The panorama above, cropped, enhanced, and annotated to post here, was taken by left navigation camera on the Mars rover Perseverance on February 27, 2023, looking ahead at its future path on the delta that flowed into Jezero Crater sometime into the past. The arrow points at Ingenuity, now sitting ahead of the rover after completing its 46th flight sometime this weekend.

On the overview map to the right, Perservance’s present location is indicated by the blue dot. The green dot marks Ingenuity’s position, and the yellow lines indicate the approximate area viewed by the panorama above. The red dotted line indicates Perseverance planned future route, though it is likely the science team will make many side trips along the way. The bigger dots are points of special interest, where the scientists hope to drill for core samples.

The ridge on the right is the rim of Belva Crater. The higher mountain behind it is likely the rim of Jezero Crater itself, about four miles away. The helicopter sits about 250 feet away.

Unlike the rocky terrain where Curiosity is presently traveling in the foothills of Mount Sharp in Gale Crater, the terrain here in Jezero Crater appears much more benign, almost like a sand desert of dunes. This is not sand, nor are the hills dunes, but wind erosion and dust appear to have smoothed and hidden the geology more than in Gale Crater.

ESA invites private companies to build lunar satellites for communications and navigation

9:47 am

Capitalism in space: The European Space Agency (ESA) has now invited European and Canadian companies to build the lunar communications and navigation satellites that will be needed to serve the many future manned and unmanned missions presently being planned by the U.S. and Europe.

Under its Moonlight programme, ESA is inviting space companies to create these lunar services.

By acting as an anchor customer, ESA is enabling space companies involved in Moonlight to create a telecommunication and navigation service for the agency, while being free to sell lunar services and solutions to other agencies and commercial ventures.

Once Moonlight is in place, companies could create new applications in areas such as education, media and entertainment – as well as inspiring young people to study science, technology, engineering and maths, which creates a highly qualified future workforce.

According to the press release, almost 100 companies have already expressed interest.

It is however unclear how much freedom the companies will have in designing and creating these satellites, based on ESA’s own descriptions of the project. It appears that ESA wants to design them, and is simply looking for private companies to build them. Under this arrangement, ownership will not belong to the companies, even if they are given the freedom to make money selling the capability to others. In fact, past history suggests that in the end, ESA will eventually retract this part of the deal, because of its desire to fully control the satellites it designed.

NASA names solar scientist as its new science head

9:32 am

NASA today announced the appointment of solar scientist Nicola Fox as the chief of the agency’s science division, taking over from solar scientist Thomas Zurbuchen.

Fox’s actual qualifications for the job are stellar.

Born in Hitchin, Herefordshire, England, Fox received a B.S. in physics from The Imperial College of Science, Technology and Medicine in London, an M.S. in Telematics and Satellite Communications from the University of Surrey, and returned to Imperial College London for her Ph.D. in Space and Atmospheric Physics. She worked at NASA’s Goddard Space Flight Center before joining APL in 1998.

At NASA Fox has led its the solar science division, as well as been the project scientist for the Parker Solar Probe, presently orbiting the Sun.

For the Biden administration and our modern culture that unfortunately always seems more focused on race and gender, the only thing that really matters about Fox however is her sex, a fact that the linked article seems obligated to mention in this manner:

Only one other woman, Mary Cleave, an environmental research engineer and former astronaut, has headed [the science division] in the agency’s almost 65-year history.

How evil! Our racist society oppressed women all those years, holding them back!

In fact, it is actually becoming increasing difficult for any white and heterosexual male to get major management jobs anywhere. The race- and gender-baiters always talk about getting rid of the “glass ceiling,” but in their obsession with giving jobs to woman and minorities, they have simply placed it over others.

Ispace provides update on its Hakuto-R1 lunar lander on the way to the Moon

9:09 am

Lunar map showing Hakuto-R1's landing spot
Hakuto-R1’s planned landing site is in Atlas Crater.

The CEO of the Japanese company Ispace yesterday gave a media briefing on the status of its Hakuto-R1 lunar lander, essentially stating that the spacecraft is doing fine and is on target to land on the Moon at the end of April as planned.

