Summer is over. Underground, water freezes and the terrain above begins to crack. The resulting periglacial features indicate hidden ice on the Earth, but could such patterns also point to an accessible source of water on Mars? 🛰️ My latest for #JAXA Cosmos 🤸♂️🧪: cosmos.isas.jaxa.jp/digging-in-m...
A visit to the British Shop 🇬🇧 in Shibuya! It’s not that I passionate miss any particular food, but somehow it feels good to see the familiar favourites in a place where everyone else’s life experiences make your normal indescribably different.

I put down the cat tunnel in the hope that #CasperCat might start to play rather than pace. However, that is currently a nope 🤦🏼♀️😅

Automatic transfers (for example, to pay rent) at my bank can only be for a fixed period. After that, you have to set up the transfer again… in-person or by a month-long mail process as it’s not possible to do it online or by phone 🤦🏼♀️

I have honestly been wondering this all week.
Why exactly have the political media just noticed that massive racist Nigel Farage is a massive racist?

#ESAEnvision will address several key questions about Venus:
🌋 How geologically active is the planet today?
☁️ How are its thick clouds sustained?
🥵 How does Venus lose its heat?
💦 Where did its water go?
🪨 How does the planet’s surface change over time?

I have just sent a request to Purra the Kanganaut at the Australian Space Agency for a message to be included in a new campaign by the JAXA Martian Moons eXploration (MMX) mission.
I did include Purra's name in the list cleared with the mission team, but truthfully they may have missed this 😅

You’ve probably heard this claim: Climate’s always changing!
It's true, Earth’s climate has changed before. But not this fast, and not for this reason.

I was eating a sandwich on a bench when a random older dude came up and tried to talk to me. When I ignored him, he stood right in front of me, thrust his face at mine and said "konnichiwa".
He got a death glare. When that failed, I left.
It was NOT COOL. And yet... somehow I feel guilty.
