California, October 1, 2017 : Pluto’s surface consists of sharp blades of ice that shoot to the height of skyscrapers in Dubai. And scientists now might just be able to tell precisely how these dramatic structures arose.

The revelations of ice on Pluto first altered our understandings in July 2015 when NASA’s New Horizons mission flew past the dwarf planet and sent images of astounding terrains back to earth. Among its numerous discoveries were pictures of strange formations, resembling giant blades of ice, whose origin could not be traced.

Now scientists have come up with a scientific explanation for this ‘knife-like landscape’.

According to data obtained by New Horizons, these structures are made almost entirely of methane ice. While the cause of these peaks is still a mystery, scientists contend that they are likely to arise following a specific kind of disintegration that wore away their surfaces, leaving dramatic peaks and sharp partitions on the planet.

These land edges can be found at the extreme heights on Pluto’s surface, close to its equator and soar as high as the New York skyscrapers. Scientists identify these high cutting blades as a complex feature of the planet’s atmosphere and topographical history.

According to Jeffrey Moore, a research scientist associated with the New Horizons’ mission, presently at NASA’S Ames Research Center in California, the knife-like terrain began with methane solidifying out of the climate at extreme elevations on Pluto. This can be understood to happen in the same manner as frost freezing on Earth, the only difference being in the scale of the two.

These structures can also be found on Earth and are called penitentes. However, here they extend only up to a couple of meters in height in the high-altitude snowfields along the planet’s equator. Researchers believe slight inconsistencies can transform them into dramatic spikes of snow as sunlight sublimates a few sections faster than others and prompting longer and spikier structures.

The discovery of penitentes on Pluto highlights its complex surface and air temperature changes.

The new finding is set to appear in an upcoming issue of the journal Icarus.

NASA is Confident Regarding Mars Opportunity Rover

However, even after the first time engineers hear from Opportunity, it would take time to fully recover, NASA said

There’s reason to be optimistic about Mars Opportunity rover that has been silent since June 10, after getting caught in a massive dust storm on the Red Planet that cut off solar power for the nearly 15-year-old rover, NASA said in a statement.

According to the scientists, the global dust storm is “decaying” — meaning more dust is falling out of the atmosphere than is being raised back into it. As a result, skies might soon clear enough for the solar-powered rover to recharge and attempt to “phone home.”

Studies on the state of batteries and temperatures at the location showed that they were relatively in good health before the storm, and there is not likely to be too much degradation.

Moreover, because dust storms tend to warm the environment — and the storm happened in summer — the rover should have stayed warm enough to survive, the US space agency noted.

Engineers at NASA’s Jet Propulsion Laboratory in California are now looking for signs for recovery efforts.

According to them, Opportunity will need a tau — the veil of dust blowing around — of less than 2.0 before the solar-powered rover will be able to recharge its batteries.

The higher the tau, the less sunlight is available; the last tau measured by Opportunity was 10.8 on June 10. To compare, an average tau for its location on Mars is usually 0.5.

Several times a week, the engineers are using NASA’s Deep Space Network, which communicates between planetary probes and Earth, to attempt to talk with Opportunity.

The massive DSN antennas ping the rover during scheduled “wake-up” times, and then search for signals sent from Opportunity in response.

In addition, JPL’s radio science group uses special equipment on DSN antennas that can detect a wider range of frequencies. Each day, they record any radio signal from Mars over most of the rover’s daylight hours, then search the recordings for Opportunity’s “voice.”

However, even after the first time engineers hear from Opportunity, it would take time to fully recover, NASA said. (IANS)
