Gateway already behind schedule and mismanaged

11:47 am

Surprise, Surprise! According to a report by NASA’s inspector general released today [pdf], the agency’s Lunar Gateway space station project is already behind schedule, will likely not be available for any 2024 Artemis lunar mission, and apparently has been mismanaged in a manner that is raising costs.

Many of the problems appear to have been caused by NASA’s abrupt decision, ten months after awarding its contracts to Maxar and Northrop Grumman to build respectively the station’s service (PPE) and habitation (HALO) modules, to require that they both be launched on a single rocket, rather than separate launches as originally planned. From the report:

The decision to launch the PPE and HALO together, while avoiding the cost of a second commercial launch vehicle, has contributed to cost increases due to the redesign of several components, an elevated launch risk, and a longer duration flight to lunar orbit. In addition, due to the decision Maxar was forced to terminate its subcontract with Space Exploration Technologies Corp (SpaceX) for PPE launch services, even though Maxar had already paid SpaceX approximately $27.5 million for this service, a portion of which was paid by NASA prior to the termination. Further, a co-manifested launch increases risk because together the elements may be too heavy for commercially available rockets or too long for the rocket’s fairing, potentially impacting intended spacecraft mass, length, and other requirements.

While the Trump administration had already made the decision to not rely on Gateway for its hoped-for 2024 manned lunar landing, it still hoped to have it available for use. This now appears unlikely. The report today is very clear: “Gateway likely will not be in a position to support a 2024 lunar landing.”

None of this is really a surprise. If anything, it is a feature of Gateway, not a bug. The program was always intended as a big jobs program, funneling money to NASA contractors who would in turn set up operations in various important congressional districts. Like SLS and Orion, it is more important that the program get delayed while costing more than actually accomplish anything.

Even if a Biden administration (still not confirmed) takes over and decides to support this project (which I think will happen), do not expect it to take place as scheduled. At best, Gateway will not be operational for years yet, and in fact it could take until the ’30s to get it built and launched. And that slow and expensive schedule will be exactly what our corrupt politicians and government bureaucrats want.

Meanwhile, China will be setting up its bases on the Moon. And maybe so will SpaceX using Starship.

NASA offers public chance to experience next manned mission virtually

9:25 am

NASA is now offering the general public the opportunity to virtually experience the next manned Dragon flight to ISS, set to launch on November 14th.

“Members of the public can attend the launch virtually, receiving mission updates and opportunities normally reserved for on-site guests,” NASA officials wrote in a statement on Tuesday (Nov. 3). “NASA’s virtual launch experience for Crew-1 includes curated launch resources, a digital boarding pass, notifications about NASA social interactions and the opportunity for a virtual launch passport stamp following a successful launch,” the agency added.

While much of this will be fun to do, much of it is also pure hype, designed to sell NASA to the public, even though the mission is being launched and run almost entirely by the private commercial company SpaceX, not NASA.

Company defends its satellite constellation from NASA criticism

9:21 am

The founder of AST & Science, the company that wishes to launch a constellation of 243 communications satellites, has defended its effort from criticisms expressed by NASA in a comment to the FCC.

“We’re not a bunch of cowboys launching satellites,” said Abel Avellan, founder of AST & Science, in an interview. “This is a serious, well-funded project.” … Avellan said the “SpaceMobile” satellites do indeed have a very large cross-sectional area perpendicular to the ground, as this is the only way to deliver direct satellite-to-broadband signals. “There is no magic,” he said. “If you want something to connect directly to a handset, it’s not going to be a CubeSat.”

Each of the satellites will include a large antenna, comprising an area as large as 900 meters squared. However, Avellan said the satellites will fly edge-on, “like a frisbee, but without the spinning.” He said the satellites’ cross-section along the direction of motion is only about 3 meters squared. The company has calculated that the probability of a collision occurring at random—assuming no avoidance maneuver—to be only about 1-in-5,000 over its lifetime, or 1-in-20 across the entire constellation.

It appears that neither the company nor NASA has as yet begun direct discussions about these issues. NASA’s concerns however could seriously hamper the company’s future.

