After a lengthy hiatus, the workhorse Delta II rocket that first launched a quarter of a century ago and placed numerous renowned NASA science missions into Earth orbit and interplanetary space, as well as lofting dozens of commercial and DOD missions, is about to soar again this week on July 1 with NASA’s Orbiting Carbon Observatory-2 (OCO-2) sniffer to study atmospheric carbon dioxide (CO2).

OCO-2 is NASA’s first mission dedicated to studying atmospheric carbon dioxide, the leading human-produced greenhouse gas and the principal human-produced driver of climate change.

The 999 pound (454 kilogram) observatory is equipped with one science instrument consisting of three high-resolution, near-infrared spectrometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change.

The $467.7 million OCO-2 mission is set to blastoff atop the United Launch Alliance (ULA) Delta II rocket on Tuesday, July 1 from Space Launch Complex 2 at Vandenberg Air Force Base in California.

Liftoff is slated for 5:56 a.m. EDT (2:56 a.m. PDT) at the opening of a short 30-second launch window.

NASA TV will broadcast the launch live with countdown commentary beginning at 3:45 a.m. EDT (12:45 a.m. PDT): http://www.nasa.gov/multimedia/nasatv/

The California weather prognosis is currently outstanding at 100 percent ‘GO’ for favorable weather conditions at launch time.

The two stage Delta II 7320-10 launch vehicle is 8 ft in diameter and approximately 128 ft tall. It is equipped with a trio of strap on solid rocket motors. This marks the 152nd Delta II launch overall and the 51st for NASA since 1989.

The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.

The final Delta II launch from Cape Canaveral on Sept. 10, 2011 boosted NASA’s twin GRAIL gravity mapping probes to the Moon.

The Delta II will boost OCO-2 into a 438-mile (705-kilometer) altitude, near-polar orbit. Spacecraft separation from the rocket occurs 56 minutes 15 seconds after launch.

It will lead a constellation of five other international Earth monitoring satellites that circle Earth.

The phone-booth sized OCO-2 was built by Orbital Sciences and is a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly.

OCO-2 is the second of NASA’s five new Earth science missions launching in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

Orbiting Carbon Observatory-2 (OCO-2) mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA..

“Carbon dioxide in the atmosphere plays a critical role in our planet’s energy balance and is a key factor in understanding how our climate is changing,” said Michael Freilich, director of NASA’s Earth Science Division in Washington.

“With the OCO-2 mission, NASA will be contributing an important new source of global observations to the scientific challenge of better understanding our Earth and its future.”

It will record around 100,000 CO2 measurements around the world every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.

At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.

NASA’s Orion Deep Space Capsule Completes Most Complex Parachute Test Ahead of Maiden Launch

A test version of NASA’s Orion deep space capsule has completed its most complex and last full flight-like parachute drop test on June 25 ahead of the maiden launch on the EFT-1 mission now slated for early December 2014.

The descent test was conducted at an altitude of 35,000 feet over the Arizona desert at the U.S. Army’s Yuma Proving Ground by pulling the test vehicle out of a huge C-17 cargo aircraft.

The test also included the addition of several added stress tests to check out the ability of the parachute system to compensate and examine capsule and astronaut crew survival via several potential failure modes.

For example, engineers rigged one of the main parachutes to skip the intermediate phase of the three-phase process to unfurl each of Orion’s three parachutes, called reefing.

“This tested whether one of the main parachutes could go directly from opening a little to being fully open without an intermediary step, proving the system can tolerate potential failures,” according to NASA.

The goal is to prove that that parachute system will slow Orion to ensure a safe landing speed for the astronaut crews returning from deep space missions to the Moon, Asteroids and eventually Mars.

“We’ve put the parachutes through their paces in ground and airdrop testing in just about every conceivable way before we begin sending them into space on Exploration Flight Test (EFT)-1 before the year’s done,” said Orion Program Manager Mark Geyer in a state

“The series of tests has proven the system and will help ensure crew and mission safety for our astronauts in the future.”

