Absolutely incredible.

NASA Astronaut Reid Wiseman, who commanded Artemis II, took this footage from the far side of the Moon with his iPhone.

Watch with sound on.

These are the NASA projects that the Trump regime are terminating. Some provide vital data to monitor the weather and climate of the planet. Many are already fully operational and are to be discarded.

Now would be a great time to reconsider that 46% cut to NASA’s science budget for FY2027.

Trump's 2027 budget proposes cuts of:

🔻 $5.8 billion to NIH

🔻 $5.6 billion to NASA

🔻 $4.8 billion to NSF

🔻 $4.6 billion to EPA

🔻 $2.9 billion to CDC

🔻 $1.6 billion to NOAA

If these science cuts pass they will make the US a less healthy and less safe place to live.

For added perspective, Trump’s devastating cuts to US science equate to something like just 3 weeks of military spending due to war he started. (Seems like $1B a day or so is what’s been estimated for the war). So sure. Gut US science for a couple extra weeks of war…

The Supreme Court did not strike down conversion therapy bans today.

Not nationwide. Not in Colorado. Not anywhere.

Here's what actually happened in Chiles v. Salazar—and why the coverage you're seeing serves the conservative legal movement more than it serves you.

The Supreme Court just struck down Colorado's conversion therapy ban. They have now legalized the systematic torture of LGBTQ youth and invalidated the laws that protect them from this abuse.

Transgender women banned from Olympics by new IOC policy The new policy limits eligibility in women’s events to biological females based on genetic screening beginning at the 2028 Games.

The IOC has announced a trans and intersex athlete ban requiring an invasive SRY genetic test for female athletes.

In the 20+ years trans women were eligible, only one ever competed and none ever medaled. This is solving for a problem that doesn't exist.
