Scientists publish papers describing largest Mars quake from May

1:56 pm

Location of May quake

Though news of the largest quake so far detected by InSight on Mars, magnitude 4.7, was released in May, this week the science team published two papers describing the quake itself and what they have learned from it. From the press release:

The waves from the record-breaking quake lasted about 10 hours — quite a while, considering no previous Marsquakes exceeded an hour.

It was also curious because the epicenter was close to but outside the Cerberus Fossae region, which is the most seismically active region on the Red Planet. The epicenter did not appear to be obviously related to known geologic features, although a deep epicenter could be related to hidden features lower in the crust.

Marsquakes are often divided into two different types — those with high-frequency waves characterized by rapid but shorter vibrations, and those of low-frequency, when the surface moves slowly but with larger amplitude. This recent seismic event is rare in that it exhibited characteristics of both high- and low-frequency quakes. Further research might reveal that previously recorded low- and high-frequency quakes are merely two aspects of the same thing, Kawamura said.

The green-dotted white patch on the map above marks the approximate location of this quake, east of where most of the previous larger quakes have been detected and under the Medusa Fossae Formation of volcanic ash. That no surface features appear to correspond to this quake, it is thought it was the result of a shift of underground features.

The first launch of China’s Zhuque-2 rocket ends in failure

1:31 pm

The first launch of China’s Zhuque-2 rocket, built by the pseudo-private company Landspace, ended in failure today when the upper stage had problems after separation of the first stage.

Apparent spectator footage posted on Chinese social media showed the rocket ascending into clear skies, trailed by white exhaust. While the first stage is understood to have performed well, separate apparent leaked footage suggests that issues affecting the rocket’s second stage resulted in the failure of the mission.

Data suggest an expected burn of the stage’s vernier thrusters, intended to carry the stage and payloads into orbit after a burn by the main engine, did not occur as planned.

If this launch had been successful, it would have made the Zhuque-2 rocket the first rocket to reach orbit using methane as a fuel, beating three different American companies, SpaceX, Blue Origin, and Relativity.

Relativity has been preparing for the first launch of its Terran-1 rocket since October, with a goal of launching before the end of the year. At the moment however no launch date is set, though the company’s CEO seems confident it will launch soon.

In addition, SpaceX has also been targeting the first orbital launch of its Starship/Superheavy rocket by the end of this year. As with Relativity, no launch date has been set.

The first launch of Blue Origin’s New Glenn rocket meanwhile is nowhere in sight, as yet. It was originally supposed to launch in 2020, but even now has four launches scheduled on its manifest for 2023. None however have been scheduled, and the first launch will likely slip to late in the year, if that soon.

Overview map
Click for interactive map.

The panorama above was taken by Curiosity’s right navigation camera today, December 14, 2022, looking down into Gediz Vallis, the giant slot canyon that the rover will use as its route up Mount Sharp.

The red dotted lines above and on the overview map to the right indicate approximately the planned route for Curiosity. The yellow lines indicate the approximate area covered by the panorama above.

At present the scientists are attempting to drill into the marker band on which Curiosity sits. This marker layer is visible at many places at about the same elevation on all sides of Mount Sharp’s flanks. The white arrows indicate other examples of it in this overview map. It generally appears smooth and flat, which suggests it is made of a harder substance more resistant to erosion. That hardness was confirmed when Curiosity’s first drill attempt into it last week failed. The scientists are now trying again.

Juno snaps heat image of Jupiter’s volcano-covered moon Io

10:24 am

Io's volcanoes
Click for full image.

The image to the right, cropped and reduced to post here, was taken on July 5, 2022 by one of the infrared instruments on the Jupiter orbiter Juno of the moon Io, known for having many many active volcanoes.

This infrared image was derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard Juno. In this image, the brighter the color the higher the temperature recorded by JIRAM.

Each bright spot is an active volcano, some of which have been in the past photographed during eruptions. In fact, the first such photo was taken in March 1979 by the Voyager-1 spacecraft just after its fly-by of Jupiter, and was the first time any active volcano outside of Earth had ever been identified.

What made that discovery more profound was that only a week earlier scientists had published a paper predicting active volcanoes on Io, caused by the strong tidal forces from Jupiter’s gravity.

Since then planetary scientists have been studying Io’s volcanism repeatedly, tracking the evolution of specific volcanoes over time as they erupt and then become dormant.

NASA, Boeing, and the UAE negotiating partnership for building Lunar Gateway airlock

9:26 am

According to press reports in the United Arab Emirates (UAE), that country is negotiating with NASA and Boeing on a partnership to build an airlock module for NASA’s Lunar Gateway Moon space station.

US aerospace company Boeing said it has held discussions with Emirates officials about the UAE providing an airlock module on the Lunar Gateway. This is an airtight room that astronauts would use to enter and exit the space station.

John Mulholland, vice president and International Space Station programme manager at Boeing, told The National that the company was “actively working” with the UAE on the concept and design.

It appears the UAE is offering to pay Boeing to build it for NASA, and would expect in exchange a larger share in the use of the station.

If this deal works out, the UAE will essentially replace Russia as a Gateway partner. Russia had signed an agreement with NASA in 2017 to build that airlock, but that deal is now null and void following the Russian invasion of the Ukraine and its desire to partner with China instead.

For the U.S., this is a win-win, since it will now be an American company building the airlock, not Russia.

Rwanda and Nigeria to sign Artemis Accords

9:13 am

Rwanda and Nigeria have become the first two African nations to sign te Artemis Accords, bringing the number of signatories to this American-led alliance to 23.

Neither Nigerian nor Rwandan officials described in detail any plans to participate in Artemis at the signing ceremony, but at the Secure World Foundation event, a State Department official said that is not a condition for signing the Accords.

