Japan awards $32.5 million contract for lunar GPS-type satellite constellation to startup

9:52 am

Capitalism in space: As part of the multi-billion dollar fund the Japanese government has allocated to encourage private enterprise by new Japanese startups, its space agency JAXA has now awarded a $32.5 million development contract to the startup ArkEdge Space to design and fly a GPS-type satellite in orbit around the Moon, thus demonstrating the technology.

Under the agreement, ArkEdge Space will plan and design the mass production and operation of micro-satellite constellations to lead the development of a next-generation Lunar Navigation Satellite System (LNSS), a vital component to the International “LunaNet” initiative driven by National Aeronautics and Space Administration (NASA), European Space Agency (ESA) and JAXA. LunaNet seeks to establish essential infrastructure to support sustainable lunar exploration and foster the growth of the lunar economy.

The real significance of this contract award is that it signals JAXA’s growing shift from designing, building, and owning everything to simply becoming the customer who gets what it needs from the private sector. The Japanese government had established that fund for this express purpose, but JAXA has shown a reluctance to proceed, as it directly threatens its turf. This award indicates that reluctance is finally being pushed aside.

Orbex gives up on the Sutherland spaceport, switches to SaxaVord

9:27 am

In a very sudden decision, the rocket startup Orbex, based in Great Britain, has “paused” its long-delayed work to develop a launch facility at the Sutherland spaceport in northern Scotland and instead decided to launch its first rockets from the competing SaxaVord spaceport on the Shetland islands.

Orbex says it is halting construction work on the £20 million spaceport and instead is mothballing the project, which has received a £14.6 million public investment package. The space company, which was to have made the Sutherland Spaceport its home port, will now launch its rockets carrying commercial satellites from another north spaceport – SaxaVord on Unst, Shetland.

According to the company’s CEO, it will retain its 50-year lease at Sutherland to give it “flexibility to increase launch capacity in the future.”

The company had originally hoped to launch its Prime rocket from Sutherland in 2022, but has been faced with red tape from the Civil Aviation Authority (CAA), which has still not issued a launch licence, even though the application was submitted almost three years ago. Orbex has also faced lawfare opposition from local activists as well as a major local landowner, billionaire Anders Povlsen, who is also a major investor in SaxaVord.

That last detail might help explain this decision. In private talks Orbex might have learned that the red tape and opposition would disappear if it switched to SaxaVord. The timing is also suggestive, as only a few days ago construction started on a new spaceport in Scotland, located on the island of North Uist.

All told, Orbex might have decided that the stars were aligned against it at Sutherland, and it was better to move. It now hopes to complete the first test launch of its Prime rocket from SaxaVord next year.

Two launches completed of the seven launches expected in the next 24 hours

9:04 am

Today will be one of the busiest ever at spaceports worldwide. Already we have had two launches, with five more expected by this time tomorrow.

First, China launched a radar satellite, its Kuaizhou-1A solid-fueled rocket lifting off from the Xichang spaceport in the southwest of China. No word on where the rocket’s lower stages crashed in China.

Next, SpaceX placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida in the early morning hours. The first stage completed a record 24th flight, the most flights of any Falcon 9 booster so far, landing on a drone ship in the Atlantic Ocean.

And we are only getting started today. If all goes right, by this time tomorrow Russia will have done a military launch from its Plesetsk spaceport, Arianespace will have launched a Vega-C from French Guiana, SpaceX will have completed two more Falcon 9 launches from Vandenberg and Kennedy, and India will have launched its PSLV rocket from its Sriharikota spaceport.

The leaders in the 2024 launch race:

125 SpaceX
58 China
15 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 144 to 86, while SpaceX by itself leads the entire world, including American companies, 125 to 105.

SpaceX looking to raise more private investment capital

3:47 pm

According to a report yesterday by Bloomberg, SpaceX is now in talks to raise more private investment capital, based on a new and vastly increased valuation of the company, from $255 billion to $350 billion.

A so-called tender or secondary offering, through which employees and some early shareholders can sell shares, provides investors in closely held companies such as SpaceX a way to generate liquidity.

The amount the company hopes to raise by this tender is at present not known. In the past decade the company has raised about $12 billion in private capital in order to fund development of both its Starship/Superheavy rocket as well as its Starlink internet constellation. The latter however is already generating about $9 billion in revenue annually in the past two years, more than enough to fund the projects.

Perseverance on the verge of leaving Jezero Crater

12:44 pm

Looking up to Lookout Hill

Overview map
Click for interactive map.

Since landing on Mars in 2021, the rover Perseverance has been exploring Jezero Crater, first the crater floor and then the delta that poured into the crater through a western gap.

Now, after three years of exploration and the drilling of 25 core samples, the science team is about to send Perseverance over the top of the crater’s western rim, to explore the very mountainous but potentially rich mining region beyond.

The blue dot on the overview map to the right indicates the rover’s present position, with the area covered by the panorama above, taken on November 26, 2024 by Perverance’s left navigation camera and cropped and annotated to post here, indicated by the yellow lines.

The red dotted line indicates the rover’s planned route. The black dotted line is a former plan that apparently has now been abandoned. It appears the science team really wants to check out Witch Hazel Hill, as well as reach the rim’s highest point to get views of its future travels. From an update posted yesterday:

Orbital views of Witch Hazel Hill suggest the area may contain layered and light-toned bedrock that likely record important information of the planet’s ancient climate. Prior to arriving at Witch Hazel Hill, the rover plans to pass through a high point known as Lookout Hill that will afford the team incredible views looking back into the crater, as well as get a glimpse westward of terrain far beyond Jezero.

