The Top 101 Astronomical Events to Watch for in 2015

Phew! It’s here.

Now in its seventh year of compilation and the second year running on Universe Today, we’re proud to feature our list of astronomical happenings for the coming year. Print it, bookmark it, hang it on your fridge or observatory wall. Not only is this the yearly article that we jokingly refer to as the “blog post it takes us six months to write,” but we like to think of it as unique, a mix of the mandatory, the predictable and the bizarre. It’s not a 10 ten listicle, and not a full-fledged almanac, but something in between.

A rundown of astronomy for 2015: There’s lots of astronomical action to look forward to in the coming year. 2015 features the minimum number of eclipses that can occur, two lunars and two solars. The Moon also reaches its minimum standstill this coming year, as its orbit runs shallow relative to the celestial equator. The Moon will also occult all naked eye planets except Saturn in 2015, and will occult the bright star Aldebaran 13 times — once during every lunation in 2015. And speaking of Saturn, the rings of the distant planet are tilted an average of 24 degrees and opening to our line of sight in 2015 as they head towards their widest in 2018.

Finally, solar activity is trending downwards in 2015 after passing the sputtering 2014 maximum for solar cycle #24 as we now head towards a solar minimum around 2020.

Our best bets: Don’t miss these fine celestial spectacles coming to a sky near YOU next year:

– The two final total lunar eclipses in the ongoing tetrad, one on April 4^th and September 28^th.

– The only total solar eclipse of 2015 on March 20th, crossing the high Arctic.

– A fine dusk pairing of the bright planets Jupiter and Venus on July 1^st.

– Possible wildcard outbursts from the Alpha Monocerotid and Taurid meteors, and a favorable New Moon near the peak of the August Perseids.

– Possible naked eye appearances by comet Q2 Lovejoy opening 2015 and comet US10 Catalina later in the year.

– The occultation of a naked eye star for Miami by an asteroid on September 3^rd.

– A series of fine occultations by the Moon of bright star Aldebaran worldwide.

The rules: The comprehensive list that follows has been lovingly distilled down to the top 101 astronomical events for 2015 worldwide. Some, such as lunar eclipses, are visible to a wide swath of humanity, while others, such as many of the asteroid occultations or the sole total solar eclipse of 2015 happen over remote locales. We whittled the list down to a “Top 101” using the following criterion:

Meteor showers: Must have a predicted ZHR greater than 10.

Conjunctions: Must be closer than one degree.

Asteroid occultations: Must have a probability ranking better than 90 and occult a star brighter than magnitude +8.

Comets: Must reach a predicted brightness greater than magnitude +10. But remember: comets don’t always read prognostications such as this, and may over or under perform at whim… and the next big one could come by at any time!

Times quoted are geocentric unless otherwise noted, and are quoted in Universal Time in a 24- hour clock format.

These events are meant to merely whet the appetite. Expect ‘em to be expounded on fully by Universe Today as they approach. We linked to the events listed where possible, and provided a handy list of resources that we routinely consult at the end of the article.

Got it? Good… then without further fanfare, here’s the top 101 astronomical events for 2015 in chronological order:

Walk Beside China’s Moon Rover In Best Chang’e-3 Mission Pictures Ever

It’s been just over a year since China wowed the world with the first soft Moon landing in almost 40 years. The Chang’e-3 robotic lander made it all the way to Mare Imbrium (Sea of Rains) on Dec. 14, 2013, quickly deploying the Yutu rover for a spin.

Mission updates have been sparse in recent months, but the Planetary Society and a forum on Unmanned Spaceflight recently pointed out a new image archive. These pictures are so high-definition, it’s almost as good as being on the Moon beside the rover.

While some of the images are familiar to followers of the mission, what makes the image archive stick out is how high-definition many of them are.

A few great shots have been sent back from the surface, including a set from January that was combined into a 360-degree panorama by Marco Di Lorenzo and Universe Today’s Ken Kremer. But this archive contains a wealth of them.

The lander/rover team made it to the surface last year equipped with high-definition video cameras, prepared to catch some of the first new views of the lunar surface from close up since the Apollo robotic/human and Soviet robotic moon landing era of the 1960s and 1970s.

While Chinese officials reportedly said the rover would last three months and the lander a year, difficulties quickly cropped up.

Shortly before Yutu entered a planned hibernation for its second lunar night (about two weeks on Earth) in January, a technical problem was reported that was later identified as a problem with its solar panel.

A “control circuit malfunction”, according to the Xinhua news agency, left the rover at risk of not waking up after that second hibernation. The mast it controlled was supposed to lower and protect some of the rover’s sensitive electronics. Yutu survived the night, but was left unable to move through the third lunar day.

According to the Planetary Society (based on Chinese news media reports), there are no current status updates for Yutu, but Chang’e-3 is still working a year after the landing.

NASA’s First Orion Crew Module Arrives Safely Back at Kennedy Space Center

KENNEDY SPACE CENTER, FL – After a history making journey of more than 66,000 miles through space, ocean splash down and over 2700 mile cross country journey through the back woods of America, NASA’s pathfinding Orion crew capsule has returned to its home base at the Kennedy Space Center in Florida.

