Anyone have info on the spy satellite that SpaceX failed to launch, but blew up???

Think SpaceX just lost lots of gov funding...cuz think the gov won't be using them much anymore after losing a multi hundred million bucks satellite...


Spacex and Northrop Grumman are busy pointing fingers. The satellite failed to separate from the upper stage of the rocket. The question is why? I can only add this launch was delayed 3 times while Spacex evaluated data concerning the fairing covering the payload, and possible issues with it being successfully jettisoned once out of Earth's atmosphere. This info was widely reported here, maybe not so much in the national media. Failure of the fairing to jettison could be a factor that Elon doesn't want to discuss. FWIW, this launch was also the first from the Canaveral AF Station pad that was severely damaged by a Falcon 9 explosion during a ground test in 2016.

You’re welcome Ben,
Here’s the Aviation Week piece on it.

CAPE CANAVERAL - SpaceX said the Jan. 7 launch of the classified Zuma mission appeared to have been successful, but questions about the spacecraft’s health surfaced the following day.

Amateur satellite watchers spotted the rocket’s upper stage venting propellant over East Africa about 2 hr. and 15 min. after launch, suggesting Zuma might be in a 900-1,000 km high orbit, according to a post on SeeSat-L, an internet mailing list for visual satellite observers.

“It is impossible to estimate when it might be spotted. It could happen within a few days, but could easily take weeks or months,” Ted Molczan, a longtime satellite observer who administers the mailing list, wrote in an email to Aerospace DAILY. "Satellites have been known to fail spectacularly … but I suspect that Zuma is alive and well."

As of Jan. 8, Zuma was logged in the international registry of satellites, though it “remains to be seen if that is a mistake,” said Harvard University astrophysicist Jonathan McDowell, author of Jonathan’s Space Report newsletter. “My hypothesis is that Zuma did not separate from [the upper stage] and both stayed in orbit long enough to get a catalog number, but then was de-orbited. [It’s] still very unclear." The catalog listing provided no orbital details or re-entry information, both of which may have been withheld due to the classified nature of the mission.

However, other reports, citing anonymous intelligence and industry sources, say the spacecraft, built by Northrop Grumman for an undisclosed U.S. government customer, failed to separate from the Falcon 9’s second stage and did not reach orbit. Northrop hired SpaceX for the launch, which occurred at 8 p.m. EST on Jan. 7 from Cape Canaveral Air Force Station, Florida.

"After review of all data to date, Falcon 9 did everything correctly on Sunday night," SpaceX President Gwynne Shotwell said in a statement. "If we or others find otherwise based on further review, we will report it immediately. Information published that is contrary to this statement is categorically false. Due to the classified nature of the payload, no further comment is possible.

“Since the data reviewed so far indicates that no design, operational or other changes are needed, we do not anticipate any impact on the upcoming launch schedule," Shotwell continued. "Falcon Heavy has been rolled out to launchpad LC-39A for a static fire later this week, to be followed shortly thereafter by its maiden flight. We are also preparing for an F9 launch for SES and the Luxembourg Government from SLC-40 in three weeks."

“This is a classified mission. We cannot comment on classified missions,” Northrop spokesman Lon Rains said.

What does all of this mean? It's unclear. But Grush writes that SpaceX appears to be trying hard to communicate that it did everything right, without excluding the possibility that there was a failure once things entered Northrop's sphere of responsibility. It's certainly possible that SpaceX's Falcon 9 successfully lofted Zuma to orbit, but that Zuma failed to deploy or operate properly after deployment.

It might become clearer in the coming weeks whether a new satellite now orbits the Earth, alive or dead, as amateur astronomers try to spot the object. Already, one such early datapoint has come in: Peter Horstink, the Dutch pilot of a Boeing 747-400 freighter flying at 35,000 feet (about 10,700 meters) just north of Khartoum, Sudan, photographed a green-blue "spiral" that, according to SatTrackCam Leiden's blog, was likely the result of the Falcon 9 upper stage depressurizing and venting fuel.

He is appealing to extremes by passing off an extreme or rare scenario as a normal one. Logical arguments don't do this, but when you are bias towards something then sometimes logic goes out the window and you only see what you want to see good or bad depending which way your bias feels about the topic.
OK did the dirty battery/EV calculation consider Tesla factory is powered entirely by solar?
While IC is built with coal fired electricity.

Like to see one of those battery factories on fire...

Florida Today (local Brevard County paper) reports SpaceX is scheduling static fire test of the Falcon 9 Heavy next Wednesday. Elon Musk is tweeting if all goes well the Falcon 9 (and Tesla Roadster payload) will launch at the end of the month.

Apparently GM is spending huge amounts of $$ on new battery tech. That's money they make from people buying big trucks with their high profit margins. [emoticon]

One of their main research avenues is reducing the amount of cobalt in their batteries.

A key element of the plan, according to two people familiar with the company's strategy, is slashing the amount of cobalt in GM's new EMC 1.0 battery system. The price of cobalt — the single most costly ingredient in current lithium-ion battery cells — has soared in the past two years in expectation of a surge in demand from automakers. Cobalt prices hit a record high this month on the London Metal Exchange.

GM's new battery design increases the amount of nickel, which enables batteries to store and produce more energy, these people told Reuters.

My bet is that it will be the first to market share and will become the defacto standard for a while until science/technology catches up

Another bet is that the quick change/charge will take this market share. China has an electric start up that has a standardized battery pack that they say can be changed out in minutes. Read of another China based startup that is working closely and is a mobile truck/van that can come to change your battery pack...AKA road side service & that 5 gallons of fuel we are used to with ICE's...but this will be full charged battery pack

Key there will be 'standardized' form factor and/or volume

Since standardized form factor...doesn't really matter what battery IP will be adopted. As long as it has the KW's and minutes to change out to a fresh battery...it will kill any EV with a built in that takes hours to charge

Can be good old NmH or lead acid or even Lith-Ion for now and wait for battery tech to catch up to this wide open market...my bet that is

Battery IP is out there, but the hurdles are many. Mainly money at this point with IP a close second

Latest on solar panels...they are jumping for joy that one company has broken the 17% line and is boosting of a +19% solar panel. There is significant head room on this, but the industry standard is +20 year life span/warranty on solar panels. This +19% solar panel is said to have a 25 year warranty.

Although I would kind of like to see the exchangeable battery develop I'm not sure in the near term (a decade or two) that it will happen. Both of our vehicles are EV's so we are fairly in tune with what the various manufacturers are doing. Many of us driving EV's still find it amazing that there are still three standards for DC fast charging in North America and five if you include Asia and Europe. We don't use DC fast charging much but one has to be on the ball and hope the phone apps are up to date on what point has what standard.

At least everyone seems to have settled into J1772 standard for level two AC charging. But even with J1772 we need to use an adapter to charge at a Tesla Level 2 charger and vice versa for them. It would be nice if everyone could get together on this front. Right now Tesla is boss hog with the SUpercharger network and is one of big reasons we will consider them for our next vehicle. Love our leaf though. Best car we have ever owned.

Solar panels are interesting thing. The capacity they do lose is in the first decade and then they kind of level out. It would be interesting to see what todays panels are still putting out in 75 years or so. Some speculate at more than 50 percent depending how scratched up the surface is. Interesting.
