    NASA Celebrates Earth Day

    NASA uses the vantage point of space to increase our understanding of our home planet, improve lives and safeguard our future. The agency also develops new ways to observe and study Earth’s interconnected natural systems with long-term data records, shares this unique knowledge, and works with institutions around the world to gain new insights into how our planet is changing. Here’s a brief thirty second video showing some of the sights and sounds of our Earth and why it’s important to us all to appreciate our unique home in the solar system.

  • NASA Celebrates MESSENGER Mission Prior to Surface Impact on Planet Mercury

    NASA Celebrates MESSENGER Mission Prior to Surface Impact on Planet Mercury

    NASA held a panel discussion media on Thursday, April 16, to share scientific findings and technical accomplishments of the agency’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft.

    After more than 10 years in space, the highly successful mission will come to an end when it is expected to collide into planet Mercury at a speed of more than 8,750 miles per hour (3.91 km/sec) near the end of this month.

    Launched in August 2004, MESSENGER traveled 4.9 billion miles (7.9 billion kilometers) – a journey that included 15 trips around the sun and flybys of Earth once, Venus twice, and Mercury three times – before it was inserted into orbit around its target planet in March 2011. The spacecraft’s cameras and other sophisticated, high-technology instruments have collected unprecedented images and made other observations. Mission managers are preparing to impact Mercury’ surface in the next couple weeks.

    Participants featured were:

    · James Green, director, Planetary Science Division, NASA Headquarters, Washington
    · Sean Solomon, MESSENGER principal investigator; director, Columbia University’s Lamont-Doherty Earth Observatory, Palisades, New York
    · Helene Winters, MESSENGER project manager, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland
    · Daniel O’Shaughnessy, MESSENGER systems engineer, Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland

  • Italy to Indian Ocean

    Italy to Indian Ocean

    Similar to ESA astronaut Samantha Cristoforetti’s night timelapse over Italy and Egypt (https://www.youtube.com/watch?v=Lgw36RCQPvM) but taken during the day, this video takes you on a 30-second journey over Italy, passing Greece while flying over the Mediterranean Sea to follow the Nile and finish at the Indian Ocean.

    Looking out from the International Space Station’s Cupola observatory while circling Earth at speeds of 28 800 km/h, the 5500 km flight took Samantha around 12 minutes. Images from a Space Station camera were joined together to create this video and make the flight seem even faster.

    The astronauts on the Space Station spend as much time as possible on science. During her 40-hour working week Samantha runs many experiments from Italy’s ASI space agency and ESA, and takes part in even more from scientists all over the world.

    Samantha is living and working on board the International Space Station as part of the six-strong Expedition 42 and 43 crew. Follow her Futura mission at http://samanthacristoforetti.esa.int.

    Space food and the good side of lipid fat

    We could call them the good, the bad and the ugly! No, we are not talking of spaghetti westerns… Instead, we are talking about a type of fat called lipids. Often we speak badly about them, but some are essential to our health as they reduce chronic inflammation, help lower ‘bad’ cholesterol – LDL – and are a valuable aid in the prevention of cardiovascular disease.

    We asked Samantha Cristoforetti, ESA astronaut on board of the International Space Station for the Futura mission, to tell us about which king of healthy fats she and the other astronauts can enjoy while on orbit.

    Two solar eclipses for Proba-2

    As Europe enjoyed a partial solar eclipse on the morning of Friday 20 March 2015, ESA’s Sun-watching Proba-2 minisatellite had a ringside seat from space. Orbiting Earth once approximately every 100 minutes, Proba-2 caught two eclipses over the course of the morning.

    Proba-2 used its SWAP imager to capture the Moon passing in front of the Sun. SWAP views the solar disc at extreme ultraviolet wavelengths to capture the turbulent surface of the Sun and its swirling corona.

    Proba-3: Dancing with the stars

    Dancing is probably the oldest human artform – and now ESA’s Proba-3 precision formation-flying mission intends to extend the art of dance to space.

    Like dancers, a pair of minisatellites will move around each other, their relative positions maintained to millimetre-scale precision, as if they were both parts of one giant spacecraft.

    Their mission is to cast a shadow from one minisatellite onto another, in order to form an artificial total solar eclipse in space – then study the fine details of the Sun’s wispy atmosphere, the solar corona.

    Franco Ongaro, ESA Director of Technical and Quality Management; Frederic Teston, Head of System and Cost Engineering; Andrea Santovincenzo, ESA engineer and the project’s manager Agnes Mestreau-Garreau, explain how to go about teaching a space mission to dance.

    NASA Holds Expedition 42 Space Walk Briefing from Johnson Space Center in Houston

    As two NASA astronauts from the International Space Station’s Expedition 42 crew prepare to venture outside the orbital complex on Friday, Feb. 20, NASA Television provided a preview news briefing on Wednesday, Feb. 18. The preview briefing was held at NASA’s Johnson Space Center in Houston with the following panelists:

    Kenneth Todd, International Space Station Operations and Integration manager
    Tomas Gonzalez-Torres, Expedition 42 lead flight director
    Karina Eversley, Extravehicular Activity (EVA) # 29 officer
    Sarah Korona, EVA # 30 officer
    Arthur Thomason, EVA # 31 officer
    Expedition 42 Commander Barry Wilmore and Flight Engineer Terry Virts will exit the station from the Quest airlock for each of the three spacewalks around 7:10 a.m. NASA TV coverage of the approximately six-and-a-half hour spacewalks will begin at 6 a.m.

    Built by Boeing under contract to NASA, the International Docking Adapters are a critical component of the station’s reconfiguration to ensure long-term docking ports for future commercial crew and other visiting spacecraft. They will permit the standard station crew size to grow from six to seven, potentially doubling the amount of time devoted to research aboard the orbiting laboratory.

    The two new docking adapters will be launched to the station on a pair of SpaceX Dragon cargo spacecraft this year. Astronauts will install the first of two adapters on Pressurized Mating Adapter-2 on the forward end of the station’s Harmony module during a future spacewalk. The second adapter will be installed on Pressurized Mating Adapter-3 after it is relocated robotically to the space-facing port of Harmony later this year.

    The spacewalks will be the 185th, 186th and 187th in support of space station assembly and maintenance. Wilmore has conducted one spacewalk in his career last October. The spacewalks will be the first of Virts’ career.

  • Radiation testing for space

    Radiation testing for space

    The apparent void of space is actually awash in high-energy particle radiation, which can have just as harmful an effect on delicate satellite components as it does on living tissue. The threat to spacecraft varies greatly based on their orbits.

    Ali Zadeh, head of ESA’s Components Space Evaluation and Radiation Effects section explains how electrical, electronic and electro-mechanical (EEE) components – the fundamental building blocks of any space mission – are tested for this harsh environment, assessing their suitability for space.

    The Agency’s ESTEC technical centre in Noordwijk, the Netherlands, hosts a Cobalt-60 irradiation facility for highly-penetrating gamma ray testing, supplemented by a network of external European particle accelerator sites for electron, proton and heavy-ion radiation testing.

    Questo video, indirizzato a bambini tra i 6 e i 12 anni, racconta di Paxi, un piccolo alieno proveniente dal pianeta Ally-O che è venuto sulla Terra per incontrare nuovi amici e portare i bambini in avventurosi viaggi alla scoperta dello spazio. Questo è il primo di una serie di animazioni in cui Paxi, la mascotte dell’Education Office dell’ESA, descrive diverse caratteristiche del Sistema Solare, dell’Universo, i segreti del pianeta Terra e molto altro.
