Update: SpaceX scrubs its tenth Starlink assignment from Kennedy Space Center due to continuing hardware issues.

Launch fans are hoping the third time is a charm for SpaceX’s successive Starlink satellite mission.  The recycled Falcon 9 rocket is currently slated to lift off from pad 39 A at Kennedy Space Center now at 10: 54 AM. 

The Falcon 9 will fly 57 Starlink satellites along with 2 micro-satellites from Seattle based BlackSky, within the SpaceX rideshare program. 

In an effort to finance his ambitious goal of reaching Mars, SpaceX CEO Elon Musk is leaping into the broadband internet business using his Starlink satellite constellation. Connectivity will be provided by the satellites to places that are rural from distance.  Musk has said he expects to start service. 

If the current Starlink launch is successful, the constellation will number around 600 satellites in orbit.

The launching has been scrubbed June 26  since based on SpaceX that the”team needed extra time to get pre-launch checkouts, but Falcon 9 along with the satellites are healthy.”

Launch was scrubbed back on July 8 due to weather. 

The weather for the launch attempt is appearing about the same as Wednesday’s stopped launching noting storms that will develop in the late afternoon and early afternoon. In accordance with the 45th Space Wing, states are now 60 percent”go.” 

About eight minutes after liftoff, the Falcon 9 rocket’s first-stage booster will try a landing on the Of Course I Still Love You drone boat stationed in the Atlantic Ocean.

There is presently no backup date if today’s launch scrubs again but space fans won’t need to wait long for longer rocket activity.  SpaceX is prepping another Falcon 9 to launch South Korea’s first dedicated military satellite in Cape Canaveral Air Force Station.

If it finally gets off the floor Saturday in 8 a.m. PT (11 a.m. local time) as planned, the Falcon 9 rocket’s payload includes the very first batch of the company’s broadband satellites equipped with a sunshade to lessen their brightness. 

Since Elon Musk’s company started launching the small satellites over a year before, astronomers and other observers have been surprised and even disturbed by the amount of sun the orbiting routers reflect, frequently interfering with scientific observations. 

Musk and SpaceX have been operating with major astronomical associations on the problem and vowed to fix the problem since they ramp up plans to establish thousands of those satellites in the next several years.

Are SpaceX Starlink satellites destroying the night sky?

Initially, SpaceX tried starting a so-called”darksat,” which was basically a Starlink satellite with a dark coating, but the results from this strategy were mixed. Next the firm developed and tested a deployable sunshade that it requires”VisorSat.”

One VisorSat was established earlier this month to examine the new technician, and the next launch will take the first batch to be fully shaded. 

The mission will come on the heels of a June 30 Falcon 9 rocket launching , which divides a new GPS satellite to the US army. After sending a satellite to space the SpaceX landing followed that. 

Saturday’s launch is a rideshare, which means room was created for a pair of Earth-observing satellites for the company BlackSky.

It is possible to watch the launching via the livestream below, which generally starts about 15 minutes before liftoff.

SpaceX targeting this weekend for 10th Starlink launching

Launch scheduled for 10: 54 a.m.

KENNEDY SPACE CENTER, Fla. — Hopefully, the next time will be the charm for SpaceX’s second Starlink launch. The company said it is targeting late Saturday morning to ship its up 10th batch of internet-beaming satellites along with a few other ride-sharing spacecraft.

The brand new Falcon 9 launch window has been scheduled for 10: 54 a.m. from Kennedy Space Center 39A. The previous effort on Wednesday was rained out roughly 10 minutes before liftoff.

It’s Florida in July which means weather could be a factor this weekend. In accordance with Air Force weather officials, there’s a 60% chance of favorable weather for Saturday’s start window.

“On Saturday, there will be northwest to southeast moving showers and showers that will develop in the late afternoon and early afternoon across Central Florida,” according to this 45th Weather Squadron forecast. “While the majority of this action will probably be in the afternoon, some storms and showers can’t be ruled out during the launch window due to the surface trough and weak impulses aloft.”

Due to the most recent prediction, cloud cover and potential lightning producing weather would be the key concerns.

