NASA awards small study contract to orbital tug company Starfish Space

9:24 am

Capitalism in space: NASA has awarded a small three-month study contract to the U.S. orbital tug company Starfish Space, to consider using its Otter orbital tug to rendezvous and inspect defunct orbital debris.

The award amount was not released, suggesting this is a very small contract designed simply to see if the company’s technology warrants a larger contract.

Some of those features — including Starfish’s Cetacean relative navigation software and its Cephalopod autonomous guidance software — could be tested sometime in the next few months on the company’s Otter Pup prototype spacecraft, which was sent into orbit in June but was forced into an unfortunate spin during deployment. Starfish stabilized the spin in August and is currently making sure that all of Otter Pup’s systems are in working order for future tests.

NASA’s follow-up contract, awarded through the space agency’s Small Business Innovation Research program, or SBIR, calls for Starfish to assess the feasibility of using its full-scale Otter satellite servicing vehicle to rendezvous with large pieces of space debris and inspect them.

This contract is comparable in goals to the one NASA issued to Astroscale earlier this week, though much smaller.

Capitalism in space: The commercial lunar lander company Intuitive Machines yesterday unveiled its now ready-for-launch Nova-C lander, set for launch on a Falcon 9 rocket during a six-day launch window beginning on November 16, 2023.

Steve Altemus, chief executive of Intuitive Machines, estimated the odds of success at “upwards of 65% to 75%,” higher than the historical average. That’s based, he said, on the experience the company has built up with key technologies on the lander, such as precision landing and its propulsion system.

It is also based on lessons learned from those failed missions. “Each one of those things that we witnessed in terms of anomalies that caused the failures of those missions, we have internalized,” he said. “Therefore, I think our odds are higher.”

If successful, Nova-C will land closer to the Moon’s south pole than any previous lander, as shown on the map to the right, and will function like India’s Pragyan rover for one lunar day, about two weeks. It will also land right next to a crater with a permanently shadowed interior, though it will have no way to travel into it. The company also two more lunar lander contracts with NASA, with the second Nova-C mission scheduled for 2024, and a third not yet scheduled.

Armstrong and Miller – The Art Historian’s Most Clumsiest Moments

6:01 pm

An evening pause: Ben Miller of the Armstrong and Miller show does a series of wonderful send-ups of the typical narrator/anchor of public television documentaries. This short skit appears to have been a regular running gag on their show. More funny routines here.

Today’s blacklisted American: Anti-religion group insists college football coaches have no 1st amendment rights

1:48 pm

Freedom from Religion Foundation: hostile to freedom

They’re coming for you next: To get an idea the level of intolerance that now pervades America, one need only review the effort of the Freedom from Religion Foundation (FFRF) to deny all first amendment religious rights to anyone who happens to work for a public university or institution.

Repeatedly FFRF takes legal action to gag any religious expression by public employees, regardless of whether they do it at work or on their own personal time. In the past, there might have been some valid arguments or situations where it was inappropriate for a public employee to push his or her religious beliefs, but nowadays organizations like FFRF define any religious activity by such employees, at any time, to be illegal and a violation of the so-called “separation of church and state” claimed by them to be the purpose behind the first amendment, when its real purpose has always been to make sure all citizens will be free to express their opinions and personal religion without government intervention.

In January, FFRF attempted to silence Deon Sanders, the football coach at the University of Colorado, because he repeatedly expressed his Christian faith in public, and asked his players to participate. According to its January letter to the University of Colorado [pdf], the University must gag Sanders.

The Netherlands says it will sign Artemis Accords

12:13 pm

According to a press release from the government of the Netherlands yesterday, it plans to sign the Artemis Accords, becoming the thirtieth nation to join the American alliance to explore and settle the solar system.

The full list of signatories to the Artemis Accords is now as follows: Argentina, Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, Germany, India, Israel, Italy, Japan, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

Increasingly the entire western world is signing on, leaving China, Russia, and their few communist allies isolated on the other side.

