CASEY STATION, Antarctica — Abreast a nice, big aperture in the ice and below the bean gray, midday Antarctic summer skies, six Adélie penguins stared at six men toiling with tools. The abysm in the ice ability accept been an agreeable access to the krill-rich amnion below. None of the associates of the tuxedoed recon affair affable into the hole, a aboveboard about six anxiety across. The accident of bobcat seals was aloof too great.

But had they leapt in, the penguins would accept apparent not a seal, but a robot.
In November, scientists and engineers from NASA’s Jet Propulsion Laboratory auspiciously acreage activated Bruie — the “Buoyant Departer for Under-Ice Exploration” — below the ice of eastern Antarctica. The accidentally operated departer was congenital to clamber forth the abject of sea ice and ice shelves. These tests on Earth accept a abiding ambition of one day gluttonous affirmation of activity below the blubbery arctic carapace accoutrement Jupiter’s ocean moon of Europa. Below that ice is three times added aqueous baptize than can be begin in all the oceans on Earth.

It will be years afore a aircraft from Earth acreage on Europa, which was best anxiously advised by NASA’s Galileo mission in the 1990s. The abutting automatic delving to appointment that apple will be Europa Clipper, appointed to barrage no eventually than 2025. When it arrives some years later, that aircraft will apogee Jupiter and appointment Europa dozens of times at altered angles to thoroughly browse and map the moon, advised one of the best candidates in our solar arrangement to be inhabited by some anatomy of exoteric life.

Any approaching for a lander visiting the Jovian moon is uncertain. But that hasn’t chock-full NASA’s engineers and scientists from developing technologies to aid its mission.
“Getting a agent like the afloat departer and added submersibles in the ocean of Europa is the abiding eyes for what we achievement to one day accomplish,” said Kevin P. Hand, the project’s science advance from the Jet Propulsion Laboratory. “It’s activity to appear afterwards Clipper and a lander on the surface. These forerunner missions would set the date for accepting through the ice and extensive the ocean.”
Bruie has been in development back 2017. The departer is the alliance of Jules Verne-like adroitness and the simplest apparatus accessible to build: little added than an arbor and two wheels, anniversary about the admeasurement of a ample pizza.
As its broadcast name implies, Bruie floats. The sea presses it adjoin the abdomen of the ice shelf, and as the departer crawls along, its sensors aggregate data. During its Antarctic acreage tests below the ice of O’Brien Bay abreast Casey Station, an Australian abject on the eastern allotment of the continent, the departer auspiciously endured three frigid three-hour deployments.

A fourth, analytical analysis kept it abysmal below the ice for 42 hours and 30 minutes. Andy Klesh, the project’s advance engineer, collection the departer application a laptop. While the departer can be piloted via accessory connection, during this mission, Dan Berisford, a automated engineer, anxiously fed it a attenuate chicken tether.
The abysmal departer crawled boring but ably. An onboard camera streamed video to the laptop and appear an Antarctica alike added conflicting than the surface. Except for the analytical penguins, the abstemious is abrupt and abundantly asleep bright to the horizon. But a few anxiety below, the departer begin all-inclusive amber webs of sea algae adhering to the ice. Fish would bathe up and crumb abroad at it. Bubbles of oxygen accumulated as photosynthesis pumped away.
On Europa, the absolute activity is in its ocean; if at aftermost the Jovian moon does get a departer that could get below its surface, it makes faculty that the apprentice would clamber on the abject of its ice shell. The radiation allure and geophysics of Europa’s apparent ability accommodate a apparatus for accouterment oxygen for activity in its depths.
To abstraction such life, any undersea departer would charge to be noninvasive.“While the thrusters of a accustomed underwater remote-operated agent can jet-blast aerial algaes off the basal of ice bedding during abutting encounters, Bruie acclaim tiptoes below them,” said Daniel Arthur, a technologist who works with Caltech and the University of Western Australia.

The departer analyzes the ice-ocean interface irenic and at constant distances, cartoon little ability — abnormally about to submarine-type drones. “Power will be in abbreviate accumulation on Europa,” Dr. Arthur said, “and we don’t appetite a ballista obliterating humanity’s aboriginal appointment with exoteric life.”
The ice-ocean interface on Earth is a area area physics, chemistry, and analysis all interact, said Alison Murray, an Antarctic scientist at the Desert Research Institute in Nevada. On our planet, the area is affluent with microorganisms. “We appetite to accept the habitability of these interfaces as able-bodied as the assortment of activity that calls them home,” said Dr. Murray. “In both cases, we can bigger accept whether this interface in the aphotic amnion of Europa ability absolutely be able to abutment life.”
Dr. Hand hopes that assignment on accessories like Bruie can drive development of robots to analyze Earth’s cryosphere, area ice meets oceans.
“It is my achievement that exploring Europa’s ocean can serve as a banishment function, from an engineering standpoint, to body those kinds of capabilities to get the aforementioned assignment done on planet Earth,” he said.
