Rocket Lab launches seven satellites; recovers first stage from ocean

6:46 pm

Rocket Lab today successfully used its Electron rocket to place seven smallsats into orbit, lifting off from New Zealand.

The first stage used parachutes to softly splash down in the ocean, where it was recovered for refurbishment and relaunch. As this stage is the first in which this full reuse will be attempted, the ability to refurbish the stage after its salt water swim remains the critical factor. We will not know its state until a complete inspection plus static fire engine tests are completed.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
6 Rocket Lab
5 India

American private enterprise now leads China in successful launches 54 to 26, and the entire world combined 54 to 45, while SpaceX alone still leads the rest of the world (excluding other American companies) 47 to 45.

Flat-topped Martian mesa

3:58 pm

Flat-topped mesa on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on April 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows only one of many flat-topped mesas in a chaos terrain region dubbed Oxia Chaos.

The mesa top is about 540 feet above the floor of the canyon to the north, which in turn is about 840 feet below the flat terrain north of it. That flat terrain to the north is not part of the chaos terrain, however, but the northern rim of the plateau that surrounds the chaos. Moreover, this particular piece of rim is separating from the plateau, as shown near the top of this January 16, 2008 context camera image from MRO. At some point in the future it will break off and fall into that canyon and on top of this mesa.

Chandrayaan-3 completes second orbital maneuver

9:32 am

Chandrayaan-3's mission profile

According to India’s space agency ISRO, its lunar lander/rover Chandrayaan-3 today completed second orbital maneuver, raising the spacecraft’s orbit around the Earth from 41,762 by 173 kilometers to 41,603 x 226 kilometers.

The graphic to the right shows the entire mission profile of Chandayaan-3. It still has three more orbital adjustments to make in Earth orbit before it does its trans-lunar-injection burn to send it to the Moon. Once it arrives in lunar orbit it will then have to make six orbital adjustments to lower its orbit before making the descent to the surface.

The lunar landing itself is presently scheduled for August 23, 2023.

An apparent rocket section washes up on Australian coast

9:19 am

What appears to be a section of India’s PSLV rocket washed up on the western Australian coast yesterday, though at the moment the identity of the wreckage as not been confirmed.

Dr Alice Gorman, an expert in the field of space archaeology, said she believes the object is a fuel cylinder that came from the the third stage of India’s polar satellite launch vehicle rocket (PSLV), as many have suggested on social media.

The article includes a picture of that stage in orbit during a 2017 launch, and the similarity is obvious. If true, its specific launch at present remains unknown, though it appears it could have been floating in the ocean for years, a fact that is surprising in itself.

SpaceX launches using its second Falcon 9 first stage on its sixteenth flight

9:14 pm

SpaceX tonight successfully launched 54 Starlink satellites into orbit, lifting off from Cape Canaveral.

The Falcon 9 rocket used a first stage flying on its sixteenth flight, landing successfully on a drone ship in the Atlantic. That is the second 1st stage in SpaceX’s fleet to complete that many flights. Both first stages completed their sixteen flights in only three years, which means that those two first stages have actually flown more times than the entire United States rocket industry did annually from 2000 to 2019. I don’t have a full count, but I suspect both stages have launched in those three years more satellites then the totals for almost all other nations, excepting possibly Russia and the U.S. Both probably allowed SpaceX to amortize the cost of those launches considerably, possibly as much as 90%.

Just remember: Rocket industry experts were insisting even as late as 2016 that it was impractical to make rocket stages reusable, that to make a profit “a partially reusable rocket would need to launch 35-40 times per year to maintain a sizable production facility while introducing reused hardware into the manifest.” Based on that calculation, these experts determined with utmost certainty that a partly reusable rocket — like the Falcon 9 — could never make a profit.

Elon Musk must have agreed, and decided he needed an extra profit center for the Falcon 9. Starlink has provided that profit center. It not only needs that many launches, and pays for them, its profit stream from its internet customers is already adding to SpaceX’s bottom line.

Regardless, Musk has proved these “experts” utterly wrong. I always thought they were talking through their hat, but had no way to prove it. Thank you Mr. Musk for proving the point.

Note too that the two fairing halves on this flight were also reused, completing their ninth and tenth flights respectively.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
5 Rocket Lab
5 India

American private enterprise now leads China in successful launches 53 to 26, and the entire world combined 53 to 45, while SpaceX alone now leads the rest of the world (excluding other American companies) 47 to 45.

And it is doing this with that impractical, unprofitable, and impossible reusable Falcon 9 rocket. Heh.

Another look at the vastness of Valles Marineris on Mars

1:06 pm

The vast Valles Marineris
Click for interactive map.

This week I have returned several times to the giant Valles Marineris canyon on Mars in an attempt to capture its incomprehensible and glorious scale. Without question this canyon is going to become one of the prime tourist spots when humans begin living and working throughout the solar system. Fortunately, its vast size will mean that it will take many many centuries before it even becomes close to crowded there.

Today I try a different approach, using the global mosaic created by scientists at Caltech from the context camera images taken by Mar Reconnaissance Orbiter (MRO). That mosaic processes the images to allow one to see the surface from an oblique angle. The picture to the right covers one small part of the eastern end of Valles Marineris (the white rectangle in the inset), but though small the scale once again is gigantic.

The three white dots are our reference points, one on the north rim, one on the south, and one in the middle on the peak of that central mountain chain. Beginning from the south, the distance from the rim to the middle mountain peak is 43 miles, with the elevation dropping almost 13,000 feet to the floor of the south canyon, than rising almost 10,000 feet to the middle peak. The northern canyon is smaller. From the peak to the north rim is 27 miles, dropping about 9,300 feet and then rising about 8,500 feet to the north rim.

From rim to rim the distance is about 70 miles. Since the middle mountain chain about 18 miles wide, it fills only about 25% of the entire canyon.

In every case, the Grand Canyon would be merely be a small side canyon here. The depths are twice as deep, and the distances are many times larger. In width alone at this point Valles Marineris is seven times wider than the widest part of the Grand Canyon, and this is by far not Valles Marineris’s widest point.

NASA survives first budget review in Congress

9:51 am

The first 2024 budgets approved by Senate and House appropriation committees for NASA maintain about the same current numbers from NASA’s 2023 budget.

The House committee is recommending $25.367 billion, just shy of the $25.384 billion NASA has now. The Senate committee is proposing $25.000 billion, a greater reduction from current spending. Biden requested a 7.1 percent increase for FY2024, $27.2 billion.

In the House the Republican leadership is requiring this House committee to impose a 28.8% cut in the total money allocated to all the agencies under its control (Justice, Commerce, and Science). It appears the committee members have decided to find the cuts in the other departments, such as the Justice Department. In fact, this first budget review strongly suggests Justice is about to see huge cuts, something that corrupt and partisan agency richly deserves.

As for NASA, the Senate report [pdf] had harsh words for the growing expense of the Mars Sample Return mission, and proposed major cuts, including the possibility of eliminating the project entirely. Instead, the Senate committee preferred wasting that money on Artemis and SLS.

UK government reluctantly admits its space regulatory framework is a problem

9:36 am

According to a report issued by a committee formed by a number of members of the United Kingdom’s parliament, the regulatory licensing framework for its space launch industry is a problem that needs fixing, and in a hurry.

The report also expressed concern about the licensing delays that led to the Virgin Orbit launch being postponed. Virgin Orbit and some of its satellite customers were critical of the UK regulatory process, which was led by the Civil Aviation Authority.

But the committee concluded there was no evidence that the regulatory system contributed to the failure of the Virgin Orbit. The report did state, however, that there is “insufficient co-ordination between the large number of regulatory bodies involved in licensing launches, and this continues to place unnecessary burdens of complexity and administration on companies”.

The MPs [members of parliament] are calling on the Government to take steps to improve the licensing system of UK satellite launch.

It is amusing how these politicians speak from both sides of their mouths. First they say the regulatory system did not contribute to Virgin Orbit’s failure, but then admit the regulatory system is so complex and messy that anyone can see that it certainly did contribute to that failure. It took that system fifteen months to approve the launch, even though Virgin Orbit expected that approval to come in half that time.

Whether this MP report will force action remains unclear. As I noted earlier this week, Orbex applied for a launch license seventeen months ago for a launch it hopes to complete at the Sutherland Spaceport before the end of this year, and it is as yet unclear if any license has been issued. The UK’s two spaceports cannot compete if it is going to take one to two years for each launch license to be approved

Rocket Lab gets two-launch deal with Japanese satellite company

9:27 am

Rocket Lab today announced that it has signed a two-launch deal with the Japanese satellite company Synspective, bringing to six total the number of Synspective satellites its Electron rocket will place in orbit.

Rocket Lab has been launching for Synspective since 2020 when the Company deployed the first satellite in Synspective’s synthetic aperture radar (SAR) constellation, which is designed to deliver imagery that can detect millimetre-level changes to the Earth’s surface from space. Since that first mission, Rocket Lab has been the sole launch provider for Synspective’s StriX constellation to date, successfully deploying three StriX satellites across three dedicated Electron launches. Including the two new missions, Rocket Lab is now scheduled to launch three missions for Synspective beginning in late 2023 from Launch Complex 1 in New Zealand.

This deal illustrates Rocket Lab’s continuing strong position in the launch market, while simultaneously illustrating the lack of any Japanese presence. Japanese Synspective might prefer to work with a Japanese rocket, but none exists that can compete with Rocket Lab.

ULA officially admits first Vulcan launch is delayed to end of year

9:19 am

Though the announcement was not news or unexpected, ULA’s CEO Tory Bruno yesterday officially confirmed that the first Vulcan launch will not occur before the fourth quarter of this year, not this summer as hoped.

In a call with reporters July 13, Tory Bruno, president and chief executive of ULA, said the changes to the Centaur upper stage stemmed from an investigation into a test mishap in March, where hydrogen leaked from a Centaur test article and ignited, damaging both the stage and the test rig. The company announced June 24 that it would delay the launch to make “minor reinforcements” to the Centaur.

Bruno also poo-pooed the significance of a failure of a Blue Origin BE-4 engine during a static fire test in mid-June, a failure that had been kept secret until this week.

“This doesn’t indict the qualification at all,” he said, noting that BE-4 engines have more than 26,000 seconds of cumulative runtime. “We’re very confident in the design and the workmanship of the assets that have passed acceptance. This is not unexpected.”

Forgive me if I don’t take him entirely at his word. I guarantee his engineers are looking at that failure very closely to make absolutely sure it doesn’t indicate issues with the two engines on that first Vulcan rocket. It is very likely this is part of the reason that first launch is now delayed until the end of the year.

Solid-fueled second-stage motor for Japan’s new Epsilon-S rocket explodes during static fire test

9:10 am

A solid-fueled second stage of Japan’s upgraded Epsilon-S four-stage rocket exploded 57 seconds into a two minute static fire test today, likely preventing that rocket’s planned first launch this year.

Police received an emergency call shortly after 9 a.m. from a nearby resident reporting that she heard “a loud noise and saw smoke” rising from the Noshiro Rocket Testing Center.

JAXA said that an explosion occurred during a combustion test of the second-stage engine of the Epsilon S rocket, which is an improved model of the small solid-fuel Epsilon rocket, at the facility in the prefecture in the northeastern Tohoku region.

While explosions during static fire tests of liquid-fueled rockets occur periodically, for a solid-fueled motor to explode seems much rarer, and suggests the mix and placement of the solid-fuel within the stage did not occur properly.

This failure continues a string of failures within Japan’s government-run space program, including a failure during the first launch of its new large H3 liquid-fueled rocket earlier this year. At present Japan’s space agency JAXA has set August 26th for one of the last launches of the rocket the H3 is replacing, the H2A, carrying an X-ray space telescope and a small lunar lander. Though today’s failure involves very different technologies and should therefore not impact that launch, it is possible JAXA will stand down entirely to see if there was some systematic issue throughout its management. It sure appears there is.

India successfully launches Chandrayaan-3

8:35 am


Click for interactive map.

India today successfully launched its Chandrayaan-3 lunar lander/rover probe toward the Moon, carried aloft by its LV-M3 rocket (a variation of its GSLV) from its coastal spaceport in Sriharikota.

Chandrayaan-3 carries the Vikram lander, which will bring the Pragyan rover to the surface. Pragyan will spend about two weeks operating on the lunar surface. The location is indicated by the red dot on the map to the right, in the high southern latitudes. The white cross marks the lunar south pole. Russia’s Luna-25 is scheduled to launch sometime in mid-August.

It will take time to get Chandrayaan-3 into the right lunar orbit for landing, which is presently scheduled for August 13, 2023.

For India this was its fifth successful launch for the year, the most since 2019, before it panicked over COVID. The leaders in the 2023 launch race:

46 SpaceX
26 China
9 Russia
5 Rocket Lab
5 India

American private enterprise still leads China in successful launches 52 to 26, and the entire world combined 52 to 45, while SpaceX by itself still leads the rest of the world (excluding other American companies) 46 to 45.
