Down to Earth

Retired NASA astronaut Terry Virts has published a “coffee table book” of images he took while aboard the ISS during Expeditions 42 and 43.

The 2017 Nobel Prize in Physics was awarded for the discovery of gravitational waves by the LIGO team.

Canadian company MDA has acquired DigitalGlobe and the new merged corporation will be changing their name to Maxar Technologies. MDA is the company that build the Canadarms and DigitalGlobe is a major provider of orbital imagery for users like Google.

In Orbit

Three rocket launches since my last post. All of them occurred today, October 9th:

  • China launched a Long March 2D rocket carrying a Venezuelan satellite.
  • SpaceX launched a Falcon 9 rocket carrying 10 new communication satellites for Iridium.
  • Japan launched an H-2A rocket carrying a native navigation satellite.

Things have been quite busy up on the ISS. Astronauts Mark Vande Hei and Randy Bresnik executed the first of a series of spacewalks last week to maintain the station’s robotic arm. They will go out again tomorrow, October 10th, to continue the work. Here are a few pictures from last week’s EVA:

NASA has announced plans to keep the Bigelow Expandable Activity Module (BEAM) on the ISS for longer than planned and use it as a logistics module.

Out There

A recent study of “Tabby’s Star” using NASA’s orbiting observatories Spitzer and Swift hasĀ a new theory for the unexplained dips in brightness: dust. The new hypothesis is compelling because the telescopes detected differences in the dimming at different wavelengths, which implies something transparent like dust.
