Curveball Mystery: Rocket Lab's Secret Suborbital Mission Ends Up in Orbit

Rocket Lab's HASTE suborbital vehicle launched on the Curveball mission for a U.S. defense program on November 18, 2025. A few days later, the U.S. Space Force tracked the rocket in what appears to be a 120-mile orbit with a 40-degree inclination, but payload data remain undisclosed and it’s unclear whether the flight was intentionally aimed at orbit or ended up there by miscalculation, prompting questions about the mission’s outcome.

Sixteen Sunrises in a 90-Minute Orbit: How the ISS Keeps Time in Space

The ISS orbits Earth roughly every 92 minutes at about 28,000 km/h, completing around 15–16 orbits per day. From the cupola, crew see about sixteen sunrises and sunsets daily, but that cycle is a window view, not a crew day; onboard time runs on UTC and is supported by LED lighting to align sleep and wakefulness. During high-beta-angle periods the station can stay in sunlight for days, so the “sixteen sunrises” figure is an average, not a constant.

New Glenn Grounded After Satellite Misses Target Orbit

Blue Origin’s New Glenn rocket launched a satellite, but it ended up in the wrong orbit, prompting officials to ground the mission at Cape Canaveral while they review what went wrong.

Milankovitch cycles reveal where ancient shale oil formed

Researchers link Milankovitch orbital cycles to the formation of shale oil in the Sichuan Basin, showing that wetter periods during high orbital eccentricity produced organic-rich lake muds that later became shale reservoirs. By combining crust/mantle data, rock cores, and Jurassic lake-mud gamma-ray records, they align sediment layers with orbital timing to better predict where high-quality shale oil formed. The study, published Sept. 30, 2025, notes shale oil’s extraction via fracking and related environmental concerns, but the method could improve exploration targeting.

NASA Mars Orbiter Possibly Out of Commission

NASA's MAVEN spacecraft orbiting Mars has been unresponsive since December 6, with recent data suggesting it was spinning unexpectedly, and efforts to re-establish contact are ongoing, but prospects seem uncertain as the spacecraft has been operational for over a decade studying Mars' atmosphere.

NASA's Mars and Interstellar Missions Face Communication Blackouts During Solar Conjunction

NASA's MAVEN spacecraft orbiting Mars has been unresponsive since December 6, with efforts to re-establish contact ongoing. The spacecraft, which has been studying Mars' atmosphere for over a decade, appears to have experienced an unexpected spin, and communication attempts are delayed until mid-January due to planetary alignment. The mission's status remains uncertain, raising concerns about its future.

SpaceX Starts Lowering Orbits of 4,400 Starlink Satellites for Safety

SpaceX plans to lower the orbits of approximately 4,400 Starlink satellites from 550 km to 480 km in 2026 to enhance safety and reduce collision risks, especially as solar activity decreases and atmospheric drag lessens, impacting satellite decay times and space debris management.

Earth's Closest Approach to the Sun and Its Seasonal Effects

Earth is closest to the Sun at perihelion in January, but it’s winter in the Northern Hemisphere because the planet’s axial tilt causes seasonal changes, not its distance from the Sun. The tilt results in varying sunlight exposure, creating summer and winter, while the elliptical orbit’s slight distance variation has minimal impact on temperatures.

Earth's Perihelion and Its Impact on Seasons and Sun Observations

Earth's closest approach to the Sun, called perihelion, occurs during winter in the Northern Hemisphere due to the Earth's axial tilt and elliptical orbit, which causes seasonal variations in sunlight exposure. This timing is a coincidence and varies over thousands of years due to gravitational influences and orbital changes.

NASA's MAVEN Mars Probe Remains Silent Amid Orbit and Spin Changes

NASA is attempting to reestablish contact with the MAVEN Mars orbiter after it lost response, with indications that it may be tumbling and off its expected trajectory, complicating recovery efforts especially with upcoming solar conjunction blocking communication. The spacecraft's status remains uncertain, and its potential loss could reduce NASA's active Mars orbiters to two aging spacecraft.

Mystery Object C/2025 V1 Borisov Sparks Interstellar Inquiry

A new object, C/2025 V1, discovered by Gennady Borisov, is likely a natural object from the Oort cloud and not related to the interstellar object 3I/ATLAS, based on its orbit and non-gravitational acceleration. The article discusses the potential for distinguishing natural from technological origins of such objects through spectroscopic analysis during their close approach to Earth in December 2025.

SpaceX Celebrates Milestones with Record-Breaking Starlink Launches

SpaceX has launched its 10,000th Starlink satellite, contributing to a total of over 10,006 satellites, which now make up about two-thirds of all active satellites in orbit. While this has improved global internet access, it raises concerns about space congestion, collision risks, and space debris, as the number of satellites continues to grow rapidly.
