San Francisco has long used the Pacific Ocean as a rest room. When it rains heavily, the hilltop town can't store all of the storm sewage and sewage that flows to a seaside treatment plant in a single old pipe, so some head out to sea. Now, in a case with national implications, San Francisco is hoping the U.S. Supreme Court will allow the corporate to often pollute the oceans without violating the federal Clean Water Act.

Although San Francisco has lived under this regulatory construct for a long time, it has now decided to check the bounds of federal regulations with a right-leaning Supreme Court known for restricting environmental laws.

It's greater than ironic that San Francisco is often the American right's favorite punching bag, with Florida's Ron DeSantis once showing a map of it Defecation points for homeless people on the town while debating California's Gavin Newsom. But now San Francisco is attempting to benefit from this notoriously right-wing court.

While town denies that its legal challenge has anything to do with how Donald Trump fundamentally transformed this court during his presidency, the timing speaks for itself. San Francisco is a regressive city in relation to water.

It's California's Trumpsville.

Nothing lower than 12 other states fight San Francisco in court. This also applies to the Attorney General of California Rob Bonta. This also applies to the Biden administration, which has taken San Francisco to court for failing for years to modernize a Nineteenth-century sewage system.

But San Francisco doesn't appear to care. All it wants is five black-clad judges in Washington, DC, to strike down some regulations. And within the face of judgment oral arguments earlier this month, San Francisco could also be on its method to weakening environmental protections for the remainder of the nation.

“We know that the San Francisco system results in 196 million gallons of wastewater being dumped onto San Francisco beaches,” argued Frederick Liu, an attorney for the federal Environmental Protection Agency. “We know that sewer backups occur in homes and businesses. We know that their infrastructure is aging and failing. We know that the discharges lead to excessive concentrations.”

Is SF really the victim?

Still, San Francisco looks at itself the victim.

“San Francisco is therefore subject to severe criminal and civil penalties even if it otherwise complies with its 300-page approval,” argued Assistant Attorney General Tara Steeley. “It doesn’t tell permit holders in advance what we need to do to control our discharges.”

San Francisco's water management reeks of arrogance.

The system begins by storing water in Yosemite National Park's Hetch Hetchy Valley, a glacially carved wonder that now lies underwater. The untouched snowmelt then flows into town. There, after San Franciscans flush their toilets, little or no water is reused through recycling – an enormous missed opportunity. Rather, the treated wastewater either leads to San Francisco Bay or the Pacific Ocean when it doesn't rain. When it pours, the system can discharge untreated wastewater.

Sacramento is the opposite major California city with an identical “combined” system, with a pipe for stormwater and wastewater downtown. But Sacramento isn't in court over its approval. It treats “practical” all wastewater before discharge into the Sacramento River.

At issue is San Francisco's waterfront facility, which is just unable to adequately treat the waste of 1 / 4 of 1,000,000 San Francisco residents when it rains. The plant plunges into the ocean at seven locations near the coast and at one location 5.3 kilometers into the ocean.

San Francisco welcomes that the Clean Water Act has allowed regulators to impose numerical limits on discharges and their components. However, it opposes broad prohibitions on pollution, contamination or making a nuisance, on this case known as “general prohibitions”.

Supreme Court Justice Brett Kavanaugh seemed outraged by the thought.

Speaking to Steeley, Kavanaugh said, “You're facing millions of dollars and possible prison time even though you didn't know in advance what your liabilities were,” an issue “that's written into the law.”

No lawyer could cite a case during which a wayward wastewater operator ever faced prison time. Rather, Liu told the court that state and federal regulators needed to resort to some general permit conditions because San Francisco made it inconceivable to do otherwise.

“We were unable to include the limitations of this adjustment in this permit because San Francisco withheld from us the very information we would need to do so,” Liu said.

Real World Impact

State and federal authorities are fed up with the blockades sued San Francisco hoping to force town to modernize its sewage system.

“The city has done virtually nothing to invest in improving its combined sewer system since the mid-1990s,” said Eric Buescher, an attorney for the environmental group San Francisco Baykeepers.

The lawsuit, currently in its early stages, goals to stop further clean water violations and civil penalties. Steeley told the Supreme Court that penalties could possibly be as high as $10 billion. Liu said they weren’t calculated. In principle he is true, the truth is that the case remains to be removed from a verdict.

