Reusable space plane

One piece of news noted by international press was the plans for CASC to trial a reusable space plane by 2020.

Very few details are public, but the first step looks to involve a two-stage to orbit, rocket-powered vehicle that can take-off and land horizontally.

A single-stage-to-orbit version with combined cycle propulsion is the goal for 2030, which would be capable of carrying cargo and crew to low Earth orbit with a one-day turnaround on the ground, greatly reducing costs.

The hybrid space plane would use a combination of turbojet, ramjet and scramjet technology to reach hypersonic speeds in near space, before using rocket engines above the Karman line (100 km altitude).
for a brief second, I thought this is what they meant with "sea launch"...

some super rocket like the Sea Dragon

according to this
https://www.theverge.com/2018/1/9/16...alcon-9-rocket

suspicion began when space x did not make any statements on a successful launch.

secondly reports from WSJ that lawmakers and government people were informed of its demise

But theres some disagreement over where it was lost.

https://www.space.com/39328-spacex-s...statement.html

Quote:
"For clarity: after review of all data to date, Falcon 9 did everything correctly on Sunday night," SpaceX President and Chief Operating Officer 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," Shotwell continued. "Due to the classified nature of the payload, no further comment is possible."
Quote:
Berger noted that the payload adapter connecting the stage to the payload and fairing was provided by Northrop Grumman, so a potential separation problem could track back to that company's failure. A Northrop Grumman representative told Space.com the company cannot comment on classified missions

there is no fingerpointing.

the US government has all the telemetry data of the Falcon launch. SpaceX could not lie about it. Telemetry data shows the Falcon 9 worked properly.

Also, it's KNOWN Northrop Grumman made the fairing coupling mechanism. Actually, it seems SpaceX was not even responsible for puting Zuma inside the fairing!!

From comments on Space.com article

Quote:
Back in either Nov or Dec, shortly after the Zuma mission was made public, an article appeared on one of the SpaceX tracking sites that said the Zuma mission was so secret that Zuma was encapsulated within the fairing in a separate facility by non SpaceX personel. Failure of satellites to detach from the 2nd (or 3rd) stage after reaching orbit has doomed many satellites in the past. This appears to be the case in this instance.

That secretiveness may also doom efforts to find the root cause of this failure. In most if not all SpaceX launches, cameras ride the fairing bus so that views are available real time to see that the fairing has separated properly and that the satellite(s) have deployed. One woud hope that sort of video is available to the investigators (although we may never see it).
Quote:
The Falcon 9 first and second stages did exactly what they were supposed to do. It would be stupid for Spacex to lie about that since the government had access to all of the Falcon 9's telemetry data as it was happening (ruling out falsification of the data after the fact). So it has to come down to the payload release mechanism. This was one of the few launches where the customer provided that mechanism rather than using Spacex's version (which has a perfect record), so it would be a weird coincidence if the payload release issue was somehow Spacex's fault.

Also, Spacex has stated that their rocket behaved nominally, whereas Northrop Grumman is basically saying "no comment". Classified or not, I seriously doubt that NG wouldn't take the opportunity to defend the performance of their hardware if the data suggested it had behaved nominally.

And finally, Spacex has not delayed preparation for Falcon Heavy or other launches on their manifest, as they would likely be doing if there was any evidence of a flaw in their Falcon 9 rocket (Falcon Heavy is basically made up of three Falcon 9s strapped together). In fact, they'd probably be required by the powers that be to halt those operations.

So I feel pretty confident that Spacex is in the clear on this one. Of course, you wouldn't know it by most of the headlines in the mainstream media over the last 24 hours or so.


another guy there said EXACTLY what I think
Quote:
I don't believe there is any problem with the payload and it is exactly where the owner wanted it. They want everyone else to believe it was lost. "Secret Payload".
Think about it.
SpaceX launch was 'nominal'.
Publicly, no one knows where the payload is.
It completed one orbit, hence the number was assigned.
We don't know the purpose of the payload, so we wont know if it is working.
The launch couldn't be hidden, but now the location is unknown.
Hmmm....

Not that my experience with rocket payloads extends beyond Kerbal Space Program, but the second stage appears to have deorbited exactly where it was supposed to (deorbit burn somewhere over Africa, burnt up in the atmosphere east of Madagascar). Would it have been able to do that with the payload still attached to it? One would assume that the extra mass would have screwed up the deorbit burn.

more than that... if the payload was still attached, wouldn´t they ask SpaceX to keep the 2nd stage orbiting for a few more orbits while they tried to solve the problem?

Piece of filth article written on the Federalist website about SpaceX, posting here for us to ridicule it now and in the years to come:

Quote:
Why SpaceX Is The Snake Oil Peddler Of The Twenty-First Century


Worrisome national security events have convinced some Americans that SpaceX is the magic elixir of this generation. But this time our national security is at stake.

Beau Rothschild By Beau Rothschild

JANUARY 16, 2018

In the nineteenth century, Americans across the country were mesmerized by “miracle elixirs,” better known as medicine shows, which offered “cure-alls” for everything in the book. Diseases? There was a drink for that. Wrinkles? There was a magic cream for that too. These traveling shows did far more than “heal,” they entertained. Freak shows, magic tricks, and storytelling, among other fun activities, were included on the lists of offerings.

For many, these flamboyant events were awe-inspiring – that is, until the country realized these “miracle cures” were almost completely ineffective. Over time, an increasing number of Americans began referring to these big promisers as “snake oil salesmen.” By the next century, most disappeared, as did their outrageous claims.


Worrisome national security events that transpired this week have convinced some Americans that SpaceX, a rocket manufacturer and launcher for national security missions, is the magic elixir of this generation — only this time, the “magic pills” in question are not only often ineffective, they’re also affecting the country’s national security.

Akin to the once-beloved nineteenth-century miracle workers, SpaceX often tries to entertain onlookers with flashy proclamations. It has pledged nearly unfeasible feats, such as sending humans beyond the Moon by the end of the year and potentially landing spaceships on Mars by 2022 — both of which will allegedly occur on rockets that have either failed to get off the ground or have had trouble doing so. It is not without a sense of irony that the CEO of SpaceX suggested those few who decide to go to Mars may not live to tell about it.

It is hard to criticize SpaceX’s public relations strategy. After all, it is competing against some of America’s most prominent companies, so drumming up eye-popping media coverage is a must. But past and possible present operational concerns have led some to seriously question the company.

SpaceX attempted to launch a billion-dollar classified government satellite on Sunday, coined “Zuma,” for an unknown government agency. No one knows if it succeeded, but many have
expressed skepticism, citing possible errors on SpaceX’s end.

Not really. They are delivering what they're being paid for, which is the exact opposite of the snake oil salesman.
