SpaceX successfully launches 40 OneWeb satellites

3:39 pm

SpaceX today used its Falcon 9 rocket to successfully launch 40 OneWeb satellites, joining with India to replace the launch services of Russia.

This was the first SpaceX launch for OneWeb. The first stage completed its fourth flight, landing back at SpaceX’s launchpad at Cape Canaveral. The fairings completed their fifth and sixth flights.

The leaders in the 2022 launch race:

55 China
55 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. nowl leads China 79 to 55 in the national rankings, though it still trails the entire world combined 86 to 79.

Sweden upgrading suborbital launchsite for orbital business

8:52 am

A Swedish launchsite that the European Space Agency (ESA) has used on and off for decades for suborbital test launches is now being upgraded to make it attractive to smallsat rocket companies.

Founded by the European Space Agency (ESA) in 1966 to study the atmosphere and Northern Lights phenomenon, the Esrange space center has invested heavily in its facilities in recent years to be able to send satellites into space.

At a huge new hangar big enough to house two 30-meter rockets currently under assembly elsewhere, Philip Pahlsson, head of the “New Esrange” project, pulls up a heavy blue door. Under the rosy twilight of this early afternoon, construction machines nearby can be seen busily completing work on three new launch pads. “Satellite launches will start to take place from here next year,” Pahlsson says.

In Europe, Esrange is competing with a new Norway spaceport for the first orbital rocket launch. It is also competing with two spaceports in Scotland. And the one that makes launches easy for the new smallsat rocket companies is going to garner the most business.

Why We Fight: The Nazis Strike

6:01 pm

An evening pause: For tonight, the anniversary of the Japanese sneak attack on Pearl Harbor, I think this documentary created by Frank Capra for the U.S. government in 1943 is most appropriate.

Though created to rally Americans to the war effort, the film is not propaganda. It is a remarkably accurate telling of the history leading up to Pearl Harbor in detailing how Hitler was able to gain control of almost all of Europe, through lies, force, and the weak-kneed opposition of his opponents. Only with Soviet Russia and its secret pact with Germany to divide up Poland does the film fail to tell the facts thoroughly, but here it fails by omission, not lies. In the end, however, it is accurate, because the Soviet Union’s pact, intended to bring it security from German invasion, failed. Hitler had lied once again, and the U.S.S.R. became only another victim of his greed for power.

It is worthwhile for Americans to watch it now, because the same lies and greed for power is eating away at our own country from within. Any honest open-minded viewing of this mid-20th century history cannot help but see the parallels.

I should add that Capra knew how to make movies, and he made sure this history was told in a riveting and compelling manner. You will not be bored.

Blue Origin-led team bids for NASA manned lunar lander contract

11:09 am

Capitalism in space: Though few details have been released, Blue Origin has teamed up with Boeing and Lockheed Martin to bid for a NASA contract to build a second manned lunar lander, after SpaceX’s Starship.

Blue Origin revealed its team’s submission to that second NASA program in a brief statement posted on its website on Tuesday, saying “in partnership with NASA, this team will achieve sustained presence on the Moon.”

The deadline for proposals was Tuesday. NASA is expected to make an award decision in June 2023.

Blue Origin’s team also includes spacecraft software firm Draper, Pittsburgh, Pennsylvania-based Astrobotic and Honeybee Robotics, a manufacturer of military and civil robotic systems that was acquired by Blue Origin in January.

It will be interesting to see if this proposed lander is significantly different than the previous proposal, which NASA considered overpriced and not as capable as Starship.

Virgin Orbit schedules launch from the UK, despite no permit

11:01 am

Virgin Orbit has now scheduled its first launch from a Cornwall airport for December 14, 2022, even though the company has not been issued its launch permit from the Civil Aviation Authority (CAA) of the United Kingdom, even after almost six months of delays.

Spaceport Cornwall was awarded an operators licence by the Civil Aviation Authority (CAA) last month, meaning the site is licensed for launch operations.

However, Virgin Orbit as the operator needs both launch and range licences from the CAA before the historic launch can happen. Spaceport Cornwall told MailOnline that December 14 is when the window opens for the first launch attempt – although this is ‘by no means a guaranteed flight date’.

According to a BBC report, that license has still not been issued. I suspect Virgin Orbit has set this date to pressure the CAA to finally get its act together and issue the permit.

The Middle East in Space

9:21 am

A space conference taking place this week in the United Arab Emirates has produced a number of somewhat intriguing stories, some indicating the growing the new colonial movement in space, and some marking the significant changes produced by the Abraham Accords, peace treaties negotiated and signed during the Trump administration between Israel and a number of Arab nations.

For example, Israel’s president, Isaac Herzog, was invited to the conference to give a keynote speech, and he did so as part of a tour of several Arab countries, all of whom were Israel’s sworn enemies prior to the Abraham Accords.

In his address, Herzog touted Israel’s warming ties with Bahrain and the Emirates since the signing of the Abraham Accords in 2020, and predicted a leap forward in space exploration. “I am very happy to be here and take part in this timely debate, under the auspices of my dear friend, President Mohammed bin Zayed. I have just arrived from Bahrain with my wife, Michal, where we conducted the first State Visit of an Israeli president in the Kingdom of Bahrain, and I am extremely grateful to His Majesty the King of Bahrain, Hamad bin Isa Al Khalifa.”

It appears that, even though the Biden administration has done little to promote further Abraham Accord agreements, many powerful Arab nations of the Middle East are embracing these deals regardless, and thus the tensions in that war-torn region have been largely reduced as a result. Israel still has enemies there, but it now appears to have, at a minimum, neutral partners willing to peacefully work with it.

The conference has also produced additional space news from other Middle East countries.

Ukrainian rocket startup targets ’23 for first launch

8:57 am

The new colonial movement: A Ukrainian rocket startup, Promin Aerospace, now expects to complete the first suborbital launch of a test rocket in 2023, despite the Russian invasion and its regular bombing the city of Dnipro, where the company is based.

On Feb. 22, two days before the Russian invasion, Rudominski sent the first batch of emails seeking seed investment. When the war started, Promin executives realized their investment plans would need to be put on hold while their focus shifted to the safety of employees, families and friends, plus support for Ukrainian defense and humanitarian relief efforts.

By early April, most employees were back working full time.

The company does not reveal its location out of fear of further Russian bombing.

As for its planned rocket launch, though it wishes to do the test from the Ukraine, it also has a deal with one of the new spaceports in Scotland and could launch from there if necessary.

Rogozin returns, playing a soldier in the Ukraine!

1:06 pm

Dmitry Rogozin, about to go into battle!
Dmitry Rogozin, about to go into battle!

Fired from his job as head of Roscosmos and exiled to the Ukraine, Dmitry Rogozin has returned to the news! He was recently interviewed on Russian television, during which the broadcast showed clips of Rogozin getting a tour from Russian troops.

The screen capture to the left show Rogozin during that tour, dressed in military gear, though most of that gear is apparently Western in make, not Russian. Go Dmitry!

According to Antoly Zak, Rogozin during the interview promised that Russia will soon occupy Kiev, Vienna, Berlin and Budapest. As I say, go Dmitry!

Since Rogozin was sent to the Ukraine in July his work there has mirrored his “successes” at Roscosmos. At Roscosmos he was instrumental in ending Russia’s deal with OneWeb, costing Putin several billion dollars in launch income while destroying any chance for years of Russia getting any international rocket business. In the four-plus months since he arrived in the Ukraine, Russia has been on a steady retreat, losing vast areas it had previously conquered.

Hat tip to BtB’s stringer Jay, who says of Rogozin, “This guy is worse than Baghdad Bob!”

SpaceX postpones launch of Ispace’s Hakuto-R lunar lander

8:40 pm

SpaceX tonight canceled the Falcon 9 launch of the private Hakuto-R lunar lander, built by the Japanese company Ispace and carrying the UAE’s Rashid rover.

