There’s solid evidence for the existence of water on Mars, at least in frozen form at the planet’s poles. And a more recent study confirms the existence of liquid water at the south pole. But visitors to Mars will need to know the exact location of usable water deposits at other Martian locations. A ground-penetrating radar called ScanMars may be up to the task.
Have you checked out Mars this season? Mars reaches opposition on July 27th at 5:00 Universal Time (UT) shining at magnitude -2.8 and appearing 24.3” across—nearly as large as it can appear, and the largest since the historic opposition of 2003. We won’t have an opposition this favorable again until September 15th, 2035.
Mars starts this week near the +4th magnitude star Psi Capricorni, loops westward through retrograde briefly into the astronomical constellation of Sagittarius the Archer in late August before heading back into Capricornus in September.
Mars opened up 2018 just 4.8” across, trekking through the early dawn sky. What a difference a few months make: Mars broke 15” arc seconds—a maximum size for an unfavorable opposition near aphelion—on May 30th, and now dominates the summer sky around midnight.
There’s one downside, however, to the 2018 opposition of Mars: it’s occurring very nearly as far south along the ecliptic as it can. This is great news for observers in Australia, South Africa and South America, as the Red Planet rides high near the zenith at local midnight. Up north, however, we are still looking at Mars through the murk of the atmosphere lower to the horizon. For example, here in Norfolk, Virginia at latitude 37 degrees north, we never see Mars rise more than 29 degrees altitude above the southern horizon this season.
Down with Dust Storms
Does Mars seem a bit… peachy colored to you this season? It’s not your imagination: a planetary dust storm is indeed underway. It’s the middle of autumn for northern hemisphere of Mars, and this seems to be shaping up to be one of those oppositions where the planet, though at its closest, presents a featureless, dust-shrouded disk. This seems to be the case roughly every third opposition or so… our best hope now is that it may clear in the coming final weeks of July. We checked out Mars over the past weekend, and could just spy the pole cap and some slight detail under a veil of haze.
Despite the depiction of Martian dust storms in science fiction blockbusters such as The Martian as furious and unrelenting, these storms are actually pretty mild-mannered, barely able to chase a leaf before them through the tenuous Martian atmosphere, if deciduous trees grew on Mars. One thing Martian dust storms can do, however, is coat solar panels with a battery-killing film, and it has yet to be seen if the aging Opportunity rover will awaken and phone home from Meridiani Planum.
Unlike the Earth, Mars has a markedly elliptical orbit, varying from 1.7 (AU) astronomical units from the Sun at aphelion to 1.4 AU near perihelion. This all means that not every opposition of Mars is equal; in fact, Mars can range from 55 million to 102 million kilometers from the Earth near opposition and appear 13.8” to 25.1” across, depending on where it’s at in its orbit. And although Mars laps the Earth roughly every 26 months, a cycle of favorable oppositions repeat every 15 years.
In 2018, Mars reaches opposition on July 27th at 5:00 UT/1:00 AM EDT 57.8 million kilometers from the Earth, then makes its closest approach four days later on July 31st at 8:00 UT/4:00 AM EDT, 57.6 million kilometers distant. Why the discrepancy? Well, opposition is simply reckoned as the point where an outer planet reaches an ecliptic longitude of 180 degrees opposite from the Sun. Mars, however, is still headed inward towards perihelion on September 16th, while Earth just came off of aphelion on July 6th.
Visually, Mars can on occasion “go yellow” and present a saffron color even to the naked eye if a planetary wide sandstorm is underway. At the eyepiece, the most prominent feature is always the pole cap, a white dollop on the planet’s pumpkin hued limb. Crank up the magnification, and dark patches come into view, as Mars is the only planet in the solar system presenting an actual surface available for amateur scrutiny. Mars has a day very similar to Earth’s at only 37 minutes longer in duration, meaning that if you observe Mars at the same time every evening, you’ll see nearly the same longitude of the planet turned towards you, shifted 10 degrees westward. A great tool for comparing what features on Mars are currently turned Earthward is Mars Previewer.
Can you spy Mars… daytime? This month is a good time to try, as it currently shines brighter than Jupiter. The easiest thing to do is lock on to it with a telescope near dawn as it sets to the west and the Sun rises in the east, then simply track it into the daytime sky. We’ve seen Mars in 2003 and again this year while the Sun is still above the horizon… having the Moon nearby also helps, though of course, Mars is very close to the horizon at sunset/sunrise right at opposition.
And speaking of which, viewers in Europe, Africa, Asia and Australia are in for a special treat on the evening of July 27th, as a total eclipse of the Moon occurs just 15 hours after Mars passes opposition. Ironically, this is also a Minimoon eclipse, as the Moon also passes apogee just 14 hours prior to entering the Earth’s shadow. Expect to see the Red Planet just seven degrees from the blood red Moon at mid-eclipse (more on the eclipse next week).
