Virgin Orbit gets $9.5 million from UK space agency

9:03 am

The space agency of the United Kingdom yesterday awarded $9.5 million to the smallsat rocket company Virgin Orbit

ccording to the statement, the funds will be used “to develop launch operations support systems and manufacture them in the U.K.” in addition to conducting “mission planning, and to further ready the facility for satellite launches from Cornwall”.

This award is part of a larger funding package of $26 million (£20 million) from Cornwall Council and the Cornwall and Isles of Scilly Local Enterprise Partnership, while Virgin Orbit have also said they will contribute about $3.2 million (£2.5 million) to the Spaceport Cornwall project. The hope is that Cornwall could become a hub for European launches to space in the future.

Essentially this is an effort by the UK to bring Virgin Orbit’s launches to Cornwall spaceport. Why Virgin Orbit has got this money is puzzling however. Launched from a 747 which can take off from almost all airports, Virgin Orbit doesn’t necessarily need to launch from a spaceport. That fact is probably why the company got this “pay-off”, using somewhat more blunt words.

Sightseeing Central Butte on Mars

11:38 am

Central Butte in foothills of Mt Sharp

Overview showing perspective of panorama

Curiosity has now roved to the very foot of Central Butte, where it has been taking close-up and panorama images of the butte and its geological layers. The panorama above was created from three Curiosity navigation images taken on Sol 2577 (November 6, 2019), here, here, and here.

The overview on the right, based on Curiosity’s position about ten sols ago slightly farther from the butte, still indicates roughly with the yellow lines the area photographed in this panorama. The dotted red line indicates Curiosity’s initial planned route.

Following that route Curiosity will eventually climb up onto the plateau beyond this butte, approaching that higher terrain farther to the west. Once they do, however, they will no longer have access to the geological layers below the surface. Central Butte gives them a window into those layers, which is why they are going to spend some time at this location, first by taking a few sols looking at the butte at this point, then circling around to study its back side.

NASA rejects Blue Origin’s proposed SLS upper stage

9:21 am

After considering an alternative bid by Blue Origin to build a less expensive upper stage for NASA’s SLS rocket, replacing the stage that Boeing is building, NASA has decided to reject that bid and stick with Boeing.

NASA sets out three reasons for not opening the competition to Blue Origin. In the document, signed by various agency officials including the acting director for human spaceflight, Ken Bowersox, NASA says Blue Origin’s “alternate” stage cannot fly 10 tons of cargo along with the Orion spacecraft.

Moreover, NASA says, the total height of the SLS rocket’s core stage with Blue Origin’s upper stage exceeds the height of the Vertical Assembly Building’s door, resulting in “modifications to the VAB building height and substantial cost and schedule delays.” Finally, the agency says the BE-3U engine’s higher stage thrust would result in an increase to the end-of-life acceleration of the Orion spacecraft and a significant impact to the Orion solar array design.

The article notes that there were also significant political reasons as well that pushed NASA to favor Boeing.

The article also states that SLS’s cost per launch will be about $2 billion. Though I think that number is probably low because it does not include any of the $25 billion spent for development, it does compare badly with SpaceX’s Falcon Heavy, which costs about $100 million per launch.

NASA to fly more year-plus missions to ISS

9:03 am

Leaving Earth: In an effort to shift the research focus on ISS toward learning how to do interplanetary missions, NASA wants to fly more year-plus missions to the station.

Crewmembers usually spend about six months aboard the ISS before coming back down to Earth. But that’s far shorter than a Mars mission would be; the trip to the Red Planet takes eight to nine months one way with current propulsion technology. So, NASA wants more data about the effects of long-duration spaceflight on the physiological and psychological health of astronauts. (The ISS isn’t a perfect Mars analog in this respect, of course; it resides within Earth’s protective magnetosphere and is therefore exposed to less-damaging radiation than a Mars-bound craft would be.)

