China Announces Launch Time, Crew, for Tomorrow's Space Station Mission

China Announces Launch Time, Crew, for Tomorrow's Space Station Mission

China today announced the liftoff time for the Shenzhou-9 spacecraft launch tomorrow, June 16, 2012.  Shenzhou-9 will carry the first Chinese space station crew to the Tiangong-1 space station, already in orbit. The crew includes the first Chinese woman astronaut.

The launch will take place at 18:37 Beijing time, which is 10:37 GMT or 6:37 am Eastern Daylight Time.  The crew is Jing Haipeng, Liu Wang and Liu Yang.   Liu Yang is the first Chinese woman to be launched into space.

The crew was introduced to the public at a Chinese press conference.  The video is on CCTV.  It is in Chinese with simultaneous translation into English. 

Jing is the commander of the mission.   He flew on the Shenzhou 7 mission in 2007.  Liu Wang, 42, will be in charge of the manual docking.  Liu Yang, born in 1978, will be in charge of medical experiments.

NASA Downplays Threat of Asteroid 2011 AG5 Impact in 2040

NASA Downplays Threat of Asteroid 2011 AG5 Impact in 2040

NASA released a workshop report today that downplays the risk to Earth of Asteroid 2011 AG5, saying that it “will fly safely past and not impact Earth in 2040.”   Asteroid 2011 AG5 is one of a subset of Near Earth Objects (NEOs) classified as Potentially Hazardous Asteroids (PHAs).

The agency acknowledges, however, that more observations are needed in the years ahead to be doubly sure that analysis is correct.  A key event will occur — or not — in February 2023 when the asteroid is 1.1 million miles from Earth.   If it passes through a very small “keyhole” in space at that time, Earth’s gravity could be just enough to modify its trajectory such that an impact with Earth might be possible on February 5, 2040. 

The keyhole is 227 miles wide.   Lindley Johnson, program executive for NASA’s Near Earth Object (NEO) observation program, said: “Given our current understanding of this asteroid’s orbit, there is only a very remote chance of this keyhole passage even occurring.”

Today’s press release provides a link to a JPL website where four related documents are posted, including a “consensus summary” of the May 29, 2012 workshop.   The links to the four documents are a little hard to find so are provided here:

The one page consensus summary of the workshop does not list the participants.  Shown as bullet-points, it states that there is only a 0.2 percent chance of the asteroid passing through the keyhole in 2023, and also only a 0.2 percent change of it impacting Earth in 2040.

The 140-meter diameter asteroid was discovered in January 2011 and is currently located in the daytime sky and cannot be observed with Earth-based telescopes.  Observations can be made in the fall of 2013 and again in 2015-2020.  Data from those observations will allow scientists to better predict its path.

Should the unlikely occur and it turns out the asteroid is on a collision course with Earth after all, the workshop concluded that “numerous viable deflection mission options are available.”   For example, “an impactor spacecraft could be an effective means.”  If that approach is chosen, “[i]t is desirable to also have a rendezvous spacecraft on station at the asteroid at least a few months” in advance and it could be “equipped with a gravity tractor” as a backup.

Preparations on Track for Launch of First Chinese Space Station Crew, Manual Docking Planned

Preparations on Track for Launch of First Chinese Space Station Crew, Manual Docking Planned

China’s preparations for the launch of its first space station crew — including its first woman astronaut — remain on track for Saturday, weather permitting.   China’s Xinhua news service reveals that the crew will perform a manual rather than automated docking with the Tiangong-1 space station.

China’s CCTV news (in English) reports today that the Long March IIF rocket is being fueled at the Jiuquan launch center in the Gobi desert.  Water and food have been loaded into the Shenzhou-9 spacecraft for the three-person crew.  CCTV confirms again today that the crew will include China’s first woman astronaut.  

