How 500 horses get to Mackinac Island each spring

6:01 pm

An evening pause: As noted at this website:

The island was America’s second national park (after Yellowstone National Park) for 20 years and has been the state of Michigan’s first state park. The island has had a ban on automobiles since the earliest days and still has the only highway in the nation where cars are banned.

Apparently, during the winter the horses are taken to the mainland for their benefit, and then returned in the spring in preparation for the summer tourism season. As this is the Friday of Memorial Day weekend, the start of the summer season, this seems most appropriate for tonight.

Northrop Grumman wins $45.6 million contract to launch Space Force weather smallsat

9:59 am

Northrop Grumman has won $45.6 million contract from the Space Force to launch a weather smallsat, using its Minotaur-4 rocket that was formerly a military ICBM.

The weather satellite, built by General Atomics, is part of an effort by the military to stop building its big expensive and continuously delayed weather satellites and instead buy the services from the private sector. This three year demonstration mission will prove whether General Atomics’ weather satellite can do the job. The Space Force has also contracted with Orion Space Systems to test its own weather satellite in orbit.

For Northrop Grumman, this contract helps keep its launch business alive while it awaits a new American engine for its Antares rocket, replacing the Russian engines it has previously depended on.

Satellite fuel company Orbit Fab signs Impulse to build part of its fuel depot

9:51 am

The satellite fuel company Orbit Fab, which is offering a way for satellites to get refueled on a regular basis based on a firm price schedule, has selected the orbital tug company Impulse to build part of its fuel depot in advance of a demonstration refueling mission for the Space Force.

The Space Force last year awarded Orion Space Solutions a $50 million contract for the Tetra-5 experiment. Three satellites will be stationed in geostationary orbit (GEO) where Impulse Space’s Mira orbital service vehicle will serve as a hosting platform for Orbit Fab’s fuel depot. “This demonstration will pave the way for future commercial orbital refueling services, as well as additional collaborative opportunities and missions between Orbit Fab and Impulse Space,” said Barry Matsumori, chief operating officer of Impulse Space.

The Tetra-5 satellites and the fuel depot will use Orbit Fab’s refueling port known as RAFTI, or Rapidly Attachable Fuel Transfer Interface. Impulse Space will provide hosting services such as power, communications, attitude control and propulsion for the fuel depot. The Tetra spacecraft will rendezvous and dock with the depot.

If successful, this mission will prove the viability of this refueling system, and encourage other satellite manufacturers to include RAFTI on their satellites.

NASA’s corrupt safety panel doubts Starliner is ready for its first manned flight in July

9:26 am

The head of NASA’s safety panel — which over the years has consistently missed the big safety issues while whining about things that did not matter — expressed strong doubts yesterday on whether Boeing’s Starliner manned capsule is ready for its first manned flight in July.

Speaking at a May 25 public meeting of the Aerospace Safety Advisory Panel, Patricia Sanders, chair of the committee, expressed skepticism that NASA and Boeing will be able to close known issues with Starliner in time for a launch currently scheduled for as soon as July 21.

“There remains a long line of NASA processes still ahead to determine launch readiness” for the Crew Flight Test (CFT) mission, the first crewed flight of the spacecraft with two NASA astronauts on board. “That should not be flown until safety risks can either be mitigated or accepted, eyes wide open, with an appropriately compelling technical rationale.”

This panel hasn’t the faintest idea what it is talking about, and should be ignored. It appears that NASA and Boeing are presently reviewing the capsule’s parachute system. Sanders however raised other issues which actually appear more designed to simply slow or even prevent the capsule’s launch.

The panel did the same thing during the development of SpaceX’s manned Dragon capsule, making irrelevant claims about paperwork and the safety of the company’s Falcon 9 fueling procedures that were ridiculous. Meanwhile, it has ignored much more fundamental numerous safety issues with NASA’s SLS rocket and Orion capsule, such as the agency’s plan to fly it manned using its capsule environmental system for the first time.

It is very possible that there remain serious safety issues with Starliner. I simply note that I would not rely on NASA’s safety panel to provide me an honest or educated appraisal of the situation.

Vulcan launchpad static fire engine test aborted

9:14 am

ULA engineers were forced yesterday to abort their first attempt to complete a launchpad static fire engine test of the first stage of the company’s new Vulcan rocket due to an issue with “the booster’s ignition system.”

[D]uring the countdown at Launch Complex 41 Thursday afternoon, ULA teams “observed a delayed response from the booster engine ignition system,” the company said in a statement. The issue meant that countdown procedures ahead of the ignition of two Blue Origin-built BE-4 engines at the business end of the company’s new rocket had to be halted.

The roughly 200-foot rocket will have to be rolled back into ULA’s nearly 300-foot protective Vertical Integration Facility for technicians to assess the booster’s ignition system.

It will obviously be necessary to attempt this static fire test again before attaching the rocket’s solid-fueled side boosters, which suggests the launch’s tentative target date in June is likely threatened.

These kinds of issues are not unexpected prior to a rocket’s first launch. ULA however is now paying for the three-plus year delay imposed on it by Blue Origin’s delays in delivering the BE-4 engines used in that first stage. These pre-launch tests had been planned for 2020, not 2023. Let us hope that ULA engineers don’t rush these tests now, because of those Blue Origin delays.

Ispace publishes results of its investigation into Hakuto-R1 lunar landing failure

9:05 am

Orbiter (LRO). Click for original blink image.

Ispace today published the results of its investigation into the failure of its Hakuto-R1 lunar landed to touch down on the moon successfully, stating that the cause was a software error which thought the spacecraft was closer to the ground than it was.

At the end of the planned landing sequence, it approached the lunar surface at a speed of less than 1 m/s. The operation was confirmed to have been in accordance with expectations until about 1:43 a.m., which was the scheduled landing time.

During the period of descent, an unexpected behavior occurred with the lander’s altitude measurement. While the lander estimated its own altitude to be zero, or on the lunar surface, it was later determined to be at an altitude of approximately 5 kms above the lunar surface. After reaching the scheduled landing time, the lander continued to descend at a low speed until the propulsion system ran out of fuel. At that time, the controlled descent of the lander ceased, and it is believed to have free-fallen to the Moon’s surface.

The company believes the software got confused when the spacecraft crossed over the rim of Atlas Crater.

The resulting crash produced the debris seen by LRO to the right.

Virgin Galactic completes first manned suborbital flight in two years

8:59 am

Virgin Galactic yesterday completed its first manned suborbital flight since July 2021, carrying six employees to about fifty miles altitude for about five minutes.

Virgin Galactic’s “mothership” aircraft, VMS Eve, took off from the runway at Spaceport America in New Mexico at 11:15 a.m. Eastern. The takeoff occurred more than an hour behind a schedule provided by the company the day before, but the company did not disclose the reason for the delay.

Virgin Galactic released VSS Unity at 12:23 p.m. Eastern. The spaceplane appeared to perform a nominal burn of its hybrid rocket engine before descending to a runway landing back at Spaceport America nearly 15 minutes later. Virgin Galactic said the vehicle reached a peak altitude of 87.2 kilometers — above the 50-mile altitude used by U.S. government agencies for awarding astronaut wings, but below the 100-kilometer Kármán line — and top speed of Mach 2.94.

The company did not live stream the event, in sharp contrast to the heavy coverage it always provided when Richard Branson was in charge. It now says it soon begin regularly passenger flights.

Rocket Lab’s Electron rocket lifts two more NASA hurricane monitoring satellites into orbit

8:58 pm

Rocket Lab today successfully used its Electron rocket to place the last two of NASA’s four-satellite Tropics hurricane monitoring constellation into orbit.

The first launch occurred about two and a half weeks ago, on May 7, 2023. Both launches were originally contracted to Astra, but when that company discontinued operations of its Rocket-3 rocket, NASA turned to Rocket Lab.

The leaders in the 2023 launch race:

34 SpaceX
19 China
7 Russia
5 Rocket Lab

The U.S. now leads China 39 to 19 in the national rankings, and the entire world combined 39 to 33. SpaceX by itself now trails the entire world, including American companies, 34 to 38.

Note that at this moment SpaceX and Rocket Lab are the only American companies that have launched. The established rocket companies, ULA and Northrop Grumman, have launches planned but none as yet, while two American companies have ceased operations, Astra (supposedly temporarily) and Virgin Orbit (permanently).

American freedom resulted in the competition in rocketry which has lowered costs but taken business from the established companies. Freedom has also caused the death of two companies, because the success that freedom brings also carries risks. Failure can happen, but the sum total of achievement is always greater than when competition is squelched.