Orion is slated to launch on its inaugural unmanned EFT-1 test flight in December 2014 atop the mammoth, triple barreled United Launch Alliance (ULA) Delta IV Heavy rocket from Cape Canaveral, Florida.

This test also marked the last time that the entire parachute sequence involving the deployment of all three 116 foot-wide main chutes will be tested before the December launch.

For some of the parachutes, this was the highest altitude drop test attempted.

“Engineers also put additional stresses on the parachutes by allowing the test version of Orion to free fall for 10 seconds, which increased the vehicle’s speed and aerodynamic pressure,” NASA noted in a statement.

The parachute deployment and unfurling can only begin after jettisoning of the spacecraft’s forward bay cover. The chutes are housed below the cover which protects the chutes until reentry into Earth’s atmosphere.

The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

One of the primary goals of NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight is to test the efficacy of the heat shield in protecting the vehicle – and future human astronauts – from excruciating temperatures reaching 4000 degrees Fahrenheit (2200 C) during scorching re-entry heating.

At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).

“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.

The parachute system comprising of two drogue parachutes and a trio of main parachutes – nearly the size of a football field – will then unfurl to slow Orion down to just 20 mph for a safe splashdown and recovery by the US Navy in the Pacific Ocean.

The Orion EFT-1 mission will end with a splashdown in the Pacific Ocean. During the stationary recovery test of Orion at Norfolk Naval Base on Aug. 15, 2013, US Navy divers attached tow lines and led the test capsule to a flooded well deck on the USS Arlington. Credit: Ken Kremer/kenkremer.com.

Another drop test scheduled for August will test the combined failure of one drogue parachute and one main parachute, as well as new parachute design features, says NASA.

Meanwhile, Orion’s prime contractor Lockheed Martin is finishing assembly and test operations of the EFT-1 capsule inside the Operations and Checkout Facility (O & C) at the Kennedy Space Center (KSC) flying in December’s launch

Curiosity Marks Milestone Anniversary – 1 Martian Year On Mars!

NASA’s Curiosity rover celebrated a milestone anniversary today, June 24 – 1 Martian Year on Mars!

A Martian year is equivalent to 687 Earth days, or nearly two Earth years.

NASA marked the illustrious achievement with the release of a new ‘selfie’ captured recently while drilling deep into the Red Planet to unlock the secrets of Mars hidden past eons ago when the planet was far warmer and wetter and more conducive to the origin of life.

Curiosity’s new self-portrait was taken at the ‘Windjana’ Drilling Site in April and May 2014 using the Mars Hand Lens Imager (MAHLI) camera at the end of the robotic arm.

As of today the 1 ton rover has been exploring the alien surface for a full Martian year since her nail biting touchdown inside Gale Crater on Aug. 5, 2012 – using the unprecedented sky crane maneuver which culminated in a rocket assisted touchdown astride a humongous mountain named Mount Sharp.

Mount Sharp dominates the center of Gale Crater and reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Rainier.

During Mars Year 1 on Mars, Earth’s metallic emissary has already accomplished her primary objective of discovering a habitable zone on the Red Planet that contains the chemical ingredients necessary to support microbial life in the ancient past.

During 2013, Curiosity conducted the first two drill campaigns at the ‘John Klein’ and ‘Cumberland’ outcrop targets inside Yellowknife Bay. They were both mudstone rock outcrops and the interiors were markedly different in color and much lighter compared to the new drill site at ‘Windjana’ into a slab of red, sandstone rock.

The fresh bore hole was drilled into the “Windjana” rock outcrop on May 5, 2014, Sol 621, at the base of Mount Remarkable at a science stopping point called “The Kimberley Waypoint.”

It was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity has successfully delivered pulverized and sieved samples from all three drill sites to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

It was through the results of the SAM and CheMin analysis and the discovery of clay minerals that the science team was able to determine that this area on the floor of Gale Crater is a habitable zone.

“Windjana has more magnetite than previous samples we’ve analyzed,” said David Blake, principal investigator for Curiosity’s Chemistry and Mineralogy (CheMin) instrument at NASA’s Ames Research Center, Moffett Field, California, in a statement.

