Axiom gets NASA approval to fly second commercial manned mission to ISS

9:02 am

Capitalism in space: NASA and Axiom have worked out their contract to allow Axiom to fly its second commercial manned mission to ISS, now scheduled for sometime in the spring of 2023.

Through the mission specific order, Axiom is obtaining from NASA services such as crew supplies, cargo delivery to space, storage, and other in-orbit resources for daily use. The order also accommodates up to an additional contingency week aboard the space station. This mission is subject to NASA’s updated pricing policy for private astronaut missions, which reflects the full value of services the agency is providing to Axiom that are above space station baseline capabilities.

The order also identifies capabilities NASA will obtain from Axiom, including the return of scientific samples that must be kept cold in transit back to Earth, the return of a Nitrogen/Oxygen Recharge System (NORS) tank, the capability for last-minute return of two cargo transfer bags, and up to 10 hours of the private astronaut mission commander’s time during the docked mission to complete NASA science or perform tasks for NASA.

The flight, dubbed Ax-2, will carry four Axiom passengers, three of whom will be paying passengers. It will be launched by SpaceX on its Falcon 9 rocket, carrying one of SpaceX’s four reusable manned Dragon capsules.

NASA awards SpaceX new $1.4 billion contract to launch its astronauts

8:56 am

Capitalism in space: NASA yesterday awarded SpaceX a new $1.4 billion contract to buy five more passenger flights to ISS, using SpaceX’s Falcon 9 rocket and Dragon manned capsules.

This follows a similar contract extension in February that awarded SpaceX three more NASA passenger flights.

For Boeing, this contract award must hurt. If its Starliner manned capsule wasn’t years behind schedule, with numerous engineering errors slowing development, some of the cash from these two new SpaceX contracts would have certainly gone to Boeing. Instead, the company has had to spend more than $400 million of its own money trying to get Starliner fixed and operational.

Cost overruns at Lockheed Martin threaten smallsat Lunar Trailblazer orbiter

8:56 am

NASA is now doing a review to decide if it will kill a smallsat lunar orbiter project, dubbed Lunar Trailblazer, due to cost overruns at Lockheed Martin.

Bethany Ehlmann, principal investigator for Lunar Trailblazer at Caltech, said in a presentation at LEAG Aug. 24 that Lockheed Martin, the spacecraft subcontractor, notified NASA of “recent and projected future overruns” on the project in June. Neither Ehlmann, NASA nor Lockheed Martin quantified those overruns.

“As we brought this mission from paper to life, the engineering and design efforts exceeded our original estimate,” Lockheed Martin said in a statement to SpaceNews Aug. 25. “Our Lockheed Martin team continues to implement cutting edge digital production tools and seek out operational efficiencies to minimize any extra cost incurred over Lunar Trailblazer’s development.”

The wording in this Lockheed Martin statement is meaningless blather, with no specific details. The bottom line however is this: Lunar Trailblazer was meant to demonstrate that it was possible to build a small low-cost science probe, in this case a lunar orbiter, and do it for no more than $55 million. Apparently, Lockheed Martin didn’t take that objective seriously. Instead, it thought it could do what it has done for decades — as have all the old big space contractors — pay no attention to cost, go overbudget, and then have NASA pick up the slack. It appears NASA might not do it this time.

Starliner manned launch delayed until 2023

8:42 am

NASA and Boeing yesterday announced that the first manned flight of a Starliner capsule has been delayed again, and will not occur before February 2023, at the earliest.

This delay is in order to fix the various thruster problems that occurred in the second unmanned demo flight in May 2021, dubbed OFT-2.

Nappi said some “debris-related conditions” likely caused those thrusters to shut down, but later noted that is their best estimate since the OMAC thrusters are in a service module that burns up on reentry and is not recovered. “We do not know where the debris may have come from,” he said. “The bottom line is that it looks to be the leading root cause, and we’ve eliminated that by looking at the CFT vehicle and making sure that there’s absolutely no debris in the system.”

Several reaction control thrusters also shut down during the mission, which Nappi said was likely due to low inlet pressures and can be addressed with a “tweak in timing and tolerances” in software. High pressures in a thermal control loop noticed in the mission were linked to filters that engineers determined are not needed and can be removed. A guidance system on the spacecraft called VESTA worked well but generated more data than the flight software could handle, requiring changes to the software. [emphasis mine]

The highlighted words indicate once again that there are quality control problems at Boeing. For any “debris” to get into the thrusters without notice means someone at some point wasn’t doing things right.

