LISA Pathfinder switched off

8:17 am

After a successful mission proving the technology for a full scale orbiting gravitational wave detector, LISA Pathfinder was shut off yesterday.

After 16 months of science measurements an international team deactivated the LISA Pathfinder satellite on the evening of the 18th of July 2017. The gravitational-wave laboratory in space powered down after receiving the last commands in the evening and circles the Sun on a safe parking orbit. LISA Pathfinder has tested key technologies for LISA, the future gravitational-wave observatory in space, and has demonstrated their operative readiness. LISA is scheduled to launch into space in 2034 as an ESA mission and will “listen” to the entire Universe by measuring low-frequency gravitational waves.

The idea is laudable, but for Europe to need another seventeen years to build and launch the full scale telescope is absurd. They now know what needs to be done. It should be relatively easy and quick to get it into orbit. And even if it isn’t easy, seventeen more years? Give me a break.

SpaceX competitors team up to try to block its satellite constellation

10:06 am

SpaceX’s main competitors in creating a satellite broadband industry have all filed objections with the FCC to the company’s planned 4,425 satellite constellation that is aimed at providing worldwide internet access.

SpaceX’s plan to provide global broadband internet access using thousands of satellites in low-earth orbit has come under fire from competitors, including Boeing and OneWeb, according to Space Intel Report. The argument is playing out in a series of filings with the Federal Communications Commission, focusing on SpaceX’s request for a temporary waiver from the FCC’s time limits for putting the satellite system into full operation.

The FCC would typically require the system to provide full coverage of U.S. territory within six years of a license being issued, but SpaceX says that’s not enough time to deploy the full 4,425-satellite constellation. Instead, the company proposes launching the first 1,600 satellites in six years, which would leave the northernmost part of Alaska without coverage when the deadline hits. Full U.S. coverage would be provided after the six-year deadline, SpaceX says.

In their own filings, competitors including OneWeb, SES/O3b and Intelsat are urging the FCC not to waive the six-year requirement, Space Intel Report said.

This is garbage, and demonstrates again why it is dangerous to give government too much power. Rather than compete by launching their own satellite constellations first, these companies want the FCC to put its finger on the scale to favor them and stop SpaceX. And I bet the decision will be made based not on what is right but on who gave the most campaign contributions to the right political party.

New adjustments to early satellite data confirm accelerating sea level rise

9:50 am

Well la-de-da! Surprise, surprise! New adjustments made by climate scientists to early satellite sea level data confirm an accelerating sea level rise.

The numbers didn’t add up. Even as Earth grew warmer and glaciers and ice sheets thawed, decades of satellite data seemed to show that the rate of sea-level rise was holding steady — or even declining.

Now, after puzzling over this discrepancy for years, scientists have identified its source: a problem with the calibration of a sensor on the first of several satellites launched to measure the height of the sea surface using radar. Adjusting the data to remove that error suggests that sea levels are indeed rising at faster rates each year. “The rate of sea-level rise is increasing, and that increase is basically what we expected,” says Steven Nerem, a remote-sensing expert at the University of Colorado Boulder who is leading the reanalysis. He presented the as-yet-unpublished analysis on 13 July in New York City at a conference sponsored by the World Climate Research Programme and the International Oceanographic Commission, among others.

Nerem’s team calculated that the rate of sea-level rise increased from around 1.8 millimetres per year in 1993 to roughly 3.9 millimetres per year today as a result of global warming. [emphasis mine]

This data correction might be true, but the highlighted phrases from this Nature article reveals two reasons why I do not trust these changes. First, there is the fact that this research and its adjustments to past data have not been published nor reviewed by anyone other than the people who agree with them. Second is the bald-faced completely impossible claim made that the sea level rise is caused by global warming. This work itself cannot possible determine what caused the sea level rise, as it is only observational, attempting to measure the rise, not study the cause. To make such a claim in this context is inappropriate.

Finally, it is this quote that makes me even more suspicious that this is garbage:

“As records get longer, questions come up,” says Gavin Schmidt, a climate scientist who heads NASA’s Goddard Institute for Space Studies in New York City. But the recent spate of studies suggests that scientists have homed in on an answer, he says. “It’s all coming together.”

Gavin Schmidt is the king of data tampering, constantly fiddling with the old climate data controlled by his institute so that it always cools the past and warms the present, thus increasing global warming not by actual observational data but by his personal whim. As this recent peer-reviewed review of Schmidt’s tampering noted, “The conclusive findings of this research are that the three GAST data sets are not a valid representation of reality.”

The sooner these fake scientists can be removed from positions of power over the datasets climate scientists need and use, the better.

Claremont McKenna College suspends students who led violent protest

10:54 pm

This is a victory. Claremont McKenna College has issued suspensions to seven students for their violent actions that threatened a pro-police speaker and anyone who wished to hear her lecture.

After reviewing video and photos of the blockade, the college has punished seven students: Three received one-year suspensions, two received one-semester suspensions, and two were put on conduct probation, the college’s announcement said. Officials also issued provisional suspensions of on-campus privileges to four non-students who appear to have played significant roles in the blockade, according to the statement.

