Video: 00:02:01 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 radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.
Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
In our modern wireless world, almost all radio frequency (RF) spectrum bands are shared among multiple users. In some domains, similar users technically coordinate to avoid interference. The spectrum management team, part of NASA’s SCaN (Space Communications and Navigation) Program, represents the collaborative efforts across U.S. agencies and the international community to protect and enable NASA’s current and future spectrum-dependent science, exploration, and innovation.
Coordination with Other Spectrum Stakeholders
NASA works to promote the collaborative use of the RF spectrum around Earth, and beyond. For example, NASA coordinates closely with other U.S. government agencies, international civil space agencies, and the private sector to ensure missions that overlap in time, location, and frequency do not cause or receive interference that could jeopardize their success. The spectrum management team protects NASA’s various uses of the spectrum by collaborating with U.S. and international spectrum users on technical matters that inform regulatory discussions.
As a founding member of the Space Frequency Coordination Group, NASA works with members of governmental space- and science-focused agencies from more than 35 countries. The Space Frequency Coordination Group annual meetings provide a forum for multilateral discussion and consideration of international spectrum regulatory issues related to Earth, lunar, and deep space research and exploration. The Space Frequency Coordination Group also provides a forum for the exchange of technical information to facilitate coordination for specific missions and enable efficient use of limited spectrum resources in space.
Domestic and International Spectrum Regulators
Creating and maintaining the global spectrum regulations that govern spectrum sharing requires collaboration and negotiation among all its diverse users. The International Telecommunication Union manages the global spectrum regulatory framework to optimize the increasing, diverse uses of the RF spectrum and reduce the likelihood of RF systems experiencing interference. U.S. regulators at the National Telecommunications and Information Administration and the Federal Communications Commission are responsible for developing and administering domestic spectrum regulations. Organizations across the world cooperatively plan and regulate spectrum use. The spectrum management team participates on behalf of NASA at both national and international levels to ensure that the U.S. domestic and international spectrum regulatory framework supports and enables NASA’s current and future missions.
NASA collaborates with domestic and international spectrum stakeholders to provide technical expertise on space spectrum topics to ensure regulations continue to enable space exploration, science, and innovation.NASA Share

The European Space Agency has joined the world space community in congratulating the African Space Agency on its official inauguration. The African Space Agency (AfSA) is the second regional space agency after ESA and has been in development since 2015, with the African Union Commission adopting an African space policy and strategy in 2016.

From 7 to 11 April, ESA's Centre for Earth Observation in Frascati, ESRIN, hosted the 2025 edition of ESA School Days, welcoming almost 1400 young students.
The event kicked off with primary school students (4th and 5th grades) visiting during the first three days, followed by secondary school students on the final two days.
Throughout the week, 35 schools from across Italy engaged in presentations and laboratories, delving into the diverse space activities conducted at ESA’s establishment.
This initiative, which included contributions from ESERO Italia and the Italian Space Agency (ASI), aims to inspire and engage the next generation of STEM students by sharing knowledge about space and the European Space Agency.
