Messaging to Extraterrestrial Intelligence (METI): An Objective Analysis of Pros and Cons

Messaging to Extraterrestrial Intelligence (METI), also known as Active Search for Extraterrestrial Intelligence (SETI), is an approach that involves broadcasting intentional signals into space in the hope that an alien civilization might detect and respond to them. This strategy differs from passive SETI, which focuses on listening for signals rather than transmitting them. While the potential benefits of METI are profound, so too are the potential risks. This article provides an objective review of its pros and cons.

Time in Space: A Review of Typical Milestones and NET/NLT Designations in Space Projects

Timing is paramount, particularly in the sphere of space exploration. Each mission can be likened to a complex puzzle, requiring each piece to slot perfectly into place for the broader picture to emerge. To ensure all parts align just right, there are two significant types of checkpoints used: ‘No Earlier Than’ (NET) and ‘No Later Than’ (NLT). These terms effectively bracket the ‘earliest’ and ‘latest’ dates for task completion. This article reviews these critical markers relative to their importance in maintaining the timely progression of space missions and ensuring the successful attainment of their objectives.
