I'm 2 degrees of latitude north of the potential impact zone.

Hydrazine fuels have some level of nitrosamines, which are quite carcinogenic. However, in the case of satellite re-entry, you have to consider that this is rocket fuel and it will very easily be completely burned up (much more easily than the aluminum that makes up the bulk of the space station).

TESS satellite launch today from NASA website:

"The planned liftoff of a SpaceX Falcon 9 rocket carrying NASA’s Transiting Exoplanet Survey Satellite, or TESS, remains scheduled for 6:32 p.m. EDT Monday from Space Launch Complex 40 at Cape Canaveral Air Force Station. Meteorologists with the U.S. Air Force 45th Space Wing continue to predict an 80 percent chance of favorable weather for liftoff." - NASA

Very excited to see it. TESS itself is the size of a small fridge; the pictures of it inside the newer, larger fairing 2.0 are quick comical.

Totally! We'll be in Titusville on the 15th and I'm renting a car. We can talk details via PM.

Pleasure meeting you today DrFish. Good to geek out every once in a while with fellow rocket enthusiasts.

Likewise! And thanks again for lunch. Here's a link to the best of my photos from our day at KSC. Still pretty bummed the launch was scrubbed, really felt the hole-in-your-chest phenomenon. It will be bittersweet to watch the stream when it launches today or later on...

Here's a gallery of 360 photos from my Theta S. Quality isn't as nice, and Google's handling of 360 photos could use some work, but it's better than nothing and I'm too lazy upload each one individually to the Theta viewer. Personally, I think they look a lot better when viewed zoomed out, and at about 1/4 of your screen size.

I'm excited too. I'd take time off work, but since I just took off last friday and have the next 2 Friday's off, that was hard to swing. I'll probably watch it from the driveway with the 120" projector through the window. Best of both worlds.

Not new news, but I just saw that SpaceX has set a date for Mars landing in 2020 for its BFR rocket. My thoughts are that sounds like a better date for the BFR first test flight. With a moon landing in 2021. That is unless it blows up, ah, I mean rapidly dissembles. Then 2022 for a Moon landing. That is something I would like to see, a single stage take off and landing on the moon. Mars seems like a fantasy to me. SpaceX's website has a very entertaining video on it's site explaining the the timeline.

Maybe more realistic use for his BFR would be a new space Telescope or a Hubble upgrade mission. Looks like overkill for missions to the international space station. SpaceX's Falcon 9 looks to be an excellent workhorse and even if SpaceX goes bankrupt trying to build a BFR, Falcon 9 style boosters are sure to have a place the future.

Saw this courtesy of Ar's rocket report. I love it, what an upgrade. I can't wait for the next faring recovery attempt.

I keep hoping they'll bring it to the East Coast so I can see it. No luck so far though. The next launch is on my birthday! Unfortunately it is as ~2am (+/- 3 hours) and I'll have just gotten back from Europe 6 hours prior, so it'll be rough. We'll see. I love night launches. They go from dark to light. I have pictures from the last launch that came out great.

Now officially 6:50am. I think we can do that. My kids were severely disappointed I didn't wake them up for the last launch, so we'll do it right this time.

My first thought is that it's a little bonkers they can download that much data that quickly at all let alone from a thing that's in space.

At the frequency they use earth orbit is pretty close and the atmosphere is transparent. Plus the signal strength gain and high S/N ratio of a parabolic dish or parabolic dish array is considerable. I would expect upload speed to be quite a bit slower.

That's why it is in the orbit it is. It doesn't have to go through the Deep Space Network. It can use much higher bandwidth shorter distance communication. BTW, the DSN was talking to voyager 1 and 2 last night while TESS was uploading. I found that really stinking cool.
