India’s SSLV new smallsat rocket fails during static fire test

9:20 am

According to sources inside India’s space agency ISRO, a static fire test of the first stage of its new Small Satellite Launch Vehicle (SSLV) rocket was a failure, and that the planned April inaugural launch will likely be delayed.

“Oscillation was noticed after 60 seconds into the test and nozzle was blown out near the bucket flange where it’s attached with the motor at around 95 seconds”, sources in the Bengaluru-headquartered space agency said. It was supposed to be tested for a total duration of about 110 seconds, officials said.

The Indian Space Research Organisation had targeted to launch the first development flight of SSLV (D1) in April and may now in all probability have to revise this schedule.

Fixing the problem and repeating the test will likely delay the first launch by six months at least.

SSLV is being designed by ISRO to compete against companies like Rocket Lab in the emerging smallsat market and is thus much cheaper and faster to assemble and launch.

Ingenuity to fly on Mars no earlier than April 8th

9:03 am

NASA and the Perseverance engineering team announced yesterday their specific plans for the first flights oft he Ingenuity helicopter, setting the flight date as no earlier than April 8th.

They are presently driving Perseverance to its “airfield,” a 33×33 foot area. The deployment then will take six days, because there are a number of steps involved to position and place the helicopter on the ground properly.

Once the team is ready to attempt the first flight, Perseverance will receive and relay to Ingenuity the final flight instructions from JPL mission controllers. Several factors will determine the precise time for the flight, including modeling of local wind patterns plus measurements taken by the Mars Environmental Dynamics Analyzer (MEDA) aboard Perseverance. Ingenuity will run its rotors to 2,537 rpm and, if all final self-checks look good, lift off. After climbing at a rate of about 3 feet per second (1 meter per second), the helicopter will hover at 10 feet (3 meters) above the surface for up to 30 seconds. Then, the Mars Helicopter will descend and touch back down on the Martian surface.

Several hours after the first flight has occurred, Perseverance will downlink Ingenuity’s first set of engineering data and, possibly, images and video from the rover’s Navigation Cameras and Mastcam-Z. From the data downlinked that first evening after the flight, the Mars Helicopter team expect to be able to determine if their first attempt to fly at Mars was a success.

The data from this first attempt will determine what they do next.

UPDATE: Below the fold is an illustration of that planned first flight, showing that they hope to send the rover toward the north, take some images, and then fly it back to its airfield, with a second landing site option at the far end of its flight.

SpaceX successfully launches another 60 Starlink satellites

8:51 am

SpaceX early today successfully used its Falcon 9 rocket to place another 60 Starlink satellites into orbit, bringing that constellation to over 1,300 satellites.

The first stage landed successfully, for the sixth time. Both fairing halves were also reused, and their recovery method has now been simplified:

SpaceX has recently appeared to adjust its fairing recovery strategy. The ships previously dedicated to fairing catch attempts, GO Ms. Chief and GO Ms. Tree, have been stripped of their nets and arms, a possible sign that dry fairing recoveries will no longer be attempted. Post-splashdown recovery has proven to be fairly successful, as recent missions frequently use fairing halves that have flown once if not multiple times before.

The leaders in the 2021 launch race:

9 SpaceX
6 China
4 Russia
2 Rocket Lab

Counting all launches, the U.S. now leads China 13 to 6 in the national rankings.

Today’s blacklisted Americans: Anyone who worked for Trump

12:09 pm

The cancelled Bill of Rights
A document no one in Washington believes in.

Blacklists are back and the Democrats got ’em: It is now very clear that anyone who worked for President Trump during his term in office is now being blackballed by the political class in DC and in the media.

[R]esumes are gathering dust, book manuscripts are being rejected, and corporations are being threatened with boycotts if they hire members of Trump’s team. “They are being blocked everywhere,” said Matt Schlapp, chairman of the American Conservative Union.

It’s “natural for the party that lost the White House, just as we saw after the Bush and Obama administrations, to spend a few months in the wilderness, so to speak,” added Brian Walsh, a partner at PLUS Communications.

But this time feels different, and many critics have said it is deserved. “They took a wrecking ball to the ‘swamp.’ Why would the ‘swamp’ want them back?” a top K Street lobbyist asked. [emphasis mine]

I find the highlighted quote especially ironic, in that I think Trump’s biggest failure is that he did not take a wrecking ball to the “swamp,” never truly cleaned house, even when it was patently obvious — especially in agencies like the FBI and the Justice Department — that a housecleaning was desperately needed.

Twisted and tilted bedrock in Martian crater

11:36 am

tilted strata in Martin Crater
Click for full image.