Here are five things that you need to understand for the launch when it does occur:

  • What’s on board: 57 Starlink communications giants and 2 spacecraft for BlackSky Global. BlackSky bought a ride through Spaceflight Inc., a company that arranges transportation for spacecraft and payloads to space.
  • Backup window TBD: In the event of a delay, a backup window has not been released.
  • Landing data: About eight minutes after liftoff, the Falcon 9 rocket’s first-stage booster will target an automatic landing the Of Course I Still Love You drone ship stationed in the Atlantic Ocean.
  • Starlink internet: After this launch, SpaceX will have established nearly 600 Starlink satellites. The target is to make a network of satellites to generate high-speed net anywhere in the world. SpaceX has to say when the net will go live but lately the company launched a site where people can sign up to get updates on service availability. According to that website, Starlink is targeting service at the Northern U.S. and Canada in 2020.
  • Astronomy impacts: SpaceX heard opinions from the research community regarding the shear quantity of Starlink satellites and possible disturbance in astronomical observations and has worked to address those issues. For this launch all of the Starlink satellites are equipped with a visor that can be set up to block sunlight from hitting on the brightest spots of their spacecraft. SpaceX claims this will help stop the satellite from interfering with astronomical observations and reflecting sunlight down to Earth. The company also previously attempted a darkening technique on one of those satellites that decreased its reflectivity by about half, based on SpaceX.

Check back throughout the week along with the countdown for updates on the launching.

SpaceX Falcon 9 landing leg accidentally dropped during retraction attempt

SpaceX has accidentally dropped one of its newest Falcon 9 booster’s landing legs during a retraction attempt in Port Canaveral while crews worked to prepare the rocket for transport.

Falcon 9 booster B1060 safely arrived in Port Canaveral, Florida on July 4th after a flawless June 30th launch debut, delivering the US military’s GPS III SV03 navigation satellite to an accurate orbit and becoming the first SpaceX rocket to launch and land as part of an operational US military mission. The major landing milestone was supported by drone ship Just Read The Instructions (JRTI) as part of its second East Coast recovery mission ever after an ~8000 km (~5000 mi) journey from Los Angeles and months of slow and steady upgrades.

Thankfully, despite the mishap caught on camera by diligent, unofficial observers, things appeared to work out just fine for booster B1060 as crews threaded recovery operations between bouts of disruptive Florida weather.

Based on video of the accidental leg drop captured by US Launch Report on July 7th, the most obvious conclusion is that operators either failed to release tension on a winch line or some kind of hardware/software/sensor failure unintentionally over-stressed the line. Regardless, around the same time as Falcon 9 or its ground operators were likely commanding the landing leg latch closed, one or both of the lines attached to the top of the retracting leg snapped, causing it to very quickly redeploy as gravity pulled it back to earth.

Almost certainly by design, nobody was underneath the ~1000 kg (~2200 lb) landing leg during retraction, and a small stand used to prop up the leg for winch line installation seems to have been moved out of the line of fire as part of the process. As a result, when the leg was accidentally released, it simply fell onto drone ship JRTI’s flat, steel deck under its own weight. Most importantly, nobody was (visibly) injured or at risk of injury

Jump to ~3: 45 to catch one of SpaceX’s 2018 landing leg deployment tests on a recovered booster.

The landing leg’s impact and aftershock looks undeniably harsh in the footage but the reality is that SpaceX has already performed almost identical tests (albeit intentionally) on recovered boosters while leg retraction was still in development. Captured in the video above, B1049’s September 2018 leg retraction and deployment test appeared to be marginally gentler than B1060’s accidental leg smack, and B1049 went on to complete four more orbital-class launches without issue. That still ignores the fact that Falcon 9’s landing legs are designed to withstand extremely rough landings of entire ~30 metric ton boosters traveling up to several meters per second (~5 mph) – vastly more force than a single landing leg can exert on itself with gravity as the only input.

(Richard Angle)

Confirming those suspicions, SpaceX ultimately got back on the saddle after a few slight weather delays and successfully retracted all four of B1060’s landing legs without issue. The once-flown rocket was quickly broken over (referring to the process of lowering it horizontally) and installed on a custom transporter, which will soon move it from Port Canaveral to a nearby SpaceX hangar (likely Pad 39A’s) to prepare for its next launch.