SpaceX and Boeing got contracts to fly humans on their commercial capsules at the same time, in 2014. SpaceX began those flights in 2020, about three years behind schedule, mostly due to NASA-imposed delays. Boeing has still not flown, with almost all its delays resulting from company failures, almost all of which were uncovered during the two unmanned demo flights in 2019 and 2022.

Hopefully, the company will finally get the last kinks from the system before next year’s flight. In the meantime its inability to get this job done on time has meant it has lost a lot of commercial business, all of which went to SpaceX.

NASA describes Starship’s first unmanned test lunar landing

9:28 am

In a briefing focused on the science that could be placed on the mission, a NASA official yesterday provided a status update of SpaceX’s first unmanned test flight by Starship to the Moon.

First, the official revealed that NASA is only requiring SpaceX to demonstrate a successful landing. Take-off will not be required. Also,

Starship is not designed to fly directly to the Moon like NASA’s Space Launch System, however. Instead, the first stage puts it only in Earth orbit. To go further, it must fill up with propellant at a yet-to-be-built orbiting fuel depot. Other Starships are needed to deliver propellant to the depot.

Watson-Morgan described the Concept of Operations for Starship’s Artemis III mission, starting with launch of the fuel depot, then a number of “propellant aggregation” launches to fill up the depot, then launch of the Starship that will go to Moon.

Previously SpaceX suggested that the ship would be directly refueled by subsequent Starships, with no middle-man fueling depot. It could be either engineering had made the depot necessary, or NASA politics have insisted upon it.

Finally, the talk outlined the elevator SpaceX is developing to lower the astronauts and equipment to the ground from Starship’s top.

NASA again approves design concept for Orbital Reef commercial space station

10:53 am

Proposed Orbital Reef space station

Capitalism in space: Sierra Space announced today that NASA has completed, apparently for the second time, the design review for the Orbital Reef space station that the company wants to build in partnership with Blue Origin and others, thus allowing the actual design of the station to begin.

This press release announcement, on August 22, 2022, is a bit puzzling, as Sierra Space made almost the exact same announcement in April 2022. What, did NASA have to do this twice? Did issues come up after the first approval? Was the agency reviewing different things?

Regardless, NASA as usual is slowing things down considerably. Sierra Space and Blue Origin, the primary partners in this private space station project, first announced it in October 2021. It took the government almost a year to simply approve the basic concept so that the design phase could finally begin. At this pace it will be 2090 before the station is launched.

NASA lists 13 candidate landing sites for Artemis-3 manned mission

Candidate landing sites for Artemis-3
Click for original image.

NASA yesterday revealed its first preliminary list of thirteen candidate landing sites for the Artemis-3 manned mission, the first manned mission the agency wants to send to the Moon in 2026.

The image to the right, reduced, enhanced, and annotated by me to post here, shows these thirteen zones in blue. I have added the red dot to mark what I understand to be the planned landing zone of Viper, an unmanned rover that NASA hopes to launch by ’23 at the latest. From the press release:

The team identified regions that can fulfill the moonwalk objective by ensuring proximity to permanently shadowed regions, and also factored in other lighting conditions. All 13 regions contain sites that provide continuous access to sunlight throughout a 6.5-day period – the planned duration of the Artemis III surface mission. Access to sunlight is critical for a long-term stay at the Moon because it provides a power source and minimizes temperature variations.

Note that this mission will land a Starship with crew at this South Pole region. That spacecraft’s large payload capacity likely means that it could conceivably leave behind supplementary supplies for a follow-up next mission, and thus speed up development of the first lunar base.

Astrobotic makes bid to buy assets of bankrupt Masten

9:02 am

Capitalism in space: Astrobotic, a startup focused on building lunar and planetary unmanned landers, has now made a formal bid to buy the remaining assets of Masten Space Systems, which had also been a startup focused on planetary missions but recently went bankrupt.

In a filing with the U.S. Bankruptcy Court for Delaware Aug. 14, Masten said it received a “stalking horse” bid of $4.2 million for Masten’s assets, including a SpaceX launch credit worth $14 million, from Astrobotic. The agreement, in effect, sets a minimum price for the sale of those assets but does not prevent Masten from seeking higher bids through an auction process that runs through early September.

