SpaceX’s fourth manned Dragon capsule named “Freedom”

9:38 am

Capitalism in space: The astronauts who will fly to ISS on April 19th on the SpaceX’s fourth manned Dragon capsule announced yesterday that they named it “Freedom,” both to honor that fundamental human right that is also fundamental to American history as well as to honor the memory of the first American spacecraft, Freedom 7, which launched Alan Shepard on his short suborbital flight in 1961.

Once launched, SpaceX will have a fleet of four manned capsules, Endeavour, Resilience, Endurance, and Freedom.

Endeavour has carried humans aloft twice for NASA, and is scheduled to fly a record third time on April 3rd when it carries four commercial passengers to ISS for the company Axiom.

Resilience has also flown twice, once for NASA and once for SpaceX itself, launching a crew of commercial passengers in the fall of 2021.

Endurance has flown once, for NASA.

With the addition of Freedom, SpaceX will have a fleet of four manned spacecraft, matching the size of NASA’s now gone shuttle fleet. Whether the company will need to build more will depend on demand and on the number of missions it thinks these reusable capsules can complete safely.

NASA solicits proposals for second commercial manned lunar lander

9:25 am

Having received a budget boost from Congress for its manned lunar lander Artemis program, NASA yesterday announced that it is soliciting proposals from the private sector for a second lunar lander, so that the agency will not be reliant only on SpaceX’s Starship.

To bring a second entrant to market for the development of a lunar lander in parallel with SpaceX, NASA will issue a draft solicitation in the coming weeks. This upcoming activity will lay out requirements for a future development and demonstration lunar landing capability to take astronauts between orbit and the surface of the Moon. This effort is meant to maximize NASA’s support for competition and provides redundancy in services to help ensure NASA’s ability to transport astronauts to the lunar surface.

As part of this revised program, NASA also is negotiating a revision to its contract with SpaceX. It appears that this change will have SpaceX fly an additional manned mission with Starship, after which NASA would open up competition to everyone on future flights. The press release however is not entirely clear on this point.

This new competition will of course be a boon to the losers in the first manned lunar lander competition, Blue Origin and Dynetics. Both will certainly submit bids, as will others.

Blue Origin delays 1st New Glenn launch again

9:10 am

Capitalism in space: At a conference earlier this week Blue Origin officials confirmed that the first test flight of its orbital New Glenn rocket will not occur in ’22, but will be delayed again, into ’23.

New Glenn was originally supposed to launch in 2020, and has been delayed repeatedly since then, first because of new requirements imposed by the military and then because of delays in getting Blue Origin’s BE-4 rocket engine operational.

Though ULA is still aiming to launch its Vulcan rocket using the BE-4 in 2022, expect it to eventually recognize reality and delay also to ’23. That rocket was also supposed to make its first launch in ’20, and has been delayed for the same reasons.

These delays have cost both companies dearly. For example, had each been operational as planned, they might have won some or all of the launch contracts that OneWeb lost from the Russians. Instead, that business went to SpaceX.

Ingenuity completes 22nd flight; Perseverance on a roll

11:37 am

Overview map
Click for interactive map.

According to a tweet from JPL on March 21, 2021, Ingenuity successfully completed its 22nd flight on Mars during the March 19-20th weekend, flying for 101 seconds at a height of about 30 feet.

The tweet provided no other information, other than another flight might occur as early as later this week.

However, the most recent map update from the rover/helicopter science teams, shown to the right and annotated to post here, tells us what happened. The white dotted line indicates Perseverance’s travels. The tan dotted line indicated the flight path and landing spots for Ingenuity. The dashed tan lines indicate the planned routes for both. The red dot marks Perseverance’s present location. The green dot marks Ingenuity’s location, after its 22nd flight.

The announced flight plan for Ingenuity’s 22nd flight is shown by the two blue dots, heading north and then making a sharp left before landing. Apparently, the helicopter either did not complete that plan, landing earlier for some reason, or the flight team had decided before takeoff to shorten the flight plan significantly.

What we do know is that the helicopter landed safely, from images downloaded on March 20th [sol 384] and from the JPL tweet. The next flight, targeting later this week, could attempt to complete the previous flight plan, or instead continue to break it up into small sections.

