A New Statement on NASA's 2020 Rover Mission

A collaborative effort with various scientific organizations to emphasize a balanced program of exploration

This morning The Planetary Society released an official statement regarding NASA's new Mars rover mission – slated to launch in 2020 – and how it fits into the goals of the scientific community.

I had the pleasure of working on this statement with members of several scientific organizations, including the American Astronomical Society's Division for Planetary Science and the American Geophysical Union Planetary Science Section. They will all release similar statements over the next few days, but the general gist will be the same: a balanced program of solar system exploration is crucial, and the only way to get there is via a slight increase in funding to NASA's Planetary Science Division.

The Society is working hard to emphasize the "balanced" part of that statement, which means missions to varied targets, as well as research funding for scientists and technology development that will ensure access to inhospitable planetary environments in the future.

In this statement, we mention something called the Decadal Survey a lot. The Survey, or "the Decadal" for those not up to date on the latest planetary science community lingo, represents the official consensus of the scientific community about mission priorities for the decade spanning 2012 - 2022. Now when I say "official consensus," I don't mean that every single scientist agrees with the report, not by a long shot. But it does provide a pretty decent representation of the planetary science community's priorities as a whole, and is the end result of a long process with deep community involvement. You can read the whole 410 pages here, or (like many people) choose the more concise executive summary. It was created to help guide Congress, the Administration, and NASA when they make decisions regarding funding and mission selection. It's not holy writ, but it is important and helps prevent a fractured, divisive battle for funding within the scientific community.

The Planetary Society, like the scientific organizations listed earlier, supports the priorities of the Decadal Survey. The first priority is a flagship (i.e. expensive) mission to Mars to collect samples for eventual return. A mission to Europa is a close second flagship mission recommendation. Maintaining funding for small missions, (a.k.a. Discovery-class missions), is considered as important as any flagship. So is maintaining research funding for scientists and funding technology development. This is a long-winded way of saying that the Decadal emphasizes a balanced program, and so do we.

The problem is, of course, that it's difficult to support a balanced program when funding gets cut by 21%. That's why we've been running our Save Our Science campaign for the past year, and are working hard to ensure that NASA has the resources to enable this unprecedented – and surprisingly affordable – program of exploration in our solar system.

Go ahead and read our statement. I welcome discussion below in the comments or via email.

Speaking of Mars missions: this proposed Mars sample-return mission has me a bit worried. If we are really going to do this sample-return, let's use the ISS for sample-return analysis. We have an orbiting lab, let's use it.

@changcho That would be cool, wouldn't it? I'm guess that a sample return spacecraft re-entry may be actually easier than getting it into an orbit where it could safely dock with the ISS. There will also be major steps taken to ensure that the samples do not contaminate (or are themselves not contaminated by) their surroundings. That fact alone may put the astronauts on the ISS in too much risk for this to be considered.

Here is a searched links for result on forward and backward contamination. NASA is updating this now with newer technology (see the listed article). Other articles are worth the look at. The 1967 International Agreement is also discussed on one of the links. Goto:
