Thawing Permafrost Could Leach Microbes, Chemicals Into Environment

Scientists are turning to a combination of data collected from the air, land, and space to get a more complete picture of how climate change is affecting the planet’s frozen regions.

PASADENA, Calif. (NASA PR) — Trapped within Earth’s permafrost – ground that remains frozen for a minimum of two years – are untold quantities of greenhouse gases, microbes, and chemicals, including the now-banned pesticide DDT. As the planet warms, permafrost is thawing at an increasing rate, and scientists face a host of uncertainties when trying to determine the potential effects of the thaw.

Teledyne Imaging’s Infrared Sensors Launched Aboard the James Webb Space Telescope

For the last time on Earth, the James Webb Space Telescope’s sunshield was deployed and tensioned by testing teams at Northrop Grumman in Redondo Beach, California where final deployment tests were completed. Webb’s sunshield is designed to protect the telescope from light and heat emitted from the sun, Earth, and moon, and the observatory itself. (Credit: NASA/Chris Gunn)

Teledyne’s infrared detectors are the “eyes” of the world’s most advanced space telescope

THOUSAND OAKS, Calif. (Teledyne Technologies PR) — Teledyne Technologies Incorporated (NYSE:TDY) congratulates NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA) on the successful launch of the James Webb Space Telescope (JWST). Teledyne provided 15 extremely sensitive H2RG infrared detectors that are used in three of the four science instruments of JWST: the Near-Infrared Camera (NIRCam), the Fine Guidance Sensor (FGS), and the Near-Infrared Spectrograph (NIRSpec). Ten Teledyne detectors in NIRCam will study the structure and morphology of the universe. Three Teledyne detectors in FGS will be used to point and stabilize the telescope. Two Teledyne detectors in NIRSpec will reveal information about chemical composition, temperature, and velocity of what JWST observes. Teledyne also provided the SIDECAR ASIC focal plane electronics that operate the H2RG detectors.

PARIS, November 13, 2020 (ESA PR) — Today, ESA signed contracts with Thales Alenia Space in France and in Italy, and Airbus in Spain to build three of the new high-priority Copernicus satellite missions: CHIME, CIMR and LSTM, respectively.

Each mission is set to help address different major environmental challenges such as sustainable agriculture management, food security, the monitoring of polar ice supporting the EU Integrated Policy for the Arctic, and all will be used to understand climate change.

ESA Awards OHB Contracts for Copernicus Missions

BREMEN, Germany (OHB System PR) — OHB System AG, a subsidiary of Bremen-based space and technology group OHB SE (Prime Standard, ISIN DE0005936124), has been selected by the European Space Agency ESA as the prime contractor for the CO2M mission (CO2 Monitoring Mission in the Copernicus program).

This mission includes the Copernicus satellites, which will measure global anthropogenic CO2 emissions and thus play a key role in studying the causes of climate change and monitoring it.

OHB System and OHB Italia will also be responsible for the payload on two further missions (CHIME: Copernicus Hyperspectral Imaging Mission for the Environment and CIMR: Copernicus Imaging Microwave Radiometer) as subcontractors of Thales Alenia Space.

The order volume resulting from today’s bid decisions is expected to be more than EUR 800 million [$900 million]. Final contract negotiations will start shortly and contract signings are expected in the coming weeks.

Copernicus is a satellite Earth observation program of the European Commission and the European Space Agency ESA. It provides Earth observation data for environmental protection, climate monitoring, natural disaster assessment and other social tasks.

In addition, ESA’s Industrial Policy Committee (IPC) has approved OHB System’s proposal for the HERA asteroid defense mission for final negotiations. Implementation of the HERA mission has already commenced. The contract is expected to be worth around EUR 130 million [$146 million].

Six New Missions for the European Copernicus Earth Observation Program

  • On 1 July 2020, the European Space Agency awarded contracts for the development and construction of six further Copernicus satellites.
  • Contracts with a value of more than 800 million euro are being awarded to space companies in Germany, a high percentage of which are SMEs.
  • The new satellites are intended to help find answers to the global challenges posed by climate change, population growth and environmental problems.

BONN, Germany (DLR PR) — Sentinel satellites are at the heart of Copernicus, Europe’s largest Earth observation programme. Sentinels are already reliably and continuously providing large amounts of data on the state of the climate, vegetation and oceans. Now, six more ‘Earth Guardians’, the High Priority Candidate Missions (HPCM), are being added.
