Launch of Intuitive Machine’s first lunar lander delayed

9:15 am

Capitalism in space: The first mission of Intuitive Machine’s lunar lander has now been delayed from late this year to early next year.

Intuitive Machines spokesman Josh Marshall said April 26 that the slip was caused by its launch provider. “SpaceX informed Intuitive Machines that due to unique mission requirements the earliest available flight opportunity is in the first quarter of 2022,” he told SpaceNews.

Marshall referred questions about the “unique mission requirements” that caused the delay to SpaceX. That company did not respond to questions from SpaceNews on the topic.

Though it is entirely possible that SpaceX needed to delay the launch, we should be skeptical of this reason. More likely Intuitive has had issues that caused a delay, and is using SpaceX as a cover.

There is a race to become the first privately-built commercial lunar lander. Astrobotics Peregrine lander is still scheduled to launch by the end of the year. We shall see.

Ingenuity’s fourth flight today

9:05 am

The fourth flight of the Mars helicopter Ingenuity has just occurred, with data arriving momentarily.

The fourth Ingenuity flight from Wright Brothers Field, the name for the Martian airfield on which the flight took place, is scheduled to take off Thursday, April 29, at 10:12 a.m. EDT (7:12 a.m. PDT, 12:30 p.m. local Mars time), with the first data expected back at NASA’s Jet Propulsion Laboratory in Southern California at 1:21 p.m. EDT (10:21 a.m. PDT).

…Flight Four sets out to demonstrate the potential value of that aerial perspective. The flight test will begin with Ingenuity climbing to an altitude of 16 feet (5 meters) and then heading south, flying over rocks, sand ripples, and small impact craters for 276 feet (84 meters). As it flies, the rotorcraft will use its downward-looking navigation camera to collect images of the surface every 4 feet (1.2 meters) from that point until it travels a total of 436 feet (133 meters) downrange. Then, Ingenuity will go into a hover and take images with its color camera before heading back to Wright Brothers Field.

Stay tuned for new images. NASA will also hold a press conference tomorrow to outline the results and the rest of Ingenuity’s test program.

Arianespace’s Vega rocket launches six satellites

8:52 am

Arianespace yesterday successfully completed its first Vega rocket lift-off since a launch failure last year, placing six satellites in orbit.

This was Arianespace’s first launch in 2021. Though the year is still early, the timing of this launch, late April, puts them well behind the pace they have set for most of the 21st century.

The leader board for the 2021 launch race remains unchanged:

12 SpaceX
10 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 10 in the national rankings.

SpaceX launches 60 more Starlink satellites; China launches Tianhe station module

10:16 pm

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.

China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.

The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

The leaders in the 2021 launch race:

12 SpaceX
10 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 10 in the national rankings.

Twisted taffy in the basement of Mars

2:53 pm

Taffy on Mars
Click for full image.

Cool image time! The photo to the right, taken on March 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows us an example of one of Mars’ strangest and most puzzling geological features, dubbed banded or “taffy-pull” terrain by scientists.

Taffy-pull terrain has so far only been found within Hellas Basin, Mars’ deepest impact basin and what I like to call the basement of Mars. Because of the lower crater count in this terrain scientists consider it relatively young, no more than 3 billion years old, according to this 2014 paper, which also notes

The apparent sensitivity to local topography and preference for concentrating in localized depressions is compatible with deformation as a viscous fluid.

At the moment what that viscous fluid was remains a matter of debate. Many theories propose that ice and water acting in conjunction with salt caused their formation, similar to salt domes seen on Earth. Other propose that the terrain formed from some kind of volcanic or impact melt process.

Almost all of the taffy terrain on Mars has been found in the deepest parts of Hellas Basin in a curved trough along its western interior, as shown by the light blue areas in the overview map below.

Today’s blacklisted American: Student is persecuted by university for asking a question

12:16 pm

Cancelled Bill of Rights
No longer exists at the University of Virginia

They’re coming for you next: Because medical student Kieran Bhattacharya dared to question the scientific validity of the term “microaggressions” during a panel discussion, the University of Virginia’s School of Medicine began an investigation that accused Bhattacharya of being a threat to others and banned him from the campus.

Here was what the student said.

“Thank you for your presentation,” said Bhattacharya, according to an audio recording of the event. “I had a few questions, just to clarify your definition of microaggressions. Is it a requirement, to be a victim of microaggression, that you are a member of a marginalized group?”

Adams replied that it wasn’t a requirement.

