May 20th 2012 - 07:00 UTC

At T-40 minutes the launch team will put the Falcon 9 rocket into it's final setup ahead of launch, this should take about 20 minutes.

May 20th 2012 - 06:55 UTC

President of SpaceX, Gwynne Shotwell, says the issue that scrubbed Saturday's launch was 'pretty obvious' once engineers were at the pad.

May 20th 2012 - 06:48 UTC

A weather briefing was given at T-1 Hour, Forecasts show very few clouds with just a couple scattered clouds at 2500 feet not a threat at all for launch. Winds have picked up a bit to 10 knots and brought the temperature down to 73 F but no flight rules have been breached giving a 'GO' to launch from the weather stand point.

May 20th 2012 - 06:45 UTC

A weather balloon has been released to check upper level winds as everything looks good for launch today. Countdown clocks have just passed T-1 Hour and counting.

May 20th 2012 - 06:00 UTC

The strongback has lowered to launch position from the rocket as it sits fully fueled awaiting lift off at 07:44 UTC from Space Launch Complex 40.

May 21st 2012 - 19:44 UTC

It is now T-12 Hours and counting until the second launch attempt of a Falcon 9 rocket with the Dragon Spacecraft from Space Launch Complex 40 at Cape Canaveral in Florida.

Weather shows a 80% chance of favourable conditions for lift off at 07:44 UTC, 03:44 Local time as SpaceX will try to become the first commercial company to send a vehicle to the International Space Station.

Both vehicles will be powered on at T-7:30 Hours into the count and fueling will begin at T-3:50 Hours.

May 20th 2012 - 14:50 UTC

It's a 'GO' for launch on May 22nd 2012 at 07:44 UTC, 03:44 Local time.

May 21st 2012 - 10:40 UTC

With the faulty valve successfully replaced and shown to be working on the Merlin engine 5 of Falcon 9's first stage clocks continue to tick down to tomorrows launch window at 07:44 UTC, 03:44 local. SpaceX engineers will continue to examine the situation today as they check everything is in working order before they confirm a 'GO' for launch tomorrow.

The original launch attempt on May 19th 2012 was scrubbed due to a high pressure reading in the engine chamber of engine 5, The countdown was then aborted at T-0.5 seconds, after the engines had already fired up.

May 20th 2012 - 11:45 UTC

The problem has been narrowed down to a faulty check valve which is being replaced, If all goes well launch will occur May 22nd 2012 at 07:44 UTC.

May 19th 2012 - 10:50 UTC

More information on the abort will be released after the engine has been inspected, Lift off on May 22nd would occur at 07:44 UTC, 03:44 Local time. A launch on May 23rd would occur at 07:22 UTC, 03:22 Local time and an opportunity on May 24th is also available, occurring at 07:00 UTC, 03:00 Local time.

May 19th 2012 - 10:44 UTC

A high chamber pressure could be caused by low fuel flow, however the pre-valve was fully open as is expected so they are not sure what has happened. They will check the engine visibly at the pad and borescope the pump, they will only disassemble if necessary.

May 19th 2012 - 10:43 UTC

SpaceX: "All nine engines fired and trended nominally, then engine 5 chamber pressure trended high".

May 19th 2012 - 10:41 UTC

SpaceX have plans in place to replace engine 5 with an engine from the next Falcon 9 vehicle that is at the Cape if necessary, they say it would take a few days if they were to do so.

May 19th 2012 - 10:38 UTC

SpaceX state it does not appear to be a sensor failure on engine 5, The abort was called by the computer at T-0.5 seconds.

May 19th 2012 - 10:35 UTC

SpaceX say they will have technicians out to the launch pad checking the engines by noon local time for any issues. Launch attempts are available on the 22nd and the 23rd and the Space Station is ready to support whenever SpaceX is ready to launch.

May 19th 2012 - 10:20 UTC

The sun is rising over Space Launch Complex 40 where the Falcon 9 sits, the teams are continuing to drain the vehicle of propellants after today's abort.

May 19th 2012 - 09:35 UTC

Video of the launch abort is now available at the bottom of this page.

May 19th 2012 - 09:00 UTC

The next launch attempt is May 22nd 2012 at 07:44 UTC, 03:44 Local time.

May 19th 2012 - 09:00 UTC

The cause of the abort was due to a high chamber pressure reading on engine 5 of the first stage. After the main engines ignited a routine check of all parameters are checked by the on board computers before the hold down system on the pad releases the rocket, the computer saw a value out of alignment and safed the vehicle as designed. The next available launch attempt is May 22nd however this has not yet been confirmed.

