I'm changing things up for my prediction posts. For this year, I'm going to lay out a random number of different predictions for almost every nation's space program and their subsections. Here we go.
SPACEX27 Falcon 9 rockets are flown; 10 of which are Starlink missions.
3 Falcon Heavy rockets will be flown; AFSPC-52 will be one of the FH missions. Also, on the very next FH mission (#4), the center core will FINALLY be recovered safely without tipping over.
The Inflight Abort Test mission is a complete success with all the tracking cameras capturing every moment of the abort.
The DM-2 mission with Behnken and Hurley is extended to six months and the astronauts are launched to the ISS somewhere between March and April.
At least two atmospheric tests of Starship Mk.1 are conducted before Mk.2 does the last test of the year.
NASANASA begins to reconsider the status of Artemis and mulls over the possibility of relying solely on SpaceX's SH/SS stack for interplanetary missions, realizing that the billions of dollars spent on the Space Shuttle hardware composing of Artemis are a waste.
The Mars 2020 rover is launched on time towards the Red Planet (July 17), but the RD-180 shuts down one second early, forcing the Centaur to burn longer; however, the planned speed is achieved and the launch is constituted as a success.
After seeing Boeing and SpaceX conduct their Orbital and Crewed Flight Tests, NASA declares that they will NOT buy more Soyuz seats as they feel confident about the Crew Dragon and Starliner.
ULA10 missions are flown within 2020; two of them are Delta IV Heavys.
The SMART package concept is dropped, having seen Rocket Lab and SpaceX recover first stage boosters in their entirety (I mean, why only recover the engines?).
With extra performance available on the maiden Vulcan flight, which is launching the Peregrine lander, ULA decides to use a Cygnus spacecraft as a primary payload (as seen on an earlier launch profile video; except it was showing an Atlas V).
ARIANESPACEDevelopment of the Ariane 6 continues as planned.
Twelve missions will be flown; two are Vega-C, three are Vega, three are Soyuz, and the remaining four are Ariane 5. All are successful with no failures at all.
ISROEleven missions are flown; seven are PSLV, two are GSLV Mk.2, and the remaining two are GSLV Mk.3. Only one PSLV is a partial failure.
ISRO announces the first astronauts to be flown on their Gaganyaan spacecraft.
ROCKET LABTwenty missions are flown successfully; eight of them fly from Wallops Island, and two of them involve the first stage boosters being recovered.
BOEINGThe Orbital Flight Test is a success with the parachute sequence during landing performing as planned (all three chutes deploying).
The Crewed Flight Test is also successful with Mike Fincke commanding the next ISS expedition after three of the Soyuz members leave.
BLUE ORIGINTwo New Shepard missions are flown with tourists onboard. On the second flight, one of the tourists vomits all over the place due to motion sickness.

More details on New Armstrong are announced.
The first New Glenn is launched somewhere between November and December; the first stage booster fails to stick the landing.
RUSSIAFour crewed ISS missions are flown using the new Soyuz-2 rocket.
Two Angara 5 missions and two Angara 1.2 rockets are launched. All of them are launched in secrecy; no live coverage.
CHINAThree Long March 5s are launched successfully; one of them carries Chang'e 5 to the Moon.
Shenzhou 12 is launched somewhere in the second quarter.
Two ESA astronauts are selected to each fly on subsequent Shenzhou missions.
