  2. Angular diameter - Wikipedia

    en.wikipedia.org/wiki/Angular_diameter

    Degrees, therefore, are subdivided as follows: 360 degrees (°) in a full circle; 60 arc-minutes (′) in one degree; 60 arc-seconds (″) in one arc-minute; To put this in perspective, the full Moon as viewed from Earth is about 1 ⁄ 2 °, or 30 ′ (or 1800″). The Moon's motion across the sky can be measured in angular size: approximately ...

  3. Astronomical coordinate systems - Wikipedia

    en.wikipedia.org/wiki/Astronomical_coordinate...

    Angles in the hours ( h), minutes ( m), and seconds ( s) of time measure must be converted to decimal degrees or radians before calculations are performed. 1 h = 15°; 1 m = 15′; 1 s = 15″ Angles greater than 360° (2 π ) or less than 0° may need to be reduced to the range 0°−360° (0–2 π ) depending upon the particular calculating ...

    The BIP was at the attachment points between the aeroshell's backshell (also called the afterbody or aft cover) and the cruise ring (also called the cruise stage). SIRCA was also the primary TPS material for the unsuccessful Deep Space 2 (DS/2) Mars impactor probes with their 0.35-meter-base-diameter (1.1 ft) aeroshells. SIRCA is a monolithic ...

  5. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Mean heat flow is 65 mW/m 2 over continental crust and 101 mW/m 2 over oceanic crust. [22] This is 0.087 watt/square metre on average (0.03 percent of solar power absorbed by Earth [ 23 ] ), but is much more concentrated in areas where the lithosphere is thin, such as along mid-ocean ridges (where new oceanic lithosphere is created) and near ...

    In the mid-1960s, to defeat the advantage of the recently introduced computers for the then popular rally racing in the Midwest, competition lag times in a few events were given in centids (1 ⁄ 100 day, 864 seconds, 14.4 minutes), millids (1 ⁄ 1,000 day, 86.4 seconds), and centims (1 ⁄ 100 minute, 0.6 seconds) the latter two looking and ...

    In the IPCC’s 2021 report, scientists estimated that sea level will rise about 0.9 to 3.3 feet (0.28 to 1.01 meters) by 2100, but also said those numbers didn’t factor in uncertainties around ...

    Deep Space 2 project manager Sarah Gavit with the engineering hardware of the probe. Deep Space 2, also known as "Mars Microprobe," [2] was the second spacecraft developed under the NASA New Millennium Program to flight-test advanced technologies concepts for space missions. The purpose of the program was to do high-risk technology ...

  9. Outer space - Wikipedia

    en.wikipedia.org/wiki/Outer_space

    Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