Ispace CEO Takeshi Hakamada said during a media briefing Monday that the flight has provided operational data that will inform subsequent missions. “We have acquired tons of data and know-how” on the lander and its subsystems, he said. “They are very viable assets for ispace.”

That includes information on the lander’s structural performance during launch and deployment, as well as the performance of thermal, communication and power subsystems. “It’s almost impossible to assume everything perfectly before the mission,” Hakamada said. “It is inevitable to face off-nominal events.” Some off-nominal events in the mission so far include thermal temperatures hotter than the company anticipated and a brief, unexpected issues with communications after the lander deployed from the Falcon 9. The thermal issues have not affected operations.

This mission, while carrying commercial payloads such as the UAE’s Rashid lunar rover, is mainly aimed at finding out these engineering details in order to make the next two missions in ’24 and ’25 more likely to succeed. The ’24 mission is also planned as a test mission, but it will carry commercial payloads for both Japanese and Taiwanese customers. On the ’25 mission, the main customer is NASA.

SpaceX’s Falcon 9 launches 21 second generation Starlink satellites

4:33 pm

SpaceX today successfully launched 21 second generation Starlink satellites, dubbed V2-minis because they are smaller than the full version that will be launched on Starship.

The Falcon 9 rocket used a first stage flying on its third flight. It successfully landed on a drone ship in the Atlantic. The fairings were completing their second flight.

The 2023 launch race:

13 SpaceX
7 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise now leads China 14 to 7 in the national rankings, and the entire world combined 14 to 12. SpaceX alone leads the entire world combined 13 to 12.

Drilling success for Curiosity in the marker layer?

The fifth drill hole in the marker band
Click for original image.

It appears from the most recent image sent back from Curiosity today of its February 25, 2023 attempt to drill into the marker layer on Mount Sharp — the fifth such attempt — the rover finally succeeded in getting deep enough to collect sufficient sample material for analysis.

That image is to the right, cropped, reduced, and sharpened to post here. Note that it is not yet confirmed from the science team that this drill attempt was deep enough. What makes this particular drilling attempt intriguing is how the many thin layers of the marker layer responded to the stress of the drill. The top layer cracked like a plate and separated from the adjacent lower layer during drilling. It apparently was hard enough to retain most of its structure, and rather than crumble the drill stresses caused a large section to break away and lift off.

The panorama above, cropped and reduced to post here, was taken the same day from this location, produced from 37 photos taken by the rover’s right navigation camera. The cropped section above looks forward at what I previously labeled “a Martian hill of pillows.” The overview map below shows the context of this panorama.

Galaxies afloat in space

Galaxies afloat in space
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today. It is part of a survey project studying what the press release calls “jellyfish galaxies,” spiral galaxies that have long extended arms.

As jellyfish galaxies move through intergalactic space they are slowly stripped of gas, which trails behind the galaxy in tendrils illuminated by clumps of star formation. These blue tendrils are visible drifting below the core of this galaxy, and give it its jellyfish-like appearance. This particular jellyfish galaxy — known as JO201 — lies in the constellation Cetus, which is named after a sea monster from ancient Greek mythology. This sea-monster-themed constellation adds to the nautical theme of this image.

On the lower left is what the press release calls an elliptical galaxy, probably because it has no obvious arms. It is however shaped more like a spiral galaxy, since ellipticals tend to be spherical. If you look close you will also notice at least five-plus other galaxies in this picture, all smaller either because they are much farther away or are simply much smaller.

New company aims at providing floating ocean-going spaceports for rocket companies

9:29 am

A new startup, The Spaceport Company, is building a floating ocean-going spaceport for smallsat rocket companies, with the company’s long term goal to provide a range of floating spaceports for rockets of all sizes.

The Spaceport Company is planning to demonstrate a sea-based launch platform in May, conducting four sounding rocket launches from a modified ship in the Gulf of Mexico. “That will help us prove out our logistical, operational and regulatory procedures,” said Tom Marotta, founder and chief executive of the company, during a panel at the SpaceCom conference Feb. 23.

