Astroscale Japan to lead Phase II of JAXA's Space Debris Removal Initiative
Thursday, 22 August 2024 17:36Astroscale Japan Inc. ("Astroscale Japan"), a subsidiary of Astroscale Holdings Inc. ("Astroscale"), has been awarded a contract by the Japan Aerospace Exploration Agency (JAXA) to lead Phase II of JAXA's Commercial Removal of Debris Demonstration (CRD2) program. This program is among the first global initiatives aimed at demonstrating the removal of large-scale debris from Earth's orbit. The co
New antenna design could pave the way for advanced 6G satellite networks
Thursday, 22 August 2024 17:36A team of researchers from the Beijing Institute of Technology has introduced an innovative design method for active multi-beam antennas, which could be a key component in future 6G satellite networks. This new approach seeks to address the significant limitations of traditional multi-beam antenna technologies, particularly in meeting the demanding requirements of Very High Throughput Satellite
Physicians work to help prevent vision loss associated with space travel
Thursday, 22 August 2024 16:29Physicians at the Medical College of Georgia at Augusta University are working with Polaris Dawn, the first of the Polaris Program's three human spaceflight missions, to better understand the eye changes many astronauts experience during spaceflight that can leave them with a wide range of symptoms once they return to Earth—from a new need for glasses to significant loss of vision.
The Polaris Program is a first-of-its-kind effort to rapidly advance human spaceflight capabilities while continuing to raise funds and awareness for important causes on Earth.
More than 70% of astronauts experience a phenomenon known as Spaceflight Associated Neuro-Ocular Syndrome, or SANS, according to NASA. The syndrome can have "a constellation of symptoms, including these changes in vision," said Matt Lyon, MD, director of the MCG Center for Telehealth.
Astronauts can experience other maladies as well when body fluids, such as cerebrospinal fluid, shift, which can lead to structural changes in the brain.
"The changes start happening on day one," said Lyon, who is also the J. Harold Harrison M.D. Distinguished Chair in Telehealth.
Juice’s navigation camera gets first taste of space
Thursday, 22 August 2024 14:50During this week’s lunar-Earth flyby, the Navigation Camera (NavCam) of ESA’s Jupiter Icy Moons Explorer (Juice) was tested out in space for the first time.
Novel strategy proposed for massive water production on the moon
Thursday, 22 August 2024 14:42Water plays a crucial role in human survival on the lunar surface, thus attracting extensive research attention. Prof. Wang Junqiang's team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has recently developed a new method of massive water production through a reaction between lunar regolith and endogenous hydrogen.
Research results of previous lunar explorations, like the Apollo and Chang'E-5 missions, have revealed the widespread presence of water on the moon. However, the water content in lunar minerals is extremely low, ranging from 0.0001% to 0.02%. It remains challenging to extract and utilize water in situ on the moon.
"We used lunar regolith samples brought back by the Chang'E-5 mission in our study, trying to find a way to produce water on the moon," said Wang.

Thursday, 22 August 2024 13:45Lessons from industry can inform satellite and spacecraft management in orbit
Thursday, 22 August 2024 13:32Most space mission systems historically have used one spacecraft designed to complete an entire mission independently. Whether it was a weather satellite or a human-crewed module like Apollo, nearly every spacecraft was deployed and performed its one-off mission completely on its own.
But today, space industry organizations are exploring missions with many satellites working together. For example, SpaceX's Starlink constellations include thousands of satellites. And new spacecraft could soon have the capability to link up or engage with other satellites in orbit for repairs or refueling.
Some of these spacecraft are already operating and serving customers, such as Northrop Grumman's mission extension vehicle. This orbiting craft has extended the lives of multiple communications satellites.

Thursday, 22 August 2024 10:46Cluster mission set to end with reentry over South Pacific
Thursday, 22 August 2024 07:00On 8 September 2024, the first of four satellites that make up ESA’s Cluster mission will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area.
This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.
This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in
Europe delivers for Artemis III

Juice trajectory reset with historic Lunar-Earth flyby
Wednesday, 21 August 2024 21:17ESA's Jupiter Icy Moons Explorer (Juice) has achieved a significant milestone by completing the world's first lunar-Earth flyby. This maneuver utilized Earth's gravity to set Juice on a course toward Venus, facilitating its journey to Jupiter by navigating through the inner Solar System. The spacecraft made its closest approach to the Moon at 23:15 CEST (21:15 UTC) on August 19, followed b
New data on radiation show missions to Jupiter's moon Europa are possible
Wednesday, 21 August 2024 18:19Scientists from NASA's Juno mission have developed the first complete 3D radiation map of the Jupiter system, including characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, and how the radiation environment is sculpted by the smaller Jovian moons orbiting near Jupiter's rings.
The work relies on data collected by Juno's star camera Advanced Stellar Compass (ASC) designed and built by Technical University of Denmark, and Stellar Reference Unit (SRU), which was built by Leonardo, S.p.A. in Florence, Italy. The two datasets complement one another, helping Juno scientists characterize the radiation environment at different energies.