The Moon won’t occult (pass in front of) Mars again until November 16th, 2018 for the very southernmost tip of South America. Stick around until July 26th, 2344 AD, and you can witness the Moon occulting the planet Saturn during an eclipse, though you’ll have to journey to southern Japan to do it.
But you may not have to wait that long… stick around until April 27th, 2078, and you can witness the Moon occult Mars… during a penumbral lunar eclipse:
This current evening apparition of Mars ends over a year from now on September 2nd, 2019, as Mars reaches solar conjunction on the farside of the Sun.
Finally, opposition is a great time to try and check the tiny Martian moons Phobos and Deimos off of your life list. These two moons were actually discovered by Asaph Hall from the United States Naval Observatory’s newly installed 26-inch refractor during a favorable parihelic apparition of Mars in 1877.
Shining at magnitude +12.4 (Deimos) and +11.3 (Phobos), seeing these moons would be a cinch… were it not for the presence of Mars shining a million times brighter nearby. Your best bet is to construct an occulting bar eyepiece (we’ve used a thin strip of foil and a guitar string affixed to an eyepiece to accomplish this) or simply place brilliant Mars just out of view. Phobos orbits once every 7.7 hours and substends 20” from the disk of Mars, while Deimos goes around Mars once every 30.35 hours and journeys 66” with each elongation from the Martian disk. PDS rings node or a good planetarium program such as Starry Night or Stellarium will show the current orientation of the Martian moons, aiding in your decision of whether or not to take up the quest.
Don’t miss out on Mars this opposition season… it’ll be almost another two decades before we get another favorable view.

History was made on July 20th, 1969, when Apollo 11 astronauts Neil Armstrong and Buzz Aldrin set foot on the surface of the Moon. The moment was the culmination of decades of hard work, research, development and sacrifice. And since that time, human beings have been waiting and wondering when we might achieve the next great astronomical milestone.
So really, when will we see a man or woman set foot on Mars? The prospect has been talked about for decades, back when NASA and the Soviets were still planning on setting foot on the Moon. It is the next logical step, after all. And at present, several plans are in development that could be coming to fruition in just a few decades time.
Werner Von Braun, the (in)famous former Nazi rocket scientist – and the man who helped spearhead NASA’s Project Mercury – was actually the first to develop a concept for a crewed mission to Mars. Titled The Mars Project (1952), his proposal called for ten spacecraft (7 passenger, 3 cargo) that would transport a crew of 70 astronauts to Mars.
His proposal was based in part on the large Antarctic expedition known as Operation Highjump (1946–1947), a US Navy program which took place a few years before he started penning his treatise. The plan called for the construction of the interplanetary spacecraft in around the Earth using a series of reusable space shuttles.
He also believed that, given the current pace of space exploration, such a mission could be mounted by 1965 (later revised to 1980) and would spend the next three years making the round trip mission. Once in Mars orbit, the crew would use telescopes to find a suitable site for their base camp near the equator.
A landing crew would then descend using a series of detachable winged aircraft (with ski landing struts) and glide down to land on the polar ice caps. A skeleton crew would remain with the ships in orbit as the surface crew would then travel 6,500 km overland using crawlers to the identified base camp site.
They would then build a landing strip which would allow the rest of the crew to descend from orbit in wheeled gliders. After spending a total of 443 days on Mars conducting surveys and research, the crew would use these same gliders as ascent craft to return to the mother ships.
Von Braun not only calculated the size and weight of each ship, but also how much fuel each would require for the round trip. He also computed the rocket burns necessary to perform the required maneuvers. Because of the detailed nature, calculations and planning in his proposal, The Mars Project remains one of the most influential books on human missions to the Red Planet.
Obviously, such a mission didn’t happen by 1965 (or 1980 for that matter). In fact, humans didn’t even return to the Moon after Eugene Cernan climbed out of the Apollo 17 capsule in 1972. With the winding down of the Space Race and the costs of sending astronauts to the Moon, plans to explore Mars were placed on the backburner until the last decade of the 20th century.
In 1990, a proposal called Mars Direct was developed by Robert Zubrin, founder of the Mars Society and fellow aerospace engineer David Baker. This plan envisioned a series of cost-effective mission to Mars using current technology, with the ultimate goal of colonization.
The initial missions would involve crews landing on the surface and leaving behind hab-structures, thus making subsequent missions easier to undertake. In time, the surface habs would give way to subsurface pressurized habitats built from locally-produced Martian brick. This would represent a first step in the development of in-situ resource utilization, and eventual human settlement.
During and after this initial phase of habitat construction, hard-plastic radiation- and abrasion-resistant geodesic domes would be deployed to the surface for eventual habitation and crop growth. Local industries would begin to grow using indigenous resources, which would center around the manufacture of plastics, ceramics and glass out of Martian soil, sand and hydrocarbons.
While Zubrin acknowledged that Martian colonists would be partially Earth-dependent for centuries, he also stated that a Mars colony would also be able to create a viable economy. For one, Mars has large concentrations of precious metals that have not been subjected to millennia of human extracting. Second, the concentration of deuterium – a possible source for rocket fuel and nuclear fusion – is five times greater on Mars.
