The amazing Shana Priwer and I are excited to announce the publication of our latest book! Physics 1 for Dummies (4th edition) is now available in bookstores & online. This is a great supplement to your student's high school physics class, or a fun refresher on motion & forces & pressure.

Gorgeous view of the NASA SpaceX Crew-11 reentry from my driveway in Southern California tonight!

Resharing a fun, recent conversation!

In a recent #SETILive discussion, @planetarypan.bsky.social and @planetcynthia.bsky.social discussed how an instrument built for a very different target was rapidly repurposed to study one of the rarest objects ever detected in the solar system. 🧪 🔭 👩‍🔬 Learn more: www.seti.org/news/3iatlas...

NASA’s fleet of Mars spacecraft will attempt observations of 3I/ATLAS as it passes by Mars on October 3! Stay tuned for results.

The government is shut down, but they can't stop me from posting stuff here. At Mars this weekend, it's all eyes on the skies. NASA's robotic explorers – in orbit and on the ground – will attempt observations when Comet 3I/ATLAS cruises past the Red Planet on Oct 3 www.youtube.com/watch?v=ZtQH...

Europa Clipper observes…. Mars? Yes, on its cruise to the Jupiter system, Europa Clipper swung by Mars for a gravity assist and captured this cool image of Mars and its two tiny moons.

Riding With Robots@ridingrobots.bsky.social · last yr.

On its way to Jupiter, NASA’s Europa Clipper caught a glimpse of Mars and its two moons. The dark (colder) circle at the top of the planet is a polar ice cap, and the fainter circle below is the region around Elysium Mons. Details: go.nasa.gov/3Uhjylf

Four charts showing the extent of cuts to NASA in the FY26 budget: - Cuts to every science division - Smallest science funding since 1984 - 19 active, inflight missions cancelled - Smallest NASA budget since FY 1961

BREAKING: The president's budget request just hit Congress, which could usher in a dark age for NASA space science. Congress has the final say, but you can help shape the outcome by adding your name to our global petition. This is just the start of our fight. Sign the petition: planet.ly/petition

Next stop for Europa Clipper: Mars??? That’s right, we are doing a rare Mars gravity assist on March 1st to help pick up speed on our journey out to the Jupiter system. More info and cool animations below!

Riding With Robots@ridingrobots.bsky.social · last yr.

From NASA: On March 1st, Europa Clipper will perform a gravity assist flyby of Mars, using the planet's gravity to adjust its trajectory as it makes its way to Jupiter. No visible light images, sadly. Details: go.nasa.gov/4bfYfba Ride along virtually: eyes.nasa.gov/apps/solar-s...

I gave a talk last week at the @agu.org conference on a fun project I've been working on with some colleagues, including amazing grad student Leah Sacks. We found a dark albedo feature on Saturn's moon Enceladus that we can show is changing over time! Check it out: www.space.com/space-explor...

Awesome news from Europa Clipper, which launched on October 14th. It's already traveled 13 million miles (!), and has successfully deployed its magnetometer boom and radar antennas. Next stop is a Mars flyby on March 1st! www.jpl.nasa.gov/news/nasas-e...
