ESA approves ExoMars 2020 funding

5:58 pm

Despite the failure of the Schiaparelli lander on ExoMars 2016, the European Space Agency today approved funds to build and fly the ExoMars 2020 rover mission.

At a meeting of European government ministers in Lucerne, Switzerland, on 1 and 2 December, ESA member states agreed to provide an extra €339 million for ExoMars 2020. ESA also announced that it will find a further €97 million by moving funds internally. Speaking at a press briefing after the meeting, ESA director-general Jan Wörner said this would be done “without detriment” to ESA’s wider science budget.

But not all projects were so fortunate. Member states did not commit the €250 million needed to fund a plan for ESA to participate in a mission to deflect the moon of an asteroid, although they left door open to future, similar projects.

I am not at present sure how they are going to divide up the work between Europe and Russia. Earlier it was my understanding that Russia would provide the roving technology, but right now I am very unsure about this.

One side note: At this same meeting ESA committed to sticking with ISS through 2024.

Another captive carry flight test of Virgin Galactic’s Unity

8:56 am

After cancelling a planned first glide test of Virgin Galactic’s Unity spaceship in early November, the company completed a second captive carry flight on November 30.

“As part of our ground and flight testing, we made a few tweaks to the vehicle,” Virgin Galactic tweeted before the Nov. 30 flight. “We’ll test those in a captive carry flight today.” Virgin Galactic has not announced when the next test flight will take place or if it will include a glide test.

They apparently found some issues both from the first captive carry flight as well as ground tests that required them to make some changes to the spaceship and do another captive carry flight.

Japanese company developing suborbital mini-shuttle

8:46 am

The competiion heats up: A private Japanese company is developing a sub-orbital mini-shuttle capable of carrying up to eight people, and hope to fly it by 2023.

An unmanned trial run of the prototype to an altitude of 100 kilometers is scheduled for 2018, and if a manned mission is successfully achieved by 2020, the company hopes to commence its space travel enterprise by the end of 2023. The price of a trip into space is aimed to be about 14 million yen — which is approximately 70 percent of that announced by American company Virgin Galactic. PD Aerospace aims to take passengers to an altitude of 100 kilometers, where they will be able to enjoy a “zero-gravity floating experience” for about 5 minutes, before returning to Earth.

They are entering this competition very late. Considering how slowly Virgin Galactic has moved, though, they still might beat them into orbit.

Japan developing small rocket for commercial smallsats

8:41 am

The competition heats up: Canon has joined a new project by the Japanese space agency JAXA to develop a small rocket for commercial smallsats.

The three-stage rocket is an upgrade to JAXA’s two-stage SS-520, which carries instruments for research observations. Measuring 52cm in diameter and less than 10 meters in length, the new version will cost less than one-tenth as much to launch as leading rockets and is expected to be used to lift microsatellites in orbit. An initial launch is slated for early next year from the Uchinoura Space Center in Kagoshima Prefecture.

Fourth Google Lunar X-Prize team gets launch deal

8:32 am

The competition heats up: TeamIndus, based in India, has signed a contract with ISRO to launch its Google Lunar X-Prize rover as a secondary payload on a Indian PSLV rocket.

This is the fourth X-Prize team to announce a launch contract. According to the rules, the teams have until the end of the year to obtain a contract or else they are out of the competition. We should therefore expect more of these announcements in the coming weeks.

Cygnus fire experiments a success

11:21 pm

The fire experiments that were done on the Cygnus cargo freighter after it left ISS two weeks ago have been declared a success.

Saffire-II burned nine different samples, in an effort to gauge the flammability of various materials in a microgravity environment. These 12-by-2-inch (30 by 5 centimeters) samples included silicon of different thicknesses; a cotton-fiberglass blend; plexiglass; and Nomex, a commercially available material that’s used in spacecraft on cargo bags and as a fire barrier, NASA officials said. Everything went well during the experiment, they added: All nine samples burned as planned, and the Saffire-II team collected more than 100,000 images. All data had come back down to Earth by Friday (Nov. 25), at which point Saffire-II achieved “complete mission success,” NASA officials wrote in an update.

This was the second set of fire tests. There are plans for a third on a future Cygnus freighter.

Buzz Aldrin evacuated from South Pole due to health issue

1:46 pm

Astronaut Buzz Aldrin was today evacuated from U.S. South Pole station due to a worsening health condition.

Aldrin, 86, is in stable condition after “his condition deteriorated” while visiting Antarctica, according to White Desert, which organizes luxury tourism trips to the icy continent. The group said Aldrin was evacuated on the first available flight out of the Amundsen-Scott South Pole Station to the McMurdo Station on the Antarctic coast under the care of a doctor with the U.S. Antarctic Program. He then was flown to Christchurch, New Zealand, and arrived at about 4:25 a.m. local time Friday (10:25 a.m. Thursday ET), according to the National Science Foundation, which provided the flight for Aldrin.

They have not released much information about his condition, other than saying that Aldrin is in good spirits.

Russia Progress freighter lost during launch

1:39 pm

Due to what appears to be the failure of the third stage of its Soyuz rocket, a Russian Progress freighter bringing supplies to ISS was lost.

The Russian space agency — Roscosmos — confirmed the demise of the Progress MS-04 cargo craft in a statement, saying the automated spaceship was lost as it flew nearly 120 miles (190 kilometers) over the Tuva Republic in Southern Russia. Engineers lost telemetry during the Soyuz rocket’s third stage engine burn, and most of the vehicle’s fragments burned up in the atmosphere, Roscosmos said.

The consequences of this failure are numerous:

  • The cargo failures to ISS have been a continuing problem. Despite significant redundancy, every single cargo freighter has had failures or delays in the past two years.
  • The failure of the Soyuz rocket is a major concern, since this is the rocket that we depend on to bring humans to ISS. Nor is this the first time this year that the third stage had issues. In May the third stage cut off prematurely.
  • This failure, combined with the other quality control problems Russia has experienced in the past few years with the Soyuz capsule and the Proton rocket, adds to the concerns.

It now becomes even more imperative for the U.S. to get its own manned spacecraft capability back.

Russia sets budget for Vostochny through 2019

10:54 am

The Russian government has now allocated a new budget for the next phase of construction at its new spaceport at Vostochny.

“The money has been allocated and specified by Prime Minister Dmitry Medvedev for 2017-2019 within the limits of about 25-30 billion rubles annually, i.e. these funds are not as large as it seemed to us earlier,” the vice-premier said. “These funds have been set aside on the basis of the so-called ‘optimal scenario’ proposed by [State Space Agency] Roscosmos,” Rogozin said.

Essentially, they have lowered the budget and pushed back some of the more costly construction at Vostochny until after 2019. Even with these trims, they also note that the budget will still depend on how the Russian economy does in the coming years.

Airbus to slash more than a 1,000 jobs to cut costs

10:46 am

The competition heats up: In a continuing re-organization to cut costs, Airbus yesterday announced plans to slash 1,164 jobs.

The initiative is part of [Airbus Chief Executive Tom] Enders’s four-year campaign to reshape the business in the wake of the failed attempt in 2012 to merge with BAE Systems PLC, Europe’s largest arms maker. After the deal with BAE faltered on German government opposition, he won shareholder backing for a new structure that reduced French, German and Spanish government involvement in company decision-making. The old structure was a legacy of the founding of the company in 2000 through the combination of European aerospace and defense assets.

Airbus in 2013 moved to merge its defense and space assets and shed some operations not central to its aerospace business.

This approach matches very well with the company’s joint partnership with Safran and their hard-nosed insistence that they own and control Ariane 6. They are pushing to get the government bureaucracy out of their business so that they can work more efficiently and make more money.

New ULA website allows customers to configure their launch

9:58 am

The competition heats up: ULA today announced the creation of a new website, dubbed Rocketbuilder, where customers and the public and configure their own launch rocket.

ULA noted that the tool also provides insight into reliability, schedule assurance and performance, allowing users to make a true value comparison. “The value of a launch is a lot more than its price tag,” said Tory Bruno, ULA president and chief executive officer. “Through our RocketBuilder website, customers are now empowered with pricing information that can be used to make decisions during their spacecraft development process, potentially helping customers keep program costs down. In addition, customers are able to build a rocket based on the needs they input, their spacecraft specifications and mission requirements.”

Users have the flexibility to select a launch date, the satellite’s orbit, rocket configuration and the customized service level needed for the mission. Finally, the site will capture savings in extra revenue or mission life, provide the true total cost of the specific mission requirements, and allow users to begin the contracting process.

This is great news, as it shows that Bruno and ULA are very serious about competing aggressively with SpaceX. For example, Bruno notes that the price of the cheapest Atlas 5 configuration has dropped from $191 million to $109 million in the last few years. And while this price remains significantly more expensive than SpaceX’s $62 million, this new tool should help to drive the costs down more. When ULA learns which configurations sell best, it will then be able to make those configurations cheaper.

