Space Perspective needs new investors

9:50 am

According to this news article today, the high altitude balloon company Space Perspective is in need of new investment capital, and its apparent lease default in the Cape Canaveral area is because the company has apparently shifted operations about ninety miles south because costs there are lower.

Space Perspective co-founder Jane Poynter told OBJ in a Zoom interview in December that although Port Canaveral “is our home port” and “we’re very committed to the community we work in” the company had been operating out of Fort Pierce, nearly 90 miles south, for several months. “They are having to struggle with how they balance what’s happening with the cruise industry and space industry growing like gangbusters,” she said of the Space Coast. “It’s so congested that we can’t actually stay there.”

While the company claims it is still moving forward, it has had to lay off most of its staff as it tries to find more investment capital. While it also claims it will return to full staffing when that investment arrives, the question is whether it will arrive. At this moment the default of $90,295 in rent to Titusville-Cocoa Airport Authority is not a good look at all.

AST SpaceMobile raises $400 million in capital

9:33 am

The direct-to-cell satellite company AST SpaceMobile has raised another $400 million in investment capital, giving it a total of $900 million in cash on hand for building its full constellation of its much larger second generation Bluebird satellites.

The operator now has more than $900 million of cash on its balance sheet to shift production of its Block 2 BlueBird satellites into a higher gear this year, after deploying five smaller Block 1 spacecraft to low Earth orbit (LEO) in September.

At about 223 square meters when fully deployed, a Block 2 satellite is significantly larger than Block 1, which spans 64 square meters, enabling 10 times the capacity to support up to 120 megabits per second (Mbps) peak data rates.

It has plans to launch 45 of these larger satellites in the next two years.

At the moment AST SpaceMobile and SpaceX are the only two companies offering direct-to-cell service. One component of SpaceX’s Starlink constellation has this capability, and the company has a deal with T-Mobile to use it to fill in gaps in its cell tower ground network. AST in turn has a deal with AT&T.

Report predicts both Boeing and Airbus will sell off their space divisions this year

9:23 am

According to an analysis of industry trends by the company Space Capital, it predicts that both Boeing and Airbus will sell off their space divisions this year.

According to Space Capital’s latest investment trends report released Jan. 23, these aerospace giants are struggling to maintain pace with the rapidly evolving space sector. “These divestitures by entrenched government contractors marks a pivotal moment in the space economy, as it changes the competitive landscape, establishes a new power broker system, and creates new opportunities and risks in the government’s extended capabilities in space,” the report states.

This prediction for Boeing is not a surprise, especially as the company has also recently announced it expects to take a $1.7 billion loss in the fourth quarter of 2024 from five different program in its Defense, Space and Security business unit.

Most of those charges will go towards two programs: $800 million for the KC-46A tanker and $500 million for the T-7A trainer aircraft. That leaves $400 million in charges for Starliner as well as the VC-25B presidential aircraft and MQ-25 drone.

Airbus’s space division is likely in trouble because of the failure of its Ariane-6 to compete successfully in the modern launch market. It has obtained some launch contracts, but not as many as expected because, as an expendable rocket, it costs too much to launch.

Peeling flood lava on Mars

12:09 pm

Peeling flood lava on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “enigmatic terrain” because its origins are a bit difficult to decipher. The location is just north of the equator, so this is in the dry tropics of Mars, where no near-surface ice is found at all. The location is also in the middle of Elysium Planitia, one of the largest flood lava plains on Mars. Elysium is a largely featureless flat plain, where flood lava from the large giant Martian volcanoes covered a vast region.

Here however that top layer of flood lava appears almost like peeling paint that failed to stick to the underlying rougher terrain. In many places it is gone, exposing a stippled surface that is also likely flood lava but laid down either in a rougher manner or eroded over time to leave a rougher surface.

Rocket Lab wins launch contract with German satellite constellation

8:58 am

Rocket Lab has won a launch contract with the German satellite constellation Orora Technologies,with the launch to occur only four months hence and place eight satellites into orbit.

The constellation is focused on monitoring wildfires for fire-fighting teams, and will eventually have 100 satellites in orbit.

