IM-1 (Odysseus) in preparation for launch

IM-1 was a robotic Moon landing mission conducted by Intuitive Machines (IM) in February 2024 using a Nova-C lunar lander. After contact with the lunar surface on February 22 the lander tipped to an unplanned 30 degree angle. All instrument payloads remained functional and the mission was deemed a success.[1] IM-1 was the first commercial mission to successfully soft-land on the Moon.[2][3] NASA provided funding support for the mission through the Commercial Lunar Payload Services program. The lander, named Odysseus, carried six NASA-developed payloads and several others from commercial and educational customers. On February 29, Odysseus lost power and shut down with the start of the lunar night.[4]

IM-1 was the first soft lunar landing by a private company[5][6] and Odysseus was the first American-made spacecraft to soft-land on the Moon since Apollo 17 in 1972. Steve Altemus, CEO of IM, says Nova-C is the first spacecraft to use liquid methane and liquid oxygen (methalox) propulsion beyond low-Earth orbit, and also the first methalox spacecraft to land on an off-world celestial body.[7]

The Intuitive Machines Nova-C, or simply Nova-C, is a class of lunar landers designed by Intuitive Machines (IM) to deliver small payloads to the surface of the Moon. Intuitive Machines was one of three service providers awarded task orders in 2019 for delivery of NASA science payloads to the Moon.[11] The IM-1 lunar lander, named Odysseus (pronounced /əˈdɪsiəs/ ə-DISS-ee-əs), was launched by a SpaceX Falcon 9[9] rocket on 15 February 2024, reached lunar orbit on 21 February, and landed on the lunar surface on 22 February. This marked the inaugural Nova-C landing on the Moon and the first American spacecraft to perform a soft landing on the Moon in over 50 years.[12][13] It is the first spacecraft to use methalox propulsion to navigate between the Earth and the Moon.

The second Nova-C lander with the IM-2 mission is scheduled to launch no earlier than January 2025,[10] and a third Nova-C lander on the IM-3 mission is scheduled for no earlier than October 2025.[14] SpaceX is under contract to provide Falcon 9 launches for each of the three landers.[15][16][17][18]

Marriage

edit

Definition

edit

The fundamental nature of marriage is the subject of philosophical debate: constructionists view marriage as a social construct created, institutionalized, and sometimes modified by humans; essentialists hold the dialectically opposed view that the essence of marriage is not something humans — individually or as a society — can change.

Not a prerequisite for children

edit

Marriage has never[19] been a prerequisite for having children.

In some cultures marriage imposes upon women the obligation to bear children. In northern Ghana, for example, payment of bridewealth signifies a woman's requirement to bear children, and women using birth control face substantial threats of physical abuse and reprisals.[20]

Marriage and cohabitation

edit

In the U.S., married people usually live together in the same home, often sharing the same bed,[21] but in some other places this is not the tradition. In southwestern China, walking marriages, in which the husband and wife do not live together, have been a traditional part of the Mosuo culture.[22] Walking marriages have also been increasingly common in modern Beijing. Guo Jianmei, director of the center for women's studies at Beijing University, told a Newsday correspondent, "Walking marriages reflect sweeping changes in Chinese society."[23] A similar arrangement in Saudi Arabia, called misyar marriage, also involves the husband and wife living separately but getting together regularly.[24] Marriage is not a prerequisite for cohabitation. In the U.S., Jay Teachman, a researcher at Western Washington University, has studied premarital cohabitation.[25] Teachman’s study, "Shows that women who are committed to one relationship, who have both premarital sex and cohabit only with the man they eventually marry, have no higher incidence of divorce than women who abstain from premarital sex and cohabitation. For women in this category, premarital sex and cohabitation with their eventual husband are just two more steps in developing a committed, long-term relationship."[26]

Census Estimates

edit

The U.S. Census Bureau reports that the age at which people first marry is rising. "In 1970, the median age at first marriage was 20.8 years for women and 23.2 years for men. By 2003, these ages had risen to 25.3 years and 27.1 years, respectively."[27] In a working paper dated December 2006, a member of the U.S. Census Bureau staff estimated that, "Among the 224.9 million people 15 and older in the United States in 2004, 56 percent of men and 51 percent of women indicated they were currently married, 9 percent of men and 11 percent of women were divorced, and 2 percent of men and 3 percent of women were separated."[28]
