Update on SpaceX’s work leading to next Starship/Superheavy test launch

10:29 am

Link here. A static fire engine test program has begun for Starship prototype #25, which will fly on top of a Superheavy prototype. Also, work on the launchpad, badly damaged by the first test flight in April, has proceeded quickly.

During the first integrated test flight of Starship, Super Heavy Booster 7’s 30 working engines dug a sizable hole under the OLM [Orbital Launch Mount] during liftoff. The first images of it pictured a dramatic scene and pointed at some tough repair work ahead for SpaceX teams. Over the last two months, the hole was covered and reinforcements have been installed deep into the ground to strengthen the soil.

More recently, teams have been installing several tons of rebar underneath the OLM. While some rebar remains to be installed, as seen from aerial pictures captured by NSF, this work is expected to be finished soon and should be followed by a convoy of concrete trucks to fill up the pit. SpaceX will then install water-cooled steel plates over this concrete which will help support them and serve as an anchor for them.

The update also describes the numerous additional prototypes SpaceX is building at Boca Chica for further flight tests. It also notes this disturbing fact about the company’s planned Starship/Superheavy launch facility in Florida:

Work on the second set of tower sections, chopsticks, carriage system, and QD arm at SpaceX’s Roberts Road facility has come to a halt. Contractor equipment has visibly disappeared and other construction equipment has been removed. The Florida Mega Bay parts have also made their way to Starbase, becoming the second Mega Bay at the Texas facility. The two big cranes that were previously at Roberts Road were also moved to Starbase to aid in the construction of that new Mega Bay.

On top of this, SpaceX has changed the use of the building previously thought to be the factory for Starship sections. This facility is now being used to process Starlink payload integration with Falcon 9’s fairings.

This slow down is probably because NASA has forbidden Starship/Superheavy launches from this launchpad because it is near the launchpad SpaceX uses for NASA’s manned missions. The agency wants SpaceX to be able to launch Dragon from its other more distant pad, and that work needs to be completed first before the Starship/Superheavy pad can be used.

More direct images released of exoplanet 87.5 light years away

9:56 am

Keck images of exoplanet over time

The Keck Observatory in Hawaii has now released its own image of the exoplanet AF Leporis b, following up the images produced by the Very Large Telescope (VLT) released in February.

The direct images Franson’s team captured revealed that AF Lep b is about three times the mass of Jupiter and orbits AF Leporis, a young Sun-like star about 87.5 light-years away. They took a series of deep images of the planet starting in December 2021; two other teams also captured images of the same planet since then.

What make the Keck observations most interesting is that they captured over time the motion of the exoplanet as it orbited its star. The two images to the right show this motion.

The paper, available here, was published today in Astrophysical Journal Letters. This particular star also has a debris disk surrounding it, suggesting it is a young solar system still in the process of forming. From the paper’s conclusion:

AF Lep joins other young planet hosts with debris disks such as β Pic, HR 8799, HD 206893, and HD 95086, reinforcing indications of a higher frequency of long-period planets orbiting stars hosting debris disks.

Startup orbital tug company experiences technical issues on demo flight

9:36 am

The first test rendezvous and docking of two smallsats built by the startup orbital tug company Starfish Space and space station startup Launcher/Vast are facing significant technical issues because both spacecraft are spinning in an unexpected manner.

Soon after Orbiter SN3 separated from the Falcon 9 upper stage, it experienced an anomaly that set it spinning at a rate on the order of one revolution per second, far outside the bounds of normal operating conditions.

By the time Launcher’s team made contact with Orbiter, fuel and power levels were critically low — and the team made an emergency decision to deploy Otter Pup immediately. In a joint statement issued today, Launcher and Starfish Space said that quick action “gave the Otter Pup mission a chance to continue.”

With assistance from Astro Digital and ground station partners, Starfish’s team contacted Otter Pup and determined that it was generating power — but was also spinning because of the circumstances of its emergency deployment.

The plan had been to deploy Otter Pup and have it rendezvous and then dock with Orbiter, demonstrating the maneuverability of both spacecraft as well as their docking equipment. The spinning now threatens the company’s ability to do this. Over the next few months engineers will make attempts to slow the spinning of Orbiter, but it is unlikely a docking can now be attempted.

Intelsat and SES end negotiations to merge

9:27 am

In a very short press release, the Luxembourg-based satellite company SES today announced that it has broken off negotiations to merge with the satellite company Intelsat. The full text:

SES announces today that discussions regarding a possible combination with Intelsat have ceased. On 29 March 2023, SES had confirmed that the company engaged in discussions with Intelsat and that there could be no certainty that a transaction would materialise.

It appears the two companies could not settle differences on a number of points, and according to this article Intelsat decided to end negotiations yesterday.

There has been a trend among the established satellite companies to consolidate and merge, faced with the stiff competition from the new satellite constellations of Starlink and OneWeb. It is very possible that both of these companies will either revisit the idea of this merger, or begin negotiations with other established satellite companies.

Ecuador becomes 26th nation to sign Artemis Accords

9:20 am

In a ceremony yesterday in Washington, Ecuador became the 26th nation to sign the Artemis Accords, a bi-lateral agreement with the United States that was designed during the Trump administration to act as a work around to the limitations to private enterprise in space created by the Outer Space Treaty.

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Adding third world nations to the alliance strengthens it, but it is really the clout of major space players like France, Luxembourg, the UK, the UAE, Italy, and Japan that gives the United States a great deal of leverage in establishing future space legal policy, assuming the alliance is used as originally intended. Considering however the Biden administration’s general hostility to the private sector and freedom, it is unclear if that will be the goal.

ULA launches Delta-4 Heavy rocket on next-to-last flight

9:02 am

Early this morning ULA successfully place a National Reconnaissance Office classified surveillance satellite into orbit, using its Delta-4 Heavy rocket lifting off from Cape Canaveral.

This was ULA’s its first launch in 2023. At the start of the year, the company’s manifest listed ten launches. Whether is can complete that manifest in the remaining six months is questionable, considering it has rarely managed a launch pace exceeding one launch per month in its entire history.

This launch was also the next-to-last for the Delta-4 Heavy. ULA is retiring that rocket and replacing it with the still-not-flown Vulcan rocket. The plan had been for there to be an overlap in use as one was retired and the other was initiated. That has not happened.

The leaders in the 2023 launch race remain the same:

42 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 48 to 24 in the national rankings, and the entire world combined 48 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 42 to 40.

Greta Thunberg: All humanity is now extinct on Earth, because we didn’t do anything about global warming

12:40 pm

Greta Thunberg speaks!
Greta Thunberg speaks!

How dare you! On June 21, 2018, Greta Thunberg informed us — as shown in her tweet to the right — that we only had five years left to stop using fossil fuels, and if we didn’t “climate change will wipe out all of humanity.”

I am hardly the only person to note this example of global warming fraudulence. Numerous reporters have also gleefully noted it, with this essay today at American Thinker by Andrea Widburg probably the most damning, not so much for noting the ignorant rantings of this uneducated high school drop-out whom the left made their icon of knowledge and top global warming expert, but for the list she provides of the endless number of other failed doomsday predictions by global warming activists and politicians.

That list was compiled in 2019, and thus it did not yet include Thunberg’s absurd prediction. Nor did it include the endless string of additional false doomsday predictions that this crowd has continued to issue in the years since, all of which I guarantee without any uncertainty will all fail, just as their hundreds of past doomsday predictions have failed.

You see, the point of those predictions was not to educate, but to instill fear, so as to then justify a power grab by the government. As Widburg concludes:

A lava flow on a Martian lava plain

A lava flow on a Martian lava plain
Click for original image.

While much of surface of the Martian equatorial regions is comprised of volcanic flood lava, the place where it is most obvious and evident is on the flanks of the three giant volcanoes of the Tharsis Bulge. Here, lava did not simple spout from surface vents to flood low-lying large areas, filling those depressions quickly almost like water. Instead it issued from vents on the slopes of those mountains, or from their calderas at their peaks, and flowed downhill almost like tsunamis of magma.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, is a great example. Taken on March 11, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows the foot of one such flow, frozen in place as it oozed down hill from the Arsia Mons, about 300 miles away to the northwest.

Two new European rocket startups sign deal with France to launch from French Guiana

11:28 am

The French space agency CNES today signed agreements with two different European smallsat rocket startups, Spain’s PLD Space and Germany’s Rocket Factory Augsburg (RFA), allowing each to launch from France’s old launchpad in French Guiana that was used in the 1970s by its long abandoned Diamant rocket.

From the RFA press release:

Until now, the launch pad in Kourou has only been used by CNES for its Diamant rocket in the 1970s. Now the launch complex is to be given a new purpose, in the tradition of opening access to space through innovative and groundbreaking ventures. As such, RFA is one of the first NewSpace companies to be given the opportunity to use it. The new launch pad will be upgraded and equipped in the coming years with the aim of being used for launches from 2025.

These agreements are part of a slew that have come out of Europe in the past year or so that all indicate that the European Space Agency (ESA) and its partners have finally abandoned any attempts to build rockets, and are instead looking to private enterprise to do it for them. First Germany encouraged private rocket startups, independent of Arianespace and ESA. Then Spain followed with PLD Space. Then Arianespace, the commercial arm of ESA that for decades built all rockets for ESA, announced it was making agreements with these startups to have them launch payloads instead.

These new deals today indicate that France has now joined the rush to private enterprise, which is a very significant development as France as always been the leader in having ESA build its own rockets through Arianespace. It appears it is now looking away from government-run space.

All these actions are also suggest a dim future for ArianeGoup’s Ariane-6 rocket, built under the old system but with an attempt to give private enterprise more power, with ArianeGroup, not Arianespace, owning and controlling it. Its design however was dictated largely by ESA, thus resulting in a rocket that is too expensive and therefore not competitive.

The long term result will be greater competition, both in Europe and worldwide, which in turn is going to fuel a renaissance in rocket development, which in turn is going to speed the exploration and colonization of the rest of the solar system.

Rocket Lab’s payload on its first suborbital test launch of its Electron rocket

10:00 am

Until today it was unclear whether the successful first suborbital launch of Rocket Lab’s Electron rocket on June 17, 2023 carried a payload. Now we know it did:

The launch took place at NASA’s Wallops Flight Facility in Virginia and demonstrated the Multi-Service Advanced Capability Hypersonic Test Bed, or MACH-TB, program’s first suborbital flight of a hypersonic payload.

MACH-TB is led by the Pentagon’s Test Resource Management Center and the Naval Surface Warfare Center’s Crane Division. The team selected Leidos as the program’s prime integrator last September, and California-based space company Rocket Lab is one of 12 subcontractors supporting the effort.

It appears the Pentagon program that funded MACH-TB is a different program — from a different Pentagon office — from the one that is funding the next suborbital hypersonic test using Electron. Nor is this unusual for the military. The duplication of these Pentagon programs, with multiple bureaucracies, says a lot more about the utter waste and incompetence and corruption in DC than it does about hypersonic suborbital testing.

For Rocket Lab however this duplication is great news, as it provides the company at least two different customers for its suborbital rocket.

FAA finally reduces airspace restrictions for some launches out of Cape Canaveral

9:46 am

On June 15, 2023 FAA announced that it has at last reduced the airspace restrictions for some launches out of Cape Canaveral, thus allowing more launches while reducing the disruption to commercial airline traffic.

The move is part of broader efforts to address the conflicts between launches and commercial aviation, particularly in Florida’s congested airspace. In April, the FAA released a set of factors when considering whether to allow a launch to proceed or ask the launch company to identify alternative windows for the launch.

Among those factors are the timing of the launch, particularly relative to holidays or other special events that cause increases in air traffic, and the duration of the launch window. “The FAA encourages commercial space operations to take place during nighttime hours (to the extent practicable) when other flight operations tend to be reduced,” the guidelines state.

I say “at last” because SpaceX have been pushing for this reduction for years. It knows its rockets will fly very reliably, and even if a rare failure forces their destruction, the territory threatened is much smaller than what was once considered necessary in the past. It just took years to get the federal bureaucracy to recognize these facts.

