Barely discernable in the pre-dawn twilight and appearing as an eerie, ghost like figure, Space Shuttle Atlantis and her four person crew swiftly glided to a triumphant landing at the Kennedy Space Center that closed out NASA’s three decade long Space Shuttle Era – in the wink of an eye it was all over.

Atlantis touched down almost invisibly on Runway 15 at the Shuttle Landing Facility at 5:57 a.m. EDT and rolled to a stop moments later to conclude the history making 13 day flight to the International Space Station and back. During the STS-135 mission Atlantis orbited the Earth 200 times and journeyed 5,284,862 miles.

The all veteran crew of space flyers comprised of Shuttle Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim.

The finality of it all was at once thoroughly unbelievable that the shuttles would never fly again but utterly definitive at ‘wheel stop’ that we had witnessed the end of a historic and magnificent Era in human spaceflight.

Everyone present at the shuttle landing strip let out a loud cheer and thankful applause upon the safe conclusion to the 135th and last flight of NASA’s Space Shuttle Program – since the first blastoff of Columbia on the STS-1 mission on April 12, 1981.

“Mission complete, Houston,” radioed Commander Ferguson. “After serving the world for over 30 years, the space shuttle has earned its place in history. It’s come to a final stop.”

But the sinking realization that America at that exact moment had simultaneously and voluntarily lost 100% of our indigenous national capability to send humans and cargo to the International Space Station is quite troubling to say the least.

The end of the shuttle program also marked the end of employment for nearly 2000 highly talented shuttle workers in the midst of a continuing tough economic situation all across the US. And thousand more pink slips are looming.

The primary goal of the STS-135 mission was to deliver more than 9,400 pounds of spare parts, food, water, science experiments and assorted gear to the International Space Station that were loaded aboard the Raffaello multi-purpose logistics module – which functions as a ‘moving van’ in space.

All these supplies are “absolutely mandatory”, according to top NASA managers, for sustaining ISS operations for about one year into 2012. By that time NASA hopes that two US commercial space companies – SpaceX and Orbital Sciences – will have flown successful unmanned cargo flights to replace the capability completely lost with the premature retirement of NASA’s three orbiter fleet of winged Space Shuttles.

For the return trip to Earth, the 21-foot long, 15-foot diameter Raffaello brought back nearly 5,700 pounds of valuable science samples and unneeded trash to free up coveted storage space aboard the massive orbiting outpost.

“Although we got to take the ride,” said Commander Chris Ferguson on behalf of his crew,” we sure hope that everybody who has ever worked on, or touched, or looked at, or envied or admired a space shuttle was able to take just a little part of the journey with us.”

Upon departing Atlantis at the shuttle runway, Ferguson and the entire crew were welcomed back by NASA Administrator Charles Bolden and other senior officials.

“They have come to be known as the ‘final four.’ They did an absolutely incredible job,” said Bolden. “They made us very proud.”

“I really want to thank the space shuttle team and the Space Shuttle Program for just a tremendous effort today and throughout the entire history of the program. We gave them a tremendous challenge to fly and execute these missions and to finish strong and I can tell you today that the team accomplished every one of those objectives,” said Associate Administrator for Space Operations Bill Gerstenmaier at a post landing briefing for reports at the Kennedy Space Center. “I’d also like to thank the nation for allowing us to have these thirty years to go use the shuttle system.”

“It is great to have Atlantis safely home after a tremendously successful mission — and home to stay,” said Bob Cabana, Kennedy Space Center director.

Atlantis future retirement home will be constructed just a short distance away at Kennedy Space Center Visitor Complex (KSCVC).

Visitor Complex COO Bill Moore told me that he expects Atlantis will be put on permanent public display in 2013 after completion of a new 64,000 sq. ft exhibition building to house the orbiter. Atlantis will be displayed as though it were “In Flight.”

