This Week in Space: Reusable Rockets, Interstellar Visitors, and the Future of Earth Observation

The past week has seen a torrent of developments across the space sector, from Europe’s push toward reusable launchers and the detection of a new interstellar object, to the sobering loss of a major climate-monitoring satellite. As the world’s eyes turn skyward, the interplay of innovation, geopolitics, and environmental stewardship is more evident than ever. Here’s an exhaustive look at the latest headlines shaping the future of space.

Europe’s Leap Toward Reusable Rockets: Themis Arrives at Esrange

Europe has long trailed the United States and China in the race for reusable launch vehicles, but the arrival of the Themis demonstrator at Sweden’s Esrange Space Center marks a pivotal milestone. Developed by ArianeGroup under the European Space Agency’s (ESA) reusability roadmap, Themis is Europe’s first full-scale reusable rocket stage demonstrator. Its journey—spanning 3,000 kilometers—culminates in a series of integration and hop-tests, supported by the EU’s SALTO project.

“The arrival of the Themis at Esrange marks an important milestone for this project.”
— Ulrika Unell, SSC

What’s Next for Themis?

Integration and Wet Dress Rehearsal: The stage will be assembled and undergo full systems checks.
Hop Tests: Scheduled to begin in late 2025, these short vertical flights will validate landing, guidance, and reusability technologies.
Strategic Impact: Themis is a critical step for Europe to compete in the global launch market, reduce costs, and foster technological sovereignty.

The Interstellar Frontier: 3I/ATLAS and the Search for Planet Nine

3I/ATLAS: A New Interstellar Visitor

Astronomers have confirmed the detection of 3I/ATLAS (C/2025 N1), only the third known interstellar object to pass through our solar system. Traveling at a blistering 60 km/s and exhibiting cometary activity, 3I/ATLAS is a rare opportunity to study material from beyond our Sun’s domain.

“If confirmed, it will be the third known interstellar object… providing more evidence that such interstellar wanderers are relatively common in our galaxy.”
— Dr. Mark Norris

Trajectory: Its hyperbolic path confirms an origin outside the solar system.
Observability: It will be visible until September 2025 before passing behind the Sun.
Scientific Value: Offers direct insight into the composition and behavior of extrasolar material.

The Elusive Planet Nine

In parallel, astronomers analyzing data from the IRAS and AKARI satellites have identified a possible candidate for the long-hypothesized Planet Nine beyond Neptune. While skepticism remains due to the object’s unusual orbit, the upcoming Vera C. Rubin Observatory may soon provide definitive evidence.

Potential Impact: Confirmation would reshape our understanding of the solar system’s architecture.
Skepticism: The orbit and characteristics remain contentious among planetary scientists.

MethaneSAT: A Climate Monitoring Setback

The Loss of a Pioneering Satellite

The MethaneSAT satellite, a $100 million mission launched in March 2024 to track global methane emissions, has suffered a catastrophic power failure and is “likely not recoverable.” Funded by the Environmental Defense Fund (EDF), Bezos Earth Fund, and Google, MethaneSAT filled a unique observational niche, providing advanced spectrometer data on greenhouse gas emissions.

“The satellite has lost power, and it is likely not recoverable.”
— Environmental Defense Fund

Mission Achievements: Demonstrated direct, high-resolution methane measurement from space; revealed unexpectedly high emissions from oil and gas sites.
Setback: The loss is significant for climate transparency and monitoring, as MethaneSAT’s data was crucial for policy and mitigation efforts.
Next Steps: EDF is considering a replacement satellite, and all data collected to date will be processed and released.
