Webb’s coldest instrument reaches operating temperature

1:32 pm

The engineering team announced today that the mid-infrared instrument on the James Webb Space Telescope has now cooled to its operating temperature of -447 degrees Fahrenheit, less than 7 kelvin degrees above absolute zero.

On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its final operating temperature below 7 kelvins (minus 447 degrees Fahrenheit, or minus 266 degrees Celsius).

Along with Webb’s three other instruments, MIRI initially cooled off in the shade of Webb’s tennis-court-size sunshield, dropping to about 90 kelvins (minus 298 F, or minus 183 C). But dropping to less than 7 kelvins required an electrically powered cryocooler. Last week, the team passed a particularly challenging milestone called the “pinch point,” when the instrument goes from 15 kelvins (minus 433 F, or minus 258 C) to 6.4 kelvins (minus 448 F, or minus 267 C).

Before science operations can begin the instruments still need further calibration and testing. Expect the first infrared images sometime in the next month or so.

Space Perspectives unveils luxurious interior of Neptune high altitude balloon

9:41 am

Capitalism in space: Space Perspectives has now unveiled the high class stateroom interior that it plans to put inside its Neptune high altitude balloon that will take tourists to 30+ miles altitude.

Space Perspective just released artist’s illustrations of the interior of Spaceship Neptune, which will include 360-degree panoramic windows and even a restroom with a view. The announcement Tuesday (April 12) coincided with the anniversary of the first human spaceflight by cosmonaut Yuri Gagarin in 1961.

Based on the imagery, Spaceship Neptune’s cabin appears to come in at least a couple of configurations. One has reclining seats, for example, while another with couches can accommodate a “more intimate dinner for two or special event,” Space Perspective representatives said in a statement on Tuesday.

Space Perspective will provide food and beverage services, and the capsule features mood lighting that can be dimmed to see stars or the curvature of Earth outside. Also included in the capsule’s “Space Lounge” will be a telescope, interactive screens and decorations such as floor lamps and plants to “remind us of the interconnected nature of our planet,” the company added.

The company hopes to begin commercial flights by ’24, each of which will last about six hours. Tickets are priced at $125K each, with the company saying it already has 600 people on its waiting list.

MAVEN and Al-Amal scientists sign agreement to collaborate

1:20 pm

Scientists running the Mars orbiters MAVEN (from NASA) and Al-Amal (from the United Arab Emirates [UAE]) have signed an agreement to share data and — more importantly — coordinate their observations of the Martian atmosphere.

A new partnership that encourages the sharing of data between NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) project and the Emirates Mars Mission’s (EMM) Hope Probe (Al-Amal in Arabic) will enhance scientific returns from both spacecraft, which are currently orbiting Mars and collecting data on the Red Planet’s atmosphere. The arrangement is expected to add value to both MAVEN and EMM, as well as the scientific communities involved in analyzing the data the missions collect.

MAVEN went into orbit around Mars in 2014. Its mission is to investigate the upper atmosphere and ionosphere of Mars, offering an insight into how the planet’s climate has changed over time. “MAVEN and EMM are each exploring different aspects of the Martian atmosphere and upper-atmosphere system,” said Shannon Curry, MAVEN principal investigator from the University of California, Berkeley. “Combined, we will have a much better understanding of the coupling between the two, and the influence of the lower atmosphere on the escape to space of gas from the upper atmosphere.”

The EMM Hope Probe, which went into Mars orbit in 2021, is studying the relationship between the upper layer and lower regions of the Martian atmosphere, giving insight into the planet’s atmosphere at different times of the day and seasons.

What this agreement means is that the two science teams can more quickly match up the data from both orbiters, and figure out the relationships between both.

ULA orders 116 rocket engines from Aerojet Rocketdyne for its Vulcan upper stage

10:33 am

Capitalism in space: In order to meet its contract with Amazon to launch a lot of Kuiper satellites, ULA has now ordered 116 rocket engines from Aerojet Rocketdyne for the Centaur upper stage of its new and as-yet unlaunched Vulcan-Centaur rocket.

Aerojet said this was the company’s largest ever contract for the RL10 engine. The large purchase of rocket engines comes on the heels of Amazon’s announcement April 5 that it selected Arianespace, Blue Origin and ULA to launch up to 3,236 satellites for its Project Kuiper broadband constellation.

CEO Tory Bruno said ULA plans to fly Vulcan’s first mission late in 2022. Winning the Amazon deal would more than double the annual rate of Vulcan launches to as many as 25 per year, and ULA will ramp up production to meet the demand, Bruno said last week at the Space Symposium.

ULA’s engine choice for Vulcan’s upper stage dates back to 2018 when it selected a variant of the RL10, the same engine used to power the upper stages of ULA’s legacy rockets Atlas 5 and Delta 4 Heavy. Over the past 60 years, more than 450 RL10 engines have flown on various ULA heritage vehicles.

Meanwhile, ULA hopes to get its first BE-4 engines from Blue Origin, needed for the Vulcan first stage, this summer. Vulcan-Centaur cannot make its first launch until it gets some flightworthy BE-4 engines, and these are now three years behind schedule.

Russia backs off its threats to leave ISS partnership

10:19 am

In several short news posts on Russia’s state-run press today, the Putin government indicated that it has backed off from its threats to end the partnership at ISS quickly.

First, Roscosmos’s head, Dmitry Rogozin, announced that it will proceed with its barter deal with NASA and allow astronauts from NASA and others to fly on Soyuz while Russian astronauts fly on Dragon and eventually Starliner.

“Why give up something that is useful? Anna Kikina [Russian woman cosmonaut] flew to Houston (USA) to familiarize herself with the design of the modules of the ISS American segment and the Crew Dragon spacecraft whose crew she may join. On our part, we are not ruining anything and keep to preliminary accords, although we continue waiting for the government’s decision on the program of cross flights,” Rogozin explained.

Second, Rogozin made statements that suggested Russia will maintain its full partnership on ISS through ’24, and maybe beyond.

Now Russia has to set up its mind about the year until which it cooperates on the ISS project, Rogozin said. “Yes, the Americans want it [cooperation] to last until 2030. The previous talks said that it would be until 2028. But let me repeat again that we have to decide on the main thing: to continue cooperation on the ISS or switch to the ROSS [Russian Orbital Service Station]. Subsequently, we will decide on what to do with our two new modules on the ISS that we docked last year,” Rogozin said.

In other words, Russia ain’t going no where. It might decide eventually to launch a new core module for their own station, and then transfer the newer modules on ISS to it, but none of this will happen until a final date for ISS’s deorbit is established.

Based on Rogozin’s earlier bombastic threats, I had expected Russia to take a harder position. It appears cooler heads in Roscosmos convinced Rogozin and Putin that in terms of cost and safety, a quick exit made no sense.

This decision to back off was also probably influenced by Russia’s losses in the Ukraine. It is no longer in a strong negotiating position in anything, has lost almost all its economic partnerships with the west, and thus does not wish to lose the one partnership that remains, on ISS.

Curiosity retreating from Greenheugh Pediment

10:05 am

Overview map
Click for interactive map.

Because of the incredible roughness of the ground on the Greenheugh Pediment, the science team for the rover Curiosity has decided to make a major change in their route. Rather than continue their traverse across this terrain, as planned for years, they have decided to back off in order to protect Curiosity’s dinged wheels, and find a more friendly route up Mount Sharp.

“It was obvious from Curiosity’s photos that this would not be good for our wheels,” said Curiosity Project Manager Megan Lin of NASA’s Jet Propulsion Laboratory in Southern California, which leads the mission. “It would be slow going, and we wouldn’t have been able to implement rover-driving best practices.”

The gator-back rocks aren’t impassable – they just wouldn’t have been worth crossing, considering how difficult the path would be and how much they would age the rover’s wheels.

So the mission is mapping out a new course for the rover as it continues to explore Mount Sharp, a 3.4-mile-tall (5.5-kilometer-tall) mountain that Curiosity has been ascending since 2014. As it climbs, Curiosity is able to study different sedimentary layers that were shaped by water billions of years ago. These layers help scientists understand whether microscopic life could have survived in the ancient Martian environment.

