Astronomers have discovered an exoplanet smaller than Earth

11:45 am

Worlds without end: Scientists have measured the size and mass of the smallest exoplanet yet, a Mars-sized planet orbiting a star about 200 light years away.

The planet, named Kepler-138 b, is the first exoplanet smaller than the Earth to have both its mass and its size measured. It is one of three planets that orbit the star Kepler-138 and that pass in front of it on every orbit as viewed from Earth — a maneuver that astronomers call a transit. “Each time a planet transits the star, it blocks a small fraction of the star’s light, allowing us to measure the size of the planet,” said Dr. Daniel Jontof-Hutter, a research associate in astronomy at Penn State who led the study.

“We also measured the gravity of all three planets, using data from NASA’s Kepler mission, by precisely observing the times of each transit,” Jontof-Hutter said. The astronomers also were able to measure the masses of these planets. “Each planet periodically slows down and accelerates ever so slightly from the gravity of its neighboring planets. This slight change in time between transits allowed us to measure the masses of the planets,” Jontof-Hutter explained. After measuring both the mass and size of an exoplanet, astronomers then can calculate its density and its bulk composition.

OPM ignored warnings last year its computers were insecure

10:19 am

An inspector general report last year had advised OPM to shut down many of its computer systems because they were running without sufficient security. The agency ignored that recommendation.

In the audit report published November 12, 2014, OIG found that 11 out of 47 computer systems operated by OPM did not have current security authorizations. Furthermore, the affected systems were “amongst the most critical and sensitive applications owned by the agency.” Two of the unauthorized systems are described in the report as “general support systems” which contained over 65 percent of all OPM computer applications. Two other unauthorized systems were owned by Federal Investigative Services, the organization which handles background investigations in connection with government security clearances. OIG warned bluntly, “any weaknesses in the information systems supporting this program office could potentially have national security implications.”

Because of the volume and sensitivity of the information involved, OIG recommended OPM “consider shutting down systems that do not have a current and valid Authorization.” But OPM declined, saying, “We agree that it is important to maintain up-to-date and valid ATOs for all systems but do not believe that this condition rises to the level of a Material Weakness.”

The head of OPM also claimed in House hearings yesterday that their failure to close these systems down was justified since the hackers were already in the system when the recommendation was made.

In other words, we didn’t do anything to make the system secure, and when hackers broke in it was further justification for not doing anything.

Yeah, let’s put our healthcare under their control also!

UrtheCast releases its first commercial videos of Earth

9:33 am

The competition heats up: UrtheCast has released high resolution videos of three Earth cities taken from its camera on ISS.

Take a look. The cameras are quite successful in capturing the motion of vehicles on highways and road, which is amazing considering the vibrations that ISS experiences merely from astronaut movements.

The company plans to offer the imagery in several tiers, from a free video feed on its website to an API that will allow customers, including corporations, governments and individuals, to purchase imagery data from its database or make real-time requests for a look at a given spot on the earth. The cameras scan the ground under the ISS, which tracks the earth between about 51 degrees north and south latitude.

France sells Arianespace to Airbus Safran

9:16 am

The competition heats up: In negotiations resulting from increased competition in the launch industry, France and its space agency have agreed to sell their stock in Arianespace to Airbus Safran, builders of the new Ariane 6, giving that private company 74% ownership.

I have reported on this deal earlier. This report makes it clear, however, that Arianespace will essentially become irrelevant after the deal is completed. Airbus Safran will build and own the rocket, and will be in charge.

Saudia Arabia and Russia sign space exploration agreement

9:01 am

The competition heats up: Saudia Arabia has signed a deal with Russia to work together to explore space for peaceful purposes.

This deal has less importance to the exploration of space. Instead, it signifies clearly the worsening relations between the U.S. and Saudia Arabia. For decades the Saudis would always turn to the U.S. for such deals. They are now looking elsewhere, having found the U.S. to be an unreliable partner during the Obama administration.

Rosetta repositions to improve contact with Philae

8:52 am

Engineers have begun shifting Rosetta’s trajectory paralleling Comet 67P/C-G in order to maximize communications with the lander Philae.

Commands to adjust the trajectory were successfully uploaded Monday evening; further commands will be uplinked on Thursday evening. The spacecraft will perform two manoeuvres, one on Wednesday morning and the second on Saturday morning. The effect of the two ‘dog-leg’ burns will be to bring the orbiter to a distance of 180 km from the comet and to reproduce the orbiter-comet geometry of the first contact.

We should therefore not expect further news from Philae for the rest of this week.

Another successful course correction for New Horizons

9:31 pm

New Horizons has successfully completed another course correction and is shipshape for its fly-by of Pluto on July 14.

A 45-second thruster burst on June 14 refined New Horizons’ trajectory toward Pluto, targeting the optimal aim point for the spacecraft’s flight through the Pluto system. This was only the second targeting maneuver of New Horizons’ approach to Pluto; Sunday’s burst adjusted the spacecraft’s velocity by just 52 centimeters per second, aiming it toward the desired close-approach target point approximately 7,750 miles above Pluto’s surface.

The maneuver was based on the latest radio tracking data on the spacecraft and range-to-Pluto measurements made by optical-navigation imaging of the Pluto system taken by New Horizons in recent weeks.

Right now all looks good for the fly-by.

Federal government has no system for verifying Obamacare subsidies

3:59 pm

Finding out what’s in it: An audit by the inspector general of Health and Human Services (HHS) has found that the agency has no internal system to verify that $2.8 billion in Obamacare subsidies were paid correctly, or even to the right people.

The [inspector general] said the agency did not have a system to “ensure that financial assistance payments were made on behalf of confirmed enrollees and in the correct amounts.” In addition, [HHS] relied too heavily on data from health insurance companies and had no system for state-based exchanges to “submit enrollee eligibility data for financial assistance payments.”

The government does “not plan to perform a timely reconciliation” of the $2.8 billion in subsidies. [emphasis mine]

Not only have they given out billions without proper record-keeping or proper verification, the agency has no intention of fixing the problem. “Ain’t my job, man!”

Anti-drilling environmentalists trash environment during protest

3:46 pm

Environmental activists protesting the launch of a drilling rig in Seattle did serious damage to a nature reserve, costing $10K to clean it up.

I am not surprised. The left and environmental movement has this annoying habit of blaming everyone else for the world’s problems, insisting that only they have the solutions. When their solutions fail, or when they screw up, however, they are never willing to admit their error, take personal responsibility, and look for a more effective solution. To them, it is always someone else’s fault.