After further inspections of the launch vehicle and data review, SpaceX is standing down from Falcon 9’s launch of ispace’s HAKUTO-R Mission 1 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. A new target launch date will be shared once confirmed.

The first stage had flown four times previously. Apparently during their standard dress rehearsal countdown and fueling before launch they detected something that cannot be immediately resolved.

Musk’s success vs Trump’s failure

1:34 pm

Elon Musk arrives at Twitter
Musk arrives at Twitter, ready to clean house

While the buzz about Elon Musk’s takeover of Twitter has mostly focused on his effort to end censorship and the banning of conservatives, none of this constitutes his most important accomplishment there.

Yes, mandating freedom of speech at Twitter is a good thing. And yes, ending the banning of tens of thousands of conservative voices demonstrates Musk’s unwavering commitment to freedom and open debate.

However, it is his action to house-clean — to fearlessly remove from power the thugs and goons at Twitter who created these oppressive policies — that matters the most. By firing the Twitter apparatchiks who had installed that system of censorship and blacklisting, Musk has guaranteed that this censorship and blacklisting will not return easily to Twitter should his other business interests force him to pay less attention in the future.

NASA awards construction company $57 million development contract for lunar construction

9:00 am

Capitalism in space: NASA today awarded a $57 million development contract to ICON, a Texas-based company that specializes in building 3D-printed homes on Earth, to begin work on designing habitats for the Moon.

As noted in this report:

The newly announced NASA contract, granted via the agency’s Small Business Innovation Research program, will help the company mature its tech and procedures. ICON plans to use the money to learn how lunar soil, or regolith, behaves in lunar gravity using simulated samples and real ones brought back by the Apollo missions, company representatives said.

The company will also test its hardware and software on a space mission that simulates lunar gravity. And there will be an even more ambitious trial, if all goes according to plan. “The final deliverable of this contract will be humanity’s first construction on another world, and that is going to be a pretty special achievement,” [CEO Jason] Ballard said in the statement.

ICON has already built a prototype 3D-printed Mars habitat that NASA plans to use to train astronauts for long missions.

SpaceX conducts successful static fire test of Superheavy

3:14 pm

SpaceX today successful completed a 13-second static fire test of its Superheavy first stage booster at Boca Chica, Texas.

I have embedded the video of the test below, cued to just before ignition. The test fired eleven of the booster’s 33 engines, and appeared to go very smoothly.

The company is still moving steadily towards an orbital launch of Superheavy and Starship before the end of the year.

Virgin Orbit’s cash problems continue

9:25 am

Because of endless delays getting a regulatory approval of a launch in the United Kingdom, Virgin Orbit has been unable to complete the 4 to 6 launches in 2022 that it had planned, and is thus experiencing serious cash shortages that has now caused it to cancel plans to sell “additional securities.”

Virgin Orbit reported third quarter revenues of $30.9 million, which exceeded the zero revenues reported in Q3 2021. The company’s net loss was $43.6 million, which was higher than the $38.6 million loss in Q3 2021.

While costs and losses have mounted, Virgin Orbit has experienced delays in increasing its launch rate. The company had planned to conduct four to six launches this year. Today, the total stands at only two with just over a month left in 2022.

Virgin Orbit’s third launch was originally scheduled to take place in last August from Spaceport Cornwall in England. The company is still awaiting a license from the UK government that would allow the launch to take place. It is the first time the government has licensed both an orbital launch and a spaceport, so the process it taking longer than anticipated.

The company had not only ramped up production of its LauncherOne rocket in anticipation of an increased launch rate, it also purchased two more 747s to act as the rocket’s first stage carrier. Those actions however were based on the ability to increase the launch rate, which has been stymied since the summer by Great Britain’s Civil Aviation Authority, which can’t seem to issue permission for Virgin Orbit to launch from a runway in Cornwall.

The canceled sale of securities appears part of the entire investment deal near the end of 2021. The cash shortages and this deal also appear connected to the decision by Richard Branson’s Virgin Group to invest $25 million in Virgin Orbit earlier this month.

Virgin Orbit officials say they intend to double their launch rate in 2023. I suspect that they have to. It is now sink or swim.

