CAPE CANAVERAL, Fla. — A NASA spacecraft is ready to set sail for Jupiter and its moon Europa, one of the best bets for finding life beyond Earth.

Europa Clipper will peer beneath the moon’s icy crust where an ocean is thought to be sloshing fairly close to the surface. It won’t search for life, but rather determine whether conditions there could support it. Another mission would be needed to flush out any microorganisms lurking there.

“It’s a chance for us to explore not a world that might have been habitable billions of years ago, but a world that might be habitable today — right now,” said program scientist Curt Niebur.

Its massive solar panels make Clipper the biggest craft built by NASA to investigate another planet. It will take 5 1/2 years to reach Jupiter and will sneak within 16 miles (25 kilometers) of Europa’s surface — considerably closer than any other spacecraft.

Liftoff is targeted for this month aboard SpaceX’s Falcon Heavy rocket from NASA’s Kennedy Space Center. Mission cost: $5.2 billion.

Europa, the superstar among Jupiter’s many moons

One of Jupiter’s 95 known moons, Europa is almost the size of our own moon. It’s encased in an ice sheet estimated to be 10 miles to 15 miles or more (15 kilometers to 24 kilometers) thick. Scientists believe this frozen crust hides an ocean that could be 80 miles (120 kilometers) or more deep. The Hubble Space Telescope has spotted what appear to be geysers erupting from the surface. Discovered by Galileo in 1610, Europa is one of the four so-called Galilean moons of Jupiter, along with Ganymede, Io and Callisto.

Seeking conditions that support life

What type of life might Europa harbor? Besides water, organic compounds are needed for life as we know it, plus an energy source. In Europa’s case that could be thermal vents on the ocean floor. Deputy project scientist Bonnie Buratti imagines any life would be primitive like the bacterial life that originated in Earth’s deep ocean vents. “We will not know from this mission because we can’t see that deep,” she said. Unlike missions to Mars where habitability is one of many questions, Clipper’s sole job is to establish whether the moon could support life in its ocean or possibly in any pockets of water in the ice.

Supersized spacecraft

When its solar wings and antennas are unfurled, Clipper is about the size of a basketball court — more than 100 feet (30 meters) end to end — and weighs nearly 13,000 pounds (6,000 kilograms). The supersized solar panels are needed because of Jupiter’s distance from the sun. The main body — about the size of a camper — is packed with nine science instruments, including radar that will penetrate the ice, cameras that will map virtually the entire moon and tools to tease out the contents of Europa’s surface and tenuous atmosphere. The name hearkens to the swift sailing ships of centuries past.

Circling Jupiter to fly by Europa

The roundabout trip to Jupiter will span 1.8 billion miles (3 billion kilometers). For extra oomph, the spacecraft will swing past Mars early next year and then Earth in late 2026. It arrives at Jupiter in 2030 and begins science work the next year. While orbiting Jupiter, it will cross paths with Europa 49 times. The mission ends in 2034 with a planned crash into Ganymede — Jupiter’s biggest moon and the solar system’s too.

Europa flybys pose huge radiation risk

There’s more radiation around Jupiter than anywhere else in our solar system, besides the sun. Europa passes through Jupiter’s bands of radiation as it orbits the gas giant, making it especially menacing for spacecraft. That’s why Clipper’s electronics are inside a vault with dense aluminum and zinc walls. All this radiation would nix any life on Europa’s surface. But it could break down water molecules and, perhaps, release oxygen all the way down into the ocean that could possibly fuel sea life.

Earlier this year, NASA was in a panic that the spacecraft’s many transistors might not withstand the intense radiation. But after months of analysis, engineers concluded the mission could proceed as planned.

Other visitors to Jupiter and Europa

NASA’s twin Pioneer spacecraft and then two Voyagers swept past Jupiter in the 1970s. The Voyagers provided the first detailed photos of Europa but from quite a distance. NASA’s Galileo spacecraft had repeated flybys of the moon during the 1990s, passing as close as 124 miles (200 kilometers). Still in action around Jupiter, NASA’s Juno spacecraft has added to Europa’s photo album. Arriving at Jupiter a year after Clipper will be the European Space Agency’s Juice spacecraft, launched last year.

Ganymede and other possible ocean worlds

Like Europa, Jupiter’s jumbo moon Ganymede is thought to host an underground ocean. But its frozen shell is much thicker — possibly 100 miles (160 kilometers) thick — making it tougher to probe the environment below. Callisto’s ice sheet may be even thicker, possibly hiding an ocean. Saturn’s moon Enceladus has geysers shooting up, but it’s much farther than Jupiter. Ditto for Saturn’s moon Titan, also suspected of having a subterranean sea. While no ocean worlds have been confirmed beyond our solar system, scientists believe they’re out there — and may even be relatively common.

Messages in a cosmic bottle

Like many robotic explorers before it, Clipper bears messages from Earth. Attached to the electronics vault is a triangular metal plate. On one side is a design labeled “water words” with representations of the word for water in 104 languages. On the opposite side: a poem about the moon by U.S. poet laureate Ada Limon and a silicon chip containing the names of 2.6 million people who signed up to vicariously ride along.

PHNOM PENH, Cambodia — Thirteen pregnant Philippine women accused of illegally acting as surrogate mothers in Cambodia after being recruited online could face prison terms after giving birth, a senior Interior Ministry official said Saturday. 

Interior Ministry Secretary of State Chou Bun Eng, who leads the country’s fight against human trafficking and sexual exploitation, said police found 24 foreign women, 20 Philippine and four Vietnamese, when they raided a villa in Kandal province, near the capital of Phnom Penh, on September 23. 

