Venus is definitely not a friendly planet for humanity. Soviet landers that arrived on the surface a few decades back were crushed pretty quickly. Its surface temperature is more than 842 degrees Fahrenheit (450 degrees Celsius) and the atmosphere is full of noxious gases.
But descending into this pressure-filled cooker is exactly what Venus Express is going to do shortly. The European Space Agency spacecraft will conclude eight years of orbital operations with an attempt to fall into the planet. The maneuvers are complicated, and there’s no guarantee they will go as planned, but ESA plans to make the plunge by the end of this year.
For the better part of a decade, Venus Express has been orbiting the planet every 24 hours, swinging in an elliptical orbit that ranges from 155 miles (250 kilometers ) to 41,010 miles (66,000 kilometers). But now the spacecraft is almost out of fuel, and will now be redirected for “experimental aerobreaking” to slow down through skimming the atmosphere.
The maneuvers will take place between June 18 and July 17, where controllers hope to gain some information about the planet’s magnetic field, solar wind, temperature and pressure.
“The campaign also provides the opportunity to develop and practice the critical operations techniques required for aerobraking, an experience that will be precious for the preparation of future planetary missions that may require it operationally,” stated Paolo Ferri, head of mission operations.
No one is sure if the spacecraft will run out of fuel, or even if it survives, but if it does its orbit could be raised to do a few more scientific observations of the planet before going into the atmosphere forever.
Venus’ Express scientific treasure trove includes measuring hydrogen atom escape in the atmosphere, checking out the planet’s clouds and tracking the slowing rotation of the planet (which is happening for reasons that are not quite clear.) It also discovered an ozone layer on the planet.

Wow! This image shows the target comet for the Rosetta mission starting to develop a tail. This bodes well for the European Space Agency spacecraft, which is on its way to study Comet 67P/Churyumov–Gerasimenko later this year to learn more about the origins of the solar system.
“It’s beginning to look like a real comet,” stated Holger Sierks, principal investigator for OSIRIS (Optical, Spectroscopic and Infrared Remote Imaging System.)
“It’s hard to believe that only a few months from now, Rosetta will be deep inside this cloud of dust and en route to the origin of the comet’s activity,” added Sierks, who is with the Max Planck Institute for Solar System Research in Germany.
The picture was one of a series taken over six weeks, between March 27 and May 4, as the spacecraft zoomed to within 1.24 million miles (two million kilometers) of the target. You can see the full animation by clicking on the image below.

The comet is now about four times as far from the Sun as the Earth is. Even from afar, the Sun’s heat is warming the comet’s ice, causing dust and vapor to carry out into space — forming the coma. The coma will develop into a long tail when the comet gets even closer to the sun.
Rosetta will be the comet’s companion as it draws closer to the sun; its closest approach will be in August 2015, when it is between the orbits of Earth and Mars. So far, the spacecraft’s 11 instruments appear to be in excellent health, ESA stated, although the agency is remaining cautious as the rendezvous date approaches. The spacecraft will begin orbital insertion activities later this month, and send out its Philae lander in November.
“We have a challenging three months ahead of us as we navigate closer to the comet, but after a 10-year journey it’s great to be able to say that our spacecraft is ready to conduct unique science at comet 67P/C-G,” stated Fred Jansen, ESA’s Rosetta mission manager.

Story updated[/caption]
NASA GODDARD SPACE FLIGHT CENTER, MD – NASA’s upcoming 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. They were unveiled to greet NASA Administrator Charles Bolden on Monday, May 12, in a rare fully stacked arrangement inside the Goddard cleanroom.
Universe Today was on hand with NASA Administrator Bolden, Science Mission Chief John Grunsfeld and the MMS mission team at Goddard for a first hand inspection and up close look at the 20 foot tall, four spacecraft stacked configuration in the cleanroom and for briefings about the projects fundamental science goals.
“I’m visiting with the MMS team today to find out the status of this mission scheduled to fly early in 2015. It’s one of many projects here at Goddard,” NASA Administrator Bolden told me in an exclusive one-on-one interview at the MMS cleanroom.
“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. MMS will study what effects that process … and how the magnetosphere protects Earth.”
Magnetic reconnection is the process whereby magnetic fields around Earth connect and disconnect while explosively releasing vast amounts of energy.

