In futurism and science fiction, the metaverse is a hypothetical iteration of the Internet as a single, universal and immersive virtual world that is facilitated by the use of virtual reality (VR) and augmented reality (AR) headsets. In colloquial use, a metaverse is a network of 3D virtual worlds focused on social connection.The term "metaverse" originated in the 1992 science fiction novel Snow Crash as a portmanteau of "meta" and "universe." Metaverse development is often linked to advancing virtual reality technology due to increasing demands for immersion. Recent interest in metaverse development is influenced by Web3, a concept for a decentralized iteration of the internet. Web3 and The Metaverse have been used as buzzwords to exaggerate development progress of various related technologies and projects for public relations purposes. Information privacy, user addiction, and user safety are concerns within the metaverse, stemming from challenges facing the social media and video game industries as a whole.

Vande Hei and two Roscosmos cosmonauts, Anton Shkaplerov and Pyotr Dubrov, are scheduled to end their mission aboard the International Space Station and return to Earth on Wednesday, March 30.

Vande Hei broke the record for longest single spaceflight by an American astronaut, previously held at 340 days. He will wrap up his second spaceflight with a total of 523 days in space.

Shelfis är en del av glaciäris som pressats ut i havet över kontinentalsockeln (shelfen) och därför flyter ovanpå havsvattnet. Man räknar en isplatta som shelfis när den höjer sig minst två meter över havsytan, men vanligtvis är den mellan 100 och 1000 meter tjock. Shelfisen är platt och fri från spänningar. Då is bryts av från shelfisen (kalvning), kan mycket stora isberg, s.k. taffelisberg, bildas.
Till skillnad från havsis, vilken bildas på havsvattnet bildas shelfis på ankar-is som ligger på kontinentalsockeln.
De största shelfisytorna ligger i Antarktis men shelfis förekommer också vid norra Grönland.

Ross shelfis, som täcker nära hälften av Rosshavet med en yta av ca 490 000 km².
Filchner Ronne shelfis, som täcker en stor del av Wedellhavet med en yta av ca 450 000 km².Båda har var för sig en yta som är ungefär som Sveriges yta.

The Space Launch System (abbreviated as SLS) is an American super heavy-lift expendable launch vehicle under development by NASA since 2011. As of March 2022, the first launch is scheduled for no earlier than May 2022, pending the success of a wet dress rehearsal test on April 3rd, 2022. It replaces the Ares I and Ares V launch vehicles, which were cancelled along with the rest of the Constellation program, a previous program aimed to return to the moon. The SLS is intended to become the successor to the retired Space Shuttle, and the primary launch vehicle of NASA's deep space exploration plans through the 2020s. Crewed lunar flights are planned as part of the Artemis program, leading to a possible human mission to Mars. The SLS is being developed in three major phases with increasing capabilities: Block 1, Block 1B, and Block 2. As of August 2019, SLS Block 1 launch vehicles are to launch the first three Artemis missions and five subsequent SLS flights are planned to use Block 1B, after which all flights will use Block 2.The SLS is planned to launch the Orion spacecraft as part of the Artemis program, making use of the ground operations and launch facilities at NASA's Kennedy Space Center in Florida. Artemis is projected to use at most one SLS each year until at least 2030. SLS will launch from LC-39B at the Kennedy Space Center.
The first launch was originally scheduled for 2016, but it has been delayed at least nine times, adding more than five years to the original six-year schedule.
