The first ever Vesta Vista snapped from the protoplanets orbit has been transmitted back through 117 million miles of space to eager eyes waiting on Earth. Although Vesta had been observed by telescopes on Earth and in space for more than two centuries since its discovery, only scant detail on its surface could be discerned until today.

NASA’s Dawn spacecraft took the new photo of the giant asteroid Vesta on July 17 – enhanced version shown above – less than 2 days after making space history as the first probe ever to enter orbit about an object in the main Asteroid Belt. The team also released their first 3 D image of Vesta. Read my orbital capture story here and see the original NASA image below.

“I think it is truly thrilling to be turning what was little more than a fuzzy blob for two centuries into a fascinating alien world,” said Dawn Chief Engineer Marc Rayman in a new post orbit interview with Universe Today.

Vesta is 330 miles (530 kilometers) in diameter and the second most massive object in the Asteroid Belt between Mars and Jupiter.

“And the closer Dawn gets to Vesta, the more exotic and intriguing the pictures become !,” added Rayman.

Dawn was captured into orbit at an altitude of 9,900 miles (16,000 km) at 1 a.m. EDT on July 16 according to Rayman, of the Jet Propulsion Lab in Pasadena, Calif. and is now slowly descending over the next few weeks.

“The spacecraft remains healthy, and our spiral down to Vesta is going well,” Rayman told me.

The new photo from orbit is nearly centered on the south pole which suffered a devastation cosmic collision eons ago. That blast sent huge plumes of ejecta streaming out, including towards Earth. About 5% of all known meteorites stem from Vesta.

“The south pole is a bulging feature in the images,” said Prof. Chris Russll, Dawn’s Science Principal Investigator of UCLA in an interview.

“The pole is not centered on this feature but is close to it. We have not finalized our determination of the pole but are close to a ‘final’ answer. We are not making interpretations at this point because the greater resolution that is coming will make all today’s speculations moot,” Russell stated.

Vesta Sizes Up
This composite image shows the comparative sizes of nine asteroids visited by Earthly spaceships. Up until now, Lutetia, with a diameter of 81 miles (130 kilometers), was the largest asteroid visited by a spacecraft, which occurred during a flyby. Vesta, which is also considered a protoplanet because it's a large body that almost became a planet, dwarfs all other small bodies in this image, with its diameter sizing up at approximately 330 miles (530 kilometers).

By early August, Dawn will have gently been nudged into its initial science observation orbit at an altitude of approximately 1700 miles above the scarred surface of newly discovered mountains, craters, grooves, scarps and more.

During the approach phase, the Dawn team will accomplish multiple tasks with its onboard systems and three science instruments; including the search for possible moons, observing Vesta’s physical properties and obtaining calibration data.

But don’t expect a continuous stream of new pictures, according to Russell.

“We will not have a steady stream of images until we are in one of our
three science phases,” Russell told me. “When we are in transit from one place to another we thrust, stop, turn, image, turn, transmit, turn, thrust, and several days later repeat. All time spent not thrusting is time taken away from science later.”

“The next image is scheduled to be snapped on Saturday July 23.”

We will learn a lot more at the next press conference scheduled to take place on Monday August 1 from JPL.

Dawn will spend one year orbiting around Vesta and collecting high resolution mapping images, determining the chemical composition and measuring its gravity field. Then it will fire its ion thrusters to propel the probe to a second destination, the dwarf planet Ceres, arriving in February 2015.

The Asteroid Belt is one of the last unexplored regions of our solar system.

“We are beginning the study of arguably the oldest extant primordial surface in the solar system,” elaborated Russell in a NASA statement. “This region of space has been ignored for far too long. So far, the images received to date reveal a complex surface that seems to have preserved some of the earliest events in Vesta’s history, as well as logging the onslaught that Vesta has suffered in the intervening eons.”

This image, taken by the framing camera instrument aboard NASA's Dawn spacecraft, shows the south polar region of this object, which has a diameter of 330 miles (530 kilometers). The image was taken through the clear filter on July 9, 2011, as part of a rotation characterization sequence, and it has a scale of about 2.2 miles (3.5 kilometers) per pixel. To enhance details, the resolution was enlarged to 0.6 miles (1 kilometer) per pixel. This region is characterized by rough topography, a large mountain, impact craters, grooves and steep scarps.