OroraTech is developing a constellation of satellites with thermal infrared cameras that can provide 24/7 monitoring of wildfires globally, supporting better and faster wildfire response to protect forests, people, and infrastructure worldwide. The mission will deploy its latest plane of satellites called OTC-P1 to their current constellation, further expanding OroraTech’s capabilities to first responders, governments, and industry partners. The company will expand their constellation with up to 100 satellites in total by 2028.

If this launch goes as planned, expect Rocket Lab to win launch contracts for the rest of the constellation, a minimum of 11 more launches.

China launches 6th group of 18 satellites for its Spacesail internet constellation

8:52 am

China late yesterday successfully launched the sixth group of 18 satellites for its Spacesail internet constellation, its Long March 6A rocket lifting off from the Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages crashed inside China. The state-run report however touted proudly how the rocket uses liquid oxygen and kerosene, both of which are “non-toxic and pollution-free”. Apparently it has recognized the bad press it has gotten from crashing stages inside China that use very toxic hypergolic fuels.

The article noted that China plans at least ten launches in 2025 of the Long March 6A, likely as part of building this constellation of more than 1,200 satellites.

Blue Ghost completes first main mid-course correction engine burn

10:22 am

Firefly’s Blue Ghost lunar lander has not only successfully completed its first major engine burn, raising its Earth orbit as it slowly moves towards the Moon, but successfully used a joint NASA-Italian instrument to pinpoint its location using Earth-orbiting GPS-type satellites.

Jointly developed by NASA and the Italian Space Agency, the Lunar GNSS Receiver Experiment (LuGRE) technology demonstration acquired Global Navigation Satellite System (GNSS) signals, and calculated a navigation fix at nearly 52 Earth radii: more than 205,674 miles (331,000 kilometers) from Earth’s surface. This achievement suggests that Earth-based GNSS constellations can be used for navigation at nearly 90% of the distance to the Moon, an Earth-Moon signal distance record. It also demonstrates the power of using multiple GNSS constellations together, such as GPS and Galileo, to perform navigation.

These results suggest that if all lunar orbiters had this instrument on board, they could all pinpoint their positions precisely and thus eliminate the chance of collision. It also suggests that it might not be necessary, at least immediately, to build a separate GPS-type constellation around the Moon. Earth’s systems could do the job.

Blue Ghost will spend 25 days in Earth orbit, when it will transfer to lunar orbit for several more weeks before attempting a landing.

South Korea’s space bureaucracy attempts to encourage private sector development

9:38 am

South Korea’s space agency, the Korea Aerospace Administration, has announced a new effort to encourage that country’s private sector in developing rockets and satellites.

[A] plan will be established to link the National Space Council, the highest policy decision-making body overseeing government space policy, with the Aerospace Development Policy Review Committee. Systems will also be established for workforce training in aerospace and the designation of a space development mission center.

To establish an aerospace economic ecosystem, the participation of the private sector in the development and utilization of launch vehicles and satellites will be expanded. In the aviation sector, future aircraft technologies, including urban air mobility (UAM), will be secured, and localization of aircraft materials and components will be supported. To encourage smooth research and development (R&D) investments in aerospace corporations, the aerospace fund will be revitalized with improvements to regulations and support for overseas expansion.

Overall, a lot of this sounds like meaningless bureaucratic gobbledygook. The goal might be to expand the private sector, but the program still has the space agency running everything, from its new government-built Nuri rocket to its other satellite development programs.

Nonetheless, the desire to encourage the private sector is good. It could simply be that South Korea’s private sector is not mature enough yet to take the lead, and the agency by this announcement is working to push it forward.

General Atomics successfully tests fuels to be used in an in-space nuclear propulsion system

9:16 am

The company General Atomics announced yesterday that it has successfully tested the fuels it wants to use in an in-space nuclear propulsion system for transporting ships to the Moon and beyond much faster and more efficiently than is presently possible with chemical engines.

[General Atomics] executed several high-impact tests at NASA’s MSFC in Huntsville, AL. The nuclear fuel was tested with hot hydrogen flow through the samples and subjected to six thermal cycles that rapidly ramped-up to a peak temperature of 2600 K (Kelvin) or 4220° Fahrenheit. Each cycle included a 20-minute hold at peak performance to demonstrate the effectiveness of shielding the fuel material from erosion and degradation by the hot hydrogen. Additional tests were performed with varying protective features to provide further data on how different material enhancements improve performance under reactor-like conditions.

