After the third safe mode event in six months, all caused by issues with the same gyroscope, engineers have decided to shift the Hubble Space Telescope to what they call one-gyro mode, whereby the telescope is pointed using only one gyroscope, and the remaining working gyro is kept in reserve.

The spacecraft had six new gyros installed during the fifth and final space shuttle servicing mission in 2009. To date, three of those gyros remain operational, including the gyro currently experiencing problems, which the team will continue to monitor. Hubble uses three gyros to maximize efficiency but can continue to make science observations with only one gyro. NASA first developed this plan more than 20 years ago, as the best operational mode to prolong Hubble’s life and allow it to successfully provide consistent science with fewer than three working gyros. Hubble previously operated in two-gyro mode, which is negligibly different from one-gyro mode, from 2005-2009. One-gyro operations were demonstrated in 2008 for a short time with no impact to science observation quality.

While continuing to make science observations in one-gyro mode, there are some expected minor limitations. The observatory will need more time to slew and lock onto a science target and won’t have as much flexibility as to where it can observe at any given time. It also will not be able to track moving objects closer than Mars, though these are rare targets for Hubble.

This NASA press release is carefully spun to hide the simple fact that in one-gyro mode, the telescope will simply not be able to take sharp pictures. » Read more

FAA issues launch license for the fourth test orbital launch of Starship/Superheavy

3:10 pm

FAA today issued [pdf] the launch license for SpaceX’s fourth test orbital launch of Starship/Superheavy, effective June 4, 2024, thus allowing the company to proceed with its planned June 6, 2024 launch date.

The two-hour launch window opens at 7 am (Central). SpaceX’s live stream will begin 30 minutes earlier. From SpaceX’s Starship website:

The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy. The primary objectives will be executing a landing burn and soft splashdown in the Gulf of Mexico with the Super Heavy booster, and achieving a controlled entry of Starship.

To accomplish this, several software and hardware upgrades have been made to increase overall reliability and address lessons learned from Flight 3. The SpaceX team will also implement operational changes, including the jettison of the Super Heavy’s hot-stage following boostback to reduce booster mass for the final phase of flight.

Flight 4 will fly a similar trajectory as the previous flight test, with Starship targeted to splashdown in the Indian Ocean. This flight path does not require a deorbit burn for reentry, maximizing public safety while still providing the opportunity to meet our primary objective of a controlled Starship reentry.

This FAA approval is wonderful news, considering the red-tape delays the agency has previously caused to SpaceX’s efforts. It suggests that officials there are trying hard to speed up their paperwork. If so, the gap between this flight and fifth might be shorter than the three month gap seen between the third flight in March and this flight on June 6th.

Research continues to find the COVID jab caused more deaths than it prevented

11:18 am

The rise in excess deaths after the jab arrived
This graph, from CDC research, shows that
the number of excess deaths began skyrocketing
in mid-2022, after the jab was rolled out

Two stories this week both add weight to the growing pile of evidence in the past two years that the COVID jab not only did little to prevent the spread of that flu-like virus, it caused more deaths than it prevented.

First, research from Oxford University in Great Britain that studied more one million children aged 5 to 11 found that only those who got the jab would develop myocarditis and pericarditis.

The study did note that this study recorded no deaths from these heart conditions, but one must wonder what the parents of those young children think about that. You used to have a healthy kid who after getting the jab now has a serious heart condition that certainly has the potential of shortening that child’s life.

While the study found the jab seemed to reduce COVID in adolescents, it made no different for younger children. “Vaccinated children … were not substantially different from unvaccinated children in terms of COVID-19 infection and hospitalization.”

In other words, the jab overall did more harm then good among young children. And the harm was significant.

Next, research in the Netherlands of the continuing rise of excess deaths worldwhile strongly suggests once again that it is the jab itself that might be causing it.

ESA requests information from European rocket startups

9:16 am

The European Space Agency (ESA) has released a request for information from European rocket startups to outline their capabilities and plans so that ESA can assess whether they qualify for future launch contracts.

Currently, ESA is working towards publishing a competitive tender in early 2025 for the award of contracts to allow European launch providers to demonstrate their ability to provide the capacity to serve institutional mission needs. To better define this competitive tender and align the challenge in the best possible way to incentivize providers, ESA has published a Request for Information call. “This Campaign will let economic operators express their views and expectations on the future of European access to space and actively participate in the definition of the European Launcher Challenge,” explains the call.

The call is limited to companies in Europe. The information the companies provide will then be used by ESA to shape the actual contract offers in 2025. The long term goal is for independent and competing European rocket companies to replace the Ariane-6, and provide a fleet of rockets of all types capable of launching European payloads faster and for much less money.

French startup captures Russian satellite maneuvering close to another geosynchronous satellite

9:09 am

The French startup Aldoria has released a short movie taken by its ground telescopes showing a Russian “inspector” satellite maneuvering close to another geosynchronous satellite.

In a recent operation, Aldoria detected a sudden close approach by the Russian Luch Olymp K-2 (Luch-2) to a satellite positioned in geostationary orbit (GEO). This manoeuvre occurred on April 12, around 35,780 km in altitude, highlighting the increasing complexity of space activities. Luch Olymp 2, known for its unusual manoeuvres was predicted, by Aldoria, to closely approach the satellite prior to the observed manoeuvre. The original Luch-1, launched in 2014, was known for similar abnormal behaviour, creating a heightened sense of vigilance within the space community. Luch-2, like its predecessor, has a history of unusual manoeuvring near other satellites in geostationary orbit, which has also generated suspicions regarding its mission.

You can see the video here.

In the past year it appears the entire aerospace industry in Europe has come alive, no longer captured by the European Space Agency’s government-owned commercial arm, Arianespace. Instead, there are companies popping up everywhere, doing the kinds of entrepreneurial work American companies have been known to do since the founding of the country.

The competition for business and the amount of innovation in space should get very brisk in the next few years.

SpaceX now targeting June 6, 2024 for Starship/Superheavy launch

8:58 am

Over the weekend SpaceX announced on X that it has now delayed by one day its targeted date for the fourth orbital test flight of its Starship/Superheavy rocket, from June 5th to June 6th.

No reason was given for the delay, though the company notes on its webpage for the mission that it is still awaiting regulatory approval.

Musk underlined the company’s readiness to launch however with his own tweet on June 2, stating simply that “Starship is ready to fly.”

From the FAA however we still have silence.

Early today the ascender of China’s Chang’e-6 lunar probe lifted off the surface on the Moon’s far side, carrying the samples it had obtained both by drilling and the use of a robot arm.

The ascender took off at 7:38 a.m. (Beijing Time) from the moon’s far side. A 3,000-newton engine, after working for about six minutes, pushed the ascender to the preset lunar orbit, according to the CNSA.

The Chang’e-6 probe, comprising an orbiter, a lander, an ascender and a returner — like its predecessor Chang’e-5 — was launched on May 3. The lander-ascender combination, separated from the orbiter-returner combination on May 30, touched down at the designated landing area in the South Pole-Aitken (SPA) Basin on June 2.

The spacecraft finished its intelligent and rapid sampling work, and the samples were stowed in a container inside the ascender of the probe as planned, the CNSA said.

At some point, not yet specified, the ascender will dock with the orbiter-returner and transfer the samples to the returner, which after a period in orbit awaiting the right moment will then separate and head back to Earth.

China releases movie taken by Chang’e-6 during its lunar descent

8:45 am

Chang'e-6 landing zone
Chang’e-6’s landing zone is indicated by the
red box, on the edge of Apollo Creater
(indicated by the wavy circle).

China’s state-run press yesterday released a short movie created from images taken by its Chang’e-6 lander during its descent to the lunar surface on the far side of the Moon this past weekend.

I have embedded that footage below. The final five frames however are very puzzling, in that they do not appear to show a smooth descent to a specific spot, but appear to jump about wildly. Moreover, the footage does not appear to show the actual landing itself, but appears to stop while the spacecraft is still above the ground.

It is possible that this footage is simply showing the spacecraft’s software searching for a good landing spot, combined with a decision in China not to release footage of the actual touchdown. It could also be that something has gone wrong, and they are stalling about saying so. This last possibility I think very unlikely, but it must be considered, based on the information available.

Boeing Starliner launch scrubbed at T-3:50

10:10 am

UPDATE: The launch is now scheduled for June 5, 2024 at 10:52 am (Eastern).

For reasons that appeared related to the ground system’s of ULA’s Atlas-5 rocket, the first manned launch of Boeing’s Starliner’s capsule was scrubbed today at T-3:50.

It appears they want to try again tomorrow at 12:03 pm (Eastern), assuming ULA can figure out what happened.

The repeated scrubs and delays that have so far prevented this launch are beginning to remind my of my childhood watching the early NASA launch attempts during the Mercury program. Then, they hadn’t done this before, and were being very careful about everything.