Dawn Exceeds Wildest Expectations as First Ever Spacecraft to Orbit a Protoplanet – Vesta

Enhanced Image of Vesta Captured by Dawn on July 9, 2011. NASA's Dawn spacecraft entered orbit around Vesta on July 16, 2011. Dawn obtained the raw image of Vesta with its framing camera on July 9, 2011 - which has been enhanced and annotated.

NASA’s super exciting Dawn mission to the Asteroid Belt marked a major milestone in human history by becoming the first ever spacecraft from Planet Earth to achieve orbit around a Protoplanet – Vesta – on July 16. Dawn was launched in September 2007 and was 117 million miles (188 million km) distant from Earth as it was captured by Asteroid Vesta.

Dawn’s achievements thus far have already exceeded the wildest expectations of the science and engineering teams, and the adventure has only just begun ! – so say Dawn’s Science Principal Investigator Prof. Chris Russell, Chief Engineer Dr. Marc Rayman (think Scotty !) and NASA’s Planetary Science Director Jim Green in exclusive new interviews with Universe Today.

As you read these words, Dawn is steadily unveiling new Vesta vistas never before seen by a human being – and in ever higher resolution. And it’s only made possible via the revolutionary and exotic ion propulsion thrusters propelling Dawn through space (think Star Trek !). That’s what NASA, science and space exploration are all about.

“Dawn is in orbit, remains in good health and is continuing to perform all of its functions,” Marc Rayman of the Jet Propulsion Laboratory, Pasadena, Calif., told me. “Indeed, that is how we know it achieved orbit. The confirmation received in a routine communications session that it has continued thrusting is all we needed.”

Dawn entered orbit at about 9900 miles (16000 km) altitude after a nearly 4 year journey of 1.73 billion miles.

Over the next few weeks, the spacecrafts primary task is to gradually spiral down to its initial science operations orbit, approximately 1700 miles above the pock marked surface.

Vesta is the second most massive object in the main Asteroid Belt between Mars and Jupiter. Dawn is the first probe to orbit an object in the Asteroid Belt.

I asked Principal Investigator Chris Russell from UCLA for a status update on Dawn and to describe what the team can conclude from the images and data collected thus far.

“The Dawn team is really, really excited right now,” Russell replied.

“This is what we have been planning now for over a decade and to finally be in orbit around our first ‘protoplanet’ is fantastic.”

“The images exceed my wildest dreams. The terrain both shows the stress on the Vestan surface exerted by 4.5 billion years of collisions while preserving evidence [it seems] of what may be internal processes. The result is a complex surface that is very interesting and should be very scientifically productive.”

“The team is looking at our low resolution images and trying to make preliminary assessments but the final answers await the higher resolution data that is still to come.”

Russell praised the team and described how well the spacecraft was operating.

“The flight team has been great on this project and deserves a lot of credit for getting us to Vesta EARLY and giving us much more observation time than we had planned,” Russell told me.

“And they have kept the spacecraft healthy and the instruments safe. Now we are ready to work in earnest on our science observations.”

Dawn will remain in orbit at Vesta for one year. Then it will fire its ion thrusters and head for the Dwarf Planet Ceres – the largest object in the Asteroid Belt. Dawn will then achieve another major milestone and become the first spacecraft ever to orbit two celestial objects.

Jim Green, Director of Planetary Science for the Science Mission Directorate (SMD) at NASA HQ in Washington, DC, summed up his feelings about Dawn in this way;

“Getting Dawn into orbit is an amazing achievement,” Green told me.

“Instead of the ‘fire the thrusters full blast’ we just sort of slid into orbit letting gravity grab the spacecraft with a light tug. This gives us great confidence that the big challenge down the road of getting into orbit around Ceres can also be accomplished just as easily.”

Sharper new images from Vesta will be published by NASA in the next day or so.

“We did take a few navigation images in this last sequence and when they get through processing they should be put on the web this week,” Russell informed. “These images are from a similar angle to the last set and with somewhat better resolution and will not reveal much new.”

