Space Operations
NASA selected the Dynamic Atmosphere-Ionosphere Explorer, or DAPHNE, to move into development as a heliophysics mission targeting launch no earlier than 2029. SpaceNews reports the mission will fly two identical satellites carrying three instruments to measure composition, temperature and winds in the thermosphere while studying how space weather and Earth’s lower atmosphere interact. The project advances a long-standing decadal-survey priority and is designed to close a gap in understanding how solar activity and atmospheric dynamics affect each other.

SCIENCE
A Tsinghua University-led student team is developing the START smallsat to observe asteroid Apophis during its unusually close 2029 pass by Earth. The spacecraft is slated to launch in 2028 on a Landspace Zhuque-3 rideshare and then use solar electric propulsion to climb into position for the encounter. The mission adds China to a growing international effort to collect science and planetary-defense data during one of the decade’s most closely watched asteroid events.

TECH
Boeing says it completed high-fidelity entanglement-swapping tests for its Q4S quantum networking payload ahead of a planned on-orbit demonstration in 2027. The company framed the result as proof that a core quantum-networking function can work on mission-ready hardware rather than only in laboratory setups. The milestone reflects broader interest in space-based quantum communications and timing systems with potential security and resilience applications.

DIPLOMACY
Technical talks on a broader U.S.-Iran nuclear and sanctions-relief deal were delayed Thursday, giving the diplomatic push an early setback. The Hill reports the White House said the logistics have been difficult and unpredictable, while overnight fighting in Lebanon further complicated the environment around the talks. The delay raises questions about whether the administration can turn its 60-day memorandum of understanding into a more durable agreement.

MIDEAST
Renewed fighting between Israel and Hezbollah is testing the preliminary U.S.-Iran arrangement meant to open nuclear talks and prevent a wider war. According to The Hill, Iran has made a Lebanon ceasefire a priority condition for continuing discussions with Washington, and the latest violence contributed to postponing planned talks. The story highlights how quickly regional security events can spill into U.S. diplomacy and complicate a fragile negotiating track.

M&A
Private-equity firm EQT plans to acquire Berlin-based Exolaunch, a rideshare integrator that has managed more than 790 satellites across 47 missions. SpaceNews says the deal is expected to close in the fourth quarter of 2026 and would give Exolaunch additional backing as demand for launch integration and deployment hardware grows. The transaction is a notable consolidation move in the smallsat launch-services ecosystem.

FUNDING
Gate Space secured 6.3 million euros in public-backed funding to accelerate industrialization of its chemical propulsion technology. SpaceNews reports the hardware is slated to fly in February on BeaconSat, described as Austria’s first military satellite. The award underscores how European governments are channeling capital toward domestic space suppliers tied to sovereignty and defense priorities.

DEFENSE
U.S. Central Command said the United States has lifted the naval blockade of Iranian ports and coastlines after Washington and Tehran signed a 60-day memorandum of understanding. USNI News reports U.S. naval forces will remain in the region to enforce the agreement, while maritime security guidance lowered the threat level in the Strait of Hormuz from critical to moderate. The move marks a significant operational shift in the Gulf while negotiators continue working on Iran’s nuclear file.
