NASA Releases Most Detailed Map Of The Oceans Yet

The bottom of the ocean is a mysterious place. We probably know the surface of Mars better than areas in the Atlantic and the Pacific. But we now have our best look at the seafloor yet, thanks to the NASA Earth Observatory.

The researchers looked at gravitational anomalies to produce a detailed analysis of underwater features, and by doing this were able to spot anythinglarger than 5 kilometers (3 miles).

The paper was published in Science last year, and the data was used to create small maps that are even available on Google Earth. Themap gives the first comprehensive look at the entire data set showing the diversity and complexity of the depths of Earths oceans.

Traditionally, ocean floor maps are made using sonar. However, ships are small compared to the big blue sea, and this kind of technique is only good for limited portions of the seabed. It is expensive and time consuming, and it isbelievedthis is why only about 5 percentof the ocean floors have been explored.

Instead, the team behind the new research used satellites to precisely measure the gravitational field of our planet. An underwater mountain would have a slightly stronger pull (appearing red in the map),and a submarine canyon would have a weaker gravitational field (blue in the map).

This technique has already been employed to look at another invisible area of the planet; by measuring gravity, researchers were able to observe the geological formations present in Antarctica beneath the thick sheet of ice.

The measurements were taken by the NASA-CNES Jason-1 satellite as well as using ESAs CryoSat-2 and data from missions in the 1980s and ’90s. The data was combined through computer analysis and the map released by the NASA Earth Observatory is the most extensive map of the ocean floor ever made.

This map will further improve our understanding of plate tectonics and evolution of the ocean, as well as giving targets for more precise sonar investigations.

Europa Might Be Hotter That Previously Thought

When looking for life outside Earth, Jupiter’s moon Europa, with its hypothesized underground ocean, is one of thestrongest candidates in the Solar System. Understanding this fascinating moon could prepare us for future missions there, so scientists are carefully looking at how Europa might have gotten its ocean.

One issue to be considered is how this ocean was kept as a liquid, but a team of astronomers from the U.S. has now suggested that Jupiter’s gravitational attraction has more of a heating effect than thought.Their prediction is an order of magnitude larger than previous estimates, and it better models the condition this (and maybe other) natural satellitesgothrough.

The results, published inEarth and Planetary Science Letters, focused on the ice grains found on Europa. The researchers ranexperiments to recreate the conditions the ice is subjected to, and they discovered that the main source of heat comes from defects in the crystal ice structure, which affects how heat is actually dissipated across the ice shell.

The beauty of this is that once we get the physics right, it becomes wonderfully extrapolative, said co-author Reid Cooper from Brown University in astatement.

Those physics are first order in understanding the thickness of Europas shell. In turn, the thickness of the shell relative to the bulk chemistry of the moon is important in understanding the chemistry of that ocean. And if youre looking for life, then the chemistry of the ocean is a big deal.

The first indication of Europa being an active world came from images taken by theVoyager probesin 1979. The satellite was notthe smooth, icy ball that was expected, but was instead striped and cracked.

Europa is the sixth moon of Jupiter and orbits the planet in just over three days. It is tidally locked with Jupiter, meaning one face always points towards the gas giant,and it is in orbital resonance with two other moons, Io and Ganymede. The three moons’ periods arewhole integerratios of each other. That is to say, Ganymede’srevolution is twice as long as Europas, which is twice as long as Ios.

This combination of celestial mechanics, added tothe size of Jupiter, stretches and compresses the moons. Io has active volcanoes, and Europa and Ganymede,potentially,liquid oceans.

[Scientists] had expected to see cold, dead places, but right away they were blown away by their striking surfaces, said Christine McCarthy, lead author of the research, in the statement.

There was clearly some sort of tectonic activity things moving around and cracking. There were also places on Europa that look like melt-through or mushy ice.

The only way to have tectonics is through heat, and the only way to have heat in such a small object far away from the Sun is through gravitational force. Perhaps this research will bring us closer to understanding just how Europa’s ocean is maintained.