China has not announced the launch time for Shenzhou-9, but independent analysts calculate it at 10:39 or 10:41 GMT (6:39 am or 6:41 am Eastern Daylight Time).  Dragon-in-space, a website that focuses on China’s space program but states that it is not affiliated with any government agency or private organization, said that the crew most likely will be Jing Hai-peng, Liu Wang and Liu Yang, and the backup crew is Nie Hai-sheng, Chen Quan, and Wang Ya-ping.  Previously it had reported that the Nie crew was primary, but said on June 12 that the Jing crew is primary.  The Chinese government has said repeatedly that the final crew will not be selected until Friday.  This photograph from the Dragon-in-Space website reportedly shows both crews, but does not identify the individuals.

CCTV and other Chinese media sources note that this is the first of their human spaceflight launches to take place in the summer.  CCTV reports that the heat at the launch site adds to the problem of “controlling the termperatures of the spaceship and the escape tower.”  Xinhua (in English) reports that the propellant must be cooled to 15 degrees Celsius to prevent it from vaporizing in the high heat.   Other seasons of the year pose their own problems.   Xinhua reveals that for the December 30, 2002 launch of the Shenzhou-4 spacecraft — a test flight that did not carry a crew — cotton quilts were used to keep the rocket warm as temperatures fell to minus 29 degrees Celsius.  

Sandstorms are another problem and Xinhua says “strong wind and sand” blew through the launch site on Wednesday, but the forecast for Friday and Saturday is for “relatively stable” weather.

The sound of the wind complicated a live video report by CCTV reporter Wang Yizhi today who is at Jiuquan.  She said that the wind cannot be more than 15 meters per second at the time of launch and it was “well above” that during her report  She also disputed other media reports that the final crew had been selected and emphasized that the decision would be made on Friday.

If weather delays Saturday’s launch, Bob Christy at zarya.info calculates alternative launch dates as June 18, 20, 22 or 24.

Xinhua says that the Chinese crew will peform a manual rather than automated docking with the Tiangong-1 space station.   Automated tests were conducted last year using the Shenzhou-8 spacecraft, but they apparently plan to use a manual docking this time.

Tiangong-1, China’s first space station, was launch in September 2011.   Shenzhou-8 rendezvoused and docked with it twice in November.   Neither spacecraft had a crew.

 

China Confirms June 16 for First Space Station Crew Launch, Including First Woman Astronaut

China Confirms June 16 for First Space Station Crew Launch, Including First Woman Astronaut

China’s CCTV television (in English) confirmed today that China’s first space station crew will be launched on June 16, 2012 and will include China’s first woman astronaut.  

Previously China said only that the launch would take place in mid-June, but June 16 had been identified as a likely date by independent analysts, with launch around 10:30 am GMT (6:30 am EDT).

The announcement came after a successful four-and-a-half hour dress rehearsal of the Shenzhou-9 spacecraft and Long March IIF rocket at the Jiuquan launch site.  One brief CCTV video report shows three space-suited astronauts boarding the spacecraft while the announcer states that the crew includes a female. 

A longer second CCTV video report features a woman reporter who summarizes the test and the upcoming mission.  She adds that the crew will spend 10-12 days in space and the female astronaut will perform scientific experiments while the men “perform the flying as well as conducting the … rendezvous and docking part” of the mission.

The final crew will not be chosen until Friday, the reporter said, but a woman will be included.  The astronauts who participated in today’s test are “promising candidates” and will remain in quarantine for the remaining days before launch, she said. 

Chinese astronauts are usually referred to as taikonauts in the West, but the CCTV report refers to them as “astronauts.”

China’s Tiangong-1 space station was launched last fall.  The automated Shenzhou-8 spacecraft conducted rendezvous and docking operations with it in November.

China Readies to Launch Space Station Crew-update

China Readies to Launch Space Station Crew-update

UPDATE:  Dragon-in-Space, a website devoted to China’s space program that it says is not affiliated with any government agencies or private organizations, reports that the Shenzhou 9 launch will take place at 10:41 GMT on June 16 and it will carry a female taikonaut. Wang Ya-ping. Bob Christy has updated his website to also indicate that June 16 is the first likely launch date, with 10:39 GMT as the launch time.  Eastern Daylight Time (EDT) is four hours behind GMT, so that would make it 6:41 am or 6:39 am EDT.  These are not official Chinese government launch dates or times, however.