Liu appeared to bring the right-wing justices to a standstill as he outlined the real-world implications of striking down the Clean Water Act as San Francisco wants.

The EPA has long since approved permits for countless farmers and construction projects in 14 days, provided they largely promise to comply with environmental laws. If the courts were to force regulators to impose specific numerical discharge limits on these routine permits, what’s now taking days could drag on for months. And that will “undermine the small business economy,” Liu said.

If the court were to achieve such a compromise, San Francisco's own recalcitrance to offer information that the federal government supposedly doesn’t have could be doomed to failure.

San Francisco's water management stays stuck within the Nineteenth century by defending a sewage system of that era. It could advance into the twentieth century by adopting the environmental laws of that point of their implementation. And it could make the leap into the fashionable world by joining its urban water peers, particularly those in Southern California, in recycling Sierra water over and all over again. Diversifying its Sierra-centric water portfolio would cut back San Francisco's dependence on Yosemite. Such a prospect is one which town's outdated water orthodoxy has never been in a position to fathom.

Pacific shouldn't be San Francisco's biggest foul that it might probably get away with.

California's most notorious Trump city will remain this fashion until it cleans up its water law in some ways.

My favorite place on this planet will not be a hard and fast place. It is the JOIDES resolutionan internationally funded research vessel that spent its entire service consistently on the move, from the depths of the Antarctic to high within the Arctic.

Since 1985, scientific expeditions have drilled 370 kilometers of soil using this unique ocean-going laboratory. Sediment and rock cores – long cylindrical samples that provide a novel view of the ocean floor. The cores come from 1000’s of various locations and permit scientists from many universities all over the world to check changes contained in the Earth.

They also provide a window into the history of our planet. The seafloor preserves a geological library that documents tens of millions of years of climate change and evolution.

Unfortunately, the JOIDES Resolution, also generally known as JR, can have set sail for the last time. It docked in Amsterdam on August 2, 2024, with no clarity on how the $72 million per yr needed to operate the vessel could be raised. The bulk of this funding comes from the U.S. National Science Foundation, which announced in 2023 that it will wouldn’t finance the JR beyond 2024 since the contributions of international partners couldn’t keep pace with the rising costs. The crews have begun Removing scientific equipment from the ship.

The National Science Foundation says it would support ongoing research using existing core samples and work with scientists to plan the longer term of scientific ocean drilling. But for me and plenty of other scientists, the associated fee of running the JR is small in comparison with the damage attributable to a single large earthquake – just like the 2011 Tohuku-Oki quake in Japan. estimated at $220 billion – or the Trillions of dollars Damage attributable to climate change. Ocean core research helps scientists understand such events in order that societies can plan for the longer term.

A floating laboratory

No other ship has the capabilities of the JR. The ship is 469 feet (143 meters) long – 50% longer than a football field. It has greater than 5 miles (8 kilometers) of drill pipe It connects the ship to the seabed and the underlying layers, enabling core samples from the seabed to be transported to the ship.

The JRs dynamic positioning system means that you can stay in a single place for days or perhaps weeks. Only two other ships on this planet have this ability: the Chikyua bigger ship operated by Japan in Japanese waters, and a brand new Chinese drilling ship called the Mengxiang.

I made eight two-month expeditions with the JOIDES Resolution, mostly at high latitudes near the poles to check past climates. Each trip involved about 60 scientists and technicians and 65 crew members. Once the ship left port, operations ran 24 hours a day, every single day. We all worked 12-hour shifts.

These trips might be exhausting, but normally the joy of latest and infrequently unexpected discoveries and the camaraderie of the opposite participants made the time fly by.

Insights from JR expeditions

As early because the Sixties, geologists began to know that the Earth’s continents and oceans should not static. Rather, they’re a part of movable plates within the Earth's crust and upper mantle. The movement of the plates, especially where they collide with one another, creates earthquakes and volcanoes.

Marine sediment cores can penetrate a mile or more into the Earth's crust. They offer the one method to investigate continuous changes in tectonic plate interactions, study climate and ocean evolution, and explore the boundaries of terrestrial life. Here are 4 areas where the small print of those processes are starting to emerge:

Formation of tectonic plates

Oceanic crust Is fundamentally different from the crust that lies beneath the continents. When I first heard about it within the Nineteen Seventies, the model for its formation and structure was easy:

– Lava rose from magma chambers beneath chains of seafloor volcanoes called ocean ridges.

– It poured onto the ocean floor and formed a dark, often glassy volcanic rock called basalt.

– In the deeper, slowly cooling magma chamber, crystalline minerals formed, creating rocks with a granite-like texture.

– Over tens of millions of years, this latest crust moved away from the ridges and have become cooler and denser.

But the cores recovered by the JOIDES resolution and the investigations with Underwater robots, so-called submersiblesshowed that this view was incorrect. They showed, for instance, that seawater circulates through the crust and changes its composition and the chemistry of seawater itself.

Core studies also showed that the Earth's mantle – a foundation believed to lie deep beneath the surface – is moving and expanding upward on huge, previously unknown fault zones. to the surface of the ocean crustThe coat could provide clues to the origin of life.

These findings modified scientists’ fundamental understanding of the structure of our planet.

Climate records within the ocean crust

I’m particularly inquisitive about the sediments which might be deposited on the ocean crust. These deposits contain tiny microfossils of plankton, including organisms akin to Diatoms and coccolithophores that live to tell the tale or near the ocean surface. While they perform photosynthesisThey absorb carbon dioxide from the atmosphere and produce half of all of the oxygen we breathe.

Plankton species vary depending on the temperature and chemical composition of the seawater. When they die and sink to the ocean floor, they preserve a wonderful record of past climates. Scientists use them to know how the Earth’s climate has warmed and cooled prior to now.

Another source of knowledge is sediment that falls from melting icebergs. Glaciers pick up rock as they flow over land. When they reach the ocean, pieces of it break off and form icebergs. The ice melts when exposed to warmer sea water, and the rocks fall to the ocean floor. These Rock deposits in sediments are a record of past transitions between warm and cold climates.

Record destruction and recycling

Most of the Pacific Ocean and a few areas of the Atlantic Ocean lie in zones that convergent edgeswhere tectonic plates grind against one another. This process pushes pieces of ocean crust and sediment into the Earth, where they melt and are eventually recycled into latest crust, often in the shape of volcanoes.

Huge faults along these edges can trigger enormous earthquakes, just like the one in 2011. Tohoku-Oki earthquake off the east coast of Japan. Core samples taken near such faults help scientists understand the forces that cause these events. They also create openings into which instruments might be inserted to watch future earthquakes.

Core samples from convergent margins have also make clear how volcanoes form and the way they affect long-term climate change by Produce carbon dioxide emissions.

The limits of earthly life

In the late Nineteen Seventies, exotic latest types of terrestrial life were discovered within the Pacific in zones where oceanic crust was forming. At plate boundaries, cold seawater seeped down through cracks within the crust. There it was reheated by hot magma and shot up through openings that scientists call Hydrothermal springs.

The hot water contained minerals that cooled after they got here into contact with cold seawater and hardened into chimney-like structures across the openings. Hundreds of life forms, including microbes, mussels and tube worms, colonized these structuresThey thrive near zones of high pressure and temperatures of as much as 120 degrees Celsius.

JR core drilling later revealed other life forms surviving deep within the ocean floor, under conditions of extreme lack of oxygen and energy. Scientists know almost nothing in regards to the diversity of those organisms or the metabolic strategies they use to survive of their demanding environment. Understanding how they thrive could support missions to other planets, akin to Saturn's moon Enceladus and Jupiter's moon Europa, which underground oceans that would harbor life.

What’s next for scientific ocean drilling?

The National Science Foundation has established a committee to think about what capabilities a brand new drilling ship must have, and Congress can Providing funds for extra JR expeditions in 2025. Given how much science still doesn’t learn about Earth's history and the challenges humanity faces in adapting to climate change, my colleagues and I hope that the JOIDES Resolution will still give you the chance to set sail again and that a brand new ship will eventually take up its mission.

Using a surprising technique, scientists have been in a position to observe how the Earth's oceans are changing. Neither special robots nor artificial intelligence are used. Instead, seals are tagged.

Several species of seals live in and around Antarctica and recurrently dive greater than 100 meters deep in quest of their next meal. These seals are experts at swimming through the strong ocean currents of the Southern Ocean. Their tolerance of deep waters and skill to navigate strong currents make these adventurous creatures perfect research assistants to assist Oceanographers like my colleagues and I Study the Southern Ocean.

