A major breakthrough in quantum technology was achieved in October 2024: the first-ever quantum satellite communication link between China and South Africa. The connection spanned a remarkable 12,900 km: the longest intercontinental quantum communication link established to date. The longest before this was 7,600 km and within the northern hemisphere only.
It was achieved with quantum key distribution, a method for a sender and receiver to share a secure key that they can use to safely send messages. Any interception during transmission leaves traces that can be detected. It involves sending single photons (tiny particles of light).
If someone tries to intercept the photons, the photons get disturbed because of quantum physics. Quantum physics is the study of matter and energy at the most fundamental level. Sender and receiver use only undisturbed photons, making the key to the message ultra secure. The key can be sent via optical fiber or free-space, including satellites.
Questions to inspire discussion.
Data and Autonomy.
📊 Q: Why is vision data valuable in AI development? A: Vision data is worth more than zero if you can collect and process yataflops and yataflops of data, but worthless without collection capabilities, making the world’s visual data valuable for those who can collect and process it.
🚗 Q: How does solving autonomy relate to AI development? A: Solving autonomy is crucial and requires tons of real world data, which necessitates tons of robots collecting real world data in the real world, creating a cycle of data collection and AI improvement.
Company-Specific Opportunities.
🔋 Q: What advantage does Tesla have in developing humanoid robots? A: Tesla has essentially built the robot’s brain in their vehicles, allowing them to transplant this brain into humanoid robots, giving them a massive head start in development.
We usually think of satellites as small objects orbiting planets or stars. But in the broader universe, galaxies themselves can have satellites—smaller galaxies bound by gravity that orbit a larger host, carrying with them stars, gas, dust, and dark matter.
Most of what we know about satellite galaxies comes from studying the Milky Way and other similarly large galaxies. But a new study led by Dartmouth astronomers broadens that understanding by exploring the satellites of dwarf galaxies—systems less than a tenth the size of the Milky Way.
The multi-institutional survey triples the number of dwarf galaxies surveyed for satellites, the researchers report in The Astrophysical Journal. The study identifies 355 candidate satellite galaxies, including 264 that were previously undocumented. The researchers suggest that 134 of these candidates are highly likely to be satellite galaxies.
3D Systems is collaborating with researchers from Penn State University and Arizona State University on two projects sponsored by NASA intended to enable groundbreaking alternatives to current thermal management solutions.
Severe temperature fluctuations in space can damage sensitive spacecraft components, resulting in mission failure. By combining deep applications expertise with 3D Systems’ leading additive manufacturing solutions comprising Direct Metal Printing (DMP) technology and tailored materials and Oqton’s 3DXpert® software, the teams are engineering sophisticated thermal management solutions for the demands of next-generation satellites and space exploration.
The project led by researchers with Penn State University, Arizona State University, and the NASA Glenn Research Center in collaboration with 3D Systems’ Application Innovation Group (AIG) has resulted in processes to build embedded high-temperature passive heat pipes in heat rejection radiators that are additively manufactured in titanium. These heat pipe radiators are 50 percent lighter per area with increased operating temperatures compared with current state-of-the-art radiators, allowing them to radiate heat more efficiently for high-power systems.

Amazon is hoping to get a good rhythm going with the launch and deployment of Project Kuiper, its 3,232-satellite internet constellation, which began operational flights in April. The tech giant said on Thursday that its nearly $140 million investment in Florida is a cornerstone to making that happen.
While shown in the background of photos and hinted at in other public relations materials during its first three launch campaigns, Amazon confirmed on July 24 that its payload processing facility (PPF) at the Kennedy Space Center (KSC) entered service back in April in time to support its first operational launch on a United Launch Alliance (ULA) Atlas 5 rocket.
“There is no better place than Florida’s Space Coast to fulfill Kuiper’s promise to bring broadband to unserved and underserved across the nation and world,” said Brian Huseman, Amazon’s vice president for public policy and community engagement, in a statement. “We are proud to make investments in Florida that will impact the local community and ultimately our customers. We look forward to our long-term partnership with Space Florida, NASA, Space Force, and state and local officials, as well as our launch providers and community partners.”
