JUICE Mission: A Groundbreaking Lunar-Earth Flyby Set to Break Records

Why in news?

• The European Space Agency ESA is eve closer to making history with its JUpiter ICy moons Explorer also known as JUICE Mission.
• This massive project is meant to shed light on the viability of life in these bodies: the Jovian moons of Europa, Ganymede and Callisto.
• A crucial aspect within the framework of the mission is the Lunar-Earth gravity assist, a manoeuvre incorporated for the first time, that involves both the Moon and the Earth to influence the trajectory, of the spacecraft.
• This great idea is not merely impressive in terms of technical possibility but also critical for the success of the entire mission of JUICE.

What is the JUICE Mission?

• Jupiter Icy moons Explorer or JUICE is one of the hallmark missions of ESA and the mission was initiated primarily to study Jupiter and its moons primarily.
• The mission is set to revolutionize our understanding of these distant worlds by focusing on three of Jupiter’s largest moons: , Europa, Ganymede and Callisto.
• These moons are considered to be the habitat of huge oceans beneath frozen shells, which makes them an object of extraordinary interest for scientists in the context of discussions on the existence of life on other planets.
  • Europa:
    • Europa has been noted for its shiftless surface of ice and this makes it among the most popular bodies in the entire solar system.
    • Many scientists hypothesize that it has a subsurface ocean that consists of liquid water heated by tides given by Jupiter’s enormous gravity.
  • Ganymede:
    • With a diameter of 2630 km Ganymede is to date the largest moon in the solar system and is even has its own magnetic field.
    • Since such a magnetic field appears to exist coupled with a possibly underlying ocean, Ganymede is one of the targets of the JUICE Mission.
  • Callisto:
    • Because of the abundance of impact craters, Callisto is regarded as one of the oldest terrains in the entire solar system.
    • Also Callisto is postulated to consist of a subsurface ocean; therefore, this satellite is included into the targets of the JUICE Mission.
• Initiated in April 2023, this mission is planned to arrive at the Jupiter in 2031, taking 8 years to travel.
• At this stage, JUICE will map the geology and morphology of the moons’ top layers, as well as their underground oceans, the composition of Jupiter’s atmosphere, and the characteristics of its magnetic field.
• These investigations will gather invaluable information that can shed some light on what perhaps remains one of humanity’s biggest questions – is there life out there in the space?

Execution of the Flyby: A Lit Double Play with Moon and Earth

• Another important and unique feature of the JUICE Mission is the so-called Lunar-Earth gravity assist (LEGA).
• This complicated operation will be conducted on August 19, 2023, and it is expected that it will be a turning point in the mission.
• Moon Encounter:
  • This flyby will start at 21:15 UTC of August 19, 2023, when JUICE is planned to approach the Moon nearly from its surface.
  • The spacecraft will enter into the lunar orbit in order to decrease by some degree the relative speed to enable the next phase of the action.
• Earth Approach:
  • About twenty-five hours from now JUICE will be at their nearest approach to the earth.
  • Here, there is a beauty of technology and the general laws of gravity of the Earth to ensure that the pace and direction of the spacecraft are altered even further.
  • When added together, these gravitational forces will alter the velocity of JUICE in a method which has otherwise, can only be achieved with the use of fuel.
• Schmoozing or engaging in light conversation is the initial step to getting close to the person that you want to interact or share your ideas with Depending on the nature and kind of jokes,
• telling jokes can be the second step to get close to a person or engage with him/her The final step depends on the timing of the jokes, it involves telling a hilarious joke and once the person laughs, one engages him/her
• The ability to master this maneuver depends To the slightest flaw is at risk the entire mission of the agents in question. From the floor, Spacecraft Operations Manager Ignacio Tanco said it was as if navigating through ‘a wide hallway with your car at top speed.

Challenges of the Maneuver

• The Lunar-Earth gravity assist is not only an engineering marvel; it is a roll of the dice. The task of using two celestial bodies to alter the according craft’s trajectory brings in the factors that makes it a difficult task.
• At launch and subsequently, the team must powerfully estimate the gravitational effects so that JUICE can board the right trajectory at the appropriate time.
• This is made worse by the need to integrate the manoeuvre with JUICE’s existing flight trajectory.
• The slightest mathematical error could result in the spacecraft going in the wrong direction as to completely miss the particular target.
• It would also not be effective as it would use a lot of time and money while at the same time, endangering the aims and goals of the primary mission.
• One of the researchers onboard, Dr. Olivier Witasse said that this maneuver was crucial for the mission because the JUICE Mission entails the study of the possible habitability of Jupiter’s moons.
• In the absence of an aerogravity assist at the Moon, getting to these moons in an even more efficient manner is virtually out of the question.

Benefits of the Flyby

• They are substantial if one considers the fuel savings which are realized from the Lunar-Earth gravity assist.
• This improvement is particularly essential to benefit the subsequent phases of the JUICE Mission due to the fact they want much less gas to perform near flybys of the Jupiter’s moons.
• Of the benefits of this maneuver one is the feasibility of conducting an extensive survey on Ganymede.
• It will also allow JUICE to get as close at any other spacecraft at 200 kilometers (120 miles) above the surface of Ganymede.
• From this position, the spacecraft shall be able to take clear images and data that could get the clues of the geology of the moon and its ability to support life.

Key Facts About the JUICE Mission

• Mission Name: Juice—JUpiter ICy moons Explorer
• Agency: European organisation for exploitation of meteorological data (EUMETSAT)
• Launch Date: April 2023
• Mission Duration: About eight years to get to Jupiter and several more years of discovery.
• Target Moons: Going to Europa, Ganymede, Callisto
• Scientific Instruments: Ten sensors whose objectives are the moons’ icy exterior and interior, subsurface ocean, magnetic field, and the composition of Jupiter’s atmosphere.
• Primary Objective: To know whether or not the Jovian moons could harbor life and to decipher the contingency of the existence of life in other planets.
• Secondary Objectives: For research in weather phenomenon and to have further information on the planet’s magnetic field that is crucial for other studies in planetary science.

The Significance of the JUICE Mission

• This, is the case and is why the JUICE Mission is a giant step in humanity’s search for the outer systems.
• This can be attributed to the fact that the mission concentrates on Jupiter’s moons with the aim of answering fundamentally questions concerning the existence of other planets that could host life forms.
• The proper flyby of the Lunar-Earth gravity assist will pave the way for JUICE to reach the Jupiter system to extensively investigate these enthralling objects.
• This mission is not only to visit several moons; this mission is about evolving the way that people view space and what is possible.
• Because of the application of gravitational assisting plus the incorporation of state of the art scientific instruments the JUICE Mission is among the most challenging space missions of the present era.
• As we await the results of this historic flyby, one thing is certain: the JUICE Mission as can be expected to revolutionalise how different Solar Systems and our own place in it is viewed.

Conclusion

• The JUICE Mission can be taken as one more example of how people never stop progressing and developing as well as never stop searching and learning.
