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.

The Expedition 37 crew onboard the International Space Station closed the hatch and said goodbye to the ATV-4 “Albert Einstein” cargo ship early this morning, Oct. 28. Europe’s 4th Automated Transfer Vehicle undocked at 08:55 UTC (4:55 a.m. EDT). The cargo carrier was filled with trash and it will be deorbited on Nov. 2 for a destructive entry back into the Earth’s atmosphere over the Pacific Ocean. ATV-4 has been at the ISS since June 15, delivering more than 7 tons of food, fuel and supplies. Its departure helps prepare for more action at the ISS: the current Soyuz spacecraft docked at the station will be moved to a different location so that a new Soyuz can dock with three new crew members. The Soyuz TMA-11M is scheduled to launch on Nov. 6, 2013 with the Expedition 38/39 crew of Rick Mastracchio, Koichi Wakata, Mikhail Tyurin.

Some images of the undocking, below:

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.

Dream Chaser awaits launch atop United Launch Alliance Atlas V rocket

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.

See below a gallery of Earth from Juno[/caption]

During a crucial speed boosting slingshot maneuver around Earth on Oct. 9, NASA’s Jupiter-bound Juno probe snapped a dazzling gallery of portraits of our Home Planet over the South American coastline and the Atlantic Ocean. See our mosaics of land, sea and swirling clouds above and below, including several shown in false color.

But an unexpected glitch during the do or die swing-by sent the spacecraft into ‘safe mode’ and delayed the transmission of most of the raw imagery and other science observations while mission controllers worked hastily to analyze the problem and successfully restore Juno to full operation on Oct. 12 – but only temporarily!

Because less than 48 hours later, Juno tripped back into safe mode for a second time. Five days later engineers finally recouped Juno and it’s been smooth sailing ever since, the top scientist told Universe Today.

“Juno is now fully operational and on its way to Jupiter,” Juno principal investigator Scott Bolton told me today. Bolton is from the Southwest Research Institute (SwRI), San Antonio, Texas.

“We are completely out of safe mode!”

With the $1.1 Billion Juno probe completely healthy once again and the nail-biting drama past at last, engineers found the time to send the stored photos and research data back to ground station receivers.

“The science team is busy analyzing data from the Earth flyby,” Bolton informed me.

The amateur image processing team of Ken Kremer and Marco Di Lorenzo has stitched together several portraits from raw images captured as Juno sped over Argentina, South America and the South Atlantic Ocean and within 347 miles (560 kilometers) of the surface. We’ve collected the gallery here for all to enjoy.

Several portraits showing the swirling clouds and land masses of the Earth’s globe have already been kindly featured this week by Alan Boyle at NBC News and at the Daily Mail online.

Raw images from the Junocam camera are collected in strips – like a push broom. So they have to be carefully reconstructed and realigned to match up. But it can’t be perfect because the spacecraft is constantly rotating and its speeding past Earth at over 78,000 mph.

So the perspective of Earth’s surface features seen by Junocam is changing during the imaging.

And that’s what is fascinating – to see the sequential view of Earth’s beautiful surface changing as the spacecraft flew over the coast of South America and the South Atlantic towards Africa – from the dayside to the nightside.

It’s rare to get such views since only a few spacecraft have swung by Earth in this manner – for example Galileo and MESSENGER – on their way to distant destinations.

Coincidentally this week, the Cygnus cargo carrier departed the ISS over South America.

Fortunately, the Juno team knew right from the start that the flyby of Earth did accomplish its primary goal of precisely targeting Juno towards Jupiter – to within 2 kilometers of the aim point, despite going into safe mode.

“We are on our way to Jupiter as planned,” Juno Project manager Rick Nybakken, told me in a phone interview soon after the flyby of Earth. Nybakken is from NASA’s Jet Propulsion Lab in Pasadena, CA.

“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is,” he said.

It also accelerated the ships velocity by 16,330 mph (26,280 km/h) – thereby enabling Juno to be captured into polar orbit about Jupiter on July 4, 2016.

The safe mode did not impact the spacecraft’s trajectory one smidgeon!

It was likely initiated by an incorrect setting for a fault protection trigger for the spacecraft’s battery when Juno was briefly in an eclipse during the flyby.

Nybakken also said that the probe was “power positive and we have full command ability,” while it was in safe mode.

Safe mode is a designated fault protective state that is preprogrammed into spacecraft software in case something goes amiss. It also aims the craft sunwards thereby enabling the solar arrays to keep the vehicle powered.

The Earth flyby maneuver was necessary because the initial Atlas V rocket launch on Aug. 5, 2011 from Cape Canaveral Air Force Station, FL was not powerful enough to place Juno on a direct trajectory flight to Jupiter.

As of today, Juno is more than was 6.7 million miles (10.8 million kilometers) from Earth and 739 million miles (7.95 astronomical units) from Jupiter. It has traveled 1.01 billion miles (1.63 billion kilometers, or 10.9 AU) since launch.

With Juno now on course for our solar system’s largest planet, there won’t be no any new planetary images taken until it arrives at the Jovian system in 2016. Juno will then capture the first ever images of Jupiter’s north and south poles.

We have never seen Jupiter’s poles imaged from the prior space missions, and it’s not possible from Earth.

During a year long mission at Jupiter, Juno will use its nine science instruments to probe deep inside the planet to reveal its origin and evolution.

“Jupiter is the Rosetta Stone of our solar system,” says Bolton. “It is by far the oldest planet, contains more material than all the other planets, asteroids and comets combined and carries deep inside it the story of not only the solar system but of us. Juno is going there as our emissary — to interpret what Jupiter has to say.”

Based on what we’ve seen so far, Junocam is sure to provide spectacular views of the gas giants poles and cloud tops.

Only 982 days to go !

What Caused The Spacesuit Leak? Astronauts Are Working To Hunt That Down

NASA astronauts Mike Hopkins and Karen Nyberg (edge of picture, at left) examine a faulty spacesuit aboard the International Space Station during Expedition 37 in October 2013. In July 2013, Italian astronaut Luca Parmitano had to abort a spacewalk after a water leak arose while wearing the spacesuit. The cause is still under investigation. Credit: NASA/YouTube (screenshot)

Here’s the latest attempt to hunt down the water leak that aborted Luca Parmitano’s spacewalk in July: two astronauts aboard the International Space Station removed and replaced a fan pump and water separator inside the spacesuit earlier this week.

All spacewalks with NASA suits are on hold while the agency investigates the leak, and they have been trying mightily. In late July, then on-station NASA astronaut Chris Cassidy demonstrated how the pool of water spread within the helmet (as you can see in these YouTube videos).

This week, on-orbit NASA astronauts Mike Hopkins and Karen Nyberg delved further. While the astronauts are trained before their missions on some suit repairs, this particular type was not something that was covered before they left Earth. After Mission Control walked them through what to do, the astronauts proceeded cautiously as they did the work, NASA said.

“Our engineering teams have identified several different components of the suit, designing a big fault tree, and this is just one of the components that we think could have contributed to the leak in the suit,” said Alex Kanelakos, an extra-vehicular activity flight controller and astronaut instructor, in a new YouTube video.

“Specifically, the water separator is what we’re concentrating our efforts on today.”

As Kanelakos explained, a motor inside the suit drives the fan pump and water separator. The fan circulates oxygen, and the pump pumps the coolant fluid. The water separator, meanwhile, takes out moisture (water) from the ventilation loop and gas that could be trapped inside the water coolant loop. The dried-out air is then returned to the crew member for breathing, and the cycle continues.

In September, Cassidy told Universe Today that the spacesuit is expected to come back to Earth during a future SpaceX Dragon cargo flight. That type of spacecraft is (unusually among space trucks) designed to survive re-entry in the atmosphere, allowing engineers on the ground to examine the spacesuit after it comes back.

Cassidy added that the situation was serious, and he supported NASA’s decision to end the spacewalk (which he was also participating in.) He didn’t think, however, that Parmitano was in immediate danger of drowning. For his part, Parmitano wrote a blog post on the European Space Agency website after his spacewalk, saying that space is an “inhospitable” arena.

As any astronaut is trained to do, Parmitano did consider other contingencies while the leak was happening, he wrote:

“The only idea I can think of is to open the safety valve by my left ear: if I create controlled depressurisation, I should manage to let out some of the water, at least until it freezes through sublimation, which would stop the flow. But making a ‘hole’ in my spacesuit really would be a last resort,” he wrote.

That fix, however, was not implemented as Parmitano and Cassidy made their way back to the station in time for their crewmates to repressurize the hatch and bring their Italian crewmate safely inside.

Besides investigating the spacesuit, NASA has an ongoing parallel investigation to look at “lessons learned” from the mishap and ways of implementing procedures to stop such an incident from happening again.

Video: Spider Flown in Space Has Trouble Readapting to Gravity

Nefertiti, the "Johnson Jumper" spider hunting for flies inside her habitat on board the International Space Station (ISS). (NASA)

Astronauts have said adapting to weightlessness is much easier than readapting to gravity when they returned to Earth. Muscle weakness, wobbly legs, and feeling like the room is spinning is common after long duration spaceflight, not to mention the long-term issues like bone loss, diminished eyesight, and a heart that has to recondition itself to pump blood harder to overcome gravity. As Canadian Chris Hadfield said, “My body was quite happy in space without gravity.”

It turns out spiders have similar issues. This Phiddipus Johnsoni, or red-backed jumping spider named Nefertiti is shown walking and preying on flies in her habitat while in orbit on the International Space Station and then doing the same while readapting to gravity on Earth. While trying to capture its prey, it ends up flopping awkwardly onto its back. No more flying like SuperSpider.

Nefertiti was in space 100 days in 2012 as part of a student-initiated science experiment of YouTube’s Space Lab, an online video contest. After returning home, this spidernaut was sent to the Smithsonian Institution’s National Museum of Natural History in Washington, D.C. and was part of exhibition of the first jumping spider to survive the trip to space. Unfortunately Nefertiti died just a few days after being sent to the museum.

NASA’s Resilient Opportunity Rover Starts Martian Mountaineering

Opportunity starts Martian Mountaineering
NASA’s Opportunity rover captured this southward uphill panoramic mosaic on Oct. 21, 2013 (Sol 3463) after beginning to ascend the northwestern slope of “Solander Point” on the western rim of Endeavour Crater – her 1st mountain climbing adventure. The northward-facing slope will tilt the rover’s solar panels toward the sun in the southern-hemisphere winter sky, providing an important energy advantage for continuing mobile operations through the upcoming winter.

Story and imagery updated[/caption]

NASA’s super resilient Opportunity robot has begun a new phase in her life on the Red Planet – Martian Mountaineer!

“This is our first real Martian mountaineering with Opportunity,” said the principal investigator for the rover, Steve Squyres of Cornell University, Ithaca, N.Y.

And it happened right in the middle of the utterly chaotic US government shutdown ! – that seriously harmed some US science endeavors. And at a spot destined to become a science bonanza in the months and years ahead – so long as she stays alive to explore ever more new frontiers.

On Oct. 8, mission controllers on Earth directed the nearly decade old robot to start the ascent of Solander Point – the northern tip of the tallest hill she has encountered after nearly 10 Earth years on Mars.

The northward-facing slopes at Solander also afford another major advantage. They will tilt the rover’s solar panels toward the sun in the southern-hemisphere winter sky, providing an important energy boost enabling continued mobile operations through the upcoming frigidly harsh winter- her 6th since landing in 2004.

Opportunity will first explore outcrops on the northwestern slopes of Solander Point in search of the chemical ingredients required to sustain life before gradually climbing further uphill to investigate intriguing deposits distributed amongst its stratographic layers.

The rover will initially focus on outcrops located in the lower 20 feet (6 meters) above the surrounding plains on slopes as steep as 15 to 20 degrees.

At some later time, Opportunity may ascend Solander farther upward, which peaks about 130 feet (40 meters) above the crater plains.

“We expect we will reach some of the oldest rocks we have seen with this rover — a glimpse back into the ancient past of Mars,” says Squyres.

NASA’s powerful Mars Reconnaissance Orbiter (MRO) circling overhead recently succeeded in identifying clay-bearing rocks during new high resolution survey scans of Solander Point!

As I reported previously, the specially collected high resolution observations by the orbiters Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) were collected in August and being analyzed by the science team. They will be used to direct Opportunity to the most productive targets of interest

“CRISM data were collected,” Ray Arvidson told Universe Today. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

“They show really interesting spectral features in the [Solander Point] rim materials.”

The new CRISM survey from Mars orbit yielded mineral maps which vastly improves the spectral resolution – from 18 meters per pixel down to 5 meters per pixel.

This past spring and summer, Opportunity drove several months from the Cape York rim segment to Solander Point.

“At Cape York, we found fantastic things,” Squyres said. “Gypsum veins, clay-rich terrain, the spherules we call newberries. We know there are even larger exposures of clay-rich materials where we’re headed. They might look like what we found at Cape York or they might be completely different.”

Clay minerals, or phyllosilicates, form in neutral water that is more conducive to life.

At the base of Solander, the six wheeled rover discovered a transition zone between a sulfate-rich geological formation and an older formation. Sulfate-rich rocks form in a wet environment that was very acidic and less favorable to life.

Solander Point is located at the western rim of the vast expanse of Endeavour crater – some 22 kilometers (14 miles) in diameter.

Today marks Opportunity’s 3466th Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.

So far she has snapped over 185,200 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 23.89 miles (38.45 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Meanwhile, NASA is in the final stages of processing of MAVEN, the agencies next orbiter.

It is still scheduled to blast off from Cape Canaveral on Nov.18 – see my photos from inside the clean room at the Kennedy Space Center.

MAVEN’s launch was briefly threatened by the government shutdown.

On the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and recently discovered a patch of pebbles formed by flowing liquid water.

Incredible Vertical-Landing Grasshopper Rocket Has Retired

Did you take a moment to look at that August video of the Grasshopper rocket deliberately going sideways and then appearing to hover for a bit before returning to Earth? For more video fodder, there’s also this high-flying test the rocket took in October.

We hope you enjoyed these views, because Grasshopper is being retired. SpaceX now wants to focus its energy and resources on to the larger Falcon 9-R first stage, which should see its first test flight in New Mexico this December.

It sounds like SpaceX would have loved to go further, in a sense. “In some ways we’ve kind of failed on the Grasshopper program because we haven’t pushed it to its limit,” SpaceX president Gwynne Shotwell said at the International Symposium for Personal and Commercial Spaceflight (ISPCS) in New Mexico last week, as reported in the NewSpace Journal. “We haven’t broken it.”

Grasshopper took eight test flights during its flight history, which spanned about a year between September 2012 and October 2013. It was intended to test Vertical Takeoff Vertical Landing technology (VTVL). The strange appearance of a rocket leaving Earth and gently, deliberately touching back down again turned heads — even in the general public.

We have coverage — and videos! — of most of its past test flights here (the dates below are flight dates, not publication dates)

November 1, 2012: Flight to 106 feet (32 meters).
December 17, 2012: Flight to 131 feet (40 meters).
March 7, 2013: Flight to 262.8 feet (80.1 meters).
April 17, 2013: Flight to 820 feet (250 meters).
August 13, 2013: Divert maneuver!
October 13, 2013: Highest test flight yet (2,440 feet or 744 meters).

Most rockets are single-use only and are discarded either in orbit or (better yet, for space debris concerns) are put in a path to burn up in Earth’s atmosphere. SpaceX, however, wants its next-generation Falcon 9 rocket to have a reusable first stage to cut down on launch costs. (Grasshopper was about 10 storeys high, while the Falcon 9 will be about 14 storeys tall when carrying a Dragon spacecraft on board.)

As for the Falcon 9 series, a rocket flight in September delivered its payload (which included the Canadian Cassiope satellite) to space successfully, but faced some technical problems with the upper stage — and the first stage, as the rocket was supposed to be slowed down for splashdown.

As Space News reported, two burns were planned. The first worked, but the second burn took place while the rocket was spinning, which affected the flow of fuel. A picture shown by SpaceX demonstrated the rocket was intact three meters above the ocean, although it did not survive after it hit.

