New images from Mangalyaan

10:18 am

Arsia Mons

Indian scientists have released a new set of color images taken by their Mars orbiter, Mangalyaan.

The image on the right is of Arsia Mons, one of the three giant volcanoes to the east of Mars’ biggest volcano, Olympus Mons. Arsia Mons is important for future manned colonization, as there are known caves on its western flanks. In addition, those western flanks show solid evidence of past glaciers, which means that it is very likely that those caves will harbor significant quantities of water-ice, making settlement much easier.

NASA schedules commercial manned demo missions to ISS

6:45 pm

The competition heats up: NASA has now added to its ISS schedule the planned launch dates for the first demo missions of SpaceX’s and Boeing’s privately built manned capsules.

For Boeing, its CST-100 will first launch on an uncrewed test flight to the Station via the “Boe-OFT” mission in Apr, 2017 – on a 30 days mission, ending with a parachute assisted return. Should all go to place, the second mission will involve a crew – yet to be selected – on a mission designated “Boe-CFT”, launching in July, 2017, on a 14 day mission to the ISS.

The [planning] dates show SpaceX to be the most advanced in the Commercial Crew path, with their projected test flight dates currently set to win the honor of being the first Commercial Crew vehicle to arrive at the orbital outpost. That first Dragon 2 mission, designated “SpX-DM1″, has a December, 2016 launch date, ahead of a 30 day mission – most of which will be docked to the ISS – ending with a parachute assisted landing in the Pacific ocean. This would be followed by “SpX-DM2″, a crewed flight, launching in April of 2017, on a 14 day mission. This would mark the first time astronauts have launched from American soil on a US built spacecraft since Atlantis’ STS-135 mission in 2011.

American manned space exploration should begin to get very exciting in the next two years, with multiple companies now capable of putting humans in space.

The oceans that Mars lost

12:47 pm

The lost oceans of Mars

New data from a six year study of the water in the modern Martian atmosphere have allowed scientists to estimate the amount of water Mars once had.

About four billion years ago, the young planet would have had enough water to cover its entire surface in a liquid layer about 140 metres deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres. “Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space,” said Geronimo Villanueva, a scientist working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, USA, and lead author of the new paper.

The image on the right is an artist’s conception of the oceans that would have existed on Mars, based on modern elevation data.

I must note that this conclusion, the size of the lost Martian ocean, is based on the assumption that the isotope ratios of Martian water started out the same as the Earth’s. While this is a reasonable assumption, it does not have to be true. Nonetheless, these conclusions, using ground-based telescopes, do match up with similar data obtained by Curiosity.

Lerner illegally provided Democrats with confidential tax information

9:21 am

Working for the Democratic Party: Newly released emails now prove that Lois Lerner not only illegally provided confidential tax information to Congressman Elijah Cummings (D-Maryland), her harassment of conservatives was apparently coordinated with the Congressman’s office.

In addition, Cummings had denied these facts publicly and privately to the House as he tried to shut its investigation down prematurely.

“These documents, indicating involvement of IRS officials at the center of the targeting scandal responding to your requests, raise serious questions about your actions and motivations for trying to bring this investigation to a premature end. If the Committee, as you publicly suggested in June 2013,’wrap[ped] this case up and moved on’ at that time, the Committee may have never seen documents raising questions about your possible coordination with the IRS in communications that excluded the Committee Majority,” [states] the letter sent by [Chairman of the House Oversight Committee Darrell Issa and the chairmen of five congressional subcommittee chairmen].

“As the Committee continues to investigate the IRS’s wrongdoing and to gather all relevant testimonial and documentary evidence, the American people deserve to know the full truth. They deserve to know why the Ranking Member and Minority staff of the House Committee on Oversight and Government Reform surreptitiously contacted the IRS about an individual organization without informing the Majority Staff and even failed to disclose the contact after it became an issue during a subcommittee proceeding…We ask that you explain the full extent of you and your staff’s communications with the IRS and why you chose to keep communications with the IRS from Majority Members and staff even after it became a subject of controversy.”

It must be made clear here what happened: Cummings’ office contacted Lerner at the IRS about a specific conservative organization, demanding confidential tax information about it and that it be targeted for investigation by the IRS. Lois Lerner immediately complied. And his office did it not because of any illegal act by this conservative organization but because that organization was successfully uncovering voter fraud that helped Democrats get elected.

How does this make you feel? Criticize a Congressman and he has the power to send the IRS after you.

NASA picks landing site for next Mars lander

8:51 am

NASA scientists have chosen a specific region of Mars, Elysium Planitia, to land its next Mars science probe.

