Delta IV rocket launch with secret US satellite canceled

The United States was unable to launch a secret satellite into orbit. The launch of the heavy launch vehicle Delta IV was canceled three seconds before the launch. The operator United Launch Alliance (ULA) reported.

According to the company, the launch of a heavy launch vehicle Delta IV with the US secret NROL-44 satellite of the US National Aerospace Intelligence Agency (NRO) was canceled for technical reasons, and fuel was drained.

They tried to launch the rocket at 02:28 US East Coast time (10:28 Moscow time), postponing the initial launch time by more than an hour. The reason for this was the drop in temperature in one of the rocket compartments after liquid hydrogen was pumped into the tanks. However, despite all the preparations, three seconds before the start, it was decided to cancel the launch, postponing it to another date, which will be determined later.

The rocket was supposed to launch a secret satellite NROL-44 into orbit, the characteristics of which are classified. However, there is information that the Orion spacecraft, a satellite from a series of electronic reconnaissance vehicles, was to be launched as part of the NRO program. The main task of this 5-ton satellite is to intercept telemetry information and listen to communication channels of geostationary satellites.

There are currently seven similar satellites in orbit, launched from 1995 to the present. The device was developed in conjunction with the CIA.

Secret satellite NROL-44 And what a secret it is, if its abbreviation is already known, it means that something else is known about it.

[Blackmokona]

NROL is just a stub, for example NORAD writes all secret USA number.
NROL "National Intelligence Agency launch" If literally

[ltc35]

They would call all the satellites simply, as in the USSR, "Cosmos -..." and not soared. And let the partners delve into conjectures!

[Guillon]

What partners? !!

[ltc35]

I don’t understand which ones. But GDP calls them that. Do you really want to argue with Himself? !!

Presumably, this is Orion 10 (Mentor 8), which will be fixed in the equatorial plane in a geosynchronous orbit. There is the interception of telemetry of missiles of the Russian Federation and the PRC, and the removal of intelligence from other people's measuring devices (FISINT), and - what may now be a priority - the interception of communication channels between people (COMINT).
These satellites are (presumably) equipped with a main antenna with dimensions of over 100 m when deployed and weighing over five tons. The customer is the US National Intelligence Agency, the existence of which was officially denied by the authorities until the 1990s. The cost of the device, according to various estimates, is from $ 1 billion and more.

[Vadim237]

It is also known that this satellite has a 100 meter antenna.

[Thrifty]

It was necessary to launch it anyway, and it didn't matter that the satellite would not go into orbit, or the launch vehicle exploded at the start! !!! Rogozin is not present for NASA

oxygen hydrogen vapor is not toxic, if you have attended grade 7, you should know. Any hydrogen leak is a big bad-boom (c) 5 element ... this bond gives the maximum range for the formation of an explosive mixture (oxyhydrogen gas). EMPIP from 4,5% to 7x (more accurately, you can google)

And what does the toxicity of hydrogen have to do with it？ Perhaps the comrade meant the literal meaning of the word dirtiest, in the sense of fright.

[vVvAD]

Well: the launch has been postponed, the unfriendly plans of the United States are shifting and becoming more expensive, which is not bad.
There will be additional tests and opportunities for our agents to learn more about him

Yes .... hydrogen has a specific impulse ... but how much hemorrhoids it has with it, starting with blowing the hoses when refueling, and cooling, ending with its leakage in long missions. Hydrogen hates us ...

All right.
This is why Musk ALWAYS declared "hydrogen shit".
This is one of the "secrets" of Falcon 9's success - no hydrogen and no solid fuel boosters
- everything is simple and monotonous with one type of inexpensive but efficient engine on both stages.

[Split]

And we don't really like him either. Offhand, the 2nd stage of Energy-Buran (RD 120 or 0120 emnip) and that, in fact, is, in my opinion, the first engine that took off - but I could be wrong. How would not like to get rid of heptyl-amyl.
Therefore, the news about the hydrogen-oxygen hangar, when even the usual one cannot really be ... no comment

I hasten to reassure you - there will be no crazy hydrogen-oxygen hangar. To begin with, the funding for it has already been cut. Then I hope the mind is enough to focus on the correct methane in the new rockets.

