Is that the smell of rocket fuel in the air, or customer excitement?
The reported 600+ customers waiting in line for a trip to space aboard SpaceShipTwo (nickname: Enterprise) surely must have been excited when the suborbital spaceship successfully sailed through another powered flight test today (Thursday).
“SS2 has successfully completed another supersonic rocket-powered test flight! Hit our planned duration, altitude, and speed,” Virgin Galactic wrote on Twitter.
Watch the video of the flight below:
SpaceShipTwo also tested a “feathering” system that it has on board to assist with controlled re-entry. It allows the entire tail of the spaceship to rotate up to about 65 degrees, which Virgin says allows fine control of the attitude as the spacecraft comes back to Earth. “The feather configuration is also highly stable, effectively giving the pilot a hands-free re-entry capability, something that has not been possible on spacecraft before,” Virgin said of the system on its website.

The test, which started at about 8 a.m. Mojave time, saw the WhiteKnightTwo carrier aircraft take off from the Mojave Air and Space Port carrying SpaceShipTwo underneath. At 46,000 feet, pilots Mark Stucky and Clint Nichols released their spacecraft from the carrier and turned on the rocket motor for a 20-second burn. They climbed as high as 69,000 feet at a maximum speed of Mach 1.43, or 1.43 times the speed of sound.
“The main progress with this test is that we deployed the full expansion (up and down) of the feather mechanism at a high altitude, alongside testing the rocket motor performance,” wrote Virgin founder Richard Branson on his blog. “This feather mechanism was the key innovation that enabled us to get into the space program in the first place. It acts like a giant shuttlecock and slows the spaceship up as it comes back into the earth’s atmosphere.”
Branson also described Thursday’s test — the second powered flight for SpaceShipTwo, which did its first in April — as “the highest commercial winged vehicle [flight] in history.”
I love science fiction films and I especially love it when the “science” part leans closer to fact than fiction. (Yes, I’m looking at you, Europa Report.) Now I’ve never seen an actual catastrophe in orbit (and I hope I never do) but I have to assume it’d look a whole lot like what’s happening in the upcoming film “Gravity,” opening in U.S. theaters on October 4. This full official trailer was released today.
A disaster film sure becomes a whole lot more interesting when everything is moving 18,000 miles an hour and there’s no up or down. And, of course, space. (!!!)

WALLOPS ISLAND, VA – An unprecedented spectacle is set to light up the skies this Friday night, Sept. 6, courtesy of NASA when America returns to the Moon with the history making nighttime launch of the LADEE lunar orbiter atop a retired and specially converted intercontinental ballistic missile (ICBM) from NASA’s Wallops Island facility on the Virginia shoreline.
Blastoff of NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory atop the maiden flight of the powerful new Minotaur V rocket is slated for 11:27 p.m. EDT Sept. 6 from Launch Pad 0B along the Eastern Shore of Virginia at NASA Wallops.
Because it’s at night and lifting off from the most densely populated region of the United States, the flames spewing from the tail of Minotaur could be visible to tens of millions of distant spectators – weather permitting – who have never before witnessed such a rocket launch.
So you don’t have to be watching locally to join in the fun and excitement. And you can always watch the NASA TV webcast online on a smartphone or laptop.

The LADEE (pronounced ‘laddie’ not ‘lady’) launch is historic in many ways.
So although the very best views are available from local areas in Virginia, Maryland and Delaware just tens of miles away from the Wallops Island launch pad, magnificent viewing opportunities are available from a broad region up and down the East Coast and into the interior.
Let’s look at some viewing maps courtesy of Orbital Sciences, the company responsible for assembling the Minotaur V and integrating it with the LADEE spacecraft – built by NASA’s Ames Research Center.
First up is the Maximum elevation map showing how high the rocket will be visible in degrees from the heavily populated US East Coast stretching from Maine to both Carolinas and into the industrial Midwest.

Herein are a series of graphics showing the Minotaur V trajectory and what you should see – during firings of the first three stages – from the perspective of standing on the ground or skyscrapers at a variety of popular destinations including the US Capitol, Lincoln Memorial, Kitty Hawk, NC, Atlantic City, NJ, New York City, Cape Cod and more.

