I'm going to guess the car will remain attached to the second stage? It seems like this might be the case as they made big deal of the signatures on the adapter the car is attached to. It would make sense to keep the two together.

Has anybody calculated the predictions on when it will be back in our neighborhood?
I use the "Starry Night" software for future astronomical events. Is there any way to input the data into the program? I guess I could check to see if I could download some updates that might include this data.

Bill Harwood, reporting for CBS, wrote about the Roadster's journey based on the orbital data shared by SpaceX with Jonathan McDowell.
It will pass within about 69 million miles of Mars on June 8 and cross the red planet's orbit in July before reaching its farthest distance from the sun — about 158 million miles — on Nov. 19.
After that, the Roadster and Starman will fall back toward the inner solar system, picking up speed as they near the low point of the orbit, or perihelion, on Sept. 1, 2019. Perihelion in this case roughly matches the distance of Earth's orbit from the sun, the Tesla's starting point. The Roadster then will head back out along the same path, traveling a now-familiar route over and over again for the foreseeable future.
That gives the timeline, but doesn't answer if Earth will be anywhere near where the Roadster next crosses our planet's 1 AU orbit.
The Roadster has been added to JPL's Horizons — target body -143205 — which may help with answering that question.

Yes, the Roadster and the second stage are still and forever mated.

I am assuming that is the cost on top of the money already spent on the Falcon 9 vehicle development and launch infrastructure.

Teslas don't weigh as much as the full payload that the Heavy can carry, so where is the rest of the mass? Just the rocket stage as well?

I just saw this Yahoo article questioning the recovery of the core stage. Can anyone confirm whether the booster was towed back or recovery of any pieces after a possible bombing/airstrike by US military?
According to Musk's twitter of the core stage, all the recovery in the water was planned. What is the question is the retrieval of the booster by watercraft either towed or sunk by the military.

That was for SpaceX's other launch on Jan. 31, not the Falcon Heavy/Tesla launch. The core of the Jan. 31st launch was a water landing.

The following statement was provided to Florida Today from SpaceX:
While the Falcon 9 first stage for the GovSat-1 mission was expendable, it initially survived splashdown in the Atlantic Ocean. However, the stage broke apart before we could complete an unplanned recovery effort for this mission.
Reports that the Air Force was involved in SpaceX's recovery efforts are categorically false.
The center core from the Falcon Heavy launch was intended to land on the droneship but failed. The droneship is now back at the port.

I saw that the other day and enjoyed it, too. Loved seeing the inside of the VAB from different perspectives. And of course the focusing in on the sound aspects of a launch was great.
Wish that guy had been around for the Saturn V launches. I saw Apollo 17 from Titusville and whenever I retell the story, my main point is about the sound that could be felt! Thanks for posting.

National Geographic has released footage they shot for the second season of "MARS" showing Elon Musk witnessing the Falcon Heavy launch.
"Holy flying f--k, that thing took off," Musk exclaimed. Moments later, he and SpaceX staffers ran out the door of the launch control center and turned their gazes upward. "Look at that! That's unreal!" Musk cried out.

I think it would have been fun to have had a second spacesuited figure in the passenger seat. That famous red spacesuit worn by the crew of Discovery in 2001: A Space Odyssey.

This video of the two side cores landing taken from a distance is pretty impressive — seeing them drop in so fast and then hearing the sonic booms and the sound of the engines...

Based on the LC-34 that is seen in the foreground I think it would be LC-37 or the Delta IV launch area that is just north of the LC-34.

I had not noticed this in other videos of the FH launch but in this video (posted by teopze above) just after launch (at approximately 3:31 in the video) the booster closest as viewed appears to have a small plume on its left side (as viewed). As the FH accelerates (at 3:42+ in the video) the plume appears to disappear.
I am trying to understand if this is a turbopump exhaust plume or some type of steering vernier or anomaly? If normal would this plume be apparent on Falcon 9 (non-heavy) launches?

