White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. πŸ§΅πŸ‘‡

Mark Kelly Says This 'Exciting' Scientific Find Raises Questions Of Life Beyond Earth NASA said the discovery shows such "building blocks" of life are "widespread throughout the solar system."

Thank you @captmarkkelly.bsky.social for sharing your excitement about the recent results from NASA's OSIRIS-Rex asteroid sample return mission! We are rewriting the textbooks on asteroid science and our understanding of the possibility of life elsewhere.

Yes, that will help. But you won't have the state of the art analytical instruments on Mars. There is never going to be a synchrotron radiation facility on Mars. We are using one of those now to study the organic matter in samples returned from asteroid Bennu by OSIRIS-REx right now.

Detecting definitive evidence for life beyond Earth using in situ spaceflight instruments is going to big a huge challenge no matter where you go..the recent report of possible evidence of.ancient life on Mars by Perseverance is the latest example. Answering this question demands sample return!