The five stage Minotaur V rocket stands 80.6 feet (24.6 meters) tall, is 7.6 feet (2.3 m) in diameter and weighs 197,034 pounds (89,373 kilograms.
The first three stages of the Minotaur V are based on the nuclear armed Peacekeeper ICBM intercontinental ballistic missile built during the Cold War – now retired and refurbished by Orbital for peaceful uses. It’s literally beating swords into plowshares.
The 5th stage is a new addition and what makes this Minotaur a new rocket class. The added thrust is precisely what enables shooting for the Moon.

For anyone coming to the Wallops area for an eyewitness view of the launch, NASA worked with local officials to establish several viewing locations just 10 miles or so from the launch pad at the Mid-Atlantic Regional Spaceport, at NASA’s Wallops Flight Facility, Wallops Island, Va.
Visitors to the area may view the launch from Robert Reed Park on Chincoteague or Beach Road spanning the area between Chincoteague and Assateague Islands.
Both sites will feature a live countdown and broadcast and NASA personnel will be on hand to discuss the LADEE launch and goals of the mission.
A big-screen projector will broadcast live in Robert Reed Park beginning at 9:30 p.m.
“We’re excited about this partnership with the community in providing an enhanced launch experience to members of the public,” said Jeremy Eggers, public information officer for NASA Wallops in a statement. “The live countdown and launch broadcast will place people in mission control on launch night for what is already a historic mission for Wallops and the Eastern Shore.”
NASA TV starts a live broadcast of the launch at 9:30 p.m. on Sept 6 – available here: http://www.nasa.gov/ntv

The couch sized 844 pound (383 kg) robotic explorer is equipped with 3 science instruments and a laser technology demonstrator.
These include an ultraviolet and visible light spectrometer that will gather detailed information about the composition of the tenuous lunar atmosphere; a neutral mass spectrometer to measure variations in the lunar atmosphere over time; a laser dust experiment that will collect and analyze dust particle samples; and a laser communications experiment that will test the use of lasers in place of radio waves for high speed data communications with Earth.

In an exclusive new interview with Universe Today, NASA’s Ames Research Center Director Pete Worden was “very excited” to discuss the historic Moon Shot set to launch NASA’s LADEE lunar orbiter from the Virginia coast and the NASA Wallops Island facility on Friday night, Sept. 6, that boasts “a new modular design” that can revolutionize how we explore our solar system “with robotic orbiters, landers and rovers” – and is aimed at “answering fundamental science questions.”
“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Worden told Universe Today. NASA Ames leads the LADEE mission. “It will study the pristine moon to study significant questions.”
“And it will demonstrate a new modular approach that will give us science at a lower cost. We are very excited.”
“It will tell us a lot about the moon,” Worden told me.
When America returns to the Moon with the LADEE spacecraft blasting off shortly before midnight Sept. 6, it could potentially be watched by many tens of millions of spectators – weather permitting – along the US East Coast stretching from Maine to the Carolina’s and into parts of the Midwest. See launch visibility map below.

And the science timing for LADEE’s lunar mission is just perfect as well since several countries and corporations are gearing up to dispatch a batch of new orbiters and landers to Earth’s nearest neighbor that could change its character forever.
“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”
The purpose of LADEE’s trio of science instruments is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface.

The couch sized probe is built on a ‘modular common spacecraft bus’, or body, that could be implemented on space probes to explore a wide variety of targets in the solar system.
“We think the modular bus is a winner,” Worden explained to Universe Today.
“LADEE could lead to other low cost missions to orbit and even land on the Moon, near Earth asteroids, Mercury and also the moons of Mars.”
“The LADEE bus is a strong contender for future NASA planetary missions, especially landers on bodies with a tenuous atmosphere. And small micro-rovers are possible too. We are really proud of it!”

LADEE is NASA’s first ever planetary mission to launch from the Eastern Shore of Virginia at NASA’s Wallops Flight Facility on Wallops Island. The blastoff is expected to draw large crowds. Some local hotels are already sold out.
The Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory is NASA’s next mission to the Moon.
It thunder’s to space at 11:27 p.m. Friday, Sept. 6, from launch complex 0B at NASA’s Wallops Island facility and the Mid-Atlantic Regional Spaceport (MARS) atop the maiden flight of the new, solid fueled Minotaur V rocket developed by Orbital Sciences Corp.

