On June 25, astronauts Shane Kimbrough and Thomas Pesquet successfully completed an almost seven-hour EVA (extravehicular activity, or spacewalk) to install solar panels on the International Space Station. What does it take to don a spacesuit and venture out on such a technical and dangerous mission? Surprisingly, one of the main criteria (besides the years of astronaut training) is body size.

NASA's Mars helicopter Ingenuity has begun to scout missions for the Perseverance rover, completing its ninth and most challenging flight yet.
NASA announced the "most challenging flight yet" was a success Monday via Twitter.

A unique study of ancient diamonds has shown that the basic chemical composition of the Earth's atmosphere which makes it suitable for life's explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today's mantle, which in turn indicates that there has been no fundamenta

Scientists from Tohoku University and the University of Maryland have pinpointed the strong magnetic field of the early sun as the reason behind the radial variation of rock and metal in rocky planets' cores. This magnetic field, which pulled small iron grains inward, explains Mercury's big iron core and why Mars has so little iron in its core.
The details of their research were published

Tantalising evidence has been uncovered for a mysterious population of "free-floating" planets, planets that may be alone in deep space, unbound to any host star. The results include four new discoveries that are consistent with planets of similar masses to Earth, published in Monthly Notices of the Royal Astronomical Society.
The study, led by Iain McDonald of the University of Manchester

The heart of the Exospheric Mass Spectrometer (EMS) is visible in this image of the key sensor that will study the abundance of lunar water and water ice for upcoming missions to the Moon.
This spectrometer is being delivered to NASA today as part of the PITMS instrument for its launch to the Moon later this year.
EMS is based on an ‘ion trap’, an ingenious detector device that allows researchers to identify and quantify sample atoms and molecules in a gas and allows to establish a corresponding mass spectrum. Scientists at The Open University and RAL Space are developing EMS
