The International Space Station may one day be forced to return to Earth, so that it safely burns up over the ocean, and this is actually a surprisingly complicated task given the huge mass of the station and the limited propulsion available. The plans aren't final by any means, but this discusses the problems and one particular option using multiple progress spacecraft to augment the propulsion and propellent available for deorbiting this historic orbital facility.

Korea (AKA South Korea) made the first launch of its KSLV-2 rocket this week, this is the first domestically developed orbital class rocket by that nation. The first 2 stages operated correctly, but the third stage shut down early leading to the payload burning up over the Indian Ocean. Regardless, this is a big step forward for this country's space Program. Previously Korea developed rockets using Russian technology based on the Angara and RD-151, or launched satellites using other launch providers, but as the nation has grown it has become able to sustain a home grown launch capability.

It's been a while since I talked about SpaceX's work on Starship, but in the last month I've been most excited by the reveal of the prototype for the Vacuum optimized version of the Raptor engine which is intended for the Starship upper stage.
