Back to back cargo deliveries mark busy week aboard ISS. Two different cargo ships arrived at the International Space Station this week, each returning their respective vehicles to flight status following accidents and setting new historic milestones. On Wednesday, February 22, a SpaceX Dragon spacecraft with 5,473 pounds of cargo arrived at the complex on the CRS-10 mission. Dragon launched February 19 on what was the first post-shuttle use of the historic LC-19A launch pad at Kennedy Space Center. CRS-10 was the first SpaceX launch from Florida since the Amos-6 accident in September 2016, destroyed their primary launch complex, SLC-40. Less than a day later, on February 23, Progress MS-05 arrived with 5,401 pounds of cargo following its launch from Baikonur Cosmodrome. MS-05, known as 66P in the ISS vehicle manifest, marked the final launch of the Soyuz-U rocket, a variant of the historic rocket that has made 786 flights since 1973. The modern Soyuz-2 rocket rendered the Soyuz-U variant obsolete in 2015. Progress MS-05 was the first Progress flight since the December 1 2016, launch failure of Progress MS-04.