However, since Dawn is now orbiting Vesta our upcoming view of the protoplanet will be quite different from what we’ve seen in the approach images thus far.

“We will be changing views in the future as the spacecraft begins to climb into its science orbit,” stated Russell.

“This may reveal new features on the surface as well as giving us better resolution. So stay tuned.”

Marc Rayman explained how and why Dawn’s trajectory is changing from equatorial to polar:

“Now that we are close enough to Vesta for its gravity to cause a significant curvature in the trajectory, our view is beginning to change,” said Rayman. “That will be evident in the pictures taken now and in the near future, as the spacecraft arcs north over the dark side and then orbits back to the south over the illuminated side.”

“The sun is over the southern hemisphere right now,” added Russell. “When we leave we are hoping to see it shine in the north.”

Dawn is an international mission with significant participation from Germany and Italy. The navigation images were taken by Dawn’s framing cameras which were built in Germany.

Exploring Vesta is like studying a fossil from the distant past that will immeasurably increase our knowledge of the beginnings of our solar system and how it evolved over time.

Vesta suffered a cosmic collision at the south pole in the distant past that Dawn can now study at close range.

“For now we are viewing a fantastic asteroid, seeing it up close as we zero in on its southern hemisphere, looking at the huge central peak, and wondering how it got there,” explained Jim Green

“We know Vesta was nearly spherical at one time. Then a collision in its southern hemisphere occurred blowing off an enormous amount of material where a central peak now remains.”

That intriguing peak is now obvious in the latest Dawn images from Vesta. But what does it mean and reveal ?

“We wonder what is that peak? replied Green. “Is it part of the core exposed?

“Was it formed as a result of the impact or did it arise from volcanic action?”

“The Dawn team hopes to answer these questions. I can’t wait!” Green told me.

As a result of that ancient south pole collision, about 5% of all the meteorites found on Earth actually originate from Vesta.

Keep your eyes glued to Dawn as mysterious Vesta’s alluring secrets are unveiled.

Stripped Down Discovery rolls towards Retirement at Kennedy Space Center

Space Shuttle Discovery was briefly on public display on Wednesday July 13 as she emerged from the hanger at the Kennedy Space Center where she has been undergoing processing for retirement since her final landing on the STS-133 mission.

It was a rather stark and sad moment because Discovery looked almost naked and downtrodden – and there was no doubt that she would never again fly majestically to space because huge parts of the orbiter were totally absent.

Discovery was stripped bare of her three main engines and orbital maneuvering pods at the rear and she had a giant hole in the front, just behind the nose, that was covered in see through plastic sheeting that formerly housed her now missing forward thrusters. Without these essential components, Discovery cannot move 1 nanometer.

When the Space Shuttle is forcibly retired in about a week, America will have no capability to launch astronauts into space and to the International Space Station for many many years to come.

Discovery was pulled a quarter mile from the Orbiter Processing Facility (OPF) to the Vehicle Assembly Building (VAB) to make room for Space Shuttle Atlantis when she returns next week from the STS-135 mission, according to Stephanie Stilson, the flow manager for Discovery, in an interview with Universe Today.

STS-135 is the 135th and final mission of NASA’s 30 year long Space Shuttle Program.

NASA now only has control of two of the three shuttle OPF’s since one OPF has been handed over to an unnamed client, Stilson said.

Stilson is leading the NASA team responsible for safing all three Space Shuttle Orbiters. “We are removing the hypergolic fuel and other toxic residues to prepare the orbiters for display in the museums where they will be permanently housed.”

“The safing work on Discovery should be complete by February 2012,” Stilson told me. “NASA plans to transport Discovery to her permanent home at the Smithsonian Air and Space Museum on April 12, 2012, which coincides with the anniversary of the first shuttle launch on April 12, 1981.”

NASA welcomed the very last spent Shuttle Solid Rocket Boosters (SRB’s) back into port with a special water cannon salute today (July 10) at Port Canaveral, Florida. The twin boosters parachuted back to Earth after powering Atlantis’ historic final ascent to orbit for the first two minutes following blastoff of the STS-135 mission from the Kennedy Space Center (KSC) on July 8.

After splashdown into the Atlantic Ocean, the boosters were towed back individually by two NASA naval vessels named Freedom Star and Liberty Star. See my photo album.

