Earth-sized exoplanet discovered orbiting dwarf star 55 light years away

10:49 am

Using a number of ground-based telescopes worldwide, astronomers have discovered an Earth-sized exoplanet orbiting what the scientists label an “ultra-cool” dwarf star only about 55 light years away.

You can read the paper here.

Though Earth-sized, this exoplanet is not habitable. It orbits the star every 17 hours and is believed to be tidally locked, with one side always facing the star. More important, though this red dwarf star has likely existed for many tens of billions of years and will continue for many tens of billions of years into the future, the star is too dim and lacking in the kind of resources needed for life. It also drenches the planet with bursts of radiation, which is also believed to have stripped the planet of an atmosphere.

Private satellite snaps picture of ISS in orbit

10:37 am

ISS as seen by HEO Robotics satellite
Click for original image.

One of the satellites in the commercial satellite constellation run by the Australian company HEO Robotics to monitor objects in space successfully took a picture of ISS this week as it zipped by only 43 miles away.

That picture is to the right, reduced to post here. The relative speeds between the satellite and ISS was about 3.7 miles a second. The station’s main truss, which holds up its solar panels and heat radiators, is the vertical structure going from upper left to lower right. The habitable modules cross this at right angles, with what appears to be the Russian section on the right with a Soyuz or Progress docked to the port at the end. A Dragon capsule can be seen at the opposite end, docked to the American section on the left.

The company’s satellites have previously provided imagery of other objects in orbit, including the ERS-2 satellite just before it was de-orbited as well as China’s Tiangong-3 space station during its assembly.

Potentially serious problem on BepiColombo Mercury mission

10:14 am

According to the European Space Agency (ESA), engineers have discovered what could be a potentially serious problem on BepiColombo mission that is presently on its way to Mercury.

The solar arrays and electric propulsion system on the Mercury Transfer Module are used to generate thrust during the spacecraft’s complex journey from Earth to Mercury.

However, on 26 April, as BepiColombo was scheduled to begin its next manoeuvre, the Transfer Module failed to deliver enough electrical power to the spacecraft’s thrusters.

A combined team from ESA and the mission’s industrial partners set to work the moment the issue was identified. By 7 May, they had restored BepiColombo’s thrust to approximately 90% of its previous level. However, the Transfer Module’s available power is still lower than it should be, and so full thrust cannot yet be restored.

The press release implies that this issue won’t prevent the spacecraft from entering orbit around Mercury as scheduled in December 2025, but one wonders how that could be if it doesn’t have sufficient power to do the proper course correction during its last major flyby of Mercury in September 2024. If it misses its precise route in ’24 it could miss Mercury entirely in ’25.

Engineers are analyzing the situation to see what can be done to get it to Mercury, while also trying to figure out what caused this power problem in the first place in order to fix it.

Congress passes new authorization bill for FAA that includes short extension of “learning period”

10:05 am

The new FAA authorization bill that that House approved yesterday and was passed previously by the Senate includes a short extension to the end of the year of the so-called “learning period” that is supposed to restrict the agency’s ability to regulate the new commercial space industry.

That limitation was first established in 2004 with a time period of eight years. It has been extended numerous times since then. The most recent extensions however have been very short, suggesting Congress (mostly from the Democrat side of the aile) wants to soon eliminate it. Whether that happens when it comes up for extension again at the end of 2024 will depend greatly on which party is in control after the election.

It really doesn’t matter. Everything the FAA has been doing in the past three years suggests this learning period no longer exists anyway. The agency has been demanding every new American company or rocket or spacecraft meet much higher regulatory requirements, which appears to have slowed significantly the development of those new companies, rockets, or spacecraft in the past two years.

Lithuania signs Artemis Accords

9:54 am

Lithuania yesterday became the 40th nation to sign the Artemis Accords, joining the American alliance for exploring the solar system.

The alliance now includes these nations: Angola, Argentina, Australia, Bahrain, Belgium, Brazil, Bulgaria, Canada, Columbia, Czech Republic, Ecuador, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovenia, South Korea, Spain, Sweden, Switzerland, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

The press release for this announcement differed slightly from the last few, all of which emphasized how the accords were designed to “reinforce” the Outer Space Treaty, the exact opposite of its original goals, which was to build an alliance of nations focused on getting around or eliminating the restrictions of the Outer Space Treaty on private property in space. Today the press release was more vague:

NASA, along with the Department of State and seven other nations, established the Artemis Accords in 2020 to lay out a set of principles grounded in the Outer Space Treaty of 1967 and three related space treaties. With the commitment of now 40 nations, the accords community will facilitate a long-term and peaceful presence of deep space exploration for the benefit of humanity.

Does this mean the Biden administration is going to return to the accords’ original goal? I doubt it. I think instead they decided they needed to be less obvious about their new intentions, which increasingly appears to be to use this alliance to foster globalist international cooperation aimed at keeping all power and legal control in the hands of the governments themselves.

Why are so many conservatives such downers?

4:07 pm

Frankly, for the Joe Biden campaign these numbers are an absolute disaster
“Frankly, for the Joe Biden campaign these numbers
are an absolute disaster.” Click for full video.

In the past two weeks I have noticed two political trends within the United States, one that seems quite hopeful and another that depresses me to the bottom of my soul.

The hopeful trend has to do with the left and what appears to be a growing collapse of its political support. The pro-Hamas riots on college campuses and elsewhere have not had the impact of the 2020 Antifa and BLM riots, where those disruptions struck fear into ordinary Americans while instilling them with a deep unfounded guilt that paralyzed them into either inaction or endorsing the foolish racist policies of that BLM movement.

