NASA's latest planet hunting satellite TESS (Transiting Exoplanet Survey Satellite) was scheduled to be launched into space by SpaceX this evening at 22:32 UTC, Monday 16 April.

But the team has just announced that the launch has been scrubbed.

They're now working towards a launch window the evening of Wednesday, 18 April.

"Standing down today to conduct additional GNC analysis, and teams are now working towards a targeted launch of @NASA_TESS on Wednesday, April 18," SpaceX wrote on Twitter this afternoon.

GNC is the guidance navigation control on board the Falcon 9 rocket, which was scheduled to put TESS into orbit - obviously an important part of the mission.

NASA has assured everyone that TESS is fine, so don't worry. We'll hopefully see her begin its hunt for new habitable worlds outside our Solar System soon.

In the meantime, we'll keep you updated with the latest details as they come in.

When the launch does happen, you'll be able to watch it live here.
