Maybe even more fun you can watch with Tim Dodd, the Everyday Astronaut, starting at T minus 30! Come ask questions and join the conversation live!

What’s all this mean?

Cygnus is returning to the International Space Station! Very soon, the Antares 230+ rocket will leap off the pad on Wallops Island located in Virginia in the United States. One of the only rockets to launch from there, it will soon be joined by Rocket Lab’s Electron rocket! Our very own Everyday Astronaut had the opportunity to interview the CEO of Rocket Lab Peter Beck… on the launch pad!! See that video here: A conversation with Rocket Lab’s Peter Beck on recovering Electron

Sooo the “230+”… what exactly does that mean? It is essentially just naming the variation of the Antares rocket. Three variations have existed in the history of Antares including the Antares 100 series, the Antares 200 series, and finally the Antares 230+ series. As of now, the 100 and 200 series have been retired. The main difference is in the engine that propels the rocket. The 100 series used two Aerojet Aj26 engines. However, after concerns of wear and tear from aging, the 200 and 200+ series made the big change over to the more powerful modified RD-181 engines. The only difference next would be structural changes when Northrop Grumman switched to the 230 and 230+ series, both of which use the RD-181 engines.

To learn more about rocket engines in general, consider watching Everyday Astronaut’s video about them: Is SpaceX’s Raptor engine the king of rocket engines? 

What about the payload?

The answer to this one is simple. This is a Commercial Resupply Service (CRS) mission which is also performed by SpaceX. Basically, NASA hires various launch providers to safely and quickly get the cargo they need to the ISS. So the Cygnus spacecraft developed by Northrop Grumman, will carry 3,500–3,750 kg (7,720–8,270 pounds) of payload to the ISS. It could include personal items for the astronauts, experiments and special hardware. Not to mention food that is crucial for the astronauts to stay healthy.

    1. The current and updated T-0 is set for February 13th, 2020 – 21:06:05 UTC (12:49:05 PM EST).

  1. Which direction is this launching? For the ISS, it should be northeast or southeast, which would determine whether or not I have any hope of seeing it from the SC area.

  2. I see a mistake on this page, It’s no longer Northrop Grumman Innovation Systems that provides Antares and Cygnus service since that division doesn’t exist anymore since Januari 1st. All space related projects of Northrop Grumman are now reorganized in Northrop Grumman Space Systems.
