On October 24th, Ingenuity successfully completed its 14th flight on Mars, a short test hop up and down to see if the helicopter could function properly as the air pressure in the Martian atmosphere drops due to seasonal variations.

As planned, the helicopter executed its first 2,700 rpm flight, proving that Ingenuity is capable of flying in the weeks and months ahead on Mars, during which seasonal changes on the surface will result in decreases in air density. The short 23-second flight included a peak altitude of 16 feet (5 meters) above ground level, with a small sideways translation of 7 feet (2 meters) to avoid a nearby sand ripple.

I predict the next flight will head north, leap-frogging past Perseverance to get a better view of the South Seitah area so that the rover team can decide whether they can continue north through that terrain or retreat backwards.

China resumes communications with Zhurong Mars rover

10:13 am

Elevation map of Zhurong location

The new colonial movement: China yesterday announced that it has regained communications with its Zhurong rover, located in the Martian northern lowland plains of Utopia Planitia.

The image to the right, cropped and annotated by me to post here, is a digital terrain map created from two high resolution photos taken by Mars Reconnaissance Orbiter (MRO). The black line shows the route Zhurong has traveled since landing in May.

According to [Chen Baichao, the chief designer of Zhurong], the rover has traveled more than 1,000 meters since it landed on Mars at the southern part of Utopia Planitia in May 2021. After the solar conjunction, it will head south to find mud volcanoes, which scientists are interested in, located about 10 km away.

American scientists had hoped Zhurong would head north to a much larger mud cone that was much closer. Their decision to head south to the smaller cones farther away tells us that they have given themselves a much more challenging mission. It also suggests they decided it will be easier to get Zhurong closer to a smaller cone.

Based on that 10 kilometer distance, it seems the Chinese are aiming for the cones near the bottom of the map. It took Zhurong three months to travel the distance shown. At that pace, to get to those small southern mud cones will likely take, at a minimum, about fifteen months. Though the ground is quite flat, the rover will either have to negotiate one small rise of about 15 feet, or detour to the east somewhat to find a less steep route.

It is also possible that they will instead head to the mud cone south of the large impact crater. It is also a small cone, is much nearer, and will not require them to get past that rise.

Firefly approves design of its unmanned lunar lander

9:08 am

Capitalism in space: Firefly has completed and approved the design of its unmanned lunar lander, and will now begin construction with a launch date targeting 2023.

Firefly said Monday that it has completed the “critical design review” phase of its program to develop a lunar lander. This means the company can now proceed to build and order components for the “Blue Ghost” spacecraft and begin its assembly. Firefly aims to launch the spacecraft as the primary payload on a Falcon 9 rocket in the fall of 2023.

NASA is sponsoring the mission as part of its Commercial Lunar Payload Services Program, through which it pays private companies to deliver scientific experiments to the Moon. NASA is paying $93.3 million for this Blue Ghost mission, which will carry 10 payloads down to the Mare Crisium lunar basin in September 2023.

In the next three years a plethora of commercial unmanned lunar landers have scheduled flights, all bringing both NASA science as well commercial payloads to the lunar surface. All are being designed and built by private companies. Expect some to fail. Some however will succeed, and will thus establish themselves as the go-to companies if you want to put a payload on the Moon.

Russians certify Dragon for flying its astronauts

9:02 am

Capitalism in space: The head of Russia’s space agency Roscosmos, said yesterday that they have finally approved the use of SpaceX’s Dragon capsules to launch their astronauts to ISS.

Crew Dragon spaceships of Elon Musk’s SpaceX company have gained substantial experience for Russian cosmonauts to travel aboard them as part of cross flights, Head of Russia’s State Space Corporation Roscosmos Dmitry Rogozin said on Monday. “From our viewpoint, SpaceX has gained sufficient experience for representatives of our crews to make flights aboard its spacecraft,” the Roscosmos chief told reporters at the 72nd international astronautical congress.

Russia will now begin barter negotiations for the future flights, whereby for each Russian that flies on Dragon an American will get a free flight on Soyuz.

Smallsat rocket startup ABL raises $200 million in anticipation of 1st launch

8:58 am

Capitalism in space: With its first test launch of its rocket scheduled for mid-December, the smallsat rocket startup ABL has raised $200 million in investment capital, in addition to the $170 million it had raised in March.

Dan Piemont, president and co-founder of ABL, told SpaceNews that the company still has most of the $170 million it raised in March, describing the new round as “somewhat opportunistic and driven by insider interest.” Much of the additional funding, though, will go to scale up production of its RS1 vehicle that is nearing its first launch. “We have received large orders for RS1 and will need to scale faster than we previously planned to meet the demand,” he said, with more than 75 launches under contract. “Our investors have seen the incredible demand for RS1 and want to make sure we have all the resources we need to serve it. We updated our operating plan accordingly, and you’ll see that in the form of more launch sites, more facilities, more machines and larger production crews next year.”

ABL is one of seven rocket companies — the others are Virgin Orbit, Astra, Firefly, Relativity, Aevum, and Blue Origin — that had planned a first test launch in ’21. Of those, Virgin Orbit has had two successful orbital launches, while Astra and Firefly have attempted orbital launches but failed. Blue Origin’s first launch of its New Glenn rocket has been delayed to next year, but it is questionable it will occur then. The launch dates for Relativity and Aevum remain unannounced.

Japan launches GPS-type satellite

8:20 pm

Japan successfully launched a government GPS-type satellite, using the H-2A rocket that is built by Mitsubishi.

This was Japan’s first launch in 2021. It appears this year it will not match last year’s launch total of four.

The leaders in 2021 launch race remains unchanged:

37 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA
4 Arianespace (Europe)

China still leads the U.S. 37 to 36 in the national rankings.

Layered glaciers in Mars’ glacier country

Layered glacier in Mars' glacier country
Click for full image.

Cool image time. The photo to the right, cropped and reduced to post here, was taken on August 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows two different impact craters in a glacial region dubbed Nilosyrtis Mensae, located in the northern mid-latitudes in the 2,000 mile long strip chaos terrain that I have labeled glacier country because practically every image finds them there.

The splash apron surrounding the larger crater is typical of craters in Martian regions where ice is thought to be near the surface.

What makes this picture interesting is that the glaciers appear layered. You can see evidence of this in the mounds inside both craters. Those mounds appear to represent earlier periods when there was more ice here. Since then the mounds have partly sublimated away.

You can also see evidence of layers in the material surrounding the nearby larger mounds.

The map below shows us where this image is, relative to all of glacier country as well as the rover Perseverance in Jezero Crater.

Sierra Space teams up with Blue Origin to build its Life space station

10:45 am

Proposed Orbital Reef space station

Capitalism in space: Sierra Space and Blue Origin today announced [pdf] that they are forming a consortium of space companies to build a space station they dub Orbital Reef. From the press release:

The Orbital Reef team of experts brings proven capabilities and new visions to provide key elements and services, including unique experience from building and operating the International Space Station:

  • Blue Origin – Utility systems, large-diameter core modules, and reusable heavy-lift New Glenn launch system.
  • Sierra Space – Large Integrated Flexible Environment (LIFE) module, node module, and runway-landing Dream Chaser spaceplane for crew and cargo transportation, capable of landing on runways worldwide.
  • Boeing – Science module, station operations, maintenance engineering, and Starliner crew spacecraft.
  • Redwire Space – Microgravity research, development, and manufacturing; payload operations and deployable structures.
  • Genesis Engineering Solutions – Single Person Spacecraft for routine operations and tourist excursions.
  • Arizona State University – Leads a global consortium of universities providing research advisory services and public outreach.

I suspect that this deal is actually telling us that Jeff Bezos is spreading some of his Blue Origin money to help finance Sierra Space’s work. The deal also appears to be an effort to generate work for Blue Origin’s not-yet-launched New Glenn rocket and Boeing’s not-yet launched Starliner capsule.

The release says nothing about target dates, but the overview [pdf] on the Orbital Reef website says they are aiming for the second half of this decade.

While the success of such a project can only increase the competition and lower the cost to orbit, thus making the settlement of space more likely, this announcement reeks of the same kind of high-minded promises that came with Blue Origin’s Blue Moon lunar lander: Big plans by the best and most established space companies, with little firm commitment by these companies to actually build anything.

Compared to the Blue Moon lunar lander project, however, this project has one very significant difference that could make it real. Orbital Reef is not being touted in order to win a government contract. It is being touted as a commercial station for private customers. Such a project will require these companies to either invest their own money, or obtain outside investment capital, to build it. To make money they can’t sit and wait for their customers to pay for it, since customers never do that (except the government). They need to first build it.

Meanwhile, the BE-4 engine is not yet flight worthy, so that Blue Origin’s New Glenn rocket remains no closer to launch, even though it is now approaching two years behind schedule.

Space Adventures fails to find customer for Dragon orbital flight

10:35 pm

Capitalism in space: A high orbital tourist flight on SpaceX’s Dragon capsule has been cancelled because the company organizing it, Space Adventures, apparently failed to find enough customers.

Company spokesperson Stacey Tearne confirmed to SpaceNews that the company had dropped plans for the mission. “The mission was marketed to a large number of our prospective customers, but ultimately the mix of price, timing and experience wasn’t right at that particular time and our contract with SpaceX expired,” she said. “We hope to revisit the offering in the future.”

This revises the list of scheduled of orbital tourist flight that began with SpaceX’s Inspiration4 flight in September.

  • September 15, 2021: SpaceX’s Dragon capsule flew four private citizens on a three day orbital flight
  • October 5-17, 2021: Two Russians fly to ISS for 12 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • January/February 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Why Space Adventures could not get enough customers for their Dragon flight is unclear. It could be for many reasons outside of not enough demand. For example, SpaceX might have determined that the prospective customers were not physically capable for the flight. Maybe Space Adventures sold two or three tickets, but couldn’t fill the manifest before their SpaceX contract expired.

The cancellation however does suggest that the price per ticket might have to come down to garner business for orbital tourist space flights. Or those flights need to arrive at a space station where the passengers can spend more than two or three days.

Arianespace and Chinese launches this weekend

10:25 pm

Two launches occurred this weekend.

First Arianespace used its Ariane 5 rocket to place two communications satellites in orbit, one for the French military and the second for the commercial company SES. The total payload weight set a record for the rocket.

With this success the path is now clear for the launch of the James Webb Space Telescope on the next Ariane 5 launch in December.

Next the Chinese used its Long March 3B rocket to launch a technology test satellite aimed at testing “space debris mitigation technologies.” No other information was released.

The leaders in the 2021 launch race:

37 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA
4 Arianespace (Europe)

China now leads the U.S. 37 to 36 in the national rankings.

Musk: Starship orbital flight could happen as soon as next month

2:57 pm

Capitalism in space: Elon Musk today announced that SpaceX will be ready to launch the first orbital flight of Starship as soon as one month from now.

“If all goes well, Starship will be ready for its first orbital launch attempt next month, pending regulatory approval,” Musk tweeted today [emphasis mine]

Musk’s tweet came one day after the FAA completed its public hearings on its environment reassessment of SpaceX’s operations in Boca Chica. Before the agency can approve that reassessment it has to digest the comments, then to hold an “industry workshop” on this reassessment.

Thus, while SpaceX is ready to go, our lumbering, oppressive government is not. As I’ve written before, I fully expect there to be pressure from the Biden administration and NASA to slow walk that government approval so that Starship does not launch before February 2022, when SLS is now scheduled for its first launch. Having SpaceX get its heavy lift rocket into orbit before NASA would be very embarrassing, considering that SpaceX has spent about a third the time and about a tenth the money getting it done.

I hope I am wrong, but this is what I expect from the corrupt federal government we now have.

NASA sets target launch date for SLS in February ’22

2:51 pm

As expected, the first unmanned demo launch of NASA’s SLS rocket has now been scheduled for a February launch window.

The first launch window for NASA’s Artemis I mission opens on February 12 at 5:56 p.m. EDT – yes, we have dates and times for this long-awaited mission. The February window lasts two weeks, with the first half of that window allowing a six-week mission and a four-week mission on the back half.

If for some reason NASA cannot launch in that firs window, they have back up windows in March and April. These windows exist because the plan is to send the Orion capsule to orbit the Moon from four to six weeks, and then return to Earth.

The announcement came the day after NASA had finally stacked the Orion capsule on top of the SLS rocket, essentially completing the rocket’s assembly.

Next Ariane 5 launch postponed

11:39 am

Arianespace today announced that it has postponed its next Ariane 5 launch of two communications satellites, scheduled for October 22nd, because of issues with ground equipment.

Though there appear to be no issues with the rocket, this delay could effect the launch of the James Webb Space Telescope in December on another Ariane 5 rocket. Arianespace has said that it wants to complete this launch first, to make sure the fixes it completed on the rocket’s fairing are truly working.

It was those problems that shut down all Ariane 5 launches for almost a full year.

No new launch date has been set. Normally, ground equipment issues cause short delays, so we should be hopeful all will be fixed quickly and this launch will be quickly rescheduled and take off without problems.

Cool image time! The photo above was cropped and enhanced by citizen scientist Gerald Eichstädt from a raw Juno image taken during that spacecraft’s 37th orbit. I have reduced it slightly to post here.

The photo shows what he calls “pop-up” clouds floating above a much larger cloud eddy. Unfortunately, Eichstädt provides no scale, but I suspect this image would easily cover the Earth, with those white clouds probably far larger than the biggest hurricane on Earth.

Ukraine and Nova Scotia to partner in spaceport deal

8:59 am

The new colonial movement: The Ukraine has agreed to be a partner in the building of a new spaceport in Nova Scotia.

It appears a Canadian company, Maritime Launch Services (MLS) has raised $10.5 million in investment capital to develop both the spaceport and a rocket it dubs Cyclone-4M. That company has also been negotiating with the Ukraine to buy engines from its two rocket engine manufacturers, Yuzhnoye and Yuzhmash, for that rocket. As part of the negotiations, the Ukrainian government has agreed to provide funding to these two companies.

Both sides will hold further meetings in Canada on this partnership in November, including top Ukrainian government officials, Deputy Prime Minister Oleg Uruskyi, State Space Agency of Ukraine Administrator Vladimir Taftai, and Foreign Affairs Minister Dmytro Kuleba.

China resumes communications with Tianwen-1 Mars orbiter

8:45 am

With the Sun no longer between the Earth and Mars, China has re-established communications with its Tianwen-1 Mars orbiter.

According to the CNSA [China National Space Administration], the orbiter will enter the remote-sensing orbit of Mars in early November to carry out global detection and obtain scientific data such as morphology and geological structure, surface material composition and soil type distribution, atmospheric ionosphere, and space environment of Mars.

The orbiter will also relay the communication between the rover and Earth for the rover’s extended mission, the CNSA added.

Based on this information, full communications with the rover Zhurong will not resume until November because the orbiter needs to re-adjust its orbit.

Nanoracks and Lockheed Martin to partner in building commercial space station

10:07 pm

Capitalism in space: The companies Nanoracks and Lockheed Martin have announced that they have formed a partnership to build their own private commercial space station, dubbed Starlab.

Nanoracks, its majority owner Voyager Space and Lockheed Martin, will collaborate on the development of a commercial space station as others in industry warn of a potential space station gap.

Nanoracks said Oct. 21 that it was partnering with Lockheed Martin and Voyager Space on a commercial space station called Starlab. Nanoracks will be the prime contractor with Voyager handling strategy and investment and Lockheed serving as the manufacturer and technical integrator.

Starlab would consist of a docking node with an inflatable module attached to one side and a spacecraft bus, providing power and propulsion, attached to the other side. Starlab will have a volume of 340 cubic meters, about three-eighths that of the International Space Station, and generate 60 kilowatts of power. Starlab will be equipped with a robotic arm and “state-of-the-art” lab, and be able to host four astronauts at a time.

They are aiming for a 2027 launch.

Curiosity’s new mountain views

Curiosity's future route
Click for full image.

With the resumption of communications with Mars, following the two week hiatus because the Sun was in the way, Curiosity is about to begin its travels again. The view above, taken by the right navigation camera and reduced and annotated to post here, looks forward, with the red dotted line indicating the planned route.

The distinct white outcrop on the right top is the same spectacular outcrop I have highlighted previously.

At the moment however the rover is not going anywhere. Just before the hiatus the scientists had Curiosity move a short distance to crush some nearby nodules so that they could see their interior. At their update they post an image of one crushed nodule, and write the following:

[L]ook closely for very straight imprinted lines in the middle of flattened areas that appear slightly more grey. You can also see cracks, especially clearly on the right of the nodule in the image, but if you look around, you’ll find there are more of them. Some of the scratched areas are looking white, too. All those features will allow us an insight into the nodules and an interpretation beyond what we can otherwise see on the surface.