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 four identical spacecraft – which are still undergoing testing – were stacked in a rarely seen launch arrangement known affectionately as the “IHOP configuration” – because they look rather like a stack of luscious pancakes.
“MMS is a fundamental heliophysics science mission,” Craig Tooley told me at the MMS cleanroom. Tooley is MMS project manager at NASA Goddard.
“Unlike Hubble that uses remote sensing, MMS is like a flying laboratory ‘in situ’ that will capture events that are the major energy transfer from the sun’s magnetic field into our Earth’s space weather environment and magnetosphere.”
“These are called magnetic reconnection events that pump enormous amounts of energy into the plasma and the fields around Earth. It’s one of the main drivers of space weather and a fundamental physical process that is not very well understood,” Tooley explained.
“The spacecraft were built in-house here at Goddard and just completed vibration testing.”
MMS will launch atop an Atlas V rocket in March 2015 from Space launch Complex 41, Cape Canaveral Air Force Station, Florida.

The vibration testing is a major milestone and is conducted to ensure the spacecraft can withstand the most extreme vibration and dynamic loads they will experience and which occurs during liftoff inside the fairing of the Atlas V booster.
MMS is also another highly valuable NASA science mission (along with MAVEN, LADEE and others) which suffered launch delays and increased costs as a result of the US government shutdown last October 2013, Bolden confirmed to Universe Today.
“We ended up slipping beyond the original October 2014 date due to the government shutdown and [the team] being out of work for a couple of weeks. MMS is now scheduled to launch in March 2015,” Bolden told me.
“So then you are at the mercy of the launch provider.”
“The downside to slipping that far is that’s its [MMS] costing more to launch,” Bolden stated.
Each of the Earth orbiting spacecraft is outfitted with 25 science sensors to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence.
Magnetic reconnection occurs throughout our universe.
“The primary mission will last two years,” Tooley told me.
“Each spacecraft carries about 400 kilograms of fuel. There is a possibility to extend the mission by about a year based on fuel consumption.”

The spacecraft will use the Earth itself as a laboratory to unlock the mysteries of magnetic reconnection – the primary process that transfers energy from the solar wind into Earth’s magnetosphere and is responsible for geomagnetic storms.
“To understand the fundamental physics, they will fly in a pyramid-like formation and capture the magnetic reconnection events in 3-D by flying through them as they happen – that’s why we have 4 spacecraft,” Tooley explained.
“Initially they will be spaced apart by about 10 to 30 kilometers while they fly in a tetrahedron formation and scan with their booms spread out – depending on what the scientists says is the optimal configuration.”
“They fly in a highly elliptical orbit between about 7,000 and 75,000 kilometers altitude during the first half of the mission. Eventually the orbit will be extended out to about 150,000 kilometers.”
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.

Story updated[/caption]
Moscow delivered a double whammy of bad news to a broad range of US space efforts today by banning the use of Russian made rocket engines for US military national security launches and by declining to prolong cooperation on the International Space Station (ISS) – says Russia’s deputy prime minister, Dmitry Rogozin, who is in charge of space and defense industries.
Rogozin was quoted in a story prominently featured today, May 13, on the English language website of Russia Today, a Russian TV news and cultural network.
“Moscow is banning Washington from using Russian-made rocket engines, which the US has used to deliver its military satellites into orbit,” said Rogozin according to the Russia Today report.
Virtually every aspect of the manned and unmanned US space program – including NASA, other government agencies, private aerospace company’s and crucial US national security payloads – are highly dependent on Russian & Ukrainian rocketry and are clearly at risk amidst the current Ukrainian crisis as tensions continue to escalate with deadly new clashes reported today in Ukraine – with global repercussions.
The engines at issue are the Russian made RD-180 engines – which power the first stage of the venerable Atlas V rocket built by United Launch Alliance (ULA) and are used to launch a wide array of US government satellites including top secret US military spy satellites for the US National Reconnaissance Office, like NROL-67, as well as science satellites for NASA like the Curiosity Mars rover and MAVEN Mars orbiter.
The dual nozzle RD-180 engines are manufactured in Russia by NPO Energomash. Rogozin’s statement effectively blocks their export to the US.

