MOSCOW - An unmanned supply ship burned up on re-entry over the Pacific Ocean Friday, a week after the spacecraft suffered a communications failure, the Russian space agency said.
"The Progress M-27M spacecraft ceased to exist at 05:04 Moscow time (0204 GMT) on 8 May 2015. It entered the atmosphere... over the central part of the Pacific Ocean," Roscosmos said in a statement.
Almost all similarly-sized spacecraft disintegrate in the atmosphere or land in the oceans, which cover most of the Earth's surface.
The spacecraft, a Soviet design generally known for its reliability, blasted off for the International Space Station on April 28 carrying oxygen, water, spare parts and other supplies for the orbiting space laboratory, which has a crew of six international astronauts.
A few hours after the launch, mission control lost contact with it.
A special commission is looking into the incident, the deputy head of Roscosmos has said.
Sources in the space industry told Russian news agencies that the accident was caused by a problem with the Soyuz rocket carrying the cargo ship into orbit, rather than the supply vessel itself.
Russia has recently suffered a series of glitches exposing shortcomings in its space programme.
A Progress supply ship crashed in Siberia shortly after launch in 2011. Moscow has also lost several lucrative commercial satellites.

The problem was most likely in the upper stage. That engine is an old and very reliable design. However they have upgraded the electronics controlling that engine and at this moment it seems that new controller did not work as it should.
That is what is happening all over. The old components do well, but recent upgrades are unreliable. However they are no longer able to produce some of the older components, they have to upgrade.
Sometimes I like to talk about developments that are somewhat off the chart.
There is a new one that has the scientific community buzzing as well as the fan community.
It is the EM-drive. A propellantless drive that would open the whole solar system for manned flight, if it works. The problem is that it seems to violate laws of nature, the law of conservation of momentum, no less. We all know that this law is basic to the very existence of our universe.
It is based on fluctuations of the quantum vacuum. A drive that seems to be working has first been demonstrated by a chinese team. Now a new design has been built by Eagle Works, a study group of NASA, no less that worked as well, and then because it was argued it is a false positive because it was tested in atmosphere, they tested it in vacuum and got the same results.
Thrust is miniscule though so measurement error is still possible. They are working on a new enhanced, more powerful version. If that works, another lab will test the design for peer review.
Unlike other seemingly revolutionary developments this team is very open, giving very detailed descriptions of what they are doing, inviting criticism and possible faults that cause false positive results.
The tests have already conclusively refuted the scientific concept that led to building the device. But while the theory is wrong, it still seems to work.
While I remain sceptic, I cannot but hope the drive will be proven over the next few months. If that happens, the theoretical physicists will have decades of work ahead of them to explain how it works.
A short but comprehensive description of what has been done so far.

An article on the EM-drive on Nasaspaceflight.com
Evaluating NASA?s Futuristic EM Drive | NASASpaceFlight.com
In this article Chris Bergin seems to have gone somewhat over the top which is not his usual mode of operation.
That's the drive.
https://teakdoor.com/images/imported/2015/05/376.jpg
The power generating device of the NASA drive is a magnetron. You can buy one off the shelf in the price range of 50$. That would be 1kW and give thrust enough to prove the concept. However to build an efficent drive that would really be good for driving space ships you would need a 100kW generator which will be somewhat more expensive.
The chinese experiment used something even more basic. They used a microwave generator as found in a kitchen microwave oven. The NASA Eagleworks team however believes a magnetron for microwave production will be more efficient.
After the accident of Progress M-27M the russian space agency delays the next manned flight which is using a similar launch vehicle. The launch is now scheduled for late July. The present ISS crew will stay about a month longer in orbit.
They are trying to advance the flight of the next Progress transporter to early July so that would test the launch vehicle unmanned before they send up the next crew.
Worst case if that fails they may have to reduce the ISS crew. They always have a Soyus spacecraft at the ISS that can bring down the crew.
This shows how bad the situation is because the USA don't have their own crew capacity after the end of the SpaceShuttle. If development of a replacement capability proceeds as planned there will be two new US vehicles ready to fly in 2017. That date has slipped a lot because the US Congress did not fund the development as requested by NASA and the presidential budget.
In fiscal year 2016 for the first time the development program will get funding at the requested level.

Two fresh failures of russian space.
Another proton failed. It seems to have dropped somewhere in China. Launch video seems to show some problem immediately after launch. But worse news is that a Briz upper stage failed. That is the same family of upper stages that failed on the last Progress resupply mission for the ISS and is needed for Soyuz manned flights as well. The flight was carrying MexSat-1 a satellite built by Boeing for the mexican government.
ÔÅÄÅÐÀËÜÍÎÅ ÊÎÑÌÈ×ÅÑÊÎÅ ÀÃÅÍÒÑÒÂÎ (ÐÎÑÊÎÑÌÎÑ)|
Also a planned ISS reboost failed for yet unknown reasons.
Until they fix this unreliable upper stage the existence of ISS may be in jeopardy. The last sentence is my personal comment only.
The youtube video of the start. Look around 20s into the video for first indications of problems.

They do have an escape system. However the conditions on escape are so harsh that it is survivable but barely and likely to cause lasting damage. The same is true for the old Apollo launch escape system though. SpaceShuttle did not have an escape system at all.

Planetary Society readies first test flight of solar sail technology
LightSail-1 will pave the way for future spacecraft to take advantage of cosmic solar winds for propulsion.

On May 20, a spacecraft roughly the size of a toaster will hitch a ride aboard an Atlas V rocket and soar to an altitude of 450 miles above Earth. Called the LightSail-1, the decades-in-the-making, privately funded $1.8 million mission from the Planetary Society will be the first step in testing a solar sail as a means of spacecraft propulsion.
"LightSail is technically wonderful, but it's also wonderfully romantic. We'll sail on sunbeams," Planetary Society CEO and "Science Guy" Bill Nye said in a statement earlier this year. "But wait, there’s more: this unique, remarkable spacecraft is funded entirely by private citizens, people who think spaceflight is cool."
I previously wrote about this mission in late January, but solar sail technology is back in the news thanks to a video posted by the Planetary Society featuring its co-founder, the late great astronomer Carl Sagan, appearing nearly 40 years ago on "The Tonight Show with Johnny Carson." In it, Sagan talks about solar sails and their potential to revolutionize space travel.
"There's a tremendously exciting prospect called solar sailing, which travels on the radiation and particles that come out of the sun — the wind from the sun," Sagan told Carson. "It works exactly as an ordinary sailboat does, so it can go out from the sun, it can tack inwards to the sun, and because it has a constant acceleration it can get you around the inner part of the solar system a lot faster and a lot more conveniently than the usual sorts of rocket propulsion."
While LightSail-1 won't achieve an orbit high enough to take advantage of solar radiation, it will unfurl its 344 square feet of Mylar sails as a proof of concept. Should all go well, the Planetary Society will prep the launch of LightSail-2 for a full-fledged solar sail flight in 2016.
"It's just an extraordinary idea," Sagan told Carson. "And there might be a time when we start doing it for planetary regattas. It's a whole new kind of idea."
We can't wait to see Sagan's vision come to life. You can check out a live stream of the May 20 launch event here.

Does Bill look like an evil villain from a James Bond movie?
I would like to write a little more about the situation in russian space activities and my source for the informations.
Most of what I know is from a man who used to work in russian space industry during Soviet times. He is from a former Soviet Republic now independent. He still has contacts, is still a fan of space, russian and in general, and knows a lot even though he now lives in the West and no longer works in space industry. He is also extremely critical of Putins regime. Also many things he says I take with an appropriate grain of salt. He often talks about plans and developments of Roskosmos as if they are on the verge of realization, while in reality they are little more than drafts of ideas with little chance of realization.
The russian space industry and the russian counterpart to NASA, Roskosmos are in a deep crisis. However he says, that the structure is in a process of change. Very good people are now at the top. It will likely get better, but change so fundamental will need time, so still bad years ahead.
CNN on Chinas Space Program
CNN gains exclusive access to China's space city - CNN Video
I recommend clicking the link and looking the video.
Link to the article.
http://edition.cnn.com/interactive/2...d/china-space/
Quote:
The sprawling complex in the north west of Beijing shares the same nondescript character of government compounds throughout China.
But look closer. Guard posts over here; military sentries checking IDs over there.
This is no ordinary facility. Space City is home to the Chinese government's most ambitious and expensive mega-project ever. They've dubbed it "Project 921," the manned-space program.
And foreign journalists are almost never let in.
After more than a year of phone calls and faxes, here we are, inside the simulation room of the astronaut training center.
The astronauts stride into the room according to rank: Nie Haisheng, Zhang Xiaoguang and Wang Yaping.
They're three of China's best-known astronauts and the crew of the 2013 Shenzhou-10 mission, China's longest manned spaceflight yet.
They're roughly the same height and build in their blue jumpsuits and black military boots.
That's no accident. Chinese astronauts are all People's Liberation Army pilots and officers, they have university degrees, they are Communist Party members. And they need to be around the same height and under a certain weight.
You don't need to be superhuman to be an astronaut, says Commander Nie.
"We are just ordinary people," he says, "But, yes, certain aspects make us more suitable to fly space missions."
China's space program was first announced in the early 1970s, but the chaos of the Cultural Revolution stopped it in its tracks.
The program accelerated again in the early 1990s and space administrators picked two classes of astronauts in 1998 and 2010.
All of the crew of the 15-day Shenzhou-10 mission was passed over for missions at least once.
"When I wasn't selected for a mission, there was nothing I could do about it, so I just kept looking forward," says Zhang.
Zhang is the self-described joker of the group, able to lighten the mood during high-pressure situations. Still, he says he had to live through years of disappointments.
"I trained in this simulator for 15 years and I was in space for 15 days. So literally a day in space was a result of a year of training on the ground."
Perhaps the most famous of the group is Wang Yaping. She conducted a live space lecture for 60 million students across China during the mission.
"I remember, I watched the launch of the first Chinese astronaut into space with my fellow pilots," says Wang, who flew a transport plane for the PLA.
"I saw the fireball come out of the rocket and a thought just popped into my head: 'The first Chinese man just flew into space. When will the first female astronaut from China get there?'"
After years of training, you would think that it is all about the mission. But what happens when the space lectures and experiments are over?
"We really enjoyed the zero gravity situation in our spare time," says Wang. "It allowed us to practice tai chi upside down, it allowed us to float around like fish."
I too believe it is a grave mistake to keep China out of the ISS. It seems like the hobby horse of a single but influential US Senator. I don't think China is in a Space Race. But they are slowly but steadily building their program. Based on russian space tech but improving on it.Quote:
China's space program started late and is only now passing milestones the U.S. and Russia clocked years ago.
But, with the backing of the highest echelons of the Chinese Communist Party, it's going into space at a time when other world powers have scaled back on space exploration because of budget restraints or shifting priorities.
U.S. space technology is still "hands down the best in the world," says Joan Johnson-Freese, a professor at the U.S. Naval War College, but she says the U.S. lacks the political will to fund an ambitious manned spaceflight program, China's is the pride of the nation.
"It would cost the US $140 billion for a true moon and Mars exploration mission but sticker shock would kill it instantly," she says.
"In terms of perception, America has already ceded its leadership in exploration to China."
Inside Space City, Commander Nie -- who leads the manned space mission -- is more diplomatic.
"The United States and Russia started their programs early. They are the pioneers," he says.
"Our space development is not because of some space competition or trying to overtake anyone."
But the modern race to the stars is not just about money, it's driven by technological advances and cooperation.
The International Space Station (ISS) houses a veritable United Nations in space with 15 countries contributing including the U.S., Russia and Japan.
But not China.
China's 21 astronauts are locked out of the ISS, largely because of pressure from U.S. legislators.
In 2011, Congress banned NASA from working bilaterally with anyone from the Chinese space program on national security concerns.
But a recent exhaustive report for the U.S.-China Economic and Security Review Commission says China's improving space capability "has negative sum consequences for U.S. military security."
"China is viewed as a foe, it is viewed as a government that seeks to take our intellectual property, national secrets and treasure and thus Congress is not willing to partner with them," says CNN space and aviation analyst Miles O'Brien.
"I think it is ultimately a mistake."
The Chinese government says its space program is peaceful and already cooperates with other nations.
The crew of the Shenzhou-10 seem keen to work with NASA.
"As an astronaut, I have a very strong desire to fly space missions with astronauts from other countries. And I look forward to the opportunity go to the International Space Station," says Nie.
He says foreign astronauts are welcome to visit China's own space station once it is launched.
The Chinese expect to finish their space station by 2022 -- around the time the International Space Station runs out of funding, potentially leaving China as the only country with a permanent presence in space.
"They are on a slow steady campaign. I think in the end, tortoise versus hare style, they will probably win," says O'Brien.
They're idiots. Only about 5 years ago, they shot down one of their own satellites as target practice, littering a huge orbit with debris.

Due to a software glitch contact to the satellite was lost. Their last hope was that some high energy particle of cosmic radiation would hit the computer in a way that it causes a reboot. This has now happened. The satellite started working again and contact was reestablished. They hope to unfurl the solar sails in a few days. There are still some problems but they are hopeful they can solve them.

A review of the Proton/Progress transporter has been completed. The translation of the statement of the russian Space Agency Roskosmos on Spacenews.
Russian Statement on Proton Failure Leaves Questions - SpaceNews.com
The most worrying aspect is the "number of deficiencies in the enterprises' Quality Management System. It will take time to address them. There is also a blame game going on where responsibility is shifted on a few persons, not to say scapegoats. Firing them will NOT solve the problems.Quote:
The Roscosmos Agency Commission investigating the failed launch of the Proton-M with the Centenario spacecraft May 16, 2015 from Baikonur Cosmodrome announced the outcomes of its work.
The commission members (representatives of the customer, Roscosmos and the Russian Federation Ministry of Defense, heads of industry R&D institutes and production facilities) performed an analysis of the Proton-M and its components manufacturing process, the process of acceptance, transportation, testing and processing, as well as telemetry and ranging information.
Conclusion: Abnormal termination of the Proton-M flight was caused by the Stage 3 Steering Engine failure due to increased vibration loads occurring as a result of the imbalance of the turbo pump unit rotor caused by the degradation of its material properties at high temperatures, and improper balancing.
By the order of Roscosmos head Igor Komarov, Khrunichev Space Center and its subsidiaries are developing an action plan to address the causes of the accident, which includes:The Commission also identified a number of deficiencies in the enterprises’ Quality Management System. An action plan to address these will be developed within a month.
- Changing materials used for the turbo pump rotor shaft manufacturing;
- Revision of the turbo pump rotor balancing techniques;
- Upgrade of the steering engine turbo pump mount to the main engine frame, and others.
The date of the Proton-M next launch will be announced by Roscosmos in June 2015.
I want to say again, that changes are already in the process but it will take years to stabilize the system and improve on present practice.
There's a couple of new innovations in solar sails, one is a new fabric construction that is stronger, lighter and expands in a more controlled motion, and the other is they found graphene when hit by a light particle gives back extra energy, which would add propulsion above that of the effect of sunlight alone. Don't know the details but they're out there.

The story behind it. Someone found debris of a fairing in the sea at the Bahamas and it included a GoPro camera attached to it. Until that find it was unknown that there are cameras in the fairing. After it became known SpaceX released this video. A must see, just beautiful.
SpaceX had announced that they are working on recovering and reuse of the fairings. That's probably why the cameras are there.
New video released by NASA from images by the Dawn probe now orbiting this Dwarf Planet.
Mysterious are the bright spots. Speculation is they are water ice uncovered by recent impact of small meteorites. NASA scientists are declining to comment at this time before they have more data. Ceres is expected to have a very high amount of water.
It is computer animated but with real images from Dawn. This is only the beginning of a long science campaign while orbiting Ceres.

NASA is doing the second test of their LDSL - the Low Density Supersonic Decelerator. It will be tested in the high earth atmosphere. It may be used to decelerate probes for landing on Mars.
https://teakdoor.com/images/smilies1/You_Rock_Emoticon.gif
Here hanging on a crane the LDSL
https://teakdoor.com/images/smilies1/You_Rock_Emoticon.gif
The event is presently live on NASA TV. LDSL will be lifted into the stratosphere by a balloon, then accelerated by a small rocket to test its deceleration abilities.
During the live broadcast they talked about the balloon too. It is made of a very light but tough high tech material. Just the same as your shopping bag or garbage bag. :)
That NASA test failed, again. That LowDensitySupersonicDecelerator worked, but the parachute that should decelerate more after that failed. Just like on the first test a year ago. After that failure they redesigned the parachute and really expected it to work this time but it failed again. Problem is physics is against them. They are approaching the limits of what can be done with parachutes.
Probably they get this size to work in the end. But for any major Mars program they will need even much larger payloads and parachutes will not cut it. They will have to go for propulsive deceleration and landing.
To be clear, quite large loads can be landed using parachutes on earth. But this is supposed to work on Mars and the martian atmosphere is so thin that the effect of parachutes is very limited.

