hey everyone welcome to open space for June 17th 2019 the penultimate episode before we go on to our summer hiatus of live events not all the stuff in fact just the weekly space hangout astronomy cast and open space those are the live events and of course the problem is that every week I have to scramble to make sure that I'm close to high-speed In...

Questions & Answers

Q: Why do rockets launch vertically before turning sideways?

Rockets launch vertically to quickly escape the majority of the Earth's atmosphere and then turn sideways to gain the necessary orbital velocity.

Q: How much does a good telescope cost?

A recommended telescope for beginners, like the Dobsonian telescope, can be purchased for around $300-$500.

Q: What is LIGO currently detecting?

LIGO is detecting one new gravitational wave event, such as black hole collisions or neutron star collisions, every week.

Q: Could humans visit Jupiter's moons despite the strong radiation belt?

It would be challenging for humans to visit Jupiter's moons due to the intense radiation belt surrounding Jupiter, which poses significant risks to human health.

Q: What is the purpose of the Lunar Gateway?

The Lunar Gateway is a planned space station that will serve as a stepping stone for future manned missions to the moon and other destinations.

Q: Are there any viable proposed methods for drilling through Europa's ice?

Scientists have proposed using induction heating or other methods to drill through Europa's miles-thick ice, but research is still ongoing.

Q: What are the potential risks of asteroid mining?

The potential risks of asteroid mining are primarily ethical in nature, such as the destruction of celestial bodies and the potential impact on extraterrestrial life.

Q: What are the implications of AI ethics?

AI ethics are crucial to ensuring that the development and deployment of artificial intelligence technology are done responsibly and safely, as there are potential risks and ethical concerns associated with AI.