“We proceed from the fact that without guarantees that our engines are used for non-military spacecraft launches only, we won’t be able to supply them to the US,” Rogozin said.
So although the launch of NASA science missions might preliminarily appear to be exempt, they could still be at serious risk based on a qualifier from Rogozin, pertaining to RD-180 engines already delivered.
“If such guarantees aren’t provided the Russian side will also be unable to perform routine maintenance for the engines, which have been previously delivered to the US, he added.
A ULA spokesperson told me that the company has a two year supply of RD-180 engines already stockpiled in the US.
Rogozin’s statements today are clearly in retaliation to stiffened economic sanctions imposed by the US and Western nations in response to Russia’s actions in the ongoing crisis in Ukraine and the annexation of Crimea; as I reported earlier here, here and here.
Therefore, US National Security spy satellite and NASA science launches are left lingering with uncertainty and potential disarray.
Rogozin is specifically named on the US economic sanctions target list.
He was also named by SpaceX CEO Elon Musk in his firms attempt to block the importation of the RD-180 engines by ULA for the Atlas V as a violation of US sanctions.
Federal Judge Susan Braden initially imposed a temporary injunction blocking the RD-180 imports on April 30. She rescinded that order last Thursday, May 8, after receiving written communications clarifications from the US Justice and Commerce departments that the engine import did not violate the US government imposed sanctions.
Rogozin went on to say that “Moscow also isn’t planning to agree to the US offer of prolonging operation of the International Space Station (ISS) [to 2024].
“We currently project that we’ll require the ISS until 2020,” he said. “We need to understand how much profit we’re making by using the station, calculate all the expenses and depending on the results decide what to do next.”
“A completely new concept for further space exploration is currently being developed by the relevant Russian agencies”.
NASA announced early this year the agency’s intention to extend ISS operations to at least 2024, and is seeking agreement from all the ISS partners including Russia.
Since the shutdown of the Space Shuttle program in 2011 before a replacement crew vehicle was available, American astronauts are now 100% dependent on the Russian Soyuz capsule for rides to the ISS and back.
Congress has also repeatedly slashed NASA’s commercial crew program budget, forcing at least an 18 month delay in its start up and thus continued reliance on the Soyuz for years to come at over $70 million per seat.
NASA thus has NO immediate alternatives to Russia’s Soyuz – period.
The Atlas V is also planned as the launcher for two of the three companies vying for the next round of commercial crew contracts aimed at launching US astronauts to the ISS. The commercial crew contracts will be awarded by NASA later this year.
In a previous statement regarding the US sanctions against Russia, Rogozin said that sanctions could “boomerang” against the US space program and that perhaps NASA should “deliver their astronauts to the International Space Station using a trampoline.”

“One of the main things we’re focused on is the notion of existential risk, getting a sense of what the probability of human extinction is,” said Andrew Snyder-Beattie, who recently wrote a piece on the “Great Filter” for Ars Technica.

It’s time to come home! Expedition 39 astronauts Rick Mastracchio, Koichi Wakata and Mikhail Tyurin will climb into a Russian Soyuz spacecraft later today to make the trip back to Earth from the International Space Station. Much of the activity will play out on NASA TV, which you can watch above. Below are details about when to watch.
These are the descriptions from NASA about when the major events of the day occur. Bear in mind that all of these times are subject to change as circumstances warrant.
3 p.m. EDT / 7 p.m. UTC — Farewells and hatch closure (hatch closure scheduled at 3:15 p.m. / 7:15 p.m. UTC )
6:15 p.m. EDT / 10:15 p.m. UTC — Undocking (undocking scheduled at 6:33 p.m. / 10:33 p.m. UTC)
8:45 p.m. EDT / 12:45 a.m. UTC — Deorbit burn and landing (deorbit burn scheduled at 9:03 p.m. EDT /1:03 a.m. UTC landing scheduled at 9:57 p.m. EDT / 1:57 a.m. UTC)
The crew is expected to land near Dzhezkazgan in Kazakhstan. After doing some quick medical checks on site, the crew will be flown out separately to do more detailed testing at their local medical centers.
With Wakata flying home, the station is now under the command of Expedition 40 NASA astronaut Steve Swanson, who will oversee activities there along with Alexander Skvortsov and Oleg Artemyev. The rest of the Expedition 40 crew should fly to station May 28, if all goes to plan.