It has been known since the 1960s the nuclear propulsion is more efficient that chemical engines. It can burn for longer time periods at higher levels, thus making it possible to get to other planets more quickly, in some cases bypassing the need to depend on orbital mechanics.

The problem however has been political. Getting these nuclear engines into orbit has been too much of a political hot potato. The fear of such engines and radioactivity, largely irrational, has made it impossible to get them built. NASA is now trying again.

Japan’s government wants its private sector to do all its future space station work, not its space agency JAXA

9:05 am

In a major shift of power away from its government, the Japanese science and technology ministry is presently drafting a policy that would have that country’s private sector lead all work that Japan does on any of the future commercial private space stations being built, not its space agency JAXA as has been done now for decades.

The draft policy specifies how Japan will be involved with the next space station. According to the draft, “the private sector will have such responsibilities as managing [the new space station], and JAXA will support its use.”

JAXA is currently responsible to the management and maintenance of the ISS and serves as the point of contact for its commercial use. However, the government will select a Japanese private-sector company to be the point of contact for the next space station. When JAXA, research institutes or other companies plan to use the ISS, they will have to contact the next station’s point of contact.

While Japan wants to have one of its own modules on one of the commercial stations, as it presently has on ISS, it appears the government does not want JAXA to lead this project. Instead, it wants Japan’s private sector to run the show by working out its own deals with the private commercial stations. At present the Japanese company Mitsui is partnering with Axiom on its station, so this is likely the first station where a deal could be worked out.

It seems that Japan is trying to poke its private sector out of its doldrums. Right now that sector seems unable to take any action on its own. It sits and waits for guidance from the government before acting, and even then acts timidly, waiting to see if the government approves of each step. What the Japanese government now wants instead is some independent action, not linked to government policy.

Trump picks Janet Petro of Kennedy to be acting NASA administrator, not Jim Free of headquarters

8:41 am

In a surprise move, the Trump administration announced yesterday that the expected person to take over as acting administrator of NASA until Jared Isaacman is approved by the Senate would not be Jim Free. the present associate administrator at NASA headquarters, but Janet Petro, who is presently director of the Kennedy Space Center.

NASA had so much assumed Free had the job that it had already listed him as acting administrator today on the NASA webpage.

There has of course been speculation as to why Trump made this unexpected choice. My guess is that Trump wants to reduce significantly the size of NASA headquarters, and thus wants someone from outside to run it for the present. Petro has been at Kennedy since 2007. Before that she was in the private sector.

Free has been a working out of DC for several years, and thus has stronger ties to the workforce there.

The decision also makes it clear to the NASA bureaucracy who is in charge. Decisions will no longer be made by that bureaucracy without strong input from Trump.

Meandering channel inside a larger glacial-filled valley

12:39 pm

A meandering channel
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on October 9, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “Channel in North Warrego Valles,” referring to the meandering channel on the left side of the picture. Note the stippled look of the surrounding terrain. This surface appears to be brain terrain, an as-yet unexplained feature on Mars that is always associated with near-surface ice features.

This location is at 40 degrees south latitude, placing it in the mid-latitudes where lots of glacial features are often found on Mars. Thus, it shouldn’t be surprising to find at this location brain terrain, or a meandering channel. The location however is a bit unusual, and reinforces once again that there is a lot of near-surface on Mars, readily available, as long as you are above 30 degrees latitude north or south.

Did a high altitude Grasshopper rocket test last week by China fail?

9:18 am

According to this report from Space News, a high altitude grasshopper-type vertical ascent-descent rocket test that China attempted on January 18, 2025 appears to possibly have been a failure.

Longxing-2 is thought to be a test article for the Long March 12A reusable launcher being developed by the Shanghai Academy of Spaceflight Technology (SAST). The rocket was designed to replicate the first stage of a reusable flight, reaching around 75 kilometers before performing a reentry burn and making a powered descent and splashdown into the Yellow Sea.

