Japanese satellite startup Synspective raises $100 million

10:08 am

Capitalism in space: The Japanese satellite startup Synspective announced today that it has successfully raised $100 million in private investment capital.

The latest funding was led by Sompo Japan Insurance Inc. (Tokyo, Japan), Nomura SPARX Investment, Inc. (Tokyo, Japan), and Pavilion Capital Pte. Ltd. (Singapore) among others, as well as bank loans, and it is supposed to be ranked within the top ten largest startups in Japan. This puts our total funding value at US $200M (22.8 billion yen) since our founding.

The company plans to launch a constellation of 30 radar satellites by 2026, designed to do Earth resource observations.

Synspective had hoped to launch its first demonstration satellite in ’23 on a Soyuz rocket. That launch is presently threatened by Russia’s invasion of the Ukraine, though it is not clear if it has been cancelled.

China successfully launches Long March 6A for the first time

9:55 am

China today successfully completed the first launched of its Long March 6A rocket, upgraded significantly from earlier versions of the Long March 6.

The launch also debuted a new launchpad at China’s Taiyuan Satellite Launch Center in the country’s interior. The two payloads deployed appear to be technology tests, though China provided little information.

The launch of the Long March 6A also sported four solid rocket strap-on boosters. With these and the core first stage all crashing on land in China, there was no word whether any had any technology for controlling their landings.

The leaders in the 2022 launch race:

11 SpaceX
7 China
4 Russia
2 ULA

The U.S. now leads China 17 to 7 in the national rankings.

Ice sheets on Mars below 30 degrees latitude?

12:56 pm

Cracks in Ice on Mars?
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on November 29, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a collection of scattered thin surface fractures, grouped in clusters of parallel lines with the orientation of the clusters all somewhat random to other clusters.

The fractures, as well as the material inside the craters, appears to resemble glacial features, suggesting that these fractures are the result of either the past motion of the glacial sheet, or the sublimation of the buried ice, which causes it to crack and shrink as it slowly dissipates away.

The problem with that hypothesis is the location, as shown by the overview map below.

SpaceX to freeze its manned Dragon capsule fleet at four

9:12 am

Capitalism in space: According to SpaceX officials, the company is suspending construction on any further manned Dragon capsules, freezing its fleet at the four capsules they have now built, Endeavour, Resilience, Endurance, and Freedom.

“We are finishing our final (capsule), but we still are manufacturing components, because we’ll be refurbishing,” SpaceX President Gwynne Shotwell told Reuters, confirming the plan to end Crew Dragon manufacturing.

She added that SpaceX would retain the capability to build more capsules if a need arises in the future, but contended that “fleet management is key.”

This decision — to only use reused capsules — will of course give SpaceX to ability to lower its prices for manned tourist flights, but I doubt that will happen at this time because there isn’t anyone presently available who can compete. Instead, the company will rake in more profits.

The decision however does indicate SpaceX’s own assessment of the present space tourism market. If the company thought it needed more capsules in its fleet to match the demand, it would of course build them. Right now, it appears the company has decided four capsules is enough to cover NASA’s needs, as well as any additional private commercial flights. It also suggests SpaceX is anticipating the eventual arrival of Boeing’s Starliner into the mix, which will pick up some of the business that so far has belonged entirely to SpaceX.

Curiosity presently traveling over broken sandstone from an ancient dune field

10:27 am

Gator-back terrain on Mars
Click for full image.

According to a new paper, scientists now think that the rough and broken cap layer of the Greenheugh pediment that Curiosity is presently traveling across was originally a dune field periodically washed by water runoff, which with time eventually hardened into sandstone.

That broken terrain, dubbed “gator-back terrain” by the Curiosity science team, is shown clearly in the image to the right, taken on March 20, 2022. From the paper’s abstract:

The Greenheugh pediment is capped by a unit of broadly uniform thickness which represents the remains of the Stimson dune field that existed <2.5 Ga (mid- to late-Hesperian). ChemCam geochemical data shows that the sands deposited at the Greenheugh capping unit were sourced from a nearby olivine-rich unit. Surface waters then cemented the windblown sand deposits, ponding at the unconformity with the underlying mudstone unit, creating concretions towards the base. Episodes of groundwater circulation did not affect the rocks at Greenheugh as much as they did at other Stimson localities with the exception of acid-sulfate alteration that occurred along the unconformity. These results suggest that the ancient Stimson dune field was a dynamic environment, incorporating grains from the surrounding geological units on Mt Sharp. Furthermore, liquid water was stable at the surface in the Hesperian and was available for multiple diagenetic events along bedrock weaknesses.

In other words, material from Mount Sharp formed the dune fields, all of which were reshaped by groundwater circulation, with the dunes higher on the mountain seeing less groundwater.

