One year ago today, #MarsHelicopter Ingenuity was deployed from Mars rover Perseverance, where it was stowed during the journey to the Red Planet. Ingenuity touched down on the Martian surface, survived the frigid night, and went on to make history two weeks later.

My latest Escape Room article in @RSC_EiC is out today with a microscale chemistry theme, encouraging students to observe, think and explain. It is very much inspired by the work of Alex Johnstone and @UncleBo80053383

Thanks for being the bright spot in our days, @NASASun! Happy Valentine's Day!

Valentine's Day 🤝 Superb Owl It's not everyday that these two events converge so perfectly, but then these great horned owlets decided to pose in a heart-shaped tree hole. ❤️🏈 📷: Jon LeVasseur

They say pictures are worth a thousand words, but sometimes they leave you speechless. On this day in 1984, astronaut Bruce McCandless made the first untethered spacewalk using the Manned Maneuvering Unit (MMU).

At 2pm today @ndbrning, of @compoundchem fame, will be exploring science careers pathways at #ASEConf2022 📍 https://t.co/piTFpReNxY Get familiar with Andy's work 👇 https://t.co/vgcapYyc9u Then explore some career resources: 👨🏻‍🔬 https://t.co/45ms7j6kH6 #scied #ukedchat #chemchat

If you know your chemistry, you can figure out what's going on here #ChemEdX

On Earth, gravity makes it easy to do things like drink a glass of water or add fuel to a tank. But in space, fluids behave very differently. Check out the strange way fluids slosh on the @Space_Station & how it affects crew. https://t.co/GU9uArcvmS

"We must stay the course and continue our efforts to ensure that all of our children remain in schools." See a community letter from Dr. Brabrand on how we are maintaining our mask requirements within a caring culture:

Get vaccinated. Wear a mask. Save lives. As COVID-19 continues to impact communities around the world, help stop the spread by following these steps → https://t.co/KrKnHmD9f1 #GoogleDoodle

CONFIRMED: “The world’s most sophisticated tripod” has not only deployed but also latched! Each of the struts for this tripod, which helps #NASAWebb’s secondary mirror direct light into the instruments, is about 25 feet long (7.6 m)! https://t.co/QTAt5yn8zF #UnfoldTheUniverse

Don’t lose your chill — helium is the coolest element. (It's got the lowest boiling point!) Apply pressure, and it gets even cooler. Find out how pressurized helium helps keep the cryocooler of Webb’s MIRI instrument about 7 degrees Kelvin (-448 degrees F, or -266 degrees C)! ❄️

Deuterium, an isotope of hydrogen, can be used in climate science, NMR spectroscopy, medicinal chemistry, and nuclear reactors. ⚛️ Check out the #PeriodicGraphics by @compoundchem: https://t.co/9QmeU84fo8 See more chemistry infographics at https://t.co/d9jSQqdblf

"Everything is made from a chemical reaction." Laureate David MacMillan received the chemistry prize for his work on organocatalysis. In his #NobelPrize lecture today he explained exactly what catalysis is, and why it's important. Watch the full lecture: https://t.co/9hsV94A7q9