Amateur footage captured from near the launch area showed the rocket rise very slowly from the tower and perform an ascent phase with no apparent anomalies. The test was intended to build on a successful 12-kilometer-altitude vertical takeoff, vertical landing (VTVL) test performed in June 2024.

SAST published results and footage from the June test, but has so far remained silent on the 75-km attempt, being yet to publish any results or details of the flight more than 24 hours after liftoff. The lack of official updates raises questions about the success of the test, which could indicate challenges during reentry or landing phases.

It is also possible that the soft splashdown landing was a success and China is simply being its normal secretive self and refusing to release any information.

Chinese pseudo-company completes launch

9:09 am

The Chinese pseudo-company Galactic Energy today completed its first launch in 2025, its solid-fueled Ceres-1 rocket lifting off from the Jiuquan spaceport in northwest China. It place five satellites in orbit, four for weather and one for Earth observation.

Meanwhile SpaceX yesterday had to scrub a Starlink launch from Vandenberg yesterday at T-11 seconds because an airplane had entered the launch range by mistake. It will try again in a few hours [UPDATE: Now scrubbed till tomorrow], and then follow up with another Starlink launch just after midnight tonight from Kennedy.

Overview map
Click for interactive map.

Andrew Bodrov from Mars360 has created another 360 degree mosaic using 854 high resolution images taken by the rover Perseverance when it stood at Lookout Hill, at the top of the rim of Jezero Crater. I have embedded it below. From his announcement:

The panorama provides a complete view of Perseverance, allowing you to examine its intricate design in incredible detail. Every component is visible, showcasing the engineering brilliance that powers this groundbreaking mission.

The Martian terrain stretches out around the rover, with its tracks cutting a path into the distance. The Jezero Crater rim, visible on the horizon, features rugged rock formations and textured sands that add depth to this remarkable scene.

The overview map to the right provides the context. The view begins by looking south, at the crater rim. If you rotate to the left you will see the tracks of Perseverance, indicating its previous travels, and then the rim to the north. Next the view looks outside the crater to the west.

Has the tourist balloon company Space Perspective gone belly-up?

1:28 pm

Space Perspective's Neptune Capsule
Space Perspective’s Neptune balloon capsule

According to the local paper Florida Today, the high altitude tourist balloon company Space Perspective owes more than $90K rent on its facility at Florida’s Space Coast Regional Airport, and has apparently ceased activity in mid-December.

Activity appears to have largely ceased at Space Perspective’s “Mission Control” office building at the Titusville airport, where the facility has appeared largely unoccupied the past two weeks. Nobody answered the doorbell during a trio of FLORIDA TODAY visits since Jan. 6, and no vehicles were in the parking lot just before 1 p.m. Wednesday.

FLORIDA TODAY has left messages unsuccessfully attempting to contact Space Perspective executives. One vehicle was parked in the Mission Control lot Tuesday afternoon, and an employee answered the doorbell. A FLORIDA TODAY reporter passed along a written message seeking comment from company officials.

Another source notes that numerous former employees in recent weeks have been looking for new jobs in the Florida region.

The Florida Today article also documents several other cases where the company had had problems paying its bills.

It is possible the company is dead. There is also the possibility that it remains alive, but has decided to skip town because it is now setting up operations in the Middle East. In one of its last major announcements in November 2024 it revealed it is in negotiations with a number of Middle Eastern nations for flying balloon flights there.

All in all this story is very puzzling. The company had already built its Florida factory for making its balloons, and had done one test flight of a prototype manned capsule for tourist flights. It seemed poised to begin commercial operations. To shut down so suddenly now suggests a lot of things, some of which could indicate some very dishonest motives indeed.

Hubble’s biggest image yet, of Andromeda

12:14 pm

Andromedia as seen by Hubble
Click for original image.

The image above, cropped and reduced to post here, was taken by the Hubble Space Telescope and shows the Andromeda galaxy, the Milky Way’s nearest spiral galaxy neighbor. The picture however is not one photo, but hundreds taken over the past decade.

This is largest photomosaic ever assembled from Hubble Space Telescope observations. It is a panoramic view of the neighboring Andromeda galaxy, located 2.5 million light-years away. It took over 10 years to make this vast and colorful portrait of the galaxy, requiring over 600 Hubble overlapping snapshots that were challenging to stitch together. The galaxy is so close to us, that in angular size it is six times the apparent diameter of the full Moon, and can be seen with the unaided eye.

