On the 22nd of July 2018, at 05:50 UTC a record breaking Block 5 Falcon 9 launched Telstar 19V into subsynchronous transfer orbit. Launching from Cape Canaveral Space Launch Complex 40, F9-59 (launch designation) was the First Block 5 to launch from this pad. The 7,075 kg payload was more than the previous record holder, the 6,910 kg TerreStar 1 orbited by the Ariane 5 in July 2009. Although, the previous record holder launched the satellite to full geosynchronous transfer orbit. This launch was seen as a key test of the newly developed Block 5 launch system. The first stage was recovered on the autonomous drone ship “Of Course I Still Love You” off the Florida coast.
An SSL 1300 series satellite, Telstar 19V is part of the Telstar series. Owned by the Canadian Satellite Company Telsat, it was built by Space Systems Loral (MAXAR). Using Ka and Ku band transponders it is branded as a high throughput communications satellite, designed for high bandwidth applications that the communications industry is currently dealing with. It is collocated with Telesats Telstar 14R satellite at the same position. The companies first high throughput satellite was Telstar 12V, which sits 15 degrees west.
My remote cameras worked well, & I’m happy with the long exposure I got…but capturing the @SpaceX#Falcon9 going through the supersonic regime leaving these iridescent vapor rings at an altitude of 11km is my favorite🚀 @elonmusk
The upgraded engines of the Merlin 1D engines on the Falcon 9 block 5 can produce a total of 775.65 tonnes of thrust at sea level. The second stage produces roughly 100 tonnes of thrust when in space. The first stage with the designation B1047 burned for 2 minutes and 30 seconds before separating to perform reentry and landing burns. The second stage burned for 5 minutes and 38 seconds to reach a parking orbit, stopping T+8 minutes 12 seconds. The stage restated at T+26 minutes 49 seconds for a 50 second burn to put the satellite into a 243 x 17,863 km x 27 degree orbit. The satellite will then raise itself into a geostationary orbit at 63 degrees west to cover the Americas.
A total of 26 Falcon 9/Falcon Heavy core and booster stages have now been recovered in 32 attempts. Four of those successful landings have been on “Just Read The Instructions” off the California coast, 10 have been at Cape Canaveral Landing zone 1&2, and 11 on “Of Course I Still Love You off the Florida coast. Twenty unique first stages have been recovered, with fourteen of them flying twice, and eight being expended during their second flight. All of the successfully recovered first stages have been version 1.2.
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.
On the 11th of May 2018, at 20:14 UTC the first ever block 5 Falcon 9 rocket launched Bangabandhu 1 into geosynchronous transfer orbit. Launched from Launch Complex 39A at Cape Canaveral Air Force Base, the F9-55 (launch designation) was delayed after an automatic abort on May 10th, 1 minute before liftoff. Bangabandhu 1, a Thales Alenia Space Spacebus 4000B2 series satellite is Bangladesh’s first geostationary communications satellite.
The block 5 has been long awaited by SpaceX fans, with many images in the news, and plenty of hints on Twitter. SpaceX has been incrementally improving and upgrading the Falcon 9 v1.2 booster design since it’s first launch in December 2015. Designed to be much easier to refurbish, with potentially 10 reuses in each booster. Previous block designs have only been able to be reused once before being decommissioned.
The Block 5 incorporates higher thrust Merlin 1D engines that have turboprop modifications that were requested by NASA. These modifications are to accommodate future potential crew launches. Another big change was mentioned in the livestream, where the pressurisation method in the second stage has been improved. After the AMOS 6 Falcon 9 explosion, the new version allows for faster, later and denser, chilled kerosene fuel loading. It also has new landing legs that can be retracted without being removed like previous Falcon 9’s. There are other changes, but they have been featured in previous designs.
The first stage had designation B1046. It burned for 2 minutes and 31 seconds, before separating ro perform reentry burns. It opened its new landing legs and landed on the autonomous drone ship Of Course I Still Love You, 630km downrange in the ocean. The second stage burned for 5 minutes and 43 seconds to reach parking orbit at T+8 minutes and 19 seconds. It then restarted ar T+27 minutes and 38 seconds for a 59 second long second burn that accelerated the craft to GTO.
In the 31 attempts, 25 Falcon 9/Falcon Heavy booster have been successfully recovered. Four of the landings have been on “Just Read The Instructions” off the coast of California. 10 on land at Cape Canaveral from LZ1 with another one on LZ2. 10 have landed on the autonomous drone ship, Of Course I Still Love You off the Florida coast. Nineteen individual first stages have been recovered, eleven have flown twice, with five of those ether expended or lost during their second flights. All the recovered stages have been v1.2 Falcon 9’s.
