  • What is… an eclipse?

    What is… an eclipse?

    What is a lunar eclipse? What is a solar eclipse? This short video explains the difference between these regularly occurring events that can be observed from Earth.

    The video uses a mix of ground- and space-based imagery of eclipses, including footage from the International Space Station, ESA’s Proba-2 satellite and the Japanese-led Hinode satellite.

    Remember: never look directly at the Sun, even when partially eclipsed, without proper eye protection such as special solar eclipse glasses, or you risk permanent eye damage.

    Resources beyond Earth with Angel Abbud Madrid | Space Bites

    Humans will have to breath, drink and eat while living on the Moon. They will need energy to perform tasks using their robotic companions and materials to build structures. For a sustainable approach to space exploration these resources cannot be carried from Earth but have to be found on the Moon itself.

    Angel Abbud Madrid is the Director of the Center for Space Resources at the Colorado School of Mines (CSM), where he leads a multidisciplinary research programme on the human and robotic exploration of space and the utilisation of its resources. He is also the Director of the CSM Space Resources Program, the first academic programme in the world focused on educating scientists, engineers, economists, entrepreneurs and policymakers in the developing field of space resources.

    Space Bites hosts the best talks on space exploration from the most inspiring and knowledgeable speakers from the field. Held at the technical heart of the European Space Agency in the Netherlands, the lectures are now also available on YouTube.

  • Hera mission

    Hera mission

    Hera is the European contribution to an ESA-NASA double-spacecraft mission intended to test whether a kinetic deflection technique can be used to shift the orbit of an asteroid. The target of the mission is a double asteroid system, called Didymos, which will come a comparatively close 11 million km to Earth in 2022. The 800-m diameter main body is orbited by a 170-m moon, informally called ‘Didymoon’.

    In 2022 NASA’s DART spacecraft will first perform a kinetic impact on the smaller of the two bodies, then Hera will follow-up with a detailed post-impact survey that will turn this grand-scale experiment into a well-understood and repeatable planetary defence technique.

    Hera will also gather crucial scientific data on asteroids as a whole by carefully studying the exterior and interior properties of both bodies in the system. The spacecraft will also host two 6-unit cubesats that will be deployed near Didymos to perform, for the first time ever, multi-point measurements in a “mother-daughter” configuration. A novel intersatellite link will be used to establish a flexible communications network supporting the close-proximity operations in very low-gravity conditions, a crucial step for future exploration activities around small bodies.

    Hera, a further optimisation of ESA’s earlier proposed Asteroid Impact Mission, is currently in Phase B1 of mission development in preparation of the Agency’s Council of Ministers at European Level in late 2019.

  • BepiColombo launch to Mercury

    BepiColombo launch to Mercury

    Enjoy this animation visualising BepiColombo’s launch and cruise to Mercury. Some aspects have been simplified for the purpose of this animation.

    The joint ESA-JAXA mission comprises the European Mercury Planetary Orbiter and Japan’s Mercury Magnetospheric Orbiter, which will be transported to the innermost planet by the Mercury Transfer Module. The animation highlights several key milestones, including the solar array and antenna deployments once in space, through to the arrival at Mercury seven years later. When approaching Mercury, the transfer module will separate and the two science orbiters, still together, will be captured into orbit around the planet. Their altitude will be adjusted until the Magnetospheric Orbiter’s desired orbit is reached. Then the Planetary Orbiter will separate and descend to its lower orbit, and the two craft will begin their scientific exploration of Mercury and its environment.

  • Horizons mission – Soyuz: launch to orbit

    Horizons mission – Soyuz: launch to orbit

    This unique video shows a full launch of the Soyuz MS-09: from liftoff to orbit.

    Watch the launch from inside the crew capsule with first-ever shots from outside the spacecraft recorded by cameras fixed to the exterior of the Soyuz.

    The intense launch lasts less than ten minutes whereby the Soyuz spacecraft is propelled 1640 km and gains 210 km altitude. Every second for nine minutes, the spacecraft accelerates 50 km/h on average as the rocket’s boosters burn their fuel and are discarded.
    See the astronaut’s reactions and what the spacecraft looks like as the main steps are carried out to get into orbit:

    -00:12 Launch command issued
    -00:10 Engine turbopumps at flight speed
    -00:05 Engines at maximum thrust
    00:00 Launch
    +1:54 Separation of emergency rescue system
    +1:57 First stage separation
    +2:38 Fairing separation
    +4:48 Second stage separation
    +4:58 Tail adapter separation
    +8:45 Third stage engine cut off having arrived in orbit
    +8:49 Soyuz separation, deploy solar arrays and antennae

    The astronauts, from left to right, are NASA astronaut Serena Auñón-Chancellor, Roscosmos commander Sergei Prokopyev and ESA astronaut and flight engineer Alexander Gerst launched in the Soyuz MS-09 spacecraft from the Baikonur cosmodrome in Kazakhstan to the International Space Station on 6 June 2018. ESA astronaut Matthias Maurer and ESA television host Richard Hollingham provide commentary taken from the live event.

    Hunched in their Sokol flight suits that offer protection in case of fire or depressurisation, the trio stay in the crew capsule of the Soyuz – the only module that is also designed to survive a return to Earth. The bags above their heads contain supplies for the International Space Station as every bit of space is used.

