, SUPARCO, represents a milestone in space cooperation.

The launch was broadcast live on the Institute of Space Technology's website and media channels with viewers worldwide witnessing history in the making. For the many young students aspiring to explore the unknown, this historic day signified that their dream is about to come true.

"It all started from my childhood, basically, it looks really fascinated when I looked at the Moon continuously walking with us, and I usually stare at the Moon from my rooftop," said Malaika Khursheed, a student at the Institute of Space Technology.

ICUBE-Q is a symbol of mutual trust, and youngsters' exploration of the Moon.

"At the moment of the launch of the Pakistan and SJTU CubeSat, I'm very delighted to be part of this momentous occasion and I can't wait to watch the launch," said Chen Ye, a student from Shanghai Jiao Tong University.

In March 2024, students from Shanghai Jiao Tong University arrived in Pakistan to meet and train with their fellow Pakistani students. The Chinese team brought a copy of the satellite to Pakistan. It was the only time that both teams met and interacted in-person. Pakistani researchers spoke highly of the cooperation.

"Collaboration with China is really significant, it signifies global cooperation," said Syed Azish Ali Bukhari, a communication engineer and a research fellow at the IST.

"It truly gives a big boost to our young people so that they can look forward to such projects and even more complex and bigger projects in the future," said Qamar Ul Islam, director of the Space System Lab of IST.

CubeSats, renowned for their compact design and versatility, have transformed space exploration, empowering universities, research institutions, and commercial ventures to participate in cutting-edge missions at a fraction of the cost.

This collaborative endeavor underscores the deepening ties between Pakistan and China in the pursuit of scientific discovery beyond Earth's bounds.

The Chang'e-6 Mission's primary objective is to gather samples from the far side south pole region of the Moon for their return to Earth for the first time in human history.

Lynds Dark Nebula 1251 in Cepheus

Lynds Dark Nebula 1251 in Cepheus

Stars are forming in Lynds Dark Nebula (LDN) 1251. About 1,000 light-years away and drifting above the plane of our Milky Way galaxy, LDN 1251 is also less appetizingly known as "The Rotten Fish Nebula." The dusty molecular cloud is part of a complex of dark nebulae mapped toward the Cepheus flare region. Across the spectrum, astronomical explorations of the obscuring interstellar clouds reveal energetic shocks and outflows associated with newborn stars, including the telltale reddish glow from scattered Herbig-Haro objects hiding in the image. Distant background galaxies also lurk in the scene, almost buried behind the dusty expanse. This alluring view spans over four full moons on the sky, or 35 light-years at the estimated distance of LDN 1251.

Red Sprites Spotted off South African Coast | International Space Station

Close-up view of red sprites off South African Coast

High-resolution wide-view of red sprites off South African Coast

NASA astronaut Matthew Dominick: "Super lucky a few weeks ago when shooting a timelapse of a lightning storm off the coast of South Africa. One of the frames in the timelapse had a red sprite. A rare event. My knowledge is pretty much just from Wikipedia but I want to know more."

Red Sprites: These mysterious bursts of light in the upper atmosphere momentarily resemble gigantic jellyfish. One unusual feature of sprites is that they are relatively cold. They operate more like long fluorescent light tubes than hot compact light bulbs. In general, red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side.

Milky Way & Large Magellanic Cloud Galaxies+Aurora over Western Australia

Milky Way & Large Magellanic Cloud Galaxies+Aurora over Western Australia

Astrophotographer Trevor Dobson: "This is an 8 shot panorama of the recent Aurora event of May 11. In this shot you can see the Aurora Australis, aka the Southern Lights, with the Crux/Carina region of the Milky Way above it. The Large Magellanic Cloud is also visible on the far right centre of the image."

For many people, the aurora is a beautiful nighttime phenomenon that is worth traveling to Earth's polar regions just to observe. It is the only way for most people to actually experience space weather. 

Earth auroras have different names depending on the pole where they occur. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

NASA's Chandra X-ray Observatory Peers into Densest & Strangest Stars

NASA's Chandra X-ray Observatory Peers into Densest & Strangest Stars

Astronomers have taken an important step toward understanding examples of the densest and strangest objects in the Universe by using NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM-Newton. These results show that the interiors of neutron stars may contain a special type of ultra-dense matter that does not exist anywhere else in the universe.

