Chandrayaan-2 successfully puts itself in route to the Moon

8:46 am

Chandrayaan-2 today successfully completed its last Earth perigee burn, raising its orbital apogee so that it will enter the Moon’s gravitational sphere of influence on August 20th.

Chandrayaan-2 will approach Moon on August 20, 2019 and the spacecraft’s liquid engine will be fired again to insert the spacecraft into a lunar orbit. Following this, there will be further four orbit maneuvers to make the spacecraft enter into its final orbit passing over the lunar poles at a distance of about 100 km from the Moon’s surface.

…Subsequently, Vikram lander will separate from the orbiter on September 02, 2019. Two orbit maneuvers will be performed on the lander before the initiation of powered descent to make a soft landing on the lunar surface on September 07, 2019.

Vikram will be doing the hardest part, the landing.

NASA extends life of private BEAM module

9:39 am

Capitalism in space: Having found that Bigelow’s privately built ISS module BEAM has exceeded its design capabilities, NASA has now decided to leave it docked to ISS for at least five more years, using it as a storage bin.

BEAM cost NASA a whopping $17 million, considerably less than it has traditionally spent (a billion-plus) for its previous ISS modules, designed and built under full NASA supervision.

Linkspace completes vertical take-off and landing test

9:29 am

China’s semi-private company Linkspace on August 9 successfully completed its highest vertical take-off and landing test flight yet, flying to a height of 300 meters.

The 8.1-meter-tall, 0.65-meter-diameter, 1.5-metric-ton rocket reached an altitude of 300.2 meters during its 50-second flight before making a powered descent and vertical landing with an accuracy of 0.07 meters, Linkspace CEO Hu Zhenyu stated on Sina Weibo, a Chinese Twitter-like service. The launch follows two tests reaching 20 and 40 meters in March and April respectively.

The latest test was carried out at a new facility in the Lenghu region of Qinghai province in the northwest of the country. Chinese magazine Future Aerospace states that the RLV-T5 is powered by five variable-thrust rocket engines which use ethanol and liquid oxygen, a propellant combination used by the German V2 rockets.

Unlike the other new semi-private Chinese commercial companies, Linkspace appears to be using liquid fueled rockets, rather than depending on military solid rocket technology. This suggests to me that this company, aggressively supervised by the Chinese government, will eventually be going for both the small and big orbital business, not just smallsats.

I also give credit to the Chinese, both their government and this company, for quickly facing reality posed by SpaceX’s capabilities and working to develop their own rocket reusability as fast as possible. In contrast, Europe, Russia, and the old American big rocket companies have mostly sat twiddling their thumbs, making believe that this capability is either irrelevant, or still impossible, even as SpaceX has taken all of their business because it can undercut their prices significantly as it repeatedly re-uses its Falcon 9 first stages.

Blue Origin protests Air Force launch procurement process

9:12 am

Blue Origin has submitted a protest to the Government Accountability Office (GAO) yesterday about the Air Force plan to pick two launch providers now for all its satellite launches after 2026.

According to a copy of the protest obtained by FLORIDA TODAY, the ordering period for the launches would run from 2020 to 2024 and ultimately select two contractors for flights beginning in 2026.

“The most recent market research, however, indicates the total global addressable space launch market, including NSSL launches, could support three or even four U.S. launch companies,” the protest reads. “Even the Agency’s own LSP source selection support contractor – the Aerospace Corporation – predicts that the space launch market has significant potential to suffer from a launch capacity shortfall because U.S. and foreign government launches will require most of the available launch capacity.”

I couldn’t agree with Blue Origin more. The Air Force wants to limit competition in the 2020s to only two companies, which will almost certainly be ULA and SpaceX since they are the only two presently flying, when by the 2020s there might be several more companies available providing competition that can lower the price.