One of the Falcon Heavy's two recovered boosters has been put on brief temporary display at the Kennedy Space Center Visitor Complex in front of the Space Shuttle Atlantis building for this week's National Space Council meeting.
Below photo credit Stephen C. Smith on Twitter, where he also posted two video walkarounds: 1 | 2.
Update: From Kennedy Space Center Visitor Complex on Twitter:
Calling all SpaceX fans! For the next few days, a recycled first stage Falcon9 rocket that launched and landed on two SpaceX missions, including Falcon Heavy, will be on display in front of Space Shuttle Atlantis at Kennedy Space Center!

U.S. Air Force Space Command release
Tracking the billion year road trip
Cruising with the windows down, music up and the Sun shining on your face. Going on a road trip is an adventure that some people love or aspire to do. For one individual, their road trip could last a billion years, and the 18th Space Control Squadron is tracking it.
His name is Starman, and he's currently cruising through our solar system in a bright red car. He's got one hand on the steering wheel and the other resting on the door while David Bowie's "Space Oddity" blasts from his radio. The Sun is a constant light shining on him during his journey, and the first stop on his adventure is a fly-by of Mars, then a visit to the beginning of the asteroid belt before returning to Mars in an elliptical orbit. A sign on his dashboard reads, "Don't panic!"
Starman is not really a man, however, but rather a dummy in one of SpaceX's new space suits.
SpaceX launched their Falcon Heavy rocket on Feb. 6, 2018, which is now the most powerful launch vehicle in operation in the world. SpaceX owner and CEO, Elon Musk, said in an interview with a national news network, "Test vehicles usually carry concrete or steel blocks, but that would be extremely boring. We decided to send something unusual, something that made us feel."
That choice was Musk's own personal car, with Starman onboard.
Enter the mission of the 18th SPCS located at Vandenberg Air Force base, California, a geographically separated unit of the 21st Operations Group, 21st Space Wing, Peterson Air Force Base, Colorado. Their mission is to maintain the satellite catalog by processing observations of objects launched into space, currently on orbit, or re-entering the Earth's atmosphere, including more than 1,400 active objects and 22,000 pieces of debris.
As objects in space orbit the Earth, like a bright red car, three Ground-based Electro-Optical Deep-Space Surveillance Sites, or GEODSS, collect positional and photometric data said Maj. Erin Salinas, Detachment 1 commander, 20th Space Control Squadron.
"We have to know where things are in space in order to know what is going on around us," Salinas said. "Our data helps maintain the advantages space is providing us, in not just our everyday life as civilians, but with our military capabilities as well."
As Flacon Heavy left Earth's atmosphere and delivered its payload into orbit, the GEODSS track its position. The car's positional data is then relayed to the 18th SPCS and they assign it a catalog number. Diana McKissock, 18th Space Control Squadron Spaceflight Safety and SSA Sharing Flight Lead, says you can see this information on Space-Track.org.
"The car's number is 43205, named 'TESLA ROADSTER/FALCON 9H' in the satellite catalog," said McKissock.
Far above the world, floating in a peculiar way, Starman sits in a tin can. There's nothing he can do with Earth looking blue in his rear-view mirror, but the men and women of the 21st Space Wing are tracking his journey. A testament to the abilities of our space situational awareness mission and the Airmen that bring space superiority to the fight every day.

From Elon Musk on Twitter:
Why Falcon Heavy & Starman?
Life cannot just be about solving one sad problem after another. There need to be things that inspire you, that make you glad to wake up in the morning and be part of humanity. That is why we did it. We did for you.
The video, edited by Jonathan Nolan (Christopher Nolan's brother) debuted at SXSW on Saturday (March 10).

And confirmed by SpaceX (also via Twitter):
Starman, last seen leaving Earth, made its first close approach with Mars today — within 0.05 astronomical units, or under 5 million miles, of the Red Planet.
