JUICE space probe built Airbus in France, he is preparing for an eight-year journey with a mission to explore the icy moons of Jupiter, a mission of the European Space Agency (WHICH) to confirm the existence of subterranean oceans that could harbor life.
In the clean room of the manufacturer Airbus, in the French city of Toulouse, THE JUICE [Jupiter Icy Moons Explorer, Explorador de las Lunas Heladas de Júpiter) es preparada para la primera parte de su viaje hacia el sitio de lanzamiento en la Guyana Francesa.
Un equipo de ingenieros, técnicos y científicos que llevan años trabajando para esta misión muestran con orgullo el aparato de 6,2 toneladas, que cuenta con 10 instrumentos científicos, una antena de 2,5 metros de diámetro e inmensos paneles solares que habrá que probar una última vez.
En algunos días, la nave espacial viajará en un contenedor hacia Kourou, donde será propulsada en abril por un cohete Ariane 5.
Una placa conmemorativa en homenaje a Galileo ha sido grabada en la parte trasera del satélite. El científico fue el primero en observar las lunas de Júpiter, en 1610.
La volcánica Ío y las heladas Europa, Ganimedes y Calisto fueron “las primeras lunas descubiertas” después de la nuestra, explica Cyril Cavel, jefe de proyecto JUICE para Airbus Defence & Space.
El científico muestra con orgullo la frase “Sidereus nuncius” [“el mensajero de las estrellas, en español] Italian astronomer, the first ever treatise on astronomy.
Four hundred years later, mankind is going to deeply explore the natural satellites of the gas giant.
Earth and Venus as a catapult
THE JUICE It will be the first probe to be launched into non-Earth satellite orbit as part of a science mission three and a half years after arriving in the Jupiter system.
It will also be the first European probe to exceed Martian orbit on a long 8-year journey that includes the first flybys of Earth and Venus – a maneuver called gravity – that allows it to gain more momentum to reach the Jupiter system it orbits. . The sun is at an average distance of 740 million kilometers.
“It’s like a catapult that gives us momentum until Jupiter”explains Nicholas Altobelli, Mission Science Director WHICH.
The probe’s 85m2 solar panels also need to be prepared to withstand temperatures of around 220 degrees Celsius below zero.
The ship must be put into orbit Jupiter (…) after a braking process carried out in full autonomy, which uses gravity assistance to reduce speed, in the opposite direction to that used at the beginning of the trip. “If the maneuver fails, the mission is over,” explains Cyril Kavel.
Target: Ganymede
THE JUICE will analyze the Jupiter system [que agrupa el planeta Júpiter y sus satélites] and will be launched into orbit around Ganymedelargest moon.
Its cameras, sensors, and radar will try to determine if it meets the conditions for life—bacteria, for example—in the oceans beneath the ice.
In order for life to take root, several conditions must be met. Among these are the presence of water in a liquid state, a source of energy such as the “tidal effects” that Jupiter’s gravity has on its moons, and contact with a rocky core that can provide the necessary chemical elements.
With magnetic signals Ganymede, THE JUICE can determine if water is in contact with the stone core.
If this were the case, it would allow the chemical elements to “dissolve in water,” Nicholas Altobelli explains.
The American probe Europa Clipper will join the expedition and explore the Europa satellite. The expected launch date is October 2024, arriving in the Jupiter system in 2030 thanks to the higher power of SpaceX’s Falcon Heavy rocket, chosen by NASA.
If both moons show signs of life support, the next step would be to send a lander. “This is part of the dream of scientists,” admits Cyril Cavel, “thrilled to learn that THE JUICE “will end his life on Ganymede”. (AFP)
