The Week in Launches: A New Set of Solar Arrays Arrived at ISS

A SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida with a Cargo Dragon spacecraft carrying more than 7,700 pounds of research, hardware, and supplies as part of the company’s 36th commercial resupply mission to the International Space Station on November 26, 2022.

SpaceX launched a resupply ship that delivered a new set of solar panels to the International Space Station (ISS) during a week that saw four launches from the United States, China and India.

SpaceX’s Cargo Dragon carried a pair of International Space Station Roll-Out Solar Arrays (iROSAs) in its unpressurized trunk. This is the second of three sets of iROSAs to be sent to the space station; the first was installed in 2021. The new solar panels will provide a 20-30 percent increase in power for space station operations and research.

Rollout solar panels were used on NASA’s Double Asteroid Redirection Test mission, which changed the orbit of the asteroid moon Dimorphos by intentionally crashing into it on Sept. 26. NASA will also use rollout solar panels to power the lunar Gateway, a human-tended station that will orbit the moon.

The Cargo Dragon also carried six CubeSats that astronauts will deploy from ISS.

NationSuccessesFailuresPartial FailuresTotalPercentage of Total
United States77218048.2
South Korea10010.6

China is in second place with 54 launches, including 53 successes and one failure. The state-owned China Aerospace and Science Corporation has conducted 46 of the nation’s launches. ExPace has successfully launched its Kuaizhou-1A rocket four times, Galactic Energy’s Ceres-1 booster flew twice, and CAS Space conducted a successful maiden flight of its ZK-1A rocket. The lone attempt by i-space to launch its Hyperbola-1 booster ended in failure.

Russia is a distant third with 21 launches. India completed its fifth and final launch of the year last week. Europe’s Arianespace has one launch each of the Ariane 5 and Vega-C rockets scheduled for December.

Iran, South Korea and Japan have launched one rocket apiece.
