Shenzhou-19 Crew Launch Scheduled for Oct. 30, 2024 | China Space Station

China's Shenzhou-19 crewed spacecraft is scheduled to be launched no earlier than at 04:27 Wednesday, October 30, 2024, (Beijing Time) from the Jiuquan Satellite Launch Center in the country's northwest, the China Manned Space Agency (CMSA) announced on Tuesday.

Lin Xiqiang, spokesman of the agency, announced this while briefing the media on the main tasks of the Shenzhou-19 mission.

"As evaluated and decided by the mission headquarters, the Shenzhou-19 spaceship is scheduled to be launched at 04:27 on Oct 30 Beijing Time. Crew members are astronauts Cai Xuzhe, Song Lingdong and Wang Haoze, with Cai Xuzhe as the commander," Lin said.

"Astronaut Cai Xuzhe has participated in the Shenzhou-14 space flight mission. Song Lingdong and Wang Haoze, among the third batch of Chinese astronauts, were born in the 1990s and will carry out a space flight for the first time. Song Lingdong was a former air force pilot before being selected as an astronaut and Wang Haoze previously served as a senior engineer at the Academy of Aerospace Propulsion Technology under the China Aerospace Science and Technology Corporation. She is currently China's only female spaceflight engineer and will become the third Chinese woman to embark on a crewed spaceflight mission," he said.

The three astronauts will take over command of China’s Tiangong space station from the Shenzhou-18 crew currently in orbit and will spend about six months in space.

Shenzhou-19 is the 33rd flight mission of China's crewed space program, and the 4th manned mission during the application and development stage of China's space station.

The Shenzhou-19 spacecraft, sitting atop a Long March-2F carrier rocket, has been transferred to the launching area, with pre-launch function checks and joint tests conducted to ensure the spaceship's readiness.

NASA Perseverance Mars Rover Drive Path Animation | JPL

This animated orbital-map view shows the route NASA’s Perseverance Mars rover has taken since its February 2021 landing at Jezero Crater to July 2024, when it took its “Cheyava Falls” sample. As of October 2024, the rover has driven over 30 kilometers (18.65 miles), and has collected 24 samples of rock and regolith as well as one air sample.

NASA’s Perseverance Mars rover is currently negotiating a steeply sloping route up Jezero Crater’s western wall with the aim of cresting the rim in early December 2024.

“Mars rovers have driven over steeper terrain, and they’ve driven over more slippery terrain, but this is the first time one had to handle both—and on this scale,” said the Jet Propulsion Laboratory’s Camden Miller, who was a rover planner, or “driver,” for Curiosity and now serves the same role on the Perseverance mission. “For every two steps forward Perseverance takes, we were taking at least one step back. The rover planners saw this was trending toward a long, hard slog, so we got together to think up some options.”

NASA's Perseverance rover landed on Mars in 2021 carrying 43 tubes for collecting samples from the Martian surface. So far, Perseverance has sealed and cached 24 samples of rock and regolith (broken rock and dust), plus one atmospheric sample and three witness tubes.

Planets Beware: NASA Finds Star Cluster Danger Zones | NASA Chandra

Planets Beware: NASA Finds Star Cluster Danger Zones | NASA Chandra

Most stars form in collections or groups, called clusters or associations, that include very massive stars. These giant stars send out large amounts of high-energy radiation, which can disrupt relatively fragile disks of dust and gas that are in the process of coalescing to form new planets.

A team of astronomers used NASA’s Chandra X-ray Observatory, along with ultraviolet, optical and infrared data, to show where some of the most treacherous places in a star cluster may be, where planets’ chances to form are diminished.

The target of the observations was Cygnus OB2, which is the nearest large cluster of stars to our Sun — at a distance of about 4,600 light-years. Cygnus OB2 contains hundreds of massive stars as well as thousands of lower-mass stars.

Astronomers used Chandra observations to map out the diffuse X-ray glow in between the stars and create a catalog of the young stars in the cluster. They then combined this catalog with others using optical and infrared data to create the best census of young stars yet in Cygnus OB2.

The researchers found that there is a lot of high-energy radiation produced by stars and planets in these crowded stellar environments. They determined that the X-rays plus intense ultraviolet light in Cygnus OB2 would have a devastating impact on planetary disks and systems in the process of forming there.

How would this happen? Planet-forming disks around stars naturally fade away over time. However, if these disks are close to massive stars that pump out lots of X-ray and ultraviolet radiation, this process of the disk destruction is accelerated. Instead of taking 5 or 10 million years, the disks around these giant stars are wiped out much sooner, possibly before planets have had time to form. The disks also disappear more quickly in regions where the stars are more closely packed together.