To date, the agency has launched just one yearlong ISS mission, sending Scott Kelly to live on the orbiting lab from March 2015 to March 2016. Russian cosmonaut Mikhail Korniyenko took part in this flight as well, spending 342 days in space, just like Kelly. NASA has also extended two other astronauts’ ISS stays into the “Mars transit” range: Peggy Whitson racked up 289 days of continuous flight in 2016 and 2017, and Christina Koch, who arrived on the orbiting lab in March, is now scheduled to come down in February 2020.

But these three data points aren’t enough, said [Julie Robinson, NASA’s chief scientist for the ISS Program],. “What we’re saying now is we want to really bump that up a notch and add 10 more subjects to that U.S. database,” she said.

The ISS Program has approved that plan, which NASA can start implementing once a private astronaut taxi is up and running, Robinson added.

NASA should have been doing this from the beginning, The Russians have always wanted to do longer missions, and have been frustrated by NASA’s resistance. That the agency is now pushing to focus ISS research on learning how to do interplanetary travel is wonderful news. It means that we will finally be using ISS properly.

Boeing proposes manned lunar lander that bypasses Gateway

8:47 am

Capitalism in space: Boeing today announced its bid to build a manned lunar lander for NASA’s Artemis program, with its lander launched to go directly to the Moon rather than stopping at the proposed Lunar Gateway lunar space station.

The company said its “Fewest Steps to the Moon” proposal, submitted for NASA’s Human Landing Services program, minimized the number of launches and other “mission critical events” needed to get astronauts to the surface of the moon. “Using the lift capability of NASA’s Space Launch System Block 1B, we have developed a ‘Fewest Steps to the Moon’ approach that minimizes mission complexity, while offering the safest and most direct path to the lunar surface,” Jim Chilton, senior vice president for space and launch at Boeing Defense, Space and Security, said in a company statement.

The two-stage launched would launch on the enhanced Block 1B version of the rocket, which uses the more powerful Exploration Upper Stage (EUS), and go into lunar orbit. It would either rendezvous with the lunar Gateway or directly with an Orion spacecraft, where astronauts would board it for a trip to the lunar surface. The lander is designed to be launched as a single unit, rather than in separate modules that would be aggregated at the Gateway. The lander also doesn’t require a separate transfer stage to maneuver from a near-rectilinear halo orbit to low lunar orbit, as some other designs have proposed.

This approach, the company said in a statement, reduces the number of mission critical events, such as launches and dockings, to as few as five. Alternative approaches, Boeing claims, require 11 or more such events. [emphasis mine]

Boeing is essentially proposing a plan that makes Gateway unnecessary, a bidding ploy that very well might work with the Trump administration, which has already reduced Gateway’s initial construction to speed up its attempt to get to the Moon by 2024.

More important, Boeing’s proposal makes it very clear how unnecessary Gateway is, and how that boondoggle actually slows down our effort to return to the Moon. This is great news, for several reasons. First it shows that Boeing, one of the old big contractors that historically has depended on government dollars, is now publicly stating that it is not in favor of Gateway. This in turn makes it more politically acceptable for politicians to take this position. Expect more public advocacy against building Gateway.

Second, it shows that Boeing is trying to sell SLS. It wants Congress to appropriate more launches, and by showing Congress a cheaper way to use it the company is hoping legislators will buy into their proposal. SLS might be an exceedingly expensive rocket, but Gateway only makes it worse. Boeing is showing the world that there is a better and cheaper way to do things.

This also suggests that Boeing is recognizing the competition coming from SpaceX and others that might kill SLS, and is now trying to make SLS more competitive. While I am not a fan of SLS, if this proposal indicates an effort by Boeing is finally to make SLS more efficient and affordable I can only celebrate. The rocket has capabilities that are unique, and if its cost can be reduced in any way that can only benefit the U.S. effort to compete in the exploration and settlement of the solar system.

TESS completes 1st survey of southern sky

1:19 pm

The TESS science team today released its first full panorama of the southern sky, revealing everything the space telescope has imaged since launch in one image.