South Korea successfully launches its Nuri rocket for the second time

12:43 pm

The new colonial movement: South Korea today successfully launched its home-built Nuri rocket for the second time, lifting off from a coastal South Korean spaceport and carrying eight smallsats.

This was South Korea’s first launch this year. The leaders in the 2023 launch race remain the same:

34 SpaceX
19 China
7 Russia
4 Rocket Lab

The U.S. still leads China 38 to 19 in the national rankings, and the entire world combined 38 to 33. SpaceX by itself now trails the entire world, including American companies, 34 to 37.

Hat tip to BtB’s stringer Jay for reminding me of this launch.

Nova Scotia spaceport gets another launch contract

9:55 am

Maritime Launch Services, which is building a spaceport in Nova Scotia and hopes to offer its own rocket services to put satellites in orbit, has obtained what it claims could be a $1 billion contract with an unnamed European orbital tug company.

The only two European orbital tug companies that closely fit the description provided by Maritime officials are D-Orbit or Exolaunch. The latter had had a contract with Virgin Orbit to launch as many as 20 of its satellites. Coming less than one day after Virgin Orbit’s assets were sold off, this announcement suggests Exolaunch has replaced Virgin Orbit with this deal.

Unlike other spaceports, Maritime isn’t merely providing a launch site for rocket companies. Instead the company will also launch smallsats itself, using either Ukraine’s Cyclone-4M rocket or a British-made startup rocket dubbed Skyrora.

Relativity and Impulse are now targeting ’26 launch window for 1st private mission to Mars

9:41 am

According to officials from the two companies, Relativity and Impulse have now delayed the launch date of their joint private unmanned lander to Mars from the ’24 launch window to the ’26 launch window.

The companies have also shared few technical details about the lander, but noted they plan to leverage designs and technologies developed for NASA’s InSight Mars lander, such as its heat shield. “We’re not trying to reinvent the wheel,” Brost said. “Doing a clean-sheet design of a lander is an insane, monumental engineering feat.”

Relativity is tasked with launching the probe, using its Terran-R rocket, which is under development and has its first launch scheduled in 2026. Impulse, which is building the lander, is at this point simply trying to develop its first small rocket engine. It appears therefore that this proposed Mars lander is designed mostly to make NASA willing to consider it when it starts hiring private companies to land probes on Mars. Its chances of launching in ’26 is quite small.

Spaceport startup launches small amateur rockets from ship

9:56 am

A company dubbed The Spaceport Company on May 22, 2023 launched two small amateur rockets from a ship in the Gulf of Mexico in order to demonstrate the logistics of such launches in advance of developing a floating launchpad.

The Spaceport Company, based in northern Virginia, launched on Monday 4-inch and 6-inch diameter rockets from a vessel about 30 miles south of Gulfport, Miss. The one-year-old company wanted to demonstrate its operations and logistics, which included getting approval from federal regulators, before developing larger floating platforms that would send satellites into orbit.

These offshore launches, as small as they were, were the first such ocean launches in U.S. history.

It appears that the company wants to offer an alternative launch option that might avoid the problems created by regulators in the UK that destroyed Virgin Orbit.

Launch of Sierra Space’s Dream Chaser now scheduled for six month window opening in August

9:47 am

After years of delays, Sierra Space’s first Dream Chaser reusable mini-shuttle, dubbed Tenacity, is now scheduled for launch during the six month mission to ISS of a crew scheduled for launch in August.

Dream Chaser’s first flight on a United Launch Alliance Atlas V rocket is expected while Crew-7 is aboard and two of those crew members, NASA’s Jasmin Moghbeli and JAXA’s Satoshi Furukawa, recently trained on it. JAXA and NASA formally announced Furukawa’s assignment to Crew-7 today. Furukawa, Moghbeli, ESA’s Andreas Mogensen and a Russian cosmonaut whose assignment has not been officially announced yet, are expected to launch in mid-August for a 6-month stay on the ISS.

The exact launch date within that mission has not yet been determined. It will largely depend scheduling, fitting it in with other launches to the station, assuming Tenacity’s construction is finished in time. That construction began in 2015, and has taken three to four years longer than first announced.

Bankrupt Virgin Orbit is dead, its assets purchased by a variety of different companies

9:34 am

After failing to find a single buyer for the whole company, Virgin Orbit is now officially dead as a company, its assets broken up during bankruptcy proceedings and purchased by several different companies.