Dragon freighter docks with ISS

9:22 am

ISS as of November 28, 2022

Capitalism in space: An unmanned Dragon freighter successfully docked with ISS yesterday, bring with it 7,700 pounds of cargo, including two new solar arrays for the station.

Two International Space Station Roll-Out Solar Arrays, or iROSAs, launched aboard SpaceX’s 22nd commercial resupply mission for the agency and were installed in 2021. These solar panels, which roll out using stored kinetic energy, expand the energy-production capabilities of the space station. The second set launching in the Dragon’s trunk once installed, will be a part of the overall plan to provide a 20% to 30% increase in power for space station research and operations.

These arrays, the second of three packages, will complete the upgrade of half the station’s power channels.

The graphic to the right shows the station as of today, with six different spacecraft docked to six different ports. No wonder there is a significant limit to the number of private missions that can fly to ISS. The needs of the station, as dictated by the international partnership of governments that run it, too often fill those ports.

This limitation will begin changing when Axiom launches its first module for ISS in about two years, followed soon thereafter by the launch of a number of other private independent stations by different American companies.

Rocket startup Agnikul Cosmos opens first commercial launchpad in India

9:09 am

Capitalism in space: The Indian rocket startup Agnikul Cosmos has completed construction on the first privately owned launchpad in India, with the first suborbital launch planned before the end of this year.

Agnikul’s infrastructure comprises a launchpad and a Mission Control center 4 kilometres away, both within ISRO’s facilities on the island located off the coast of Chennai. The space pad was designed by Agnikul, constructed over two months, and is a part of the MoU signed between ISRO and Agnikul (among other space startups) under the new regulatory authority IN-SPACe’s first batch of support projects for private companies from ISRO.

Currently, it is capable of launching Agnikul’s rocket, the Agnibaan. [emphasis mine]

The first test launch is apparently not going to be orbital, but a technology test of the launch pad, its fueling facilities, and the 3D-printed engine Agnikul has built for Agnibaan.

The highlighted words once again note the effort by the Indian government to emulate the U.S. policy in the past decade to transition from a government-run space program to a privately-run competing and chaotic space industry. This MoU (memorandum of understanding) probably resembles the first space act agreements NASA issued to SpaceX and Orbital ATK. The agreements gave private companies aid and assistance, but the companies retained full ownership of what they build, and were left free to design things as they saw fit, not as the government dictated.

That two different Indian companies, Agnikul and Skyroot, are on the verge of their first orbital launches signals that this policy is succeeding. Agnikul has tested its engines and built its launchpad. Skyroot has completed its first suborbital launch.

SpaceX’s Falcon 9 successfully launches Dragon freighter to ISS

12:34 pm

SpaceX today successfully used its Falcon 9 rocket to launch a Dragon freighter to ISS.

The first stage landed successfully on a drone ship in the Atlantic, completing its first flight, only the third time this year out of 54 total launches that SpaceX had to use a new first stage. All other launches were with reused boosters.

The Dragon freighter is scheduled to dock with ISS at 7:30 am (Eastern) tomorrow.

The leaders in the 2022 launch race:

54 SpaceX
52 China
19 Russia

Smallsat rocket startup Phantom Space gets NASA launch contract

8:32 am

The smallsat rocket startup Phantom Space has been awarded a NASA launch contract designed to encourage new companies.

Phantom Space Corp. announced today it has been awarded four new NASA task orders to launch CubeSat satellites into space as part of the new VADR contract. NASA’s VADR missions (for Venture-class Acquisition of Dedicated and Rideshare) missions intend to meet the agency’s needs for NASA payloads while also fostering the development of new launch vehicles from both emerging and established launch providers. VADR increases access to space by significantly reducing costs using less NASA oversight to achieve lower launch costs with payloads that can accept a higher risk tolerance.

…The company plans to stage the first space flights in 2024, and the NASA CubeSats will be among the first payloads. Two will be onboard the second Phantom flight, and the other two will be on the fourth flight. The CubeSat launches for NASA will occur at the Vandenberg Space Force Base’s Space Launch Complex 8.

