NASA’s Osiris-Rex arrives at potentially Earth-bound asteroid Bennu
The article linked above from Dec '18 is over-stuffed with nuggets. It has it all, big numbers, a threat, a plot, school boy humour, etc. I'd say read it first, it's not too long, then come back for the comic dissection of the main bits. I'll wait, it's comedy gold in its own right.

Tldr:
So, we've sent the Osiris-Rex probe to asteroid Bennu, a 2-year 2 billion kilometer journey, where it is now in a tightening corkscrew orbit for 2 years, until it is close enough to high five the asteroid with gas, so it can waft a collection chamber to catch the dust, before returning back to earth with the sample." Got it it? Good.
Of course, the real story was that Benny had spent too many nights at the bar, his deadline was looming, and he had to get something out, and quick! Grabbing whatever came to hand - a newspaper with crossword clues, he scanned this for interesting words and cooked up this sorry saga in just a couple of hours. Eat your heart out JK Rowling!

The title:
- Osiris-rex - conspiracy fusion cuisine (Egypt+dinosaur refs)
- Potentially earthbound - unlike the 'astronauts' who dreamed this up whose brains are definitely spacebound.
- Bennu - (serious, sort of) maybe the author of this tale was called Benny?

- artist rendering - honest at least!
- product placement, though the product sounds a bit icky.
Main content
- "two-year, two-billion-kilometer journey" 22 then, not a 3 year 3 billion km journey for 33..
- "the Osiris-Rex craft’s odometer" - space probes have odometers too dontcha know!
- more tech stats - "It completed the journey with a 20-second thruster burn to arrive within 12 miles (19km) of the 1,600ft (500-meter) diameter, diamond-shaped space rock."
- excitement at mission control - "My heart-rate is three times faster than normal but I’m super-excited."
- gah! complicated terms - "One of the primary objectives of @OSIRISREx is to understand the Yarkovsky Effect - a non-gravitational force that can change an asteroid's orbit." Brain hurts. But luckily there's a kids picture of an asteroid about to hit a dino. Even I get that!
- cost is $800 million
- it could hit in.... September 2135. I'm worried! That's according to Lindley Johnson, a planetary defense officer with Nasa’s Science Mission Directorate. Better than my title!
- the fantasy and numbers continue: "There is reportedly a one-in-2,700 chance of Bennu striking the Earth in 166 years, placing Bennu at number two in NASA's rankings of 72 potentially hazardous Near-Earth Objects (NEOs)." 27 then 72? 166?
- the mission? To bring back a sample - "to bring back between 60 grams (two ounces) and two kilograms of regolith (dust and gravel from the asteroid’s topsoil), the most extraterrestrial material retrieved since the Apollo mission landed on the moon". 6 and 2 again. Collecting regolith, eh? Regolith. That must be a band name.
- but how? "the craft will establish a gradually tighter orbit by spiralling down to a distance of roughly six feet for its retrieval mission sometime in July 2020. The probe will extend its three-meter robotic arm to give the asteroid a ‘high five,’ blasting it with pressurized gas to kick up scree which will then be collected in a sterile holding chamber". Parp!! Oh, pardon me! That's a low blow though. The probe literally passes gas on Bennu. Numbers 6 and 2 again, btw.