“I’m unbelievably proud to be here representing the Space Shuttle Program and the thousands of people across the country who do the work,” said Mike Moses, space shuttle launch integration manager. “Hearing the sonic booms as Atlantis came home for the last time really drove it home to me that this has been a heck of a program.”

“The workers out here and across the country in the Space Shuttle Program have dedicated their lives, their hearts and their souls to this program, and I couldn’t be more proud of them,” said Mike Leinbach, the space shuttle launch director at KSC.

Altogether Atlantis flew 33 missions, spent 307 days in space, orbited Earth 4,848 times and traveled 125,935,769 miles. Atlantis was the last of NASA three orbiters to be retired and closed out the Space Shuttle Era.
Wheels stop marked the dreaded end of American manned spaceflight from American soil for many years to come. No one can say with certainty how or when America will again launch humans to space.

From one moment to the next America’s leadership in space position has evaporated – with the utilization of the most capable spaceship ever built and now operating at the peak of its performance yielding instead to reigning uncertainly as to what comes next given the dire outlook for the NASA budget in the foreseeable future.

A new US manned launch system – most likely in the form of a commercial “space taxi” – could perhaps lift off by mid-decade, but the task is formidable and the funding obstacles are sky high.

In the meantime, America is fully dependent on the Russians to loft Americans to space. All US astronauts headed to the ISS for the next three to five years at a minimum will be forced to hitch a ride aboard a Russian Soyuz capsule.

Dawn Spirals Down Closer to Vesta’s South Pole Impact Basin

South Polar Region of Vesta - Enhanced View. NASA's Dawn spacecraft obtained this image centered on the south pole of Vesta with its framing camera on July 18, 2011. The image has been enhanced to bring out more surface details. It was taken from a distance of about 6,500 miles (10,500 kilometers) away from the protoplanet Vesta.

NASA’s Dawn Asteroid Orbiter is now spiraling down ever closer to the protoplanet Vesta – since arriving on July 16 – and capturing magnificent new high resolution images of the huge impact basin at the South Pole that dominates the surface. See enhanced image here.

The Dawn team just released a new image taken by the framing camera on July 18 as the orbiter flew from the day side to the night side at an altitude of 10,500 kilometers above Vesta, the second most massive body in the main Asteroid Belt between Mars and Jupiter.

“I find this picture very dramatic !” exclaimed Dr. Marc Rayman, Dawn Chief Engineer from the NASA’s Jet Propulsion Laboratory in Pasadena, Calif., in an interview with Universe Today.

“Dawn acquired this image after it had flown past the terminator and its orbit began taking it over the night side of Vesta.”

“After having this view, the spacecraft resumed gradually spiraling around its new home, heading for survey orbit where it will begin intensive observations of Vesta,” Rayman told me.

Dawn will reach the initial science survey orbit in early August, approximately 1700 miles above the battered surface. Vesta turns on its axis once very five hours and 20 minutes.

Vesta suffered an enormous cosmic collision eons ago that apparently created a gigantic impact basin in the southern hemisphere and blasted enormous quantities of soil, rocks and dust into space. Some 5% of all meteorites found on Earth originate from Vesta.

“The south pole region was declared to be a large impact basin after the Hubble Space Telescope (HST) data and images were obtained,” elaborated Prof. Chris Russell, Dawn Principal Investigator from UCLA.

“Now that we have higher resolution images we see that this region is unlike any other large impact on a small body but much of our experience here is on icy bodies of similar size,” Russell told me.

Dawn’s new images of Vesta taken at close range from just a few thousand miles away, now vastly exceed those taken by Hubble as it circled in Earth orbit hundreds of millions of miles away and may cause the science team to reevaluate some long held theories.

“The team is looking forward to obtaining higher resolution data over this region to look for confirmatory evidence for the impact hypothesis. They are not yet willing to vote for or against the HST interpretation. Needless to say the team got very excited by this image,” said Russell.

