An ancient ocean on Ceres?

Two studies released today by the Dawn science team suggest that the spacecraft has found evidence that an ancient ocean once existed on Ceres.

In one study, the Dawn team found Ceres’ crust is a mixture of ice, salts and hydrated materials that were subjected to past and possibly recent geologic activity, and this crust represents most of that ancient ocean. The second study builds off the first and suggests there is a softer, easily deformable layer beneath Ceres’ rigid surface crust, which could be the signature of residual liquid left over from the ocean, too.

Trump Justice Department settles lawsuits over Obama IRS harassment

The Trump administration has come to a settlement with the lawsuits filed by tea party groups over their harassment by the IRS during the Obama administration.

The government apologized Thursday for illegally targeting tea party groups for intrusive scrutiny and agreed to settlements with hundreds of organizations snared in the targeting, bringing to a close one of the more embarrassing episodes of the Obama administration.

Attorney General Jeff Sessions said the IRS owed the groups an apology after years of poor treatment and even longer refusal to concede bad behavior. He placed blame on “the last administration,” saying the targeting that went on under President Obama “was wrong and should never have occurred.”

One of the settlement agreements, filed in federal court in Washington, D.C., officially admits that the IRS singled out groups because of their political beliefs, in defiance of the law. The other settlement, in a class-action lawsuit in Ohio, includes a “generous” payout to more than 400 groups snared, according to a lawyer involved.

The amount of the settlement was not released.

Meanwhile, John Koskinen remains head of the IRS, despite a long documented record of stone-walling and obstruction of justice. If the Trump administration is really sincere about fixing this proglem so that it won’t happen again, why has Trump not fired him?

Scientists propose adding smog to atmosphere to fight global warming

What could possibly go wrong? Global warming scientists have proposed injecting sulphate aerosols (another name for pollution) into the upper atmosphere in order to counter their predicted global temperature rise.

Experts are considering ploughing sulphate aerosols into the upper atmosphere which would cause some of the suns rays to be reflected back out into space. This could potentially cool the Earth down and help counter the effects of climate change, scientists say.

The move would also help reduce coral bleaching and help calm powerful storms.

James Crabbe, from the University of Bedfordshire, is leading the study and his initial results suggest the plan could help cool the planet.

This proposal is based on such flimsy science it appalls me that any scientist would even consider it, especially when you think about the unknown consequences.

Rosetta’s capture of a dust jet from Comet 67P/C-G

Dust jet on Comet 67P/C-G

Cool image time! The Rosetta science team has released images and data gathered in July 2016 when the spacecraft successfully observed a dust outburst erupting from Comet 67P/C-G’s surface. The image on the right, slightly reduced in resolution, shows that outburst.

When the Sun rose over the Imhotep region of Rosetta’s comet on July 3, 2016, everything was just right: As the surface warmed and began to emit dust into space, Rosetta’s trajectory led the probe right through the cloud. At the same time, the view of the scientific camera system OSIRIS coincidentally focused precisely on the surface region of the comet from which the fountain originated. A total of five instruments on board the probe were able to document the outburst in the following hours.

As should be expected, the results did not match the models or predictions. The jet, instigated by water-ice just below the surface turning into gas when heated by the Sun, was much dustier than predicted. They have theories as to why, but it appears that no one likes these theories that much.

More hints that the first SLS launch will be delayed again

Government in action! The head of the Marshall Space Flight Center yesterday once again hinted that the first unmanned launch of SLS/Orion, presently scheduled for late in 2019, could be delayed again.

In September, the agency said in a statement that it would announce a new target date for EM-1 in October, citing the need to account for a range of issues, including progress on the European-built Orion service module and shutdowns at NASA centers from hurricanes in August and September.

However, an update in October is increasingly unlikely. “Within a few weeks, I think [NASA Acting Administrator Robert Lightfoot] intends to codify whatever that date is going to be,” Todd May, director of NASA’s Marshall Space Flight Center, said in remarks at the American Astronautical Society’s Wernher von Braun Memorial Symposium here Oct. 25.