Andromeda is not just visible to the naked eye, it is one of the largest objects seen in the sky. If you ever can get to a really dark sky location when it is above and have someone point it out to you (it remains faint), you will be astonished to find that it stretches across the sky the length of about six to eight full moons.

Thus, Hubble literally can’t take a picture of it. Its field of view is much too small. It must take many pictures to assemble a mosaic.

The picture above also hides the data contained in all those images. At the full resolution of each individual picture, Hubble has literally mapped the entire galaxy. Combined with other spectroscopic survey data taken by Hubble, astronomers over time will be able to decipher the galaxy’s makeup to better understand its formation history.

U.S and Norway sign deal to allow U.S. companies to launch from Andøya

10:18 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The U.S. and Norway have now signed an agreement that will make it possible for American rocket and satellite companies to launch from Norway’s Andøya Spaceport, easing State Department rules that up until now made such launches difficult if not impossible.

[The Technology Safeguards Agreement (TSA)] will ensure the protection of U.S. technology, enabling the transfer of commercial launchers to Norway. Similar agreements have been established between the U.S. and other allied nations, including Australia, New Zealand, and the United Kingdom.

Right now Andoya has only two rocket customers, the German startup Isar Aerospace and a Polish suborbital startup, SpaceForest. Both hope to do launches sometime this year. Unlike the red tape that the United Kingdom has imposed on its new spaceports, Norway appears to be doing everything it can to grease the wheels so that launches can occur quickly and on schedule.

Starship lost near end of its orbital burn; Superheavy successfully captured by chopsticks

4:06 pm

Superheavy captured for the second time
Superheavy captured for the second time

In today’s seventh test flight of SpaceX’s Starship/Superheavy large rocket, the results were decidedly mixed.

First the success: Superheavy once again performed perfectly, getting Starship up to speed and releasing it for its orbital flight. It then successfully returned to the tower at Boca Chica, where the chopsticks arms caught it. This was the second catch in three attempts. While we should all expect SpaceX to continue to refine Superheavy, right now it appears to be largely ready to go.

Next the failure: Shortly after stage separation Starship fired its own engines and proceeded upward towards orbit. At one point close to when it was suppose to shut off its engines to begin its orbital coast phase, something went wrong. Some engines cut off, but one did not, at least according to data projected on the screen. At that point all telemetry from the ship ended.

After another ten minutes of analysis flight controlers declared the ship lost. What happened remains unclear, but it is certain SpaceX engineers are digging hard to find out.

One unfortunate question remains that must be asked: Where is the ship, and is there a chance it will come down somewhere unexpected? Its orbit is such that it will naturally fall in the Indian Ocean, but the engine issues might have changed that orbit somewhat.

UPDATE: Locals in the Turks and Caicos Islands in the Caribbean post videos on X (here and here) of Starship breaking up overhead. It appears that if any debris reaches the ground it will land in the Atlantic.

Live stream of the 7th test orbital flight of Starship/Superheavy

1:50 pm

I have embedded below the live stream of today’s attempt by SpaceX to complete the 7th orbital flight of its giant rocket Starship/Superheavy. The stream goes live at around 3:15 pm (Central), 45 minutes before the start of the one hour launch window beginning at 4 pm (Central).

For embed purposes I am using the youtube version provided by Space Affairs. Once SpaceX’s feed goes live on X you can then switch to it, found here.

The flight’s goals:

Superheavy: Complete the second catch of the booster at the launch tower using the chopsticks. The booster will also be reusing an engine from the fifth test flight to confirm its viability for reuse.

Starship: Test new avionics, a new fuel feed system, and new heat shield tiles as well as the ablative material used underneath the tiles. Test a different placement and configuration of the flaps. The ship will also test engineering that will eventually lead to it being captured by the chopstick tower on return.

There will be an engine restart during Starship’s orbital cruise phase to further confirm the Raptor-2 engines can work reliably when needed during a full orbit de-orbit burn.

Finally, the ship will test its Starlink deployment system, releasing 10 dummy Starlink satellites.

