Weather forces one day delay in launch of Resilience with four astronauts

9:26 pm

Because of high winds and ocean weather interfering with the recovery of the first stage, NASA and SpaceX today decided to delay the launch of SpaceX’s second manned Dragon mission, the capsule Resilience carrying four astronauts, to Sunday, November 15.

NASA and SpaceX are now targeting 7:27 p.m. EST Sunday, Nov. 15, for liftoff of the agency’s SpaceX Crew-1 mission to fly astronauts from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to the International Space Station.

Teams moved the launch by one day because of onshore winds and to enable recovery of the first stage booster, which is planned to be reused to launch the Crew-2 mission next year. The booster is expected to land on the recovery ship about nine minutes after launch.

They now plan to dock with ISS at 11 am (eastern) on November 16th.

ULA successfully launches reconnaissance satellite with Atlas 5

3:42 pm

Capitalism in space: ULA today successfully launched a military reconnaissance satellite using its Atlas 5 rocket.

This launch was the first Atlas 5 using these particular Northrop Grumman solid rocket boosters.

Because this was a military launch, the live broadcast ended at the moment the fairings were released, exposing the satellite. Final announcement of the satellite’s successful deployment will come later, assuming all goes well.

The leaders in the 2020 launch race:

30 China
19 SpaceX
5 ULA
4 Russia
4 Europe (Arianespace)
4 Rocket Lab

The U.S. now leads China 31 to 30 in the national rankings, with two more launches scheduled for the next two day. SpaceX is first with its second manned Dragon mission tomorrow, followed by Rocket Lab’s next launch from New Zealand on November 15.

A majestic terraced butte on Mars

1:35 pm

Majestic butte on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on September 8, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows an outstanding terraced butte that would rival any of the similar buttes scattered throughout the Grand Canyon, and is reminiscent especially of Wotans Throne.

What makes this butte intriguing are its terraces, the obvious result of the repeated deposition of new layers across the surface over time, and now exposed by erosion. What caused them?

As always, location provides the clues. First, this butte is found at about 15 degrees north latitude in the vast Arabia Terra transition region between the Martian northern lowland plains and the southern cratered highlands. At that latitude, we are not looking at any recent glacial features. While there might have been ice here once, it hasn’t likely been present, either on the surface or underground, for a very long time.

This conclusion becomes important once we look at the wider photo below, taken by the high resolution camera on the European orbiter Mars Express. This image gives us the immediate context.

Ukraine signs Artemis Accords

8:25 am

Ukraine has becomed the ninth nation to sign the Artemis Accords, designed to encourage private enterprise in space.

The article at the link provides little information, other than claiming that ” Ukraine has all the scientific and technical capabilities and experience that allow it to become one of NASA’s important partners in the implementation of the Artemis program.”

Russia and the Ukraine are on opposite sides of a war, with Russia attempting to steal territory, with some success. Russia has also boycotted all Ukrainian space technology, ending a half century of business dealings.

It seems that the Ukrainian government looked at this political landscape, and decided to align itself with the United States. By signing the accords, it now has the opportunity to sell its space technology to NASA, as well as participate in any American effort to get to the Moon and elsewhere. That it chose to pick an ally halfway around the world instead of its big and powerful neighbor, tells us a great deal about the Ukrainian’s opinion of Russia.

I expect there will be a NASA press release in the next day or so that will provide us additional information.

Russian spacewalk to inspect leak in Zvezda

8:13 am

The Russian spacewalk to inspect the outside location of the air leak in the Zvezda module on ISS has now been scheduled for November 18, 2020, and NASA will be providing a live stream.

Live coverage of the Russian spacewalk will begin at 8:30 a.m. EST on NASA Television and the agency’s website. The spacewalk is expected to begin about 9:30 a.m.

Ryzhikov, designated extravehicular crew member 1 (EV1), will wear a Russian Orlan spacesuit with red stripes, and Kud-Sverchkov will wear a spacesuit with blue stripes as extravehicular crew member 2 (EV2). This will be the 47th Russian spacewalk for assembly and maintenance of the station.

During the spacewalk, Ryzhikov and Kud-Sverchkov will first conduct leak inspections outside the hatch, as this will be the first spacewalk using the Poisk module for its purpose as an airlock. Next, they will relocate an antenna from another module, the Pirs docking compartment, to Poisk, the first in a series of tasks over the course of several spacewalks that will prepare Pirs for decommissioning, undocking, and disposal. The Earth-facing Pirs will be replaced by the new Russian Multipurpose Laboratory Module, named “Nauka,” Russian for “science,” which is being prepared for launch at the Baikonur Cosmodrome in Kazakhstan.

What they find could have a significant impact on the future of the space station.

MAVEN finds water loss on Mars faster than expected

12:58 pm

New data from the Mars orbiter MAVEN has found that the water on Mars moves into the upper atmosphere where it is lost to space much faster than expected.

It had previously been believed that Mars’ water loss only occurred in the lower atmosphere, which is a much slower process. Scientists had also believed that water on Mars would behave as it does on Earth, where temperatures and the atmosphere act to block it from reaching the upper atmosphere where it can easily and quickly be lost to space. Instead, MAVEN found a lot of water in the upper atmosphere.

When the team extrapolated their findings back 1 billion years, they found that this process can account for the loss of a global ocean about 17 inches deep. “If we took water and spread it evenly over the entire surface of Mars, that ocean of water lost to space due to the new process we describe would be over 17 inches deep,” Stone said. “An additional 6.7 inches would be lost due solely to the effects of global dust storms.”

During global dust storms, 20 times more water can be transported to the upper atmosphere. For example, one global dust storm lasting 45 days releases the same amount of water to space as Mars would lose during a calm Martian year, or 687 Earth days.

This data reinforces the theories that Mars once had liquid water on its surface, either as intermittent oceans or as lakes and rivers. Or it suggests that Mars once had a lot more glaciers than it does now, reinforcing a competing theory that glaciers formed the Martian features we on Earth routinely associate with flowing water.

China today launched a new communications satellite

12:47 pm

The new colonial movement: Using its Long March 3B rocket, China today launched another communications satellite for the Asian market.

No word on whether the rocket’s first stages landed near residential areas, as has happened in the past. Also no word on whether it used grid fins to control its crash somewhat, as China also did previously.

The leaders in the 2020 launch race:

30 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. and China are now tied at 30 in the national rankings. This tie won’t last long, as the U.S. has three launches scheduled for the next three days, a ULA Atlas 5 launch of a military reconnaissance satellite tomorrow, SpaceX’s second manned Dragon launch on November 14, and Rocket Lab’s next commercial launch on November 15.

Private space company announces new upgraded tug for moving satellites in orbit

12:37 pm

Capitalism in space: The private space company Spaceflight yesterday announced the development of a new upgraded tug for moving small satellites from their launched orbit to their operational locations, including locations in orbit around the Moon.

Spaceflight announced the first flight of its Sherpa-LTE orbital transfer vehicle (OTV) will take place in mid-2021. The vehicle is based on the next-generation Sherpa-FX tug announced in the summer, but equipped with the Apollo Constellation Engine, a Hall effect thruster provided by Apollo Fusion.

With that propulsion system, Sherpa-LTE will be able to generate a change in velocity, or delta-V, of more than 6 kilometers per second. That will allow the vehicle to deliver smallsats to geostationary Earth orbit, cislunar space, or Earth-escape trajectories after a launch into low Earth orbit.

Spaceflight is a direct competitor with Momentus, which already has contracts with several satellite companies for its in-space tug services. Nor is this competition bad. This new cottage industry of tugs helps focus innovation. Satellite companies can focus on improving their satellites, while buying the propulsion from tug companies who can provide that technology best.

A field of Martian knobs

12:30 pm

Knob field on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on August 9, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Uncaptioned, the image is merely dubbed a “knob field.”

I won’t spend much time trying to explain this geology. It might be related to pedestal craters, but these ridges and mesas don’t really look like those features, since they don’t really stand above the surrounding terrain.

Maybe they are a very ancient field of craters long buried, now partly exposed due to erosion, but also partly buried by wind-blown Martian sand and dust. Once again, that many of their shapes don’t resemble craters discounts this explanation.

The location of this photo is in the southern cratered highlands, as shown by the black cross in the overview map below.

Senate fails to fully fund manned lander for Trump’s 2024 lunar mission

10:30 am

The Senate appropriations committee’s budget recommendations for NASA, released yesterday, has refused to fully fund the development of the manned lander needed for Trump’s 2024 lunar mission.

