Since SpaceX has a launch scheduled at the end of February, and SpaceX is generally late in their launches, how much can the SpaceX slip before running up against this March 13 scheduled launch?

If SpaceX slips, which launch has priority, or does this launch have to be postponed to give SpaceX the range?

NASA Media Accreditation Now Open for Magnetospheric Multiscale Mission

NASA’s Kennedy Space Center in Florida has opened accreditation for news media to attend the launch of the Magnetospheric Multiscale (MMS) mission. Launch will be aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station (CCAFS) March 12, 2015. The 30-minute launch window opens at 10:44 p.m. EDT.

MMS is an unprecedented NASA mission to study magnetic reconnection, a fundamental process that occurs throughout the universe. Unlike prior missions which have observed the evidence of magnetic reconnection events, the MMS mission will have sufficient resolution to measure characteristics of ongoing reconnection events as they occur. It has the primary task of collecting data to understand the mystery of how magnetic fields around Earth connect and disconnect, explosively converting magnetic energy into particle energy via a process known as magnetic reconnection.  MMS consists of four identical observatories that will provide the first three-dimensional view of magnetic reconnection. The four MMS observatories will fly through reconnection regions in a tight formation in well under a second, so key sensors on each spacecraft are designed to measure the space environment at rates faster than any previous mission.

The mission observes reconnection directly in Earth’s protective magnetic space environment known as the magnetosphere. By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere as well, such as in the atmosphere of the Sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.

For U.S. media, the deadline to apply for accreditation to cover launch activities on Kennedy Space Center and Cape Canaveral Air Force Station is noon on Thursday, March 5.

International media without U.S. citizenship may request access to cover launch and associated prelaunch activities from the Kennedy Space Center only. The deadline to apply for credentials is 4:30 p.m. EST on Feb. 25. International journalists are required to submit a scanned copy of their "I" visa and passport. Green card holders must submit a scanned copy of their card. Scanned documents must be sent to jennifer.p.horner@nasa.gov for the credential request to be processed.

All media representatives must present two forms of unexpired, government identification to enter Kennedy. One form must be a photo ID, such as a passport or driver's license.

All media accreditation requests need to be submitted online at:

https://media.ksc.nasa.gov

Questions about accreditation should be addressed to Jennifer Horner at jennifer.p.horner@nasa.gov, 321-867-6598 or 321-867-2468.

NASA Offers News Media Access to MMS Spacecraft Feb. 18

The Magnetospheric Multiscale (MMS) observatories will be the focus of a media opportunity at 9 a.m. EST Wednesday, Feb. 18, at the Astrotech Space Operations facility in Titusville, Florida. MMS is a NASA mission led by the Goddard Space Flight Center in Greenbelt, Maryland. The instrument payload science team consists of researchers from a number of institutions and is led by the Southwest Research Institute in San Antonio, Texas.  MMS will be launched on a United Launch Alliance Atlas V rocket managed by Kennedy Space Center’s Launch Services Program. Liftoff is targeted for March 12, 2015, at 10:44 p.m. EDT from Space Launch Complex 41 on Cape Canaveral Air Force Station.

MMS is an unprecedented NASA mission to study magnetic reconnection, a fundamental process that occurs throughout the universe. Unlike prior missions which have observed the evidence of magnetic reconnection events, the MMS mission will have sufficient resolution to measure characteristics of ongoing reconnection events as they occur.

MMS consists of four identical observatories that will provide the first three-dimensional view of magnetic reconnection. Because the four MMS observatories will fly through reconnection regions in a tight formation in well under a second, key sensors on each spacecraft are designed to measure the space environment at rates faster than any previous mission

The mission observes reconnection directly in Earth’s protective magnetic space environment known as the magnetosphere. By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere as well, such as in the atmosphere of the Sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.

Spokespersons from NASA's Goddard Space Flight Center will be available for questions and interviews.

