... Numerous ground-based asteroseismology experiments have failed to produce a definitive signal partly because scintillation in the Earth'satmosphere limits photometric precision. ...
... the time Webb retired just a few months before the first moon landing in July 1969, NASA had launched more than 75 space science missions to study the stars and galaxies, our own Sun and the as-yet unknown environment of space above the Earth'satmosphere ...

... Relatively long integrations are needed, under conditions of minimum dayglow emission from Earth'satmosphere. STIS/CCD 8904 Bias Monitor-Part 2. ...
... Orbiting above the distorting effects of the Earth'satmosphere, the HST provides an unrivaled combination of sensitivity, spectral coverage and angular resolution. ...
... For 0.7z2.0 this line falls in the NIR; a space mission evades the bright infrared glow of the Earth'satmosphere and thus makes this approach possible. ...
... to predict the extreme-UV emission of the early Sun and its consequences for the erosion of the earlyEarth'satmosphere and the altered oxidation state of the planet, and investigate the effect of metallicity on the UV emission and its consequences for ...

... Introduction In principle CCD observations made from above the Earth'satmosphere, and hence free of atmospheric scintillation and transparency variations can provide ultrahigh S/N photometry. ...
