... S71-43052 (August 1971) --- A close-up view of a container full of green-colored lunar soil in the Non-Sterile Nitrogen Processing Line (NNPL) in the Lunar Receiving Laboratory (LRL) at the Manned Spacecraft Center (MSC). This sample, broken down into six separate samples after this photo was made, was made up of comprehensive fines from near Spur Crater on the Apennine Front. Astronauts David R. Scott and James B. Irwin took the sample during their second extravehicular activity. ...

. The image is a composite of separate exposures made by the WFC3 instrument on the Hubble Space Telescope. Three filters were used to sample broad wavelength ranges in the near infrared. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: F105W (Y) blue; F125W (J) green; F160W (H) red. NASA/ESA/G. Illingworth/R.

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

... On October 31, 2001 and November 7, 2001 (PST) I took measurements of the guider focus position as a function of the NA2 port rotator angle. ... If the guider focus is a function of the rotator angle, this task becomes much more difficult. ... Our initial data collected during the October observing run appeared to show that we had small variations of the guider focus as a function of rotator angle. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...
