Boo. I'll update the OP shortly.

Looks to me like they imposed the building and the water tower in to be closer to the pad than it would really be.

BleedingRed 02-21-2018 09:05 AM

What are they launching?

A rocket!

allen_kcCard 02-21-2018 09:09 AM

Or....from the Next Launch Details in the OP:


Feb. 21 Falcon 9 • Paz
Launch time: 06:17 PST / 14:17 UTC
Launch site: SLC-4E, Vandenberg Air Force Base, California
A SpaceX Falcon 9 rocket will launch the Paz satellite for Hisdesat of Madrid, Spain. Built by Airbus Defense and Space, Paz carries a radar imaging payload to collect views of Earth for government and commercial customers, along with ship tracking and weather sensors. Multiple smaller secondary payloads will also launch on the Falcon 9 rocket. The Falcon 9 rocket will launch with a previously-flown first stage.

Na, that's where they're located. The angle makes the building (HIF) look a little closer than it is, but it's only a quarter mile away. And the water tower is what powers all of the "rain birds" that deluge the base of the pad on launch, so it's very close.

You can see the layout on the satellite view. HIF is straight south, water tower is northeast.

I went ahead and added the next launch to the OP (for late Saturday night) since these two will be pretty close together. Could get even closer if Paz continues to have weather issues.

be able to deliver some 70 tons to low-earth orbit, or less than 20 tons to Mars, while costing around $150 million per mission. According to Musk, the rocket cost somewhere north of $500 million to develop.

Then look at the Space Launch System (SLS) being built under NASA’s instruction by Boeing, also to explore the solar system. According to the new NASA budget released last week, it will fly for the first time in 2020, capable of carrying some 77 tons to low earth orbit at a cost of about $1 billion a flight.

LMAO

yeah, the cost of SpaceX is shockingly cheap compared to NASA.

I don't think SLS is quite dead, but it's got some major issues moving forward. It's pretty clear at this point that there's just too much bureaucracy involved at NASA to be competitive with commercial launchers. Once there's another heavy lift vehicle out there (New Glenn most likely), SLS is gonna be pretty damn useless.

This article lays it all out in (almost nauseating) detail.

https://arstechnica.com/science/2018...eavy-launches/

Quote:

For the sake of argument, consider the costs of this three-year delay against the lift capability NASA could have bought by purchasing Falcon Heavy rockets from SpaceX in 2018, 2019, and 2020. That $7.8 billion equates to 86 launches of the reusable Falcon Heavy or 52 of the expendable version. This provides up to 3,000 tons of lift—the equivalent of eight International Space Stations or one heck of a Moon base. Obviously NASA does not need that many launches, but it could buy several Falcon Heavy rockets a year and have the funds to build meaningful payloads to launch on them.

So what are the collective thoughts on how Neil Armstrong and Neil Degrasse Tyson have been so damning of Space-X?

I think those guys have been douchebags, and I'm really happy Elon keeps proving them wrong.

I think part of it is old news and part of it is people taking quotes out of context. Armstrong's comments came in 2012 before the first Dragon had ever launched to ISS, let alone all the progress with rocket reusability. Even then, he wasn't happy with the way his comments were portrayed.

Quote:

It isn't everyday that you get a letter from Neil Armstrong, yes, that Neil Armstrong. And it's particularly noteworthy when the first man to walk on the moon has a bone to pick with you. Armstrong wrote us recently about a story we did for 60 Minutes on Elon Musk and his SpaceX Corporation. ....

Armstrong wrote us to say we had not been complete in our description of his testimony. He's right. When you look at what Armstrong said to Congress, you see that while he was "not confident" that the newcomers could achieve safety and cost goals in the near term, he did want to "encourage" them. We should have made that clear in our 60 Minutes report and in our story on The CBS Evening News. Also, we should have spelled out that his concerns were directed toward the "newcomers" in general and not SpaceX in particular.

Scott Pelley Managing Editor, The CBS Evening News Co-Editor, 60 Minutes

As for NGT, he has a tendency of trying to be a bit controversial for the publicity IMO. Even then, his actual stance is just that SpaceX won't get to Mars without NASA's help. And I don't disagree with that. NASA's role is obviously shifting, but they're still critical to space exploration.

Quote:

"I'm simultaneously one of SpaceX's biggest critics and supporters," he said in response to a question about how advances such as SpaceX's reusable rockets will affect humanity's efforts to get to Mars in the near future.

Projects "that are hugely expensive and dangerous, with uncertain returns on investments, make poor activities of profit-driven companies," Tyson added. "Governments do these things first, allowing private enterprise to learn what to do and what not to do, then come next with a plan that involves us all. So my read of history is that private companies will not be the first to send humans to Mars unless government actually pays for it.

Nice article!

