    Introducing: ESA Vigil

    It’s the first mission of its kind, set to monitor our active and unpredictable Sun and help protect us from its violent outbursts – and it has a new name.

    Once known as “Lagrange,” ESA’s upcoming space weather mission needed a new name that would reflect its vital role: helping to protect Earth’s infrastructure, satellites, inhabitants and space explorers from unpredictable but violent solar events like solar flares and ‘coronal mass ejections’.

    During the Name The Mission campaign, 5422 entries were submitted from across Europe and indeed around the world – and after weeks of deliberation, countless spreadsheets, three diverse and expert judges and a lively debate – a new name has been selected for our upcoming space weather mission: ESA Vigil.

    “We are thrilled with our mission’s new name,” explains Juha-Pekka Luntama, ESA’s Head of Space Weather.

    “When I first heard it, I thought it was just spot on. That is exactly what we do, we keep a vigilant watch and guard Earth”.

    In Latin, ‘vigilis exceptus’ means sentry, or guard, while ‘vigilia’ means wakefulness and the act of keeping a devoted watch, which resonates with the mission’s role – a devoted guardian, keeping constant watch over the Sun, for Earth.

    Protecting modern life, and life itself

    Solar storms can damage power grids, disrupt telecommunications and threaten satellites and the vital services they provide. At the same time, as we launch ever-more satellites into orbit we are creating increasing amounts of debris – dramatically increasing the risks of collision for current and future missions.

    These satellites have changed our lives and enlarged our perspective on Earth, but they – and the technologies they make possible on which modernity relies – are vulnerable.

    The protection of space assets is at the heart of ESA’s Vision for the future. To do this, the new Protect ‘accelerator’ proposes the development of ‘air traffic control for space’, as well as an early warning system to help us prepare for hazardous solar activity.

  • What are Lagrange Points? We Asked a NASA Scientist

    What are Lagrange Points? We Asked a NASA Scientist

    Lagrange points are places around a planet where the pull of its gravity, the Sun’s gravity and the motion of the orbit are balanced. Things at these points take very little energy to stay in place. NASA’s Lucy mission will visit Lagrange points where “Trojan asteroids” have been trapped for billions of years, holding clues to the formation of our solar system. NASA’s Dr. Adriana Ocampo has more.

  • Lagrange mission to provide solar warning

    Lagrange mission to provide solar warning

    Earth’s magnetic field protects life on Earth from the intense radiation and titanic amounts of energetic material our Sun blasts in every direction. However, astronauts and satellites in space, future explorers travelling to the Moon and Mars, and infrastructure on Earth such as power grids and communication systems remain vulnerable to these violent outbursts.

    For this reason, ESA is planning to send a satellite to monitor the ‘side’ of our Sun, from a gravitationally stable position known as the fifth Lagrange point. From here, the Lagrange satellite will detect potentially hazardous solar events before they come into view from Earth, giving us advance knowledge of their speed, direction and chance of impact.

  • ESA’s future Lagrange mission to monitor the Sun

    ESA’s future Lagrange mission to monitor the Sun

    Space weather describes the changing environment throughout the Solar System, driven by the energetic and unpredictable nature of our Sun. Solar wind, solar flares and Coronal Mass Ejections can result in geomagetic storms on Earth, potentially damaging satellites in space and the technologies that rely on them, as well as infrastructure on the ground.

    ESA’s future Lagrange mission will keep constant watch on the Sun. The satellite, located at the fifth Lagrange point, will send early warning of potentially harmful solar activity before it affects satellites in orbit or power grids on the ground, giving operators the time to act to protect vital infrastructure.

    ESA is now working with European industry to assess options for the spacecraft and its mission, with initial proposals expected early in 2020.
