The Download: Saving the “doomsday glacier,” and Europe’s hopes for its rockets

The Thwaites glacier is a fortress larger than Florida, a wall of ice that reaches nearly 4,000 feet above the bedrock of West Antarctica, guarding the low-lying ice sheet behind it.

But a strong, warm ocean current is weakening its foundations and accelerating its slide into the sea. Scientists fear the waters could topple the walls in the coming decades, kick-starting a runaway process that would crack up the West Antarctic Ice Sheet, marking the start of a global climate disaster. As a result, they are eager to understand just how likely such a collapse is, when it could happen, and if we have the power to stop it. 

Scientists at MIT and Dartmouth College founded Arête Glacier Initiative last year in the hope of providing clearer answers to these questions. The nonprofit research organization will officially unveil itself, launch its website, and post requests for research proposals today, timed to coincide with the UN’s inaugural World Day for Glaciers, MIT Technology Review can report exclusively.

Europe is finally getting serious about commercial rockets

Europe is on the cusp of a new dawn in commercial space technology. As global political tensions intensify and relationships with the US become increasingly strained, several European companies are now planning to conduct their own launches in an attempt to reduce the continent’s reliance on American rockets.

In the coming days, Isar Aerospace, a company based in Munich, will try to launch its Spectrum rocket from a site in the frozen reaches of Andøya island in Norway. A spaceport has been built there to support small commercial rockets, and Spectrum is the first to make an attempt.

Regardless of whether it succeeds or fails, the launch attempt heralds an important moment as Europe tries to kick-start its own private rocket industry. It and other launches scheduled for later this year could give Europe multiple ways to reach space without having to rely on US rockets. Read the full story.
