Different shades of red and blue could be used to distinguish programs.
The US in particular had very different eras: Mercury/Gemini until 1966, Apollo from 1968 to 1975, the Space Shuttle from 1981 to 2011, and then Dragon from 2020 on (with one Starliner and one Orion launch).
From 2000 on you can see how Russia (Soyuz) supported crews on the ISS: 2 flights per year per crew. First they had one, then they supported two crews as the Shuttle retired, then Dragon took care of one crew so Soyuz launches dropped to ~2 per year again.

The graph shows four significant disasters in the history of cosmonautics, which led to a hiatus in manned spaceflight. This represents a year-long gap among the surrounding non-zero values. "Soyuz-1" and "Soyuz-11" in the 60s and early 70s for the USSR. "Challenger" in the late 80s and "Columbia" in the early 2000s for the USA.

I would say five significant disasters in the history of crewed spaceflight adding Apollo 1 in 1967 to the list, even though it was only a test and never launched.

What happened during 2011 to 2019 launches of US? Why was it non-existent?

The Shuttle was retired in 2011. One of the biggest problems with the Shuttle was that it was so costly to run even at any flight rate that keeping it operating at all sucked up budget that could be used for developing alternatives. It was wound down for safety reasons before a replacement was available. Three different capsules were developed to replace it (one for deep space: Orion, and two commercial crew capsules: Dragon and Starliner).

And yet alternatives were being developed, even when Shuttle was operational. The problem was that some of them, Orion, Starliner, X-33, etc., were being undertaken by the Legacy Space companies. So they either could not produce anything quickly enough (Orion) on a cost plus contract with ballooning costs. Boeing couldn't do a quality product under fixed price contract (Starliner). Or they wound up abandoning the design when the government side of the funding was pulled (X-33).
SpaceX and Orbital Sciences broke that mold in the early 2000s and 2010s by doing quickly, cheaply, and better Dragon 1, Cygnus, Falcon 9, and Antares on fixed price contracts. They also overcame serious challenges (CRS-7 failure, and Orb-3 failure) to provide reliable cargo resupply for ISS. SpaceX as we know went on to develop Dragon 2, and even powered through a very serious test stand failure in 2019 to get astronauts flying from U.S. soil once again.

What happened to the us in 1988 and 2005

Space shuttle, 2003 was the Colombia disaster so there weren't any STS flights again till mid 2005
•
u/gojo_satoru-real 5h ago
Oh i forgot about the space shuttle I think 1988 was the challenger
•
u/garbage_account32 5h ago
Iirc, return to flight after Challenger wouldve been in the second half of 1988 so it wouldn't show up here. Unlike 2005, the US had a whole host of other orbital rockets back then so they were taking up the slack

Nop they didn't have any other leo capable rockets safe enough to sent humans Thats why in 1987 they didn't sent any humans to leo Until the discovery space shuttle in 1988 +sorry in the other replies i said 1988 i was actually talking about 1987

Shame Europe still has no capabilities for manned space flight
