Q: How many countries are signatories of NASA’s Artemis Accords as of May 2024?

40 - NASA’s Artemis Accords are a set of voluntary intergovernmental agreements to guide peaceful and responsible exploration of the Moon, Mars, and beyond. These accords were first announced in October 2020 and have attracted numerous space‑interested countries over time. By May 2024, the number of signatory nations had reached approximately 40 countries. Specifically, Lithuania became the 40th nation to sign in mid‑May 2024 state.gov+15nasa.gov+15theguardian.com+15nasa.govtheguardian.comen.wikipedia.org. Later in May, Peru and Slovakia signed, increasing the count to around 42 by the end of the month spacepolicyonline.com+1. Thus, the best option for May 2024 is 40 signatories. Other options are not accurate: 29 or 30 are too low compared to the documented progression. “None of These” is incorrect, since the number was clearly around 40. Each country signing the Artemis Accords commits to international norms such as transparency, peaceful use of space, and open sharing of scientific data. These principles expand the United Nations Outer Space Treaty (1967), aiming to foster safer and cooperative deep‑space missions.Knowing the number of signatories by a particular time helps illustrate how quickly international support for these accords has grown. From just a handful of founding members in 2020 to dozens by mid‑2024, the Accords show the increasing global interest in collaborative space exploration. This question fits under General Science because it covers science policy and international cooperation in space—a key part of everyday scientific knowledge.