The goal of the $280 Million mission is to gain a thorough understanding of long-standing unknowns about the tenuous atmosphere, dust and surface interactions that will help scientists understand other planetary bodies as well.
“After Apollo, the amazing thing is that we opened as many questions as we answered,” said Worden. “One of the key issues is – What is the environment on the Moon’s surface from the lunar day to the lunar night?”
“And what are the limitations that would place on our activities there?”
“Although the moon has a tenuous atmosphere it’s actually very active and interacts very strongly with the solar wind. It may produce something that on Earth we would call a ‘dust storm’.”
“We also wish to have the ‘ground truth’ [measurements] of the Moon’s environment before humans change things.”
And change is inexorably coming to the Moon rather soon.
“The Chinese plan to land on the Moon by year’s end,” Worden elaborated.
“What we found during Apollo is that an artificial disturbance very considerably changes the Moon’s atmosphere – or exosphere.”
“So we really want to known the pristine state of the lunar exosphere before its changed by human activity.”
“The data we have from Apollo surface measurements shows that it took many months for the lunar exosphere to go back to its pristine state.”
“Now there are probably a half dozen to a dozen programs planning to land on the Moon in the next decade. So we may never see the Moon’s pristine state again!”
“So these are pretty significant questions that we will have an opportunity to answer with LADEE.”
LADEE Science Instrument locations
LADEE is the first spacecraft of any kind that’s been designed, developed, built, integrated and tested at NASA’s Ames Research Center in Moffett Field, Calif.
“This is our first complete mission built out at Ames,” Worden explained.
“It’s also the first of a new paradigm where we are trying to develop a low cost modular bus design.
The approach on LADEE was to make it a mix and match modular bus – rather than a singular modular bus.
“So we have modular slices that use a propulsion stage, lander stage, communications stage, science payload stage, bus housekeeping stage and more,” Worden told me.
“In the past many others tried to build a ‘one size fits all’ modular bus. But it turns out that one size does NOT fit all needs.”
“So we took a page from how you build desktop computers.”
“We put in different modules that you can expand or subtract much more easily without changing the whole fundamental architecture or design.”
“So assuming this works well, I think you will see a lot more missions. And that makes it really exciting as our first mission.”
And the Ames modular bus has definitely sparked entrepreneurial interest.
“The bus is already an approach being used by at least one of the Google Lunar X-Prize competitors! The Moon Express team has looked at it a lot to transition that capability to them,” Worden explained.
How about future NASA missions?
“The LADEE bus is also a key part of several of our Ames proposals for future planetary missions,” Worden replied.
“The original design concept about seven years ago was for a small lunar lander. The lander propulsion would likely be a solid fueled stage.”
“Ultimately, NASA decided to go with the orbiter instead. And that showed the strength of the modular bus design – that it was very easy to change it from a lunar lander to the LADEE mission orbiter studying the lunar exosphere.”
I asked if it could deploy a small rover too?
“Yes- a small, micro rover is possible, perhaps 10 to 20 inches in size. And you could pack a lot of science on the small rover using today’s technology!

Thus there are numerous exploration possibilities – all dependent on the Federal budget for NASA in this extremely difficult fiscal environment.
NASA Ames had “built parts and spacecraft components and science instruments before, but not a spacecraft in the entirety and in house,” Worden told Universe Today.
For example, a few years back Ames built the LCROSS lunar impacting spacecraft that smashed into the Moon’s south pole and discovered a treasure trove of water ice.
LCROSS piggybacked as a secondary science mission payload onto NASA’ s Lunar Reconnaisannce Orbiter (LRO) when the duo launched from Cape Canaveral, Florida atop an Atlas V rocket.
NASA Ames has now taken the next step – having designed and built the whole LADEE spacecraft from beginning to end.
“This is our first real baby. It’s very exciting,” beamed Worden.
“LADEE is a pretty phenomenal mission.”
They say “Virginia is for Lovers’
Well coming this Friday, “Virginia is for Space Lovers too!”

