  • Microcarb is a science satellite that will trace CO2 sinks and sources on a global scale.
  • The requested performance for this launch planned in 2023 is 190kg on a sun-synchronous orbit at 650km.

EVRY-COURCOURONNES, France, January 18, 2022 (Arianespace PR) — Arianespace has been awarded a launch contract by ESA, on behalf of the European Commission, to launch Microcarb in 2023 on Vega C. Microcarb is a 190kg satellite developed by CNES that will be delivered into a sun-synchronous orbit, 650km above the Earth.


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.


Emission Reductions From Pandemic Had Unexpected Effects on Atmosphere

Earth’s atmosphere reacted in surprising ways to the lowering of emissions during the pandemic, showing how closely climate warming and air pollution are linked.

PASADENA, Calif. (NASA PR) — The COVID-19 pandemic and resulting limitations on travel and other economic sectors by countries around the globe drastically decreased air pollution and greenhouse gas emissions within just a few weeks. That sudden change gave scientists an unprecedented view of results that would take regulations years to achieve.


How Scientists Are Using the International Space Station to Study Earth’s Climate

HOUSTON (NASA PR) — On Earth, we often look toward the sky longing to know what resides in the rest of the universe. Meanwhile, 250 miles above our planet, the  International Space Station is looking back.

Above us, multiple Earth-observing instruments are mounted on the exterior of several of the station’s modules, including a limb full of cameras, boxes, and tools that hangs off the edge of the station’s Japanese Experiment Module (JEM). Earth-observing CubeSats regularly deploy from the station’s airlock. Astronauts take photos of the planet from the orbiting lab’s windows. This outpost even conducts Earth science experiments. All of this work provides insight into the climate of our home and how we might prepare for coming changes.


OCO-3 Ready to Extend NASA’s Study of Carbon

Updated at 12:35 a.m. PDT (3:35 a.m. EDT) on May 10

NASA’s OCO-3 was removed from the Dragon spacecraft and robotically installed on the exterior of the space station’s Japanese Experiment Module-Exposed Facility as of approximately 9 p.m. PDT on May 9 (12 a.m. EDT on May 10). Over the next two days, a functional checkout will be performed and the OCO-3’s Pointing Mirror Assembly (PMA) will be deployed. The PMA and context cameras will then perform an initial survey of OCO-3’s surroundings to make sure nothing unexpected is interfering with its view of Earth.

SpaceX CRS-17 launched Friday, May 3, 11:48 p.m. PDT (Saturday, May 4, 2:48 a.m. EDT).

PASADENA, Calif. (NASA/JPL-Caltech PR) — When the Orbiting Carbon Observatory 3, OCO-3, heads to the International Space Station, it will bring a new view — literally — to studies of Earth’s carbon cycle.

From its perch on the space station, OCO-3 will observe near-global measurements of carbon dioxide on land and sea, from just after sunrise to just before sunset. That makes it far more versatile and powerful than its predecessor, OCO-2.
