What lies beneath the cracked, thick ice on the surface of Europa? NASA is hoping to fly a mission to the Jupiter moon in the coming years to see if it is indeed a promising site for life. If this concept is approved in the budget, think of the mission as a recce: NASA will either orbit the moon, or do several flybys on it, to scout the surface for science and potential landing sites.
NASA just announced its desire to have science instruments proposed for the mission. Of the submitted list, 20 proposals will be selected in a year’s time, when selectees will have $25 million to do a more advanced concept study.
“The possibility of life on Europa is a motivating force for scientists and engineers around the world,” stated John Grunsfeld, associate administrator for NASA’s science mission directorate. “This solicitation will select instruments which may provide a big leap in our search to answer the question: are we alone in the universe?”
The Europa mission is not a guarantee, and it’s unclear just how much money will be allocated to it in the long run. (NASA has requested $15 million in fiscal 2015 for the mission). The mission is also subject to budgetary approvals from Congress. If it passes all obstacles, it would fly sometime in the 2020s, according to information released with the budget earlier this year.
In April, NASA sent out a request for information to interested potential participants on the mission itself, which it plans to cost less than $1 billion (excluding launch costs).
“Recent NASA studies have focused on an orbiter mission concept and a multiple flyby mission concept as the most compelling and feasible,” the agency stated.
Besides its desire to look for landing sites, NASA said the instruments should also be targeted to meet the National Resource Council’s (NRC) Planetary Decadal Survey’s desires for science on Europa. In NASA’s words, these are what those objectives are:
Any instruments must meet NASA’s landing scout goal or the NRC goals, the agency said. The instruments also must be highly protected against the harsh radiation in the area, and also meet planetary protection requirements to ensure no extraterrestrial life is contaminated with our own.
Just yesterday (July 15), a NASA symposium on extraterrestrial life included a musing that the agency’s unflown next-generation rocket could send a Europa mission there in three years instead of the expected seven. That said, the Space Launch System is not tested in space and it is unclear what the budgetary environment for the rocket would be in the coming years.