In 1993, NASA adopted a version of this plan for their “Mars Design Reference” mission, which went through five iterations between 1993 and 2009. And while it involved a great deal of thinking and planning, it failed to come up with any specific hardware or projects.
Things changed in the 21st century after two presidential administrations made fateful decisions regarding NASA. The first came in 2004 when President George W. Bush announced the “Vision for Space Exploration“. This involved retiring the Space Shuttle and developing a new class of launchers that could take humans back to the Moon by 2020 – known as the Constellation Program.
Then, in February of 2010, the Obama administration announced that it was cancelling the Constellation Program and passed the Authorization Act of 2010. Intrinsic to this plan was a Mars Direct mission concept, which called for the development of the necessary equipment and systems to mount a crewed mission to Mars by the 2030s.
In 2015, NASA’s Human Exploration and Operations Mission Directorate (HEOMD) presented the “Evolvable Mars Campaign”, which outlined their plans for their “Journey to Mars’ by the 2030s. Intrinsic to this plan was the use of the new Orion Multi-Purpose Crew Vehicle (MPCV) and the Space Launch System (SLS).
The proposed journey would involve Three Phases, which would involve a total of 32 SLS launches between 2018 and the 2030s. These missions would send all the necessary components to cis-lunar space and then onto near-Mars space before making crewed landings onto the surface.
Phase One (the “Earth Reliant Phase”) calls for long-term studies aboard the ISS until 2024, as well as testing the SLS and Orion Crew capsule. Currently, this involves the planned launch of Exploration Mission 1 (EM-1) in Sept. of 2018, which will be the first flight of the SLS and the second uncrewed test flight of the Orion spacecraft.
NASA also plans to capture a near=Earth asteroid and bring it into lunar orbit, as a means of testing the capabilities and equipment for a Mars mission. Known as the Asteroid Redirect Mission, this mission is scheduled to take place in the 2020s and would primarily involve a robotic mission towing the asteroid and returning samples.
Exploration Mission 2 (EM-2), the first crewed flight using the Orion capsule, would conduct a flyby around the Moon and this asteroid between 2021 and 2023. At this point, NASA would be moving into Phase Two (“Proving Ground”) of the Journey to Mars, where the focus would move away from Earth and into cis-lunar space.
Multiple SLS launches would deliver the mission components during this time – including a habitat that would eventually be transported to Martian orbit, landing craft, and exploration vehicles for the surface of Mars. This phase also calls for the testing of key technologies, like Solar Electric Propulsion (aka. the ion engine).
By the early 2030s, Phase Three (“Earth Independent”) would begin. This calls for testing the entry, descent and landing techniques needed to get to the Martian surface, and the development of in-situ resource utilization. It also calls for the transferring of all mission components (and an exploration crew) to Martian orbit, from which the crews would eventually mount missions to designated “Exploration Zones” on the surface.
On Sept. 15th, 2016, the Senate Committee on Commerce, Science, and Transportation passed the NASA Transition Authorization Act of 2016, a measure designed to ensure short-term stability for the agency in the coming year.
The European Space Agency (ESA) has long-term plans to send humans to Mars, though they have yet to build a manned spacecraft. As part of the Aurora Program, this would involve a crewed mission to Mars in the 2030s using an Ariane M rocket. Other key points along that timeline include the ExoMars rover (2016-2020), a crewed mission to the Moon in 2024, and an automated mission to Mars in 2026.
Roscosmos, the Russian Federal Space Agency, is also planning a crewed mission to Mars, but doesn’t envision it happening until between 2040 and 2060. In the meantime, they have conducted simulations (called Mars-500), which wrapped up in Russia back in 2011. The Chinese space agency similarly has plans to mount a crewed mission to Mars between 2040 and 2060, but only after crewed missions to Mars take place.
In 2012, a group of Dutch entrepreneurs revealed plans for a crowdfunded campaign to establish a human Mars base, beginning in 2023. Known as MarsOne, the plan calls for a series of one-way missions to establish a permanent and expanding colony on Mars, which would be financed with the help of media participation.
Other details of the MarsOne plan include sending a telecom orbiter by 2018, a rover in 2020, and the base components and its settlers by 2023. The base would be powered by 3,000 square meters of solar panels and the SpaceX Falcon 9 Heavy rocket would be used to launch the hardware. The first crew of 4 astronauts would land on Mars in 2025; then, every two years, a new crew of 4 astronauts would arrive.
SpaceX and Tesla CEO Elon Musk has also announced plans to establish a colony on Mars in the coming decades. Intrinsic to this plan is the development of the Mars Colonial Transporter (MCT), a spaceflight system that would rely of reusable rocket engines, launch vehicles and space capsules to transport humans to Mars and return to Earth.
As of 2014, SpaceX has begun development of the large Raptor rocket engine for the Mars Colonial Transporter, and a successful test was announced in September of 2016. In January 2015, Musk said that he hoped to release details of the “completely new architecture” for the Mars transport system in late 2015.
