How much payload — the satellites and cargo rockets carry, not the rockets themselves — has reached orbit so far this year, measured in tonnes.
Mass to orbit by launch provider (the company or agency that flew the rocket).
Mass to orbit by launch vehicle type.
“Mass” here means payload mass — the satellites and cargo a rocket carries, not the rocket itself. A Starlink stack, a crew capsule, a science probe: their weight adds up on this page; the rocket's own structure, propellant, and spent upper stages do not.
It's the total payload mass delivered to orbit by successful launches since January 1, measured in tonnes (t). Figures come from Jonathan McDowell's GCAT, which records a payload mass for each launch; failed and suborbital flights are excluded.
Mass to orbit and Launches YTD look related but answer different questions — one weighs each launch by payload mass, the other counts launches equally. A single heavy lift can swing this page's number without moving the launch count at all.
See When two metrics disagree on the methodology page for the full reconciliation.
Sum of payload mass on successful orbital launches since January 1 of the current year.
Jonathan McDowell’s GCAT (launch.tsv)
Launches with LaunchCode = OS (Orbital Success) and a recorded payload mass
Failed launches, suborbital, missile/sounding rockets, deep-space missions
GCAT is maintained by hand and typically lags 1–2 weeks on the most recent launches. Some launches list partial-payload mass.