The site is also cool. I tried it, and found that it strongly resembles the experience of buying an airplane ticket at sites like Travelocity. You pick various options (payload weight, payload size, orbit, etc) and the site automatically adjusts the rocket’s configuration and the price.

U.S. and China top Russia for most launches in 2016

9:45 pm

The competition heats up: In 2016 it appears that the United States will complete the most rocket launches, at 20, followed by China with 19 and Russia with 18.

For the past two decades Russia has generally been the yearly leader in launches, but recent competition from the U.S. private sector and China’s surging government program, combined with lagging quality control problems and budget shortages in Russia, has had their launch rate decline to third. I also fully expect the U.S. lead to grow in the coming years as a range of low cost new companies come on line.

New Chinese launch company gets its first customer

9:35 pm

The competition heats up: A new Chinese launch company aimed at putting smallsats in orbit for a low price has signed its first customer.

In a statement published by China Daily, Zhang Di, vice president of the China Aerospace Science and Industry Corp. (CASIC) Fourth Academy, said Expace Technology Co. would charge around $10,000 per kilogram of satellite payload, which he said was less than half the prevailing commercial price. Zhang is also chairman of Expace.

CASIC created Expace in early 2016 as China’s second commercial-launch provider after China Great Wall Industry Corp. of Beijing, which has long been China’s showcase export vehicle for launches and commercial satellite contracts. China Great Wall is part of the China Aerospace Science and Technology Corp. (CAST). Zhang said Expace has already signed its first commercial contract, valued at 100 million Chinese yuan, or around $14.5 million, to place three Earth observation satellites into low Earth orbit aboard a Kuaizhou 1 rocket for the government-owned Changguang Satellite Technology Co.

This same company has more than 10 other satellites slated for future launches on Kuaizhou rockets.

The situation here is interesting. This small company is essentially competing against China’s big space company that builds that country’s Long March rockets. It is also aiming to capture some of the market share of the new smallsat industry, specifically targeting international satellite companies that are becoming less and less dependent on the U.S. rocket components that would forbid their use on a Chinese rocket.

Another Google Lunar X-Prize team secures launch contract

9:27 pm

Part Time Scientists, one of the teams competing for the Google Lunar X-Prize, has secured a launch contract through launch rideshare broker Spaceflight Inc.

Their rover will launch as a secondary payload. It is the broker’s job to secure that slot.

PTScientists plans to land its rovers in the moon’s Taurus-Littrow valley, the last place humans set foot on the lunar surface in December 1972, in the hopes of getting a closer look at how the Apollo moon buggy has survived over the past four and a half decades in the extreme temperatures and inhospitable conditions on the moon. “There is a reason we have chosen the Apollo 17 landing site,” said Karsten Becker, PTScientists electronics head, said in a call with reporters on Tuesday. “That is because the Taurus-Littrow valley is geographically very interesting — that is why it was chosen for Apollo 17 — but it is also a very-well documented site. There are many pictures where you can see that it is very flat, and that there are not that many stones laying around.”

The landing site has been chosen to be within reach of the Apollo 17 site, but not so close that it could risk damage to the NASA preservation heritage area. “We want to land 3 to 5 kilometers [2 to 4 miles] away from the [Apollo 17] landing site,” said Becker.

This team is now the fourth X-Prize team to secure a launch contract. All are hoping to launch within the next two years.

ISS Fisheye Fly-Through

6:01 pm

An evening pause: Make sure you watch this full screen. In many ways this video tour of ISS illustrates its magnificence and its failure. It is not an easy thing to build a house in space, and it is clear that we have done it here. At the same time, ISS hardly appears to be a comfortable vessel to live in during travel to other planets. Skylab was much more livable.

Dispute in ESA over Schiaparelli failure

8:54 am

Prior to the release of ESA’s preliminary report on the failure of Schiaparelli, the Italian space agency had claimed the problem was caused by the failure of a Romanian subcontractor to do sufficient simulations and testing.

ESA released the preliminary conclusions after the Italian Space Agency had accused that the decisive tests for the Sciaparelli lander simulations had been entrusted to an organization “which hadn’t enough expertize”. It’s about Arca Space Romanian company, based in Las Cruces, USA, as La Repubblica reported.

In retort, the Arca Space Corporation manager, Dumitru Popescu warned the Italian space agency to be more careful, as they don’t have proves to support their accusations. “They could pay the price. We are at ease that we did all we could do: to run a specific test we should have flown very closely to the Russian base in Sevastopol. Russia has just annexed Crimea and we risked generating a conflict between the Russian Federation and NATO,” the Romanian manager argued.