Those tests will be a precursor to developing a full-scale sea-based platform, based on a ship design called a liftboat. That ship can sail to a location and lower legs to anchor itself on the seafloor. The boat can then lift itself out of the water and serve [as] a launch platform.

That first orbital platform would provide launch services for smallsat rockets capable of launching up to one ton, and if the company’s suborbital test launches go well and further investment capital arrives, could be operational by 2025.

Astroscale raises $76 million in private investment capital from Mitsubishi, space tourist Maezawa, and others

9:20 am

The Japanese startup Astroscale, which is focused on removing orbital space junk and robotic satellite repair, has raised $76 million in private investment capital, bringing the total it has raised from private sources to $376 million.

Astroscale Holdings Inc. (“Astroscale”), the market leader in satellite servicing and long-term sustainability across all orbits, has closed a Series G round with more than U.S. $76 million in funding from new investors Mitsubishi Electric, Yusaku Maezawa, Mitsubishi UFJ Bank, Mitsubishi Corporation, Development Bank of Japan, and FEL Corporation.

The investors are of interest. Billionaire Maezawa, who has already flown to ISS as a tourist and has purchased a lunar mission on SpaceX’s Starship, contributed $23 million of the $76 million. Mitsubishi in turn has contributed at least $25 million. Both suggest Astroscale is now on very solid financial ground.

It also appears that the big players in Japan see Astroscale’s business plan as viable and expected to be profitable.

Manned Endeavour launch tonight on Falcon 9 scrubbed at T-2:12

12:05 am

UPDATE: New launch date, still tentative pending investigation into the technical issue that forced tonight’s scrub, is now March 2, 2023, at 12:32 am Eastern.

The fourth manned launch of SpaceX’s Endeavour Dragon capsule, carrying four astronauts, was scrubbed tonight at T-2:12 because of an issue with ground ignition system of the rocket. As of posting no additional details had been released, as the launch team was in the process of standing down, unloading the fuel from the rocket in preparation for getting the astronauts out of the capsule safely.

Assuming the issue can be fixed quickly, there is another launch opportunity tomorrow, February 28, at 1:22 am (Eastern). For SpaceX a launch scrub for technical reasons has become remarkably rare. In fact, the only other scrub since 2020 for technical reasons took place in July 2022. During that time the company successfully launched more than 100 times, thus getting off the ground as scheduled about 99% of the time, excluding weather delays.

While the Endeavour capsule will be making its fourth flight, when this launch finally takes place the rocket’s first stage is a new stage and will be making its first flight. This has also become a relatively rare event for SpaceX. In 2022, of the company’s 61 launches, only three used new first stages. So far this year this launch will be the second new stage to fly, out of the thirteen launches so far.

IBEX in safe mode

11:38 am

On February 18, 2023, NASA’s Interstellar Boundary Explorer (IBEX) went into what the engineers have dubbed “contingency mode”, which seems to be a variation of safe mode, due to a computer issue that is preventing the spacecraft from accepting commands.

While fight [sic] computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command capability by resetting ground systems hardware and software.

Flight software still is running, and the spacecraft systems appear to be functional. However, while uplink signals are reaching the spacecraft, commands are not processing. If the mission team’s efforts to find and remedy the loss of command capability remain unsuccessful, IBEX will perform an autonomous reset and power cycle on March 4.

IBEX was designed to study the boundary between the interstellar space and the solar system, and do it somehow from Earth orbit.

Meandering ridges in Greg Crater

Meandering ridges in Greg Crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on November 29, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “curved ridges.”

These might be inverted channels, the beds on which either water or ice flowed, compacting it down so that it became very resistant to erosion, and thus remains when the surrounding terrain was worn away. However, none of them seem to follow any grade. A more likely explanation is that these are ancient moraines, the debris pile pushed ahead of a glacier and then left behind when the glacier goes away.

The location is the reason I favor this explanation.