The biggest uncertainty of these findings is explaining how surface liquid water could exist on Mars. Scientists have yet to develop an accepted model that would allow it. Another possibility would be the recent data that suggests Gale Crater was filled with glaciers. If so, scientists would need to figure out how the interaction of a Martian glacier might have geologically changed those dunes in a manner similar to groundwater.

ISRO pinpoints cause of August ’21 failure of India’s GSLV

9:59 am

India’s space agency ISRO has completed its investigation of the failure of the third stage of its GSLV rocket during an August ’21 launch, identifying a leaky valve as the cause.

The leakage in the Vent and Relief Valve is being attributed to the damage in the soft seal that could have occurred during the valve operations or due to contamination and valve mounting stresses induced under cryogenic temperature conditions.

“The committee has submitted comprehensive recommendations to enhance the robustness of the Cryogenic Upper Stage for future GSLV missions, which includes an active LH2 tank pressurization system to be incorporated to ensure sufficient pressure in the LH2 tank at the appropriate time before engine start command, strengthening of Vent & Relief Valve and associated fluid circuits to avoid the possibility of leakage along with the automatic monitoring of additional cryogenic stage parameters for giving lift-off clearance,” Isro said.

India entire space industry almost completely shut down for two years due to its panic over the Wuhan flu. This launch was part of its effort to resume launches, and the failure only added to that shutdown.

FAA again delays decision on environmental reassessment of SpaceX’s Boca Chica facility

1:32 pm

Surprise, surprise! According to an FAA email sent out today, the agency has once again, for the fifth time, delayed its decision on the environmental reassessment of SpaceX’s Boca Chica Starship launch site.

From the email:

The Federal Aviation Administration (FAA) is updating the release date for the SpaceX Starship/Super Heavy Final Programmatic Environmental Assessment (PEA) on the Federal Infrastructure Permitting Dashboard (Permitting Dashboard) and project website. The FAA plans to issue the Final PEA on April 29th. The planned April 29, 2022 release date will allow the FAA to review the Final PEA, including responses to comments, and complete consultation and coordination with agencies at the local, State, and Federal level. All consultations must be complete before the FAA can issue the Final PEA.

This date is now listed on the FAA’s SpaceX-Starship webpage. Nor is the decision a surprise. Expect the FAA to continue this charade month-to-month until after the November election, when the Biden administration will then feel free to block SpaceX’s effort in Boca Chica completely.

Ukraine War energizes commercial orbital remote sensing industry

10:31 am

Capitalism in space: It appears that the Ukraine War has had a positive effect on the emerging commercial remote-sensing satellite industry.

This industry is made up of a number of new private companies launching satellites to take high resolution images across a range of wavelengths, as well as do surveillance of communications. These companies have in the past decade slowly taken over this market from government satellites, which were becoming too expensive and launching too slowly to meet the military’s needs.

The war is illustrating their success, and firming up their businesses as other customers, such as news organizations, utilize their capabilities.

Solar Orbiter takes closest image of Sun so far

10:18 am

Solar Orbiter's closest image of the Sun, so far
Click for full interactive image, where you can zoom in, a lot.

Cool image time! The European Space Agency (ESA) yesterday released several new images from its Solar Orbiter probe, taken when the spacecraft made its most recent closest approach of the Sun.

One of the images, taken by the Extreme Ultraviolet Imager (EUI) is the highest resolution image of the Sun’s full disc and outer atmosphere, the corona, ever taken.

Another image, taken by the Spectral Imaging of the Coronal Environment (SPICE) instrument represents the first full Sun image of its kind in 50 years, and by far the best one, taken at the Lyman-beta wavelength of ultraviolet light that is emitted by hydrogen gas.

The images were taken when Solar Orbiter was at a distance of roughly 75 million kilometres, half way between our world and its parent star. The high-resolution telescope of EUI takes pictures of such high spatial resolution that, at that close distance, a mosaic of 25 individual images is needed to cover the entire Sun. Taken one after the other, the full image was captured over a period of more than four hours because each tile takes about 10 minutes, including the time for the spacecraft to point from one segment to the next.

The photo to the right, reduced to post here, is the EUI photo.

Solar Orbiter has been in its science orbit since November, though that orbit over time will slowly be adjusted to swing the spacecraft into a higher inclination so that it can make the first close-up observations of the Sun’s polar regions. It is also working in tandem with the Parker Solar Probe, which observes the Sun from even closer distances using different instruments.

Arianespace and SpaceX adjust to the new commercial launch market, without Russia

9:56 am

Link here. The article is mostly about how both companies need to adjust their launch schedules, with Arianespace scrambling to find rockets for its customers who had been scheduled to launch on Russian Soyuz-2 rockets and SpaceX describing how it will readjust its schedule with the addition of the OneWeb satellite launches.

