Contact with ETI via radio and companies team up to build moon landers

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Cosmic material that has settled on the moon over billions of years could shed light on where a peculiar type of nitrogen in our solar system came from, a new study suggests. See article.
g Intelligence - Looking at the last term of the Drake Equation, we see that it relates to the lifetime of technological civilizations – how long they last as technological (meaning interstellar communicating) entities. The three biggest considerations for our civilization at the moment could be characterized as a) getting along with each other, b) getting along with the environment, and c) staying technologically alert for large-scale concerns from space. As an example of the last, the dinosaurs had over 200 million years to develop a comet deflector, but never did so. Some dinosaurs were bipedal, had opposable claws, and were pretty intelligent—so why didn’t they, for example, invent space travel? Well, that’s a topic for another essay. Meanwhile, let’s stick to a few of the things we might want to deal with “out there” at various times in the future, from a few thousand to a few billion years from now. See article. Note: This article is from 2005.
g Message - Visiting another civilization on a distant world would be fascinating, but at present such a trip is beyond our capabilities. However, it is perfectly within our capabilities to develop a communications system using a powerful transmitter and a sensitive receiver, and using it to search the sky for alien worlds whose citizens have a similar inclination. See article.
g Cosmicus - Two California companies, one a rocket engine builder and the other a mock moon lander champion, have teamed up to develop new private unmanned vehicles that NASA could send to the moon, Mars and asteroids. See article.
g Learning - Although it defaults to Norway, aspiring space explorers at Stig’s Sky Calendar can pick their (or their closest) international city to see what sights they can expect for almost any month in the past, present, or future.
