You\u2019re indoors, working on a job application. Outside, there are voices and cars, the broad blue of the San Francisco Bay, and \u2013 a few hundred kilometres up \u2013 the silence of low Earth orbit. At that altitude, there\u2019s not much: some tenuous air, the occasional piece of space debris, and a lone space station \u2013 Mir. Inside, an astronaut drifts over to inspect some wheat seedlings growing in a small steel chamber under artificial light. These plants will help determine whether humans on long-term exploration missions might one day feed themselves by growing crops in space.<\/p>\n\n\n\n<p>For now, you have more worldly concerns. You need to feed yourself and your young family \u2013 not by growing crops in space, but by finding a job on Earth. The position you\u2019re applying for is at NASA, where big things are in progress. Some 3,000 km to the east of you in Huntsville, Alabama, work is being completed on the Unity module \u2013 the first US-built component of what will become the International Space Station (ISS). When Unity is launched and joined to the Russian Zarya module later in the year, the ISS \u2013 and its programme of scientific research \u2013 will start to become a reality. A job at NASA ought to be an exciting prospect, but somehow you\u2019re not convinced it\u2019s the right thing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Problems on Earth<\/h2>\n\n\n\n<p>That was the situation for EMBL alumna Sigrid Reinsch in the spring of 1998, when she was coming to the end of a postdoc position at EMBL in Heidelberg. After six years living in Germany, she was looking for a job back in her home country. \u201cI applied for tons of university positions in the US and none of the applications worked out,\u201d she says. \u201cI ended up going on a US tour and trying to figure out what other types of jobs I could do. In desperation, I was hanging out in a friend\u2019s office in San Francisco and she told me about this job at NASA.\u201d<\/p>\n\n\n\n<p>At that time NASA was looking to expand its space biology programme, a major component of which is research relating to long-duration spaceflight. This includes experiments to determine the effects of radiation exposure or weightlessness on humans and other organisms. Most of NASA\u2019s space-borne biological experiments were being carried out on Mir and on Space Shuttle missions, gradually transferring to the ISS following the arrival of the first crew in 2000, the deorbit of Mir in 2001, and the end of the Space Shuttle programme in 2011. When Reinsch was applying for a job in 1998, NASA was aiming to recruit more scientists with training in cell and developmental biology.<\/p>\n\n\n\n<blockquote class=\"vf-blockquote\"><p>EMBL was like the Disneyland of biology: any experiment you could think of, you could do<\/p><\/blockquote>\n\n\n\n<p>The position she applied for was for someone with experience of research on the cytoskeleton \u2013 the network of protein filaments and tubules that gives cells their structure, and which is involved in processes like organising the cell\u2019s contents, cell migration, and cell division. The cytoskeleton had been the subject of Reinsch\u2019s PhD and her subsequent postdoctoral work in <a href=\"https:\/\/www.embl.de\/research\/units\/directors_research\/karsenti\/index.html\">Eric Karsenti\u2019s group<\/a> at EMBL, so she decided to apply. She was keen on the biological research aspect of the job, but had no particular interest in spaceflight experiments. \u201cI felt very strongly that we have enough problems on Earth that we should focus on,\u201d she recalls, \u201crather than doing experiments in space.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Reorientation<\/h2>\n\n\n\n<div class=\"wp-block-image vf-u-width__30\"><figure class=\"vf-figure  | vf-figure--align vf-figure--align-inline-start  \"><a href=\"https:\/\/news.embl.de\/wp-content\/uploads\/2017\/11\/171122-Sigrid_Reinsch.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"286\" height=\"300\" class=\"vf-figure__image\" src=\"https:\/\/news.embl.de\/wp-content\/uploads\/2017\/11\/171122-Sigrid_Reinsch-286x300.jpg\" alt=\"EMBL alumna Sigrid Reinsch.

PHOTO: NASA\/Dominic Hart<\/figcaption><\/figure><\/div>\n\n\n\n<p>Almost twenty years after accepting a job offer from NASA,&nbsp;things are a little different. \u201cMy opinion has changed,\u201d says Reinsch with a smile. Initially her work at NASA involved research on the clawed frog <em>Xenopus<\/em>, an important model organism in biological studies. This included research on the development and functioning of the vestibular system \u2013 that part of the inner ear that assists with balance and spatial orientation, and which is often disturbed in conditions of weightlessness. Later she worked on projects focusing on the development of biofuels, which NASA is considering as a possible energy source for long-term human space exploration. Since 2014 she\u2019s been involved in the <a href=\"http:\/\/genelab.nasa.gov\/\" target=\"_blank\" rel=\"noopener noreferrer\">GeneLab<\/a> project, which aims to maximise the scientific return from experiments carried out on the ISS. \u201cThe purpose of GeneLab is to get the biggest bang for the buck out of any spaceflight experiment,\u201d Reinsch explains. \u201cWe don\u2019t change the funded, peer-reviewed proposal for an experiment but we investigate whether we could carry out additional analyses or add components to augment the experiment in some way.\u201d<\/p>\n\n\n\n<p>An important component of GeneLab is an open access database to house various types of biological data, not only from spaceflight experiments but also from ground-based experiments with important implications for space research, such as experiments that simulate weightlessness or study the effects of radiation. \u201cThe database is very easy to use,\u201d says Reinsch, \u201cand it\u2019s designed to encourage collaboration between research groups.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Taking on tardigrades<\/h2>\n\n\n\n<p>While much of Reinsch\u2019s early career involved research on frogs, she\u2019s recently branched out into working with various invertebrate species, including tardigrades. These are microscopic creatures typically less than a millimetre long that live in almost every environment on Earth, including deserts, the deep sea, and the poles. They\u2019re famous for being able to enter a state of suspended animation by vastly reducing the water content of their bodies. This allows them to survive extreme conditions including temperatures just a degree above absolute zero and higher than the boiling point of water, pressures many thousands of times higher than atmospheric pressure, and radiation levels that would be fatal to most animals. They\u2019re also the only animal to have survived the vacuum of space, as demonstrated in <a href=\"http:\/\/dx.doi.org\/10.1016\/j.cub.2008.06.048\">an experiment carried out by the European Space Agency<\/a> (ESA) in 2007.<\/p>\n\n\n\n<p>This extreme resilience, and the biological mechanisms behind it \u2013 such as an ability to protect DNA from radiation damage, or repair it afterwards \u2013 make tardigrades an interesting animal for scientists seeking a way to help humans and other organisms tolerate long-duration spaceflight. An understanding of the limits of endurance of terrestrial organisms can also assist astrobiologists in identifying places to search for life in other parts of the solar system.<\/p>\n\n\n\n<div class=\"wp-block-image size-full wp-image-11538 vf-u-width__30\"><figure class=\"vf-figure  | vf-figure--align vf-figure--align-inline-start  \"><a href=\"https:\/\/www.embl.org\/news\/wp-content\/uploads\/2017\/11\/171122-science-in-space_1.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"425\" class=\"vf-figure__image\" src=\"https:\/\/news.embl.de\/wp-content\/uploads\/2017\/11\/171122-science-in-space_1.jpg\" alt=\"Tardigrades are the only known animal to have survived the vacuum of space.