ORIGINAL STORY: China still has not put an official date on it, but Xinhua reported yesterday that the first Chinese space station crew will be launched in “mid-June” as the Shenzhou-9 spacecraft and its rocket were moved to the launch pad.

China launched its first space station, Tiangong-1 (Heavenly Palace), last September.  An automated spacecraft, Shenzhou 8, tested rendezvous and docking operations with it twice in November.   China said at the time it planned to launch two more missions to Tiangong-1 and at least one would involve a crew and that crew likely would include China’s first female taikonaut.

China indicated months ago that the launch would be this summer, but has not been specific about the date.  Bob Christy, an amatuer space observer in the United Kingdom, initially calculated June 17 as a likely launch date based on Tiangong-1’s orbital maneuvers.  He has refined his analysis and now assesses that the launch could take place on alternate days beginning June 14.  His website, zarya.info, lists the likely launch times on June 14, 16, 18, 20, 22, and 24.

The Shenzhou-9 spacecraft and its Long March 2F rocket were moved to the launch platform at the Jiuquan Satellite Launch Center yesterday according to Xinhua.  China still did not commit to launching a woman on the mission, insisting that the decision on crew members will not be made until closer to launch.

One of the three crew members apparently will not enter the space station, but remain in Shenzhou 9.   Xinhua quoted a spokesman as having said in February that “[o]ne of the three Shenzhou-9 crew members will not board the Tiangong-1 space module lab, but will remain inside the spacecraft as a precautionary measure in case of an emergency.”

Tiangong-1 is quite modest (8.5 metric tons) compared to the International Space Station (about 400 metric tons), but nevertheless occupying a space station will be a significant achievement for China if all goes well.   As first space stations go, Tiangong-1 is just less than half the mass of the world’s first space station, the Soviet Union’s Salyut 1.  Launched in 1971, it had a mass of about 18.6 metric tons.  The first U.S. space station, Skylab, launched in 1973, had a mass of about 77 metric tons.

DOD Tempers Language about China's Space Program, Warns it Faces Challenges

DOD Tempers Language about China's Space Program, Warns it Faces Challenges

The U.S. Department of Defense (DOD) told Congress last month that while China’s space program overall continues to expand, individual programs “are facing some challenges in systems reliability.”  The increasing pace of launches “also may be taking its toll,” it adds.

DOD is required by Congress to report every year on military and security developments in China.  The report is commonly referred to as the “China military power” report, but the official title of the 2012 edition is Military and Security Developments Involving the People’s Republic of China.  The report is submitted in both classified and unclassified forms; the public version upon which this article is based is the unclassified one (obviously).

This year’s report is noticeably shorter than last year’s, 52 pages compared to 94, with commensurately less detail about China’s space activities.  China’s 2011 launch of an experimental space station, Tiangong-1, is only briefly mentioned.   At a May 18 press conference, David Helvey, Acting Deputy Assistant Secretary of Defense (East Asia), said DOD “streamlined and consolidated the report, in keeping with DOD-wide guidance for how we’re handling reports to Congress.”

Apart from the lack of detail, the two biggest changes are the cautionary statement DOD makes about challenges China’s space program is facing and the fewer types of counterspace capabilities DOD says China is developing.

The 2011 and 2012 reports are similar in that they both say China is expanding “its space-based surveillance, reconnaissance, navigation, meteorological, and communication satellite constellations,”  and “continues to develop the Long March V  rocket,” which “will more than double the size” of payloads China can launch.

China hopes to launch its first Long March V (or Long March 5), a Delta IV-class rocket, in 2014 from a new launch site on Hainan Island.   It is designed to launch 25 tons to low Earth orbit or 14 tons to geosynchronous orbit.   

