The Jupiter Icy Moons Explorer (JUICE) is scheduled to carry off on Friday, April 14, at 12:14 GMT from Kourou, French Guiana, to start its eight-year journey to Jupiter and its moons.
The mission was scheduled to take off on Thursday however was delayed due to lightning threat.
The brand new focused launch date is April 14, 2023, at:
· 08:14 a.m. Washington, D.C. time,
· 09:14 a.m. Kourou time,
· 12:14 p.m. Common time (UTC),

Led by the European House Company (ESA), the mission will orbit the biggest planet within the photo voltaic system and discover its icy moons, which scientists suppose may assist dwelling organisms.
JUICE will discover three attainable ocean-bearing moons – Europa, Ganymede and Callisto. Beneath their icy surfaces are regarded as big oceans of water – a vital ingredient for all times as we all know it.
Nicolas Altobelli, a JUICE undertaking scientist at ESA, stated it might be “the primary time that we discover habitats past the frost line” between Mars and Jupiter.
Past that line, temperatures plummet and “liquid water can now not exist on the floor”, Altobelli advised AFP information company earlier this yr.
The orbiter will probably be launched by the Arianne 5 rocket, which was beforehand used to launch the James Webb House Telescope.
That is the primary mission by the ESA to a Jovian orbit system and the primary mission to a moon aside from Earth’s.
Why is a mission to Jupiter essential?
Jupiter is about 318 occasions the dimensions of Earth and has 80 to 95 moons orbiting it, in response to NASA.
JUICE will examine Jupiter’s gaseous advanced floor in depth and its relationships with the oxygen and icy sub-surface saltwater ocean moons.
The orbiter could have 10 state-of-the-art devices on board which are a number of the strongest ever despatched into the photo voltaic system. 9 of the devices are led by European companions and one by NASA.
By July 2031, the spacecraft could have entered Jupiter’s orbit, from which it’ll probe Ganymede, Europa and Callisto.
There have been seven missions to Jupiter to date. NASA’s Juno remains to be ongoing and its Clipper is about to launch later this yr.
Jupiter’s moons vs Earth
JUICE will discover three of Jupiter’s largest moons – Ganymede, Callisto and Europa.
There’s hope Jupiter’s icy moons could have some type of dwelling organisms, stated Carole Larigauderie, JUICE undertaking head at French area company CNES.
“On Earth, we nonetheless discover life kinds on the backside of the abyss. Tiny microbes corresponding to micro organism and archaea have been discovered to have the ability to survive on Earth with out daylight, elevating hopes that life elsewhere will be capable of do the identical. In addition to water and vitality, life wants vitamins,” she stated.
Ganymede is the biggest moon within the photo voltaic system, in response to NASA, and Earth is about 2.4 occasions greater than it. It’s bigger than the planet Mercury. It’s the solely moon within the photo voltaic system that possesses its personal magnetic discipline, like Earth.
JUICE is predicted to succeed in Ganymede’s orbit by 2034, the place it’ll fly by the planetary mass 12 occasions.
The mission’s essential objectives for Ganymede are to discover its magnetic discipline and hidden ice ocean and examine its habitability.
Callisto is believed to have the oldest floor within the photo voltaic system. Earth is about 2.6 occasions the closely cratered object, in response to NASA.
JUICE is predicted to fly by the Callisto 21 occasions and get as shut as 200km (124 miles) to it. As soon as there, it’ll examine the surroundings round early Jupiter.
In line with NASA, Earth is about 4.1 occasions the dimensions of Europa and is believed to have a younger and lively floor which will vent water vapour to area through plumes and geysers.
JUICE will make two flybys round Europa to seek for any pockets of water, discover the floor, and search for any indicators of exercise.
If a number of of Jupiter’s moons tick all of the containers to host life, the “logical subsequent step” can be to ship a mission to land on the floor, stated Cyril Cavel, JUICE undertaking supervisor at producer Airbus.
Though there aren’t any plans for such a mission, which may definitively show the existence of life past Earth, “that’s a part of the dream”, he stated.
