A routine cargo run with a not-so-routine footprint<\/h2>\n\n\n\n
After two weather scrubs earlier in the week, one of them called at T-28 seconds because of anvil-shaped clouds that can trigger lightning near the pad, SpaceX launched CRS-34 on a Friday evening from Space Launch Complex 40 at Cape Canaveral Space Force Station. <\/p>\n\n\n\n

It was also the 108th land landing across the onshore pads SpaceX has used since 2015.<\/p>\n\n\n\n
The mission also leaned hard on hardware reusability. SpaceX flew booster B1096 for a sixth time, and Cargo Dragon C209 also notched its sixth flight, a first for a Cargo Dragon in the Dragon-2 era. Dragon separated from the upper stage about nine and-a-half minutes after liftoff and began an orbital chase of nearly 37 hours before arrival.<\/p>\n\n\n\n
Why the ISS still matters for Earth<\/h2>\n\n\n\n
It\u2019s easy to forget that the space station is not just a backdrop for cool videos and spacewalk photos. NASA says the ISS<\/a> has supported more than 4,000 experiments in microgravity involving researchers from more than 110 countries over more than 25 years of continuous operations.<\/p>\n\n\n\nCRS-34\u2019s cargo list also shows how \u201cspace science\u201d can loop back to everyday life. NASA says Dragon delivered experiments on how well Earth-based simulators mimic microgravity, a wood-based bone scaffold idea aimed at fragile bone conditions like osteoporosis, and tools to study how red blood cells and the spleen change in space. <\/p>\n\n\n\n
NASA also highlighted instruments to monitor charged particles around Earth and to take highly accurate measurements of sunlight reflected by Earth and the Moon, a reminder that climate-relevant data sometimes starts in orbit.<\/p>\n\n\n\n
Rocket soot and the ozone question<\/h2>\n\n\n\n
The environmental concern is not just carbon dioxide. A peer-reviewed analysis led by NOAA researchers describes how rockets emit black carbon particles directly into the stratosphere, where they can accumulate, absorb sunlight, and warm surrounding air. <\/p>\n\n\n\n
In their model, a 10 gigagram-per-year black carbon scenario increased stratospheric temperatures by as much as 1.5 kelvin and reduced ozone in the Northern Hemisphere by as much as 16 Dobson Units<\/a> in some months.<\/p>\n\n\n\n\n\n\nAlso Read: SpaceX is starting to move on from Falcon 9, the world\u2019s most successful rocket, and Starship is already changing the launch map\u00a0<\/a><\/h4>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\nAnother recent study in npj Climate and Atmospheric Science makes the ozone risk more concrete as launch rates rise<\/a>. Its \u201cambitious\u201d scenario of 2,040 launches per year found a 0.29% depletion in near-global total column ozone in 2030, with Antarctic springtime ozone decreasing by 3.9%, and it notes global mean ozone remains about 2% below pre-CFC levels.<\/p>\n\n\n\nBusiness incentives and defense realities<\/h2>\n\n\n\n
CRS-34 is funded through NASA\u2019s Commercial Resupply Services contracts, which is a business model that treats access to orbit as a service to be purchased rather than a vehicle to be owned.<\/p>\n\n\n\n