After one turn around the sun, it’s time for Chris Hadfield’s ultimate space music video to go to that great graveyard in the sky.
The astronaut tweeted earlier today (May 13) that singer David Bowie gave permission for Hadfield’s “Space Oddity” to be online for a year, and that the video is coming down today. So be sure to watch on YouTube above while you have the chance.
Update (6/25/14):A clarification on this story. The Ottawa Citizen newspaper clarified that it wasn’t David Bowie that only gave a year’s use of the song: “Space Oddity was the only one of more than 300 songs he has written and recorded for which he did not own or control the copyright. Mr. Bowie offered to have his people call the publisher and convey his strong support, but he had no ability to personally dictate any of the terms of the license or even require the publishers to issue one.”
Hadfield also tweeted today that ” Our Oddity will be back online soon.” We’ll repost it when it becomes available.
The Canadian’s homage to Bowie — with slightly altered lyrics — garnered more than 22.4 million views as of this morning, Eastern time. It was filmed on board the International Space Station and produced by Hadfield’s son, Evan. Music was recorded on Earth.
The video capped five months of intense public outreach that Hadfield did during Expedition 34/35 in 2012-13. During Expedition 35, he was the first Canadian commander on station, but still found time to record videos and music showcasing his time in space.
Since returning to Earth, Hadfield has already penned one best-selling book — An Astronaut’s Guide To Life On Earth — and is now working on a second that will include photos from his mission.

Here’s a finding to give planetary protectionists pause: two species of spores mounted on the International Space Station’s hull a few years back showed a high survival rate after 18 months in space.
Providing that they are shielded against solar radiation, it appears the spores are quite hardy and could easily transport on a spacecraft headed for Mars — which is concerning since so many scientific investigations there these days are focused on habitability of Martian life (whether past or present). The experiment was published in 2012, but highlighted in a recent NASA press release about planetary protection.
The experiment was called PROTECT (an acronym of Resistance of spacecraft isolates to outer space for planetary protection purposes) and studied spores of Bacillus subtilis 168 and Bacillus pumilus SAFR-032. B. pumilus spores were found in an air lock between a “clean room” and entrance floor at NASA’s Jet Propulsion Laboratory, and in previous studies were shown to be more resistant to UV radiation and hydrogen peroxide than “wild” strains. B. subtilis is a spore that has been studied in other space environment experiments.
Samples of both spores were mounted on the EXPOSE-E facility on the space station, which provides up to two years of space exposure. The major goal of this European Space Agency experiment is to study “the origin, evolution and distribution of life in the universe,” NASA states, adding that anything mounted outside of there has to survive “cosmic radiation, vacuum, full-spectrum solar light including UV-C, freezing/thawing cycles [and] microgravity.”

The experiment found that if the spores were in areas replete with solar UV radiation, most of them were killed. If those rays were filtered out, however, the spores showed a 50 percent survival rate on both space and simulated “Mars” conditions. It is most concerning to scientists when considering a situation where spores could be hiding underneath each other during a spacecraft trip. The ones on the outside would likely die, but the ones on the inside — shielded from solar radiation — could make it there.
One key limitation in this study, however, is that only two types of spores were studied. This does present a case for doing more studies on this matter in the future, however. Space agencies are quite aware of the problem of planetary protection, as evidenced by departments such as NASA’s Office of Planetary Protection and ESA’s Planetary Protection Officer.
Spacecraft designers constantly make decisions to keep the extraterrestrial bodies we study as safe from Earth contamination as possible; one famous example was when the Galileo probe was deliberately sent into Jupiter in 2003 to protect Europa and other potentially life-bearing moons of the giant planet from possible contamination.