Sealing sensors

For twenty years, researchers have attached tags to the foreheads of seals to gather data in distant and inaccessible regions. A researcher tags the seal during mating season, when the marine mammal comes ashore to rest, and the tag stays attached to the seal for a yr.

A researcher sticks the mark on the seal’s head – Marking of seals has no influence on their behaviorThe tag is removed yearly when the seal loses its fur and grows a brand new one.

The transmitter collects data while the seal dives and transmits its location and scientific data back to researchers via satellite when the seal surfaces for air.

First suggested in 2003Seal marking has develop into a International cooperation with strict standards for sensor accuracy and comprehensive data sharing. Advances in satellite technology now allow scientists to access data collected from a seal almost immediately.

New scientific findings due to seals

The tags attached to the seals are often equipped with sensors for pressure, temperature and salinity. These sensors are used to evaluate the rising ocean temperatures and changing currentsThe sensors often also contain chlorophyll fluorometers, which may provide data on the phytoplankton concentration within the water.

Phytoplankton are tiny organisms which form the idea of the ocean food web. Their presence often signifies that animals comparable to fish and seals are nearby.

The seal sensors may give researchers insight into the consequences of climate change within the Antarctic. Around 150 billion tons of ice melts from Antarctica yearlywhich contributes to global sea level rise. This melting is attributable to warm water being transported to the ice shelves by ocean currents.

With the info collected by seals, oceanographers can have described a few of the physical pathways This warm water reaches the ice shelves and currents transport the melted ice away from the glaciers.

Seals recurrently dive beneath sea ice and near glacier ice shelves. Sampling in these regions using conventional oceanographic methods is difficult and might even be dangerous.

Beyond the open Southern Ocean, away from the Antarctic coast, seal data have also make clear one other pathway resulting in ocean warming. Excess heat from the atmosphere moves from the ocean surface, which is in touch with the atmosphere, downward into the ocean interior in highly localized regionsIn these areas, the warmth reaches the deep sea, where it can’t be dissipated by the atmosphere.

The ocean stores many of the heat energy released into the atmosphere by human activities. Understanding how this heat moves helps researchers monitor oceans across the globe.

The behavior of seals is influenced by the physics of the oceans

The seal data also provides marine biologists with information concerning the seals themselves. Scientists can determine where seals are foraging. Some regions, Fronts are hotspots for Elephant seals attempting to find food.

In fronts, the ocean circulation creates turbulence and mixes the water in a way that Nutrients to the ocean surfacewhere phytoplankton can use them. As a result, phytoplankton blooms can occur on fronts, attracting fish and seals.

Scientists are using the info from the tags to see how seals are adapting to the changing climate and warming oceans. In the short term, seals may gain advantage from increased ice melting across the Antarctic continent, as they’ll live in coastal areas with Holes within the ice. Rising temperatures under the ocean surfacecan, nonetheless, change the placement of their prey and ultimately endanger the survival of the seals.

Seals have helped scientists understand and monitor a few of the most distant regions on Earth. On a changing planet, seal transmitter data will proceed to supply observations of their marine environments, with critical implications for the remainder of the Earth's climate system.

Marine tourism and recreation supports greater than 320,000 jobs and goods and services valued at $13.5 billion in Florida. But in the summertime of 2023, when the water temperature off Miami reached as much as 37.8 degrees Celsius, a swim within the sea became significantly less attractive.

The way forward for some jobs and businesses across the ocean economy has also grow to be more uncertain as oceans warm and damage from storms, sea level rise and maritime heatwaves increases.

Sea temperatures were Warm up within the last century and Record highs last 12 months, mainly as a result of rising greenhouse gas emissions from the combustion of fossil fuels. Scientists estimate that greater than 90 % of the surplus heat attributable to human activities, was absorbed by the ocean.

This warming, hidden for years in data of interest only to oceanographers, now has profound consequences for coastal economies around the globe.

Understanding the role of the ocean within the economy is something I work on for greater than 40 years, currently at Center for the Blue Economy from the Middlebury Institute of International Studies. Mostly I study the positive contributions of the ocean, but that has began to vary, sometimes dramatically. Climate change has made the ocean a threat to the economy in some ways.

The dangers of sea level rise

One of the most important threats to the economy from ocean warming is rising sea levels. Water heats up, it expands. Together with the meltwater from glaciers and ice sheets, the thermal expansion of the water has led to increased flooding in low-lying coastal areas and the longer term of the island states at risk.