NASA officially expresses concerns about proposed private communications constellation

8:55 am

For what appears to be an unprecedented action, NASA has officially expressed opposition to a proposed private satellite constellation by the company AST & Science.

NASA’s position was released in a comment to the FCC, where the company has requested a communications license to operate its satellites.

At issue are plans put forth by AST & Science, which intends to build a constellation of more than 240 large satellites, essentially deploying “cell towers” in space to provide 4G and possibly 5G broadband connection directly to cell phones on Earth. The company, based in Midland, Texas, calls its constellation “SpaceMobile” and has raised an estimated $120 million.

The space agency felt compelled to comment on AST’s proposal for several reasons. Most notably, the proposed altitude for the SpaceMobile constellation lies near the “A-Train,” a group of 10 Earth-science monitoring satellites operated by NASA and the US Geological Survey, as well as partners in France and Japan. “Historical experience with the A-Train constellation has shown that this particular region of space tends to produce a large number of conjunctions between space objects,” the NASA letter states.

The satellites are also very large. In order to provide service, AST plans to build spacecraft with large phased array antennae—900 square meters. According to NASA, in planning for potential conjunctions with other satellites and debris in this orbit, this would require proscribing a “hard-body radius” of 30 meters, or as much as 10 times larger than other satellites.

Maneuvering around the proposed SpaceMobile constellation would be extraordinarily taxing, NASA said. “For the completed constellation of 243 satellites, one can expect 1,500 mitigation actions per year and perhaps 15,000 planning activities,” the space agency stated. “This would equate to four maneuvers and 40 active planning activities on any given day.”

The company has said it is willing to work with NASA to ease its concerns. For NASA to take this particular step however is most strange, especially considering the size of this constellation, 240 satellites. This number is tiny compared to the multi-thousands being proposed by SpaceX, Amazon, and OneWeb. Their large size footprint certainly could be a factor, but it does seem puzzling for the space agency to pick out this particular constellation for opposition, and none of the others.

Signal to Voyager-2 confirms upgrade of NASA’s Deep Space Network

8:42 am

After months of downtime in order to install a major and very badly needed upgrade to NASA’s Deep Space Network (DSN) (the worldwide array of radio dishes used to communicate with planetary probes throughout the solar system) a test command to Voyager-2 beyond the orbit of Pluto was sent, received, and executed successfully this week, proving the upgrade is working.

The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2. Located in Canberra, Australia, it is part of NASA’s Deep Space Network (DSN), a collection of radio antennas around the world used primarily to communicate with spacecraft operating beyond the Moon. Since the dish went offline, mission operators have been able to receive health updates and science data from Voyager 2, but they haven’t been able to send commands to the far-flung probe, which has traveled billions of miles from Earth since its 1977 launch.

Among the upgrades to DSS43, as the dish is known, are two new radio transmitters. One of them, which is used to talk with Voyager 2, hasn’t been replaced in over 47 years. Engineers have also upgraded heating and cooling equipment, power supply equipment, and other electronics needed to run the new transmitters.

The successful call to Voyager 2 is just one indication that the dish will be back online in February 2021.

The upgrade has been overdue for years, and is essential to provide sufficient communications capability for the future interplanetary mission presently planned.

NASA and ESA ink Lunar Gateway deal

9:09 am

NASA yesterday announced that it has signed a deal with the European Space Agency (ESA) outlining their partnership in building the Lunar Gateway space station in orbit around the Moon.

Under this agreement, ESA will contribute habitation and refueling modules, along with enhanced lunar communications, to the Gateway. The refueling module also will include crew observation windows. In addition to providing the hardware, ESA will be responsible for operations of the Gateway elements it provides. ESA also provides two additional European Service Modules (ESMs) for NASA’s Orion spacecraft. These ESMs will propel and power Orion in space on future Artemis missions and provide air and water for its crew.

For some reason NASA’s press release makes no mention of what ESA gets from the deal. From this news report:

[ESA] said it will receive “three flight opportunities for European astronauts to travel to and work on the Gateway” as part of the agreement.

I also note that there is no mention of the Artemis Accords in this agreement. As far as I can tell, right now the only ESA member who has signed on is the United Kingdom, and I am not sure of the UK’s status in the ESA considering their exit from the European Union. The two are different political deals, but exiting one might affect the other.

The Trump administration has said repeatedly that it will only partner in its lunar ambitions with countries that sign the accords. However, at this moment Congress has simply not funded those ambitions, so NASA needs partners to get things built. Moreover, Orion is a space capsule (costing about $18 billion and taking 20 years to build) that does not have a service module to provide it air and water. Europe provides that, and had only agreed to build two.

It might be that NASA has traded the accords away to get Europe’s help for both Gateway and Orion. This deal, announced now, might also be an effort by NASA (and Europe) to lobby Congress to fork up the cash.

SpaceX identifies problem with several engines on booster, requiring replacement

9:51 am

Capitalism in space: SpaceX has identified the issue with several engines on the first stage that caused a launch abort for an Air Force GPS satellite and has replaced those engines.

Since Falcon 9 B1062 suffered a rare last-second launch abort on October 2nd, SpaceX has discovered an issue with several new Merlin 1D booster engines and apparently removed affected engines from Falcon 9 booster B1062, shipped the engines to McGregor, Texas for testing, characterized the bad behavior, and implemented a fix capable of satisfying their strictest customers (NASA and the US military) in roughly three weeks.

The immediate fix appears to be replacing the engines for now as they troubleshoot the issue. They have now rescheduled the launch of the GPS satellite for November 5th.

It also appears that because the company has identified the engine issue and can spot it on any engine it uses, NASA has agreed to set a November 14th launch date for the next manned Dragon mission. They will hold a press conference tomorrow to outline the situation in more detail.

Space officials, from in and out of NASA, meet to plan Biden administration space policy

10:25 am

A group of senior space officials from both inside and outside of NASA held a closed door “war game” on October 20th, designed to plan out what they thought should be the space policy of the Biden administration.

About a dozen officials participated. Attendees included two former astronauts, Charlie Bolden and Pam Melroy, who have worked in space policy since their retirements. Bolden was NASA administrator under President Obama. Also participating were two former senior NASA officials—Mike French, chief of staff under Bolden, and Doug Loverro, a chief of human spaceflight for the Trump administration. Loverro was forced to step down in February and is now under investigation for improper contact with Boeing. The meeting also had participation from industry, including entrepreneur Rick Tumlinson and Marc Berkowitz of Lockheed Martin.

They claim that this is not at the behest of the Biden campaign, but what I see is a group of high-level bureaucrats from Washington gathering together to plan space policy strategy for Biden, with the expectation that should he win they will be well placed to inaugurate his policy for him.

The article did not name all the participants, but if any are presently working in the Trump administration or in NASA their participation in this “war game” was highly inappropriate. It is not their place to set policy, only to implement the policy determined by the elected president now in office.

Should Trump win on November 3rd, the attendance list of participants will thus provide a good guide on who not to hire, as well as who to fire should Trump’s new looser policy on hiring and firing take effect. These individuals have now signaled their partisan loyalties, and it isn’t with Trump or the Republicans. If any are part of his administration now they are wolves in sheep’s clothing, likely acting against his interests when no one is looking.

On this topic, I just bought this book “The Memo: 20 Years Inside the Deep State Fighting for America First,” based on this review, which states:

Higgins’ new book, “The Memo: 20 Years Inside the Deep State Fighting for America First,” is an eye-opening and unique book for a political memoir. It is not heavy on political wonkiness, policymaking stratagems, and personal vendettas typical of Washington, DC tell-alls. It is a refreshingly direct tale of a talented young man’s rise from the enlisted ranks of the military into politics and then policy-making, only to discover the realities of a brutal and seditious opposition fighting to preserve a decrepit, America-destroying agenda that culminated in an outrageous coup attempt against a U.S. president.

And while Higgins does “name names” in his book, when describing the subversion of the Trump agenda by those inimical to it, he does so only to drive home his larger point about the incredible obstacles President Trump has faced in orienting U.S. policies toward advancing his America-first agenda.

Seems very apropos at this moment in time.

Sample grab appears to be a success at Bennu

3:17 pm

OSIRIS-REx has apparently successfully touched the surface of Bennu, grabbed a sample, and backed away without damage.

