The Final Block 4 Changes the Florida Sky

On the 29th of June 2018, at 09:42 UTC the last Block 4 type Falcon 9 rocket launched a cargo mission to the International space station. Launching from Space Launch Complex 40 at Cape Canaveral Air Force Base, the Falcon 9 was carrying CRS-15, a resupply for the International Space Station (ISS). This is the 15th mission of up to 20 CRS missions that have been contracted with NASA to resupply the ISS. Initially planned for April 2018, it was eventually pushed to the 29th of June. Previous resupply missions have been conducted by SpaceX and Orbital ATK.

B1045 (the first stage booster) was the seventh and final “Block 4” Falcon 9 v1.2 first stage manufactured by SpaceX. For this reason it is very likely that this was the final Block 4 first stage orbital vehicle. SpaceX has since developed the Block 5 the debuted in May. Together the seven Block 4 Falcon 9’s boosted twelve missions, with most being expended on the second flight. This stage was purposely expended at the end of the mission, the ninth purposeful expenditure in the last twelve launches. This stage was not equipped with landing legs or titanium steering grid fins. It was the 14th flight of a previously flown Falcon 9 first stage, and the eighth to be expended on the second flight.

B1045.2 had previously boosted NASA’s TESS towards orbit on April 18th 2018, I wrote about that launch here. With it returning to the autonomous drone ship “Of Course I Still Love You” downrange. For this mission it launched the two stage rocket and powered it for 2 minutes and 51 seconds. With a Dragon 11.2 refurbished spacecraft that was previously used on CRS-9 in July 2016 the main payload for the rocket. The first put the capsule and the second stage into a 227 x 387 km x 51.64 degree orbit. The block 5 second stage burned for about 8 minutes and 31 seconds after liftoff, inserting Dragon into the required orbit. The burn was 36 seconds shorter than previous Block 4 launches as this rocket had higher thrust. Dragon rendezvoused with the ISS on the 2nd of July after an extended coast.

This launch left a particularly cool looking smoke cloud afterwards. With many Twitter users posting images of the smoke remnants hundreds of miles away. The night launch also allowed for some great photos by many of the keen photographers that are at every launch, capturing many of the images in this post. To see more of the awesome rocket launches, I have posted about many, and will continue to do so.

Falcon 9 Re-Supplies the ISS on CRS-14

On April 2nd, 2018 at 20:30 UTC a Falcon 9 took off from Launch complex 40 at Cape Canaveral AFB. Aboard was a refurbished Dragon capsule with CRS-14, a resupply for the ISS. This was the 14th of up to 20 CRS missions contracted with NASA, with new Crew Dragon variants soon to be used. The capsule safely reached the ISS and was docked 20 minutes earlier than planned. The cost of the mission was reported to be around $2 billion, and comes under a contract between NASA and SpaceX.

The Dragon capsule carried 2,630kg  of cargo to the International Space Station, including supplies and research equipment. it has 1070 kg of science equipment, 344 kg of supplies for the crew, 148 kg of vehicle hardware, 49 kg of advanced computer equipment and 99 kg of spacewalking gear. Aboard there are a number of experiments, such as a new satellite designed to test methods of removing space debris. There are also frozen sperm cell samples, a selection of polymers and other materials, all experiments to test what happens to different items when exposed to space and microgravity.

Designated F9-53, the Falcon 9 used booster B1039.2, which previously boosted the CRS-12 mission in August 2017, where it returned to landing zone 1. As is customary, the first stage was left “sooty” from it’s first flight. It powered for 2 minutes and 41 seconds before falling back to earth. For the sixth time in the last 7 Falcon 9 launches, the first stage was purposefully expended, even though it carried landing legs and steering grid fins. As with other expenatures, the rocket went through the re-entry landing sequence, but just didn’t have anything to land on and ended up in the sea. It was the 11th flight of a previously flown Falcon 9 first stage, five of which have been purposefully expended during the second flight, only 3 first stages remain that can be reflown.

The second stage completed its burn at 9 minutes and 11 seconds after takeoff, to insert Dragon into a Low Earth Orbit inclined 51.6 degrees to the equator. The Dragon 10.2 is a refurbished spacecraft capsule that first flew during the CRS-8 mission in April 2016. CRS-14 was the third launch of a previously flown Dragon capsule. This was also the first time that both the Dragon capsule and the Falcon 9 were refurbished versions on the same rocket. The docking process was carried out for around 20 minutes, and at 10:40 UTC Kanai detached the lab’s robotic arm to hook the free-flying Dragon capsule. At around 12:00 UTC Houston and Canada took control of the robotic arm and maneuvered it to the Harmony capsule of the ISS. It will be unpacked in a very slow process over a number of months.
