For the low, low price of $2.25 million, SpaceX will put your small satellite on a big Falcon 9 rocket and shoot it to orbit with a bunch of similarly small satellites. It's part of a new initiative called the SmallSat Rideshare Program, and with a first flight in late 2020 or early 2021, it will carry only diminutive instruments, a boon for their makers. While a Falcon 9 carried out a similar rideshare mission last year, that launch was organized by another company. This time, SpaceX itself is promising "regularly scheduled, dedicated Falcon 9 rideshare missions," according to its website.

Typically, small satellites have to squeeze in, Tetris-style, alongside larger, more expensive satellites that dictate when the launch happens and what orbit the payload goes to. Smallsat operators never liked that scenario. If the big guy was late, for instance, the little guys had to wait. If the big guy wanted to go to a different orbit than the small satellites, too bad, so sad.