Like last year, DOD describes China’s development of counterspace capabilities as “multidimensional,” but the list of those capabilities is shorter this year.   Both reports list the direct-ascent antisatellite (ASAT) weapon China tested in 2007 that created more than 3,000 pieces of space debris, engendering international condemnation.  The 2012 edition succinctly adds “jamming, laser, microwave, and cyber weapons.”  In the 2011 version, DOD said China was “developing other kinetic and directed-energy (e.g. lasers, high-powered microwave, and particle beam weapons) technologies for ASAT weapons. Foreign and indigenous systems give China the capability to jam common satellite communications bands and GPS receivers.  China’s nuclear arsenal has long provided Beijing with an inherent ASAT capability, although a nuclear explosion in space would also damage China’s own space assets, along with whomever it was trying to target.”

This year’s report states that over the past two years China has conducted “increasingly complex close proximity operations between satellites while offering little in the way of transparency or explanation,” but does not mention the rendezvous and docking operations the automated Shenzhou 8 spacecraft conducted with Tiangong-1 last November in that context.   While the 2011 report did not discuss proximity operations, it drew a connection between China’s “manned and lunar” programs and counterspace capabilities.   It asserted that China cited requirements of its “manned and lunar space programs” as reasons for improving its abilities to “track and identify” satellites, capabilities that also are “a prerequisite for effective, precise counterspace operations.”   Also, DOD’s statement in the 2011 report that China plans a permanent space station by 2020 and landing a human on the Moon by 2030 is not repeated.

As for the challenges DOD says China is facing, the report reveals that communications satellites using China’s DFH-4 platform “have experienced failures leading to reduced lifespan or loss of the satellite.”  It also mentions the failure of a Chinese Long March 2C in August 2011.  That was the third satellite launch in seven days for China, and DOD comments that “The recent surge in the number of China’s space launches also may be taking its toll.”  

China conducted 18 successful space launches in 2011, a new record for China, and more than any other country except Russia.

At the May 18 press conference, Helvey said that DOD sees areas where the United States and China can work together on common threats, such as piracy, and wants to have a conversation with China about that, but is also concerned about Chinese activities that would make cooperation difficult, such as its investments in counterspace capabilities.  He cited the Strategic Security Dialogue as a “platform” for such discussions.

SWF: Mis-communicating about Asteroid Threat is a Threat Itself

SWF: Mis-communicating about Asteroid Threat is a Threat Itself

The Secure World Foundation (SWF) released a report yesterday warning that the dangers of mis-communicating about the threat from an asteroid can be as much a threat as the asteroid itself.

SWF and the Association of Space Explorers (ASE) held a workshop in November 2011 about the need to communicate effectively with the public about risks posed by asteroids.  The workshop was held to support the United Nations Committee on Peaceful Uses of Outer Space (COPUOUS) Action Team-14 (AT-14) that focuses on Near Earth Objects (NEOs).  AT-14 is deliberating over the potential composition of an Information, Analysis and Warning Network (IAWN) that includes developing international procedures to respond to a NEO threat according to the workshop report.

SWF Executive Director Michael Simpson said in a press statement that while attention is usually focused on the damage an asteroid impact with Earth could cause, this report focuses “on how to prevent the even greater damage we could cause ourselves by mis-communicating or failing to work together on a common response to the threat.”  Ray Williamson, SWF Senior Advisor and former Executive Director, said the report “emphasizes how important clear, effective, and accurate assessments” of the threat would be “to the ultimate goal of protecting human life and property.”

The report issued a “call to action” with the following elements:

  • The development of an effective NEO communication plan;
  • A coordinated program of education targeting general public, policy makers, students and media;
  • Skilled communicators supported by risk analysts, planners, scientists, psychologists, emergency management experts and other functional experts; and
  • Access to research data and real-time NEO information.

 

 

NRO Gifts NASA Two Leftover Space Telescopes, Euclid to Cost NASA $40-50 Million, GEMS Not Confirmed

NRO Gifts NASA Two Leftover Space Telescopes, Euclid to Cost NASA $40-50 Million, GEMS Not Confirmed

NASA revealed today that the National Reconnaissance Office (NRO) gave it two leftover space telescopes.  NASA is looking at using one of them and must determine how much it would cost to build, launch and operate a spacecraft that would incorporate it.  NASA also must decide what other instruments may be needed to achieve the scientific objectives in the most recent National Research Council (NRC) decadal survey for astronomy and astrophysics.

NASA astrophysics division director Paul Hertz told a meeting of the NRC’s Committee on Astronomy and Astrophysics (CAA) about the gift this morning.   His short talk was followed by a more lengthy explanation by Dr. Alan Dressler of the Observatories of the Carnegie Institution.  Dressler chaired the panel of the NRC’s 2010 astronomy and astrophysics decadal survey, New Worlds, New Horizons (NWNH), that recommended a mission called the Wide-Field InfraRed Survey Telescope (WFIRST) as the top priority for a large space mission for the next decade of space-based astrophysics research. 

WFIRST is a multi-purpose telescope that would study dark energy, search for exoplanets, and survey the universe in the infrared wavelengths.  Budget constraints exacerbated by significant overruns on the James Webb Space Telescope (JWST) have pushed WFIRST well into the 2020s.  

NRO builds and operates the nation’s spy satellites.  NASA officials said today that NRO contacted the agency over a year ago to see if NASA wanted the two 2.4 meter diameter space-qualified telescopes because they were no longer needed.  NASA said yes and the telescopes are now its property.  They have been declassified, but are still subject to export control restrictions.  Although NASA inherited two telescopes, it is only talking about using one, at least for now.   Hertz said they are calling it the NEW mission — NWNH Enabling Wide-field — with the idea that it could enable the science envisioned in New Worlds, New Horizons for a wide-field infrared telescope.

Dressler was one of a small group of scientists asked by NASA to review the potential of achieving the science objectives of WFIRST by using one of the NRO telescopes.  The study group also included CAA co-chair David Spergel.  WFIRST was designed as a 1.5 meter diameter telescope, while the NRO telescopes are 2.4 meters.  Dressler said that NASA’s Goddard Space Flight Center and Jet Propulsion Laboratory have known about the telescopes for some time and several mission designs have emerged.   For him, the starting point would be to use the mirrors as they currently exist, although he expressed a strong preference for adding a coronograph to the mission.  He said that his preliminary answer is that an NRO-based mission could accomplish the WFIRST science goals perhaps better than WFIRST itself.   While stressing that more work is needed, he expressed his personal view that “the potential exists to have greater capability for the WFIRST science, enable additional scientific opportunities, match or reduce cost, and improve schedule, and that this possibility should be pursued as vigorously as possible by the astronomical community.”

The NRC conducts Decadal Surveys for each of NASA’s space and earth science disciplines.  Performed every 10 years, they look out to the next 10 years (hence the term decadal) to determine the most compelling scientific questions and what missions are needed to answer them within a budget envelope NASA provides.  Because they represent a consensus of the relevant discipline, they are closely followed by NASA and highly respected by Congress.  The NRC has standing committees that keep track of what NASA (and other agencies as appropriate) are doing to achieve the Decadal Survey’s recommendations.   CAA oversees compliance with the astronomy and astrophysics Decadal Survey, which also includes recommendations to the National Science Foundation and Department of Energy’s Office of Science.

The CAA’s response to the news was rather muted.  The reaction was surprisingly flat for a community that received a fairly valuable gift.  At a media teleconference later in the day, NASA’s Michael Moore, deputy astrophysics division director, estimated that about $250 million in mission costs could be avoided by using one of the NRO telescopes.  He added that the telescopes cost about $75,000-$100,000 to store at the manfacturer’s (ITT Excelis) facilities in Rochester, NY.   In response to a question at the media teleconference, Hertz said he thought CAA members were “excited at the possibilities,” while Dressler acknowledged that some people “need to have a lot more time” to consider the situation.  This is a “sharp right turn,” he added, compared to what was recommended in NWNH.