“A key question is whether this magnetite is a component of the original basalt or resulted from later processes, such as would happen in water-soaked basaltic sediments. The answer is important to our understanding of habitability and the nature of the early-Mars environment.”

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The lower reaches of Mount Sharp are the rovers ultimate goal because the sedimentary layers are believed to hold caches of water altered minerals based on high resolution measurements obtained by the CRISM spectrometer aboard NASA’s powerful Martian ‘Spysat’ – the Mars Reconnaissance Orbiter (MRO) – soaring overhead.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

‘Time Capsule On Mars’ Team Hopes To Send a Spacecraft There With Your Messages

It’s an ambitious goal: land three Cubesats on Mars sometime in the next few years for $25 million. And all this from a student-led team.

But the group, led by Duke University, is dutifully assembling sponsors and potential in-kind contributions from universities and companies to try to reach that goal. So far they have raised more than half a million dollars.

“We were thinking that something was missing,” said Emily Briere, the student team project lead who attends Duke University, explaining how it seemed few Mars missions were being done for the benefit of humanity in general.

“We want to get the whole world excited about space exploration, and why we go to space in the first place, which was to push forward mankind and to build new habitats,” she added. Prime among their objectives is to drive engagement in the kindergarten to Grade 12 audience by encouraging them to submit photos and videos to send to Mars.

But that said, everyone can participate! The official launch of the project is today, and you can read more details about the crowdfunding campaign and how to get involved on the Time Capsule to Mars website. Contributions start at only a dollar, where you can send your picture to Mars. The spacecraft will be loaded with audio, video and text messages from Earth.

“Each satellite will contain a terabyte of data that will act as a digital ‘time capsule’ carrying messages, photos, audio clips and video contributed by tens of millions of people from all over the globe,” says the Time Capsule to Mars team. “The capsule will remain a vessel of captured moments of today’s human race on Earth in 2014, to be rediscovered by future colonists of the Red Planet.”

The team hopes to use ion electric propulsion to get their small spacecraft to the Red Planet. It would head to space itself on a secondary payload on a rocket. (Briere couldn’t disclose who they are talking to, but said ideally it would happen within the next two years.)

Some of the corporate sponsors including Boeing, Lockheed Martin and Aerojet while students come from universities such as Stanford, Duke and the Massachusetts Institute of Technology.

Driving, Driving, Driving – Curiosity’s Top Priority on the Road to Mysterious Mount Sharp

Driving, Driving, Driving – that’s the number one priority for NASA’s rover Curiosity as she traverses across the floor of Gale Crater towards towering Mount Sharp on an expedition in search of the chemical ingredients of life that could support Martian microbes if they ever existed.

See our photo mosaics above and below showing the 1 ton rover trundling across the alien terrain of Mars – our Solar Systems most Earth-like planet and leaving behind dramatic wheel tracks in her wake.

“The top priority for MSL continues to be the traverse toward the base of Mt. Sharp,” wrote science team member Ken Herkenhoff in a mission update.

Curiosity has been on the move since mid-May after successfully completing her 3rd Martian drill campaign at a science stopping point called “The Kimberley” where she bored a fresh hole into the ‘Windjama’ rock target on May 5, Sol 621 at the base of Mount Remarkable.

“Progress has been good since leaving The Kimberley,” Herkenhoff added.

Investigating mysterious Mount Sharp is why Gale Crater was chosen as the landing site because the mountain holds clues to the habitability of the Red Planet.

Mars was far wetter and warmer – and more conducive to the origin of life – billions of years ago.

The six-wheeled rover has been traveling with all deliberate speed to get to the mountain with minimal science along the way.

“[Curiosity conducted] a 129-meter drive on Sol 662 (June 17),” says Herkenhoff.

“We successfully planned a rapid traverse sol last week, in which scientific observations are limited in favor of maximizing drive distance.”

Curiosity is driving on a path towards the ‘Murray Buttes’ – which lies across the dark and potentially treacherous dunes on the right side of Mount Sharp as seen in our photo mosaic above from Sol 651.

She will eventually ascend the mountain at the ‘Murray Buttes’ after the team locates a spot to carefully cross the sand dunes.

