Skywatchers across Central Florida got an unusual view early Wednesday morning in conjunction with the Atlas V launch of the MUOS-4 satellite.
“That wasn’t thunder this AM, Florida: An absolutely stunning MUOS launch!” tweeted photographer Michael Seeley, who shared several images of the launch with Universe Today. Mike is a freelance photographer and works with Spaceflight Insider. You can see more of his imagery at his website.
The pre-dawn light combined with unusual atmospheric conditions produced stunning views both during and well after the launch. The skyshow was visible across a wide area.
“Folks as far south as Miami and up to Jacksonville to the north saw it,” Universe Today’s David Dickinson said. “I even heard kids waiting for the school bus on our street crying out in surprise!”
You can read more about the launch and the mission in our article from Ken Kremer, but see a stunning gallery of images of the unusual cloud formations following the launch below:

This picture of our home planet truly is EPIC – literally! The full-globe image was acquired with NASA’s Earth Polychromatic Imaging Camera (aka EPIC; see what they did there) on board NOAA’s DSCOVR spacecraft, positioned nearly a million miles (1.5 million km) away at L1.
L1 is one of five Lagrange points that exist in space where the gravitational pull between Earth and the Sun are sort of canceled out, allowing spacecraft to be “parked” there. (Learn more about Lagrange points here.) Launched aboard a SpaceX Falcon 9 on Feb. 11, 2015, the Deep Space Climate Observatory (DSCOVR) arrived at L1 on June 8 and, after a series of instrument checks, captured the image of Earth’s western hemisphere above on July 6.
The EPIC instrument has the capability to capture images in ten narrowband channels from infrared to ultraviolet; the true-color picture above was made from images acquired in red, green, and blue visible-light wavelengths.
More than just a pretty picture of our blue marble, this image will be used by the EPIC team to help calibrate the instrument to remove some of the blue atmospheric haze from subsequent images. Once the camera is fully set to begin operations daily images of our planet will be made available on a dedicated web site starting in September.

Designed to provide early warnings of potentially-disruptive geomagnetic storms resulting from solar outbursts, DSCOVR also carries Earth-observing instruments that will monitor ozone and aerosols in the atmosphere and measure the amount of energy received, reflected, and emitted by Earth – the planet’s “energy budget.”
But also, from its permanent location a million miles away, DSCOVR will be able to get some truly beautiful – er, EPIC – images of our world.

The skies, they are uh changin’… I remember reading in Astronomy magazine waaaay back in the late 1990s (in those days, news was disseminated in actual paper magazines) about a hot new constellation of satellites that were said to flare in a predictable fashion.
This is the Iridium satellite constellation, a series of 66 active satellites and six in-orbit and nine ground spares. The ‘Iridium’ name comes from the element with atomic number 77 of the same name (the original project envisioned 77 satellites in low Earth orbit), and the satellites serve users with global satellite phone coverage.

Over the years, Iridium satellite flares have become a common sight in the night sky… but that may change soon.
Known as Iridium-NEXT, the first launch is set for October of this year from Dombarovsky air base Russia atop a converted ICBM Dnepr rocket. The Dnepr can carry two satellites on each launch, and SpaceX has also recently agreed to deploy 70 satellites over the span of seven missions launching from Vandenberg Air Force Base in California later this year.
Both the initial Iridium satellites and Iridium NEXT are operated by Iridium Communications Incorporated. The original satellites were built by Motorola and Lockheed Martin, and the prime contract for Iridium NEXT construction went to Thales Alenia Space.
There are also several fascinating issues surrounding the history of the Iridium constellation, both past and present.
Originally fielded by Motorola in the 1990s, satellite phones were to be “the next big thing” until mobile phones took over. Conceived in the late 1980s, the concept of satellite phones was practically obsolete before the first Iridium satellite got off the ground. The high cost of satellite phone services assured they could never manage to compete with the explosive growth of the mobile phone industry, and satellite phones at best only found niche applications for remote operations worldwide. Iridium Communications declared bankruptcy in 1999, and the $6 billion US dollar project was bought by a group of private investors for only $35 million dollars.