The plan is to retrace the rover’s path back through Gordon Notch and then head uphill though another gap that will take it directly onto the next sedimentary layer, dubbed the sulfate unit. On the overview map above, the red dotted line shows the long-planned route. The yellow lines indicate the area seen in the panorama I posted on April 6th, when Curiosity was at its farthest into the pediment. The blue dot marks Curiosity’s position two days ago. You can see that it has retreated backwards.

This change means the scientists will likely not get a close look at Gediz Vallis Ridge. However, it also means the rover will likely reach Gediz Vallis much sooner that previously planned.

Neptune’s cooling when it should be warming

9:45 am

Neptune since 2006

The uncertainty of science: Observations of Neptune during the past seventeen years using the Very Large Telescope have shown the planet mostly cooling during this time period, even though Neptune was moving into its summer season.

Astronomers looked at nearly 100 thermal-infrared images of Neptune, captured over a 17-year period, to piece together overall trends in the planet’s temperature in greater detail than ever before. These data showed that, despite the onset of southern summer, most of the planet had gradually cooled over the last two decades. The globally averaged temperature of Neptune dropped by 8 °C between 2003 and 2018.

The astronomers were then surprised to discover a dramatic warming of Neptune’s south pole during the last two years of their observations, when temperatures rapidly rose 11 °C between 2018 and 2020. Although Neptune’s warm polar vortex has been known for many years, such rapid polar warming has never been previously observed on the planet. “Our data cover less than half of a Neptune season, so no one was expecting to see large and rapid changes,” says co-author Glenn Orton, senior research scientist at Caltech’s Jet Propulsion Laboratory (JPL) in the US.

The sequence of photos above show that change over time. Lower latitudes generally get darker, or cooler, while the south pole suddenly brightens, getting hotter, in 2020.

The scientists have no idea why this has happened, though they have theories, ranging from simple random weather patterns to the influence of the Sun’s sunspot cycle.

Rocket Lab breaks ground on Neutron rocket factory

9:22 am

Capitalism in space: Rocket Lab yesterday broke ground on the construction of its larger proposed Neutron rocket factory at Wallops Island, Virginia, right next door to where the company plans to launch it.

The 250,000 square foot Neutron Production Complex is being constructed on a 28-acre site adjacent to the NASA Wallops Flight Facility and Mid-Atlantic Regional Spaceport on Virginia’s Eastern Shore. The complex will support Neutron production, assembly, and integration, and is expected to bring up to 250 highly-skilled roles to the region. Construction will also soon begin on a launch pad for Neutron at the southern end of Wallops Island, near Rocket Lab’s existing launch pad for the Electron rocket.

Neutron will largely reusable, its first stage returning to Earth for reuse, and carrying with it the skin of the second stage. The design combines this skin with the fairings that protect the payload and second stage engine, so that only the second stage engine is lost in orbit.

ISRO hires company to build future PSLV rockets

9:13 am

Capitalism in space: For the first time, India’s space agency ISRO is about to hire a private company to build five PSLV rockets, rather than supervise the construction in-house.

Hindustan Aeronautics Limited (HAL) and L&T consortium has emerged as the lowest bidder to make 5 Polar Space Launch Vehicles (PSLVs) for ISRO. “The company is the lead partner with L&T sharing the work. Other vendors too will be involved with the consortium in the manufacturing of the launch vehicles (LVs). However, the contract is yet to be formalised/ awarded,” HAL said in a statement.

If all goes as planned, the first rockets will be delivered late in ’24.

This contract changes less than it seems, though it is a step in the right direction. ISRO has for years hired private subcontractors to build its rockets and components. What is different now is that it appears that HAL is now the lead contractor, not ISRO. HAL however does not appear to own the rockets it builds, and thus will not be able to build more to sell launches to others. Until this happens, India’s space industry will remain wholly government run.

Perseverance arrives at Three Forks at the base of Jezero Crater’s delta

12:01 pm

Panorama of delta in Jezero Crater
Original images found here, here, here, and here. Click for full resolution.

Overview map
Click for interactive map.

