Talk:Cygnus (spacecraft)

December 2008

Stats anyone? Need some details on the craft's capabilities (cargo space, thrusters, launch vehicle, etc). Usarian (talk) 16:39, 26 December 2008 (UTC)

• Done. PistolPete037 (talk) 03:08, 28 December 2008 (UTC)

Spacecraft dimensions?

Does anyone have a source for the dimensions of the spacecraft? N2e (talk) 20:47, 31 January 2010 (UTC)

Relationship with Thales Alenia Space?

In the introduction, the article indicates that the spaceship is a collaboration between Orbital and Thales Alenia. In the main body of the article, the relationship is not clarified and only refers to Orbital. Is Orbital the lead partner in a consortium? Is Thales Alenia a subcontractor? Did Orbital win the competition and then subcontract or did a consortium including Orbital and Thales Alenia win the competition to build the ship? thanks. --mgaved (talk) 20:19, 3 April 2011 (UTC)

Orbital is main, Thals Alenia is a sub. NASA only has a Space Act Agreement with Orbital.--Craigboy (talk) 03:52, 30 March 2012 (UTC)

Descriptions of other similar vehicles

As the Cygnus is being developed, comparison to similar vehicles should either be a comparison to those likewise in development or mention the comparison is being made to developed vehicles. The simple omission of the word 'being' as in developed or being developed is not clear enough on this.Penyulap (talk) 14:12, 4 May 2011 (UTC)

"So will future full-up Cygnus vehicles, which will be outfitted to support both the cargo they carry for the space station and any hosted payloads Orbital can find. The company already has a contract with NASA’s Glenn Research Center to conduct a combustion experiment on an emptied Cygnus once Orbital begins flying out its $1.9 billion, eight-mission Commercial Resupply Services (CRS) contract. “We expect we will have a pretty sophisticated spacecraft that can operate on orbit for upward of a year,” said Michael Hamel, Orbital’s senior vice president for corporate strategy and development. The Glenn experiment will study how fires can propagate and be extinguished in a spacecraft, on a scale that would be unsafe to attempt on an occupied vehicle."

@32:00 - Typical mission will be about 30 days, including the rendezvous, the time aboard station, the time to de-orbit. We could extend that to 60 or 90 at NASA’s request, however once we separate from the space station, the spacecraft itself, depending on its fuel load could probably fly easily for another year, in terms of what the components are certified for.
@33:00 – They also believe it will be useful beyond low earth orbit.
@35:00 - Late june/Early July for COTS mission. History: The initial Antares flight was originally planned to launch Cygnys to the ISS, agree was modified to do test flight. They didn’t do it initially to save money (they received $100 million less than SpaceX).
@38:00 – Some good info on COTS

Solar arrays on standard variant are fixed (i.e. they don't move after they're deployed). https://ac.arc.nasa.gov/p5uwr8gcebb/?launcher=false&fcsContent=true&pbMode=normal&archiveOffset=1620000 --Craigboy (talk) 05:19, 29 April 2014 (UTC)

The Cygnus uses IHI BT-4 engine fueled by MMH/N₂O₂, and a lot of mono-propellant MMH attitude control thrusters. Currently the page lists only the oxidizer under the heading "Propellant".

Thanks for the comment and two sources. Perhaps some editor will happen by here and update the article, with addition of appropriate reliable source citations.

However, keep in mind that this is Wikipedia and anyone can edit. So why not take a stab at writing that prose yourself, and adding a citation (or two, if neeeded) to support your statement. Ping me if you would like some help. Cheers. N2e (talk) 03:57, 20 September 2013 (UTC)

TAS-I still producing

Yesterday I saw several of the things through a window, and they worked until 8 in the evening, so there are a few here in Turin which will be ready soon.--Stone (talk) 09:19, 17 October 2013 (UTC)

Manned version of Cygnus?

This article mentions that Orbital is developing a manned version of Cygnus. Does anyone have details?

The linked article is incorrect.--Craigboy (talk) 05:18, 29 April 2014 (UTC)

Cost per launch

It would be interesting to have those numbers, since that was much of the point of developing commercial space transport. I see a $1.9B contract covering 8 launches; does that mean they are ~$238M/launch, or is there funding for base development there? -- Beland (talk) 17:30, 8 December 2014 (UTC)

Fix the list of missions?