In this ground-based microscope image, a tardigrade\u2019s recent meal of green algae is visible through its transparent body. PHOTO: Sigrid Reinsch<\/figcaption><\/figure><\/div>\n\n\n\n<p>Reinsch\u2019s work with tardigrades came about when she was asked to explore alternative uses for a piece of ESA-designed hardware known as the European Modular Cultivation System (EMCS). Reinsch and her colleagues demonstrated that the EMCS \u2013 originally designed for plant growth experiments \u2013 could successfully support a range of other organisms including bacteria, brewer\u2019s yeast, <em>Dictyostelium<\/em> (a type of slime mould), nematode worms, and tardigrades. \u201cThat\u2019s how I got into working with tardigrades,\u201d she explains, \u201cby taking this cool piece of hardware and saying, \u2018OK, besides plants, what else can we use it for?\u2019\u201d<\/p>\n\n\n\n<p>Reinsch is currently technical monitor for another experiment involving tardigrades, led by Tom Boothby at the University of North Carolina. Boothby\u2019s experiment will monitor both immediate and long-term changes in gene activity over several generations of tardigrades living on the ISS. The hope is that understanding the genetic changes that allow tardigrades to cope with the stresses of spaceflight will help in developing methods for humans to more safely spend prolonged periods in space.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A different kind of science<\/h2>\n\n\n\n<p>Research in space presents many challenges. The chemicals that might be used in a typical lab experiment are not all approved for experiments on the ISS, and many levels of containment are required to ensure that chemicals can\u2019t escape. And something as simple as liquid transfer becomes a major problem. \u201cIn microgravity, a droplet won\u2019t drop into a container, so you need a syringe-like apparatus to transfer liquids,\u201d explains Reinsch. \u201cSpaceflight experiments also have to be very minimalistic. The astronauts on the ISS don\u2019t have a lot of time to devote to experiments, so in large part the experiments have to be able to run themselves. You also have a limited number of samples and you don\u2019t get a chance to run the same experiment multiple times. You really have to plan effectively and anticipate any problems that might occur.\u201d<\/p>\n\n\n\n<p>For Reinsch, this approach to science has definitely required some adjustment. \u201cI had a great time working at EMBL. To me, it was like the Disneyland of biology \u2013 any experiment you could think of, you could do,\u201d she says. \u201cWith spaceflight research there are all these extra constraints you have to deal with. I\u2019ve had to learn how to do science in a very different way.\u201d<\/p>\n\n\n\n<blockquote class=\"vf-blockquote\"><p>Studying life is really wonderful and always continues to astound me<\/p><\/blockquote>\n\n\n\n<p>When asked if she\u2019d like to be one of the astronauts up there doing experiments, Reinsch remains practical. \u201cIn my mind, yes; in my body, no. I have problems just going on a boat, so I think I\u2019d find it difficult dealing with the disorientation of being in space. Also, the fluids in your body migrate upwards because they\u2019re not pulled down by gravity, so you have a lot more fluid in your head than you\u2019re used to. I\u2019m already prone to headaches so I think that would be a really bad idea for me,\u201d she explains. \u201cBut if I could go and not have any of those physical problems, of course I\u2019d love to. It would be very cool.\u201d<\/p>\n\n\n\n<p>Despite her initial scepticism about spaceflight research, Reinsch is now enjoying the role she plays in getting the best science from the ISS, and is keen to see what discoveries will emerge. \u201cThere are so many things I want to know, let me tell you,\u201d she says. \u201cMy curiosity is hard to corral, and NASA is a great place for someone with a curious mind. Studying life is really wonderful and always continues to astound me. Getting to do that is the best thing that could ever happen to me.\u201d<\/p>\n\n\n<div class=\"vf-box vf-box--normal vf-box-theme--primary\">\n<p class=\"vf-box__text\" class=\"p1\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-9449 alignleft\" src=\"https:\/\/news.embl.de\/wp-content\/uploads\/2017\/10\/Curiosity_150x150.jpg\" alt=\"\" width=\"150\" height=\"150\"\/>Curiosity is a profoundly human trait.
