China is preparing to launch its Tianwen-3 mission with the aim of returning samples from Mars by 2028, a Chinese space expert revealed on Thursday.
Liu Jizhong, the chief designer of the Mars sample-return mission, provided details during the 2nd International Deep Space Exploration Conference held in Tunxi, Huangshan City, Anhui Province, China.

A study conducted by Chinese researchers has confirmed that it is possible to continuously produce fiber materials from Martian soil, suggesting that "in-situ resource utilization" could be achieved in the construction of future Mars bases.

New observations of the outer Solar System using the Subaru Telescope have revealed the presence of several unexpected objects, suggesting that the region may be home to a much larger population of celestial bodies than previously believed. These findings could significantly alter our understanding of the Solar System's formation and its similarities to other planetary systems, potentially influ 3 Questions: Evidence for planetary formation through gravitational instability
Monday, 09 September 2024 13:37
Exoplanets form in protoplanetary disks, a collection of space dust and gas orbiting a star. The leading theory of planetary formation, called core accretion, occurs when grains of dust in the disk collect and grow to form a planetary core, like a snowball rolling downhill. Once it has a strong enough gravitational pull, other material collapses around it to form the atmosphere.

Planet formation has traditionally been described as a "bottom-up" process, where dust grains gradually clump together over millions of years, forming larger structures step by step. However, a competing theory suggests that planets can form much faster via a "top-down" process, where material in a protoplanetary disk fragments due to gravitational instability.

The shoebox-sized BurstCube satellite has observed its first gamma-ray burst, the most powerful kind of explosion in the universe, according to a recent analysis of observations collected over the last several months.
"We're excited to collect science data," said Sean Semper, BurstCube's lead engineer at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's an important mileston Leah Harris Joins SpaceNews as Marketing, Advertising Operations, and Audience Development Manager

Goodnight, Cluster: brilliant end to trailblazing mission
Monday, 09 September 2024 05:00
The first satellite in ESA’s Cluster quartet safely came back down to Earth last night in a world-first ‘targeted reentry’, marking a brilliant end to this remarkable mission.
The spacecraft, dubbed ‘Salsa’ (Cluster 2), reentered Earth’s atmosphere at 20:47 CEST on 8 September 2024 over the South Pacific Ocean. In this region, any risk of fragments reaching land are absolutely minimised.
During the last two decades Cluster has spent in space, it has provided invaluable data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast space weather. With this first-ever targeted reentry,

The first of four satellites that make up ESA’s Cluster mission is coming safely back down to Earth, marking a brilliant end to this remarkable mission.
The satellite’s orbit was tweaked back in January to target a region as far as possible from populated regions. This ensures that any spacecraft parts that survive the reentry will fall over open ocean.
During 24 years in space, Cluster has sent back precious data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast potentially dangerous space weather.
With this first ever targeted reentry, Cluster goes down in history