The rock study (led by Tuscia University’s Silvano Onofri) takes the question of the spores in a different direction, which is examining the phenomenon of “lithopanspermia” — how organisms might move between planets (say, on a meteor). Since Mars meteorites have been found on Earth, some researchers have wondered if life could have spread between our two planets. If that were to happen, the researchers cautioned, the spores would have to survive for thousands or millions of years.
The other B. pumilus paper (led by NASA’s Parag A. Vaishampayan) noted that those spores mounted outside of the space station that survived, showed higher concentrations of proteins that could be linked to resisting UV radiation.

KENNEDY SPACE CENTER, FL – Boeing expects to launch the first unmanned test flight of their commercial CST-100 manned ‘space taxi’ in “early 2017,” said Chris Ferguson, commander of NASA’s final shuttle flight in an exclusive one-on-one interview with Universe Today for an inside look at Boeing’s space efforts. Ferguson is now spearheading Boeing’s human spaceflight capsule project as director of Crew and Mission Operations.
“The first unmanned orbital test flight is planned in January 2017 … and may go to the station,” Ferguson told me during a wide ranging, in depth discussion about a variety of human spaceflight topics and Boeing’s ambitious plans for their privately developed CST-100 human rated spaceship – with a little help from NASA.
Boeing has reserved a launch slot at Cape Canaveral with United Launch Alliance (ULA), but the details are not yet public.
If all goes well, the maiden CST-100 orbital test flight with humans would follow around mid-2017.
“The first manned test could happen by the end of summer 2017 with a two person crew,” he said.
Boeing is among a trio of American aerospace firms, including SpaceX and Sierra Nevada Corp, vying to restore America’s capability to fly humans to Earth orbit and the space station by late 2017, using seed money from NASA’s Commercial Crew Program (CCP) in a public/private partnership. The next round of contracts will be awarded by NASA about late summer 2014.
That’s a feat that America hasn’t accomplished in nearly three years.
“It’s been over 1000 days and counting since we landed [on STS-135],” Ferguson noted with some sadness as he checked the daily counter on his watch. He is a veteran of three space flights.

Since the shuttles retirement in July 2011 following touchdown of Space Shuttle Atlantis on the last shuttle flight (STS-135) with Ferguson in command, no American astronauts have launched to space from American soil on American rockets and spaceships.
The only ticket to the ISS and back has been aboard the Russian Soyuz capsule.
Chris and the Boeing team hope to change the situation soon. They are chomping at the bits to get Americas back into space from US soil and provide reliable and cost-effective US access to destinations in low Earth orbit like the ISS and the proposed private Bigelow space station.
Boeing wants to send its new private spaceship all the way to the space station starting on the very first unmanned and manned test flights currently slated for 2017, according to Ferguson.
“NASA wants us to provide [crew flight] services by November 2017,” said Ferguson, according to the terms of the CCP contact award.”