Not. No funding was cut for the production of new media.

Manufacturing of the RD-0177 demonstrator engine has begun. A competition for an LNG carrier will take place in the near future.

Trump received a secret order from Putin to cancel the launch of a secret American satellite. But this is all, as you know, a secret, as well as an overdose in the body of black life, which is of such great importance.

I don’t believe in satellites since 95 LIVE. The normal lifetime of satellites is about 7 years. If specially the supply of fuel for the correction can be more, and still live. But not 20 years. And in geostationary orbits, radiation is also trying, damaging electronics, even radiation-resistant ones, damage accumulates over time, to critical.

[donavi49]

Here is the 2006 satellite launched by the peaceful Topol (Start) for Israel. 14 years old and everything works

As for geostationary ones, there has long been an emphasis not on dead electronics, but on fuel. For example, Arabsat6a, due to a more powerful launch vehicle than Arian, was able to significantly save its fuel on the way to the target orbit, and this extended the fuel life by 4-4,5 years = up to 19-20 years, according to the calculations of the operator of this satellite.

Also, the topic of space tractors is now actively promoted. There are already 3 different companies working in prototypes + launch contracts. And MEV from Northrop has already reached the Intelsat 901 satellite - produced in 2001, pulled it into the target orbit and will keep it there until 2025, and then it will be pulled into the cemetery. The second one is flying now for Intelsat-10-02 - it will extend its life by 6-7 years.

Such a tractor will dock with an exhausted satellite and maintain its orbit. There will already be an emphasis on functionality, and 30-40 years of operation does not seem fantastic.

[Mountain shooter]

I wrote about satellites launched in 95. The guaranteed service life of modern satellites in geostationary orbits is 15 years. Some are more fortunate. And all the same. For a perfectly legitimate doubt about 25 years of old satellites - such a rebuke? For what?

[donavi49]

I just pointed out that the satellites of the early 00s (Intelsat 901) fly out on fuel and new technologies give them +5 years of life. And in general, for new platforms + a tractor - 30-40 years is already a reality (for satellites launched now 100%, for satellites 10-x 50/50).

The satellites of the 90s are still weaker on the platform. However, it is quite possible that they still work in some format.

If anything, the article most likely meant that this program has been running since 95.

[nickname7]

The typical lifetime of satellites is about 7 years.

These are Western satellites for 7 years, and Russian satellites live for 3 years, due to the lack of joy-resistant electronics.

Their lifespan is just over 20 years. But in any case, launched in 1995 is unlikely to work. The last series (starting with Orion-5) has been launched since 2003. So the last episode is most likely workable

fantastic news! I apologize for not being in the subject !!
-Turkey has publicly announced the purchase of Su-35 fighters.

Turkey intends to purchase 40 Russian Su-35 fighters. This was stated by Turkish media with reference to a source in the Turkish Defense Ministry. According to some reports, the contract between Russia and Turkey was concluded within the framework of the Army-2020 forum, while the talk could be about a deal worth about 3-4 billion dollars.

“After purchasing the S-400, Turkey will take another step towards the contract for the Russian Su-35 fighters. And, with a very high probability, he will buy them. And the United States, it seems, will wipe out exactly as it did after the delivery of the Triumph air defense system. Ankara has already chosen a strategy against possible US sanctions. Will 40 "dryers" be enough to gain air supremacy in battles with the air forces of Greece and Egypt? If you compare in quantity, then no: even the Greeks have 156 F-16 Fighting Falcon (Fighting Falcon), as well as 22 Mirage 2000. If you add another 200 Egyptian F-16, then the balance of power leaves no chance at all for the "Turkish" Su-35 ... Of course, the outcome of air battles is influenced not only by the number of aircraft and not even by the training of the pilots, although these factors should not be underestimated, ”the Svobodnaya Pressa newspaper quotes the information with reference to the Turkish edition of Milli Gazete.

Considering the number of Su-35 fighters being purchased by Turkey, it is likely that Russia will provide a loan for Ankara.

This "special" is called automatic start-up. In this particular case, the automatics identified the problem with the ground and stopped the launch.

It is interesting how more than 3 dozen Orions can be found when 9 of them were launched, incl. 7 after 1995?
