NASA’s Voyager 2 probe detects increase in cosmic rays as it approaches the heliosphere

Cosmic rays are fast-moving particles that originate outside the solar system. Some of these cosmic rays are blocked by the heliosphere, so mission planners expect that Voyager 2 will measure an increase in the rate of cosmic rays as it approaches and crosses the boundary of the heliosphere.

NASA’s Voyager 2 Probe Is About To Slip Beyond The Boundaries Of Our Solar System And Into Interstellar Space

Voyager 2 began it’s journey away from Earth back in 1977 and is roughly 11 billion miles from home. In 2007 it entered the outermost layer of the heliosphere, and now based on data recorded by the probe’s Cosmic Ray Subsystem instrument, NASA scientists say there’s a good chance that it is about to reach the boundary (known as the heliopause) and join Voyager 1 in the history books as the second human-made object to go interstellar. Back in August, the cosmic rays hitting the probe increased by five percent.

Cosmic Influence on the Sun-Earth Environment

(Dezember 2008) Since the early days of human civilization we have looked at the sky and tried to understand the environment of the Earth and the Universe [1, 2, 3, 4, and 5]. We are continuously collecting data for different environmental parameters. Sudden heat or cold waves, tornados, erratic rainfall and snowfall are being observed and their forewarning has been attempted. Efforts have been made to understand the influence of stars and the Sun, which, although they are distant objects in space, can influence the environment of the Earth. Extragalactic cosmic rays measured as neutron counting rate, represent an energy spectrum, which is being received by the solar system from the distant stars; the particles of cosmic rays are atom –nuclei with almost light velocity [6, 7]. The effects of the Sun on the environment of the Earth were found to be modulated by the geomagnetic field and the ionizing potential of the cosmic rays [8]. Earth directed Coronal Mass Ejection (CME) and its effects on the thermosphere, ionosphere and atmosphere have been studied. During Earth directed CME a beam of electrons (plasma) is pumped towards the Earth [9]. This beam of electrons is highly conductive and generates an electric field that is transmitted to Earth’s natural plasmosphere and ionosphere. This thin layer of changed electric field further influences the ionosphere and atmosphere of the earth [24]. Since a beam of electrons is carried by an electric current, a magnetic disturbance would be produced. Starbursts are caused by a special variety of neutron star known as a magnetar. These fast-spinning, compact stellar bodies create intense magnetic fields that trigger explosions, which are known as starbursts. Starbursts cause the Sun to develop low Planetary Indices (Kp) and low Electron flux (E-flux) conditions for the Sun-Earth Environment.
If the electron flux from the sun is low, with the subsequent rise in cosmic rays simultaneously anomalous snowfall and lowering of the atmospheric temperature has been observed. It would be possible to understand the movement of clouds and snowfall, as well as atmospheric moisture, if we could efficiently calculate the influence of space weather and cosmic influence on the thermosphere and atmosphere of the Earth [12]. Based on the same hypothesis it was found that an abnormal rise and sudden fall in E-flux, Kp index and atmospheric temperature has the possibility of triggering earthquakes in active fault areas of the Earth due to temporary changes in the magnetic field of the Earth. The whole process was expressed as a precursor of earthquakes in active fault areas.

Ted Cruz calls Trump effort to phase out International Space Station ‚irresponsible‘

Despite his resistance to Trump’s plans for the space station, Cruz has been a supporter of commercializing space efforts since taking over the Commerce Committee panel that deals with NASA.

On Tuesday, he said that efforts to reach Mars can’t only be done with government dollars. Instead, he argued, Washington should fund NASA while also incentivizing the private sector to expand investments in space.

How a Syrian Airstrike Got Help From Space

(24.4.2018) Space electronic warfare Capt. Andrew „Ghost“ Harris and space weapons officer Capt. Ryan „Pippin“ Foster have an urgent task—to make sure the coming allied strike takes full advantage of U.S. satellites in orbit.

“For something of this scale, this is one of—if not the—first time we have had space guys directly involved in the planning, influencing that mission, and developing effects specifically designed to support its execution,” says Morgan. “I’ve been involved in the Air Force for 24 years and I’ve never seen anything like it.”
