VIDEO: Mars Simulation Crew Emerges After 365 Days In Isolation


MAUNA LOA (BIVN) – One year after sequestering themselves in a geodesic dome on the slopes of a Hawaii Island volcano, the six crew members of the Mars simulation mission emerged to cheers and media cameras.

Comment:

For 365 days, the Martian-like environment at the 8,200 foot level of Mauna Loa on Hawaii Island served as home for six scientists participating in the fourth University of Hawaii at Manoa Space Exploration and Simulation, or HI-SEAS project.  The exercise was conducted with time delays built in to mimic the distance between Mars and Earth.  Scientists had to wear bulky spacesuits each time they left the specially constructed geodesic dome they called home.  As in previous HI-SEAS projects, the research focused on crew member cohesion and performance.

Success for Juno’s 1st Jupiter flyby | Space | EarthSky


Juno spacecraft arrived at Jupiter on July 4 and has spent some weeks in a testing mode. On Saturday, it came closer to Jupiter than any spacecraft ever has.

Comment:

On Saturday, 27 August 2016, the Juno spacecraft snapped this image of the giant planet Jupiter as the space probe completed its closest approach to the gas giant.  Juno skipped through intense radiation belts only 2,600 miles /4,200 km above the planet’s surface. There was no reported damage to Juno’s experiments or instruments after the 30-minute swing through the radiation belts.  There will be 35 more flybys during the Juno mission, which ends in February 2018.

Are biofuels worse for the planet than gasoline? – CSMonitor.com


A new study suggests that biofuels can mitigate only 37 percent of the CO2 released by burning the biofuel.

Comment:

The debate between supporters of corn-based biofuels and environmentalists has been ongoing for years.  A new study from the University of Michigan Energy Institute is turning up the heat again.

According to lead researcher John DeCicco, corn ethanol and biodiesal fuels may damage the environment more than petroleum-based gasoline.

DeCicco says the “aggregate U.S. crop yield can remove only 37 percent of the CO2 that burning biofuels releases into the air.”

However, Harvard geologist David Schrag believes that premise is “flawed”, adding that “biofuels don’t have to be carbon neutral to be an environmentally preferable alternative to petroleum gasoline.”  Schrag recommends the planting of forests to sequester more CO2, because “forests are better than cornfields in recovering CO2 from the air.”

Opinion:

Perhaps this contentious debate will be resolved when electric cars are developed to the point where they can compete with fossil-fueled cars in terms of range, price, and charging ability.  The transition to electric vehicles is underway, but more charging stations and higher capacity batteries are needed before we can phase out fossil fuels.

On Friday, 26 August 2016, President Barack Obama will create the world’s largest protected marine sanctuary by extending the boundaries of the Papahanaumokuakea Marine National Monument.  The new boundaries will enclose 582,578 square miles of ocean and land in an area known as the Northwest Hawaiian Islands.  The protected sanctuary will be off-limits to commercial or tourist ventures.  Scientific and cultural studies will be permitted along the 1,200 mile chain of islands, sandbars, and exposed rocks.

Comment:

We may not have to voyage too far to find a planet that resembles Earth. According to a report released by a panel of scientists, researchers, and astronomers, data collected over many years have confirmed the existence of a rocky planet, named Proxima b, orbiting the red dwarf star Proxima Centauri, about 4.2 light years from Earth.

Scientists say the small planet is within the so-called “habitable zone” of its host star, “meaning liquid water could exist on the surface…it may also be the closest possible home for life outside our solar system.”

Because of Proxima b’s relative closeness, it could be explored robotically in the centuries ahead.  If the planet can support life as we know it, Proxima b may be earmarked as a future home for Earth’s population as our Sun ages and becomes a red giant star.

Scientists believe the good news is that Proxima b is so close, and is perhaps the only favorable planet within our technological grasp.

Red dwarf stars, such as Proxima Centauri, are long-lived and could support an Earth like evolutionary cycle–time long enough to develop the variety of life we know today.

Bill Nye: Climate change to blame for Louisiana floods – CNN.com

Comment:

Television science personality Bill Nye tells CNN’s “New Day” program that climate change is the cause of devastating floods that have inundated 60,000 homes and taken 13 lives in Louisiana.  Based on the evidence he’s seen, Louisiana is looking to years of heavy rains, flooding, and soil erosion from more frequently occurring storm systems created by warming ocean conditions.

Nye believes these newer storms will produce “catastrophic floods” and eventually lead to economic and social dislocation as Louisiana residents move away from flood-prone areas.  Louisiana is headed for some very rough times, and there is little we can do about it.
