Get ready for an exciting launch event! The future of Earth observation is about to take off.
The European Space Agency (ESA) is set to launch its HydroGNSS mission, a groundbreaking project that will provide crucial insights into our planet's water cycle. But here's where it gets controversial: this mission involves a unique technique that could revolutionize how we understand and monitor our environment.
HydroGNSS: Unlocking the Secrets of Earth's Water Cycle
On November 19th, at 19:18 CET (10:18 Pacific Time), ESA will launch its twin-satellite mission, HydroGNSS, from the Vandenberg Space Force Base with SpaceX's Falcon 9 rocket. This mission aims to gather vital data on four key hydrological parameters: soil moisture, inundation and wetlands, freeze/thaw state, and above-ground biomass. These parameters are closely linked to Essential Climate Variables, which are essential for assessing climate risks and understanding our changing planet.
The live coverage of this historic launch will be available on ESA Web TV, starting at 19:01 CET (10:01 Pacific Time). Don't miss this opportunity to witness the liftoff and be a part of this scientific adventure!
Scouting for Water: A Mission to Protect Our Planet
Changes in the global water cycle pose significant threats to our environment and communities worldwide. HydroGNSS, as part of ESA's FutureEO program, aims to provide critical observations to help mitigate these risks. But how does it work?
HydroGNSS employs a technique called Global Navigation Satellite System (GNSS) reflectometry. This innovative approach utilizes signals from navigation satellites like Galileo and GPS, which continuously transmit low-power L-band microwave navigation signals towards Earth. While these satellites primarily serve global positioning and navigation purposes, their signals can be harnessed for scientific data collection.
When the GNSS signal reflects off Earth's surface, it undergoes alterations influenced by the physical properties of terrain, ice, oceans, or vegetation. By comparing these altered signals with direct signals from the GNSS satellites, HydroGNSS obtains valuable scientific data on the Earth's water cycle.
The mission consists of two microsatellites, each carrying a GNSS reflectometry instrument, orbiting at an altitude of approximately 550 km and positioned 180 degrees apart. This configuration allows for comprehensive coverage and data collection.
Italy's Earth Observation Constellations: IRIDE's Impact
Alongside HydroGNSS, the launch will also see the deployment of satellites for Italy's national mission, IRIDE. IRIDE is designed to provide public sector services based on data from its Earth observation constellations. Specifically, satellites for its second constellation, Eaglet II, will be launched.
Each satellite in the Eaglet II constellation carries advanced instruments, including a multispectral, high-resolution optical instrument and an Automatic Identification System (AIS) instrument. OHB Italia serves as the prime contractor for these satellites.
Eaglet II is the second of six constellations for IRIDE, with the first, Hawk for Earth Observation (HEO), launched earlier this year. Data from IRIDE satellites will support the creation of maps, monitoring services, and multi-temporal analysis, benefiting Italy's public authorities and civil protection department.
Greece's National Small Satellite Program: A Step Towards Innovation
Additionally, the launch will mark a significant milestone for Greece's National Small Satellite Program. Two high-resolution ICEYE radar satellites, the first of their kind, will be launched under this program. This initiative aims to enhance Greece's satellite technology and application capabilities, fostering innovation, job creation, and economic growth.
The project is led by the Hellenic Space Center and the Greek Ministry of Digital Governance, with ESA providing the overarching framework and support for ICEYE in developing both satellites. This collaboration showcases the potential for international cooperation in advancing space technology and its applications.
