Prometheus Being Chained by Vulcan by Dirck van Baburen, 1623, Museum of the Netherlands

Prometheus stole fire from the gods and gave it to mankind. As punishment, Vulcan chained him to a rock, where an eagle pecked out his liver causing him excruciating pain. Here we see Prometheus being chained, his face contorted with fear, while Mercury laughs at him. Van Baburen borrowed the dramatic illumination and the figure’s sunburned hands and faces from his great model Caravaggio.

One Year Into Our Planet-Hunting TESS Mission

Our Transiting Exoplanet Survey Satellite (TESS), launched last year on April 18, is completing a year in space, surveying the skies to find the closest, most exciting planets outside our solar system for further study. Worlds that TESS is hunting for include super-Earths, rocky planets, gas giants, and maybe even some Earth-sized planets — and much, much more! TESS is scanning the whole sky one section at a time, monitoring the brightness of stars for periodic dips caused by planets transiting (that is, passing in front of) those stars. So far, TESS has found 482 candidates and 10 confirmed exoplanets.

Since its launch, TESS has orbited Earth a total of 28 times. TESS has a unique elliptical orbit that circuits around Earth twice every time the Moon orbits. This allows TESS’s cameras to monitor each patch of sky continuously for nearly a month at a time. To get into this special orbit, TESS made a series of loops culminating in a lunar gravitational assist, which gave it the final push it needed.

Did you know that TESS has some serious mileage? The spacecraft has traveled about 20 million miles so far, which works out to an average of about 2,200 miles per hour. That’s faster than any roadrunner we’ve ever seen! This would be four times faster than an average jet. You’d get to your destination in no time!

TESS downloads data during its closest approach to Earth about every two weeks. So far, it has returned 12,000 gigabytes of data. That’s as if you streamed about 3,000 movies on Netflix. Get the popcorn ready! If you total all the pixels from every image taken using all four of the TESS cameras — which is about 600 full-frame images per orbit, you’d get about 805 billion pixels. This is like half a million iPhone screens put together!

When the Kepler Space Telescope reached the end of its mission, it passed the planet-finding torch to TESS. Where Kepler’s view was deep — looking for planets as far away as 3,000 light-years — TESS’s view is wide, surveying nearly the entire sky over two years. Each sector TESS views is 20 times larger than Kepler’s field of view.

TESS will continue to survey the sky and is expected to find about 20,000 exoplanets in the two years it’ll take to complete a scan of nearly the entire sky. Before TESS, several thousand candidate exoplanets were found, and more than 3,000 of these were confirmed. Some of these exoplanets are expected to range from small, rocky worlds to giant planets, showcasing the diversity of planets in the galaxy.

The TESS mission is led by MIT and came together with the help of many different partners. You can keep up with the latest from the TESS mission by following mission updates and keep track of the number of candidates and confirmed exoplanets.

Your Gut in Space

Finding the Right Balance for the Microbiota

Trillions of microorganisms live on and in the human body, many of them essential to its function and health. These organisms, collectively known as the microbiota, outnumber cells in the body by at least five times. 

Microorganisms in the intestinal tract, the gut microbiota, play an especially important role in human health. An investigation on the International Space Station, Rodent Research-7 (RR-7), studies how the gut microbiota changes in response to spaceflight, and how that change in turn affects the immune system, metabolic system, and circadian or daily rhythms. 

Research shows that the microbiota in the mammalian digestive tract has a major impact on an individual’s physiology and behavior. In humans, disruption of microbial communities has been linked to multiple health problems affecting intestinal, immune, mental and metabolic systems.

The investigation compares two different genetic strains of mice and two different durations of spaceflight. Twenty mice, ten of each strain, launch to the space station, and another 20 remain on the ground in identical conditions (except, of course, for the absence of gravity). Mice are a model organism that often serves as a scientific stand-in for other mammals and humans. 

Fecal material collected from the mice every two weeks will be examined for changes in the gut microbiota. Researchers plan to analyze fecal and tissue samples after 30 and 90 days of flight to compare the effects of different durations of time in space. 

With a better understanding of relationships between changes such as disruption in sleep and an imbalance of microbial populations, researchers can identify specific factors that contribute to changes in the microbiota. Further studies then can determine proactive measures and countermeasures to protect astronaut health during long-term missions.
