Update on Blue Origin activity at Cape Canaveral

9:16 am

Link here. Much of the activity the article describes has to do with preparing for a first launch of Blue Origin’s New Glenn rocket, suggesting that it might finally take place in 2024 as presently planned.

In fact, the activity also suggests that the company intends to attempt to recover its first stage from a landing ship in the ocean on that first flight.

In early October, a large Liebherr mobile crane was delivered to Port Canaveral to support Blue Origin’s continuously growing presence on the Space Coast. Once New Glenn begins flying, this crane will assist recovery operations by lifting the 57.5-meter-tall first stage from the landing vessel and onto shore.

More recently on Nov. 27, a large jig on a barge was towed into Port Canaveral and proceeded to be offloaded by Blue Origin’s new crane. This custom-made structure appears to be a stand to support New Glenn first stages after being offloaded from its landing vessel. Various work platforms will allow crews to inspect the boosters in different locations before the booster itself is transported back to the factory, or the future refurbishment facility which is still yet to be built.

It also appears the company has built a full scale test version of New Glenn to allow testing of all operations prior to launch.

Keep your fingers crossed. With former CEO Bob Smith gone, Blue Origin might finally be coming back alive at last.

Russia launches Progress to ISS

9:09 am

Russia early this morning successfully launched a Progress freighter to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The rocket’s core stage, strap-on boosters, and second stage crashed in the standard drop zones the Russians have used since the launch of Sputnik in 1957. It is unclear how close to inhabited areas any of these are.

The leaders in the 2023 launch race:

87 SpaceX
53 China
16 Russia
7 Rocket Lab
7 India

American private enterprise still leads China in successful launches, 99 to 53, and the entire world combined 99 to 85. SpaceX by itself still leads the entire world (excluding other American companies) 87 to 85.

SpaceX however has two launches scheduled for today, one at Vandenberg at 10:04 am (Pacific) and the second at Cape Canaveral at 11 pm (Eastern). The links go to the live streams.

Lava-filled Martian crater

12:56 pm

Lava-filled Martian crater
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 10, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the northeast corner of an unnamed 7-mile-wide crater, located near the equator in the dry Martian tropics.

The MRO science team labels this “crater and lava fill”, suggesting that the crater interior is filled with lava material. The nature of that crater floor reinforces this conclusion, as it is relatively smooth and does not have rough aspects of glacial material found in craters in the mid-latitudes. Instead, it looks like a frozen lake of lava that has the peaks of mostly buried features poking up at various spots.

What makes this crater interesting however are the gullies on the northern interior rim. Gullies on Mars are normally thought to be associated with some water-frost-ice process, probably seasonal, where the thaw-freeze cycle causes small collapses and avalanches. Yet, this crater is almost at the equator, in a very dry region where no evidence of near-surface ice is found. Gullies here suggest the hypothesis for explaining the gullies on Mars have not quite solved the mystery.

ESA admits Ariane-6 will not fly until the summer of 2024

12:27 pm

The European Space Agency today announced that the first launch of its new Ariane-6 rocket will not take place in the first quarter of 2024 and is now targeting a summer launch instead.

At a Nov. 30 briefing, ESA Director General Josef Aschbacher announced a launch period for the inaugural Ariane 6 flight of June 15 through July 31. A more precise launch date will be provided after qualification reviews in the spring of 2024. The announcement comes after a Nov. 23 long-duration test firing of a model of the core stage of the Ariane 6. That test, conducted on the launch pad at Kourou, French Guiana, was intended to simulate a full burn by the core stage.

The delay is not significant by itself, but in the large scheme of things it continues for another few months Europe’s lack of any large rockets to launch any payloads. The original plan when the Ariane-6 project was announced in the mid-2010s was for it to begin flights in 2020 with a several year overlap as the Ariane-5 was retired around 2023. As planned, the last launch of Ariane-5 occurred this summer, but Ariane-6 is now four years behind schedule.

At the moment the rocket has one more major test required, an upper stage static fire test scheduled for December. That test must go well for this new schedule to go forward, which will include a second Ariane-6 launch in 2024 followed by “as many flights as possible” in 2025. ESA hopes to do 9 to 10 Ariane-6 launches per year, most to fulfill the contract of 18 launches with Amazon to put some of its Kuiper satellite constellation into orbit.

Real pushback: Corporate America eliminating college degree requirements for new hires

11:35 am

Increasingly viewed at useless educational institutes
Increasingly viewed at useless educational institutes

According to a new survey of 800 American companies, about half say they have now dropped their requirement that new employees have a college degree, with some businesses replacing this requirement with actual apprenticeship programs.

For example, Accenture launched an apprenticeship program in 2016 through which it has since hired 1,200 people, CNBC reported. Some 80 percent of those people joined the company without a four-year-degree.

Earlier this year, the company expanded the program with the goal of filling 20 percent of its US entry-level roles. ‘A person’s educational credentials are not the only indicators of success, so we advanced our approach to hiring to focus on skills, experiences and potential,’ CEO of Accenture North America, Jimmy Etheredge, told the outlet.

According to the report, 45% of all businesses surveyed intend to eliminate college degree requirements next year, while 55% say they have already done so. Major companies like Walmart, IBM, Facebook, Intel, and Microsoft have been public about their shift away from college degree requirments, while others like Google and Apple have done so more quietly.

According to this survey [pdf] from the Burning Glass Institute, which analyzed trends across 51 million job postings, this trend appeared to begin before the Wuhan panic, was accelerated significantly by it, but has continued subsequent. This short quote from that report however says it all:

Communications resume with Mars orbiters and rovers

9:06 am

It now appears that communications have resumed between Mars and the Earth, the planets having moved do that the Sun is no longer in between. From an update by the Curiosity science team today:

Mars has just emerged from its solar conjunction period, when sending commands to all Mars spacecraft was not safe for three weeks since the Red Planet was behind the Sun as seen from Earth. During that time, Curiosity followed a long plan of instructions covering Sols 4004-4022 which were uploaded to the rover during the week of October 30. The early word on is that the rover weathered the long blackout period just fine.

During the black-out the rovers had continued to upload data to the orbiters above, and some of that data was relayed back to Earth this past weekend, though the relay was “spotty” with some data packages lost.

Communications have now cleared up, and so we should expect both Curiosity and Perseverance to resume full operations again.

Hubble in safe mode due to gyroscope problem

8:58 am

One of the three working gyroscopes (three have already failed0 on the Hubble Space Telescope experienced repeated problems in mid-November, and has now put the telescope in safe mode while engineers trouble-shoot the problem.

Hubble first went into safe mode Nov. 19. Although the operations team successfully recovered the spacecraft to resume observations the following day, the unstable gyro caused the observatory to suspend science operations once again Nov. 21. Following a successful recovery, Hubble entered safe mode again Nov. 23.

The team is now running tests to characterize the issue and develop solutions. If necessary, the spacecraft can be re-configured to operate with only one gyro. 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 fluctuations. Hubble uses three gyros to maximize efficiency, but could continue to make science observations with only one gyro if required.

The long term plan when the telescope only has two working gyros, assuming no improvised maintenance mission is flown to Hubble to give it new gyroscopes, is to work with only one (treating the second as a back-up) in order to extend the telescope’s life as long as possible.

And though it is true that Hubble could continue to do science with only one gyro, images from that point will likely not be as sharp, and thus will end more than three decades of imagery that changed our perception of the universe.

The Chinese 2-meter Xuntian optical space telescope, now scheduled for launch in 2025, will likely then replace Hubble as the world’s top optical telescope. American astronomers better start learning Chinese, assuming China even allows them access. They will not have a right to complain, however, as it was their decision to not build a Hubble replacement, in their 2000, 2010, and 2020 decadal reports.

Thick windblown ash in Mars’ largest mountain region

12:35 pm

Thick windblown ash near Mars' largest volcano
Click for original picture.

The cool image to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 1, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists label as “Erosional Features on Olympus Mons.”

What is eroding? Based on the picture itself the first guess is volcanic ash, as these features strongly resemble the many features seen in the Medusae Fossae Formation, the largest volcanic ash field on Mars — about the size of the subcontinent of India.

Medusae however is many thousand miles away, and is not apparently related to any specific volcano. These features are instead directly linked to Olympus Mons, the largest known volcano in the solar system. However, much of the terrain for many hundreds of miles around Olympus is covered with flood lava, which was deposited and hardened quickly to form smooth featureless plains that have resisted much erosion over the eons. Here the terrain is clearly eroded, which suggests that if the material here is volcanic, it was laid down not by flood lava but by falling ash that got compressed but was easily friable and could be blown away by the winds of Mars’ thin atmosphere.

Japan’s space agency JAXA was hacked this summer

10:12 am

According to officials of Japan’s space agency JAXA, its computer system was hacked this summer but only learned of that break-in recently.