The original Iridium constellation employed a unique system of Inter-Satellite Links, enabling them to directly route signals from satellite to satellite. Iridium NEXT will use an innovative L-band phased array antenna, allowing for larger bandwidth and faster data transmission. The Iridium NEXT constellation is planned to eventually contain 81 satellites including spares, and the system will be much more robust and reliable.
The Iridium NEXT constellation will also face some stiff competition, as Google, SpaceX and OneWeb are also looking to get into the business of satellite Internet and communications. This will also place hundreds of new satellites—not to mention the growing flock of CubeSats—into an already very crowded region of low Earth orbit. The Iridium 33 satellite collision with the defunct Kosmos 2251 satellite in 2009 highlighted the ongoing issues surrounding space debris.
The company applied for a plan to deorbit the original Iridium constellation starting in 2017 as soon as the new Iridium NEXT satellites are in place.
Now, I know what the question of the hour is, as it’s one that we get frequently from other satellite spotters and lovers of artificial things that flash in the sky:
Will the Iridium NEXT satellites flare in manner similar to their predecessors?
Unfortunately, the prospects aren’t good. Missing on Iridium NEXT are the three large refrigerator-sized antennae which are the source of those brilliant -8 magnitude flares. And sure, while these flares weren’t Iridium’s sole mission purpose, they were sure fun to watch!
An ‘Iridium classic…’ note the trio of reflective antennae on the lower bus. Image credit: Iridium Communications inc.
David Cubbage, Associate Director of NEXT Spacecraft Development and Satellite Production recently told Universe Today:
“It was very exciting when we first discovered that the Iridium Block 1 satellite vehicles (SVs) reflected the sunlight into a concentrated “flare” that could be viewed in the night sky. The unique design of the Block 1 SV, with three highly reflective Main Mission Antennas (MMA) deployed at an angle from the SV body, is what caused that to happen. For the Iridium NEXT constellation, the SVs will be built under a different design with a single MMA that faces the Earth — a design that requires fewer parts that do not need to be as reflective. As a result, it will not likely produce the spectacular flares of the Block 1 design.”
But don’t despair. Though the two decade ‘Age of the Iridium flare’ may be coming to an end, lots of other satellites, including the Hubble Space Telescope, MetOp-A and B, and the COSMO-SkyMed series of satellites can ‘slow flare’ on occasion. We recently saw something similar during a pass of the U.S. Air Force’s super-secret ATV-4 space plane currently carrying out its OTV-4 mission, suggesting that a large reflective solar panel may be currently deployed.

And though the path to commercial viability for satellite internet and communications is a tough one, we hope it does indeed take off soon… we personally love the idea of being able to stay connected from anywhere worldwide.
Be sure to catch those Iridium flares while you can… we’ll soon be telling future generations of amateur astronomers that we remember “back when…”

Situated on the south shore of New Jersey’s Shark River lies 37 acres of land known as Camp Evans. On April 1, 2015, I was privileged to attend the dedication ceremony celebrating Camp Evans’ becoming one of only 2532 locations in the United States designated as a National Historic Landmark.
In 1912, Gugliemlo Marconi and his company, the American Marconi Company, constructed the Belmar Receiving Station which became part of the wireless girdle of the earth.
In 1917, the site was acquired as part of the Navy’s World War I “Trans-Atlantic Communication System.”
In 1941, the Army Signal Corps purchased the property to construct a top-secret research facility, and it was renamed Evans Signal Laboratory which later became Camp Evans Signal Laboratory.
Following a visit in late October, 1953, Senator Joseph McCarthy described Camp Evans as a “house of spies.” Following an investigation that spanned 1953-1954, not one single employee was prosecuted.
But perhaps Camp Evans’ most interesting – and surprising – place in history begins with a small, informal research project taking place on a parcel of land in the Camp’s northeast corner. The ramifications of this project would ultimately give birth the to Space Age, lead to the development of the US Space Program, and start the Cold War.
Following the end of WWII, American scientists at Camp Evans continued their investigation into whether the earth’s ionosphere could be penetrated using radio waves – a feat that had been studied prior to the end of the War but had long been believed impossible. Project Diana, led by Lt. Col. John H. DeWitt, Jr., aimed to prove that it could indeed be penetrated. A group of radar scientists awaiting their discharge from the Army modified a radar antenna – including significantly boosting its output power – and placed it in the northeast corner of Camp Evans.

