Problems fixed with next Russian ISS module

9:58 am

According to a report from Russia today, the problems with contamination in the fuel tanks for Russia’s next module to ISS, originally scheduled for launch in 2013, have finally been dealt with, and the launch can go forward.

“Original tanks will be used. They had successfully undergone all trials, all problems with them have been fixed. We are now receiving relevant documents,” one of the sources told TASS. He said the module is currently at the Khrunichev center, and the timeframe of finishing touches to it is now being coordinated.

Another source in the industry told TASS that although Nauka tanks were initially designed for multiple use, “they will be used only once – for the module’s docking with the space station.”

In other words, they weighed their options, and decided that limiting the tanks to only one use was better than trying to replace them. I suspect this is because the replacement was both very difficult and would have also delayed the launch so much that ISS might not have been orbit any longer.

A new launch date has not been announced. Previously Roscosmos had indicated 2020 as the date.

Starlink satellite launches to dominate SpaceX’s 2020 launch schedule

9:39 am

According to statements made by an SpaceX official on September 10, in 2020 the bulk of all the company’s launches will be to launch satellites in its Starlink internet constellation.

SpaceX plans as many as 24 launches next year to build out the company’s Starlink network to provide broadband Internet service from space, following up to four more Starlink missions before the end of this year, according to SpaceX’s chief operating officer.

The rapid-fire launch cadence for SpaceX’s Starlink fleet will take up the majority of the company’s launch manifest next year with a series of missions taking off from Florida’s Space Coast, adding new nodes to a network that could eventually contain nearly 12,000 small satellites.

If they complete this schedule, then SpaceX could complete as many as 40 launches in 2020, when all its other backlogged launches are included.

At the same time, this schedule indicates the slowdown in the launch of geosynchronous satellites, as predicted by many in the launch business. The communications industry appears to be shifting to lower orbit constellations and smaller satellites, as illustrated by Starlink itself.

LRO fails to spot Vikram on Moon

9:32 am

Despite successfully taking high resolution images of the area on the Moon where it is thought India’s Vikram crash-landed two weeks ago, the Lunar Reconnaissance Orbiter (LRO) science team has been unable to identify it in those images.

LRO’s Lunar Reconnaissance Orbiter Camera instrument, or LROC, imaged the intended south pole touchdown site for the lander, which is called Vikram, as planned yesterday (Sept. 17), Aviation Week’s Mark Carreau reported. But “long shadows in the area may be obscuring the silent lunar explorer,” Carreau wrote.

“It was near dusk as the region prepares to transition from a two-week lunar day to an equally long lunar night, so shadows covered much of the region, and Vikram may not be in the LROC’s field of view,” Carreau wrote, citing a NASA statement.

This means that they will simply have to try again during a later orbit. Eventually the lighting conditions will be right, and LRO will photograph Vikram.

House hearing, and budget, raises doubts about 2024 Moon landing

9:27 am

Two events yesterday increased the likelihood that the Trump administration’s effort to complete a manned Moon landing by 2024 will not happen.

First, at hearings yesterday before the House Science, Space, and Technology (SS&T) Committee, not only did a top NASA official express skepticism about the 2024 date, several key Democratic lawmakers added their own skepticism about the entire project.

Then, the Democratically-controlled House released a draft continuing resolution which included none of the extra $1.6 billion requested by the Trump administration for the 2024 Moon mission.

At the first link there is much discussion about the issues of Gateway, of using commercial launchers instead of SLS, of funding, and of the endless delays for SLS, of the management problems at SLS/Orion/Gateway. All these issues illustrate the hodgepodge and very disorganized project design that has represented SLS/Orion/Gateway from the beginning. SLS/Orion was mandated by Congress, with no clear mission. Gateway was tacked on later by NASA and the big space contractors building SLS (Boeing) and Orion (Lockheed Martin), with lobbying help from other international space agencies who want a piece of the Gateway action. None of it ever had a clear over-arching goal or concept related to the actual exploration of space. All of it was really only designed to justify pork spending in congressional districts.

As much as the Trump administration wants it, I do not see a path for its 2024 Moon landing. Congress, as presently structured, will not fund it, and SLS and Gateway are simply not the projects designed to make it happen.

The confusion at the hearings over Gateway also suggests that if this project gets going, it will only serve to drive a nail into the coffin of all American manned exploration, as run by our federal government. Too many vested interests are fighting over this boondoggle. In the end I think they will rip it apart and then reshape it into a Frankenstein monster.

The only hope for a real American vibrant manned space effort in the near future still appears to me to reside in the private sector’s own manned projects, which right now means SpaceX and its Starship.

Israel election produces uncertainty again

7:05 pm

Yesterday’s election in Israel, called because the leading block led by Benjamin Natanyahu could not form a majority coalition after the last election in May, has apparently resulted in a similar result.

I am still researching what I think might be the causes behind this on-going situation in Israeli politics. The article at the link describes some of the negotiations between the various factions that might produce a new Natanyahu government, or not.

My sense is that this situation all begins with the special exemptions to military service that still remain for the orthodox, or haredi community. The reason Natanyahu could not form a coalition in May was that one of his expected partners, a generally conservative but secular party dubbed Yisrael Beytenu, wanted a commitment to remove those remaining exemptions, and Natanyahu couldn’t get the various religious parties to go along.

As result, it appears that the religious parties lost some support in yesterday’s election, making it even harder for Natanyahu to make a deal.

I have asked some of my relatives in Israel if my analysis here makes sense, and am waiting a response.

Either way, it appears that no one is going to have an easy time putting together a government in Israel.

