NASA has just released an amazing new view of the mysterious south pole of Vesta that offers an oblique perspective view of the central mountain peak which is three times as high as Mt Everest. This topographic view , shown above,is completely unique to viewers from Earth and is provided courtesy of NASA’s exotic Dawn Asteroid Orbiter – newly arrived in July 2011.
The mountain peak rises about 15 miles (22 km) above the average height of the surrounding pockmarked terrain at Vesta’s south polar region – formally named Rheasilvia – and is located in the foreground, left side of the new image. A portion of the crater rim with a rather steep slope – known as a scarp – is seen at the right and may show evidence of Vestan landslides.
This oblique image derived from the on board Framing Camera was created from a shape model of the 530 km diameter asteroid. It has been flattened to remove the curvature of Vesta and has a vertical scale adjusted to 1.5 times that of the horizontal scale.
The origin of Vesta’s south polar region is hotly debated among the mission’s science team who will reveal their current theories at a briefing set for October 12 – watch for my upcoming report.
Dawn will remain in orbit at Vesta for 1 year until July 2012 and then fire up its revolutionary ion propulsion system to depart for Ceres, the largest Asteroid in the main belt between Mars and Jupiter.
Assembly of the powerful Atlas V booster that will rocket NASA’s Curiosity Mars Science Laboratory rover to Mars is nearly complete. The Atlas V is taking shape inside the Vertical Integration Facility at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.
The rocket is built by United Launch Alliance under contract to NASA as part of NASA’s Launch Services Program to loft science satellites on expendable rockets.
The Atlas V configuration for Curiosity is similar to the one used for Juno except that it employs one less solid rocket motor in a designation known as Atlas 541.
4 indicates a total of four solid rocket motors are attached to the base of the first stage vs. five solids for Juno. 5 indicates a five meter diameter payload fairing. 1 indicates use of a single engine Centaur upper stage.
Blastoff of Curiosity remains on schedule for Nov. 25, 2011, the day after the Thanksgiving holiday in the U.S. The launch window for a favorable orbital alignment to Mars remains open until Dec. 18 after which the mission would face a 26 month delay at a cost likely to be in the hundreds of millions of dollars.
Curiosity is set to touchdown on Mars at Gale Crater between August 6 & August 20, 2012. The compact car sized rover is equipped with 10 science instruments that will search for signs of habitats that could potentially support martian microbial life, past or present if it ever existed.
Meanwhile NASA’s Opportunity Mars rover is nearing 8 continuous years of Exploration and Discovery around the Meridiani Planum region of the Red Planet.
With just over 6 weeks to go until the liftoff of Curiosity – NASA’s next Mars rover – prelaunch processing at the Kennedy Space Center (KSC) in Florida is rapidly entering the home stretch. Technicians placed the folded rover inside the complete aeroshell to match the Martian entry configuration components together and conduct preflight testing of the integrated assembly at the Payload Hazardous Servicing Facility at KSC. The aeroshell is comprised of the heat shield and back shell and encapsulates Curiosity during the long voyage to Mars.
The job of the aeroshell is to protect the Curiosity Mars Science Laboratory (MSL) from the intense heat of several thousand degrees F(C) generated by friction as the delicate assemblage smashes into the Martian atmosphere during the terrifying entry and descent to the surface.
The rover itself has been mated to the back shell powered descent vehicle, known as the PDV or sky crane. The rocket powered descent stage (PDV) is designed to maneuver through the Martian atmosphere, slow the descent and safely set Curiosity down onto the surface at a precise location inside the chosen landing site of Gale Crater.
Technicians still have several more weeks of hardware testing and planetary protection checks ahead before NASA’s minivan sized Martian robot is encapsulated inside the aeroshell for the final time.
Another major task still to be completed is mating the aeroshell to the cruise stage and then fueling of the cruise stage, which guides MSL from the Earth to Mars, according to Guy Webster, press spokesman for NASA’s Jet Propulsion Laboratory which manages the MSL project for NASA.
The launch of the $2.5 Billion Curiosity rover atop an Atlas V rocket is slated for Nov. 25, the day after Thanksgiving, and the launch window extends until Dec. 18. Arrival at Gale crater is set for August 2012.
Curiosity is by far the most scientifically advanced surface robotic rover ever sent beyond Earth and will search for environmental conditions that could have been favorable to support Martian microbial life forms if they ever existed in the past or present.
