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.Continue reading “Time-lapse Captured from the International Space Station”
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.Continue reading “They’ve Got Spacesuits that Fit Now. Christina Koch and Jessica Meir Will Spacewalk on October 21st”
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.Continue reading “Nine Astronauts from Four Different Space Agencies are on the International Space Station Right Now”
We’re accustomed to astronauts pulling off their missions without a hitch. They head up to the International Space Station for months at a time and do what they do, then come home. But upcoming missions to the surface of the Moon, and maybe Mars, present a whole new set of challenges.
One way astronauts are preparing for those challenges is by exploring the extreme environment inside caves.Continue reading “Astronauts Explore Caves on Earth, Learning the Skills They’ll Need for the Moon and Mars”
What sounds like a slap-stick comedy shtick is actually solid science. With so much of humanity’s space-faring future involving habitats, other structures, and a permanent presence on the Moon and Mars, mixing concrete in space is serious business. NASA has a program of study called MICS, (Microgravity Investigation of Cement Solidification) which is examining how we might build habitats or other structures in microgravity.Continue reading “Astronauts Try Mixing Concrete in Space”
One of the obstacles to long space missions is the muscle loss that astronauts suffer from. It’s called atrophy, and NASA says that astronauts can lose up to 20% muscle mass during missions of only 5 to 11 days. This muscle loss affects what are called “anti-gravity muscles,” including calf muscles, the quadriceps and the muscles of the back and neck.
This muscle loss makes it hard for astronauts to complete their tasks, especially when missions to Mars happen. It can also be very dangerous to astronauts, because they’re weakened when they return to Earth. If there are problems during re-entry, and they need to perform any strenuous emergency procedures, that missing muscle could be the difference between life and death.Continue reading “New Ideas to Reduce Muscle Loss During Spaceflight”
One of the most notable features of the modern space age is the way that new participants are entering the fray. In addition to the traditional contenders – NASA and Roscosmos – China has become a major player in space in recent decades. And in 2022, according tor recent statements, India will join the club too when it becomes the fourth nation to send a crewed mission to space.
During a cabinet-level meeting that took place on Friday, Dec. 25th, the government of India announced that the Indian Space Research Organization‘s (ISRO) first crewed mission to space will consist of a three-astronaut team being sent to orbit. The government also announced that they had a approved a budget of $1.4 billion to fund the development of the requisite technology and infrastructure for the program.
The Soyuz MS-10 spacecraft carrying crew to the ISS was aborted shortly after launch on Thursday, Oct. 11th when its booster failed. The spacecraft executed an emergency ballistic landing with a sharp angle of descent. Both crew members on board—American astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin—exited the capsule safely and are in good condition.
The Indian Space Research Organization (ISRO) has made immense progress since the turn of the century. From its humble beginnings, launching satellites into orbit between 1975 and 2000, the ISRO sent their first mission to the Moon in October of 2008 (the Chandrayaan-1 orbiter), followed by their first mission to Mars – the Mars Orbiter Mission (MOM) – in November of 2013.
And in the coming years, the ISRO intends to become the fourth space agency to send astronauts into space. In so doing, they will join an exclusive club of space agencies that consists of only Russia, the United States and China. Last week (on September 7th, 2018) the organization unveiled the spacesuit that their astronauts will be wearing when they make this historic journey.
Even if you know nothing about hurricanes, an unavoidable sense of doom and destruction overtakes you when you look at this image of Hurricane Florence as it moves inexorably toward North and South Carolina.
Even if you didn’t know that the powerful storm is forecast to gain strength as it hits the coast on Friday, or that it will dump several months of rain onto the region in a mere few days, or that the storm surge could reach as high as 9 to 13 ft. If you didn’t know all those things, the picture of Florence taken from space would still fill you with foreboding.