Now, it seems that NASA, ULA, and Boeing are acting the same way, and that is probably because they are very nervous about Starliner and don’t want anything to go wrong.

I had intended to embed the live stream, but slept late (it IS the weekend, y’know). Sorry.

Beware the cornered rat!

Trump is only in the way

The absurd guilty verdict against Donald Trump yesterday by a jury of twelve partisan New York Democrats confirms something that we should have recognized back in 2016. The Democratic Party and its partisan supporters will brook no opposition, and are willing to do anything — including throwing the Constitution, the Bill of Rights, and the entire legal system in the trash can — in order to maintain their control of the government.

In 2016 they were outraged that an outsider like Donald Trump could become president, and for the next four years exhibited that irrational outrage by pushing one fake and slanderous scandal against him after another, from idiotic claims that he deprived visitors of the same portions of ice cream as he got to the utterly false accusations that he won the election due to Russian help.

To defeat him in 2020 it appears the administrative state teamed up with many Democratic Party governors to create the panic over COVID as well as the outrage over the drug overdose death of an addict during his arrest in Minnesota. The former allowed those governors and state governments to corrupt the election system.

The latter outrage over George Floyd allowed the armed wing of the Democratic Party, its BLM and Antifa thugs, to loot and riot throughout the country, thus reinforcing the absurd lockdown rules imposed because of COVID.

It remains unclear whether the the election shenanigans that followed gave Biden the victory, but any objective review of the facts and the many vote tampering allegiations put forth by numerous election officials nationwide suggests it was very possible.

Thus, Biden became president, and since then the Democrats have been on an aggressive blacklisting campaign to destroy anyone who opposed them. That campaign reached its summit yesterday with Trump’s conviction in what could be called the most ludicrous and disgusting legal case ever brought against any American. Not only can no one name the crime that Trump was supposed to have committed, the jury was given instructions that it could find him guilty even if they themselves couldn’t agree on that crime.

As expected, the public’s response to Trump’s conviction has been to increase his support. » Read more

SpaceX completes second Starship/Superheavy dress rehearsal countdown; no launch licence yet from FAA

9:22 am

Though SpaceX has now successfully completed a second Starship/Superheavy dress rehearsal countdown in preparation for its targeted June 5, 2024 launch date, the FAA has still not issued the company a launch licence.

The report at the link is very optimistic about the FAA issuing the license, though there as yet no indication that it will do so.

There are two ways to return to flight. Previously, all Starship mishaps were closed using Path One, which means the FAA accepts a SpaceX-led mishap investigation report, where the operator identifies corrective actions for the vehicle and implements them on future flights.

For this flight, SpaceX chose Path Two, which involves an FAA public safety determination. In this process, the FAA makes a safety determination based on all available information to see if the previous flight involved safety-critical system failures. If successful, a return to flight can be conducted even without the closure of the mishap report.

In a statement to [NASASpaceFlight], the FAA reported: “After a comprehensive review, the FAA determined no public safety issues were involved in the anomaly that occurred during the SpaceX Starship OFT-3 launch on March 14. This public safety determination means the Starship vehicle may return to flight operations while the overall investigation remains open, provided all other license requirements are met.

SpaceX has not yet received FAA license authorization for the next Starship launch.”

We shall see. I suspect the people at the FAA want to issue that license. I also suspect that the White House is demanding the full investigation be completed beforehand.

Engineers lose contact with Japan’s Akatsuki Venus orbiter

9:11 am

According to a terse announcement by Japan’s space agency JAXA on May 29, 2024, engineers from its Institute of Space and Astronautical Science (ISAS) have lost contact with Japan’s Akatsuki Venus orbiter.

ISAS has lost contact with Akatsuki after an operation in late April due to an extended period of low attitude stability control mode, and is currently making efforts to reestablish communication with the spacecraft.

Akatsuki has had a spotty and complex life. It was launched in 2010, but failed to enter Venus orbit as planned in two attempts in 2010 and 2011 because of a failure in its main engine. Engineers then improvised and — after orbiting the Sun for several years — were able to get it into Venus orbit in 2015 using only its attitude thrusters. Its primary mission ended in 2018, but it continued to study Venus’ atmosphere since.

Assuming Akatsuki is not recovered, as of now there are no operating orbiters at Venus. A mission by the private company Rocket Lab is expected to launch before the end of this year, followed by an orbiter from India in 2026. A NASA mission meanwhile is in limbo and will likely never fly, due to budget decisions at the agency, which took its funding and gave it to the troubled Mars Sample Return mission.
