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.

Juno science team proposes fly-bys of Jupiter’s moons

8:30 am

The Juno science team has proposed doing fly-bys of three of Jupiter’s moons, should NASA extend the mission beyond ’21.

Juno’s five-year primary mission phase ends in July 2021, and mission managers have proposed an extension that would continue operations until September 2025. The spacecraft’s additional orbits around Jupiter will bring Juno closer to the planet’s moons, allowing for a more diversified set of scientific targets.

…The moon flybys would begin in mid-2021 with an encounter with Ganymede, Jupiter’s largest moon, at a distance of roughly 600 miles (1,000 kilometers), according to Bolton.

After a series of distant passes, Juno would swoop just 200 miles (320 kilometers) above Europa in late 2022 for a high-speed flyby. Only NASA’s Galileo spacecraft, which ended its mission in 2003, has come closer to Europa.

There are two encounters with Jupiter’s volcanic moon Io planned in 2024 at distances of about 900 miles (1,500 kilometers), according to the flight plan presented by Bolton last month.

The extended mission would also allow scientists to get a better look at Jupiter’s north pole.

NASA will decide on the extension by the end of the year. From a cost and scientific perspective, it makes perfect sense to extend this mission for as long as possible. Compared to launching a new mission, extending an active one is far cheaper. It is also already in place.

Leak search on ISS narrows further

9:25 am

Further work on ISS by the astronauts has now narrowed the location of the station’s long-term slow leak to the aft area of the Russian Zvezda module.

As of Monday, the station crew had not located the precise site of the leak, but officials believe they have traced it to a transfer compartment at the rear section of the Zvezda module, near an aft docking port where a Russian Progress resupply freighter is attached.

The rate of leak continues to be slow and thus not any danger to the crew. It is also a concern, as it could become a safety issue should it increase. They want to find it and patch it. Furthermore, Zvezda is ISS’s second oldest module, launched in 2000. If this leak is a sign of that age is even more essential to know.

Two launches scheduled for tonight, 27 minutes apart

9:08 am

The numerous launch scrubs this past week has created an unprecedented situation tonight, two orbital launches scheduled only 27 minutes apart from two different East Coast spaceports.

First Northrop Grumman will try again to launch its Cygnus cargo freighter to ISS from Wallops Island, Virginia, with the launch scheduled for 9:12 pm (Eastern). The first launch attempt last night was aborted 2:21 seconds before liftoff “after receiving off-nominal data from ground support equipment.”

Second, SpaceX will try to launch two Air Force GPS satellites from Cape Canaveral, Florida, with the launch scheduled for 9:43 pm (Eastern). This launch has been delayed several times because of the repeated launch scrubs of ULA’s Delta 4 Heavy rocket, attempting to launch a military reconnaissance satellite. ULA’s launch had priority for the range, but with it delayed due to the investigation over the T-7 second launch abort on September 30th, the SpaceX’s GPS launch moves up in line.

The first will be live streamed on NASA TV, the second by SpaceX. I have embedded the live streams for both below the fold.

Leak on ISS located?

3:57 pm

According to Business Insider article , engineers have finally narrowed the location of the slow leak on ISS to the Russian Zvezda module.

NASA and Roscosmos, Russia’s space agency, had already narrowed down the likely location of the leak to several modules on the station’s Russian side.

So astronaut Chris Cassidy and cosmonauts Anatoly Ivanishin and Ivan Vagner tested those modules by shutting the hatches between each one and using an ultrasonic leak detector to collect data through the night. The tool measures noise caused by airflow too quiet for humans to hear.

By Tuesday morning, they’d figured out that the leak is in the Zvezda Service Module, the main module on the station’s Russian side. Zvezda provides that half of the station with oxygen and drinkable water, and it’s also equipped with a machine that scrubs carbon dioxide from the air. The module contains the section’s sleeping quarters, dining room, refrigerator, freezer, and bathroom.

They don’t yet know where in the module the leak is located, but at least they know at last where to look.

This module was the second module launched to ISS, launching in 2000. Thus, the leak could not have come from any construction workers from the ground. More likely its age has resulted in something changing. This needs to be fixed, but at the moment the situation is not critical.

NASA & SpaceX set Oct 31st for next manned Dragon mission

9:22 am

Capitalism in space: NASA and SpaceX have now scheduled Oct 31st as the target launch date for the first operational manned Dragon mission to ISS, the second manned Dragon mission overall.

This new date delays the launch a week from the previous announced schedule, and was done to give some space between its launch and the launch of a manned Soyuz on October 14th and the return of a different Soyuz with the present ISS crew on October 21st.

Axiom, SpaceX, and NASA finalizing first wholly private manned mission

12:38 pm

Capitalism in space: Axiom, SpaceX, and NASA are close to finalizing the deal for the first wholly private manned mission to ISS, tentatively set for October 2021.

One of the topics Axiom is negotiating with NASA involves how much insight the space agency will have into the private astronaut mission. While the Axiom missions will be managed by commercial companies, the AX-1 flight will fly with a reusable Crew Dragon spacecraft that will carry NASA astronauts on other missions. “There’s a certain amount of insight (NASA) would like on our flight, on a commercial flight,” [Axiom official] Suffredini said Friday. “So that is one aspect of that process. We’re using a vehicle that is going to be re-flown, and NASA will certify the re-flights because they want to do re-flights.”

Axiom and SpaceX will also have to confirm a schedule with NASA for the AX-1 mission to dock with the space station. The orbiting research complex has a busy schedule of arriving and departing crew and cargo vehicles, and managers also have slot in spacecraft dockings amid spacewalks, experiments, and other critical operations.

NASA also oversees safety of the space station with the program’s international partners.

The private companies however will in the end be responsible for the flight.

There have been rumors that the passengers on this flight will be Tom Cruise and his film director, though this is not confirmed. Also, these same arrangements will be used for the tentative 2023 private flight of the winner of a proposed reality television show dubbed Space Hero.

NASA lays out Artemis budget and plan to get astronauts to Moon

10:10 am

In a obvious lobbying effort to get Congress to fund the Trump administration’s Artemis project to land humans on the Moon by 2024, NASA yesterday released a new updated plan and budget for the program.

More here.

The document [pdf] outlines the specific plans for each of the first three Artemis flights, with the first unmanned, the second manned and designed to fly around the Moon, and the third to land a man and a woman on the Moon. Overall the plan is budgeted at about $28 billion, with $3.2 billion needed immediately to fund construction of the lunar lander. From the second link:

Bridenstine said he remains optimistic Congress will fully fund lander development because of what he described as broad bipartisan support for the Artemis program. He said he’s hopeful an expected continuing resolution that would freeze NASA’s budget at last year’s spending levels will be resolved in an “omnibus” spending bill before Christmas or, if the CR is extended, by early spring. “It is critically important that we get that $3.2 billion,” he said. “And I think that if we can have that done before Christmas, we’re still on track for a 2024 moon landing. … If we go beyond March, and we still don’t have the human landing system funded, it becomes increasingly more difficult.”

And what happens then?

“It’s really simple. If Congress doesn’t fund the moon landing program, then it won’t be achieved (in 2024), I mean it’s really that simple,” Bridenstine said. But he quickly added: “I want to be clear, if they push the funding off, our goal will be to get to the moon at the earliest possible opportunity.”

I remain doubtful the present Congress, with the House controlled by the Democrats, will fund this 2024 lunar landing. Since 2016 the entire political platform of the Democratic Party has been “oppose anything Trump.” They will not fund this project if it means he will get this landing during his second term.

If however Trump loses in November, the lame duck Congress might then go ahead and fund it before December, since the landing in 2024 will then occur during the Biden presidency.

Technically the plan reveals that NASA is trying to accelerate the development of the rendezvous and docking software for Orion. During the second flight, the first manned, the crew will do proximity maneuvers with the upper stage of the rocket. Under previous management NASA had not included this ability, as they had not planned to have Orion do any rendezvouses or dockings. That lack makes it impossible for Orion to fly on any other rocket but SLS. This change means the Trump administration recognizes this is a problem, and wants to fix it, especially because they also recognize that SLS is a poor long term option for future lunar missions.

UAE to train astronauts at NASA

9:29 am

The United Arab Emirates has signed an agreement with NASA to train its two future astronauts to ISS.

UAE astronauts Hazzaa AlMansoori and Sultan AlNeyadi have already begun their training at Nasa’s Johnson Space Center in Houston starting Monday, Salem AlMarri, head of the UAE Astronaut Programme, at the Mohammed Bin Rashid Space Centre (MBRSC), said during a media briefing. AlMansoori and AlNeyadi had earlier trained at the Yuri Gagarin Cosmonaut Training Center in Star City, Moscow, in September 2018 as part of their preparation for their launch to the ISS.

The two men will be launched to ISS by Russia using its Soyuz rocket and capsule. However, the UAE is smart to get them training in the U.S., as they need to work with U.S. mission control and U.S. systems on ISS. Moreover, I expect the UAE might wish to buy tickets eventually on either Dragon or Starliner, and this training lays the groundwork for that possibility.

