In the heat of competition: The first test flight of SpaceX’s Falcon Heavy rocket has been pushed back from the end of this year until April 2016.
This isn’t surprising after the June 28 launch failure. They have to get the Falcon 9 up and running before they can consider launching the first Falcon Heavy.
The competition heats up: ISRO has successfully completed another long duration firing of its home-built high-thrust cyrogenic rocket engines.
Before its planned flight late in 2016, they will do more engine burns, this time while simulating conditions at high altitude.
An evening pause: I posted this performance back on November 23, 2010, had forgotten, and found it again by accident. It bears another viewing. As noted at the youtube link,
Judy Garland only performed “Over The Rainbow” twice during her many television appearances, which spanned 14 years. She performed it on her first TV Special, “Ford Star Jubilee” in the episode called “The Judy Garland Special” in 1955, and sang it to her children on The Christmas Edition of her weekly TV show “The Judy Garland Show” (1963).
Here Judy is dressed up [in the first special] as the tramp character she played when doing a duet with Fred Astaire in the film ‘Easter Parade’.
Watch. It shows why she was both a great singer and a great actress.
The investigation into the failure of the Falcon 9 launch June 28 now thinks the cause was a failed strut in the upper stage.
The struts are 2 feet long and about an inch thick at its thickest. SpaceX does not make the struts, a supplier does. From now on, each one will be individually checked, Musk said, and the design and material may be altered for added strength. The struts are designed to handle 10,000 pounds of force at liftoff; at the time of the accident, they would have been seeing only 2,000 pounds of force. A failure at such a low threshold is “pretty crazy,” Musk said. The strut most likely failed at its attachment point, he added.
Another change: Beginning with its next launch, each Dragon cargo carrier will be equipped with software for deploying its parachutes. The Dragon destroyed last month, along with an estimated $110 million worth of NASA equipment and supplies, would have survived if the parachutes normally used for descent at mission’s end could have been activated, Musk said.
The investigation is still not finalized, but is likely close to completion.
Democracy in action! Iran’s parliament is likely to demand changes to Iran deal before voting for its approval.
The ironies here are tragic. While their parliament stands up for its constitutional rights, our Congress, run by Republicans, has ceded its power to the President, with the Senate giving up its constitutional right to only approve treaties with a two-third majority. Instead, they got down on their knees and handed Obama the power to make this very bad treaty without their full consent. What idiots.
Russian internet entrepreneur Yuri Milner has given SETI $100 million for a ten year project to accelerate their effort to search for evidence of extraterrestrial life.
Understanding why SETI needs private funding is important:
SETI has been going on since 1960, when radio telescopes became sensitive enough to detect signals from another planet if it was broadcasting signals similar to those which our civilization does. Researchers developed devices that could monitor millions of frequencies at once for any signal that looked at all different from that produced by astronomical objects or the natural background. At first funded by universities and NASA, public funding for SETI was axed by Congress in the early 1990s. Since then, the nonprofit SETI League has received funding of a few million dollars a year from private donors.
Congress correctly cut the funds because it isn’t really the business of the federal government to search for alien life. Some taxpayers really don’t want their money used for that purpose, and they should have the right to say no. Instead, Congress essentially told SETI to do it right: Get private funding from people who want the research done. The work will be done more efficiently for less, and no one will be required to contribute who doesn’t want to.
Milner’s contribution now is the biggest donation yet, and suggests that interest in this research is building culturally.
The competition heats up: Faced with the possibility that the Russians might eventually end their lease arrangement combined with a desire to make money, Kazakhstan is now planning to make the historic Baikonur spaceport available to tourists.
Why they haven’t done this years ago is baffling. But then, this is Russia and Kazakhstan, not the U.S.
Engineers on the Rosetta team are struggling to figure out why they cannot get a solid communications lock with their Philae lander, and have come up with several explanations.
One possible explanation being discussed at DLR’s Lander Control Center is that the position of Philae may have shifted slightly, perhaps by changing its orientation with respect to the surface in its current location. The lander is likely situated on uneven terrain, and even a slight change in its position – perhaps triggered by gas emission from the comet – could mean that its antenna position has also now changed with respect to its surroundings. This could have a knock-on effect as to the best position Rosetta needs to be in to establish a connection with the lander.
Another separate issue under analysis is that one of the two transmission units of the lander appears not to be working properly, in addition to the fact that one of the two receiving units is damaged. Philae is programmed to switch periodically back and forth between these two transmission units, and after tests on the ground reference model, the team has sent a command to the lander to make it work with just one transmitter. As Philae is able to receive and accept commands of this kind in the “blind”, it should execute it as soon as it is supplied with solar energy during the comet’s day.
They have heard from Philae since July 9. Because of comet activity they have had to pull Rosetta back away from the nucleus to protect it, and are now focusing its primary activity on observations, not communications with Philae. They will continue to try to bring Philae back to full functioning life, but the priority is now the comet.
Cool image time! NASA’s DISCOVR solar observation probe has released its first image of the Earth, taken from its station-keeping position a million miles from Earth.
This camera was originally designed for Al Gore’s proposed propaganda mission where a spacecraft would take daily pictures of the Earth to pound home his environmental agenda. Eventually NASA found a real use for the satellite’s overall structure and location, observing the Sun’s activity and give us advance warning of dangerous flares or coronal mass ejections.
They left the Earth-viewing camera on board, partly because it was built already (it would cost money to remove) and partly because daily images like this can be of some scientific value.
After a several week pause while engineers analyzed the issue that caused the spacecraft to go into safe mode on June 30, they have now resumed their descent to a lower orbit to take higher resolution images of Ceres.
The spacecraft experienced a discrepancy in its expected orientation on June 30, triggering a safe mode. Engineers traced this anomaly to the mechanical gimbal system that swivels ion engine #3 to help control the spacecraft’s orientation during ion-thrusting. Dawn has three ion engines and uses only one at a time. Dawn’s engineering team switched to ion engine #2, which is mounted on a different gimbal, and conducted tests with it from July 14 to 16. They have confirmed that the spacecraft is ready to continue with the exploration of Ceres.
An evening pause: For those who like modern soft jazz.
Hat tip Danae.
Finding out what’s in it: After Obamacare`s government help for insurance companies ends and consumers have bear the full cost of this monstrous law, the costs will skyrocket again.
By 2023, I estimate that the average family plan could be 61% more expensive than it is in 2015, with individual plans only one or two percentage points behind. These increases are so high that direct taxpayer subsidies to consumers are unlikely to keep up. So the cost, both financially and politically, will become increasingly intolerable.
Thank you Obama and the Democratic Party for bringing us this present. We couldn`t have done it without you!