“On the evening of April 6, a group of approximately 170 individuals from the Claremont Colleges and others outside our community organized, led, and executed a blockade of the Athenaeum and the Kravis Center. They breached the perimeter safety and security fence and campus safety line, and established human barriers to entrances and exits. These actions deprived many of the opportunity to gather, hear the speaker, and engage with questions and comments,” according to the statement. “… Sanctions were based on the nature and degree of leadership in the blockade, the acknowledgment and acceptance of responsibility, and other factors.”

This is also only a first step. As noted by the speaker, it is puzzling that with all the videotape records available, only 11 out of 170 individuals were identified for punishment.

Republican health tweak of Obamacare dead, Senate to vote for straight repeal

10:35 pm

This is a victory: The Republican leadership in the Senate, lacking the votes to pass their own version of Obamacare, have decided to instead go for full repeal.

Senate Majority Leader Mitch McConnell bowed to pressure tonight from conservatives — and President Trump — to bring up a straight repeal of most of the Affordable Care Act as the next step now that the Senate health care bill appears to be dead. It will be based on the repeal bill Congress passed in 2015, which then-President Barack Obama vetoed.

His statement: “Regretfully, it is now apparent that the effort to repeal and immediately replace the failure of Obamacare will not be successful. So, in the coming days, the Senate will vote to take up … a repeal of Obamacare with a two-year delay to provide for a stable transition period to a patient-centered health care system that gives Americans access to quality, affordable health care.”

McConnell’s hand was forced when two conservative senators, Mike Lee (R-Utah) and Jerry Moran (R-Kansas) announced earlier today that they would not vote for the bill.

This is what they should have done from the beginning. Granted, it is likely to fail because of Democratic opposition, but then it will be clear going into the next election who is standing in the way of fixing the problem. Had they passed any version of their turkey of a bill, the health insurance business would have continued to fail, but they would no longer have had clean hands. It would have become their problem, and it would have cost them votes in 2018.

Now, things will be clean, and we will get to see who really is on our side, from both parties. Expect several Republican senators especially to suddenly “evolve” and decide that they can’t go along with the very repeal they’ve voted for repeatedly in the past, because it might “hurt people.”

A map of Pluto

9:11 pm

Our best map of Pluto for many decades to come

The New Horizons science team has released the best maps of both Pluto and Charon possible from the images taken during the spacecraft’s fly-by of the ninth planet last year.

The new maps include global mosaics of Pluto and Charon, assembled from nearly all of the highest-resolution images obtained by New Horizons’ Long-Range Reconnaissance Imager (LORRI) and the Multispectral Visible Imaging Camera (MVIC). These mosaics are the most detailed and comprehensive global views yet of the Pluto and Charon surfaces using New Horizons data.

The new collection also includes topography maps of the hemispheres of Pluto and Charon visible to New Horizons during the spacecraft’s closest approach. The topography is derived from digital stereo-image mapping tools that measure the parallax – or the difference in the apparent relative positions – of features on the surface obtained at different viewing angles during the encounter. Scientists use these parallax displacements of high and low terrain to estimate landform heights.

You will also notice large areas of both Pluto and Charon that remain very fuzzy and unclear. What exactly is there will remain a mystery for many decades to come.

Dream Chaser test vehicle undergoing tow tests

8:58 pm

Capitalism in space: Sierra Nevada’s Dream Chaser engineering test vehicle underwent tow tests today.

Rolling on two main landing gear wheels and a nose skid, the Dream Chaser traveled down a runway Monday in Sierra Nevada’s latest tow test at Edwards Air Force Base, which is co-located with NASA’s Armstrong Flight Research Center. Once cut free from its tow vehicle, the Dream Chaser slowed to a stop, allowing engineers to gather data on the craft’s brakes, steering system, and guidance, navigation and control sensors that will line the spaceplane up for landing, according to Eric Cain, a Sierra Nevada engineer who described Monday’s test on the company’s Twitter account.

More tests are planned in the coming months, including additional tow tests and a “captive carry” flight with the Dream Chaser suspended under a helicopter.

This is the same engineering test vehicle that underwent tow tests and flew successfully once, though its landing gear failed up upon touchdown. They have replaced that landing gear, which was borrowed from the Air Force and was never intended to be the spacecraft’s wheels. Thus, they need to go through these tests all over.

Trump administration to increase use of asset forfeiture

2:44 pm

Theft by government: Attorney General Jeff Sessions today told a gathering of district attorneys that the Trump administration intends to increase the use of asset forfeiture, the procedure where the government steals private property merely because it suspects it might have been related to a criminal act, even if the owners are completely innocent.