First manned Artemis Moon mission might not go to south pole

3:59 pm

In order to meet the Trump administration’s 2024 deadline for the first Artemis manned lunar landing, NASA is now considering sending that first mission to an equatorial target, rather than the Moon’s south pole.

The Artemis program landing site issue came up at two separate events with agency leaders this week, beginning with NASA Administrator Jim Bridenstine’s comments to open a digital meeting held by a NASA advisory group called the Lunar Exploration Analysis Group, on Monday (Sept. 14).

“For the first mission, Artemis 3, our objective is to get to the south pole,” Bridenstine said. “But … it would not surprise me if, for example, if we made a determination that the south pole might be out of reach for Artemis 3, which I’m not saying it is or isn’t,” interest in the Apollo sites may win out.

The engineering to get to the polar regions is more challenging, so rather than delay that first mission they are considering simplifying it instead.

The fact remains that Congress has still not funded any Artemis missions beyond the first unmanned and first manned flights, neither of which will land on the Moon. Whether that money will ever be forthcoming really depends entirely on the November election, as well as the success or failure of the upcoming full-up static fire engine test of the SLS first stage.

NASA reorganizes its manned space bureaucracy

10:10 am

Gotta rearrange those deck chairs! NASA has finally completed a long-planned reorganization of its manned space bureaucracy, first begun several years ago.

At a Sept. 16 Washington Space Business Roundtable webinar, Kathy Lueders, who took over as NASA associate administrator for human exploration and operations three months ago, said that NASA Associate Administrator Steve Jurczyk formally approved a reorganization of her mission directorate the previous day. “It addressed some of the concerns that folks have had and is really getting us set up for our future missions going forward,” she said of the reorganization.

Those concerns include findings from a review called a Program Status Assessment carried out earlier this year. That review cited issues with system engineering oversight for the Artemis program and a lack of a formal Artemis program organization. “We are also using these adjustments to solidify and better define division roles,” the agency said in a statement to SpaceNews.

NASA does this Potemkin-type reorganization about once every decade or so, with little major effect other than to allow the upper management preen itself as it makes believe it has accomplished something. This particular rearrangement however might be a bit more beneficial that past ones, in that it appears aimed at aligning the agency’s bureaucracy with its new status of being a customer of the private sector, rather than its boss and overseer.

NASA to buy lunar mined material from private companies

8:43 am

Capitalism in space: NASA yesterday announced that, rather than develop its own lunar sample missions, it wants to buy such lunar mined material obtained from private companies.

NASA on Thursday launched an effort to pay companies to mine resources on the moon, announcing it would buy from them rocks, dirt and other lunar materials as the U.S. space agency seeks to spur private extraction of coveted off-world resources for its use.

NASA Administrator Jim Bridenstine wrote in a blog post accompanying the announcement that the plans would not violate a 1967 treaty that holds that celestial bodies and space are exempt from national claims of ownership.

The initiative, targeting companies that plan to send robots to mine lunar resources, is part of NASA’s goal of setting what Bridenstine called “norms of behavior” in space and allowing private mining on the moon in ways that could help sustain future astronaut missions. NASA said it views the mined resources as the property of the company, and the materials would become “the sole property of NASA” after purchase.

This announcement continues NASA’s transition under the Trump administration from trying to run everything to simply being a customer buying what it needs and wants from the private sector. The idea is smart, as it will guarantee that these samples will be obtained in the cheapest and fastest way possible, while simultaneously sparking the development of a competitive and thriving private industry capable of flying all kinds of planetary missions. The lower costs of these private planetary probes will in turn will spark the creation of a new private sector of customers buying those probes for their own profit-centered needs.

Boeing strikes deal to avoid harsher ethics probe in NASA’s lunar lander scandal

3:07 pm

Boeing has struck a deal with both NASA and the Air Force in order to avoid a harsher and more extensive ethics probe into its part in the NASA lunar lander contract bidding scandal.

The agreement, signed in August, comes as federal prosecutors continue a criminal investigation into whether NASA’s former human exploration chief, Doug Loverro, improperly guided Boeing space executive Jim Chilton during the contract bidding process.

By agreeing to the “Compliance Program Enhancements”, the aerospace heavyweight staves off harsher consequences from NASA and the Air Force – its space division’s top customers – such as being suspended or debarred from bidding on future space contracts. The agreement calls for Boeing to pay a “third party expert” to assess its ethics and compliance programs and review training procedures for executives who liaise with government officials, citing “concerns related to procurement integrity” during NASA’s Human Landing System competition.