SpaceX scrubs Starlink v1.0 L9 Assignment

SpaceX was set for their inaugural launching of operational Starlink satellites, along with 2 satellites for BlackSky’s Earth monitoring constellation, on Wednesday, July 8 (11: )’m EDT / 15: 59 UTC).  However, regardless of the weather forecast issued from the 45th Space Wing the day before launch showing a 60% chance of acceptable weather, the states dropped ahead of T-0 causing a clean wash. An original backup date of Friday, July 10, is now in question since SpaceX says they’re working to set a new launch date.

This mission was previously scheduled for Friday, June 26, but the flight was scrubbed around three hours ahead of liftoff when SpaceX tweeted that they had more time for pre-launch checkouts. 

In the meantime, SpaceX successfully established a GPS satellite for the U.S. government on June 30 and is preparing to get as many as three more launches in July.  Upcoming launches later this month include a communications satellite for the South Korean authorities around July 14, a 2nd synthetic aperture radar monitoring satellite to the Argentinian authorities around July 25, and also a second pair of Starlink satellites.

This will be the fourth launching in six weeks for SpaceX, and the eleventh SpaceX orbital launch this season.

This flight will use Falcon 9 booster 1051.5 (the fifth flight of serial number 1051). This well-traveled booster has flown out of all three of SpaceX’s launch pads and will be trying its fourth landing on the drone boat Of Course I Still Love You, since it did during flights of Demo-1 for NASA’s Commercial Crew Program, Starlink v1.0 L3, and Starlink v1.0 L6. After launch Canada’s RADARSAT Constellation Mission, it has also landed at LZ-4 on Vandenberg AFB.

Rideshare adapter plate for use on Starlink paths ) It may hold two 28″ x 28″ x 40″ satellites, or one 42″ x 48″ by 60″ satellite. Picture from SpaceX Rideshare Payload User’s Guide.

The main payload for this assignment is a pair of 57 satellites to the Starlink online constellation.  Stack is a rideshare jack.  This rideshare adapter’s plan, that may hold two BlackSky sized tanks, allows it to take the place of a single Starlink satellite.  If necessary two of the rideshare adapters can be utilized, as was performed for its rideshare of three Planet SkySats on the prior Starlink launch.

This is going to be the first flight using the full load of satellites using deployable sun visors to reduce reflections from the antennas.  It’s estimated that this will make the satellites imperceptible to the naked eye when they are in their usable orbit, and reduce the brightness of the satellite streaks.  The visors are designed to achieve those goals without inducing additional heating of the satellites which can result from just making them darker.

BlackSky, a branch of Spaceflight Industries, is a ground observation firm that combines data from multiple sources, such as their own satellites, other satellite operators, and societal media platforms to give intelligence to their customers.  They’re starting an expansion of the constellation from four to sixteen satellites.

The sixth and fifth satellites in the BlackSky constellation, which every mass 55 kg, are the initial satellites manufactured by LeoStella, a joint venture of Spaceflight Industries and Thales Alenia Space.  Four BlackSky satellites are scheduled to launch on a Indian SSLV rocket later this season, and the firm hopes to launch another six on various missions through ancient 2021.

Only two BlackSky satellites are sent to SSO orbits which give a perspective of the whole globe.  The remainder of the sixteen satellites are going to mid-inclination orbits which will allow more regular observations of highly populated regions. The rideshare was organized by Spaceflight Inc., a former branch of Spaceflight Industries that was sold so the firm could concentrate on their BlackSky branch.

Here is the second of what is expected to be three consecutive rideshares on Starlink flights.  Planet launched three of the SkySats and contains manifested on another mission that’s expected to launch.  A market in the market that is rideshare fills by providing mid-inclination orbits with flights for passengers who may perform their orbit increasing from the Starlink installation orbits that are reduced.  While recent Starlink assignments have deployed to an altitude of approximately 200 x 380 km, pre-mission release data on CelesTrak reveals this assignment is targeting a higher deployment orbit round 388 x 401 km.  The growth in altitude might make it easier for the BlackSky satellites to reach their orbits.