The glow of the Milky Way — our galaxy seen edgewise — arcs across a sea of stars in a new mosaic of the southern sky produced from a year of observations by NASA’s Transiting Exoplanet Survey Satellite (TESS). Constructed from 208 TESS images taken during the mission’s first year of science operations, completed on July 18, the southern panorama reveals both the beauty of the cosmic landscape and the reach of TESS’s cameras. “Analysis of TESS data focuses on individual stars and planets one at a time, but I wanted to step back and highlight everything at once, really emphasizing the spectacular view TESS gives us of the entire sky,” said Ethan Kruse, a NASA Postdoctoral Program Fellow who assembled the mosaic at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Within this scene, TESS has discovered 29 exoplanets, or worlds beyond our solar system, and more than 1,000 candidate planets astronomers are now investigating.

A reduced version of this image wouldn’t show anyone its beauty or significance. I have embedded below the fold the short video at the link which shows it quite nicely. The video also summarized the mission quite well.

China uses Long March 3B to launch GPS-type satellite

9:04 am

China yesterday successfully launched another Beidou GPS-type satellite, using its Long March 3B rocket.

The leaders in the 2019 launch race:

22 China
17 Russia
10 SpaceX
6 Europe (Arianespace)
4 ULA
4 India

China has now tied the U.S. 22 each in the national rankings, surging in launches to come from behind in the last few weeks. This is not surprising, in that China tends to concentrate its launches in the fall.

Boeing & NASA declare pad abort test a success

8:44 am

According to the NASA press release for yesterday pad abort test of Boeing’s Starliner capsule, the test was a success even though one of three main parachutes did not deploy successfully.

A pitcharound maneuver rotated the spacecraft into position for landing as it neared its peak altitude of approximately 4,500 feet. Two of three Starliner’s main parachutes deployed just under half a minute into the test, and the service module separated from the crew module a few seconds later. Although designed with three parachutes, two opening successfully is acceptable for the test parameters and crew safety. After one minute, the heat shield was released and airbags inflated, and the Starliner eased to the ground beneath its parachutes.

All reports say that this parachute issue will not effect the December 17 planned launch of the first unmanned orbital flight to ISS.

I find NASA’s reaction to this anomaly fascinating. Previously the agency repeatedly made a very big deal about the slightest anomaly by both Boeing and SpaceX on any test or procedure. While the agency’s response to these problems could have been reasonably justified, the caution it sometimes exhibited, often causing significant delays that might have been avoidable, was somewhat disturbing, especially when contrasted with the agency’s willingness to accept far more serious issues in connection with SLS and Orion.

Now however, the agency has no problem with the failure of one parachute to deploy during this test. While I actually agree with this response, the contrast is interesting and suggests to me that politics and deadlines (with the Russian Soyuz contract running out) are finally exerting some influence over NASA’s safety people. I suspect it has been made clear to them that unless something really seriously goes wrong, as long as the tests would have resulted in living astronauts, the safety bureaucrats had better not stand in the way of progress.

If so, this is very good news. It means that, assuming nothing really goes wrong with the remaining tests, the first manned missions are finally going to occur next year, relatively early in the year.

Interstellar space, as seen by both Voyager spacecraft

11:36 am

Today a suite of new science papers were published outlining what scientists learned when Voyager 2 joined Voyager 1 in interstellar space last November.

The Sun’s heliosphere is like a ship sailing through interstellar space. Both the heliosphere and interstellar space are filled with plasma, a gas that has had some of its atoms stripped of their electrons. The plasma inside the heliosphere is hot and sparse, while the plasma in interstellar space is colder and denser. The space between stars also contains cosmic rays, or particles accelerated by exploding stars. Voyager 1 discovered that the heliosphere protects Earth and the other planets from more than 70% of that radiation.

The data also shows that Voyager 2, which exited the heliosphere somewhat perpendicular to its direction of travel, is still in the transitional zone between the heliosphere and interstellar space. Voyager 1 exited out the head of the heliosphere, so its transitional zone was compressed and shorter.

The real achievement of these results however is that they were obtainable at all. For both spacecraft to be functioning so well after forty years in space, and able to get their data back to Earth from distances more than 11 billion miles, is a true testament to the grand engineering that went into their design and construction.

They built well in the mid-twentieth century.

SpaceX successfully completes 13 parachute drop tests of Crew Dragon

8:43 am

Capitalism in space: SpaceX in two weeks has apparently completed a strong of thirteen successful parachute drop tests of its Crew Dragon capsule.

SpaceX says it successfully completed thirteen consecutive tests of Crew Dragon’s new Mk3 parachutes, all of which were completed in less than two weeks. This essentially blows Bridenstine’s expectations out of the water, as SpaceX has surpassed his predicted 10 tests and done so barely three weeks into the tentative 12-week window he set. SpaceX now has plenty of time to either continue testing Crew Dragon’s parachutes or refocus its efforts on other equally important qualification challenges.

Prior to those thirteen consecutive successes, SpaceX suffered two failures during single-parachute Mk3 testing. The first two development tests of the Mk 3 design used loads much higher than the parachutes would ever see in operation in an effort to better understand overall design margins and system performance. After a period of rapid iteration with parachute provider Airborne Systems, the faults responsible for those two stress-test failures were resolved and subsequent drop tests confirmed that Mk3’s suspension lines – the numerous lines connecting the parachute to Crew Dragon – are far stronger than those on Mk2.

Bridenstine had mentioned in a tweet that SpaceX was planning ten drop tests, so the company has now exceeded those plans.

Boeing completes Starliner pad abort test

8:32 am

Embedded below the fold is the video of today’s Starliner pad abort test, cued up to just before launch. While the capsule landed safely, it appears that one of it’s parachutes deploy improperly. If so, this probably means Boeing will not be able to launch the unmanned demo flight to ISS on December 17.

No one during the podcast mentioned this fact, so it could mean that they considered the landing a success regardless. It is even possible that they planned it with only two chutes. Or it could be the corporate culture at Boeing, similar to the culture in the Soviet Union, to avoid mentioning non-obvious problems to the public in order to make believe all is well. We will have to wait and see.

UPDATE: More information here on the failure of one chute:

Video of the test appeared to show all three chutes deploy, but only two remained attached to Starliner – a significant issue that will have to be investigated and evaluated.

Hat tip to reader Col. Beausabre for the link to the video.

China launches remote sensing satellite

8:32 pm

Using its Long March 4B rocket China today successfully launched a remote sensing Earth resources satellite.

They also once again tested grid fins on the first stage, comparable to the ones on SpaceX’s Falcon 9, for controlling the landing zone of that first stage.

The leaders in the 2019 launch race:

21 China
17 Russia
10 SpaceX
6 Europe (Arianespace)
4 ULA
4 India

The U.S. now leads China 22 to 21 in the national rankings..

Upcoming schedule of Boeing & SpaceX manned capsule tests

10:12 am

The next two months are going to be a busy time for both Boeing and SpaceX as they attempt to complete the last tests necessary to their respectively Starliner and Crew Dragon capsules before they each launch a manned mission to ISS.

Below is that schedule as of today:

November 4: Boeing will do a Starliner pad abort test, to be live streamed.
November 6: SpaceX will do a final static fire test of Crew Dragon’s SuperDraco abort engines.
November-December: SpaceX will do a series of parachute drop tests of Crew Dragon
December 17: Boeing will launch Starliner unmanned in a demo mission to ISS.
December (third week): SpaceX will complete a launch abort test of Crew Dragon

The article at the first link above provides a lot of detail about both companies’ abort tests.

Assuming these tests all go as planned, both companies will then have completed all engineering tests required prior to their first manned missions. As far as I can tell, the only thing standing in their way at that point will be filling out the voluminous paperwork that NASA is demanding from them.

Russia ships three more engines to U.S. for ULA’s rockets

9:50 am

Russia announced yesterday that it has delivered three more RD-180 engines to ULA for use in its Atlas 5 rocket.

The article notes that this contract, as well as the contract with Northrop Grumman to make RD-181 engines for the Antares rocket, both end in December 2019. While ULA has said it plans to replace the Russia engine with Blue Origin’s BE-4 engine (still under development), it is not clear what Northrop Grumman will do.

In both cases, Russia has delivered enough engines to cover launches for the next few years. This will give Blue Origin time to complete development of the BE-4. As for Antares, the lack of its Russian engine, combined with its inability to obtain any customers other than NASA, could spell the end of that rocket once Northrop Grumman has used up its engine stockpile.

Shelby delivers big bucks to SLS, Gateway

9:41 am

The boondoggle that never ends! The Senate has passed a 2020 budget that includes an increase of $1.2 billion for NASA’s Artemis program and Trump’s 2024 manned lunar landing proposal, almost all of which will go to Alabama, the home state of Senator Richard Shelby (R-Alabama).

In the Exploration section of the budget that does include the Moon mission, the big new rocket called the Space Launch System (SLS) would get nearly $2.6 billion in 2020, a $1.2 billion jump from this year. SLS is managed by the Marshall Space Flight Center in Huntsville.

The Orion crew capsule program would get $1.4 billion for continued development, the planned Lunar Gateway would get $500 million and lunar landers would get $744 million.

If the Democratically-controlled House ever decides to do anything but pursue sham impeachment charges against President Trump (such as approve a budget or deal with the Senate’s proposed commercial space legislation), it remains doubtful it will approve similar increases. During recent hearings on the budget, when the House was actually doing its real job, the Democrats were very hostile to funding Trump’s 2024 Moon proposal.

And even if the House should eventually go along, unlikely as that is, the money will not really get us closer to the Moon. The bulk of this cash is targeted to pay the salaries of NASA bureaucrats at Marshall, not actually build anything.

Meanwhile the second link above, “Cruz criticizes House for lack of action on commercial space legislation,” highlights the irresponsibility of the House under Democratic control.

Cruz and several other senators from both parties reintroduced the Space Frontier Act in March. The bill, favorably reported by the Senate Commerce Committee in April, calls for reforms of commercial launch and remote sensing regulations, which are already in progress, extends the authorization of the International Space Station through 2030 and elevates the Office of Space Commerce within the Commerce Department to the Bureau of Space Commerce, led by an assistant secretary.

The House, though, has not introduced a companion bill or related legislation, a lack of action that Cruz criticized. “It’s now been nearly a year since the Space Frontier Act has been on the House floor, and airlines, airline pilots and commercial space companies are no closer to getting greater certainty or having more of a voice on how our national airspace is managed than they were a year ago,” he said.

The Democrats might not agree with the language in this Senate bill, but they have an obligation to offer some alternative. Instead, they spend their time trying to overturn a legal election that they lost.

Turkey negotiating with Russia to train its future astronauts

9:23 am

Turkey might not have yet established its space program, nor have any announced intention of sending anyone into space, but it is presently negotiating with Russia to send any of its future astronauts to Russia for training.

Turkey has confirmed its intention to send astronauts to Russia for training, as follows from a report uploaded to the website of the Russian space corporation Roscosmos on Thursday following a working meeting between Roscosmos CEO Dmitry Rogozin and Turkey’s Ambassador to Russia Mehmet Samsar.

“The Turkish side confirmed its original plans for having its astronauts trained in the Star City,” the news release runs. “In the conversation topical issues concerning mutually beneficial cooperation in space were discussed. The two sides noted the great potential and importance of this theme in relations between the two countries,” the news release adds.

Earlier, the Roscosmos CEO said a Turkish astronaut might go to the International Space Station in 2021-2023.

Roscosmos right now is the only place in the world that has an established program for training astronauts, and it is clearly trying to make itself the go-to place for this service. This in turn gives Russia a big advantage in any worldwide competition for flying tourists or international governmental astronauts. If Turkey for example needs to choose between buying astronaut tickets on SpaceX or Roscosmos, it will lean toward Roscosmos because that was where its astronauts were trained.

Virgin Galactic stock drops 25% since IPO on Monday

9:14 am

Capitalism in space: While this article focuses more on jabs taken by the head of British Airways against Richard Branson and Virgin Galactic, it contains one tidbit of real note:

Shares in Virgin Galactic have fallen by more than a quarter since it went public at the start of the week, wiping more than $600m (£464m) off its value.

On Monday, the initial offering price for stock in Virgin Galactic was $12.93. At the moment it is trading in the mid-$9 dollar range, with the low earlier today of $9.09. Overall the stock lost about 25% of its value in a week, indicating properly that its value had been inflated by Branson and his partners in that initial offering.

But then, inflating the value of Virgin Galactic has been Richard Branson’s mode of operation since 2004 when he founded the company. I continue to wish the company success, but have become exceedingly skeptical about it.

And to change my mind the company is going to have to finally actually accomplish something, rather than make empty promises that never come true.

MarCO cubesats almost failed just before InSight landing

9:34 am

According to a report by one of its engineers, contact was lost with the two MarCo cubesats just prior to InSight’s landing on Mars, and was recovered just in time.

The team spent all day looking at the fault tree to fix the issue, Klesh recalled. “At 6:05 a.m. [California time] the next morning, MarCO-B shows up just on time,” apparently recovering automatically from an attitude-control issue, Klesh said. He proudly told mission managers at 6:30 a.m. that both cubesats were ready to go.

But then, “45 minutes later,” he said, “MarCO-A disappeared.”

At that point, it was too late to make any changes. JPL had already sent its last commands to InSight and MarCO through NASA’s Deep Space Network (DSN) of telescopes that communicate with spacecraft far out in the solar system. So the engineers could only watch and wait. “We didn’t know what was going to happen [during landing] in a few hours’ time,” Klesh said.

Luckily for the team, MarCO-A (and its twin) both popped into communications at 12:14 p.m. and succeeded in relaying data from the InSight touchdown, sending back valuable information about the dangerous entry, descent and landing phase to NASA engineers to plan for future missions.

They have traced the issue of MarCo-A’s disappearance to being blinded by the light from Mars, thus confusing its star tracker. That both spacecraft auto-recovered when contact with Earth was lost however is I think a fine testament to their design.

Update on Starship Mk1 assembly

9:22 am

Link here. It appears its launch pad has been assembled at Boca Chica and the spacecraft has been moved and placed on it.

It also appears that they are aiming for the first tests no earlier than November.

The newest videos at the link are worth a glance, though somewhat tedious as with each they view a worksite from a distance where not much appears to happen quickly. The last however shows the ship being moved and lifted and placed on the launch pad.

I cannot deny a certain skepticism when I look at this first iteration of Starship. The hull especially fills me with trepidation, since it is made up of many welded riveted together plates that do not create a smooth surface. I wonder how this surface will respond to returning from orbit at near orbital speeds.

UPDATE: I mistakenly referred to the plates initially as “riveted”. They are welded together, as correctly noted by one of my readers, and I have corrected the post accordingly.

Orion capsule has no room for Moon rocks

11:05 am

Good enough for government work! It appears that the Orion capsule that NASA and Lockheed Martin have been building since 2004 — for a total cost of a mere $18 billion — with the express purpose of sending American astronauts on missions to the Moon and beyond, has been designed without any capability for bringing lunar samples back to Earth.

The article at the link is mostly a dive into NASA’s make-believe plans about what will happen on the proposed 2024 lunar landing being pushed by Trump, a mission as yet unfunded by Congress and dependent on a NASA rocket, SLS, that has yet to launch and is years behind schedule. Buried however at the very end of article however was this bombshell:

One of the limitations on returning samples is the Orion spacecraft, which will carry astronauts back from lunar orbit to Earth. Chavers said the Orion spacecraft does not have any designated space for a box of sample rocks taken from the lunar surface. “We just don’t know what the capability will be,” Chavers said of bringing rocks back to Earth inside Orion.

I hadn’t read this article in detail because of its nature, essentially a NASA puff piece pushing the agency’s fantasies. Hat tip to reader Scott M. for pointing it out.

If this absurd design failure doesn’t illustrate the incompetence of our modern NASA and its big contractors, I don’t know what does. I cannot imagine how it is possible for anyone involved in this project to leave out this tiny detail. What point is there to built a spaceship for returning astronauts from planetary missions if you don’t include the capacity to return samples? None.

In fact, this omission is further proof that the goal of Artemis (SLS, Orion, Gateway) is merely to suck money from the taxpayer, without really accomplishing anything. It is also further evidence of my previous conclusion, that NASA’S entire Orion concept is a lie.

Webb telescope faces more schedule risks, engineering issues

8:29 am

Even as NASA touts the final assembly of the James Webb Space Telescope, its program director noted in a presentation that the telescope is still facing several engineering issues that could cause further launch delays.

They presently are targeting a March 2021 launch on an Ariane 5 rocket (ten years behind schedule). Their schedule cushion (the extra time built into their schedule in case they have problems) however has shrunk from nine months to only two. Worse, there remain several lingering unsolved engineering problems.

One such problem is with an electronics unit called a command telemetry processor that malfunctioned during environmental testing. Robinson said engineers had problems duplicating the problem to determine the root cause and plan to replace the unit, along with a traveling wave tube amplifier used in the spacecraft’s communications system that also failed during testing.

NASA has also been working with launch provider Arianespace about concerns that residual pressure within the payload fairing at the time of fairing separation could “over-stress” the sunshield membranes. Tests on recent Ariane 5 launches confirmed that there was a higher residual pressure than the sunshield was designed for. Vents in the fairing are being redesigned to address this, Robinson said, and will be tested on Ariane 5 launches in early 2020.

However, those smaller problems, along with bigger issues like fastener problems with the sunshield found during environmental testing last year, have eroded the margin built into the revised schedule for the mission.

Unmentioned in the article is the fact that Arianespace is planning to retire the Ariane 5 when its Ariane 6 starts launching next year. Right now they have agreed to maintain their Ariane 5 launch facilities through March 2021 to allow Webb’s launch, but further delays could cause significant problems, including fixing the fairing issue mentioned above. At a certain point Arianespace will no longer be willing to hold onto Ariane 5 for just this one launch.

Also unmentioned in the article is the status of Webb’s budget, which has grown from a proposed $500 million cost to almost $10 billion. I suspect that if they can meet their March 2021 launch date that total will not grow much. Any further delays however will once again cause it to balloon.

(I originally listed the proposed cost of Webb above as $1 billion, but that number is wrong. See the comments below).

Jupiter’s thunderheads

The cloud tops of Jupiter
Click for full image.

Using raw Juno images, citizen scientist Gerald Eichstädt has created the processed and color enhanced image to the right, cropped to post here. From the Juno press release:

This view from NASA’s Juno spacecraft captures colorful, intricate patterns in a jet stream region of Jupiter’s northern hemisphere known as “Jet N3.”

Jupiter’s cloud tops do not form a simple, flat surface. Data from Juno helped scientists discover that the swirling bands in the atmosphere extend deep into the planet, to a depth of about 1,900 miles (3,000 kilometers). At center right, a patch of bright, high-altitude “pop-up” clouds rises above the surrounding atmosphere.

Some of the darker areas are darker mostly because they are lower and therefore in shadow.

The raw image was taken on May 29, 2019 when Juno was about 6,000 miles away. Unfortunately, they do not provide a scale, but I suspect that the image is probably close to the size of the entire Earth.

Curiosity

For the overall context of Curiosity’s travels, see my March 2016 post, Pinpointing Curiosity’s location in Gale Crater.

I have not done any of my regular rover updates since May 30, 2019 because it was simpler to do individual updates for both Curiosity and Yutu-2, the only working rovers presently on other worlds. (If things had gone well, which they did not, we would have had two other lunar rovers in the past six months, one from Israel and one from India, but both crashed during landing.)

However, since Curiosity is finally on the move after spending several months at one location, where it drilled two holes in the clay unit (the material from one used in a wet cup experiment to look for organic life) it is time to update my readers on where Curiosity is and where it is heading.