This beautiful photo op is free and open to the public – and has been since the beginning of the space shuttle program 30 years ago.

Atlantis’ right SRB was towed back first by Liberty Star and arrived at Port Canaveral jetty at about 12 p.m. EDT. Freedom Star came in at about 11 p.m.

Both NASA ships are typically manned by a crew numbering 24 team members. The ocean retrieval normally takes about two days.

The water cannon tribute was specially commissioned to honor the ocean retrieval of the last shuttle SRB’s that will ever fly.

“The future of Liberty Star and Freedom Star remains to be decided,” according to KSC spokesperson Allard Beutel in an interview. “The ships are available for use. SpaceX rented out one of the ships in an attempt to retrieve the first stage of the Falcon 9 during their two launches from Cape Canaveral.”

Space Shuttle Atlantis soared to space for one last history-making time today July 8 at 11:29 a.m. despite a gloomy weather forecast, low lying clouds and a last moment countdown glitch that threatened to derail the launch in the closing seconds – but ultimately all coalesced and combined for an unpredictably tense drama that went down to the wire and put on a heart pounding and spectacular sky show.

About 750,000 spectators jammed the Florida space coast beaches, roadways and motels to witness a historic event that we will never see again.

A hole in the sky miraculously appeared above the Kennedy Space Center and with just 58 seconds remaining in the launch window, NASA launch managers lit Atlantis engines and the shuttle stack thundered to life and vaulted off Launch Pad 39 A on 7 million pounds of thrust for NASA’s 135th and final shuttle mission.

“What a truly awesome day today,” said NASA Associate Administrator for Space Operations Bill Gerstenmaier at the STS-135 post launch news conference for reporters. ” We got to witness something really, really special and something really amazing. I’m really talking about the teams and the people who supported the launch that just occurred. What you saw is the finest launch team and shuttle preparation teams in the world.”

“It truly was an awesome, spectacular launch,” added Kennedy Space Center Director Bob Cabana.

“We’re really looking forward to a great mission. This is a very critical mission for station resupply. We’re going to do our best to try and stretch out an extra day,” said Space Shuttle Program Launch Integration Manager and chairman of the pre-mission Mission Management Team Mike Moses. “I think the shuttle program is ending exactly as it should. We’ve built the International Space Station, we’re stocking it up for the future, and ready to hand it off, and we finish really, really strong.”

“On behalf of the launch team, and all the thousands of people here at KSC, we’re just very, very proud that we finished strong from the launch perspective,” added Shuttle Launch Director Mike Leinbach.

“A lot of us walked around and shook everybody’s hand,” Leinbach told reporters at the packed press conference. “It seemed like we didn’t want to leave, it was like the end of a party and you just don’t want to go, you just want to hang around a little bit longer and relish our friends and what we accomplished. It was very special, lots of pats on the back today.”

The last Space Shuttle in history that will blast off for space was unveiled today at the Kennedy Space Center (KSC) in Florida amidst terrible weather. Heavy rain showers and thunderstorms are inundating the space center during prelaunch preparations for the blast off of Space Shuttle Atlantis.

Two lightning strikes occurred within about a third of a mile of Launch Pad 39 at 12:31 p.m. and 12:40 p.m. EDT. After engineering teams evaluated data from the strikes, NASA shuttle managers decided it was safe to proceed with launch preparations.

Following about a 40 minute delay, Atlantis was unveiled for liftoff after retraction of the massive rotating service structure which protects the orbiter from inclement weather and impacts from foreign object debris.

The chances of favorable weather for launch of the STS-135 mission on Friday July 8 are just 30%, meaning 70% NO GO said Shuttle Weather officer Kathy Winters at a briefing for reporters today at KSC. Liftoff is targeted for 11:26 a.m. EDT.

NASA has a narrow window of three opportunities on July 8, 9 and 10 and must then stand down for nearly a week because the US Air Force has scheduled a Delta rocket launch on July 14. If the Air Force would agree to delay the Delta by few days, NASA could launch Atlantis on Monday or Tuesday in case for further launch delays.

Upwards of 750,000 spectators are expected.

