LEGO is releasing a “women of NASA” set.

The Apollo 11 capsule Columbia has started its around the country tour with a new exhibit at Space Center Houston: Destination Moon.

This Lyft commercial referencing the Apollo program is cute, but is missing a shout out to Michael Collins.

Jeff Bezos’ company, Blue Origin, conducted the first test fire of their new BE-4 rocket engine.

In Orbit

The ISS Expedition 53 crew completed the second and third spacewalks in their October series. All planned tasks were completed successfully, leaving the space station with some new cameras and a repaired robotic arm. The rest of the year on ISS will be focused on science research, with some critical deliveries onboard a Cygnus resupply and SpaceX Dragon resupply.

Since my last post on October 9th, there have been four orbital rocket launches:

  • October 11 – SpaceX launched a Falcon 9 rocket carrying two geostationary communication satellites. The first stage was a previously flown booster and was recovered on a droneship.
  • October 13 – A Russian Rokot launched carrying an Earth obesrvation payload for ESA.
  • October 14 – A Soyuz rocket launched from Baikonaur carrying an unmanned Progress resupply bound for the ISS.
  • October 15 – ULA launched an Atlas V rocket carrying a national security payload for the NRO.

The Progress freighter docked successfully two days after launch.

Below are a few of the best pictures taken onboard the ISS from the past two weeks. If you want to help maintain the amazing archive of millions of pictures of Earth taken from ISS, now there’s a way! Check out Cosmo Quest’s new Image Detective project.

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.

A recent study of “Tabby’s Star” using NASA’s orbiting observatories Spitzer and Swift has 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.

I’m back from my own personal August recess and catching up on almost a month of space news. Here’s your headline dump for August 14 to September 9! A lot has happened

Down to Earth

The Trump Administration has named Oklahoma Congressman Jim Bridenstine as their nominee for NASA administrator.

The Chinese and European astronauts conducted a joint survival training exercise off the coast of China.

Sierra Nevada Corporation conducted a “captive carry” flight of their Dream Chaser spaceplane.

Last week an ESA Ariane 5 rocket had a pad abort. The agency is still investigating.

In Orbit

The Dragon capsule launched two days earlier docked with the ISS on August 16th.

The day after the cargo. arrival, cosmonauts Fyodor Yurchikhin and Sergey Ryazanskiy conducted a successful spacewalk to do space station maintenance as well as some small satellites deployments.

Then on September 3rd a Soyuz returned to Earth, safely carrying Jack Fischer, Peggy Whitson, and Fyodor Yurchikhin to the steppes of Kazakhstan. Both Yurchikhin and Whitson now have accumulated over 600 days in space.

Meanwhile on the ground, a dedicated team of flight controllers was riding out Hurricane Harvey in Houston’s Mission Control Center to ensure the successful undocking and return of the crew.

Speaking of hurricanes, the ISS crew has taken some incredible imagery of Irma has it makes its way across the Caribbean and now Florida.

Lots of launches while I was out. Here’s a worldwide rundown:

Rocket Lab released some information about their failed test launch last month. It turns out the issue was due to some ground segment hardware and they should be able to recover and continue with another test launch soon.

SpaceX is removing the Rotating Service Structure (RSS) at pad 39A at KSC. The RSS was needed for Space Shuttle launches from the historic pad. The RSS from 39B has already been removed in preparations for the SLS program.

The much anticipated launch of the James Webb Space Telescope (JWST) may get delayed from late 2018 into 2019 due to a launch site conflict down in French Guiana, where JWST will be launched on an ESA rocket.

A Japanese rocket launch was cancelled this week due to an unspecified glitch. JAXA was trying to launch a new GPS satellite.

In Orbit

This morning, SpaceX launched a Falcon 9 rocket carrying a Dragon resupply capsule to the ISS. The launch was flawless with a successful first stage landing at Landing Zone 1. The Dragon will rendezvous with the ISS on Wednesday.

Among the cargo on the Dragon capsule is a new experimental super computer, a cosmic ray detector, and a slew of other experiments.

The 6-person Expedition 52 crew is really hitting their stride with their on-orbit photography, with daily Twitter updates to enjoy. The mission will wind down with the return of Peggy Whitson and Jack Fischer in early September, followed shortly by the launch of the second half of the Expedition 53 crew.

Google Lunar X Prize competitor, Moon Express, has received approval from the United States government for their private mission to land a rover on the moon.

Vector Space Systems completed their first successful sub-orbital launch.

In Orbit

Speaking of launches, there were four successful orbital flights since my last post. This brings the year’s total to 50 for 50 on orbital launches. For comparison, 2015 had 87 total with 5 failures.

First was an Atlas V launch from Cape Canaveral carrying a secret payload for the National Reconnaissance Office.

Second and third were two chinese launches carrying a new communications satellite and a radar imaging satellite.

Lastly was the SpaceX Falcon 9 launch early in the morning ofAugust 14. The rocket successfully delivered the Japanese JCSAT communications satellite to orbit and recovered the first stage booster on the ASDS at sea. Very impressive. This brings SpaceX’s year up to 8 successful launches for 8 attempts – a yearly record already in August – and 5 for 8 on booster recovery.

Coming up next week is a spacewalk on ISS by NASA astronauts Jeff Williams and Kate Rubins to install the new International Docking Adapter.
