Dragon CRS1, Orbcomm 2G=Falcon 9 v1.0 - Canaveral SLC-40 - 08.10.12 00:35 UTC

[К.А.]

Кстати летит новый КК или он уже летал.

[Salo]

Думаете покрасили?

[К.А.]

Но ведь корабль многоразовый или пока нет?

[Salo]

Пока нет. Иначе пиар уже зашкаливал бы.

There's a pre-launch presser at 6pm Eastern on NASA TV if someone wants to cover it. (I can't).

Suff. talking about hardware they wanted to fly on ATV, they are instead flying on CRS-1. Talked about how it was easier to fly thanks to domestic capability.

Shotwell going over the timeline for this flight. Opportunity for Monday and Tuesday if scrubbed due to weather. Berthed by JAXA astronaut and Suni Williams. 1000 pounds of cargo up, including powered cargo (Glacier freezer). bringing back Glacier as well. Insertion orbit slightly different on this mission compared to COTS2. Full cargo racks. Volume relatively full. Falcon 9 is the same. FTS improved, minor differences.

Weather officer: Weather currently not favorable, optimistic it'll get better tomorrow. even less chance of weather violation on Tuesday.

sdsds пишет:

Marcia Dunn asks about the low mass of cargo up. Shotwell dodged the question.

EDIT: On followup fr om another reporter, Shotwell: "I don't think there is any chance we won't make our 20 mt target."

tigerade пишет:

Could you put on more to go up on the Dragon? (cargo)

Shotwell: CRS2 - scheduled for January
it's about volume
required to fly 20 metric tons, will carry 60 metric tons on successive flights

What if failure?

Shotwell: If mission failure, won't be fully paid. I don't believe there is any chance we won't reach 20 metric ton requirement.

What's the most important thing learned from COTS2?

Shotwell: Spaceflight continues to be difficult, lot of hardwork went into that mission. Not easy, hopefully we get better and better. It's a good reminder that this is hard.

Dragon will be on station for about 3 weeks.

Anything special on board Dragon?

Suff: Flying things up for whole team. Don't know really, talked about ice cream. (light hearted). Bonus food.

Secondary payload?

Shotwell: Secondary payload... Orbcomm sat. Needs to operate on orbit before launching 8-12 of them on a single flight.

Instantaneous launch window?

Shotwell: Not instant, but pretty dang close. Want to rendezvous with ISS. Short window for that. Could not recycle in time. That's why it's instantaneous.
Suff: True for all vehicles, including Soyuz.

Weather constraints?

Shotwell: Could have vehicle on pad during the rain. Has to be vehicle on pad for 1pm. Late load cargo. Ice cream possible.

Further ahead in Texas, possible commercial site in Brownsville. Puerto Rico nice. Georgia potentially. Further along with Texas.

COTS2 comparison?

Shotwell: Won't do C2 maneuvers. already demonstrated. Will just go to station this time.

Suff. on space debris: Possible on Monday, probably will clear. will talk to spacex if ISS is maneuvered. I think will turn green.

Suff: Tests still going on with Orbital Sciences. Not expecting demo flight until late Feb/early March.

Human spacelight on Dragon?

Working closely with all 3 companies on space act agreements.

How much of hardware is built in California?

Shotwell: Vast majority of hardware built in California. Build tanks, domes, engines, avoinics, build Dragon, merlin, draco. Would be easier to tell you what we don't build.

Suff: SpaceX can maneuver if ISS is maneuvered for debris.

Cabana talking about changes to the Cape.

Anything from Russia segment for return cargo?
Suff: Yes. Has arranged with partners. As need arises.

Plan to do own launches in the future?
Shotwell: Will do own technology development, doesn't do science. Moon and Mars are very ambitious, would be very difficult to do on our own. Want to be part of partnership.

Space tourism for Dragon?
Shotwell: Designed for humans, just not capable yet. Working on it. Biggest thing is LES. Still crew interface work to do, space suits. We are working on it. Market not well defined outside of NASA. Tourism? Not a focus, but thrilled about it.

How far is crew rating?
Shotwell: Will fly crew in 3 years probably. 7 astronauts possible on Dragon.

And that's a rap. Good talk.

Question asked about the status of the future launch site being considered about SpaceX, specifically in relation to the one in Texas. They're considering many launch sites, but are the furthest in negotiations for the Texas one. A site north of the cape and one in Georgia are also being considered.

northanger пишет:

Shotwell: We are driving straight to the station. C2/C3 demonstrated we could.