The fresh hole drilled into “Windjana” was 0.63 inch (1.6 centimeters) in diameter and about 2.6 inches (6.5 centimeters) deep and resulted in a mound of dark grey colored drill tailings piled around. It looked different from the initial two holes drilled at Yellowknife Bay in the spring of 2013.

Windjana was a cold red slab of enticing bumpy textures of Martian sandstone located at the base of ‘Mount Remarkable’ within the “The Kimberley Waypoint” region.

The first two drill campaigns involved boring into mudstone outcrops at Yellowknife Bay.

Windjana lies some 2.5 miles (4 kilometers) southwest of Yellowknife Bay.

Curiosity then successfully delivered pulverized and sieved samples to the pair of onboard miniaturized chemistry labs; the Chemistry and Mineralogy instrument (CheMin) and the Sample Analysis at Mars instrument (SAM) – for chemical and compositional analysis.

Chemical analysis and further sample deliveries are in progress as NASA’s rover is ‘on the go’ to simultaneously maximize movement and research activities.

The science and engineering team has deliberately altered the robots path towards the foothills of Mount Sharp which reaches 3.4 miles (5.5 km) into the Martian sky – taller than Mount Ranier.

The team decided to follow a new path to the mountain with smoother terrain after sharp edged rocks caused significant damage in the form of dents and holes to the robots 20 inch wide aluminum wheels.

The wheel punctures happened faster than expected in 2013 and earlier this year.

Curiosity still has about another 2.4 miles (3.9 kilometers) to go to reach the entry way at a gap in the dunes at the foothills of Mount Sharp sometime later this year.

India’s 1st Mars Mission Celebrates 100 Days and 100 Million Kilometers from Mars Orbit Insertion Firing – Cruising Right behind NASA’s MAVEN

India’s inaugural voyager to the Red Planet, the Mars Orbiter Mission or MOM, has just celebrated 100 days and 100 million kilometers out from Mars on June 16, until the crucial Mars Orbital Insertion (MOI) engine firing that will culminate in a historic rendezvous on September 24, 2014.

MOM is cruising right behind NASA’s MAVEN orbiter which celebrated 100 days out from Mars on Friday the 13th of June. MAVEN arrives about 48 hours ahead of MOM on September 21, 2014.

After streaking through space for some ten and a half months, the 1,350 kilogram (2,980 pound) MOM probe will fire its 440 Newton liquid fueled main engine to brake into orbit around the Red Planet on September 24, 2014 – where she will study the atmosphere and sniff for signals of methane.

Working together, MOM and MAVEN will revolutionize our understanding of Mars atmosphere, dramatic climatic history and potential for habitability.

The do or die MOI burn on September 24, 2014 places MOM into an 377 km x 80,000 km elliptical orbit around Mars.

Trans Mars Injection (TMI), carried out on Dec 01, 2013 at 00:49 hrs (IST) has moved the spacecraft in the Mars Transfer Trajectory (MTT). With TMI the Earth orbiting phase of the spacecraft ended and the spacecraft is now on a course to encounter Mars after a journey of about 10 months around the Sun. Credit: ISRO

MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s maiden foray into interplanetary flight.

But before reaching Mars, mission navigators must keep the craft meticulously on course on its heliocentric trajectory from Earth to Mars through a series of in flight Trajectory Correction Maneuvers (TMSs).

The second TCM was just successfully performed on June 11 by firing the spacecraft’s 22 Newton thrusters for a duration of 16 seconds. TCM-1 was conducted on December 11, 2013 by firing the 22 Newton Thrusters for 40.5 seconds. Two additional TCM firings are planned in August and September 2014.

To date the probe has flown about 70% of the way to Mars, traveling about 466 million kilometers out of a total of 680 million kilometers (400 million miles) overall, with about 95 days to go. One way radio signals to Earth take approximately 340 seconds.

MOM reached the halfway mark to Mars on April 9, 2014.

ISRO reports the spacecraft and its five science instruments are healthy. It is being continuously monitored by the Indian Deep Space Network (IDSN) and NASA JPL’s Deep Space Network (DSN).

