A Hybrid Solar Eclipse Seen From Earth… and Space

The final eclipse for 2013 was a grand event, witnessed across the Atlantic and the heart of Africa this past Sunday. Like so many other photographers along the North American east coast, we were at the ready to greet the partially eclipsed Sun at dawn. And as the shadow of the Moon touched down, teams on land, air and sea were ready to meet with the fleeting umbra as it raced eastward towards sunset over the Horn of Africa region.

But a fleet of spacecraft were also on hand to witness the rare spectacle as well. Turned earthward and sunward, these spacecraft documented not only the passage of the Moon’s shadow over the Earth, but recorded multiple partial solar eclipses from orbit as well.

The first view comes from the Roscosmos Electro-L satellite based in a geostationary orbit over the Indian Ocean:

Electro-L had captured such a view before, during the annular eclipse over Australia earlier this year in May. Roscosmos increased the frame capture rate of Electro-L to twice its usual speed for the sequence. As you watch the Earth pass from a waning gibbous to crescent phase, you can just see the umbra, or central shadow of the Moon, slide into view and come into contact with the sunset terminator over eastern Africa. You can also see the cloud cover that marks the dust storms that plagued eclipse-chasers based around the Lake Turkana region in Kenya.

One of the first public pictures of the umbra of the Moon as seen from space was taken from the Mir space station during a total solar eclipse in 1999. To our knowledge, such a feat has yet to be duplicated aboard the International Space Station. The phase angle of the ISS’s orbit during the eclipse was nearly perpendicular to the Sun-Moon-Earth syzygy, and unfavorable for this particular eclipse.

Thanks to the Russian journalist Vitaliy Egorov for bringing the Electro-L eclipse sequence to the attention of Universe Today!

Next up is a sequence of images from NASA’s Aqua satellite:

Launched in 2002, Aqua is part of the “A-train” (as in “Afternoon”) constellation of Earth-observing satellites. Perched in a low-Earth Sun-synchronous orbit, Aqua caught sight of the umbra of the Moon at around 14:45 UT on Sunday, November 3rd as it raced to make first landfall over the nation of Gabon and awaiting eclipse chasers.

Some Sun observing spacecraft caught sight of the eclipse as well. The European Space Agency’s Proba-2 nabbed three partial solar eclipses from its vantage point in low Earth orbit:

PROBA-2 used its SWAP imager to grab the sequences. Orbiting the Earth once every 99 minutes or 14.5 time a day, these “orbital eclipses” are quick, lasting about 10 minutes each in duration.

Finally, EUMETSAT’s MeteoSat-10 meteorological satellite based in a geostationary orbit over Africa captured an outstanding sequence, showing nearly the entire trek of the umbra across the entire path of the eclipse:

The sequence runs from 7:30 to 18:30 UT on November 3rd. Note how the video shows the shadow fade in and sharpen as the eclipse touches down off of the US East Coast and intensifies from an annular to total along the first 15 seconds of its track, only to speed up and flatten towards sunset over Africa. And all in six seconds!

And back here on Earth, we couldn’t resist stitching together the bounty from our own minor eclipse expedition for a stop-motion view of the partially eclipsed Sun rising over the Vehicle Assembly Building at the Kennedy Space Center in Florida:

We’d like to also mention a photo that isn’t a “solar eclipse seen from space…” Y’know the one, which shows the Earth, the Moon’s shadow, and a totally-eclipsed Sun, against a star dappled Milky Way. We won’t dignify it with a link. This has already been debunked by Bad Astronomer himself Phil Plait, but the bogus pic now seems to make its rounds across ye’ ole Web now during every eclipse. Seriously? Do we all crave “link juice” that bad? There are lots of real awesome eclipse photos out there, from Earth & beyond! Please, do your part to tell that well meaning friend/coworker/relative/stranger on Twitter that this “ultimate eclipse photo…” isn’t.

How rare are hybrid solar eclipses? Well, the next solar eclipse that is both annular and total along its track occurs over southeast Asia on April 20th, 2023. It’s interesting to note that this past weekend’s eclipse may have been the first sunrise solar eclipse over the VAB since it was built in 1966. Eclipses in the same 18 years and 11 days- long saros cycle repeat, but move about 120 degrees westward. Thus, follow an eclipse cycle through a “triple saros”— known as an “Exeligmos,” an ultimate scrabble word if you can land it on a triple word score! —and an eclipse’s geometry will roughly line back up over a 54 year 33 day long span. Saros 143 produced a an eclipse crossing a similar path on October 2nd, 1959 (before the VAB was built!) and will repeat its Atlantic sunrise performance on December 6th, 2067! Let’s see, by then I’ll be…

India’s First Mars Mission Launches Flawlessly on Historic Journey to the Red Planet

India flawlessly launched its first ever mission to Mars today (Nov. 5) to begin a history making ten month long interplanetary voyage to the Red Planet that’s aimed at studying the Martian atmosphere and searching for methane after achieving orbit.

The Mars Orbiter Mission (MOM) thundered to space atop the nations four stage Polar Satellite Launch Vehicle (PSLV) precisely on time at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST) from the Indian Space Research Organization’s (ISRO) Satish Dhawan Space Centre SHAR, Sriharikota, off India’s east coast.

“Our journey to Mars begins now!” announced an elated ISRO Chairman K. Radhakrishnan at the ISRO spaceport during a live broadcast of MOM’s launch from the mission control center. “We achieved orbit and we can all be proud.”

This was the 25th launch of India’s highly reliable 44 meter (144 foot) tall PSLV booster.

The 700,000 pound thrust PSLV rocket launched in its most powerful, extended XL version with six strap on solid rocket motors.

“I’m extremely happy to announce that the PSLV-C25 vehicle has placed the Mars orbiter spacecraft very precisely into an elliptical orbit around Earth of 247 x 23556 kilometers with an inclination of 19.2 degrees,” Radhakrishnan said, after “much meticulous planning and hard work by everyone.”

ISRO announced that MOM separated from the PSLV 4th stage as planned some 44 minutes after liftoff and that the solar panels successfully deployed.

Confirmation of the 4th stage ignition and spacecraft separation was transmitted by ship-borne terminals aboard a pair of specially dispatched tracking ships – SCI Nalanda and SCI Yamuna – stationed by ISRO in the South Pacific Ocean.

MOM was designed and developed by the Indian Space Research Organization (ISRO) in near record time after receiving approval from the Indian Prime Minister Manmohan Singh in August 2012.

“No mission is beyond our capability”, said Radhakrishnan. “MOM is a huge step taking India beyond Earth’s influence for the first time.”

A series of six burns over the next month will raise the apogee and put MOM on a trajectory for Mars around December 1.

Following a 300 day interplanetary cruise phase, the do or die Mars orbital insertion firing by the main engine on September 24, 2014 will place MOM into an 366 km x 80,000 km elliptical orbit.

If all continues to goes well with MOM, India will join an elite club of 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).

MOM is the first of two new Mars orbiter science probes from Earth blasting off for the Red Planet this November. Half a globe away, NASA’s $671 Million MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from Cape Canaveral, Florida.

The 1,350 kilogram (2,980 pound) MOM orbiter is also known as ‘Mangalyaan’ – which in Hindi means ‘Mars craft.’

Although the main objective is a demonstration of technological capabilities, the probe is equipped with five indigenous instruments to conduct meaningful science – including a multi color imager and a methane gas sniffer to study the Red Planet’s atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both geological and biological sources – and could be a potential marker for the existence of Martian microbes.

MOM’s 15 kg (33 lb) science suite comprises:

MCM: the tri color Mars Color Camera images the planet and its two tiny moons, Phobos and Deimos

LAP: the Lyman Alpha Photometer measures the abundance of hydrogen and deuterium to understand the planets water loss process

TIS: the Thermal Imaging Spectrometer will map surface composition and mineralogy

MENCA: the Mars Exospheric Neutral Composition Analyser is a quadrapole mass spectrometer to analyze atmospheric composition

MSM: the Methane Sensor for Mars measures traces of potential atmospheric methane down to the ppm level.

Scientists will be paying close attention to whether MOM detects any atmospheric methane to compare with measurements from NASA’s Curiosity rover – which found ground level methane to be essentially nonexistent – and Europe’s upcoming 2016 ExoMars Trace Gas Orbiter.

MOM and MAVEN will arrive nearly simultaneously in Mars orbit next September – joining Earth’s invasion fleet of five operational orbiters and intrepid surface rovers currently unveiling the mysteries of the Red Planet.

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.

