# What secondary payloads, if any, are launching on the inaugural flight of Falcon Heavy?

Overshadowed by a silly, yet awesome primary payload — 'a cool colored cool electric sports car playing a cool track' on to a heliocentric orbit, are there other satellites/secondary payload Falcon Heavy would lift on it's maiden flight?

I know of Planetary Society's LightSail 2, for one.1

Has there been a mention of any other secondary payloads? Also, information on orbits of secondary payloads and speculation of deployment sequence, if possible.

EDIT

1. LightSail 2 is scheduled for and April launch.
• One might think that they may be a bit sceptical about the launch's chances for success. It is essentially a test flight after all. If they kill a few million dollars worth of spacecraft - oops. But a car? no big loss. They can just build another. – Baldrickk Jan 3 '18 at 13:55

There are no known secondary payloads flying on the Falcon Heavy maiden flight. Excluding what's in the Roadster's glove box... ;)

Planetary Society's LightSail 2 is flying on the Space Test Program-2 (STP-2) mission of Falcon Heavy, the third flight, notionally penciled in for April 15, 2018. Other smallsats flying on this launch include the Green Propellant Infusion Mission, which itself is quite interesting.

Let's look at the picture as seen from the side (Not official photograph, but...

If there was going to be a secondary payload, it would have to be between the car and the payload adapter. There clearly isn't room there to do so.

I've heard rumors that there could be a second point where secondary payloads might reside. There is an open space near the engine that could host a small payload. This was a possibility some years ago, but I haven't found anything to be the case more recently. As Kuldeenp answered, there doesn't seem to be any other payloads indicated on this particular flight.

• +1 I was about to ask if "the engine" refers to the payload's engine (first photo) or the 2nd stage engine (2nd photo) until I realized the Tesla has no engine. – uhoh Jan 5 '18 at 2:11
• Right, it has electric motors, no engines. – PearsonArtPhoto Jan 5 '18 at 2:49
