Musk says SpaceX will make a formal satellite announcement soon by Ben Geier @FortuneMagazine November 11, 2014, 11:02 AM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons Tesla and SpaceX founder Elon Musk has taken to Twitter to announce out-of-this-world plans for his aerospace company. Last night, Musk tweeter the following about plans for SpaceX: SpaceX is still in the early stages of developing advanced micro-satellites operating in large formations. Announcement in 2 to 3 months. — Elon Musk (@elonmusk) November 11, 2014 The tweet was in response to a story in the Wall Street Journal this weekend reporting that Musk was working with Greg Wyler, a former Google GOOG executive with substantial experience with satellites, on the project. The story said Musk wants to launch 700 satellites weighing less than 250 pounds each, substantially smaller than most communications satellites. Musk doesn’t want anyone to think he is confirming the Journal’s story, though: @RolfeWinkler No, WSJ was wrong on several important points. The article shouldn't have been written on rumor and hearsay. — Elon Musk (@elonmusk) November 11, 2014 This is the second time in the past few weeks Musk has gotten into a Twitter TWTR spat with the Journal. Late last month, he clashed with the paper over reports that Tesla TSLA , his electric car company, was seeing sales decline.
