List of Space Launch System launches

[17][18][19] SLS was considered as a potential launch vehicle for the proposed Large UV Optical Infrared Surveyor (LUVOIR) space telescope, which will have a main segmented mirror between 8 and 16 meters in diameter,[20] making it 300 times more powerful than Hubble Space Telescope.

[25] The joint NASA-ESA Titan Saturn System Mission proposal envisioned the SLS as an option for launch.

[27] In July 2021, NASA booked a SpaceX Falcon Heavy launch for Europa Clipper at a price of $178 million.

[28] In addition to being much cheaper to launch, the Europa Clipper spacecraft would not need expensive structural modification to handle vibrational loads caused by the SLS's solid rocket boosters.

The total cost savings was estimated at US$2 billion, but Europa Clipper will need three years longer to reach Jupiter on account of the smaller Falcon Heavy launcher.
