Hienoa, että avoimen kirjeemme (ks. alla) takia avaruusetiikka kiinnostaa!

Time to Act in #Space! 🚀 The “Cosmic Footprint Initiative” with Prof. Claudius Gros (#GoetheUni) calls for consideration of the ethical consequences of space travel. What does our #cosmicfootprint mean for future generations? 🧪 www.cosmicfootprint.org?section=Call....

Tutkijat vaativat toimia ihmiskunnan "kosmisen jalanjäljen" suhteen Tutkijoiden laatiman avoimen kirjeen mukaan ihmiskunta elää kriittistä hetkeä, minkä takia on ratkaisevan tärkeää tunnistaa ja kantaa vastuu kosmisesta jalanjäljestä.

Myös avaruudella on rajansa: tutkijat vaativat vastuunottoa "kosmisesta jalanjäljestä"

Kosmisen jalanjäljen käsitteellä asiantuntijat tarkoittavat ihmisten toiminnan jopa peruuttamattomia vaikutuksia avaruuteen. Kansainvälinen tutkijajoukko haluaa tuoda ongelman osaksi sekä akateemista että laajempaa keskustelua.

"[H]umans are ending 3.5–3.8 billion years of relative isolation of the terrestrial biosphere from interaction with its cosmic environment, and may now leave lasting physical, chemical, biological, and unforeseen impacts beyond Earth."

In it, we:
1. Introduce the concept of Humanity’s Cosmic Footprint.
2. Emphasise the need to address ethical questions surrounding our expanding cosmic influence.
3. Propose establishing a registry to represent and track humanity’s cosmic footprint, providing a ground for informed discussions.

Wow, a new interesting piece about value theory and space exploration, check it out! 🤩

Kudos to SpaceX for figuring out that it's more efficient to simply let Starship explode on the pad rather than having to actually launch it first

Long-term Future and Non-anthropocentric Value Abstract Longtermism, the view that emphasizes the importance of the long-term consequences of our actions, has predominantly been focused on humans. Gary O’Brien (2024) argues that this is a mistake ...

My new article, ”Long-term Future and Non-anthropocentric Value,” is now published! In it, I re-examine Gary O’Brien’s recent article on longtermism and animals, and I expand beyond animals to explore what considering broader environmental values could mean for the very long-term.

Why space exploration must not be left to a few powerful nations Indigenous people and others need a say in space-industry decisions. Here’s how that can happen.

Kysyn, mitä voin tehdä Gazan tilanteeseen liittyen. Asiantuntija vastaa 👇

Orbital data centres 👀

Alex de Waal | Starvation in Gaza Twice already during this war, the people of Gaza have pulled back from the brink of categorical famine – both times...

‘Adults are going hungrier to keep children better fed. The most vulnerable – infants, pregnant women, breastfeeding mothers and others needing special diets – are already starving.’

Alex de Waal on famine in Gaza, from the blog: www.lrb.co.uk/blog/2025/ma...

Failed Soviet Venus lander Kosmos 482 crashes to Earth after 53 years in orbit Kosmos 482 has come home.

The re-entry of Kosmos 482 "draws attention to our planet's growing space junk problem. On average, three sizeable pieces of debris crash back to Earth every day — and that number is only going to go up.”

The west’s shameful silence on Gaza The US and European allies should do more to restrain Benjamin Netanyahu

Nyt myös Financial Timesin editorial board tuomitsee lännen häpeällisen hiljaisuuden ”Gazan katastrofin” edessä.

Ne, ketkä ovat hiljaa, ovat osallisia.

Lol 😅 this ”lets move polluting industries to space” -mantra makes little sense! 🤦‍♂️

They'll help me communicate about my research projects, so send me your favourites by replying or by DM! 🙏

”the funding can be used to recruit researchers from outside Finland, for example from the United States, to Finnish universities.”

Congrats!! 💫👏

Perussuomalaiset vaativat nyt ilmastotavoitteesta luopumista. Se olisi kuitenkin yhä aivan mahdollista saavuttaa, sanoo tutkimusprofessori. Iltapäivisin julkaistavassa Pihvi-ohjelmassa valitsemme jokaisena arkipäivänä yhden olennaisen uutisen ja selvitämme, mistä se oikeastaan kertoo.

Ilmastolain mukainen hiilineutraaliustavoite on mahdollista saavuttaa, sanoo @raisamakipaa.bsky.social. Poliittisilla päättäjillä on useita ohjauskeinoja vielä käyttämättä.

Our world is full of nuances. Forgetting this and choosing black or white means diving into obscurantism. What we have seen unfold in the last few weeks regarding space exploration is sad, to say the least.

🚀👨‍🚀🔴 I have been advocating for the scientific exploration of Mars for years.

This is Marco Rubio explaining how the USA promised to defend Ukraine forever if they got rid of their nuclear arsenal left after the Soviet Union fell.

This is why lil marco was sinking into the couch. He was hoping we wouldn’t find it…so don’t RT right now this very second.

Posters of students killed in by Russia, defending Ukraine.

”The worldwide exhibition which uncovers the stories of Ukrainian students who will never graduate because their lives were taken by the Russian invasion.”

Unissued Diplomas exhibition at the University of Helsinki.

Remembering all Ukrainian students who never got to graduate. Heartbreaking.

Fuck Russia, Putin, and everyone who sides with imperialist slaughterers.

Slava Ukraini. 🇫🇮🤝🇺🇦