On the morning of January 10, 1946, with the dish pointed at the rising moon, a series of radar signals was broadcast. Exactly 2.5 seconds after each signal’s broadcast, its corresponding echo was detected. This was significant because 2.5 seconds is precisely the time required for light to travel the round trip distance between the earth and the moon. Project Diana – and her scientists – had successfully demonstrated that the ionosphere was, in fact, penetrable, and communication beyond our planet was possible. And thus was born the Space Age – as well as the field of Radar Astronomy.

As part of this effort, the original “Moonbounce” antenna was replaced with a 60-foot parabolic radio antenna dish which would serve as the project’s downlink Ground Communication Station.
60-Meter Parabolic Dish Being Constructed on Project Diana Site [photo: Frank Vosk; InfoAge website]On April 1, 1960, NASA successfully launched its TIROS I satellite and the “Silent Sentinel Radio Dish” at Camp Evans began receiving its data being sent down to earth.
TIROS I Satellite [photo: NASA; National Space Science Data Center]The resulting images were so astonishing and groundbreaking that the first photos received from TIROS I were immediately printed and flown to Washington where they were presented to President Eisenhower by NASA Administrator T. Keith Glennan.

[photo: wikimedia commons]The TIROS program would go on to be instrumental in meteorological applications not only because it provided the first accurate weather forecasts and hurricane tracking based on satellite information, but also because it began providing continuous coverage of the earth’s weather in 1962, and ultimately lead to the development of more sophisticated observational satellites. [1]
In addition to serving as the downlink Ground Communications Center for the TIROS I and TIROS II satellites, this same dish has also tracked:
Explorer 1, America’s first satellite, in January, 1958 (pre-dates the launch of TIROS I), and
Sadly, by the mid-1970s, the technology within the TIROS dish (officially named the TLM-18 Space Telemetry Antenna) had become obsolete, and it was retired. Camp Evans was decommissioned and closed in 1993 and its land was transferred to the National Park Service. But in 2012, Camp Evans was designated a National Historic Landmark, and thus began a new, revitalized era for this immensely significant site. In addition to the TIROS Dish and the InfoAge Science History Learning Center and Museum, Camp Evans is also home to:
The Military History Museum;
The Radio Technology Museum;
The National Broadcasters’ Hall of Fame.

DISH RESTORATION
In 2001, InfoAge stepped in and began preserving and restoring the mechanical systems of the TIROS dish. In 2006, a donation from Harris Corporation allowed the dish to be completely repainted and preserved.
Norman Jarosik, Senior Research Physicist at Princeton University and Daniel Marlow, PhD. and Evans Crawford 1911 Professor of Physics at Princeton, as well as countless volunteers from the University, InfoAge, Wall Township (NJ), and the Ocean-Monmouth Amateur Radio Club, Inc. (OMARC) have provided the engineering/scientific knowledge and sweat-equity required to refurbish and update the inoperative radio dish. The original vacuum-tube technology has been replaced with smaller electronic counterparts. Rusty equipment has been replaced. Seized/inoperative motors have been reconditioned and rebuilt. And system-level software controls have been added. The TIROS dish has been transformed into a truly modern, state-of-the-art Radio Astronomy Satellite Dish and Control Center.

Graziano]On January 19, 2015, scientists from Princeton University pointed the dish skyward toward the center of our galaxy and detected a clear peak at 1420.4 MHz, the well-known 21 cm emission line originating from the deepest recesses of the Milky Way – the dish was working!