The illegal access is believed to have occurred around summer, but JAXA was unaware of the attack until the police contacted the agency, according to the sources. A full investigation was launched after JAXA reported the cyber-attack to the Education, Culture, Sports, Science and Technology Ministry, which has jurisdiction over the agency.

Although no large-scale information leakage has been confirmed at this stage, an official related to JAXA said: “As long as the AD server was hacked, it was very likely that most of the information was visible. This is a very serious situation.”

Earlier hacks to JAXA’s systems have also occurred in 2016 and 2017, with the culprits identified as working under the direction of the Chinese military. It is very likely that China is involved this time as well. China has previously been identified as the perpetrator of hacks of JPL from 2009 to 2019, during which much of JPL’s files on its planetary missions was stolen. It was thus no surprise when later Chinese planetary missions looked like upgraded copycats of those missions.

Why China is attempting to steal anything from Japan’s space program is puzzling however, considering its recent failures. If anything, China’s space program is presently far more advanced than Japan’s, and it should be Japan trying to steal from China.

NASA to fly Indian astronaut to ISS next year

9:52 am

During meetings in India between NASA and ISRO officials, instigated by administrator Bill Nelson’s visit this week, the mission details for the flight of an Indian astronaut to ISS in 2024 are now being worked out.

A Nasa delegation led by Nelson held a meeting with minister of state for science & technology Jitendra Singh on Tuesday. “I had a discussion with the minister on what the Indian astronaut would do on the space station. And the two of us talked about the fact that things that are important to India in scientific research, the Indian astronaut ought to have that as a choice to do. If there is a particular part of research that he or she would be interested in, then I want to encourage that,” Nelson later said at a media interaction. “Nasa will help train the Indian astronaut to fly to ISS by end of 2024. Those details are being worked out. Indian Space Research Organisation (Isro) will announce that,” Nelson said.

Though this plan for NASA to fly Indian astronaut to ISS next year was first announced in June, it was overshadowed by India’s decision at that time to sign the Artemis Accords.

It is also important to recognize that the real arrangements are all being done by others, that Nelson and the India government officials are merely there to get their faces on television.

If this flight happens as planned, next year could be very exciting for India’s manned space program, since it also hopes to fly its own manned mission at that time.

SpaceX buys the company that makes its Dragon parachutes

9:38 am

According to a Florida bankruptcy filing dated November 22, 2023, SpaceX has purchased for $2.2 million Pioneer Aerospace, the company that has been manufacturing the parachutes used by its Dragon cargo and manned capsules.

Apparently SpaceX bought the company in order to make sure its parachutes would still be available. This purchase also brings that operation into SpaceX itself, so that the company is no longer dependent on an outside vendor. Since its early days SpaceX has attempted to build as much as possible in-house, and this buy follows that policy.

Dragonfly mission to Titan delayed by a year because of budget shortfalls

9:26 am

Even as NASA gave engineers approval to move forward on building the helicopter set to fly on the Dragonfly mission to the Saturn moon Titan, it also revealed that the mission’s launch has been delayed by at least one year because of budget shortfalls.

In a presentation at a Nov. 28 meeting of NASA’s Outer Planets Assessment Group (OPAG), Lori Glaze, director of NASA’s planetary science division, said agency leadership decided to postpone formal confirmation of the mission earlier this month, a milestone where the agency sets an official cost and schedule for the mission.

The delay in confirmation by NASA’s Agency Program Management Council (APMC), she said, is based on uncertainty about how much money will be available for the mission and other parts of NASA’s planetary science portfolio given broader budget pressures on the agency. “Because of these incredibly large uncertainties in FY ’24 and FY ’25 funding and budgets, the decision was made at that APMC to postpone the official confirmation,” she said.

The launch had been scheduled for 2027. When it will launch now is unclear.

Apparently (and not surprising since this is a NASA project) the mission is beginning to cost more than originally predicted. Furthermore, this shortfall is enhanced by the cost overruns from the Mars Sample Return mission. In fact, it appears that these cost overruns are impacting NASA’s entire planetary program, causing delays on many smaller missions in order to fund Mars Sample Return and the Europa Clipper mission (set to launch next year). Just as Webb wiped out most of NASA’s astrophysics missions in the 2000s and 2010s, this handful of big planetary missions is wiping out most of NASA’s planetary program.

The announced delay is also a typical NASA’s negotiating tactic with Congress, trying to pressure elected officials to cough up more money. For decades NASA would announce the need for crippling cuts to major and popular science projects unless Congress allocates it more cash for its most expensive projects, and for decades Congress has gladly done so. No one ever asks whether those expensive projects might be better off redesigned, or cancelled.