The agreement appears to supersede an earlier agreement between Masten and a third lunar lander company, Intuitive Machines, included in Masten’s Chapter 11 filing July 28. That agreement covered the SpaceX launch credits alone and Masten did not disclose the value of it in its original filing.

Masten’s long term specialty has been vertical take-off and landing, something it has successfully done for the last several years on suborbital flights. This technology would be of great value to both Astrobotic and Intuitive Machines in developing their own first lunar landers.

SLS arrives at launchpad

8:44 am

The Space Launch System rocket (SLS) that will fly on NASA’s first test launch of this rocket on August 29, 2022 has finally arrived at its launchpad, seven years late and about $20 billion overbudget.

In the coming days, engineers and technicians will configure systems at the pad for launch, which is currently targeted for no earlier than Aug. 29 at 8:33 a.m. (two hour launch window). Teams have worked to refine operations and procedures and have incorporated lessons learned from the wet dress rehearsal test campaign and have updated the launch timeline accordingly.

The rollout from the Vehicle Assembly Building took ten hours.

NASA imposes new rules for any private launches to ISS

11:08 am

NASA has added several new rules for any private launches to ISS, now requiring that each flight include at least one experienced former NASA astronaut.

From the actual procurement notice:

NASA is also in the process of finalizing details associated with a new requirement that upcoming private astronaut missions include a former flown NASA (U.S.) government astronaut as the mission commander. A former NASA astronaut provides experienced guidance for the private astronauts during pre-flight preparation through mission execution. Based on their past on-orbit and NASA experience, the PAM commander provides a link between the resident ISS expedition crew and the private astronauts and reduces risk to ISS operations and PAM/ISS safety. Specific details of the requirement will be documented in future solicitations, as well as in updated documentation and in the solicitation technical library.

The new rules also require the companies to submit their research plans twelve months before launch, as well as reserve a longer time for the private passengers to adapt to weightlessness on the station before initiating that work.

The changes appear to make sense, based on the experience of the first passenger flight of Axiom sent up to ISS earlier this year. However, their existence will likely encourage the arrival of the private space stations in order to break free from NASA’s rules.

NASA is apparently withdrawing its permit for Starship launches in Florida

10:43 am

We’re here to help you: In requesting public input into SpaceX’s plans to expand operations in Florida to accommodate launches of its Starship/Superheavy rocket, NASA is apparently withdrawing the permit it issued in 2019, allowing for such launches.

While a Final Environmental Assessment for Starship was issued in September 2019, NASA said that communication with SpaceX will be ongoing prior to a future first flight from Florida.

“NASA will review the risks to the area and programs at KSC [Kennedy Space Center] prior to any hazardous work,” Bob Holl told Spectrum News in a statement. “NASA will be involved in the lead-up of activities prior to the first loading and any static fire events of Starship and coordinate impacts across the spaceport.” Holl serves as the chief of the Spaceport Management and Integration Division in the Spaceport Integration and Services Directorate at KSC.

It appears NASA and the federal bureaucracy have decided that a new environmental assessment is necessary for SpaceX’s proposed new operation in Florida. After a 30-day period for public input, ending on July 29th, NASA will issue a new draft environmental assessment by September, which will then be subject to another public comment period. Then, the agency will issue a final decision in November, either declaring the new work causes no further impact or that a new environmental impact statement is required.

If the latter, expect Starship launches at Kennedy to be delayed several years.

This action continues the increased regulatory oversight on new space activities being imposed since the arrival of the Biden administration. The federal government is now apparently trying to set a new policy whereby any new work by a private company on or even near federal land will require its full approval, and even if given that approval will carry with it strict and endless governmental demands, all designed to slow things down.

The political timing of this new action however is significant, since this decision will occur after the November midterms. If control of Congress shifts significantly into Republican hands, as expected, the Biden administration’s new heavy-handed regulatory approach might face some pushback.

NASA/ESA revise plan to recover Perseverance core samples from Mars

8:52 am

NASA and ESA yesterday announced that the agencies have revised their plan to recover Perseverance core samples from Mars, dropping the launch of a rover to pick up the samples.

Instead, they have decided to use Perseverance to bring the samples to the return vehicle, which will also carry two small helicopters.

