... Heracles Triplane and Aerospace Systems . The key characteristics of two-stage aerospace systems are determined according to speed and carrying capacity of the aircraft-carrier used . ... So the SPIRAL system hypersonic carrier was expected to launch the second stage by weight 63 tons at a speed corresponding to 6M; whereas launching weight of the MAKS system orbital stage with the use of the An-225 MRIYA heavy subsonic aircraft reaches 275 tons, and the HERACLES aircraft - 450 tons. ...

... New technique measures mass of exoplanets . ... Now, scientists at the Massachusetts Institute of Technology (MIT) have developed a new technique for determining the mass of exoplanets using only their transmission spectra dips in light as a planet passes in front of its star. ... To determine the mass of an exoplanet using transmission spectroscopy, de Wit relied on the effect that a planet s mass has on its atmosphere, as transmission spectra give information on a planet s atmospheric properties. ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...