How much is built in California?

Shotwell: SpaceX is not an integrator of other companies, we build a vast majority at SpaceX... probably easier to say what I don't build there.

Suffy just said: We are going to launch on Sunday, the good Lord willing.

Cabana: During these times of inflation, &c, we're tightening our belts as needed to make sure (if we can't do all we want) that we continue to do what needs to be done.

Someone just asked again, which ice cream? Suffy: I don't even know if we're flying ice cream.

"We have to take care of Suni", somebody else says.

Another question, prior: Sarah Brightman flying Soyuz, is SpaceX planning on tourism?

Shotwell: We desgined Dragon with crew in mind, doesn't mean it's capable now, but it's got the "hooks".... there's still some crew development that we have to do... but we're enhancing Dragon to handle crew. Space tourism is very ill-defined right now, [Bigelow mentioned]... I'm thrilled to hear about anyone buying a ticket, but tourism is not a SpaceX focus right now.

These are some of my notes:

Instantenous launch window, why?

Shotwell: Not exactly, but close. Those windows tend not to be long... we could not recycle in time so in effect [grammar check] it's fundamentally instantaneous.

Suffy pointed out that launch is a precise point wh ere it's most efficient... shuttle had a whole ten minute window ... we want to conserve performance and launch at the best time. This is true for all spacecraft launching to ISS.

Sam and Shotwell both (at different times) expressed that space was not easy or routine. Shotwell pointed out it's about improving performance ability which they're working toward. This mission should "go a little bit smoother"... SpaceX has developed a great relationship with NASA, the Air Force, FAA, and the FCC has been helpful this time round.

If they fly Sunday, it's 53 hours before rendezvous and berthing, opportunity the same on Monday. Tuesday it's 30 hours.

add:
This is the first time SpaceX sends GLACIER up and brings one back. Suffy talked a little more, later, about different items they could start to bring up and down.

I certainly meant no disrespect for Shotwell. To the contrary she does her job excellently well!

In this case the question was essentially, "Couldn't you have carried more up mass on this flight?" And the answer she avoided giving was, "No, for this flight we really couldn't do that while maintaining the margins we want."

Instead of giving that answer she essentially gave us, "No problem getting to 20 tons up mass over the twelve flights," and as a distraction threw in, "Expecting 60 tons combined up and down mass total."

(Of course they will achieve all that, but not using Falcon and Dragon vehicles exactly like those used for this flight.)

Но ведь корабль многоразовый или пока нет?

Он многоразовый, но заказчик просит каждый раз новый. Кто платит, тот и заказывает музыку. В принципе есть идея использовать отлетавшие Драгоны под DragonLab, чего добру пропадать. Может быть со временем их доработают под Биглоу, или NASA согласится на переиспользование. Или просто спишут как безнадежно устаревшие.

NASA уже сообщила, что SpaceX может использовать "использованные" Драконы любым образом.
Судя по летавшим девайсам, многоразовости там больше чем в Союзе (тема ГВК), но меньше чем в проекте ПТК-НП (в части ВА)

[К.А.]

Всем спасибо, прояснили обстановку.

Повторные полеты можно проводить с туристами. Просто цена билета с каждым полетом будет немного падать. :wink:

После третьего  - перестанут страховать, после пятого - начнут приплачивать туристам :wink:

Кстати Orbcomm 2G похоже останется на опорной орбите.

[SpaceR]

Кстати Orbcomm 2G похоже останется на опорной орбите.

Почему? Думаете, топлива слишком мало для restart движка?
Или где-то записано?

[Salo]

В пресските нет ни слова о втором включении. Поглядим.

Пресс-кит посвящён миссии CRS-1 для Дрэгона, возможно попутки её не особо волнуют.

Когда вопрос о малой массе ПН задали Шотвел, она не стала ссылаться на довыведение Orbcomm.

Во втором полёте к МКС мы видим около 453 кг вверх и 905 кг вниз в герметичном объёме и ещё 142 кг попутной нагрузки в виде Orbcomm 2G.
Итого масса ПН:
4200+1227+681+142 = 6250 кг

Согласно NLS2 ПН F9 v1.0:



Где ещё 2 тонны?

[Bizonich]

Какое второе включение, старт сегодня ночью.

[Александр Репной]

Извиняюсь, если это где-то было уже в теме. Когда планируется стыковка Dragon с МКС, если завтра утром улетит Falcon 9?