In 2030, if all goes as planned, the NASA lander will touch down near where Perseverance is working. The rover will drive over to the lander, and an ESA-built robot arm will extract the tubes one by one and place them inside a spherical container the size of a basketball. In early 2031, a rocket on the lander will loft the container into Mars orbit, where a return craft built by ESA will snare it, enclose it in several layers of shielding for safety, and then head for home. In 2033, a saucer-shaped descent pod will carry the samples down to the Utah desert.

If Perseverance gets into difficulties during its 9-year wait for company, controllers can instruct it to drop its cargo of sample tubes onto the ground, creating a second depot. If that happens, the helicopters come into play: they can fly up to 700 meters, land next to a sample tube—each weighs up to 150 grams—and, with wheels on the bottom their feet, roll over the tube and pick it up with a grabber. On returning to the lander, they will drop the tubes on the ground for the arm to pick up.

The change means that the rover the United Kingdom was planning to build will either be abandoned, or repurposed as a lunar rover.

UAE names astronaut to fly on six month commercial ISS mission, purchased from Axiom

9:15 am

Sultan Al Neyadi in training
Sultan Al Neyadi in training

Capitalism in space: The United Arab Emirates (UAE) yesterday announced that 41-year-old Sultan Al Neyadi will fly on six month ISS mission, launching in the spring of 2023. purchased from Axiom.

The UAE purchased a seat on the Falcon 9 rocket from Axiom Space, a space infrastructure development company in Houston. This is the Falcon 9 seat that Axiom Space was given by Nasa after the company gave up its Russian Soyuz rocket seat for American astronaut Mark Vande Hei in 2021.

MBRSC did not disclose how much they paid Axiom for the seat, but the agreement includes transport to and from the space station; comprehensive mission support; all necessary training and preparation for launch; flight operations, landing and crew rescue services.

The deal behind this seat is very complex. Essentially, Axiom paid for the seat of Mark Vande Hei’s flight on a Soyuz capsule from 2021 to 2022 (because NASA had no authorized funds to purchase that seat), and got a later seat on a Dragon for an Axiom commercial customer. It then signed a deal with the UAE for Al Neyedi’s flight in late April.

The result is the first long term commercial mission to space.

Al Neyadi has been in training for four years, and acted as the back up astronaut to the first UAE manned flight to ISS, purchased from the Russians in 2019.

NASA’s safety panel questions NASA commitment to commercial space stations

10:18 am

We’re here to help you! Not surprisingly, members of NASA’s safety panel have once again expressed doubts about NASA’s ongoing effort to encourage a thriving private, competitive, and efficient commercial space industry, this time questioning the transition from NASA’s government-built space station, ISS, to privately-built and owned space stations, four of which are presently under development.

At a July 21 meeting of the Aerospace Safety Advisory Panel, members said they were concerned that commercial stations whose development is being supported by NASA were unlikely to be ready in time before the ISS is retired at the end of the decade, and that those efforts suffered from insufficient budgets.

Those plans, called Commercial Leo Earth Orbit (LEO) Destinations by NASA, “are on a precarious trajectory to realization on a schedule and within the projected resources needed to maintain a NASA LEO presence,” said Patricia Sanders, chair of the panel. “This is an area of concern for us.”

The panelists also questioned how quickly the stations would be man-rated (claiming NASA was not allocating enough time to do so) as well as whether NASA had enough work for four stations.

For the past decade this safety panel has consistently shown itself to be hostile to the new commercial space companies. It has never seen any safety issues or scheduling problems with NASA’s big SLS rocket. Nor did it notice Boeing’s significant software and valve problems on Starliner. Yet somehow, the work of SpaceX was dangerous (when it was not), and now these new stations, most of which are being built by new space companies, are equally unfit for use.

It is time to shut down this panel. Or at a minimum fire its present members and bring in new blood more willing to look at the entire space industry with a more objective eye.

Draper wins NASA contract to put a lander on the Moon’s far side

9:28 am

Capitalism in space: NASA yesterday awarded a $73 million contract to the space company Draper to place a lander on the Moon’s far side by 2025.

The lander, called SERIES-2 by Draper, will deliver to Schrödinger Basin three experiments to collect seismic data, measure the heat flow and electrical conductivity of the lunar subsurface and measure electromagnetic phenomena created by the interaction of the solar wind and plasma with the lunar surface.