In June 2016, Musk stated in the first unmanned flight of the MCT spacecraft would take place in 2022, followed by the first manned MCT Mars flight departing in 2024. In September 2016, during the 2016 International Astronautical Congress, Musk revealed further details of his plan, which included the design for an Interplanetary Transport System (ITS) – an upgraded version of the MCT.
According to Musk’s estimates, the ITS would cost $10 billion to develop and would be ready to ferry the first passengers to Mars as early as 2024. Each of the SpaceX vehicles would accommodate 100 passengers, with trips being made every 26 months (when Earth and Mars are closest). Musk also estimated that tickets would cost $500,000 per person, but would later drop to a third of that.
And while some people might have a hard time thinking of MarsOne’s volunteers or SpaceX’s passengers as astronauts, they would nevertheless be human beings setting foot on the Red Planet. And if they should make it there before any crewed missions by a federal space agency, are we really going to split hairs?
So the question remains, when will see people sent to Mars? The answer is, assuming all goes well, sometime in the next two decades. And while there are plenty who doubt the legitimacy of recent proposals, or the timetables they include, the fact that we are speaking about going to Mars a very real possibility shows just how far we’ve come since the Apollo era.
And does anyone need to be reminded that there were plenty of doubts during the “Race to the Moon” as well? At the time, there were plenty of people claiming the resources could be better spent elsewhere and those who doubted it could even be done. Once again, it seems that the late and great John F. Kennedy should have the last word on that:
“We choose to go to the Moon! … We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”
We’ve written many articles about humans traveling to Mars. Here’s how new technology might slash the time to travel to Mars down to 39 days, and here’s an article about a team that did a simulated Mars mission.

The 2016 launch window for Mars missions is fast approaching along with opposition, and ESA is refining its target window for ExoMars. Mars launch season offers the optimal time to make the trip from Earth to Mars, as missions prepare to break the surly bonds and head towards the Red Planet next spring. NASA’s InSight lander will also make the trip.
ExoMars is the first joint European Space Agency (ESA) Roscosmos mission to the Red Planet. The ExoMars Trace Gas Orbiter is under contract to Thales Alenia Space, and the EDM stationary lander dubbed Schiaparelli after the 19th century Italian astronomer is being constructed by Airbus Defense and Space. This would be Russia’s first successful Mars lander mission for over a dozen tries if successful.
The ExoMars project is a two-part mission, and will culminate in an ExoMars rover in 2018. The key objective for the Trace Gas Orbiter, lander and rover to follow in 2018 is to seek out the controversial source of methane on Mars. A product of biology—think bovine flatulence—on Earth, researchers have proposed various sources—inorganic and otherwise—as a source of the anomalous methane seen in the Martian atmosphere. The Trace Gas Orbiter will remain on-station in orbit through 2018 to relay communications from the ExoMars rover. The Entry, Descent and Landing Demonstrator Module Schiaparelli will demonstrate key technologies for landing, including a hybrid Buck Rodgers fins-first style retro-rocket landing reminiscent of Viking, along with a deformable underside meant to absorb impact.
The landing with be a dramatic one on Meridiani Planum at the expected height of dust storm season, and we may get some interesting footage from the onboard descent camera. Along with weather and atmospheric measurements, the EDM Lander will also make the first electrical field measurements from the surface of Mars.
Unfortunately, EDM’s life will be short; Roscosmos originally intended to supply a 100-watt plutonium-powered RTG for the lander, but later opted due to export control to use an on-board battery. The EDM’s lifespan will be measured in a few days, at best.
Heading to Mars in 2016
An issue related to two propulsion system sensors aboard the EDM Lander recently prompted mission planners to opt for a launch for ExoMars at the end of the window next year, with liftoff set for March 14th atop a Proton rocket from the Baikonur Cosmodrome in Kazakhstan instead of January, as originally intended. NASA’s Mars InSight will depart Earth for the Red Planet just ten days earlier on March 4th from Vandenberg AFB in a rare dramatic night shot of an Atlas 5 rocket deploying an interplanetary mission from the US West Coast. InSight’s primary objective is to study seismic activity and the Martian interior, and will land in one of four selected sites (1 primary and 3 backup) in Elysium Planitia on September 28th, 2016.
Naturally, ESA and Roscomos are taking every precaution to assure the success of ExoMars and EDM. The 2011 failure of Phobos-Grunt highlighted the perils of tempting the ‘Great Martian Ghoul’ with more tasty spacecraft. Space is hard, and landing on Mars even more so.
Opposition 2016 for Mars occurs on May 22nd, 2016. Mars is always high in the early morning sky a few months prior to opposition, presenting an optimal window to send spacecraft to the Red Planet on the most efficient in trajectory in terms of fuel and time. This 3-month wide window comes around every 26 months leading up to opposition season. Oppositions of Mars are now getting more favorable, and the next opposition after 2016 in 2018 will be nearly as favorable as the historic 2003 event.
