As the International Space Station nears the end of its life, SpaceX and Los Angeles-based startup Vast have unveiled a plan to launch the first commercial space station.
SpaceX will use a Falcon 9 rocket to send the station’s main module, Haven-1, into low-Earth orbit as early as August 2025.
You may not have heard of piezoelectric materials, but odds are, you have benefitted from them.
Piezoelectric materials are solid materials —like crystals, bone or proteins—that produce an electric current when they are placed under mechanical stress.
Materials that harvest energy from their surroundings (through light, heat and motion) are finding their way into solar cells, wearable and implantable electronics and even onto spacecraft. They let us keep devices charged for longer, maybe even forever, without the need to connect them to a power supply.
Four crewmembers at the International Space Station (ISS) enjoyed a short ride aboard SpaceX’s Crew Dragon Endeavour on Saturday, moving the spacecraft to a different port to make way for a cargo ship arriving in June.
SpaceX Crew-6 members Stephen Bowen and Woody Hoburg of NASA, along with Sultan Alneyadi of the United Arab Emirates and Andrey Fedyaev of Russia, undocked from the Harmony module’s space-facing port at 7:23 a.m. before flying the short distance to the same module’s forward port.
Will it ever be possible for us, humans, to travel to another star system? This video was inspired by a debate that took place on an article I wrote on that same topic.
Some peole argue the distance is just to far, therefore it will be imossible.
I this video I list some near-future technologies, something we can build within the next 200 years gven what we know today, and reach another star system.
The International Space Station (ISS) is nearing the end of its service. While NASA and its partners have committed to keeping it in operation until 2030, plans are already in place for successor space stations that will carry on the ISS’ legacy.
One of the most critical problems for space travel is the enormous distances at which objects are found. In the solar system alone, the planets are so far away that going from one to another would take several years or even decades while going to the closest stars would take centuries or thousands of years. A human being cannot carry out such a long journey since we do not live that long, so a possible solution to this problem is cryogenic sleep or induced hibernation. This is a method in which we could put astronauts into an artificial coma, putting them in capsules or chambers where they would remain asleep for decades or even centuries and then wake up until they reached their destination. How possible is it to do this for modern science? Is there cryogenic sleep for space travel? Let’s find out!
Cryogenic sleep. Cryogenic sleep can be considered a kind of artificially induced human hibernation. Various animals can lower their metabolism in nature by lowering their body temperature. In this state of biostasis, they can spend months on limited food and water.
Examples of cryogenic preservation. Although it sounds hard to believe, some companies are dedicated to preserving frozen human bodies to revive them in the future.
Advantages and disadvantages. Let’s start with the advantages; first of all, astronauts could travel for months or years without feeling the passage of time in their bodies. Mental health is problematic when you spend so much time coping with other individuals in a confined space.
