Giving Mysterious Venus the Love (and Science) She Deserves
3459
We have so much to learn about Venus, says JPL scientist Sue Smrekar.&nbsp; What we learn will help us understand our own world and Mars.&nbsp; Sue joins us this week to make a great case for a new Venus orbiter. The Parker Solar Probe has begun its exciting journey to “touch the Sun.” Our MaryLiz Bender talks with mission leaders before and after the launch. Bruce Betts and Mat Kaplan have two great space trivia contests to wrap up right after they take us on another What’s Up tour of the solar system and back through the history of space exploration.&nbsp; Learn more at:&nbsp; &nbsp;<a href="http://www.planetary.org/multimedia/planetary-radio/show/2018/0815-2018-sue-smrekar-venus-parker-solar-probe-launch.html"><strong>http://www.planetary.org/multimedia/planetary-radio/show/2018/0815-2018-sue-smrekar-venus-parker-solar-probe-launch.html</strong></a><br><br>Learn more about your ad choices.

Dark Energy’s Co-Discoverer and the Leader of Chinese Space Science
2470
It has been 20 years since we learned the expansion of the universe is accelerating due to the mysterious force called dark energy. Saul Perlmutter shared the Nobel Prize in Physics because of his contributions. Now he shares his thoughts with us.&nbsp; Also at this year’s COSPAR Assembly in Pasadena was the Director General of China’s National Space Science Center, Wang Chi.&nbsp; Have you played with Eyes on the Solar System?&nbsp; JPL’s Kevin Hussey conceived of the NASA Eyes app that will take you across the solar system and beyond.&nbsp; And you’ll hear Planetary Society co-founder Carl Sagan’s message to the Martians in our future.&nbsp; That’s right after this week’s What’s Up.&nbsp; Learn more at:&nbsp; &nbsp;<a href="http://www.planetary.org/multimedia/planetary-radio/show/2018/0808-2018-saul-permutter-wang-chi-nssc.html"><strong>http://www.planetary.org/multimedia/planetary-radio/show/2018/0808-2018-saul-permutter-wang-chi-nssc.html</strong></a><br><br>Learn more about your ad choices.

Space Policy Edition: Destination…Mars? Contradictions and Principles
3705
The Senate just held a hearing on NASA's efforts to send humans to...Mars? A week later, the same committee advanced legislation to extend the life of the International Space Station to 2030, six years beyond the current end-date and two years beyond the current hardware safety ratings. Does that extension undermine efforts to get to Mars? What about the Moon? Casey and Jason also introduce The Planetary Society's new principles for human spaceflight, which provide a framework by which the organization will evaluate plans for human exploration.&nbsp; More resources to explore this month’s topics are <a href="http://www.planetary.org/multimedia/planetary-radio/show/2018/space-policy-edition-28.html"><strong>http://www.planetary.org/multimedia/planetary-radio/show/2018/space-policy-edition-28.html</strong></a><br><br>Learn more about your ad choices.