The article had two quotes of interest. First, this fact about Arianespace’s new Vega-C rocket:

The Vega C uses an upper stage engine provided by Ukraine’s Yuzhmash, and supplies of that engine are in question because of the ongoing invasion. ESA officials said March 17 that they have three of those engines, enough to handle the anticipated Vega C missions this year.

ESA is supporting work on a new upper stage engine, M10, for a version of the Vega called Vega E that is slated to make its first launch around 2025. [Stéphane Israël, chief executive of Arianespace] said there was “no need” to accelerate work on Vega E, though, citing the Ukrainian engines in storage.

Thus, Vega-C is in the same boat as Northrop Grumman’s Antares, which also relies on Ukrainian rocket engines. When you also add the difficulty that both Blue Origin and ULA are having getting new rockets off the ground because of the delays in the BE-4 engine, it appears that in general there is presently a strong need across the entire rocket industry for rocket engines that is not being fulfilled by the engine builders available. This fact puts the new rocket engine company Ursa Major in a very strong position, should it begin to build bigger engines to serve this need. It also suggests there is an opportunity here for other engine builders, such as Aerojet Rocketdyne, if they have the wherewithal to grab it.

The second quote from the article of interest was from a SpaceX official, describing how the company is dealing with the sudden requirement to launch 216 OneWeb satellites:

Tom Ochinero, vice president of commercial sales at SpaceX, said at the conference that the company’s vertical integration and large fleet of reusable boosters offer the company flexibility to accommodate customers like OneWeb. “We can react very quickly because we’re just managing a fleet,” he said. [emphasis mine]

I just love the significance of the highlighted quote. Unlike all past rocket companies, SpaceX doesn’t have to build more rockets to add new customers, which makes adding new customers difficult and expensive. It simply can readjust how it uses the rockets in its fleet to get those new customers in orbit. And the new business will likely pay for SpaceX to expand that fleet so that it can launch more satellites even quicker.

Ingenuity completes 23rd flight on Mars

11:05 pm

Overview map
Click for interactive map.

JPL announced tonight in a tweet that Ingenuity today completed its 23rd successful flight on Mars.

23 flights and counting! #MarsHelicopter successfully completed its 23rd excursion. It flew for 129.1 seconds over 358 meters [1,175 feet].

The overview map to the right was taken from the “Where is Perseverance?” webpage and annotated by me to show the planned future routes of both Perseverance and Ingenuity. The white dotted line shows Perseverance’s path, now having almost circled the rough ground on its way to the delta and Three Forks. The tan dotted line indicates Perseverance’s future route. The dashed pink and green lines indicate two possible future flight paths for Ingenuity.

The green dot marks the position the science team marked on the map for where Ingenuity landed after today’s flight. They have not yet calculated the actual flight path, which is why it is shown by the tan dashed line. This also means there is as yet some uncertainty about this landing spot.

Originally, the plan had been to get to this spot in one flight. For reasons not yet explained, when the helicopter took off on its 22nd flight during the March 19-20th weekend, it stopped after only about 100 feet. Today’s flight apparently completed the plan, putting the helicopter where it was supposed to be.

SpaceX raises launch prices

10:55 am

Capitalism in space: Though most of the press has focused on the Starlink announcement on March 22nd that it was raising its subscriber rates, that same day SpaceX announced that it too was raising its prices, increasing its launch fees by 8% to 10%.

The starting prices for a Falcon 9 or Falcon Heavy rocket will each increase by about 8%. A Falcon 9 launch will cost $67 million, up from $62 million, and a Falcon Heavy launch will now run $97 million, up from $90 million. A footnote on SpaceX’s pricing page notes that “missions purchased in 2022 but flown beyond 2023 may be subject to additional adjustments due to inflation.”

..The company also adjusted its prices for its small satellite rideshare program. Those flights will now start at $1.1 million to fly a payload weighing 200 kilograms to a sun-synchronous orbit, up from a base price of $1 million. SpaceX increased the cost of additional payload mass by 10% as well and will now charge $5,500 per extra kilogram, up from a previous $5,000 per kilogram.

As with the Starlink announcement, SpaceX officials stated that the price increase was due entirely by inflation.

The irony here is that SpaceX could easily raise its rocket prices by 20%, and still be undercutting its entire competition. Even with these increases it is still by far the cheapest game in town.

Nonetheless, when it comes to inflation we have only just begun. The consequences of the Ukraine war, the sanctions against Russia, the Biden administration’s restrictions on domestic oil production, and the various COVID regulations restricting commerce are all still in effect, and are all putting pressure on supply. Prices will continue to rise.
