When ESA's Gaia spacecraft scanned the Scorpius constellation and its ancient globular star cluster Messier 4, it captured something strange: a huge dark blob at the cluster's centre, 800 times more massive than our Sun.
It is normal for globular clusters to have dark centres made up of many dead stars. But the mass at the centre of Messier 4 looks different - despite being especially larg Iridium adds to constellation resilience with launch of spare satellites

Iridium Communications Inc. (NASDAQ: IRDM) has announced a key milestone in its long-term constellation resilience and redundancy planning, with the successful launch and deployment of five spare satellites. This launch brings the total number of spare Iridium satellites on orbit to 14. In total, 81 next-generation Iridium satellites were built, and 80 of them have now been deployed.

SmartSat Cooperative Research Centre (CRC), Australia's leading space research centre, has launched a new research program, 'Maya Nula', to develop Australian satellite Earth Observation (EO) capability with space sensor technology to advance Australia's agriculture industry.
The name Maya Nula, which translates to "eyes here, there, everywhere" in the Dharug language of the Eora nation, a Tonga underwater volcano disrupted satellite signals halfway around the world

An international team has used satellite- and ground-based ionospheric observations to demonstrate that an air pressure wave triggered by volcanic eruptions could produce an equatorial plasma bubble (EPB) in the ionosphere, severely disrupting satellite-based communications. Their findings were published in the journal Scientific Reports.

China's Mars rover Zhurong has provided key observational evidence of liquid water at low Martian latitudes, the warmest regions on the red planet, according to a new study published in the journal Science Advances this week.
Previous studies found evidence of a large amount of liquid water on early Mars, but dramatic climate changes led to very low pressure and water vapor content, making MAHLI works the night shift: Sols 3837-3838

Earth planning date: Monday, May 22, 2023- Curiosity successfully wrapped up the "Ubajara" drill campaign over the weekend with some imaging of the drill tailings. This Monday, we are planning two sols (Mars days) of activities to finish up at Ubajara before driving off in the coming sols. Most targeted science today is focused on bedrock target "Apetina," which is situated on the same block as Light shining through a wall experiment searches for dark matter

A mysterious signal is being sent by ESA’s ExoMars Trace Gas Orbiter on 24 May, a spacecraft orbiting the Red Planet looking for evidence of possible biological or geological activity.
As part of the global 'A Sign In Space' art project, it will strike huge antennas dotted around the globe; the Green Bank Telescope (West Virginia), the Medicina Radio Astronomical Station (Italy) and the Allen Telescope Array (California).
Early tests were conducted to ensure the feasibility of the endeavour and allow the ground-based observatories to fine tune their systems to be ready for the public event.

Satellites provide crucial insights into Arctic amplification
Wednesday, 24 May 2023 06:45 Write a comment
The Arctic, once again at the forefront of climate change, is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects known as Arctic amplification. As concerns continue to grow, satellites developed by ESA have become indispensable tools in understanding and addressing the complex dynamics at play and the far-reaching consequences for the environment and human societies.