The landing-site selection process evaluated four candidate locations selected in 2014. The quartet is within the flat-lying “Elysium Planitia,” less than five degrees north of the equator, and all four appear safe for InSight’s landing. The single site will continue to be analyzed in coming months for final selection later this year. If unexpected problems with this site are found, one of the others would be imaged and could be selected. The favored site is centered at about four degrees north latitude and 136 degrees east longitude.

InSight launches next year.

Most Republicans fold to Boehner

11:00 am

It appears there will not be a battle in the Republican Party to replace John Boehner.

Instead, the Republicans in the House appear eager to accept their place as brown-nosing boot-lickers to Nancy Pelosi and Barack Obama. Moreover, the leadership that likes licking these boots is getting aggressive about it:

Heightening the party’s intramural angst were new political ads by the American Action Network, run by Boehner’s allies. They began running Tuesday in the districts of about 50 House Republicans who defied him on Homeland Security last week. The $400,000 campaign includes phone calls, a few TV ads, and ads on popular conservative talk radio shows. They urged constituents to call their representatives, not vote them out of office.

For years I’ve argued against splitting off a third party, because I know it will only fracture the right’s strengths and give more power to the left. At this point, however, I see no point supporting this Republican Party. It appears they have no interest in fighting for conservative values, and merely wish to act as a go-between between the left and the right, with their sole goal being to placate the right as they facilitate left wing policies.

If we are to be led by leftists, let’s let them lead, do their worst, and show the world exactly who they are. At least then there will be no doubt to future generations who destroyed this country.

Obama threatens veto of House bill to limit EPA use of unpublished data

9:57 am

Here we go again: The House is about to vote on a Republican bill to require EPA to use only publicly available data.

The bills, introduced by a mostly Republican cast of sponsors in both the House and the Senate, would require that EPA use only publicly available, reproducible data in writing regulations and seek to remake the membership and procedures of the agency’s science advisory panels. Supporters, including industry groups such as the U.S. Chamber of Commerce, argue that the legislation would improve the transparency and soundness of how EPA uses science, making regulations less costly and more effective.

Opponents, however, are calling the bills wolves in sheep’s clothing. “I cannot support legislation that makes it easier for industry to implement their destructive playbook, because risking the health of the American people is not a game that I’m willing to play,” said Representative Paul Tonko (D–NY) at a 25 February committee meeting on the bills.

The White House has issued statements saying Obama will veto the bill. How hard to do you think John Boehner and Mitch McConnell will fight for this legislation?

India announces scheduled to test a prototype space plane

9:48 am

The competition heats up: India’s space agency ISRO has announced that they will test fly a prototype space plane sometime between April and June this year.

The test and prototype both sound very similar to Europe’s IXV prototype space plane, test flown only a few weeks ago.

“Technology Demonstrator winged body vehicle weighing 1.5T will be lofted to a height of 70 km using solid booster, thus attaining five times the speed of sound. Thereafter, it will descend by gliding and splashing down into the sea”, said an official statement. This test flight would demonstrate the Hypersonic aerodynamics characteristics, Avionics system, Thermal protection system, Control system and Mission management.

Both programs also remind me of many similar NASA engineering test programs, most of which ended up as dead ends, with the new technology never applied to actual real world missions. Whether that happens in Europe and India remains the main question. The increasing competition in space should help prevent it, but these are also government-run programs, so their goal has less to do with profit and competition than pork and political maneuvering.

NASA considering ion engines for next Mars orbiter

9:40 am

Rather than using conventional chemical thrusters for a Mars orbiter planned for the 2020s, NASA managers are considering using ion engines instead.

Worried its fleet of Mars orbiter is aging, NASA intends to dispatch the spacecraft to the red planet in September 2022 to link ground controllers with rovers and extend mapping capabilities expected to be lost when the Mars Reconnaissance Orbiter stops functioning.

Engineers also want to add ion engines to the orbiter and fly the efficient electrically-powered thruster system to Mars for the first time, testing out a solar-electric propulsion package that officials say will be needed when astronauts visit the red planet. Ion engines produce just a whisper of thrust, using electric power to ionize atoms of a neutral gas and spit out the particles at high speed. While the drive given by the thrusters is barely noticeable in one instant, they can operate for months or years, burning scant fuel compared to traditional chemical rockets.

That this decision requires long-winded and extended high level negotiations at NASA illustrates the slow and lumbering nature of government. Private enterprise is embracing ion engines now, and NASA itself is seeing its own spectacular ion engine success with Dawn. The decision should be a no-brainer, especially because the benefits of ion engines (low weight, more power, greater flexibility) are so obvious.