SpaceX has also booked many clients for upcoming dedicated rideshare flights to Sun Synchronous Orbit, which will deploy at greater altitudes.

Devices which appear to be prototypes of the Starlink user terminal have been seen along with another antennas in Starlink gateway locations in Boca Chica, Texas and Merrillan, Wisconsin.  These consumer terminals will be crucial to the success of this Starlink network.

SpaceX board member Steve Jurvetson recently tweeted that the company’s board had an opportunity to try the user terminals in the business headquarters in Hawthorne.  The devices seem to use a Power over Ethernet (PoE) cable to get their power and data link.

SpaceX continues to make progress setting up its network of gateways for the Starlink system. Five new gateways are being inserted in the Northwest and North Central U.S. with locations in Northern California, Idaho, Minnesota, Montana, and Washington. From the Southeastern U.S., previously filed gateways in Tennessee and Florida were eliminated while new locations have been added in Georgia and Alabama. In the Southwest a place was added in Arizona. This brings the amount of U.S. Ka-band gateway locations to 32.

Prior to this v1.0 L9 launch, SpaceX has established 478 of the model 1.0 Starlink satellites towards the first deployment of approximately 1500 satellites.  Some of those have experienced issues after launch, with five now lowering their orbits and also a few more being deorbited already.  It appears about 460 of the 478 previously launch satellites are operational.

SpaceX is preparing to begin beta testing that the Starlink service in the coming months as the satellites from the initial seven launches of v1.0 satellites are utilized to fulfill 18 evenly spaced orbital planes.  Following the satellites from 12 starts of their v1.0 satellites reach their operational positions late in the calendar year, populating 36 of the 72 orbital planes at the first installation, SpaceX hopes to commence service in the northern US and southern Canada.

The next cartoon shows Starlink satellites dispersing out following launch since the beginning of 2020.  Each launch has divided its approximately 60 satellites into three orbital planes, which drift apart from each other in a lower parking orbit before the tanks have been increased to their operational altitude of 550km) The satellites in each plane spread out to evenly circle the planet once reaching the elevation that was right.

The Falcon 9 rocket with its payload connected was lifted into the vertical position in LC-39A late in the morning on Wednesday, June 24, in preparation for its static fire test.  The test was performed that evening at 6: 30pm EDT.

The launch countdown will formally commence in the T-38 minute mark on Thursday afternoon when the launch director will survey the assignment teams to proceed into propellant loading operations. When the”go” is given, chilled RP-1 gas will flow to both phases of the Falcon 9 launch vehicle at 35 minutes to liftoff, along with liquid oxygen (LOX) loading into the first phase. LOX loading onto Falcon 9’s second stage begins at T-16 minutes.

At T-7 minutes prior to liftoff, the liquid oxygen pre-valves over the nine Merlin-1D first phase engines open, allowing LOX to flow through the engine plumbing and condition the turbopumps for ignition. This practice is called”engine chilling”, and can be used to prevent thermal shock which could damage the motors upon startup.

A Falcon 9 is going vertical in LC-39A. High likelihood of static fire afterwards today as this are the normal cadence if one were to happen. We’ll keep eyes on the shore for updates on the 10th batch of Starlink satellites awaiting launch tomorrow. #Starlink #SpaceX pic.twitter.com/rAvo3QlSzP

In the T-1 second markers, the Falcon 9’s onboard flight computers operate through final checks of the car’s systems and finalize tank pressurization prior to flight. The launch manager gives a final”go” for launch at T-45 seconds.

The two Merlin-1D engines on the first stage ignite at T-3 seconds, with liftoff taking place in T-0 following a fast final test by the onboard computers to verify that all systems are operating nominally.

After lifting off from LC-39A, the Falcon 9 pitches downrange since it accelerates towards orbital velocity. At around a moment and 12 minutes into the flight, the car moves through the area of maximum aerodynamic pressure, or”Max-Q”. During this portion of flight, the mechanical stresses on payload and the aircraft are in their highest.