Northrop Grumman’s robotic servicing satellites gets third contract, this time from Intelsat

9:40 am

With an announced contract with Intelsat today, Northrop Grumman has now obtained contracts for all three of its robotic servicing pods that will be launched on its Mission Servicing Vehicle in 2025.

Intelsat ordered the third and last pod available on the debut mission of the company’s new servicing spacecraft, called Mission Robotic Vehicle (MRV).

Australian communications satellite operator Optus was the first customer to sign up for the Mission Extension Pods, which are propulsion jet packs that add six years to the life of geostationary satellites. Intelsat in April said it purchased one of the pods, followed by today’s announcement that it ordered a second one.

The MRV is an upgrade from Northrop Grumman’s earlier robot, the Mission Extension Vehicle (MEV), which proved that it could autonomously rendezvous and dock with the nozzle of a defunct satellite and provide it with a new thruster and fuel so as to extend its life. With the MRV, multiple revised versions of the MEV are essentially launched at the same time.

Russia gets a launch contract!

9:31 am

In what has become a very rare event, Russia’s state-run press today announced that Roscosmos has won a launch contract for its Soyuz-2 rocket from the United Arab Emirates (UAE).

“On June 27th at 3:34 p.m. UAE time [2:34 Moscow time], [UAE’s] MBR Space Centre will launch its maiden mission, PHI-Demo, from Russia’s Vostochny Cosmodrome using the Soyuz-2 rocket as part of the Payload Hosting Initiative,” the media office said in a statement.

The statement says that the initiative, jointly led by MBRSC [UAE’s space agency] and the United Nations Office for Outer Space Affairs (UNOOSA), is aimed at providing space access and hastening the sustainable progression of novel space technologies.

The satellite will be a secondary payload on the launch of a Russian weather satellite.

It seems this UN office wants to help the Russians, and is working to encourage other nations to use its rockets to get into space. Because of Russia’s invasion of the Ukraine, it has lost all of its international launch business. UNOOSA is apparently working to recover Russia some of that business.

The UAE meanwhile appears to be trying to light the candle from both ends, working extensively with NASA and American private companies while also attempting to partner with Russia and China.

BepiColumbo completes third Mercury flyby

9:23 am

Mercury as seen by BepiColumbo
Click for original image.

On June 19, 2023, the European Mercury orbiter BepiColumbo made the third of six planned flybys of Mercury on its way to orbit around that planet in 2025.

The closest approach was only 146 miles above the planet’s surface. Though no pictures were taken at that point because it was Mercury’s night side, as the spacecraft moved away it used one of its monitoring cameras, designed primarily to monitor the spacecraft itself, to look back at the planet. The picture to the right, cropped, reduced, and sharpened to post here, is one of the first taken. From its caption:

The image was taken at 19:49 UTC (21:49 CEST) by the Mercury Transfer Module’s monitoring camera 3, when the spacecraft was about 2536 km from the planet’s surface. Closest approach took place at 19:34 UT (21:34 CEST) on the night side of the planet at about 236 km altitude. The back of the Mercury Planetary Orbiter’s high-gain antenna and part of the spacecraft’s body is also visible in front of Mercury in this image.

Despite the dark nature of the image, several interesting geological features are seen in beautiful detail. Of particular interest is Beagle Rupes, a 600 km-long scarp that snakes over the surface. In this view it is seen cutting through a distinctive elongated crater named Sveinsdóttir, which likely got its shape from an impactor striking the surface at an angle.

The next flyby will occur on September 5, 2024.

  • An analysis of the landing failure of Hakuto-R1

    • This is thirty minute presentation, which concludes that though there was a failure of the software, in the end the failure was due to management errors, including changing the landing site without doing sufficient simulations.

 

 

  • Delta-4 Heavy launch scheduled for tonight, at 3:29 am Eastern

    • This will be the first Delta-4 Heavy launch in almost three years. More significant, it will be ULA’s first launch in 2023, a number that is even lower that its low launch numbers of recent years. At this pace it will be a challenge for ULA to match its lowest launch counts of five, from ’19 and ’21. UPDATE: Scrubbed, reschedule 24 hours later.