It’s easy to take the International Space Station for granted. It’s been planned, under construction and/or operated for decades. Humans have occupied it continuously for 4,684 days (close to 13 years) as of today. According to two space policy experts, however, NASA should already be thinking of what it’s going to do next after the station’s current agreement expires in 2020.
Ignoring the deadline, they said, could lead to consequences such as (in one scenario) the end of U.S. government spaceflight altogether.
Below are edited excerpts from two officials from George Washington University’s Elliott School of International Affairs. Scott Pace is its director, and John M. Logsdon is a professor emeritus. They spoke with reporters Thursday (Aug. 29) about the coming NASA budget decision and their views on the agency’s future.
We’d also like to get your feedback on their ideas, so please leave your thoughts in the comments.
Pace: In my view, the House numbers are complying with the Budget Control Act in terms of sequestration numbers. In the Senate, the numbers were not in line with the Budget Control Act, but reflected what the priorities of the authorization committee were … I would argue, and we’ll see if others agree, that the Senate has marginalized themselves in this discussion. The appropriations staff will have the larger say in that, but on the House side, the authorizors and the appropriators will be together because they have discussed what their priorities were.”
Where NASA’s direction comes from:
Logsdon: It’s a residual of 40 years of failure to reach consensus of what the U.S. should be doing in space and particularly, human spaceflight. In the first year and a half of the Nixon administration, he was faced with what to do after Apollo and basically punted. He said, “Let’s develop means, rather than set goals.” The means was the shuttle … The lack of leadership of this administration, which is not much different than most presidents since Nixon and including Nixon, have put us in a situation that is unfortunate, and, as Scott [Pace] says, leads to a lot of drift and lack of sense of purpose.
Pace: [One goal for NASA often is to implement] priorities of decadal surveys from the National Academy of Sciences. Things like the asteroid redirect mission, which will burden portions of the human and science programs, have no decadal survey mention or no larger contribution to the science. It’s another capability-driven-evolution sort of project, with some very basic flaws to it in terms of not providing that long-term sense of strategic purpose.

Logsdon: There’s not enough money to have a robust space exploration program and to use the space station at a $3 billion a year level in 2028. None of the current partners — with a possible exception of Canada — but certainly, Europe and Japan are not enthusiastic about spending money on space station post-2020. They really had to be dragged, their governments had to be dragged, to commit the funds for the extension to 2020. It’s not clear, if there is a decision to go beyond, whether the United States will have its early partners [committed.]
Pace: What happens with other major scientific facilities that NASA has, like the Hubble Space Telescope, is you have a senior review. After you’ve met the initial requirements [of the mission], you ask what is the facility costing me, what am I getting out of it, and make a decision whether to continue. You will see, in anticipation of 2020, you will see the beginnings of a senior review to see what will be in the NASA 2020 budget. It is dependent upon data being created now — the scientific and technical benefits — and where will the benefits flow for plans beyond space station. If there are no plans for human flight beyond space station … the default option is to do the station as long as it is technically capable, but eventually it will be deorbited. And there will be an end to U.S. government spaceflight.

If government-funded human spaceflight could end in the United States:
Pace: I can imagine a President presiding over the end of human spaceflight, not as a conscious decision but as an unfortunate accident. Drift is the most dangerous thing for NASA.
Logsdon: Would any President be willing to be that person to end the government-sponsored spaceflight program? I’m not sure the answer is no. It could be that a future President could say we’ve done it and there’s no future reasoning to continue at fairly high expense to continue to do it. But I would speculate the more likely answer, given the industrial and regional interests, is some sort of limping through human spaceflight. It’s more similar than different for the past four decades.
What NASA needs right now:
Logsdon: I’m taking less about the NASA leadership than I am the White House and Congressional leadership. What’s missing is a sense of strategic purpose of the organization, what should it be doing, and that is the job of a national leader. It is enunciating for NASA, as well as other government agencies, for what its long-term and even midterm strategic purpose is in terms of the natinoal interest ought to be.
Pace: [The United States must determine] what is the role of international leadership in space for the United States and to what extent are we willing to make plans for beyond the station. 2020 is not that far away. The focus on NASA right now, with ISS, is utilization. The station has been a great diplomatic success, great technical success, but it’s not clear if it will be a great scientific success.
Are Earthlings really Martians ? Did life arise on Mars first and then journey on meteors to our planet and populate Earth billions of years ago? Earth and Mars are compared in size as they look today.