“Between the flights we’ve been doing with Grasshopper and this demonstration that we brought that stage back, we’re really close to full and rapid reuse of stages,” Shotwell said in the report.

Cygnus Commercial Cargo Craft Completes Historic First Flight to Space Station

Commercial space took another major leap forward this morning, Oct 22., when the privately developed Cygnus cargo vehicle undocked from the International Space Station on its historic maiden flight and successfully completed a highly productive month long stay during its demonstration mission – mostly amidst the US government shutdown.

The Cygnus was maneuvered about 10 meters (30 feet) away from the station and held in the steady grip of the stations fully extended robotic arm when astronauts Karen Nyberg and Luca Parmitano unlatched the arm and released the ship into free space at 7:31 a.m. EDT today – signifying an end to joint flight operations.

The next Cygnus resupply vessel is due to blast off in mid-December and is already loaded with new science experiments for microgravity research and assorted gear and provisions.

After the Expedition 37 crew members quickly pulled the arm back to a distance 1.5 meters away from Cygnus, ground controllers issued a planned “abort” command to fire the ships thrusters and safely depart from the massive orbiting lab complex.

“It’s been a great mission. Nice work today!” radioed Houston Mission Control at NASA’s Johnson Space Center.

The vehicles were flying over the Atlantic Ocean and off the east coast of Argentina as Cygnus left the station some 250 miles (400 km) overhead in low Earth orbit.

The event was carried live on NASA TV and Cygnus was seen moving rapidly away.

Barely five minutes later Cygnus was already 200 meters away, appeared very small in the cameras view and exited the imaginary “Keep Out Sphere” – a strictly designated safety zone around the million pound station.

The Cygnus resupply ship delivered about 1,300 pounds (589 kilograms) of cargo, including food, clothing, water, science experiments, spare parts and gear to the six person Expedition 37 crew.

After the crew unloaded all that cargo, they packed the ship with 2,850 pounds of no longer needed trash.

On Wednesday (Oct. 23), a pair of deorbit burns with target Cygnus for a destructive reentry back into the Earth’s atmosphere at 2:18 p.m. EDT, to plummet harmlessly into the Pacific Ocean.

Cygnus was developed by Orbital Sciences Corp. with seed money from NASA in a public-private partnership between NASA and Orbital Sciences under NASA’s COTS commercial transportation initiative.

SpaceX Corp. was also awarded a COTS contract to develop the Dragon cargo carrier so that NASA would have a dual capability to stock up the station.

COTS was aimed at fostering the development of America’s commercial space industry to deliver critical and essential supplies to the ISS following the retirement of the Space Shuttle program.

“Congratulations to the teams at Orbital Sciences and NASA who worked hard to make this demonstration mission to the International Space Station an overwhelming success,” NASA Administrator Charles Bolden said in a statement.

“We are delighted to now have two American companies able to resupply the station. U.S. innovation and inspiration have once again shown their great strength in the design and operation of a new generation of vehicles to carry cargo to our laboratory in space. Orbital’s success today is helping make NASA’s future exploration to farther destinations possible.”

America completely lost its capability to send humans and cargo to the ISS when NASA’s space shuttles were forcibly retired in 2011. Orbital Sciences and SpaceX were awarded NASA contracts worth over $3 Billion to restore the unmanned cargo resupply capability over 20 flights totally.

Cygnus was launched to orbit on its inaugural flight on Sept. 18 atop Orbital’s commercial Antares rocket from NASA’s Wallops Flight Facility on the Eastern shore of Virginia.

The initially planned Sept. 22 berthing of the spacecraft at a port on the Earth facing Harmony node was delayed a week to Sept. 29 due to an easily fixed communications glitch. It was no worse for the wear and performed admirably.

“Antares next flight is scheduled for mid December,” according to Frank Culbertson, former astronaut and now Orbital’s executive Vice President responsible for the Antares and Cygnus programs.

