-Trump’s unconventional NASA pick signals Mars intentions in confirmation hearing [[https://kra30att.cc/|Кракен даркнет]]
+UK project trials carbon capture at sea to help tackle climate change [[https://kra34c.cc/|kra34.cc]]
-President Donald Trump’s pick to run NASA, Jared Isaacman, made waves Wednesday by signaling his intention to create a new focus on Mars exploration.
+The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.
-A confirmation hearing for Isaacman — the billionaire CEO of payments platform company Shift4 who has twice paid to fly aboard SpaceX capsules — kicked off before the Senate Committee on Commerce, Science and Transportation at 10 a.m. ET. The committee is not expected to vote on Isaacman’s confirmation until after lawmakers reconvene from a two-week break that ends April 28.
+The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.
-During the hearing, Isaacman faced wide-ranging questions about how NASA’s priorities might change under his leadership.
+Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.
-For months, the space agency and its commercial and international partners have faced uncertainty about how the Trump administration may seek to realign NASA’s missions to focus on Mars, rather than the moon.
+In the UK, where the government in 2023 announced up to £20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.
-If such a shift plays out, it could lead to changes for NASA’s Artemis program, which was announced during Trump’s first term and marked a renewed focus on lunar exploration. The Artemis I mission, for example, sent a crew-worthy spacecraft on a test flight around the moon in 2022. Artemis ultimately aims to return astronauts to the lunar surface and eventually create a permanent human settlement on the moon.
+“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.
-Notably, however, Mars has long been the destination of choice touted by Elon Musk, the founder and CEO of SpaceX who over the past year has become a close confidant of Trump and invested at least $260 million in his presidential campaign.
+“But it also means it’s very straightforward to take that carbon out of the water.”
-Currently, NASA does not have any concrete plans to send humans to the red planet, though the agency has routinely said it views lunar exploration as an important precursor to Mars missions.
+Pilot plant
-However, Isaacman told the committee he will “prioritize sending American astronauts to Mars.”
+SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.
-“Along the way, we will inevitably have the capabilities to return to the Moon and determine the scientific, economic, and national security benefits of maintaining a presence on the lunar surface,” according to Isaacman’s prepared opening statement.
+“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.
+The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.
