[LINK] “Bill Nye’s Lightsail solar sailing spacecraft wins on Kickstarter”

The Kickstarter campaign described by the Planetary Society’s Richard Chute for a solar sail craft was a huge success. CBC reports.

A campaign to launch a small spacecraft propelled through space by ultra-thin solar sails has crowdfunded enough in just one day to build the spacecraft.

The private, non-profit Planetary Society and its CEO Bill Nye had raised $200,000 on Kickstarter by Wednesday afternoon, just a day after they launched their campaign to help fund their LightSail spacecraft.

The bread loaf-sized spacecraft is powered by solar sails, designed to capture the momentum from solar energy photons using large, mirrored surfaces. The small, continuous acceleration allows a spacecraft propelled by solar sails to reach high speeds over time without carrying or burning any fuel.

The money raised on Kickstarter will cover construction of the spacecraft used in the primary mission, which will launch in 2016. A low-altitude test flight is scheduled to launch May 20.

Altogether, the project is expected to cost $5.46 million. The Planetary Society says it has $1.2 million left to raise.

[BLOG] Some Thursday links (1)

I’ve accumulated more than a few links in the past couple of weeks. I wanted to share them, in two posts, before I left Toronto on a week-long vacation in Prince Edward Island.

  • Acts of Minor Treason’s Andrew Barton shares a vintage photo of Toronto’s Union Station from 2010, before the massive construction on Front Street that transformed the scene.
  • Bad Astronomy’s Phil Plait notes that the very large majority of stars in the night sky are quite likely to still be alive, not having died in the mere tens of thousands of years (at most) it has taken for their light to reach us.
  • The Burgh Diaspora’s Jim Russell notes that German attitudes which force women to choose between motherhood and employment aren’t going to work in the long run.
  • Centauri Dreams suggests that landing sites on icy Europa’s chaos regions are likely to give probes access to its biologically interesting water oceans, and notes the serious problems associated with focusing lasers for interstellar solar sails across light years of space.
  • Crooked Timber’s Chris Bertram notes the hardening of British attitudes towards migrants, while John Quiggin notes the role of nepotism in the centres of globalization.
  • The Dragon’s Tales has plenty of interesting links: one suggesting that known exoplanet systems seem to follow Kepler’s law, another suggesting that habitable exomoons are likely to orbit at least part of the time outside of the local stellar habitable zone if they’re to avoid overheating, and a third one mapping the genetic legacies of different ancient migrations to the Western Hemisphere.
  • Eastern Approaches notes the new cosmopolitanism and experimenting of Polish cuisine and chronicles the destructiveness of the continued alienation and even oppression of the Roma of Hungary.
  • Far Outlier’s Joel notes the growing popularity of baseball in the late 19th century Kingdom of Hawai’i and chronicles the origins of smallpox inoculation among the beauty practices of Circassian female slaves.
  • A Fistful of Euros’ Alex Harrowell makes an argument that independent satellite surveillance played a role in the decisions of France and Germany not to involve themselves in Iraq. Commenters dissent, suggesting that an Italy equally plugged into Franco-German networks didn’t care about the intelligence.
  • Joe. My. God. notes that a bare majority of Taiwanese now support same-sex marriage, and comments approvingly about American gay conservative Jamie Kirchick’s calling out of Russian homophobia on Russia Today at the expense of his career with that station.