MOM’s journey began with a picture perfect blast off on Nov. 5, 2013 from India’s spaceport at the Satish Dhawan Space Centre, Sriharikota, atop the nations indigenous four stage Polar Satellite Launch Vehicle (PSLV) which placed the probe into its initial Earth parking orbit.

A series of six subsequent orbit raising maneuvers ultimately culminated with a liquid fueled main engine firing on Dec. 1, 2013 for the Trans Mars Injection(TMI) maneuver that successfully placed MOM on a heliocentric elliptical trajectory to the Red Planet.

If all goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

Together, MOM and MAVEN will fortify Earth’s invasion fleet at Mars. They join 3 current orbiters from NASA and ESA as well as NASA’s pair of sister surface rovers Curiosity and Opportunity.

Although they were developed independently and have different suites of scientific instruments, the MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist told Universe Today.

“We have had some discussions with their science team, and there are some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

“At the point where we [MAVEN and MOM] are both in orbit collecting data we do plan to collaborate and work together with the data jointly,” Jakosky said.

Stay tuned here for Ken’s continuing MOM, MAVEN, Opportunity, Curiosity, Mars rover and more planetary and human spaceflight news.

See This Orange Smudge? This Could Be NASA’s Target For The Asteroid Mission

In the center of the image above is an orange smudge. It may not look like much to the untrained eye, but to NASA it represents potential. It’s a candidate asteroid target for a mission the agency badly wants to happen, even though nobody knows for sure yet if things will line up for humans to visit there one day.

This is a picture of asteroid 2011 MD taken by NASA’s Spitzer Space Telescope. It’s about 6 meters (20 feet) across and appears to have a low density, the agency said in a statement. While NASA is still looking for other candidates for its asteroid initiative, the agency added this would be the sort of asteroid it’s looking to visit.

“The asteroid appears to have a structure perhaps resembling a pile of rocks, or a ‘rubble pile.’Since solid rock is about three times as dense as water, this suggests about two-thirds of the asteroid must be empty space,” NASA stated in this press release.

“The research team behind the observation says the asteroid could be a collection of small rocks, held loosely together by gravity, or it may be one solid rock with a surrounding halo of small particles.”

You can read more about this asteroid in Astrophysical Journal Letters. There was another study done on 2011 MD earlier this year that was also in ApJL, or in preprint version in Arxiv.

Announcing this asteroid candidate was just one of several things NASA made public today. It added that it plans to send off an ARM (Asteroid Redirect Mission) robotic spacecraft in 2019, and about one year before that it will decide which asteroid to send this spacecraft to.

NASA has two concept ideas for ARM, and it’s planning to award $4.9 million (it had initially planned for up to $6 million) for others to make more detailed investigations into which is the more feasible. Read the full list of recipients at this NASA website.

One idea is to pick up a small asteroid, and the other is to carve off a small portion of a bigger asteroid. Whatever the choice, it would involve coming up with an object that is less than 32 feet (10 meters) across to move to the moon’s orbit. NASA will decide what to do later this year.

“The studies will be completed over a six-month period beginning in July, during which time system concepts and key technologies needed for ARM will be refined and matured. The studies also will include an assessment of the feasibility of potential commercial partners to support the robotic mission,” NASA stated.

Also, some more details about other candidates: NASA has found nine so far that it deems suitable, and size estimates have been made on three of those nine candidates. A fourth, 2008 HU4, will be close to Earth in 2016 and allow for “interplanetary radar” to learn more about its size and rotation, NASA said. The other ones will not get close enough to Earth for a better look before the mission selection is done.

NASA added that it expects to add more through its Near-Earth Object program, as one to two asteroids get close enough to our planet every year for analysis. Further, the agency hopes to learn more about asteroid makeup through its planned Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) mission, which is on its way to asteroid Bennu in 2018 after a launch in 2016.

All of this, of course, is dependent on NASA’s budgetary situation for the years to come, which in turn depends on support in Congress.

