Last year, SpaceX announced a bold plan to launch its Dragon spacecraft to Mars as soon as 2018 — in what would be the first ever private mission to the Red Planet, according to The Verge.

But now it looks like the company is pushing back the mission by a couple years. SpaceX president Gwynne Shotwell confirmed today that SpaceX is now targeting the year 2020 for the Mars trip, a move that will allow the company to better focus on its other ambitious projects.

“We were focused on 2018, but we felt like we needed to put more resources and focus more heavily on our crew program and our Falcon Heavy program,” Shotwell said at a pre-launch press conference in Cape Canaveral, Florida. “So we’re looking more for the 2020 timeframe for that.”
