We understand and respect the points raised by Rummel and Conley (2017) in response to our initial Forum Article (Fairén et al., 2017), which we acknowledge are informed and literate. Unfortunately, they are also unconvincing. Their comments clearly illustrate why we are not searching for life on Mars today and why we haven’t done so during the last decades. Hereafter, we respond point by point...

A delay would add millions to the cost of the mission, disrupt the intricate space shuttle schedule, and anger researchers eager to do science. But as the long-time program scientist of the Hubble Space Telescope effort, whose faulty mirror had to be corrected in space, Weiler knew that haste might have even more serious consequences. His instincts told him to wait. “I overruled three independe...