Our robots are swiftly colonizing Mars on our behalf. Here’s a Who’s Who scorecard of functioning spacecraft. On the surface: NASA’s Opportunity and Mars Curiosity rovers. In orbit: Mars Odyssey, (Since 2001!) Mars Express, HiRISE, India’s Mars Orbiter, and MAVEN. Add the ExoMars 2016 and 2018 missions, InSight and the Mars 2020 rover for NASA, and we’ve truly established a redundant sort of ‘telepresence’ on and around Mars.
Will the EDM Lander become the first successful non-NASA lander to approach the Red Planet? Keep an eye on the Insight and the first of two ExoMars missions, as Earth invades Mars in 2016!
The final chapter in the saga of a wayward Mars lander was finally revealed today, as an international team released images showing the Beagle-2 lander’s final resting place on Mars.
Flashback to Christmas Day, 2003. While most folks gathered ‘round the tree and opened presents, the UK and European Space Agency awaited a gift from space. The Beagle-2 Mars lander had been released from the European Space Agency’s Mars Express orbiter six days prior, and was coasting towards a perilous landing in Isidis Planitia and was set to phone home.
All was going according to plan, and then… silence.
It’s the worst part of any mission, waiting for a lander to call back and say that it’s safe and sound on the surface of another world. As the hours turned into days, anxious engineers used NASA’s Mars Odyssey spacecraft and the Lovell Telescope at Jodrell Bank to listen for the signal.
Beagle-2 was declared lost a few weeks later on February 6th, 2004.
But now, there’s a final twist to the tale to tell.
The UK Space Agency, working with ESA and NASA announced today that debris from the landing site had been identified and that indicates — contrary to suspicions — that Beagle-2 did indeed make it to the surface of the Red Planet intact. New images from the Mars Reconnaissance Orbiter released today suggest that not only did Beagle-2 land, but that its airbags did indeed deploy properly and that the dish-shaped 1-meter in diameter spacecraft partially unfolded pocket-watch style after it had bounced to a stop.
“We are very happy to learn that Beagle 2 touched down on Mars,” said ESA’s Director of Science and Robotic Exploration in a recent press release. “The dedication of the various teams in studying high-resolution images in order to find the lander is inspiring.”
So, what went wrong with Beagle-2?
At this point, no further speculation as to what caused the lander to fall silent has been forthcoming, but today’s revelation is sure to rewrite the final saga of Beagle-2.
“Not knowing what happened to Beagle-2 remained a nagging worry,” said ESA’s Mars Express project manager Rudolf Schmidt. “Understanding now that Beagle-2 made it all the way down to the surface is excellent news.”
Speculation swirled across the internet earlier this week as the UK Space Agency and ESA suggested that new information as to the fate of Beagle-2 was forthcoming, over 11 years after the incident. Back in 2004, it was suggested that Beagle-2 had encountered higher levels of dust in the Martian atmosphere than expected, and that this in turn resulted in a failure of the spacecraft’s parachutes. Presumably, the lander then failed to slow down sufficiently and crashed on the surface of Mars, the latest victim of the Great Galactic Ghoul who seems to love dining on human-built spacecraft bound for the Red Planet.
The loss of Beagle-2 wasn’t only a blow to the UK and ESA, but to its principal investigator Colin Pillinger as well. Pillinger was involved in the search for Beagle-2 in later years, and also played a part in the Rosetta mission to Comet 67P/Churyumov-Gerasimenko as well. Unfortunately, Pillinger passed away in May of last year from a brain hemorrhage. A portion of the western rim of Endeavour Crater currently being explored by Opportunity was named Pillinger Point in his honor.
Today’s announcement has triggered a wave of congratulations that the 11-year mystery has been solved. There have even been calls on Twitter and social media to rename the Beagle-2 site Pillinger Station.
“The history of of space exploration is marked by both success and failure,” Said Dr. David Parker, the Chief Executive of the UK Space Agency in a recent press release. “This finding makes the case that Beagle-2 was more of a success than we previously knew and undoubtedly an important step in Europe’s continuing exploration of Mars.”
Beagle-2 is about 2 metres across unfurled, and came to rest within 5 kilometres of its target location.
There have been false announcements of the discovery of Beagle-2 before. Back in late 2005, a claim was made that the lander had been spotted by Mars Global Surveyor, though later searches came to naught.
“I can imagine the sense of closure that the Beagle-2 team must feel,” Said JPL’s MRO project scientist Richard Zurek in a recent press release. “MRO has helped find safe landing sites on Mars for the Curiosity and Phoenix missions and has searched for missing craft to learn what may have gone wrong. It’s an extremely difficult task.”
MRO entered orbit in March 2006 and carries a 0.5 metre in diameter HiRISE camera capable of resolving objects just 0.3 metres across on the surface of Mars. The European Space Agency’s Mars Express orbiter that carried Beagle 2 is also still in operation, along with NASA’s aging Mars Odyssey spacecraft. These were joined in orbit by MAVEN and India’s Mars Orbiter just last year.