Did life arise on Mars first and then journey on rocks to our planet and populate Earth billions of years ago? Earth and Mars are compared in size as they look today. NASA’s upcoming MAVEN Mars orbiter is aimed at answering key questions related to the habitability of Mars, its ancient atmosphere and where did all the water go. Story updated[/caption]
That’s the controversial theory proposed today (Aug. 29) by respected American chemist Professor Steven Benner during a presentation at the annual Goldschmidt Conference of geochemists being held in Florence, Italy. It’s based on new evidence uncovered by his research team and is sure to spark heated debate on the origin of life question.
Benner said the new scientific evidence “supports the long-debated theory that life on Earth may have started on Mars,” in a statement. Universe Today contacted Benner for further details and enlightenment.
“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner told Universe Today. “AND IF you think that life began with RNA, THEN you place life’s origins on Mars.” Benner said he has experimental data as well.
First- How did ancient Mars life, if it ever even existed, reach Earth?
On rocks violently flung up from the Red Planet’s surface during mammoth collisions with asteroids or comets that then traveled millions of miles (kilometers) across interplanetary space to Earth – melting, heating and exploding violently before the remnants crashed into the solid or liquid surface.
An asteroid impacts ancient Mars and send rocks hurtling to space – some reach Earth. Did they transport Mars life to Earth? Or minerals that could catalyze the origin of life on Earth?
“The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,” says Benner, of The Westheimer Institute of Science and Technology in Florida. That theory is generally known as panspermia.
To date, about 120 Martian meteorites have been discovered on Earth.
And Benner explained that one needs to distinguish between habitability and the origin of life.
“The distinction is being made between habitability (where can life live) and origins (where might life have originated).”
NASA’s new Curiosity Mars rover was expressly dispatched to search for environmental conditions favorable to life and has already discovered a habitable zone on the Red Planet’s surface rocks barely half a year after touchdown inside Gale Crater.
Furthermore, NASA’s next Mars orbiter- named MAVEN – launches later this year and seeks to determine when Mars lost its atmosphere and water- key questions in the Origin of Life debate.

Of course the proposed chemistry leading to life is exceedingly complex and life has never been created from non-life in the lab.
The key new points here are that Benner believes the origin of life involves “deserts” and oxidized forms of the elements Boron (B) and Molybdenum (Mo), namely “borate and molybdate,” Benner told me.
“Life originated some 4 billion years ago ± 0.5 billon,” Benner stated.
He says that there are two paradoxes which make it difficult for scientists to understand how life could have started on Earth – involving organic tars and water.
Life as we know it is based on organic molecules, the chemistry of carbon and its compounds.
But just discovering the presence of organic compounds is not the equivalent of finding life. Nor is it sufficient for the creation of life.
And simply mixing organic compounds aimlessly in the lab and heating them leads to globs of useless tars, as every organic chemist and lab student knows.
Benner dubs that the ‘tar paradox’.
Although Curiosity has not yet discovered organic molecules on Mars, she is now speeding towards a towering 3 mile (5 km) high Martian mountain known as Mount Sharp.
Curiosity Spies Mount Sharp – her primary destination
Curiosity will ascend mysterious Mount Sharp and investigate the sedimentary layers searching for clues to the history and habitability of the Red Planet over billions of years. This mosaic was assembled from over 3 dozen Mastcam camera images taken on Sol 352 (Aug 2, 2013. Credit: NASA/JPL-Caltech/MSSS/ Marco Di Lorenzo/Ken Kremer-kenkremer.com
Upon arrival sometime next spring or summer, scientists will target the state of the art robot to investigate the lower sedimentary layers of Mount Sharp in search of clues to habitability and preserved organics that could shed light on the origin of life question and the presence of borates and molybdates.
It’s clear that many different catalysts were required for the origin of life. How much and their identity is a big part of Benner’s research focus.
“Certain elements seem able to control the propensity of organic materials to turn into tar, particularly boron and molybdenum, so we believe that minerals containing both were fundamental to life first starting,” says Benner in a statement. “Analysis of a Martian meteorite recently showed that there was boron on Mars; we now believe that the oxidized form of molybdenum was there too.”
The second paradox relates to water. He says that there was too much water covering the early Earth’s surface, thereby causing a struggle for life to survive. Not exactly the conventional wisdom.
“Not only would this have prevented sufficient concentrations of boron forming – it’s currently only found in very dry places like Death Valley – but water is corrosive to RNA, which scientists believe was the first genetic molecule to appear. Although there was water on Mars, it covered much smaller areas than on early Earth.”
Parts of ancient Mars were covered by oceans, lakes and streams of liquid water in this artists concept, unlike the arid and bone dry Martian surface of today. Subsurface water ice is what remains of Martian water.
I asked Benner to add some context on the beneficial effects of deserts and oxidized boron and molybdenum.
“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner explained to Universe Today.
“We require mineral species like borate (to capture organic species before they devolve to tar), molybdate (to arrange that material to give ribose), and deserts (to dry things out, to avoid the water problem).”
“Various geologists will not let us have these [borates and molybdates] on early Earth, but they will let us have them on Mars.”
“So IF you believe what the geologists are telling you about the structure of early Earth, AND you think that you need our chemistry to get RNA, AND IF you think that life began with RNA, THEN you place life’s origins on Mars,” Benner elaborated.
“The assembly of RNA building blocks is thermodynamically disfavored in water. We want a desert to get rid of the water intermittently.”
I asked Benner whether his lab has run experiments in support of his hypothesis and how much borate and molybdate are required.
“Yes, we have run many lab experiments. The borate is stoichiometric [meaning roughly equivalent to organics on a molar basis]; The molybdate is catalytic,” Benner responded.
“And borate has now been found in meteorites from Mars, that was reported about three months ago.
At his talk, Benner outlined some of the chemical reactions involved.
Although some scientists have invoked water, minerals and organics brought to ancient Earth by comets as a potential pathway to the origin of life, Benner thinks differently about the role of comets.
“Not comets, because comets do not have deserts, borate and molybdate,” Benner told Universe Today.

