The Atomic Clock Ensemble in Space (ACES), ESA’s state-of-the-art timekeeping facility, is now installed on the Columbus laboratory of the International Space Station. This still image, captured by external cameras on the Station, shows ACES after installation. For 25 years, cameras on the Station have documented activities in orbit, providing real-time views of operations like this one – a rare and remarkable perspective from space. 

On 25 April, the Canadian Space Agency’s robotic arm carefully extracted ACES from the SpaceX Dragon trunk and secured it onto the Columbus External Payload Facility, next to ESA’s space storm hunter ASIM

ESA’s state-of-the-art Biomass satellite has launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).

In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the

ESA’s groundbreaking Biomass satellite, designed to provide unprecedented insights into the world’s forests and their crucial role in Earth’s carbon cycle, has been launched. The satellite lifted off aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana, on 29 April at 11:15 CEST (06:15 local time).

A new era of forest monitoring is quite literally taking off, ushering in what scientists are calling the ‘forest space age’. On April 29, ESA will launch its revolutionary Biomass mission, the first satellite to carry a P-band radar into space – technology that is set to transform how we understand forests and the carbon they store. Along with other space agencies’ instruments already in orbit or soon to be launched, there has never been so many ‘eyes in the sky’ focused on forests.

Yet, the work

The China Manned Space Agency (CMSA) has announced a new series of life science investigations to be conducted aboard the Tiangong space station during the Shenzhou XX crewed mission. The program includes novel biological studies involving zebra fish, planarians, and the soil bacterium Streptomyces. For the first time, Chinese researchers will explore how planarians regenerate in space. Kn

A cutting-edge holographic imaging device named ELVIS is now aboard the International Space Station, poised to transform the study of life in space. Officially known as the Extant Life Volumetric Imaging System, ELVIS is designed to deliver advanced three-dimensional views of microorganisms and cells, providing critical insights into how life endures in the harsh conditions beyond Earth.

NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission successfully completed spacecraft commissioning this week, opening its instrument doors to capture "first light," the mission's first images of the Sun's outer atmosphere and the surrounding space. This is the first step in revealing new details of how the solar atmosphere unfolds and streams through the solar system. Now, mi
