JUICE zum Jupiter


Nachfolgend auf die bereits auf dem Wege befindliche Juno Mission der NASA kommt dann zehn Jahre danach eine weitere Jupiter Mission unter Federführung der ESA. Dabei geht es vor allem um die Erkundung der drei großen Eismonde Europa, Ganymed und Callisto:

JUICE = JUpiter ICy moons Explorer

JUICE is Europe's next large science mission

JUICE is the first Large-class mission chosen as part of ESA's Cosmic Vision 2015-2025 programme.

It will be launched in 2022 from Europe's spaceport in Kourou, French Guiana, on an Ariane 5, arriving at Jupiter in 2030 to spend at least three years making detailed observations.

JUICE will continuously observe Jupiter's atmosphere and magnetosphere, and the interaction of the Galilean moons with the gas giant planet.

It will visit Callisto, the most heavily cratered object in the Solar System, and will twice fly by Europa. JUICE will make the first measurements of the thickness of Europa's icy crust and will identify candidate sites for future in situ exploration.

The spacecraft will finally enter orbit around Ganymede in 2032, where it will study the icy surface and internal structure of the moon, including its subsurface ocean.

ESA chooses instruments for its Jupiter icy moons explorer

21 Feb 2013 - The JUpiter ICy moons Explorer mission, JUICE, will carry a total of 11 scientific experiments to study the gas giant planet and its large ocean-bearing moons, ESA announced today.

Today, ESA's Science Programme Committee approved a complement of instruments that includes cameras and spectrometers, a laser altimeter and an ice-penetrating radar.

The mission will also carry a magnetometer, plasma and particle monitors, and radio science hardware. The instruments will be developed by scientific teams from 15 European countries, the US and Japan, through corresponding national funding.

Eleven instrument suites will be developed by scientific teams from Austria, Belgium, Czech Republic, Finland, France, Germany, Hungary, Ireland, Italy, Netherlands, Poland, Spain, Sweden, Switzerland, UK, US and Japan, through corresponding national funding.

List of selected experiments:

JANUS: Jovis, Amorum ac Natorum Undique Scrutator, camera system
MAJIS: Moons and Jupiter Imaging Spectrometer
UVS: UV Imaging Spectrograph
SWI: Sub-millimetre Wave Instrument
GALA: Ganymede Laser Altimeter
RIME: Radar for Icy Moons Exploration
J-MAG: Magnetometer for JUICE
PEP: Particle Environment Package
RPWI: Radio & Plasma Wave Investigation
3GM: Gravity & Geophysics of Jupiter and Galilean Moons
PRIDE: Planetary Radio Interferometer & Doppler Experiment

usembassy.gov - NASA Contributing to Europe’s Jupiter Mission

NASA has selected key contributions for a 2022 European Space Agency (ESA) mission that will study Jupiter and three of its largest moons in unprecedented detail. The moons are thought to harbor vast water oceans beneath their icy surfaces.

NASA’s contribution will consist of one U.S.-led science instrument and hardware for two European instruments to fly on ESA’s Jupiter Icy Moons Explorer (JUICE) mission. Jeffrey Plaut of NASA’s Jet Propulsion Laboratory in Pasadena, California, will be the U.S. lead for the Radar for Icy Moon Exploration experiment. The radar experiment’s principal investigator is Lorenzo Bruzzone of Università degli Studi di Trento in Italy.



Update: Arianespace and ESA announce Jupiter Icy Moons Explorer launch contract

The launch period for JUICE will start in mid-2022 aboard an Ariane 5 or an Ariane 64 Launch vehicle - depending on the final launch slot from Europe's Spaceport in French Guiana, South America.

The satellite will have a mass at liftoff of approximately six tonnes and will be placed in an Earth escape orbit in a direction to Jupiter starting a journey of 600 million kilometres. After a 7.5-year cruise, which includes gravitational assists from Earth, Venus and Mars, the spacecraft will enter orbit around the giant planet in October 2029.

The Jupiter tour includes several flybys of each planet-sized world, and ends with orbit insertion around Ganymede, the largest moon in the Solar System.


Das ergibt ein interessantes Rennen / Kooperation mit dem NASA Projekt Europa Clipper. Das ist ein über 4 Mrd. Dollar teures Flagship-Projekt (so nannte man das früher, heute heißt es Large Strategic Science Mission), also vom Kaliber James Webb Space Telescope, Hubble, Mars 2020 Rover.

Es ist aber noch nicht alles bis ins Detail durchgeplant. Start könnte zwischen 2022 und 2025 sein. Die Trägerrakete steht auch nicht fest. Sollte es tatsächlich das superschwere SLS sein, könnte der Europa Clipper bereits 2026 in einen Orbit um Jupiter und Europa einschwenken. Ob das aber überhaupt noch realistisch ist? :unsure: Möglich wäre aber auch eine Delta IV Heavy oder eine Falcon Heavy als Trägerrakete. Die sind zwar schwächer, fliegen aber schon. Ankunft wäre dann zwischen 2028 und 2031. Quelle: Europa Clipper - Wikipedia

Naja - ist noch viel Zeit. Und es wird noch so manches Budget-Meeting geben.