The two Merlin-1D engines on Falcon 9’s first stage continue to burn until about T+2 minutes and 33 seconds, at which point they shut down in an event called MECO, or Main Engine Cutoff. Stage separation occurs soon afterward, with next stage Merlin Vacuum engine ignition occurring in the T+2 minute 43 second mark. Upon motor startup, the second stage will continue to carry all 60 satellites to some low Earth orbit, with an inclination of 53 degrees.

The 5-meter payload fairing home the payloads through the first phases of launching separates at approximately 3 minutes and 24 seconds into the flight. Both halves of the fairing descend back to Earth to be recovered by GO Ms. Tree and GO Ms. Chief, SpaceX’s fairing recovery vessel duo. The retrieval ships that are fairing did not have their big catch nets when they left port. SpaceX may be intending to scoop the fairing halves out of the water as they have on several missions that are recent.

While Falcon 9’s second stage and the payloads continue to press onward to orbit, Falcon core B1051.5 will return to Earth to conduct a propulsive landing the droneship”Of Course I Still Love You”, stationed approximately 630 km (391.4 miles) downrange from the launch website.

The first phase will execute an entry burn that ends in 6 minutes and 40 minutes to the flight, so as to slow its descent and develop its own trajectory into the droneship. The final landing burn will take place shortly around the 8 minute mark, with B1051.5 touching down softly on the deck of OCISLY below the electricity from one Merlin-1D engine 8 minutes and 24 minutes following liftoff.

The Merlin Vacuum engine on Falcon 9’s second point will close down for the first time at 8 minutes and 51 seconds into the flight in an event known as SECO-1, or Secondly Engine Cutoff.  After coasting for almost 40 minutes, then the second phase will relight in the T47 minute 18 second mark for a three second burn to raise the perigee into a circular orbit.

Just over an hour into flight that the BlackSky satellites will be released first from the cover of the payload heap.  The first BlackSky satellite will separate at the +1 hour minute 32 minute markers, followed by the next satellite at T+ 1 hour 6 minutes also 47 seconds.  After giving the BlackSky satellites some opportunity to drift off, the Starlink satellites will deploy in the +1 hour 32 minute 54 second mark.

After deploying all of the payloads, the second phase is expected to light its engine one more time for a deorbit burnoff, splashing down in the ocean south or west of Australia on its second orbit.

View SpaceX launch its latest batch of Starlink satellites, with two hitchhiking spacecraft

Only a week later starting a GPS satellite to its Space Force, SpaceX is back with a different launch of its internet-beaming Starlink satellites. The company’s Falcon 9 rocket is slated to shoot off from Cape Canaveral, Florida, today, launching 57 Starlink spacecraft and two hitchhiking Earth observation satellites from operator BlackSky.

The flight is the most up-to-date in SpaceX’s ongoing quest to flesh out its projected gigantic Starlink constellation, aimed at providing broadband internet connectivity in distance. The business has permission to launch almost 12,000 Starlink satellites in the Federal Communications Commission, a swarm of spacecraft that will beam net coverage to each point of the world. After this launch, SpaceX will have started 595 of its Starlink satellites (though at least one has come out of orbit, even though a few others have failed since making it into distance ).

Now’s assignment is the next Starlink launch to include another business’s satellites along for the ride. Typically, SpaceX has launched its own Starlink probes in batches of 60, all independently. But on a previous launch in June, SpaceX launched 58 Starlink satellites and three miniature imaging satellites in the company Planet. A broker that finds room for satellites launches, the company Spaceflight, arranged to fly on this mission. SpaceX includes its own program to organize ride-shares on its Falcon 9 rocket, as it did with all the current Planet ride-share, working with customers.

The Starlink satellites moving on today’s launch will sport a relatively new feature, also. They are equipped with a visor, called a sunshade, designed to avoid the light of the Sun from reflecting from the most shiny parts of their satellites the antennas. The target is to reduce the overall brightness of the Starlink spacecraft while in orbit so that they seem as dark as possible. SpaceX already launched one of those sunshades on a previous Starlink flight in early June. This is the first launch where the visor will be carried by the whole fleet.