Of course, getting to Mars is tough, and landing is even harder. Mars has just enough atmosphere that you have to deal with it, but it’s so tenuous – 0.6% the surface pressure of Earth’s atmosphere at sea level – That it doesn’t provide a whole lot of usable drag.
To date, only NASA had successfully landed on Mars, and done it seven times – only the Mars Polar Lander failed back in 1999. The Russians fared much worse, with their most successful lander being Mars 3, which sent back only one blurry image before falling silent.
ESA and the Russian Federal Space Agency hope to amend that with the launch of the ExoMars mission next year, slated to land on Mars in 2018.
I remember waiting with millions of other space fans for word back from Beagle 2 on Christmas Day 2003. Think back to what your internet connection was like over 11 years ago, in an era before smart phones, Twitter and Facebook. We’d just come off of the spectacular 2003 Mars opposition season, which provided the orbital geometry ideal for launching a mission to the Red Planet. This window only comes around once every 26 months.
Though Beagle 2 was a stationary lander akin to the Viking and Mars Phoenix missions, it had a robotic arm and a clever battery of experiments, including ones designed to search for life. The signal it was supposed to use to call home was designed by the UK pop rock band Blur, a jingle that never came.
Alas, we’ll have to wait to see what the alien plains around Isidis Planitia actually look like, just 13 degrees north of the Martian equator. But hey, a lingering mystery of the modern age of planetary exploration was solved this week.
Still, we’re now left with a new dilemma. Does this mean we’ll have to write a sequel to our science fiction short story The Hunt for Beagle?
Fans of Mars and spaceflight waxed poetic as the haiku selected to travel to Mars aboard the MAVEN spacecraft were announced earlier this month.
The contest received 12,530 valid entries from May 1st through the contest cutoff date of July 1st. Students learned about Mars, planetary exploration and the MAVEN mission as they composed haiku ranging from the personal to the insightful to the hilarious.
“The contest has resonated with people in ways that I never imagined! Both new and accomplished poets wrote poetry to reflect their views of Earth and Mars, their feelings about space exploration, their loss of loved ones who have passed on, and their sense of humor,” said Stephanie Renfrow, MAVEN Education & Public Outreach & Going to Mars campaign lead.
A total of 39,100 votes were cast in the contest; all entries receiving more than 2 votes (1,100 in all) will be carried on a DVD affixed to the MAVEN spacecraft bound for Martian orbit.
Five poems received more than a thousand votes. Among these were such notables as that of one 8th grader from Denver Colorado, who wrote;
Phobos & Deimos
Moons orbiting around Mars
Snared by Gravity
Another notable entry which was among the poems sited for special recognition by the MAVEN team was that of Allison Swets of Michigan;
My body can’t walk
My mouth can’t make words but I
Soar to Mars today
377 artwork entries were also selected to fly aboard MAVEN as well.
Didn’t get picked? There’s still time to send your name aboard MAVEN along with thousands that have already been submitted. You’ve got until September 10!
Part of NASA’s discontinued Scout-class of missions, the Mars Atmosphere and Volatile EvolutioN mission, or MAVEN, is due to launch out of Cape Canaveral on November 18th, 2013. Selected in 2008, MAVEN has a target cost of less than $500 million dollars US, not including launch carrier services atop an Atlas V rocket in a 401 flight configuration.
The Phoenix Lander was another notable Scout-class mission that was extremely successful, concluding in 2008.
Principal investigator for MAVEN is the University of Boulder at Colorado’s Bruce Jakosky of the Laboratory for Atmospheric and Space Physics (LASP).
The use of poetry to gain public interest in the mission is appropriate, as MAVEN seeks to solve the riddle that is the Martian atmosphere. How did Mars lose its atmosphere over time? What role does the solar wind play in stripping it away? And what is the possible source of that anomalous methane detected by Mars Global Surveyor from 1999 to 2004?
MAVEN is based on the design of the Mars Odyssey and Mars Reconnaissance Orbiter spacecraft. It will carrying an armada of instruments, including a Neutral Gas & Ion Mass Spectrometer, a Particle and Field Package with several analyzers, and a Remote Sensing Package built by LASP.
MAVEN just arrived at the Kennedy Space Center earlier this month for launch processing and mating to its launch vehicle. Launch will be out of Cape Canaveral Air Force Station on November 18th with a 2 hour window starting at 1:47 PM EST/ 18:47 UT.
Assuming that MAVEN launches at the beginning of its 20 day window, it will reach Mars for an orbital insertion on September 22, 2014. MAVEN will orbit the Red Planet in an elliptical 150 kilometre by 6,200 kilometre orbit, joining the Mars Reconnaissance Orbiter, the European Space Agencies’ Mars Express and the aging Mars Odyssey orbiter, which has been surveying Mars since 2001.
