  • Sentinels for Copernicus

    Sentinels for Copernicus

    On 16 February 2016 at 18:57 CET (17:57 GMT), Sentinel-3A will be launched on top of a Rockot from the Russian Plesetsk Cosmodrome.

    This satellite will be the third Sentinel for the Copernicus Programme. Copernicus is the most ambitious Earth Observation programme to date. It will provide accurate, timely and easily accessible information to improve the management of the environment, understand and mitigate the effects of climate change and ensure civil security. This initiative is headed by the European Commission (EC) in partnership with the European Space Agency.

    ESA coordinates the delivery of data and is developing a new family of satellites, the Sentinels, specifically for the operational needs of Copernicus. The EC, acting on behalf of the European Union, is responsible for the overall initiative, setting requirements and managing the services. These services fall into six main categories: land management, the marine environment, atmosphere, emergency response, security and climate change.

    This video explains what the Sentinels represent within Copernicus.

    SCIENTIFIC NOTES:
    – Messages can also be encoded by altering the phase of the signal being sent from the antenna.
    – Phones use several (~8) frequencies at one time, and since there are limited frequencies (~100) for the tower to use, manages the sharing of them.

    Sentinel-3: Technology and heritage

    ESA’s new Earth observation satellite Sentinel-3A will soon be launched into orbit. Once more the European Space Agency proves it is on the forefront of monitoring our environment and the climate.

    Using state of the art and proven technology the Sentinel-3 satellite is a fabulous piece of engineering set to play a key role in the European Commission’s Copernicus programme. However this technological piece of craftsmanship is only possible as the result of earlier scientific missions such as ERS, Envisat and Cryosat, with Sentinel-3 building on their heritage.

    LISA Pathfinder prepares for liftoff (4K timelapse replay)

    This timelapse video shows the preparations for LISA Pathfinder’s launch at Europe’s Spaceport in Kourou, French Guiana. The video spans three weeks, starting on 12 November 2015 with the completed and fuelled spacecraft and ending on the 3 December launch day.

    Over this period, the spacecraft was attached to the payload adaptor of the Vega launcher, encapsulated within the half-shells of the rocket fairing, transferred to the launcher assembly area, and installed on top of Vega inside the mobile gantry, which was rolled back shortly before liftoff.

    LISA Pathfinder will test key technologies for space-based observation of gravitational waves – ripples in the fabric of spacetime that are predicted by Albert Einstein’s general theory of relativity.

    ESA Euronews: De mi az a nanoműhold?

    A nanoműholdak egyre fontosabbak lesznek az űrkutatásban, a Mars megfigyelésétől a Földre veszélyt jelentő aszteroidák felkutatásáig. A bennük rejlő potenciált mindenki igyekszik kiaknázni, a nagy űrügynökségektől a tudományos diákkörökig. Ez a helyzet a Mektory Űrközpontban, az észt főváros, Talinn műszaki egyetemén, ahol a diákok az első nanoműholdjuk Föld körüli pályára állítását készítik elő.

    – Azt hittem, soha nem fogok műholdat építeni, hiszen ilyesmit csak a NASA-nál csinálnak. Most meg műholdat építek az egyetemi laborban – hitetlenkedett az Euronewsnak Marta Hang, az űrközpont programasszisztense.

    A Mektory nanoműhold-programja egy nemzetközi egyetemi kezdeményezés, amelyben az oktatók és a hallgatók együttműködnek az űrkutatásban érdekelt és más technológiai cégekkel. A cél az, hogy felkészítsék a hallgatókat arra, hogy az űriparban helyezkedjenek el. A csapat jelenleg az első űrküldetését tervezi.

    – Egy kockaműholdat fejlesztünk, amely egy egységből áll, és távérzékelési célokat szolgál, vagyis képeket készít majd a Földről – magyarázza a Mektory Űrközpont igazgatója, Mart Vihmand.

  • Tim’s spacewalk highlights

    Tim’s spacewalk highlights

    On 15 January ESA astronaut Tim Peake and NASA astronaut Tim Kopra stepped outside of the International Space Station to replace a failed power regulator and install cabling.

    The meticulously planned and executed sortie was stopped early after Tim Kopra reported a small amount of water building up in his helmet. The two Tims worked in close cooperation with each other to return to the Space Station, with NASA commander Scott Kelly and cosmonaut Sergei Volkov waiting inside to help them out of their suits.

    They left the confines of the weightless research laboratory at 12:48 GMT after their five-hour preparations to don their spacesuits and purge their bodies of nitrogen to avoid decompression sickness.