What Will Rosetta’s Comet Look Like? How Artists Over The Years Pictured It

Comets are notoriously hard to predict — just ask those people on Comet ISON watch late in 2013. So as Rosetta approaches its cometary target, no one really knows what the comet will look like from up close. Yes, there are pictures of other cometary nuclei (most famously, Halley’s Comet) but this one could look completely different.

Several artists have taken a stab at imagining what Rosetta will see when it gets close to the comet in August, and what Philae will touch on when it reaches the surface in November. You can see their work throughout this article.

Meanwhile, the European Space Agency just issued an update on what they can see of 67P/Churyumov–Gerasimenko from half a million km away — the comet is quieter, they said.

“Strikingly, there is no longer any sign of the extended dust cloud that was seen developing around nucleus at the end of April and into May,” ESA stated in a press release. “Indeed, monitoring of the comet has shown a significant drop in its brightness since then.”

This variability is common in comets, but it’s the first time it’s been seen from so close, ESA said. Comets warm up as they approach the sun, releasing ice, gas and dust that form a swarm of material.

“As comets are non-spherical and lumpy, this process is often unpredictable, with activity waxing and waning as they warm. The observations made over the six weeks from the end of April to early June show just how quickly the conditions at a comet can change,” ESA added.

Elon Musk: ‘I’m Hopeful That The First People Can Be Taken To Mars in 10, 12 Years’

Elon Musk, CEO of SpaceX, is a hot topic in the media these days. He recently unveiled a manned version of his successful Dragon spacecraft. He’s talking about retrieving the first stage of his Falcon 9 rocket, a feat that has never been accomplished.

Last night (June 18), Musk spoke on CNBC because his company was named #1 to the cable network’s second annual Disrupter 50 list. You can watch portions of the interview here and we’ve isolated the space-related parts below based on the transcript from CNBC (which does not exactly match Musk’s words, but is pretty close.)

And Musk is still a big fan of Mars exploration, as he says in the interview he hopes to see people walk on the planet in 10-12 years.

On attempting to recover the first stage of the Falcon 9 rocket that will launch six Orbcomm satellites on Friday, if the weather holds (it is only 30% go according to local news reports):

Essentially what I was alluding to a moment ago was is to be able to recover the rocket booster and then refly it. That’s the revolutionary potential. Now we have been trying to do that for 12 years, and haven’t yet succeeded. But I feel as though we are finally close to achieving it. We have a shot with the next launch of recovering the rocket booster. If not with this launch, I think a very good chance later this year, and then potentially to refly the booster next year. This would really mark a significant change in the technology of rocketry.

Musck also spoke on what would happen if SpaceX does not get the next round of commercial crew funding from NASA. The company is right now being funded along with Boeing (CST-100) and Sierra Nevada (Dream Chaser), but NASA is still figuring out how many companies it can afford to back in the next stage, which will be announced later this year. Musk revealed the manned prototype version of its Dragon spacecraft to great media fanfare in late May.

First of all, I should acknowledge the critical role NASA played in the success of SpaceX. We wouldn’t be are where we are without the help of NASA. And it’s possible we may not win the commercial crew contract. We certainly have done that we can for our part. And I think we have got a great design solution. If NASA in the end doesn’t go with us, because also we are competing with big established companies like Boeing, then we’ll do our best to continue on our own with our own money. […]

Well it definitely would slow us down, but we would keep going and we should keep launching commercial satellites. We have an existing contract to transfer…from the space station so we would keep going. It just would be slower.

Musk on how quickly he wants to see humans on Mars:

This is a very difficult thing, obviously. I’m hopeful that the first people could be taken to Mars in 10, 12 years. I think it’s certainly possible for that to occur. The thing that matters long term is to have a self-sustaining city on Mars. To make life multi-planetary. That will define a fundamental bifurcation of the future of human civilization. We’ll either be a multi-planet species and out there among the stars, or a single-planet species until some eventual extinction event, natural or man-made.

Why it’s difficult to get public funding right now:

The incentive structure tends to be short-term. You can trace it back to people that own the stocks, portfolio managers. They are evaluated on a quarterly basis, or at least an annual basis. They push companies to produce results on a quarterly or annual basis. With SpaceX we are trying to develop technology that will ultimately be able to take large numbers of people to Mars. That’s really difficult to get portfolio managers. It’s beyond their tenure in owning the stock. So it is difficult to ask them to like that.