Some CAA members wanted to know if NASA should now reconsider its participation in the European Space Agency’s (ESA’s) Euclid mission, apparently on the assumption that with the gift of the telescopes NASA might be able to move out more quickly with a WFIRST-like mission.  Euclid will study dark energy, which also is one of the goals of the WFIRST mission.   Hertz said that NASA was already committed to its participation in Euclid.   In fact, he informed the committee that the cost of NASA’s contribution to Euclid will be $40-50 million instead of $20 million as recommended by another NRC committee.   NASA agreed to provide near infra-red detectors for Euclid, but ESA convinced NASA that it also needed the associated electronics, which increased the cost to NASA.

Hertz also emphasized repeatedly that NASA currently does not have the money to build, launch and operate a spacecraft that would use one of the NRO telescopes.   The telescope may be free, but NASA must pay for everything else.  Launch of JWST is an agency priority and until that happens, the budget for astrophysics at NASA is highly constrained.   Hertz also stressed that obtaining permission from the White House and Congress for NASA to begin another large mission like JWST should not be taken for granted.   Until NASA demonstrates that it can complete JWST on its new baseline budget and schedule, he does not expect policy-makers to have confidence that NASA can perform on time and cost.

Separately, Hertz told the committee that NASA had “not confirmed” the Gravity and Extreme Magnetism (GEMS) Small Explorer mission because it experienced unacceptable cost increases during its early formulation stage.  NASA missions must pass through certain “gates,” one of which is a confirmation review.  GEMS did not pass that gate.  NASA will reallocate those funds for other Explorer missions.

Editor’s Note:  Although the announcement about the NRO telescopes came as a surprise to many, at least two news outlets – the New York Times and Washington Post — clearly were told about it earlier.   Each published stories including quotes from people who were not at the CAA meeting very shortly after Hertz spoke.  NASA also did not inform all journalists about the media teleconference.  SpacePolicyOnline.com thanks NASAWatch for publicizing it.

Christy: Shenzhou 9 Launch to Chinese Space Station Possible June 17

Christy: Shenzhou 9 Launch to Chinese Space Station Possible June 17

Bob Christy of Zarya.info anticipates that China’s next launch to its Tiangong 1 space station may occur on June 17.   China launched Tiangong 1 last year and the unoccupied Shenzhou-8 spacecraft conducted automated rendezvous and docking tests with it in November.  China said at the time that two more Shenzhou spacecraft would visit the space station over the next two years.  In March, China’s Xinhua news agency said that the next spacecraft, Shenzhou 9, would carry a three-person crew, possibly including China’s first female taikonaut.

Christy’s analysis of orbital maneuvers by Tiangong 1 leads him to conclude that June 17 is the most likely, but not certain, date for the Shenzhou 9 launch.  Writing in Space Daily today, he says that a launch window opens on June 17 and based on the fact that China recently lowered Tiangong 1’s apogee, he concludes that “a late morning launch (UTC) will allow Shenzhou 9 and its crew of three to make rendezvous with Tiangong 1.”

Tiangong-1 (Heavenly Palace) was launched in September 2011.  It is very small compared to the International Space Station (ISS) — 8.5 metric tons (19,000 pounds) compared to about 400 metric tons (885,600 pounds) — but nonetheless is a space station and placing a crew aboard would be a significant step in China’s human spaceflight achievements.  

Shenzhou 8, launched October 31 Eastern Daylight Time (November 1 in China) made two automated dockings in November and returned to Earth on November 17. 

China’s Xinhua news agency reported on May 11 that Shenzhou 9’s launch vehicle had been moved to the pad, but did not specify a launch date, saying only that it would take place between June and August with the goal of completing “a manned rendezvous and docking mission.”   Xinhua said in March that an initial crew selection had been completed and women were included in the roster, but the final choice of the three-person crew would not take place until much closer to launch.