Atlantis goal is deliver the Raffaello logistics module and the Robotic Refueling Mission to the ISS on a 12 day mission that will end the shuttle era.

Hubble: One in a Million

For those of you bummed that Hubble’s one millionth observation didn’t include an eye-popping image, Daniel Pendick from the Geeked on Goddard Blog has put together a video of over 200 classic Hubble images, with the funky music from the “Planets” album by the band One Ring Zero. “Planets” is a collection of new compositions to represent the solar system and beyond. Gustav Holst its not, but it is “an eclectic and quirky journey from Mercury to Pluto, with influences as diverse as gypsy violin, Pink Floyd and David Bowie, Electric Light Orchestra, and even klezmer,” said Pendick on the 365 Days of Astronomy podcast. Enjoy!

The countdown to NASA’s 135th and final shuttle launch began today (July 5) with no technical issues blocking liftoff at this time. But upwards of 750,000 spectators may be disappointed because the weather on launch day, July 8, is looking decidedly dicey. Storm weather and stormy seas lie ahead for NASA.

At today’s press briefing, Shuttle Weather Officer Kathy Winters projected that the chance of favorable weather is only 40% for Friday’s 11.26 a.m. liftoff of Atlantis because of the likely threat of rain at the Kennedy Space Center.

The 12 day STS-135 mission will loft about 9500 pounds of supplies and equipment that NASA shuttle managers state are absolutely “mandatory” in order to keep the International Space Station operating at full capacity for the next year.

“I wish I had a better weather briefing for you, but it does look like we are going to have some weather, at least potential for weather, in the area at launch time,” said Winters. “Right now, we’re going with a 60 percent chance of KSC weather prohibiting launch due to the potential for showers and isolated thunderstorms in the area.”

In the event of a one day delay to Saturday, the chances for favorable weather increases considerably to 60%. For a two day delay to July 10, the chances of acceptable weather climbs to 70%.

After July 10, the liftoff of the STS-135 mission would have to be delayed to July 16 because NASA would be forced to stand down shuttle launch operations in order to allow the Air Force to launch a military navigation satellite on July 14 from Cape Canaveral. That is unless the Air Force relents – out of consideration for the three quarters of a million folks expected to jam the Florida space coast beaches, highways and hotels – and offers NASA the opportunity to launch Atlantis for several days starting on July 11 – in case of a launch delay.

Space fans need to be patient and plan for undesired contingencies just like NASA by packing extra provisions like food, water and clothing and also should consider extended accommodations.

Clocks began ticking backwards today at 1p.m.EDT at the T Minus 43 hour mark towards the final blastoff of Space Shuttle Atlantis.

NASA Test Director Jeremy Graeber said at today’s briefing that Atlantis is ready to fly.

“Our teams here at the Kennedy Space Center and all the NASA centers across the country have been working for over a year to prepare Atlantis, the external tank our solid rocket boosters, the payload and all of our ground systems for the STS-135 mission,” Graeber stated. “All of our vehicle and ground systems are ready, the STS-135 crew, Atlantis and the launch team are all ready to proceed and we’re looking forward to a spectacular launch on Friday morning.”

STS-135 payload manager Joe Delai said the payloads and the Raffaello cargo carrier module are ready to go as well. “The primary objective of Atlantis is to resupply the ISS for one year. About 9500 pounds are going up. This is the largest payload in terms of volume.”

Delai said that Raffaello was specially modified to increase its cargo carrying capacity by several hundred pounds.

The STS-135 mission will bring NASA’s 30 year long shuttle program to a definite close and simultaneously mark the termination of the US capability to launch humans to space for at least several years.

The four astronauts who will fly the Grand Finale of NASA’s space shuttle program arrived at the Florida launch site on Independence Day on a wave of T-38 training jets. The veteran crew flew into the Kennedy Space Center (KSC) from Ellington Field in Houston, Texas and touched down at the shuttle landing strip at about 2:30 p.m. EDT.

Blast off of Space Shuttle Atlantis on the STS-135 mission is slated for July 8 at 11.26 a.m. with Shuttle Commander Chris Ferguson at the helm. He is joined by Pilot Doug Hurley and Mission Specialists Sandy Magnus and Rex Walheim.