Which is harder, getting people to Mars or building a car battery that costs less than $5,000 (which is an oblique reference to Musk’s Tesla line of vehicles):

I think, probably, Mars. The car battery certainly is hard. I’m quite optimistic, though, about improvements in the battery price or the cost of the battery. The fundamental cost. We have daily meetings with Panasonic, our key development partner, on this. I am really feeling quite good about being able to produce a compelling mass market car in about three years.

What would be a “truly disruptive” technology:

I mean, at this point, human life span is mostly about old age. It’s not about cancer or anything else. If you cured cancer, I think the average life expectancy would increase from two years. You would go from 80 to 82, or something like that. We just have a genetic life span. It’s kind of like if you take a fruit fly and gave it the best exercise and diet possible, the perfect life. Maybe it will live four weeks instead of three weeks. Genetics just drives a lot of these things. So for something to be truly disruptive on that front, you would want to do something with genetics. I don’t have much involvement there. Or any involvement, really.

Where To Go After Pluto? Hubble Seeks The Next Target For New Horizons

It’s going to be a really busy summer for the New Horizons team. While they’re checking out the newly awakened spacecraft to make sure it’s working properly for its close encounter with Pluto next year, NASA is already thinking about where to put it next: possibly towards a Kuiper Belt Object!

So now the Hubble Space Telescope (in Earth orbit) is scoping out icy objects beyond Pluto. Luckily for us, one of the team members — Alex Parker, a planetary astronomer at the University of California, Berkeley, provided an entertaining livetweet of the process — even through a power failure.

So, the secret is out. On Friday, we were awarded the Hubble time to search for a @NewHorizons2015 KBO target!

— Alex Parker (@Alex_Parker) June 16, 2014

This is an extremely quick-turnaround survey. The first observations hit the ground this morning and our team is about to process them.

— Alex Parker (@Alex_Parker) June 16, 2014

Right now there is a robot in space searching the fringes of our solar system for an icy world that another robot will visit in a few years.

— Alex Parker (@Alex_Parker) June 16, 2014

I have seen the first of the Hubble data, and it is beautiful.

— Alex Parker (@Alex_Parker) June 16, 2014

Here’s the first raw Hubble image from our KBO search. We should have our first clean stacks by the end of the day. pic.twitter.com/3FNSgDHL4M

— Alex Parker (@Alex_Parker) June 16, 2014

There’s far more to Parker’s tweets than we are indicating here; his Twitter feed also has details about the collaborators, for example, so be sure to read through the entire exchange from yesterday. The survey is led by the Southwest Research Institute’s John Spencer.

What astronomers are doing now is a “pilot observation” where the space telescope looks at a spot in the constellation Sagittarius. Controllers will try to turn the telescope at the same rate as what a KBO would be orbiting around the sun. If the method works, stars will look like streaks and the KBOs will look like “pinpoint objects”, NASA stated.

“If the test observation identifies at least two KBOs of a specified brightness it will demonstrate statistically that Hubble has a chance of finding an appropriate KBO for New Horizons to visit. At that point, an additional allotment of observing time will continue the search across a field of view roughly the angular size of the full moon,” NASA said in a press release.

The reason for this step is Hubble is a high-profile telescope, receiving a lot of requests for observing time around the world. The agency wants to ensure that the telescope is being used for the best scientific return possible. NASA also noted the search might be difficult.

“Though Hubble is powerful enough to see galaxies near the horizon of the universe, finding a KBO is a challenging needle-in-haystack search. A typical KBO along the New Horizons trajectory may be no larger than Manhattan Island and as black as charcoal,” NASA stated.

This isn’t the first time the telescope has done a pinch-hit for Plutonian science. Four new moons have been found around Pluto, a discovery that involved Hubble time. The telescope has also looked for dust rings near the dwarf planet (to do a risk analysis for New Horizons’ approach) and done a map of the surface, to help controllers figure out where to target New Horizons.