Meanwhile, Perseverance has been racing across the Martian surface, traveling almost as much in the past week as it had for the past year. (See the map from March 16th to compare.) Moreover, the Perseverance team shortened its planned route, cutting to the west of that large crater rather than skirting it to the east. The route taken was probably slightly rougher, but nothing the rover couldn’t handle, and it saved travel time. Apparently, the scientists running the rover are now very eager to finally get to the delta, the mission’s primary geological target.

ISS: Breaking up is hard to do

11:00 am

According to this detailed article by Eric Berger at Ars Technica, it will be be very difficult if not impossible for Russia to detach its half from ISS and go its own way.

The article outlines both the technical and legal reasons, and concludes as follows:

In reality, during the coming years, we are more likely to see food riots in Moscow than we are to see a new Russian Space Station or a deep space scientific exploration mission. Some of this will be due to financial concerns, and some of it will come because of a loss of access to technology from the West.

Already, Russia’s main builder of tanks, Uralvagonzavod, appears to have stopped production due to a lack of components. Roscosmos’s big four companies—RKK Energia, RSC Progress, the Khrunichev Center, and NPO Energomash—will likely not be able to keep up production for long for the same reason as the tank factory.

While everything Berger notes is true, I think he underestimates the willingness of rogue nations, as Russia presently is, to break treaties. Also, the agreements Russia has signed expire in 2024, and Russia needs the next few years to launch more modules to have any chance of making its half workable. Whether it can do it is presently doubtful, but not impossible.

This partnership is ending, whether by choice or reality. Expect Russia’s participation in ISS to continually wind down over the next few years.

Startup rocket company begins delivering engines

9:55 am

Capitalism in space: The startup rocket company, Ursa Major, announced today that it has completed qualification tests of its new Hadley rocket engine and has begun delivering flight worthy engines to two different companies.

Startup Ursa Major announced Wednesday that it had completed qualification of its Hadley rocket engine for use by both a space launch vehicle and a hypersonic launch system. The Colorado-based company said it has already started delivering flight-ready Hadley engines to two customers, Phantom Space and Stratolaunch, and plans to produce a total of 30 engines this year.

The engine is relatively small compared to most rocket engines. Phantom will use seven in the first stage of its smallsat Daytona rocket, designed to launch cubesats into orbit. What Stratolaunch will use the engine for is unclear.

Blue Origin’s engine division manager leaves company; first BE-4 engines arriving in May

9:48 am

Capitalism in space: The head of Blue Origin’s rocket engine division has decided to leave the company, even as it was revealed that the first flight worthy BE-4 engines will not be delivered to ULA until May at the earliest.

According to company sources, the first two BE-4 flight engines are in final production at Blue Origin’s factory in Kent, Washington. The first of these engines is scheduled to be shipped to a test site in May for “acceptance testing” to ensure its flight readiness. A second should follow in reasonably short order. On this schedule, Blue Origin could conceivably deliver both flight engines to United Launch Alliance in June or July. Sources at Blue Origin and United Launch Alliance say development versions of the BE-4—which are nearly identical to the flight versions—have been performing well in tests.

Upon receiving the engines, United Launch Alliance plans to install two of the BE-4s on the Vulcan rocket for a debut launch as soon as possible. While at the Satellite 2022 conference in the District of Columbia, United Launch Alliance CEO Tory Bruno on Tuesday said he still anticipates that Vulcan’s debut launch will occur in 2022. However, a summertime delivery would be a very tight schedule for United Launch Alliance.

ULA was initially promised these engines more than three years ago. The delay not only put its Vulcan rocket three years behind schedule, it has delayed the development of Blue Origin’s own orbital rocket, New Glenn, by more than three years as well.

To supply the needed engines for both rockets Blue Origin will need to establish a production line that can churn them out at a much faster pace than indicated so far. Whether it can remains an unknown, with the exit now of the head of the company’s engine division making that unknown even more worrisome.

Firefly raises $75 million, targets May for next launch attempt

9:33 am

Capitalism in space: In announcing that the company has raised $75 million more in private investment capital, Firefly officials also said that it is now targeted May for its next launch attempt of its Alpha rocket.