Full clean-room attire must be worn and will be furnished. Journalists should not wear perfume, cologne or makeup. Long pants and closed-toe shoes must be worn. No shorts or skirts will be permitted. Because MMS is magnetically sensitive, magnets or devices containing magnets may not be brought in.  All equipment will be scanned for magnetic potential prior to entry. Camera equipment identified for cleaning will be cleaned by contamination control specialists before being taken into the high bay facility. The necessary alcohol wipes will be provided. Non-essential equipment such as suede, leather or vinyl camera bags or other carrying cases must be left outside the clean room.  Clean-room paper and non-retractable ballpoint pens will be provided.  No notebook paper, pencils or retractable pens can be permitted. No food, tobacco, chewing gum, lighters, matches or pocket knives will be allowed.

All camera equipment must be self-contained and no portable lights can be allowed. Flash photography will not be permitted; however, the facility has adequate metal halide lighting for pictures. Wireless microphones can be permitted inside the high bay if foam covers are removed; however cell phones inside the clean room are not allowed.

On Feb. 18, U.S. news media representatives may proceed directly to Astrotech, which is located in the Spaceport Florida Industrial Park, 1515 Chaffee Drive, Titusville. Access will be available starting at 8:45 a.m., and the event will begin at 9 a.m.

Only news media who are United States citizens may attend this event.  A government-issued photo identification, such as a driver's license or permanently issued NASA news media accreditation badge from Kennedy, will be acceptable. In addition, proof of U.S. citizenship also is required, such as a passport or birth certificate.

NASA’s Goddard Space Flight Center in Greenbelt, Maryland, built MMS.

Media representatives should call Kennedy's media update phone line at 321-867-2525 on Tuesday evening, Feb. 17, to confirm the event is on schedule.

Centaur Connection

Thursday, February 12, 2015 - 10:59

Engineers are lifting the Centaur upper stage into place today atop the United Launch Alliance Atlas V that will carry the MMS spacecraft into orbit. Working at Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida, the crews are using the cranes and fixtures inside the Vertical Integration Facility to perform today's stacking as preparations continue on pace for a March 12 launch of the mission. Several miles away at the Astrotech payload processing facility near NASA's Kennedy Space Center, the lower stack of two MMS spacecraft are being connected to the payload adapter for the Atlas V. MMS is comprised of four individual spacecraft with a total of 32 GPS antennas. Engineers have cleaned and inspected those antennas as well as all the instruments on the four spacecraft ahead of the stacking of all four together in their launch configuration scheduled for Feb. 16.

Frustrating to figure out this mission without a real press kit yet, but here are some details from: 
http://www.nasa.gov/mission_pages/mms/news/faqs.html#.VOC5EyyI4po

"At launch, with a full load of propellant, each observatory weighs approximately 2,998 pounds (1360 kg). This is slightly lighter than a 2012 Toyota Prius."

Each satellite is "4 feet tall and 12 feet wide. When stacked all together on the launch vehicle, the complete stack of four MMS observatories is over 16 feet tall. In space, with axial booms and wire booms extended, each observatory grows to be about 94 feet tall and 369 feet wide;"

The orbits:  "MMS will have two different orbits around Earth for two different mission phases. The first phase of the mission has an orbit that comes to 1,600 miles (2,550 km) altitude at its closest approach to Earth and at its farthest, extends out to 43,500 miles (70080 km). For the second mission phase, the closest approach remains the same, but the orbit will now extend out to 95,000 miles (152,900 km) at its farthest away from Earth – this is about 41% of the distance to the moon."

When these things deploy all of their booms, they will take up a lot of "space" as they spin, carving out a 112.5 meter wide circle.

The four satellites are supposed to fly in formation.

My understanding is that the inclination will be near equatorial.  I'm wondering if this will be a three-burn Centaur mission.

I assume so, given:
According to Gunter's Space Page, this launch will use the 4L payload fairing--4 meters in diameter, and 11.2 meters inner height.
http://space.skyrocket.de/doc_lau/atlas-5.htm (http://space.skyrocket.de/doc_lau/atlas-5.htm)

And, according to one of the attached images in Ed Kyle's post, the 4-satellite stack height is 5.933 meters.

 - Ed Kyle
If it's a three burn mission, it might be a really long one, assuming the normal sequence:  (1) get to parking orbit, (2) after arriving at equator, burn to hit apogee, (3) at apogee, raise perigee and reduce inclination.

But since even the initial apogee is higher than GTO, it takes longer to get there.  Back of the envelope says 12 hours between burns (2) and (3), as opposed to the 6 hours of dropping a satellite off in GEO.

Or maybe the Centaur does the usual, and the satellite does the rest.  I have no idea....

I'm sure you're right about the naming. I honestly haven't followed them since launch  :-[

I just remember them being stacked on top of each other and having multiple separations, similar to MMS (and maybe the Boeing 702SP??)

One note from the booklet:  The satellite releases will take place near the completion of the first orbit, as they traverse near and over the continental USA.  (However, tracking and data relay of spacecraft(s) separations will be via TDRSS?)

NASA | MMS Mission Overview

Published on Feb 19, 2015
Senior Project Scientist Tom Moore outlines the three instrument suites onboard the four MMS spacecraft.

On March 12, 2015, NASA plans to launch the Magnetospheric Multiscale, or MMS, mission. MMS consists of four identical spacecraft that will orbit around Earth through the dynamic magnetic system surrounding our planet to study a little-understood phenomenon called magnetic reconnection.

Watch NASA's new movie to learn more about MMS and the phenomenon of magnetic reconnection, which occurs near Earth, on the sun, in other stars and in the vicinity of black holes and neutron stars.

The Magnetiospheric Multiscale, or MMS, mission will provide unprecedented detail on a phenomenon called magnetic reconnection, which happens throughout the universe and can accelerate particles up to nearly the speed of light.

NASA will hold a media briefing at 1 p.m. EST Wednesday, Feb. 25, to discuss an upcoming mission to study magnetic reconnection around Earth, a fundamental process throughout the universe where magnetic fields connect and disconnect explosively releasing energy.

The briefing, held at NASA Headquarters, 300 E St. SW in Washington, will be broadcast live on NASA Television and streamed on the agency's website.

Called the Magnetospheric Multiscale (MMS) mission, the project will help scientists understand the process of magnetic reconnection, which can accelerate particles up to nearly the speed of light.  By studying reconnection near Earth, MMS will help scientists understand reconnection in the atmosphere of the sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.

The mission consists of four identical spacecraft that will provide the first three-dimensional view of magnetic reconnection. Launch is scheduled for 10:44 p.m. March 12, from Cape Canaveral Air Force Station in Florida.

The briefing participants are:

•Jeff Newmark, interim director, Heliophysics Division, NASA Headquarters in Washington
•Jim Burch, principal investigator, MMS Instrument Suite, Southwest Research Institute, San Antonio
•Craig Tooley, MMS Project Manager, NASA’s Goddard Space Flight Center in Greenbelt, Maryland
•Paul Cassak, associate professor, West Virginia University, Morgantown     

Media who want to participate by phone must send an email providing their name, affiliation and telephone number to dwayne.c.brown@nasa.gov by noon Wednesday.

Media and the public also may ask questions during the briefing on Twitter using the hashtag #askNASA.

Craig Tooley speaks to the launch, followed by deployment of the various booms and the quartet formation flying, using video.

Paul Cassak uses another CGI video to demonstrate magnetic field reconnection.  Solar field lines break and reconnect when encountering the Earth's magnetosphere on the sunward side of Earth's field.  Field lines break and reconnect in the Earth's magnetotail trailing away from the Sun.

Previous spatial resolution 600 km separation (this was ESA's Cluster?).  MMS spatial resolution is 10 km (with separation maintained within 100 m).

Time resolution is 100x better than any previous mission's.

Q&A
One question about the length of the mission, but confusing satellites with "shuttles."

Another question asking about MMS connection to recently-launched SMAP (there really isn't).

Question about how the formation of 4 MMS craft will be maintained--by GPS measurements, even though the MMS orbits are (mostly? all the time?) above GPS satellite altitude.  They will get enough signal from GPS satellite side-lobe transmission.

