NASA and ESA join forces to build life-seeking Europa lander

https://www.newscientist.com/article/2128751-nasa-and-esa-join-forces-to-build-life-seeking-europa-lander/

The headline is misleading. It states that NASA and ESA have already done this. But the article indicates that this was a proposal at a science meeting.

Why don't you take that up with SN as they are the people linking to the article where I got it from.

http://spacenews.com/scientists-want-nasa-and-esa-to-work-together-on-a-europa-lander-mission/

Space News has a correct headline: "Scientists want NASA and ESA to work together on a Europa lander mission." That is accurate.

This New Scientist headline is inaccurate: "NASA and ESA join forces to build life-seeking Europa lander."

This Futurism headline is truly horrible: "Itís Official. In 2025, NASA and the ESA Will Land on Europa to Look For Alien Life"

The Space News short blurb is by Jeff Foust. I've known Jeff for about 15 years now. Jeff has a Ph.D. in planetary sciences from MIT. His writing is almost always very accurate. And he is very careful with interpreting his sources.

I am sure SN is fine but my point is they linked to the article & therefore promoted it to their readership.

I like the headline. It's so unashamed in its beyond-wrongness.

It's almost like the job of the media is to sell, not be truthful or accurate.

Well, we expect greater accuracy from the trade press. Why is New Scientist so sloppy?

In my experience, New Scientist generally is pretty solid although they tend towards solid coverage of somewhat more sensational stories.  In some cases the reporting is sloppy.  My guess is that someone with no understanding of how missions actually get approved was handed a press release or the equivalent.

New Scientist is fond of stories about very speculative theories. To their credit, they usually at least include a sceptical comment from some expert who is not directly involved in the work. Even in their news article they like to emphasise the sensational part  (there's always a miracle cure found or some impeding catastrophe is threatening), though they don't usually get things as clearly wrong as in this case.

New Scientist was really bad a few years ago, but they've maybe toned down their sensationalism a bit lately.

I am a regular reader and find that news pieces usually include a counter view to a varying extent. Not sure what happened with that headline as that was below their usual standards. Hopefully someone will flag it up in their letters page where you often get things like this that they are pulled up on.

Another example of a clickbait headline. You can read it in the url:

http://www.independent.co.uk/news/science/cassini-spacecraft-nasa-loses-contact-dive-through-saturns-rings-grand-finale-a7703616.html

You can find loads of examples of such things online, so I am not sure what kind of point you're trying to prove here?

Here's the relevant section.

NASA receives more than $19.6 billion in 2017 omnibus spending bill

Quote
That planetary science funding also includes $275 million for Europa missions, both the Europa Clipper multiple flyby spacecraft and a proposed lander. Language in the bill requires NASA to launch Europa Clipper no later than 2022 and the lander no later than 2024, although NASA officials have recently said they donít expect the lander mission to be ready for launch until at least 2025. The Trump administrationís 2018 budget blueprint supported Europa Clipper but included no funding for a Europa lander.

The sounds of Europa

Quote
Although there are no plans at present to send a lander to Europa, we continue to work on the prospects, asking what kind of operations would be possible there. NASA is, for example, now funding a miniature seismometer no more than 10 centimeters to the side, working with the University of Arizona on a project called Seismometers for Exploring the Subsurface of Europa (SESE). Is it possible our first task on Europaís surface will just be to listen?

The prospect is exciting because what weíd like to do is find a way to penetrate the surface ice to reach the deep saltwater ocean beneath or, barring that, any lakes that may occur within the upper regions of the ice shell. The ASU seismometer would give us considerable insights by using the movements of the ice crust to tell us how thick it is, and whether and where ocean water that rises to the surface can be sampled by future landers.

Quote
Seismometers would help us detect ongoing activity in the shell. ASU envisions a seismometer mounted on each leg of a lander ó four to six seismometers in all, depending on lander design. These would be driven deep into the ground, avoiding the kind of loose surface materials that would isolate the instruments from seismic waves passing through the shell. And that calls for the kind of rugged instrument ASU is building. Able to operate at any angle, the prototype can survive landings hard enough to ensure deep penetration for each seismometer.

You can find the Europa program in the NASA budget proposal. Somebody with more energy than I can cut it down to only the relevant parts and post them here.