The first image above and to the right is an annotated overview of Curiosity’s present position, moving south to a line of buttes which scientists have determined delineates the transition from the clay unit to a new geological layer they have dubbed the Greenheugh Pedimont. The yellow lines indicate the area seen in the panorama below, created from two photographs (here and here) taken by the rover’s navigation camera.

Starship manned lunar landings by 2022?

8:51 am

Capitalism in space: According to SpaceX’s CEO Gwynne Shotwell at a conference on October 25, the company is targeting the first unmanned cargo landing of Starship on the Moon by 2021, with manned missions shortly thereafter.

Shotwell, speaking at Baron Fund’s annual investment conference at the Metropolitan Opera House on Friday, gave an update on SpaceX’s goals for Starship. “We want Starship in orbit next year; we want to land it on the moon before 2022 with cargo and with people shortly thereafter,” Shotwell said.

However, much like Musk in his presentation last month, Shotwell hedged her estimate, saying that “every time I make a prediction about schedule I turn myself into a liar.”

If they even come close to doing this they will certainly make NASA’s SLS rocket look ridiculous. They began serious development of Starship in early 2019. Even if development takes twice as long as Shotwell’s prediction, they will be landing on the Moon in about six years, in 2025. SLS has been in development since 2004, and its total cost once launched is expected to be more than $25 billion, a cost that does not include an extra $1.6 billion NASA has said it needs to land on the Moon by 2024 and that Congress has so far refused to appropriate.

SpaceX meanwhile has raised $1.3 billion, from private sources, to build Starship.

Crew Dragon successfully tests SuperDraco engines

8:41 am

Capitalism in space: SpaceX’s Crew Dragon capsule, planned for a launch abort test in December, has successfully completed a set of static fire engine tests of two of its SuperDraco launch abort engines.

They next plan a static fire test of all eight engines, followed by that launch abort flight. If all goes well with both, the only thing blocking SpaceX from launching its first manned mission early in 2020 will be the paperwork NASA is demanding they fill out prior to flight.

InSight’s mole has popped out of its hole

8:35 am

InSight's mole, out of the ground
Click for full image.

In a setback for its renewed digging effort, the mole drill on InSight has apparently bounced out of its drilled hole during the most recent drilling, soon after engineers had increased the rate of hammer strokes.

The image to the right shows the mole, the white cylinder on the left, with the scoop of the robot arm mostly covering the hole in its effort to pin the mole in position.

“While digging this weekend the mole backed about halfway out of the ground,” the mission announced via a pair of tweets Oct. 27. “Preliminary assessment points to unexpected soil properties as the main reason.”

…The mission added that one possibility is soil is falling in front of the mole, filling the hole. “Team continues to look over the data and will have a plan in the next few days.”

Without question the alien and fluffy properties of the soil appears to be the problem. Based on how the mole is leaning, I wonder if the left wall of the hole began to widen and collapse, as had the rest of the hole during initial drilling, thus defeating the purpose of the robot arm’s effort to pin the mole in place.

X-37B lands after completing record mission

8:23 am

One of the Air Force’s two X-37B reusable mini-shuttle’s has landed, completing a 780-day record mission.

This was the fifth mission of the X-37B Orbital Test Vehicle. It flew for 780 days during this mission, breaking its own record by being in orbit for more than two years. As of today, the total number of days spent on-orbit for the entire test vehicle program is 2,865 days, the Air Force said. The spaceplane originally was designed to fly for just 270 days.

The mission had launched on a SpaceX Falcon 9 rocket on September 7, 2017, in a deal that had been worked out with the Air Force in June under relatively short notice.

Not surprisingly, there is no word when the next X-37B mission will fly, likely using the Air Force’s other spacecraft.

Fourth SARGE suborbital flight fails, crashes

8:17 am

Capitalism in space: The fourth flight of Exos Aerospace’s suborbital rocket failed yesterday when the rocket’s parachute apparently failed to deploy, sending the rocket crashing to the ground.

A good overview of the company and SARGE’s history can be found here. The live stream of today’s launch is embedded below the fold, cued to just before launch.

This failure appears at this moment to be far more serious than their previous failure, where the rocket shutdown prematurely but safely landed without damage using its chutes.
