James Webb Space Telescope's Heart Survives Deep Freeze Test
NASA Image Of The Day
After 116 days of being subjected to extremely frigid temperatures like that in space, the heart of the James Webb Space Telescope, the Integrated Science Instrument Module (ISIM) and its sensitive instruments, emerged unscathed from the thermal vacuum chamber at NASA?s Goddard Space Flight Center in Greenbelt, Maryland. The Webb telescope's images will reveal the first galaxies forming 13.5 billion years ago. The telescope will also pierce through interstellar dust clouds to capture stars and planets forming in our own galaxy. At the telescope's final destination in space, one million miles away from Earth, it will operate at incredibly cold temperatures of -387 degrees Fahrenheit, or 40 degrees Kelvin. This is 260 degrees Fahrenheit colder than any place on the Earth?s surface has ever been. To create temperatures that cold on Earth, the team uses the massive thermal vacuum chamber at Goddard called the Space Environment Simulator, or SES, that duplicates the vacuum and extreme temperatures of space. This 40-foot-tall, 27-foot-diameter cylindrical chamber eliminates the tiniest trace of air with vacuum pumps and uses liquid nitrogen and even colder liquid helium to drop the temperature simulating the space environment. The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built. Webb is an international project led by NASA with its partners, the European Space Agency and the Canadian Space Agency. > More: NASA Webb's Heart Survives Deep Freeze Test Image Credit: NASA/Chris Gunn...

  • Copernicus Sentinel-1: making our seas safer

    Within the first days of its operational life, the Sentinel-1A satellite has provided data for marine services in the Arctic.



  • Monitoring epidemics

    Satellite data can help identify areas prone to the emergence and spread of epidemics such as Ebola, malaria, meningitis or dengue fever

  • Europe secures new generation of weather satellites

    Contracts were signed today to build three pairs of MetOp Second Generation satellites, ensuring the continuity of essential information for global weather forecasting and climate monitoring for decades to come.



  • High desert

    Earth observation image of the week: a Sentinel-1A image over the ‘high desert region’ of the northwestern United States, also featured on the Earth from Space video programme

  • Fishbone forest

    Technology image of the week: Deforestation in western Brazil, as imaged by ESA’s Proba-V minisatellite

  • Romania to shed new light on the atmosphere

    Romania is leading the way in an ambitious project to build an instrument to detect and monitor tiny particles suspended in the air. The new ‘lidar’– the first of its kind in Europe – is set to contribute to ESA’s satellites that focus on the atmosphere.



  • Dragon receives high award in China

    Following a decade of cooperation, China has honoured ESA’s Yves-Louis Desnos with the People’s Republic of China Friendship Award – the country’s highest honour for foreign experts who have contributed to China’s economic and social progress.



  • My Planet from Space

    The fragility and beauty of our planet came into focus yesterday with a special viewing of satellite images at Rome’s Palazzo delle Esposizioni. The event was attended by the heads of ESA, NASA, Italy’s space agency and representatives from the Italian Presidency of the Council of the EU.



  • My Planet from Space

    Discover the beauty and fragility of our planet in a special exhibition at the Palazzo delle Esposizioni in Rome, Italy

  • First Copernicus satellite now operational

    With the commissioning of Sentinel-1A completed and the satellite’s transfer to the team in charge of its exploitation, its data are available as of today to all users.

    This marks the beginning of the satellite’s operational life, delivering radar coverage for an array of applications in the areas of oceans, ice, changing land and emergency response.



  • Earth’s portrait

    The latest land-cover map for studying the effects of climate change, conserving biodiversity and managing natural resources has been released

  • Where is it?

    Some of the most familiar places can be difficult to recognise from a satellite’s point of view – can you place these images on a map?