SpaceX’s new sunshades are an immediate response to concerns which were raised by the astronomy community about Starlink. After the first launch of the satellites of SpaceX, astronomers discovered exactly how the spacecraft appeared in the skies, and scientists climbed stressed that a huge constellation of glistening satellites would hinder their observations of the Universe. To observe celestial objects, astronomers rely on taking images of the night sky — and a bright streak that may ruin an observation is left by a satellite.

Following discussion with top novelty classes, the sunshade is the most recent solution SpaceX has develop. The company tried coating among its Starlink satellites in early January to make it appear darker; this alternative didn’t dampen the vehicle enough to allay everyone’s fears. More changes may be on the horizon, also, such as changing the way the satellites are oriented once they attain their final orbits.

SpaceX’s Falcon 9 is famous for liftoff in 11: 59AM ET from the organization’s launchpad at NASA’s Kennedy Space Center in Florida. SpaceX is utilizing one of its rockets for the mission, a Falcon 9 which has flown to space and back four times before. The rocket will try to land on one of the drone ships of SpaceX at the Atlantic following the launch , possibly enabling the vehicle to fly after now for the time. Back in June, SpaceX set a new record of landing the exact same Falcon 9 for a fifth time after a flight; the feat could be repeated by the company today.

If all goes well, the two BlackSky satellites will deploy first, just over an hour after takeoff. The Starlink satellites will subsequently deploy approximately 30 minutes after that. Weather is somewhat iffy, together with just a 60 percent likelihood that conditions will be favorable for flight. If SpaceX can launch today, the organization’s live stream is set to begin about 15 minutes before takeoff.

SpaceX could send NASA into Jupiter’s Possibly habitable moon Europa

This NASA illustration shows the Europa Clipper above Europa, with Jupiter in the background.


NASA/JPL-Caltech

A Falcon Heavy, or another large SpaceX rocket, could transmit NASA’s planned Europa Clipper assignment to the freezing Jupiter moon Europa, which hides a subsurface ocean many scientists believe may be in a position to support alien life

A draft of a congressional appropriations bill released Tuesday opens the door for Elon Musk’s rocket company, or possibly a competitor like Jeff Bezos’ Blue Origin, to provide the ride that will send an orbiter to the Jovian system by 2025 and a lander to Europa by 2027.

“The National Aeronautics and Space Administration will use the Space Launch System, when available, as the 10 launch vehicles for your Jupiter Europa assignments,” reads the draft bill in the House Appropriations Committee. 

Those two words –“if available” — are fresh. In the past, Congress has tied cash for the Europa mission to some requirement that NASA use its Space Launch System. However SLS has been behind schedule and more than budget for years now. And SpaceX has been lapping NASA rocket development program lately, together with the debut of the Falcon Heavy and its larger Starship’s ongoing progress. 

SLS is proving to be far more expensive than what SpaceX can offer, and it’s not even clear it will be ready to go by 2025 at this stage. 

The bill also provides over $400 million for NASA to create up the Europa orbiter.

Of course, this is merely a start in the budgetary procedure. Congress will continue for what and to negotiate conditions and the actual amounts of just how much NASA will actually receive. Still, this very small shift in an early record is an important acknowledgement that sticking with SLS might not be practical if the rocket will not be ready in time for a launch when 2024.

The same bill also allocates funds for NASA’s Artemis assignment to return astronauts to the moon, even though it provides less than half of what the White House has asked for. 

The Trump administration has set a Aim of sending the first woman astronaut to the surface of the moon by 2024, a goal that many inside the space industry are skeptical can be achieved, especially without the full support of Congress and its pocketbook.

SpaceX first tried to launch this assignment back on June 26 but stood down a couple hours prior to the projected launch, citing the need for additional time to conduct pre-launch checkouts.

The launching of the satellites will bring SpaceX’s Starlink constellation to very nearly 600 complete spacecraft from low-Earth orbit.  And these are not small CubeSats–all the Starlink satellites weighs 260kg and has its own on-board propulsion system.

Because SpaceX plans to launch tens of thousands more of those satellites as it builds out a constellation of beacons in low-Earth orbit to provide global Internet service from space, astronomers have understandably begun to raise concerns. They fear both about the nighttime skies for backyard astronomers, as well as observatories in Mauna Kea, Chile, and elsewhere.

