SpaceX is launching more satellites into space to provide internet service. A Falcon 9 rocket lifted off from Cape Canaveral in Florida this morning at 5:45 PST. This added 48 new satellites to the 2,000-strong constellation of SpaceX’s internet-providing devices orbiting Earth.

This was the fourth launch of the booster, which landed on a drone ship in the Atlantic Ocean a few minutes into the mission.

This SpaceX flight was not new. The company had sent up seven missions this year using the same technology. But there was something interesting about this launch. The person in charge of the mission said something funny before it started.

SpaceX’s launch director called out “time to let the American broomstick fly and hear the sounds of freedom.” She then gave the “go” for launch.

Dmitry Rogozin, the head of Russian space agency Roscosmos, said last week that the United States can “fly on something else” instead of Russian rocket engines. He was referring to a jab made by Rogozin about how the United States can use “broomsticks” since Russia is no longer going to sell them rocket engines.

Falcon 9 rockets use SpaceX’s Merlin engines for propulsion. However, United Launch Alliance’s Atlas V and Northrop Grumman’s Antares rockets use Russian engines. ULA has said that it has enough engines in stock for upcoming launches, but Northrop Grumman has not said anything about how the embargo might affect its missions.

SpaceX is the company that launches most of the rockets in the United States. Today’s launch showed us that their broomsticks are doing just fine.

SpaceX will be launching a new mission on March 30. Unlike their other missions, this one will send a crewed spacecraft to the International Space Station. This will be the first time a spacecraft is sent to the ISS by a private company. SpaceX has plenty of experience with crewed missions – they have already flown 4 NASA crews and 1 all-civilian crew to the ISS.