The Tucson-based company’s Daytona rocket will use ten Hadley engines being built by the rocket engine startup Ursa Major.

One of Phantom’s founders, Jim Cantrell, gave me a tour of their facility in May. Cantrell had been head of the rocket startup Vector, and when that failed because its own engines were underpowered, formed Phantom. Phantom however does not build its own engines but gets them from Ursa Major, a company founded by former SpaceX engineeers.

ESA commits more than $100 million to encouraging private space companies

9:42 am

Capitalism in space: The governmental officials representing all of the partners in the European Space Agency this week decided to commit $122 million to a program designed to encourage private independent and competing space companies.

This budget represented a 17% increase.

The ScaleUp programme, which has two elements, supports a company along its entire life cycle. First, it assists in the development of the enterprise with business incubation, business acceleration, intellectual property and technology transfer services (ScaleUp Innovate), and then, it facilitates the scaling up of their products on new markets (ScaleUp Invest).

ScaleUp is business-focused and not technology or sector specific and applies within all ESA programmes. This programme targets start-up companies, applied research and innovation centres, and more mature companies such as SMEs, Mid-Caps and large system integrators.

While encouraging news, the language of the press release and the size of the budget indicates that these European governments are being dragged kicking and screaming into this new capitalist aerospace world. It is clear that ESA has been losing out by sticking with its government-run and government-owned Arianespace operation. At the same time, it is also clear that ESA officials and their governments are showing the same reluctance Congress showed in the last decade when NASA wanted to transition from its government-run and -owned system. At that time, Congress consistently resisted budgeting the commercial space line in NASA’s budget, thus delaying the launch of both Dragon and Starliner significantly.

In the end the effectiveness of competition, private property, and freedom however won out in the U.S. I expect it will do the same in Europe, though it might take another decade or so before Europe’s governments realize it.

Launch of Ispace’s Hakuto-R lunar lander delayed two days

9:28 am

Ispace yesterday announced that the launch of its Hakuto-R lunar lander, carrying a number of private and government payloads including the UAE’s Rashid rover, has been delayed two days to November 30, 2022 due to weather and scheduling issues.

The spacecraft will be launched from Cape Canaveral on a Falcon 9 rocket. The weather and the Thanksgiving holiday forced NASA and SpaceX to push back the launch of a cargo Dragon to ISS to November 26th. This in turn impacted Hakuto-R’s launch date.

Rocket Lab wins launch contract abandoned by Astra

10:32 am

NASA yesterday awarded Rocket Lab the contract to put its constellation of TROPICS satellites into orbit, on two different launches.

This contract replaces Astra as the launch provider, which has abandoned launches while it develops a new rocket.

Astra’s contract, valued at $7.95 million, was for three launches on its Rocket 3.3 vehicle – a rocket that Astra later announced would be discontinued, in favor of a larger and more powerful Rocket 4.

But Rocket 4 is still under development – and may not be ready to launch until 2024. NASA decided not to wait that long, and said in September that it would modify the TROPICS launch contract with Astra for “comparable scientific payloads” on the new rocket.

Moreover, the launches will occur at Wallops Island, strengthening Rocket Lab’s presence there. The company will attempt its first launch there in early December, a launch delayed for two years because of holdups created by NASA’s bureaucracy. With this new contract, NASA’s management will now have an incentive to speed use of Wallops by Rocket Lab, not slow it down.

Hungary to pay $100 million to Axiom for astronaut mission to ISS

12:35 pm

Hungary has budgeted $100 million to fly a Hungarian astronaut on a 30 day mission to ISS, arranged as a private mission though the American space company Axiom.

“This is a program which is being carried out with the cooperation of the American company Axiom Space and its extent is $100 million,” said [Péter Szijjártó, Hungarian foreign minister,] of the initiative. “This will end up in a 30-day-long research mission of a Hungarian astronaut with three other astronauts at the end of 2024 or beginning of 2025, depending on what time NASA confirms access to the International Space Station.”