FUTURE PLANS
After almost 15 years of restoration and nearly 40 years since it last listened to the sky, the TIROS dish is once again operational, is detecting radio signals from the universe, and is well on its way to be used for science education.
Work continues on renovating Building 9162, the original TIROS Control Building, to convert it into the InfoAge Visitor Center. Plans include a NASA-style control room with theater seating for 20-30 students, a full-scale model of the original TIROS I satellite, and other exhibits dedicated to the history of Project Diana, the TIROS program, and the scientific impact these projects have had on our daily lives.

The summer season means long days and short nights, as observers in the northern hemisphere must stay up later each evening waiting for darkness to fall. It also means that the best season to spot that orbital outpost of humanity—the International Space Station—is almost upon us. Get set for multiple passes a night for observers based in mid- to high- northern latitudes, starting this week.
This phenomenon is the result of the station’s steep 52 degree inclination orbit. This means that near either solstice, the ISS spends a span of several days in permanent illumination. Multiple sightings favor the southern hemisphere around the December solstice and the northern hemisphere right around the upcoming June solstice.
Here’s a rundown of the ‘ISS all night’ season for 2015. The Sun rises on the ISS after a brief three minute orbital night on May 30th, 2015 at 16:43 UT, and doesn’t set again until five days later on June 4th at 4:57 UT over the central US. The ISS full illumination season comes a bit early this year—a few weeks before the June 21st northward solstice—and the next prospect at the end of July sees the Sun angle juuust shy of actually creating a second summer season.

NASA engineers refer to this period as high solar beta angle season. For a satellite in low Earth orbit, the beta angle describes the angle between its orbital plane and the relative direction of the Sun. Beta angle governs the satellite’s length of time in darkness and daylight. In the shuttle era, the Space Shuttle could not approach the ISS during these ‘beta cutout’ times, and the station generally goes into ‘rotisserie mode,’ as the ISS is rotated and its solar panels feathered to create alternating regions of artificial darkness in an effort to combat the continuous heating.

Why the 52 degree inclination orbit for the station? This allows the ISS to be accessible from launch sites worldwide in the spirit of international cooperation exemplified by the ISS. The station can and has been reached by cargo and human crews launching from Cape Canaveral and the Kennedy Space Center in Florida, the Baikonur Cosmodrome, the Tanegashima space port in Japan, and Kourou space center in French Guiana.
Our friend @OzoneVibe on Twitter suggested to us a few years back that a one night marathon session of ISS sightings be known as a FISSION, which stands for Four/Five ISS sightings In One Night. The prospective latitudes to carry out this feat run from 45 to 55 degrees north, which corresponds with northern Europe, the United Kingdom, and the region just north and south of the U.S./Canadian border.

At 72.8 by 108.5 metres in size and orbiting the Earth once every 92 minutes at an average 400 kilometres in altitude, the ISS is the brightest object in low Earth orbit, and reaches magnitude -2 in brightness—not quite as bright as Venus at maximum brightness—on a good overhead pass. Depending on the approach angle, I can just make out a bit of detail when the ISS is near the zenith, looking like either a box, a close double star, or a tiny Star Wars TIE fighter through binoculars. Numerous apps and platforms exist to predict ISS passes based on location, though our favorite is still the venerable Heavens-Above. It’s strange to think, we were using Heavens-Above to chase Mir back in the late 1990s!
There’s another interesting challenge, which, to our knowledge, has never been captured as we near high beta angle season for the ISS: catching an ‘ISS wink out,’ or that brief sunset followed by sunrise a few minutes later on the same pass. It’s worth noting that the central United States may see just such an event during an early morning pass on June 4th… will you be the first to witness it?