Rocket Lab paid $16.1 million for Virgin Orbit’s main manufacturing facility in California, which it intends to use for developing its larger Neutron rocket. Stratolaunch paid $17 million for the company’s 747 airplane and related equipment. Launcher, a former rocket startup that is now owned by the space station startup Vast, paid $2.7 for the company’s test site in Mojave, California, which it plans to use for static fire engine tests of a rocket engine it is developing for sale to others. A liquidation company purchased other assets, while the various LauncherOne rockets under construction remain unsold.

It is essential the reasons for this failure are made very clear. The destruction of this company occurred because regulators in the United Kingdom prevented it from launching from within the UK for almost half a year, during which it could not perform other launches elsewhere and therefore earn revenue. It then ran very low on cash, and when the UK launch failed in January, the company no longer had the resources to weather to time necessary to complete the investigation, fix the problem that caused the failure, and resume launches.

For other rocket startups, it is very important to consider this story before committing to launching in the UK. where you will face major bureaucratic obstacles from its government. Until there is evidence that something has changed, it might be better to consider other launch sites.

Lunar Reconnaissance Orbiter spots Hakuto-R1 impact debris on Moon

9:38 am

Hakuto-R1 impact site, before and after
Click for original blink image.

NASA’s Lunar Reconnaissance Orbiter (LRO), scientists have spotted what they think is the impact debris produced when Ispace’s private lunar lander Hakuto-R1 crashed on the Moon on April 25, 2023.

To the right are two LRO images, the first at the top taken prior to Hakuto-R1’s landing attempt. The second at the bottom was acquired by LRO on April 26, 2023, the day after that attempt. The lettered arrows indicate four spots where the scientists identified changes between the two pictures. From the caption:

Arrow A points to a prominent surface change with higher reflectance in the upper left and lower reflectance in the lower right (opposite of nearby surface rocks along the right side of the frame). Arrows B-D point to other changes around the impact site.

According to the LRO science team, these changes suggest different pieces of debris, though it will take more analysis and more images under different lighting conditions to determine more precisely what they have found.

The presence however of four pieces strongly suggests that Hakuto-R1 hit the ground hard enough to break apart. Based on the initial data received during landing, it was thought the spacecraft had touched down softly but then was damaged by some unforeseen obstacle on the ground, such as a large boulder. The LRO image suggests instead that it did not touch down softly at all.

Air Force awards Ursa Major rocket engine development contact

9:13 am

The Air Force Research Laboratory (AFRL) has awarded the rocket engine startup Ursa Major a contract to develop two different rocket engines.

Under the contract, the Colorado-based firm will build and test a prototype of its new Draper engine for hypersonics, and further develop its 200,000-pound thrust Arroway engine for space launch.

…Under the AFRL contract, for which neither the lab or company provided a value, Ursa Major will also build a dedicated test stand for Draper and plans to hotfire the engine within 12 months.

Arroway, on the other hand, is a reusable liquid oxygen and methane staged combustion engine for medium and heavy launch vehicles. Ursa Major first announced development the 200,000-pound thrust engine last August, explaining that when clustered together, Arroway engines could replace the Russian-made RD-180 and RD-181, which are no longer available to US launch firms.

According to Ursa Major’s press release, the AFRL contract will allow further development of Arroway with a hotfire expected in 2025.

Ursa Major already has several contracts for its smaller Hadley engine, from the rocket startups Phantom, Vector, Astra, and the Air Force, and has built more than a hundred so far. The Arroway meanwhile is being developed as an American replacement for the Russian engines used by Northrop Grumman in its Antares rocket.

All in all, it appears Ursa Major is becoming a major challenger to Aerojet Rocketdyne, which in recent years had a lock on most government contracts for rocket engines. That lock resulted in very expensive engines that took years to build. The government (and others) are now finding someone else to provide this service at a better cost and far more quickly. We shall see whether Aerojet Rocketdyne responds to this competition properly, or goes the way of the horse carriage.

SpaceX files to join FAA as defendant in lawsuit trying to shut down Boca Chica

9:01 am

SpaceX on May 19, 2023 submitted a motion to become a defendant in the lawsuit filed by the Center for Biological Diversity (CBD) and others that demands its Starship/Superheavy launchsite at Boca Chica be shut down.

“SpaceX’s Starship/Super Heavy launch program hinges on the FAA’s review and licensing decision challenged here. If the Court were to rule in Plaintiffs’ favor, the FAA’s decision could be set aside, and further licensing of the Starship/Super Heavy Program could be significantly delayed, causing severe injury to SpaceX’s business,” the company said in the motion, which was filed on May 19.