The region beyond Jezero is hilly and rough. The views should be quite interesting.

PLD obtains a new loan, this time for $11.6 million

11:45 am

The Spanish rocket startup PLD yesterday announced it has obtained a new $11.6 million loan that it plans to use to build its launch facility at the French-owned French Guiana spaceport.

The loan was issued by the Spanish governmment finance agency COFIDES, which comes on top of an earlier $43.8 million Spanish government grant. In addition, the company has gotten a $2.4 million grant from the European Commission, as well as a $1.37 million grant from the European Space Agency.

The company has also obtained a loan of $34 million from banks in Spain.

All told, the company has raised about $164 million, more than $58 million came from government agencies, with another $34 million from loans.

For whatever reason, PLD has found favor with the various governments in Europe, fueling its work. None of the other European rocket startups from Germany or Great Britain have been as lucky.

Analysis of Chang’e-6’s lunar samples suggest the giant impact that caused Aitken Basin occurred 2.83 billion years ago

10:33 am

Chang'e-6's landing site

In a paper published in mid-November, Chinese scientists have concluded that — based on their analysis of the lunar samples returned by their Chang’e-6 spacecraft — the giant impact that created the 1,600-mile-wide South Pole-Aitken Basin on the Moon occurred about 2.83 billion years ago.

This conclusion is based both on the dating of the samples as well an analysis of the cratering rate on the Moon. It also suggests the landing site as well as Aitken basin were volcanically active for longer than previous predictions. Overall, scientists believe most volcanic activity on the Moon ceased around three billion years ago.

As noted in the paper, the near and far sides of the Moon are very different.

The Moon has a global dichotomy, with its near and far sides having different geomorphology, topography, chemical composition, crustal thickness, and evidence of volcanism. Volcanic eruptions flooded parts of the surface with lava, producing rocks known as mare basalts, which are more common on the nearside (4), where they cover ~30% of the surface compared to 2% of the farside.

The farside’s crust is also thicker, though under Aitken Basin the difference largely disappears.

This first precise dating for the far side is the first step for understanding why the Moon’s hemispheres are so different. Though many theories exist, none can be considered definitive because we so far have only one data point for the far side.

The uncertainty of science: Star refuses to erupt when predicted

9:48 am

Based on records of two past eruptions approximately eighty years apart, astronomers had predicted that the binary star system T Coronae Borealis would erupt sometime in September 2024, brightening from magnitude 10 to as much as magnitude 2, making it one of the sky’s brighter stars for a short while.

That eruption however has so far not taken place.

“We know it has to happen,” astrophysicist Elizabeth Hays, who is watching T CrB every day using NASA’s Fermi gamma-ray space telescope, told Space.com in a recent interview. “We just can’t pin it down to the month.”

The unpredictability stems partly from limited historical records of T CrB’s outbursts. Only two such eruptions have been definitively observed in recent history: on May 12, 1866, when a star’s outburst briefly outshined all the stars in its constellation, reaching magnitude 2.0, and again on February 9, 1946, when it peaked at magnitude 3.0. These events appear to follow the star’s roughly 80-year cycle, suggesting that the next outburst may not occur until 2026. [emphasis mine]

The eruptions are thought to occur because the system’s denser white dwarf star pulls material from the lighter orbiting red giant. Over time that material accumulates on the surface of the white dwarf until it reaches critical mass, triggering a nuclear explosion that we see as the star’s brightening.

Astronomers have assumed this process is predictable, but in truth it really is not. For example, the star has brightened at other times, in 1938 and again in 2015, though not as much. These other brightenings suggest a great deal of uncertainty in the rate in which material accumulates, as well as how much is needed to trigger a nuclear burst.

Because of the possibility however of a burst at any time, astronomers have been poised eagerly now for months, observing the star regularly with the many orbiting telescopes that can observe it not only in optical wavelengths but in gamma, X-rays, and infrared. The latter capabilities didn’t exist in previous eruptions, and are now able to tell them things about the system that was impossible for earlier astronomers.

Assuming the eruption occurs at all. Despite the certainty of the astronomer’s quote highlighted above, there is no certainty here. This star system will do whatever it wants, despite the predictions of mere human beings.

Varda wins $48 million Air Force contract

9:29 am

Varda's space capsule, on the ground in Utah
Varda’s first capsule on the ground in Utah.

The U.S. Air Force last week awarded the reusable orbiting capsule company Varda a four-year $48 million contract for placing experimental hypersonic payloads on the capsule for testing during its re-entry through the atmosphere.

The four-year deal with AFRL [Air Force Research Laboratory], announced on Nov. 26, leverages Varda’s W-Series reentry capsules as platforms to test payloads at hypersonic speeds. The spacecraft are built on Rocket Lab’s Photon satellite bus,

…Varda’s next mission, W-2, is scheduled for early 2025. This mission is designed to showcase the Varda Hypersonic Testbed vehicle. The capsule will carry an AFRL-developed spectrometer payload named OSPREE (Optical Sensing of Plasmas in the Reentry Environment) to collect critical data during atmospheric descent.

Up until now Varda’s customers have been entirely focused on using the capsule to produce pharmaceuticals in weightlessness for sale back on Earth. This new contract provides it another and initially unexpected way to make money on the capsule’s capabilities.