The Senate Appropriations Committee released its recommendations for all 12 FY2021 appropriations bills today. The Commerce-Justice-Science (CJS) bill provides NASA with $23.5 billion, $1.75 billion less than requested. The House-passed bill keeps the agency at its current level of $22.6 billion, so the final compromise likely will be somewhere in that range. NASA’s request for Human Landing Systems (HLS) for the Artemis program was particularly hard hit on both sides of Capitol Hill.

NASA had requested $3.4 billion for building the lunar lander in time for 2024. The House appropriated $628 million. Today’s Senate recommendation budgeted $1 billion. This practically guarantees that no manned lunar mission will happen by 2024.

None of this is a surprise. The politicians in Congress from both parties don’t really want to rush this program. For them it is better to stretch it out for as long as possible, spending mucho bucks in their states and districts. Nothing will be accomplished, but they will be able to tell their constituents they brought the jobs home.

Useless and empty jobs, but jobs nonetheless.

Update on continuing engine testing of Starship prototype #8

8:45 am

Link here. The article provides details on the on-going engine tests of SpaceX’s eighth prototype of its Starship reusuable upper stage.

As should be expected, the testing has not gone exactly as planned, though clear progress is being made, especially in the testing of the header tanks in the nosecone..

After several days of test windows come and gone and an aborted attempt on November 9th, Starship SN8 finally ignited one of its three Raptor engines, feeding the engine with liquid methane and oxygen stored in two separate header tanks. Oddly, a second or two after startup and ignition, Raptor’s usual exhaust plume was joined by a burst of shiny firework-like debris. A relatively normal five seconds later, the Raptor cut off, though the engine appeared to remain partially on fire for another ten or so seconds – also somewhat unusual.

It appears that fire was from nearby debris, not the engine itself.

Another engine test is likely later this week. The actual 50,000 foot hop will not happen until they have completed all these engine tests.

NASA officially approves operational Dragon manned missions

7:03 am

Capitalism in space: NASA yesterday officially certified SpaceX’s Dragon capsule for future operational manned missions to ISS.

NASA officials gave approval Tuesday for SpaceX to begin regular crew rotation flights to the International Space Station with the launch of four astronauts set for Saturday from the Kennedy Space Center in Florida, signaling a transition from development to operations for the human-rated Dragon spacecraft.

Mission managers completed a two-day Flight Readiness Review Tuesday and issued a preliminary go-ahead for the launch of SpaceX’s Crew Dragon “Resilience” spacecraft Saturday at 7:49 p.m. EST (0049 GMT Sunday) with NASA commander Mike Hopkins, pilot Victor Glover, and mission specialists Shannon Walker and Soichi Noguchi, a veteran Japanese space flier.

The decision means that SpaceX will now be rotating crews for NASA at ISS every six months. It will also be reusing both the first stages and the capsules. Endeavour, the capsule used on the demo flight earlier this year, will be reused in the spring. Resilience, the capsule scheduled for launch on November 14th, will be reused next fall.

Since SpaceX also has a commercial manned flight planned for next fall, that will probably require a third capsule. With those three capsules they will have at least for the next few years a fleet will cover all their initial needs. Don’t be surprised if however the introduce an upgraded capsule or two along the way, based on what they learn on these initial flights.

The article had one other piece of new news concerning Boeing’s Starliner capsule. The second unmanned demo flight has now officially been delayed into the first quarter of next year, rather than late this year.

Rover update: Curiosity on the move again

1:51 pm

After spending more than three months at a single site, drilling three different holes in the same rock, Curiosity is finally on the move again, heading east and uphill toward Mt. Sharp. Yutu-2 meanwhile continues its very slow journey on the far side of the Moon. And the new rovers are halfway to Mars.

Curiosity

The image to the right, cropped and annotated to post here, shows the three drill holes that scientists had Curiosity drill in this one pavement rock, dubbed Mary Anning and located in the clay unit within Gale Crater on Mars. As I noted in my last update on July 22, 2020, the rover’s science team had made a specific detour in their planned route up Mt. Sharp in order to find this one last place to drill in this geological unit.