In 2024 the pro-Hamas riots are doing the exact opposite. They are antagonizing everyone, and highlighting the racism and violence that is presently very inherent within the modern policies of the Democratic Party. Who wants to support a party whose base justifies and supports the work of terrorist organizations like Hamas, that torture, rape, and murder of innocents, including women, children, and babies?

On top of those ugly riots, Biden’s administration in almost all things has proven to be a disaster. Inflation has been terrible, the economy has doing poorly, the illegal immigration is out-of-control and impacting not just Republican border states but the Democratically-controlled inner ciites. Internationally Biden’s weak and indecisive leadership has led to wars in the Ukraine and Middle East, with tensions rising in many other places.

The result has been disastrous polls for Joe Biden — across the board — suggesting that not only will Donald Trump win the November election, he will do so with such strong numbers it will be impossible for even the worst vote tampering by the Democrats to overthrow that victory. Those polls also suggest that the Republicans will gain a large majority in the Senate, and likely a larger renewed majority in the House.

The disaster that is Joe Biden and the viciousness of the Democratic Party base has become so evident that even some previously knee-jerk Democrats are beginning to admit to it, and are attempting to change it. They don’t seem to be succeeding, but that effort illustrates further these hopeful trendlines. If even Democrats can no longer stand what their party stands for, then there is a good chance we might finally see that party clean up its act, or die and be replaced with something more laudable.

You must then wonder: What trend could possibly exist at this time that could be depressing me to the bottom of my soul?

Juno looks down at Jupiter

9:50 am

Jupiter as seen by Juno on May 12, 2024
Click for original image.

Cool image time! The picture to the right, rotated, reduced, and annotated to post here, was taken on May 12, 2024 by the camera on the Jupiter orbiter Juno during its most recent close-fly of the gas giant, its sixty-first since it arrived in 2016. The picture was snapped when Juno was about 34,674 miles away from Jupiter as it flew over the northern hemisphere.

Citizen scientist Thomas Thomopoulos then took that raw image and enhanced and enlarged it to bring out the storm details. You can see the distinct bands that cut across Jupiter’s equatorial and mid-latitudes. The reddish band is where the Great Red Spot is located, though that spot is not seen in this picture.

As we move north those bands slowly transition into the chaotic storms of the polar regions, which also circle the pole but do not form bands.

For scale I have added a circle that approximates the Earth’s size in comparison to Jupiter. You will notice that some of those polar storms are as big if not bigger than the Earth itself. To think we presently have any real understanding of the processes that create Jupiter’s climate and weather systems is to be arrogant beyond belief.

Fortunately, the scientists who study Jupiter are not that arrogant, though they often can’t admit it and are forced to sound otherwise when ignorant journalists and NASA managers demand more answers from them then are possible. The scientists understand that what makes pictures like this intriguing is not what it tells us but the amount of ignorance it reveals. To get funding for future research however sometimes requires they sound more knowledgeable than they are.

The aurora as seen looking down from space

9:12 am

The aurora over the U.S. on May 11, 2024
Click for original image.

NOAA on May 13, 2024 released a set of eight images taken by its fleet of JPSS weather satellites, showing the strong Aurora Borealis or Northern Lights that were activated over the May 11th weekend due to several very strong solar flares on the Sun and sent a geomagnetic storm at the Earth.

One of those images, reduced to post here, is to the right. You can see the eastern coast of the United States, outlined by city lights, with a band of aurora cutting across the northern half and reaching south below the Great Lakes. The other seven images are available at the link above.

The geomagnetic storm was the strongest produced by the Sun in more than two decades, since 2003. That storm occurred during solar maximum, as did the May 11th this past weekend. However, the Sun experienced another solar maximum in-between, in 2014, which produced few such storms, and none as strong.

I want to add that despite the screams of panic prior to the arrival of this storm, its arrival produced only minor disturbances in the world’s electrical grid, and in fact was proof positive that the many decades of work that electrical companies have devoted to protecting the grid from such storms has paid off. It is very unlikely any major storm from the Sun can harm that grid in the future, unless of course we get lazy and stop maintaining it.

FAA schedules first three public meetings for Starship/Superheavy impact statement review

8:48 am

The FAA has now scheduled the first three public meetings as part of its new environmental impact statement review of SpaceX’s proposed construction plans at Cape Canaveral.

The in-person open houses will feature information stations where the FAA will “provide information describing the purpose of the scoping meetings, project schedule, opportunities for public involvement, proposed action and alternatives summary, and environmental resource area summary. Fact sheets will be made available containing similar information,” the project website says.

“At any time during the meetings, the public will have the opportunity to provide verbal comments to a court reporter or written comments via a written comment form at one of several commenting stations,” the website says.

It appears that SpaceX is proposing two different options for establishing an additional launchpad for Superheavy/Starship. Its preferred option is to refurbish pad LC-37, which was most recenly used by ULA to launch its Delta-4 Heavy in April. A second option is to develop a new pad entirely, dubbed LC-50.

Though the FAA claims this new impact statement is necessary because SpaceX has upped the planned annual Superheavy/Starship launches from 24 to 44, that claim is bogus. The difference is not that significant, and more important, rockets have been launching from these pads now for almost three-quarters of a century, and the environment has not only not been harmed by that activity, the wildlife surrounding the cape has prospered tremendously by the creation of a large zone where no development can occur.

That history is the real impact statement, and it proves the new red tape is unecessary. What the FAA (and the Air Force) are now doing is simply lawfare against SpaceX.