Skeleton Crew gets LADEE in Orbit, Checked Out and Fires Revolutionary Laser During Gov’t Shutdown

NASA’s new LADEE spacecraft successfully entered lunar orbit, is operating beautifully and has begun shooting its radical laser communications experiment despite having to accomplish a series of absolutely critical do-or-die orbital insertion engine firings with a “skeleton crew ” – all this amidst the NASA and US government shutdown, NASA Ames Research Center Director Pete Worden told Universe Today in a LADEE mission exclusive.

During the two and a half week long NASA shutdown, engineers had to fire LADEE’s maneuvering thrusters three times over six days – first to brake into elliptical orbit about the Moon and then lower it significantly and safely into a circular commissioning orbit.

“All burns went super well,” Ames Center Director Worden told me exclusivly. And he is extremely proud of the entire team of “dedicated” professional men and women who made it possible during the shutdown.

“It says a lot about our people’s dedication and capability when a skeleton crew can get a new spacecraft into lunar orbit and fully commissioned in the face of a shutdown!” Worden said to Universe Today.

“I’m really happy that everyone’s back.”

After achieving orbit, a pair of additional engine burns reduced LADEE’s altitude and period into its initial commissioning orbit and teams began the month long activation and instrument checkout phase.

“We are at the commissioning orbit of 250 km,” said Worden.

And to top all that off, LADEE’s quartet of science instruments are checked out and the ground – breaking laser communications experiment that will bring about a quantum leap in transmitting space science data has already begun its work!

“All instruments are fully checked out with covers deployed.”

“We’ve begun the Lunar Laser Communications Demonstration (LLCD) tests and its working very well,” Worden explained.

And that’s the whole point of the LADEE mission in the first place.

97% of NASA’s employees were furloughed during the utterly chaotic and wasteful partial shutdown of the US government that lasted from Oct. 1 to Oct. 17 and also temporarily threatened the upcoming launch of NASA’s next mission to Mars – the MAVEN orbiter.

However, orbital mechanics follows the natural laws of the Universe, continues unabated and waits for no one in Washington, D.C.

NASA’s Jupiter-bound Juno orbiter also flew by Earth amidst the DC shutdown showdown on Oct. 9 for a similarly critical do-or-die gravity assisted speed boost and trajectory targeting maneuver.

The stakes were extremely high for NASA’s Lunar Atmosphere and Dust Environment Explorer (LADEE) mission because the spacecraft was on course for the Moon and absolutely had to ignite its main engine on the Sunday morning of Oct. 6.

There were no second chances. If anything failed, LADEE would simply sail past the Moon with no hope of returning later.

So, mission controllers at NASA Ames commanded LADEE to ignite its main engine and enter lunar orbit on Oct. 6 following the spectacular Sept. 6 night launch from NASA’s Wallops Island spaceport in Virginia.

The approximately four minute long burn know as Lunar Orbit Insertion burn 1 (LOI-1) began with LADEE’s arrival at the Moon following three and a half long looping orbits of the Earth.

LOI-1 changed the spacecrafts velocity by 329.8 meters/sec so that the couch sized probe could be captured by the Moon’s gravity and be placed into a 24 hour polar elliptical orbit.

The LOI-2 maneuver on Oct. 9 put LADEE into a 4-hour elliptic lunar orbit. The third and final LOI-3 burn occurred on Oct. 12, and put the spacecraft into the 2-hour commissioning orbit (roughly 235 Km x 250 Km), according to a NASA statement.

The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.

“LADEE is the first NASA mission with a dedicated laser communications experiment,” said Don Cornwell, mission manager for the Lunar Laser Communications Demonstration (LLCD), NASA’s Goddard Space Flight Center, Greenbelt, Md, during an interview with Universe Today at the LADEE launch.

“With the LLCD experiment, we’ll use laser communications to demonstrate at least six times more data rate from the moon than what we can do with a radio system with half the weight and 25 percent less power,” said Cornwell.

This new ability could one day allow for 3-D High Definition video transmissions in deep space to become routine. Credit: NASA

The LLCD will be operated for about 30 days during the time of the commissioning orbit period.

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 $280 million probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.

“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Worden told Universe Today. “It will study the pristine moon to study significant questions.”

“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”