May 19th 2012 - 08:55 UTC

The engines have ignited but there has been an abort.

May 19th 2012 - 08:54 UTC

The next major milestone will be the start of the terminal count at T-10 Minutes.

May 19th 2012 - 06:11 UTC

Fueling began this morning at around 05:40 UTC as the Falcon 9 sits patiently at the pad.

May 18th 2012 - 20:55 UTC

The countdown has reached T-12 hours and counting, the major events coming up are Falcon 9 and Dragon power up at T-7:30 Hours. Fueling will begin just under 4 hours later as the start of the liquid oxygen (LOX) fuel loading begins at T-3:50 Hours and rocket grade kerosene (RP-1) 10 minutes later at T-3:40 Hours.

Once fueling has completed 25 minutes later the count continues until the start of terminal countdown autosequence at T-10:30 Minutes. At T-2 Minutes the SpaceX Launch Director and Range Control officer will give a 'GO' for launch if all is well, The water systems on the pad will turn on at T-1 Minute, the propellent tanks in the Falcon 9 first and second stage will pressurise to flight levels and then at T-3 seconds the nine Merlin main engines will ignite for lift off at T-0. The nine main engines will power the vehicle for the first 3 minutes of flight, separating 5 seconds later. The single engine Merlin second stage will ignite at T+3:12 Minutes and will continue to burn for 6 minutes. At T+3:52 Minutes the Dragon spacecraft's nose cone will be jettisoned. After a successful cut off of the second stage at T+9:14 Minutes the Dragon spacecraft will separate at T+9:49 Minutes having safely arrived in Orbit.

One of the first on orbit operations and demonstrations for the Dragon will be the deployment of the two solar arrays, each made up of 4 solar panels. This will occur at T+11:53 Minutes into flight. The first day in orbit will also include the deployment of what is called the GNC Bay Door, On this door are the required sensors for rendezvous and flyaround of the International Space Station. Finally with the GNC Bay Door open demonstrations of various equipment, sensors, ability to free drift and abort scenarios of the Dragon spacecraft will be performed.

On flight day 2 the Dragon will continue it's flight to the International Space Station through carefully planned burns of it's eighteen Draco thrusters.

Flight day 3 will include a fly under of the Space Station at 2.5 km below the Station, this will allow the Dragon to test it's GPS systems and for crew onboard the Station to send and receive commands to it from the Cupola module. This test is crucial in confirming the crew are about to control the spacecraft and guide it towards the Station for berthing with the Stations Robotic Arm. With all these tests complete the Dragon will conduct a burn to carry itself away from the Station.

On flight day 4 or 'Capture Day', will be the ultimate test. Dragon will conduct another burn to reach within 2.5 km of the Station again and with approval from the ground will conduct a height adjustment burn to reach 1.2 km distance between it and the Station. Further burns will bring the Spacecraft into the approach path, Various NO GO/GO holds will be conducted at 250 meters, 30 meters and 10 meters. If all goes well the final NO GO/GO to capture the Dragon will be given.

Don Pettit on-board the International Space Station in the Cupola will control the Stations Robotic Arm and capture the Dragon through it's grapple fixture, the arm will then maneuver with the grappled Dragon and berth it to the Harmony module of the Station.

The Dragon is carrying 520 kg of cargo including crew clothing, food and various equipment for experiments. It will also become the first cargo vehicle at the Station able to return cargo, It will return 660 kg of cargo including various hardware that has failed or needs returned for examination on Earth as well as some experiment items.

May 18th 2012 - 17:55 UTC

All launch windows are instantaneous so if the Falcon 9 cannot get off the pad at 08:55 UTC tomorrow the next attempt is May 22nd. After May 22nd there are good opportunities on May 25th and May 29th, Opportunities are also on May 23rd and May 26th but negotiations would be required.

After May 29th a beta cut out from the sun brings the next opportunity to the late teens of June 2012.

Launch attempts are set apart by three days to save propellent in the Dragon Spacecraft as the delay allows the International Space Station to be closer to the launch site and easier to reach.

May 18th 2012 - 17:00 UTC

Weather for tomorrow has light rain showers with thunderstorms drifting in the area however thunderstorms are very rare during the morning launch time with morning and overnight weather being the best of the entire day.

Winds are favourable at 5-10 knots with a scattered cloud deck at 2500ft. The overall chance of launch is 70% with the primary concern being the Cumulus Cloud Rule.

May 18th 2012 - 12:00 UTC

The Falcon 9 rocket has been rolled out to the launch pad at Space Launch Complex 40 at Cape Canaveral in Florida after getting a unanimous 'GO' to launch on May 19th 2012 at 08:55 UTC.
