The Karman Project: Building a cooperative future in space
The Karman Project is a non-profit foundation promoting peace and security in space through strategic international cooperation.
The project aims to unite global decision-makers to drive urgent, collaborative action for a sustainable and peaceful future in space — recognising the core role of international cooperation to secure the space sector's prosperity, and Earth's critical reliance on it.
The organisation fosters trust, cooperation and independent dialogue between global leaders in tech, science, business, politics, the arts and people in the space industry, who want to positively impact space.
The Space That Makes Us Human is a documentary film experience showcasing the mission, vision and voices of The Karman Project. It shifts into focus The Karman Project’s efforts in connecting the leaders of tomorrow to create positive impact in space, and transports this message of impact to a global audience.

How to become an astronaut with Rose Tasker
European Space Agency (ESA) astronaut, Andreas Mogensen
Born in Copenhagen, Denmark and selected as an ESA astronaut in 2009, Andreas completed extensive training in spacecraft operations, spacewalks, and extreme environment missions, including ESA CAVES and NASA NEEMO underwater missions. He has served as European liaison officer to NASA’s Johnson Space Center and participated in ESA’s Pangaea field science training.
Andreas has logged two spaceflights: the 10-day ‘iriss’ mission to the ISS in 2015, and the 2023 ‘Huginn’ mission on SpaceX Crew-7, where he became the first non-US pilot of the Crew Dragon and later the longest-serving European commander of the International Space Station.
NASA The Space Story: ROSAT (ROentgen SATellite) was an X-ray observatory developed through a cooperative program between Germany, the United States, and the United Kingdom.
The Chandra X-ray Observatory is the world's most powerful X-ray telescope. It has eight-times greater resolution and is able to detect sources more than 20-times fainter than any previous X-ray telescope.
NASA The Space Story: Fast Auroral SnapshoT (FAST or Explorer 70) was a NASA plasma physics satellite, and the second spacecraft in the Small Explorer program (SMEX). FAST was designed to observe and measure the plasma physics of the auroral phenomena which occur around both of Earth's poles.

Artemis II crewed lunar orbital mission confirmed by NASA is set for 2026
The announcement that while the target launch date for Artemis II remains April 2025, NASA will attempt to move that forward to February 2025, without compromising crew safety or mission success.
Four astronauts (Reid Wiseman, Commander; Victor Glover, Pilot; and Mission Specialists, Christina Koch & Jeremy Hansen) will venture around the Moon on Artemis II, the first crewed mission on NASA's path to establishing a long-term presence at the Moon for science and exploration through the Artemis program. The 10-day flight will help confirm systems and hardware needed for early human lunar exploration missions.
The mission builds on the success of the uncrewed Artemis I mission in 2022, and will demonstrate a broad range of capabilities needed on deep space missions. The Artemis II test flight will be NASA’s first mission with crew atop the SLS (Space Launch System) rocket and inside the Orion spacecraft.

Australian astrophysicists help prove Stephen Hawking’s landmark black hole prediction
A global team of astrophysicists, including Australians, has witnessed a collision between two black holes that was so loud, they were able to use it to test and prove Stephen Hawking’s Theory of Black Hole Thermodynamics.
The event, observed by the LIGO, Virgo, and KAGRA collaborations, involved two black holes merging to form a single, larger one, strikingly reminiscent of the historic first detection in 2015.
The research has been published in Physical Review Letters: doi.org/10.1103/kw5g-d732

Merging Black Holes and Gravitational Waves:
The Space Show is in conversation with Prof. Eric Thrane, School of Physics and Astronomy at Monash University, Clayton.
When scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) recently announced they had seen a bizarre pair of rapidly spinning black holes, the astrophysics community agreed it defied expectations — and may rewrite our understanding of the universe.
The announcement — “GW231123: A Binary Black Hole Merger” — describes unusually large black holes essentially smashing into each other. Each weighs more than 100 times more than our sun, and are spinning, where they would be expected to rotate more slowly, taking them to near the limits of what scientists understand to be physically possible.
The questions now are: How did these black holes form? Why are they so massive? And why are they spinning so fast?