The mission is the eighth NASA has awarded to date as part of CLPS, but the first to go to the lunar farside. The only mission by any country to land on the far side of the moon is China’s Chang’e-4 mission, which successfully landed in Von Kármán Crater in January 2019 and deployed the Yutu 2 rover that remains operational today.

With this award, there are presently five American companies with contracts to put landers on the Moon, Intuitive Machines, Astrobotic, Firefly, and Masten. Masten however shut down operations recently. This new contract to Draper for almost the exact same amount that had been awarded to Masten appears to replace Masten in the program.

NASA sets tentative launch date for SLS

9:46 am

NASA yesterday announced that it is targeting August 29, 2022 for the first unmanned launch of its SLS rocket.

NASA is tentatively targeting Aug. 29 for the long-awaited maiden flight of the agency’s huge Space Launch System moon rocket, officials said Wednesday. But they cautioned major challenges remain for the oft-delayed rocket and an official date will not be set until later.

As it stands, the launch processing schedule is extremely tight and depends on successful checkout of a repaired hydrogen line fitting, good results from end-to-end pre-flight checks of the rocket’s myriad other systems and getting everything done in time to haul it back out to the launch pad by around Aug. 18.

If any delays occur, this launch window extends until September 6th. If they can’t make that date, the next launch window opens on September 19th.

The mission, to send the Orion capsule around the Moon and back, would last 42 days and if launched as planned would return October 10th.

The announcement also slipped in this tidbit:

If the initial test flight goes well, NASA plans to launch four astronauts atop the second SLS rocket for an around-the-moon shakedown flight in 2024 — Artemis 2 — before sending the first woman and the first person of color to a landing near the moon’s south pole in 2025 or 2026 as part of the Artemis 3 mission. [emphasis mine]

This I think is the first time NASA officials have hinted that the launch might be delayed to ’26. It is no surprise, but as they have always done with SLS, they give these hints softly, prepping the press so that it doesn’t make news.

As for the disgraceful unseemly focus on race and sex, it appears that NASA is now an apartheid state. The make-up of missions will no longer be determined by skill and experience, but by ethnic considerations, with favoritism always given to minorities or women.

The May micrometeoroid impact on Webb’s mirror

9:37 am

Figure 3 from report

In a detailed report [pdf] of Webb’s overall excellent operational status following its in-space commissioning, the science team also included an analysis of the May 2022 micrometeoriod impact on one segment of Webb’s mirror.

The image to the right, taken from figure 3 of the report, shows the remaining alignment error of Webb’s entire mirror, after alignment. Except for that one bright spot in the segment to the lower right, all of the segments show excellent alignment, well within the range predicted before launch. The bright spot however is from the impact, and suggests that one mirror segment is significantly damaged. From the report:

The micrometeoroid which hit segment C3 in the period 22—24 May 2022 UT caused significant uncorrectable change in the overall figure of that segment. However, the effect was small at the full telescope level because only a small portion of the telescope area was affected. After two subsequent realignment steps, the telescope was aligned to a minimum of 59 nm rms, which is about 5-10 nm rms above the previous best wavefront error rms values 7 . It should be noted that the drifts and stability levels of the telescope mean that science observations will typically see telescope contribution between 60 nm rms (minimum) and 80 nm rms (where WF control will typically be performed). Further, the telescope WFE combines with the science instrument WFE to yield total observatory levels in the range 70-130 nm (see Table 2), so the slight increase to telescope WFE from this strike has a relatively smaller effect on total observatory WFE.

In plain English, the impact while damaging has not seriously reduced the telescope’s predicted capabilities.

However, to be hit with this size impact so soon after launch is very worrisome, especially because Webb’s mirror is not housed in any protective tube like Hubble or most telescopes. From the report:

It is not yet clear whether the May 2022 hit to segment C3 was a rare event (i.e. an unlucky early strike by a high kinetic energy micrometeoroid that statistically might occur only once in several years), or whether the telescope may be more susceptible to damage by micrometeoroids than pre-launch modeling predicted.

The science team is presently trying to anticipate what might happen if the impact rate turns out to be much higher than expected, and what can be done to mitigate the degradation of the mirror should more impacts occur.