Upon landing in the sweltering Florida heat, the astronauts were welcomed by Space Shuttle Launch Director Mike Leinbach as well as other NASA/KSC officials and a large crowd of media. Many waved US flags in honor of the July 4th Independence Day holiday.

“I think I speak for the whole crew in that we are delighted to be here after a very arduous nine month training flow and we’re thrilled to finally be here in Florida for launch week,” said Ferguson. “This is a day that’s decidedly American, a day where we kind of reflect on our independence and all the wonderful things that we really have as part of being the United States of America. I think it’s wonderful you’ve all come out to join us.”

“We have a very event-filled mission ahead of us, we have 12 days, we’ll be very, very busy,” Ferguson added. “When it’s all over, we’ll be very proud to put the right-hand bookend on the space shuttle program.”

The quartet will spend the next few days completing final prelaunch training to prepare for their planned 12 day flight bound for the International Space Station.

The primary cargo is the Raffaello Multipurpose Logistics module built in Italy and jam packed with some five tons of spare parts, science gear, food, water, clothing and more that will be transferred to the station by the station and shuttle crews and are absolutely essential to keep the orbiting outpost operating over the next year.

About 2000 journalists and photographers are expected to cover Atlantis’s launch, the largest media gathering for a shuttle launch since the Return to Flight in 2005 – that’s about twice the media here for the last launch of Endeavour in April.

Assembly of NASA’s first Orion Crew vehicle that could actually launch to space has been accomplished by prime contractor Lockheed Martin Corporation at the firm’s Waterton space systems facility located near Denver, Colorado, where the spacecraft is slated to begin a severe testing process that will help confirm crew safety.

Orion is NASA’s next generation spacecraft designed to send human crews to low Earth Orbit and beyond to multiple deep space destinations throughout our solar system including the Moon, Mars and Asteroids. Orion was recently recast as the MPCV or Multi Purpose Crew Vehicle in the NASA Authorization Act of 2010.

“The first Orion crew module built to spaceflight specifications is complete,” said Linda Singleton, a spokesperson for Lockheed Martin in an interview.

“Orion will soon be integrated with the launch abort system test article prior to undergoing acoustic, vibration and modal testing in Denver,” Singleton told me. “The testing process will last several months.”

Watch this cool and detailed animation of the testing process to be conducted at the Reverberant Acoustic Lab at Lockheed Martin’s Waterton Facility.

The video also shows how the Orion will be integrated and tested with the Launch Abort System (LAS) that would save the lives of the astronauts on board in the event of a spaceflight emergency.

With the Grand Finale of NASA’s Space Shuttle Program now just days away after the launch of shuttle Atlantis on the STS-135 mission, the US faces a gap with no capability to send humans to space and the International Space Station for a time period extending at least several years.

A replacement vehicle for the retiring shuttle – whether its the Orion or from a commercial provider like SpaceX – can’t come soon enough in order to maintain the viability of the International Space Station.

This Orion vehicle also known as the Ground Test Article, or GTA, will now be subjected to several months of rigorous flight like testing that simulates the harsh environments that astronauts would face during voyages to deep space.

Thereafter, the Orion crew module will be transported in early 2012 to NASA’s Langley Research Center in Virginia where it will undergo water landing drop tests next year at the new Hydro Impact Basin facility.

“The NASA and Lockheed Martin teams hope to achieve Orion/MPCV initial crewed operations by 2016”, said Singleton. “We are aiming for an initial unmanned orbital test flight in 2013.”

A Delta IV Heavy booster rocket is the most likely candidate for the 2013 Orion orbital flight, but a final decision has not yet been announced by NASA.

Meanwhile, another Orion crew module that was flown during the Pad Abort 1 test (PA-1) in 2010 is now on public display at the Kennedy Space Center Visitor Complex in Florida. The vehicle just arrived after a cross country trek from NASA’s Dryden Flight Research Center in California and making several public outreach stops along the way to Florida.

The Orion PA-1 test article is on display until July 4 in the historic Rocket Garden at Kennedy in the shadow of a mighty Saturn 1B and alongside Mercury, Gemini and Apollo Era capsules and rockets. The mockup of the LAS is also still on display at the Kennedy Visitor Complex.