Over the weekend, the groundbreaking LightSail satellite unfurled its gigantic solar sail to help propel it through space.
Now, the first images to be beamed back from the satellite prove that it’s really up and running.
Sweet success after many problems have been overcome. They can be proud. The sail will be stretched out more flat and smooth.Quote:

The New Horizons mission.
The probe New Horizons is now closing in on its target after more than 9 years of flight. It launched on Jan. 19 2006. It will make its closest approach to Pluto on July 14 this year. Unfortunately it can make only a flyby. It is too fast to brake into orbit. But during the flyby it will collect a huge amount of scientific data. The data will be stored and then sent to earth over a period of more than a year. Transmission is slow due to limited power for transmission and the large distance. At the time these photos were taken it was still over 50 million km away from Pluto. But these images are alread very much better than anything the largest telescopes on earth or in orbit, like Hubble, can get.
https://teakdoor.com/images/smilies1/You_Rock_Emoticon.gif
After the flyby New Horizons will continue outward into the Kuiper Belt. A new target out there was selected and the exact trajectory of the flyby is being adjusted so it will be sent to that object by Pluto gravity. If everything goes well in many years another object out there can be observed and data and pictures will reach us.
I just checked. The date July 14 2015 for the flyby was already given directly after launch. That's impressive precision after such a long flight.
It seems that it is not a perfect sphere, by any means. Hadn't expected that.

Well, it has been argued it is the decomissioned Imperial Death Star. But there is no positive proof of that yet. Don't rule out the possibility it really is a near perfect sphere with some very dark spots.Quote:

Philae comet lander wakes up - BBC News
Philae comet lander wakes up
The European Space Agency (Esa) says its comet lander, Philae, has woken up and contacted Earth.
Philae was dropped on to the surface of Comet 67P by its mothership, Rosetta, last November.
It worked for 60 hours before going to sleep when its solar-powered battery ran flat.
The comet has since moved nearer to the sun and Philae has enough power to work again, says the BBC's science correspondent Jonathan Amos.
The Rosetta probe took 10 years to reach the comet, and the lander - about the size of a washing-machine - bounced at least a kilometre when it touched down.
Its exact location on the comet has since been a mystery.
However, Esa said on Thursday that it might have located it from images and other data from the mothership.
Wow, I checked on Philae just 2 hours ago and the message was not out at that time.Quote:

Philae active so much nearer to the sun may give better data than had been hoped for. If it had worked as planned it would be long dead by now due to increasing heat from the sun. So much covered from the sun may get philae through the closest approach to the sun (aphelion).
Let's hope it can work for a long time and the scientific instruments are still working nominally.
BTW we have three different missions in the outer solar system in active phases of their voyage this year.

NASA Image Gallery Brings All the Best Space Photos Under One Roof
By Maddie Stone on 22 Jun 2015 at 9:00AM
Ever come across a gorgeous Hubble image, or an article showing some of NASA’s cool new Mars lander tech, and wish you could remember where those lovely photos live? Rejoice, space nerds: NASA is making your life easier than ever, with the launch of a new mega gallery where you can browse all of the space agency’s astronomical eye candy.
The NASA Images collection, built and unveiled last week by Luna Imaging, combines over 70 NASA Image galleries into a single, searchable source. These includes familiar collections such as NASA’s Image of the Day Gallery and the Jet Propulsion Image Gallery, but also plenty of obscure treasures. In total, the collection contains over 100,000 photographs that range from historic documentation of the Apollo moon missions to the latest shots of distant quasars by the Hubble Space Telescope.
“We envision that NASA Images will appeal to space fans, STEM educators, visual resource fans, archive fans, people who appreciate open collections,” a Luna spokesperson told Gizmodo in an email. “We’ve already had some interest in the site from people with GIS and geospatial interests because of the satellite imagery the collection includes.”
As someone who loves to write about space and to simply enjoy new images of the great beyond, I find this to be a splendid idea. Here’s the link one more time, now off with you, you’ve got things to discover!
