NASA Studies High Clouds, Saharan Dust From EPIC View ( Source- Eurasia Review)

Image credits- NASA Source- Eurasia Review From a dusty atmosphere stretching across the Atlantic Ocean to daily views of clouds at sunrise, a new NASA camera keeping a steady eye on the sunlit side of Earth is yielding new insights about our changing planet. With NASA’s Earth Polychromatic Imaging Camera (EPIC), affixed to NOAA’s Deep Space Climate Observatory (DSCOVR) about one million miles from Earth, scientists are getting a new view of our planet’s clouds, land surfaces, aerosols and more. Science results from the first EPIC images were discussed Monday at a media briefing at the American Geophysical Union meeting in San Francisco. EPIC captures a color image of the sunlit side of Earth at least once every two hours, allowing researchers to track features as the planet rotates in the instrument’s field of view. “With EPIC, you see cloud structure from sunrise on the left to sunset on the right,” said Jay Herman, EPIC instrument lead investigator at NASA’s Go

Defining And Regulating The Weaponization Of Space – Analysis ( Source- Eurasia Review / Author- David C. DeFrieze)

Image source- Wikimedia Commons / Credits- NASA Source- Eurasia Review Author- David C. DeFrieze Space is a contested, congested, and competitive domain. Each year the international community relies ever more on space-based technology for defense, civil, and commercial purposes. Accordingly, the weaponization of space has increasingly become an issue of concern. Space is an international common and is thus easier to protect through international cooperation. Since the beginnings of humanity’s venture into space, the international community has made attempts to define and regulate the placement and use of weapons there, but with only limited success. This article discusses the international interest in controlling the weaponization of space and prior attempts to define and regulate it.1 It then offers an approach to better achieve the international cooperation needed to meet global concerns over space weapons. Increasing Reliance on Space The international comm

Space, the Final Frontier Between the Public and Private Sectors ( Source- The National Interest, Author- Paul R. Pillar)

Orbital Sciences Corporation Antares launcher Source- The National Interest Author- Paul R. Pillar Private enterprise that is engaged in transportation to space and the upper atmosphere had two catastrophic failures within the last week: the explosion seconds after liftoff of an Antares rocket launched by Orbital Sciences Corporation under a NASA contract to ferry supplies to the international space station; and the crash, killing one of the test pilots, of a rocket plane that Virgin Galactic hopes to use to give passengers rides through the mesosphere. Accidents can happen to anyone, but the incidents point to some issues regarding the relative roles and performance of the public and private sectors and how those roles are commonly viewed. Two issues in particular. One concerns how a well-founded appreciation for the working of free markets has too often been translated into a crude and unfounded, and ideologically driven, belief that the private sector is inherentl
