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

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 Write a comment
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.

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

Satellite imagery is changing conservation as we know it. By being able to take an inventory of the Earth's surface and observe changes, we can begin to understand ecosystem dynamics in an unprecedented level of detail. Satellite imagery is already supplementing traditional conservation research methods, and in some cases is even replacing them.

Aerojet Rocketdyne recently received a $67 million contract award from Lockheed Martin to provide propulsion systems for the Orion spacecraft that are planned to launch on Artemis missions VI-V3. This new work is an extension of the 2019 Orion Production and Operations Contract (OPOC). The Orion spacecraft recently completed a successful test flight during NASA's Artemis I mission, proving it is Falcon Heavy delay affects space station manifest

Is sex in space being taken seriously by the emerging space tourism sector?
Monday, 24 April 2023 18:19 Write a comment
What would a human conception in space mean for the sector? That's the situation posed by an international group of scientists, clinicians and other interested parties, who have authored a consultative green paper led by David Cullen, Professor of Astrobiology & Space Biotechnology at Cranfield University.
It highlights that the emerging space tourism sector has not openly considered or discussed the risks of sex in space or prepared suitable mitigation approaches. It argues it is unrealistic to assume all future space tourists will abstain from sexual activities—opening the possibility of human conception and the early stages of human reproduction occurring in space.
This appears to pose several risks, those of a biological nature such as embryo developmental risks and those of a commercial nature such as liability, litigation, and reputational damage. The authors recommend that an open discussion is now needed within the space tourism industry to consider the risks.
Open discussion on human conception in space tourism is lacking
Professor Cullen from Cranfield University led the work. He said, "Our starting point was a throwaway comment about sex in space, but when we checked, we were surprised the sector has not openly considered the risks and this led to the study.