Benner has developed a logic tree outlining his proposal that life on Earth may have started on Mars.
“It explains how you get to the conclusion that life originated on Mars. As you can see from the tree, you can escape that conclusion by diverging from the logic path.”
Finally, Benner is not one who blindly accepts controversial proposals himself.
He was an early skeptic of the claims concerning arsenic based life announced a few years back at a NASA sponsored press conference, and also of the claims of Mars life discovered in the famous Mars meteorite known as ALH 84001.
“I am afraid that what we thought were fossils in ALH 84001 are not.”
The debate on whether Earthlings are really Martians will continue as science research progresses and until definitive proof is discovered and accepted by a consensus of the science community of Earthlings – whatever our origin.
On Nov. 18, NASA will launch its next mission to Mars – the MAVEN orbiter. Its aimed at studying the upper Martian atmosphere for the first time.
“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water go and how and when was it lost,” said Bruce Jakosky to Universe Today at a MAVEN conference at the University of Colorado- Boulder. Jakosky, of CU-Boulder, is the MAVEN Principal Investigator.
MAVEN will shed light on the habitability of Mars billions of years ago and provide insight on the origin of life questions and chemistry raised by Benner and others.

An graphic released of an Iranian space capsule capable of carrying humans to space. Via ISNA.
After Iran launched a monkey in a suborbital rocket earlier this year, they are now setting their sights on sending humans to orbit, according to the Iranian news agency ISNA. The news release says researchers at the University of Haj Nasir “have designed and built a manned spacecraft,” but only images of basic designs were released.
The spacecraft appears to be a classic capsule design, and is capable of carrying “one to three people to lower orbits for several hours. This type of aircraft is made up of several modules.”
The researchers, Leila Khalajzadeh and Mehran Shams, were reported as saying in their presentation that the capsule design is the most economical type of spacecraft.
The Israeli news site Hayadan reports that Tal Inbar, head of the Space and UAV Research Center at Fisher Institute for Air and Space Strategic Studies in Israel, says that no technical data was released from Iran on the new spacecraft designs, nor have they provided information about the launch vehicle required to send the capsule to space.
According to details released earlier by the Iranian space agency, they want to launch the first sub-orbital spaceflight with an Iranian on board by 2016 at an altitude below 200 kilometers as preparation for the eventual orbital spaceflight.
Iranian participation in the future Chinese space station program has also been discussed.
Reportedly, much of Iran’s technological equipment derives from modified Chinese and North Korean technology. In 2008, Iran successfully launched a two-stage all solid-fuel sub-orbital sounding rocket called the Kavoshgar-1 (Explorer-1), for the first sub-orbital test flight from the Shahroud space launch complex. Later, in 2010-2013, at least three animal flight tests were sent on suborbital launches, some flights with outright failures, others with varying degrees of success.