The Guardian newspaper in England is reporting that China’s state run television, CCTV, and China’s space agency released a video animation of the just launched Tiangong 1 miniature space station showing extensive footage of rendezvous and docking maneuvers in Earth orbit that is inexplicably set to the tune of “America the Beautiful”, a patriotic hymn that many American’s regard as a second, unofficial national anthem. Watch the YouTube video above and decide yourself.
The Guardian writes; “While China’s leaders were celebrating the triumphant launch of Tiangong-1 space lab on Thursday (Sept 29) , viewers of state television footage [CCTV] were treated to a bizarre choice of soundtrack: America the Beautiful”.
Selecting “America the Beautiful’ for the Tiangong-1 (Heavenly Palace 1) launch sound track seems rather questionable, says the Guardian, and it’s hard to tell if this was choice was intentional or an error by the propaganda department
“Is this the work of an idealist seeking to usher in a new era of trans-Pacific co-operation, a nationalist who wants to colonise American culture as well as outer space, or simply a propaganda gaffe?” – wrote the Guardian
A CCTV official quoted by the Guardian could not offer any clarification.
“I don’t know how to answer your question,” Chen Zhansheng of the CCTV propaganda department said. “I cannot help you.”
[/caption]
The CCTV website states that the animation was provided by the Jiuquan Satellite Launch Center and provides a detailed description. Since the Guardian’s story, the animation has been deleted by CCTV.
The animation itself begins with a simulated launch of Tiangong-1 aboard the Long March 2F rocket and then shows the upcoming rendezvous and docking sequence with the Shenzhou-8 unmanned capsule that is set to launch in early November
Two days after blastoff of Shenzhou-8, it will complete China’s first rendezvous and docking in space. After about 12 days, the two spacecraft are due to uncouple.
China will then attempt another docking to gain more practice ahead of the launch of two manned Shenzhou capsules scheduled for 2012 (Shenzhou-9 and 10) with crews of two or three Chinese astronauts, one of whom may be a woman.
Check this action packed alternate version I found, in Chinese, which is set to different music and with even more extensive animation of the Tiangong 1/Shenzhou-8 joint mission.
One thing absolutely clear is that China is aggressively pushing forward with its manned space program, while the US space program retrenches due to continual budget cutbacks.
China plans to orbit a 60 ton, 3 module manned space station by 2020, about the time when the lifetime of the ISS may be coming to an end, unless the international partners agree to fund an extension of its orbital research activities.
The Chinese space station would be about the size of America’s first space station – Skylab.
In the meantime, officials at the Beijing Aerospace Flight Control Center report that they continue adjusting the orbit of the 10 meter long Tiangong-1 space lab module.
Ed Weiler, NASA’s Science leader in charge of the robotic missions that continually produce scientific breakthroughs that amaze all humanity and longtime Chief Scientist on the Hubble Space Telescope that has completely revolutionized our understanding of humanities place in the Universe, retired today (Sept. 30) from NASA after a distinguished career spanning almost 33 years.
Weiler is departing NASA during what has been dubbed the “Year of Space Science”- the best year ever for NASA Space Science research. The two most recent successes are the launch of JUNO to Jupiter and the twin GRAIL probes to the Moon. Blastoff of the Curiosity Mars Science Laboratory rover is slated for late November 2011.
Weiler’s official title is associate administrator of NASA’s Science Mission Directorate (SMD) at agency Headquarters in Washington, DC. In that capacity he was responsible for overseeing NASA’s science and research programs in Earth science, heliophysics, planetary science and astrophysics.
Weiler was appointed to lead SMD in 2008. He holds this position now for the second time after serving in between as Director of NASA Goddard Spaceflight Center in Greenbelt, Maryland from 2004 to 2008. His earlier stint as associate administrator lasted from 1998 to 2004 for what was then called the Space Science Enterprise.
Probably the job he loved best was as Chief Scientist of the Hubble Space Telescope from 1979 to 1998, until he was promoted to the top rung of NASA management.
I was very lucky to meet and chat with Ed Weiler while I was covering the final space shuttle flight – STS-125 – to repair and upgrade Hubble. STS 125 blasted off in May 2009 and accomplished every single objective to catapult Hubble to the apex of its capabilities.
