A Martian knife mesa with terraces

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 21, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as a “layered mound.” It also shows a plethora of geological mysteries, all of which relate to the as yet not quite understood geological history of Mars.

First, note the different colors north and south of the ridgeline. According to the science team’s understanding of what these colors mean [pdf], the orange-red to the north suggests dust, while the bluish-green to the south suggests coarser materials, such as rocks and sand. Though frost and ice are generally bluer, such things are generally found on the pole-facing slopes where there is less sunlight. Thus the bluish-green material to the south is unlikely to be ice or frost, though this is not impossible, as the picture was taken in the winter and the latitude is 35 degrees north.

Why however is there such a dichotomy of rocks, sand, and dust between the north and south slopes? And if frost and ice, why is it more prominent to the south, when it should instead be more prominent to the north?

Other mysteries: Is the circular depression on the ridgetop an impact crater or a caldera? If the latter, this suggests the mound is some kind of volcano, likely mud, though lava is not excluded. If so, however, why is there no caldera on top of the ridge to the south?

The location, as shown in the overview map below, reveals other puzzles.

Virgin Orbit’s cash problems continue

9:25 am

Because of endless delays getting a regulatory approval of a launch in the United Kingdom, Virgin Orbit has been unable to complete the 4 to 6 launches in 2022 that it had planned, and is thus experiencing serious cash shortages that has now caused it to cancel plans to sell “additional securities.”

Virgin Orbit reported third quarter revenues of $30.9 million, which exceeded the zero revenues reported in Q3 2021. The company’s net loss was $43.6 million, which was higher than the $38.6 million loss in Q3 2021.

While costs and losses have mounted, Virgin Orbit has experienced delays in increasing its launch rate. The company had planned to conduct four to six launches this year. Today, the total stands at only two with just over a month left in 2022.

Virgin Orbit’s third launch was originally scheduled to take place in last August from Spaceport Cornwall in England. The company is still awaiting a license from the UK government that would allow the launch to take place. It is the first time the government has licensed both an orbital launch and a spaceport, so the process it taking longer than anticipated.

The company had not only ramped up production of its LauncherOne rocket in anticipation of an increased launch rate, it also purchased two more 747s to act as the rocket’s first stage carrier. Those actions however were based on the ability to increase the launch rate, which has been stymied since the summer by Great Britain’s Civil Aviation Authority, which can’t seem to issue permission for Virgin Orbit to launch from a runway in Cornwall.

The canceled sale of securities appears part of the entire investment deal near the end of 2021. The cash shortages and this deal also appear connected to the decision by Richard Branson’s Virgin Group to invest $25 million in Virgin Orbit earlier this month.

Virgin Orbit officials say they intend to double their launch rate in 2023. I suspect that they have to. It is now sink or swim.

China sets new annual record with launch of manned Shenzhou-15 to space station

9:02 am

China today successfully used its Long March 2F rocket to launch three astronauts on a six month mission to its Tiangong-3 space station, setting a new annual national record for launches in a single year.

China’s previous high of 52 successfully launches was achieved last year. This launch, with about five weeks left in the year, is its 53rd in 2022.

This mission will also be the first on Tiangong-3 where there will be an overlap of two crews, with six people occupying the station for a short while.

The leaders in the 2022 launch race:

54 SpaceX
53 China
20 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 78 to 53 in the national rankings, while trailing the rest of the world combined 83 to 78.

A ghost goddess in space

Ghost goddess in space
Click for original image.

Cool image time! The image to the right, cropped, rotated, reduced, and enhanced to post here, is without doubt one of my favorite objects that the Hubble Space Telescope has photographed over the decades. This new image combines imagery obtained by earlier Hubble cameras and the newer cameras installed in 2009.

The delicate sheets and intricate filaments are debris from the cataclysmic death of a massive star that once lived in the Large Magellanic Cloud, a small satellite galaxy of the Milky Way. DEM L 190 — also known as LMC N49 — is the brightest supernova remnant in the Large Magellanic Cloud and lies approximately 160 000 light-years away from Earth in the constellation Dorado.

What makes this supernova remnant so visually appealing to my eye is its ghostly resemblance to a woman’s face, her hair blowing freely to the right. The original 2003 Hubble picture, shown below, has been the desktop image of my computer for almost two decades.

Dragon freighter docks with ISS

9:22 am

ISS as of November 28, 2022

Capitalism in space: An unmanned Dragon freighter successfully docked with ISS yesterday, bring with it 7,700 pounds of cargo, including two new solar arrays for the station.

Two International Space Station Roll-Out Solar Arrays, or iROSAs, launched aboard SpaceX’s 22nd commercial resupply mission for the agency and were installed in 2021. These solar panels, which roll out using stored kinetic energy, expand the energy-production capabilities of the space station. The second set launching in the Dragon’s trunk once installed, will be a part of the overall plan to provide a 20% to 30% increase in power for space station research and operations.

These arrays, the second of three packages, will complete the upgrade of half the station’s power channels.

The graphic to the right shows the station as of today, with six different spacecraft docked to six different ports. No wonder there is a significant limit to the number of private missions that can fly to ISS. The needs of the station, as dictated by the international partnership of governments that run it, too often fill those ports.

This limitation will begin changing when Axiom launches its first module for ISS in about two years, followed soon thereafter by the launch of a number of other private independent stations by different American companies.

Rocket startup Agnikul Cosmos opens first commercial launchpad in India

9:09 am

Capitalism in space: The Indian rocket startup Agnikul Cosmos has completed construction on the first privately owned launchpad in India, with the first suborbital launch planned before the end of this year.

Agnikul’s infrastructure comprises a launchpad and a Mission Control center 4 kilometres away, both within ISRO’s facilities on the island located off the coast of Chennai. The space pad was designed by Agnikul, constructed over two months, and is a part of the MoU signed between ISRO and Agnikul (among other space startups) under the new regulatory authority IN-SPACe’s first batch of support projects for private companies from ISRO.

Currently, it is capable of launching Agnikul’s rocket, the Agnibaan. [emphasis mine]

The first test launch is apparently not going to be orbital, but a technology test of the launch pad, its fueling facilities, and the 3D-printed engine Agnikul has built for Agnibaan.

The highlighted words once again note the effort by the Indian government to emulate the U.S. policy in the past decade to transition from a government-run space program to a privately-run competing and chaotic space industry. This MoU (memorandum of understanding) probably resembles the first space act agreements NASA issued to SpaceX and Orbital ATK. The agreements gave private companies aid and assistance, but the companies retained full ownership of what they build, and were left free to design things as they saw fit, not as the government dictated.

That two different Indian companies, Agnikul and Skyroot, are on the verge of their first orbital launches signals that this policy is succeeding. Agnikul has tested its engines and built its launchpad. Skyroot has completed its first suborbital launch.

SpaceX’s Falcon 9 successfully launches Dragon freighter to ISS

12:34 pm

SpaceX today successfully used its Falcon 9 rocket to launch a Dragon freighter to ISS.

The first stage landed successfully on a drone ship in the Atlantic, completing its first flight, only the third time this year out of 54 total launches that SpaceX had to use a new first stage. All other launches were with reused boosters.

The Dragon freighter is scheduled to dock with ISS at 7:30 am (Eastern) tomorrow.

The leaders in the 2022 launch race:

54 SpaceX
52 China
19 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 78 to 52 in the national rankings, but trails the rest of the world combined 81 to 78.

Smallsat rocket startup Phantom Space gets NASA launch contract

8:32 am

The smallsat rocket startup Phantom Space has been awarded a NASA launch contract designed to encourage new companies.

Phantom Space Corp. announced today it has been awarded four new NASA task orders to launch CubeSat satellites into space as part of the new VADR contract. NASA’s VADR missions (for Venture-class Acquisition of Dedicated and Rideshare) missions intend to meet the agency’s needs for NASA payloads while also fostering the development of new launch vehicles from both emerging and established launch providers. VADR increases access to space by significantly reducing costs using less NASA oversight to achieve lower launch costs with payloads that can accept a higher risk tolerance.

…The company plans to stage the first space flights in 2024, and the NASA CubeSats will be among the first payloads. Two will be onboard the second Phantom flight, and the other two will be on the fourth flight. The CubeSat launches for NASA will occur at the Vandenberg Space Force Base’s Space Launch Complex 8.

The Tucson-based company’s Daytona rocket will use ten Hadley engines being built by the rocket engine startup Ursa Major.

One of Phantom’s founders, Jim Cantrell, gave me a tour of their facility in May. Cantrell had been head of the rocket startup Vector, and when that failed because its own engines were underpowered, formed Phantom. Phantom however does not build its own engines but gets them from Ursa Major, a company founded by former SpaceX engineeers.

Orion enters retrograde lunar orbit

4:17 pm

Engineers today successfully completed an engine burn that put Orion into the retrograde lunar orbit in which it will remain for the next week.

Due to the distance of the orbit, it will take Orion nearly a week to complete half an orbit around the Moon, where it will exit the orbit for the return journey home. About four days later, the spacecraft will harness the Moon’s gravitational force once again, combined with a precisely timed lunar flyby burn to slingshot Orion onto its return course to Earth ahead of splashdown in the Pacific Ocean on Sunday, Dec. 11.

As of now all systems seem to be working as intended.
