This past weekend technicians completed assembly of NASA’s first Orion crew module at the agency’s Neil Armstrong Operations and Checkout (O & C) Facility at the Kennedy Space Center (KSC) in Florida, signifying a major milestone in the vehicles transition from fabrication to full scale launch operations.

Orion is NASA’s next generation human rated vehicle and is scheduled to launch on its maiden uncrewed mission dubbed Exploration Flight Test-1 (EFT-1) in December 2014. It replaces the now retired space shuttle orbiters.

The black Orion crew module (CM) sits stacked atop the white service module (SM) in the O & C high bay photos, shown above and below.

The black area is comprised of the thermal insulating back shell tiles. The back shell and heat shield protect the capsule from the scorching heat of re-entry into the Earth’s atmosphere at excruciating temperatures reaching over 4000 degrees Fahrenheit (2200 C) – detailed in my story here.

Technicians and engineers from prime contractor Lockheed Martin subsequently covered the crew module with protective foil. The CM/SM stack was then lifted and moved for the installation of the Orion-to-stage adapter ring that will mate them to the booster rocket.

At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and hits 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 next step in Orion’s multi stage journey to the launch pad follows later this week with transport of the CM/SM stack to another KSC facility named the Payload Hazardous Servicing Facility (PHFS) for fueling, before moving again for the installation of the launch abort system (LAS) in yet another KSC facility.

The Orion EFT-1 test flight is slated to soar to space atop the mammoth, triple barreled United Launch Alliance (ULA) Delta IV Heavy rocket from Cape Canaveral, Florida, on Dec. 4, 2014 .

The state-of-the-art Orion spacecraft will carry America’s astronauts on voyages venturing farther into deep space than ever before – past the Moon to Asteroids, Mars and Beyond!

NASA is simultaneously developing a monster heavy lift rocket known as the Space Launch System or SLS, that will eventually launch Orion on its deep space missions.

The maiden SLS/Orion launch on the Exploration Mission-1 (EM-1) unmanned test flight is now scheduled for no later than November 2018 – read my story here.

SLS will be the world’s most powerful rocket ever built.

The two-orbit, four and a half 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.

The EFT-1 mission will test the systems critical for EM-1 and future human missions to deep space that follow.

The Orion EFT-1 capsule has come a long way over the past two years of assembly.

The bare bones, welded shell structure of the Orion crew cabin arrived at KSC in Florida from NASA’s Michoud facility in New Orleans in June 2012 and was officially unveiled at a KSC welcoming ceremony on 2 July 2012, attended by this author.

“Everyone is very excited to be working on the Orion. We have a lot of work to do. It’s a marathon not a sprint to build and test the vehicle,” said Jules Schneider, Orion Project manager for Lockheed Martin at KSC, during an exclusive 2012 interview with Universe Today inside the Orion clean room at KSC.

Mars Panorama Shows Off Rocks, Mountains and Curiosity Rover

Hey, it’s Mars in your browser! Panning around this scene that the Mars Curiosity rover captured earlier this month is the next best thing to being on the Red Planet.

Close by the rover’s is the terrain that proved far more challenging for mission planners than anticipated, and further in the distance you can see mountains — including the ultimate destination for this mission, Mount Sharp (Aeolis Mons).

The panorama, done by Andrew Bodrov, is based on pictures that Curiosity took during Sol 739 of its mission on Mars, which began in August 2012.

The Curiosity mission recently drew the concern of a NASA Senior Review panel, which said that the mission may be moving too fast to Mount Sharp and sacrificing looking carefully at other sites that could preserve signs of habitability.

The rover recently passed over a drilling target due to the nature of the rocks it was looking at, which were loose, unstable and at risk to the rover if they moved in an unpredictable way.

Wanna Trip To Space? To Raise Money, Mars One Is Offering A Lynx Joyride

Private trips to space are pricey, but from time to time contests come up that offer even those of modest means the chance to get there.

Take Mars One’s latest publicity campaign, which is to offer a chance for a trip upon the (so-far-unflown-in-space) Lynx spacecraft in exchange for donating to the organization, which plans to launch a one-way human trip to Mars in the next decade.

“The campaign will provide funding for a 2015 Earth mission, which is a simulation project to replicate the future Mars human settlement here on Earth, as well as the 2018 Mars mission to Mars,” Mars One stated.

The campaign, called “Ticket To Rise“, is essentially a fundraising campaign for Mars One. The group is selling memberships, selfies of photographs with Mars in the background (during a 2018 mission), T-shirts and at the high end, coins or attendance at VIP events.

The Mars One plan to bring people to the planet has generated lots of publicity among the media, amid skepticism that the funding and technology could be available to bring people to the Red Planet starting in 2024. The organization began whittling down applicants this year and as of May, said there are now 705 “potential Mars settlers” remaining.

If successful, Mars One hopes to bring settlers to the Red Planet every two years, four people at a time, and leave them there to establish a colony. The organization says there are “no new technology developments” needed to get people to Mars, and that it has gone to “major aerospace companies around the world” to figure out what needs to be done.

The XCOR Lynx spacecraft is one of a small number of vehicles competing for the chance to bring wealthy people into space. From time to time, the company has partnered with other entities (such as men’s grooming company AXE) to run contests to drum up interest in their product, which so far is unflown in space.

Rosetta’s Cloudy Comet Shroud Spotted From The Ground, While Spacecraft Picks Up Dust Grains

This picture shows it is possible to look at Rosetta’s comet from Earth, but what a lot of work it requires! The picture you see above is a composite of 40 separate images taken by the Very Large Telescope (removing the background stars).

Despite the fact that Rosetta is right next to Comet 67P/Churyumov–Gerasimenko, ground-based observatories are still useful because they provide the “big picture” on what the comet looks like and how it is behaving. It’s an observational challenge, however, as the comet is still more than 500 million kilometers (310 million miles) from the Sun and hard to see.

On top of that, the European Space Agency says the comet is sitting in a spot in the sky where it is difficult to see it generally, as the Milky Way’s prominent starry band is just behind. But what can be seen is spectacular.

“Although faint, the comet is clearly active, revealing a dusty coma extending at least 19 000 km [11,800 miles] from the nucleus,” ESA stated. “The comet’s dusty veil is not symmetrical as the dust is swept away from the Sun – located beyond the lower-right corner of the image – to begin forming a tail.”

And that dust is beginning to show up in Rosetta’s grain collector, as you can see below!

Rosetta’s Cometary Secondary Ion Mass Analyser (COSIMA) picked up several dust grains in August, which you can see in the image, and are now looking at the target plate more closely to figure out more about the dust grains.

“Some will be selected for further analysis: the target plate will be moved to place each chosen grain under an ion gun which will then ablate the grain layer by layer. The material is then analyzed in a secondary ion mass spectrometer to determine its composition,” ESA stated.

All of these results were presented today (Sept. 8) at the European Planetary Science Congress 2014.

Sweet Success for SpaceX with Second Successful AsiaSat Launch This Summer

Shortly after midnight this morning, Sunday, Sept. 7, SpaceX scored a major success with the spectacular night time launch of the commercial AsiaSat 6 satellite from Cape Canaveral, Florida, that briefly turned night into day along the Florida Space Coast.

A SpaceX Falcon 9 rocket carrying the AsiaSat 6 communications satellite blasted off at 1 a.m. EDT today from Space Launch Complex 40 on Cape Canaveral Air Force Station at the opening of the launch window.

The two stage, 224 foot-tall (68.4 meter-tall) Falcon 9 rocket performed flawlessly, soaring to space and placing the five ton AsiaSat 6 into a geosynchronous transfer orbit.

SpaceX confirmed a successful spacecraft separation about 32 minutes after liftoff and contact with the satellite following deployment at about 1:30 a.m. EDT.

The Falcon 9 delivered AsiaSat 6 satellite into a 185 x 35,786 km geosynchronous transfer orbit at 25.3 degrees.

Sunday’s liftoff marked a sweet success for SpaceX since it was the second successive launch of an AsiaSat communications satellite in about a month’s time. AsiaSat is a telecommunications operator based in Hong Kong.

The first launch of the two satellite series with AsiaSat 8 took place from Cape Canaveral on Aug. 5.

The launch was webcast live by SpaceX on the firm’s website.

The private satellites will serve markets in Southeast Asia and China.

Thailand’s leading satellite operator, Thaicom, is a partner of AsiaSat on AsiaSat 6 and will be using half of the satellite’s capacity to provide services under the name of THAICOM 7, according to the press kit.

The AsiaSat 6 launch was originally scheduled for Aug. 26, just 3 weeks after AsiaSat 8, but was postponed at the last minute after the detonation of a Falcon 9R test rocket at a SpaceX test site in Texas.

SpaceX CEO Elon Musk said the team needed to recheck the rocket systems to insure a successful blastoff since both rockets use Merlin 1D engines, but are configured with different software.

The Falcon 9 first stage is loaded with liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants and powered by nine Merlin 1D engines that generate about 1.3 million pounds of liftoff thrust.

The second stage is powered by a single, Merlin 1D vacuum engine.

Today’s liftoff was critical in clearing the path for the next SpaceX launch – the CRS-4 cargo resupply mission for NASA bound for the International Space Station (ISS).

The Falcon 9 launch of the cargo Dragon on the CRS-4 mission is currently targeted for no earlier than Sept. 19. But a firm launch date has not been set.

Story updated[/caption]

NASA’s MAVEN Mars Orbiter is “ideally” instrumented to uniquely “map the composition of Comet Siding Spring” in great detail when it streaks past the Red Planet during an extremely close flyby on Oct. 19, 2014 – thereby providing a totally “unexpected science opportunity … and a before and after look at Mars atmosphere,” Prof. Bruce Jakosky, MAVEN’s Principal Investigator of CU-Boulder, CO, told Universe Today in an exclusive interview.

The probes state-of-the-art ultraviolet spectrograph will be the key instrument making the one-of-a-kind compositional observations of this Oort cloud comet making its first passage through the inner solar system on its millions year orbital journey.

“MAVEN’s Imaging Ultraviolet Spectrograph (IUVS) is the ideal way to observe the comet coma and tail,” Jakosky explained.

“The IUVS can do spectroscopy that will allow derivation of compositional information.”

“It will do imaging of the entire coma and tail, allowing mapping of composition.”

Comet: Siding Spring. The images above show -- before and after filtering -- comet C/2013 A1, also known as Siding Spring, as captured by Wide Field Camera 3 on NASA's Hubble Space Telescope.  Image Credit: NASA, ESA, and J.-Y. Li (Planetary Science Institute)

Moreover the UV spectrometer is the only one of its kind amongst NASA’s trio of Martian orbiters making its investigations completely unique.

“IUVS is the only ultraviolet spectrometer that will be observing the comet close up, and that gives the detailed compositional information,” Jakosky elaborated

And MAVEN, or the Mars Atmosphere and Volatile Evolution, is arriving just in the nick of time to fortuitously capture this fantastically rich data set of a pristine remnant from the solar system’s formation.

The spacecraft reaches Mars in less than 15 days. It will rendezvous with the Red Planet on Sept. 21 after a 10 month interplanetary journey from Earth.

Furthermore, since MAVEN’s purpose is the first ever detailed study of Mars upper atmosphere, it will get a before and after look at atmospheric changes.

“We’ll take advantage of this unexpected science opportunity to make observations both of the comet and of the Mars upper atmosphere before and after the comet passage – to look for any changes,” Jakosky stated.

How do MAVEN’s observations compare to NASA’s other orbiters Mars Odyssey (MO) and Mars Reconnaissance Orbiter (MRO), I asked?

“The data from the other orbiters will be complementary to the data from IUVS.”

“Visible light imaging from the other orbiters provides data on the structure of dust in the coma and tail. And infrared imaging provides information on the dust size distribution.”

IUVS is one of MAVENS’s nine science sensors in three instrument suites targeted to study why and exactly when did Mars undergo the radical climatic transformation.

How long will MAVEN make observations of Comet C/2013 A1 Siding Spring?

“We’ll be using IUVS to look at the comet itself, about 2 days before comet nucleus closest approach.”

“In addition, for about two days before and two days after nucleus closest approach, we’ll be using one of our “canned” sequences to observe the upper atmosphere and solar-wind interactions.”

“This will give us a detailed look at the upper atmosphere both before and after the comet, allowing us to look for differences.”

Describe the risk that Comet Siding Spring poses to MAVEN, and the timing?

“We have the encounter with Comet Siding Spring about 2/3 of the way through the commissioning phase we call transition.”

“We think that the risk to the spacecraft from comet dust is minimal, but we’ll be taking steps to reduce the risk even further so that we can move on toward our science mission.”

“Throughout this entire period, though, spacecraft and instrument health and safety come first.”

What’s your overall hope and expectation from the comet encounter?

“Together [with the other orbiters], I’m hoping it will all provide quite a data set!

“From Mars, the comet truly will fill the sky!” Jakosky gushed.

The comet’s nucleus will fly by Mars at a distance of only about 82,000 miles (132,000 kilometers) at 2:28 p.m. ET (18:28 GMT) on Oct. 19, 2014. That’s barely 1/3 the distance from the Earth to the Moon.

What’s the spacecraft status today?

“Everything is on track.”

The $671 Million MAVEN spacecraft’s goal is to study Mars upper atmosphere to explore how the Red Planet lost most of its atmosphere and water over billions of years and the transition from its ancient, water-covered past, to the cold, dry, dusty world that it has become today.

MAVEN soared to space over nine months ago on Nov. 18, 2013 following a flawless blastoff from Cape Canaveral Air Force Station’s Space Launch Complex 41 atop a powerful Atlas V rocket and thus began a 10 month interplanetary voyage from Earth to the Red Planet.

It is streaking to Mars along with ISRO’s MOM orbiter, which arrives a few days later on September 24, 2014.

So far it has traveled 95% of the distance to the Red Planet, amounting to over 678,070,879 km (421,332,902 mi).

As of Sept. 4, MAVEN was 205,304,736 km (127,570,449 miles) from Earth and 4,705,429 km (2,923,818 mi) from Mars. Its Earth-centered velocity is 27.95 km/s (17.37 mi/s or 62,532 mph) and Sun-centered velocity is 22.29 km/s (13.58 mi/s or 48,892 mph) as it moves on its heliocentric arc around the Sun.

One-way light time from MAVEN to Earth is 11 minutes and 24 seconds.

NASA’s large space station robot now has legs and a plan to (eventually) head outside to do spacewalks, to replace some of the more routine tasks taken on by astronauts. Robonaut 2 has actually been on the International Space Station since 2011, but only received the extra appendages in the past few days.

The robot is capable of flipping switches, moving covers and with the legs, clamping on to spots around the station. Check out the videos below to see some of the stuff that it is already capable of. It’s both creepy and amazing to watch.

ExoMars Hunting: Where Should The European Rover Land?

Picking a landing site on Mars is a complex process. There’s the need to balance scientific return with the capabilities of whatever vehicle you’re sending out there. And given each mission costs millions (sometimes billions) of dollars — and you only get one shot at landing — you can bet mission planners are extra-cautious about choosing the right location.

A recent paper in Eos details just how difficult it is to choose where to put down a rover, with reference to the upcoming European ExoMars mission that will launch in 2018.

In March, scientists came together to select the first candidate landing sites and came up with four finalist locations. The goal of ExoMars is to look for evidence of life (whether past or present) and one of its defining features is a 2-meter (6.6-foot) drill that will be able to bore below the surface, something that the NASA Curiosity rover does not possess.

“Among the highest-priority sites are those with subaqueous sediments or hydrothermal deposits,” reads the paper, which was written by Bradley Thomson and Farouk El-Baz (both of Boston University). Of note, El-Baz was heavily involved in landing site selection for the Apollo missions.

“For example,” the paper continues, “some of the clearest morphological indicators of past aqueous activity are channel deposits indicative of past fluvial activity or the terminal fan, or delta deposits present within basins.”

