When you look up at the night sky, assuming conditions are just right, you might just catch a glimpse of a faint, white band reaching across the heavens. This band, upon closer observation, looks speckled and dusty, filled with a million tiny points of light and halos of glowing matter. What you are seeing is the Milky Way, something that astronomers and stargazers alike have been staring up at since the beginning of time.
But just what is the Milky Way? Well, simply put, it is the name of the barred spiral galaxy in which our solar system is located. The Earth orbits the Sun in the Solar System, and the Solar System is embedded within this vast galaxy of stars. It is just one of hundreds of billions of galaxies in the Universe, and ours is called the Milky Way because the disk of the galaxy appears to be spanning the night sky like a hazy band of glowing white light.

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.
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.

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 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.

The November 3, 2013 partial solar eclipse with mirage from Sullivan's Island, South Carolina. Credit and copyright: Jeff Jackson
Many lucky people around the world were treated to a an unusual “hybrid” solar eclipse today — so called because the extent to which the Sun was blocked out varied around the world. Those along North America’s east coast and the northern half of South America saw a brilliant Sun partially eclipsed by the Moon just at dawn, as in our lead image from South Carolina, USA. But regions like equatorial Africa had a total eclipsed Sun for about a minute, while those in southern Europe, the Middle East, were able to see an “annular” or partial, eclipse. This type of variable eclipse is rare — the last time one occurred was Nov. 20, 1854 and the next one won’t happen until Oct. 17, 2172! This was also the last eclipse of the year, and photographers were out to capture the views.
UPDATE: We’ve now added more images, including this new one from Uganda that shows totality:

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 bringing Orion to life. Lots of flight hardware has now been installed.”

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

While many are anticipating seeing Comet ISON, there’s more in the sky these days than just one comet. There are actually four comets now in the skies in the mornings — in addition to ISON, there’s comets 2013 R1 Lovejoy, 2P/Encke and 2012 X1 LINEAR! Unfortunately, none of these are visible to the naked eye — yet anyway.
Here are some great recent images and video of these comet taken by amateur astrophotographers. Above is Comet Lovejoy, just taken by Justin Ng from Singapore . “Comet Lovejoy will share the same part of the sky as Comet ISON this month and it presents a cool astrophotography opportunity for skywatchers and astronomers,” Justin told Universe Today via email. “This image is a result of stacking 9 images together and each image was captured using a 3 inch telescope at 5 minutes exposure time for about an hour before dawn.”
