Comparing the weather on Mars and Earth
Heh: It is currently warmer in Gale Crater on Mars than in many parts of the United States.
Obviously those SUVs on Mars are causing the warming there. Obviously.

New York Times explains why it won’t publish Charlie Hebdo cartoons
Note that the Times has had no reluctance to show images that are as equally offensive to its Christian and Jewish readers. I wonder why the Muslims get this special treatment?
Meanwhile, representatives of the religion of peace have now taken hostages, both in a factory near Charles De Gaulle Airport as well as in a kosher grocery store in Paris.
Update: It appears both hostage situations have ended.
An update on the on-going ebola outbreak in Africa
The Centers for Disease Control today released graphs detailing the on-going ebola epidemic in West Africa.
What is significant about all the graphs at the link is that there is no sign of a let up or an easing of the epidemic. The numbers are still rising, even if the increase has slowed somewhat.
9 of the 10 worst countries for Christian persecution are Islamic
The religion of peace: A new assessment of Christian persecution worldwide has found that of the top ten most religiously oppressive nations nine are Islamic.
North Korea tops the list, but the rest are all countries where the majority of the population is Muslim. The report also found that “Islamic extremism is the main source of persecution in 40 of the 50 countries on the 2015 World Watch List.”
I wonder what these facts tell us? Anyone care to venture a guess? Maybe we should condemn Israel for this oppression? Yeah, that makes sense!
Ancient fossils on Mars?
A close look at features on the Martian surface seen by Curiosity suggests to one scientist the presence of ancient fossils of carpet-like microbiology.
On Earth, carpet-like colonies of microbes trap and rearrange sediments in shallow bodies of water such as lakes and costal areas, forming distinctive features that fossilize over time. These structures, known as microbially-induced sedimentary structures (or MISS), are found in shallow water settings all over the world and in ancient rocks spanning Earth’s history.
Nora Noffke, a geobiologist at Old Dominion University in Virginia, has spent the past 20 years studying these microbial structures. Last year, she reported the discovery of MISS that are 3.48 billion years old in the Western Australia’s Dresser Formation, making them potentially the oldest signs of life on Earth.
In a paper published online last month in the journal Astrobiology (the print version comes out this week), Noffke details the striking morphological similarities between Martian sedimentary structures in the Gillespie Lake outcrop (which is at most 3.7 billion years old) and microbial structures on Earth.
Noffke is very careful in her analysis. She doesn’t claim any proofs, only that her expert eye sees the same things on both planets. Most intriguing.
Falcon 9 launch rescheduled for Saturday
SpaceX and NASA have now rescheduled the Falcon 9/Dragon launch to ISS for Saturday morning at 4:47 am Eastern.
I am wondering if lack of light is going to effect the effort to vertically land the first stage.
Islam murders 12 people at magazine
The religion of peace strikes again: Twelve people were murdered today by Islamic terrorists at a French satirical magazine.
The magazine, Charlie Hebdo, had published many cartoons making fun of religion. Fortunately, they were able to avoid the hoards of Jewish and Christian terrorists that tried to kill them.
In addition, a car bomb has exploded in front of a synagogue in the suburbs of Paris. Update: An accident unrelated to terrorism.
The Obama administration has been quick to act, condemning the attacks while once again insisting that Islam is “a peaceful religion.” That is a quote, today, by Obama’s own press secretary.
Make sure you read James Delingpole’s prediction of what will happen next as our leaders will do anything to avoid facing reality so they can continue to live in a fantasy world where Islam is our friend and it is the evil racism of the west that caused this tragedy.
In defiance of Islam’s effort to impose its will on us all, here is a link to some of the cartoons Charlie Hebdo previously published making fun of Islam. Click on it. Spread it around. Let’s have everyone see it!
Comet impact theory replaced by common house fires
The uncertainty of science: Fused droplets found in many places across the globe and theorized to have come from a comet major impact that caused a major climate change around 13,000 years ago have now been found to have instead come from common house fires.
Since the 1970s when the Walter Alvarez found evidence of an asteroid impact in the Yucatan that could have caused the dinosaur extinction 65 million years ago, planetary scientists have seen asteroid or comet impacts everywhere. After all, impacts are cool disasters that play well to television producers and funding agencies.
Read this story however. It describes some very solid scientific work that wipes out one one of those cool theories, replacing it with something quite mundane.
New Hubble images to celebrate its upcoming 25th anniversary
The Space Telescope Science Institute (STScI) that operates the Hubble Space Telescope yesterday released two spectacular new images at the January meeting of the American Astronomical Society.