But no landing site selection is perfect. The scientists note that Curiosity, for all of its successes, seems unlikely to achieve its primary science objectives in its two-year mission because the commissioning phase took a while, and the rover moves relatively slowly.

That said, NASA has argued that the rover achieved its goal of finding past habitable environments already, with discoveries such as extensive evidence of a past potentially life-bearing lake now called Yellowknife Bay.

Outcrops in Yellowknife Bay are being exposed by wind driven erosion. These rocks record superimposed ancient lake and stream deposits that offered past environmental conditions favorable for microbial life. This image mosaic from the Mast Camera instrument on NASA's Curiosity Mars rover shows a series of sedimentary deposits in the Glenelg area of Gale Crater, from a perspective in Yellowknife Bay looking toward west-northwest.  The "Cumberland" rock that the rover drilled for a sample of the Sheepbed mudstone deposit (at lower left in this scene) has been exposed at the surface for only about 80 million years.

What could change the area of the landing could be using different types of entry, descent and landing technologies, the authors add. If the parachute opened depending on how far the spacecraft was from the ground — instead of how fast it was going — this could make the landing ellipse smaller.

This could place the rover “closer to targets of interest that are too rough for a direct landing and reducing necessary traverse distances,” the paper says.

You can read the paper in its entirety at this link, which also goes over the history of selecting landing sites for the Apollo missions as well as the Mars Exploration Rovers (Spirit and Opportunity).

Memory Problems On Mars Will Force Opportunity Rover Reformat From Earth

NASA’s Opportunity rover, which has been roaming Mars for more than 10 Earth years, requires a flash memory reformat to keep doing science on the Red Planet, the agency wrote in an update Aug. 29 along with its intentions for making that possible quickly.

“Flash-memory induced resets have increased in occurrence, preventing meaningful science until this problem can be corrected,” NASA said on the Opportunity website. “The project is developing plans to reformat the flash file system to correct the problem.”

The agency has experience in doing this procedure as they successfully ran it on the twin Spirit rover five years ago, before the rover got stuck in sand and died. A separate update on the Jet Propulsion Laboratory website noted there have been more than a dozen incidents on Opportunity in the past month, and it takes a day or two to recover from each one.

Flash memory, the update added, is useful because data remains on the rover even if it is turned off. But after 10 years of using the cells on Opportunity’s flash memory, the agency suspects that these cells are starting to wear out. “Reformatting clears the memory while identifying bad cells and flagging them to be avoided,” the update read.

The procedure will take place early this month. Meanwhile, NASA is flushing the flash memory by sending the data back to Earth — as well as switching the rover to a mode where it doesn’t use flash memory. Just in case the rover resets itself during the procedure, NASA is also changing up Opportunity’s communications to send data more slowly (which makes the rover more resilient to problems, the agency said.)

“The flash reformatting is a low-risk process, as critical sequences and flight software are stored elsewhere in other non-volatile memory on the rover,” stated JPL’s John Callas, project manager for NASA’s Mars Exploration Rover Project.

Opportunity is currently circling the ring of Endeavour crater and is in otherwise excellent health, NASA said. The rover has driven 25.28 miles (40.69 kilometers) since arriving on Mars in January 2004 for what was supposed to be a 90-day mission.

Here’s Your Chance To Send A Message To An Asteroid

What’s your vision for solar system exploration? And how cool would it be to send it literally into the solar system?

NASA is offering its fans the chance to compose a tweet or send a picture showing how we can step out into the cosmos. The best ones among these will be placed aboard a spacecraft that will zoom to an asteroid in 2016.

The “time capsule” will be placed aboard the Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx). If all goes to plan, it will meet with the asteroid Bennu in 2019, pick up a sample and then return it to Earth in 2023.

And by the way, you can also send your name to Bennu via this form (a joint initiative of NASA and the Planetary Society.) Seems a good chance to get your name off of Earth, until the time when space travel becomes affordable to ordinary citizens.

For more details about the tweets and images time capsule, visit this NASA website. Make sure to submit your message before Sept. 30.
