On 26 March and enduring temperatures of some 500 degrees Celsius from within the orbit of planet Mercury, Solar Orbiter returned spectacular imagery of the Sun during its first close encounter with our home star. Detailed new movies show activity in the solar atmosphere and reveal a variety of features, including something scientists are nicknaming ‘the hedgehog’ with spikes of hot gas reaching out in all directions. 

Solar Orbiter’s ten science instruments are now all working together for the first time. Some are looking at the Sun while others are simultaneously measuring the environment around the spacecraft, enabling

Powerful flares, breathtaking views across the solar poles, and a curious solar ‘hedgehog’ are amongst the haul of spectacular images, movies and data returned by Solar Orbiter from its first close approach to the Sun. Although the analysis of the new dataset has only just started, it is already clear that the ESA-led mission is providing the most extraordinary insights into the Sun’s magnetic behaviour and the way this shapes space weather.

Mitsubishi Electric Corporation (TOKYO: 6503) reports that the company has developed an on-orbit additive-manufacturing technology that uses photosensitive resin and solar ultraviolet light for the 3D printing of satellite antennas in the vacuum of outer space. The novel technology makes use of a newly developed liquid resin that was custom formulated for stability in vacuum. The resin ena

When Artemis I is ready to launch, a range of personnel from NASA, industry, and several international partners will be poised to support the mission. Before they get to launch day, the alignment of the Earth and Moon will determine when the Space Launch System (SLS) rocket with the uncrewed Orion spacecraft atop it can launch, along with several criteria for rocket and spacecraft performance.

With Arctic aviation and maritime activity on the rise, Europe and Canada are taking the lead in developing weather satellites to gather global data and improve observation of Earth’s northernmost latitudes.

The post Proposed constellations would enhance Arctic weather observations appeared first on SpaceNews.

A team of scientists, including Dr. German Martinez from the Universities Space Research Association at LPI, just published a study in the Proceedings of the National Academy of Sciences. This study indicates there are seasonal energy imbalances in the amount of solar energy absorbed and released by Mars which is a likely cause of dust storms, and could play an important role in understanding th