“We continue to encourage all responsible spacefaring nations to sign the Accords, and we also encourage countries that are just developing their space sector to also consider signing,” said Kristina Leszczak of the State Department’s Office of Space Affairs. “We stress that interested countries do not need to come to the table with existing space capabilities or even near-term plans to contribute to Artemis. We find this opens the conversation up to a much more diverse group.”

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

The accords, bi-lateral agreements between each nation and the U.S., were designed during the Trump administration to emphasize the rights of private investors in space and thus do an end-around of the Outer Space Treaty. Under the Biden administration it is no longer clear if that remains the goal. The existence of a signed alliance led by the U.S. and the capitalistic west however gives the U.S. the political force to protect those rights, assuming the American government is interested in the future in doing so.

Hakuto-R sends first image back to Earth

9:04 am

Hakuto-R's first released images
Go here and here for original images.

The private Hakuto-R lunar lander, owned and built by the Japanese-based company Ispace, is operating as planned and has sent back its first images from two different cameras.

The larger image to the right was taken by a camera on one of Canada’s payloads. It shows the Earth two minutes after launch, with the rocket’s upper stage acting as a frame. The inset, reduced to insert here, was taken 19 hours after launch by the lander’s main camera, and shows the Earth at night. Both images demonstrate that the spacecraft is stable and functioning perfectly.

The goals of the mission remain mostly engineering. Its focus is demonstrating first that Ispace’s lander can do what it says so that future customers will be confident buying payload space. Similarly, the payloads, such as the UAE’s Rashid rover, are doing the same thing.

Ariane 5 successfully launches three satellites

3:33 pm

Arianespace’s Ariane 5 rocket successfully launched two communications satellites plus a weather satellite today, leaving that rocket only two more launches left before it is permanently retired.

As this was only the fifth successful launch this year by Arianespace (representing Europe), the leader board in the 2022 launch race remains unchanged:

58 China
56 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 80 to 58 in the national rankings, but now trails the entire world combined 90 to 80.

The featureless volcanic ash plains of Mars

2:04 pm

The featureless volcanic ash plains of Mars

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken on September 10, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what appears to be a relatively featureless plain with a surface resembling stucco.

At -9 degrees south latitude, this is in the Martian dry equatorial regions. No ice or glaciers here. However, the consistent orientation of the knobs and hills suggest dunes and sand blown by prevailing winds, and that guess holds some truth. This location is deep within the Medusae Fossae Formation, the largest volcanic ash deposit on Mars, covering an area about as big as India, and believed to be the source of most of the red planet’s dust.

We are thus looking at thick layer of ash, its surface shaped over eons by the winds of Mars’ thin atmosphere.

NASA approves $1.2 billion asteroid-hunting space telescope

8:51 am

NASA has given the go-ahead to build NEO-Surveyor for $1.2 billion, more than twice the cost of its original proposal, to launch by 2028 and then look for potentially dangerous asteroids.

Notably, NEO Surveyor was earlier estimated to cost between $500 million and $600 million, or around half of the new commitment. The NASA statement said that the cost and schedule commitments outlined align the mission with “program management best practices that account for potential technical risks and budgetary uncertainty beyond the development project’s control.” Earlier this year, the project’s launch was delayed two years, from 2026, due to agency budget concerns.

The mission is designed to discover 90% of potentially Earth-threatening asteroids and comets 460 feet (140 meters) or larger that come within 30 million miles (48 million kilometers) of Earth’s orbit. The spacecraft will carry out the survey while from Earth-sun Lagrange Point 1, a gravitationally stable spot in space about 930,000 miles (1.5 million kilometers) inside the Earth’s orbit around the sun.

A prediction: It will cost more, and not launch on time. NASA’s decision to double the budget and delay the launch two years suggests it did not trust the JPL cost and time estimates. Based on most NASA-centered projects, however, it is likely the new numbers will still be insufficient.

Another space station company, ThinkOrbital, enters the competition

8:39 am

Though it failed to win a NASA contract to build its manned space station concept, the company ThinkOrbital has instead won small two research grants from the Space Force.

Earlier this year ThinkOrbital — with partners Redwire, KMI and Arizona State University — won two research contracts worth $260,000 under the U.S. Space Force Orbital Prime program for in-space servicing, assembly and manufacturing. Rosen said the plan is to refine the design concept for a space structure that could be used for debris removal and recycling.

“We’re working on a hub and spoke concept where smaller satellites would go out and gather the debris, bring it back to a central location, process it and we could either turn them into fuel or deorbit them,” said Rosen. “We could process debris at that hub, for example, and turn aluminum into aluminum powder that could be used for spacecraft fuel.”

ThinkOrbital is hoping to be selected for the next phase of Orbital Prime which could be worth up to $1.5 million.

This new concept would not be manned, but would instead be used by unmanned robots as service depot.

Bezos and Blue Origin to star in animated kids show

8:30 am

If you can’t build anything, than draw it! Jeff Bezos and his space company Blue Origin are now set to star in a kids animated show called “Blue Origins Space Rangers”.

The children’s series will feature the voices of Bezos, who founded his space tourism business Blue Origin in 2000, as well as “Good Morning America” co-host Michael Strahan, who was a passenger in December 2021 on Blue Origin NS-19 on a 10-minute spaceflight. Bezos took his supersonic joy ride to space in July 2021.

Nor is this the only show that Blue Origin is part of. A feature film set to release in 2023 will feature Blue Origin’s proposed (but not yet built) Orbital Reef space station.

All of this is fun and good, but it once again raises a question of focus. Is Bezos and Blue Origin really focused on building rockets and space stations, or it is mostly a pr operation for Bezos to sell himself? The overall lack of progress on its real rockets and space stations suggests the latter.