Photographing the ISS is as easy as setting a DSLR on a tripod with a wide field of view lens, and doing a simple time exposure as it drifts by. Be sure to manually set the focus before the pass… Venus is currently well placed as a ‘mock ISS’ to get a fix on beforehand.
And amateur observers can even capture detail on the ISS, though this requires a camera running video coupled to a telescope. High precession tracking is desirable, though not mandatory: we’ve actually got descent results manually aiming a scope at the ISS with video running. The ISS appears in post production, occasionally skipping through the field of view.
Another unique method is to know when the ISS will transit the Sun, Moon or near a bright planet or star, aim your rig at the right spot, and let the station come to you. A good site to tailor alerts for such occurrences is CALSky.

After high beta angle season, missions to and from the ISS will resume. This includes the return of ISS crewmembers Shkaplerov, Christoforetti and Virts on June 7th, followed by a Soyuz launch with Kononeko, Yui, and Lindgren on July 24th. Also on tap is SpaceX’s Dragon capsule on CRS-7 launching on June 26th, the return to flight for Progress on July 3rd, and a HTV-5 launch for JAXA on August 17th. These can also provide interesting views for ground observers as well, as these spacecraft follow the ISS in its orbit on approach like tiny fainter ‘stars.’
A busy season indeed. Don’t miss a chance to see the ISS coming to a sky near you, and watch as humans work together aboard this orbiting science platform in space.
Screenshot of an Iridium satellite flare right next to Jupiter's location in the sky. From video by Thierry Legault.
Cue the “Space Invaders” sound effects! We’ve shared previously how astrophotographer Thierry Legault will travel anywhere to get a unique shot. He took this impressive but fun video of an Iridium 72 satellite flaring and passing in front of Jupiter, traveling to Oostende Beach at the North Sea in Belgium to capture this transit. He took both a wide angle view as well as the telescopic close-up view of Jupiter, and from the vantage point of Earth, it appears as though Jupiter gets blasted by the flare. In the zoomed-in view, even Jupiter’s moons are part of the scene.
You can almost hear the “pew-pew.”
Legault also shared a another recent video he shot of the Chinese Yaogan 6 satellite. “It is probably out of control, quickly tumbling with very bright and short flashes,” Legault said, and it has been tumbling for about a year. Yaogan 6 is a radar reconnaissance satellite launched by China in 2009. Legault said he did the tracking by hand with professional video tripod with a fluid head.

For the second time in less than three weeks, a major disaster struck the Russian space program when the launch of a Proton-M rocket ended in catastrophic failure about eight minutes after today’s (May 16) liftoff from the Baikonur Cosmodrome in Kazakhstan, resulting in the complete destruction of the Mexican communications satellite payload.
The Proton-M rocket initially lifted off successfully at 11:47 a.m. local time (1:47 a.m. EDT, 547 GMT) from the Baikonur Cosmodrome in Kazakhstan, but soon experienced an “emergency situation at 497 seconds into the flight,” according to a brief official statement released by Roscosmos, the Russian Federal Space Agency today, after the mishap.
The launch catastrophe was caused by a failure in the rockets Breeze-M third stage, says Roscosmos. It took place during a live broadcast from the agency’s website. A video shows the rocket disappearing into cloudy skies shortly after liftoff.
The failure comes just one week after the spinning, out-of-control Russian Progress 59cargo freighter bound for the ISS met its undesired early demise when it fell uncontrolled from orbit last Friday, May 8, following its botched April 28 launch on a Russian Soyuz-2.1A carrier rocket, also from Baikonur – as reported by Universe Today – here, here, and here.
The Proton-M carrier rocket was lofting the Mexsat 1 communications satellite, also known as Centenario, under a contract with the Mexican government.
“The failure happened on the 497th second of the flight, at an altitude of 161 kilometers [100 miles]. The third stage, the booster vehicle and the spacecraft almost completely burned up in the atmosphere. As of now there are no reports of debris reaching the ground,” the agency said in a statement.