The race to map the space around the supermassive black hole at the center of our galaxy

9:30 am

The uncertainty of science: Using a new generation of telescopes, in space and on the ground, astronomers hope to better confine Einstein’s General Theory of Relativity by studying the distortion in light and energy produced by the powerful gravitational field surrounding Sagittarius A* (pronounced A-star), the 4 million solar mass black hole at the center of the Milky Way.

This is an excellent article explaining both the limits of our ability to study black holes as well as what we do know about Sagittarius A*.

Correction: Thanks to commenter Mike Nelson for noticing that I had mistakenly written “billion” instead of “million” for the mass of Sagittarius A* above.

Britain narrows its competition for spaceport

9:17 am

The competition heats up: The British government has down-selected its choices for a future spaceport in Great Britain to six airports, two of which have already said they are not interested in taking on the job.

The remaining four sites include two in Scotland, and one each in Wales and southwestern England. If I had to choose just based on orbital mechanics, the English site would win, as it is farther south thereby capable of putting more payload in orbit for the same fuel. However, politics and pork will certainly be a factor in any final decision, as this spaceport location is being decided not by private companies but by the British government.

Curiosity in trouble?

9:05 am

The Mars rover Curiosity has temporarily ceased work as engineers investigate what appears to be a short circuit in its electrical system.

The space agency said Tuesday that the electrical problem was discovered over the weekend as Curiosity tried to transfer bits of powder from a rock that it had drilled into. The short circuit stopped the rover’s robotic arm. Engineers are diagnosing the issue, and the testing is expected to take several days.

The worrisome components of this story are the words “short circuit” and “drill”, because of a known design flaw in the electrical system of the rover’s drill. It could very well be that this flaw, which could cause a short that could bring down the rover, is the cause of this electrical problem.

Boehner had made a deal with Pelosi

5:45 pm

Despite claiming that there had been no deal, John Boehner had negotiated a deal with the Democratic Party leadership to get a funding bill passed that also funded Obama’s illegal amnesty.

If there isn’t a successful revolt in the Republican Party to get Boehner replaced as Speaker, than that party will fall apart, giving more even power to the Democrats. It is unacceptable for a Republican leader to back stab his own caucus like this, and for them to accept it is as unacceptable.

Meanwhile, here are the names of the 75 House Republicans who backed the Democrats and Boehner in this back stab. I think I’d rather have Marxist Democrats in these seats than two-faced RINOs who say one thing during campaigns and then do another once elected. At least with the Marxist Democrats we’d know what we’ve got, and we can blame them when things go wrong. These Republican liars however have instead created the illusion that the left wing agenda of Obama and the Democrats is a bi-partisan effort.

Dawn bears down on Ceres

5:35 pm

Ceres' cratered surface

More cool images! As Dawn moves in on Ceres and prepares to enter orbit on March 6, it has managed to assemble enough images to produce a global map of the almost spheroid-shaped giant asteroid.

The bright spots however remain a mystery which cannot be answered until we get higher resolution images from much closer. Hopefully, Dawn will be able to do this once it is in orbit.

A list of politicians boycotting Netanyahu

9:00 am

Link here. The list is incomplete, as it doesn’t include Elizabeth Warren (D-Massachusetts). Nonetheless, it is instructive to note which party every single one of these politicians belongs to. I think you can guess.

But they support Israel! They said so!

In related news, it is now reported that President Obama has cut off providing Israel its intelligence information about Iran’s nuclear program.

But Obama supports Israel! He said so!

Boehner joins Democrats to support funding of Obama amnesty

8:58 am

Working for the Democratic Party: The Republican Speaker of the House John Boehner announced today that he has joined with the Democrats and will allow a vote on a funding bill for the Department of Homeland Security that also funds Obama’s illegal amnesty plan for illegal immigrants.

This flip-flop comes after months of Boehner saying he wouldn’t do this. “The House has acted. We’ve done our job. Senate Democrats are the ones putting us in this precarious position,” Boehner said on Fox News Sunday recently.

It’s unclear whether the vote will pass later on Tuesday, but if it does there are likely to be serious consequences against Boehner for having now flip-flopped into supporting Obama’s executive amnesty.

After this back-stab, I would not be shocked if the Republican caucus tears itself in two as its conservative half tries to get Boehner fired.

Update: The funding bill has passed, with almost 70% of House Republicans voting against it. With numbers like that, it is likely that John Boehner’s days as speaker are numbered. A majority of his own caucus is no longer willing to back him.

Yutu lives!

8:33 am

Despite an engineering failure that has prevented it from roving after only a few days on the Moon, the Chinese lunar rover Yutu continues to reawaken after each long lunar night, surviving now far longer than its planned three month lifespan.