NASA delays launch of its VIPER lunar rover to over concerns about commercial lander

8:58 am

VIPER's planned route on the Moon
VIPER’s planned route at the Moon’s south pole

In order to do more engineering tests of Astrobotic’s Griffin lunar lander, NASA has now delayed the launch of its VIPER lunar rover from November 2023 to November 2024.

NASA’s decision to pursue a 2024 delivery date results from the agency’s request to Astrobotic for additional ground testing of the company’s Griffin lunar lander, which will deliver VIPER to the lunar surface through CLPS. The additional tests aim to reduce the overall risk to VIPER’s delivery to the Moon. To complete the additional NASA-mandated tests of the Griffin lunar lander, an additional $67.8 million has been added to Astrobotic’s CLPS contract, which now totals $320.4 million.

Though the press release makes no mention of it, the launch of Astrobotic’s Griffin lander is partly dependent on the launch of Astrobotic’s first and smaller lunar lander, Peregrine, which was originally supposed to fly on the inaugural flight of ULA’s new Vulcan rocket, in 2021. That rocket’s first flight however has been delayed repeatedly because of delays by Blue Origin in completing development of the BE-4 rocket engine, to be used in Vulcan’s first stage. It is presently scheduled for early 2023, but that date remains tentative. This new delay of Griffin could be to make sure Peregrine flies first.

Regardless, this new budget increase means that the budget for Griffin has experienced a 62% cost overrun from its original $199 million number. This large increase in what is supposed to be a fixed price contract suggests that Astrobotic has been having some problems unstated by NASA, despite an inspector general report [pdf] that said all was going reasonably well.

Masten lays off staff, apparently shuts down

9:02 am

Capitalism in space: The small lunar lander company Masten Space Systems, which for years has worked to develop vertical rocket landing technology and has a $75.9 million contract with NASA to put a rover on the Moon, has apparently furloughed its staff and shut down operations.

The XL-1 lander was originally scheduled to launch in December 2022 bound for a landing at the moon’s south pole. In June 2021, Masten announced an 11-month launch delay to November 2023. The company said the delay was caused by industry-wide supply chain disruptions and the effects of the ongoing COVID-19 pandemic.

CLPS partners are expected to supplement NASA mission funding by carrying payloads for other parties. The source who requested anonymity said that is where Masten’s mission ran into problems. “We ran out of money after grossly underbidding. The estimate was $105 million but I was told that we had found a 30 million dollar private customer who wanted to fly with us,” the source said.

However, that customer later pulled out the venture. Subsequent attempts to fill the gap failed, the source added.

Masten is one of four companies with similar NASA lunar lander contracts. The others, Astrobotic, Firefly, and Intuitive Machines, all have scheduled missions planned, all of which however have been delayed for a variety of reasons.

Rogozin removed as Roscosmos’ head

8:52 am

Dmitry Rogozin, the head of Russia’s Roscosmos space corporation which controls the country’s entire aerospace industry, was fired yesterday and replaced by another former deputy prime minister, Yuri Borisov.

Don’t think Rogozin is out of favor with Putin however. Instead, it appears Putin wants his bull-headedness for running one of the regions Russia has conquered in the eastern Ukraine.

Following its tumultuous tenure as the head of Roskosmos, Rogozin was expected to move to the presidential administration and, possibly, lead it or “curate” the Russian occupation of the Eastern Ukraine, the independent Meduza publication reported.

I wonder if Rogozin’s removal is connected in any way with the ongoing negotiations between NASA and Russia’s foreign ministry for the barter agreement to allow the two to fly each other’s astronauts on each other’s capsules.

That agreement has been in negotiations and reviews for months by the two agencies as well as the U.S. State Department and Russian Foreign Ministry. NASA has long advocated for the agreement to enable what it calls “mixed crews” or “integrated crews” on spacecraft. That would ensure at least one NASA astronaut and one Roscosmos cosmonaut would be on the station should either Soyuz or commercial crew vehicles be unavailable for an extended period.

Rogozin’s bellicose manner has I think made those negotiations difficult. Putin might have decided, especially with the break up of its space partnership with Europe, to tone things down. Moreover, he might have realized that Rogozin’s contentious manner might be better put trying to take control of occupied Ukrainian territory.

Southern Ring Nebula, as taken by Webb
Click for full image.