Though this sounds good, we must remember that the west no longer stands as firmly for freedom and individual rights as it did during the Cold War. Instead, we increasingly see two alliances that are both more interested in promoting the power of the people who run each, rather than furthering the rights and dreams of their citizens. As I concluded in Conscious Choice:

It is therefore likely that the first few centuries of colonization throughout the solar system will not proceed peacefully or justly, as wished for by the good intentions of the Outer Space Treaty. Instead, the initial exploration will be a brutal legal nightmare for all involved.

Governments will scramble to grab as much as they can. And for private enterprise to succeed in space, the treaty’s restrictions on property rights will force those operations, very expensive, time consuming and extremely risky, to focus on maximizing profits so as to at least minimize the legal risks. Meanwhile, ordinary citizens will have few legal rights, because the rights citizens enjoy on Earth will not exist legally for them.

We are certainly going to explore and settle the solar system in the coming centuries. It is also likely that the citizens living there will have a terrible battle to obtain the same rights we on Earth have since the Enlightenment taken for granted.

Sunspot update: Activity rises in September but not significantly

11:15 am

Another month has passed, and it is once again time to post my annotated graph of NOAA’s monthly update of its graph that tracks the number of sunspots on the Sun’s Earth-facing hemisphere. The new graph is posted below, with several additional details to provide some larger context.

Last month we saw a drastic drop in August of sunspot activity, suggesting that the next maximum might possibly have been reached, though many months earlier than predicted. This month’s graph below, which shows an increase in activity in September but still well below the highs seen in June and July, strengthens that conclusion.

FAA issues new revised regulations for private commercial manned space

9:48 am

The FAA on September 28, 2023 issued new revised safety regulations for the emerging private commercial manned space industry, updating the regulations first put forth in 2014.

The recommendations, which are the first since 2014, cover the gamut across design, manufacturing, and operations, and are based on lessons learned during the NASA Commercial Crew program, as well as recent commercial space fights, the FAA said Friday. “AST [the FAA office that handles commercial space] is issuing Version 2 of this document because significant progress has been made in the commercial human space flight industry since 2014, the year Version 1 was issued.”

These new recommendations were worked out by a committee that included many of the private companies that now fly space passengers, such as SpaceX, Virgin Galactic, Blue Origin, and Boeing. Thus, the changes likely make some sense.

At the same time, it seems the effort to regulate has accelerated since Joe Biden became president. Under Trump there was a concerted effort to limit the impact of new regulations on this new space industry. Under Biden, it appears new regulations arrive almost weekly, and as a result there appears to be a significant slow down in development by new space companies.

FCC fines Dish for failing to put a geosynchronous satellite in its proper graveyard orbit

9:39 am

The FCC on October 2, 2023 announced it is fining Dish Network $150K for failing to raise the orbit of one of its dying geosynchronous satellites so that it was in a proper graveyard orbit and out of the way.

The settlement includes an admission of liability from Dish for leaving EchoStar-7 at 122 kilometers above its operational geostationary arc, less than halfway to where the satellite broadcaster had agreed. EchoStar-7 could pose orbital debris concerns at this lower altitude, the FCC warned.

The regulator said it approved a plan from Dish in 2012 to move the satellite at the end of its mission 300 kilometers above geostationary orbit, which is about 35,786 kilometers above the Earth. Dish had estimated it would need to start moving the satellite in May 2022 to ensure it had enough fuel for the trip after two decades in orbit — but just three months ahead of the planned move the company found insufficient propellant remaining.

It is routine for satellite companies to raise the orbits of their geosynchonous satellites when their lifespan is over in order to make room for future satellites. This higher orbit, long dubbed a graveyard orbit, is presently filled with many past satellites no longer in use (though the refueling and reusing of some is now taking place).

What makes this story different is the fine. The FCC has claimed it has the right to regulate the de-orbiting plans for all satellites, even though its statutory authority does not include that right. This fine is the first since the agency made that claim. That Dish settled rather than fight was likely a decision by managment to choose the lesser evil. Even though the courts would likely cancel the fine, the fight would cost as much as the fine, and there is a chance Dish would lose. As the saying goes, better to pay the two dollars than end up in jail.