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.

The $69 Million ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for about six to ten months and hopefully much longer.

Stay tuned here for continuing MAVEN and MOM news and my MAVEN launch reports from on site at the Kennedy Space Center press center.

A Dark and Dusty Avalanche on Mars

Loose soil, dust and rock stains an icy cliffside on Mars (NASA/JPL/University of Arizona)

Mars may be geologically inactive but that doesn’t mean there’s nothing happening there — seasonal changes on the Red Planet can have some very dramatic effects on the landscape, as this recent image from the HiRISE camera shows!

The full extent of the 1000-meter-long dusty landslide (NASA/JPL/University of Arizona)
The full extent of the 1000-meter-long dusty landslide (NASA/JPL/University of Arizona)

When increasing light from the springtime Sun warms up the sides of sheer cliffs made from countless layers of water and carbon dioxide ice near Mars’ north pole, some of that CO2 ice sublimes, sending cascades of loose soil and dust down to the terraced base below. This uncovered material stains the frost-covered polar surface dark, outlining the paths of avalanches for HiRISE to easily spot from orbit. (See the original HiRISE image here.)

Circling Mars since March 2006, the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter has even captured some of these polar landslides in action.

The rust-colored avalanche shown above has fallen hundreds of meters from the middle of a layered ice deposit, spreading nearly a kilometer across the frozen ridges at the base of the cliff. The view was acquired on Sept. 13, 2013.

Check out a video explaining this view and the processes that created it below, narrated by Phil Plait (aka the Bad Astronomer).

Mars’ seasonal polar caps are composed primarily of carbon dioxide frost. This frost sublimates (changes from solid directly to gas) in the spring, boosting the pressure of Mars’ thin atmosphere. In the fall the carbon dioxide condenses, causing the polar caps to reach as far as ~55 degrees latitude by late winter. By learning about current processes on a local level we can learn more about how to interpret the geological record of climate changes on Mars. (Source)

MOM is spending her last night on Earth – and she’s a Mind-Blowing Midnight Marvel !

The pride of all India, and everyone’s favorite MOM is healthy and set to embark on the nation’s first ever interplanetary voyage of exploration. She aims to conduct a detailed study of the Martian atmosphere and sniff for methane – a potential indicator for life.

The Mars Orbiter Mission (MOM) was designed and developed by the Indian Space Research Organization (ISRO) which is broadcasting a live webcast of the launch starting at 14:00 hrs IST, 3:30 a.m. EST at – http://isro.org/

“All vehicle systems have been switched ON,” as of now, says ISRO.

Now less than 8 hours from blastoff, the PSLV-C25 booster rocket is fully fueled and poised to streak from ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, located on India’s east coast in Andhra Pradesh state.

If all goes well with MOM, India joins an elite club of 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).

Reaching Mars successfully is an enormous technological challenge. More than half of all Earth’s attempts have failed. But those who fail to ‘dare mighty things’ are doomed to timidity and ignominy.

ISRO reports that the weather outlook is favorable for an on time launch on Nov 05, 2013 at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST).

“Weather Forecast for launch day based on today’s image from Kalpana Meteorological Satellite: Early morning, cloudy and low probability of Rain, No severe weather expected. During launch window – partly cloudy weather and no rain is expected.”

“Looks like we are heading towards a bright and sunny day for the launch,” says ISRO.

Just hours ago the final loading of propellants into the rocket’s liquid fueled second stage (PS2) with highly toxic nitrogen tetroxide and hydrazine was satisfactorily completed.

The launch gantry has been retracted to a distance of 50 meters and the 44 meter (144 foot) tall four stage PSLV booster stands at the ready under the gaze of the starry night.

Two tracking ships – SCI Nalanda and SCI Yamuna – have been deployed to the Indian Ocean.

They are now in position to relay critical in flight telemetry during the ignition of the PSLV-C25 fourth stage and the spacecraft’s separation from the rocket at T plus 44 minutes.

“For about ten minutes between the separation of third stage of PSLV and ignition of fourth stage the vehicle will not be visible from any ground stations as will be evident in the Live telecast,” says ISRO.

And the launch team is leaving no stone unturned to ensure success!

“As the country gets embraced in deep sleep – don’t forget a few hundred tireless minds at ISRO – rock-steady on their consoles and keeping their strict vigil on the several health parameters of the rocket and the MoM spacecraft,” said ISRO in a statement.

And here’s a poetic tribute to MOM from ISRO

1391674_1392844634286810_1481308204_n

MOM is the first of two new Mars orbiter science probes from Earth set to blast off for the Red Planet this November. On the other side of Earth, NASA’s MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from Cape Canaveral, Florida.

The 1,350 kilogram (2,980 pound) MOM orbiter is also known as‘Mangalyaan’ – which in Hindi means ‘Mars craft.’

‘Mangalyaan’ is outfitted with an array of five indigenous science instruments including a multi color imager and a methane gas sniffer to study the Red Planet’s atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both geological and biological sources – and could be a potential marker for the existence of Martian microbes.

The PSLV will inject MOM into an initially elliptical Earth parking orbit of 248 km x 23,500 km. A series of six orbit raising burns will eventually place MOM on a trajectory to Mars around December 1.

A complex network of ground stations, as indicated in the image, has been laid out for keeping an eye on the various phases of PSLV-C25/ ISRO's Mars Orbiter Mission, including the launch, Earth bound maneuvers, Heliocentric phase as well as the Martian phase.  Additionally, two ship borne terminals have also been deployed in the southern Pacific Ocean to cover critical events during the launch phase. After satellite separation from the launch vehicle, the Spacecraft  operations are controlled from the Spacecraft Control Centre of ISRO Telemetry, Tracking And Command Network (ISTRAC) in Bangalore.

The countdown has commenced and the excitement is building for India’s Mars Orbiter Mission (MOM) – which will conduct a detailed study of the Martian atmosphere and is the nation’s first ever mission to the Red Planet.

The 56 hour 30 min countdown started at 6:06 a.m. IST today (Nov. 3), according to an official statement from the Indian Space Research Organization (ISRO) leading to liftoff on Tuesday, Nov 5, from a seaside launch pad in Sriharikota, India.

MOM is the first of two new Mars orbiter science probes from Earth set to blast off for the Red Planet this November. Half a globe away, NASA’s MAVEN orbiter remains on target to launch barely two weeks after MOM on Nov. 18 – from the Florida Space Coast.

ISRO will broadcast the momentous MOM launch live at – starting at 14:00 hrs IST.

“The Launch Authorisation Board has approved & cleared the PSLV-C25/Mars Orbiter Mission launch on Nov 05, 2013 at 14:38 hrs IST (9:08 UTC, 4:08 a.m. EST)” from the state-of-the-art Satish Dhawan Space Centre SHAR, Sriharikota, located on India’s east coast in Andhra Pradesh state.

MOM is on schedule to lift off atop the powerful, extended XL version of India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV-C25).

Fueling of the PSLV-C25/Mars Orbiter Mission rocket stages is now in progress following a completely successful dress rehearsal and launch countdown exercise completed on Oct. 31.

“The filling of propellants into the Roll Control Thrusters as well as the Fourth stage of the PSLV C25 rocket [with mixed nitrogen oxides and monomethylhydrazine] is completed,” ISRO declared a short while ago.

903629_10151441040913224_1192855533_o

During the dress rehearsal the vehicle systems were powered, the health was normal and the spacecraft & launch vehicle integrated level checks were completed.

Two tracking ships have been deployed to the Indian Ocean to relay critical in flight telemetry.

The 44 meter (144 ft) PSLV will launch MOM into an initially elliptical Earth parking orbit of 248 km x 23,500 km. A series of six orbit raising burns will eventually dispatch MOM on a trajectory to Mars around December 1.

Following a 300 day interplanetary cruise phase, the do or die Mars orbital insertion engine will fire on September 21, 2014 and place MOM into an 366 km x 80,000 km elliptical orbit.

MOM arrives about the same time as NASA’s MAVEN orbiter. They will significantly bolster Earth’s armada of five operational orbiters and surface rovers currently investigating the Red Planet.

MAVEN and MOM will “work together” to help solve the mysteries of Mars atmosphere, the chief MAVEN scientist told Universe Today.

“We plan to collaborate on some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

The 1,350 kilogram (2,980 pound) MOM orbiter, also known as ‘Mangalyaan’, is the brainchild of ISRO.

‘Mangalyaan’ is outfitted with an array of five indigenous science instruments including a multi color imager and a methane gas sniffer to study the Red Planet’s atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both biological and geological sources.

Scientists will be paying close attention to whether MOM detects any atmospheric methane to compare with measurements from NASA’s Curiosity rover – which found ground level methane to be essentially nonexistent – and Europe’s upcoming 2016 ExoMarsTrace Gas Orbiter.

Although there are no NASA instruments on board MOM, NASA is providing key communications and navigation support to ISRO and MOM through the agency’s trio of huge tracking antennas in the Deep Space Network (DSN).

“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,” MAVEN’s PI Jakosky told me.

“We agreed on the value of collaboration and will hold real discussions at a later time,” he noted.

India would become only the 4th nation or entity from Earth to survey Mars up close with spacecraft, following the Soviet Union, the United States and the European Space Agency (ESA)- if all goes well.

Past attempts to reach the Red Planet from both China and Japan have unfortunately failed.

Some observers speculate that India’s MOM mission will ignite a new Asian Space Race.

The $69 Million ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for at least six months and hopefully much longer.

Long live MOM !

The Eerie Music of Interstellar Space

While it’s true that there’s no air to carry sound in space, starship explosions would be strangely silent and no one can hear you scream, this latest Science @ NASA video reminds us that “space can make music, if you know how to listen.”

And the “how” in this case is with the Plasma Wave Science Experiment aboard the Voyager 1 spacecraft, which is now playing the sounds of interstellar space — with a little help from University of Iowa physics professor and experiment principal investigator Don Gurnett. Watch the video above for a front-row seat (and read more about Voyager’s historic crossing of the heliosphere here.)

KENNEDY SPACE CENTER, FL – Orion, the first NASA spaceship that will ever carry Earthlings to deep space destinations, has at last been “powered on” for the first time at the manufacturing facility at the Kennedy Space Center (KSC) where it’s the centerpiece of a beehive humming 24/7 with hi tech processing activities in all directions.

“Power On” marks a major milestone ahead of the maiden space bound Orion test flight dubbed “EFT-1” – now at T-Minus 1 year and counting!

NASA and prime contractor Lockheed Martin recently granted Universe Today an exclusive in depth inspection tour of the impressive Orion EFT-1 crew module, service module and associated hardware destined for the crucial unmanned test flight slated for liftoff from Cape Canaveral in September 2014.

“We are moving fast!” said Jules Schneider, Orion Project manager for Lockheed Martin at KSC, during an exclusive interview with Universe Today as we spoke beside the Orion EFT-1 spacecraft inside the clean room.

“We are working 24 hours a day, 7 days a week,” Schneider told me.

Some 200 people are actively employed on building Orion by Lockheed Martin at the Kennedy Space Center.

“There are many significant Orion assembly events ongoing this year,” said Larry Price, Orion deputy program manager at Lockheed Martin, in an interview with Universe Today at Lockheed Space Systems in Denver.

“This includes the heat shield construction and attachment, power on, installing the plumbing for the environmental and reaction control system, completely outfitting the crew module, attached the tiles, building the service module and finally mating the crew and service modules (CM & SM),” Price told me.

Orion is a state of the art crew capsule that will ultimately enable astronauts to fly to deep space destinations including the Moon, Asteroids, Mars and beyond – throughout our solar system.

And Universe Today has had a front row seat.

I have been very fortunate to periodically visit Orion up close over the past year and half to evaluate the testing and assembly progress inside the Operations and Checkout Building at KSC where the vehicle is now rapidly coming together, since the bare bones pressure vessel arrived to great fanfare in June 2012.

For the first time Orion looked to my eyes like a real spaceship, rather than the backbone shell outfitted with hundreds of important test harnesses, strain gauges and wiring to evaluate its physical and structural integrity.

Engineers and technicians at KSC have removed the initial pressure testing gear and are now installing all the flight systems and equipment – such as avionics, instrumentation, flight computers, thrusters, wiring, plumbing, heat shield and much more – required to transform the initial empty shell into a fully functioning spacecraft.

“The Orion skeleton was here before. Now we are putting in all of the other systems,” Schneider explained to me.

“We are really busy.”

“So far over 66,000 Orion parts have been shipped to KSC from over 40 US states,” Price explained.

The heat shield was due to arrive soon and technicians were drilling its attachment ring holes as I observed the work in progress.

“The propulsion, environmental control and life support systems are now about 90% in. The ammonia and propylene glycol loops for the thermal control system are in. Many of the flight harnesses are installed.”

“All of the reaction control thrusters are in – fueled by hydrazine – as well as the two hydrazine tanks and a helium tank. Altogether there are 12 hydrazine pods with two thrusters each,” Schneider elaborated.

The power distribution unit (PDU) – which basically functions as Orion’s computer brains – was installed just prior to my visit. All four PDU’s – which issue commands to the vehicle – were built by Honeywell.

Technicians were actively installing fiber optic and coaxial cables as I watched. They also were conducting leak tests on the environmental control coolant (ECLS) systems which had to be completed before the ‘power on’ testing could begin – in order to cool the avionics systems.

Thermal protection system (TPS) tiles were being bonded to the back panels which ring Orion. The TPS panels get attached early in 2014.

“This is real stuff,” said Schneider gleefully.

NASA says that “the preliminary data indicate Orion’s vehicle management computer, as well as its innovative power and data distribution system — which use state-of-the-art networking capabilities — performed as expected” during the initial crew module power on.

About two months or so of power on functional testing of various systems will follow.

Just like the configuration used in the Apollo era, the Orion crew module will sit atop a service module – and that work is likewise moving along at a rapid clip.

“The Orion service module (SM) is also almost complete,” Schneider said as he showed me the service module structure.

“Structurally the SM is 90% done. The active thermal control system is in and all the fluid systems are welded in and pressure tested.”

Orion EFT-1 will blastoff atop a mammoth United Launch Alliance Delta IV Heavy rocket – the most powerful booster in America’s arsenal since the shuttle’s retirement in 2011.

The crew module and service module (CM/SM) will be mated inside the O&C and then be placed onto a mission adapter that eventually attaches to the top of the Delta IV Heavy booster.

They will be mated at the exact same spot in the O&C Building where the Apollo era command and service modules were stacked four decades ago.

Currently, the schedule calls for the Orion CM/SM stack to roll out to Kennedy’s Payload Hazardous Services Facility (PHSF) for servicing and fueling late this year, said Larry Price.

After that the CM/SM stack is transported to the nearby Launch Abort System Facility (LASF) for mating to the emergency Launch Abort System (LAS).

All that work could be done around March 2014 so that ground operations preparing for launch can commence, according to Price.

“In March 2014 we’ll be ready for ground ops. The normal launch processing flow starts in June 2014 leading to Orion’s launch from pad 37 in September 2014.”

“It’s very exciting and a tribute to the NASA and contractor teams,” Price said.

The 2014 uncrewed flight will be loaded with a wide variety of instruments to evaluate how the spacecraft behaves during launch, in space and then through the searing heat of reentry.

The two-orbit, four- hour 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.

Although the mission will only last a few hours it will be high enough to send the vehicle plunging back into the atmosphere and a Pacific Ocean splashdown to test the craft and its heat shield at deep-space reentry speeds of 20,000 mph and endure temperatures of 4,000 degrees Fahrenheit – like those of the Apollo moon landing missions.

The EFT-1 mission will provide engineers with critical data about Orion’s heat shield, flight systems and capabilities to validate designs of the spacecraft, inform design decisions, validate existing computer models and guide new approaches to space systems development. All these measurements will aid in reducing the risks and costs of subsequent Orion flights before it begins carrying humans to new destinations in the solar system.

“The Orion hardware and the Delta IV Heavy booster for the EFT-1 launch are on target for launch in 2014,” Scott Wilson, NASA’s Orion Manager of Production Operations, told Universe Today in an interview.

MAVEN and MOM Missions from NASA and India Plan Martian Science Collaboration in Orbit

MAVEN is NASA’s next Mars orbiter and is due to blastoff on Nov. 18 from Cape Canaveral, Florida. It will study the evolution of the Red Planet’s atmosphere and climate.

After years of hard work by dedicated science and engineering teams, a new pair of Mars orbiter science missions from Earth are in the final stages of prelaunch processing and are nearly set to blast off for the Red Planet in November.

If all goes well, NASA’s MAVEN orbiter and India’s MOM (Mars Orbiter Mission) will “work together” to help solve the mysteries of Mars atmosphere, the chief MAVEN scientist told Universe Today at a NASA briefing today (Oct. 28).

“We plan to collaborate on some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

MAVEN and MOM will join Earth’s armada of five operational orbiters and surface rovers currently exploring the Red Planet.

MOM is India’s first mission to Mars. Its also first in line to this year’s Martian on ramp and is slated to lift off in barely one week on Nov. 5 atop the most powerful version of the Polar Satellite Launch Vehicle (PSLV) rocket from a seaside launch pad in Srihanikota, India.

The 1,350 kilogram (2,980 pound) MOM orbiter, also known as ‘Mangalyaan’, is the brainchild of ISRO, the Indian Space Research Organization.

NASA’s Mars Atmosphere and Volatile EvolutioN Mission (MAVEN) spacecraft launches in three weeks on Nov. 18 atop a United Launch Alliance Atlas V 401 rocket from a seaside pad on Cape Canaveral Air Force Station, Florida.

Both MAVEN and MOM will study the Red Planets atmosphere. Although they are independent and carrying different science payloads the two missions do have some common goals.

“There are some overlapping objectives between MAVEN and MOM,” Jakosky said.

“We have had some discussions with the MOM science team.”

Both orbiters are due to arrive at Mars in September 2014 after 10 month interplanetary cruises and will enter different elliptical orbits after main engine braking burns.

MAVEN is the first spacecraft from Earth devoted to investigating and understanding the upper atmosphere of Mars.

The purpose is to study specific processes and determine how and why Mars lost virtually all of its atmosphere billions of years ago and what effect that had on the history of climate change and habitability.

“The major questions about the history of Mars center on the history of its climate and atmosphere and how that’s influenced the surface, geology and the possibility for life,” said Jakosky.

“MAVEN will focus on understanding the history of the atmosphere, how the climate has changed through time, and how that influenced the evolution of the surface and the potential for habitability by microbes on Mars.”

“We don’t know the driver of the change.”

“Where did the water go and where did the carbon dioxide go from the early atmosphere? What were the mechanisms?”

“That’s what driving our exploration of Mars with MAVEN,” said Jakosky.

One of the significant differences between MOM and MAVEN regards methane detection – which is a potential marker for Martian life. Some 90% of Earth’s atmospheric methane derives from living organisms.

MOM has a methane sensor but not MAVEN.

“We just had to leave that one off to stay focused and to stay within the available resources ,” Jakosky told me.

MAVEN carries nine sensors in three instrument suites.

The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.

MOM’s science complement comprises the tri color Mars Color Camera to image the planet and its two moons, Phobos and Deimos; the Lyman Alpha Photometer to measure the abundance of hydrogen and deuterium and understand the planets water loss process; a Thermal Imaging Spectrometer to map surface composition and mineralogy, the MENCA mass spectrometer to analyze atmospheric composition, and the Methane Sensor for Mars to measure traces of potential atmospheric methane down to the ppm level.

“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 told me.

“We agreed on the value of collaboration and will hold real discussions at a later time,” he noted.

NASA is providing key communications and navigation support to ISRO and MOM through the agency’s trio of huge tracking antennas in the Deep Space Network (DSN).

Over the course of its one-Earth-year primary mission, MAVEN will observe all of Mars’ latitudes at altitudes ranging from 93 miles to more than 3,800 miles.

MAVEN will execute five deep dip maneuvers during the first year, descending to an altitude of 78 miles. This marks the lower boundary of the planet’s upper atmosphere.

MAVEN has sufficient fuel reserves on board to continue observations for more than a decade.

The spacecraft will function as an indispensible orbital relay by transmitting surface science data through the “Electra” from NASA’s ongoing Curiosity and Opportunity rovers as well as the planned 2020 rover.

Stay tuned here for continuing MAVEN and MOM news and my launch reports from on site at the Kennedy Space Center press center.

Dream Chaser spaceship test article damaged during 1st Free-Flight Drop Test

The engineering test article of the commercial Dream Chaser spaceship being developed by Sierra Nevada Corp (SNC) suffered some significant damage during its critical 1st ever approach-and-landing (ALT) drop test on Saturday, Oct. 26, in California due to an unspecified type of malfunction with the deployment of the left landing gear.

The Dream Chaser mini-shuttle suffered “an anomaly as it touched down on the Runway 22L at Edwards Air Force Base, Calif.,” according to a post-test statement from NASA.