The CST-100 will launch atop a man rated Atlas V rocket and carry a mix of cargo and up to seven crew members to the ISS.
“So both the first unmanned and manned test flight will be in 2017. The first unmanned orbital flight test is currently set for January 2017. The first manned test could be end of summer 2017,” he stated.
I asked Chris to outline the mission plans for both flights.
“Our first flight, the CST-100 Orbital Flight Test – is scheduled to be unmanned.”
“Originally it was just going to be an on orbital test of the systems, with perhaps a close approach to the space station. But we haven’t precluded our ability to dock.
“So if our systems mature as we anticipate then we may go all the way and actually dock at station. We’re not sure yet,” he said.
So I asked whether he thinks the CST-100 will also go dock at the ISS on the first manned test flight?
“Yes. Absolutely. We want go to all the way to the space station,” Ferguson emphatically told me.
“For the 1st manned test flight, we want to dock at the space station and maybe spend a couple weeks there.”
“SpaceX did it [docking]. So we think we can too.”
“The question is can we make the owners of the space station comfortable with what we are doing. That’s what it really comes down to.”
“As the next year progresses and the design matures and it becomes more refined and we understand our own capability, and NASA understands our capabilities as the space station program gets more involved – then I’m sure they will put the same rigor into our plan as they did into the SpaceX and Orbital Sciences plans.”
“When SpaceX and Orbital [wanted to] come up for the grapple [rather than just rendezvous], NASA asked ‘Are these guys ready?’ That’s what NASA will ask us.”
“And if we [Boeing] are ready, then we’ll go dock at the station with our CST-100.”
“And if we’re not ready, then we’ll wait another flight and go to the station the next time. It’s just that simple.”
“We looked at it and this is something we can do.”
“There are a lot of ways we have to make NASA and ourselves happy. But as a company we feel we can go do it,” Ferguson stated.

So the future looks promising.
But the schedule depends entirely on NASA funding levels approved by Congress. And that vital funding has been rather short on supply. It has already caused significant delays to the start of the space taxi missions for all three companies contending for NASA’s commercial crew contracts because of the significant slashes to the agency’s CCP budget request, year after year.
In fact the schedule has slipped already 18 months to the right compared to barely a few years ago.
So I asked Chris to discuss the CCP funding cuts and resulting postponements – which significantly affected schedules for Boeing, SpaceX and Sierra Nevada.
Here it is in a nutshell.
“No Bucks, No Buck Rogers,” explained Ferguson.
“The original plan was to conduct both the unmanned and manned CST-100 test flights in 2015.”
“Originally, we would have flown the unmanned orbital test in the summer of 2015. The crewed test would have been at the end of 2015.”
“So both flights are now a full year and a half later.” Ferguson confirmed.
“For the presidents [CCP] funding requests for the past few years of roughly about $800 million, they [Congress] only approved about half. It was significantly less than the request.”
Now at this very moment Congress is deliberating NASA’s Fiscal 2015 budget.
NASA Administrator Charles Bolden has said he will beg Congress to approve full funding for the commercial crew program this year – on his hands and knees if necessary.

Otherwise there will be further delays to the start of the space taxi missions. And the direct consequence is NASA would be forced to continue buying US astronaut rides from the Russians at $70 Million per seat. All against the backdrop of Russian actions in the Ukraine where deadly clashes potentially threaten US access to the ISS in a worst case scenario if the ongoing events spin even further out of control and the West ratchets up economic sanctions against Russia.
The CST-100 is designed to be a “simple ride up to and back from space,” Ferguson emphasized to me.

It is being designed at Boeing’s Houston Product Support Center in Texas.
In Part 2 of my interview, Chris Ferguson will discuss the details about the design, how and where the CST-100 capsule will be manufactured at a newly renovated, former space shuttle facility at NASA’s Kennedy Space Center in Florida.

Are you ready for the summer of 2015? A showdown of epic proportions is in the making, as NASA’s New Horizons spacecraft is set to pass within 12,500 kilometres of Pluto — roughly a third of the distance of the ring of geosynchronous satellites orbiting the Earth — a little over a year from now on July 14th, 2015.
But another question is already being raised, one that’s assuming center stage even before we explore Pluto and its retinue of moons: will New Horizons have another target available to study for its post-Pluto encounter out in the Kuiper Belt? Researchers say time is of the essence to find it.
To be sure, it’s a big solar system out there, and it’s not that researchers haven’t been looking. New Horizons was launched from Cape Canaveral Air Force Station on January 19th, 2006 atop an Atlas V rocket flying in a 551 configuration in one of the fastest departures from Earth ever: it took New Horizons just nine hours to pass Earth’s moon after launch.

