NASA has begun constructing the SUV-sized Europa Clipper spacecraft that can examine Jupiter’s icy, ocean moon following its launch in October 2024. 

The US area company has introduced that Clipper is now being put collectively on the Jet Propulsion Laboratory in La Cañada Flintridge, Southern California. 

The Clipper mission goals to seek out out if Europa, Jupiter’s fourth-largest moon, hosts circumstances appropriate for all times utilizing ‘a complicated suite of science devices’.  

Europa, an icy moon with a hidden subsurface ocean, has a diameter of 1,940 miles (3,100 kilometres) – about 90 per cent the diameter of Earth’s moon. 

Europa is one among few places within the Photo voltaic System with liquid water, together with Earth and Saturn’s moon Enceladus, making it a goal of curiosity for NASA. 

The principle physique of the spacecraft is a big 10-foot-tall propulsion module, designed and constructed by Johns Hopkins Utilized Physics Laboratory (APL) in Laurel, Maryland. Right here, the Europa Clipper radio frequency (RF) panel is mechanically put in close to the highest of the propulsion module cylinders in a cleanroom at APL

In a press release, NASA stated that ‘nearly each element of the spacecraft could have been hand-crafted’. 

EUROPA: QUICK FACTS 

Europa is 90 per cent the dimensions of Earth’s moon.

It orbits Jupiter at a distance of about 484 million miles (778 million kilometers).

It completes one orbit of Jupiter each 3.5 Earth days.

Europa’s floor is generally stable water ice, crisscrossed by fractures.

However its subsurface ocean may include greater than twice as a lot water as Earth.

The moon has a really skinny oxygen ambiance – too skinny for people to breathe.

‘When it’s totally assembled, NASA’s Europa Clipper can be as giant as an SUV with photo voltaic arrays lengthy sufficient to span a basketball courtroom – all the higher to assist energy the spacecraft throughout its journey to Jupiter’s icy moon Europa,’ NASA stated.

‘Now, engineering parts and science devices are starting to stream in from throughout the nation and Europe,’ NASA stated. 

‘Earlier than yr’s finish, a lot of the flight {hardware} – together with a set of 9 science devices – is anticipated to be full.’  

Elon Musk’s agency SpaceX will present ‘launch companies’ for the Europa Clipper mission, which is because of blast off in October 2024 to check Europa by a sequence of fly-bys, NASA introduced final July. 

The spacecraft will launch on a Falcon Heavy rocket owned by Musk’s firm from NASA’s Kennedy House Heart in Florida, the area company added.  

‘NASA has chosen House Exploration Applied sciences Corp. (SpaceX) of Hawthorne, California, to offer launch companies for Earth’s first mission to conduct detailed investigations of Jupiter’s moon Europa,’ the company stated.

Europa Clipper technicians and engineers at NASA's Jet Propulsion Laboratory in Southern California work together in a cleanroom on Sept. 12, 2019. They bond thermal tubing to the spacecraft's Radio Frequency (RF) panel, which was built by APL. The tubing is part of a Heat Redistribution System (HRS) that pumps coolant all around the spacecraft and helps control its temperature as it travels through space

WHAT MAKES EUROPA SPECIAL? 

Europa has a water ocean beneath its icy floor – one of many key parts for all times.

The moon’s orbital path takes it deep into Jupiter’s magnetic discipline which quickly hurries up particles and traps them on the moon’s floor.

The ensuing radiation drives chemical reactions that result in an abundance of chemical compounds referred to as oxidants on the floor.

On Earth these oxidants react with compounds referred to as reductants to kind the vitality wanted for all times.

‘The overall contract award quantity for launch companies is roughly $178 million.’ 

Key mission aims are producing high-resolution pictures of Europa’s floor, decide its composition and search for indicators of latest or ongoing geological exercise.

The mission may even measure the thickness of the moon’s icy shell, seek for subsurface lakes and decide the depth and salinity of Europa’s ocean. 

Due to ground-based telescopes, scientists already know Europa’s floor is generally water ice.

Scientists have additionally discovered proof that beneath the ice crust is an ocean of liquid water or slushy ice. 

Based on NASA, Europa’s subsurface ocean may include greater than twice as a lot water as Earth. 

In 2020, Monica Grady, Chancellor at Liverpool Hope College, stated it’s ‘virtually a racing sure’ that Europa is house to alien life, which she thinks is ‘just like the intelligence of an octopus’. 

NASA will goal to seek out out if she’s appropriate with the launch of Europa Clipper, which can ‘ship a extremely succesful, radiation-tolerant spacecraft into a protracted, looping orbit round Jupiter to carry out repeated shut flybys of the icy moon’.

NASA didn’t reveal whether or not different firms had bid on the Europa Clipper launch contract, which marks NASA’s newest vote of confidence in Musk’s agency.

SpaceX has already carried a number of cargo payloads and astronauts to the Worldwide House Station (ISS) for the area company in recent times, aboard its Crew Dragon spacecraft.

Extra not too long ago, on November 11, 2021, NASA launched Crew 3, the third fully-fledged ‘operational’ crew NASA and SpaceX have flown to the ISS. The crew efficiently reached the ISS a few day after the launch.   

Crew 4 – the fourth crewed operational NASA flight of a Crew Dragon spacecraft – is about to launch on April 15, 2022. 

It would carry a four-person crew to the ISS – NASA astronauts Robert Hines, Kjell N. Lindgren and Jessica Watkins, in addition to Italian ESA astronaut Samantha Cristoforetti.  

WHAT DO WE KNOW ABOUT EUROPA AND WHY IS IT SO SPECIAL? 

Jupiter’s icy moon Europa is barely smaller than Earth’s moon.

Europa orbits Jupiter each 3.5 days and is tidally locked – identical to Earth’s Moon – in order that the identical facet of Europa faces Jupiter always.

It’s thought to have an iron core, a rocky mantle and a floor ocean of salty water, like Earth. 

Not like on Earth, nevertheless, this ocean is deep sufficient to cowl the entire floor of Europa, and being removed from the solar, the ocean floor is globally frozen over.

Many specialists imagine the hidden ocean surrounding Europa, warmed by highly effective tidal forces attributable to Jupiter’s gravity, might have circumstances beneficial for all times.

Nasa scientists are on the verge of exploring Jupiter’s ocean moon Europa for indicators of alien life.

Europa is our greatest shot of discovering organic life within the photo voltaic system, researchers say.

The area company is priming two probes, together with one that can land on its floor, to discover the distant moon intimately inside the subsequent decade, the company says.