In the USA, rising sea levels will soon overwhelm Jean Charles Island in Louisiana and Tangier Island within the Chesapeake Bay.

Flooding at high tide, even on sunny days, is becoming more common, for instance in Miami Beach; Annapolis, Maryland; Norfolk, Virginia; and San Francisco. Flooding has greater than doubled since 2000 and is on the approach to tripling by 2050 along the country's coasts.

Rising sea levels are also pushing saltwater into freshwater aquifers, that are used to supply water for agriculture. The strawberry harvest in coastal California is already affected.

These impacts are still small and localized. Much greater impacts are related to storms which might be amplified by rising sea levels.

Higher sea levels can worsen storm damage

Warmer ocean water fuels tropical storms. This is one in every of the explanation why meteorologists are warning of a severe hurricane season in 2024.

Tropical storms pick up moisture over warm water and transport it to cooler areas. The warmer the water, the faster the storm can form, the faster it could actually intensify, and the it could take longerleading to destructive storms and heavy rains that may flood cities even removed from the coast.

When these storms hit the already raised sea level, the waves and storm surge can dramatically enlarge the coastlines. flooding.

Tropical cyclones caused greater than $1.3 trillion in damage within the United States from 1980 to 2023, with a median cost of $22.8 billion per storm. Much of this cost was borne by taxpayers.

It's not only tropical storms. Maine saw what can occur when a winter storm in January 2024 created tides 5 feet above normal which filled the coastal roads with sea water.

What does this mean for the economy?

The potential future economic damage from sea level rise is unknown since the pace and magnitude of sea level rise are unknown.

According to at least one estimate, the prices of sea level rise and storm surges alone can be over $990 billion this century. Adaptation measures could only reduce these costs by 100 billion US dollarsThese estimates include direct property damage and damage to infrastructure akin to transport, water systems and ports. They don’t include impacts on agriculture as a result of the intrusion of saline water into aquifers, Agriculture.

Heatwaves within the sea cause difficulties for fisheries

Rising sea temperatures also affect marine life by causing extreme events called marine heatwaves and more gradual, longer-term temperature fluctuations.

In spring 2024, one third of the worldwide oceans Experience heat wavesCorals fight through their fourth global bleaching event in records, as warm ocean temperatures cause them to expel the algae that live of their shells and provides the corals color and food. While corals sometimes get better from bleaching, akin to Half of the world's coral reefs have died since 1950, and their The future after the center of this century is bleak.

The lack of coral reefs is greater than just their beauty. Coral reefs function breeding grounds and feeding grounds for hundreds of fish speciesAccording to NOAA estimates, about half of all federally managed fisheriesincluding snappers and groupers, rely upon reefs sooner or later of their life cycle.

Warmer waters cause fish to migrate to cooler areas. This is particularly evident in cold-water-loving species akin to lobsters, that are steadily moving north to flee warming seas. The once robust lobster fishery in southern New England is decreased significantly.

In the Gulf of Alaska, rising temperatures have nearly worn out snow crabs and shut down a $270 million fishery. completely closed for 2 yearsA serious heat wave off the Pacific coast spanned several years within the 2010s and affected fisheries between Alaska and Oregon.

That is not going to change anytime soon

The gathered ocean heat and greenhouse gases within the atmosphere are influence sea temperatures for hundreds of yearseven when countries reduce their greenhouse gas emissions to zero by 2050 as hoped. So while the oceans Temperatures vary from 12 months to 12 monthsThe overall trend is prone to proceed for at the least one other century.

There isn’t any cold water tap we are able to simply activate to quickly bring ocean temperatures back to “normal,” so communities might want to adapt while all the planet works to slow greenhouse gas emissions to secure the ocean economy for the longer term.

Saturn has 146 confirmed moons – greater than some other planet within the solar system – but one named Enceladus stands out. It seems to have the ingredients for all times.

From 2004 to 2017, Cassini – a joint mission between NASA, the European Space Agency and the Italian Space Agency – examined Saturn, its rings and moons. Cassini provided spectacular insights. Enceladus is just 504 kilometers across and hosts an ocean of liquid water beneath its icy crust that stretches across the whole moon.

Geysers on the moon's south pole shoot grains of gas and ice formed from seawater into space.

