Meta & Fysikken: Afsnit 69: Liv i rummet og andre opdateringer

Vi lægger fra land med en tur i rummet.

Og Michael Linden-Vørnle's facebook opslag er også gode dertil.


2. Asteroide Sample fra Ryugu:

2020 fik vi samples fra Ryugu. Det viser sig at der er mere end 20 amino syrer!

3: Capstone sendt op af NASA

Weighing about as much as a suitcase, the satellite is trial-running an orbit for NASA's "Gateway" space station – which will travel around the Moon and serve as a jumping off point for lunar exploration.

Scientists hope the orbit will be super-efficient, using the pull of both the Moon and the Earth to minimize fuel use.

The orbit passes within 1.600 kilometers of the Moon at its closest point, before catapulting to 70,000 kilometers away at the furthest.


4: European startup builds oxygen-making machine for 2025 moon mission

In fact, if the oxygen stored in just the top ten meters of that regolith were made into a usable gas form, it is likely enough to support Earth’s entire 8 billion person population for as much as 100,000 years.

5: Artemis 1

We will build an Artemis Base Camp on the surface and the Gateway in lunar orbit. These elements will allow our robots and astronauts to explore more and conduct more science than ever before.