As planned, NASA this morning released four new science images from the James Webb Space Telescope, in addition to the deep field image released yesterday.

All are spectacular, with each producing new information not previously observed. To see the Stephen’s Quintet image go here. For the exoplanet data, showing the presence of water in its atmosphere, go here. For the Carina nebula image, go here.

The image to the right, reduced to post here, shows the Southern Ring Nebula as taken by two Webb cameras in different infrared wavelengths. From the press release:

Two stars, which are locked in a tight orbit, shape the local landscape. Webb’s infrared images feature new details in this complex system. The stars – and their layers of light – are prominent in the image from Webb’s Near-Infrared Camera (NIRCam) [at the top], while the image from Webb’s Mid-Infrared Instrument (MIRI) on the [bottom] shows for the first time that the second star is surrounded by dust. The brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.

In the meantime, the brighter star influences the nebula’s appearance. As the pair continues to orbit one another, they “stir the pot” of gas and dust, causing asymmetrical patterns.

Because this is an infrared image, the colors are not natural, but were assigned based on the slightly different infrared wavelengths produced by the object’s different features. From the image’s webpage:

Several filters were used to sample narrow and broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter.

Eventually astronomers will use Webb to look at many astronomical objects that Hubble has been observing for the past thirty years, adding a high resolution infrared view that will add to Hubble’s views.

First science image released from Webb

3:40 pm

Webb's first deep field image
Click for original image.

The first science image from the James Webb Space Telescope has now been unveiled.

That image is to the right, reduced to post here. From the press release:

Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.

The smeared concentric arrangement of many reddish objects surrounding the picture’s center strongly suggests we are seeing distortion by the gravity of this galaxy cluster.

While nothing in this image appears at first glance to be different than many earlier Hubble images, it looks at objects in the infrared that are much farther away than anything ever seen before, farther than Hubble in the optical could see. To understand the new discoveries hidden in such an image will likely take several years of further research. For example, before astronomers can understand what this image shows they need to determine the red shift of each galaxy, thus roughly determining its distance and the overall 3D structure of the objects visible. Moreover, the consequences of the gravitational lensing must be unpacked.

The White House briefing itself was somewhat embarrassing to watch, as Vice President Kamala Harris, President Joe Biden, and NASA administrator Bill Nelson all struggled to explain what this image shows, and failed miserably. Moreover, the briefing had technical problems, started very late, and it appeared that Bill Nelson especially had no idea what he was looking at. The briefing also ended very abruptly when it shifted to reporters’ questions.

Engineers lose contact with CAPSTONE on its way to Moon

2:24 pm

Shortly after the spacecraft was successfully deployed from its Proton upper stage on yesterday, engineers lost contact with the spacecraft as it headed towards the Moon.

“The spacecraft team currently is working to understand the cause and re-establish contact. The team has good trajectory data for the spacecraft based on the first full and second partial ground station pass with the Deep Space Network,” NASA spokesperson Sarah Frazier wrote in an emailed statement today (July 5).

“If needed, the mission has enough fuel to delay the initial post-separation trajectory correction maneuver for several days,” Frazier added. “Additional updates will be provided as soon as possible.”

The spacecraft will not arrive in lunar orbit until November, but along the way it needs to do a number of course corrections. Thus, there is some time pressure to reestablishing communications. That task now falls with the private company Advanced Space, which won a contract to operate the spacecraft for NASA.

UPDATE: More details are provided by the operators of the spacecraft, Advanced Space press, here. Though they canceled a course correction burn today, they apparently have plenty of time to do it, since the probe is already on a course to reach lunar orbit. The burn was simply intended to increase the accuracy of the trajectory.

Food fight! China denies NASA chief’s charge that it wants to dominate space

9:16 am

On July 2, 2022, in an interview for a German news outlet, NASA administrator described in somewhat overbroad terms the long range goals of the Chinese space program.

“We must be very concerned that China is landing on the moon and saying: ‘It’s ours now and you stay out,’” Mr. Nelson said in an interview published Saturday in the German newspaper Bild.

….China’s space program, at its heart, is a military space program, Mr. Nelson said. “China is good. But China is also good because they steal ideas and technology from others,” he said, according to Bild.

A China spokesman for its Foreign Ministry, Zhao Lijian, immediately slammed Nelson’s comments, adding some of his own overbroad accusations against the U.S.