The Breeze-M third stage was to loft Mexsat 1 to its destination in geostationary orbit over 22,000 miles above Earth at 113 degrees west longitude.
The 58.2 m (191 ft) tall Proton rocket is built and operated by Khrunichev State Research and Production Space Center and marketed by International Launch Services (ILS).
After reaching an altitude of about 161 km (100 mi) the rocket and Mexsat 1 payload fell back to Earth and burned up over the Chita region of Russia, which is located south west of the Siberian Baikal region, said the Russian News agency TASS.
“The rocket and its payload, a Mexican communication satellite, burned up in the atmosphere,” according to a report by Sputnik International, a Russian News agency.
At this time, local residents have not reported or claimed anything regarding possible debris and there is no information about casualties or destruction, TASS noted.
Mi8 helicopters from Russia’s Emergencies Ministry have been dispatched to the area to look for any debris.
The 5.4 ton Mexsat 1 communication satellite was built by Boeing Satellite Systems International for the Mexican government’s Ministry of Communications and Transportation, the Secretaria de Comunicaciones y Transportes (SCT).

The Breeze-M failure occurred about 1 minute prior to separation of the third stage from Mexsat 1.
“The emergency situation happened at 08:56 Moscow time, one minute to the scheduled separation of the Breeze-M booster and the Mexican MexSat-1 space apparatus,” TASS reported.
A malfunction with the third stage steering engine may be the cause of the doomed flight.
“A preliminary reason of the accident with Proton is a failure of the steering engines of the third stage,” sources told TASS.
“The analysis of the telemetry allows for supposing that there was a failure in one of the third stage’s steering engines. This is now considered as one of the main reasons.”
Exactly one year ago, another Proton rocket crashed at a similar point when the third stage engines failed during the Proton launch of Russia’s advanced Express-AM4R satellite.
“Khrunichev and International Launch Services (ILS) regret to announce an anomaly during today’s Proton mission,” ILS said in a statement issued after the launch failure.
ILS said an accident investigation board has been appointed to determine the cause of the failure and recommend corrective actions.
“A Russian State Commission has begun the process of determining the reasons for the anomaly. ILS will release details when data becomes available,” said ILS.
They hope to return the workhorse Proton to flight as soon as possible.
“ILS remains committed to providing reliable, timely launch services for all its customers. To this end, ILS will work diligently with its partner Khrunichev to return Proton to flight as soon as possible.”
This was the eleventh failure of the Proton-M rocket or Breeze-M upper stage in 116 launches since the inaugural liftoff in April 2001.
Mexsat 1 had a planned lifetime of 15 years. It was to provide mobile satellite services to support national security, civil and humanitarian efforts and will provide disaster relief, emergency services, telemedicine, rural education, and government agency operations.
Media reports indicate it was insured for about $390 million.

Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
Congratulations: perhaps you’re a new space-faring nation, looking to place a shiny new payload around the planet Earth. You’ve assembled the technical know-how, and seek to break the surly bonds and join an exclusive club that thus far, only contains 14 nations capable of indigenous spaceflight. Now for the big question: which orbit should you choose?
Welcome to the wonderful world of orbital mechanics. Sure, satellites in orbit have to follow Newton’s laws of motion, as they perpetually ‘fall’ around the Earth without hitting it. But it’ll cost you in fuel expended and technical complexity to achieve different types of orbits. Different types of orbits can, however, be used to accomplish different goals.
The first artificial moon to be placed in low-Earth orbit was Sputnik 1 launched on October 4th, 1957. But even before the dawn of the Space Age, visionaries such as futurist and science fiction author Arthur C. Clarke realized the value of placing a satellite in a geosynchronous orbit about 35,786 kilometres above the Earth’s surface. Placing a satellite in such an orbit keeps it in ‘lockstep’ with the Earth rotating below it once every twenty four hours.
Here are some of the more common orbits targeted by modern satellites and their uses:
Different orbits versus altitude. Image credit: Wikimedia Commons/Cmglee, Geo Swan
Low-Earth Orbit (LEO): Placing a satellite 700 km above the surface of the Earth moving 27,500 km per hour will cause it to orbit the Earth once every 90 minutes. The International Space Station is in just such an orbit. Satellites in LEO are also subject to atmospheric drag, and must be boosted periodically. Launching from the equator of the Earth gives you an initial free maximum 1,670 km/per hour boost into orbit eastward. Incidentally, the high 52 degree inclination orbit of the ISS is a compromise that assures that it is reachable from various launch sites worldwide.

