Falcon Heavy woooooo! We spent most of the recording running around cheering, but eventually we settled down and also talked about a very fast Progress, a scuttled F9 booster and JWST's optics package.

This week, we had to say goodbye to one of the most experienced astronauts. Godspeed, John!

Falcon Heavy shows continued signs of actually flying sooner than six months in the future, Angosat-1 had a hiccup and Blue Origin buys land.

Students for the Exploration and Development of Space has a chapter at University of Central Florida, and they've entered the Intercollegiate Rocket Engineering Competition. They had a successful failure last year, and now they're here to talk about their run up for next year.

3D printed rockets, cubesat toys and commercial lunar landings.

A Frigat-M went Full Kerbal, Elon Musk promises to go Full Kerbal in the future, Voyager is being clever with engine degradation and SLC-40 is good to go!

We found out more info about Dream Chaser's drop test, and we discuss a new space nuclear reactor

We now know what Zuma probably looks like, but who the heck is operating it? Also, some info on New Glenn and LauncherOne.

We blew up a Merlin and dropped a Dream Chaser.

Laura Forczyk studies the space industry professionally, and we get to talk to her about what services she provides as well as some of her predictions!

Will we see the race for space internet begin in the next few months?

Zach and Kelly Weinersmith just published a book called Soonish, a humorous-but-factual look at 10 upcoming technologies. Since a few are in space, we thought we'd talk to Zach about the book!

VRSS-2 was recently launched on a Long March. While it's a fairly conventional Earth observation satellite, we got ahold of its system designer to talk about what makes it different and what the challenges were in building it.

Dr. Bennett is the Spitzer Science Center Deputy Manager, and we got to talk to him about the space telescope's history and operations.

This week we mostly talk about Elon Musk's IAC presentation.

Tianzhou 1 is done, and so is Orbital ATK.

NASA outlines an exciting, laser-focused Mars sample return mission, and SpaceX released another photo of their flight suit.

We discuss the recent loss of IRNSS 1H, trapped in its fairing, and we learn about a newly discovered flaw in Intelsat-33e's stationkeeping thrusters. Also we get a little more clarification on the Dragonrider suit.

Let's go shopping for pressure suits. Also, ISS gets CREAMy, and Orion and Orbital ATK both get fire-y!

Nuclear propulsion, a promise of new space suits, TDRS-M is healthy, the X-Prize will never be won, and another launchpad at KSC.

We learn more about the Rocket Lab's first flight failure, a minimalistic cubsat failure , and an H-IIA that was grounded (due to a failure).

Jason Seagram works at CSA, and was a major part of the recent MBSU RnR.

There are two MPLMs in storage right now... and one of them might be headed to the moon! Also, another short-sighted US space telescope.

Accion Systems is an MIT spin-off that's developing a new type of electric propulsion, and a very promising one! Also, we heard a bit of Mars news from Elon Musk.

TDRS-M got a little banged up during encapsulation, and Moon Express shows off a mockup! Also, lots of questions, comments and correction burns; let's all get smarter!

XCOR is no mor, F9 overperformed, Chinasat made up for an underperformance.

Kam Bahrami sits at the ROBO desk at ISS MCC. We have a quick discussion with him about robotics on Station and the Roll-out Solar Array experiment in particular.

ESA gears up for Prometheus and SpaceX busies itself getting payloads into space.

Orion gets an abort motor test, ROSA gets a deployment test and Pirs stays put.

Sharad Bhaskaran is Astrobotic's Mission Director, which means he's going to be responsible for sending payloads to the surface of the Moon. Also: lots of SpaceX speculation and two fantastic correction burns, one from Ben Honey of Johnson Space Center!

An unexpected ISS departure, the Space Foursquare Ball is halfway to the finish line, Stratolaunch stretches its legs, and SpaceX has a ticket price in mind for Red Dragon.

Successful failures all around! BE-4 has an explosion, Rocketlab reaches space, Schiaparelli gets investigated and LRO gets tapped on the shoulder.

Since nothing much happened in the news this week, we decided to take a break and instead bring you an episode from a new podcast, hosted by Ben Etherington and Chris Radcliff. Find more episodes at Notion.farm.

Both NASA and Masten damaged some very expensive equipment this week.

Ben talks for too long about his trip to JPL. Vector flies a rocket, ARCA shows off a a crazy rocket, NASA wants cubesats with lasers IN SPACE, and X-37B ends its streak.

Scott Wray trains astronauts and flight controllers to perform and support EVAs. Yes, that's pretty much as cool as you can get. Also, JWST, a handful of short-and-sweet news items and a double handful of comments and corrections!

It's a short show this week. We talk about a Linux nerd in space, China's new cargo vehicle, and some tidbits from a listener going through our archives.
