There are a number of health risks that come with going to space. Aside from the increased exposure to solar radiation and cosmic rays, there are the notable effects that microgravity can have on human physiology. As Scott Kelly can attest, these go beyond muscle and bone degeneration and include diminished organ function, eyesight, and even changes at the genetic level.

Interestingly enough, there are also a number of potential medical benefits to microgravity. Since 2014, Dr. Joshua Choi, a senior lecturer in biomedical engineering at the University of Technology Sydney, has been investigating how microgravity affects medicine and cells in the human body. Early next year, he and his research team will be traveling to the ISS to test a new method for treating cancer that relies on microgravity.

Boeing and Airstream Show off Their New Astronaut Transport Vehicle: the Astrovan II

Airstream's Astrovan II will transport astronauts to the launchpad for commercial crew launches aboard Boeing's CST-100 Starliner spacecraft. Astrovan 2 is the successor to the original Astrovan that carried Shuttle astronauts. Credit: Airstream

When it comes to brand recognition, Airstream‘s got game. Their silver, space-age looking travel trailers and touring coaches are iconic. Almost everyone recognizes their riveted aluminum bodies.

400 photos. 11 minutes. That’s what it took to create this time-lapse of the Earth and stars as the International Space Station over Namibia toward the Red Sea. NASA astronaut Christina Koch captured these images.

They’ve Got Spacesuits that Fit Now. Christina Koch and Jessica Meir Will Spacewalk on October 21st

The all-female astronaut walk is back on.

Back on March 26th, 2019, NASA was forced to cancel the first all-female spacewalk because they didn’t have the right spacesuits available on the ISS. There was a short-lived social media storm over that development, as some claimed it was evidence of sexism on the part of NASA. But that small storm didn’t have legs and it died out, because no serious-minded observer thinks that NASA is actually sexist.

Now, the problem has been worked out, and the spacewalk will happen on October 21st, when astronauts Christina Koch and Jessica Meir will walk outside the ISS and install new lithium-ion batteries. Theirs is the first of five walks needed to complete the installation.

Nine Astronauts from Four Different Space Agencies are on the International Space Station Right Now

The International Space Station’s usual complement of six astronauts grew by 50% recently, making things a little crowded up there. The nine astronauts come from four separate space agencies, and for the first time, an astronaut from the United Arab Emirates (UAE) is onboard the ISS.

The ISS is a multicultural place. Astronauts from around the world serve on the station to advance the scientific goals of humanity and to build cooperative ties between Earth’s different peoples. It’s kind of like Star Trek, but in space.

Mice That Spend a Month in Space Were Able to Reproduce Once They Got Back to Earth

A team of Japanese researchers have used sperm from mice that spent time aboard the International Space Station (ISS) to fertilize female mice back on Earth. While previous research has shown that freeze-dried mouse sperm stored in space can experience radiation damage, these results show that the sperm from live mice may not suffer the same damage.

Upgraded ISS Now Has a 600 Megabit per Second Internet Connection

In the digital age, connectivity and bandwidth are important, even if you’re in Low Earth Orbit (LEO). And when you’re performing research and experiments that could help pave the way for future missions to the Moon, to Mars, and other deep-space destinations, it’s especially important. Hence why NASA recently upgraded the ISS’ connection, effectively doubling the rate at which it can send and receive data.

Astronauts Could Rely on Algae as the Perfect Life Support Partner

From the Soyuz capsule, Space Shuttle Endeavour during Expedition 27 is docked to the International Space Station 220 miles above the Earth. Before Apollo 11 landed on the Moon, plans were underway to develop the next generation spacecraft that would lower the cost of human spaceflight and make trips routine. Forty years have passed since the Saturn rocket last flew and four years since the last Shuttle. Supporters on Capital Hill appear resigned to accept a replacement for the Shuttle, while inhernently safer, will cost $600 million per launch excluding the cost of the payload. SLS is destined to server both humand spaceflight and robotic missions. (Photo Credit: NASA)

When planning for long-duration crewed missions, one of the most important things is to make sure that the crews have enough of the bare essentials to last. This is no easy task, since a crewed spacecraft will be a crew’s entire world for months on end. That means that a sufficient amount of food, water and oxygen will need to be brought along.

According to a new investigation being conducted aboard the International Space Station, a possible solution could lie with a hybrid life support system (LSS). In such a system, which could be used aboard spacecraft and space stations in the near future, microalgae would be used to clean the air and water, and possibly even manufacture food for the crew.

X-rays Might be a Better Way to Communicate in Space

In the coming years, thousands of satellites, several next-generation space telescopes and even a few space habitats are expected to be launched into orbit. Beyond Earth, multiple missions are planned to be sent to the lunar surface, to Mars, and beyond. As humanity’s presence in space increases, the volume of data that is regularly being back sent to Earth is reaching the limits of what radio communications can handle.

For this reason, NASA and other space agencies are looking for new methods for sending information back and forth across space. Already, optical communications (which rely on lasers to encode and transmit information) are being developed, but other more radical concepts are also being investigating. These include X-ray communications, which NASA is gearing up to test in space using their XCOM technology demonstrator.
