Usually Wednesdays are for Rocket Roundup, and today is going to be a little different.  Rather than cover all of the launches that occurred in these past few weeks, I’m going to do a quick round up of the past year in spaceflight.

There were 97 successful rocket launches out of 102 total launches, which gives us a success rate of 95% — not perfect, but not too shabby either!

So, who won the Space Race in 2019?  If you guessed China, you’d be correct.  According to Gunter Krebs’ careful tally, China has launched 34 rockets.  Space enthusiasts on Wikipedia agree with this number. (And yes, I know, I shouldn’t use Wikipedia as a first source but there’s just so much to keep track of!)

Now, depending on how you tally up launches, who comes in second and third can vary.

If you go by spaceport, China is still in the lead.  Russia comes in second place with 22 launches, followed by the US with 21 launches.

But wait!!  If you tally everything up by the rocket’s country of origin, the numbers change!  RocketLab’s Electron rockets are manufactured in the US, so those 6 rocket launches get added to update America’s total to 27 and boost them to second place.  And those Soyuz rockets that Arianespace launches from Kourou? Those are manufactured in Russia, so Russia’s tally gets a small boost to 25.

Now, for the largest and smallest rockets of 2019! Weighing in at a massive 1,420,788 kg, SpaceX’s Falcon Heavy was the heaviest rocket launched last  year. To put that number in perspective a bit, that’s 237 male African elephants.

The smallest orbital rocket launched last year was RocketLab’s Electron with a mass of 13,000 kg.  In case you’re curious, that’s just over the combined mass of 2 male African elephants.

If you were to put the two rockets side by side, the Electron would be dwarfed by the Falcon Heavy. The Electron is 17 meters tall which makes it not quite a fourth of the height of the 70 meter tall Falcon Heavy.

There were three lunar attempts last year, one each by China, India, and SpaceIL.  Unfortunately, only the Chinese lander had a successful soft landing. SpaceIL’s Beresheet and India’s Vikraam lander both crashed into the lunar surface.

It’s not bad: Chandrayaan-2 continues to orbit the Moon, collecting data for India’s space program.

And the Chang’e lander and rover Yutu-2 are doing science of their own.  The Chinese lander took the first panorama from the far side of the moon after it touched down last year. 

Speaking of rovers, there were two wheeled rovers exploring other worlds last year: NASA’s Curiosity and China’s Yutu-2. Together, they covered just over 2 kilometers of alien terrain.  Curiosity traveled 1.71 kilometers on Mars and Yutu-2 traveled a bit more than 357 meters during its year on the lunar surface.

Even though it hasn’t covered a lot of ground, Yutu-2 belongs in the “little rover that could” club.  It is now the longest-lived lunar rover with a mission duration of over a year. Previously, the Russian Lunokhod 1 rover held the record at 321 days of operation on the lunar surface.

And finally, a moment to recognize some of the spacecraft missions that ended this year.

In no particular order:
