Blue Origin completes first round of launchpad/New Glenn tanking tests

9:52 am

Link here. In the past week or so Blue Origin has done three tanking tests of its assembled engineering test rocket, simulating fueling of a New Glenn rocket on the launchpad, and now intends to roll that test vehicle back to its rocket assembly building.

From here, it is most likely that the rocket will be prepared for the next round of testing, which will include a static fire of the seven first-stage BE-4 engines. This test will mark the first time that Blue Origin’s BE-4 engines will ignite while integrated with a New Glenn first stage. It will also be the first time that the new launch pad supports an engine firing.

The company continues to aim for a first test launch of New Glenn before the end of the year, and these tests strengthen the likelihood that this schedule is realistic.

UK government to invest £10 million in Saxavord spaceport

9:45 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

The government of the United Kingdom announced yesterday that it will directly invest £10 million in the Saxavord spaceport being built on one of the Shetland Islands, as shown on the map to the right.

Coming in addition to around £40 million of private investment, the government funding will allow SaxaVord to accelerate its capital works programme to ensure it is ready to support the first orbital launch.

That capital works program was forced to shut down last year when red tape at the Civil Aviation Authority (CAA) delayed the licensing of Saxavord. It could be this grant has been issued partly to repay the losses the spaceport company experienced due to those bureaucratic delays. The timing kind of reinforces this speculation, as only yesterday Saxavord got its spaceport license approved, though other approvals remain pending.

All this news suggests strongly that the first test flight at Saxavord by the German rocket startup Rocket Factory Augsburg will occur later this year, as promised.

Meanwhile, the other spaceport in Sutherland must be wondering if it can get similar government aid, or if the government is now playing favorites.

SpaceX: We want to fly next Starship/Superheavy test launch on March 14, 2024

9:07 am

In a tweet yesterday SpaceX announced an update on its Starship webpage, outlining its plans for the third orbital test launch of its heavy-lift Starship/Superheavy rocket, with March 14, 2024 listed as the hoped-for launch date.

The update began with these cautionary words, “pending regulatory approval,” and then went on to describe details of the test flight:

The third flight test aims to build on what we’ve learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship’s payload door, a propellant transfer demonstration during the upper stage’s coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship. It will also fly a new trajectory, with Starship targeted to splashdown in the Indian Ocean. This new flight path enables us to attempt new techniques like in-space engine burns while maximizing public safety.

I suspect the change in the splashdown location, from northeast of the main island of Hawaii, was instigated by the FAA for those “public safety reasons”. From SpaceX’s perspective, this is an easy give, as a slightly shorter flight makes little difference for this test, and it allows the company to test that Raptor engine by firing that de-orbit burn.

Will the flight occur on March 14th? The odds are high, partly because this SpaceX announcement is designed to put pressure on the bureaucrats at the FAA to finish their paperwork already. At the same time, bureaucrats sometimes love to stick it to private citizens, just for fun. We shall see.

Is this really a spiral galaxy?

Is this really a spiral galaxy?

The uncertainty of science: The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and released on March 4, 2024 by the PR department of the European Space Agency (ESA) as part of its Hubble Picture of the Week program. It shows what the press release claims is a spiral galaxy about 55 million light years away, seen edge on.

In this image NGC 4423 appears to have quite an irregular, tubular form, so it might be surprising to find out that it is in fact a spiral galaxy. Knowing this, we can make out the denser central bulge of the galaxy, and the less crowded surrounding disc (the part that comprises the spiral arms).

If NGC 4423 were viewed face-on it would resemble the shape that we most associate with spiral galaxies: the spectacular curving arms sweeping out from a bright centre, interspersed with dimmer, darker, less populated regions. But when observing the skies we are constrained by the relative alignments between Earth and the objects that we are observing: we cannot simply reposition Earth so that we can get a better face-on view of NGC 4423!

This picture provides a great example of the amount of assumptions that are often contained in astronomical observations. Though the data strongly suggests this is spiral, we must remember this is merely an educated guess, based on that central bulge and the dust lanes visible along the galaxy’s profile. There is actually no guarantee that this is so. As the press release also notes, astronomers are constrained by our viewpoint, and cannot change that viewpoint to get a better view to confirm this guess. For all we know, a face on veiw of this flat galaxy would reveal it has no spiral arms, but instead is mottled and chaotic, a rare type that does exist.

Astronomers do the best they can, but it is important that they (and we) always recognize the limitations.

More orbital tugs reach orbit

9:44 am

When SpaceX launches a large number of smallsats and payloads on a Falcon 9 launch, as it did on March 5 from Vandenberg in California, it routinely takes several days or even months for the results from each payload or smallsat to trickle in. Two reports today illustrate the growing cottage industry of orbital tugs.

First, a company named Apex has successfuly demonstrated its first service module for satellites, designed to provide the basic services needed for satellites so that companies can focus on designing their primary mission rather than reinventing a basic satellite each time. The module was launched on March 5th, and has been operating as expected. The company hopes to begin mass producing this service module in a new factory later this year.

