ESA - CRISTAL updates
« on: 09/23/2020 07:07 pm »
Airbus selected for ESA’s new polar ice and snow topography mission

Quote
The European Space Agency (ESA) has selected Airbus to develop and build the Copernicus polar ice and snow topography mission (CRISTAL). With two satellites the CRISTAL mission will ensure the long-term continuation of radar altimetry ice elevation and change records. It is one of six new missions to expand the current capabilities of the Copernicus space component for the benefit of all European citizens. The contract is worth € 300 million.

With launch planned in 2027, CRISTAL will carry an advanced multi-frequency altimeter that will measure sea ice thickness and ice sheet elevations. These data will support maritime operations in polar oceans and contribute to a better understanding of climate processes. CRISTAL will also support applications related to coastal and inland waters and the observation of ocean topography.

Plans underway for new polar ice and snow topography mission

The mission will ensure the long-term continuation of radar altimetry ice elevation and topographic change records, following on from previous missions such as ESA’s Earth Explorer CryoSat mission and other heritage missions.

The contract for CRISTAL is the second out of the six new high-priority candidate missions to be signed – after the Copernicus Carbon Dioxide Monitoring mission (CO2M) in late-July. The CRISTAL mission is part of the expansion of the Copernicus Space Component programme of ESA, in partnership with the European Commission.

The European Copernicus flagship programme provides Earth observation and in situ data, as well as a broad range of services for environmental monitoring and protection, climate monitoring and natural disaster assessment to improve the quality of life of European citizens.

Yep, Thales Alenia Space is the subcontractor for the dual-frequency (Ku/Ka) radar interferometer altimeter payload IRIS. Cryosat-derived design for the satellite, IRIS is the successor for Cryosat's SIRAL:

Polar Ice and Snow monitoring mission CRISTAL on track [dated May 24]

Quote from: Airbus
The Copernicus Polar Ice and Snow Topography Altimetry mission CRISTAL is clearly on track. Following an intensive review process the European Space Agency ESA has confirmed that the preliminary design of the satellite meets all system requirements.

<snip>

The Preliminary Design Review (PDR) was organised using a new more collaborative format. As a first step an extensive review by over 60 ESA engineers of a comprehensive data package, established by more than 100 engineers led by Airbus took place over four weeks. In a second step the major findings were intensively discussed in an interactive way between senior level experts both on ESA and Industry side up to the successful completion of the review.

<snip>

Following the successful PDR the CRISTAL project is now on track for the Critical Design Review (CDR) scheduled for May 2024. The satellite platform and instrument will then be integrated and tested in the new, highly digitalised integration centre at Airbus in Friedrichshafen. CRISTAL is currently scheduled for launch from the European spaceport in Kourou in 2027.