Dawn will orbit Vesta for one year before heading to its final destination, the Dwarf Planet Ceres.

Hoping Forward At The End Of The Shuttle Era

[/caption]

CAPE CANAVERAL Fla. — The last space shuttle mission, STS-135, ended with the landing of the shuttle Atlantis at Kennedy Space Center’s Shuttle Landing Facility at 5:57 a.m. EDT. The air was thick with both humidity and mosquitoes. It was also a day thick with loss. The United States, for the foreseeable future, has lost the ability to launch massive payloads, such as the International Space Station’s Kibo module, into orbit. Lost the capabilities that a manned spacecraft with a robot manipulator system or RMS affords. Lost the ability to chase down wayward satellites, repair them on-orbit or return them to Earth for more intensive work. Lost, at least for the time being, its leadership position in terms of space flight – that position now belongs to Russia with its human-rated Soyuz Spacecraft and unmanned Progress Cargo vessels.

NASA is working to put a positive spin on this new era. The space agency hopes that small, commercial space firms will provide the nation with the capacity to send men and material to orbit as it works to travel beyond low-Earth-orbit (LEO) once again. Only time will tell how successful this direction will be, but there are positive signs that NASA might be on the right path. Following the space program for decades – you learn to hedge your bets. Today’s SpaceX is tomorrow’s Constellation Program.

Twin sonic booms shake me out of my revelry as the shuttle announces its return home. Then, a couple minutes later, there is the roar of the approaching orbiter. This sound comes not from shuttle, but rather from the sound of air being forcibly moved out of the shuttle’s path. I had set up two mini-camcorders to capture the landing, but had decided not to take any pictures. I took a moment, for myself, to watch as the shuttle roared past and landed.

There were a number of events held later in the day to commemorate the occasion. It struck me as odd that folks, some of whom would be in the unemployment line the following day, were celebrating. I decided to skip these events – I’ll celebrate when this nation regains the ability to launch astronauts into LEO. NASA Administrator Charlie Bolden worked to reassure everyone that all was well, given that he mistakenly said that the crew of STS-134 returned today – his words were not that reassuring.

With luck, when the U.S. does return to space again, it will do so on a multitude of different craft, with a multitude of different abilities – and hopefully launch vehicles. If these spacecraft are as different from one another as Boeing’s CST-100 is from Sierra Nevada Corporation’s Dream Chaser – that will be a very good thing – it will mean that many of the capabilities lost today will be replaced, albeit on completely separate vehicles.

That said, we are now entering an undiscovered country, one that NASA has never delved into before. Near the end of Apollo, the shuttle program was approved. With the end of the shuttle program here – NASA has no established human space flight program, it has initiatives, but no umbrella program, no clear path. That said, there are some potentially amazing things on the horizon – but they exist primarily on paper or on PowerPoint. Until they are fleshed out, until they fulfill their promises – today was a day of loss. Like the shuttle program, today was a mixed bag. One filled with hope for what might come, but uncertainty with what the future holds.

These are my personal reflections on the end of the shuttle program. They do not represent the opinions of Universe Today. These thoughts come from following and covering the space program for the last two decades and are not in favor of any one group’s position. I do not work to tell people things I think they want to hear – but what I feel they need to hear. I appreciate and welcome a mature debate with respect given by all sides for everyone’s point of view.

Love of Science Drives Last Shuttle Commander – Chris Ferguson Brings Science Museum to Orbit

In the weeks leading up to the launch of Space Shuttle Atlantis, I had the distinct honor to speak on several occasions with Chris Ferguson, the Space Shuttle Commander of the STS-135 mission that will soon close out NASA’s Space Shuttle Era.

Chris talked to me about his childhood experiences that led him to “love science” and how he strongly believes in “giving back” to a community that enriched him so much – and eventually led him to his career as a space shuttle astronaut.