The idea has always been out there to send New Horizons onward to explore and object beyond Pluto in the Kuiper Belt, but thus far, searches for a potential target have turned up naught.
A recent joint statement from NASA’s Small Bodies and Outer Planets Assessment Groups (SBAG and OPAG) has emphasized the scientific priority needed for identifying a possible Kuiper Belt Object (KBO) for the New Horizons mission post-Pluto encounter. The assessment notes that such a chance to check out a KBO up close may only come once in our lifetimes: even though it’s currently moving at a heliocentric velocity of just under 15 kilometres a second, it will have taken New Horizons almost a decade to traverse the 32 A.U. distance to Pluto.
The report also highlights the fact that KBOs are expected to dynamically different from Pluto as well and worthy of study. The statement also notes that the window may be closing to find such a favorable target after 2014, as the upcoming observational apparition of Pluto as seen from Earth — and the direction New Horizons is headed afterwards — reaches opposition this summer on July 4th.
But time is of the essence, as it will allow researchers to plan for a burn and trajectory change for New Horizons shortly after its encounter with Pluto and Charon using what little fuel it has left. Then there’s the issue of debris in the Pluto system that may require fine-tuning its trajectory pre-encounter as well. New Horizons will begin long range operations later this year in November, switching on permanently for two years of operations pre-, during and post- encounter with Pluto.
And there currently isn’t a short-list of “next best thing” targets for New Horizons post-Pluto encounter. One object, dubbed VNH0004, may be available for distant observations in January of next year, but even this object will only pass 75 million kilometres — about 0.5 A.U. — from New Horizons at its closest.
Ground based assets such as the Keck, Subaru and Gemini observatories have been repeatedly employed in the search over the past three years. The best hopes lie with the Hubble Space Telescope, which can go deeper and spy fainter targets.
Nor could New Horizons carry out a search for new targets on its own. Its eight inch (20 cm in diameter) LORRI instrument has a limiting magnitude of about +18, which is not even close to what would be required for such a discovery.
New Horizons currently has 130 metres/sec of hydrazine fuel available to send it onwards to a possible KBO encounter, limiting its range and maneuverability into a narrow cone straight ahead of the spacecraft. This restricts the parameters for a potential encounter to 0.35 A.U. off of its nominal path for a target candidate be to still be viable objective. New Horizons will exit the Kuiper Belt at around 55 A.U. from the Sun, and will probably end its days joining the Voyager missions probing the outer solar system environment. Like Pioneers 10 and 11, Voyagers 1 and 2 and the upper stage boosters that deployed them, New Horizons will escape our solar system and orbit the Milky Way galaxy for millions of years. We recently proposed a fun thought experiment concerning just how much extraterrestrial “space junk” might be out there, littering the galactic disk.
And while the crowd-sourced Ice Hunters project generated lots of public engagement, a suitable target wasn’t found. There is talk of a follow up Ice Investigators project, though it’s still in the pending stages.
Another issue compounding the problem is the fact that Pluto is currently crossing the star rich region of the Milky Way in the constellation Sagittarius. Telescopes looking in this direction must contend with the thousands of background stars nestled towards the galactic center, making the detection of a faint moving KBO difficult. Still, if any telescope is up to the task, it’s Hubble, which just entered its 25th year of operations last month.

Shining at +14th magnitude, Pluto will be very near the 3.5th magnitude star Xi2 Sagittarii during the July 2015 encounter.
New Horizons is currently 1.5 degrees from Pluto — about 3 times the angular size of a Full Moon —as seen from our Earthly vantage point, and although neither can be seen with the naked eye, you can wave in their general direction this month on May 18th, using the nearby daytime Moon as a guide.

July 2015 will be an exciting and historic time in solar system exploration. Does Pluto have more undiscovered moons? A ring system of its own? Does it resemble Neptune’s moon Triton, or will it turn out looking entirely different ?
If nothing else, exploration of Pluto will finally give us science writers some new images to illustrate articles on the distant world, rather than recycling the half a dozen-odd photos and artist’s conceptions that are currently available. An abundance of surface features will then require naming as well. It would be great to see Pluto’s discoverer Clyde Tombaugh and Venetia Burney — the girl who named Pluto — get their due. We’ll even assume our space pundit’s hat and predict a resurgence of the “is it a planet?” debate once again in the coming year as the encounter nears…