SpaceX has sought to address the problem, first by alerting the satellites to make them reflective. Now, the business is taking a step, creating a radio-transparent foam that will flip out from the tanks and prevent reflection.

“This visor lays flat on the chassis during launching and deploys through satellite separation from Falcon 9,” the company stated. “The visor prevents light from reflecting from this diffuse antennas by blocking the light from hitting the antennas altogether. Does this approach avoid the thermal effects from surface darkening the antennas, but it should also have a larger impact on brightness decrease ”

All the 57 Starlink satellites on board the Falcon 9 rocket will carry these”visor” sats for the very first time.

This will be the third time SpaceX has launched a Falcon 9 first period five times–this booster began its career with the Demo-1 assignment in March 2019 and has since spanned three additional missions. The business will seek to recover this booster on the Of Course I Love You droneship. The webcast below must start about 15 minutes before liftoff.

SpaceX Falcon 9 rocket to kick off Active month of launches with 10th Starlink mission

A Falcon 9 rocket is set to kick off a busy July of launches with SpaceX’s successive Starlink satellite assignment and second Starlink rideshare, while also (ideally ) solidifying Falcon 9 reusability.

For Falcon 9 booster B1051, the Starlink V1 L9 mission is going to be its fifth launch, which makes it the third SpaceX rocket to fly five different orbital-class missions. If B1051 handles to successfully land aboard drone boat of Course I Love You (OCISLY) some 630 km (~390 mi) from the coast of Florida, it will also become the second Falcon 9 booster to start and land five times in a row.

Starlink-9 is just one of four separate launches SpaceX has scheduled this season, after a ~10-day delay that prevented June 2020 from getting the organization’s first four-launch month. The mission will be the Starlink launch this year, potentially leaving SpaceX 40percent of the way to some 20-launching yearly target approximately 52percent of the way throughout the year.

If effective, Falcon 9 B1051’s fifth launch and landing is likely to produce the booster just one of just two to have achieved the feat and lived after Falcon 9 B1049 finished its fifth launching on June 3rd, 2020. Back on March 14th, Falcon 9 booster B1048 technically became the first SpaceX rocket to successfully complete five orbital-class launches, although a very rare search-engine engine collapse came close to prematurely ending the mission and fully precluded an effective landing.

65 days following the rocket returned to port, B1051 is envisioned here shortly before its launch has been delayed from June 26th to July 8th. (Richard Angle)

SpaceX returned into flight barely one month later when Falcon 9 booster B1051 launched for the fourth time in service of the Starlink-6 mission, a strong indication that B1048’s engine failure was really brought on by a mistake during refurbishment and not a design defect. Ever since then, SpaceX has finished five assignments, passing landmarks after an operational satellite launch for the US military like Crew Dragon’s inaugural NASA astronaut launching and Falcon 9 landing.

Starlink-9 isn’t quite as radical but it pushes SpaceX’s Starlink launches into the double-digits only 14 weeks when they started. Excluding the first Starlink v0.9 satellites SpaceX started in May 2019, the business is going to have technically finished nine Starlink v1.0 starts in under eight months when L1 V9 goes off without a hitch after today. All ~530 of those satellites may technically be counted on to one day serve high-quality internet to customers nearly anywhere on Earth, while it is unclear if the ~55 v0.9 satellites still in orbit could ever serve within the commercially usable constellation.

Starlink-9 will be SpaceX’s second Starlink rideshare and will be set to take two LeoStella-built BlackSky Earth imaging spacecraft into orbit (literally) on top of 57 Starlink v1.0 net satellites. While the ~$2M in earnings SpaceX probably generated with the rideshare does not come close to recouping the ~$25M spent each Starlink launch, the accumulative value of 10-15% savings on hundreds or dozens of launches will be far more substantial than it may seem at first glance.

No matter Falcon 9 B1051, 57 Starlink satellites, and also two rideshare passengers are scheduled to lift off from Kennedy Space Center (KSC) Launch Complex 39A no earlier than (NET) 11: ) am EDT (15: 59 UTC) on July 8th. As usual, SpaceX will offer live coverage of the launch beginning around 15 minutes before liftoff.
