So with a sample of asteroid Bennu firmly inside OSIRIS-REx's return capsule, it's time to bring this treasure home. So scientists can study the composition and history of the space rock. But it's not the only sample return mission out there, with Japan's Hayabusa II mission also bringing asteroid debris home. So today, let's talk about the missions and what we've learned so far.

– Could a terrorist or some other nutcase take over the ISS?

On the whole, terrorists aren't all that bright - though to be fair, that is mostly due to lack of formal education rather than raw brain power.

– OK maybe you can’t physically take over the ISS but what about a cyberattack?

So firstly, I have no expertise in cyber-anything, so feel free to hit the off switch now. If you are still with us, then yes a cyberattack on the ISS is totally possible.

Host: Fraser Cain ( @fcain )
Special Guest: This week we are pleased to welcome Dr. Natalie Cabrol, Director of the Carl Sagan Center for Research at the SETI Institute (SI), to the show.

In addition to heading the strategic vision for science and exploration at the SI, Nathalie leads research projects in planetary science and astrobiology, develops science exploration strategies for Mars, Titan, and the Outer Solar System icy moons, and designs robotic field experiments. She explores high altitude lakes in the Andes where environmental conditions are analogous to early Mars. With her team, she documents life’s adaptation to extreme environments, the effect of rapid climate change on lake ecosystems and habitats, its geobiological signatures, and relevance to planetary exploration, and explores questions relating to the origins and nature of life.

By Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan.

The guys talk about the often overlooked beauty of our nearest cosmic neighbor, the Moon. They discuss unaided, naked eye observing, sketching, the best times to observe, the different areas on the Moon and what sorts of things you can actually see with a telescope or binoculars. They also discuss their favorite sights on the Moon and good books and charts to buy.

Paul Hill, Ralph Wilkins and Jenifer Millard host. Damien Phillips and John Wildridge produce.

As the exciting news of phosphine in the atmosphere of Venus turns into a point of contention in the astronomy world, we caught up with the study’s lead scientist Professor Jane Greaves for the inside track. In this interview we discuss:

• Getting time on a range of professional telescopes time for a risky hypothesis.
• How life could survive in the extreme environment of Venus’ highly acidic atmosphere.
• Floating graphite balloons in Venus’ atmosphere.
• Scientific challenges to this discovery being helpful rather than unwanted.
• Blinding NASA pilots in the name of science.

Today's 2 topics:

- I discovered a 200’ diameter asteroid & a friend asked what it would be like to witness the impact of such an object.

- I discovered a 200 foot diameter asteroid, 2014 SC324. In the case of 2014 SC324 its brightness comes about from the fact that as it passes the Earth opposite to the Sun it appears like a little full moon in the sky.

Music composed by Mark Allnut.

This week on The Cosmic Savannah Podcast we are joined by South African Astronomer, Dr. Tana Joseph who is currently based at the University of Manchester, UK. Tana holds a Royal Society Newton International Fellowship and researches things called X-ray binaries.

X-ray binaries are a type of binary star system that emit X-rays. The X-rays are produced by matter falling from a star onto an exotic object such as a neutron star or black hole.

Tana also runs AstroComms, a Science, Technology, Engineering and Mathematics (STEM) consulting and communications company. AstroComms assists STEM practitioners, institutions and policymakers to effectively leverage STEM as a driver for economic and social development.
