ESA, Europa, and the Moon

So now the European Space Agency wants to join NASA on its trip to Europa.  That is good for international cooperation and funding since ESA may contribute about $550 million related to a separate probe.  NASA already has about $2 billion in funding for the mission.  Alvaro Gimenez, ESA’s director of science and robotic exploration. stated:

We are ready and interested...As I said to my colleague in the U.S., we cannot allow Americans to go to Europa without Europeans. We have to be part of it. We think that it is natural, but certainly we will not lead, so we have to wait.

I am surprised since ESA has its own plans for Europa via the JUpiter ICy moons Explorer (JUICE).  Both the NASA mission and JUICE are slated for 2022.  It could make sense for ESA to contribute to the NASA mission and vice versa to double the chances that the two space agencies will get a craft to Europa.

That does not mean both space agencies see eye-to-eye on all future missions, particularly manned missions.  While NASA seems to be aiming for manned missions to Mars, the European Space Agency (ESA) is gunning for the occupation of the Moon.  In this video, Destination: Moon, ESA discusses how we have explored only a part of the Moon, highlights the need to determine how much water is really below the surface, points out the advantages of a telescope outside of Earth's interference, and recommends an international Moon base similar to the arrangement in Antarctica.

While many in the United States would say "been there, done that," ESA makes a convincing argument that more can be learned about the Moon and thereby the Earth.  This would be much better than our decades in low-Earth orbit, but not as sexy as Mars.  Maybe ESA could lead the lunar mission while NASA focuses on Mars.  Of course, with Russia and China also planning manned missions to the Moon, I expect the United States might feel left out.  But we can still be there, if only "leading from behind," with some of our heavy-lift rockets and hard-earned expertise. It has been a long time since we had astronauts on the Moon and a permanent mission sounds like a good idea for everyone involved.

Update: To be fair, ESA contributed about $470 million to the Orion service module, indicating plenty of support for a manned Mars mission. It appears ESA is hoping such support may provide a spot for a European astronaut on the trip to Mars. That is cheaper and smarter than funding a separate mission. 

Alien Ocean: NASA's Mission to Europa

NASA's Jet Propulsion Laboratory released this video on NASA's planned mission to Jupiter's moon Europa.  It discusses the space agency's plan to send a spacecraft to conduct flybys of the moon to better understand its composition, its presumed liquid water oceans, and its potential for life.  Unlike other missions that orbit the object being observed, the radiation around the moon would soon cook any nearby spacecraft.  So instead NASA hopes that multiple flybys, and even a potential fly-through of any plumes, will provide us with the necessary information to make some solid determinations about Europa. It is an ambitious plan, but as spacecraft such as Galileo, Voyager, Cassini, New Horizons, and others have proven, we are up to the task.

NASA's FY 2015 Budget Request: Good Ideas with Limited Resources

The White House released its budget request for NASA earlier in the week.  The good news is that NASA has a lot of good projects on the drawing board.  The bad news is that this country does not have the money or will power to adequately fund future space projects.  The White House asked for $17.5 billion for NASA in FY 2015, a drop from $17.6.  And while this does not sound like much, it is a much larger cut if you assume any level of inflation since the space agency again has to do more (or at least the same work) with less money. 

But let's look at the proposed projects listed in NASA's budget:

•  Supports the 2018 launch of the James Webb Space Telescope;
•  Continues formulation and development of Mars Rover 2020 and MOMA/ExoMars missions to Mars;
• Continues development of the robotic OSIRIS-REx mission to retrieve and return samples from an asteroid;
• Continues pre-formulation work for a potential mission to Jupiter’s moon, Europa. 
• Extends operation of the International Space Station (ISS) to at least 2024, and sustains delivery of cargo to the ISSwith U.S. developed, commercially procured space transportation elements;
• Maintains development of Space Launch System/Orion on track to send astronauts on deep space exploration missions; and
• Funds 7 launches over 24 months: Deep Space Atomic Clock (precise navigation); Green Propellant (higher-performing alternative to toxic hydrazine); Sunjammer Solar Sail (propellant-free propulsion); and four small spacecraft demos.

NASA also made a video explaining this budget, which is an interesting approach to the dry workings of budget policy. 

This is a promising list of projects.  Exploration of Europa is exciting, and one can argue that a lot of this work can still contribute to a manned space mission to Mars at some point in the future.  In fact, the budget PowerPoint notes that this budget "Aligns NASA’s activities to send humans to an asteroid by 2025 and Mars in the 2030s."

NASA's Administrator Charles Bolden expanded on this in his press release, stating:

In the coming year, we'll build on our nation's record of breathtaking and compelling scientific discoveries and achievements in space, with science missions that will reach far into our solar system, reveal unknown aspects of our universe and provide critical knowledge about our home planet.  It includes funding for missions to Mars and the formulation for a mission to Jupiter's moon, Europa. It also funds science missions already heading toward destinations such as Jupiter and Pluto and operating throughout the solar system, a mission to study our planet's magnetic system, and steady progress on the James Webb Space Telescope.

Could NASA use more funds for more extensive exploration?  Absolutely, but that is not in the cards with this Congress and in this economy.  And combined projects with other nations, such as China and now Russia, may be difficult to establish given the political situation.  That said, maybe now is a time to out-Putin Putin with a bold new mission in space?  This budget came too late for such vision, but I am hopeful.
