NASA Is Seeking Help In Potentially Finding Life On Jupiter’s Moon Europa (Video)

NASA is confident that underneath Jupiter’s moon Europa there could be more water than in our oceans here on Earth. So naturally, Europa has attracted a lot of attention, encouraging the curious to ask, “Could there be life on Europa?”.

Currently, NASA is aiming to send a new mission to Europa by 2025. The White House’s 2015 federal budget allocates $15 million towards making this Europa mission a reality.

Europa has recently become one of NASA’s main focuses because,  out of all the other planetary bodies in our solar system, it has arguably the greatest chance of harboring life.

From Space.com…


“Every 10 years, the U.S. National Research Council, a nonprofit organization that advises the government, issues a report that recommends a planetary exploration strategy for NASA and the National Science Foundation. The current report (which covers 2013 to 2022) ranks an exploration of Europa among the highest priority missions. According to the report, the future mission should focus on taking a closer look at the ocean that scientists suspect lies below the surface; characterizing its icy crust and looking for any subsurface liquid water; determining the surface composition and chemistry; examining surface features and identifying landing areas for future missions; and understanding the purpose of its magnetosphere — the magnetic field surrounding the celestial body. NASA officials said the instrument proposals should focus on at least one of these exploration goals. The announcement calls for instruments designed for a spacecraft that will orbit Europa or complete several flybys, since astronomers do not yet have enough data to pinpoint safe landing sites on the icy moon.”


The video below describes Europa in more detail.

NASA hopes that by providing monetary incentives to private parties, they will encourage competition and innovation, leading to affordable development processes for the instruments necessary for new missions like the upcoming one to Europa.

Two of the main challenges for teams developing instruments are overcoming Jupiter’s high levels of radiation and making sure that no organic material from Earth (like microorganisms, for example) is introduced to Europa’s potentially habitable surface.

The competition ends in April 2015. NASA will select the top 20 proposals, rewarding $25 million to each of the selected teams to further advance their designs for their instruments. NASA will also select eight winners whose instruments will be developed and actually used in NASA’s mission to Europa.

This competition is included in NASA’s budget to get to Europa, according to Space.com…

“NASA is in the process of designing a mission that will cost less than $1 billion and will still meet as many of the exploration goals as possible.”

Blowing the Top Off a Mountain to Build a Telescope So Big It Can See Signs of Life On Other Planets

In a few short weeks, engineers in the Chilean Coastal Ranges of the Andes Mountains in South America will be blowing off the top of Cerro Armazones.  Standing at 10,000 feet, it’s one of the tallest peaks in the region. Here’s Gird Hudepohl, the head engineer for the project:

“We will take about 80ft off the top of the mountain to create a plateau – and when we have done that, we will build the world’s biggest telescope there.”

The Coastal Ranges region is extremely arid, which increases visibility since water vapor in the air obscures a telescope’s vision (this is also why telescopes at high elevations have much better vision than those closer to sea level).

This isn’t Hudepohl’s first rodeo. He works for the European Southern Observatory and was in charge of the demolition of another nearby peak (Cerro Paranal) which is now home to one of the world’s most advanced observatories.

The observatory at Cerro Paranal is equipped with four VLTs (Very Large Telescopes), each the size of “a block of flats” and each equipped with an 8m wide primary mirror (thats more than 24 feet).

Here’s some pictures of the European Southern Observatory (click an image to enlarge):

The new telescope, however, will be bigger than all four of those VLTs combined. The E-ELT (European Extremely Large Telescope- they’re not very creative with the names obviously) will be equipped with a massive 39m (128ft) primary mirror made up 800 segments, each 1.4 meters in diameter but only a few centimeters thick. Each segment must be calibrated with microscopic precision for the telescope to function correctly.

When it’s finished (projected completion is 2025), the telescope will be housed in a 74m (~243ft) dome and weigh in at almost 3,000 tons. The project has a price tag of $1.34 billion.

The telescope is obviously extremely expensive, but the potential benefits it will provide are well worth it. Here’s Cambridge University astronomer Professor Gerry Gilmore explaining why the E-ELT will be such a major breakthrough:

“[Right now] we can see exoplanets but we cannot study them in detail because – from our distant perspective – they appear so close to their parent stars. However, the magnification which the E-ELT will provide will mean we will be able to look at them directly and clearly. In 15 years, we should have a picture of a planet around another star and that picture could show its surface changing colour just as Earth does as the seasons change – indicating that vegetation exists on that world. We will then have found alien life.”

Revolutionary Step? Bolivia Gives the Earth Comprehensive Legal Rights

The Law of Mother Earth is a bold move by the Bolivian government. At its source is the ancient “Pachamama” traditions of the native Andean people. This worldview is based on the belief that the earth is actually a living being (“Pachamama” translates to Mother Earth).

The Bolivian government says the law is a culmination of efforts to combat climate change, to live in harmony with the Earth and to prioritize “the greater good”.

The legislation gives the Earth the rights to,

“Life and regeneration; biodiversity and freedom from genetic modification; pure water; clean air; naturally balanced systems; restoration from the effects of human activity; and freedom from contamination.”

Furthermore, the law decrees that the Bolivian government is now legally bound to,

“Prioritize the well-being of its citizens and the natural world by developing policies that promote sustainability and control industry.”

The economy must operate within the natural limits of the environment, and the government must pursue renewable energy technologies as well as total energy and food sovereignty.

It also gives citizens the right to sue individuals or groups (including the government and businesses) on behalf of the Earth if they belief Earth’s rights have been violated.

Here’s the full list of rights stated in the law:

  • The right to maintain the integrity of life and natural processes.
  • The right to not have cellular structure modified or genetically altered.
  • The right to continue vital cycles and processes free from human alteration.
  • The right to pure water.
  • The right to clean air.
  • The right to balance, to be at equilibrium.
  • The right to be free of toxic and radioactive pollution.
  • The right to not be affected by mega-infrastructure and development projects that affect the balance of ecosystems and the local inhabitant communities

Z-2 Spacesuit: NASA Releases Futuristic Astronaut Suit Design Photos (Photo Gallery)

March 24th NASA released photos and information about a new futuristic suit design known as the “Z-2 Spacesuit”. The suit is one of the most mobile spacesuits ever created and is expected to be used in missions as soon as 2016 according to NASA.

The suit has a functional Buzz Lightyear like appeal and of course is equipped with a life support system. Unlike clothing the suit is not worn but rather entered into from a rear-entry hatch similar to how you’d enter a spacecraft.

Check Out the images of the Z-2 Spacesuit from Space.com.

LOL of the Day: David Attenborough (the Voice of the Planet Earth Series) Narrates Miley’s VMA Spectacle

The increased focus on pop culture is one of my least favorite things about the new digital world, but this video is hilarious. If you’re not familiar, David Attenborough is the soothing British voice behind the vast majority of the BBC’s nature programs including Planet Earth, Life, and Human Planet.

Here is the original video that the narration was taken from about unique avian mating rituals (it’s pretty cool- you should watch!):