That passion for science and giving will result in an extraordinary and out of this world gift to the people of Philadelphia, Pennsylvania, hometown to Chris Ferguson that he hopes will inspire kids to love science.

I first met Chris about two years ago in Philadelphia when he generously gave a well received presentation to our astronomy club, the Rittenhouse Astronomical Society – which meets at the Franklin Institute Science Museum and where I frequently lecture too.

At that time Ferguson had already been a veteran space flyer with two trips to the International Space Station – but he not yet been named to command the last shuttle flight. Over 150 folks attended Ferguson’s talk – held in the presence of the marble statue of Benjamin Franklin. The statue is a US National Historic Landmark.

As a child, Chris attended classes from grade school to high school in Philadelphia, the city of brotherly love.

“I developed and cultivated a love of science, engineering and space in many childhood trips to the Franklin Institute in Philadelphia,” Ferguson told me.

“I was always a science oriented kid growing up. I have an innate curiosity for how things work. The Franklin Institute fed my curiosity.”

“And it was some teachers I had at a young age in my high school in Philadelphia who made me want to understand more. And to understand the reason about why things work the way they do … And to understand why the physical laws that govern the Universe are the way they are.”

“The one thing I could never fathom well was understanding spaceflight. And the way to really understand something is to go do it,” said Chris Ferguson.

“What this is really about is going into space, living and working there and dragging the American public along with us. We need to constantly feed the machine for the folks who are curious and are on a quest to understand things they don’t understand and desire to wonder what’s beyond low Earth orbit and how you live in space for a long period of time.”

“The only way you feed that is by planting the seeds when they are young. You grow the big Oaks out of little acorns.”

“And you get the little acorns at places like the Franklin Institute and the Smithsonian National Air & Space Museum. That’s what did it for me,”

“I think you need to go back and you need to give back. So I’m looking forward to going back to the Franklin Institute !” said Ferguson

And when Chris does go back to the Franklin Institute later this year he will bring along a very very special gift – a piece of the Institute’s Fels Planetarium dome flew millions of miles to the space station and back aboard history’s very last Space Shuttle orbiter – Atlantis – that will ever take a star trek to the High Frontier.

And the project was Ferguson’s idea according to Derrick Pitts, Chief Astronomer at the Fels Planetarium of the Franklin Institute.

“Chris sent me an email asking if we (The Franklin Institute) would like to fly something on STS-135,” Pitts told me.

“I quickly agreed, found out what the criteria for launch would be and then pulled a team together to figure out what to send. It was decided to send a star-shaped piece of the original Fels Planetarium dome.

“The original dome was replaced in 2002 but I’d kept several large sections of the stainless steel panels and had a number of 5-pointed stars about 4″ across cut from the panels to mount and give as gifts to friends of the Fels. It weighs about 6 oz.”

“Since more than 10 million visitors have sat under that dome including several school students who would later become NASA astronauts, it seemed fitting to send one of these stars.”

“The piece presented some problems though. As a stainless steel piece, it has sharp edges and 5 very sharp points – both verboten by NASA and it is ever so slightly oversized. We fixed the worst problem by encasing the star – points edges and all – in a transparent acrylic ‘jewel box’ sandwich held closed with stainless steel screws.”

“We had about ten days from the first email to delivery date to him in Houston. When it returns to Earth, Ferguson has offered to bring it back to Philadelphia where we’ll put it on permanent display in the main Planetarium hallway. This will be the second time Franklin has flown an article with a native Philadelphian astronaut. Our last trip was with Jim Bagian on STS-40 in 1991.”

Chris is a humble, eloquent and down to earth guy and knows how lucky he is to be commanding the grand finale of the thirty year long shuttle program. And he is determined that he and his STS-135 crew of four do their very best to accomplish all their goals.

“I’m just proud to be a small part of it and am savoring the moment. We’re focused on the mission now and will have time to ponder this moment in history when it’s all over,” Ferguson concluded.

