If you’re less than 25 years old, you never experienced a situation in which all the people was present on the Earth at any time!
Since today 25 tears ago the Expedition 1 in the International Space Station began! What a feat for the whole humankind 🥰.

It’ll be available in most (Czech) bookstores in just a few days.
If you’re into the Arctic, Antarctic, or just science stories told through real people, this one’s for you. 🌍

Zdeněk also asked me to contribute as one of the interviewees — and to share some photos.
The book’s large format really makes the visuals stand out. 🙃

The book is dedicated to Josef Svoboda (1929–2022), a legendary Arctic ecologist who emigrated to Canada after years in a communist prison.
The Czech research station on Svalbard now carries his name. ❄️

He says all the scientists agree on one thing — humans are responsible for today’s global changes.
But their outlooks differ: older researchers tend to be more pessimistic, younger ones more hopeful.

New book out soon! 📖 (Unfortunately only in Czech)
Planet of Melting Ice by Zdeněk Zvonek brings together 19 interviews with scientists from all sorts of fields — from biology to geology to social science — all united by one thing: their work in the polar regions. 🧊

Not only the Prague planetarium have the most modern LED projection in the world. They also do have these awesome mirrors on toilets! How cool is that?! 😍

Cool pictures of Luca Parmitano during the training in Orion mockup with his NASA collegaues.
They were practicing recovery procedures for the Artemis II astronauts for next year.
It is nice to see the @esa.int patch on Orion space suit! I guess Luca is first in the line for ESA Artemis seat. 🚀

Hello Crew-11! 👋
I am so happy for Zena Cardman. After getting bumped from Crew-9 she is finally going! And again as a commander.
Polar scientists turned astronauts are the best!

The last one which is also pretty cool took Japanese Moon orbiter Kaguya in 2009. Not directly from the surface, but still very nice indeed! 🙃

And what connection they had to the Surveyor 3 space probe? Well, they landed just few hundred meters apart! Astronauts Pete Conrad and Al Bean even took the TV camera and some other parts of this space probe back to Earth. Pretty cool feat if you ask me...!

Another cool picture of sun eclipse took crew of Apollo 12 on its way to the lunar surface two years after. Which has some connection to Surveyor 3 as well! Astronauts had Hasseblad camera, so the quality is much better!

Did you know that a spaceprobe (Moon lander) took a similar photo almost 60 years ago? That was Surveyor 3. Only its TV camera wasn't as good...

Erebus volcano in Antarctica as seen by me from Ob Hill near McMurdo (oct 2018). That picture up there is quite something! Are those clouds all around the volcano?

Beautiful new pictures from @esa.int Hera spacecraft of Mars and its moon Deimos!
Hera is on its way to Dimorphos - a small moon of asteroid Didymos. The other spacecraft - DART - smashed to this moon few years ago to test, if we can (unlike dinosaurs) defend ourselves against the asteroid impact!

SPHEREx will thus complement the existing fleet of space telescopes very nicely and will hopefully help us to solve some of the burning mysteries of how we got here in the first place...

SPHEREx is a "survey" telescope - its observations are continuous and essentially determined by celestial mechanics, whereas JWST is a targeted telescope. And its observing time is hard fought for. And each science team has to request it through an elaborate plan.

It will survey the entire sky in the first six months and all the data will be publicly available. This will help scientists working with JWST, for example. Thanks to SPHEREx, they will be able to pick out interesting objects, which they will then be able to look at in much more detail with JWST.

The telescope will determine this by spectral analysis of the light emitted by such particles. Many compounds or elements, such as water, have a unique "fingerprint" in their spectra. And that's what SPHEREx will be able to measure.