MMS nominal mission?--2 years.  Extended mission could be possible.  Also questioning the radiation environment MMS will be orbiting in.

Question about other planets with magnetic fields--Mercury, Jupiter, and Saturn mentioned in reply.

Another question--mention given to Cluster and THEMIS.

Instrument measurements are not necessarily tied to the spin rate of MMS craft.  They will be spinning slower than (most? all?) previous magnetic measurement satellites.

Question and answer about using Earth's magnetic field to understand black holes' magnetic fields.

What about using MMS data to understand space weather?  Data will be use to improve modeling of space weather.  These new observations are expected to prove or disprove current theories, because magnetic reconnection is currently understood relatively poorly.  An analogy is used--sea-faring drove the betterment of weather forecasting; thus space-faring is driving the improvement of space weather forecasting.

There are the brief closing statements, and it's over!

MMS media briefing:

NASA mission’s magnetic personality

Published on Feb 25, 2015
During a Feb. 25 briefing at NASA headquarters, details were discussed about the upcoming Magnetospheric Multiscale (MMS) mission, scheduled for launch March 12 from Cape Canaveral Florida. MMS will study a phenomenon called magnetic reconnection – a fundamental process during which magnetic fields around Earth connect and disconnect, releasing explosive energy. Magnetic reconnection also occurs throughout the universe and can accelerate particles up to nearly the speed of light.

NASA Spacecraft Prepares for March 12 Launch to Study Earth’s Dynamic Magnetic Space Environment

Final preparations are underway for the launch of NASA’s quartet of Magnetospheric Multiscale (MMS) spacecraft, which constitute the first space mission dedicated to the study of magnetic reconnection. This fundamental process occurs throughout the universe where magnetic fields connect and disconnect with an explosive release of energy.

“Magnetic reconnection is one of the most important drivers of space weather events,” said Jeff Newmark, interim director of the Heliophysics Division at NASA Headquarters in Washington. “Eruptive solar flares, coronal mass ejections, and geomagnetic storms all involve the release, through reconnection, of energy stored in magnetic fields. Space weather events can affect modern technological systems such as communications networks, GPS navigation, and electrical power grids.”

The launch of MMS, on a United Launch Alliance Atlas V rocket, will be managed by the Launch Services Program at NASA’s Kennedy Space Center in Florida. Liftoff is targeted for 10:44 p.m. EDT Thursday March 12 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida.

The spacecraft will begin science operations in September. Unlike previous missions to observe the evidence of magnetic reconnection events, MMS will have sufficient resolution to measure the characteristics of ongoing reconnection events as they occur.

The mission consists of four identical space observatories that will provide the first three-dimensional view of magnetic reconnection. Because the observatories will fly through reconnection regions in a tight formation, in less than a second, key sensors on each spacecraft are designed to measure the space environment at rates faster than any previous mission.

“MMS engineers have completed final observatory closeout procedures and checks and are awaiting transport to the launch pad tomorrow for integration with the Atlas rocket,” said Craig Tooley, MMS project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The team is in high spirits and ready to get these technological marvels in space.”

The mission observes reconnection directly in Earth’s protective magnetic space environment known as the magnetosphere. By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere, such as the atmosphere of the sun, the vicinity of black holes and neutron stars, and the boundary between our solar system and interstellar space.

“This is the perfect time for this mission,” said Jim Burch, principal investigator of the MMS instrument suite science team at Southwest Research Institute (SwRI) in San Antonio, Texas. “MMS is a crucial next step in advancing the science of magnetic reconnection. Studying magnetic reconnection near Earth will unlock the ability to understand how this process works throughout the entire universe.”

MMS is led by Goddard, which also built, integrated and tested the four spacecraft. The MMS Instrument Suite Science Team is led by SwRI. The spacecraft are controlled and operated from the MMS Mission Operations Center at Goddard. Science operations planning and instrument command sequence development are performed at the MMS Science Operations Center at the University of Colorado’s Laboratory for Atmospheric and Space Physics in Boulder.