Neutron stars are the dense cores that can form after massive stars collapse. They are so dense that a teaspoon of their matter weighs about a trillion pounds.

The team in this new study analyzed previously released data from neutron stars to determine the so-called equation of state. This refers to the basic properties of the neutron stars including the pressures and temperatures in their interiors.

The authors used machine learning, a type of artificial intelligence, to compare the data to different equations of state. Their results imply that a significant fraction of the equations of state—the ones that do not include the capability for rapid cooling at higher masses—can be ruled out.

The researchers capitalized on neutron stars in the study being located in supernova remnants, including 3C 58. Since astronomers have age estimates of the supernova remnants, they also have the ages of the neutron stars that were created during the explosions that created both the remnants and the neutron stars. The astronomers found that the neutron star in 3C58 and two others were much cooler than the rest of the neutron stars in the study.

The team thinks that part of the explanation for the rapid cooling is that these neutron stars are more massive than most of the rest. Because more massive neutron stars have more particles, special processes that cause neutron stars to cool more rapidly might be triggered.

One possibility for what is inside these neutron stars is a type of radioactive decay near their centers where neutrinos—low mass particles that easily travel through matter—carry away much of the energy and heat, causing rapid cooling. Another possibility is that there are types of exotic matter found in the centers of these more rapidly cooling neutron stars.

These are objects that seem to just get more interesting the more scientists examine them!

Shenzhou-18 Crew Performs Health & Science Experiments | China Space Station

Shenzhou-18 Crew Performs Health & Science Experiments | China Space Station

The Shenzhou-18 crew has carried out a series of in-orbit experiments, physical exercises, and their first extravehicular activities over the past one and a half months since they entered the China's space station on April 26, 2024.

The three Chinese astronauts, Ye Guangfu, Li Cong and Li Guangsu, were sent to the orbiting space station for a six-month mission on April 25, from the Jiuquan Satellite Launch Center in northwest China.

Four zebrafish and hornwort were brought into orbit via the Shenzhou-18 spaceship for a life science and ecological experiment.

So far, the astronauts have successfully carried out two water samplings and one fish food container replacement. They have found abnormal directional behaviors of the zebrafish in microgravity, such as making rotational movements, going in circles and even swimming upside-down.

The water samples, fish eggs, and videos recording spatial movement behaviors of the zebrafish will be sent back to Earth for scientists to study the influence of the space environment on the growth and behaviors of vertebrates. This will provide references for research on material circulation of contained ecosystems in space.

The three astronauts completed the mission to replace samples of the container-free material cabinet. Previously, a number of key research projects had been carried out in the container-free cabinet, and many batches of experimental samples had been brought back to Earth for further tests and investigation.

The Shenzhou-18 crew also replaced a burner, plus vacuumized and exhausted waste gas on the combustion experimental cabinet.

The combustion experimental cabinet is one of the eight experimental cabinets carried by Mengtian, a lab module of China's space station. It can help scientists carry out in-depth research on basic science problems of combustion, space propulsion, fire safety for spacecraft, combustion pollution control, and other basic and applied technologies.

They have completed the installation of the conversion cable of the combustion solenoid valve, that can remotely controlled the switch of the solenoid valve, to accurately control fuel flow during experiments.

The crew also assembled and tested material extravehicular exposure of experimental equipment.

The astronauts in space face a series of physiological challenges brought about by the microgravity environment, including changes in the cardiovascular system, muscle atrophy, and bone density loss.

The three astronauts used an ultrasound diagnostic device to complete carotid artery ultrasound imaging and spectrum testing, and used an instrument to perform bone density testing.

They have performed regular weightlessness protection exercises, such as treadmill training and resistance training, so as to maintain good physical condition for the half-year mission.

The trio cooperated closely to complete the first spacewalk of their mission on May 28, 2024. They spent about 8.5 hours working outside the Tiangong space station and completed multiple tasks, including the installation of space debris protection devices. It was the longest spacewalk or extravehicular activity (EVA) record for China to date.

During the in-orbit stay of the Shenzhou-18 mission crew, they will take care of the space station and application payloads as planned, and carry out maintenance and inspection of the space station, so as to ensure the station's safe, reliable and efficient operation.

The crew will utilize scientific experiment cabinets and extravehicular payloads to conduct more than 90 experiments in the fields of basic physics in microgravity, space material science, space life science, space medicine and space technology.
