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.
In early 2005, two security officers at Cape Canaveral Air Force Base in Florida were doing a check of a facility known as the Launch Complex 5/6 museum. NASA Special Agent Dann E. Oakland and Security Manager Henry Butler, of the company that oversees the museum, Delaware North Parks and Resorts, discovered a locked room. The problem was they had no key, and nobody else did! Luckily, being security officers they found a master key and gained entry. By the looks of things the room hadn’t been accessed in many years, at least not by people, the rodents had made themselves at home. With no power the officers explored with torches and found some interesting stuff.
They found retired spacesuits designed for Americans in the 1960’s that were training to be space spies. Initially they assumed the spacesuits were training suits from the end of Gemini or the beginning of Apollo space programs. When inspected by their manufacturer, the Hamilton Standard Corporation, they determined they were actually MH-7 training suits. Kept in surprisingly good condition, the suits were made for a short lived cold war-era military program to put a manned space station in orbit.
In 1964 the Manned Orbiting Laboratory program was an Air Force initiative to send a Air Force astronauts to a space station in a Gemini capsule, as they had plenty of experience with it. While up there they would take part in surveillance and reconnaissance efforts. After spending a few weeks in orbit, the crew would simply un dock and return to Earth. A test launch from Complex 40 on Nov. 30, 1966, of a MOL was conducted with an unmanned Gemini capsule. The MOL was constructed from tankage of a Titan II rocket. The program was abandoned by the Air Force in 1969 but not before they made a great deal of technological developments. when the USAF abandoned the MOL program, they transferred all equipment and their astronaut corps to NASA.
There were two spacesuits found, one identified as 007 and another 008. The spacesuit with identifying number 008 had the name “LAWYER” on the left sleeve. The suit was traced to Lt. Col. Richard E. Lawyer, a member of the first group recruited to be MOL astronauts in 1965. Three groups of military officers trained to be MOL astronauts, when the program was cancelled seven of the younger ones were transferred to NASA’s human space flight program, and went on to have standout careers. Notable mentions are Robert Crippen, pilot of the first Space Shuttle mission, and Richard H. “Dick” Truly, who later became a NASA Administrator. All MOL astronauts who were under age 35 and survived eventually flew in NASA programs, either on board Skylab or the space shuttle.
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.
At 23.13 UTC on April 14th 2018 the third Atlas 5 launch of the year fired multiple military satellites into a near geosynchronous orbit. Launching from Space Launch Complex 41 at Cape Canaveral, FL, the AV-079 (the launch designation) was an Atlas V in 551 configuration. The rocket had 5 solid rocket motors, a Centaur second stage powered by a single RL10C-1 LOX/LH2 engine, and a 5m diameter payload fairing. The entire mission lasted approximately 7 hours and is known as Air Force Space Command (AFSPC) 11 mission.
The mission lifted two primary satellites for the Air Force, one stacked on top of the other. On the top was CBAS (Continuous Broadcast Augmenting SATCOM) an abbreviation within an abbreviation, and a military communications satellite. The second satellite was named EAGLE (ESPA Augmented GEO Laboratory Experiment) which is an abbreviation with two abbreviations in it! This satellite is based on an Orbital ATK ESPA bus, it is a research laboratory that can host 6 deployable payloads. It is said that EAGLE likely weighed around 780 kg. There was also a subsatellite named “Mycroft” reported to be on the flight, but not confirmed.
The Solid motors finished their burn and seperated 1 minute and 47 seconds after liftoff. The first stage, an RD-180 rocket fired for 4 minutes and 33.5 seconds. Centaur then performed 3 burns which were not shown on the livestream. The first burn was meant to last 6 minutes 1 seconds to reach a low earth parking orbit. The second burn began 12 minutes and 6 seconds after the first cutoff, and last 4 minutes and 49 seconds, putting the vehicle into a geosynchronous transfer orbit. After a 5 hour and 6 minute apogee, a third burn of 2 minutes and 36 seconds completed the insertion to the planned orbit. A spacecraft separation extended for another 1 and a half hours to T+6 hours 57 min 24 sec.
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.
On February 1st, 1958 at 03:48 UTC (January 31st at 22:48 EST), the first Juno booster launched Explorer 1 into Low Earth Orbit. It was the first satellite to be successfully launched by the United States, and the third ever, after Sputnik 1 and 2 in 1957. Launched from the Army Ballistic Missile Agency’s (ABMA) Cape Canaveral Missile Annex in Florida, now known as Launch Complex 26. The launch played a pivotal part in the discovery of the Van Allen Belt, Explorer 1 was the start of the Explorer series, a set of over 80 scientific satellites. Although sometimes looked over in the history of space, it guided the US space program to what it eventually became.
In 1954 The US Navy and US Army had a joint project known as Project Orbiter, aiming to get a satellite into orbit during 1957. It was going to be launched on a Redstone missile, but the Eisenhower administration rejected the idea in 1955 in favour of the Navy’s project Vanguard. Vanguard was an attempt to use a more civilian styled booster, rather than repurposed missiles. It failed fairly spectacularly in 1957 when the Vanguard TV3 exploded on the launchpad on live TV, less than a month after the launch of Sputnik 2. This deepened American public dismay at the space race. This lead to the army getting a shot at being the first american object in space.