MMS Rollout Now Planned for Friday

Wednesday, February 25, 2015 - 15:01

The rollout of NASA's MMS spacecraft from the Astrotech payload processing facility to Space Launch Complex 41 has been postponed 24 hours due to the weather forecast for tonight. It is rescheduled for the overnight hours of Friday morning pending the outcome of a weather briefing on Thursday afternoon. This will not affect the March 12 launch date. Meanwhile, MMS is being placed on the payload transporter today.

Anyone have a guess where/when blow down and venting of the Centaur will occur?

Since this is a night launch, there is a good chance people from the southern US will be able to see it. If it occurs late enough, those of us further north will be able to see it. These events are quite noticeable to the unaided eye looking like a large slow moving ball of gas.

Having watched two NOSS Centaur blow downs from the light polluted Boston area, I can tell you, they are well worth watching. I highly recommend people in the southern US try to spot it. It is a nice treat.

Blowdown should start around T+2h 10m, but I'm not sure where the stage will be - probably somewhere south of Florida or southeast in the Caribbean. It's ~25m after the last S/C sep, which takes place over the Gulf of Mexico. My data source is a few months old, so there may be some refinements to that timeline.

Thanks for posting the article, Foltster!

Using such weak signal is impressive (to me) at GSO.  Geostationary (geosynchronous and circular) orbit has a radius (not altitude) of approximately 7 Earth radii.

MMS will spend most of any given orbit beyond that altitude, slowly sweeping along their highly elliptical orbits near apogee.

Phase 1 of the MMS mission will use an orbit of 1.2 RE X 12 RE X 28 deg--this is to measure magnetic reconnection on the dayside of the magnetopause.

Phase 2 will culminate in an orbit of 1.2 RE X 25 RE X 28 deg--to measure magnetic reconnection in the magnetotail.

MMS Cleared to Proceed Toward Launch

Friday, March 6, 2015 - 12:38

At the conclusion of a Flight Readiness Review on Friday, March 6, NASA and United Launch Alliance (ULA) managers gave a "go" to continue preparations leading to the planned liftoff of the Magnetospheric Multiscale (MMS) spacecraft atop a ULA Atlas V rocket at 10:44 p.m. EDT on Thursday, March 12. The Mission Dress Rehearsal, during which MMS and the Atlas will be powered up, is scheduled for Monday, March 9. The final management review before flight, the Launch Readiness Review (LRR), will be conducted on Tuesday, March 10. Following the LRR, NASA Television will air the MMS Prelaunch News Conference at 1 p.m. EDT.

MMS will study magnetic reconnection, a fundamental process that occurs throughout the universe when magnetic fields connect and disconnect explosively, releasing energy and accelerating particles up to nearly the speed of light. Unlike previous missions that have observed only evidence of magnetic reconnection events, MMS has sufficient resolution to observe and measure reconnection events as they occur.

Atlas 5 and other Atlas launches have occurred many times on the 13th of a month, and none have failed in recent memory.  We have to go way back to 1978 to see an Atlas launch (an Atlas F) take place on a Friday the 13th, and it was a roaring success (a Tiros N).  Another way to look at this is that all of the Atlas family failures that have occurred have happened on a date that was not a 13th!

FYI, Delta 194, a Delta 2, successfully orbited Palapa B2R on April, Friday the 13th, 1990.  This satellite had been recovered by Shuttle after an AKM failure during a previous Shuttle mission that was not launched on a Friday the 13th (no Shuttles ever launched on a Friday the 13th)!

Looking back through the logs, it seems apparent, or at least likely, that managers have steered clear of Friday 13th launch dates over the years.  That needs to end.

re: this launch's date and Triskaidekaphobia

The launch time falls on Friday the 13th in UTC.  CCAFS is in the Eastern Time Zone--the launch time falls on the evening of the 12th in EST (UTC - 5 hours = EST).

I agree with Ed Kyle: if managers are avoiding launching on Friday the 13th due to superstition, then the superstition needs to stop, please.