Low Earth orbit is also becoming crowded with space junk, and incidents such as the successful 2007 anti-satellite missile test by China, and the 2009 collision of Iridium 33 and the defunct Kosmos-2251 satellite both showered low Earth orbit with thousands of extra pieces of debris and didn’t help the situation much. There have been calls to make reentry technology standard on future satellites, and this will become paramount with the advent of flocks of nano and CubeSats in LEO.
Still up there: The orbital trace of China’s space station Tiangong-1: Image credit: Orbitron
Sun-Synchronous Orbit: This is a highly inclined retrograde orbit that assures that the illumination angle of the Earth below is consistent on multiple passes. Though it takes a fair amount of energy to reach a Sun-synchronous orbit—plus a complex deployment maneuver known as a ‘dog leg’—this type of orbit is desirable for Earth observing missions. It’s also a favorite for spy satellites, and you’ll notice that many nations aiming to put up their first satellites will use the stated goal of ‘Earth observation’ to field spy satellites of their own.
Molyina orbit: A highly inclined elliptical orbit designed by the Russians, a Molyina orbit takes 12 hours to complete, placing the satellite over one hemisphere for 2/3rds of its orbit and returning it back over the same geographical point once every 24 hours.
A semi-synchronous orbit: A 12-hour elliptical orbit similar to a Molyina orbit, a semi-synchronous orbit is favored by Global Positioning Satellites.

Geosynchronous orbit: The aforementioned point 35,786 km above the Earth’s surface where a satellite stays fixed over a particular longitude.
Geostationary orbit: Place a GEO satellite in orbit with a zero degree orbit, and it is considered Geostationary. Also sometimes referred to as a Clarke orbit, this location is extremely stable, and satellites placed there may remain in orbit for millions of years.
In 2012, the EchoStar XVI satellite was launched headed to GEO with the time capsule disk The Last Pictures for just that reason. It is quite possible that millions of years from now, GEO sats might be the primary artifacts remaining from the early 20th/21st century civilization.
Lagrange point orbits: 18th century mathematician Joseph-Louis Lagrange made the observation that several stable points exist in any three body system. Dubbed Lagrange points, these locales serve as great stable positions to place observatories. The Solar Heliospheric Observatory (SOHO) sits at the L1 point to afford it a continuous view of the Sun; the James Webb Space Telescope is bound in 2018 for the L2 point beyond the Moon. To stay on station near a LaGrange point, a satellite must enter a Lissajous or Halo orbit around the imaginary Lagrange point in space.
All of these orbits have pros and cons. For example, atmospheric drag isn’t an issue in geosynchronous orbit, though it takes several boosts and transfer orbit maneuvers to attain. And as with any plan, complexity also adds more chances for things to fail, stranding a satellite in the wrong orbit. Russia’s Phobos-Grunt mission suffered just such a fate after launch in 2011 when its Fregat upper stage failed to operate properly, stranding the interplanetary spacecraft in Earth orbit. Phobos-Grunt crashed back to Earth over the Southern Pacific on January 15th, 2012.
Space is a tough business, and it’s imperative to place things in the right orbit!

