Revised: Feb 08, 2018 Tesla Roadster (spacecraft) -143205
(solution #3)

Tesla Roadster (AKA: Starman, 2018-017A)

NOTE:
The trajectory estimate will be updated here in the days ahead if more
measurement data is reported.

LAUNCHED:
2018-Feb-06 20:45 UTC by Falcon Heavy (FH) from Kennedy Space Center, USA
(launchpad 39A)

BACKGROUND:
Dummy payload from the first launch of SpaceX Falcon Heavy launch vehicle.
Consists of a standard Tesla Roadster automobile and a spacesuit-wearing
mannequin nicknamed "Starman".

Also includes a Hot Wheels toy model Roadster on the car's dash with a
mini-Starman inside. A data storage device placed inside the car contains
a copy of Isaac Asimov's "Foundation" novels. A plaque on the attachment
fitting between the Falcon Heavy upper stage and the Tesla is etched with
the names of more than 6,000 SpaceX employees.

After orbiting the Earth for 6 hours, a third-stage burn-to-depletion was
completed at approximately 02:30 UTC Feb 7, placing the dummy payload in
a heliocentric orbit having a perihelion of 0.99 au and aphelion ~1.7 au.

PAYLOAD MASS:
~1250 Kg

TRAJECTORY:
This trajectory is based on JPL solution #3, a fit to 57 ground-based
optical astrometric measurements spanning 2018 Feb 8.2 to 8.8.

Trajectory name Start (TDB) Stop (TDB)
-------------------------------- ----------------- -----------------
tesla_s3 2016-Sep-09 07:00 2017-Dec-01 00:01

If you wish to propagate statistical uncertainties for this object (it being
a man-made object and so not part of the asteroid and comet database which
normally holds solution covariance data), the full statistical orbit solution
can be manually cut-and-pasted back into Horizons as a user-defined object
using the telnet or e-mail interfaces.

To do this and activate statistical output:

Using the telnet interface (command-line "telnet ssd.jpl.nasa.gov 6775"),
enter ";" to drop into user-input mode then cut-and-paste each line shown
below, one at a time. The lines after SRC must be in the order shown.

Press a blank return to exit input mode when done. Enter "J" at the prompt
to indicate heliocentric J2000 ecliptic data has been supplied. Then input
an arbitrary name (i.e., Roadster).

Horizons will then proceed as usual, but with statistical output now
available (covariance mapping).

An identical tracking ephemeris can be produced without doing this, but
statistical uncertainty quantities requested will be marked "n.a.", meaning
not available.

Over time, prediction errors could increase more rapidly than the formal
statistics indicate due to unmodeled solar presure, thermal re-radiation,
or outgassing accelerations that are not currently characterized.

Tesla Roadster & Starman photographed at a distance of 493,000 km as a star of magnitude 16, and a second observation a few hours earlier, both from Australia.

Deimos Sky Survey captures SpaceX’s Starman Tesla Roadster / Falcon Heavy Upper Stage

Deimos Sky Survey obtains new images of SpaceX’s Starman-driven Tesla Roadster at 720000 km from Earth

http://www.elecnor-deimos.com/images-spacex-starman-tesla-deimos-sky-survey/

Elecnor Deimos Space Surveillance and Tracking Centre, Deimos Sky Survey (DeSS), has obtained new images of the Spaceman-driven Tesla Roadster on its way to Mars. It has been confirmed that the vehicle is still attached to the upper stage of SpaceX’s Falcon Heavy launcher.

The images, whichcaptured the vehicle at a distance of 720.000 km from Earth (almost twice the distance of the Moon), show a flickering effect that suggests that the Tesla Roadster is spinning fast.

PS This is the last time we'll have a thread that will include one post of congrats. That will take place in the discussion or party threads from now on.

We started that because people wanted to have their name on a historic thread that is like a "I was there" style post, so I didn't want to change that for Falcon Heavy, but that will be the plan from this point onwards.

Update threads will be updates only, although I know it won't stop people completely ignoring that and posting non-updates on update only thread.

Complete SpaceX Falcon Heavy Launch to Landing Footage: Enhanced Edition

Astronomy Live
Published on Feb 9, 2018

I did some tweaking to color, contrast, and the audio (removed the annoying slew tone emitted by the telescope, thanks to the various posters who gave me the frequency to eliminate). Tracked using Teletrak and captured with an 8" LX200 Classic. Recorded with a Canon T5i @ f/6.3

For all the Falcon Heavy fans with a 3D printer: it's now possible to get a model of the FH fairing.

Pics from Bill Carton on the Facebook group showing one side booster (I think the right), being rolled into the HIF.

Vid I shot of the launch from Playalinda Beach. Lot of ground haze and a really long lens, but the sounds is amazing.

National Geographic has exclusive behind the scenes footage of Elon during FH launch:

Edit to clarify:

There’s a 90s clip at the above link, with more footage to be part of Mars season 2.

Nice light curve of it spinning. Interesting question: there's a bunch of asteroid software that infers shape from light curves ... wonder how well it will do on this?

Early this morning we measured the brightness changes of a car tumbling in space! Credit to Erik Dennihy (@UNC), we can report that Tesla Roadster (Starman, 2018-017A) is rotating with a period of 4.7589 +/- 0.0060 minutes. https://t.co/LA4YzdvjK9

Didn't recall seeing this in all the excitement this past week...

This is a neat view... maybe the closest one of the booster landings - taken from the Delta IV launch tower:

(Although the guy recording missed the landing moment in his excitement)

EDIT: Here is a different version (better sound) captured by a person right next to the one above:

The dual booster return and landing still stuns me. People will be watching that video decades from now and be just as impressed.

I hold out hope that we’ll see a 3 core RTLS for some FH missions.
