Exploring the Galaxy using space probes
This paper investigates the possible use of space probes to explore the Milky Way, as a means both of finding life elsewhere in the Galaxy and as finding an answer to the Fermi paradox. I simulate exploration of the Galaxy by first examining how long time it takes a given number of space probes to explore 40,000 stars in a box from 300 to 300 pc above the Galactic thin disk, as a function of Ga...
متن کاملCompression of Space for Low Visibility Probes
Stimuli briefly flashed just before a saccade are perceived closer to the saccade target, a phenomenon known as perisaccadic compression of space (Ross et al., 1997). More recently, we have demonstrated that brief probes are attracted towards a visual reference when followed by a mask, even in the absence of saccades (Zimmermann et al., 2014a). Here, we ask whether spatial compression depends o...
متن کاملUse of Langmuir probes in non-Maxwellian space plasmas
Disturbance of the Maxwellian plasma may occur in the vicinity of a spacecraft due to photoemission, interactions between the spacecraft and thermospheric gases, or electron emissions from other devices on the spacecraft. Significant non-Maxwellian plasma distributions may also occur in nature as a mixture of ionospheric and magnetospheric plasmas or secondaries produced by photoionization in t...
متن کاملEmissive Probes Emissive Probes
For over 80 years emissive probes have been used to measure plasma potential and a wide variety of methods for interpreting probe data now exists. Constructions, heating methods and measurement techniques are reviewed in detail and their various strengths and limitations are compared. Additionally, several novel uses for emissive probes, such as measuring electron temperature are presented. Thi...
متن کاملRole of ultrasound probes in transmission of hospital infections
Background: The ultrasonography probes are cleaned by absorbent soft, dry cloth. This question arose whether linear and convex ultrasound probes coupling with gel could perform as a means for nosocomial infections transmission, and which method is economical and more efficient for cleaning the probes. This study was conducted to answer these questions. Methods: One hundred – ninety two patients...