My 2 cents,

ULA:

Everything is progressing toward NASA’s MMS launch. The mission is set to liftoff on a ULA Atlas V rocket on Thursday, March 12 from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. The 30-minute launch window opens at 10:44 p.m. EDT. Today’s L-4 forecast shows an 70 percent chance of favorable weather conditions for launch. I have included the mission art.

Re:  "...then this superstition needs to stop"

What superstition??  The one you created?  I assure you the people scheduling launches do not take this into consideration.

Go back and look at all scheduled launch dates (not when actually flown) a month or more out for ULA launches.  Tell me what day of the week the launch is scheduled for, at the site.

There might be a couple, like interplanetary, that are different, but it sure looks like a trend to me.

Mission Dress Rehearsal Today for MMS

Monday, March 9, 2015 - 11:23

Launch week for NASA's MMS mission began today with a dress rehearsal for the teams that will take part in Thursday night's launch. The teams, including NASA's Kennedy and Goddard centers, United Launch Alliance and Southwest Research Institute, are replicating all countdown activities for the Atlas V rocket and the four MMS observatories. The weather forecast for Thursday calls for 70 percent chance of acceptable conditions during the 30-minute launch window. The concern is for cloud constraints. Liftoff time is scheduled for 10:44 p.m. EDT on Thursday.

Atlas V MMS Mission Profile

Published on Mar 9, 2015
The Magnetospheric Multiscale, or MMS, mission studies the mystery of how magnetic fields around Earth connect and disconnect, explosively releasing energy via a process known as magnetic reconnection. MMS consists of four identical spacecraft that work together to provide the first three-dimensional view of this fundamental process, which occurs throughout the universe.

Forecast Remains 70 percent 'Go'

Tuesday, March 10, 2015 - 10:16

Two days from launch, forecasters from the U.S. Air Force 45th Weather Squadron continue to predict a 70 percent chance of favorable weather for the liftoff of NASA’s Magnetospheric Multiscale (MMS) spacecraft atop a United Launch Alliance Atlas V rocket during a 30-minute launch window that opens at 10:44 p.m. EDT on Thursday, March 12. The final management review before flight, the Launch Readiness Review (LRR), will be conducted this morning. Following the LRR, NASA Television will air the MMS Prelaunch News Conference at 1 p.m. EDT.

Not true. Around the time of the MMS separations they will be between 5000 and 6000 km, altitude, and will be visible from Canada all the way down to Peru. Visibility will improve even further at the time of the fuel dump when the objects are at even higher altitudes.

From the ground track in ULA's mission book ( http://www.ulalaunch.com/uploads/docs/Mission_Booklets/AV/av_mms_mob.pdf ) I would guess blowdown would be somewhere in the green circle. So, depending where you are, I would be looking high in the sky in that direction.

As a fun exercise Boston is ~2500km north of Cuba, and these events should be happening at 5000 km (ignoring the earths curvature) that is what, about 60ish degrees above the horizon, hand wave in the earths curvature and you are talking what, 45 degrees?

Atlas V Rolled to Launch Pad for MMS

Published on Mar 12, 2015
The United Launch Alliance Atlas V rocket is rolled from Vertical Integration Facility to the pad at Launch Complex 41. With four identical Magnetospheric Multiscale, or MMS, spacecraft, this is an unprecedented NASA mission to study magnetic reconnection. Scientists believe MMS will provide insights into the fundamental process that occurs throughout the universe.

Kim, thank's for the blow down time, based on the seesat estimates it puts it just entering earths shadow. I'll set an alarm then try to sneak past the gator and take a look tonight. I wonder if the cloud will hold together long enough to see it emerge from earths shadow.

NASA Education (the one I get on my cable system) is running NASA Edge (trying to present rocket science at a 2nd grade reading level) as their launch coverage, so we have a guy "dramatizing" the clean room environment by sitting at their viewing deck in a plastic bubble.  At least it's not as bad as the cartoon TV talk show they run, where the real guests are portrayed as animated cartoon characters and interviewed by 8-year-olds, also done as cartoons.

