Summary

The United Arab Emirates Hope spacecraft has begun its journey to Mars. We’ll join a virtual launch party attended by mission leaders, NASA Administrator Jim Bridenstine, National Air and Space Museum director Ellen Stofan and others. Comet NEOWISE is still putting on a show! Learn more about it from NEOWISE principal investigator Amy Mainzer, NASA planetary defense officer Lindley Johnson and JPL scientist Emily Kramer. Our own Casey Dreier provides an overview of three far-sighted white papers submitted as part of the new planetary science decadal survey.

0:00.0	This is planetary radio.
0:03.0	With that lift off from Japan, a new hope began its journey to Mars.
0:18.0	Welcome. I'm at Kaplan of the Planetary Society with more of the successful launch of the United Arab Emirates Mission to the Red Planet with members of the Hope team,
0:36.4	NASA Administrator Bridenstein, George Whitesides of Virgin Galactic, Ellen Stofin of the National
0:42.4	Air and Space Museum, and others.
0:45.0	Then we'll hear from leaders of the mission that discovered Comet Neowise, including
0:49.1	Neowise Principal investigator Amy Meinzer and NASA planetary defense officer Lindley Johnson.
0:55.2	Casey Dreyer also had a big week. The Planetary Society's Senior Space Policy
1:00.9	Advisor submitted three inspiring papers to the National Academy's
1:05.4	Planetary Science Decatal Survey. Casey will be here to tell us about them and
1:10.2	we've got Bruce Batts waiting for us with even more about how to see that comet
1:14.8	and the other wonders lingering above us. Here are just two headlines from the July

1:45.2	eruption or a meteor impact. And by the way, by the time you hear this, it's possible that China's
1:51.3	ambitious Mars Mission, Tianwen 1, may be on its way to
1:55.5	fourth rock.
1:57.3	Speaking to the Moon and Mars, NASA has just relaxed planetary protection requirements for both
2:02.1	bodies. The agency feared the old standards