    Tim Kopra went first to the far end of the Station’s starboard truss, with Tim Peake following with the replacement Sequential Shunt Unit. Swapping the suitcase-sized box was a relatively simple task but one that needed to be done safely while the clock was ticking.

    With their main task complete, the Tims separated for individual jobs for the remainder of their time outside but was told by Mission Control to return to the airlock earlier than planned.

    The 4 hour 43 minute spacewalk was the first for a British astronaut. The spacewalk officially ended at 17:31 GMT when the Tims began the repressurisation of the Quest airlock.

  • Asteroid Impact Mission (Spanish)

    Asteroid Impact Mission (Spanish)

    La misión AIM (Asteroid Impact Mission), candidata a ser desarrollada, actualmente en fase de diseño preliminar.

    AIM se lanzaría en octubre de 2020 y su objetivo es viajar al sistema binario de asteroides Dídimos para estudiar la luna Didymoon. El sistema Didimos cuenta con un cuerpo principal de unos 800 metros de diámetro y una luna que orbita alrededor de este cuerpo principal, de unos 170 metros de diámetro aproximadamente, está luna se la conoce con el nombre de Didymoon. El sistema Didimos se aproximará a 11 millones de kilómetros de la tierra en 2022.

    AIM escaneará la pequeña Didymoon en detalle con su cámara VIS, con imágenes térmicas y un radar de alta resolución para construir mapas detallados de su superficie y estructura interior.

    La nave principal de AIM llevará al menos tres sondas más pequeñas – el módulo de aterrizaje, Mascot-2, desarrollado por el Centro Aeroespacial Alemán (Mascot-1 ya está volando en la misión Hayabusa-2 de JAXA), así como dos o más CubeSats. Así, AIM pondría a prueba las comunicaciones ópticas y los enlaces inter-satelitales en el espacio profundo, una tecnología que será esencial para la exploración futura del espacio.

    Si se aprueba, AIM también será la contribución europea a la misión AIDA, Asteroid Impact and Deflection Assessment. En 2022, la sonda DART (Double-Asteroid Redirection Test), parte dirigida por la NASA, llegará al sistema binario y se estrellará contra Didymoon a una velocidad de unos 6 km/s.

    El impacto será observado por AIM y por sus CubeSats. A través de las imágenes de alta resolución de AIM se evaluará el tamaño y la profundidad del cráter tras el impacto. AIM realizará una segunda fase de mediciones para comparar detalladamente la estructura del objeto, así como su órbita al rededor del asteroide mayor, antes y después del impacto.

    NASA Administrator Charles Bolden on Commercial Space

    NASA is on a Journey to Mars and commercial space is a key component of our strategy to send American astronauts to the Red Planet in the 2030s.
    In 2010 when President Obama laid out his vision for space exploration, it may have been hard to believe that six years later we’d be regularly transporting cargo to the International Space Station on commercial spacecraft, or that we’d be on the verge of returning launches of American astronauts to the Station from U.S. soil on the spacecraft built by American companies.
    Today, that’s our reality.
    SpaceX and Orbital ATK are the first commercial space companies to deliver cargo to the ISS.
    We’ve also ordered the first missions from SpaceX and The Boeing Company — the first American companies that will carry American astronauts to space. The first astronauts are now training for test flights aboard commercial spacecraft in preparation for those missions.
    We are closer than ever before to sending American astronauts to Mars. We’re “insourcing” American jobs and empowering American entrepreneurs and innovators to expand the new commercial market in low-earth orbit.
    Today, we’re marking another significant milestone. We are announcing the companies that will continue our successful commercial cargo program until at least 2024. This phase of the program will allow us to continue using the Space Station as our springboard to the rest of the solar system and a test bed for human health in space.
    Our investment in commercial space is creating jobs and it’s bringing us closer to sending American astronauts to Mars. With the commercial cargo successes to date and our announcement today – I am very confident that commercial space will continue to propel our nation into the future – we’ll continue to Launch America.

    On Dec. 11 aboard the International Space Station, NASA’s Kjell Lindgren, Russian cosmonaut Oleg Kononenko and Kimiya Yui of the Japan Aerospace Exploration Agency, bid farewell to crew members remaining on the station — including Commander Scott Kelly, NASA’s one-year mission astronaut. The returning members of Expedition 45 then climbed aboard their Soyuz spacecraft for the trip back to Earth. They safely touched down hours later in Kazakhstan – closing out a 141-day stay in space.
