I'm talking to a journalist in a bit about NASA's new "space sustainability strategy" and this one sentence from the abstract seems to sum it up:

"Given the substantial upfront expenditures required to develop and deploy remediation capabilities and the potential delay in receiving benefits, these motivations do not appear to be sufficient to incentivize immediate action"

I'm going to have to read this more carefully, but did NASA just say they don't care about orbit?!

Strange science facts: In nuclear power, functional nuclear fission reactors were constructed as early as 1942, yet nuclear fusion remains elusive and can only be achieved for short periods. In jazz, on the other hand, jazz fusion was invented in the early 70s, and jazz fission remains purely theoretical even today

Ya está disponible mi entrevista en Xataka, donde hablamos de la situación y el plan de rescate de Voyager 1 📡✨

This was avoidable.

I wonder who will be giving the mass at Peter Higgs' funeral?

In response to the energy crisis, Copenhagen dimmed the lighting in the city. A mobile ethnographic study among 22 female citizens asked them about their experience of the change. A total of zero had noticed that the lighting had changed. https://iopscience.iop.org/article/10.1088/1755-1315/1320/1/012015/pdf

No one knows how bright anything is. There is tremendous flexibility to reduce #LightPollution and #Energy waste, simply by dimming streetlights. If you're concerned about a #ClimateCrisis, dimming is one of the easiest steps to take.

Last night, triggered by recent cosmology news & my own current research experience, I wrote a blog post on my ambivalent feelings as an astrophysicist working in a beautiful field of perhaps unparalleled absolute significance, yet of almost negligible short-term relevance to the existential issues we humans and more broadly life on Earth are facing.
I hope it makes you think ! #astrophysics #ecology #climatecrisis

Pues que alegría saber que la Voyager 1 sigue viva y funcionando

Otra de flipar hoy. Pero ¿no se decía que no había que dar voz a delincuentes, abusadores y demás gentuza? De verdad que no entiendo que hace está señora entrevistando a este tipo. Bueno, si. Y no me gusta.

@pes_maravilla Ni horario de verano ni de invierno. ¡Igualdad!

Status update on the Voyager 1 spacecraft which has been sending a 0101 pattern since Nov 2023.

The problem seems to be a failed memory part in the FDS computer; engineers are planning to move ~200 words of software from one region to another, according to Joseph Westlake, director of NASA’s heliophysics division, who was speaking at a March 20 meeting of the National Academies’ Committee on Solar and Space Physics.

Westlake sounded very optimistic.

La rotación de la Tierra también está afectada por la crisis climática. Lo cuenta @aberron en @eldiarioes con comentarios de @Joaquin_Sevilla.