Puerto Rico’s Ports Authority is looking for an operator to run the island’s own spaceport

10:09 am

Ceiba spaceport map
The arrow points to the city of Ceiba

Puerto Rico’s Ports Authority has now issued a call for proposals from potential operators of the spaceport the authority wishes built at an airport in the town of Ceiba on the island’s eastern tip.

The developer — which would operate the Spaceport for several years, depending on the negotiation — would design and build the infrastructure needed for horizontal launches at JAT, using private capital, equity and investment.

…“Vertical launches in Puerto Rico are challenging, considering the population density, among others. However, we want to do a feasibility study for vertical launches in Puerto Rico, with an emphasis on the use of barges and launches in high seas,” the agency stated in the RFP.

Note that the first goal would be to make the airport usable for rocket companies that use an airplane for their first stage, such as Virgin Orbit and Northrop Grumman. The next step would be figure out where a vertical launchpad could be safely and practically established.

Many carbon-based molecules identified in Ryugu samples

9:53 am

Researchers in Japan, Europe, and the U.S. have now identified many carbon-based molecules in the Ryugu samples brought back to Earth by Japan’s Hayabusa-2 asteroid probe. From their paper, published in Science yesterday:

We identified numerous organic molecules in the Ryugu samples. Mass spectroscopy detected hundreds of thousands of ion signals, which we assigned to ~20,000 elementary compositions consisting of carbon, hydrogen, nitrogen, oxygen, and/or sulfur. Fifteen amino acids, including glycine, alanine, and α-aminobutyric acid, were identified. These were present as racemic mixtures (equal right- and left-handed abundances), consistent with an abiotic origin. Aliphatic amines (such as methylamine) and carboxylic acids (such as acetic acid) were also detected, likely retained on Ryugu as organic salts.

The presence of aromatic hydrocarbons, including alkylbenzenes, fluoranthene, and pyrene, implies hydrothermal processing on Ryugu’s parent body and/or presolar synthesis in the interstellar medium. Nitrogen-containing heterocyclic compounds were identified as their alkylated homologs, which could have been synthesized from simple aldehydes and ammonia. In situ analysis of a grain surface showed heterogeneous spatial distribution of alkylated homologs of nitrogen- and/or oxygen-containing compounds.

The large number of carbon-based molecules is not unlike data from similar carbonaceous chondrite meteorites, though the differences appear to suggest Ryugu experienced chemical processes in connection with water during its lifetime.

Note for clarity: Organic molecules are not life. This is a term scientists use for any carbon-based molecule.

Scientists pin down Venus’s most likely active volcanic regions

9:40 am

The Aine corona on Venus

Click for original image.

Using archival data from the Magellan radar imaging Venus orbiter from the early 1990s, scientists think they have identified the regions Venus that are most likely to have active volcanoes, places that have a unique Venusian circular feature called coronae.

The researchers focused on 65 previously unstudied coronae that are up to a few hundred miles across. To calculate the thickness of the lithosphere surrounding them, they measured the depth of the trenches and ridges around each corona. What they found is that ridges are spaced more closely together in areas where the lithosphere is more flexible, or elastic. By applying a computer model of how an elastic lithosphere bends, they determined that, on average, the lithosphere around each corona is about 7 miles (11 kilometers) thick – much thinner than previous studies suggest. These regions have an estimated heat flow that is greater than Earth’s average, suggesting that coronae are geologically active.

Thus, more volcanic activity, releasing the planet’s interior heat outward.

This research confirms other work done looking at coronae back in 2020.

ULA now targets May 4th for first Vulcan launch

9:23 am

According to ULA’s CEO, the company has now scheduled the first launch of its Vulcan rocket for May 4, 2023, a delay of about a month from the previous schedule.

The delay to the new date was caused by a variety of factors. First, the launch window for the prime payload, Astrobotic’s Peregrine lunar lander, is only open certain days of the month. Second, that lander is just finishing final testing, and the extra time was needed to get it to Cape Canaveral and stacked on the rocket. Third, the extra time was needed to complete all the dress rehearsal countdown tests prior to launch. However, the biggest reason for the delay appears to have been one of Blue Origin’s BE-4 rocket engines.

