[NEWS] Five space links: Hawaii, BepiColombo, Mars, GW170817

  • A habitat high in the mountains of Hawaii that once housed simulated Mars missions is now going to be home to a Moon base simulation, following a controversial recent run-through. The Atlantic reports.
  • D-Brief examines the electric thrusters of the BepiColombo probe.
  • Universe Today offers viewing tips for giant asteroid 3 Juno, here.
  • The neutron star collision producing GW170817 seems to have produced not a black hole, but a single hyper-massive neutron star. Science Daily reports.
  • Universe Today explores the prospects of the Mars InSight probe, set to land on the 26th, here.

[NEWS] Five sci-tech links: Freenet, smartphones, exoplanet mountains, kilonova, geoengineering

  • Motherboard takes a look at the Cleveland Free-Net, an early bulletin board system that was one of the first vehicles for people to get online in the 1980s, here.
  • Wired hosts an article making the case that blaming smartphones for causing human problems fits in an ancient tradition of human skepticism of new technologies, here.
  • Universe Today’s Matt Williams notes that upcoming generations of telescopes may be able to map mountains on exoplanets. (Well, really bumpy planets orbiting small stars, but still.)
  • The kilonova GW170817/GRB in NGC 4993, nearest detected source of gravitational waves, is continuing to brighten mysteriously. Matt Williams at Universe Today reports.
  • Brian Kahn at Earther notes that, although one popular theorized geoengineering method involving injecting sulfur dioxide into the upper atmosphere would greatly slow down global cooling and be good for almost all ecosystems, if it stopped rapid calamitous change would be the result.

[NEWS] Seven links on the neutron star collision in NGC 4993 (#gw170817)

  • This Guardian article went into great detail about th
  • You can tell that Bad Astronomer Phil Plait really enjoyed writing about the neutron star collision in NGC 4993.

  • Starts With A Bang’s Ethan Siegel provides a nice overview of GW170817.
  • Sophia Chen’s Wired article takes an interesting look at the culture of gravitational wave astronomy, traditionally secretive for fear of criticism.