Since Loverro resigned in May, Boeing has fired one company attorney and a group of mid-level employees, three people familiar with the actions told Reuters.

The deal seems like a bureaucratic whitewash, designed to take the heat off the company. And since Boeing as a company has many problems, I remain skeptical that any of this will make a difference in getting things fixed.

NASA solicits lunar landers to bid on bringing science instruments to Moon

8:56 am

UPDATE: It appears I misunderstood the nature of this NASA solicitation in my initial post. I have rewritten it to correct it. Hat tip reader Rex Ridenoure.

Capitalism in space: NASA has issued a request from the private companies building unmanned lunar landers to bid on carrying a variety of science instruments to the Moon by ’23.

Initially NASA had indicated it was farming out the design and construction of the lunar landers to private companies, but would have the science instruments designed and built in-house. Since ’19 however NASA has had private companies designing and building these fourteen small science payloads, and is now in the process of determining which private landers will bring them to the Moon.

Though this approach is not very different than past NASA arrangements, what is different is NASA’s public approach. Instead of touting NASA’s part in this work, the agency is touting the work of the private companies.

Northrop Grumman successfully tests SLS solid rocket booster

9:03 am

Northrop Grumman yesterday successfully test fired a solid rocket booster to confirm its design for use on NASA’s long-delayed and overbudget SLS rocket.

The test, completed at the T97 test area at Northrop Grumman‘s facility in Promontory, Utah, took place on Wednesday, September 2, 2020, at 1:05 PM Mountain Daylight Time (19:05 UTC). A single five-segment SLS solid rocket motor with a thrust of up to 3.6 million pounds was ignited, and burned for approximately two minutes.

The booster is an expanded version of the solid rocket boosters used on the space shuttle, with five segments instead of four, and in fact will use previously flown segments from past shuttle launches. Since this booster will not be recovered, these launches will be the last time those segments fly.

SpaceX wins launch contract for unmanned lunar lander

11:24 am

Capitalism in space: Masten Space Systems has awarded SpaceX the launch contract for its unmanned lunar lander, being built to carry nine NASA science payloads to the south pole of the Moon.

Launch is tentatively scheduled for late ’22.

NASA will be an anchor customer for the mission but Masten intends to sign up others. “There is a tremendous amount of interest,” he said, including from both the public and private sector, although he didn’t mention any specific potential customers.

Mahoney said the level of customer interest soared after Masten won the CLPS award and had a firm schedule for the mission. “Once the CLPS award was made and we crossed from speculative to having a schedule, the tenor and tone of our conversations have changed dramatically.”

The limiting factor for the lander mission has not been the amount of mass available for payloads, he said, but instead positions on the lander that have views of the surface desired by payloads. “There’s a game of positioning among the various instruments so that they can get the view angles that they need and not interfere,” he said.

However, he said the company isn’t considering major changes in the lander’s design to accommodate payloads. “The design principle is the ‘pickup truck’ that can haul a bunch of different things,” he said. “We’re trying to escape the completely unique, bespoke system that does one job and one mission really well.”

I guarantee that at least one university student-built payload will end up on the lander.

Skylab astronaut Gerry Carr passes away at 88

9:22 am

R.I.P. Gerry Carr, the commander of the last and longest Skylab mission in the 1970s, has passed away at 88.

Carr’s first and only spaceflight was as the commander of Skylab 4 (also referred to as SL-4 or “Skylab 3” as appeared on the crew’s mission patch). The third of three crewed stays of increasing duration aboard the orbital workshop, Carr and his Skylab 4 crewmates, Ed Gibson and William “Bill” Pogue, set what was then a record spending 84 days in space.

“We proved, I think, just absolutely, positively that the human being can live in weightless environment for an extended period of time,” Carr said during a NASA oral history interview in October 2000. “But medically, we gathered the data that I think gave the Russians and other people the understanding and the courage to say, ‘Okay, we can stay up for longer periods of time.'”

The obituary at the link includes Carr’s lifelong effort to explain that the crew never “mutinied,” as the press has tried to say for decades. Instead, they spent days and repeated long communications with mission control trying to get it to understand that the crew was being overworked because NASA was micro-managing their workload from the ground. They finally made mission control recognize this, after a long public conversation. Sadly, NASA had to relearn this lesson again in the 1990s during its first long missions on the Russian Mir space station (See chapters 3 and 12 in Leaving Earth).