Though they have been very quiet about their results, apparently what they found in this one pavement rock was important enough that it required three drill holes. In addition, samples from the second hole were subjected to two of Curiosity’s limited supply of wet chemistry experiments. From the science team’s August 28, 2020 update:

Gateway already behind schedule and mismanaged

11:47 am

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

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

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

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

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

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

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

Relativity completes testing of rocket engine

9:37 am

Capitalism in space: The smallsate rocket company Relativity has successfully completed, ahead of schedule, the testing of its Aeon-1 rocket engine, and is now moving to completing design and construction of its Terran-1 rocket, tentatively scheduled for its first test flight in 2021.

The successful tests augur well for the ongoing development of the Terran 1 rocket, which represents a challenge as this rocket will now be larger than originally anticipated. In 2019, due to customer requests, Relativity resized its rocket to nearly double the available volume for payloads. It expanded the diameter of the fairing at the top of the rocket to 3 meters and height to 7 meters. While this is smaller than the fairing used in big rockets like the Falcon 9, in the class of “small satellite” launch vehicles it is quite large.

Relativity’s move to a larger fairing necessitated a more powerful engine with a gas generator cycle. The original Aeon engine had a thrust of 17,000 pounds at sea level, and the new version boosts the power considerably to 23,000 pounds. And now the company has been able to validate this larger, more powerful engine design.

The Terran 1 rocket, with a lift capacity of 1.25 tons to low Earth orbit, is powered by a first stage with nine Aeon engines. Success with the engine testing gives the company confidence that it can hit its target of launching the first Terran 1 rocket in 2021, said Zach Dunn, vice president of factory development. The next step is integrated stage testing, which will happen next year, followed by a launch from Space Launch Complex-16 at Cape Canaveral Air Force Station in Florida.

Right now it appears to me that in the race by American companies to join Rocket Lab in providing launch services for smaller satellites, Virgin Orbit and Astra are in the lead, having completed their first test flights, with Firefly and Relativity close behind.

Apophis: the asteroid that may someday hit the Earth

8:40 am

Apophis' path past the Earth in 2029
From the conference’s logo.

Last week planetary scientists held a three-day virtual conference focused on the asteroid Apophis, whose orbit regularly places it close to the Earth with a real possibility that it might someday hit the Earth.

When Apophis was originally discovered early in 2004, it wasn’t at first seen as an out-of-the-ordinary asteroid. Not much was known about it other than its albedo and that it was not trivial in size, probably around 1,000 feet in diameter. All this changed in December 2004, when further observations suggested that it had a 2.7% chance of impacting the Earth in 2029, making it the most dangerous asteroid ever discovered.

Fortunately, all subsequent observations of the asteroid have since eliminated any possibility of an impact, at least through the year 2068. Depending on what happens during the 2029 and 2036 fly-bys of Earth, there is a very small chance that it could hit the Earth in 2068, though the data says the chances of that happening are quite small (1 in 150,000).

On April 13, 2029 however Apophis will still zip past the Earth less than 20,000 miles above its surface, well within the orbit of all geosynchronous satellites. For viewers in Europe and Africa it will be a naked eye object, with a magnitude of -3.

Because the date of that close fly-by is so well known, and because this asteroid still poses a threat to the Earth, the planetary science community is very much interested in taking advantage of that close approach. From the conference’s webpage:

Knowledge is the first line of planetary defense, and the 2029 Apophis encounter is a once-per-thousand-year opportunity for investigating an asteroid as large as 350 meters passing within 6 Earth-radii. Time is of the essence as we have less than a decade to plan Earth-based and possible in-situ missions whose measurements can deliver unprecedented detailed knowledge on the physical nature of Apophis as the prototype example (poster child) of potentially hazardous asteroids.

I attended that conference, and am here now to give a summary.

Jupiter’s stormy southern polar regions

2:46 pm

Jupiter's polar regions
Click for full image.

Cool image time! The photo to the right shows the southern polar regions of Jupiter. The image, taken by Juno during its 29th close-fly of Jupiter, was enhanced by a citizen scientist who only goes by the nickname Flury-21. This in fact was this person’s first try at enhancing a Juno image. He or she did a nice job, but provided no additional information other than saying that he “used lightroom to enhance the image and mostly used the dehaze effect.”