Although the details have yet to be released, Sessions’ directive appears likely to loosen the restrictions on “adoptions” of forfeiture cases by the federal government—an alarming prospect for opponents of asset forfeiture. “Reversing the ban on adoptive seizures would revive one of the most notorious forms of forfeiture abuse,” Sheth said. “So-called ‘adoptive’ seizures allow state and local law enforcement to circumvent state-law limitations on civil forfeiture by seizing property and then transferring it to federal prosecutors for forfeiture under federal law. Bringing back adoptive seizures would create a road map to circumvent state-level forfeiture reforms.”

Sessions’ upcoming directive to increase asset forfeiture comes as little surprise. Sessions, a former prosecutor and U.S. senator, has been a stalwart defender of asset forfeiture throughout his career. He has already dismantled Obama-era directives on drug sentencing guidelines and ordered a review of all of the existing consent agreements between the Justice Department and police departments that were found to be violating residents’ constitutional rights.

This is only more evidence that both parties in Washington are corrupt power-grabbers who don’t give a damn about the Constitution and the real rule of law. Sessions might be good in some areas, but in others he is as bad as Eric Holder.

NASA communications satellite damaged during launch prep

8:20 am

A NASA TDRS communications satellite, scheduled for a August 3 launch on a ULA Atlas 5 rocket, was damaged on July 14 while it was undergoing final preparations for launch.

Though the issue apparently involves one of the satellite’s main antennas, it is unclear what happened exactly or how extensive the damage was. Furthermore, this article about the incident notes that an earlier incident had also occurred during shipping.

It is understood this latest incident is not related to a ‘close call’ that NASA was investigating earlier in the flow. That incident involved the spacecraft’s shipping container – containing environmental instrumentation – which slid a couple of feet on the trailer it was being winched on to.

If I was a customer who might want to buy the launch services of ULA, I would demand detailed information about why these incidents happened, including what measures are being taken to prevent them from occurring again.

White House appoints first member of National Space Council

11:03 am

The Trump administration today announced that Scott Pace will be the executive secretary of the National Space Council, headed by Vice-President Mike Pence.

Some might immediately think I will be upset by this choice, as Pace wrote a critical and what I consider to be a weak review of my policy paper, Capitalism in Space. This however is not true. We might have disagreed on some points, but I think that Pace might be an ideal choice. He has the ear and the support of the big government space companies, but also understands the need to let private enterprise run things more, a point he himself expressed in his review of my policy paper. As Dr. David Livingston of The Space Show wrote me today in an email,

Pace was the deputy administrator when Mike Griffin formed COTS which has turned out to be a pillar program for the emerging commercial space industry. I also know Scott is grounded well in economics, policy, and realism. He is politically savvy as well and that expertise will be needed to move policy and constructive programs forward.

Pace’s connections with the contractors who have been building SLS/Orion for decades are of course a concern, but his connections with COTS is cause for celebration. We can only wait and see where this goes.

House appropriations approves NASA and NOAA budgets

10:12 am

The squealing of pigs: The House appropriations committee yesterday approved the budgets for both NASA and NOAA, essentially accepting the budget numbers approved by its subcommittee.

Overall, the House increased spending over the Trump administration’s proposed cuts. Only in the area of climate did the legislators appear to support those cuts, and even here they pumped more money in.

The Trump Administration proposed a deep cut to [NOAA’s Polar Follow-On mission] saying it will re-plan the program ($180 million instead of the $586 million NOAA said last year it would need for FY2018). The committee went even further, approving only $50 million, but added it would reconsider if NOAA provides a better explanation of how it is restructuring the program. NOAA’s plans for new space weather satellites also fell far short of what the agency planned last year, although the committee provided more ($8.5 million) than the Trump Administration requested ($500,000).

In general, do not expect this Republican Congress to gain any control over the federal deficit. They are as spendthrift as Democrats. The only difference is their choice of programs.

Luxembourg parliament adopts draft space law

9:57 am

Capitalism in space: The Luxembourg parliament yesterday adopted a draft space law that will allow that country to authorize, under the Outer Space Treaty, future private enterprise missions in space, including mining on the Moon and the asteroids.

The press release makes the following claim:

The Grand Duchy is thus the first European country to offer a legal framework ensuring that private operators can be confident about their rights on resources they extract in space. The law will come into force on August 1, 2017. Its first article provides that space resources are capable of being owned. The country’s law also establishes the procedures for authorizing and supervising space exploration missions.

In reading the actual law [pdf], however, I do not think this really does what they claim. All the law does is simply state that “Space resources are capable of being appropriated.” That’s it. They are essentially saying that any private profit-oriented mission that launches under Luxembourg’s authorization will have their blessing to take as much from any planetary body as they desire. No property rights are delineated, including the borders of any territory owned, which is not surprising since the Outer Space Treaty forbids Luxembourg from doing so.

In fact, I think this illustrates for us all the future as we colonize the solar system, assuming the Outer Space Treaty is not revised or dumped. Like pirates, nations (or their citizens) will grab as much as they can, and will then use force to protect those holdings from any one else. Everyone will have to do this, because there will be no legal framework to establish their claims.

Since it appears, at least for the present, that no one wants to change the Outer Space Treaty, expect the future in space to be a brutal legal nightmare for all involved.
