The Download: dethroning SpaceX, and air-conditioning’s energy demands

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Rivals are rising to challenge the dominance of SpaceX

SpaceX is a space launch juggernaut. In just two decades, the company has managed to edge out former aerospace heavyweights Boeing, Lockheed, and Northrop Grumman to gain near-monopoly status over rocket launches in the US. It is now also the go-to launch provider for commercial customers, having lofted numerous satellites and five private crewed spaceflights, with more to come.

Other space companies have been scrambling to compete for years, but developing a reliable rocket takes slow, steady work and big budgets. Now at least some of them are catching up. Read the full story.

We should talk more about air-conditioning

—Casey Crownhart

Things are starting to warm up here in the New York City area, and it’s got me thinking once again about something that people aren’t talking about enough: energy demand for air conditioners.

I get it: Data centers are the shiny new thing to worry about. And I’m not saying we shouldn’t be thinking about the strain that gigawatt-scale computing installations put on the grid. But a little bit of perspective is important here.

I just finished up a new story about a novel way to make heat exchangers, a crucial component in air conditioners and a whole host of other technologies that cool our buildings, food, and electronics. Let’s dig into why I’m writing about the guts of cooling technologies, and why this sector really needs innovation. Read the full story.

The big story

The lucky break behind the first CRISPR treatment

December 2023

The world’s first commercial gene-editing treatment is set to start changing the lives of people with sickle-cell disease. It’s called Casgevy, and it was approved in November 2022 in the UK.

The treatment, which will be sold in the US by Vertex Pharmaceuticals, employs CRISPR, which can be easily programmed by scientists to cut DNA at precise locations they choose.

But where do you aim CRISPR, and how did the researchers know what DNA to change? That’s the lesser-known story of the sickle-cell breakthrough. Read more about it.