ULA and Blue Origin are finishing the formal qualification of the BE-4 engine, which Bruno described as the “pacing item” for the launch. “It’s taking a little bit longer than anticipated.”

He revealed that, in a qualification test of one of two engines, the liquid oxygen pump had about 5% higher performance than expected or seen on other engines. “When the performance of your hardware has even a small shift that you didn’t expect, sometimes that is telling us that there could be something else going on in the system that is potentially of greater concern.”

ULA and Blue Origin decided to take the engine off the test stand and disassemble it. Engineers concluded that the higher performance was just “unit-to-unit variation” and not a problem with the engine itself, Bruno said.

If Blue Origin was manufacturing and testing these engines as it needs to do, in large numbers, it would have known a long time ago the range of “unit-to-unit variation” in performance. That this is not known at this late time once again tells us that the company is still struggling to build these engines routinely. Yet it will soon need to produce plenty in short order in order to sustain not only ULA’s Vulcan launch schedule but the launch schedule of its own New Glenn rocket.

Ingenuity completes 45th flight; Perservance races to keep up

6:48 pm

Overview map
Click for interactive map.

On February 22, 2023, the Mars helicopter Ingenuity completed its 45th flight on Mars, flying 1,627 feet in 2 minutes and 24 seconds. This was 13 feet farther than planned, and 5 seconds longer, the extra distance likely because the helicopter needed to find a good landing spot.

The green dot on the map to the right indicates Ingenuity’s new position. The blue dot marks Perseverance’s position. The rover has been moving fast, quickly climbing up onto the delta behind Ingenuity only days after it has completed each recent flight. It appears the Perseverance science team wishes to reach the top of the delta as fast as possible, where it can then begin drilling for more core samples.

It is becoming increasing clear the limitations of Perseverance. It was designed to obtain these core samples for return to Earth, but in the process many of the geological tools and sensors that Curiosity carries were eliminated. The result is the Perseverance can’t actually find out as much about the geology in Jezero Crater as Curiosity can. This doesn’t mean it can’t do any geological work, because it certainly can, but all of the analysis of drill samples that Curiosity does is beyond Perservance’s capabilities. It basically can only do contact science and close inspection. The analysis of its drilled samples must wait until the samples are returned to Earth, about a decade from now.

Russians launch unmanned Soyuz to ISS

5:34 pm

The Russians today successfully launched an unmanned Soyuz capsule to ISS to replace the capsule damaged by a coolant leak in December.

The new capsule will dock to ISS in two days, on February 25th. Then on February 27th a Falcon 9 rocket will launch four astronauts on its Endurance reusable Dragon capsule. The damaged Soyuz capsule will be de-orbited shortly thereafter.

Because of the new Soyuz was intended to remain in orbit with its crew until September, Roscosmos and NASA agreed to keep the crew from the damaged Soyuz on ISS until then, making the mission of these two Russians and American Frank Rubio about a year long. There is a chance Rubio could set a new record for the longest American mission, depending on the exact day his mission returns.

  • Russia now targets a July 13, 2023 launch date for its Luna-25 Moon lander

    • Though this mission has been delayed endlessly, and Russia has also been forced to delay its later planned unmanned lunar probes due to its lack of certain components formerly obtained from the west before its invasion of the Ukraine, I now expect this launch to happen on that date or reasonable close to it.

Soft Martian buttes

Soft Martian buttes
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 1, 2023 by the high resolution camera on Mars Reconnaissance Orbiter to fill a gap in its shooting schedule so that the scientists could maintain the camera at its proper temperature.

In other words, the picture was not taken as part of any particular research project. Its target was in a sense chosen almost at random, though the science team always tries to find something of interest in such situations. In this case I think they succeeded, as these soft terraced buttes illustrate well the alien nature of Mars. The ground is barren, with absolutely no evidence of any life, and it appears that the buttes have been softened and eroded by eons of wind action. You can see evidence of this by the handful of dust devil tracks that cross the buttes.

There is more.

