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’.
‘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 collectively in a cleanroom on Sept. 12, 2019. They bond thermal tubing to the spacecraft’s Radio Frequency (RF) panel, which was constructed by APL. The tubing is a part of a Warmth Redistribution System (HRS) that pumps coolant throughout the spacecraft and helps management its temperature because it travels by area
The Europa Clipper Photo voltaic Array Mechanical Simulator (SAMS) is proven put in on the spacecraft’s propulsion module as part of a weeklong effort at APL in Laurel, Maryland, to verify that the photo voltaic array struts have been appropriately fabricated and put in onto the spacecraft construction. SAMS is a mass and geometry simulator for a single photo voltaic array wing that can be used as part of spacecraft structural testing

‘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’.

This radio dish will enable floor controllers to ship and obtain instructions and information between Earth and the spacecraft in Jupiter orbit – a couple of million occasions farther from Earth than the Worldwide House Station orbits

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.
The collaboration has concerned the primary launch of American astronauts from US soil in 9 years, because the area company give up flying area shuttles in 2011.

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.