In somewhat of a mad dash to get Explorer 1 ready, the Army Ballistic Missile Agency had been creating reentry vehicles for ballistic missiles, but kept up hope of getting something into orbit. At the same time Physicist James Van Allen of Iowa State University, was making the primary scientific instrument payload for the mission. As well this, JPL director William H. Pickering was providing the satellite itself. Along with Wernher Von Braun, who had the skills to create the launch system. After the Vanguard failure, the JPL-ABMA group was given permission to use a Jupiter-C reentry test vehicle (renamed Juno) and adapt it to launch the satellite. The Jupiter IRBM reentry nose cone had already been flight tested, speeding up the process. It took the team a total of 84 days to modify the rocket and build Explorer 1.
The satellite itself, designed and built by graduate students at California Institute of Technology’s JPL under the direction of William H. Pickering was the second satellite to carry a mission payload (Sputnik 2 being the first). Shaped much like a rocket itself, it only weighed 13.37kg (30.8lb) of which 8.3kg (18.3lb) was the instrumentation. The instrumentation sat at the front of the satellite, with the rear being a small rocket motor acting as the fourth stage, this section didn’t detach. The data was transmitted to the ground by two antennas of differing types. A 60 milliwatt transmitter fed dipole antenna with two fiberglass slot antennas in the body of the satellite, operating at 108.3MHz, and four flexible whips acting as a turnstile antenna, fed by a 10 milliwatt transmitter operating at 108.00MHz.
As there was a limited timeframe, with limited space available, and a requirement for low weight, the instrumentation was designed to be simple, and highly reliable. An Iowa Cosmic Ray instrument was used. It used germanium and silicon transistors in the electronics. 29 transistors were used in the Explorer 1 payload instrumentation, with others being used in the Army’s micrometeorite amplifier. The power was provided by mercury chemical batteries, what weighed roughly 40% of the total payload weight. The outside of the instrumentation section was sandblasted stainless steel with white and black stripes. There were many potential colour schemes, which is why there are articles models and photographs showing different configurations. The final scheme was decided by studies of shadow-sunlight intervals based on firing time, trajectory, orbit and inclination. The stripes are often also seen on many of the early Wernher Von Braun Rockets.
The instrument was meant to have a tape recorder on board, but was not modeled in time to be put onto the spacecraft. This meant that all the data received was real-time and from the on board antennas. Plus as there were no downrange tracking stations, they could only pick up signals while the satellite was over them. This meant that they could not get a recording from the entire earth. It also meant that when the rocket went up, and dipped over the horizon, they had no idea whether it got into orbit. Half an hour after the launch Albert Hibbs, Explorers System designer from JPL, who was responsible for orbit calculations walked into the room and declared there was a 95% chance the satellite was in orbit. In response, the Major snapped: “Don’t give me any of this probability crap, Hibbs. Is the thing up there or not?”.
The instrument was the baby of one of Van Allens graduate students, George Ludwig. When he heard the payload was going into the Explorer 1 (and not the Vanguard) he packed up his family and set off for JPL to work with the engineers there. He has a good oral history section on this link, talking about designing some of the first electronics in space. He was there watching the rocket launch and waiting for results. From the Navy’s Vanguard Microlock receiving station they watched the telemetry that reported the health of the cosmic-ray package. The first 300 seconds were very hopeful, with a quick rise in counting rates followed by a drop to a constant 10-20 counts per second, as expected. The calculations told them when they should hear from the satellite again, but 12 minutes after the expected time, nothing showed up but eventually, after pure silence, Explorer 1 finally reported home.
Once in orbit, Explorer 1 transmitted data for 105 days. The satellite was reported to be successful in its first month of operation. From the scientist point of view, the lack of data meant the results were difficult to conclude. The data was also different to the expectations, it was recording less meteoric dust than expected and varying amounts of cosmic radiation, and sometimes silent above 600 miles. This was figured out on Explorer 3 when they realised the counters were being saturated by too much radiation. Leading to the discovery of the Van Allen Radiation Belt. Although they described the belt as “death lurking 70 miles up” it actually deflects high energy particles away from earth, meaning life can be sustained on earth. The satellite batteries powered the high-powered transmitter for 31 days, and after 105 days it sent it’s last transmission on May 23rd 1958. It still remained in orbit for 12 years, reentering the atmosphere over the pacific ocean on March 31st after 58,000 orbits.
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 22:02 UTC on March 1st 2018 the Second Atlas V launch of 2018 fired the 5,192kg GOES-S satellite into orbit. Launching from Space Launch Complex 41 at Cape Canaveral, FL, the AV-077 (the launch designation) was an Atlas V in 541 configuration. GOES-S, an A2100 series satellite built by Lockheed Martin, was separated 3.5 hours into the mission into a 8,215km x 35,286km x 9.52 deg Geosynchronous Transfer Orbit (GTO).
The second of a new generation of weather satellites for the United States, GOES-S follows in the footsteps of GOES-East, now renamed to GOES-16. A huge jump in satellite capability, the new set of satellites cover from eastern Japan all the way over to west Africa, as well as parts of the Arctic and Antarctic. They can detect storms faster, see lightning and even have sensors to detect solar storms. The satellites were commissioned by the National Environmental Satellite, Data and Information Service (NESDIS) who manage the National Oceanographic and Atmospheric Administration (NOAA) constellation of environmental satellites. For more images and information follow them on twitter @NOAASatellites.
There are versions of the livestream on Youtube, and a highlight reel on the ULA Youtube page. They are definitely worth a watch if you want more information from the engineers themselves.
