Japan and NASA ink lunar deal

9:33 am

After several years of discussion, Japan and NASA have finally signed an lunar exploration agreement whereby Japan will build a pressurized rover that astronauts can use to travel large distances in exchange for NASA launching two Japanese astronauts to the Moon.

An enclosed and pressurized rover will enable astronauts to travel farther and conduct science in geographically diverse areas by serving as a mobile habitat and laboratory for the astronauts to live and work for extended periods of time. It will be able to accommodate two astronauts for up to 30 days as they traverse the area near the lunar South Pole. NASA currently plans to use the pressurized rover on Artemis VII and subsequent missions over an approximate 10-year lifespan.

This rover is being built in a deal between Japan’s space agency JAXA and Toyota. It will be very heavy, which meanst NASA is now planning its lunar exploration with Starship as a fundamental part. No other planned lunar lander could bring this kind of mass to the surface.

The two Japanese astronauts will likely fly on two different Artemis missions over that time-span. When these missions will occur will largely depend on how long NASA stubbornly sticks with is SLS/Orion/Lunar Gateway framework for getting astronauts to the Moon. These assets are not yet ready. They are also very cumbersome and expensive and slow. Missions using SLS expecially cannot occur faster than every two years, if that. If NASA depends on them, serious lunar exploration will likely not occur before 2030, at the earliest.

If however SpaceX’s Starship/Superheavy becomes operational in the next two years, and NASA switches operations to it instead, the pace will pick up, exponentially. Launches could likely occur multiple times per year, and it will be possible to put large amounts of mass on the Moon quickly. That lunar base will be built fast.

The decision to switch however will require a political decision, one that it appears many in Washington are reluctant to make. First, the Democrats now see Elon Musk as an enemy. Why award his company? Secondly, SLS/Orion/Gateway are great jobs programs. Abandoning them will eliminate a lot of wasteful pork, a sin to the politicos who operate our government for their interests, not the interests of the country.

Russia and SpaceX complete launches

9:08 am

Early today both Russia and SpaceX completed rocket launches.

First, Russia after several scrubs for technical reasons successfully completed a test launch of the largest configuration of its Angara rocket, the Angara-A5. It was the first launch of Angara-A5 from its far east spaceport Vostochny, and the first test launch of this rocket confiruration since 2014. Development had stalled for many years due to a major design issue revealed in 2019.

This launch establishes several important benchmarks for Russia’s space program. This rocket is essential for its goal of building a new space station, and the launch from Vostochny gives Russia as stronger backup to Baikonur in Kazakhstan, where long-term access is becoming problematic.

SpaceX then followed, with a launch of a military weather satellite, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its third flight, landing successfully back at Vandenberg.

The leaders in the 2024 launch race:

38 SpaceX
14 China
6 Russia
4 Rocket Lab

American private enterprise still leads the rest of the world combined 44 to 26, while SpaceX by itself still leads the rest of the world, including other American companies, 38 to 32.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Activists file lawsuit to prevent land swap at Boca Chica

2:51 pm

The same collection of activists who have been waging lawfare against SpaceX’s Boca Chica rocket facility have now filed a new lawsuit, this time against the Texas Parks and Wildlife Commission (TPWD) in order to block an approved land swap that gives SpaceX 43 acres of a Boca Chica state park in exchange for receiving 477 acres nearby.

The South Texas Environmental Justice Network, the Carrizo Comecrudo Tribe of Texas, and Save RGV banded together for a lawsuit filed in the District Court of Travis County on April 3. The suit alleges that Texas Parks and Wildlife violated statutory requirements for the proposal, including the requirement to consider alternatives to giving away public park land; the requirement to ensure the minimization of harm to the public park land; and the requirement to consider the best interests of the local community and TPWD.

These jokers represent very few people in south Texas. Worse, the so-called “Carrizo Comecrudo Tribe of Texas” was in Mexico, not Texas, when it existed. The corporation that exists now is a front for filing these lawsuits, taking advantage of the numerous DEI regulations that now exist to favor such minorities.

That the commission approved the swap unanimously, despite heavy pressure from these groups, illustrates the larger support in Texas for what SpaceX is doing. Expect the Texas courts to endorse that support as well. All these suits will do is delay, delay, delay.

Rocket Lab to refly a recovered first stage

2:31 pm

Electron 1st stage floating in the water

Rocket Lab today announced that a first stage used on a launch in January and recovered successfully from the ocean, as shown to the right, has now been moved into its normal production line for preparation for a reflight on an upcoming launch.

The stage was successfully launched and recovered as part of the ‘Four of a Kind’ mission on 31 January 2024 and has already passed more acceptance tests than any other recovered Electron stage, including:

  • Tank pressurization test – a process that filled the carbon composite tank with inert gas and held it in excess of maximum operating pressure for more than 20x longer than the standard Electron flight duration
  • Helium leak check – a stringent process that determines there are no leaks in the tank
  • Carbon fiber structural testing – including ultrasonic assessment and other non-destructive tests to confirm no delamination of the carbon composite tank fibers.

The stage will now undergo final fit out and rigorous qualification and acceptance testing to the same standard as a brand-new Electron tank to determine the recovered stage’s suitability for reflight.

No actual launch date has been set. The company first wants to complete its final testing. If successful and the stage flies again, Rocket Lab will join a very elite club, becoming only the second entity anywhere — after SpaceX capable of reusing a significant part of its rockets. That capability will allow it to drop prices, and better compete.

This success also underlines the lack of creativity from more than a half century of managers and rocket engineers, who repeatedly insisted such reuse was impractical, or impossible. The idea of recovering a stage from the ocean and reusing it was considered crazy, so no one ever tried it. Rocket Lab is about to prove more than a half century of managers and rocket engineers wrong.

Idiocracy has arrived

1:54 pm

Sheila Jackson-Lee:
Sheila Jackson-Lee: “The Moon is made up
mostly of gases!””

Over the last few days the conservative press has been having a field day making justifiable fun of a number of Democrats and leftists for exhibiting incredible scientifict ignorance, an ignorance so profound as to be mind-boggling.

First, after the unusual 4.8 magnitude earthquake centered in New Jersey on April 5th, a Green Party senate candidate in New Jersey, Christina Amira Khalil, immediately tweeted, “I experienced my first earthquake in NJ. We never get earthquakes. The climate crisis is real.” The mocking on X was so great she quickly deleted the tweet.

Then, in an incredibly embarrassing segment of the television show, The View, one host, Sunny Hostin, showed off her complete lack of any scientific knowledge when she claimed that the earthquake, the solar eclipse, and even the normal arrival of the cicadas every seventeen years (which she thought happened every hundred-plus years) was evidence that climate change was real.

Finally, to top off this stream of utter empty-headiness, during an eclipse event in Texas, Congresswoman Sheila Jackson Lee gave a speech of such stunning incompetency and lack of knowledge you have to wonder how she can figure out how to put on her clothes each day. This quote has been most often used to ridicule her:

China successfully tests new propulsion system for satellites

10:01 am

The state-run Chinese press today touted the successful use of a new “cold-propulsion system” on the Tiandu-2 test satellite launched into lunar orbit with its Queqiao-2 relay communications satellite.

The cold propulsion system recently provided high-precision orbital attitude control for the satellite during lunar orbit, marking the first successful application of the liquid ammonia cold air micro-propulsion system in the field of deep-space exploration.

The storage tank is an important component of satellite propulsion systems. As a pressure component, it requires not only high precision of forming and no leakage, but also good anti-fatigue performance, allowing for repeated fuel filling and discharge.

The article touts the tank so much because it was 3D-printed, making it the first such tank sent into space by China.

Angara launch scrubbed for the second day in a row

9:52 am

Technical issues early this morning caused Russia to scrub, for the second day in a row, the first launch of its new Angara-A5 heavy-lift rocket from its Vostochny spaceport in the far east of Russia.

The first attempt to launch the Angara-A5 rocket from the Vostochny spaceport on Tuesday was canceled about two minutes before the scheduled liftoff due to a failure of the pressurization system of the oxidizer tank in the central block [the core stage] of the rocket.

The second attempted launch Wednesday was also aborted by the automatic safety system, which registered a flaw in the engine start control mechanism, said Yuri Borisov, head of Russia’s state-controlled space corporation Roscosmos. He added that the failure was most likely rooted in a programming error.

They intend to try again tomorrow.

Angara has been under development for about two decades. This launch, which carries a dummy payload, will be the fifth launch of Angara, though the first of of the heavy-lift A5 configuration since 2014. In 2019 vibration issues were discovered that caused a major delay in its development. Of the previous four launches, only one carried an actual payload into orbit. All the others carried dummy payloads, with one test launch failing.

Russia needs the Angara-A5 rocket if it is going to build its own space station, because it no longer has the Proton rocket to launch modules. It also needs to get its Vostochny spaceport up and running, because its long term access to Baikonur in Kazakhstan is increasingly questionable.

Japan to sign deal with NASA to fly two Japanese astronauts to Moon

9:34 am

According to story in the Japanese press yesterday, a deal between Japan and NASA will be signed next week whereby Japan will have two astronauts go on Moon missions in exchange for providing cargo to the Lunar Gateway station as well as a manned lunar rover.

The report today is unclear whether those Japanese astronauts will land on the Moon, but I expect they will. The rover project is being led by Toyota. It will include a airtight cabin where spacesuits will not be necessary and passengers can also sleep, allowing for very long exploratory traverses from the landing site.

Reports of this deal have been appearing in the press since 2022, when NASA said it would involve flying one Japanese astronaut to the Moon. In December 2023 it was reported that the deal would be signed within a month. It is now April. It appears the extended negotiations have gotten Japan a second astronaut Moon walker.

NASA’s Artemis program is beginning to shape up as an international program for getting almost everyone to the Moon but Americans. I am exaggerating, but I think in the future Americans will find it easier to go on a private mission to the Moon than depend on NASA, especially because of all the international deals NASA will have to honor.

    • The abort was caused by “a center core oxidizer tank pressurization system anomaly,” according to Roscosmos head Yuri Borisov. You can hear some sound burst at T-2:43, but there is nothing visible, so the sound could simply be some expected venting. They are going to try again tomorrow.

The foot of a Martian glacier

1:00 pm

The foot of a Martian glacier
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on February 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as the “terminus of possible glacier-like feature.” That feature is at the lower left, at the point where glacier-like material appears to be flowing out of the channel from the northeast but then ending in an area of rough fingers.

That this looks exactly like a glacier does not guarantee that it is one, which is why the scientists insert the word “possible.” Nonetheless, the geology resembles that of a glacier, from the parallel lines along its length as well as its existence inside this channel. The location is also at 49 degrees south latitude, well within the mid-latitude strips on Mars where scientists believe many such glaciers exist.

The overview map below adds further weight to this conclusion. It also suggests that there are even more glaciers on Mars than research up to now has suggested.

ULA completes last Delta-4 Heavy launch

10:06 am

Delta-4 Heavy on its last launch
Delta-4 Heavy on its last launch

ULA today successfully completed the last Delta-4 launch, the Delta-4 Heavy version — the most powerful — lifting off from Cape Canaveral and placing a National Reconnaissance Office surveillance satellite into orbit.

From this point on ULA will rely on its new Vulcan-Centaur and Atlas-5 rockets, though production of the Atlas-5 has ceased. When the remaining Atlas-5s are flown, the Vulcan-Centaur in its many iterations will become the company’s mainstay rocket. All this might change depending on who buys ULA. If Blue Origin buys the company, the mix will be more complex, as that company is developing its own New Glenn rocket.

This was ULA’s second launch in 2024, so there is no change to the leader board in the 2024 launch race:

36 SpaceX
14 China
5 Russia

Turkey to join China’s lunar base program

9:02 am

Turkey yesterday announced that it is applying to join China’s program to build a lunar base on the Moon, dubbed the International Lunar Research Station (ILRS), becoming the ninth nation in that partnership.

Those nations are Azerbaijan, Belarus, Egypt, Pakistan, Russia, South Africa, Thailand, Turkey, and Venezuela. In addition, another nine academic organizations of one kind or another have signed on.

Interestingly, Turkey’s government apparently decided to partner with China after it flew its own astronaut on Axiom’s AX-3 mission to ISS in January, flying in a SpaceX Dragon capsule launched by SpaceX’s Falcon 9. Previously it had also signed a deal with Sierra Space to participate in both its Dream Chaser and Orbital Reef station.

This new agreement suggests the present instability of international politics has forced it to go to its very powerful neighbors. Or maybe Turkey is signing on with everyone, attempting to burn the candle at both ends.

New startup to launch a new design for inflatable modules

8:50 am

A new startup, dubbed Max Space, is presently building a test inflatable module it hopes to fly on a SpaceX launch in 2025, testing its new design for inflatable modules that it says is safer and more easily scalable.

Max Space is taking a different technical approach to earlier systems that used a bi-directional “basket weave” fabric structure. “When you start making fibers go in two different directions, 90 degrees apart, the result is you don’t know how much load is going in one direction or the other,” said Maxim de Jong, co-founder and chief technology officer of Max Space, whose past work included development of [Bigelow’s private] Genesis 1 and 2 [orbital modules]. That requires additional material to ensure sufficient margins of safety and also makes it difficult to scale up designs to larger volumes. “Every scale-up is a point design and has to be revalidated,” he said.

Max Space is pursuing a technology called an ultra-high-performance vessel created by de Jong that distributes loads in one direction, a design that he credited to a “totally accidental discovery” while working on other concepts. That reduces the uncertainty in safety margins, which has been demonstrated in tests where modules burst at pressures within 10% of predicted levels. “The predictability is great and the scalability is great,” he said.

According to the company, this design will allow it to quickly build modules with as much as a thousand cubic meters volume, matching ISS in a single module, and able to launch on a single Falcon 9.

The company is not planning its own station. Instead, it simply wishes to be a provider of modules to the other American space stations, four of which are presently being built. It also is offering its modules as potential fuel depots as well as in-orbit storage faciliites.

ESA awards Thales Alenia contract to build Mars lander for Franklin rover

8:40 am

landing site

Click for paper [pdf].

The European Space Agency (ESA) today awarded the Italian company Thales Alenia a €522 million contract to build the entry, descent, and landing module for ESA’s Franklin rover, now scheduled for launch in 2028.

Under this contract, Thales Alenia Space will lead the definition of the Entry, Descent and Landing Module and maintenance activities for the transfer module (carrier) and the rover, including upgrades and replacement of time-sensitive elements. A full audit and tests will be carried out on the rover to ensure its readiness for the new mission. In addition, replacement of some payload elements is planned, such as integration of the new Enfys infrared spectrometer. The batteries and tanks will be replaced on the carrier module as well as potential adjustments to align with the updated trajectories to Mars. New developments on the descent module and landing pad are also required, because the European avionics part of the descent module will be reused.

This contract was necessary because the project was initially a partnership with Russia, whereby Russia provided this lander as well as the launch services. That partnership was severed after Russia invaded the Ukraine, which caused this mission to Mars to be delayed four to six years.

NASA then chipped in $30 million to help pay for launch out of Cape Canaveral, though no launch company has been announced. I suspect both ESA and NASA wish to wait before making a deal, considering how launch costs are dropping. At present it is impossible to predict the landscape of that market in 2028.

What are Israel’s strategic military goals with its latest pull back from Gaza?

12:33 pm

Hamas vs Israel
Even the Arabs recognize these facts.
Courtesy of Doug Ross.

Over the weekend numerous news reports announced that Israel had suddenly pulled almost all its troops out of the Gaza strip, apparently abandoning its plan to finish off the last four battalions of Hamas that were hiding out in the southern town of Rafah.

Despite denials by Israel’s military and the Netanyahu government, on the surface it appeared Israel had bowed to pressure from the Biden administration to cancel its invasion of Rafah and instead break off its military offense against Hamas.

I suspect things are much more complicated, and could instead be — as some Israel officials claimed — a tactical maneuver intended to make that military invasion of Rafah more effective while reducing the large number of civilian deaths anticipated because of the more than a million Gazan refugees that have been crammed into that southern city.

The nature of the withdrawal reveals much about its goal:

A whirlpool half-hidden by dust

A whirlpool half-hidden by dust
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope and shows us a magnificent spiral galaxy about 100 million light years away that also has very active nucleus at its center as well as many star-forming regions (in blue) in its outer arms.

That we do not see the same blue spiral arms on the right side of the photo is not because they are lacking, but because a very large stream of dust blocks our view.

This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of the Milky Way galaxy. The dark clouds in the Chamaeleon region occupy a large area of the southern sky, covering their namesake constellation but also encroaching on nearby constellations, like Apus. The cloud is well-studied for its treasury of young stars, particularly the cloud Cha I, which has been imaged by Hubble and also by the … James Webb Space Telescope.

Lunar Reconnaissance Orbiter snaps a smeared image of South Korea’s Danuri lunar obiter

10:04 am

Danuri as seen by LRO
Click for original image.

Cool image time! On March 5 to March 6, 2024, the orbits of NASA’s Lunar Reconnaissance Orbiter (LRO) and South Korea’s Danuri orbiter had three close approaches, during which LRO had a chance to snap pictures of Danuri as it zipped by in the opposite direction.

The first image is to the right, cropped but expanded to post here.

The flight paths of the two vehicles were nearly parallel but in opposite directions, resulting in extreme relative velocity. The LROC NAC exposure time was very short, only 0.338 milliseconds. But still, Danuri was smeared by a factor greater than 10x in the downtrack direction.

…On the first opportunity, LRO was slewed 43 degrees to capture Danuri from a distance of 5.0 kilometers

Of the three pictures taken, this one appears the best. In all three cases, the fast relative speed was too fast for the camera shutter, so that Danuri’s image was smeared as you see.

Today’s eclipse

9:49 am

The next eclipses to cross the U.S.
Map by Michael Zeiler (GreatAmericanEclipse.com). Click for original.

Today a solar eclipse will cross some of the most populated areas of Mexixo, the United States, and Canada, as shown on the map to the right.

We shall not see such an event in North America again until 2046, and that will only cover a small part of the Pacific northwest. If you have never seen such an event, get your eclipse glasses (essential if you don’t want to go blind), take some time off of work, and go see it today. This link from Sky & Telescope covers about everything you need to know.

The experience is very hard to describe, though I tried when Diane and I traveled to South Bend, Idaho, in 2017 to experience that eclipse. As I wrote,

Totality was amazing. I was amazed by two things. First, how quiet it became. There were about hundred people scattered about the hotel lawn, with dogs and kids playing around. The hotel manager’s husband set up speakers for music and to make announcements, but when totality arrived he played nothing. People stopped talking. A hush fell over everything. Moreover, I think we somehow imagine a subconscious roar from the full sun. Covered as it was, with its soft corona gleaming gently around it, it suddenly seemed still.

Secondly, the amazing unlikeliness of the Moon being at just the right distance and size to periodically cause this event seemed almost miraculous. Watching it happen drove this point home to me. And since eclipses themselves have been a critical event in the intellectual development of humanity, helping to drive learning and our understanding of the universe, it truly makes me wonder at the majesty of it. I do not believe in any particular religion or their rituals (though I consider the Bible, the Old Testament especially, to be a very good manual for creating a good life and society), but I do not deny the existence of a higher power. Something made this place, and set it up in this wonderous way. Today’s eclipse only served to demonstrate this fact to me again.

I am sure your impressions will be unique to you.

Musk provides update to his Boca Chica crew

11:50 am

The candidate landing zone on Mars for Starship
The candidate landing zone on Mars for Starship

Elon Musk yesterday gave a 44-minute update on Starship/Superheavy to his team in Boca Chica, outlining what he now expects in the next two years as well as in the next two decades.

You can watch his presentation here. Musk began by once again describing his fundamental goal behind the company, to make the human race multi-planetary, for its own survival, and that Mars is at this time the best choice for doing so. He then provided some details about the on-going development of Starship/Superheavy:

  • SpaceX will be ready to launch 4th test flight in early May
  • There is an 80-90% chance they will attempt a tower landing of Superheavy, caught by its chopstick arms, by the end of this year
  • Starship will require at least two precision ocean landings before they attempt a tower landing
  • To provide tower redundancy for these test landings, by next year they will have 2 towers at Boca Chica, 2 at Cape Canaveral, with Cape Canaveral operational by next year
  • In 2024 they hope to build 6 Superheavys and Starships for test flights
  • By 2025 they plan to test full refueling of Starship in orbit
  • The third iteration of Starship/Superheavy will be capable of placing 200 tons in orbit
  • That third iteration will cost less to launch than Falcon 1, $2-3 million
  • To make a base on Mars self-sufficient quickly, he anticipates sending large fleets of Starships every two years, everytime the flight window to Mars opens.
  • The preferred landing sites will be in the low mid-latitudes, 30-40 degrees, with elevations two kilometers below the Martian “sea level”, to take advantage of a thick atmosphere.
  • If all goes as planned, Musk expects SpaceX to establish a Mars colony in about two decades

That next-to-last bullet point fits perfectly with the region north of Amazonis Planitia, as shown on the map above, where SpaceX has requested numerous images from the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is two kilometers below the “sea level” of Mars. It is at a latitude either on or close to 40 degrees north latitude. It is a region that orbital data says has lots of very near-surface ice. And it is flat, making those first landings relatively safe.

Argentina demands right to inspect Chinese antenna facility

9:45 pm

The Argentina government of Javier Milei is now demanding the right to inspect a Chinese antenna facility that was established in Argentina in 2014 and began operating in 2017 under a 50-year-lease.

Under the agreement between the two nations, 10% “of the resources in the base must be utilized by Argentina.” However, China has been operating the facility unsupervised from the beginning. Likely built to support China’s space program, manned and planetary, U.S. officials have also suggested it is being used for military purposes, a possibility that cannot be dismissed since all of China’s space program falls under the supervision of the People’s Liberation Army.

Milei apparently wants a hand in its operation, or at least a much clearer idea of what it is doing. It is very possible he will even shut it down if he is not satisfied with the answers he gets.

Varda quickly raises $90 million after completing its first orbital manufacturing mission

2:18 pm

As expect, Varda announced yesterday that it raised $90 million in investment capital following the publication of the results of its first orbital manufacturing mission, where its returnable capsule was used to produce test pharmaceuticals in space that cannot be made on Earth.

Varda announced April 5 it raised a Series B round led by venture firm Caffeinated Capital, with participation from Lux Capital, General Catalyst, Founders Fund and Khosla Ventures. The company has raised $145 million to date. The funding round comes on the heels of the successful conclusion of its first demonstration mission, W-1, on Feb. 21 when the company’s capsule landed at the Utah Test and Training Range. The capsule had been part of a spacecraft launched in June 2023 to test the ability to produce pharmaceuticals in microgravity.

The new funding will allow Varda to scale up production of spacecraft that take advantage of microgravity to produce pharmaceuticals that are not possible or cost-effective to make on the ground.

The company already has a second returnable capsule scheduled for launch this summer on a Rocket Lab Electron rocket.