At the recent launch of the twin GRAIL lunar mapping probes, I spoke with Weiler about a wide range of NASA missions. Watch for my upcoming interview with Ed.
Weiler is very hopeful that Hubble will continue to operate for several more years at least.
NASA issued this statement from NASA Administrator Charles Bolden, “Ed leaves an enduring legacy of pride and success that forever will remain a part of NASA’s science history. His leadership helped inspire the public with each new scientific discovery, and enabled NASA to move forward with new capabilities to continue to explore our solar system and beyond.”
The successes under Weiler’s leadership include NASA’s great observatory missions, unprecedented advances in Earth science and extensive exploration of Mars and other planets in our solar system. These advances have rewritten science textbooks and earned enormous support for NASA’s science programs from the general public.
The Mars rovers Spirit and Opportunity are just one example of the science missions approved and funded during Weiler’s tenure.
Weiler’s leadership has been instrumental in securing continued support and funding for NASA Space Science from Congress and the White House. He has received numerous prestigious awards including the NASA Distinguished Service Medal and several Presidential Rank Awards for Meritorious Executive and Distinguished Executive.
China launched their first space station module into orbit today (Sept. 29), marking a major milestone in the rapidly expanding Chinese space program. The historic liftoff of the man ratedTiangong 1 (Heavenly Palace 1) space lab on a Long March 2F rocket took place at 9:16 p.m. local time (9:16 a.m. EDT) from the Jiuquan Satellite Launch Center located in Gansu province in northwest China and is an impressive advance for China.
The beautiful nighttime liftoff occurred exactly on time and was carried live on China’s state run television – CCTV – and on the internet for all to see. Chinese President Hu Jintao and many of China’s other top government leaders witnessed the launch from the Beijing Aerospace Control Center as a gesture of confidence and support. Their presence was a clear sign of just how important China’s top leadership considers investments in research as a major driver of technological innovation that is bolstering China’s vigorously growing economy and employing tens of thousands of people.
The US – in sharp contrast – is cutting space spending and handing out pink slips to many thousands of shuttle workers, CCTV noted.
As a CCTV commentator said after the successful Tiangong 1 launch, “30 Years ago it was ‘science fiction’ to imagine a Chinese astronaut in space. Today it’s a reality!”
Long range cameras tracked rocket for several minutes and clearly showed the jettisoning of the first stage boosters and the payload fairing.
“The launch of Tiangong 1 has been successfully completed,” announced Gen. Chang Wanquan, chief commander of China’s manned space engineering project on CCTV
Tiangiong 1 will serve a crucial role as a docking target to carry out China’s first rendezvous and docking in space- initially with an unmanned vehicle and thereafter with astronauts crews. The US and the Soviet Union mastered these technologies back in the 1960’s, and China is rapidly catching up now.
Rendezvous and docking are key accomplishments that China must achieve in order to move forward and accomplish even more ambitious space goals – construction of a 60 ton space station by the year 2020.
The two stage Long March 2F rocket was upgraded with more than 170 improvements including a larger payload fairing to house bigger Tiangong 1 module, four longer liquid fueled strap on boosters with more powerful thrust capability and more precise guidance systems.
The 8.5 ton Tiangong 1 was designed to stay in space for at least 2 years and support crews of up to three astronauts for short duration stays. It will be the target of at least three upcoming space missions – Shenzhou 8, 9 and 10.
Shenzhou is China’s human spaceflight capsule, derived from the Russian Soyuz and also significantly upgraded with China’s own nationally developed technology.
The unmanned Shenzhou 8 will launch in about 1 month according to officials from the China Manned Space Engineering Office and reach the vicinity of Tiangong 1 after 2 days. Shenzhou 8 will conduct at least two practice test dockings to extensively check out all systems and experience.
Shenzhou 9 and 10 will dock during 2012 and are likely to include the first female Chinese astronaut.
Tiangong 1 is a prototype miniture space station module, not fully outfitted for long duration stays of astronauts. The space lab consists of two segments – a forward habitable, pressurized section for the astronauts (measuring some 530 cubic feet in volume) and an unpressurized resource compartment in the rear with two solar arrays consisting of four segments to provide ample power.
