SpaceX Dragon CRS-5 ISS resupply

Launch date: Dec. 9, 2014

Window: 1715 Local (Eastern)

This date could move because of cargo shuffling caused by the Antares/Cygnus explosion. At the least a large high pressure nitrogen tanks backup will be loaded into Dragon, replacing a lower priority high pressure oxygen tank.

The Cygnus loss will ripple through not only the Dragon manifests but HTV and Progress as well.

Trunk payload,

Cloud-Aerosol Transport System (CATS), a laser instrument to measure clouds and the location and distribution of pollution, dust, smoke, and other particulates in the atmosphere. The laser will operate at wavelengths of 355, 532 and 1064 nm.

A stage landing on a 300x170 foot catamaran barge is planned, assuming it's completed in time. They're pushing hard. The barge will use GPS and thrusters for stabilization.

FAA docs posted on NASASpaceFlight about the barge radio beacons show if it is used the landing will be offshore of Jacksonville, Florida at North 30 49 54, West 78 6 29.

NASASpaceFlight reports,

http://www.nasaspaceflight.com/2014/11/crs-5-dragon-mission-iss-evaluating-december-target/

Launch: December 16, with back up dates of the 19th and 20th.

Berthing at ISS: December 18, if launched on the 16th.

Cargo (pressurized): 3,310 kg (7,300 lb).

CRS-5's first stage will be the first to use the grid fins developed on F9R Dev-1. These are used for both hypersonic and subsonic steering during stage landings.

Yup.

As to the launch time, it should be around 1430 Local (Eastern) with the landing ~8 minutes later. Instant window, no slack.

It would be so damned cool if they had quadcopter mounted cams on the air shooting 4K video :)

The updated Dec. 1 FCC application for CRS-5 launch and ship frequencies gives the coordinates for ASDS and it's tender ship.

Some NSF users have driven or kayaked by the ASDS construction & painting sites and it's gone, presumably on it's way to Florida.

From the FCC docs,

So what does this mean?

 

The change of launch date allows SpaceX to take extra time to ensure they do everything possible on the ground to prepare for a successful launch. Both the Falcon 9 rocket and its Dragon spacecraft are in good health.

 

Just that SpaceX wanted more time? Or is a NASA ass covering?

>

The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, were targeting a landing accuracy of within 10 meters.

A key upgrade to enable precision targeting of the Falcon 9 all the way to touchdown is the addition of four hypersonic grid fins placed in an X-wing configuration around the vehicle, stowed on ascent and deployed on reentry to control the stages lift vector. Each fin moves independently for roll, pitch and yaw, and combined with the engine gimbaling, will allow for precision landing first on the autonomous spaceport drone ship, and eventually on land.

The static fire is just part of it. Even a short delay at this point causes problems with both the KSC holiday schedule and ISS's Beta Angle.

Basically, ISS's orbital plane is entering a point in its cycle where the station is in constant sunlight. This can cause thermal problems for visiting vehicles, so launches are delayed until this is relieved. Early January is the next opportunity.

The Beta Angle for ISS cycles between -75 and +75 degrees. When it exceeds 60 degrees, which happens a few times a year, there's too much Sun exposure for visiting vehicles and they overheat. Even the Shuttle.

A BEO (lunar, Mars etc.) version of a vehicle is designed to handle this, larger radiators etc., but for ISS taxis that would sacrifice cargo capability.

Another thing a BEO vehicle can do is orient itself so it's smallest surface faceless the Sun during y he trip, example being Dragon's trunk or a future service module, but that's not possible when docked.

NASA, SpaceX Update Launch of Fifth SpaceX Resupply Mission to Space Station

NASA and SpaceX announced today the launch of SpaceX's fifth commercial resupply services mission to the International Space Station now will occur no earlier than Tuesday, Jan. 6.

The new launch date will provide SpaceX engineers time to investigate further issues that arose from a static fire test of the Falcon 9 rocket on Dec. 16 and will avoid beta angle constraints for berthing the Dragon cargo ship to the station that exist through the end of the year.

A beta angle is the position of the sun relative to mechanical structures on the space station. During the time of high beta angles, which run from Dec. 28 through Jan. 7, thermal and operational constraints prohibit Dragon from berthing to the station.

Space station managers will meet Monday, Jan. 5, for a readiness review in advance of the launch attempt Jan. 6. The launch postponement has no impact on the station's crew or its complement of food, fuel and supplies and will not affect the science being delivered to the crew once Dragon arrives at the station.

The launch is scheduled at approximately 6:18 a.m. EST. NASA Television coverage will begin at 5 a.m.

A backup launch attempt is available Wednesday, Jan. 7.

A launch on Jan. 6 will result in a rendezvous and grapple of Dragon Thursday, Jan. 8, at approximately 6 a.m. NASA TV coverage will begin at 4:30 a.m. Installation coverage will begin at 9 a.m.

Prelaunch briefings at NASA's Kennedy Space Center in Florida will be rescheduled for Monday, Jan. 5, with times still to be determined.

They really need to get these things sorted, I know nearly all of their launches were successful, however how many of them have been delayed, it seems like every launch is delayed. Not all their fault, but im impatient and want things now. I was going to get up and watch this one, but I suppose I will have to walk down the street and look at the Tesla's through the window.

http://www.spacex.com/press/2014/12/19/crs-5-launch-update

Today, SpaceX completed a successful static fire test of the Falcon 9 rocket in advance of the CRS-5 mission for NASA. The test was conducted at SpaceX?s Launch Complex 40 at Cape Canaveral Air Force Station, Florida, and ran for the full planned duration.

SpaceX also conducted a static fire test on December 17 and while the test accomplished nearly all goals, it did not run the full duration. The data suggested we could have pushed forward without a second attempt, but out of an abundance of caution, we opted to execute a second test.

Given the extra time needed for data review and testing, coupled with the limited launch date availability due to the holidays and other restrictions, our earliest launch opportunity is now January 6 with January 7 as a backup. A few times a year, the ISS orbits through a high beta angle period. This is where the angle between the ISS orbital plane and the sun is high, resulting in the ISS being in almost constant sunlight for a 10 day period. During this time, there are thermal and operational constraints that prohibit Dragon from being allowed to berth with the ISS. This high beta period runs from December 28, 2014 ? January 7, 2015. Note that for a launch on January 6, Dragon berths on January 8.

After today?s successful static fire, our teams are looking forward to launch just after the New Year.