Thirteen of the Philippine women were found to be pregnant and were charged in court on October 1 under a provision in the law on Suppression of Human Trafficking and Sexual Exploitation, she said. 

The law was updated in 2016 to ban commercial surrogacy after Cambodia became a popular destination for foreigners seeking women to give birth to their children. 

Developing countries have been popular for surrogacy because costs are much lower than in countries such as the United States and Australia, where surrogate services could cost around $150,000. 

The surrogacy business boomed in Cambodia after it was put under tight restrictions in neighboring Thailand, as well as in India and Nepal. 

In July 2017, a Cambodian court sentenced an Australian woman and two Cambodian associates to 1 1/2 years in prison for providing commercial surrogacy services. 

The new case is unusual because surrogates normally are employed in their own countries, not transported elsewhere. 

Cambodia already has a bad reputation for human trafficking, especially in connection with online scams in which foreigners recruited for work under false pretenses are kept in conditions of virtual slavery and help perpetrate criminal fraud online against targets in many countries. 

Details of the new surrogacy case remain murky, and officials have not made clear whether the women were arrested or whether anyone involved in organizing the scheme has been identified. 

Chou Bun Eng told The Associated Press that the business that recruited the surrogates was based in Thailand, and their food and accommodation in Cambodia were arranged from there. She said the authorities had not yet identified the business. 

She said the seven Philippine women and four Vietnamese women who were caught in the raid but who were not pregnant would be deported soon. 

The 13 pregnant women have been placed under care at a hospital in Phnom Penh, said Chou Bun Eng. She added that after they give birth, they could be prosecuted on charges that could land them in prison for two to five years. 

She said that Cambodia considered the women not to have been victimized but rather offenders who conspired with the organizers to act as surrogates and then sell the babies for money. Her assertion could not be verified, as the women could not be contacted, and it is not known if they have lawyers. 

The Philippine Embassy in Cambodia, in response to a local news account of the affair, issued a statement Wednesday confirming most of the details related to what it called the “rescue of 20 Filipino women.” 

“The Philippine Embassy ensured that all 20 Filipinos were interviewed in the presence of an Embassy representative and an interpreter in every step of the investigation process,” it said.

chicago — With a neon-green net in hand, Annette Prince briskly walks a downtown Chicago plaza at dawn, looking left and right as she goes.

It’s not long before she spots a tiny yellow bird sitting on the concrete. It doesn’t fly away, and she quickly nets the bird, gently places it inside a paper bag and labels the bag with the date, time and place.

“This is a Nashville warbler,” said Prince, director of the Chicago Bird Collision Monitors, noting that the bird must have flown into a glass window pane of an adjacent building. “He must only weigh about two pennies. He’s squinting his eyes because his head hurts.”

For rescue groups like the Chicago Bird Collision Monitors, this scene plays out hundreds of times each spring and fall after migrating birds fly into homes, small buildings and sometimes Chicago’s skyscrapers and other hulking buildings.

A stark sign of the risks came last fall, when 1,000 migrating birds died on a single night after flying into the glass exterior of the city’s lakefront convention center, McCormick Place. This fall, the facility unveiled new bird-safe window film on one of its glass buildings along the Lake Michigan shore.

The $1.2 million project installed tiny dots on the exterior of the Lakeside Center building, adorning enough glass to cover two football fields.

Doug Stotz, senior conservation ecologist at the nearby Field Museum, hopes the project will be a success. He estimated that just 20 birds have died after flying into the convention’s center’s glass exterior so far this fall, a hopeful sign.

“We don’t have a lot of data since this just started this fall, but at this point, it looks like it’s made a huge difference,” Stotz said.

But for the birds that collide with Chicago buildings, there is a network of people waiting to help. They also are aiming to educate officials and find solutions to improve building design, lighting and other factors in the massive number of bird collision deaths in Chicago and worldwide.

Prince said she and other volunteers walk the streets downtown to document what they can of the birds that are killed and injured.

“We have the combination of the millions of birds that pass through this area because it’s a major migratory path through the United States, on top of the amount of artificial lighting that we put out at night, which is when these birds are traveling and getting confused and attracted to the amount of glass,” Prince said.

Dead birds are often saved for scientific use, including by Chicago’s Field Museum of Natural History. Rescued birds are taken to local wildlife rehabilitation centers to recover, such as the DuPage Wildlife Conservation Center in suburban Illinois.

On a recent morning, veterinarian Darcy Stephenson at DuPage gave a yellow-bellied sapsucker anesthetic gas before taping its wings open for an X-ray. The bird arrived with a note from a rescue group: “Window collision.”

Examining the results, she found the bird had a broken ulna — a bone in the wing.

The center takes in about 10,000 species of animals annually and 65% of them are avian. Many are victims of window collisions and during peak migration in the fall, several hundred birds can show up in one day.

“The large chunk of these birds do actually survive and make it back into the wild once we’re able to treat them,” said Sarah Reich, head veterinarian at DuPage. “Fractures heal very, very quickly in these guys for shoulder fractures. Soft tissue trauma generally heals pretty well. The challenging cases are going to be the ones where the trauma isn’t as apparent.”

Injured birds go through a process of flight testing, then get a full physical exam by the veterinary staff and are rehabilitated before being set free.

“It’s exciting to be able to get these guys back out into the wild, especially some of those cases that we’re kind of cautiously optimistic about or maybe have an injury that we’ve never treated successfully before,” Reich said, adding that these are the cases “clinic staff get really, really excited about.”
