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

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.

Bursting ice sheets on Mars

12:46 pm

Ice sheets on Mars
Click for original image.

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.

7th Starship/Superheavy test launch delayed one day

11:50 am

SpaceX has delayed its planned seventh test flight of its Starship/Superheavy rocket one day, from today to tomorrow, with the one-hour launch window now beginning at 4 pm (Central) on January 16, 2025.

It appears high winds and rain today were the main factor in the delay. Tomorrow will be better, with the weather continuing to improve over the next few days. We should not be surprised thus if the launch gets delayed one more time for weather.

Spadex’s unmanned docking faces possible two month delay

9:51 am

India’s Spadex mission, launched to test autonomous unmanned docking procedures necessary for many of that country’s future space plans, now faces a possible two month delay in orbit before the final docking can take place.

On January 11, 2025 the chase vehicle completed its closest proximity maneuver, getting within three meters of the target vehicle, after which it backed away as planned. ISRO engineers are presently analyzing the data before proceeding with the actual docking.

The problem is that this docking must occur by January 20, 2025. After that the lighting conditions will not allow another attempt until March.

It seems ISRO is not concerned about this situation, and would rather get things right, even if it means that delay.