Second, a new orbital tug company from France, Exotrail, has successfully deployed a cubesat from its first tug. That tug was launched on a Falcon 9 smallsat launch in November, and has been testing operations since. After releasing that cubesat for Airbus’s defense division, the tug is continuing operations, acting as the service module for a second payload from Belgium that is testing its own gyros and reaction wheels for controling smallsat orientation.

These companies are small, and are focused on very specific technologies needed by smallsats to operate efficiently in space. As such, their achievements are generally more mundane and less exciting that a SpaceX Starship/Superheavy test launch, by many magnitudes. Nonetheless, their success, not only technically but financially, suggests a growing maturity to the in-orbit space industry, which will also lay the groundwork for much more sophisticated operations in the future beyond Earth orbit. The people that build these tugs will move on to build vessels that can go to the planets and do things that are presently impossible or too difficult, and do it at low cost and very quickly.

Another helicopter mission under development for Mars?

Another helicopter mission for Mars?
Click for original image.

Today’s cool image to the right, cropped to post here, is probably on its own one of the more boring cool images I have posted over the years, a generally featureless plain with some ripple dunes within a few low hollows.

What makes this picture cool however is the label for the image: “Sample Landing and Traverse Hazards at Possible Helicopter Landing Site.” The picture was taken on January 23, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), with the obvious goal of seeing whether this location can serve as a landing site for a helicopter mission to Mars.

The site is relatively uninteresting because the first goal is to find a safe place to land, but to do so near a location where there is rough geology which only a helicopter can explore. And it appears, from the overview map below, that is exactly what this location is.

Blue Origin is targeting a first unmanned landing of its manned lunar lander in 2025

10:36 am

Blue Origin's Blue Moon manned lunar lander
An early visualization of Blue Moon

According to one Blue Origin official, the company is now targeting its first unmanned landing of its manned lunar lander, Blue Moon, for sometime in 2025, far sooner than previously expected.

Jeff Bezos’ Blue Origin space venture is aiming to send an uncrewed lander to the surface of the moon in the next 12 to 16 months, according to the executive in charge of the development program. John Couluris, senior vice president for lunar permanence at Blue Origin, provided an update on the company’s moon lander program on CBS’ “60 Minutes” news program on Sunday. “We’re expecting to land on the moon between 12 and 16 months from today,” Couluris said. “I understand I’m saying that publicly, but that’s what our team is aiming towards.”

Blue Moon is shown in the graphic to the right. Though being built to provide NASA a second manned lander in addtion to SpaceX’s Starship, this first mission will simply bring cargo to the surface, as a test of the lander itself.

If Blue Origin can keep even somewhat close to this schedule, we will likely have two manned moon landers doing test flights at almost the same time.

A sidebar: Note the lander’s height, as well as the narrow footprint of its landing legs. New graphics of this lander from Blue Origin show the same high center of gravity with an even narrower footprint for the legs. One wonders why. Wouldn’t it make sense to have those legs deploy outward more?

This issue applies also to SpaceX’s Starship, which will also have a high center of gravity. When SpaceX’s rockets land on Earth (both Falcon 9 boosters and Starship), most of their fuel is gone so the bulk of the mass is near the bottom where the engines are, even though the boosters stand very high. On the Moon however these vehicles will be landing heavily loaded, with cargo and fuel. This raises a stability question that was illustrated sadly by the tipping over recently of Intuitive Machines Odysseus lander.

I am not an engineer, so I admit that my off the cuff analysis here is very questionable. Nonetheless, one wonders.

Scientists: Europa produces oxygen on its surface, but less than expected

10:18 am

Graphic of Europa
Click for original image.

The uncertainty of science: Scientists using data from a 2022 flyby of the Jupiter moon Europa by the orbiter Juno have determined that the moon produces about 1,000 tons of oxygen every 24 hours on its surface, a large amount but less than most predictions based on previous indirect observations.

The paper’s authors estimate the amount of oxygen produced to be around 26 pounds every second (12 kilograms per second). Previous estimates range from a few pounds to over 2,000 pounds per second (over 1,000 kilograms per second). Scientists believe that some of the oxygen produced in this manner could work its way into the moon’s subsurface ocean as a possible source of metabolic energy.

You can read the paper here. The graphic shows the basic process, as presently theorized. What remains unknown is how or even if that oxygen is transported downward to the theorized underground ocean of liquid water. That the amount created is on the very low end of previous estimates suggests that there will be less free oxygen to support life in that ocean than expected.

SpaceX almost completes dress rehearsal countdown of Starship/Superheavy

10:02 am

According to a tweet from SpaceX, the company yesterday conduceted a dress rehearsal countdown of Starship/Superheavy, ending the rehearsal at T-10 seconds so that no static fire test of Superheavy’s engines occurred.

Starship completed its rehearsal for launch, loading more than 10 million pounds of propellant on Starship and Super Heavy and taking the flight-like countdown to T-10 seconds.