KENNEDY SPACE CENTER, FL – A state of the art quartet of identical science satellites aimed at unraveling the mysteries of the process known as magnetic reconnection is slated for a spectacular nighttime blastoff tonight, March 12, atop a United Launch Alliance Atlas V rocket on Cape Canaveral, Florida.
The $1.1 Billion Magnetospheric Multiscale (MMS) mission is comprised of four formation flying and identically instrumented observatories whose objective is providing the first three-dimensional views of a fundamental process in nature known as magnetic reconnection.
Magnetic reconnection is a little understood natural process whereby magnetic fields around Earth connect and disconnect while explosively releasing vast amounts of energy. It occurs throughout the universe.
Liftoff is slated for 10:44 p.m. EDT Thursday March 12 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida.
The launch window extends for 30 minutes. You can watch the MMS launch live on NASA TV, below, starting at 8 p.m.
Spectators ringing the Florida space coast region and ranging well beyond should be treated to a magnificent fireworks display and skyward streak of perhaps several minutes – weather and clouds permitting.
Currently the weather forecast is 70 percent “GO” for favorable conditions at launch time. The primary concerns for a safe and successful launch are for cumulus clouds and thick clouds.
In the event of a 24 hour delay for any reason the weather forecast is 60 percent “GO.”

The 195 foot tall rocket and encapsulated MMS satellite payload were rolled out to Space Launch Complex-41 on Wednesday March 10 at 10 a.m. on the Mobile Launch Platform (MLP) about 1800 feet from the Vertical Integration Facility or VIF to the Cape Canaveral pad.
The two stage Atlas V rocket will deliver the MMS constellation to a highly elliptical orbit.
The venerable rocket with a 100% success rate will launch in the Atlas V 421 configuration with a 4-meter diameter Extra Extended Payload Fairing along with two Aerojet Rocketdyne solid rocket motors attached to the Atlas booster first stage.

The Atlas first stage is powered by the RD AMROSS RD-180 engine and the Centaur upper stage is powered by the Aerojet Rocketdyne RL10A engine producing 22,300 lb of thrust.
The first stage is 12.5 ft in diameter and fueled with liquid propellants. The RD-180 burns RP-1 highly purified kerosene and liquid oxygen and delivers 860,200 lb of sea level thrust.
This is ULA’s 4th launch in 2015, the 53nd Atlas V mission and the fourth Atlas V 421 launch.
“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.”
After a six month check out phase the probes will start science operation 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 four probes were built in-house by NASA at the agency’s Goddard Space Flight Center in Greenbelt, Maryland where I visited them during an inspection tour by NASA Administrator Charles Bolden.
I asked Bolden to explain the goals of MMS during a one-on-one interview.
“MMS will help us study the phenomena known as magnetic reconnection and help us understand how energy from the sun – magnetic and otherwise – affects our own life here on Earth,” Bolden told Universe Today.
“MMS will study what effects that process … and how the magnetosphere protects Earth.”
MMS measurements should lead to significant improvements in models for yielding better predictions of space weather and thereby the resulting impacts for life here on Earth as well as for humans aboard the ISS and robotic satellite explorers in orbit and the heavens beyond.
The best place to study magnetic reconnection is ‘in situ’ in Earth’s magnetosphere. This will lead to better predictions of space weather phenomena.
Magnetic reconnection is also believed to help trigger the spectacular aurora known as the Northern or Southern lights.

NASA’s first mission dedicated to study the process in nature known as magnetic reconnection undergoing final preparation for launch from Cape Canaveral, Florida in just under two weeks time.
The Magnetospheric Multiscale (MMS) mission is comprised of a quartet of identically instrumented observatories aimed at providing the first three-dimensional views of a fundamental process in nature known as magnetic reconnection.
Magnetic reconnection is the process whereby magnetic fields around Earth connect and disconnect while explosively releasing vast amounts of energy. It occurs throughout the universe.
“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 four MMS have been stacked on top of one another like pancakes, encapsulated in the payload fairing, transported to the launch pad, hoisted and mated to the top of the 195-foot-tall rocket.

The nighttime launch of MMS on a United Launch Alliance Atlas V rocket should put on a spectacular sky show for local spectators along the Florida space coast as well as more distant located arcing out in all directions.
Liftoff is slated for 10:44 p.m. EDT Thursday March 12 from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida.