The launch was partly delayed because of the federal government’s insistence that a Ukrainian businessman, who had saved the company when it went into bankruptcy, divest his ownership. That has now happened, so Firefly has gotten approval to launch.

Firefly CEO Tom Markusic told CNBC that the company “worked methodically and cooperatively with the government” to both complete the divestment, as well as to add “security protocols” at the company.

With the move complete, Markusic said the company now has “full access to our facilities to go back and launch.” Firefly will next transport its second Alpha rocket from its headquarters near Austin, Texas, to California, and aims to launch as soon as it can.

“We think it’ll take us about eight weeks from here to launch — so in May is our target,” Markusic told CNBC.

The company is also aiming to complete its second test launch two months after the first, assuming all goes well.

SpaceX switches to newer Starship and Superheavy for orbital test

9:25 am

Capitalism in space: According to Elon Musk, SpaceX has decided that the company will no longer use Starship prototype #20 and Superheavy prototype #4 for the rocket’s first orbital test flight.

Instead, the company will fly two more recently built and upgraded prototypes, rumored to be numbers #24 for Starship and #7 for Superheavy. The company has also decided to switch from the first generation Raptor engines to Raptor-2s.

All these changes likely explain Musk’s announcement that the first orbital launch will not happen sooner than May. The changes also further suggest that SpaceX has realized federal permission to launch from Boca Chica will be further delayed, and thus it might has well push forward in other ways as it waits for the right to launch.

I suspect that if the federal government hadn’t moved in to block operations, it would have flown prototypes 20 and 4 two months ago, just to get some data. Now such a flight seems pointless, as more advanced prototypes are now almost ready to fly.

This decision also reinforces my prediction that no orbital flights will occur out of Boca Chica before summer, and are more likely blocked through November. It also increases my expectation that the first orbital flight might not occur at all in Texas. The longer the Biden administration delays SpaceX’s operations there, the greater the chance the entire Starship/Superheavy launch program will shift to Florida.

Local state legislators introduce bill to disband Camden spaceport authority

9:14 am

Two Georgia state legislators yesterday introduced a bill to disband the Camden spaceport authority, following a county special election that rejected the spaceport by a vote of 72% to 28%.

Whether the bill becomes law or not will likely not make much difference to the spaceport. It is dead, and the law will merely decide whether it dies quickly, or slowly.

This quote by one of the legislators who introduced the bill, however, should be carved in stone in every statehouse and in the Capitol in Washington:

“It’s hard to ignore how the people vote.”

Too many lawmakers nationwide have forgotten this fact.

Starlink raises its prices

9:06 am

Capitalism in space: Starlink has now unveiled newer higher prices for getting its internet service, even for those who had previously put down a deposit for the service.

Originally, opting into Starlink required a $499 upfront purchase of a starter kit with all the necessary supplies, including a user terminal, or antenna, for connecting with SpaceX’s satellites. Customers would then pay a $99 monthly charge to keep the service running. Now, the new monthly price going forward will be $110. All new orders of the Starlink kit will now cost $599, and anyone who put down a deposit for the original $499 kit will have to pay $549 instead. The new monthly prices will come into effect at different times for different customers.

The price increase either indicates the lack of competition existing for those who want good internet service in the regions Starlink presently serves, or it suggests the cost of launching the system is higher than Starlink first anticipated. Either way, the higher cost gives an opportunity to others.

The unbelievably rough and wind-swept surface of Mars’ Greenheugh pediment

11:17 am

Gator-back terrain on Mars
Click for full image.

Since my last update on the travels of the Mars rover Curiosity on February 22, 2022, the rover has been been creeping ever so slowly westward across a plateau that scientists have dubbed the Greenheugh pediment.

Scientists have known for years that the surface of the pediment was going to be rough going. This panorama taken by Curiosity when it first climbed up to the pediment in March 2020 to take a peek before retreating revealed that roughness starkly.

In truth, since beginning its traverse of that pediment in February, the Curiosity team has found the ground not only as rough as expected, but beautiful in a strange sort of way, as illustrated by the March 20, 2022 photo to the right, reduced to post here. As Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center, noted yesterday in a Curiosity update that featured this image:
