A: Hey there! Did you know about the space news?
   B: No, I haven't heard anything. What's up?

A: So, Japan's big rocket, the H2A, got delayed from Tuesday! They're rescheduling it for early Sunday morning.
   B: Wow, why did it get postponed?

A: Turns out there was a problem with its electrical systems on the second stage. But they fixed it and checked everything again. It's all good now!
   B: That sounds intense! What's the H2A going to do when it finally launches?

A: It'll carry this cool satellite called GOSAT-GW into space. Its job is to measure greenhouse gas levels in Earth's atmosphere, you know, for climate change stuff.
   B: Oh, that sounds important! How long has the H2A been around?

A: It's been Japan's main rocket for more than 20 years! But after Sunday, it'll be replaced by a new one called H3.
   B: That's sad to see it go, but I guess they need to keep improving technology, right?

A: Absolutely! The H2A has had a pretty good track record – 98% success rate, only one failure back in 2003. Hopefully Sunday's launch will add to that high confidence level!

The operator of Japan&#039;s flagship H2A rocket says the 50th and last launch of the vehicle has been rescheduled for the early hours on Sunday, Japan time.
        
                    
                  
The launch was originally scheduled for Tuesday but postponed due to a malfunction in the rocket&#039;s electrical systems on the second stage.
        
                    
                  
Mitsubishi Heavy Industries said on Tuesday it has completed replacement and re-inspection of a troubled device. The rocket will be launched at 1:33 a.m. from the Tanegashima Space Center in Kagoshima Prefecture, southwestern Japan.
        
                    
                  
The H2A will carry into space a GOSAT-GW satellite, whose mission includes measurement of greenhouse gas levels in the earth&#039;s atmosphere.
        
                    
                  
The rocket has been Japan&#039;s flagship for more than two decades to carry satellites into space. But due to high launch costs and other factors, the model will be completely replaced by the new H3 rocket after its final launch on Sunday.
        
                    
                  
The success rate of H2A&#039;s launch is around 98 percent. The only one that failed was the sixth, which happened in 2003.
        
                    
                  
People are waiting to see whether Sunday&#039;s launch can add to that high confidence level in H2A.
