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)  ;)



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.

So...   how does one gain access to the Delta IV launch tower during SpaceX flight operations?
Being discussed in the Discussion thread where this discussion should be.

Elon's Roadster is now at 1.6 million km from Earth, outside the Earth-Moon System's Hill sphere and so firmly in solar orbit

For the record, Tesla's closest approach to the Moon was 0220 UTC Feb 8 at 140,000 km which isn't terribly close but probably enough to affect the trajectory slightly  (2 lunar Hill radii)

Starman Isn't Headed for the Asteroid Belt

"The asteroid orbit plot was just a mistake," Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, told Space.com.

McDowell explained that the error apparently arose when someone at SpaceX used an orbital parameter called C3 — a measure of the velocity needed to escape Earth's gravity — to determine the shape of the Roadster's orbit "and goofed while doing it."

"For selling the rocket to customers, C3 is what you care about, [and] the actual orbit around the sun is not relevant," McDowell said, "so they weren't careful about calculating it."

Quote
McDowell calculated that the Roadster will venture by Mars at a safe distance of about 70 million miles (110 million kilometers) as it crosses the planet's orbit in July.

The closest it will ever get to Mars will be in October of 2020 at a distance of about 4.4 million miles (7 million km), which is still "well outside Mars' gravitational sphere of influence," McDowell wrote on Twitter. This means that the Roadster definitely won't be orbiting Mars as Musk first announced it would in a tweet last December.

Not enough ignition fluid to light the outer two engines after several three engine relights. Fix is pretty obvious.

The centre core landing failure was caused by the fact that the need for ignition fluids (TEA/TEB) increases after several engine relights. They are adding more storage to fix the issue.

Tesla Roadster & Starman spotted at a distance of 1 mln km on Feb 10 (magnitude 17).

3 new photos of the launch by Ben Cooper have been added to the official SpaceX Flickr account yesterday:

Also I found the launch photos collection (on Flickr) from NASA KSC to be pretty good - I especially like the roll-program underway one.

Tweeted it but forgot to post in the updates (usually it's the other way around)....Pad 39A shakedown report looks pretty good post Falcon Heavy.

I guess this will the final view of the Tesla Roadster & Starman. It was taken on Feb 13, at a distance of 2 mln km (magnitude 19).

Amateur astronomers all around the world try to capture a final image of the Tesla Roadster & Starman. The record so far (as far as I know) is posted below: distance 2½ mln km on Feb 15, at magnitude 19.3

Congrats to SpaceX and the really exemplary entrepreneurial vision and execution by Elon Musk and the outstanding engineering and others team they have assembled!

I was in traveling in continental Europe for a couple of weeks, arranged a big screen for the launch, and thought I'd have just a few of my colleagues join me for an exciting launch party on the evening.  Instead, even with our CEO having a scheduled "fireside chat" in the hotel room next door to the room I'd arranged, we had 70 join us standing-room-only in the smaller room and wildly cheer the launch and landing from Portugal.  Really great work SpaceX!!!

A surreal and wonderful experience for me.
Re arguments from authority on NSF:  "no one is exempt from error, and errors of authority are usually the worst kind.  Taking your word for things without question is no different than a bracket design not being tested because the designer was an old hand."
"You would actually save yourself time and effort if you were to use evidence and logic to make your points instead of wrapping yourself in the royal mantle of authority.  The approach only works on sheep, not inquisitive, intelligent people."

Thanks for sharing this here!  I took this image set at the McCarthy Observatory, thinking it was close to as deep as our little 406mm telescope could see (at 72m elevation in a river valley, with the roadster transiting at 20 degrees in altitude).  We went after the roadster again Saturday morning, and found it again at magnitude 19.7!

Monday early morning we're going to take one more shot at it (projected magnitude 19.84).  One of our volunteers was at the Cape for the launch, and it's been a blast tracking Stage 2's journey through the solar system so far.  The public interest this has generated is fantastic, it has really captured the imaginations of so many people!

I ran over to KSCVC and took a few pics of the side core booster on display.
