Asteroid dust could be used to fight climate change on Earth

A group of scientists from Scotland have suggested a unique approach to fighting global warming here on earth. The scientists believe that the answer to global warming on Earth is a giant dust cloud blasted from an asteroid to act as a sunshade for Earth. According to the scientists, a project that reduced the amount of solar radiation the Earth receives by only 1.7% could offset the effects of the global increase in temperature of 3.6°F.

One of the researchers, named Russell Bewick from the University of Strathclyde in Scotland, says that a 1.7% reduction is very small would hardly be noticeable on earth. There are alternatives to using a giant cloud of dust blasted from an asteroid to shield the Earth. Another proposal would place giant mirrors in space, but this plan would be very expensive and require construction in outer space.

NASA – Voyager Celebrates 20-Year-Old Valentine to Solar System

Twenty years ago on February 14, NASA’s Voyager 1 spacecraft had sailed beyond the outermost planet in our solar system and turned its camera inward to snap a series of final images that would be its parting valentine to the string of planets it called home.

six narrow-angle color images were made from the first ever 'portrait' of the solar system taken by Voyager 1

Mercury was too close to the sun to see, Mars showed only a thin crescent of sunlight, and Pluto was too dim, but Voyager was able to capture cameos of Neptune, Uranus, Saturn, Jupiter, Earth and Venus from its unique vantage point. These images, later arranged in a large-scale mosaic, make up the only family portrait of our planets arrayed about the sun.

The Apollo missions in the 1960s and 70s had already altered our perspective of Earth by returning images of our home planet from the moon, but Voyager was providing a completely new perspective, said Ed Stone, Voyager project scientist at the California Institute of Technology in Pasadena.

“It captured the Earth as a speck of light in the vastness of the solar system, which is our local neighborhood in the Milky Way galaxy, in a universe replete with galaxies,” Stone said.

From that first step on the moon, mankind struggles to get that permanent step into space. We have made great strides, the best is yet to come. We need to keep stepping with our advanced technologies as it may be in space where we find resources to repair our damaged planet.

Astronomers Find 6-Pack of Planets in Alien Solar System | LiveScience

Astronomers Find 6-Pack of Planets in Alien Solar System | LiveScience

Astronomers have discovered an alien solar system in which six planets are orbiting a sunlike star, with five of the newfound worlds in close-knit configuration.

Few stars have been observed with planetary arrangements like our solar system, making this a compelling find. The newfound exoplanet system was sighted by astronomers using NASA’s planet-hunting Kepler space observatory.

The smallest of the new alien planets is about 2.3 times the mass of Earth. None of the extrasolar planets are inside the so-called “habitable zone”—– orbits where liquid water could exist on their surfaces, scientists said.

NASA Releasing First Views Of The Entire Sun On Super …

On February 6, the two STEREO spacecrafts will be 180 degrees apart and for the next 8 years the STEREO spacecrafts and SDO will be able to observe the entire 360 degrees of the Sun.

NASA will score big on super SUN-day at 11 a.m. EST, Sunday, Feb. 6, with the release online of the first complete view of the sun’s entire surface …

STEREO (Solar TErrestrial RElations Observatory) is the third mission in NASA’s Solar Terrestrial Probes program (STP). The mission, launched in October 2006, has provided a unique and revolutionary view of the Sun-Earth System. The two nearly identical observatories – one ahead of Earth in its orbit, the other trailing behind – have traced the flow of energy and matter from the Sun to Earth. STEREO has revealed the 3D structure of coronal mass ejections; violent eruptions of matter from the sun that can disrupt satellites and power grids, and help us understand why they happen. STEREO is a key addition to the fleet of space weather detection satellites by providing more accurate alerts for the arrival time of Earth-directed solar ejections with its unique side-viewing perspective.

Founded in 1988, the Space Frontier Foundation is an advocacy organization committed to realizing the vision of a greatly expanded and permanent human presence in space. Space alone offers the resources necessary to ensure the survival and prosperity of our species for numerous generations to come. To realize this vision, the Foundation is fundamentally transforming the conception of space as the exclusive domain of government and government affiliated organizations into a widely accessible frontier ripe with opportunity.�Read about our founding and history.
