| ## This Week in Space & Science Astronomers achieved a milestone this week with the James Webb Space Telescope's first direct examination of an exoplanet surface, revealing a dark, hot rocky world rather than just atmospheric data. This breakthrough opens new avenues for understanding planetary formation and composition beyond our solar system. Meanwhile, the discovery of 27 candidate planets orbiting binary stars highlights how complex gravitational environments can still support planetary systems, advancing models of planet formation in multi-star setups. International collaboration strengthened with ESA and JAXA formalizing the Ramses mission to study asteroid Apophis ahead of its 2029 close approach to Earth. NASA and SpaceX prepared another cargo resupply to the International Space Station, while a simulated Mars habitat mission reached the 200-day mark, testing long-duration isolation protocols. These developments underscore ongoing efforts to expand human presence and robotic exploration in space.

The world appears as a dark, hot rock, providing concrete data on an exoplanet exterior instead of just atmosphere or orbit. This shifts exoplanet science from indirect inferences to direct surface characterization. **27 Candidate Planets Found Orbiting Binary Stars.** Researchers identified 27 potential planets that orbit pairs of stars in distant systems. These findings illuminate how planets can form and persist amid the complex gravitational interactions of binary stars. The candidates expand our view of possible planetary architectures. **ESA and JAXA Formalize Ramses Mission to Apophis.** The agencies signed an agreement for a joint mission to rendezvous with asteroid Apophis before its 2029 Earth flyby. The effort bolsters planetary defense coordination and data sharing. It will gather critical information on the asteroid's structure and trajectory. **Firefly Plans Alpha Block 2 Rocket Debut.** Firefly Aerospace will launch the upgraded Alpha Block 2 late this summer amid strong demand for national security payloads. The vehicle improvements support faster turnaround and higher performance. This reflects growing commercial launch competition. **Lunar Outpost Raises $30 Million for Rover Redesign.** The company secured funding to update its rovers for revised NASA Artemis landing plans. Resources will go toward hardware revisions and testing. The move aligns private lunar efforts with government timelines.

A Dragon spacecraft is scheduled for an upcoming resupply mission carrying food, experiments, and spares. The simulated Mars habitat crew has now logged 200 days of isolation, validating resource recycling systems. MDA Space advances development of a robotic arm for the Lunar Gateway, with the Canadian Space Agency reviewing the next phase.

By capturing and modeling reflected and emitted light across infrared wavelengths, researchers distinguished surface composition from atmospheric effects, confirming a dark, thermally dominated exterior. This approach bypasses previous limitations where only transmission spectra were available. Implications include refined habitability assessments and better constraints on formation theories for terrestrial worlds. Follow-up observations could map surface features on similar targets.

Comet 10P/Tempel 2 glows around magnitude 15 in Aquila and is accessible to larger telescopes as it rises later each night. Asteroid 13 Egeria crosses Virgo, providing a clear target for tracking its motion over hours against background stars.

A SpaceX Dragon cargo mission to the ISS is in final preparations. Rocket Lab's Pegasus XL launch carrying the Katalyst Link servicing vehicle is set for June. Watch for further Artemis-related hardware tests and potential national security rideshares. |
