The Future of Space Exploration: Space Elevators and Private Funding
TLDR This podcast episode explores the concept of space elevators as a potential alternative method for space travel. Scientists are researching carbon nanotubes to create a strong and efficient space ribbon for the elevator, which could potentially transport large payloads and even humans to space at a more affordable cost. Private funding from billionaires like Jeff Bezos and Elon Musk may play a crucial role in the future of space exploration.
Timestamped Summary
00:00
The podcast episode discusses the topic of space elevators.
03:40
The Space Shuttle Program ended in 2011 after 30 years and 135 missions, and the article discusses the concept of a Space Elevator as an alternative method for getting to space.
07:49
A space elevator is a carbon nanotube composite ribbon anchored to a platform offshore and connected to a counterweight in space, allowing for transportation to outer space.
11:57
Carbon nanotubes, which are incredibly thin but strong, are being used to create a space ribbon for the elevator, but scientists are still trying to figure out how to grow longer nanotubes and understand their properties.
16:04
Scientists are working on bulking up the space ribbon for the elevator and have figured out how to catch and connect the ribbon once it is lowered from space.
19:54
The space elevator would use lasers to power solar panels on the ribbon, which would convert the energy to electricity and allow the elevator to crawl up the ribbon at 118 miles per hour, potentially lifting up to 13 tons of payload at a time, making it a more affordable option for delivering supplies and potentially even humans to space.
23:59
The company LiftPort has put the space-to-earth version of the space elevator on the back burner and is now working on a lunar version, which could be completed within the decade.
27:46
Private space exploration is the future and will likely depend on funding from billionaires like Jeff Bezos and Elon Musk rather than NASA.