CIA Declassifies Amazing 1972 Spy Satellite Capsule Deep-Sea Rescue

Cia-declassifies-amazing-1972-spy-satellite-capsule-deep-sea-rescue-885b522c12

It’s a plot worthy of a Hollywood action movie: 40 years ago, the U.S. Navy carried out a daring mission to retrieve a top-secret film capsule that had settled more than 16,000 feet underwater on the ocean floor. At the time, the expedition was the deepest undersea salvage operation ever attempted.

Documents released publicly by the Central Intelligence Agency on Aug. 8 detail the capsule’s incredible recovery, using what was at the time the Navy’s most sophisticated deep-sea submersible.

On July 10, 1971, a classified U.S. satellite, code-named Hexagon, attempted to return a mysterious “data package” to Earth by ejecting a capsule over the Pacific Ocean. The capsule’s parachute failed, and the canister slammed into the water with an excruciating 2,600 Gs of force.

Hexagon satellites, which were declassified in 2011, were photoreconnaissance spacecraft that were part of an American Cold War-era spy program. Since these satellites preceded today’s era of digital technology, Hexagons recorded images on film, sending them back to Earth in capsules that re-entered Earth’s atmosphere and landed within a designated zone near the Hawaiian Islands in the Pacific Ocean.

During the first Hexagon mission in the summer of 1971, a parachute carrying one of these capsules broke, and the precious cargo crashed into the ocean and sunk about 16,400 feet.

To recover the sunken capsule, the U.S. Navy crafted a bold rescue mission that would be carried out by its Trieste II Deep Sea Vehicle, or DSV-1. At the time, this mini-submarine was the Navy’s best deep-sea submersible.

(SPACE.com)

The newly declassified CIA documents include a report of the undersea mission and pictures of the Navy’s DSV-1 and the film capsule at the bottom of the ocean. The report, which offers a glimpse of the exhilarating events, also explains how and why the CIA decided to retrieve the Hexagon Recovery Vehicle (RV) in the first place.

“The decision was made to attempt the deep sea recovery of the RV primarily for the intelligence value of the film record and secondly to establish a capability for deep oceanographic recovery,” intelligence officials wrote.

According to the documents, the Trieste II made three attempts to salvage the film capsule: first on Nov. 3, 1971, then on Nov. 30, 1971, and finally, in a successful third try, on April 25, 1972.

The mission’s planners had four primary areas of concern, beginning with the ability to pinpoint the impact area. At that time, no object the size of the film canister had been detected by sonar and been searched for underwater. Officials were also unsure how much damage the capsule had suffered upon impact, and after being submerged in sea water. Finally, the Trieste II had yet to venture below 10,000 feet before then.

These obstacles were eventually overcome, and on its third attempt, the Trieste II found its sunken treasure. In the predawn hours of April 26, 1972, the Trieste II emerged about 350 miles (563 kilometers) north of the Hawaiian Islands with the remains of the Hexagon film capsule.

“The third attempt was successful in locating and securing the film stacks; however, as the Trieste was surfacing, the film broke into pieces,” officials wrote in their report. “Twenty-five feet was recovered.”

The film stack underwent extensive analysis, and it was determined that the Hexagon’s Recovery Vehicle broke apart as it crashed into the water. The spools of film were separated from the capsule and several pieces were cut and floated away.

But, all was not lost. The mission proved to be a valuable test of the Navy’s ability to carry out deep-sea recovery expeditions. In the report, CIA officials discussed some of the lessons learned, particularly from setbacks that were experienced on all three attempts.

“The third dive, the mechanical arm failed to work, almost preventing operation of the recovery device,” the report said. “The on-board computer has never worked. Much more attention is required to the use of high reliability parts and extensive subsystem testing to assure confidence in any given operation.”

Still, the mission was seen as a success, even as the motivation for the capsule’s recovery shifted from the potential value of the film’s reconnaissance, to the usefulness of testing the capabilities of the Trieste II submersible.

“All of the men involved remained enthusiastic and determined throughout the many frustrations and are to be commended for their fine efforts,” the report concluded.
