A kind reminder to all @esa.int's #LPS25 attendees that today during the 𝐂.𝟎𝟓.𝟎𝟒 session at 𝟏𝟔:𝟏𝟓-𝟏𝟕:𝟒𝟓 (𝐇𝐚𝐥𝐥 𝐋𝟏/𝐋𝟐) I will present on the global availability of usable Landsat and Sentinel-2 data and how it impacts feasibility of analyses.
Hope to see many of you in the audience!

Congress is making more than 250 million acres of public lands available for sale.
The Senate reconciliation package is a disturbing giveaway that will mandate the “disposal” of public lands across the western United States.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.

A daunting document outlining, among others, the future of the #Landsat program. Only a bunch of troglodytes could call the Landsat Next 'unaffordable', especially when its budget is like a drop comparing to the US military expenses.

Three Yale professors who have written extensively on authoritarianism are leaving the U.S. “We’re like people on the Titanic saying our ship can’t sink,” Marci Shore said. “And what you know as a historian is that there is no such thing as a ship that can’t sink.”

The decision by these three Yale professors to move to Canada is both a warning and a call to action.