Prior to all its launches SpaceX routinely does this kind of rehearsal, but always ends them at T-0 and a short engine burst. That it did not do so here suggests either some issue prevented it, or the company was doing tests of its propellant loading procedures. Either way, it is likely another dress rehearsal countdown will be required before the actual test flight can occur.

I also suspect the FAA is involved in this in some way, demanding certain actions by SpaceX before the agency issues the launch license. At the moment there is no word when that license will be issued, though Elon Musk keeps saying on X that it is coming “soon.”

Australian rocket startup gets government approval for its spaceport

9:55 am

Proposed Australian commercial spaceports

The Australian rocket startup Gilmour Space has now received a spaceport licence from the Australian government, allowing launches to occur from its Bowen spaceport on the northeast coast of Australia, as shown on the map to the right.

The company describes the approval from [Ed Husic Federal Minister for Industry and Science], who is also the minister in charge of the Australian Space Agency, as a vote of confidence in Gilmour’s technical capability, paving the way for the launch of Australia’s first sovereign-made rockets, ‘bridging Country to Sky’. Gilmour Space has also secured approval from the Department of Climate Change, Energy, the Environment and Water, enabling the operation of the spaceport at Abbot Point.

Not all is unicorns and rainbows however. First, it appears Gilmour began negotiating for this approval two years ago, so the government took a looong time to say yes. The other spaceport on the map has been awaiting for a launch license for about the same length of time, and has still not gotten it.

Gilmour also wants to do its first test launch of its Eris rocket in the next few months, but it is still awaiting its launch license from the Australian Space Agency. We are therefore about to find out whether Australia’s government can issue that permit in the next few months, or will instead emulate Great Britain, and bog things down with endless red tape.

JPL requests proposals from the private sector for Mars exploration

9:44 am

Capitalism in space: JPL, which is the lead agency running NASA’s very troubled Mars Sample Return (MSR) mission, has now issued a request for proposals from the private sector for doing a variety of Mars missions.

NASA’s Jet Propulsion Laboratory issued a request for proposals Jan. 29 for “commercial service studies” for future robotic Mars mission concepts. The studies, with a value of $200,000 or $300,000, would be carried out over 12 weeks. The studies are intended to examine four specific design reference missions to explore commercial opportunities to support Mars exploration: delivery of small payloads of up to 20 kilograms to Mars orbit, delivery of large payloads of up to 1,250 kilograms to Mars orbit, services to provide high-resolution imaging of the Martian surface and communications relay services between Mars and Earth.

Missions to provide imaging or communications from Mars orbit could quite easily be provided by numerous private companies. Delivering payloads to the Martian service is exactly what SpaceX proposes with Starship, and is also what several lunar lander companies have now been doing.

Up until now, JPL has always built everything in-house, or if it didn’t it designed and managed everything very closely. The result with MSR is a project that is now poorly managed, vastly over budget and behind schedule, and very likely to fail. This proposal suggests JPL is now recognizing that private enterprise might be able to do it better, as NASA has now proven with its shift from being the builder to becoming merely a customer.

If so, this proposal might be indicating the first step at JPL and NASA in imposing a major change in MSR itself, coming as it does just days after the release of an inspector general report about that project’s many problems.

Texas approves SpaceX land swap

9:31 am

Despite a concerted effort by a small group of activists to stop it, the Texas Parks and Wildlife Commission yesterday approved a proposed land swap that would give SpaceX 43 acres of state park land in exchange for receiving 477 acres in a nearby wildlife refuge.

The commission said that the land swap “would create a tenfold return,” allowing the Texas Parks and Wildlife Department to begin planning for a new state park that would give the public access to fishing, kayaking, hiking and other outdoor activities.

…The 43 acres it would give to SpaceX are “noncontiguous,” with the commission noting that most of the acres “do not connect to each other or to areas offering public access at Boca Chica State Park.”

“These smaller, noncontiguous tracts do not provide beach access and are dotted among private properties or immediately adjacent to SpaceX’s facilities, meaning they aren’t readily available for public use and provide less cohesive wildlife habitat than offered by a connected and consistently managed tract of conservation land,” the announcement reads.

The opposition came from the same activist groups that have been attempting by lawfare in every way to shut SpaceX down. They claim in the article at the link that “SpaceX has a history of being a bad neighbor, wreaking havoc on the communities and habitat nearby,” but there is zero evidence of this. Even Fish & Wildlife was forced in its own environmental report to admit that there was no reason to block Starship/Superheavy launches at Boca Chica. And the general community is enthused about the presence of SpaceX because of the billions of dollars of new investment and tens of thousands of new jobs it has brought to the Brownsville region.

These activist groups are simply another visible expression of the irrational hatred the left now holds for Elon Musk, because he has dared defy the left in a number of ways. Sadly, these groups routinely get strong help from every media source (also part of that left), always getting quoted and always getting treated as if they are a major political force in the region, when only a tiny minority in south Texas is on their side.