They just tried to compare the cold of the cryo propellants vs. the heat of the rocket engine as "The Human Torch vs. Mr. Freeze."  Complete with comic book panels.

And ooops -- somehow I had the T-0 time as 9:15pm, I was off by 30 minutes.  Post edited.

As the vehicle passed over Vandenberg AFB, I went outside just as a lark and, sure enough there was some sort of visible venting event just as it passed the zenith around 9:18 PST!  A bright pinpoint of light expanded quickly to the size of a misty full moon then expanded into a diffuse cloud that passed right in front of a brightly shining Jupiter before dissipating completely after about 3 minutes. Great show and the first time I've seen a Centaur doing its thing.

As the vehicle passed over Vandenberg AFB, I went outside just as a lark and, sure enough there was some sort of visible venting event just as it passed the zenith around 9:18 PST!  A bright pinpoint of light expanded quickly to the size of a misty full moon then expanded into a diffuse cloud that passed right in front of a brightly shining Jupiter before dissipating completely after about 3 minutes. Great show and the first time I've seen a Centaur doing its thing.



Ah darn, wish I could have gone out and watched that myself.

NASA Spacecraft in Earth’s Orbit, Preparing to Study Magnetic Reconnection

   
Following a successful launch at 10:44 p.m. EDT Thursday, NASA’s four Magnetospheric Multiscale (MMS) spacecraft are positioned in Earth’s orbit to begin the first space mission dedicated to the study of a phenomenon called magnetic reconnection. This process is thought to be the catalyst for some of the most powerful explosions in our solar system.

The spacecraft, positioned one on top of the other on a United Launch Alliance Atlas V 421 rocket, launched from Cape Canaveral Air Force Station, Florida. After reaching orbit, each spacecraft deployed from the rocket’s upper stage sequentially, in five-minute increments, beginning at 12:16 a.m. Friday, with the last separation occurring at 12:31 a.m. NASA scientists and engineers were able to confirm the health of all separated spacecraft at 12:40 a.m.

"I am speaking for the entire MMS team when I say we’re thrilled to see all four of our spacecraft have deployed and data indicates we have a healthy fleet,” said Craig Tooley, project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
 
Over the next several weeks, NASA scientists and engineers will deploy booms and antennas on the spacecraft, and test all instruments. The observatories will later be placed into a pyramid formation in preparation for science observations, which are expected to begin in early September.

“After a decade of planning and engineering, the science team is ready to go to work,” said Jim Burch, principal investigator for the MMS instrument suite science team at the Southwest Research Institute in San Antonio (SwRI). “We’ve never had this type of opportunity to study this fundamental process in such detail.”

The mission will provide the first three-dimensional views of reconnection occurring in Earth's protective magnetic space environment, the magnetosphere. Magnetic reconnection occurs when magnetic fields connect, disconnect, and reconfigure explosively, releasing bursts of energy that can reach the order of billions of megatons of trinitrotoluene (commonly known as TNT). These explosions can send particles surging through space near the speed of light.

Scientists expect the mission will not only help them better understand magnetic reconnection, but also will provide insight into these powerful events, which can disrupt modern technological systems such as communications networks, GPS navigation, and electrical power grids.

By studying reconnection in this local, natural laboratory, scientists can understand the process elsewhere, such as in the atmosphere of the sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system's heliosphere and interstellar space.
 
The spacecraft will fly in a tight formation through regions of reconnection activity. Using sensors designed to measure the space environment at rates100 times faster than any previous mission.

“MMS is a crucial next step in advancing the science of magnetic reconnection – and no mission has ever observed this fundamental process with such detail,” said Jeff Newmark, interim director for NASA’s Heliophysics Division at the agency’s Headquarters in Washington. “The depth and detail of our knowledge is going to grow by leaps and bounds, in ways that no one can yet predict.”

MMS is the fourth mission in the NASA Solar Terrestrial Probes Program. Goddard built, integrated and tested the four MMS spacecraft and is responsible for overall mission management and operations. The principal investigator for the MMS instrument suite science team is based at the SwRI. Science operations planning and instrument commanding are performed at the MMS Science Operations Center at the University of Colorado Boulder’s Laboratory for Atmospheric and Space Physics.