The window for an optimal launch to Mars using a minimal amount of fuel opens every 24 to 26 months. During the last window of opportunity in 2011, the successful Mars Curiosity rover and the ill-fated Russian mission Phobos-Grunt sought to make the trip.
This time around, MAVEN will be joined by India’s Mars Orbiter Mission, launching from the Satish Dhawan Space Center on October 21st. If successful, the Indian Space Research Organization (ISRO) will join Russia, ESA & NASA in nations that have successfully launched missions to Mars.
This window comes approximately six months before Martian opposition, which next occurs on April 8th, 2014. In 2016, ESA’s ExoMars Mars Orbiter and NASA’s InSight Lander will head to Mars. And 2018 may see the joint ESA/NASA ExoMars rover and… if we’re lucky, Dennis Tito’s proposed crewed Mars 2018 flyby.
Interestingly, MAVEN also arrives in Martian orbit just a month before the close 123,000 kilometre passage of comet C/2013 A1 Siding Spring, although as of this time, there’s no word if it will carry out any observations of the comet.
These launches will also represent the first planetary missions to depart Earth since 2011. You can follow the mission as @MAVEN2Mars on Twitter. We’ll also be attending the MAVEN Conference and Workshop this weekend in Boulder and tweeting our adventures (wi-fi willing) as @Astroguyz. We also plan on attending the November launch in person as well!
And in the end, it was perhaps for the good of all mankind that our own rule-breaking (but pithy) Mars haiku didn’t get selected:
Rider of the Martian Atmosphere
Taunting Bradbury’s golden-bee armed Martians
While dodging the Great Galactic Ghoul
Hey, never let it be said that science writers make great poets!
Do you want to go to Mars?
Well here’s your chance to get connected for a double barreled dose of Red Planet adventure courtesy of MAVEN – NASA’s next ‘Mission to Mars’ which is due to liftoff this November from the Florida Space Coast.
For a limited time only, NASA is offering the general public two cool ways to get involved and ‘Go to Mars’ aboard a DVD flying on the solar winged MAVEN (Mars Atmosphere and Volatile Evolution) orbiter.
You can send your name and a short poetic message to Mars via the ‘Going to Mars’ campaign being managed by the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics (CU/LASP).
“Anybody on planet Earth is welcome to participate!” says NASA.
“The Going to Mars campaign offers people worldwide a way to make a personal connection to space, space exploration, and science in general, and share in our excitement about the MAVEN mission,” said Stephanie Renfrow, lead for the MAVEN Education and Public Outreach program at CU/LASP.
Signing up to send your name is easy. Simply click on the MAVEN mission website – here.
Everyone who submits their name will be included on a DVD that will be attached to the winged orbiter. And you can print out a beautiful certificate of participation emblazoned with your name!
Over 1 million folks signed up to send their names to Mars with NASA’s Curiosity rover. So they are all riding along as Curiosity continues making ground breaking science discoveries and already found habitats that could support potential Martian microbes.
Writing the haiku poem will require thought, inspiration and creativity and involves a public contest – because only 3 poems will be selected and sent to Mars. The public will vote for the three winning entries.
Haiku’s are three line poems. The rules state that “the first and last lines must have exactly five syllables each and the middle line must have exactly seven syllables. All messages must be original and not plagiarized in any way.”
The complete contest rules are found at the mission website – here:
This is a simple way for kids and adults alike to participate in humanity’s exploration of the Red Planet. And it’s also a great STEM activity for educators and school kids of all ages before this year’s school season comes to a close.
“This new campaign is a great opportunity to reach the next generation of explorers and excite them about science, technology, engineering and math,” said Bruce Jakosky, MAVEN principal investigator from CU/LASP. “I look forward to sharing our science with the worldwide community as MAVEN begins to piece together what happened to the Red Planet’s atmosphere.”
MAVEN is slated to blast off atop an Atlas V rocket from Cape Canaveral Florida on Nov. 18, 2013. It will join NASA’s armada of four robotic spacecraft when it arrives at Mars during 2014.
MAVEN is the first spacecraft devoted to exploring and understanding the Martian upper atmosphere. The spacecraft will investigate how the loss of Mars’ atmosphere to space determined the history of water on the surface.
But don’t dawdle- the deadline for submissions is July 1.
So, sign up to ‘Go to Mars’ – and do it NOW!
Juice up your inner poet and post your ‘Haiku’ here – if you dare

After taking a well deserved and unavoidable break during April’s solar conjunction with Mars that blocked two way communication with Earth, NASA’s powerful Martian fleet of orbiters and rovers have reestablished contact and are alive and well and ready to Rock ‘n Roll ‘n Drill.
“Both orbiters and both rovers are in good health after conjunction,” said NASA JPL spokesman Guy Webster exclusively to Universe Today.
Curiosity’s Chief Scientist John Grotzinger confirmed to me today (May 1) that further drilling around the site of the initial John Klein outcrop bore hole is a top near term priority.
The goal is to search for the chemical ingredients of life.
