With the closing of the human spaceflight program, many people would argue that this decision is a disgrace to America and its space program. However, the United States has been very successful using robots like the Mars rovers or the Phoenix lander. There has been a shift from using astronauts to using space probes due to the rapid growth in technology. An example of this technology is the Kepler Space Telescope. Using this, scientist have been able to discover more than 500 planets in a different solar system. A probe is orbiting Mercury right now, and there is another probe that is believed to go past Pluto in 2015.
There are many arguments in favor of human spaceflight. One of the arguments Lind mentions and refutes is that machines are unable to conduct scientific experiments due to their lack of intelligence.

Lind has a very sarcastic tone in this argument, and he doesn’t give enough credit to the astronauts. In conclusion, I believe that this article is not written well, and has minuscule evidence to why spaceflight should end, which ironically is the title of the article.