There is something fishy here, but I’m not sure what. That they didn’t do a test because they feared instigating an international incident with Russia does not seem right. In fact, this whole story suggests that the very management structure of ESA, designed to spread work to as many of its partner nations as possible, is the fundamental source of the problem.

ExoMars’ Trace Gas Orbiter takes first pictures

8:30 am

The European Trace Gas Orbiter (TGO), part of the ExoMars 2016 mission, has successfully transmitted its first images back to Earth.

I have posted a video they have assembled of the first images below the fold. It is quite spectacular. As for TGO’s future misssion:

In the next months, the team will be starting preparations for the prime mission. “The test was very successful but we have identified a couple of things that need to be improved in the onboard software and in the ground post-processing», says Thomas. “It’s an incredibly exciting time.” Eventually, TGO will use “aerobraking” (skimming into the atmosphere) to slow the spacecraft down and enter a roughly circular orbit 400 km above this surface. This process will start in March 2017 and take around 9-12 months. The primary science phase will start around the end of 2017. CaSSIS will then enter nominal operations acquiring 12-20 high resolution stereo and colour images of selected targets per day.

Possible cause of microgravity vision problems identified

10:11 pm

Scientists think they may have located the cause of the vision problems experienced by nearly two-thirds of all astronauts after long missions in weightlessness.

Prof Alperin has been looking at another potential source of the problems – the cerebrospinal fluid (CSF). This helps cushion the brain and spinal cord, and can accommodate the changes when a person moves from a lying to a standing position. “In space the system is confused by the lack of the posture-related pressure changes,” Prof Alperin explained.

The team performed high-resolution MRI scans before and shortly after spaceflights for seven long-duration astronauts. They compared the results with nine astronauts who flew into orbit for short stints on the space shuttle. The results showed that long-duration astronauts had significantly greater post-flight increases in the volume of CSF within the bony cavity of the skull that holds the eye, and also in the volume of CSF in the cavities of the brain where the fluid is produced.

The sample size is small, and the study has not yet been peer reviewed, so these results must still be taken with some skepticism.

Software error caused Schiaparelli crash

12:52 am

A new ESA report says that the ExoMars 2016 Schiaparelli lander failed because its navigation system thought the lander was on the ground when it was still more than two miles from the surface.

Europe’s Schiaparelli Mars lander crashed last month after a sensor failure caused it to cast away its parachute and turn off braking thrusters more than two miles (3.7 km) above the surface of the planet, as if it had already landed, a report released on Wednesday said.

Figuring out what caused this failure will be helpful for the design of the ExoMars 2020 rover, but the failure here is likely going to make it more difficult for Europe to raise the money needed for that next mission, including a 400 million euro cost overrun.

Rocket Lab delays first rocket test flights

12:42 am

Rocket Lab has revealed that it will not conduct its first test flight of its new Electron rocket before the end of the year.

Rocket Lab originally scheduled road closures for test launches between November 17 and December 24. The company is now planning to conduct the first test flight early next year. Rocket Lab media spokeswoman Catherine Moreau-Hammond said the team had worked tirelessly this year, and with the holidays fast approaching they felt it best to allow everyone a decent break. Ms Moreau-Hammond said this would also alleviate some pressure on Mahia, which experiences a considerable population spike through the Christmas holidays.

This is a new company, a new rocket, a new launchpad, in a new country inexperienced in rocket launches. It is therefore not surprising that things have been delayed.

SpaceX wins NASA satellite launch contract

6:28 pm

The competition heats up: NASA has awarded SpaceX the contract to launch its Earth science satellite, Surface Water and Ocean Topography (SWOT).

This sentence from the press release is puzzling:

The total cost for NASA to launch SWOT is approximately $112 million, which includes the launch service; spacecraft processing; payload integration; and tracking, data and telemetry support.

Since SpaceX touts a launch price for its Falcon 9 rocket as $62 million, I wonder why this launch will cost NASA almost twice as much. Was there so little competition in the bidding that SpaceX could bid higher and thus get more money? Or is NASA so disinterested in saving money that it left itself open to overpaying for something that everyone else gets for far else?

An update on the Bigelow inflatable module on ISS

9:12 am

NASA has released an update on the privately built inflatable BEAM module that is presently attached to ISS and is under-going two years of testing.