Cool image time! The panorama above was created from four navigation camera images taken by the Mars rover Perseverance on April 10th. Because the lens on Perseverance’s navigation cameras produce slightly curved images which are taken in pairs, the panorama is made of two parts, each a pair perfectly matched images looking from a different angle. I have overlapped the pairs but as you can see, the match at the center is imperfect. While this does not produce a single smooth image, the two paired panoramas show the foot of the entire delta that had flowed into Jezero crater in the past and is the prime geological target of the rover. What is it made of? What caused it to flow into the crater? When did it do it? How was Mars different when it did so? Was the crater wet? Was the delta mud when it flowed, or was it sediment under water, pushed out by that flowing water?

The location map to the right is taken from the “Where is Perseverance?” webpage but annotated to show the planned routes of both Perseverance and Ingenuity, as shown by the tan dashed lines. The red dot marks Perseverance present location, the green dot Ingenuty’s. The yellow lines the approximate area covered by the panorama.

What next? Expect Perseverance to move as close to the base of the delta’s cliff as possible and spend at least several months studying it. Ingenuity meanwhile will be flown to the west to scout the various hollows that are potential routes for Perseverance to climb up onto the delta.

Astroscale demo to test space junk removal struggles with failed thrusters

9:35 am

Capitalism in space: Astroscale demo mission, ELSA-d, has been unable to complete a docking with its target vehicle as planned because four of the eight thrusters on the capture “servicer” vehicle have failed.

Engineers had separated the servicer from the target in January so that it could perform a rendezvous and then docking, from a distance, but that test was halted when engineers detected what the company only labeled as “anomalous spacecraft conditions.” This new announcement reveals what that problem was.

With safety always paramount, the Astroscale team has used a complex mix of burns with the remaining thrusters, aerodynamic drag and the natural perturbations of Earth’s gravity to bring the servicer safely back to a distance where operations can continue.

This revised plan began on February 18th, and has now apparently been mostly completed. However, rather than dock, the company has decided to only approach as close to 160 meters (525 feet) to test some sensors, and then retreat. Whether they will then attempt a recapture remains undecided.

Astroscale’s goal is to convince satellite companies to install its magnetic capture device on their satellites. Astroscale’s servicer could then use it to dock with a defunct satellite and deorbit it or maybe fix it. This demo flight was to prove the rendezvous and capture device worked.

NASA will not load fuels in SLS upper stage in next dress rehearsal countdown attempt

12:29 am

In the next attempt to complete the first “wet dress rehearsal” of NASA’s SLS rocket tomorrow, April 11th, the dress rehearsal will not be as wet as originally planned.

NASA said April 7 that engineers found a problem maintain helium purge pressure in the ICPS [SLS’s upper stage] after changing out a regulator in the mobile launch platform. At that time, the agency said it was able to restore normal pressure but was still studying the source of the problem, now linked to the faulty valve in the ICPS itself.

Because that issue, NASA now plans to limit the amount of liquid oxygen and liquid hydrogen propellant loaded into the ICPS during the WDR. NASA said the countdown rehearsal will be modified with “minimal propellant operations” on the ICPS, but didn’t elaborate on how much propellant would be transferred into the upper stage.

As usual, NASA officials are now making believe that they will achieve all their goals for the dress rehearsal if they complete it without completely fueling the upper stage. This is intellectually dishonest. This dress rehearsal was intended to test all aspects of the rocket’s launch countdown, including the fueling of all its stages. If they complete it without successfully fueling the upper stage, they will not achieve all their goals. Period.

The plan right now is to attempt this revised launch rehearsal tomorrow, then return the rocket to the vehicle assembly building where engineers will replace the faulty valve. At that point it is unclear what the agency will do next.

Though this incomplete test will have taught them a lot, if they do not redo the dress rehearsal with full loading of all stages but instead proceed to a launch attempt in the present target window from June 6 to June 16, they will be doing so with a greater risk. Of course, if the new valve works during that launch attempt, then all should be well. In fact, this risk appears quite reasonable.

Nonetheless, the fundamental problem remains: NASA is under pressure to launch, and held off this kind of testing until very late in the program. Finding these problems now puts serious limits on the ability of the agency to fix them. This in turn puts serious limits on the reliability of SLS.

Splonk went the crater!

Splonk went the crater!
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on February 18, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “degraded crater in Utopia Planitia.”

There is a lot of intriguing geology in this one image. First of course is the crater itself. We have to ask, is it from an impact or from some volcanic process? The location, at 44 degrees north latitude, argues that some form of ice or mud process was involved. Maybe we are looking at a frozen eruption from an underground ice layer. If this was instead caused by an impact, the crater’s ringlike structure could have been created by the ripples of melted ice and mud emanating away but then quickly refreezing.

Surrounding the crater are many small fissures, the largest ones all oriented in a north-south direction. If there is an ice layer near the surface, these cracks might be caused by that ice sublimating away. Why the largest cracks orient in the same direction however is a mystery.

The color variations suggest [pdf] dust (red-orange) as well as a variety of minerals (green). Since no blue appears visible in this version of the photo, if this crater was shaped by melting or erupting ice, that ice is well covered by that layer of dust and debris.

The location map below as always provides context.

French company raises €2 million to launch commercial solar sail

9:23 am

Capitalism in space: The French startup Gama has successfully raised €2 million to build and launch its first test solar sail, with the goal of eventually selling those sails for other interplanetary missions.

Gama plans to deploy a 73.3-sq-metre solar sail in a 550km-altitude orbit in October. It will be launched as an additional payload on a SpaceX rocket.

There have been a number of previous solar sail deployment tests by Nasa and the American space advocacy group the Planetary Society. However, the Japan Aerospace Exploration Agency had been the only organisation to successfully sail on sunlight. In 2010 it used a solar sail to power the experimental Ikaros (Interplanetary Kite-craft Accelerated by Radiation of the Sun) spacecraft to Venus.

If successful the company will follow with two more test missions in ’24 and ’25, first testing at higher orbit and testing in interplanetary space.

Starlink delivers 5,000 terminals to Ukraine; loses license in France

9:03 am

Capitalism in space: Starlink today continued its aggressive support for the Ukraine in its war with Russia by delivering another 5,000 terminals to that beleaguered country.

Space reporter Joey Roulette tweeted Wednesday that the majority of the terminals — 3,667, to be exact — as well as the associated internet service were donated directly by SpaceX at a cost of “roughly $10 million,” with USAID purchasing the remaining 1,333 terminals. These numbers apparently came from an earlier version of the USAID release; the updated release doesn’t give dollar figures and refers only to 5,000 Starlink terminals donated by a public-private partnership.

Roulette also suggested in another tweet that France and Poland had made contributions to the Starlink shipments to Ukraine, citing an earlier conversation with SpaceX president and chief operating officer Gwynne Shotwell. The USAID announcement only refers to the American partnership, however.

In a second story today, however, Starlink lost its ability to provide service in France, when a court ruled its license had been issued improperly.

France’s Conseil d’État ruled April 5 that French telecoms regulator ARCEP should have launched a public consultation before authorizing Starlink in February 2021.

“In law, they should normally cease [providing services] immediately, pending ARCEP’s public consultation” following the court’s decision, a Conseil d’État spokesperson told SpaceNews.

The court case was apparently instigated by two French environmental groups, who are demanding more regulations against the large satellite constellations.

Relativity still targeting a ’22 first launch

8:56 am

Capitalism in space: The startup rocket company Relativity is still targeting this year for the first test launch of its 3D-printed Terran-1 rocket, according to its CEO Tim Ellis.

The company has raised more than $1 billion in private investment capital.

If successful, Relativity will join Rocket Lab, Virgin Orbit, and Astra as a small satellite launch provider, all capable of launching military and commercial smallsats quickly. The competition will guarantee that their prices will be low as well.

SpaceX successfully launches Axiom’s first commercial flight to ISS

8:19 am

Capitalism in space: SpaceX today successfully launched the first commercial mission to ISS by the private company Axiom, carrying three passengers and one Axiom astronaut as commander.

The replay of the live stream of the launch is embedded below.

The first stage, which landed successfully on the drone ship in the Atlantic, completed its fifth flight. The capsule Endeavour was making its third flight. This is also the second private manned mission launched by SpaceX.

Docking with ISS is scheduled for early tomorrow morning.

All in all, it was a perfect launch, on time and as planned. This has become so routine for SpaceX that we tend to take it for granted. We shouldn’t. Launching people into space remains one of the hardest things humans do, and will likely always be so.

The leaders in the 2022 launch race:

13 SpaceX
9 China

2 ULA
2 Rocket Lab

The U.S. now leads China 20 to 9 in the national rankings.

Commercial imaging satellites prove their military worth in the Ukraine War

9:36 am

Capitalism in space: Because of the ability of private commercial satellites to obtain high resolution reconnaissance and radar images of the ground quickly, U.S. intelligence agencies decided right before the Russian invasion of the Ukraine to not only use those satellites, but to funnel that data both to the public and to the Ukraine.

“We partner with over 100 companies, we’re currently using imagery from at least 200 commercial satellites and we have about 20 or so different analytic services in our pipeline,” David Gauthier, director of commercial and business operations at the National Geospatial-Intelligence Agency (NGA), said during a panel discussion at the 37th Space Symposium. “Because of all that, when Russia prepared to invade, we and the NRO [National Reconnaissance Office] increased and accelerated several efforts that were underway commercially,” said Gauthier.

The daily flow of intelligence that previously was only available from government sources and seldom released to the public is no accident, said Gauthier. “This moment has really been set up by a lot of hard work by many companies and many in the government to prepare ourselves to take better advantage of commercial capabilities.”

Leading up to the conflict, he said, “we more than doubled the commercial electro-optical imagery that was bought over Ukraine.” Imagery from companies like Maxar, BlackSky and Planet “was able to flow directly to those who need it, EUCOM [U.S. European Command], NATO and directly to Ukrainians,” Gauthier said.

The military’s increased reliance on reconnaissance imagery from these private commercial satellite constellations during this war is likely to accelerate the military’s switch from building its own big and expensive government satellites — which also launch rarely and provide little redundancy — to using the private sector for its needs.

In other words, the success of the private sector in this area during this war has once again proved the validity of the recommendations in my 2017 policy paper, Capitalism in Space [pdf].

The government should stop being a builder and instead become merely a customer. Let competing private companies do the work. Not only will the government get what it needs faster and for far less, the competition will fuel innovation and prosperity for the American people.

Update on SpaceX’s Starship/Superheavy operations at Boca Chica

9:22 am

Link here. Though the permitting process for launching Starship from Boca Chica is stalled or maybe even blocked, SpaceX is continuing to use this waiting time to upgrade and improve the design of both Starship and its giant booster, Superheavy, abandoning earlier prototypes for newer versions incorporating those upgrades.

[Superheavy] Booster 4 and [Star]Ship 20, having served as articles to test the ground systems and verify the major design outlines of booster and ship, have now been phased out, with Elon Musk confirming on Twitter that these wouldn’t perform the long-awaited orbital velocity test flight.

Instead, it is now expected that Booster 7 and Ship 24 will be the duo performing this duty. For that same reason, SpaceX cleared the way for Booster 7 by removing Booster 4 from the OLM on March 24.

The company has been doing tank tests and stack tests of these new prototypes at a fast pace, even as it is assembling even newer prototypes.

ISRO once again delays first launch of its new SSLV rocket

9:12 am

India’s space agency ISRO today announced that it is once again delaying the first launch of its new Small Satellite Launch Vehicle (SSLV) rocket.

This rocket, designed to launch cubesats and compete with private companies like Rocket Lab, Virgin Orbit, and Astra, was first going to launch in the summer of 2019. That launch was delayed until 2020, only to be blocked entirely for two more years because of India’s panic over the Wuhan flu.

Last month ISRO announced the successful completion of static fire tests of the rocket’s solid rocket first stage, suggesting a spring launch in ’22 would occur. That has now been delayed again, now targeting early summer.

The delays have cost India a great deal in market share. Had SSLV launched in 2020, it would have been well positioned to garner business now captured by Rocket Lab, Virgin Orbit, and Astra, the latter two of which were not yet operational at that time. Now India trails all these companies, with other American companies (Firefly, Relativity, ABL) on the horizon as well.

Spinlaunch wins suborbital launch contract from NASA

9:00 am

Spinlaunch prototype suborbital launcher

Capitalism in space: Spinlaunch has won a launch contract from NASA to use its rocket-tossing spin launcher, shown in the photo to the right, to place a test payload on a suborbital flight later this year.

Unlike a vertical rocket first stage, the launcher spins its upper stage to a high acceleration and flings it upward. While the G-forces are too brutal for any delicate equipment or biology, this technique could be a very cheap way to toss bulk payloads like water and oxygen into space.

Spinlaunch has already done one test flight in November ’21, and hopes to do its first orbital test flight by ’25.

Breaking: Army Corp of Engineers suspends SpaceX’s Boca Chica permit process

8:50 am

We’re here to help you! According to this very short Bloomberg news report today, the Army Corp of Engineers has entirely suspended SpaceX’s Boca Chica permit process for expanding the facility.

The reason given is that SpaceX “failed to provide requested information.”

Though not yet confirmed, this permit appears to be separate from the environmental reassessment process being led by the FAA to approve Starship launches from Boca Chica. Instead, this appears to have an application to add an additional launchpad and other facilities to the site.

Assuming this distinction is true, then launches from Boca Chica of Starship might still be approved. The action however once again indicates the growing hostility to SpaceX within the federal bureaucracy, apparently aided and abetted by the Biden administration.

Curiosity’s upcoming rough terrain

Overview map
Click for interactive map.

Cool image time! The panorama above, created by me from four photos taken by Curiosity’s right navigation camera on April 5, 2022, reveal much about the alien world of Mars that the rover is exploring. The red dotted line indicates approximately the rover’s upcoming route.

First there is the rough surface of the Greenheugh Pediment, the sloping plateau that Curiosity is presently traversing. Called “gater-back terrain” by the science team, this broken surface apparently is sandstone that was originally a dune field that in the past was periodically washed by water runoff and later hardened into this structurally weak rock.

Second, I have orientated the images so that the rim of Gale Crater, approximately 25 miles away, is horizontal. By doing so, we can see the upward slope of the Greenheugh Pediment. Curiosity is on a tilted surface, and while it will be traversing along a contour line as it heads west towards Gediz Vallis Ridge about 1,000 feet away, when it turns left and heads uphill, the climb will be steady and steep, as it has now been for the past year since the rover entered the mountains at the foot of Mount Sharp.

Taken together, these details indicate why Curiosity has moved very slowly in recent weeks, as shown by the white dots in the overview map to the right. The blue dot marks Curiosity’s present location, with the yellow lines indicate the approximate view in the panorama above.

Traversing the pediment carries real risk to the rover. Though its somewhat dinged wheels have held up well during this last year of traveling in these rough mountains, at any point the severe roughness here could damage one or more wheels significantly, even putting one or more out of commission. The rover team is traveling carefully to avoid this, but these factors illustrate a possible end for the rover, though hopefully still years away.

Inspector General: NASA’s lunar rover VIPER mission on schedule, with some cost increases

11:19 am

VIPER's planned route on the Moon

According to a report [pdf] issued today by NASA’s inspector general, the agency’s VIPER lunar rover mission is generally on schedule for its ’23 launch, though it has experienced some cost increases and still carries some scheduling risks, mostly related to the development of Astrobotic’s commercial Griffin lunar lander, and its precursor Peregrine mission that ULA hopes to launch on its first Vulcan rocket test.

Although Astrobotic personnel explained that Griffin’s development schedule is largely independent of its Peregrine mission, the Peregrine Lander—planned to launch in 2022—has multiple systems and subsystems that will also be used on Griffin. Therefore, any technical problems with these systems may adversely affect development of the Griffin Lander because Astrobotic would only have about a year, depending on the Peregrine launch date and start of lunar operations, to resolve the issues prior to NASA delivering VIPER for integration and launch. Furthermore, any failures during the Peregrine mission may lead to Griffin delays as NASA and Astrobotic investigate the failures and develop corrective actions.

In addition, VIPER long-lead acquisitions—such as the rover solar power array and avionics unit—have been affected by aerospace industry supply chain delays caused by COVID-19 as have delivery of computer boards and motor parts. Both of these issues have impacted design verification testing needed for the mission’s Critical Design Review, while COVID-19 also delayed some component development schedules.

Peregrine’s launch has been delayed by a year because Vulcan has been delayed because of Blue Origin’s problems with the BE-4 rocket engine. Though ULA hopes the Vulcan/Peregrine launch can occur late this year, that date remains very much in doubt. Further launch delays would thus threaten the launch of Griffin and VIPER.

