"With over 34,000 large debris pieces in orbit and millions of smaller fragments, the threat of collisions and the #KesslerSyndrome looms large. International cooperation, stringent regulations, and technological solutions are proposed to address the crisis, emphasizing the need for a comprehensive global framework to ensure #SpaceSustainability for future generations."

Autotrophs are organisms which use pigments for photosynthesis by absorbing light at specific wavelengths. The dominant chlorophyll-a absorbs #light in the violet-blue (430nm) and red (660nm) wavelengths, but not green, which is why #algae is green. Phycocyanin, an accessory #pigment in #cyanobacteria, absorbs in those green wavelengths, so is blue in colour. This is why we can determine algae types from space.

Astrospace interview with Tim Flohrer, head of the European Space Agency's Space Debris Office: "What is actually making our job more difficult today compared to a few years ago, is the rapid increase of active satellites. ... The effort we have to put today in this coordination activities is enormous, and rapidly increasing. And the complexity of the process results also in increased collision risks."

"#Space startup Gravitics has been awarded a $60M contract by the US Space Force to develop an 'orbital carrier' that can deploy satellites from orbit. ... While many questions remain about what exactly this carrier could be capable of — unsurprising, considering the sensitive nature of the plans — it's yet another sign that the US military is looking to beef up its presence in orbit, highlighting a brewing 'space arms race.'"

AST SpaceMobile has announced plans to launch FM1, a second-generation BlueBird satellite. It is about 223 square meters in size, or three times larger than first-gen BlueBirds. They will likely be the brightest artificial objects in the night sky after the ISS.

China has practiced co-ordinated satellite maneuvers in space that resemble aerial #combat, according to US Space Force
Speaking at McAleese Defense Programs Conference, the vice chief of space operations General Michael Guetlein said the US is preparing to develop capabilities for off-planet warfare. Space Force needs to guarantee "space superiority," over China, Russia, and other nations, he opined.

"History provides us with valuable lessons, allowing us to learn from past mistakes. Despite the success of the Montreal protocol, the ozone layer is not expected to fully recover until 2066, meaning it will take an 80-year effort to restore what was harmed in just a few decades. "

The Center for Space Environmentalism (CSE) has launched!

CSE is a group of scholars and experts who inform and advocate for issues pertaining to the protection of the increasingly crowded space environment. It is intended in part to counter the prevailing narrative about the 'inevitable' commercial development and exploitation of outer space. We welcome dialog and interaction with anyone interested in these topics.

I am proud to participate in this effort with my colleagues @salvabara, @planet4589, @sundogplanets and others.

A tiny satellite has enabled quantum-encrypted information to be sent between China and South Africa, the farthest distance yet achieved for quantum communication.
The team’s system is drastically smaller and cheaper that previous attempts, and they think it represents a big step towards the creation of a global network of secure, quantum communication.

Bye Starlink...

There are reports that the brightness of some of the Chinese #Qianfan satellites is varying on short timescales. (e.g., https://www.satobs.org/seesat/Mar-2025/0049.html)

This behavior suggests that these satellites (and possibly others) from the second Qianfan launch are currently tumbling in orbit.
