The International Space Station (ISS) is not only the largest and most sophisticated orbiting research facility ever built, it is arguably the most important research facility we have. With its cutting-edge facilities and microgravity environment, the ISS is able to conduct lucrative experiments that are leading to advances in astrobiology, astronomy, medicine, biology, space weather and meteorology, and materials science.
Unfortunately, the cost of transporting experiments to and from the ISS is rather expensive and something only a handful of space agencies are currently able to do. To address this, the Japanese Aerospace Exploration Agency (JAXA) and Tiger Corporation partnered in 2018 to create a new type of container that would cut the cost of returning samples to Earth. With the success of their initial design, JAXA and Tiger are looking to create a reusable version that will allow for regular sample returns from the ISS.

Early on Thursday, a Long March 5B rocket – currently the most powerful of China’s space launch vehicles – blasted off from Wenchang, carrying the first major component of an ambitious new modular space station.
The station module, dubbed Tianhe (Harmony of the Heavens), marks the next big step in China’s human spaceflight program in Low Earth Orbit (LEO). Barred from participating in the International Space Station (ISS) by US law, which forbids cooperation in space between the two countries, China has been developing its own LEO capabilities for over a decade now.

There are many paths to the Moon, and not all of them go through the Lunar Gateway. This week, the heads of the Russian Space Agency (Roscosmos) and the China National Space Administration (CNSA) signed an agreement to cooperate on a Lunar research station of their own.

Radishes are a very divisive food – most people either love them or hate them. However, they are very easy to grow, and have now been grown in one of the most inhospitable environments of all – the International Space Station.

It’s not easy living and working in space for extended periods of time. As NASA’s Twins Study illustrated, microgravity takes a toll on human physiology, which is followed by a painful transition back to normal gravity (just ask Scott Kelly!) Aside from muscle and bone degeneration, there’s diminished organ function, effects on cardiovascular health, the central nervous system, and “subtle changes” on the genetic level.
Until now, the biggest unanswered question was what the underlying cause of these physical impacts was. But after reviewing all of the data accumulated from decades of research aboard the International Space Station (ISS) – which included the Twins Study and DNA samples taken from dozens of astronauts – an international team of researchers came to the conclusion that mitochondria might be the driving force for these changes.

In this decade and the next, humanity is poised to go to space like never before. National space agencies will be sending astronauts back to the Moon for the first time since the Apollo Era, private launch services will spearhead the commercialization of Low Earth Orbit (LEO), missions to the outer Solar System will search for evidence of extraterrestrial life, and crewed missions to Mars are on the horizon.
In preparation for this, a considerable amount of research is being done aboard the International Space Station (ISS) to determine how extended periods of time in space can affect living beings on the genetic level. In a recent experiment, a team of researchers from the University of Exeter conducted an analysis of worms on the ISS and noted “subtle changes” in their genetic makeup.

One of the biggest threats to the International Space Station (ISS) comes from micrometeoroid impacts. A small hole in the wrong place can throw the resident astronauts into a life threatening situation. Currently, there is no active program to monitor these types of impacts, though scientists think they must be common given the ubiquity of small objects in the ISS’s orbit. An interdisciplinary team from MIT hopes to provide some data to support that theory by using an extremely unusual impact sensor made almost entirely out of fabric.

Earlier this evening (Sunday, November 15th, 2020), NASA and SpaceX achieved another historical milestone. Six months after successfully sending astronauts Robert Behnken and Douglas Hurley to the ISS with the Demo-2 mission, the US demonstrated the restoration of domestic launch capability by sending the fully-crewed Crew Dragon spacecraft (Resilience) on an operational mission to the ISS.

On the evening of Wednesday, Oct. 21st, the crew of Expedition 63 finally returned to Earth after spending 196 days in space. It all began when NASA astronaut Chris Cassidy (commander) and Russian cosmonauts Ivan Vagner and Anatoly Ivanishin (both flight engineers) departed the International Space Station (ISS) aboard their Soyuz spacecraft at 07:32 PM EDT (04:32 PM PDT) and landed in Kazakhstan by 10:54 PM EDT (07:54 PM PDT).

When human beings start living in space for extended periods of time they will need to be as self-sufficient as possible. The same holds true for settlements built on the Moon, on Mars, and other bodies in the Solar System. To avoid being entirely dependent on resupply missions from Earth (which is costly and time-consuming) the inhabitants will need to harvest resources locally – aka. In-Situ Resource Utilization (ISRU).
This means they’ll have to procure their own sources of water, building materials, and grow their own food. While the ISS has allowed for all kinds of experiments involving hydroponics in space, little has been done to see how soil fares in microgravity (or lower gravity). To address this, Morgan Irons – Chief Science Officer of the Virginia-based startup Deep Space Ecology (DSE) – recently sent her Soil Health in Space experiment to the ISS.