Space Shuttle Atlantis and her crew of 4 are scheduled to land at 5:56 a.m. on July 21, 2011 at the Kennedy Space Center in Florida.

First Ever Vesta Vistas from Orbit – in 2D and 3D

Enhanced - First Vesta Vista Captured in orbit by Dawn on July 17, 2011. This image taken by the framing camera on July 17, 2011 has been enhanced to bringouitr further detail. It was taken from a distance of about 9,500 miles (15,000 kilometers) away from the protoplanet Vesta. Each pixel in the image corresponds to roughly 0.88 miles (1.4 kilometers).

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.”

ULA Inks Deal With NASA To Study Man-Rating Atlas V

United Launch Alliance and NASA signed into am agreement to research the viability of having the Atlas V rocket potentially be used as a launch vehicle for astronauts. Photo Credit: Alan Walters/awaltersphoto.com

CAPE CANAVERAL Fla. — NASA is looking for a few good rockets – that’s right, plural. While it continues to review the Space Launch System or SLS – it has inked a non-funded agreement with United Launch Alliance (ULA) to utilize the Denver-based firm’s Atlas V rockets to send astronauts into orbit. The announcement was made at Kennedy Space Center in Florida on Monday.

The Space Act Agreement signed by the space agency and ULA will see critical information regarding the flight characteristics of the Atlas V be provided to NASA. ULA will not be alone in providing information however; NASA will give ULA vital data regarding its experience sending humans into orbit as well as guidance as how to adapt the Atlas V for human space flight purposes. NASA will help ULA with both the crew transportation system capabilities as well as the human certification requirements.

This will begin a process where ULA and NASA will work closely with one another to guide the Atlas V toward being man-rated. Before that can happen there are numerous pertinent issues that have to be reviewed first, such as the cost involved and other issues involved with the certification process.

The Atlas V is an expendable launch vehicle that has not only been used by NASA, but the Department of Defense (DoD) as well. The Atlas’ proven track record should allow a large portion of the study to be completed before the end of this year.

NASA’s part of the arrangement includes providing milestone briefings and technical reviews to check and see how the project is progressing as well as identifying risks and attempting to mitigate them.

ULA meanwhile will use its own funds to pay for the Crew Transportation System (CTS). Design maturation, required analyses (including hazard reviews that are unique to human space flight efforts) as well as establishing a man-rated baseline for the Atlas V all will be handled by United Launch Alliance.

The rationale behind why the Atlas V was specifically selected is simple, both Sierra Nevada Corporation and Blue Origin’s proposals under the Commercial Crew Development – 02 (CCDev-02) contract – utilize the Atlas V. Bigelow Aerospace has also looked at the rocket as a launch service provider.

“I am truly excited about the addition of ULA to NASA’s Commercial Crew development Program team,” said NASA Administrator Charles Bolden. “Having ULA on board may speed the development of a commercial crew transportation system for the International Space Station, allowing NASA to concentrate its resources on exploring beyond low
Earth orbit.”

The Atlas V has had 26 consecutive successful flights, making it an easily one of the front runners to potentially send astronauts to orbit.

“We believe this effort will demonstrate to NASA that our systems are fully compliant with NASA requirements for human spaceflight,” said George Sowers, ULA’s vice president of business development. “ULA looks forward to continued work with NASA to develop a U.S. commercial crew space transportation capability providing safe,
reliable, and cost effective access to and return from low Earth orbit and the International Space Station.”

Happy 90th Birthday John Glenn!

He’s an American space icon, and today he turns 90 years of age. “John Glenn is a legend, and NASA sends him our best wishes on this major personal milestone,” NASA Administrator Charles Bolden said in a statement. John’s legacy and contributions to the continued progress of human spaceflight are immense. His example is one we continue to emulate as we push toward farther destinations in the solar system.”

What better way to look back a Glenn’s achievements than this 1963 NASA video, found in the National Archives Repository.