Student Alert ! – Here’s your once in a lifetime chance to name Two NASA robots speeding at this moment to the Moon on a super science mission to map the lunar gravity field. They were successfully launched from the Earth to the Moon on September 10, 2011. Right now the robots are called GRAIL A and GRAIL B. But, they need real names that inspire. And they need those names real soon. The goal is to “capture the spirit and excitement of lunar exploration”, says NASA – the US Space Agency.
NASA needs your help and has just announced an essay writing contest open to students in Grades K – 12 at schools in the United States. The deadline to submit your essay is November 11, 2011. GRAIL stands for “Gravity Recovery And Interior Laboratory.”
The rules state you need to pick two names and explain your choices in 500 words or less in English. Your essay can be any length up to 500 words – even as short as a paragraph. But, DO NOT write more than 500 words or your entry will be automatically disqualified.
Learn more about the GRAIL Essay Naming Contest here:
The GRAIL A and B lunar spaceships are twins – just like those other awe inspiring robots “Spirit” and “Opportunity” , which were named by a 10 year old girl student and quickly became famous worldwide and forever because of their exciting science missions of Exploration and Discovery.They arrive in Lunar Orbit on New Year’s Day 2012.
And there is another way that students can get involved in NASA’s GRAIL mission.
GRAIL A & B are both equipped with four student-run MoonKAM cameras. Students can suggest targets for the cameras. Then the cameras will take close-up views of the lunar surface, taking tens of thousands of images and sending them back to Earth.
“Over 1100 middle schools have signed up to participate in the MoonKAM education and public outreach program to take images and engage in exploration,” said Prof. Maria Zuber of MIT.
Prof. Zuber is the top scientist on the mission and she was very excited to announce the GRAIL Essay Naming contest right after the twin spaceships blasted off to the Moon on Sep 10, 2011 from Cape Canaveral in Florida.
What is the purpose of GRAIL ?
“GRAIL simply put, is a ‘Journey to the Center of the Moon’,” says Dr. Ed Weiler, NASA Associate Administrator of the Science Mission Directorate in Washington, DC.
“It will probe the interior of the moon and map its gravity field by 100 to 1000 times better than ever before. We will learn more about the interior of the moon with GRAIL than all previous lunar missions combined. Precisely knowing what the gravity fields are will be critical in helping to land future human and robotic spacecraft. The moon is not very uniform. So it’s a dicey thing to fly orbits around the moon.”
“There have been many missions that have gone to the moon, orbited the moon, landed on the moon, brought back samples of the moon,” said Zuber. “But the missing piece of the puzzle in trying to understand the moon is what the deep interior is like.”
So, what are you waiting for.
Start thinking and writing. Students – You can be space explorers too !

China’s human spaceflight program is gearing up to take a highly significant “Leap forward in Space” after their “Tiangong 1” prototype space station was rolled out to the remote Gobi desert launch pad at the countries Jiuquan Satellite Launching Center in Gansu Province in anticipation of blastoff sometime this week.
Space officials from the Chinese Manned Space Engineering Office have now confirmed that liftoff of the 8.5 ton Tiangong 1 human rated module atop a Long March CZ-IIF booster rocket is slated to take place during a launch window that extends from Sept. 27 to Sept. 30. The launch was delayed a few days after the recent launch failure of a similar Chinese rocket, the Long March IIC.
China’s burgeoning space efforts come directly on the heels of the voluntary USshutdown of the Space Shuttle program, thereby dismantling all US capability to launch humans into space from American soil for several years until about 2014 at a minimum.
The US manned spaceflight capability gap will be stretched out even further if NASA’s budget for commercial space taxis and the newly proposed SLS launch system is cut by political leaders in Washington, DC.
On Sept. 20, the integrated Long March rocket and Tiangong module were wheeled out of China’s VAB while sitting on top of the Mobile Launch Platform and transferred to the launch gantry at Jiuguan.
The goal of the Tiangong 1 mission is to carry out China’s first human spaceflight related rendezvous and docking mission and to demonstrate that Chinese space engineers have mastered the complicated technology required for a successful outcome.
These skills are akin in complexity to NASA’s Gemini manned program of the 1960’s which paved the way for NASA’s Apollo missions and led directly to the first manned landing on the moon in 1969 by Apollo 11.
Chinas stated goal is to construct a 60 ton Skylab sized space station in earth orbit by 2020.
