Teacher: Now, understand the problem? Solve this instance: Astronomers know that interstellar water is abundantly available to young planetary systems—our blue planet collected (or accreted) plenty of it. Still, the details of water's movement in the inner solar system are elusive. Sarafian et al. measured water isotopes in meteorite samples from the asteroid Vesta for clues to the timing of water accretion. Their samples have the same isotopic fingerprint of volatiles as both Earth and carbonaceous chondrites, some of the most primitive meteorites. The findings suggest that Earth received most of its water relatively early from chondrite-like bodies. 
  
 Abstract 
  
 Determining the origin of water and the timing of its accretion within the inner solar system is important for understanding the dynamics of planet formation. The timing of water accretion to the inner solar system also has implications for how and when life emerged on Earth. We report in situ measurements of the hydrogen isotopic composition of the mineral apatite in eucrite meteorites, whose parent body is the main-belt asteroid 4 Vesta. These measurements sample one of the oldest hydrogen reservoirs in the solar system and show that Vesta contains the same hydrogen isotopic composition as that of carbonaceous chondrites. Taking into account the old ages of eucrite meteorites and their similarity to Earth’s isotopic ratios of hydrogen, carbon, and nitrogen, we demonstrate that these volatiles could have been added early to Earth, rather than gained during a late accretion event. ||||| With its distinctive reddish and white stripes, its gracefully flowing fins, and its menacing spine, not many fish can embody the beauty, mystery, and danger of the ocean quite like the lionfish. Although it's native to the Indo-Pacific region, lionfish were introduced to the Atlantic and are now found along the U.S. coast, from North Carolina to Florida, and in the Bahamas and Caribbean. The lionfish spells trouble for the balance of ecosystems and fisheries it invades, as it can out-compete native species for food and space. It lacks predators, has a voracious appetite, reproduces quicly, and is spreading fast.

 Analysis of meteorites from the mini-planet Vesta, located in the main asteroid belt between Jupiter and Mars, show hydrogen isotope ratios that match what has been found in ancient, unaltered meteorites known as carbonaceous chrondrites. 
  
 ANALYSIS: Extreme Earth Life Can Aid Search for Alien Lifeforms 
  
 Scientists already had a match between the chemical fingerprints of Earth’s hydrogen and the carbonaceous chrondites, but what they didn’t know is when the water would have been available to accrete into Earth. 
  
 The new analysis pushes water’s first appearance in Vesta and presumably on other rocky, planet-like bodies including Earth to just 14 million years after the start of the solar system. 
  
 “All the the planets could have gotten their water very early, which means the planets could have been habitable immediately after they formed. They weren’t just sitting there and looking at their watch, waiting for water to come,” Adam Sarafian, a geophysics doctorate student at the Woods Hole Oceanographic Institution in Massachusetts, told Discovery News. 
  
 ANALYSIS: Has Earth Splattered Life All Over the Solar System? 
  
 Water is necessary for life as we know it. 
  
 Geologic activity on Earth has destroyed the earliest records of the planet’s formation, with its oldest rocks dating back to about 200 million years after the formation of the solar system some 4.6 billion years ago. 
  
 Analysis of rocks from the moon, retrieved during the 1969-1972 Apollo missions, show water was available in the inner solar system about 150 million years after the solar system’s formation. 
  
 NEWS: Did Life on Earth Come From Mars? 
  
 The Vesta meteorites, known as eukrites, date back to 14 million years after the start of the solar system. Sarafian and collegues measured a mineral called apatite in the samples to determine their water content. 
  
 “This is the oldest water that anyone has measured that has accreted to something that resembles a planet,” Sarafian said. ||||| An illustration of the early solar system shows proto-Earth, proto-Mars, Vesta within the asteroid belt, and proto-Jupiter. The dashed white line represents the "snow line" boundary for water ice in the solar system. 
  
 The water that supports life on Earth may have been on the planet much earlier than scientists previously thought, new research suggests. 
  
 While the environmental conditions in Earth's early years made it impossible for water to remain on the planet's surface, scientists have found evidence that the ingredients for water were protectively stored inside rocky bodies near our planet — and maybe inside Earth itself. The new findings suggest that there was water in the inner solar system 135 million years earlier than previous evidence had shown. 
  