Sun Melts Comet C/2023 A3 (Tsuchinshan–ATLAS) | ESA SOHO Spacecraft

Sun Melts Comet C/2023 A3 (Tsuchinshan–ATLAS) | ESA SOHO Spacecraft

"Today, our solar system has one less comet." Comet ATLAS (C/2024 S1) "melted away" on Monday, Oct. 28, 2024, when it passed within 0.008 astronomical units (AU) of the Sun. Coronagraphs onboard the European Space Agency's Solar and Heliospheric Observatory (SOHO) witnessed the final moments. In this animation, an opaque occulting disk covers the Sun, blocking its glare to produce an artificial eclipse. This allowed SOHO's digital cameras to see the comet only 550,000 km from the surface of the sun.

Comet Tsuchinshan–ATLAS was categorized as a Kreutz sungrazer. These are a family of comets made up of fragments from the breakup of a single giant comet around a thousand years ago. SOHO has discovered thousands of them—almost all eventually disintegrate near the Sun.

Comet Tsuchinshan–ATLAS first appeared in September 2024 when an outburst brightened the comet, making it appear larger than average Kreutz fragments. Many astronomers hoped it would survive the Sun and put on a magnificent display like the Kreutz Comet Ikeya-Seki did in 1965. Not this time.

C/2023 A3 (Tsuchinshan–ATLAS) was a comet from the solar system's Oort cloud discovered by the Purple Mountain Observatory east of Nanjing, China, on January 9, 2023, and independently found by the automated Asteroid Terrestrial-impact Last Alert System (ATLAS) in South Africa on February 22, 2023. ATLAS is funded by NASA's planetary defense office, and developed and operated by the University of Hawaii's Institute for Astronomy. C/2023 A3 passed perihelion (closest approach to the Sun) at a distance of 0.39 AU (58 million km; 36 million miles) on September 27, 2024.

The Oort cloud is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose honor the idea was named. Oort proposed that the bodies in this cloud replenish and keep constant the number of long-period comets entering the inner Solar System—where they are eventually consumed and destroyed during close approaches to the Sun.

Shenzhou-18 Crew Prepares for Earth Return | China Space Station

Shenzhou-18 Crew Prepares for Earth Return | China Space Station

The Shenzhou-18 crew aboard China's orbiting Tiangong space station is preparing for their return mission while wrapping up remaining experiments. The three astronauts, Ye Guangfu, Li Cong, and Li Guangsu, were sent into space for a six-month mission in April this year. Their return will take place after completing a handover with the Shenzhou-19 members at the space station.

Over the past week, the astronauts continued to carry out experiments in space material science, microgravity fluid physics and combustion science. They replaced the plug-in burner of a combustion cabinet gas experiment and samples from a fluid physics experiment cabinet as planned.

In addition, the crew members completed experimental tasks related to the study of astronaut psychological and behavioral ability.

In terms of emergency decision-making research, they used test software to complete basic cognitive ability tests, risk cognition tests, decision-style tests, and comprehensive decision-making tasks. The ground staff used the test results to carefully evaluate the astronauts' in-orbit emergency decision-making ability and to measure influential  factors, such as in-orbit time, emotional states, and workload on the test results for emergency decision-making abilities.

In terms of in-orbit emotion recognition and evaluation research, the ground staff evaluated the emotional state of the astronauts through questionnaires, color preference tests, and emotional picture tests. They also explored the impact of medium- and long-term flight on the emotional state of astronauts.

Furthermore, the Shenzhou-18 crew conducted rendezvous and docking training. 

The astronauts used the metacognitive training system to complete image recognition and operation testing under different initial conditions, confirming the overall accuracy and reliability of their operational skills.

In preparation for the return, the crew completed in-orbit data cleaning and transmission to ground stations, material inventory and sorting, equipment status checking, and they gathered items for return.

As for regular medical examinations, the astronauts had basic physical checks, ambulatory electrocardiographic blood pressure monitoring, 12-lead Electrocardiogram tests, plus non-invasive cardiac function and ultrasound examinations.

While keeping up physical exercise, the astronauts used microgravity physiological protective equipment, including acupoint stimulation clothing and bone loss countermeasure instruments to reduce the health impacts of their long-duration mission in a microgravity environment.