What to expect when SpaceX launches Starship on its first orbital flight

10:04 am

Link here. The article does a careful review of the previous dress rehearsal countdowns and static fire tests, especially the last which successfully fired 31 of Superheavy’s 33 Raptor-2 engines for 7 seconds, in order to understand what will happen during the countdown on the day the rocket does its first orbital launch, now expected within weeks.

It appears right now that SpaceX is preparing to replace one or both of those failed engines, and do it with Superheavy prototype #7 still mounted to the launchpad. Starship prototype #24 has not yet been stacked on top, but work is presently being done to it nearby to prepare it for launch. For example, workers recently have removed the attachment points used by cranes before the chopsticks existed and put thermal tiles there instead.

Based on the pace of work, SpaceX should be ready to launch by mid-March. All that will prevent this will be the FAA, which still has not approved the launch license.

Webb spots massive galaxies in the early universe that should not exist at that time

9:45 am

The uncertainty of science: Astronomers using the Webb Space Telescope have identified six galaxies that are far too massive and evolved to have formed so quickly after the Big Bang.

The research, published today in Nature, could upend our model of the Universe and force a drastic rethink of how the first galaxies formed after the Big Bang. “We’ve never observed galaxies of this colossal size, this early on after the Big Bang,” says lead researcher Associate Professor Ivo Labbé from Swinburne University of Technology.

“The six galaxies we found are more than 12 billion years old, only 500 to 700 million years after the Big Bang, reaching sizes up to 100 billion times the mass of our sun. This is too big to even exist within current models.

You can read the paper here [pdf]. The “current models” Labbé is referring to are all the present theories and data that say the Big Bang occurred 13.7 billion years ago. These galaxies, however, found less than a billion years after that event, would have needed 12 billion years to have accumulated their mass.

If confirmed, these galaxies essentially tell us that the Big Bang is wrong, or very very VERY incomplete, and that all the data found that dates its occurrence 13.7 billion years ago, based on the Hubble constant, must be reanalyzed.

It is also possible these galaxies are actually not galaxies, but a new kind of supermassive black hole able to form very quickly. Expect many scientists who are heavily invested in the Big Bang to push for this explanation. It might be true, but their biases are true also, which means that Webb is presenting us with new data that calls for strong skepticism of all conclusions, across the board.

MAVEN experiences problem with attitude control system

9:27 am

The Mars orbiter MAVEN has had to shut down its inertial measurement unit (IMU), used to tell the spacecraft its orientation in space and pointing direction, after it experienced a problem and caused the spacecraft to enter safe mode temporarily.

The IMU had been powered up in preparation for a minor maneuver targeted to reduce eclipse durations in 2027. On Feb.17, MAVEN exited safe mode and is currently operating in all stellar mode, a mode that does not rely on IMU measurements such that the IMU can be powered off to conserve its lifetime. The maneuver will be waived as the team evaluates the path forward. Relay activities and nominal science operations are scheduled to resume on Feb. 23.

“Relay activities” is NASA’s vague way of describing MAVEN’s job as a communications satellite for the rovers on the surface of Mars. Losing this satellite would hamper those operations somewhat, though there are several other orbiters available to pick up the task, with Mars Odyssey presently tasked to able to handle most communications relays.

China’s Long March 3B rocket launches communications satellite

9:19 am

China today successfully used its Long March 3B rocket, launching from an interior spaceport, to place a satellite into orbit to provide “high-speed broadband access services for fixed terminals, vehicle/ship/airborne terminals.”

Little other information has been released, but that description sounds remarkably similar to what OneWeb’s satellite constellation does.

No word on whether the rocket’s lower stages crashed near habitable areas.

Cliffs inside 285-mile-wide Schiaparelli Crater on Mars

Cliffs inside Schiaparelli Crater

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and was labeled by the science team as showing “dramatic cliffs and swirls in mound-skirting unit.”