One Martian ridge among many

One Martian ridge among many
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 30, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is labeled as a “terrain sample,” so it was likely taken not as part of any specific research project but to fill a gap in the camera’s schedule.

The subject this time was a series of parallel ridges. I have cropped the image to focus on the most distinct, which stands at its highest about 600 feet below the dune-filled hollows to the north and south. The streaks on its flanks are likely slope streaks, a phenomenon unique to Mars that is presently not entirely understood. Streaks appear like avalanches, but they do not change the topography at all, and in fact in some cases go up and over rises. It is believed they are related to dust events, but this is not yet confirmed.

Why focus on this ridge however? It isn’t as if this is the most stunning geology on Mars.

Rocket Factory Augsburg gets conditional licence for launching at Saxavord

11:00 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

After years of delays and multiply approvals that in the end turned out to be meaningless, the United Kingdom’s Civil Aviation Authority (CAA) announced today that it has finally issued a launch license to the German rocket startup Rocket Factory Augsburg to do an orbital test launch from the Saxavord spaceport in the Shetland Islands.

The license however is not entirely without strings.

The licence is effective immediately, but a number of conditions need to be met before a launch can take place — including insurance arrangements and international agreements. The company is also required to give the CAA 60 days’ notice before launching.

Rocket Factory had hoped to launch last year, but it lost its RFA-1 rocket during a static fire test in August. It was planning a subsequent launch on the assumption the CAA would approve its licence in 2024. That assumption was wrong however. Even if the rocket had not been destroyed and was ready to go, the CAA was not, and continued to twiddle its thumbs until 2025. It is this twiddling that caused another German rocket startup, Hyimpulse, to abandon its plans to do launches from Saxavord, and switch to a new spaceport in Australia.

Rocket Factory now says it will attempt its first launch before the end of this year. Let’s see if the CAA lets that happen.

Firefly has announced that all is well with its Blue Ghost lunar lander, now in an ever expanding Earth orbit on its way to the Moon. Engineers have acquired signal and completed its on-orbit commissioning.

With a target landing date of March 2, 2025, Firefly’s 60-day mission is now underway, including approximately 45 days on-orbit and 14 days of lunar surface operations with 10 instruments as part of NASA’s Commercial Lunar Payload Services (CLPS) initiative.

…Firefly’s Blue Ghost will spend approximately 25 days in Earth orbit, four days in lunar transit, and 16 days in lunar orbit, enabling the team to conduct robust health checks on each subsystem, calibrate the propulsion system in preparation for critical maneuvers, and begin payload science operations.

NASA today released the first picture downloaded from the spacecraft, shown to the right. The view looks across the top deck of the lander, with two NASA science instruments on the horizon.

Once it lands it is designed to operate for about two weeks, during the lunar day. It will attempt to further gather some data during the long two-week long lunar night, but is not expected to survive to the next day.

Stoke Space raises another $260 million, more than doubling its private capital

10:22 am

Stoke's Nova rocket
Stoke’s Nova rocket

The rocket startup Stoke Space, which is attempting to develop its own fully reusable two stage rocket, announced yesterday that it has successfully raised $260 million of private investment capital in its most recent funding round, more that doubling what it had raised previously and bringing the total raised by the company to $480 million.

The funding round involves new and existing investors including Breakthrough Energy Ventures, Glade Brook Capital Partners, Industrious Ventures, Leitmotif, Point72 Ventures, Seven Seven Six, the University of Michigan, Woven Capital, and Y Combinator, among others.

The company’s Nova rocket will use what has become the standard for first stage re-use, a vertical take-off and landing. Its second stage however will also be reusable, something no one has yet succeeded in doing, and Stoke intends to do it in a radical manner. Rather than use a single nozzle on its upper stage, it has instead gone with a new design whereby thrust is released through a string small nozzles placed in a ring on the bottom outside of the stage. The base of the stage can thus get a heat shield. The plan is to have the stage return much like many returnable capsules, with the small nozzles then used to provide control and thrust during landing.

This new influx of cash indicates renewed confidence in the company among the investor class. Its recent successful test of its Zenith first stage engines probably help fuel that confidence.