NASA has yet to award missions to Axiom Space beyond its Ax-2 mission scheduled for the spring of 2023, but is evaluating proposals for two private astronaut missions that could include an Axiom Space flight in that timeframe.

It is clear that negotiations for arranging this mission between Axiom, NASA, and Hungary are on-going. Based on Szijjártó’s description, it is possible that the Hungarian astronaut could fly on a dedicated private Axiom mission to ISS, with two other paying passengers and an Axiom commander, or fly as an extra passenger on a normal ISS crew rotation flight. Furthermore, the ’24 or ’25 launch date suggests the vehicle might not be a Dragon capsule. By that time Boeing’s Starliner should be operational, thus giving Axiom and NASA an alternative. That time frame also corresponds to about when Axiom hopes to launch and dock its own module to ISS.

Nor is Hungary the only foreign country that has signed a deal with Axiom for a manned flight. Both Turkey and Saudi Arabia have agreements as well.

All told, the biggest obstacle right now to this new market is the number of ports on ISS. It seems Axiom has a strong incentive to get its own module launched and attached to ISS as soon as possible, if only to increase the docking ports available for these flights.

First commercial passenger spacewalk on Dragon will involve depressurizing entire spacecraft

9:12 am

According to an interview to Space.com by the four crew members on next year’s private manned Dragon flight financed by Jared Isaacman, the spacewalk, the first involving commercial passengers, will include all four passengers, since Dragon will not have an airlock and will be depressurized entirely when the hatch opens.

“We’ve collectively taken the position that we’re all going for an EVA,” Isaacman said, adding that the spacecraft cabin is to be depressurized in a hard vacuum. “Whether you’re sticking your head outside, you are doing an EVA. We are contemplating two people on the outside of the vehicle,” Isaacman said, “and two would be inside making sure that everything is going correct.”

To accommodate the spacewalk, this Crew Dragon will not be outfitted with a transparent dome, as was the case for the Inspiration4 mission.

The mission is presenting targeting March ’23 for launch.

SpaceX successfully launches communications satellite for Eutelsat

8:06 pm

SpaceX tonight successfully launched a geosynchronous communications satellite for Eutelsat. This was the third launch that SpaceX has done for this European company, which previously had traditionally been launched by Arianespace. Because of the delays and higher cost to use Arianespace’s new Ariane 6 rocket, the company chose to go with SpaceX instead.

The first stage, which had flown ten times previously, successfully completed its eleventh flight, but was not recovered because all of its fuel was needed to get the satellite to its proper orbit.

The leaders in the 2022 launch race:

53 SpaceX
52 China

CAPSTONE enters its planned lunar orbit

9:21 am

After experiencing serious tumbling shortly after launch, engineers have successfully put the technology test smallsat CAPSTONE into its planned lunar orbit (the same to be used by NASA’s Lunar Gateway space station), where it will spend at least six months gathering data.

In addition to studying this unique orbit, CAPSTONE’s mission also includes two technology demonstrations that could be used by future spacecraft. The Cislunar Autonomous Positioning System, or CAPS, is a navigational software developed by Advanced Space that would allow spacecraft operating near the Moon to determine their position in space without relying exclusively on tracking from Earth. CAPSTONE will demonstrate this technology by communicating directly with NASA’s Lunar Reconnaissance Orbiter, which has been in orbit around the Moon since 2009. CAPSTONE will also demonstrate one-way ranging using a chip-scale atomic clock, which could allow spacecraft to determine their position in space without the need for a dedicated downlink to ground stations.

CAPSTONE is also demonstrating a third technology as well as the use of capitalism in space. The third technology is demonstrating the viability of using a tiny inexpensive smallsat for these kinds of interplanetary missions. The capitalism is that CAPSTONE was built by a private company, Terran Orbital, not NASA, and is being operated by another private company, Advanced Space, not NASA. It was also launched by a private company, Rocket Lab, not NASA. All three have proved or are proving that it is faster and cheaper for the government to merely act as the customer to private enterprise, rather than being the builder/operator and boss.