I estimate the tallest point of this cliff butte to be somewhere between 500 and 800 feet high. And while the cliff is what first attracts the eye, one mustn’t ignore the vast amounts of dust and sand that cover everything here. The small teardrop-shaped buttes on the upper plateau suggest the prevailing wind direction there is from the north to the south. However, the north-south orientation of the ripple dunes on the floor below suggests that the prevailing wind direction below the cliff is east-west. Explaining how the topography could so quickly change the prevailing wind direction is beyond my skill.

The swirls mentioned by the scientists can be seen at the top of the cliff (on the left) and just below its base, in areas where there appears to be less dust. Those swirls reveal the many geological layers here.

SpaceX ready to launch Starship prototype #24 into orbit

10:07 am

According to a statement yesterday by one SpaceX official, the company is now ready to launch its Superheavy #7 booster, stacked with its Starship prototype #24, on an orbital test flight, with the only remaining obstacle to launch the launch license, not yet approved by the FAA.

Speaking on a panel at the Space Mobility conference here about “rocket cargo” delivery, Gary Henry, senior advisor for national security space solutions at SpaceX, said both the Super Heavy booster and its launch pad were in good shape after the Feb. 9 test, clearing the way for an orbital launch that is still pending a Federal Aviation Administration launch license. “We had a successful hot fire, and that was really the last box to check,” he said. “The vehicle is in good shape. The pad is in good shape.”

…“Pretty much all of the prerequisites to supporting an orbital demonstration attempt here in the next month or so look good,” he said.

Henry also outlined SpaceX’s overall plans for Starship in the next year or two, beginning with a series of test/operational launches that will iron out the kinks of the rocket while simultaneously placing Starlink satellites into orbit. At the same time, development will shift to creating a Moon lander version of Starship for NASA’S Artemis program, including doing refueling tests of Starship in orbit. These test flights will also lead quickly to the three private manned flights that SpaceX already has contracts for, including two around the Moon and one in Earth orbit.

NASA signs deal to launch Israel’s first space telescope mission

9:50 am

NASA today announced that it has agreed to provide the launch opportunity for Israel’s first space telescope, dubbed the Ultraviolet Transient Astronomy Satellite (ULTRASAT), designed to make wide-field ultraviolet observations from geosynchronous orbit.

Led by the Israel Space Agency and Weizmann Institute of Science, ULTRASAT is planned for launch into geostationary orbit around Earth in early 2026. In addition to providing the launch service, NASA will also participate in the mission’s science program.

The press release, both from NASA and from Weizmann, was remarkably vague about how NASA will provide that launch capability. The only orbital rocket NASA has is SLS. Will ULTRASAT launch as a secondary payload on a future Artemis launch? Or will NASA buy launch services from another rocket company? The press releases did not say.

Regardless, this deal means that American taxpayers have agreed to foot the launch cost of this Israeli space telescope, in exchange for obtaining telescope time for American astronomers. Interestingly, the press releases also provided no information about how much that launch cost would be.

There has long been a need for a dedicated new ultraviolet space telescope, so this deal could be a good one for American astronomers and a worthwhile use of some of NASA’s budget. It just seems inappropriate for NASA to keep the details so secret.

Japanese startup enters the high altitude balloon space tourism business

9:35 am

A Japanese startup, Iwaya Giken, announced yesterday that it is building a two-person capsule that will carry two persons, a pilot and passenger, on high-altitude stratospheric tourist balloon flights for about $180K per ticket.

The company, Iwaya Giken, based in Sapporo in northern Japan, has been working on the project since 2012 and says it has developed an airtight two-seat cabin and a balloon capable of rising up to an altitude of 25 kilometers (15 miles), where the curve of the Earth can be clearly viewed. While passengers won’t be in outer space — the balloon only goes up to roughly the middle of the stratosphere — they’ll be higher than a jet plane flies and have an unobstructed view of outer space.

The company teamed up with major Japanese travel agency JTB Corp., which announced plans to collaborate on the project when the company is ready for a commercial trip. Initially, a flight would cost about 24 million yen ($180,000), but Iwaya said he aims to eventually bring it down to several million yen (tens of thousands of dollars).

No date for the first launch was mentioned. This company now joins two American balloon companies as well as a Spanish balloon company, all planning to offer rides to the edge of space.