Works nicely nonetheless to illustrate how the bands that dominate Jupiter’s equatorial and mid-latitude regions disappear at the pole. Instead, the pole is a region of chaotic independent hurricanes, many bigger than North America. Other images from Juno suggest that they change relatively quickly. For example, compare this image of the south pole with an earlier one taken during the 28th fly-by. While we might not be looking at the same hemisphere, it is hard to believe there is no overlap between both images. Yet I can find no corresponding features.

The two images of course were taken months apart, and thus it is not surprising the storms have changed completely. However, I also suspect, given their size, that even over this time span some storms have survived, but changed so much it is hard to link them together. The only way to do this would be to have an orbiter close enough all the time to make movies. Unfortunately, Juno cannot do this, and I don’t expect any orbiter like this to reach Jupiter for many decades.

Boeing hires former SpaceX software engineer

9:52 am

Capitalism in space: Boeing has hired a former SpaceX software engineer to head software development for the company.

Boeing on Friday announced it hired Jinnah Hosein as vice president of software engineering, a new role at the aerospace giant. The job will lead a centralized organization of engineers developing software across Boeing’s portfolio of products. Hosein will report to Greg Hyslop, Boeing chief engineer and senior vice president of engineering, test and technology.

…Hosein’s resume reads like a defense industry wish list of Silicon Valley stops. He worked as Google’s director of software engineering for cloud networking, helped design Tesla’s autopilot software and most recently worked as software lead for self-driving startup Aurora.

But it’s his experiences at SpaceX — where he was key to software development for the Falcon, Falcon Heavy, Dragon and Crew Dragon vehicles — that Boeing may look to draw from the most. Boeing and SpaceX have fiercely competed over NASA’s manned space programs, and SpaceX is a competitor for military space launches against the United Launch Alliance, which is co-owned by Boeing and Lockheed Martin.

Since software was the main issue that grounded Boeing’s 737-Max airplane as well as caused the serious problems on the first unmanned demo flight of the company’s Starliner capsule, this hire appears to be aimed at fixing these software issues. In both cases the management philosophy behind developing and testing software was very flawed, leaving the product saddled with software that either didn’t work properly or was not tested properly in development.

I imagine Boeing’s top management is hoping Hosein can bring to Boeing some of the agile, focused, and very successful management style found at SpaceX.

Canada’s government approves Starlink service

9:41 am

Capitalism in space: Canada’s government yesterday announced that it has given final approval to SpaceX’s Starlink internet service to offer those services in that country.

More here.

This final approval came from the Innovation, Science and Economic Development Canada (ISED) agency, which appears designed to protect Canadian businesses from foreign competition. It had appeared initially that they had been stalling giving their approval (maybe for political reasons). The delay however could simply have been the slowness of operation which is typical of such government bureaucracies. As noted at the first link above, however “Clearly, the government heard the demand from consumers to get this service approved.” And since there are no Canadian companies that can offer this service, it was absurd not to okay SpaceX’s operation.

This approval means that Starlink is now posed to begin commercial operations, actually selling its internet service to the public, and doing it ahead of its primary competitor, OneWeb. Considering that OneWeb had started development and satellite launching first, this achievement illustrates again SpaceX’s nimble and fast approach to business. The company does not waste time in anything it does. It might not meet all of its scheduling goals, but not for want of trying.

SpaceX has already been offering the service in its test market in the northern U.S. for the price of $99 per month plus an initial fee of $499 for equipment, with the initial user reports very positive.

Chinese pseudo-company launches first satellite

9:21 am

The new colonial movement: The pseudo-private Chinese company Galactic Energy today successfully completed its first orbital launch, placing a small satellite into orbit using its Ceres-1 rocket.

Galactic Energy is the fourth Chinese private launch company overall to make an orbital launch attempt, all with light-lift solid launchers. Landspace made the first attempt in October 2018, with OneSpace following in March 2019. In July last year iSpace became the first to successfully achieve orbit with its Hyperbola-1 launch.

The 19-meter-long, 1.4-meter-diameter Ceres-1 can loft 350 kilograms to low Earth orbit or 230 kilograms to a 700-kilometer SOO. It consists of three solid stages and an advanced liquid upper stage. [emphasis mine]

That all of these companies are using solid rockets explains why I call them “pseudo private.” They might be raising independent venture capital money to fund their operations, and they might be aimed at earning a profit, but solid rocket technology is always the primary technology used for military missiles, and none of these Chinese companies could do anything without the close and very firm permission and supervision of the Chinese communist government. In fact, their very existence is likely because that Chinese communist government wants them to exist.

