Presence of Methane on Pluto confirmed: NASA

Pluto_for_wikiWashington: NASA’s New Horizon probe — set for a Pluto flyby on July 14 — has confirmed that there is frozen methane on Pluto’s surface.

The Earth-based astronomers first observed Methane on Pluto in 1976.

“We already knew there was methane on Pluto but these are our first detections,” said Will Grundy, team leader with the Lowell Observatory in Flagstaff, Arizona.

Soon, we will know if there are differences in the presence of methane ice from one part of Pluto to another, he added in a statement.

New Horizons is now about 16 million km from the Pluto system – around 4.75 billion km from the Earth.

Methane was detected by a team of ground-based astronomers led by New Horizons team member, Dale Cruikshank of NASA’s Ames Research Center, Mountain View, California.

The detection was made possible with the help of  the infrared spectrometer on New Horizons spacecraft.

Methane is an odourless, colourless gas that is present underground and in the atmosphere on the Earth.

On Pluto, methane may be primordial, inherited from the solar nebula from which the solar system formed 4.5 billion years ago.

Just hours after its flyby of Pluto on July 14, the spacecraft will observe sunlight passing through the planet’s atmosphere, to help scientists determine the atmosphere’s composition.

“It will be as if Pluto were illuminated from behind by a trillion-watt light bulb,” noted New Horizons scientist, Randy Gladstone.

The spacecraft is healthy and all systems are operating normally.

“We are really on the final path. It just gets better and more exciting every day,” said project manager Glen Fountain. (IANS)

NASA Explore Technology To Build Future Homes Made of Fungi For Moon, Mars

Upon arrival, by unfolding that basic structure and simply adding water, the fungi will be able to grow around that framework into a fully functional human habitat

Instead of habitats made of metal and glass, NASA is exploring technologies that could grow structures out of fungi to become our future homes in the stars, and perhaps lead to more sustainable ways of living on Earth as well.

Creating a livable home for future astronauts means doing more than growing a roof to go over their heads. Astronauts will need to have all their basic needs met, just like on Earth, and face the additional challenges of living in a harsh environment on a distant world, the US space agency said in a statement.

Keeping that in mind, the myco-architecture project out of NASA’s Ames Research Center in California is prototyping technologies that could “grow” habitats on the Moon, Mars and beyond out of life – specifically, fungi and the unseen underground threads that make up the main part of the fungus, known as mycelia.

“Right now, traditional habitat designs for Mars are like a turtle – carrying our homes with us on our backs – a reliable plan, but with huge energy costs,” said Lynn Rothschild, the principal investigator on the early-stage project.

“Instead, we can harness mycelia (vegetative part of a fungus) to grow these habitats ourselves when we get there”. Ultimately, the project envisions a future where human explorers can bring a compact habitat built out of a lightweight material with dormant fungi that will last on long journeys to places like Mars.

Upon arrival, by unfolding that basic structure and simply adding water, the fungi will be able to grow around that framework into a fully functional human habitat – all while being safely contained within the habitat to avoid contaminating the Martian environment.

Mycelia are tiny threads that build complex structures with extreme precision, networking out into larger structures like mushrooms.
With the right conditions, they can be coaxed into making new structures – ranging from a material similar to leather to the building blocks for a Mars habitat.

That last layer of mycelia is what organically grows into a sturdy home, first activated to grow in a contained environment and then baked to kill the lifeforms – providing structural integrity and ensuring no life contaminates Mars and any microbial life that’s already there. Even if some mycelia somehow escaped, they will be genetically altered to be incapable of surviving outside the habitat, said NASA.

Mycelia could also be used for water filtration and biomining systems that can extract minerals from wastewater – another project active in Rothschild’s lab – as well as bioluminescent lighting, humidity regulation and even self-generating habitats capable of healing themselves. And with about 40% of carbon emissions on Earth coming from construction, there’s an ever-increasing need for sustainable and affordable housing here as well.

The harsh environments of the Moon and Mars will require new ways of living – growing homes instead of building them, mining minerals from sewage instead of rock. “But by turning to the elegant systems of our own natural world, we can design solutions that are green and sustainable. Whether on distant worlds or our own ever-changing Earth, fungi could be what brings us boldly into the future,” said NASA. (IANS)