    During a Soyuz launch astronauts typically experience forces of up to 4g – having to work while being pressed into their seats with a force that is four times more than the gravity felt on Earth. The Soyuz commander uses a stick to press buttons as they are too far away from the control panel.

    The fluffy toys above the astronauts’ heads are mascots and good luck charms but also serve as a simple but effective test to see when the spacecraft is in orbit: when they start to float the spacecraft is weightless and orbiting Earth. Above Sergei is the mascot for the 2018 FIFA soccer World Cup held in Russia. Alexander took German children television icon “Die Maus” with him.

    The launch went as planned as the 50-m tall Soyuz rocket propelled the astronauts to their cruising speed of around 28 800 km/h.
    For this launch the astronauts took 34 orbits of Earth over two days to arrive at their destination spending their time in the cramped orbital module of the Soyuz that is no larger than a car. With limited communications and living space the astronauts had time to adapt to weightlessness and reflect on their mission ahead. They aligned their spacecraft with the International Space Station and approached the orbital outpost for docking on 8 June 2018. The files for this video were downloaded by the astronauts after arriving at the Space Station.

    Alexander is a returning visitor to the International Space Station, the first of ESA’s 2009 class of astronauts to be sent into space for a second time. During the second part of his mission Alexander will take over as commander of the International Space Station, only the second time an ESA astronaut will take on this role so far.

  • Fly over Neukum crater

    Fly over Neukum crater

    This movie, based on images taken by ESA’s Mars Express, showcases the 102 km wide Neukum Crater in the southern hemisphere of Mars.

    The crater is named for the German physicist and planetary scientist, Gerhard Neukum, one of the founders of ESA’s Mars Express mission who inspired and led the development of the high-resolution stereo camera on Mars Express.

    This complex impact crater has a diverse geologic history, as indicated by various features on the crater rim and floor. Particularly striking are the dark dune fields, likely made up of volcanic material blown in and shaped by strong winds.

    The crater’s shallow interior has been infilled by sediments over its history. It is also marked with two irregular depressions that may be a sign of a weaker material that has since eroded away, leaving behind some islands of more resistant material.

    Over time the crater rim has undergone varying degrees of collapse, with landslides and slumped material visible in the crater walls. Many smaller craters have also overprinted the rim and pockmarked the interior since Neukum Crater was formed, highlighting its long history.

    Neukum Crater is situated in Noachis Terra, one of the oldest known regions on Mars, dating back to at least 3.9 billion years.

    3 Ways Black Holes Could Break Physics

    What if the Earth were swallowed by a black hole? Would humanity’s legacy be gone forever? Or could you somehow get back that information from behind the event horizon?

    There are three possible answers to this question…but they all break physics as we know it!

  • Mars sample return

    Mars sample return

    Spacecraft in orbit and on Mars’s surface have made many exciting discoveries, transforming our understanding of the planet and unveiling clues to the formation of our Solar System, as well as helping us understand our home planet. The next step is to bring samples to Earth for detailed analysis in sophisticated laboratories where results can be verified independently and samples can be reanalysed as laboratory techniques continue to improve.

    Bringing Mars to Earth is no simple undertaking—it would require at least three missions from Earth and one never-been-done-before rocket launch from Mars.

    A first mission, NASA’s 2020 Mars Rover, is set to collect surface samples in pen-sized canisters as it explores the Red Planet. Up to 31 canisters will be filled and readied for a later pickup – geocaching gone interplanetary.

    In the same period, ESA’s ExoMars rover, which is also set to land on Mars in 2021, will be drilling up to two meters below the surface to search for evidence of life.

    A second mission with a small fetch rover would land nearby and retrieve the samples in a Martian search-and-rescue operation. This rover would bring the samples back to its lander and place them in a Mars Ascent Vehicle – a small rocket to launch the football-sized container into Mars orbit.

    A third launch from Earth would provide a spacecraft sent to orbit Mars and rendezvous with the sample containers. Once the samples are safely collected and loaded into an Earth entry vehicle, the spacecraft would return to Earth, release the vehicle to land in the United States, where the samples will be retrieved and placed in quarantine for detailed analysis by a team of international scientists.

  • Sentinel-3B highlights

    Sentinel-3B highlights

    The Copernicus Sentinel-3B satellite spent six weeks at the Plesetsk cosmodrome in Russia being carefully prepared for liftoff. After being shipped from France to the launch site, the satellite was tested, joined to the rocket launch adapter, sealed from view in the fairing and taken by train to the launch pad. Sentinel-3B lifted off on 25 April 2018 at 17:57 GMT (19:57 CEST).

    It joins its twin, Sentinel-3A, in orbit. The pairing of identical satellites provides the best coverage and data delivery for Europe’s Copernicus programme – the largest environmental monitoring programme in the world. The satellites carry the same suite of cutting-edge instruments to measure oceans, land, ice and atmosphere. While these data are fed primarily into the Copernicus Marine Environment Monitoring Service, all the Copernicus services benefit to produce knowledge and information products in near-real time for a wide range of applications. The Sentinel-3 mission is essential for applications for ocean and coastal monitoring, numerical weather and ocean prediction, sea-level change and sea-surface topography monitoring, ocean primary production estimation and land-cover change mapping.