It had hoped to do its first test launch this year from Cape Canaveral, but has recently been burdened with new environmental red tape that might impact those plans.

India’s Spadex mission completes docking

10:07 am

India’s space agency ISRO today announced that its engineers had successfully completed the autonomous docking of its two Spadex satellites, the chase vehicle making proper contact with the target vehicle and then linking together.

Manoeuvre from 15m to 3m hold point completed. Docking initiated with precision, leading to successful spacecraft capture. Retraction completed smoothly, followed by rigidisation for stability. Docking successfully completed

The docking needed to be completed before January 20th or the lighting conditions would have caused a delay until March.

Next engineers will demonstrate the spacecraft have linked electronically. Eventually they will then undock and spend up to two more years in orbit operating separately.

Blue Origin successfully launches New Glenn

12:35 am

New Glenn 18 seconds after liftoff
New Glenn 18 seconds after liftoff

Better late than never! After almost a decade of development and five years behind schedule, Blue Origin tonight successfully launched its massive New Glenn orbital rocket, placing its second stage into orbit carrying a demo version of the company’s Blue Ring orbital tug.

It appears the first stage had a problem during what Blue Origin calls its “booster reentry burn”, which appears somewhat equivalent to SpaceX’s entry burn. Unfortunately no camera views were made available. From that point no further telemetry came down from the first stage, suggesting something had gone wrong enough to require initiation of the flight termination system so the stage would not crash on the landing barge.

The second stage will operate in orbit for six hours, testing Blue Ring.

For Blue Origin this success, though late, is a grand achievement. The company has a full launch manifest, with a 27-launch contract with Amazon for its Kuiper internet constellation. It also has a deal with the Space Force to get the rocket certified for military launches, once it completes two successful launches. Once certified the Space Force very much wants to use it, a lot.

America now has three major rocket companies, SpaceX, ULA, and Blue Origin. It also has Rocket Lab, which has a smaller rocket but intends to introduce its own larger version in 2025.

The 2025 launch race:

8 SpaceX
2 China
1 Blue Origin

Nor is the launch action over. Tomorrow SpaceX will attempt the seventh orbital test launch of its Starship/Superheavy rocket, the one-hour launch window opening at 4 pm Central.

Live stream of first New Glenn launch

6:42 pm

I have once again embedded below Blue Origin’s live stream of its attempt tonight to complete the maiden launch of its orbital New Glenn rocket.

The launch window of three hours opens at 1 am (Eastern). It would be nice if Blue Origin’s announcers showed some improvement in their delivery tonight but I have doubts. Expect as always lots of “This is so exciting!” and “Aren’t you excited?” and “Isn’t this the most exciting evening yet!” Blah.

As I’ve said, their audience doesn’t want emotion, it wants detailed information provided coolly. If they do that, they will do more to sell their rocket than anything.

UPDATE: It appears Blue Origin management might have seen the blistering criticisms of its launch coverage yesterday. Instead of starting the live stream an hour before, they are now going to start it at T-20 minutes, but have also placed the count on hold at T-20:50. This avoids blather, especially if mission control is not going to provide the announcers any concrete information, as they did yesterday.

The change from simply recycling the count to an actual hold is also a positive change. Simply recycling the count (by adding 20-30 minutes periodically while they work out issues) puts pressure on the launch team unnecessarily. Better to work under a hold.

The count now has been recycled to 30 minutes and is rolling. We shall see if the podcast goes live at 20 minutes.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 31, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled simply as a “terrain sample” by the camera team, it was likely taken not as part of any specific research project but to fill a gap in the camera’s schedule in order to maintain its proper operating temperature.

In this case the camera team picked a spot in the northern lowland plains at 39 degrees north latitude. What they got was another great piece of evidence of the existence of a lot of near surface ice on Mars, so much so at this location that the craters have become distorted and blobby. The ice in the ground is unstable enough that nothing here can really hold its shape from season to season and from decade to decade.

As I have noted repeatedly in the past six years, MRO data is proving that Mars is not a dry desert like the Sahara, but an icy desert like Antarctica. Except for the planet’s dry tropics below 30 degrees latitude, Mars appears to have a lot of frozen water available relatively near the surface.
