Elon Musk’s aerospace business SpaceX has ordered one of the larger advertising packages available from Twitter, the social media business he just acquired in a $44 billion deal and where he is now serving as CEO.

The campaign will promote the SpaceX-owned and -operated satellite internet service called Starlink on Twitter in Spain and Australia, according to internal records from the social media business viewed by CNBC.

The ad campaign SpaceX is buying to promote Starlink is called a Twitter “takeover.” When a company buys one of these packages, they typically spend upwards of $250,0000 to put their brand on top of the main Twitter timeline for a full day, according to one current and one former Twitter employee who asked to remain unnamed because they were not authorized to speak on behalf of the company.

Users should see Starlink brand messaging for the first three times that they open the Twitter app on the day or days of the planned takeover campaign in Australia and in Spain. The campaign, which was purchased in the last week, was slated to run in coming days first in Australia then in Spain.

SpaceX has not typically purchased large advertising packages from Twitter, the current and former employees said.
