    To the Arctic for CryoSat and beyond

    After the relative quiet of the long dark winter months, the Arctic will be a tad busier over the coming weeks as numerous researchers descend on this harsh, yet fragile environment. Their aim is not to disturb its beauty, but to join forces in an all-out effort to measure ice on land and sea.

    CubeSats: from educational tools to autonomous space drones

    Roger Walker, Technology CubeSat manager

    CubeSats started as a tool for education. Profs Jordi Puig-Suari of California Polytechnic State University and Bob Twiggs of Stanford University wanted students to gain hands-on experience in designing, making and flying nanosatellites, but they needed to do it cheaply.

    Dream Chaser to use Europe’s next-generation docking system

    ESA and a team of European industrial contractors led by QinetiQ Space have finalised an agreement with Sierra Nevada Corporation for the use of Europe’s International Berthing Docking Mechanism on the Dream Chaser spaceplane.

    The Sierra Nevada Corporation (SNC) Dream Chaser is being developed as a reusable, lifting-body, multimission spacecraft capable of landing at commercial airports or spaceports that can accommodate large commercial aircraft anywhere in the world.

    Selected to provide cargo delivery, return and disposal services for the International Space Station under NASA’s Commercial Resupply Services 2 contract, it is a safe, affordable, flexible and reliable system, designed to provide crewed and uncrewed transportation services to low orbit destinations, such as the Space Station and future commercial space infrastructures.

    Spin Your Thesis! 2018 open for proposals

    Sometimes it’s good to get into a spin. Particularly if you are a student wanting to run a hyper-gravity experiment. For the ninth year, ESA’s Education Office is open to submissions for its Spin Your Thesis! programme.

    Spin Your Thesis! allows students to carry out experiments in hypergravity conditions at ESA’s Large Diameter Centrifuge (LDC). Very different from the desktop centrifuges found in ordinary laboratories, the LDC is a world-class instrument. It is eight metres in diameter, and so large that it is housed in its own hall at ESA’s technical heart (ESTEC), The Netherlands. It can hold an experiment of up to 80kg in mass and spin so fast that it simulates a pull of gravity up to 20 times larger than that experienced at Earth’s surface

    Saving time in space

    Working inside the International Space Station is sometimes like assembling complex furniture but with the tools and paper instructions continually floating out of reach. Astronauts also face situations unforeseen by the instructions. Communication delays with ground control to troubleshoot these occasions mean even more valuable time is lost. Now, ‘mobiPV’ is looking to help.

    Keeping the rhythm in space

    Space is an inhospitable environment for the human body but we adapt remarkably well. Within hours, the brain adjusts to the lack of an up or down, as if floating is all it has ever known. Now researchers are learning how our internal clock similarly adjusts to the restrictions of space. An ESA-sponsored experiment has found that while you can take the body out of Earth, you can’t take an Earth-based rhythm out of the body.
