Using a computational model to study how to land on a planet safely
Tuesday, 25 April 2023 14:00
When a lander descends toward the moon—or a rocky planet, asteroid, or comet—the exhaust plume of the rocket interacts with the surface, causing erosion and kicking up regolith particles. The resulting blanket of dusty debris can create a dangerous brownout effect, limiting visibility and potentially damaging the spacecraft or nearby equipment.
In the journal Physics of Fluids,, researchers from Chungnam National University, the University of Edinburgh, Gyeongsang National University, and the Korea Institute of Science and Technology Information developed a model to describe the interaction between a rocket plume and the surface of a planetary body in near-vacuum conditions.
Connecting the Dots | SES-Intelsat merger would face uphill regulatory struggle
Tuesday, 25 April 2023 13:42
Plenty of operational synergies await SES and Intelsat if the world’s largest fixed satellite service providers can craft a merger able to clear regulatory scrutiny.
The future of gravity is MAGIC
Tuesday, 25 April 2023 13:08
The latest European State of the Climate report states that, last year, Europe suffered its hottest summer on record. The heat and a persistent lack of rain caused drought which, at its peak, affected much of the continent. This not only illustrates the reality of climate change, but also how precarious our supply of freshwater can be, even in western Europe where the climate is relatively moderate.
By delivering frequent and accurate gravity measurements, a new space mission called MAGIC, a cooperation between ESA and NASA, will help make the important task of managing our
SOHO chases asteroid's tail
Tuesday, 25 April 2023 13:00
The ESA/NASA SOHO observatory has overturned 14 years of thinking about the strange Sun-skirting ‘rock comet’ known as Phaethon that could reopen the mystery of how the Geminid meteor shower was born.
Tokyo company aims to be 1st business to put lander on moon
Tuesday, 25 April 2023 12:07
A Japanese company is about to attempt what no other private business has done: land on the moon.
Tokyo's ispace company put its own spacecraft into orbit around the moon a month ago.

Hydrosat received $20 million in government grants and investment for its campaign to measure water stress in plants and other indicators of climate change.
Quantum Space moves up development of Ranger transfer vehicle
Tuesday, 25 April 2023 10:30
Quantum Space is accelerating work on a transfer vehicle designed to take payloads to both geostationary orbit and cislunar space to support growing demand from commercial and government customers.
Viper and T-Rex on double rocket launch
Tuesday, 25 April 2023 10:11
Not one, but two rocket launches with ESA-led experiments are flying to the edge of space just a week apart, providing unique data to researchers eager to learn more about fundamental physics, semiconductor production, the formation of planets and how our immune cells react to spaceflight.
UAE probe offers unprecedented view of Mars moon
Tuesday, 25 April 2023 10:06
The United Arab Emirates' Hope space probe on Monday revealed Mars' smaller moon Deimos in unprecedented detail, shedding new light on the origin of the mysterious lumpy satellite.
The probe, the Arab world's first interplanetary mission, has been orbiting Mars for two years, regularly flying past Deimos and its big sibling moon Phobos.
It came within 110 kilometres (68 miles) from Deimo L3Harris awarded $145M to modernize US Space Domain Awareness capabilities
Tuesday, 25 April 2023 10:06
L3Harris Technologies (NYSE:LHX) announced the award of option year four of the Maintenance Of Space Situational Awareness Integrated Capabilities (MOSSAIC) program. The $145 million contract from the U.S. Space Force continues the modernization and sustainment of critical space infrastructure enabling the Space Force core competency of Space Domain Awareness (SDA).
In support of the U.S. Moon shot: Japan firm to attempt historic lunar landing
Tuesday, 25 April 2023 10:06
A Japanese space start-up will attempt Tuesday to become the first private company to put a lander on the Moon.
If all goes to plan, ispace's Hakuto-R Mission 1 lander will start its descent towards the lunar surface at around 1540 GMT.
It will slow its orbit some 100 kilometres above the Moon, then adjust its speed and altitude to make a "soft landing" around an hour later.
Success Fleet Space Technologies secures Australian defence space command contract
Tuesday, 25 April 2023 10:06
Fleet Space Technologies, an Australian space technology company, has signed a AUD$6.4 million contract with Australia's Defence Space Command. The agreement marks the company's first foray into the defence sector and will see Fleet's next-generation Centauri satellites used to develop and demonstrate a Low Earth Orbit (LEO) satellite communications system.
The program, named ASCEND2LEO, w Mars reveals liquid core as scientists measure first seismic waves
Tuesday, 25 April 2023 10:06
Scientists have confirmed that Mars' core is liquid as seismic wave measurements have given valuable first-time clues about how the Red Planet was formed.
The findings, published in the Proceedings of the National Academy of Sciences, show Mars' core is a completely liquid iron-alloy core with high percentages of sulfur and oxygen, unlike Earth's core, which is a combination of a liquid Teasing strange matter from the ordinary

In a unique analysis of experimental data, nuclear physicists have made the first-ever observations of how lambda particles, so-called "strange matter," are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). What's more, these data hint that the building blocks of protons, quarks and gluons, are capable of marching through the atomic nucleus in pairs called d Tracking changes to water, ecosystems, land surface
