Divers for documentary discover large piece of Challenger

8:55 am

Divers for a television documentary have discovered a large piece from the shuttle Challenger that broke up 74 seconds after launch in 1986.

The piece is more than 15 feet by 15 feet (4.5 meters by 4.5 meters); it’s likely bigger because part of it is covered with sand. Because there are square thermal tiles on the piece, it’s believed to be from the shuttle’s belly, Ciannilli said.

The fragment remains on the ocean floor just off the Florida coast near Cape Canaveral as NASA determines the next step. It remains the property of the U.S. government. The families of all seven Challenger crew members have been notified.

The History Channel will air a show describing this discovery on November 22nd.

Today’s blacklisted American: Student mob shuts down Ann Coulter speech at Cornell

4:59 pm

The modern dark age: Despite Cornell University’s refusal to agree to their demands and cancel the lecture, a mob of students prevented her from speaking last night, forcing her in the end to cancel her lecture because she could not get a word out without being interrupted.

What appears to have happened, the Review added, is that protesters “seemed to be employing a chain tactic, beginning just as soon as the last heckler was removed, so as to continuously speak over Coulter.”

As The College Fix previously reported, Cornell University had denied a student petition to disinvite Coulter.

And at the beginning of Coulter’s talk Wednesday evening, the dean of students warned the audience that disruptors would be removed and referred to the Office of Student Conduct, the Review reported.

A cliff face of volcanic erosion on Mars

A cliff face of volcanic erosion on Mars
Click for full image.

Today’s cool image is a variation of yesterday’s, showing another area on the edge of Mars’ largest volcanic ash field, dubbed the Medusae Fossae Formation and about the size of India. This time however the edge is an abrupt cliff, not the slow petering out of wind-shaped mesas.

The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 27, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what I very roughly estimate to be a 1,500 to 2,500 foot high cliff that appears to delineate the edge. To the north we have a plateau of intersperse layers of flood lava and ash. To the south those layers have eroded away, leaving a rough lava plain with a handful of scattered wind-sculpted mesas.

The overview map below, by providing a wider view of his region, makes its nature clearer.

Rocket Lab sets date for 1st launch from Wallops

9:38 am

On the same day it won a contract to build a control center for Globalstar’s satellite constellation, Rocket Lab also set December 7, 2022 as the target date for its first Electron launch from Wallops Island in Virginia.

The company had originally hoped to launch from Wallops two years ago, but delays caused by NASA’s bureaucracy in approving the flight termination software made that impossible.

With two operating launchpads, one in New Zealand and one in the U.S., Rocket Lab should now be able to ramp up its launch pace, assuming it has the customers. So far this year the company has done about one launch per month.

Atlas-5 completes last launch at Vandenberg

8:58 am

ULA’s Atlas-5 rocket early this morning successfully launched a NOAA weather satellite, completing this soon-to-be-retired rocket’s last launch from Vandenberg Space Force Base.

The company also successfully tested an inflatable heat shield it wants to use to safely recover and reuse the first stage engines on its new Vulcan rocket.

The leaders in the 2022 launch race:

51 SpaceX
48 China
19 Russia
9 Rocket Lab
8 ULA

American private enterprise now leads China 74 to 48 in the national rankings, but trails the rest of the world combined 76 to 74.

  • Thales Alenia Space completes next Cygnus, ready for shipment to U.S.

    • I am not sure if Thales installs the solar panels. If so, I suspect they will want to wait before shipment in order get a report on why one panel did not deploy on the Cygnus now in orbit. It is also possible that Northrop Grumman installs the panels, and will handle any revisions after delivery.

 

  • A closer look at Virgin Orbit’s financial picture

    • Apparently, the delays in the UK are seriously hurting the company. Because they only have one 747 carrier plane, Cosmic Girl, they can only do one launch at a time, which means later launches — and the revenue they produce — are pushed back. The company thus desperately needs a second 747 so the delays on one launch don’t impact others.

China switches heavy-lift Long March 9 from expendable to reusable

3:34 pm

China has abandoned its original plans to build its Long March 9 heavy lift rocket — intended to be comparable to NASA’s SLS — as an expendable rocket with side boosters and instead design it with a reusable first stage.

A new model of a Long March 9 rocket featuring grid fins and no side boosters recently went on display at the ongoing Zhuhai Airshow in southern China, prompting speculation that the long-standing plan of an expendable rocket had been dropped.

Liu Bing, director of the general design department at the China Academy of Launch Vehicle Technology (CALT), later confirmed the new direction in an interview with China Central Television Nov. 7. The new, current plan for the rocket will be a three-stage, 108-meter-high, 10-meter-diameter and 4,180 metric ton rocket capable of delivering 150 tons to low Earth orbit (LEO), 50 tons to lunar transfer orbit (LTO), or 35 tons to Mars transfer orbit. The rocket is scheduled to be ready for test flight around 2030.

The design however has not been finalized.

It appears that China has been watching NASA’s attempts to launch SLS, and decided copying that rocket is likely a mistake. So instead, they have decided to copy Falcon 9 instead, though make Long March 9 a much bigger rocket.

All of this however is really nothing more than engineering by PowerPoint. Nothing so far really exists, and any plans for a rocket whose first test launch is eight years away are plans that no one should take very seriously.

Rocket Lab leases engine test facility at Stennis

3:27 pm

Rocket Lab has finalized a 10-year lease for using one of the engine test facilities at NASA’s Stennis Space Center in Mississippi for developing the Archimedes rocket engine for its new Neutron rocket.

With the new agreement, the A-3 Test Stand and about 24 surrounding acres at Stennis will be incorporated into the Archimedes Test Complex. Archimedes is Rocket Lab’s new liquid oxygen and liquid methane rocket engine that will power its large, reusable Neutron rocket.

Rocket Lab will have exclusive access to use and develop the A-3 Test Stand area, including associated propellant barge docks and buildings. The initial 10-year agreement includes an option to extend an additional 10 years.

The Mississippi Development Authority is providing assistance for Rocket Lab to develop the new site and to relocate and install needed equipment.

With this agreement Rocket Lab is clearly moving forward aggressively in its project to build a new rocket that can complete head-to-head with SpaceX’s Falcon 9.

Not one climate model predicts global temperature; all predict too much warming

Climate models versus actual observations for the past 50 years

Even as we wait for the final results in numerous elections yesterday, I thought I would throw the chart to the right out for my readers to digest.

The chart was created by climate scientist Roy Spencer of the University of Alabama, who has also been one of the principal investigators for one of NASA climate satellites.

As seen in the accompanying plot, 50-year (1973-2022) summer (June/July/August) temperature trends for the contiguous 48 U.S. states from 36 CMIP-6 climate model experiments average nearly twice the warming rate as observed by the NOAA climate division dataset.

…The official NOAA observations produce a 50-year summer temperature trend of +0.26 C/decade for the U.S., while the model trends range from +0.28 to +0.71 C/decade.

Not one climate model predicted the actual global temperature for the past half century. All predicted too much warming, with about half the models predicting twice as much warming as actually occurred.

In other words, the models continue to express opinion, not science. To rely on any model for establishing climate policy is not only foolish, it is downright irresponsible.

But don’t worry. Joe Biden and the Democrats are on their game, and will shut down all fossil fuel energy sources, because it simply feels right to them.

Meanwhile, on a related side note, the fact that it is no longer possible to finish counting the votes on election day — something that Americans did routinely for more than two centuries long before computers — either is another sign that serious election tampering is going on, or is a clear demonstration that we have entered the new dark age, where it will no longer be possible to accomplish some of the most basic tasks of a true civilization.

In either case, the barbarians rule, and we all suffer because of it.

Erosion at the edge of Mars’ biggest volcanic ash field

Erosion at the edge of Mars' biggest ash field
Click for full image.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 13, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It is another fine example of the wind-blown sculpted terrain that one finds routinely in Mars’ largest volcanic ash field, dubbed the Medusae Fossae Formation. About the size of India, this gigantic field is thought to be the source of most of the dust on Mars.

This particular location sits on the northernmost edge of that huge field. The elongated mesas mark the field’s edge, disappearing to the north but becoming thick and extensive to the south. The prevailing southeast-to-northwest winds have acted to clean most of the ash away.

We can get an idea about how deep and pervasive that field once was at this location by the pedestal crater in the middle right. Once, the floor of that crater was below the top of the ash field. At that time, the top of the dunes marked the general ground level across this entire image. Over time, the winds blew most of this material away, but the denser packed floor of the crater resisted that erosion, and thus now stands above the surrounding terrain.

The more normal-looking craters nearby could have occurred before the ash was deposited, or after it was blown away. The impact that created the pedestal crater however occurred when the ash covered everything here.