CAPE CANAVERAL Fla. – Garrett Reisman knows a thing or two about what it takes to send astronauts to orbit. He should, he has taken the trip himself – twice. Reisman spent three months on the International Space Station launching with the STS-123 crew, and was a Mission Specialist on STS-132. He has walked in space, operated Canada’s Dextre robot and installed critical flight hardware to the ISS.

He has since left NASA to work for Space Exploration Technologies (SpaceX). Reisman took a moment to chat with Universe Today just before the final launch of the shuttle program, STS-135, on the orbiter Atlantis. Reisman spoke about SpaceX’s contract with NASA under the second phase of the Commercial Crew Development contract or CCDev-02, his new role as Director of SpaceX’s Dragon Rider program and whether there is another trip to space in his future.

Universe Today: Hi Garrett, thanks for taking the time to talk with us today, tell us a little about CCDev-02.

Reisman: “Thanks, it’s good to be here, SpaceX has dubbed CCDev-02 the ‘Dragon Rider’ program, CCDev sounds like someone’s logon name. Dragon Rider is the name of SpaceX’s efforts to send astronauts into orbit on board the Dragon Spacecraft.”

Universe Today: A nod to Anne McCaffrey’s Dragonriders of Pern?

Reisman: “Exactly!” (laughing)

Universe Today: If you had to pick out one of the most interesting elements of what SpaceX is working on for CCDev-02 – what would it be?

Reisman: “I think I would have to say it is the integrated launch abort system. The system that SpaceX is working on will not be the normal tower that is positioned above the spacecraft; instead it will be built into the sides of the Dragon. This system will be reusable and allow the Dragon to land.”

Universe Today: What do you think sets SpaceX apart from other, similar companies?

Reisman: “Some companies will offer you the rocket, others the spacecraft, at SpaceX we got both – it’s one-stop-shopping. We got the rocket, the Falcon 9, which has had two very successful test flights and we have the Dragon Spacecraft which became the first commercial spacecraft to orbit the Earth and splash down safely this past December. With both of these vital elements we have great confidence that we can do what we say we will do as we move forward.”

Universe Today: What made you decide to leave NASA and come to SpaceX?

Reisman: “I left NASA about four months ago and came over to SpaceX because I was very excited about what was going on in the commercial sector, just all this amazing innovation that was being unleashed and I wanted to be a part of that, to contribute to that.”

Universe Today: Final question, as a veteran astronaut are you hoping to ride Dragon to orbit one day?

Reisman: (smiles) While that’s not why I joined SpaceX – I wouldn’t rule it out either…”

SpaceX is looking to launch the next Falcon 9 rocket with Dragon Spacecraft some time this fall from Cape Canaveral Air Force Station’s Launch Complex 40. This demonstration flight will test out the Dragon’s navigation and other operating systems. This year SpaceX is planning to launch two flights under the Commercial Orbital Transportation Services or COTS contract, worth $1.6 billion, that the company has with NASA.

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. It was taken from a distance of about 26,000 miles (41,000 kilometers) away from the protoplanet Vesta. Each pixel in the image corresponds to roughly 2.4 miles (3.8 kilometers).

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.

Two Days of Tweetness: Witnessing a Shuttle Launch

Space Tweeps Unite! NASA Tweetup participants gather at the launch clock on Friday, July 8, 2011. © NASA HQ Photo

It’s been over a week since the NASA Tweetup and I’m still thinking about it. For good reason, of course… it was awesome.

Over the course of two days I saw a capsule that had been to space and back, talked with five astronauts (one currently in orbit!), toured Kennedy Space Center, met a muppet, touched a piece of the Moon, made dozens of new friends and, of course, watched, heard and felt the launch of the last space shuttle to leave Earth. (And managed to talk my way into a delicious barbecue sandwich inside the Vehicle Assembly Building.) All with less than six hours of sleep.

Not too shabby. 😉