A spectacular nighttime blastoff blazing a historic trail to the Moon is set to soar in two weeks time when NASA’s LADEE spacecraft lifts off from the Eastern Shore of Virginia at NASA’sWallops Flight Facility on Wallops Island – from America’s newest spaceport.
NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory will thunder to space at 11:27 p.m. Friday, Sept. 6, from the commercial Mid-Atlantic Regional Spaceport (MARS) launch complex 0B at NASA’s Wallops Island facility atop the maiden flight of the new, solid fueled Minotaur V rocket developed by Orbital Sciences Corp.
LADEE’s late night launch will be absolutely spectacular and visible to tens of millions of spectators up and down the US East coast and interior areas stretching into the Midwest- weather permitting.
“I love this mission,” said John Grunsfeld, NASA Associate Administrator for Science at NASA Headquarters, at a media briefing today, Aug. 22.
LADEE’s Ticket to the Moon – 5th Stage of new Minotaur V rocket

“With NASA’s prior LRO and GRAIL spacecraft we studied the Moon’s surface and interior. Now with LADEE we study the atmosphere and dust,” said John Grunsfeld.
The purpose of LADEE is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface. In turn this will lead to a better understanding of other planetary bodies in our solar system and beyond.
The small car sized LADEE lunar orbiter mission will be historic in many ways. It’s the first probe of any kind ever launched to beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission from Wallops.
It also marks the first launch of a five stage rocket and the first launch of a decommissioned Peacekeeper missile from Wallops.
The first three stages of the Minotaur V are based on the nuclear armed Peacekeeper ICBM intercontinental ballistic missile built during the Cold War – now retired and refurbished by Orbital for peaceful uses. Its literally beating sword into ploughshares.
The 5th stage is a new addition and what makes this Minotaur a new rocket class. The added thrust is precisely what enables shooting for the Moon.
Recently, I had an exclusive tour and photoshoot up close and personal with the upper stages of LADEE’s Minotaur V rocket at Wallops prior to integration at the commercial launch pad – 0B – and will be reporting on that here and in upcoming stories.

“LADEE is equipped with three science instruments to study the atmosphere and dust and a lunar laser technology demonstration,” said Joan Salute, LADEE program executive, NASA Headquarters.
These include an ultraviolet and visible light spectrometer that will gather detailed information about the composition of the tenuous lunar atmosphere; a neutral mass spectrometer to measure variations in the lunar atmosphere over time; a laser dust experiment that will collect and analyze dust particle samples; and a laser communications experiment that will test the use of lasers in place of radio waves for high speed dad communications with Earth.
“The lunar atmosphere is so thin that the molecules never collide,’ said Sarah Noble, LADEE program scientist, NASA Headquarters.
“It’s a ‘Surface Boundary Exosphere’ which is actually the most common type of atmosphere in our Solar System.”
Scientists also hope to solve a mystery dating back nearly five decades to the Apollo moon landing era, by determining if electrically charged lunar dust is responsible for the pre-sunrise horizon glow seen by the Apollo astronauts and also by the unmanned Surveyor 7 lander, according to Noble.
“This is the first NASA mission with a dedicated laser communications experiment,” said Don Cornwell, mission manager for the Lunar Laser Communications Demonstration, NASA’s Goddard Space Flight Center, Greenbelt, Md.
I asked when we could see laser communications implemented on future NASA spacecraft?
“A new laser communications system could possibly be used on the 2020 Mars rover from the surface of Mars,” Grunsfeld told Universe Today.
The couch sized 844 pound (383 kg) robotic explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.
The spacecraft is a first of its kind vehicle built from a NASA Ames-developed Modular Common Spacecraft Bus architecture that can be applied to other missions. The mission cost is approximately $280 million.
The Minotaur V will boost LADEE into a highly elliptical orbit. Then over the next 23 days, as LADEE orbits Earth 3.5 times, the Moon’s gravitational field will increase the perigee of its orbit. The spacecraft will fire its on-board braking thrusters to achieve lunar orbit.

The mission will fly in a very low science orbit of about 50 kilometers altitude above the moon. The science mission duration is approximately 100 days.
“It’s limited by the amount of onboard fuel required to maintain orbit,” Doug Voss, launch manager, Wallops, told Universe Today.
“I’m excited about the night launch because people up and down the Atlantic seacoast will be able to see it,” Jim Green, Planetary Science Division Director at NASA HQ, told me.
And don’t forget that NASA has a 2nd really big launch from Wallops slated for Sep. 17 – with blastoff of the Orbital Sciences Antares rocket and Cygnus cargo carrier on their historic 1st mission to the International Space Station (ISS).
I’ll be on site at Wallops for both historic launches on Sep. 6 and 17 – reporting for Universe Today.

