Sunita Williams demonstrates students how astronauts drink liquid in space

A few years ago, biomedical scientist Jonathan Tsui flew to Florida with unique baggage. He toted compact chambers—smaller than a cell phone—containing 48 bits of human heart tissue. Tsui brought the samples to NASA’s Kennedy Space Center, where in March 2020 they were loaded onto a SpaceX craft and sent to the International Space Station for a month. The goal? To study the effects of low gravity conditions on the human heart in preparation for long-term space travel.

Study: Microgravity Leads to Irregular Heartbeats in Space

<p>Scientists have successfully detected the pull of gravity on the microscopic scale, setting the foundation for further exploration of its nature within the interesting quantum realm.</p>

<p>In a recent study, scientists from Leiden University in the Netherlands and the Institute for Photonics and Nanotechnologies in Italy devised a method to measure subtle gravitational forces between minuscule objects.</p>

<p>The experiment, meticulously shielded against vibrations, involved levitating a magnetic particle above a superconductor at near absolute zero.</p>

<p>In a&nbsp;breakthrough for space plant research, first plant transplant has taken&nbsp;place in the International Space Station's&nbsp;Vegetable Production System (Veggie)&nbsp;facility.</p>

<p>NASA researches crop production in space because plants can provide nutrients to astronaut crews on long-duration missions, such as a mission to&nbsp;Mars.</p>

<p>NASA astronaut Mike Hopkins, an&nbsp;Expedition 64 crew member,&nbsp;who arrived to the station for a six-month science mission aboard the SpaceX&nbsp;Crew-1&nbsp;mission, tended&nbsp;different varieties of mustards and lettuces in&nbsp;VEG-03I.</p>

<p>He noticed the mustards were growing fine in their special “pillows” containing clay-based growth media and fertilizer.&nbsp;</p>

<p>Two plant pillows containing ‘Outredgeous’ Red Romaine and ‘Dragoon’ lettuce seeds were germinating slowly, growing well behind the other plants.

<p>The transplants – ‘Red Russian’ kale and ‘Extra Dwarf’ pak choi – are surviving and growing along with the donor kale and pak choi. The remaining red romaine lettuce and “Wasabi” mustard in the experiment are also ready for harvest.</p>

<p>“This experiment is just really amazing; it shows the skill of the astronauts, the care that they take to do things, and also the differences that you see in microgravity,” Veggie Program Plant Scientist Gioia Massa said. “Fluids behave very differently in space than on the ground.

<p>“We’re used to microgravity working against us in the fluids/physics department, making growing plants in space very difficult,” Matt Romeyn, VEG-03I science lead said. “So to have an exception like this, where microgravity appears to be helpful and the plants are growing better than on Earth … that’s astonishing.”</p>