There is no reason for the Air Force to make this decision now. None. When they need to order these launches in the early 2020s they should open that bidding process to all comers, and pick appropriately, then. Everything about this Pentagon plan stinks, reeking of the corruption that permeates Washington. I even wonder if some people have gotten pay-offs in connection with the decision to favor only two companies. It wouldn’t surprise me. (I myself have been offered money to let military lobbying companies ghostwrite op-eds using my name, supporting this Air Force plan, offers that I very bluntly turned down.)

Also, even if Blue Origin’s protest now fails, expect whoever doesn’t get picked by the Air Force now to file lawsuits in the 2020s when they are denied the right to bid on those future launches. And expect the Air Force to then back down, as it was forced to do when SpaceX was denied the right to bid on Air Force contracts early in this decade.

One more thought: This protest suggests Blue Origin already expects to not get picked. This expectation might also explain why Jeff Bezos decided to sell more Amazon stock last week, raising almost $3 billion in capital. He might be anticipating that Blue Origin will be cut out of those Air Force contracts, and so needs more of his own money to develop its New Glenn rocket.

Reports of another ExoMars parachute failure during test

9:09 am

Following a failure of ExoMars’ parachutes during a May test, there are now reports that a second failure occurred on August 5.

A fresh test of the parachute system for the Russian-European mission ExoMars-2020 have failed again as a structural mockup of the Russian-built lander crashed during the simulated landing, a source familiar with the test results told Sputnik.

The test with the use of a high-altitude balloon was carried out on August 5 at a Swedish Space Corporation’s test site in northern Sweden.

“Tests of the parachute system at the Esrange test site in Sweden failed. A full-size mockup of the landing module of the ExoMars-2020 Martian station crashed during the landing,” the source said.

I have seen this report in two other sites, but it has not yet been confirmed by the European Space Agency.

If these reports are true, the chances of ExoMars launching in July 2020 is likely almost nil. They haven’t even begun assembling the spacecraft, and have had two parachute failures in tests, with the second destroying the prototype used for those tests.

Vector changes CEO, might have money issues

5:39 pm

Capitalism in space: Jim Cantrell, who had been the CEO of smallsat rocket company Vector Launch since inception, has apparently left the company.

Vector, a micro-launch company founded in 2016 to build small rockets for payloads of up to 60kg, may be in financial trouble, multiple industry sources told Ars on Friday. A spokeswoman for Vector did not comment on that. However, she did confirm the company has parted ways with its chief executive: “Jim Cantrell is no longer with Vector effective today. John Garvey has assumed the role of CEO.”

I wish this story wasn’t so, though I also admit my instincts were telling me things were going sour with the continuing delays in their test launch schedule.

Jim Cantrell was an unusual CEO, always available and open. He generously took me on personal tours of Vector facilities, twice, first in March 2017 and again in January 2019. I wish him well in whatever future endeavors he undetakes.

As for Vector, they need to get off the ground. They had had a substantial head start over many of the other new smallsat rocket companies, but that lead has now evaporated.

More information here. It appears one of their major investors might have pulled out. It also appears they have temporarily suspended operations, shuttering their offices.

OneWeb: LauncherOne too expensive

8:30 am

In asking that Virgin Orbit’s lawsuit against internet satellite manufacturer OneWeb be dismissed, OneWeb has claimed that their contract allowed for the cancellation of launches without cause, and that they have a cause anyway, which is that LauncherOne is too pricey.

In its court filing, OneWeb said the $6 million price tag for a LauncherOne mission is two to three times current market prices.

…The original contract, OneWeb claims, allowed for termination without cause, and for prior payments to apply to the termination fee. Those contract termination rules, and the fact that Virgin Orbit has yet to conduct any LauncherOne missions, invalidate Virgin Orbit’s revenue expectations, according to OneWeb. [emphasis mine]

Based on my estimate of the launch market, LauncherOne’s price is higher than others, but not by very much. I think the highlighted text is more significant. LauncherOne had announced plans to fly its first mission last summer. More than a year later that inaugural flight has still not taken place.

In the meantime, this decision by OneWeb is a boon to Russia’s space industry, especially its Soyuz rocket, as it will now get the contracts for launching the majority of OneWeb’s 648-satellite constellation.

FCC streamlines and cuts fees for smallsat licensing

9:09 am

Capitalism in space: In an effort to ease its bureaucratic obstacles to private enterprise, the FCC has streamlined its licensing process for new smallsats, while cutting its licensing fees by more than 90%.

Under the optional licensing regime, which stands to take effect this year, smallsat operators with spacecraft that meet certain criteria will be able to obtain a spectrum license about twice as fast and pay only $30,000 instead of nearly $500,000. A maximum of 10 satellites at a time can be licensed under the streamline process.

…Operators will be able to use the streamlined licensing for satellites that weigh 180 kilograms or less, operate below 600 kilometers (or have propulsion) and will deorbit within six years, among other criteria.

One component of these new regulations is that they require new smallsats to never be smaller than 10 centimeters on their smallest dimension, thus essentially forbidding the launch of nanosats smaller than that.

Video of Long March 2C grid fins used in July

9:01 am

China Central Television has released a very short video showing the grid fins used during the July 26 launch of China’s Long March 2C rocket in order to better control the descent of that rocket’s expendable first stage.

I have embedded the video below the fold. It shows the four grid fins unfolding, but not much else. It also reveals that the Chinese very clearly were inspired by SpaceX’s Falcon 9 grid fin design.

The video also gives me the impression that the Long March 2C first stage does not have any thrusters, which were SpaceX’s primary mode for controlling its first stages, the grid fins added later when they understood better the engineering required. Thus I suspect that the fins were not very successful in controlling that stage’s flight.

Nonetheless, the Chinese are doing these tests during operations, which means they are only a first step on a path to success.

Vector gets Air Force launch contract

8:50 am

Capitalism in space: Vector has signed its first Air Force launch contract for an orbital cubesat launch in 2021.

The Air Force must know something about Vector’s rocket development that we don’t. The company had planned a suborbital test launch for March/April, delayed it until June, and has still not flown it. These delays put the company behind its original launch schedule by a considerable amount, which originally had called for its first orbital launch in 2018.

Hopefully we shall soon see some actually progress from Vector. At the moment however their lack of launches has allowed a number of other smallsat rocket companies to gain on them from behind.

Yutu-2 and Chang’e-4 go to sleep again

8:42 am

Yutu-2's travels

Both Yutu-2 and Chang’e-4 have been put in dormant mode after completing their eighth lunar day on the far side of the Moon.

The article at the link provides a lot of new details about what both spacecraft have learned and done since they landed, including a nice detailed map showing Yutu-2’s exact path during those eight lunar days. The image to the right, reduced to post here, was taken by Yutu-2, and shows the rover’s tracks during what appears to be its seventh lunar day. It appears that the rover periodically stopped and did a pirouette, probably to obtain a 360 degree mosaic of the surrounding terrain.

Yutu-2’s travels have tended west from Chang’e-4, and on its eighth lunar day it continues that route, traveling 271 meters. After a period of short traveling days, they have now upped the distance traversed by a considerable amount. Since the planned nominal mission for both spacecraft had been three lunar days, both are demonstrating that the Chinese have figured out how to do this, and are now pushing Yutu-2 hard as a result.

The article vaguely describes some of the science obtained so far, but in general the Chinese remain tight-lipped about most of their discoveries.

ULA’s Atlas 5 launches military communications satellite

8:07 am

Early this morning ULA used its Atlas 5 rocket to successfully launch an Air Force military communications satellite.

This was the third ULA launch this year, which means they remain off the leader board below. This number of launches is also below the pace set the last two years, where they completed eight launches per year.

The leaders in the 2019 launch race:

12 Russia
11 China
10 SpaceX
6 Europe (Arianespace)
4 India

The U.S. now leads in the national rankings 17 to 12.

Smallsat rocket company Orbex signs two launch deals

1:05 pm

Capitalism in space: The new smallsat rocket company Orbex today announced the signing of two different launch deals, one with In-Space and the other with Innovative Space Logistics both with companies focused on procuring launch services for smallsat companies.

Both are for its as yet untested Prime rocket, which they hope to launch by 2021 from the United Kingdom’s new spaceport in Scotland.

Cygnus undocks from ISS, will remain in orbit for five more months

10:55 am

Northrop Grumman’s Cygnus cargo capsule has undocked from ISS, but will remain in orbit until December.

First, the capsule, dubbed the S.S. Roger Chaffee, will deploy a bunch of cubesats and nanosats. Then,

Northrop Grumman plans several months of long-duration spaceflight experiments using the Cygnus spacecraft after release of the CubeSats. Four miniaturized control moment gyroscopes are flying on the cargo freighter for the first time, and engineers will assess their performance in controlling the spacecraft’s pointing without consuming rocket fuel.

Ground teams also want to evaluate how the Cygnus spacecraft’s avionics function on a long-duration mission, and Northrop Grumman plans to demonstrate dual Cygnus operations for the first time after the launch of the company’s next resupply mission — NG-12 — in October.

Northrop Grumman has gotten a NASA contract to use Cygnus as the basis for the habitable module of NASA’s Lunar Gateway project, and this extended flight is a way to test the engineering for that module now during operations.

Though I continue to have many doubts about Gateway, I laud Northrop Grumman for this approach. It speeds things up and saves money.

India’s new smallsat rocket gets its first launch contract

10:48 am

The new colonial movement: India today signed its first customer for its new and still untested SSLV rocket, designed to provide orbital launch services for the burgeoning smallsat market.

Spaceflight announced Aug. 6 that it will purchase the first commercial launch a new Indian vehicle scheduled to make its debut later this year. Spaceflight said it will launch payloads for an undisclosed U.S. satellite constellation customer on a flight of the Small Satellite Launch Vehicle (SSLV), a derivative of the existing, larger Polar Satellite Launch Vehicle (PSLV). The launch is scheduled for later this year and will be the second for the SSLV after a demonstration launch expected no earlier than September.

While the companies didn’t announce the customer for the mission, a July 25 filing with the Federal Communications Commission by Earth imaging company BlackSky Global sought a license for four of its satellites it said would launch on the SSLV in November 2019. The applications said the satellites would be deployed into two orbital planes, consistent with Spaceflight’s announcement.

While this Indian rocket is hardly a private operation, it has no military component, as do the new Chinese smallsat companies. ISRO, India’s space agency, is wholly civilian with no apparent ties to its military, as far as I know. Its goal is to purely make money and grab market share.

At the same time, the use of government funds to develop this rocket gives India the same advantage that China’s smallsat companies have over the privately funded rockets from the U.S. It allows them to set lower prices and undercut the competition.

Rocket Lab to attempt recovery and reuse of Electron 1st stage

10:37 am

Capitalism in space: Faced with stiff competition from both other smallsat rocket companies as well as the big players like SpaceX, Rocket Lab has announced that they are going to try to recover the first stages of their Electron rocket for later reuse.

Their plan is to use the atmosphere and parachutes to slow the stage down as it returns to Earth, and then have a helicopter snag it and land it on a ship.

They had looked into the idea of vertically landing it, like SpaceX does with its Falcon 9, but found it would make their rocket to big and expensive.

This plan is not as radical as it sounds. The Air Force did something similar for almost a decade in the 1960s to recover film from its surveillance satellites.

SpaceX and Arianespace complete successful launches

9:58 pm

Today, as I was giving my lecture in Denver, both Arianespace and SpaceX successfully completed launches.

SpaceX put a commercial communications satellite in orbit. The first stage was not recovered, but this was intended. The company however was successful in catching one half fairing in the giant net of its recovery ship Mrs. Tree., the second time they have done so.

Arianespace used its Ariane 5 rocket to launch a commercial communications satellite and a European Space Agency data relay satellite.

The leaders in the 2019 launch race:

12 Russia
11 China
10 SpaceX
6 Europe (Arianespace)
4 India

The U.S. now leads Russia 16 to 12 in the national rankings.

SpaceX offers new cut-rate prices for smallsats

6:18 am

Capitalism in space: SpaceX yesterday announced that the company is now offering new cut-rate prices to launch smallsats on its rockets.

The company is offering rideshare opportunities for satellites weighing up to 150kg at the price of $2.25 million. The rideshare-only missions, flying aboard the company’s workhorse Falcon 9 rocket, will launch at regularly scheduled intervals. “SpaceX is committed to serving the commercial market as it grows and changes,” a spokesperson for the company said. “And we believe we can address the needs of small satellite operators by offering reliable, cost-effective access to orbit through regularly scheduled, dedicated rideshare missions.”

The company has previously flown rideshare missions using its Falcon 9 rocket, but those flights were organized and integrated by a third-party provider, Spaceflight Industries. Now SpaceX will do all of that work directly for customers

This move makes SpaceX’s smallsat prices very competitive. It also makes it easier for smallsat companies to bypass China’s semi-private commercial companies, thus avoiding the risk of China stealing their technology.

Proton launches military communications satellite

8:44 pm

A Russian Proton rocket today successfully launched a military communications satellite into orbit.

This was the third Proton launch this year, the most since 2017. It also put Russia in the lead for most launches in 2019, the first time that country has been in first since 2015:

12 Russia
11 China
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. still leads Russia in the national rankings, 15-12.

SpaceX to launch Super Heavy/Starship from Florida

8:58 am

Capitalism in space: According to a SpaceX environmental report submitted to NASA, the company now plans to launch Super Heavy/Starship missions from Florida, and only Florida.

The report details the work they want to do at launch complex 39A, where they presently launch both Falcon 9s and Falcon Heavies.

The facilities will be able to support up to 24 Starship/Super Heavy launches a year, the company said in the report, with a corresponding decline in Falcon launches from the complex. “Due to the higher lift capability, Starship/Super Heavy could launch more payloads and reduce the overall launch cadence when compared to Falcon 9 and Falcon Heavy,” the report states.

SpaceX ruled out performing Starship/Super Heavy launches from its other two existing launch sites, Space Launch Complex 40 at Cape Canaveral and Space Launch Complex 4 at Vandenberg Air Force Base in California. The company ruled out the sites because they would require more modifications and because the Vandenberg site didn’t support trajectories for the “vast majority” of missions.

Falcon Heavy launches especially will vanish once this new rocket is operational, as it will be cheaper to use and have greater capabilities, should it succeed in being everything SpaceX hopes it to be.

Bezos provides 1st BE-4 engine update in more than a year

8:49 am

Yesterday Jeff Bezos posted the first status update since last spring on the development of the BE-4 rocket engine by Blue Origin, posting one image and stating that the engine testing continues.

According to his post, the engine had just completed a full power test, and has been accumulating test time.

This update is very reassuring, especially following such a long period of silence, beginning in April 2018. Before that Blue Origin had provided somewhat regularly updates.

In reviewing my past posts, it appears that the updates more or less ceased once ULA announced its decision to use the BE-4 in its Vulcan rocket. I now suspect the earlier updates were aimed more at ULA than the public, and once the decision was made Blue Origin returned to its more traditional tight-lipped approach.

Landowners in Scotland sign lease for spaceport

10:16 am

The new colonial movement: The landowners for a planned commercial spaceport in Sutherland, Scotland, have now signed a 75-year lease with the spaceport developers.

Construction of the project is anticipated to begin next year with the UK Space Agency (UKSA) providing a grant of £2.5million to HIE, as well as funding two launch companies who will use the facility once it is operational.

I highlight the word “UK”, which stands for the United Kingdom, because that word indicates another very big unstated obstacle to this spaceport. The UK as a whole has voted to leave the European Union. The population of Scotland however voted against that exit, and its leaders have indicated that they will not go along with the plans of the new British prime minister, Boris Johnson, to exit, deal or no deal. In fact, they have indicated that they would instead want to leave the United Kingdom in that case.

Should that happen, the future of this spaceport will be threatened. The deals that have made it possible have come from the UK space agency, a entity that Scotland would no longer belong should it leave the United Kingdom.

Chinese test microsat deorbits and crashes into Moon

10:05 am

The new colonial movement: A Chinese tiny smallsat, sent to lunar orbit to test the technology of such microsats, has been deorbited and allowed to crash into the far side of the Moon.

The micro satellite crashed into a predetermined area on the far side of the Moon at 10:20 p.m. on July 31 (Beijing Time), the center said Friday.

Weighing 47 kg, Longjiang-2 was sent into space on May 21, 2018, together with the Chang’e-4 lunar probe’s relay satellite “Queqiao,” and entered the lunar orbit four days later. It operated in orbit for 437 days, exceeding its one-year designed lifespan.

The development of the micro lunar orbiter explores a new low-cost mode of deep space exploration, said the center. The micro satellite carried an ultra-long-wave detector, developed by the National Space Science Center of the Chinese Academy of Sciences, aiming to conduct radio astronomical observation and study solar radiation.

China might be stealing a lot of the space technology it is using to make it a major space power, but it is also doing a fine job of refining and improving that technology. Its capability to do practically anything in space as well if not better than anyone else continues to grow.

And with their government using its space effort as a management test for determining the best individuals to promote into the government’s power structure, do not expect their space effort to wane anytime in the near future.

Chandrayaan-2 successfully completes 4th orbit burn

9:23 am

The new colonial movement: India’s lunar orbiter/lander/rover Chandrayaan-2 today successfully completed its fourth engine burn, this time raising its orbital apogee to 89,472 kilometers (55,595 miles).

The next burn is scheduled for August 6, when the spacecraft’s orbit brings it back down to its perigee.

By September they expect to raise that apogee high enough so that it is within the Moon’s gravitational sphere of influence, when they will be able to put it the spacecraft into lunar orbit.

Bezos sells another $1.8 billion in Amazon stock

10:41 am

Capitalism in space? Jeff Bezos last night sold just under a million shares of his Amazon stock, earning in cash an estimated $1.8 billion.

Unlike a similar sale of stock by Bezos last April, there is no statement from Bezos about what he intends to use the money for. Then Bezos made it clear that he intended to periodically sell his stock to raise money for Blue Origin and its various space ventures. Today’s sale was the third since he said this, with total earnings from all three sales totaling about $4 billion, and all are likely aimed at funding that space company.

I might have increasing concerns about Blue Origin because of what appears to be a stalled rollout of New Shepard and New Glenn, but with deep pockets such as this, it would be surprising if the company fails to achieve its goals.

New NASA development contracts include refueling work by SpaceX

10:26 am

Capitalism in space: Yesterday NASA announced a bunch of partnership agreements with thirteen companies, where those companies will get NASA assistance at no cost to help them develop new engineering that would aid future solar system exploration.

The partnerships covered everything from helping small companies develop new space electronics, heat shields, and new types of thrusters to helping Blue Origin develop the technology for for landing on the Moon.

An article at Ars Technica today about this NASA announcement focused specifically on the SpaceX deal, mainly for its important political implications.

The partnership will have two different NASA agencies helping SpaceX develop the refueling technology it needs for Starship to reach Mars. The key is that this deal has NASA openly supporting technologies that are in direct competition with its own SLS rocket. When such research work was proposed back in 2010, it was opposed quite strongly by past agency officials as well as powerful politicians in Congress, for exactly that reason.

It was a contentious time in space policy, as the White House was pushing for more funding for new space companies—and new space ideas such as fuel-storage depots—while Congress wanted to keep NASA in the rocket-building business.

Eventually, Congress got the upper hand, putting NASA on track to build the large SLS rocket at a development cost of more than $2 billion a year. The rocket program mostly benefited the Alabama space center and was championed by Alabama State Senator Richard Shelby. The potential of in-space fuel storage and transfer threatened the SLS rocket because it would allow NASA to do some exploration missions with smaller and cheaper rockets. As one source explained at the time, “Senator Shelby called NASA and said if he hears one more word about propellant depots he’s going to cancel the Space Technology program.”

The line from other NASA officials was that as a technology, propellant depots were not ready for prime time. In 2011, former NASA Administrator Mike Griffin and current Executive Secretary of the National Space Council Scott Pace—both SLS advocates—wrote a withering criticism of the technology for Space News.

Now however the Trump administration is helping SpaceX develop refueling for Starship, which if successful will help make SLS irrelevant. This is more evidence that the Trump administration is laying the political groundwork that will allow it to shut SLS down, actions that were impossible in the political culture of Washington only two years ago.

This quote in the article is probably the most startling of all:

“Administrator Bridenstine is clearly executing on President’s Trump’s guidance to increase commercial public-private-partnerships at NASA,” Miller, now chief executive of UbiquitiLink, told Ars. “The game-changing technology that NASA has discovered is capitalism. This program proves NASA leadership has figured out the future is reusability mixed with commercial public-private-partnerships.” [emphasis mine]

Imagine that. An American government agency has learned that capitalism is the way to go. Will wonders never cease?

Update: See this related Ars Technica article: The SLS rocket may have curbed development of on-orbit refueling for a decade (Hat tip reader Calvin Dodge.)

Suborbital rocket company has launch failure

9:59 am

Capitalism in space: Gilmour Space Technologies, one of the numerous new rocket companies aimed at capturing the emerging smallsat market, experienced a launch failure on July 29 just prior to lift-off of its suborbital rocket.

At T-7 seconds to launch, the test rocket suffered an anomaly that resulted in the premature end of the mission. Initial investigations show that a pressure regulator in the oxidiser tank had failed to maintain the required pressure, and this caused the upper half of the rocket to be ejected as helium escaped.

On the positive side, there were no explosions due to the safe nature of hybrid rocket engines, and no observable damage to the engine. (The white plume seen here is steam.) Moreover, despite failure to launch, the team did successfully test Gilmour Space’s mobile launch platform and mission control centre, which had journeyed over 1,800 km to the test site.

It appears the failure was from a piece of equipment provided by an outside contractor.

LightSail-2 successfully raises its orbit using sunlight

3:25 pm

Capitalism in space: By raising its orbit by the use of sunlight only, LightSail-2 has confirmed what an earlier Japanese solar sail Ikaros had demonstrated, that it is possible to use solar sails to travel in space.

Since unfurling the spacecraft’s silver solar sail last week, mission managers have been optimizing the way the spacecraft orients itself during solar sailing. After a few tweaks, LightSail 2 began raising its orbit around the Earth. In the past 4 days, the spacecraft has raised its orbital high point, or apogee, by about 2 kilometers. The perigee, or low point of its orbit, has dropped by a similar amount, which is consistent with pre-flight expectations for the effects of atmospheric drag on the spacecraft. The mission team has confirmed the apogee increase can only be attributed to solar sailing, meaning LightSail 2 has successfully completed its primary goal of demonstrating flight by light for CubeSats. [emphasis mine]

The highlighted text notes a secondary but possibly more important engineering achievement here. LightSail-2 was launched as a cubesat. It has now proven that such a cubesat can include a solar sail and use it for purposes of transportation.

Moreover, that this engineering test was funded entirely by private funds proves again that the government is not necessary for great things to be achieved.

They will continue to raise the spacecraft’s apogee for the next month, until the lowering of the perigee causes the spacecraft to get pulled out of orbit by the drag from the atmosphere. That second process will still take about a year.