The link takes you to my embed of NASA’s live stream, which is mostly pr garbage. However, it is providing live updates from the mission control team, as it happens. Most of time, the NASA people running their pr effort even have the sense to shut up when such updates come it.

Right now we do not know how much of a sample was obtained. It will take some analysis of data and images to find out. They will know by the time of tomorrow’s press conference at 5 pm (Eastern).

First full static fire test of SLS’s core stage scheduled for November 14

10:02 am

NASA has now scheduled the first full static fire test of the core stage of its SLS rockt for no earlier than November 14th.

Currently installed in the B-2 Test Stand at NASA’s Stennis Space Center in Mississippi, the massive 212-foot-tall core stage has completed six of eight planned green run tests before it can be shipped to KSC by barge as the final piece of the first mission of the Artemis program, slated for launch in November 2021.

Officials with NASA as well as contractors Boeing and Aerojet Rocketdyne gave an update on the core stage progress on Tuesday, stating the tentative date for the hot fire test is Nov. 14, and the target for it to be loaded onto the Pegasus barge for the trip to Florida is Jan. 14.

“So far the design has held together extremely well. We’ve not really had any surprises,” said John Shannon, Boeing’s vice president and program manager for the Space Launch System.

Unlike SpaceX, which uses tests like this to figure out how to build its rockets, NASA uses these tests to confirm its designs and construction at the very end of development. This difference in approach, now so clearly illustrated by simultaneous tests going on from both, I think shows the advantages of SpaceX’s approach. By testing during development, SpaceX can quickly fix any problems it finds, and move forward fast with better designs. This approach also results in a less expensive final result.

NASA instead must make sure its designs are perfect on the drafting board, which therefore requires their engineers to include gigantic design margins, resulting in long construction schedules and an expensive final product. Worst of all, should SLS fail during this final test, NASA will face some very difficult and expensive choices, none good.

NASA awards $370 million to 14 companies to develop new space capabilities

9:27 am

Capitalism in space: NASA yesterday issued fifteen development contracts to fourteen private space companies, totaling $370 million, to help them develop a variety of new space capabilities.

The funding is spread across 15 contracts to 14 different companies, including SpaceX, Astrobotic, Lockheed Martin, United Launch Alliance and Intuitive Machines.

Nearly 70% of the money is earmarked for the management of cryogenic fluids such as liquid hydrogen and liquid oxygen. SpaceX, for example, will get $53 million for an in-space demonstration that will transfer 11 tons (10 metric tons) of liquid oxygen between tanks on one of its next-gen Starship vehicles.

What makes these contracts different from past NASA development contracts is fundamental. First, the design work comes from the companies, not NASA. Therefore products will be designed with the company’s needs in mind, not the government’s, and will also likely be designed faster and more efficiently.

Second, the companies will own what they build, and will be able to sell or use it however they wish. SpaceX for example wants this capability to give Starship the ability to leave Earth orbit, for its own commercial flights.

Russia oxygen regeneration system on ISS fails

9:04 am

Russian new sources today reported that their oxygen regeneration system on the ISS module Zvezda has failed.

A Russian cosmonaut told a specialist from the Mission Control Centre in the Moscow Region that the Electron-VM OGS installed in the Russian Zvezda module had failed.

Essentially this information was overheard by Russian sources during communications between mission control and the Russians on-board ISS.

Whether this failure is related to the rise in temperature this week in Zvezda is unknown. Also, the failed unit itself might be one that came with the station when it was launched 20 years ago, or it might be an upgraded unit launched later.

This unit is designed to recycle oxygen on board so as to reduce the need to haul up new supplies. Its failure poses no immediate threat to the station or its crew, since there is plenty of oxygen store on board and the U.S. has its own regeneration unit. However, if it isn’t repairable and can’t be replaced quickly it likely means future cargo manifests will require larger stocks of oxygen. It also might mean a reduction in total crew on ISS, which only now is returning to more than three for long periods because of the initiation of American private ferrying serves.

Meanwhile the location of the leak on Zvezda remains unknown. It needs to be pinpointed and hopefully solved, because if it is a more serious age issue ISS managers need to know.