As a result, this government agency has now established a precedent whereby it can regulate and even fine private companies for not doing what it dictates when it comes to decommissioning satellites, even though no law was ever passed giving it that power. And the FCC agrees.

“This is a breakthrough settlement,” FCC Enforcement Bureau Chief Loyaan Egal said in a statement, “making very clear the FCC has strong enforcement authority and capability to enforce its vitally important space debris rules.”

The unelected administrative state continues its unstoppable growth in power.

Northrop Grumman cancelling its NASA space station project?

9:22 am

According to anonymous sources, Northrop Grumman — one of four company partnerships chosen by NASA to build private commercial space stations to replace ISS — is considering cancelling its project for NASA.

At the International Astronautical Congress meeting this week in Azerbaijan, sources report that there is widespread speculation that one of these four companies, Northrop Grumman, is dropping out of the competition. Northrop’s plan had been to leverage its successful Cygnus spacecraft design to build a free-flying space station.

However, Northrop no longer plans to do so. Rather, it will join the venture backed by Voyager Space, which is partnering with Europe-based Airbus to develop a commercial space station. It’s likely that Northrop would provide cargo transportation services, with Cygnus as part of the team. Officials from Voyager and Northrop Grumman declined to comment on the change in strategy, which could be announced soon.

The original four were Axiom, Voyager Space (then called Nanoracks), Northrop Grumman, and Blue Origin. By teaming up with Voyager Space the number would drop to three, with Northrop simply providing freighter service to Voyager’s station.

Nor is this the only rumored change to these station projects. Last week sources suggested that the partnership between Blue Origin and Sierra Space was breaking up. If so, it remains unclear how that would effect its project for NASA.

These changes to the four proposed NASA stations would leave only Axiom’s space station unchanged and on its original course. Meanwhile, another company, Vast, is developing its own independent station, and SpaceX is considering developing a space station version of Starship.

All these shifts and changes are not to be unexpected, nor are they really bad news. They simply indicate the uncertain nature of any new product, even if that product is as unconventional as a private space station.

Psyche engineers discover and fix a major thruster problem only two weeks before launch

9:03 am

In a stroke of luck, the engineering team for the asteroid probe Psyche discovered an attitude thruster problem only two weeks before launch that could have destroyed the mission, and were able to fix it quickly.

The issue was discovered during pre-flight tests that showed the settings used to operate the thrusters were incorrect. At the planned 80 percent power level, analysis indicated higher-than-expected temperatures could cause damage.

As it turned out, the fix did not require any hardware or software changes. Just an updated table of parameters used by the probe’s flight computer, instructing it to fire the thrusters at what amounts to a lower power level. Maneuvers will take longer to complete, but that will not affect the mission.

Nonetheless, this problem should not have been discovered so late, and suggests that the management issues from other software problems that forced a year delay in the launch last year have not been completely solved. If I was the project scientist for this mission, I would be very uncomfortable about its future.

Hopefully, no more serious problems will occur, and after its Falcon Heavy launch on October 12 it will fly past Mars to aim for an August 2029 arrival at the metal asteroid Psyche.

SLIM leaves Earth orbit and is on its way to the Moon

SLIM's planned route to the Moon

The Japanese lunar lander SLIM fired its engines on September 30, 2023 to begin its journey to the Moon. The map to the right indicates the planned route after this trans-lunar injection burn, first flying past the Moon to put it on a trajectory that will bring it back to the Moon at the proper speed and direction for its landing several months hence.

The main goal of this mission is engineering, to test the ability of an autonomous unmanned spacecraft to land precisely within a small target zone about 300 feet across. If proven, this ability will make it possible to send unmanned landers to many places that are presently impossible due to their rough topography.

The route that SLIM is taking to the Moon is also unusual, and is probably also an engineering test of its own. Flybys of planets to change a spacecraft’s path is not a new technique, but in the past it has been used to slingshot the probe to another object, not send it back to that planet.
