Episode 49 features Kathy Lueders, Manager of the Commercial Crew Program based at the Kennedy Space Center in Florida, and discussions of a brief history of the space program, how it started, and where it is now.  Lueders talks about the two commercial companies, Boeing and SpaceX, and their space vehicles that will carry astronauts into low Earth orbit. This podcast was recorded on Wednesday, May 30th, 2018.

[Apollo13]

Host:  And so that's what actually got us to where we are kind of today where there's two companies getting ready to fly American astronauts again. 

Kathy Lueders:  Two companies.  They have their-- spacecraft is really, really cool right now.  I can't tell you-- go out to SpaceX, you see spacecraft in the building, one-- our DM1 vehicle's getting ready to roll out to go to Plum Brook in a week and a half.  You go over into the C3PF down in Florida and the Boeing spacecraft, you get C3 spacecraft, the Spacecraft 1's getting ready to get shipped out to go support pad abort test.  Spacecraft 2's getting ready to get shipped to California to go through environmental testing and that will eventually come back and become our first crewed flight test vehicle.  And Spacecraft 3 is getting assembled and will be getting ready to fly later this year.  So, it's-- we have-- it's really, really cool.  We have six spacecraft in different stages of construction and really final integration and testing right now to support all the critical system-level tests, but also for the demonstration test. 

[Apollo13]

Host:  Gotcha.  Well, back to CST-100.  So, four seats?  Four people launching inside the capsule? 

Kathy Lueders:  So, they actually have-- they have more capability.  They actually have proposed a fifth seat, so we have a fifth seat capability.  We right now are focused on kind of optimizing it for our mission, which is the four seat and the cargo for that, but they actually proposed a fifth seat.  And then the SpaceX, we're working a four-seat with all our cargo complement, but they actually also advertised seven, commercially.  So, it's always-- you can go-- what's really cool, you can go on websites and see what commercially they're offering and then we can, you know, we've kind of optimized for our mission certain cargo complements, certain crew complements that kind of support the station mission.

Crew Dragon is at @NASA's Plum Brook Station testing facility in Ohio, home to the largest thermal vacuum chamber in the world, to demonstrate its capability to withstand the extreme temperatures and vacuum of space.

Получается Дракон на много месяцев впереди Старлайнера?

Там ничего непонятно. Они очень разными путями идут. Ходят слухи, что будет хорошо, если в этом году состоится хотя бы один беспилотный пуск и не понятно будет это Дракон или Старлайнер.

[Чебурашка]

Ну так любой новый корабль должен через эту вакумную камеру пройти.
На конец года или на начало 2019, насколько я знаю, в этой камере должен оказаться Орион в полной сборке.

Смешно
Всем здравомыслящим это понятно и без всяких слухов.

Hardware Put to the Test

SpaceX's Crew Dragon is at NASA's Plum Brook Station in Ohio, ready to undergo testing in the Reverberant Acoustic Test Facility—the world's largest thermal vacuum chamber. The chamber will allow SpaceX and NASA to verify Crew Dragon's ability to withstand the extreme temperatures and vacuum of space. This is the spacecraft that SpaceX will fly during its Demonstration Mission 1 flight test under NASA's Commercial Crew Transportation Capability contract with the goal of returning human spaceflight launch capabilities to the U.S.

[SIZE=8]SpaceX's Crew Dragon spaceship marches towards launch with vacuum chamber test[/SIZE]

By Eric Ralph
Posted on June 20, 2018

SpaceX has published the latest photo of its next-generation Crew Dragon spacecraft, showing the crewed vehicle preparing to be put through its paces inside a NASA thermal vacuum chamber located in Cleveland, Ohio. If the tests are completed without issue, the Dragon's next destination will be Cape Canaveral, Florida, where it will prepare for an inaugural launch targeted for the fourth quarter of 2018.

In the photo released on June 20th, SpaceX's DM-1 Crew Dragon capsule (C202 in shorthand: [C]apsule, Dragon [2], serial number [02]) is seen being craned by SpaceX technicians into the thermal vacuum chamber at NASA's Plum Brook testing facilities. Located in Ohio, Plum Brook's vacuum chamber is unique because of both its size and its ability to fairly accurate replicate the actual environment faced by satellites and spacecraft once in space. Most importantly, this includes the extreme thermal conditions those vehicles are subjected to by constant ~90-minute day-night cycles in low Earth orbit (LEO).

Without Earth's cozy atmosphere to act as both a heat sink and insulating blanket once on orbit, there is simply nothing there to protect spacecraft like Crew Dragon from the absolute extremes of direct solar radiation (sunlight), total darkness, and a complete lack of cooling by conduction and convection. In order to avoid overheating, Crew Dragon thus needs to bring along its own means of cooling in the form of onboard radiators to shed excess heat. The use of white paint on spacecraft further aids this process by selectively preventing the absorption of solar radiation while simultaneously efficiently emitting in infrared wavelengths.

HOW TO PREP YOUR DRAGON

Crew Dragon's primary radiators are elegantly integrated into vertical panels installed on the cylindrical bottom segment, known as the trunk, while the craft's power source – solar panels in this case – are installed in a curved array on the opposite side of the trunk. Intriguingly, the trunks displayed in the two most recent photos of the DM-1 Crew Dragon appear to be almost completely different, and the trunk at Plum Brook does not appear to have its solar arrays or radiators installed. Nominally, SpaceX would use the thermal vacuum capabilities of the Ohio facility to fully vet Crew Dragon's ability to maintain optimal temperatures on orbit, but the particularly tests planned for the DM-1 capsule and trunk may be of a slightly different type.


On February 28, SpaceX completed a demonstration of their ability to recover the crew and capsule after a nominal water splashdown in the Atlantic Ocean, just off the coast of Florida. (SpaceX)

Regardless, after testing at Plum Brook is completed, the DM-1 Crew Dragon capsule will be shipped to a newly-constructed processing facility in Cape Canaveral, Florida, while it's understood that the trunk installed in SpaceX's June 20th photo will be returned to the Hawthorne, CA factory to be outfitted with flight hardware (presumably including cameras, radiators, solar arrays, and a healthy amount of insulation). It's unclear when the two segments of DM-1 will part ways and head on to their next destinations, but it's likely that testing at Plum Brook will last for at least a handful of weeks.

BIRDS OF A FEATHER

In the meantime, several additional Crew Dragon capsules/trunks and the Falcon 9 Block 5 rockets that will launch them are in a variety of states of fabrication and assembly at SpaceX's Hawthorne factory. B1051, the Block 5 booster assigned to the first uncrewed Demo-1 launch of Crew Dragon, was reported by NASA to be undergoing propellant tank integration in March 2018, implying that the rocket should be at or near the final stages of integration, and will likely ship to McGregor, Texas for static fire testing late this summer.

As of June 15th, SpaceX's third Falcon 9 Block 5 booster was vertical on the Texas test stand, likely nearing its own static fire test before being shipped to SpaceX's Vandenberg Air Force Base launch facilities for the July 20th launch of Iridium-7. While possible that a booster slipped past the watchful eyes and ears of SpaceX enthusiast observers, it's probable that the rocket currently in McGregor is B1048, implying that a minimum of two additional booster shipments and Texas test programs remain before B1051 can be prepped to launch SpaceX's first Crew Dragon mission. At the current marginally accelerated booster production and shipment schedule (~ 30-day cadence), B1051 would be expected to leave Hawthorne for Texas no earlier than (NET) late August or early September. This meshes with a recent comment from Commercial Crew astronaut Suni Williams:

"I think we're going to get the [uncrewed] demo flights probably by the end of the year, maybe a little after that . . . and then the crew demo missions next year."

SpaceX's second Block 5 booster was spotted vertical at the company's McGregor, TX testing facilities. That booster has since been shipped to Florida for a mid-July launch, with B1048 now in its place as of June 15. (Aero Photo)

Anticipating acceptance and prelaunch testing that is far more extensive and time-consuming than typically seen with SpaceX's commercial missions, it's safe to bet that the first uncrewed Crew Dragon mission – DM-1 – will launch from Kennedy Space Center in November or December 2018. While those operations proceed over the course of the rest of this year, SpaceX expects roughly 10 additional Falcon 9 and Falcon Heavy launches to occur. It's gonna be a busy H2.

The Commercial Crew program will launch uncrewed ships first. SpaceX is aiming to do that in September and Boeing in October. If successful, crewed launches will follow on December 31 (Boeing) and January 17 (SpaceX).

Dragon 2 arrives at the Cape around mid July (13th?)

Это который для орбитального запуска или для испытаний САС при Q-Max?

Если ничего не изменилось, это один и тот же КК. После орбитального полёта он же планировался на Q-max.

К счастью для них, это будет не раньше чем через год

Сильно болтает только в промежутке между вытяжкой тормозного и основных парашютов. Это буквально несколько секунд.

Из-за крепления строп слишком близко к центру масс.

Kirk Shireman doesn't want to discuss dates for Commercial Crew (because there's likely some slips coming for Starliner).

Thanks to @NASA_Nerd for great photos). Most are aware of these mods, so added a bit about BFR envisioning (@jdeshetler render) as a potential next step after mods for Dragon 2.