Spiral Galaxy NGC 4414: Revisiting an Old Beauty | Hubble Space Telescope

Spiral Galaxy NGC 4414: Revisiting an Old Beauty | Hubble Space Telescope

This image from the NASA/European Space Agency Hubble Space Telescope shows an unbarred spiral galaxy located roughly 51 million light-years away from Earth in the constellation Coma Berenices.

The image features Hubble data from 1995 and 1999 that was captured as part of the telescope’s primary missions to determine the distance between galaxies. This was achieved as part of an ongoing research effort to study Cepheid variable stars. Cepheids are a special type of variable star with very stable and predictable brightness variations. The period of these variations depends on physical properties of the stars, such as their mass and true brightness. This means that astronomers, just by looking at the variability of their light, can determine the Cepheids' physical nature. This then can be used very effectively to determine their distance. This is why cosmologists call Cepheids 'standard candles'.

Astronomers have used Hubble to observe Cepheids, like those that reside in NGC 4414, with extraordinary results. The Cepheids have then been used as stepping-stones to make distance measurements for supernovae that can provide a measure for the scale of the Universe. Today, we know the age of the Universe to a much higher precision than before, thanks to the Hubble Space Telescope—around 13.7 billion years.

Image Description: A large spiral galaxy is seen tilted diagonally. The arms of the galaxy’s disc are speckled with glowing patches; some are blue in color, others are pink, showing gas illuminated by new stars. A faint glow surrounds the galaxy, which lies on a dark, nearly empty background. The galaxy's center glows in white.

Journey to The Great Peacock Globular Star Cluster: NGC 6752 | ESO

Journey to The Great Peacock Globular Star Cluster: NGC 6752 | ESO

This zoom video starts with a wide view of the central parts of the Milky Way galaxy and slowly closes in on the globular star cluster NGC 6752 in the southern constellation of Pavo (The Peacock). The final detailed image of the cluster is from the Wide Field Imager (WFI) on the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile.

Studies of this cluster by the European Southern Observatory’s Very Large Telescope (VLT) have unexpectedly revealed that many of the stars do not undergo mass-loss at the end of their lives.

NGC 6752 roams the halo of our Milky Way galaxy. Over 10 billion years old, NGC 6752 follows clusters Omega Centauri, 47 Tucanae, and Messier 22 as the fourth brightest globular star clusters in planet Earth's night sky. It holds over 100 thousand stars in a sphere about 100 light-years in diameter.

Telescopic explorations of NGC 6752 have found that a remarkable fraction of the stars near the cluster's core are multiple star systems. They also reveal the presence of blue straggle stars. These stars appear to be too young and massive to exist in a cluster whose stars are all expected to be at least twice as old as the Sun. The blue stragglers are thought to be formed by star mergers and collisions in the dense stellar environment at the cluster's core.

Astronaut Don Pettit's Water Ice Wafer 'Space Art' | International Space Station

NASA Astronaut Don Pettit: "Science, or should I say Nature, has a way of presenting surprising beauty if one is willing to look."

"Science and Art, or Art and Science; related subjects where it really doesn’t matter which comes first. So I have access to a freezer kept at -95 degrees centigrade (-140 F). What would you do with such a freezer in space?"

"I decided to grow thin wafers of water ice for no more reason than I’m in space and I can. Plus, I wanted to see how the freezing front behaves in 0g (without gravitational buoyancy, how does the freezing front push the tiny bubbles around). Here is one frame from a whole series. I photographed the ice . . . between crossed polarizers where I used a white (blank) laptop display as the illuminator/polarizer in conjunction with an analyzer (polarizing filter) I strategically packed in my bag of personal effects."

Polaris Dawn Mission Tribute

Polaris Dawn Mission Tribute

On Tuesday, September 10, 2024, SpaceX’s Falcon 9 launched the Polaris Dawn mission to orbit from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Polaris Dawn became the first crew to perform the first-ever spacewalk from Dragon, to travel the farthest (1,408 km) within Earth’s orbit since the completion of the Apollo program in 1972, and to test Starlink laser-based communications aboard Dragon. 

Additionally, the crew conducted approximately 36 experiments designed to better life on Earth and on future long-duration spaceflights. Polaris Dawn also "inspired the world with a global music moment before safely returning to Earth" on Sunday, September 15, 2024.

This was the first human spaceflight for Mission Pilot Kidd Poteet, Mission Specialist Sarah Gillis, and Mission Specialist and Medical Officer Anna Menon. Mission Commander Jared Isaacman previously flew to space as commander of Inspiration4. This has also been the first time two SpaceX employees have been part of a human spaceflight crew, providing valuable insight to future missions on the road to making life multiplanetary.