“We’ll drill a second sample,” Grotzinger told Universe Today exclusively. Grotzinger, of the California Institute of Technology in Pasadena, Calif., leads NASA’s Curiosity Mars Science Laboratory mission.
“We’ll move a small bit, either with the arm or the wheels, and then drill another hole to confirm what we found in the John Klein hole.”
Earth, Mars and the Sun have been lined up in nearly a straight line for the past several weeks, which effectively blocked virtually all contact with NASA’s four pronged investigative Armada at the Red Planet.
NASA’s Red Planet fleet consists of the Curiosity (MSL) and Opportunity (MER) surface rovers as well as the long lived Mars Odyssey (MO) and Mars Reconnaissance Orbiter (MRO) robotic orbiters circling overhead. ESA’s Mars Express orbiter is also exploring the Red Planet.
“All have been in communications,” Webster told me today, May 1.
The NASA spacecraft are functioning normally and beginning to transmit the science data collected and stored in on board memory during the conjunction period when a commanding moratorium was in effect.
“Lots of data that had been stored on MRO during conjunction has been downlinked,” Webster confirmed to Universe Today.
And NASA is already transmitting and issuing new marching orders to the Martian Armada to resume their investigations into unveiling the mysteries of the Red Planet and determine whether life ever existed eons ago or today.
“New commanding, post-conjunction has been sent to both orbiters and Opportunity.”
“And the sequence is being developed today for sending to Curiosity tonight (May 1), as scheduled more than a month ago,” Webster explained.
“We’ll spend the next few sols transitioning over to new flight software that gives the rover additional capabilities,” said Grotzinger.
“After that we’ll spend some time testing out the science instruments on the B-side rover compute element – that we booted to before conjunction.”
Curiosity is at work inside the Yellowknife Bay basin just south of the Martian equator. Opportunity is exploring the rim of Endeavour crater at the Cape York rim segment.
Mars Solar Conjunction is a normal celestial event that occurs naturally about every 26 months. The science and engineering teams take painstaking preparatory efforts to insure no harm comes to the spacecraft during the conjunction period when they have no chance to assess or intervene in case problems arise.
So it’s great news and a huge relief to the large science and operations teams handling NASA’s Martian assets to learn that all is well.
Since the sun can disrupt and garble communications, mission controllers suspended transmissions and commands so as not to inadvertently create serious problems that could damage the fleet in a worst case scenario.
So what’s on tap for Curiosity and Opportunity in the near term ?
“For the first few days for Curiosity we will be installing a software upgrade.”
“For both rovers, the science teams will be making decisions about how much more to do at current locations before moving on,” Webster told me.
The Opportunity science team has said that the long lived robot has pretty much finished investigating the Cape York area at Endeavour crater where she made the fantastic discovery of phyllosilicates clay minerals that form in neutral water.
Signals from Opportunity received a few days ago on April 27 indicated that the robot had briefly entered a standby auto mode while collecting imagery of the sun.
NASA reported today that all operations with Opportunity was “back under ground control, executing a sequence of commands sent by the rover team”, had returned to normal and the robot exited the precautionary status.
“The Curiosity team has said they want to do at least one more drilling in Yellowknife Bay area,” according to Webster.
Curiosity has already accomplished her primary task and discovered a habitable zone that possesses the key ingredients needed for potential alien microbes to once have thrived in the distant past on the Red Planet when it was warmer and wetter.
The robot found widespread evidence for repeated episodes of flowing liquid water, hydrated mineral veins and phyllosilicates clay minerals on the floor of her Gale Crater landing site after analyzing the first powder ever drilled from a Martian rock.

During conjunction Curiosity collected weather, radiation and water measurements but no imagery.

Are you ready to take a fun journey? One with a little Spirit? Then don’t miss the Opportunity to take the Mars Rover out for a drive. NASA has introduced a new website release which gives you page after page of awesome slideshows and entertaining text. If you’re looking for a great way to spend a few hours – be it by yourself or with kids – then you’ve got to visit “Explore Mars: Spirit’s Journey”. Here are just a few examples of what you’ll encounter…
“My team sent me to a football-sized rock called “Adirondack.” It had very little dust covering it. It also had a smooth surface, making it easier for me to put my arm right against it.”
“It was a rocky road to Bonneville, but worth it. Craters are good to study because they show deeper layers in their walls. The deeper the layer, the older the record of what Mars was like earlier in its history.”
“Once I got to the hills, my team faced a tough challenge. No robot had ever hiked up a hill and they didn’t know how they would get me up this massive summit.”
“After almost six months since landing, finally! Signs of past water! As I hiked up the hills, I came across a knobby looking rock. My team called it “Pot of Gold,” because this rock contains a mineral called hematite.”
But this isn’t all to the pages… just a few stops! In “Explore Mars: Spirit’s Journey” you will also find a virtual journey in 3D, an “All About Mars” program, more information on the Mars Rovers and even the opportunity to become a Martian! It’s a very entertaining way to spend some time. Enjoy!