The image below, also taken by the right navigation camera and reduced to post here, looks back at Curiosity’s earlier travels, across the floor of Gale Crater about 1,500 feet below. The rim, about 25 miles away, can be seen through the atmospheric haze as the distant mountain chain.

See the orbital map at this post in September to get the context of what the two images are viewing. The top image looks south along the cliff line, the bottom looks almost due north.

A collapsing north wall in Valles Marineris

Mass wasting in Valles Marineris
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on July 17, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as an alluvial fan.

I have also seen them label this kind of avalanche as mass wasting, where the material moves down slope suddenly in a single mass.

The image shows the aftermath of such an event, after a large blob of material broke free from the mountainside and slid almost as a unit downhill to settle more than two miles away on the floor of the canyon. The distance traveled and the blobby nature of the flow both reveal how the lower Martian gravity changes the nature of such events, compared to what you might see on Earth. The flows can travel farther, and can hold together as a unit easier.

The overview map below not only provides the context, but it tells us that such events are remarkably common in this place.

Russian filmmakers describe their experience of filming a movie in space

9:06 am

Capitalism in space: The Russian actress Yulia Peresild and her director Klim Shipenko — who spent twelve days on ISS filming scenes for a science fiction movie — gave a press conference yesterday, describing their experience and what they accomplished.

They shot more than 30 hours worth of footage which will later be edited down to about 30 minutes. “We’ve shot everything we planned,” Shipenko said from the Yuri Gagarin Cosmonaut Training Center outside Moscow.

The 38-year-old US-educated film director said cinema was ready to conquer space. “Cinema is looking for new forms. The cosmos is also ready to welcome various experimentalists,” said Shipenko.

He said his stint on the ISS was full of professional discoveries and added that he would never have been able to shoot on Earth what he had shot in space.

Both regretted that their work scheduled on ISS was so busy that they did not have enough time to look at the views out the station’s windows.

When this movie is finished I wonder if it will get a distribution deal in the west. I certainly would like to see it, and I am certain many other Americans will feel the same.

Rocket Lab to attempt another recovery of 1st stage on next launch

8:57 am

Capitalism in space: In its next launch in mid-November, Rocket Lab will attempt another recovery of the first stage of its Electron rocket.

Rocket Lab USA, Inc (“Rocket Lab” or the “Company”) (Nasdaq: RKLB) has today revealed it will attempt a controlled ocean splashdown and recovery of the first stage of an Electron rocket during the company’s next launch in November. The mission will be Rocket Lab’s third ocean recovery of an Electron stage; however, it will be the first time a helicopter will be stationed in the recovery zone around 200 nautical miles offshore to track and visually observe a descending stage in preparation for future aerial capture attempts. The helicopter will not attempt a mid-air capture for this mission but will test communications and tracking to refine the concept of operations (CONOPS) for future Electron aerial capture.

The eventual goal is for the helicopter to snatch the stage by its parachutes as it descends, and then bring it back to deposit it gently on land. This next launch will likely provide the company the data it needs to make that maneuver more safely and with a greater chance of success on a future launch.

The November splashdown recovery will follow two previous successful such recoveries. In addition, the company has also done a test whereby one helicopter dropped a dummy first stage, its parachutes opened, and a second helicopter successfully grabbed it. With the addition of the helicopter on this launch it will likely be poised to attempt a full recovery out of the air.

Israel & UAE sign deal to work together on space projects

8:45 am

The new colonial movement: This week Israel and the United Arab Emirates (UAE) signed an agreement calling for them to work together on a variety of space projects.

Israel and the United Arab Emirates signed a historic deal regarding space missions, Ynet reported on Tuesday, which will include collaborating on the Israeli rocket ship “Beresheet 2” space project bound for the Moon.

As part of the agreement, the two nations will work together on data-based development and research from the Israeli-French satellite Venus, while students from the UAE will work with Israeli students on a new satellite tracking the Moon.

The lack of general excitement over this agreement is truly astonishing. Remember, just a few years ago no Arab nation could dare reveal any partnership or even direct communication with Israel, out of fear of the violent reaction throughout the Islamic world. Now, the UAE can sign a deal where its citizens will work side-by-side with Israelis on several different projects, and the world barely notices.

More than anything, this disinterest signals the importance of the Abraham Accords engineered by the Trump administration. Those agreements, disavowed by the Biden administration, made this partnership possible.