A report at NASA Spaceflight.com indicated that the Dream Chaser “flipped over on the runway” after touchdown.

The full extent of damage to the winged vehicle or whether it can be repaired and reflown is not known at this time. No photos or details explaining the damage have yet emerged – beyond brief press releases issued by SNC and NASA.

The performance of the vehicles’ nose skid, brakes, tires and other flight systems is being tested to prove that it can safely land an astronaut crew returning from the space station after surviving the searing heat of re-entry from Earth orbit.

This initial atmospheric drop test was conducted in an automated mode. There was no pilot on board and no one was hurt on the ground.

“No personnel were injured. Damage to property is being assessed,” said NASA. “Edwards Air Force Base emergency personnel responded to scene as a precaution.

“Support personnel are preparing the vehicle for transport to a hangar.”

Dream Chaser is one of three private sector manned spaceships being developed with funding from NASA’s commercial crew program known as Commercial Crew Integrated Capability (CCiCap) initiative to develop a next-generation crew transportation vehicle.

The NASA seed money aims at restoring America’s manned spaceflight access to low Earth orbit and the International Space Station (ISS) – perhaps by 2017 – following the forced shutdown of the Space Shuttle program in 2011.

Until one of the American commercial space taxis is ready for liftoff, NASA is completely dependent on the Russian Soyuz capsule for astronaut rides to the ISS at a cost of roughly $70 million per seat.

SNC was awarded $227.5 million in the current round of NASA funding and must complete specified milestones including up to five ALT drop tests to check the aerodynamic handling.

To date this test vehicle has successfully accomplished a series of runway tow and airborne captive carry tests.

Development of crew versions of the SpaceX Dragon and Boeing CST-100 capsules are also being funded by NASA’s commercial crew program office.

Dream Chaser can carry a crew of up to seven and is the only reusable, lifting body shuttle type vehicle with runway landing capability among the three competitors.

During Saturday’s test, SNC was performing the first in a series of free-flight approach-and-landing tests with the Dream Chaser prototype test vehicle known as the ETA.

The prototype spaceship was released as planned from its carrier aircraft, an Erickson Air-Crane helicopter, at approximately 11:10 a.m. Pacific Standard Time (2:10 p.m. EDT), said SNC in a statement.

The post release flare and touchdown appeared normal at first until the left landing gear deployment failed at some point after runway touchdown.

“Following release, the Dream Chaser spacecraft automated flight control system gently steered the vehicle to its intended glide slope. The vehicle adhered to the design flight trajectory throughout the flight profile. Less than a minute later, Dream Chaser smoothly flared and touched down on Edwards Air Force Base’s Runway 22L right on centerline,” according to the SNC press release.

SNC went on to say that reviews are in progress to determine the cause of the landing gear failure.

“While there was an anomaly with the left landing gear deployment, the high-quality flight and telemetry data throughout all phases of the approach-and-landing test will allow SNC teams to continue to refine their spacecraft design. SNC and NASA Dryden are currently reviewing the data. As with any space flight test program, there will be anomalies that we can learn from, allowing us to improve our vehicle and accelerate our rate of progress.”

The engineering test article (ETA) is a full sized vehicle.

Dream Chaser is a reusable mini shuttle that launches from the Florida Space Coast atop a United Launch Alliance Atlas V rocket and lands on the shuttle landing facility (SLF) runway at the Kennedy Space Center, like the space shuttle.

“It’s not outfitted for orbital flight. It is outfitted for atmospheric flight tests,” said Marc Sirangelo, Sierra Nevada Corp. vice president and SNC Space Systems chairman told Universe Today previously.

“The best analogy is it’s very similar to what NASA did in the shuttle program with the Enterprise, creating a vehicle that would allow it to do significant flights whose design then would filter into the final vehicle for orbital flight,” Sirangelo told me.

We’ll provide further details as they become known.

Cargo resupply ships are vital for space exploration. These days they bring food, experiments and equipment to astronauts on the International Space Station. And in recent years, it hasn’t just been government agencies sending these things up; SpaceX’s Dragon spacecraft and (just this week) Orbital Sciences’ Cygnus spacecraft brought up cargo of their own to station in recent months.

NASA just published a brief timeline of (real-life) cargo spacecraft, so we thought we’d adapt that information in pictorial form. Here are some of the prominent members of that elite group. Did we miss anything? Let us know in the comments.