Since the rover arrived in late 2013, it has now functioned in the hostile lunar environment for more than a year. This, along with other successful long missions, suggests that Chinese space engineering has matured to a point that it has the ability to achieve some significant long term goals.

Warren to boycott Netanyahu speech

11:25 pm

The modern Democrat: Senator Elizabeth Warren (D-Massachusetts) announced today that she will boycott Benjamin Netanyahu’s speech to Congress on Tuesday.

Warren voted against the Senate’s new Iran sanctions bill in the Senate Banking Committee in January, one of just four Democrats to oppose legislation that would impose new penalties on Iran in the event it reneges on any nuclear agreement with the United States.

Warren joins a handful of Senate Democratic Caucus members to skip the address, such as Al Franken of Minnesota and Bernie Sanders of Vermont, as well as dozens of House Democrats. Many are skipping because it’s election season in Israel and due to Boehner arranging the speech without consultation with the President Barack Obama, they say.

I single out Warren because she has been touted by many Democrats as their best candidate for President after Hillary Clinton. Yet, she is going to boycott hearing a speech from the only elected leader in the Middle East who happens to be our only reliable ally there. What could he possibly say that she might not like? Might he say that the policy of her Democratic president is dangerous and is allowing Iran, a country that has called for the genocidal destruction of both Israel and the United States, to build its own nuclear bombs? Could it be that she supports Obama’s policy? Her vote on the Iranian sanctions certainly suggests this.

I can tell you that the Democratic argument that John Boehner broke protocol in arranging the speech is petty fiddle-faddle. Considering the threat that Iran poses for the world, and the fact that Israel is our strongest ally to counter that threat, to not attend Netanyahu’s speech for these childish reasons is downright disgraceful. Yet, too many Democrats seem eager to show their hostility to Israel’s leader, while holding out the hand of conciliation to Iran.

Of course, when it comes election time she knows she has nothing to worry about. She knows that American Jews will continue to vote blindly for her and the Democrats.

Roy Clark & Buck Trent – Dueling Banjos

6:03 pm

An evening pause: While the version of this song for the movie Deliverance (1972) was quite good, I really dislike how that film made all country folk look like they were mentally and physically crippled. The portrayal seemed quite bigoted.

This performance, however, just shows us some great banjo playing, the way it should be done.

Obamacare causes insurance company to lose money

10:10 am

Finding out what’s in it: For the first time in 15 years, Blue Cross/Blue Shield of North Carolina will lose money in 2015 due to Obamacare.

Blue Cross and Blue Shield, the state’s largest health insurer, said Friday that it posted its first financial loss in 15 years as a result of insuring high numbers of older and sicker people under the Patient Protection and Affordable Care Act. The Chapel Hill organization signed up 257,704 people under the federal health care law, which requires insurers to provide coverage regardless of a customer’s health condition. New enrollees last year swelled Blue Cross’s covered membership to 3.91 million people, and boosted revenue by 25 percent to an all-time high of $8 billion.

But steep medical claims – for hip and knee replacements, heart procedures, specialty drugs and other costs – drove up medical claims from $5 billion in 2013 to $6.4 billion in 2014. Blue Cross also paid $156 million in ACA-related fees, a new cost for the company.

Federal subsidies under Obamacare are supposed to cover these loses, but then we must ask where is the bankrupt federal government going to get this money? In the end, someone is going to go bankrupt and we will all be worse off.

SpaceX has another successful commercial launch

9:26 am

The competition heats up: SpaceX’s Falcon 9 rocket successfully launched its first two-satellite payload to geosynchronouse orbit on Sunday.

The satellites were unusual in that they both have replaced all their chemical engines with ion engines, thus saving weight and cost.

While the satellites will need six to seven times longer to reach the desired orbit, the cost savings is enormous. “The advantage of that, of course, is you don’t carry liquid chemical fuel, which is very heavy,” Betaharon said. “This particular satellite, each of them weigh around 2,000 kilograms. Typically, if you get a satellite like that from other manufacturers, or even from Boeing using chemical propulsion, they would weigh something around 3,500 to 4,000 kilograms, or in some cases maybe more. That’s why, because it’s lower mass, we managed to put two of them on one rocket, which right away reduces your launch costs in half.”

When ABS and Eutelsat signed up for Falcon 9 launch services several years ago, the rocket cost about $60 million. “We paid under $30 million for each satellite, which is almost unheard of,” Betaharon said.

More information about the new satellite designs can be found here.

Nonetheless, the combined weight of the two satellites plus the need to get them to geosynchronous orbit forced SpaceX to forgo another attempt to land its first stage vertical. The rocket needed the fuel to get the satellites where they had to go.