As for the cost increases, the IG found that NASA had been forced to increase the budget for VIPER by 18.1%, a relatively minor increase compared to many of NASA’s other big projects. The IG noted however that further cost overruns are very possible, especially if the Peregrine mission experiences problems.

The photo above shows the rover’s presently planned route in the relatively flat area about 85 miles from the Moon’s south pole and near the western edge of Nobile Crater (pronounced No-BEEL-e).

Europe to put instrument on Japanese rover being launched and landed on the Moon by India

9:49 am

The new colonial movement: The European Space Agency (ESA) has signed an agreement with Japan’s space agency JAXA to put a science instrument on a Japanese rover that will be launched by India to the Moon and landed there on an Indian lander.

Under the deal, ESA would provide instruments for the Japanese rover, which would be used in the exploration of the Moon’s south pole under the mission targeted for 2024. … The lunar endeavour between the Indian Space Research Organisation (ISRO) and JAXA is called the Lunar Polar Exploration Mission (LUPEX) which aims to launch an Indian lander and a Japanese rover to the Moon.

In the next three years a lot of landers and rovers are planning to land on the Moon, most built by private American companies flying NASA and private payloads, but also joined by probes being sent by Russia, China, and now this Japanese-Indian-European mission. Even if only half succeed, the exploration of the lunar surface will still be quite busy.

Ukrainian rocket development for Nova Scotia spaceport unhindered by war

9:40 am

Capitalism in space: The development of a Ukrainian rocket dubbed Cyclone 4M for of any satellite customers who choose to launch from a planned Nova Scotia spaceport has not been delayed by the Ukraine war.

“Everything is stable with respect to our team in Ukraine,” said Steve Matier, president of Maritime Launch Services. “The facility there is fine, the staff is fine and at work. . . . We’re continuing to finance their development of the launch vehicle.”

The Cyclone 4M rocket Maritime Launch Services plans to use is designed and built by Ukrainian state corporations Yuzhnoye and Yuzhmash in Dnipro. Known as Space City, Dnipro is located in central Ukraine. The city of about a million people was shelled in mid-March by Russian forces and the airport runways and terminal were hit by missile strikes, according to Ukrainian government statements.

This story illustrates the strong possibility that the recent success the Ukraine has had on the battlefield has served to prevented any serious long term damage to its aerospace industry and its partners in the west. Those partnerships if anything look stronger, with the work in the Ukraine apparently able to continue as planned, with only slight delays.

Commercial Orbital Reef space station passes NASA’s design review

Proposed Orbital Reef space station

Capitalism in space: A proposed commercial space station dubbed Orbital Reef and being built by a partnership led by Sierra Space and Blue Origin has passed its NASA’s design review, allowing for construction to now begin.

The review, conducted as part of a $130 million development contract from NASA, found no issues with the station’s design.

This commercial partnership also includes Boeing, Redwire, Mitsubishi, Genesis Engineering, and Arizona State University, and plans its launch before 2030 when ISS will be retired. This quote from the article I think is important:

“We’re going as fast as we can,” Steve Lindsey, chief strategy officer at Sierra Space, said during a panel at the Goddard Memorial Symposium March 25. “We don’t want to have a gap like we did with crew back in the last decade.”

Three other private space stations are also under construction or being planned, all hoping to be operational prior to ’30. If even two of these launch, the 2030s will be very exciting indeed.

Rocket Lab to attempt 1st stage recovery by helicopter on next launch

9:11 am

Capitalism in space: Rocket Lab will attempt during its next launch later this month to become the second commercial rocket company, after SpaceX, to successfully recover a first stage for reuse.

The company will use a customized Sikorsky S-92 helicopter to rendezvous with the stage as it descends slowly using parachutes and capture it. The helicopter will then fly it back to land and safely deposit it on the ground.

This launch is now scheduled for April 19th, at the earliest.

NASA postpones next SLS dress rehearsal countdown attempt to next week

11:06 pm

NASA officials today said that they have postponed their next attempt to complete the first dress rehearsal countdown of the SLS unitl next week, thus allowing the private commercial manned Axiom launch to ISS to proceed on April 8th.

The rocket will remain at the launch site as the engineering teams assess the issues that caused two scrubs and several launch count down holds.