Bhattacharya suggested that this was contradictory, since a slide in her presentation had defined microaggressions as negative interactions with members of marginalized groups. Adams and Bhattacharya then clashed for a few minutes about how to define the term. It was a polite disagreement. Adams generally maintained that microaggression theory was a broad and important topic and that the slights caused real harm. Bhattacharya expressed a scientific skepticism that a microaggression could be distinguished from an unintentionally rude statement. His doubts were well-founded given that microaggression theory is not a particularly rigorous concept.

You can listen to the audio of this exchange here, beginning at about 28 minutes. Bhattacharya is respectful and calm, and is asking legitimate questions. It appears his main concern was the blanket vagueness of the term that allows anyone to claim a microaggression for almost any statement or act.

Apparently, the organizers of the event then decided that his questions were a microaggression in themselves, for which he must be punished.

Apollo 11 astronaut Michael Collins has passed away at 90

10:51 am

R.I.P. Michael Collins, the astronaut on Apollo 11 who stayed in lunar orbit while Neil Armstrong and Buzz Aldrin walked on the Moon, passed away today at the age of 90.

Collins was one of the most friendly and personable astronauts I ever met. He was always available and willing to answer questions, sometimes even willing to go an extra mile to provide you more than you asked for.

In many ways his later work as head of the Air & Space Museum was more important than his time as an astronaut. He helped make that museum and the history it documents one of the most popular in the world.

As long as humanity exists, on Earth and in space, Michael Collins will never be forgotten.

Perseverance as seen by Ingenuity

8:51 am

Perserverance as seen by Ingenuity
Click for full image.

Cool image time! JPL today released the photo to the right, cropped to post here. It was taken by the helicopter Ingenuity during its third flight on April 25th and shows the rover Perseverance at its left edge.

The horizon is tilted because the camera lens is very wide angle to capture as much terrain as possible and thus produces a fisheye curved distortion to the image’s periphery.

This image was taken as Ingenuity flew north about 160 feet away from Perseverance, probably in the first part of its flight as seen by photos taken by Perseverance of Ingenuity during its flight.

The mountains in the distance are the rim of Jezero Crater.

Dynetics has joined Blue Origin in protesting Starship contract by NASA

5:06 pm

Capitalism in space? Dynetics today joined Blue Origin in protesting NASA’s decision to award SpaceX the sole contract for building a manned lunar lander, using its Starship spacecraft.

Though the company’s protest did not going into specifics, it appears that Dynetics main complaint is the decision to not award two companies a contract, as originally planned. Even so, these factors make Dynetics bid quite problematic:

Of the three bidders, Dynetics was the lowest ranked. It had a technical rating of “Marginal,” one step below the “Acceptable” that Blue Origin and SpaceX received. Its Management rating of “Very Good” was the same as Blue Origin but one step below SpaceX’s “Outstanding.”

In the source selection statement, Kathy Lueders, NASA associate administrator for human exploration and operations, said the Dynetics lander “suffered from a number of serious drawbacks” that increased risk. The lander was overweight, which at this early stage of development “calls into question the feasibility of Dynetics’ mission architecture and its ability to successfully close its mission as proposed,” she wrote. The evaluation also questioned the maturity of the technology for performing in-space cryogenic fluid transfer required to refuel the lander, as the company planned.

Lueders concluded that “while Dynetics’ proposal does have some meritorious technical and management attributes, it is overall of limited merit and is only somewhat in alignment with the objectives as set forth in this solicitation.” The document only stated that Dynetics’ proposal had a price “significantly higher” than Blue Origin’s proposal, which in turn was significantly higher than SpaceX’s winning bid of $2.89 billion. Blue Origin disclosed in its protest that it bid $5.99 billion. [emphasis mine]

So, Dynetics proposed to build an overweight lander and do it at the highest price. If anything this protest enhances Blue Origin’s protest. It certainly doesn’t do much for Dynetics.

In fact, a good metaphor for the bidding here would be to imagine three vacuum cleaner salesman arriving at your door, all at the same time. One salesman, Mr. Newbie Dynetics, offers you a vacuum cleaner (as yet unbuilt in any form) that as presently designed will only be able to suck in about two-thirds of the dirt on your floor, and demands you pay $800 for it. The second salesman, Jeff “Blue” Origin, says his design (also unbuilt) is far better because they’ve done some successful tests of a tiny handheld prototype, and in addition he’ll only charge you $599 for it.

Neither Newbie or Jeff have any financing, so you will have to foot the entire bill.

The third salesman, Elon Starship, shows up with a full size prototype that while it has some problems, actually functions, and has been tested a number of times already. He also has more than two thirds of his development already financed by others, and only wants to charge you $289.

Who would you pick?

Since I know my readers are neither elected officials nor government officials in Washington and therefore know how to use their brains intelligently, I suspect I know.

We shall soon find out just how smart or dumb those elected officials or government officials in Washington really are.
