Soyuz Rocket’s Launch-Abort Close Call Highlights Poor Space-Policy Decisions (Op-Ed)

(16.10.2018) One of the cornerstones of the current space policy is to somehow „privatize“ or „commercialize“ the ISS by 2024-2025 and to use the „savings“ from that privatization to help fund the program. The idea of operating the ISS profitably is so preposterous that I don’t feel a need to comment further here. Besides, from where is the funding to come before 2024-2025?

What this look back shows is consistently poor policy decisions going back at least 14 years. What will happen to NASA and U.S. spaceflight in the coming years?

Data From a Dead Satellite Reveals Lost Continents Under Antarctica

The visualization is based on observations from the Gravity field and Ocean Circulation Explorer (GOCE), a European Space Agency (ESA) satellite that operated in orbit from 2009 to 2013. For those four years, the satellite mapped out Earth’s gravity field with unprecedented precision, before it was deliberately destroyed in atmospheric reentry. Since then scientists have combed over its measurements to create maps of Earth’s lithosphere, the tectonically active layer that includes the planet’s crust and outer mantle.

Oddball particles tunneling through Earth could point to new physics

(27.9.2018) However, twice, during its first flight 2006 and its third flight in 2014, ANITA detected odd radio waves with unflipped polarizations coming up from the surface below instead of the horizon. That suggests the signals were produced by upward-zooming air showers triggered by particles that tunneled through Earth. At first blush, that’s not a problem for the standard model. Neutrinos barely interact with matter, so a couple of cosmic neutrinos might have barreled through the planet before smacking an atomic nucleus in the ice and setting off an upward air shower.

With the decrease of solar activity, the magnetic field of oursun is losing power too. This heliosphere shields us forming a gigantic bubble which surrounds and protects our solar system from harmful galactic cosmic rays, these high-energy particles that zip through the universe. Thanks to Voyagers 1 leaving the Solar system, we now have a good vision of it and of its shielding effect. It appears to be an indispensable protection for our fast moving throughout the Universe.

Declining solar activity linked to recent warming

(6.10.2010) An analysis of satellite data challenges the intuitive idea that decreasing solar activity cools Earth, and vice versa. In fact, solar forcing of Earth’s surface climate seems to work the opposite way around — at least during the current Sun cycle. (…)

Contrary to expectations, the net amount of solar energy reaching Earth’s troposphere — the lowest part of the atmosphere — seems to have been larger in 2007 than in 2004, despite the decline in solar activity over that period.

The spectral changes seem to have altered the distribution of ozone molecules above the troposphere.

Whatever they are or wherever they’re from, these particles can be anything between 1018 eV and 1020 eV.

Quite simply, they’re the most energetic particles ever seen in nature.

Wenn ein Treibhausgas baden geht: Wie das Erdmagnetfeld unser Klima beeinflusst

(6.10.2008) Bestätigung für die Theorie, dass das Erdmagnetfeld und die klimatischen Bedingungen zusammenhängen, liefern geo-archäologische und archäomagnetische Studien. So wurde beobachtet, dass in den letzten vier Jahrtausenden vor Christus abrupte Zunahmen des Erdmagnetfelds jeweils mit einer Abkühlung der Temperaturen auf der Erde einhergingen. Zudem wurde ein Zusammenhang zwischen einem stärkeren Erdmagnetfeld und kälteren Perioden seit 700 nach Christus beobachtet.
(…)
Die Ergebnisse zeigten, dass selbst kleine Veränderungen des Magnetfelds die Löslichkeit von Gasen im Wasser verändern. „Wenn das Magnetfeld schwächer war, löste sich 15 Prozent weniger Luft im Wasser als bei einem stärkeren Magnetfeld“, erläutert Winklhofer. „Für Kohlendioxid war der beobachtete Effekt sogar doppelt so stark.“

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.