First off the comment at the top of the list of missions is obsolete, it says that 2 launches are planned on Atlas but that was 2 years ago, and it ended up being 3. Second, it might be helpful to add a comment at the bottom of the table about the CRS2, which already has 6 (IIRC) guaranteed but not scheduled missions attached to it. Come to think of it, CRS2 isn't mentioned at all in the article? Greg (talk) 02:19, 20 June 2017 (UTC)

Absolutely. Feel free to make the necessary updates. — JFG ^talk 06:37, 20 June 2017 (UTC)

Name of spacecraft

The table implies that there's an astronaut included in the payload (e.g. G. David Low appears, at first glance, to be on the Cygnus Orb-D1 mission). Sure, it quickly becomes apparent that that's not the case if one follows the wl and sees that the astronaut is dead, but better to avoid the issue. Any comments on me moving the name into the Mission? I.e:

Cygnus spacecraft missions

#	Mission	Payload	Variant	Launch date	Rocket	Payload mass	Outcome	Ref.
1	Cygnus Orb-D1 G. David Low	Cygnus 1 Orbital Sciences COTS Demo Flight	Standard	18 September 2013	Antares 110	1,299 lb (589 kg)	Success
		First Cygnus mission, first mission to rendezvous with ISS, first mission to berth with ISS, second launch of Antares. The rendezvous between the new Cygnus cargo freighter and the International Space Station was delayed due to a computer data link problem, but the issue was resolved and berthing followed shortly thereafter.

How to treat the Cygnus Mass Simulator

In the article's Missions section, the table currently doesn't list the Cygnus Mass Simulator launched on the Antares A-ONE flight. However, as this flight was funded by NASA's Commercial Orbital Transportation Services, and is essentially a precursor to Cygnus, I suggest that the table also include the Cygnus Mass Simulator as Mission #0.

For example, Template:Cygnus spaceflights (shown below) contains not only the actual Cygnus missions, but the Mass Simulator mission as well.

NG-10

Why is there no E (NG-10E) in the name? Was it not an extended flight of CRS 1? Or was it the first flight of CRS 2? — Preceding unsigned comment added by 146.60.197.5 (talk) 12:00, 18 April 2019 (UTC)

Cygnus (spacecraft) → Northrop Grumman Cygnus – Consistent with SpaceX Dragon, Boeing Starliner, etc. articles. Soumya-8974 ^talk _contribs ^subpages 08:41, 20 July 2020 (UTC)—Relisting. —usernamekiran (talk) 21:33, 28 July 2020 (UTC)—Relisting. Jerm (talk) 03:48, 9 August 2020 (UTC) —Relisting. Megan Barris (Lets talk📧) 06:31, 17 August 2020 (UTC)

• Question Is it actually called that in reliable sources? From a quick look at Google news, it seems that while those other examples are regularly called those names, this one gets described as "Northrop Grumman's Cygnus" but not with the title Northrop Grumman Cygnus.--Yaksar (let's chat) 14:48, 21 July 2020 (UTC)

  Northrop Grumman's Cygnus is enough to verify that Northrop Grumman Cygnus has enough use in reliable sources. Cf SpaceX Dragon 2 and Boeing Starliner. --Soumya-8974 ^talk _contribs ^subpages 09:32, 25 July 2020 (UTC)

• I disagree. One is a description, the other is an actual title. It's the difference between Nintendo Switch and Sony's Playstation 4.--Yaksar (let's chat) 04:44, 3 August 2020 (UTC)

• Another question Just saw this but doesn't Wikipedia:SPACENAME say "We prefer not to include the name of the manufacturer or developer in the article title, unless necessary." and "Use "(spacecraft)" as a disambiguator for other spacecraft"?

Payload / Variant Disambiguation

The payload stated in the stats box of 2000kg to LEO is not correct for the currently flying variant. 3500kg buried in the text of the Development section.

There are also confusing references to +700kg pressurised cargo and "upgraded to carry 10 to 15% more pressurised cargo that the current CRS-1 Cygnus version." We are now into NG-14 in CRS Phase2, so this is not current.

NG-14's page states 3551kg payload, which is more than the max listed above. It does not match table line 15 for NG-14 on this page's Missions section which states 3458kg.

This page could use some clean up.82.108.2.131 (talk) 11:54, 5 October 2020 (UTC)

Premature success

The latest launch is listed as a "Success" when it hasn't docked yet, and has a solar array problem. Greg (talk) 20:42, 8 November 2022 (UTC)
