Nuclear energy is key to American leadership in space

6 novembre 2025 à 14:00
Fission surface power

The future of American leadership in space will hinge on one factor: the ability to generate high power on orbit and on the surface of celestial bodies such as the moon. From a physics standpoint, nuclear energy offers the highest energy density available for spacecraft, enabling more efficient and compact power generation compared to solar. […]

How precise are satellite collision-avoidance platforms? Artificial intelligence is helping space trackers get a handle on increasingly congested orbits, but physics and math are only part of the challenge in a domain where debris, satellite maneuvers and solar weather can quickly rewrite the map. Companies tend to share their performance metrics only with customers, but […]

Demand has never been greater for the monitoring of objects in orbit and the coordination of their safe movement. The number of active satellites in low Earth orbit (LEO) has surged from less than a thousand in 2019, when SpaceX began launching its colossal Starlink broadband constellation, to more than 10,000 today. As other megaconstellations […]

Milan — The European Space Agency has refined its plan for the European Resilience from Space (ERS) program, outlining a €1 billion ($1.15 billion) framework that more directly ties Earth observation, telecommunications and navigation to Europe’s growing defense and security needs. The updated proposal will go before member states for approval at the Nov. 26–27 […]

The Role of Space-Based Interceptors in Golden Dome Webinar

From inflationary pressures and shifting interest rates to supply chain challenges and intensifying great-power competition, today’s macroeconomic and geopolitical forces are reshaping the future of space investment. For investors and businesses, navigating this environment means balancing capital market dynamics, technology cycles, and an increasingly complex landscape of export controls, trade restrictions, and government influence.

In space policy today, Republican views dominate. The party holds majorities in the House and Senate, while the White House is stretching — or breaking — the limits of executive power. Democratic views on space are largely couched in terms of opposition to White House initiatives, such as proposed cuts in NASA’s budget or efforts […]

Biomass launch

London — Warsaw Increasing tensions with Russia have prompted defense spending boosts throughout Europe that will benefit fledgling smallsat launcher companies across the continent.  But Europe is still years away from meeting its own space access needs, analysts said.  The progress of European smallsat launcher developers has been slower than promised, with companies facing technical […]

Why the U.S. shouldn’t simply race to Lagrange points 

4 novembre 2025 à 15:00
Vigil

From the first satellite in orbit, to the first human in space, to the first steps on the moon, the United States government has always framed space exploration as a race. As U.S.-China space competition intensifies, so too does our American instinct to reach the next first. The Earth-moon Lagrange points may be next. In […]
