Russian Progress MS-03 departs ISS

With the undocking of a Russian Progress cargo ship from the International Space Station, only two spacecraft remain at the outpost – a rarity in an era of high visiting vehicle traffic.

Progress MS-03 undocked at 9:25 a.m. EST (14:25 GMT) Jan. 31, 2017, from the Pirs docking compartment on the Earth-facing side of the ISS after spending six months there.

Japan's Kounotori 6 leaves ISS, readies tether experiment

Japan's Kounotori 6 leaves ISS, readies tether experiment

After six weeks attached to the International Space Station, Japan’s Kounotori 6 spacecraft was unberthed and commanded to leave the vicinity of the outpost. It will now spend a week conducting a few stand-alone experiments for the Japan Aerospace Exploration Agency.

A few hours after ground teams commanded the 17.5-meter long robotic Canadarm2 to move the spacecraft, also called the H-II Transfer Vehicle 6, from the Earth-facing port of the Harmony module to about 10 meters below the Destiny laboratory to release it.

NASA mulls purchasing Soyuz seats—from Boeing?

NASA mulls purchasing Soyuz seats—from Boeing?

Despite the Commercial Crew Program being years behind schedule, NASA has said for the last number of months that it has no plans to purchase additional Soyuz seats from Russia past the end of 2018. While that may technically hold true, the U.S. space agency is, however, looking to buy Soyuz seats acquired by Boeing.

Astronauts breeze through spacewalk, complete all get-ahead tasks

Astronauts breeze through spacewalk, complete all get-ahead tasks

In the second of two planned to spacewalks up upgrade the International Space Station’s power system, two astronauts finished the process of replacing 12 nickel-hydrogen batteries with new lithium-ion units. The spacewalking duo worked so fast, they had time to complete all of the assigned get-ahead tasks.

Astronauts to finish installing batteries during Jan. 13 spacewalk

The International Space Station crew is gearing up for the second of two spacewalks aimed at replacing aging nickel-hydrogen batteries with new lithium-ion units. Two astronauts will leave the Quest airlock at around 7 a.m. EST (12:00 GMT) Jan. 13, 2017, for an estimated six-and-a-half-hour-long excursion.

1st battery-replacement spacewalk completed at ISS

1st battery-replacement spacewalk completed at ISS

Two NASA astronauts on the first of two spacewalks outside the International Space Station made swift work to help with the replacement of old batteries with new lithium-ion units. They even had enough time left over to perform several get-ahead tasks.

Extravehicular Activity 38 began at 7:23 a.m. EST (12:23 GMT) Jan. 6, 2017. It was performed by NASA astronauts Shane Kimbrough and Peggy Whitson. The goal was to install three adapter plates next to three lithium-ion batteries that were installed robotically late last week.

Robotics work clears way for Friday spacewalk

Robotics work clears way for Friday spacewalk

On Friday, NASA astronauts Shane Kimbrough and Peggy Whitson will venture outside the 400-metric-ton International Space Station on the first of two spacewalks to begin a multi-year process of upgrading the outpost’s power system.

The spacewalk, Extravehicular Activity 38, will see the two Expedition 50 astronauts install battery adapter plates and help with the swap-out of old nickel-hydrogen batteries with new lighter and more efficient lithium ion units.

Video: Jeff's Earth in 4K

In a stunning five-minute ultra high-definition video released by NASA at the end of 2016, retired NASA astronaut Jeff Williams recounts his time spent orbiting Earth aboard the International Space Station.

Williams, who returned to Earth Sept. 7, 2016, on his fourth and final trip into the black, has spent more than 534 days in space over his career—more than any American astronaut as of this writing.

Cargo ships, expandables and spacewalks: ISS in 2016

Cargo ships, expandables and spacewalks: ISS in 2016

Between cargo ships servicing the outpost and spacewalks to maintain it, 2016 was arguably one of the busiest years for the International Space Station since the end of the space shuttle era.

Probably the most visible event for the space station in 2016 was the yearlong crew – NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko – returning to Earth. They had launched to the outpost on March 27, 2015.

Orbital Velocity in 2017

Orbital Velocity in 2017

Since August, I have been working to give Orbital Velocity a basic functionality. Currently, about two blog posts are produced a week and content has been created for the spacecraft that currently service the International Space Station.

With 2016 coming to a close, it’s time to create a road map for 2017. This road map will change as more funds and time are contributed to it. But before going over that, it might be important to describe what was and wasn’t accomplished in the last five months.