Senate committee: NASA must choose two companies to build manned lunar lander

5:09 pm

We’re here to help you! Despite offering NASA only $100 million more for the program, the Senate Appropriations committee has directed the agency to award a second manned lunar lander contract, in addition to the one it gave SpaceX in April.

On Tuesday (Oct. 18), the Senate Appropriations Committee — the largest U.S. Senate committee that oversees all discretionary spending legislation in the Senate — released a draft report of nine appropriations bills for the fiscal year 2022 which included funding for NASA, according to SpaceNews.

The appropriators, in the report, state that NASA’s HLS program is not underfunded, despite the agency’s previous claims to the contrary. As shown in the report, the bill includes $24.83 billion for NASA, which is just slightly more than the $24.8 billion that NASA requested, and a $100 million increase in funding for HLS.

“NASA’s rhetoric of blaming Congress and this Committee for the lack of resources needed to support two HLS teams rings hollow,” the report states. The committee added that “having at least two teams providing services using the Gateway should be the end goal of the current development program,” referencing NASA’s Gateway, a planned lunar space station.

It might be possible for the increase in funding to cover a second contract, if that contract was awarded to Blue Origin. Jeff Bezos has made it clear that he would be willing to waive as much as $2 billion of the price for the contract, using his own ample funds to make up the difference. Whether that is enough to build it, with the $100 million the Senate appropriated, is unclear.

This bill of course has to pass the Senate, be approved as written by the House, and then signed by the President. These directives and budget changes thus might not end up in the final appropriations bill.

Boeing to take Starliner apart, remove two valves

4:57 pm

Boeing has decided to take apart the Starliner capsule intended for its second unmanned demo flight to ISS to do a close inspection of two of the troublesome valves that caused the launch in August to be scrubbed.

The current guess at what caused the valve issue involves moisture that accumulated near some of the valves’ Teflon seal. But without any clear culprit, the company now plans to ship two of the valves to a NASA center in Huntsville, Ala., for a forensic CT scan, using machines similar the ones used on humans to detect diseases.

This action now means that the next launch attempt will likely be delayed until the middle of ’22.

The delay is costing Boeing money, not NASA, as the contract is fixed price and Boeing will not get paid additional money until it meets its next milestone, which is a successful demo flight to ISS.

Did China test a hypersonic weapon in August?

10:14 am

Long March 2C rocket
China’s Long March 2C rocket

On October 17th The Financial Times published a story claiming, based on anonymous sources, that one of China’s five launches in August tested a hypersonic weapon, which supposedly circled the globe to impact the Earth only 24 miles from its target.

The Financial Times story is behind a paywall, but not surprisingly it was picked up by much of the mainstream press, with the conservative press — as illustrated by this Daily Wire story — accepting the weapon as fact, while the leftist press — as illustrated by this CNN story — giving China the opportunity to deny the claim.

Did it actually happen? I have no idea. I would add however that I would not trust any story dependent wholly on anonymous sources, considering the unreliability of today’s press and the repeated evidence that numerous federal agencies in the military and intelligence communities routinely feed it disinformation for their own political purposes. These agencies, including the Space Force, want to encourage Congress to fund them, and creating a bogey man threat that the press can tout has for decades been the standard way to do it.

To get a better idea whether this hypersonic flight happened, let’s review the actual Chinese launches in August to see if any might be a likely candidate. For a launch to fit the description, there would have to be almost no information about its payload, and that payload would have to have not reached orbit, since the hypersonic test circled the globe once and then impacted the Earth.

Scientists resume communications with U.S. Martian rovers

9:11 am

Example of first rover images downloaded following communications break
Click for full image.

Both U.S. Mars rovers Curiosity and Perseverance have resumed communications with Earth, each downloading a bunch of images that they had been programmed to take during the two week communications hiatus from October 3 to October 17, caused by the Sun being between the Earth and Mars.

Most of the images are a variation of the one to the right, reduced to post here, taken by Curiosity’s left hazard avoidance camera. As neither rover moved during the communications break, the scientists limited most photography to only a handful of cameras, with the photographs mostly confirming day to day that the rover and its instruments were functioning.

You can see all of Curiosity’s new images here. Perseverance’s new images can be viewed here. (To see the new Perseverance images click on “latest images.”)