On April 18th, 2018 at 22:51 UTC a Falcon 9 took off from Launch Complex 40 at Cape Canaveral AFB. Aboard was NASA’s latest research satellite TESS. A mission that cost $337 million, Transiting Exoplanet Survey Satellite (TESS) is the latest in a line of space based observatories that are set to launch this decade. Launched into an arching elliptical orbit that will take the spacecraft over two thirds of the distance to the moon. The first stage of the Falcon 9 landed on the autonomous drone ship Of Course I Still Love You to be refurbished and reused.
After a 5 day checkout of the spacecraft, basically a hardware check, the ground controllers will switch on the TESS cameras. TESS is designed to scan around 85% of the sky during the two year mission, with astronomers estimating as many as 20,000 new planets could be found. It plans to build on discoveries made by NASA’s Kepler telescope which was launched in 2009 to find earth like planets. TESS carries four 16.8-megapixel cameras, and will look for dips in light coming from 200,000 preselected nearby stars. The four cameras cover a square in the sky that measures 24 x 24 degrees, wide enough to fit the Orion constellation into a single camera. the cameras together study a set area of sky for 27 days before staring at the next section.
The orbit TESS is being launched into is known as P/2, and requires time and finesse to reach. TESS will slingshot by the moon at a distance of around 5,000 miles (8,000 kilometers), using gravity to reshape its orbit, increasing the satellite’s orbital perigee, or low point, to the final planned altitude of around 67,000 miles. After the lunar flyby, the high point of the satellite’s elongated orbit will stretch well beyond the moon, and another thruster firing will nudge TESS into its final orbit in mid-June. Science data is planned to start in july, with the first year of the two year campaign aimed at the stars in the southern sky. TESS has been built to have enough fuel to last 20 or 30 years, assuming funding by NASA and the components on board continue to function correctly.
Each of TESS’s cameras have four custom built re-sensitive CCD sensors designed and developed by MIT’s Lincoln Laboratory. The sensors are claimed to be the most perfect CCD’s ever flown by a science mission. The lenses used by the cameras are only about 4 inches (10mm) wide, meaning it has a fairly low light collecting power compared to other space telescopes. The James Webb Space Telescope for example launching in 2020 had a 21.3ft (6.5m) primary mirror, although the satellite has cost over $8 billion to make. TESS is a bit like a finder telescope, it will lay a bedrock for future missions such as Webb and ground based observatories to make better readings. It gives a good idea of the best places to look, where the most likely exoplanets are.
TESS works by looking at a star, in this case mainly M-dwarf stars, which are cooler than our sun. They are also known as red dwarfs and make up most of the stars in our galaxy. When a planet goes in front of the star the light received by TESS “dips” and changes slightly in colour. This change in the light it receives can tell scientists alot about the size of a planet, and other things like density and velocity. They expect TESS to find between 500 and 1,000 planets that are between one and three times the size of Earth, and 20,000 planets the size of Neptune or Jupiter. The readings will give a good idea of where to focus on and ‘follow up’ on future missions. Then missions such as JWST can probe and use more complex tools to find information such as atmospheric composition, and whether they could be habitable.
The Falcon 9 used was a v1.2 with designation F9-54. It used a brand new “Block 4” first stage. The booster designated B1045 has a clear 45 written on the side in some of the close up booster images. The fist stage boosted for 2 minutes and 29 seconds, then detaching and slowing itself down. The booster landed downrange on the autonomous drone ship “Of Course I Still Love You”. The first successful drone ship landing since October 2017. A total of 24 Falcon 9 or Falcon Heavy booster stages have now been recovered in 30 attempts. Four of which were on “Just Read The Instructions” off the coast of California, ten at Cape Canaveral Landing Zone 1 and 2, and nine on the autonomous drone ship “Of Course I Still Love You” off the Florida Coast. 18 first stages have been recovered, 11 of which have flown twice, five have been lost during their second flight. B1045 was the last brand new “Block 4” Falcon 9 booster.
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.
At 14:13 UTC on March 30th 2018, SpaceX launched a Falcon 9 from foggy Vandenberg Air Force Base. Although designated F9-52 this was the 51st Falcon 9 launch. Using a v1.2 variant booster, the rocket delivered 10 Iridium NEXT satellites into orbit. This was the fifth of eight planned Iridium NEXT missions.