I thought this was awesome:

Quote:

Significantly, the Merlin engines—like roughly 80 percent of the components for Falcon and Dragon, including even the flight computers—are made in-house. That’s something SpaceX didn’t originally set out to do, but was driven to by suppliers’ high prices. Mueller recalls asking a vendor for an estimate on a particular engine valve. “They came back [requesting] like a year and a half in development and hundreds of thousands of dollars. Just way out of whack. And we’re like, ‘No, we need it by this summer, for much, much less money.’ They go, ‘Good luck with that,’ and kind of smirked and left.” Mueller’s people made the valve themselves, and by summer they had qualified it for use with cryogenic propellants.

“That vendor, they iced us for a couple of months,” Mueller says, “and then they called us back: ‘Hey, we’re willing to do that valve. You guys want to talk about it?’ And we’re like, ‘No, we’re done.’ He goes, ‘What do you mean you’re done?’ ‘We qualified it. We’re done.’ And there was just silence at the end of the line. They were in shock.” That scenario has been repeated to the point where, Mueller says, “we passionately avoid space vendors.”

It's pretty clear that they at least considered the angles for photos when they built out the structure. Elon absolutely considers the marketing aspects of everything he does. (See: Roadster on a rocket.)

The MicroSat 2a and 2b are two identical satellites to test technologies for SpaceX's planned 4425-satellite Starlink constellation to provide broadband Internet access.

These satellites replace the MicroSat 1a and 1b microsatellites as the first test satellites for the SpaceX constellation. The first phase of testing will include two satellites: Microsat-2a and Microsat-2b. These two satellites are intended to be launched as early as 2017.

Both of these satellites will be deployed in one mission aboard a SpaceX Falcon-9 v1.2 launch vehicle into an orbital plane of 514 km circular at 97.44 degrees inclination. After insertion, the satellite orbits will be raised to the desired mission altitude of 1125 km circular. The designed lifetime of each satellite is six months. If this lifetime is exceeded, SpaceX plans to continue operation until such time as the primary mission goals can no longer be met, at which point the spacecraft will be deorbited. Both Microsat-2a and Microsat-2b are identical in their construction and operation.

The primary structure for the Microsat-2a and -2b test spacecraft will be a box design measuring 1.1 m × 0.7 m × 0.7 m and carries the spacecraft flight computer, power system components, attitude determination and control components, propulsion components, GPS receiver, and broadband, telemetry, and command receivers and transmitters. The primary bus is mounted on the payload truss system, which also carries communications panels, inter-satellite optical link transmitters and receivers, star trackers, and a telemetry antenna. There are two 2 m × 8 m solar panels. Each demonstration spacecraft has a total mass of approximately 400 kg. The attitude of each spacecraft is 3-axis stabilized, and is dynamically controlled over each orbit to maintain attitude position for two pointing modes of operation: broadband antenna (antennas to nadir for testing) and solar array (solar arrays facing sun for charging). Power is provided by solar panels designed to deliver sufficient power at the predicted end of spacecraft life to not impair any test objectives. The Thermal Control System ensures that components are kept within operational temperature ranges.

In addition to proving out the development of the satellite bus and related subsystems, the test program for the Microsat-2a and -2b spacecraft will also validate the design of a phased array broadband antenna communications platform (primary payload) that will be included in the final spacecraft design for the proposed NGSO constellation. SpaceX intends to test the Microsat-2a and -2b communication paths utilizing five broadband array test ground stations located in the western United States, as well as three transportable ground stations that will be deployed near the fixed ground station locations, all within the contiguous United States (“CONUS”). With the orbit profile provided, broadband array tests (Ku-band) will be conducted on average once every 0.9 days for less than 15 minutes. The primary Telemetry, Tracking, and Command (“TT&C”) ground station will be located near the primary test site in Redmond, WA to facilitate and control the broadband array testing. The testing will help to validate a number of design parameters.

I wish I had a way to post this without a bump, but since I wasn't the last post otherwise, here's a bump to say that the thread shouldn't be bumped this weekend after all.

There are rumors that Hispasat may launch in the next couple days, but nothing definitive. I'll bump the thread when we know.

Unrelated, the first Block 5 F9 is on the test stand. Looks like it's gonna be a more black and white rocket moving forward rather than just white. The legs will be black too. (The yellow cap on the top is just to hold it down during testing.)

https://www.nasaspaceflight.com/wp-c.../02/Block5.jpg

This probably isn't 100% accurate, but here's a brief synopsis of what people THINK the upgrades are:

https://www.reddit.com/r/spacex/comm..._readying_for/

Quote:

  • Titanium grid fins for unlimited re-uses.
  • New landing legs with the ability to be retracted by the ground crew instead of having to be removed after landing. These legs will also be black instead of white.
  • Changes to the turbopumps to prevent turbine wheel microfractures. This was never considered a risk by SpaceX but NASA asked SpaceX to fix the issue and from all reports they have.
  • Replace paint with thermal protection barrier coating for the purposes of re-use.
  • Improved heat shielding around the engines to improve re-usability.
  • The octoweb (structure that holds the engines) will be bolted instead of welded, to reduce time for inspection/repair/refurbishment and to allow easy change from F9 to FH side booster.
  • The interstage will be black instead of white - likely unpainted carbon fiber (saves time and weight).
  • Upgraded fairing, Fairing 2.0, which is very slightly larger and has changes to allow for recovery and re-use. It is also easier to make and lighter than the previous fairings.
  • SpaceX's upgraded COPVs (dubbed COPV 2.0) will fly on Block V. This is an upgrade to further reduce the potential for an incident like Amos-6.
    Another improvement in thrust for the Merlin 1D engines (roughly 10%).
  • The rocket will be man-rated, meaning it will be certified to carry crew. NASA has set the bar at 7 successful flights of the rocket for certification.
  • Upgrades to valves, seals, and many other parts to allow for many re-uses.
  • Improved flight control, angle-of-attack, and control authority which should allow for landings with less fuel (and therefore the ability to land after lofting heavier payloads).

To summarize, they essentially made many interior parts to a significantly higher durability level, replaced the grid fins and landing legs with versions that are more durable and easier to reuse, significantly improved heat shielding over the entire vehicle - but focusing specifically on the engines - to limit needs for refurbishment, and made the engines easier to inspect/repair/refurbish by bolting instead of welding the octoweb. Then, due to improved flight control authority and thrust, they ensured that they should be able to land more of their missions.

Next FH launch is officially slated for June.

https://spaceflightnow.com/2018/03/0...-heavy-launch/

In short, 25 different satellites all in one launch. Should be a hell of a deployment to watch if nothing else.

Also, Hispasat is officially on for Monday night.

aturnis 03-02-2018 05:03 PM

Oh wow. Are they launching someone else's satellites, or their own?

Or I suppose, most likely, both?

I don't THINK any of them will be more test sats from SpaceX themselves. Sounds like it's a couple of Air Force satellites plus probably a barrage of cubesats from universities and such.

DaFace 03-05-2018 10:06 AM

Heads up that Hispasat should be flying late tonight. Recovery attempt has apparently been called off due to poor conditions at the landing site, so that'll be interesting to see how they handle it.

SpaceX aims for 3 rocket launches in a single week, 6 launches in 1 month
By Eric Ralph
Posted on March 8, 2018

Tailing an intense February that saw SpaceX successfully complete inaugural launches of both Falcon Heavy and two Starlink prototype satellites, the next three weeks of March are likely to be relatively quiet. However, by all appearances, SpaceX is preparing for a frenetic end-of-month that could include three Falcon 9 launches from three separate SpaceX launch pads, all in a single week, and as many as six launches total between March 29 and April 30.

When the cores are coming down they aim for a location next to the barge and only divert to on the barge at the last minute if everything is ok. This was going too fast, so no diversion.

(Less than) 24-hour bump for Iridium Next 5. I may have to come in to work a little early tomorrow to catch it.

No landing for either this or CRS-14, though. I understand why they're burning through their stockpile, but it doesn't make for very exciting webcasts.

DaFace 03-29-2018 09:18 PM

SpaceX won approval from the FCC for their satellite internet constellation.

https://www.cnbc.com/2018/03/29/fcc-...-services.html

If they do it, it'd be a minimum of 45 launches and up to 250 to get it going. Guess they're counting on this reusability thing to actually work because that's a **** ton of launches.

DaFace 03-30-2018 06:54 AM

Bump.

DaFace 03-30-2018 11:24 AM

Since this was clearly a highly exciting launch (/s), here are the only things that you really need to know:
  • Mission success. All 10 satellites deployed and operating properly.
  • No landing attempt for the first stage on this one. They're still clearing out old boosters it seems.
  • Still no success on catching the fairing. Apparently they're having trouble getting the parafoil guidance system to work right because the fairing itself is messing with the air flow. Still a work in progress.

DaFace 04-02-2018 11:58 AM

Dropped the ball on my usual 24-hour bump, but ISS-bound Dragon launches today at 4:30pm Eastern. No landing - they're still plowing through boosters apparently.

Yeah, they've been doing a bunch of weird stuff on the landings lately for these launches where they're dumping the booster. Probably not much that's exciting for us laymen - just seeing how far they can push the limits and still keep things in control.

Interesting, I'd seen it got approval but hadn't seen details. Fiber speeds sounds pretty crazy for satellite. Then again, fiber speeds doesn't really define much. If you're in the boonies, it's almost assuredly better than DSL though.

It was miles away from us but when the sound finally reached us it was like a subwoofer in my ear with the bass to the max.

24-hour bump for TESS. The launches are becoming a bit mundane, but this is the coolest payload SpaceX has ever launched. Assuming the mission goes well, you'll hear about the exoplanet discoveries being made with TESS for years. Here's a brief overview video:
