Upper stage of Chinese rocket fails during launch

8:45 am

According to China’s state-run press, the Chinese pseudo-company Landspace experienced a failure yesterday during the launch of its Zhuque-2E rocket from the Jiuquan spaceport in northwest China.

A later update by the pseudo-company said the failure involved the rocket’s second stage, though little other information was provided.

In 2023 the Zhuque-2 rocket was the first to reach orbit using methane fuel, during the rocket’s second launch attempt. Overall it has launched six times, with two failures, on its first launch and yesterday.

Landspace hopes to launch its Zhuque-3 upgrade next year, designed to eventually land the first stage and reuse it. This failure could very well delay that plan.

Jared Isaacman proves in an op-ed today why Trump dumped him

4:03 pm

Jared Isaacman
Jared Isaacman has now proven he was
the wrong man for NASA administrator

In an op-ed posted today by Jared Isaacman and Newt Gingrich, the two men pushed the idea that NASA should lead a new “mini-Manhattan Project” to develop “nuclear-electric-powered spaceships” in order to conquer the heavens.

The President’s budget calls for an eventual pivot away from NASA’s Space Launch System (SLS)—leaving the heavy-lift rocket business to a capable commercial industry. That pivot should be toward something no other agency, organization, or company is capable of accomplishing: building a fleet of nuclear-electric-powered spaceships and extending America’s reach in the ultimate high ground of space.

The NASA centers, workforce, and contractors that manage, assemble, and test SLS are suited to take on this inspiring and necessary challenge. NASA Center at Michoud, for example, built landing craft during WWII, the Saturn V during the space race, the Space Shuttle, and the SLS. It is now waiting for the next logical evolution to ensure the competitiveness of our national space capabilities.

Oy. What piffle. » Read more

Slope streaks within Mars’ largest mountain region

1:51 pm

Overview map

Today’s cool image revisits Lycus Sulci, the largest mountain range on Mars, about 1,400 mile wide and 1,800 miles long. The overview map to the right gives a sense of the roughness and chaotic nature of this region, extending north from Mars’ largest volcano, Olympus Mons.

At present scientists are unsure of the geology that formed Lycus Sulci, and how it is linked with Olympus Mons. The wide view to the right suggests it is the remains of a very ancient lava flow descending from the volcano that over time has become eroded to produce this wildly knobby terrain. That hypothesis remains unproven however. There is also evidence that the material here might instead be volcanic ash, deposited in many layers and eroded away with time.

The location of the cool image below is marked by the white dot, with the inset providing us a wider view of the surrounding terrain. Note the two craters to the north and west. Both appear to have been partly filled by flows coming from the south and east, respectively, adding weight to the theory that this region formed from lava flow.

SpaceX donates $4.4 million to upgrade beach access at Boca Chica

10:31 am

Even as leftist politicians and anti-Musk haters rage incoherently against SpaceX’s growing facility at Boca Chica, the company this week donated $4.4 million to upgrade the beach access and facilities at South Padre Island, near Starbase at Boca Chica.

Beachgoers visiting South Padre Island will soon be able to enjoy a surfside park with a smorgasbord of family-friendly amenities paid for by a $4.4 million contribution from Elon Musk’s SpaceX. Previously, MySA reported that the project was expected to cost $4.5 million, according to Texas Department of Licensing and Regulation records.

Cameron County Beach Access #3, a currently undeveloped pedestrian beach access located just outside the South Padre Island city limits, will soon begin construction on the latest phase of a multimillion-dollar improvement project that will transform it into a destination beach access. To that end, Cameron County leaders celebrated with a groundbreaking ceremony on Monday, August 11, at the access, located at 28495 State Park Road 100-North, on South Padre Island.

In other words, SpaceX is paying almost the entire bill for this work. It might now have the power to close these beaches when necessary, but it is also acting like a good citizen, improving those beaches for everyone when they are open.

It is expected this work will be completed by next year.

Webb: An Earth-sized exoplanet in habitable zone appears to lack an atmosphere

10:17 am

Scientists using the Webb Space Telescope have concluded that an Earth-sized exoplanet, orbiting the red dwarf star Trappist-1 in the habitable zone, does not appear to have an atmosphere, or if it does have one it is not like Earth’s.

The TRAPPIST-1 system is located 40 light-years away and was revealed as the record-holder for most Earth-sized rocky planets around a single star in 2017, thanks to data from NASA’s retired Spitzer Space Telescope and other observatories. Due to that star being a dim, relatively cold red dwarf, the “habitable zone” or “Goldilocks zone” – where the planet’s temperature may be just right, such that liquid surface water is possible – lies much closer to the star than in our solar system. TRAPPIST-1 d, the third planet from the red dwarf star, lies on the cusp of that temperate zone, yet its distance to its star is only 2 percent of Earth’s distance from the Sun. TRAPPIST-1 d completes an entire orbit around its star, its year, in only four Earth days.

Webb’s NIRSpec (Near-Infrared Spectrograph) instrument did not detect molecules from TRAPPIST-1 d that are common in Earth’s atmosphere, like water, methane, or carbon dioxide.

You can read the paper here [pdf].

The likelihood of life on this exoplanet has always been slim, simply because it orbits so close to the red dwarf, where it is vulnerable to the high energy flares the star periodically releases.

Update on next Starship/Superheavy launch

10:06 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after the October 2024 flight,
safely captured during the very first attempt

Link here.

SpaceX now appears to have completed the prelaunch testing of Starship prototype #37, having tested the ship again after swapping out an engine after the first static fire test. It is now moving to put Superheavy on the launchpad for its own static fire tests.

The bottom line is that SpaceX appears moving successfully towards a launch of the next test flight of Superheavy/Starship, its tenth, for sometime between August 22nd and August 28th.

The report also describes the company’s work to preserve Superheavy prototype #12, the first to be captured and recovered during the fifth orbital test flight in October 2024.

The picture to the right shows that Superheavy booster, hanging from the chopsticks just after it was captured.

Trump orders the federal agencies regulating space to review and streamline regulations

9:47 am

Trump defiant after being shot
Trump’s war with the swamp continues

Fight! Fight! Fight! In a new executive order issued yesterday, President Trump tasked NASA and the Transportation, Commerce, and Defense departments to work together to review and streamline the present regulations that have been hindering the American space industry for the past four years.

A summary of the order can be found here.

The order specifically tasks Transportation secretary Sean Duffy to review and streamline the regulations related to launches and re-entry, as well as the environmental requirements that were imposed during the Biden administration requiring numerous environment impact statements for practically any new project and even when an established project gets revised slightly. It has been these new rules that squashed the efforts of almost all the new American rocket companies during the Biden administration.

The order also demands that Commerce, Transportation, Defense, and NASA review the laws relating to coastal management that have allowed the states to block “spaceport infrastructure development.” All these agencies are also required to review their licensing rules to eliminate duplication while also eliminating rules that impede “novel space activities (missions not clearly or straightforwardly governed by existing regulatory frameworks).”

Finally, the order establishes a new position at the FAA but reporting directly to the Transportation secretary who will be expressly focused in following through on these regulatory reforms, with the primary goal to aid the commercial space industry.

While this order changes no specific regulations, it now forces the bureaucracy toward change, with deadlines set for action ranging from two to six months. Expect whole swathes of regulations and licensing requirements to disappear in the coming months. We might even see new rocket companies finally resume launches, something that ceased during the Biden years.

SpaceX completes two launches, reaching 100 successful orbital launches in 2025

9:15 am

Having successfully completed two Starlink launches last night, putting a total of 52 satellites into orbit, SpaceX has now accomplished 100 successful orbital launches in 2025.

First, in the early evening last night the company launched 24 satellites from Vandenberg in California, its Falcon 9 rocket first stage completing its fifth flight, landing on a drone ship in the Pacific.

Seven hours later it placed another 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage on this flight completed its tenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

100 SpaceX
44 China
11 Rocket Lab
9 Russia

SpaceX now leads the rest of the world in successful launches, 100 to 77.

SpaceX’s launch rate has become so routine that it is important to note the truly amazing nature of its achievement. Until 2018, the entire world had trouble completing 100 launches in a year. In fact, prior to SpaceX’s arrival it only happened because the Soviet Union in the ’70s and ’80s launched many short term small reconnaissance satellites that only stayed in orbit for a few months. When the Soviet Union fell the launch rate fell below 100 and did not recover until SpaceX began increasing its launch rate.

In other words, this one American private company has fueled a renaissance in space exploration. And it has done so by being efficient, innovative, and most important of all, profitable. And it all happened under the banner of freedom.