Nonetheless, this launch raises China’s launch capabilities. The leaders in the 2020 launch race:

29 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. is still ahead of China, 30 to 29, in the national rankings.

India successfully completes first launch in 2020

9:10 am

For the first time in 2020 India has launched a rocket, successfully placing ten satellites into orbit using its PSLV rocket.

The primary payload was an Indian Earth resource satellite dubbed EOS-1.

When the year started ISRO, India’s space agency, had predicted it would complete twelve launches in 2020, which would have been a record for their nation. Then the panic over COVID-19 set in, and they canceled everything for months on end. This long stand down will likely cause delays in all their long term programs including their effort to launch their own astronauts on their own rocket in their own capsule.

The leaders in the 2020 launch race remain the same:

28 China
19 SpaceX
12 Russia
4 ULA
4 Europe (Arianespace)
4 Rocket Lab

The U.S. remains ahead of China 30 to 28 in the national rankings..

NASA offers public chance to experience next manned mission virtually

9:25 am

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

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

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

Company defends its satellite constellation from NASA criticism

9:21 am

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

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

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

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

United Arab Emirates announce plans for lunar rover mission

7:59 am

The new colonial movement: The United Arab Emirates (UAE) has announced plans to launch its first unmanned probe to the Moon, a small rover dubbed Rashid with a target launch date in 2024.

The Mohammed Bin Rashid Space Centre (MBRSC) in Dubai says its in-house teams will develop, build and operate the 10-kilogram rover, which is named after the late Sheikh Rashid bin Saeed Al Maktoum, who ruled Dubai at the UAE’s creation in 1971.

The team will hire an as-yet unannounced space agency or commercial partner to carry out the launch and landing, the riskiest part of the mission. If successful Rashid would be one of several rovers made by private firms and space agencies that are set to populate the Moon by 2024.

This project is a great opportunity for the various new private aerospace companies in the U.S. developing interplanetary capabilities for sale to others.

Rocket Lab will try to recover 1st stage on next launch

3:04 pm

Capitalism in space: Rocket Lab announced today that it will attempt to recover the 1st stage of its Electron rocket on its next launch, using parachutes to slow its descent into the ocean and then fishing from the sea.

On its next mission set for liftoff later this month, Rocket Lab will try to recover the first stage of its Electron small satellite launcher after parachuting into the Pacific Ocean downrange from the company’s privately-run spaceport in New Zealand, officials announced Thursday.

The attempt to retrieve the Electron rocket’s first stage moves Rocket Lab closer to eventually capturing falling boosters in mid-air with a helicopter, then reusing the hardware. The reuse initiative is aimed at increasing Rocket Lab’s flight rate, and could result in cost savings, according to Peter Beck, the company’s founder and CEO.

The flight is presently scheduled for November 15 from New Zealand. It appears the goal with this recovery is not to reuse the 1st stage, but to recover it so they can determine how it fared during re-entry. For re-use they will capture the first stage using a helicopter, before splashdown and is exposed to saltwater.

When they attempt the helicopter capture on an actual launch remains unclear.

Terraced mesa inside Martian depression

Terraced mesa inside depression
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on July 1, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a very puzzling terraced mesa inside an enclosed depression or sinkhole (the western half of which can be seen in the full image).

What caused that mesa? A first scan of the image and the data suggests we are looking at sinkage related to the melting of an underground ice table. The latitude here is 34 degrees south, just far enough away from the equator for glacial activity to be possible. Moreover, the small circular depression in the upper right of the image strongly suggests an impact crater into slushy material. The implication is that this depression is the result of the melting or sublimation of underground ice, leaving behind a mesa that is made of solider stuff.

Another possibility is that the terraced mesa is actually the remains of glacial material. In the full image features inside other nearby depressions are terraced also, but are also much more reminiscent of glacial features found in many craters in the mid-latitudes. The depression is also close to the headwaters of Reull Valles, a meandering canyon where many images have shown glacial features (see for example here, here, and here).

These features however could also have nothing to do with water ice.