They also announced new data from Hubble that suggests a major eruption had occurred at the center of the Milky Way about two million years ago.
More Earthlike exoplanets confirmed
Worlds without end: Astronomers have confirmed from Kepler data the existence of 8 new exoplanets, all capable of having liquid water on their surface, with two more like Earth than any previous discovery.
These findings nearly double the number of known planets in the habitable zone, but researchers are especially excited about two of the new exoplanets: Their size, location, and star type means they could be rocky planets like Earth — which means they could have evolved life as we recognize it.
One of the planets, Kepler-438b, is only 12 percent bigger than Earth in diameter. That means it’s quite likely a rocky planet. Scientists have given it a 70 percent chance. Kepler-442b is a bit bigger at around 33 percent larger than Earth, but still has a 60 percent chance of being rocky.
But while 438b hits the sweet spot in size, 442b has it beat when it comes to distance from the sun. Both planets orbit a small red dwarf star, cooler than Earth’s Sun, but they also orbit more closely. 438b gets 40 percent more light than Earth, which means it has around a 70 percent chance of being able to hold liquid water. But with 66 percent as much light as our own planet, 442b has a 97 percent chance of being in the habitable zone.
Sierra Nevada loses its protest of NASA contract decision
The GAO has ruled against Sierra Nevada’s protest of NASA’s decision to pick Boeing for its manned spacecraft decision.
The ruling is not really a surprise. Even if political considerations gave Boeing an unfair advantage, the space agency has enough legal leeway to make this decision as it did. The GAO recognized that it would be inappropriate to overrule them.
Falcon 9 launch scrubbed
Due to issues in the rocket’s steering system this morning’s Falcon 9/Dragon launch was scrubbed.
They will try again Friday morning at 5:09 am Eastern.
The search for Philae goes on
Analysis of new data from Rosetta has still failed to locate Philae, though engineers are confident that sometime in May/June the sun will begin to charge its batteries so it turn back on and tell us where it is.
Chinese service module journeys to and from Moon
The competition heats up: The service module of China’s first lunar return capsule, launched and successfully returned to Earth in November, is returning to lunar orbit after journeying to L2 more than 35,000 miles from the Moon.
After testing its maneuvering ability at L2, engineers are now moving it back to lunar orbit for further tests.
China lifts export limits on rare earth minerals
Having lost its case before the World Trade Organization China has lifted the limits it had placed on the export of rare earth minerals back in 2009.
Because of low costs, China produces about 90% of all rare earths worldwide, needed for most high tech electronics. This decision eases a concern that has existed now for better part of a half decade.
SpaceX job offers posted for Brownsville Texas
Want to work for SpaceX? You can! They are now posting job openings for those who want to work at their new spaceport in Brownsville Texas.
Some details on the SpaceX’s attempt to land its Falcon 9 first stage
This SpaceX press release gives some good info on the difficulty they face getting the first stage on Tuesday’s Dragon launch to land successfully on its floating sea platform:
To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.
They are going to try however, and they will be filming their attempt all the way. Stay tuned for some very interesting footage.
Why the pause in global temperature rise?
The pause in global temperature rise has now lengthened past 18 years, and climate scientist Fred Singer asks some good scientific questions why.
Global warming skeptics like myself have been quick to note the long pause in any temperature increase since 1998, the lack of which has essentially invalidated all the climate models put forth by the global warming activists in the climate community. Singer goes one step further, however, asking the next question: Why has the temperature not risen? He doesn’t know, but he does put forth a number of suspects that the good scientists in the climate field should be pursuing, assuming they can open their eyes and work with real data for a change.
As usual, it isn’t as simple as we would like. The sun for example might explain it, but so could a lot of other factors, including a number put forth by global warming advocates. Good science demands that we look at them all, and find out the truth, rather than cherry-pick our favorite answer and ignore all other evidence.
Weather reports moderately favorable for Tuesday’s Falcon 9 launch
The weather for Tuesday morning’s SpaceX launch of Dragon/Falcon are presently 60% favorable.
If all goes right, SpaceX will also try to bring the first stage back to a vertical soft landing on a ocean-going platform. If they succeed, they will immediately revolutionize the entire space launch industry.
Korean satellite threatened by space junk
Debris left over after the collision of U.S. and Russian satellites in 2009 threatens to hit a South Korean research satellite Sunday evening.
It appears that their options to prevent impact are limited. They are adjusting the satellite’s attitude to reduce its footprint relative to the junk, but do not seem capable of shifting its orbit enough to avoid the junk completely.