Bill Hill, deputy associate administrator for exploration systems development at NASA, offered a similar assessment. “Probably in the next month, maybe sooner,” he said in an interview.

These hints have been standard operating procedure for announcing SLS’s endless delays for the past decade. First they make hints that a delay might happen, but reassure everyone that it is very unlikely. Then they follow this up later with announcements about how they need more time to accomplish all their goals. By the third announcement they outline a possible new schedule, including some delay but insist that it isn’t likely. Finally, they release the new dates, often as an aside during some other announcement in order to minimize the news.

It should be noted that the new dates have almost never been realistic. NASA has usually known that the new dates are interim, and that further delays will likely require more of this same dance to make them public.

So, here is my prediction: They are preparing us for the fact that the first unmanned flight will likely slip into 2020, which means the first manned flight slips for certain into 2023, as I have been predicting for the past three years.

Saudi Arabia to invest $1 billion in Virgin Galactic and Virgin Orbit

Capitalism in space: Saudi Arabia and Virgin have signed a non-binding agreement for Saudi Arabia to invest $1 billion in Virgin Galactic and Virgin Orbit.

I’m not sure what to make of this press release. The agreement is clearly called “non-binding,” which means Saudi Arabia is not obliged to provide any funds. At the same time, the deal appears to shift power and control of the two Virgin companies to the Arab country, which if successful (a big “if”) would also quickly give Saudi Arabia both a manned and smallsat launching capability.

Why they chose Virgin appears at first baffling, considering that company’s repeated inability to achieve any of its promises. It could be, however, that Richard Branson’s funds are drying up, and that he needed this deal to keep both companies afloat. Saudi Arabia thus saw an opportunity and grabbed it.

Boeing’s Starliner undergoing drop tests

Capitalism in space: Boeing’s Starliner manned capsule yesterday successfully completed the 11th of 14 drop tests in preparation for launch.

The article includes extensive comments by two NASA astronauts who are working with Boeing on these drop tests. I found this quote interesting:

[Sunita] Williams and [Eric] Boe said there are benefits and drawbacks to either type of landing, but they preferred land over water. Williams speaks from experience: She has already made a land landing aboard a Russian Soyuz capsule. “When you land on land, maybe it’s a little bit harder,” Williams said. “But when you’re coming down at high speed, the water’s hard, too.

“Landing on water, if somebody’s right there to rescue you and they know exactly where you’re coming down, that works. And we’ve shown that works with the Apollo program. But, landing on water — I’m a Navy guy, there’s a big ocean out there and it’s a little space capsule and there’s some definite risks to that, too.

“Landing on the Soyuz, you open the hatch, you smell the grass, you’re not in a huge rush to get out or stay in. You know you’re in a solid place and you know you can take your time getting out and the rescue forces will be there eventually, if they’re not there knocking on the door.”

The article also noted that Boeing plans to refurbish each capsule and reuse it up to ten times.

Update on five Iranian satellite projects

During a recent press conference the head of the Iranian Space Agency has provided an update on the status of five long-delayed Iranian satellites.

Only one of the satellites appears ready for launch, and is awaiting a rocket to put it in orbit. The satellites are either designed to do remote sensing of the Earth or communications, with some having unstated military applications.

Email proves Obama administration targeted opponents for harassment by the IRS

Working for the Democratic Party: An email from an IRS agent, recently uncovered by lawyers representing tea party groups in a class action lawsuit, clearly shows that the Obama administration targeted for harassment conservative groups, based solely on their party affiliation.

[T]he April 1, 2011, email from Elizabeth C. Kastenberg, an official in the agency’s exempt organizations division, says it was explicitly the organizations’ politics that landed them on the target list. “These cases are held back primarily because of their political party affiliation rather than specifically any political activities,” Ms. Kastenberg wrote in an alert to other IRS employees, including her supervisor.