A Curiosity team update today notes the work they plan to do in the coming days as they gear up for future travels. The Perseverance update today focused more on the paper published during the break that confirmed, using data from the rover, that Jezero Crater once contained a lake.

First FAA hearing on Starship environmental assessment dominated by supporters

8:48 am

Capitalism in space: The FAA yesterday conducted its first of two virtual public hearings to allow public comment on its proposed environmental assessment that would allow SpaceX to launch orbital Starship missions from Boca Chica, Texas>

According to the story at the link, the comments were dominated by supporters, interspersed with the typical small number of anti-development environmental activists.

Over the course of more than three hours on Monday, members of the public who had registered in advance were given three minutes each to deliver their oral public comments on Starship and the draft. Most were in favor of SpaceX, though many positive comments appeared to originate from outside of Texas. A smaller number of people also voiced concerns about impacts on local ecosystems and species near Boca Chica.

The second hearing is scheduled for tomorrow.

Parker probe completes fifth Venus flyby

8:40 am

The Parker Solar Probe on October 16th successfully completed its fifth flyby of Venus, designed to lower its solar orbit around the Sun.

At just after 5:30 a.m. EDT, moving about 15 miles (24 kilometers) per second, the spacecraft swooped 2,370 miles (3,814 kilometers) above Venus’ surface. Such gravity assists are essential to the mission to bring Parker Solar Probe progressively closer to the Sun; the spacecraft counts on the planet to reduce its orbital energy, which in turn allows it to travel closer to the Sun and measure the properties of the solar wind near its source.

This was the fifth of seven planned Venus gravity assists. The flyby reduced Parker Solar Probe’s orbital speed by about 6,040 miles per hour (9,720 kilometers per hour), and set it up for its 10th close pass (or perihelion) by the Sun, on Nov. 21.

Parker Solar Probe will break its own distance and speed records on that closest approach, when it comes approximately 5.3 million miles (8.5 million kilometers) from the Sun’s surface — some 1.2 million miles (1.9 million kilometers) closer than the previous perihelion on Aug. 13 – while reaching 101 miles (163 kilometers) per second, or 364,621 miles per hour. Assisted by two more Venus flybys, in August 2023 and November 2024, Parker Solar Probe will eventually come within 4 million miles (6.2 million kilometers) of the solar surface in December 2024.

That speed record, 364,621 miles per hour, is the fastest any human built object as ever traveled.

According the Lucy science team, the spacecraft’s solar panels are generating more than 90% of the expected power at this stage of the mission, despite the fact that one panel did not deploy completely and has not latched in final position.

“We’re very happy to report that we are getting most of the power we expected at this point in the mission,” said Joan Salute, associate director for flight programs at NASA’s planetary science division. “It’s not 100%, but it is fairly close. So that is great news.’

In an interview with Spaceflight Now, Salute said the power output from the solar arrays appears to be “most likely above 90%” of the expected level of 18,000 watts. “We don’t know if it’s a latch problem, or that it is only partially deployed,” Salute said.

If correct, there is an excellent chance the mission will not be seriously hindered, even if they cannot get the panel fully deployed or latched. At the same time, there are worries about firing Lucy’s main engine for major course corrections with the panel unlatched. The first major course correction is scheduled for mid-November.

The engineers are presently reviewing their data. One option might be to order the spacecraft to re-attempt a full deployment, in the hope that the process will complete during that second attempt.

The icy Phlegra Mountains on Mars

1:37 pm

Overview map

Cool image time! The Phlegra Mountains on Mars are probably the iciest mountains on the red planet, something I noted previously in an April 2020 essay, highlighting a half dozen images from the high resolution camera on Mars Reconnaissance Orbiter (MRO) that showed that iciness. As I stated:

Here practically every photograph taken by any orbiter appears to show immense glacial flows of some kind, with some glaciers coming down canyons and hollows [#1], some filling craters [#2], some forming wide aprons [#3] at the base of mountains and even at the mountains’ highest peaks [#4], and some filling the flats [#5] beyond the mountain foothills.

And then there are the images that show almost all these types of glaciers, plus others [#6].

The overview map above not only shows the locations of these six images in black, it also shows in red two of SpaceX’s four prime candidate landing sites for its Starship spacecraft. Note that #3 above is one of those sites.

The white rectangle in the Phlegra Mountains marks the location of today’s cool image below, taken on June 11, 2021 by MRO’S high resolution camera.