ABL’s RS1 rocket has another abort at launch

9:10 am

In making its third attempt to launch its first RS1 rocket, ABL engineers experienced their second abort at T-0, with the rocket shutting down just as its engines ignited.

The first attempt on Monday, Nov. 14, was scrubbed due to off-nominal data on the first stage during propellant loading. A second attempt on Thursday, Nov. 17, was aborted due to turbopump oxygen inlet conditions at engine ignition. The most recent attempt on Monday, Nov. 21, was aborted during engine ignition at T-1.75 seconds.

The company is now targeting December 7th for their fourth launch attempt. The rocket carries two customer cubesats, but its main mission is to demonstrate its ability to reach orbit.

Pushback: Court orders school board to stop censoring and banning parents

1:26 pm

The Forsyth County School Board

Bring a gun to a knife fight: In a victory for free speech, a federal judge has ruled that the censorship and banning of some parents by the Forsyth County Board of Education in Georgia was unconstitutional, and must cease immediately.

This is a follow-up of a previous blacklist story from back in August, when those parents sued the board because it would not permit them to speak at board meetings during public comment about the pornography the board was allowing in schools.

Multiple district residents, including Mama Bears members and plaintiffs in the lawsuit Alison Hair and Cindy Martin, have used their time to read aloud from school library books they consider pornographic. Yet while these materials are available to kids in school, the Chair has cut off and banned speakers who read from them at Board meetings when he deems the language inappropriate or profane.

LightSail-2 completes three-plus year mission, burning up in atmosphere

9:44 am

LightSail-2 sail deployed
LightSail-2, shortly after deployment in 2019.

LightSail-2, an experimental solar sail built by the Planetary Society, finally ended its mission this week, with the test sail burning up in the atmosphere upon re-entry.

LightSail 2 was launched aboard a SpaceX Falcon Heavy rocket in June 2019, settling into an initial orbit at an altitude of around 720 km (450 miles). At that height, the Earth’s atmosphere is still thick enough to create drag, which would threaten to eventually pull the spacecraft down.

But that’s where the plucky little satellite’s special ability came in. Although it’s only the size of a shoebox, LightSail 2 unfurled a big reflective sheet, called a solar sail, about the size of a boxing ring. The idea is that photons from sunlight strike this sail and generate tiny amounts of thrust, allowing the craft to change its orbit.

And LightSail 2 demonstrated this concept beautifully. In three and a half years, the spacecraft completed around 18,000 orbits and traveled 8 million km (5 million miles), adjusting its orbit continuously to keep itself aloft. But all good things must come to an end, and sometime on November 17, drag finally won the tug-of-war and pulled the spacecraft back to Earth.

LightSail-2 was the third time a light sail had been flown in space, with the first, Ikaros, deployed by the Japanese in 2010 and flown in solar orbit through 2012. That mission was successful in using sunlight to accelerate the sail. This was followed by LightSail-1 in 2015. That mission has some communications problems, but eventually succeeded in its main engineering mission by testing the sail deployment system.

SpaceX cancels launch after reviewing static fire test data

9:06 am

After a review of the test data produced during its standard dress rehearsal countdown and static fire prior to launch, SpaceX decided to cancel a Falcon 9 launch yesterday, carrying 52 Starlink satellites.

The first stage booster had previously launched 10 times, though it is not clear if this is the cause of the delay.

It’s not the first time SpaceX has delayed a launch indefinitely after a static fire test, but it is the first time in years. SpaceX semi-regularly stands down from launch attempts to conduct inspections or complete minor repairs or component replacements when data is amiss or contradictory, but those plans tend to mention the next launch target. This time, even SpaceX’s website has been scrubbed to say that “a new target launch date [will be announced] once confirmed.”

The last time a prelaunch static fire was explicitly blamed for a launch delay was in August 2019, when SpaceX fired up a Falcon 9 rocket ahead of its Amos-17 launch, didn’t like what it saw, decided to replace a valve on the booster, and then conducted a second static fire test to clear the rocket to launch. It’s possible that Starlink 2-4’s sequence of events will end up being similar.