Although Cassini engineers didn't expect to investigate the ice grains actively emitted by Enceladus, they did grab one Dust analyzer on the spaceship. This instrument measured the emitted ice grains individually, informing researchers concerning the composition of the subsurface ocean.

As a planetary scientist and astrobiologist For those that study ice grains from Enceladus, I’m fascinated about whether there’s life on this or other ice moons. I also want to grasp how scientists like me were capable of discover it.

Ingredients for all times

Just just like the Earth's oceans, The ocean of Enceladus incorporates saltmost of it’s Sodium chloride, commonly referred to as table salt. The ocean also incorporates various carbon-based compounds and has a Process called tidal warming that creates energy within the moon. Liquid water, carbon-based chemistry, and energy are all vital components of life.

In 2023, I and other scientists found phosphate, one other life-sustaining compound, in ice grains collected from the ocean of Enceladus. Phosphate, a type of phosphorus, is important for all times for all life on earth. It is a component of DNA, cell membranes and bones. This was the primary time that scientists discovered this compound in an alien water ocean.

Enceladus' rocky core likely interacts with ocean water hydrothermal springs. These hot, geyser-like structures protrude from the ocean floor. Scientists predict that the same environment could have been the birthplace of life on Earth.

Recognize possible life

So far, nobody has discovered life outside Earth. However, scientists agree that Enceladus is a promising place to go looking for all times. So how can we proceed?

An article published in March 2024 states: My colleagues and I conducted a laboratory test It simulated whether dust evaluation instruments on spacecraft could detect and discover traces of life within the ejected ice grains.

To simulate the detection of ice grains as dust analyzers in space record them, we used a laboratory setup on Earth. Using this setup, we injected a tiny jet of water containing bacterial cells right into a vacuum, where the jet broke up into droplets. Each droplet theoretically contained a bacterial cell.

We then fired a laser at the person droplets, producing charged ions from the water and cellular compounds. We measured the charged ions using a way called mass spectrometry. These measurements allowed us to predict what dust evaluation instruments on a spacecraft should find after they encounter a bacterial cell contained in a grain of ice.

We found that these instruments would do a superb job of identifying cellular material. Instruments for analyzing individual ice grains should give you the option to discover bacterial cells, even when an ice grain from an Enceladus-like geyser incorporates only 0.01% of the components of a single cell.

The analyzers could detect a spread of potential signatures from cellular material, including amino acids and fatty acids. Recognized amino acids represent either fragments of the cell's proteins or metabolites, that are small molecules involved in chemical reactions throughout the cell. fatty acids are fragments of lipids that make up cell membranes.

In our experiments we used a bacterium called . The cells on this culture are extremely small – the identical size as cells which may fit into the ice grains released by Enceladus. In addition to their small size, these cells like cold environments and require few nutrients to survive and grow, just like how life would likely be adapted to the conditions in Enceladus' ocean.

The special dust analyzer on Cassini didn’t have the analytical capabilities to discover cellular material within the ice grains. However, scientists are already developing instruments with much greater capabilities for potential future Enceladus missions. Our Experimental results shall be incorporated into the planning and design of those instruments.

Future missions

Enceladus is one among the foremost targets for future NASA and European Space Agency missions. In 2022, NASA announced this a mission to Enceladus had the second highest priority when selecting their next big missions – a Uranus mission was the very best priority.

The European agency recently announced this that Enceladus is the foremost goal of his next big mission. This mission would likely include a high-performance dust analyzer for ice grain evaluation.

Enceladus isn't the one moon with an ocean of liquid water. Jupiter's moon Europa also has an ocean beneath its ice crust that extends across the whole moon. Ice grains on Europa float above the surface, and a few scientists consider Europa may even have geysers like Enceladus that shoot grains into space. Our research may even help study ice grains from Europe.

NASA's Europa Clipper mission will visit Europe in the approaching years. Clipper is scheduled to launch in October 2024 and arrive at Jupiter in April 2030. One of the 2 mass spectrometers on the spacecraft Surface dust analyzeris designed for analyzing individual ice grains.

Our study shows that this instrument will give you the option to search out even tiny fractions of a bacterial cell in the event that they are present in only a number of emitted ice grains.

Given these space agencies' plans for the near future and the outcomes of our study, the prospects for upcoming space missions to Enceladus or Europa are incredibly exciting. We now know that with current and future instruments, scientists should give you the option to search out out whether there’s life on any of those moons.