Update: This story from Israel tonight provides some clarity about the position of Yisrael Beytenu, stated by its chairman, Avigdor Liberman. In it he outlines his party’s demands, which do not just involve the special military exemptions for the haredi but also the power the orthodox have held in Israel over other issues.

“We will not concede on the passing of the Draft Law, as it was originally written, we will not concede on repealing the Supermarket Law, we will not concede on public transportation on Shabbat, we will not concede on civil marriages, and the introduction of core studies into haredi education. These are the conditions, and until we hear things in that spirit – there’s nothing to talk about.”

All of these cited issues involve the effort by the religious parties to exert more control. For example, the Supermarket Law, passed in 2018, gave the national government power to determine whether local businesses could be open on Shabbat (Saturday, the day of rest), instead of local bylaws. Similarly, issues of marriage and education all involved a conflict between the secular and orthodox communities.

Either way, Liberman will only join a coalition of all the secular parties, excluding both the Jewish religious parties and the Arab parties (dubbed the Joint List). To do this would require the two largest parties, the conservative Likud, led by Natanyahu, and the more liberal Blue and White, led by Benny Gantz to partner. Everything I have read suggests this will not be possible, as long as Natanyahu leads Likud.

Fifty years of failed climate predictions

4:12 pm

Link here. From the abstract:

Modern doomsayers have been predicting climate and environmental disaster since the 1960s. They continue to do so today.

None of the apocalyptic predictions with due dates as of today have come true.

What follows is a collection of notably wild predictions from notable people in government and science. More than merely spotlighting the failed predictions, this collection shows that the makers of failed apocalyptic predictions often are individuals holding respected positions in government and science.

While such predictions have been and continue to be enthusiastically reported by a media eager for sensational headlines, the failures are typically not revisited.

Many of these doomsday predictions have been previously documented by Tony Heller at his Real Climate Science website.

Much of the fault of these failed predictions falls to the media, which blindly hawks these predictions as if they were solid science, when most were merely political activism falsely dressed up as science. Predictions like this should almost never make the news. What should count are actual results, and data, showing something that is actually happening.

Unfortunately, our mostly liberal press has since the 1980s instead decided to team up with climate activists to push their agendas. Worse, though the examples at the link end in 2014, this journalistic malpractice still goes on today. Only three weeks ago Heller posted this story, Greenland Propaganda Meltdown, noting the errors and false claims in an August 20, 2019 Los Angeles Times that claimed “Greenland’s glaciers are melting.”

IG had recommended criminal prosecution of Comey

12:22 pm

The law is only for little people: In testimony today before Congress, Justice Department inspector general Michael Horowitz revealed that he had recommended criminal prosecution earlier this year against former FBI director James Comey.

The Justice Department however declined to follow through, essentially letting Comey off the hook.

In the past few weeks there have been many rumors about more criminal referrals by Horowitz in connection with his investigation into the illegal use of the FISA court by the FBI and Obama Justice Department to initiate spying operations on Trump during the 2016 presidential campaign. The conservative press has made much of those rumors.

To my mind, the rumors mean squat, just as Horowitz’s recommendation here against Comey. Until these corrupt officials are actually indicted, the IG can say whatever he wants, but nothing has been accomplished, and future federal employees will know that they can attempt a coup against legally elected lawmakers and face no consequences.

New findings from Rosetta: Bouncing boulders and collapsing cliffs

10:13 am

cliff collapse on Comet 67P/C-G

In reviewing the large image archive taken by Europe’s Rosetta probe while it orbited Comet 67P/C-G from 2014 to 2016, scientists have found more evidence of changes on its surface during its closest approach to the Sun, including a bouncing boulder and the collapse of large cliff.

The image on the right, reduced to post here, shows both wide (top) and close-up (bottom) views of the cliff collapse.

“This seems to be one of the largest cliff collapses we’ve seen on the comet during Rosetta’s lifetime, with an area of about 2000 square metres collapsing,” said Ramy, also speaking at EPSC-DPS today. … “Inspection of before and after images allow us to ascertain that the scarp was intact up until at least May 2015, for when we still have high enough resolution images in that region to see it,” says Graham, an undergraduate student working with Ramy to investigate Rosetta’s vast image archive.

“The location in this particularly active region increases the likelihood that the collapsing event is linked to the outburst that occurred in September 2015.”

These finds are only a sample of a number of similar discoveries since the end of the mission, as scientists pore through the more than 76,000 images in the Rosetta archive.

Hayabusa-2 completes rehearsal for MINERVA-II drop

9:58 am

Hayabusa-2 has successfully completed its rehearsal for its planned drop of its last MINERVA-II bouncer/rover, releasing two reflective targets in order to track how they spiral down to the surface of Ryugu.

Hayabusa 2’s cameras will track the movement of the two navigation aids as they fly in space around Ryugu over the next several days. Scientists expect Ryugu’s tenuous gravity will pull the target markers to the asteroid’s surface within a week.

The release of that last bouncer is now expected in about a month. After spending time obtaining the data from that drop, Hayabusa-2 will then head back to Earth by the end of the year.

Roscosmos knows but will not disclose cause of Soyuz drilled hole

9:53 am

According to a statement by Dmitri Rogozin, the head of Roscosmos, the Russians now know what or who caused the drillhole in a Soyuz capsule, found when air began to leak from ISS in August 2018, but they will not reveal that information.

What happened is clear to us, but we won’t tell you anything”, Rogozin said at a meeting with the participants of a scientific youth conference. … We may have some secrets”, he said.

I wonder if NASA will accept this decision. I also wonder why this doesn’t raise the hackles of NASA’s safety panel, which seems so willing to stall the launch of American manned capsules for far less worrisome safety reasons, thus forcing us to use Russia’s Soyuz capsule instead.
