Ceres





Watch NASA’s Dawn Spacecraft Buzz Dwarf Planet Ceres in the Asteroid Belt
Ceres accounts for 25% of the mass of the asteroid belt, and unlike most of its irregularly shaped neighbors, it is massive enough to be nearly spherical like a moon or planet. ..... Models of the dwarf planet’s interior suggest its mantle may consist of a slurry of water and dirt that contains more fresh water than Earth. .... early images from the Dawn mission showed mysterious bright spots on the surface .... highly reflective patches of surface ice are one possibility. ...... Discovering water on Ceres would have implications for space exploration. Water is a potential source of hydration, breathable air, and rocket fuel, and will therefore prove a precious resource for space wanderers. .... Ceres would make a good extraterrestrial outpost. Its low gravity makes landing and taking off less energy intensive, and resources on the surface could resupply missions—perhaps even trips to the outer solar system.

Relationships

A Mosuo woman near Lugu Lake.Image via WikipediaRecently I read this article. I think it could inspire conversations.

The Atlantic: All The Single Ladies

Some observations I made:

(1) Having a job and paying her own bills is still such a big deal for this woman. This is 2011. You'd think having a job by now would be something to take for granted for women.

(2) There is no one right lifestyle. True. But a lot of people end up with default lifestyles rather than the one they would actively pick for themselves. If you are to stay single, make sure it is an active, conscious choice.

My favorite part of the article was this one:
In her new book, Unhitched, Judith Stacey, a sociologist at NYU, surveys a variety of unconventional arrangements, from gay parenthood to polygamy to—in a mesmerizing case study—the Mosuo people of southwest China, who eschew marriage and visit their lovers only under cover of night. “The sooner and better our society comes to terms with the inescapable variety of intimacy and kinship in the modern world, the fewer unhappy families it will generate,” she writes.

The matrilineal Mosuo are worth pausing on, as a reminder of how complex family systems can be, and how rigid ours are—and also as an example of women’s innate libidinousness, which is routinely squelched by patriarchal systems, as Christopher Ryan and Cacilda Jethá point out in their own analysis of the Mosuo in their 2010 book, Sex at Dawn. For centuries, the Mosuo have lived in households that revolve around the women: the mothers preside over their children and grandchildren, and brothers take paternal responsibility for their sisters’ offspring.

Sexual relations are kept separate from family. At night, a Mosuo woman invites her lover to visit her babahuago (flower room); the assignation is called sese (walking). If she’d prefer he not sleep over, he’ll retire to an outer building (never home to his sisters). She can take another lover that night, or a different one the next, or sleep every single night with the same man for the rest of her life—there are no expectations or rules. As Cai Hua, a Chinese anthropologist, explains, these relationships, which are known as açia, are founded on each individual’s autonomy, and last only as long as each person is in the other’s company. Every goodbye is taken to be the end of the açia relationship, even if it resumes the following night. “There is no concept of açia that applies to the future,” Hua says.
This is exotic, don't you think?
