Abstract Recycling carbon dioxide (CO2) remains a challenge for long-duration crewed missions, as carbon is an essential element to produce vital resources. This article is a review of the state-of-the-art technologies for removing and recycling metabolically produced CO2 in microgravity environments, including stations, habitats, vehicles, and suits.

The most entertaining political show last week was the National Assembly's special committee on prosecutorial indictment cancellation investigating the “salmon liquor party bribery” incident.

Approval ratings for the president hit record highs in the NBS and Gallup polls released a day apart last week, at 69% and 65%, respectively.

Since the results from both sides are similar, they can be seen as reflecting the current public sentiment.
