Back in August, the crew of the International Space Station (ISS) was surprised to learn that a leak was responsible for a slight loss in air pressure aboard the station. After investigating, they learned that the cause was a small hole in the Russian Soyuz spacecraft that had docked with the ISS. While the hole was promptly sealed, the cause of it has remained a mystery ever since.
Ever since astronauts began going to space for extended periods of time, it has been known that long-term exposure to zero-gravity or microgravity comes with its share of health effects. These include muscle atrophy and loss of bone density, but also extend to other areas of the body leading to diminished organ function, circulation, and even genetic changes.
The International Space Station is officially home to the coolest experiment in space.
NASA's Cold Atom Laboratory (CAL) was installed in the station's U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These "BECs" reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. This is the first time BECs have ever been produced in orbit.
NASA astronaut Scott Kelly recently spent one year in space, while his identical twin brother Mark (a former NASA astronaut himself) stayed on Earth. The mission was part of an important health experiment, looking at how being in space affects our bodies. While the data are still being studied carefully, NASA recently released some intriguing preliminary findings.
I’m very excited about seeing Rogue One: A Star Wars Story, which tells the tale summarised in the original Star Wars’ opening crawl. This is the story of how the rebels stole the plans to the original “Death Star” – a space station the size of a small moon with a weapon powerful enough to destroy a planet.
An astronaut aboard the International Space Station photographed a sunset that looks like a vast sheet of flame. With Earth’s surface already in darkness, the setting sun, the cloud masses, and the sideways viewing angle make a powerful image of the kind that astronauts use to commemorate their flights.
Zinnia flowers are starting to grow in the International Space Station's Veggie facility as part of the VEG-01 investigation. Veggie provides lighting and nutrient supply for plants in the form of a low-cost growth chamber and planting "pillows” to provide nutrients for the root system. These plants appear larger than their ground-based counterparts and scientists expect buds to form on the larger plants soon.
Think about underground water and gas as they filter through porous materials like soil and rock beds. On Earth, gravity forces water and gas to separate as they flow through the ground, cleaning the water and storing it in underground pools. Gravity's role is significant in the process, both in nature with ground water and in chemical processes such as water reclamation reactors.
