Carbon-measuring instrument to be sent to ISS

Carbon-measuring instrument to be sent to ISS

When SpaceX’s CRS-17 Dragon spacecraft launches toward the International Space Station at the end of April, it is expected to be carrying with it a new carbon-observing instrument.

Called Orbiting Carbon Observatory-3, or OCO-3, the instrument is a follow-on to the still-active OCO-2 mission, according to NASA. Once at the ISS, it will be attached to the exposed platform on the Japanese Kibo module.

Astronauts install new batteries outside the ISS

Two NASA astronauts ventured outside the 20-year-old International Space Station to replace aging nickel-hydrogen batteries with fresh lithium-ion units.

Floating outside the Quest airlock to perform the 6.5-hour-long U.S. EVA-52 was NASA’s Anne McClain and Nick Hague, both Expedition 59 flight engineers.

Soyuz MS-12 reaches ISS, Expedition 59 begins

After a successful launch from Baikonur Cosmodrome in Kazakhstan, the Soyuz MS-12 spacecraft rendezvoused and docked with the International Space Station some six hours later.

Aboard Soyuz MS-12 was Russian cosmonaut Aleksey Ovchinin and NASA astronauts Nick Hague and Christina Koch. The spacecraft’s arrival at the Earth-facing port of the Rassvet module at 01:01 UTC March 15 doubled the outpost’s crew size and set the stage for a busy next couple of weeks of spacewalks and science.

Historic Crew Dragon flight concludes with Atlantic splashdown

The historic Crew Dragon Demo-1 mission has come to a conclusion with a successful splashdown in the Atlantic Ocean not far from where its mission began six days ago.

Following a five-day mission attached to the International Space Station, the unpiloted Crew Dragon autonomously undocked at 07:32 UTC March 8, 2019, and began moving to a safe distance. The spacecraft left the vicinity of the outpost about 20 minutes later.

ISS astronauts assemble tools for robotic refueling demo

If humans are ever to settle the Solar System sustainably, a number of technologies will need to be perfected, including in-space refueling.

As such, NASA created the Robotic Refueling Mission, or RRM, a series of experiments designed to understand and perfect technologies for robotic propellant transfer and help extend the life of spacecraft.

NG-10 Cygnus ends post-ISS mission after deploying satellites

NG-10 Cygnus ends post-ISS mission after deploying satellites

Having launched Nov. 17, 2018, and spent 81 days attached to the International Space Station, the NG-10 Cygnus, named SS John Glenn by Northrop Grumman, was unberthed Feb. 8 to perform a two-week stand-alone mission. That post-ISS flight came to an end at about 09:00 UTC Feb. 25, 2019, when the spacecraft’s engine performed a deorbit burn to lower its orbit enough for Earth’s atmosphere to drag it down, safely burning it up of the Pacific Ocean.

NASA planning to buy 2 more seats aboard Russian Soyuz spacecraft

NASA planning to buy 2 more seats aboard Russian Soyuz spacecraft

While the first Commercial Crew flights are just around the corner, NASA is looking to buy a little more buffer time in order to ensure uninterrupted access to the International Space Station.

First reported by NASASpaceflight, a procurement document published on Feb. 13, 2019, shows the U.S. space agency is looking to buy two more seats aboard Russian Soyuz spacecraft. These seats would presumably be on Soyuz MS-15 and Soyuz MS-16 in the fall of 2019 and spring of 2020 respectively.
