    Episode 628: Q&A 117: Why Am I So Negative About Aliens? And More... Featuring Dr. Jason Wright

    In this week's questions show, I explain why I've got such a skeptical view about the search for aliens if there might be multiple great filters, and why NASA doesn't just go back and use Apollo hardware to return to the Moon?


    Follow Dr. Wright on Twitter:
    https://twitter.com/astro_wright


    00:40 Are there multiple Great Filters?
    02:35 Could we refuel ships in space to land on Mars
    06:01 Could we put a light on the Moon to prove what we landed there?
    08:18 Will James Webb Launch?
    09:52 What will it take to confirm signs of life?
    12:30 How long until cosmic rays die down?
    16:03 Why don't we just use Apollo hardware to go back to the Moon?
    19:46 Why am I so negative?
    22:29 Good sources of journals?
    25:43 When will you believe that it's actually aliens?


    Want to be part of the questions show? Ask a short question on any video on my channel. I gather a bunch up each week and answer them here.

    Episode 627: We've Never Seen the Sun's Poles. That's About to Change With Solar Orbiter

    Episode 627: We've Never Seen the Sun's Poles. That's About to Change With Solar Orbiter

    On February 9, 2020, the European Space Agency’s Solar Orbiter spacecraft launched from Cape Canaveral Florida on top of an Atlas V 411 spacecraft. The spacecraft’s mission is to fly inside the orbit of Mercury, on a tilted orbit that takes it above and below the Sun, capturing images of the Sun’s poles for the first time.


    This is just a year and a half after the launch of NASA’s Parker Solar Probe, which will fly even closer. Together, the two spacecraft will measure the Sun from every angle up close, providing detailed images and insights of our closest star, to help understand how it creates and controls the giant bubble of plasma that surrounds the entire Solar System.

    Episode 626: This is the Highest Resolution Image Ever Taken of the Sun

    Episode 626: This is the Highest Resolution Image Ever Taken of the Sun

    You’re looking at the highest resolution image that has ever been taken of our Sun, using the brand new Daniel K Inouye Solar Telescope in Maui.


    These lighter regions are convection cells, blobs of hot gas the size of Texas which have carried heat from deep below the surface of the Sun, releasing it into space. The darker lines are cooler regions, where the material is sinking back down into Sun.


    This image is just a demonstration of the incredible power of this 4-meter observatory, which will join NASA’s Parker Solar Probe and ESA’s Solar Orbiter in ushering in the golden age of solar astronomy.

    Episode 623: Escape! Spaceflight Abort Systems from the Launch Pad to Interplanetary Travel

    Episode 623: Escape! Spaceflight Abort Systems from the Launch Pad to Interplanetary Travel

    On Sunday, January 19th, 2020, SpaceX launched a Falcon 9 rocket carrying its newly designed Crew Dragon spacecraft. 84 seconds into flight, at the moment of maximum aerodynamic pressure, the capsule fired its eight SuperDraco thrusters, detaching from the top of the rocket and flying ahead.


    Moments after, the Falcon 9 rocket exploded in midair, destroying a completely good rocket, but the capsule was completely safe, jettisoning its trunk and landing gently in the ocean a few minutes later.


    Nobody was on board the spacecraft, just a couple of test dummies, but this test proved that in the case of an emergency during the ascent stage fo the mission, Crew Dragon would be able to carry its astronaut crew to safety.