I truly expected nothing, but the NASA-TV coverage showed that the ground track was going to come right overhead so I went outside. I was looking more southerly when the flash and outgassing happened nearly directly above. I wish I'd brought a camera out, it was a very visible event and would have photographed well. Watching the cloud diffuse and surround Jupiter was a cool bonus.

From the Spaceweather site, someone did get a shot of what I saw when the Centaur passed overhead California. This venting happened about right around the time of first MMS spacecraft deployment.


The bright "star" to the left is Jupiter and the cloud passed directly in front of it before dissipating.

If the statement in bold is correct, you're seeing the RCS plume from the spin up.  Centaur does not perform other venting during spacecraft separation events.

Late to the game, but I too went outside at L+2h7m and watched from Jupiter SE to the horizon and didn't see any pluming.  Nice evening though, and the most important thing is how successful the launch and deployment were.  Congrats to all the teams, and to NASA TV for the great coverage.  Wow!

Orbital ATK Supports Exploration of Earth's Magnetosphere 

Orbital ATK Flight, Defense and Space Technologies Help Launch NASA MMS Satellites

(Dulles, Virginia 13 March 2015) – Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, provided critical hardware for the United Launch Alliance (ULA) Atlas V vehicle that launched four, first-of-their-kind NASA satellites last night from Cape Canaveral Air Force Station, Florida.

NASA’s MMS (Magnetospheric Multiscale) is a Solar Terrestrial Probes program comprising four identically instrumented satellites that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes of space weather occurring in near-Earth space: magnetic reconnection, energetic particle acceleration and turbulence. These processes can interfere with GPS signals and radio communications and cause excess radiation, forcing airlines to divert their flight paths. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, designed and built the MMS satellites and will also be responsible for mission operations.

“Witnessing yet another successful launch of an Atlas V serves as a reminder of how much Orbital ATK values our partnerships with ULA and NASA,” said Ron Grabe, President of Orbital ATK’s Flight Systems Group. “Our highly engineered composite and control products play an important role in ensuring dependable access to space and affordable innovation for our customers.”

Orbital ATK produced the 10-foot diameter composite heat shield, which provides essential protection for the first stage of the launch vehicle. The assembly was fabricated using advanced fiber placement manufacturing techniques at the company’s Iuka, Mississippi, facility. This is the 53rd Atlas V launch using Orbital ATK-built composite structures. This flight also marked the 18th successful flight of the Orbital ATK retro motors. Eight of these solid motors supported separation of the spent first stage. The Atlas V retrorocket is built by Orbital ATK’s Defense Systems Group at its facility in Elkton, Maryland. The ULA Atlas V rocket flew in the 421 vehicle configuration.

For the NASA MMS satellites, Orbital ATK’s Space Systems Group built the observatory decks, spacecraft decks and bulkhead support panels at its Beltsville, Maryland, facility. The company delivered the aluminum honeycomb structural panels directly to NASA’s Goddard Space Flight Center.

Not sure if this was stated here on NSF. But that was exactly what I remembered from the 3rd X-37B launch in December 2012 (one can check all the threads here for confirmation).

Anyway it took some luck for the Atlas to do so - the DIV hit weather problems for the last 3 times and Atlas just got lucky that on those days they were able to fly before the end of the window.  ;)

Rippled Quasiperpendicular Shock Observed by the Magnetospheric Multiscale Spacecraft

Quote
Collisionless shock nonstationarity arising from microscale physics influences shock structure and particle acceleration mechanisms. Nonstationarity has been difficult to quantify due to the small spatial and temporal scales. We use the closely spaced (subgyroscale), high-time-resolution measurements from one rapid crossing of Earth’s quasiperpendicular bow shock by the Magnetospheric Multiscale (MMS) spacecraft to compare competing nonstationarity processes. Using MMS’s high-cadence kinetic plasma measurements, we show that the shock exhibits nonstationarity in the form of ripples.