From Vandenberg AFB Space Launch Complex 4 East, the first stage of the rocket lasted 2 minutes 34 seconds, separating a few seconds after. The second engine fired for 6 minutes 23 seconds. This part of the webcast was purposefully cut short due to a NOAA remote sensing licensing requirements. This is an issue with SpaceX not having the right licence to broadcast images from certain parts of space. This burn placed the rocket in a roughly 180 x 625 km parking orbit. The Thales Alenia Space satellite then deployed an hour after launch, after a second brief 11 second burn. This put the satellites into a 625km x 86.6 deg orbit.
The rocket used another “Fairing 2.0”, which is slightly larger than usual, but equipped with recovery systems. These systems include thrusters, a guidance system, and a parafoil. The ship, named Mr Steven has a large net to capture the halves of the fairing. Again, the ship failed to catch one of the fairings, due to a parachute system issue. In a tweet by Elon Musk, it was reported that the GPS guided parafoil twisted so the fairing impacted the water at high speed. He also said that SpaceX are doing helicopter drop tests to fix the issue.
Five of the six previously used Falcon 9 vehicles have been fully expended, this was the tenth flight of a previously-flown Falcon 9 first stage. Four of these ten have been purposely expended during their second flight. The first stage (B1041.2) was previously flown during the Iridium NEXT 3 launch on October 9th, 2017. It performed the 2 minute 34 second boost, and performed what SpaceX call a “simulated landing” into the ocean. SpaceX appear to be only launching a reused stages for one reflight, with the soon to launch “block 5” likely to be reused multiple times. Currently the company only have 4 first stages that might be flown, with one allocated for the upcoming CRS-14 dragon resupply mission.
At 05:33 UTC on March 6th 2018 SpaceX launched it’s 50th Falcon 9 mission. The version 1.2 Falcon 9, with a brand new “Block 4” variant booster B1044, lifted off from Cape Canaveral Space Launch Complex 40. On board, inside the type 1 fairing was Spain’s Hispasat 30W-6. Weighing in at 6,092kg, being the size of a bus and being launched into geosynchronous transfer orbit, it’s the biggest challenge that the Falcon 9 has come up against.
Falcon 9 flight 50 launches tonight, carrying Hispasat for Spain. At 6 metric tons and almost the size of a city bus, it will be the largest geostationary satellite we’ve ever flown.
The First stage if the Falcon 9 fired for about 2 minutes and 35 seconds before releasing and plummeting back towards the Atlantic ocean. The initial plan was top land the “type 4” first stage on the autonomous drone ship “Of Course I Still Love you” in the Atlantic. Landing legs and titanium steering grid fins were attached and went up with the rocket. There was already speculation, due to the large payload and the orbit attempted, whether the Falcon 9 would have enough fuel left to attempt the reentry and landing procedure. Unfortunately it was not possible to find out whether the F9-51 mission would have made a landing because the autonomous drone ship was kept in port because of high sea conditions. The rocket still went through the entire reentry and landing procedure, as mentioned on the livestream, but ended up in the Atlantic.
almost 9 minutes in, the second stage with the payload achieved a Low Earth Orbit, and “parked” until T+26 min 36s where they first crossed the equator. This second burn lasted 55 seconds to accelerate the ss/Loral-built satellite into a Geosynchronous Transfer Orbit. The Hispasat 30W-6 will fire its four SPT-100 plasma thrusters to gradually raise itself to Geosynchronous Orbit positioned 30 degrees West (clue in the name). Hispasat 30W-6 is designed to provide broadband services in Europe and Northwest Africa.
This is the fourth all-expendable Falcon 9 launch in the past 5 years, and the first time a “type 4” stage has been expended on it’s first flight. Both of the stages of the F9-51 rocket were tested at SpaceX Rocket Test Facility in McGregor, TX during October/November 2017. They have been at Cape Canaveral since January 2018, and were stacked ,loaded with propellant and tested (first stage only) at the Cape at SLC 40 on February 20, 2018. The Launch was initially planned for February 25th, but was shelved by SpaceX to investigate payload fairing pressurisation issues.
At 20:45 UTC on the 6th of February 2018 the long awaited Falcon Heavy soared up into the sky. Watching the livestream, there was something slightly different. Instead of the usual single commentator, they had four. Behind them, hundreds of SpaceX employees cheering all the way through the launch, with bigger cheers at each milestone. It was definitely long anticipated, and I even felt the impact at university. Students were going round making sure people knew that tonight was the night that the Falcon Heavy was launching. The stream didn’t disappoint space lovers, and I highly recommend watching it on the SpaceX Youtube page.