The full motion can be read here [pdf].

SpaceX’s motion notes that it has followed all government regulations in the decade since it established its Boca Chica launch site, and invested more than $3 billion in doing so. The motion points out that “the FAA does not adequately represent SpaceX’s interests” and that the company must participate because the lawsuit will have direct financial impact on its business.

In other words, the big guns are now being hauled out against this lawsuit, which on its face is somewhat weak. We shall see if it can withstand the much more aggressive fight that SpaceX is certain to put up.

Indian company joins the high altitude balloon tourist race

9:23 am

A new company from India, Space Aura, is proposing to fly tourists on a high altitude balloon by 2025, joining the global competition that already includes two American balloon companies as well as one Spanish company.

Space Aura’s capsule, christened prototype SKAP1, will be tethered to a high performance ‘space balloon system’, complete with an enormous parachute. The capsule will accommodate six tourists and one pilot with ample leg room and comfortable walking space. It will be pressurised during flight and will have environmental control and life support systems that maintain oxygen, pressure, and temperature levels.

Even though passengers will not experience microgravity, they would still need to prepare before flying. Prior to the launch, which will be from Karnataka, Maharashtra, or Madhya Pradesh, the group of space tourists will undergo a week of basic physical training. The duration of the entire flight is expected to be about 5.5 to 6 hours. Tourists will ascend for about 90 minutes, spend an hour gazing out at the earth below, and begin their 90-minute descent with the balloon and parachute.

The two American companies, Space Perspective and World View, claim they will be flying tourists by 2024, while the Spanish company, Halo Space, is targeting 2025.

China launches two satellites yesterday, one for Macau

9:16 am

China yesterday used its Long March 2C rocket to launch two satellites into orbit, with one the first science satellite by Macau, designed to study the Earth’s magnetic field in conjunction with other satellites already in orbit.

No information that I could find was released about the second satellite. The launch, from China’s interior Jiuquan spaceport, dropped the rocket’s first stage somewhere in China. No word on whether it landed near habitable areas.

The leaders in the 2023 launch race:

34 SpaceX
19 China
6 Russia
4 Rocket Lab (with a launch scheduled for tomorrow)

American private enterprise still leads China 38 to 19 in the national rankings, and the entire world combined 38 to 31. SpaceX by itself now tied trails in total launches with the rest of the world, including American companies, 34 to 35.

SpaceX launches Axiom’s second commercial manned mission to ISS

2:47 pm

SpaceX today successfully used its Falcon 9 rocket to launch its Freedom manned capsule on its second flight, carrying four passengers on Axiom’s second commercial manned mission to ISS.

The Axiom crew included three paying passengers, one from the U.S. and two from Saudi Arabia, with the fourth crew member former NASA astronaut Peggy Whitson, now acting as Axiom’s commander. They plan to spend eight days docked to ISS. Making this commercial flight even more interesting is that the station already has a Middle Eastern commercial astronaut, from the United Arab Emirates. The Arab space race is clearing heating up.

The first stage was making its first flight, and successfully landed back at Cape Canaveral.

Were you aware this was happening? With my readers I expect so, but I am willing to bet that we are a very small minority. SpaceX has now made American manned spaceflight so routine almost no one pays attention.

The leaders in the 2023 launch race:

Starship prototype #25 is rolled to launchpad for static fire engine tests

10:02 am

Starship prototype #25 on the way to launchpad
Click for original image.

SpaceX yesterday evening rolled its 25th prototype of its Starship spacecraft to its suborbital launchpad at Boca Chica, as shown on the image to the right, for a planned static fire engine test of its six Raptor engines.

If all goes well, the company hopes to stack this prototype on top of the ninth prototype of Superheavy and complete the second test orbital flight of the entire rocket as early as June 15, 2023, with a launch window as long as six months according to the company’s FCC communications license application.

The actual launch date however remains very uncertain, for several reasons. The FAA must issue a launch license, and it won’t do that until it is satisfied the investigation into the first launch failure is complete. That launch approval will also likely be delayed because of the lawsuit against that agency for issuing the previous launch license.

The Moon as seen by Capstone
Click for original image.

The smallsat engineering test lunar orbiter Capstone has now successfully ended its primary mission, completing six months of operation in the near-rectilinear halo orbit that NASA’s Lunar Gateway manned space station intends to fly.

