In microgravity, without the continuous load of Earth’s gravity, the tissues that make up bones reshape themselves. Bone cells readjust their behaviors—the cells that build new bone slow down, while the cells that break down old or damaged bone tissue keep operating at their normal pace so that breakdown outpaces growth, producing weaker and more brittle bones. For every month in space, astronauts’ weight-bearing bones become roughly 1% less dense if they don’t take precautions to counter this loss. Muscles, usually activated by simply moving around on Earth, also weaken…

Ham Radio in Space: Engaging with Students Worldwide for 40 Years
In May 2018, a student at Mill Springs Academy in Alpharetta, Georgia, Andrew Maichle, talked to NASA astronaut Scott Tingle on the International Space Station via amateur or ham radio. The experience profoundly affected Maichle, who went on to study electrical engineering at Clemson University in South Carolina. “It was so cool to see in real time the utmost levels of what people in science are able to accomplish, and to talk to and interact with someone at that level,” Maichle recalls. “The space station is an incredible work of…

4 min read NASA Orbiter Snaps Stunning Views of Mars Horizon This unusual view of the horizon of Mars was captured by NASA’s Odyssey orbiter using its THEMIS camera, in an operation that took engineers three months to plan. It’s taken from about 250 miles above the Martian surface – about the same altitude at which the International Space Station orbits Earth. NASA/JPL-Caltech/ASU The Odyssey orbiter captured clouds and dust in the Red Planet’s skies, along with one of its two tiny moons. Astronauts often react with awe when they…

7 min read NASA’s Cold Atom Lab Sets Stage for Quantum Chemistry in Space This animation depicts six finely tuned lasers used inside NASA’s Cold Atom Lab to slow down atoms, lowering their temperature. Scientists can now use the lab to see how different types of atoms interact with each other at these cold temperatures. NASA/JPL-Caltech The remotely operated facility aboard the International Space Station has created another tool that researchers can use to probe the fundamental nature of the world around us. For the first time in space, scientists…

Read MoreInvestigations launching aboard SpaceX-29 will help humans go farther and stay longer in space
The SpaceX-29 commercial resupply spacecraft will deliver numerous physical sciences and space biology experiments, along with other cargo, to the International Space Station. The research aboard this resupply services mission will help researchers learn how humans, and the plants needed to sustain them, can thrive in deep space. The biological and physical sciences investigations headed to the Space Station are: Plant Water Management-5 and 6 (PWM-5 and 6) NASA has grown plants on the Space Station even without the help of gravity. But microgravity does present challenges and affects Space…