It’s never a dull moment for NASA’s Curiosity rover at T Plus 1 Year since touchdown on the Red Planet and T Minus 1 year to arriving at her primary target, the huge mountain overwhelming the center of the landing site inside Gale Crater.
Curiosity is literally and figuratively zooming in on stunningly beautiful and mysterious Mount Sharp (see our new mosaics above/below), her ultimate destination, while conducting ‘Science on the Go’ with her duo of chemistry labs – SAM and CheMin – and 8 other science instruments as she passes the 2 kilometer driving milestone today; Aug 20 !
“We are holding samples for drops to ChemMin and SAM when the science team is ready for it,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview.
“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.
So, those samples were altered by liquid Martian water – a prerequisite for life.

In fact the car sized rover has saved samples from both the ‘John Klein’ and ‘Cumberland’ drill sites collected previously in the ‘Yellowknife Bay’ area for analysis by the miniaturized labs in the rovers belly -when the time is right.
“Curiosity has stored a Cumberland sample and still has a John Klein sample on board for future use,” Erickson explained.
And that time has now arrived!
“We have put a sample from the Cumberland drill hole into SAM for more isotopic measurements,” reported science team member John Bridges in a blog update on Sol 363, Aug. 14, 2013.
“The sample had been cached within the robotic arm’s turret.”
Curiosity is multitasking – conducting increasingly frequent traverses across the relatively smooth floor of Gale Crater while running research experiments for her science handlers back here on Earth.

She’s captured stunning new views of Mount Sharp – rising 5 km (3 miles) high into the sky – and movies of Mars tiny pair of transiting moons while ingesting new portions of the drilled rock samples acquired earlier this year.

The sample analysis is still in progress.
“The SAM data have not all been received yet,” wrote science team member Ken Herkenhoff in a blog update.
Earlier analysis of sample portions from both ‘John Klein’ and ‘Cumberland’ revealed that the Yellowknife Bay area on Mars possesses the key mineral ingredients proving that Red Planet was once habitable and could have sustained simple microbial life forms.
The scientists are seeking further evidence and have yet to detect organic molecules – which are the building blocks of life as we know it.

Yellowknife Bay resembles a dried out river bed where liquid water once flowed eons ago when the Red Planet was far warmer and wetter than today.
As the 1 ton robot ascends Mount Sharp, she will examine sedimentary layers layed down on ancient Mars over hundreds of millions and perhaps billions of years of past history and habitability.
And just as the rover was celebrating 1 year on Mars on Aug 5/6, she found an intriguing sand dune on Sol 354. See our mosaic
“The rover paused to take images of its tracks after crossing a windblown ripple,” Herkenhoff reported.
As the six wheeled rover approaches Mount Sharp over the next year, she will eventually encounter increasing treacherous dunes that she must cross before beginning her mountain climbing foray.
As of today, Sol 369 (Aug. 20) Curiosity has broken through the 2 kilometer driving mark with a new 70 meter drive, snapped over 75,000 images and fired over 75,000 laser shots.
Mount Sharp is about 8 kilometers (5 miles) distant as the Martian crow flies.
How long will the journey to Mount Sharp require?
“Perhaps about a year,” Erickson told me. “We are trying to make that significantly faster by bringing autonav [autonomous navigation software] online.”
“That will help. But how much it helps really depends on the terrain.”
So far so good.
Meanwhile NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), recently arrived at the Kennedy Space Center after a cross country flight.
Kennedy technicians are completing assembly and check out preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from Florida atop an Atlas V rocket similar to the one that launched Curiosity nearly 2 years ago.
And I’ll be at Kennedy to report up close on MAVEN’s launch.

If you’ve got a new use for the mobile launcher platforms NASA used for the shuttle program, the agency is all ears.
NASA invited government and commercial entities to submit their ideas for the platforms, which used to ferry the space shuttles and the Apollo rockets from the Vehicle Assembly Building to their launch pads.

The ideal for NASA is to make them available for commercial launch activity. “Interested parties are requested to provide the following … estimated annual launch manifest, plans for retrofitting, storing, transporting, estimated schedule for acquiring use of the MLP(s), and the length of time the MLP(s) would be required for a particular activity,” the agency stated in a request for information.
Other options for the platforms could include modifying them for use in oil rigs, artificial reefs or even museum exhibits. Deconstruction is also being considered.
Each of the three platforms is two storeys tall, weigh 8.2 million pounds, with a platform of about 160 feet by 135 feet.
