What happened to the Tesla that Elon Musk shot into space?

Because of how the car's projected orbit aligns with Earth's orbit, astronomers on the ground probably won't be able to spot the roadster again until late in the 21st century. Based on calculations he made Thursday, Langbroek predicted that could happen in 2073. But in an email on Friday, he said it still seemed the car's path was "too ill defined to make reliable forecasts."

Sorry if this has been posted earlier but the videos of the boosters landing is every bit as stirring as the launch --quite a bit more for me if I'm honest. I could watch this all day.

Oh man thanks for sharing that compilation. I only watched it live and of course they cut to the external camera at last second so it was over almost instantly.

This gave me chills every time a new angle showed them. Wow. If that doesn’t inspire tons of kids to get into astrophysics, engineering or related, I don’t know what will.

Where is Elon Musk's Tesla Roadster with Starman?
But where is this vehicle? The current location is 1,501,063 miles (2,415,728 km, 0.016 AU) from Earth, moving away from Earth at a speed of 6,830 miles/hour (10,992 km/hour, 3.05 km/s).

The car is 141,729,821 miles (228,092,107 km, 1.525 AU) from Mars, moving toward the planet at a speed of 43,686 miles/hour (70,305 km/hour, 19.53 km/s).

The car exceeded its 36,000 mile warranty 282.6 times while driving around the Sun, (10,172,638 miles, 16,371,280 km, 0.11 AU), moving at a speed of 56,069 miles/hour (90,234 km/hour, 25.07 km/s).

Nice. They do say electric cars should last longer than ICE vehicles...

The SpaceX news is tough to keep up with these days. Over at Ars, Eric Berger details just how royally fucked the incumbents are by SpaceX and likely Blue Origin in a few years (the article slug tells it all: three-years-of-sls-development-could-buy-86-falcon-heavy-launches).

Also, SpaceX will launch its first two satellite broadband devices over this coming weekend. SpaceX eventually plans to have more than 4,000 satellites in orbit, at a much lower altitude than existing [terrible] satellite broadband providers. Think Comcast-level speeds and latency but anywhere on the planet and likely cheaper. Obviously assuming that will happen at this stage is very premature, but it's another industry that SpaceX could conceivably drastically undercut in a decade or so.

Falcon 9 Block 5
The newest iteration of SpaceX's workhorse Falcon 9 rocket will make its debut today (May 10), and you can watch the maiden liftoff (and landing attempt) live.

The first "Block 5" Falcon 9 is scheduled to launch the Bangabandhu 1 communications satellite for the government of Bangladesh today at 4:12 p.m. EDT (2012 GMT) from NASA's Kennedy Space Center in Florida. And the two-stage rocket's first stage will attempt to land on a robotic "drone ship" off the Florida coast shortly after liftoff. You can watch the action live here at Space.com and on our homepage, courtesy of SpaceX, or directly via SpaceX's website.

The launch window opens at 4:12 p.m. EDT and runs until 6:22 p.m. EDT (2222 GMT). There's just a 20 percent chance that bad weather will spoil the attempt, officials with the U.S. Air Force’s 45th Weather Squadron said on Monday (May 7).

The Block 5 features a number of upgrades that should increase the rocket's reliability and reusability, SpaceX officials have said. The first stage of the Block 4 Falcon 9 is limited to two launches, but the Block 5 first stage should be able to lift off 10 times — with just inspections between landing and launch — and up to 100 times with some refurbishment, according to company representatives. (SpaceX has stated a desire to reuse the two-stage Falcon 9's upper stage at some point, but hasn't made a concerted attempt to do so yet.)

Inside the eight desperate weeks that saved SpaceX from ruin. Good piece detailing the 2008 near-RUD of SpaceX itself.

Crazy water landing today. Sounds like despite the grid fin failure and spin-out, they managed to recover and 'land' in the ocean. They're picking up the rocket and may use it for a StarLink mission in the future. Spooky video, though, and was even more spooky live when it looked like they might crash-land on land.

External video. I bet that if they had tried this on the pad, it'd have stayed up. Understand why they didn't, though.

Wired
In February 2017, a SpaceX Falcon 9 rocket lifted through low clouds, pushing a Dragon capsule toward orbit. Among the spare parts and food, an important piece of scientific cargo, called SAGE III, rumbled upward. Once installed on the International Space Station, SAGE would peer back and measure ozone molecules and aerosols in Earth’s atmosphere. Its older siblings (SAGEs I and II) had revealed both the growth of the gaping ozone hole and, after humans decided to stop spraying Freon everywhere, its subsequent recovery.

This third kid, then, had a lot to live up to. Like its environmentally conscious predecessors, SAGE III is super sensitive. Because it needs unpolluted conditions to operate optimally, it includes contamination sensors that keep an eye on whether and how its environment might be messing up its measurements. Those sensors soon came in handy: When the next three Dragons docked at the Space Station, over the following months, SAGE experienced unexplained spikes in contamination. Something on these Dragons was outgassing—releasing molecules beyond the expected, and perhaps the acceptable, levels. And those molecules were sticking to SAGE.

Now, this is what a spaceship should look like. The real vehicle is on the left and the concept drawing on the right. This is a short-hop test vehicle; the orbital version will have a thicker, smoother skin that looks more like the illustration, and is expected to fly in 3-4 years.

I have questions about the Tesla car in orbit. Wouldn't the tires blow up in the vacuum of space? Wouldn't the body be scarred from micro meteorites?

I don't believe they plan to drive it again. ;) The plan is for it to get toasted.
