An Astronaut's View from Space
NASA Image Of The Day
NASA astronaut Reid Wiseman tweeted this photo from the International Space Station on Tuesday morning, Sept. 2, 2014. "My favorite views from #space ? just past #sunrise over the ocean," the Expedition 40 astronaut tweeted. The Expedition 40 crew has been busy aboard the Space Station, recently performing health checks and humanoid robot upgrades. In the meantime, a trio of orbital residents is packing up gear as they prepare to return home in less than two weeks. Commander Steve Swanson powered down and stowed Robonaut 2 after wrapping up its mobility upgrades this week. He installed new legs on the humanoid robot including external and internal gear as well as cables. This sets the stage for more upgrades in the fall before Robonaut takes its first steps as an assistant crew member. Robonaut was designed to enhance crew productivity and safety while also aiding people on Earth with physical disabilities. Image Credit: NASA/Reid Wiseman (@astro_reid)...

  • Radar vision maps Napa Valley earthquake

    Sentinel-1A has added yet another string to its bow. Radar images from this fledgling satellite have been used to map the rupture caused by the biggest earthquake that has shaken northern California in 25 years.



  • A wing for Sentinel-2A

    Imaging Earth’s land with unprecedented speed and resolution has come another step closer as the next Sentinel satellite has been given its solar wing and started a strenuous six-month test campaign to make sure that it is fit for launch next April.



  • Sentinel-1 poised to monitor motion

    Although it was only launched a few months ago and is still being commissioned, the new Sentinel-1A radar satellite has already shown that it can be used to generate 3D models of Earth’s surface and will be able to closely monitor land and ice surface deformation.



  • Ice sheet highs, lows and loss

    Measurements from ESA’s CryoSat mission have been used to map the height of the huge ice sheets that blanket Greenland and Antarctica and show how they are changing. New results reveal combined ice volume loss at an unprecedented rate of 500 cubic kilometres a year.



  • Summer school success

    Young Earth scientists from all over the world have wrapped up their two-week course at ESA’s ESRIN centre for Earth observation in Frascati, Italy.



  • Monitoring volcanoes

    Radar satellites, like Sentinel-1A, can detect ground movements down to the millimetre, helping us to understand the processes happening below Earth’s surface

  • Sea of sand

    Earth observation image of the week: the expansive Rub’ al Khali desert on the southern Arabian Peninsula, also featured on the Earth from Space video programme

  • Costa Concordia tow

    Sentinel-1A captured this radar image of the Costa Concordia cruise ship as it was being towed toward Genoa at the weekend

  • Lifetime of gravity measurements heralds new beginning

    Although ESA’s GOCE satellite is no more, all of the measurements it gathered during its life skirting the fringes of our atmosphere, including the very last as it drifted slowly back to Earth, have been drawn together to offer new opportunities for science.



  • Magnetic field update

    The Swarm satellites have mapped changes in Earth’s magnetic field over the last six months. Discover more about our planet’s ever-changing protective shield

  • 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?
