ipedia.com: Airy-0 crater Article Airy crater was named in honor of the British Astronomer Royal Sir George Biddell Airy (1801-1892), who in 1850 built the "transit circle" telescope at Greenwich. Airy-0 is about 0.5 kilometers across and lies within the larger Airy crater in the region Sinus Meridiani.

CONK! Encyclopedia: Prime_Meridian The prime meridian of Mars is defined by the crater Airy-0. The prime meridian of the Moon lies directly in the middle of the face of the moon visible from earth and passes near the crater Bruce.

George Airy Biography Airy's discovery of a new inequality in the motions of Venus and the earth is in some respects his most remarkable achievement. In 1872 Airy conceived the idea of treating the lunar theory in a new way, and at the age of seventy-one he embarked on the prodigious toil which this scheme entailed. He was born at Alnwick, one of a long line of Airys who traced their descent back to a family of the same name residing at Kentmere, in Westmorland, in the 14th century. www.biographybase.com /biography/Airy_George.html   (1633 words)

ESA - Mars Express - Where is zero degrees longitude on Mars? A crater in the Sinus Meridiani was later called Airy, named to commemorate the builder of the Greenwich transit. Merton Davies of the RAND Corporation was analysing surface features and designated a 0.5-kilometre-wide crater, subsequently named 'Airy-0' (within the larger crater Airy) as the zero point. The US Mars Global Surveyor (MGS) attempted to take a picture of Airy-0 on every close overflight it made since the beginning of its mapping mission. www.esa.int /export/SPECIALS/Mars_Express/SEM0VQV4QWD_2.html   (550 words)

Mars Global Surveyor MOC2-273 Release Davies designated a 0.5-kilometer-wide crater (0.3 miles wide), subsequently named "Airy-0" (within the large crater Airy in Sinus Meridiani) as the longitude zero point. The transit circle was built by Sir George Biddell Airy, the 7th Astronomer Royal, in 1850.

Technical Notes on Mars Solar Time The prime meridian of Mars is defined by the location of the crater Airy-0 (De Vaucoulers et al., 1973), named in honor of the British astronomer who built the telescope at Greenwich whose location defines the prime meridian on Earth. Although it might be tempting to refer to "standard" time on the Mars prime meridian as "Airy Mean Time" (AMT) in analogy to Earth's "Greenwich Mean Time" (GMT), the latter term has been supplanted by Coordinated Universal Time (UTC) in international timekeeping services. The error in the currently coded conversion between TT and UTC is itself in error for some periods in the post-1975 era by as much as 3sec. www.giss.nasa.gov /tools/mars24/help/notes.html   (2462 words)

microsoft accounting software dublin ohio - 1st accounting The Mars Sol Date is defined mathematically as MSD = (Julian date using International Atomic Time - 51549.0 + k)/1.02749125 + 44796.0, where k is a small correction of approximately 0.00014d (or 12sec) due to uncertainty in the exact geographical position of the prime meridian at Airy-0 crater. Mars has a prime meridian, defined as passing through the small crater Airy-0. Around sunset and sunrise the Martian sky is pinkish-red in color, but in the vicinity of the setting sun it is blue. accounting.valenuti.info /dir16/microsoft-accounting-software-dublin-ohio.html   (454 words)

Re: How was zero meridian deturmined for the planet Mars. The prime meridian is defined to pass through the center of a particular crater, Airy-0. All other things being equal, it must pass through the north and south poles, so the meridian is defined. www.madsci.org /posts/archives/1999-09/937162647.As.r.html   (133 words)

psychotherapy & employee assistance programs - 3rd psychology The Mars Sol Date is defined mathematically as MSD = (Julian date using International Atomic Time - 51549.0 + k)/1.02749125 + 44796.0, where k is a small correction of approximately 0.00014d (or 12sec) due to uncertainty in the exact geographical position of the prime meridian at Airy-0 crater. There are also transits of Mercury and transits of Venus, and the moon Deimos is of sufficiently small angular diameter that its partial "eclipses" of the Sun are best considered transits (see Transit of Deimos from Mars). Mars is also scarred by a number of impact craters. psychology.vollotin.info /dir17/psychotherapy-&-employee-assistance-programs.html   (870 words)
