Innovative three legged landing system tested for small body exploration
Thursday, 02 November 2023 07:10
In an era where the bounds of space exploration are continually being stretched, a team from the Beijing Institute of Spacecraft System Engineering, Harbin Institute of Technology, and Polytechnic University of Milan have made significant strides in the development of landing mechanisms tailored for small celestial bodies. These environments pose unique challenges due to their low gravity and un Estimating depositional timing on Mars using cosmogenic radionuclide data

The U.S. Naval Research Laboratory's Melanized Microbes for Multiple Uses in Space Project, or MELSP, will use the International Space Station (ISS) to search for production of melanin variants and other useful biomaterials that can have applications both on Earth and in space. The mission is scheduled to launch in early November 2023.

The fifth batch of scientific experimental samples from China's Tiangong space station has arrived in Beijing, following the return of the Shenzhou XVI crew on Tuesday.
Samples of 19 scientific experiments, weighing around 25 kilograms, were brought back to Earth, including liver cells, protein and nucleic acid, Arabidopsis plants, rice seeds, radiation-resistant microbes and some chemical China places multipurpose satellite into space

China placed a multipurpose satellite into space on Wednesday morning, according to China Aerospace Science and Technology Corp.
The State-owned space conglomerate said in a news release the Tianhui 5 satellite was transported by a Long March 6A rocket that blasted off at 6:50 am from the Taiyuan Satellite Launch Center in Shanxi province.

NASA's Lucy spacecraft swoops past first of 10 asteroids on long journey to Jupiter
Wednesday, 01 November 2023 19:58
NASA's Lucy spacecraft on Wednesday encountered the first of 10 asteroids on its long journey to Jupiter.
The spacecraft on Wednesday swooped past the pint-sized Dinkinesh, about 300 million miles (480 million kilometers) away in the main asteroid belt beyond Mars. It was "a quick hello," according to NASA, with the spacecraft zooming by at 10,000 mph (16,000 kph).
Lucy came within 270 miles (435 kilometers) of Dinkinesh, testing its instruments in a dry run for the bigger and more alluring asteroids ahead.
Scientists develop a legged small celestial body landing mechanism for landing simulation and experimental test
Wednesday, 01 November 2023 19:54
Landing stably is a precondition for exploring a small celestial body in situ. The surface of a small celestial body frequently has weak gravity and is irregular, and the surface environment is unknown and uncertain. The landing mechanism tends to rebound and turn over, and the landing stability time is long. However, while most landing performance research has focused on lunar landing, there are differences between the surfaces of the moon and Mars.
Therefore, it important to study landing performance in different conditions in order to analyze the landing stability boundary, and to propose reasonable landing suggestions to support China's small celestial body exploration.
In a research article recently published in Space: Science & Technology, researchers from Beijing Institute of Spacecraft System Engineering, Harbin Institute of Technology, and Polytechnic University of Milan have established a simulation model of a landing mechanism under different landing conditions, analyzed the sensitivity of the key parameters affecting the landing performance, and verified correctness of the simulation via experimental tests, which can provide guidance for a landing mechanism to land stably on a small celestial body.
OSIRIS-REx flies on as OSIRIS-APEX to explore its second asteroid
Wednesday, 01 November 2023 18:00
After seven years in space and over 4 billion miles traveled, NASA's OSIRIS-REx mission successfully collected and delivered the first U.S. sample from a near-Earth asteroid. Yet, after all this time and travel, the spacecraft will not retire.
Instead, NASA extended the University of Arizona-led mission so that the spacecraft can be used to study another near-Earth asteroid named Apophis. The mission was renamed OSIRIS-APEX, short for OSIRIS-APophis EXplorer. An overview of the mission was published in The Planetary Science Journal.
OSIRIS-REx deputy principal investigator Dani DellaGiustina is now the principal investigator for the OSIRIS-APEX mission.
Twenty minutes after dropping the sample high above Earth's atmosphere on Sept. 24, the spacecraft fired its thrusters to put it on course to rendezvous with Apophis in 5½ years—just after Apophis makes its own close approach to Earth.