NASA and Bigelow Aerospace are pleased to report that, overall, BEAM is operating as expected and continues to produce valuable data. Structural engineers at NASA JSC confirmed that BEAM deployment loads upon the space station were very small, and continue to analyze the module’s structural data for comparison with ground tests and models. Researchers at NASA’s Langley Research Center in Hampton, Virginia, have found no evidence of large debris impacts in the DIDS data to date—good news for any spacecraft. And radiation researchers at JSC have found that the dosage due to Galactic Cosmic Rays in BEAM is similar to other space station modules, and continue to analyze local “trapped” radiation particles, particularly from the South Atlantic Anomaly, to help determine additional shielding requirements for long-duration exploration missions.

None of this is a surprise. It seems to me that this testing program is a bit overdone, since NASA never did anything like this in orbit for its own modules. What I think is really happening is that the two-year test of Bigelow’s module was required politically within NASA because there were too many people there opposed to using a privately-built module. I also suspect that NASA got further pressure from the contractors, such as Boeing, who had previously owned this business, and did not want the competition from Bigelow. Thus, despite the fact that Bigelow has already launched two test modules of its own and proved the viability of its designs, it was forced by NASA to do an additional test under NASA’s supervision in order to squelch this opposition.

Russia postpones Proton launch again

9:03 am

Originally scheduled for October, International Launch Services (ILS), the Russian company that manages its commercial launches, has once again postponed the next Proton rocket launch.

“The new launch date is December 2016,” the website says. The reasons for the postponement have not yet been announced.

As reported earlier, Russia’s space corporation Roscosmos had rescheduled the launch from October 10 to November 23. It was initially scheduled for late June, then postponed to August 29 and then to October 10.

More significantly, there have been no Proton launches since a June 9 launch were the second stage of the rocket inexplicably shut down prematurely. The Russians have been conducting an investigation, but have released absolutely no information about what they have found

Atlas 5 launches NOAA weather satellite

10:53 pm

Successfully completing its second launch in 8 days, ULA’s Atlas 5 rocket put a new NOAA weather satellite in orbit on Saturday.

NOAA is giving this new satellite a big PR push, claiming it will revolutionize weather monitoring and forecasting. While the satellite might be state of the art, it is also was very expensive, costing $1 billion. I strongly suspect that the same thing could have been built far cheaper, and quicker, if left to the private sector.

UAE sheikh okays next phase in Mars mission

10:48 pm

The competition heats up: The Vice President and Prime Minister of the United Arab Emirates and the ruler of Dubai, Sheikh Mohammed bin Rashid Al Maktoum, has approved the start of construction of the prototypes for the UAE’s Mars Mission, dubbed Hope.

Sheikh Mohammed gave the greenlight to start manufacturing the probe’s prototypes, the Arab world’s first Mars probe. The project places the UAE with the nine countries that aim to explore Mars. His Highness said: “UAE ambitions is to explore the outer space. We are investing in our national cadres to lead this project and contribute in expanding our knowledge about Mars. Hope Probe is a qualitative leap for UAE’s scientific efforts, it the first contribution for the Arab world in this regard”.

Sheikh Mohammed’s remarks came while visiting the Mohammed Bin Rashid Space Centre (MBRSC) to open the second phase of the UAE satellite manufacturing and assembly complex, a multitasking facility capable of handling several space projects at a time.

It will be very interesting to see how this top-down mission proceeds, as it is being pushed heavily by the sheikh in a country with almost no experience in building such things.

Ceres' crated surface

Cool image time! The picture on the right, reduced to show here, was taken on October 17 and was the tenth image taken by Dawn in its new extended mission in orbit around Ceres.

This image of the limb of dwarf planet Ceres shows a section of the northern hemisphere. A shadowy portion of Occator Crater can be seen at the lower right — its bright “spot” areas are outside of the frame of view. Part of Kaikara Crater (45 miles, 72 kilometers in diameter) is visible at top left.

The image was taken from 920 miles away and has a resolution of about 460 feet per pixel.

Boeing files FCC application for 3,000 satellite constellation

10:10 am

The competition heats up: Boeing this week submitted its second application to the FCC for its own 3,000 satellite constellation to provide “a wide range of advanced communications and Internet-based services.”

The second application this week specifically requested permission to launch the first 60 satellites. The whole plan is comparable to the one that SpaceX submitted earlier this week, and puts these two companies in direct competition. If both plans are launched, it will mean that more than 6,000 satellites will need launch services to gain orbit, which also means the launch business could get very busy in the coming years.