Cool image time! The photo to the right, rotated cropped, and reduced to post here, is only a small example of the strangely tilted and twisted strata in the central peak region of 38-mile-wide Martin Crater on Mars. The full image shows more.

The picture was taken on January 12, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The section I’ve cropped out shows a series of stratified strata that are are not only significantly tipped from the horizontal, but have also been bent and deformed.

The crater itself is located about 260 miles south of Valles Marineris, as shown on the overview map below.

Perseverance dumps debris shield in preparation for Ingenuity deployment

8:59 am

Dumped debris shield under Perseverance
Click for full image.

On March 21st the Perseverance engineering team released the debris shield that had been attached to the bottom of the rover to protect the Ingenuity helicopter during its journey to Mars, and thus began the deployment process for releasing the helicopter itself.

The photo to the right, cropped and reduced to post here, shows that debris shield on the ground. The rover will next drive away from this spot and find the flat area where the helicopter will be placed on the ground for its April flight.

Yutu-2 & Chang’e-4 complete 28th lunar day on Moon

8:42 am

The new colonial movement: China’s lunar rover Yutu-2 and its lander Chang’e-4 have successfully completed their 28th lunar day on the far side of the Moon, and have been placed in hibernation for the long lunar night.

According to this article from China’s state-run press, Yutu-2 has now traveled 683 meters (2,241 feet) since its landing. In the past two lunar days the rover has traveled about 180 feet, continuing its journey to the northwest away from Chang’e-5. Their pace continues to be about 80 to 100 feet per lunar day.

On the radio

3:47 pm

For those who wish to listen to me and even call in to ask a question or comment or disagree with something I have said, I will be on The Space Show with David Livingston. tomorrow night for probably two hours, beginning at 7 pm (Pacific).

As always, your calls will be welcome. I don’t bite, though as John Batchelor says, I can get grumpy.

In addition, I will be on WCCO-AM in Minnesota to talk space stuff on the next night, March 31st, for forty minutes, beginning at 10:00 pm (Central).

A visit to Cydonia on Mars

Strange geology in Cydonia on Mars
Click for full image.

Cool image time! The Cydonia region on Mars, located at around 30-40 degrees north latitude in the northern lowland plains just beyond the transition zone up to the southern cratered highlands, is well known to many on Earth because it was here that the Viking-1 orbiter took a picture of a mesa that, because of the sun angle, made its shadows resemble a face. Thus was born the “Face on Mars” that consumed the shallow-minded among us — and thus the culture, media, and Hollywood — absurdly for decades, until Mars Global Surveyor took the first high resolution image and proved without doubt what was really obvious from the beginning, that it was nothing more than a mesa.

Cydonia however remains a very intriguing region of Mars, mostly because it is home to a lot of strange geology, as shown by the photo to the right, rotated, cropped, and reduced to post here. Taken on January 16, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows some of that strange and inexplicable geology.

While Cydonia is inside that 30-60 degree latitude band where MRO has imaged numerous glacial-type features, I do not know if many such features have been found there. Except for the pits and depressions in the photo’s lower right — which suggest decay in an ice sheet — little else at first glance in the picture clearly invokes any of the obvious glacial features one comes to expect. There appear to be what might be lobate flows in the image’s center going from the west to the east, but if they are glacial, they are so decayed to as leave much doubt.

The overview image below shows where Cydonia is on Mars, and helps explain partly what is found here.

Today’s blacklisted Americans: The oppressed fight back at Boise State

11:47 am

The good black half of this student
A typical slide from a critical race theory class.

They’re coming for you next: Forced to attend a bigoted critical race education class at Boise State University where a white student was apparently treated like scum, it appears other students there taped the session and forwarded it to the Idaho state legislature.

The results were somewhat gratifying.

[A]dministrators have abruptly suspended all of the school’s general education classes called “University Foundations 200: Foundations of Ethics and Diversity.”

“We have been made aware of a series of concerns, culminating in allegations that a student or students have been humiliated and degraded in class on our campus for their beliefs and values,” states a March 16 memo from President Marlene Tromp to the campus community. “This is never acceptable; it is not what Boise State stands for; and we will not tolerate this behavior,” Tromp stated. “…Given the weight of cumulative concerns, we have determined that, effective immediately, we must suspend UF 200.” She goes on to note that academic leadership will determine next steps “to ensure that everyone is still able to complete the course.”

Tromp’s decision came around the same time as Idaho lawmakers passed a state education budget that takes away about $409,000 from Boise State University because of its social justice curriculum, Idaho Ed News reports. [emphasis mine]

The highlighted words provide us the real reason Boise administrators suspended these race lectures. » Read more