 "Our findings show the earliest evidence of water in the inner solar system," said Adam Sarafian, a Ph.D. student at the MIT/Woods Hole Oceanographic Institution in Massachusetts and lead author of the new study. [Our Solar System: A Tour of the Planets] 
  
 The smoking gun appears inside meteorites that once belonged to the asteroid Vesta, one of the largest members of the asteroid belt that sits between Jupiter and Mars. Meteorites from Vesta —dark chunks of cooled magma often as big as grapefruits — continue to be found in Antarctica. Previous analysis found no water or water-forming ingredients in those meteorites. But Sarafian and his colleagues zoomed in on the molecular contents of the meteorites, and found trace amounts of hydrogen-oxygen molecules. 
  
 More than 4.5 billion years ago — or about 15 million years after solid bodies began to form around the young sun — water existed in the outer, cooler parts of the solar system, previous studies have shown. But in the inner solar system, where Vesta and a young Earth resided, temperatures were far too hot and solar winds would send any water vapor to the outer regions of the solar system. 
  
 While the Earth grew and changed over the next 4 billion years or so, Vesta remained frozen in time, according to Sarafian. 
  
 "Vesta gives us a snapshot of what Earth maybe looked like when it was first forming," Sarafian said.

 Vesta also has the same chemical fingerprint as the Earth. In other words, scientists have previously shown that the nitrogen on Vesta likely originated from the same source as the nitrogen on Earth. Some bodies in the solar system, like the sun or comets, have different chemical signatures. According to Sarafian, the new study shows that Vesta and Earth also share a hydrogen chemical signature. 
  
 The Earth also shares a chemical fingerprint with the moon, which, like Vesta, gives scientists a window to the past. Scientists have found traces of water in lunar rocks, which provides evidence that the life-giving liquid was in the inner solar system as early as 150 million years after the birth of the solar system. The Vesta samples predate the lunar samples by 135 million years. 
  
 The jump back in time is significant, says Sarafian, because during those first 150 million years, the inner solar system was considerably hotter and more hostile than it was later on. Earth would have experienced major impacts from flying debris (it was potentially such an impact that broke off a portion of the Earth and formed the moon). Many scientists have suspect that through those big impacts and high temperatures, it would make sense for the hydrogen to turn into vapor and be blown out into space. 
  
 "The planets held on to the water somehow," Sarafian said. "That's going to make people rethink how planets are made." 
  
 Sarafian said the work supports the view that the water came from icy bodies near Jupiter. The newly forming gas giant likely flung the chunks of rock and ice inward. Jupiter would have been located beyond what's known as the "snow line," or the point beyond which temperatures were cool enough for water to condense into liquid or solid form, he said. 
  
 "There are models that predict that icy bodies from the outer solar system, around the Jupiter area, probably got flung into the inner solar system," Sarafian said. "But there was just no evidence for it. There wasn't any data to support the model. And our study is supporting it." 
  
 Jeremy Boyce, a geochemist at UCLA who was not involved in the new study but has collaborated with two of the study's authors on other works, said the new study's claims of water in the early inner solar system are robust. But he added that it's still unclear just how much water was present. It's likely that to make the oceans present on Earth today, more water was delivered to Earth later in its life. 
  
 "The extent to which [the early water] relates to water we see on the surface of the Earth is an open question," said Boyce. "What water was present in the early Earth and what arrived later — I don't think we know that yet." 
  
 The new study is detailed in the Oct. 31 issue of the journal Science.

Student:
At least when it comes to life as we know it, water is a basic requirement. So a new analysis of meteorites suggesting that water could have appeared on Earth 14 million years after the start of solar system some 4.6 billion years ago—more than a hundred million years earlier than previously thought—also raises the possibility that life began on Earth earlier as well. And the same could be said of other planets. "All the planets could have gotten their water very early, which means the planets could have been habitable immediately after they formed," a study author tells Discovery. Says another author to National Geographic, "The other inner planets could have been wet early and evolved life before they became the harsh environments they are today." Researchers at the Woods Hole Oceanographic Institution came to their conclusion, published in Science, by analyzing meteorites from Vesta. The asteroid lies in the main asteroid belt between Jupiter and Mars, and meteorites from it have been found in Antarctica. Vesta and Earth formed in the inner solar system, and scientists have already determined that Vesta's nitrogen likely came from the same source as our own. Past analysis of the meteorites didn't turn up any water, but as Space.com puts it, the researchers "zoomed in on the molecular contents of the meteorites, and found trace amounts of hydrogen-oxygen molecules." Vesta's meteorites date to 14 million years after the solar system's start, offering proof that there was water in the inner solar system at that point. (A study in Science last month finds water to be more than 4.5 billion years old.)