To put a final touch on that main mission, in May mission managers at the private company Advanced Space also completed two additional experiments. On May 3, 2023 they performed a close-fly of the Moon, using the spacecraft’s camera for the first time to take the picture of the Moon to the right.

Then, on May 9 Capstone successfully tested navigation technology in conjunction with NASA’s Lunar Reconnaissance Orbiter (LRO), also in orbit around the Moon.

During the May 9 experiment, CAPSTONE sent a signal to LRO designed to measure the distance and relative velocity between the two spacecraft. LRO then returned the signal to CAPSTONE, where it was converted into a measurement. The test proved the ability to collect measurements that will be utilized by CAPS software to determine the positioning of both spacecraft. This capability could provide autonomous onboard navigation information for future lunar missions.

The mission now enters its extended mission, planned to last at least a year.

NASA picks Blue Origin’s partnership for building second manned lunar lander

9:25 am

Artist's concept of Blue Moon
An artist’s concept of Blue Moon

NASA today announced that it has chosen the partnership led by Blue Origin to build a second manned lunar lander for its Artemis program.

Blue Origin will design, develop, test, and verify its Blue Moon lander to meet NASA’s human landing system requirements for recurring astronaut expeditions to the lunar surface, including docking with Gateway, a space station where crew transfer in lunar orbit. In addition to design and development work, the contract includes one uncrewed demonstration mission to the lunar surface before a crewed demo on the Artemis V mission in 2029. The total award value of the firm-fixed price contract is $3.4 billion.

The other partners in the contract are Draper, Astrobotic, and Honeybee Robotics.

This is NASA’s second contract for a lunar lander, with SpaceX’s Starship the first. The idea is to have two landers available from competing companies for both competition and redundancy, similar to the approach the agency has used for its manned ferry service to ISS, using SpaceX and Boeing. I wonder if NASA’s experience on the Moon will be similar to that ferry service, whereby only SpaceX so far has been able to deliver. The track record of Blue Origin suggests it will do about as poorly as Boeing has with Starliner.

Final assembly of Chandrayaan-3 begins for launch still targeting mid-July

9:24 am


Click for interactive map.

Engineers at India’s space agency ISRO have begun the installation of the payloads onto its lunar lander/rover, Chandrayaan-3, which is still targeting a mid-July launch.

The map shows the landing location (red dot) near the Moon’s south pole (indicated by the cross). Nova-C is Intuitive Machines private lander, now aiming for a late summer launch at the earliest. Luna-25 is Russia’s first lunar lander since the 1970s, and is also targeting a launch in July.

India’s first attempt, Chandryaan-2, to land a rover at this spot on the Moon failed in 2019. This new mission is essentially a re-do, except that it does not include an orbiter, since the orbiter from Chandrayaan-2 is still operational and can do the job.

All in all, it increasingly looks like the next six months will see a lot of new landing attempts on the Moon.

Student model rocket doubles altitude record

9:10 am

On April 16, 2023 students from the Embry-Riddle Aeronautical University launched a model rocket that more than doubled the altitude record for liquid-fueled model rockets.

The rocket reached an altitude of 47,732 feet, setting multiple records, including the highest undergraduate and collegiate amateur liquid rocket launch in the United States. It more than doubled the previous record of 22,000 feet.

Named Deneb after one of the brightest stars in the northern hemisphere, the rocket had a total burn time of 26.1 seconds, reaching a velocity of 1,150 mph (Mach 1.5).

ULA’s first Vulcan rocket returns to assembly building after fueling tests

9:22 am

After completing a tanking test, engineers have now moved ULA s first Vulcan rocket back to the assembly building for some additional work prior to the first wet dress rehearsal countdown and static fire test.

A ULA spokesperson said the company’s engineers “collected excellent data” during the May 12 tanking test, which mimicked a launch countdown with holds, readiness polls, and other milestones. “Based on the test, there are several parameters that will be adjusted prior to conducting the Flight Readiness Firing,” the ULA spokesperson said in a statement. “We are rolling back to the Vertical Integration Facility, where our access is better and the vehicle is protected to isolate and perform those adjustments.”

The static fire test will occur prior to attaching two strap-on solid-fueled side boosters, provided by Northrop Grumman, that are needed for the first launch. That launch is presently scheduled for sometime this summer, but first the static fire test has to take place successfully, with no issues, and these boosters need to be attached.
