NASA has postponed the return of astronauts Butch Wilmore and Sunita Williams to the International Space Station (ISS) due to safety concerns over Boeing’s Starliner aircraft. The mission, originally planned for September 2024, has been postponed to February 2025.
The European Space Agency’s JUICE mission successfully completed the world’s first lunar-Earth flyby on August 20, 2024, a vital maneuver that used the gravitational forces of the Moon and Earth to send the spacecraft toward Venus. This accomplishment is critical for saving fuel and modifying the spacecraft’s trajectory as it travels to Jupiter.
The upper stage of a Chinese Long March 6A rocket fragmented into over 700 pieces in low Earth orbit following its launch on August 6, 2024, as confirmed by U.S. Space Command on August 8, posing a significant threat to orbital safety.
Researchers from the Massachusetts Institute of Technology (MIT) investigated the significant impacts and scientific insights from the May 2024 G5 – Extreme geomagnetic storm and how it impacted satellite operations and atmospheric activities.
Russian decommissioned satellite Resurs-P1 broke up in orbit on June 26, 2024, releasing roughly 100 pieces of trackable debris. The number rose to 180 by the end of June 27 and is expected to keep rising, according to Leo Labs. Following the breakup, NASA instructed the 9 astronauts aboard the International Space Station (ISS) to take shelter in their respective spacecraft as a standard precautionary measure.
The Geostationary Operational Environmental Satellite-U (GOES-U) was successfully launched on June 25, 2024, from NASA’s Kennedy Space Center. This marks the completion of the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) program, led by the University of Colorado Boulder’s LASP, enhancing space weather monitoring.
In March 2021, NASA ground controllers deployed the International Space Station’s (ISS) robotic arm to discard a cargo pallet (EP-9) containing obsolete nickel hydride batteries, following upgrades to lithium-ion units. This operation set a record for the heaviest item jettisoned from the ISS. While the entire pallet was expected to disintegrate before reaching Earth’s surface, a fragment of this hardware survived atmospheric re-entry and struck a residence in Naples, Florida, in March 2024.
The European Space Agency’s SMOS and Swarm satellites have, for the first time, successfully tracked a severe solar storm, following an X1.1 solar flare and a halo coronal mass ejection (CME) on March 23, 2024. The CME impacted Earth on March 24, producing a G4 – Severe geomagnetic storm — the strongest geomagnetic storm since September 2017.
Launched in 2013, the European Space Agency’s (ESA) Swarm mission, consisting of three satellites, has provided a decade of invaluable data on Earth’s magnetic field and core dynamics. This data has enabled significant advances in understanding the mechanisms behind the magnetic field’s slow changes, as detailed in a recent ESA-funded project report.
On September 26, 2022, NASA’s Double Asteroid Redirection Test (DART) mission made history by intentionally colliding with the asteroid Dimorphos, significantly altering both its orbital period and physical shape. This is the first time humanity has purposefully altered the motion of a celestial object, as well as the first full-scale demonstration of asteroid deflection technology.
