Opportunity rover’s path on Mars

After a most unforgiving dust storm on Mars, NASA ended the 14-year mission with the Opportunity rover. It was originally only planned to last 90 days. Jonathan Corum, for The New York Times, mapped the little guy’s journey over the years.

The cancer moonshot and other future science fantasies

Last Friday, On Science Blogs was given over to the many “best of science” lists of 2015. This week’s post is about what bloggers foresee for 2016–and beyond. THE CANCER MOONSHOT: WELCOME TO 2016 Vice-President

Again, water on Mars. Also abortion, Planned Parenthood, fetal tissue research

WATERY MARS AGAIN Emily Lakdawalla thinks everybody should calm down about NASA’s much-trumpeted latest discovery of liquid water on Mars. The discovery, which is probably not flowing water but rather something more like damp sand, doesn’t, she argues at the … Continue reading »

Science for the People: Impossible Space

sftpThis week Science for the People is exploring the limits of science exploration in both fictional and fact. We’re joined by “lifelong space nerd” Andy Weir, to talk about his debut novel The Martian (and soon to be film, trailer below), that pits human invenitveness and ingenuity against the unforgiving environment of the red planet. And astrophysicist and science blogger Ethan Siegel returns to explore so-called “impossible space engines“, and what news stories about them can teach us about journalism and science literacy.

Epigenome Project, robot ethics, one-way trip to Mars

  Here’s the Epigenome Project The headline on Rachel Feltman’s post at Speaking of Science said the epigenome project was awesome, which is as good an introduction as any. That slew of two dozen papers in Nature and its associated … Continue reading »

UC Davis MARS Symposium Wrap Up #globalfood #UCDavisMARS

Yesterday I went to a symposium at UC Davis that was the launching of a new partnership between UC Davis and the Mars Corporation. I note - I have been collaborating with some people at Mars on multiple microbiome related projects and generally have had great interactions with the people there. I am not directly involved in the planning for this new partnership between UC Davis and Mars and thus I was interested in hearing more about it at the symposium.

The symposium was at the Mondavi Center on UC Davis campus and I zipped in on my bike through the cold (for Davis) air and got there just before they opened the doors to the main theater. I saw a few folks I knew milling around in the lobby and said hello and then went inside with some people from my lab for the "show".

 I will try to write more about this later but just one note - I found some of the big picture discussions about the importance of the nexus between food, agriculture and health to be pretty inspiring. For now - I hope the Storify I made and embedded below will give some idea as to the goings on of the symposium.

H. floresiensis or H. sapiens with Down syndrome? Plus landing on a comet

Lords of the zings

I don’t know why the new papers about the “hobbit,” the 2003 find of tiny ancient bones from the Indonesian island of Flores, have made such a splash. No, I take that back. I do know. …

Geologic map of Mars

The USGS released a more detailed geologic map of Mars, not just renderings based on rough models.

The USGS-led mapping effort reveals that the Martian surface is generally older than previously thought. Three times as much surface area dates to the first major geologic time period - the Early Noachian Epoch - than was previously mapped. This timeframe is the earliest part of the Noachian Period, which ranges from about 4.1 to about 3.7 billion years ago, and was characterized by high rates of meteorite impacts, widespread erosion of the Martian surface and the likely presence of abundant surface water.

Nice.

NASA personnel ignore planetary protection guidelines and risk putting microbes on Mars

Many years ago I served on a NASA sponsored committee for a series of meetings about the handling of samples collected from Mars.  One of the key points of discussion at those meetings was "planetary protection".  The involved protecting Earth from possibly strange life forms that in theory could exist on Mars.  And it also involved protecting Mars from microbes and other life forms that could come from space ships/landers.  I even posted all the materials from these meetings a few weeks ago: Notes and materials from MARS Sample Handling Workshops 2000 ....

It is thus with great distress that I read an LA Times article that reveals that some of the people involved in launching Curiosity decided to ignore some of the planetary protection guidelines and made some hands on modifications that may have contaminated some of the drill bits on Curiosity with microbes from people.  See: If the Mars rover finds water, it could be H2 ... uh oh! - latimes.com.

The LA Times reports that some NASA personnel opened a box of drill bits that had been sterilized and - in clean but not sterile conditions - installed one of these drill bits in a drill on Curiosity prior to launch.  Apparently they were worried that a rough landing could prevent the bits from being installable in the drill which would make the drill not be of any use.  And they appear to have now risked the sterility of the entire operation by doing this.  Well crap.  That just plain sucks.  So much effort by "planetary protection officers" and others.  That effort might all go down the drain because of this.  I get that some times things seem urgent and that sure - if the drill was useless people would be pretty upset too.  But this seems to me to be a serious error in judgement.

In a small way I helped develop the guidelines that were put in place to protect Mars from human induced contamination.  And now that seems to have been a wasted effort as the guidelines were ignored.  Not good.

Note - for those interested I have posted links below to the documents from my days at the NASA Mars Sample Handling Workshops.  Most/all are public domain materials but not all are easy to find so I thought I would post them here.  Note – I have done no clean up of scans – will do so at some point. Enjoy


UPDATE 9/13 - some more stories on this
UPDATE 2: 9/13 - UC Davis Prof. Dawn Sumner (who is involved with the Curiosity mission) disputes notion that opening the drill bit box is an issue
