Another balanced rock!

A new balanced rock

Cool image time! The image to the right, cropped to show here, was taken by Curiosity’s mast camera this week as it surveys the upcoming terrain so that scientists can choose its route. It shows another balanced rock that is far more unbalanced than the one the rover passed last week.

In reviewing the survey images, I am not exactly sure whether this rock is located along Curiosity’s future route, as I have not been able to locate it in any of the panorama images the rover has taken. If it is in the gap they are aiming for, then we shall soon see some additional close-ups. If not, then we will have to content ourselves with some other views that, when you think about it, are really just as good.

A visit to OSIRIS-Rex clean room

8:56 am

NASA recently gave a press tour of the clean room where the asteroid probe OSIRIS-Rex is being prepped for its September 8 launch, and one reporter from that tour wrote a very nice description of what it was like.

After such a tour, most reporters write up stories that describe the spaceship, its mission, and its status. This reporter however did something better. He wrote up what it’s like to enter a clean room for a mission only weeks from launch.

Our belongings have been lined up in a row alongside us. And then the dog arrives.

It’s a beautiful specimen of a german shepherd, long and enthusiastic, being led by a sturdy military-type with a buzzcut wearing what looks like mercenary gear. The dog is led down the row of belongings once. Then twice. Then he and his owner head back to their truck and drive off. We have passed. We are free to go into the blessed blast of cool air on the bus that’s been idling alongside us for what seems like hours, but has really only been about 15 minutes.

And that’s only the start. Read it all. Quite fascinating.

Virgin Galactic, an expert in diversity!

8:48 am

Private vaporware: Virgin Galactic can’t seem to get its SpaceShipTwo off the ground but, darn it, the company, in partnership with the International Symposium for Personal and Commercial Spaceflight (ISPCS), sure can run a diversity workshop!

While charging each attendee $500 for the privilege! This quote from the link above illustrates where Virgin Galactic appears to be placing its focus:

Virgin Galactic’s Executive Vice President of Spaceport and Program Development, Jonathan Firth, recently spoke to us about the industry’s need to expand behaviours and devise new ways to embrace a more diverse and inclusive workforce. “Presently only 16 per cent of the space industry workforce are female. In order to strengthen our industry and our chances of achieving great things long term we need to change this. We need to refocus on how crucial it is that we, as a company, an industry, a planet, are proactively encouraging a wide ranging of workforce from all walks of life, geographical locations, academia, gender and race. We’re sure that the event will share some incredibly informative and surprising truths about why some teams thrive and others falter,” said Jonathan.

Then there’s this quote from this news report about the workshop:

Lastly, Virgin Galactic and the ISPCS ask the public to consider “What does success look like, without self at the center?”

To me, success for a space tourism company is flying its ships and passengers in space, not spending its time focusing on the race and gender of its employees. So far, it appears that Virgin Galactic does not yet understand this.

Fossilized rivers on Mars

8:17 am

The uncertainty of science: Using high resolution images from Mars Reconnaissance Orbiter scientists have identified more than 10,000 miles of fossilized rivers on Mars.

The new study examined images covering an area roughly the size of Brazil at a much higher resolution than was previously possible – six metres per pixel compared to 100 metres per pixel. While a few valleys were identified, the team revealed the existence of many systems of fossilised riverbeds which are visible as inverted channels spread across the Arabia Terra plain.

The inverted channels are similar to those found elsewhere on Mars and Earth. They are made of sand and gravel deposited by a river and when the river becomes dry, the channels are left upstanding as the surrounding material erodes. On Earth, inverted channels often occur in dry, desert environments like Oman, Egypt, or Utah, where erosion rates are low – in most other environments, the channels are worn away before they can become inverted. “The networks of inverted channels in Arabia Terra are about 30m high and up to 1–2km wide, so we think they are probably the remains of giant rivers that flowed billions of years ago. Arabia Terra was essentially one massive flood plain bordering the highlands and lowlands of Mars. We think the rivers were active 3.9–3.7 billion years ago, but gradually dried up before being rapidly buried and protected for billions of years, potentially preserving any ancient biological material that might have been present,” added Joel Davis.

These geological forms are different than most of the more well-known Martian channels in that they are not channels but meandering riverlike ridges, higher than the surrounding terrain. Arabia Terra, where they are located, is a transition region in the northern mid-latitudes between Mars’s southern highlands and its northern flat plains, where some believe an ocean once existed.

North Korea fires a ballistic missile from submarine

12:08 am

North Korea today successfully launched a ballistic missile from a submarine, landing it within Japanese waters.

In addition, North Korea on Monday threatened to launch a nuclear attack on the U.S.

North Korea warned Monday that it would launch a preemptive nuclear attack against the U.S. and South Korea if they showed the “slightest sign of aggression” toward Pyongyang while conducting their annual military drills. The North’s Foreign Ministry said its “first-strike” units are prepared to conduct retaliatory strikes on South Korean and U.S. forces, threatening to turn the two nations into “a heap of ashes.”

Don’t worry however. The Obama administration “strongly condemned” the test launch today. That will certainly make a difference.

China unveils its 2020 Mars lander/rover

7:06 pm

The competition heats up: China today released design concepts of its planned 2020 Mars lander and rover.

According to Ye Peijian, one of China’s leading aerospace experts and a consultant to the program, the 2020 mission will be launched on a Long March-5 carrier rocket from the Wenchang space launch center in south China’s Hainan province. The lander will separate from the orbiter at the end of a journey of around seven months and touch down in a low latitude area in the northern hemisphere of Mars where the rover will explore the surface.

If they succeed they will have definitely moved ahead of Russia in the ranks of space-faring nations.

The bigots in academia

9:34 am

Two stories today that only confirm what many other previous stories have shown: Modern academia is very bigoted, but instead of favoring white supremacy their focus is promoting black and minority rule.

The second story outlines efforts to create segregated housing and classrooms for the benefit of minorities at a number of different colleges.

It is important to remember that each one of these proposals is being put forth by leftwing academics, all of which I guarantee are partisan Democrats. All they can see is race, which is why they call anyone that disagrees with them a racist. Or to quote the Bible, “And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye?”

Unknown new British company will fly space tourists in five years

9:03 am

Private vaporware: A new and previously completely unknown British rocket company, Starchaser, has claimed today that it will be flying tourists into space within three to five years.

How do I know this is vaporware and won’t happen? Besides the fact that I’ve never heard of this company before and that the story above includes a lot of fishy details (such as the head of the company has apparently most spent his time building large model rockets), there was this one quote:

The flight will only take an hour and will see the rocket reach around 330,000ft – ten times the average cruising altitude for an aeroplane flight.

An hour is too short for an orbital flight, and is much too long for a suborbital flight at 330,000 feet. In other words, something here is just not right. Regardless, I hope my cynicism here turns out to be wrong, and this company joins the new competition to lower costs into space.

Russia reveals its proposed new cargo spacecraft

8:57 am

Government vaporware: In an effort to save money Russian engineers have designed a new cargo spacecraft to replace the Progress freighter.

Faced with latest economic problems, and the need to reduce the number of Progress cargo launches, Russia’s space agency Roskosmos made plans to cut the permanent crew of ISS cosmonauts from three to two people. However the full international crew on the ISS is supposed to include six people with half of it reserved for Russia.

To resolve this supply problem, Roskosmos ordered RKK Energia, its key contractor responsible for human spaceflight, to prepare a preliminary design of a bigger cargo ship by the end of this month. Engineers quickly put together this proposal that would combine off-the-shelf hardware with new technology. … The most important new feature of the proposed cargo ship will be the six-tank cluster to carry more than 1.8 tons of propellant to the station. It will simultaneously serve as a tanker for the space station while also feeding the ship’s own propulsion system. As a result, the new design provides significant mass savings in comparison to the current Progress ships, which need two separate sets of tanks for refueling and maneuvering.

The main engine for the new cargo ship will be borrowed from an existing satellite. Meanwhile, 28 small thrusters for orbit correction and maneuvering will be copied practically unchanged from the Progress.

They hope to fly this new freighter by 2020. I’m willing to bet anyone that this won’t happen.