So what actually happened, why was this flight so important? The demo mission was the first firing of the full Falcon Heavy configuration. Although all the rockets had been previously fired and tested at SpaceX’s rocket test facility in McGregor, TX. Consisting of “Block 2” variant side boosters (B1023.2 and B1025.2) and a “Block 3” variant core stage (B1033.1). Both the boosters had been flown before and refurbished in Hawthorne, CA. B1023.2 was flown May 27th, 2016 for Thaicom 8 launch, landing on SpaceX’s autonomous drone ship “Of Course I Still Love You”. B1025.2 flew on July 18th, 2016 for the CRS-9 mission, landing at Landing Zone (now landing zone 1). It is noted that future Falcon Heavies will likely use the “Block 5” variant. Elon Musk Claims that the development of the Falcon Heavy project has cost $500 million to get to this stage.
At 20:45 UTC, the Falcon Heavy lifted off of pad 39A at Kennedy Space Centre. It weighed roughly 1,400 tonnes and was 70m tall. with 2,128 pounds of thrust, the triple barreled rocket lifted off the pad with its 27 Merlin 1D engines (9 on each booster). At the time of writing it is the largest and most powerful operational rocket in use today by a factor of 2. Elon Musk gave the launch a 50-50 chance of success, but it continued through almost all of the milestones. Through Max-Q, release of boosters, and release of the main engine. The second stage performed 3 burns during the 6 hour mission to accelerate the cargo to into a heliocentric orbit. The orbit ranges from earth orbit to beyond mars (0.99 x 1.71AU). The concept of this burn was to demonstrate long coasts between the second and third burns. This ability is needed for some DoD EELV Heavy class missions, a market that SpaceX wants to compete in.
Usually on these types of initial flights they put some sort of simulated weight in the fairing (the bit that holds the payload on top) usually a block of concrete. Elon Musk being Elon saw this as a marketing opportunity, and instead used his personal 2008 cherry red Roadster, weighing in at 1,250kg. In the driver’s seat sat a full scale human mannequin named “Starman”, wearing a SpaceX branded pressure spacesuit. The person who timed the release of the fairing showing the Tesla against the backdrop of the earth, to the music of “Life of Mars” by David Bowie, deserves a medal. Although perfectly timed, it is sometimes incorrectly attributed as “Starman” by Bowie, which would make more sense when you think about it. On the dashboard of the car is the immortal words of “don’t panic”, a tribute to A Hitchhiker’s Guide to the Galaxy, that was a clever addition. There is a livestream of the first 5 hours of Starmans trip, at which time it probably lost signal, or ran out of battery. There has been mixed reviews of this stunt. Some call it art, whereas others call it “space littering”. Some commentators such as Burnie Burns on the Roosterteeth Podcast simply don’t like the use of space for marketing purposes. Scientists at Purdue University called it “the dirtiest man-made object ever to be sent to space” due to its use driving in Los Angeles.
For me personally the most impressive part of the entire video was near to the end. SpaceX have had some famous problems with the landing of their reusable rockets, but during this mission they planned to land all three. The best shot of the entire livestream was the two boosters coming down at the same time, with the Cape in shot. Both boosters opening their landing legs, and coming down to land on Landing Zone 1 and 2. It was a truly epic sight, and from an engineers point of view, very impressive. The second pad was installed for these Falcon Heavy missions, and the boosters worked just as planned. The core was a slightly different story. It attempted to land on the autonomous drone ship “Of Course I Still Love You”. It completed its boost-back and reentry burn, but for the three-engine landing burn, two engines failed to ignite. The core ended up in the Atlantic. Smoothly brushed over, this was not mentioned on the Livestream, and not until a few hours later on Twitter. Even so, the things that did land correctly were impressive.
There has been a huge amount of excitement and skepticism about the Falcon Heavy. Some have heralded it the way Elon Musk wants to get to Mars, others just love the idea that the car will be out there for “billions of years”. Although very impressive, the Falcon heavy is really designed to be a beefier version of the Falcon 9, and will probably do the same job. SpaceX are aiming in the coming years to get more contracts from the Department of Defence, and aim to get more up into space at the same time. The Falcon Heavy is all about making it cheaper for big payloads to get to space. Although it has the capability to get to Mars, and carry people, Musk has said that there are bigger plans in the pipeline for those jobs. As for the car, according to chemist William Carroll, solar and cosmic radiation will break down most of the car within a year, leaving just the aluminium frame and maybe some glass that isn’t shattered by meteorites.
This is a big moment for SpaceX, and the space community, and shows that there are big things coming in the sector. There are big launches aimed from the big companies this year, and new rockets being unveiled in the near future. SpaceX may have just started a new space race. For all the excessive marketing that Elon Musk does, SpaceX have definitely got their marketing message right.
