... Fermi bubble due to interstellar migration is introduced in the discussion of galactic signatures. These potential interstellar archaeological signatures are classified using the Kardashev scale. A modified Drake equation is used to evaluate the relative challenges of finding various sources. With few exceptions interstellar archaeological signatures are clouded and beyond current technological capabilities. However SETI for so-called cultural transmissions and ...

... Assembly in its resolution 2777 (XXVI), opened for signature on 29 March 1972, entered into force on 1 September 1972, 94 ratifications, 20 signatures, and 3 acceptances of rights and obligations.

... mapping by MRO’s Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). The spectrometer observations show signatures of hydrated salts at multiple RSL locations, but only when the dark features were relatively ... as extensive, they detected no hydrated salt. Ojha and his co-authors interpret the spectral signatures as caused by hydrated minerals called perchlorates. The hydrated salts most consistent with the chemical ...

... orbited an ancient region of Mars called Nili Fossae. The area revealed the strongest carbonate signature ever found. Although MRO recently detected small patches of carbonates, approximately 200-500 feet wide ... Martian surface, the Mojave study suggests more patches may have been overlooked because their spectral signature could have been changed by the pervasive varnish. "To better determine the extent of carbonate ...

... much more simple. We didn't have all these travel offices and many levels of signature and everything. It was just like that was my job and— '''Butler:''' You needed to ... for was never around. And she knew how to forge his signature just as well as he could write his own signature. So I would take that. In those days, things like ... the last minute people were worried about—somebody had done a study from the radar signatures from their moon and thought that the surface of the moon was twenty feet deep ...

... something came from, and what kinds of events it has experienced, Niles said. This chemical signature suggests that liquid water primarily existed at temperatures near freezing and that hydrothermal systems similar ... carbon dioxide with the heavier oxygen-18. Niles and his team theorize this oxygen isotopic signature indicates liquid water has been present on the Martian surface recently enough and abundantly enough ...

... limits of life, determining the principles that will shape life in the future, and recognizing signatures of life on other worlds and on early Earth. 5.4.2 Conditions for Life ... -MS). The results of these, while still controversial, have determined that neither life nor life signatures were detected. In more than forty years of searching for life within our solar system ... sufficient for the rise of life there. The discovery of fossils or other ancient life signatures would be of great significance to our understanding of the conditions leading to the genesis ...

... data needed to develop spaceborne sensors and software that could recognize missile or reentry vehicle signatures as they flew through or above the atmosphere. To that end, Discovery carried Air Force ... and will serve as a database for missile defense system development. EVA Payload Infrared Background Signature Survey (lBSS); Air Force Program (AFP)-675; Space Test Payload (STP)-I; Multi-Purpose Experiment ...

... WISE could identify blazars. Astronomers often use infrared data to look for the weak heat signatures of cooler objects. Blazars are not cool; they are scorching hot and glow with the ... -energy type of light, called gamma rays. However, they also give off a specific infrared signature when particles in their jets are accelerated to almost the speed of light. One of ... the gamma rays. Sifting through the early WISE catalog, the astronomers looked for the infrared signatures of blazars at the locations of more than 300 gamma-ray sources that remain mysterious ...

... orange book I had shown you. They actually sign off on this. We have their signatures on it that they’ve blessed and approved this plan. This is part of the process, that we get the appropriate signatures that our plan is a valid one. So when we go and we get their signature, we also run through the basics. They want to know, “Okay, can you tell me ...