Edward Greim, the attorney for NorCal Tea Party Patriots and hundreds of other groups that are part of the class-action lawsuit, said that was a major admission. “What Kastenberg was saying was they have all different activities, and so there’s no ‘political activities’ that cut across this group. Instead, it’s really their political party affiliation they have in common,” he said. [emphasis mine]

In other words, the IRS decided to demand inappropriate information from these Republican organizations, merely because they were Republican, contradicting utterly the claim by the agency that they were only checking to make sure that these groups, based on their activities, should get non-profit status.

FBI informant cleared to testify on Clinton Uranium Russian deal

The Trump Justice Department has cleared the FBI informant with direct knowledge of the Clinton-Russian uranium bribery scandal.

The informant worked undercover to investigate bribery and intrigue in the Russian nuclear industry during the Obama administration and was, until Wednesday, bound by a gag order from speaking about what he knew. According to sources at the Department of Justice, the informant is now cleared to testify about a wide range of issues including, specifically, the Clinton Foundation. The informant worked undercover to investigate bribery and intrigue in the Russian nuclear industry during the Obama administration and was, until Wednesday, bound by a gag order from speaking about what he knew.

According to sources at the Department of Justice, the informant is now cleared to testify about a wide range of issues including, specifically, the Clinton Foundation. In a statement, DOJ spokesman Ian Prior told media outlets: “As of tonight, the Department of Justice has authorized the informant to disclose to the Chairmen and Ranking Members of the Senate Committee on the Judiciary, the House Committee on Oversight and Government Reform, and the House Permanent Select Committee on Intelligence, as well as one member of each of their staffs, any information or documents he has concerning alleged corruption or bribery involving transactions in the uranium market, including but not limited to anything related to Vadim Mikerin, Rosatom, Tenex, Uranium One, or the Clinton Foundation.”

The article says the informant will testify Wednesday night before Congress, but also notes that it is unclear as yet how or where that testimony will be given. More details about the scandal here.

If this person reveals as much as the news stories have suggested, it could very well finally shatter the protection the press and the left have given the Clinton since Bill Clinton’s problems as president in the 1990s. What I am sensing is that the Democratic Party might possibly be considering throwing the Clintons to the wolves in an effort to keep the wolves off of it.

Then again, I tend to be a wide-eyed optimist.

The first large object identified coming from interstellar space

Astronomers think they have spotted the first large object to come from beyond the solar system.

Based on its apparent brightness, dynamicist Bill Gray calculates that it would have a diameter of about 160 meters (525 feet) if it were a rock with a surface reflectivity of 10%. “It went past the Sun really fast,” Gray notes, “and may not have had time to heat up enough to break apart.”

Now it’s headed out of the solar system, never to return. It passed closest to Earth on October 14th at a distance of about 24,000,000 km (15,000,000 miles), and astronomers worldwide have been tracking it in the hopes of divining its true nature — especially whether it’s displaying any cometary activity.

…According to Gray, Comet PanSTARRS appears to have entered the solar system from the direction of the constellation Lyra, within a couple of degrees of right ascension 18h 50m, declination +35° 13′. That’s tantalizingly close to Vega — and eerily reminiscent of the plot of the movie Contact — but its exact path doesn’t (yet) appear to link any particular star.

This object entered the solar system moving at 26 km (16 miles) per second. At that speed, in 10 million years it would traverse 8,200,000,000,000,000 km — more than 850 light-years.

Reminds me of a really good science fiction novel I read recently. They should keep an eye on it for as long as they can, just in case it suddenly changes course and settles into a more circular orbit around the Sun. In the unlikely case it does that, it might just be the biggest discovery in history.

Freon leak on U.S. part of ISS?

A news report today says that an accident in the U.S. portion of ISS caused a freon leak.

The report also said there was a leak of ammonia, and that he crew is not in danger from either leak.

The report is also very vague and sparse with information, and appears to come from the Russians, since it also says that the leaks suggest “systemic problems in the operation of the station’s U.S. segment.”
