Quick answer · as of 27 Jul 2026

Juno's findings on Io's subsurface and Soyuz MS-28's return dominate today's space news, alongside close orbital encounters.

NASA's Juno spacecraft has provided new insights into the volcanic moon Io, revealing unexpected subsurface temperatures and a remarkably smooth surface. These findings, published by NASASpaceflight, suggest that Io's heat distribution and geological activity are more complex than previously understood. Juno, in orbit around Jupiter since 2016, continues to supply valuable data on the gas giant and its moons. For more on Juno's mission, visit our Spacecraft & Capsules section.

The Soyuz MS-28 spacecraft has returned to Earth after an eight-month mission aboard the International Space Station (ISS). NASA astronaut Chris Williams and his crewmates landed safely, marking the end of their extended stay in orbit. The mission's conclusion coincides with ongoing discussions in space policy, as highlighted by SpacePolicyOnline, regarding international collaboration and crew rotations. Details of the mission can be explored through our Launch Log.

Orbital Close Encounters

Recent data indicates several close approaches between active satellites and debris, including a minimum distance of 1.21 km between ION SCV-023 and OBJECT BE. Such events underline the growing concerns over space debris and the need for effective tracking systems. Our Debris Map provides real-time tracking of these objects, helping to mitigate collision risks.

What to Watch

While there are no launches scheduled for the immediate future, the space policy discussions from July 26 to August 1, 2026, are worth following. These discussions could influence future international space missions and collaborations. Keep an eye on our Launch Schedule for updates on upcoming launches.
