This is the third of three posts about the planetary protection workshop I attended at NASA Ames from March 24-26, 2015. The first is here. I mentioned, in my last post on forward contamination, that reverse contamination is the primary concern for Planetary Protection (PP). In this context, reverse contamination refers to the transport of Martian …
This is the second of three posts about the planetary protection workshop I attended at NASA Ames from March 24-26, 2015. The first is here (and here.) Forward contamination, in the context of planetary protection, refers to the transport of microbes from Earth to Mars. The title of the workshop, and many talk titles refer to “human …
reposted from jennomics.com http://www.nasa.gov/ames/events/ppw2015workshop/#.VRMLLJPF8mU I’m at a NASA Ames workshop this week. The goal is to have a discussion about planetary protection with respect to human spaceflight, in particular to Mars, mostly during a “sample and return” mission and a little bit about human habitation on Mars. I’m tweeting with #planetaryprotection. There’s also live streaming here: …
An important part of science is owning up to mistakes and doing the best to correct them. A couple months ago we got data from the International Space Station where we had grown up bacteria for our “Microbial Playoffs”. After analyzing the the data we blogged about the winners and disbursed the results far and …
NOTE (3-12-15): THESE RESULTS ARE INCORRECT. We have left them here for comparison. A blog post describing the problem is here and the correct information can be found here. We’ve finished analyzing all the data from the “Microbial Playoffs” part of Project MERCCURI (described here). Each microbe that was chosen to fly to the International …
Analysis of the growth data from space is ongoing but we have some preliminary results to share: Firstly, 47 of the 48 bacteria grew at least a little bit in space, the only exception was the sample collected from the Philadelphia Phillies dugout. Sorry guys! A number of the bacteria grew quite well in fact, …
After 9 months of technical delays, during which time our collection of frozen built environment microbes went around the earth every 90 minutes, we are finally getting growth data from the International Space Station (ISS)! Astronaut Terry Virts has been taking daily growth readings of our collection of 48 microbes and today (Friday) is …
For many years I have been worried about how space travel will affect microbiomes – of the space vehicles and of the residents (people, other animals, plants, etc). This is one of the reasons we started Project MERCCURI and get involved in looking at the microbes on the International Space Station. It is also why …
Well, here is another benefit of automated Google Scholar searches. I think it is unlikely I would have found these new papers without such searches but these are fascinating and directly relevant to many aspects of work we are doing on Project MERCCURI. A series of papers on microbial ecolog and space travel in the …
I’m proud to announce that the sample collection for the building science component of Project MERCCURI is complete! In early May, Koichi Wakata from JAXA (Japan’s space exploration agency) collected swabs swabs of surfaces aboard the International Space Station. Back in June last year, Jenna, Wendy and I went to the Johnson Space Center in …