Check out this CCTV video for further details and imagery of the Chinese space hardware which shows the how China will expand the reach and influence of their space program.
View this Chinese video from NDTV for a glimpse at Chinas long range Space Station plans.
The 40 foot long Tiangong 1 space platform is unmanned and will serve as the docking target for China’s manned Shenzhou capsules in a series of stepping stone learning flights. It is solar powered and equipped to operate in a man-tended mode for short duration missions and in an unmanned mode over the long term.
The initial rendezvous and docking mission will be conducted by the Shenzhou 8 spacecraft, which will fly in an unmanned configuration for the first docking test. Shenzhou 8 is scheduled to soar to space before the end of 2011.
If successful, China plans to quickly follow up with the launch of two manned Shenzhou flights to dock at Tiangong 1 during 2012 – namely Shenzhou 9 & Shenzhou 10.
The multi astronaut chinese crews would float into Tiangong 1 and remain on board for a short duration period of a few days or weeks. The crew would conduct medical, space science and technology tests and experiments.
China’s first female astronaut may be selected to fly as a crew member on one of the two Shenzhou flights in 2012.
Meanwhile, all American astronauts will be completely dependent on the Russian Soyuz capsule for trips to the International Space Station. Russia is still working to correct the third stage malfunction which doomed the recent Progress cargo resupply launch and put a halt to Soyuz launches.
Engineers and technicians are in the process of checking out all Tiangong 1 systems and preliminary weather reports from Chinese media appear favorable for launch.
Shenzhou 8 has also been delivered to the Jinquan launch complex for check out of all systems
Get set for China’s attempt at a ‘Space Spectacular’
Opportunity has just been imaged in high resolution at Endeavour crater by a powerful NASA camera orbiting overhead in Mars orbit. The new image (see above) was snapped while NASA’s long lived robot was climbing a hilltop offering spectacular panoramic vistas peering into the vast crater which is some 14 miles (22 km) wide.
The HiRiSE camera aboard NASA’s Mars Reconnaissance Orbiter photographed Opportunity and her wheel tracks on September 10, 2011, or Martian Sol 2712 for a mission warrentied to last only 90 Sols ! The rover is sitting to the right of another small crater known as Odyssey. Click to enlarge the image.
Look very closely and you’ll even be able to easily discern the rovers pair of tire tracks showing the path traversed by the robot as she explores the crater and the ejecta rocks and boulders excavated and strewn about by an ancient impact.
Opportunity is ascending up the rim of Endeavour crater at the southern tip of a low ridge dubbed Cape York – a location that has already yielded a bonanza of new science data since her recent arrival in August 2011 after a more than 20 mile (33 km) epic trek.
The intrepid rover discovered a rock unlike any other since she safely landed at the Meridiani Planum region of Mars nearly eight years ago on Jan. 24, 2004.
Opportunity is now searching Endeavour crater and Cape York for signatures of phyllosilicates – clay minerals that formed in the presence of pH neutral water flowing on Mars surface billions of years ago.
Try not to plummet off a steep crater cliff or be buried under a landslide while gazing at the irresistibly alluring curves of beautiful Rheasilvia – the mythical mother of Romulus and Remus – whose found a new home at the South Pole of the giant Asteroid Vesta.
3 D is undoubtedly the best way to maximize your pleasure. So whip out your cool red-cyan anaglyph glasses to enhance your viewing experience of Rheasilvia, the Snowman and more – and maximize your enjoyment of this new 3 D collection showcasing the heavily cratered, pockmarked, mountainous and groovy terrain replete at Vesta.
Scientists and mortals have been fascinated by the enormous impact crater Rheasilvia and central mountain unveiled in detail by NASA’s Dawn Asteroid Orbiter recently arrived at Vesta, the 2nd most massive object in the main asteroid belt. Ceres is the largest object and will be Dawn’s next orbital target in 2015 after departing Vesta in 2012.
“Vesta is the smallest terrestrial planet in our Solar System”, said Chris Russell in an interview with Universe Today. “We do not have a good analog to Vesta anywhere else in the Solar System.”
And the best is yet to come. In a few days, Dawn begins snapping images from a much lower altitude at the HAMO mapping orbit of ca. 685 km vs the initial survey orbit of ca, 2700 km. where most of these images were taken.
Can you find the location of the 3 D South Pole images above in the 2 D South Pole image below?