“The Orion mission was a spectacular success,” said Jules Schneider, Lockheed Martin Program manager for Orion at KSC, during a homecoming event attended by space journalists including Universe Today on Friday, Dec. 19, 2014.

“We achieved 85 of 87 test objectives,” noted Schneider. “Only an up righting air bag did not deploy fully after splashdown. And we are looking into that. Otherwise the mission went extremely well.”

Orion’s early homecoming was unexpected and a pleasant surprise since it hadn’t been expected until next week just prior to Christmas.

Orion flew on its two orbit, 4.5 hour flight maiden test flight on the Exploration Flight Test-1 (EFT-1) mission that started NASA’s long road to send astronauts beyond Earth and eventually to Mars in the 2030s.

The media were able to see the entire Orion capsule from top to bottom, including the exposed, blackened and heat scorched heat shield which had to protect the vehicle from fiery reentry temperatures exceeding 4000 F (2200 C).

Orion is being stored for now inside the Launch Abort System Facility (LASF)

“The heat shield worked extremely well and did its job,” Schneider told Universe Today.

Engineers took three samples from the 16.5 foot diameter heat shield and they are in for analysis.

“I don’t know if you can tell, we’ve actually taken a few core samples off the heat shield already and we’re looking at those,” said Schneider. “We will be removing the heat shield from this vehicle later in February so we will get an ever better look at it.”

One of the main objectives was to test the heat shield during the high speed atmospheric plummet of about 20000 mph (32000 kph) that reached approximately 85% of what astronauts will experience during a return from future voyages to Mars and Asteroids in the next decade and beyond.

“All of Orion’s system performed very well,” Schneider told me in an interview beside Orion.

“And the capsule used only about 90 pounds of its about 300 pounds of hydrazine propellant stored on board.”

“All of the separation events went beautifully and basically required virtually no maneuvering fuel to control the attitude of the capsule. The expected usage was perhaps about 150 pounds.”

“Therefore there is a lot more hydrazine fuel on board than we expected. And we had to be cautious in transporting Orion across the country.”

Lockheed Martin is the Orion prime contractor.

The Orion arrived module arrived back at KSC, Thursday afternoon after being hauled across our country mostly on back country roads, and with no publicity or fanfare, on an unmarked flat bed truck to minimize interaction with the public.

“It was like a black ops operation,” said one of the team members responsible to safely transporting Orion from Naval Base San Diego to KSC.

NASA obtained special permits to move Orion from all the states travelled between California and Florida.

“We didn’t want any publicity because the capsule was still loaded with residual toxic chemicals like ammonia and hydrazine.” These were used to power and fuel the capsule.”

Orion’s test flight began with a flawless launch on Dec. 5 as it roared to orbit atop the fiery fury of a 242 foot tall United Launch Alliance Delta IV Heavy rocket – the world’s most powerful booster – at 7:05 a.m. EST from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

The unpiloted test flight of Orion on the EFT-1 mission ignited NASA’s roadmap to send Humans to Mars by the 2030s by carrying the capsule farther away from Earth than any spacecraft designed for astronauts has traveled in more than four decades.

Humans have not ventured beyond low Earth orbit since the launch of Apollo 17 on NASA’s final moon landing mission on Dec. 7, 1972.

Watch for more details and photos later.

XPRIZE Moon Robot Contest Deadline Pushed Back A Year To 2016

For the 18 teams racing to put a robot on the Moon, some good news — they have an extra year to get the job done. Citing the groups’ difficulty in technology and raising money, the Google Lunar XPRIZE competition said the teams will now have until Dec. 31, 2016 to accomplish their missions.

The challenge was first announced in 2007 and the number of teams has stayed fairly steady since at least 2010, when 21 teams were reported in a Universe Today story. Some of the groups are competing for milestone prizes, the latest of which will be announced Jan. 15.

Astrobiotic won two previous competitions for $500,000 (in mobility) and $250,000 (for imaging). The grand prize is still open to everybody, regardless if they choose to pursue the milestone prizes.

“We know the mission we are asking teams to accomplish is extremely difficult and unprecedented, not only from a technological standpoint, but also in terms of the financial considerations,” stated Robert Weiss, XPRIZE’s vice-chairman and president.

“It is for this reason that we have decided to extend the competition timeline. We firmly believe that a whole new economy around low-cost access to the Moon will be the result of the Google Lunar XPRIZE.”

While the deadline has been extended, the goal is the same: the winning team must ferry a robotic machine to the Moon, move 500 meters (1,640 feet) somehow (on, above or below the surface) and send two “mooncasts” back to Earth. In 2013, Weiss told Universe Today that some of the teams had signed launch contracts, but declined to provide many details due to confidentiality concerns.

You can see more details about the teams and their progress on the XPRIZE website. The grand prize is $20 million and there is an additional $10 million available in other prizes.

Robotic Moon Lander Concept Raises $942K, Meeting Goal With A Day To Go

Update, Dec. 18, 8:09 a.m. EST: Lunar Mission One closed its fundraising mission the night before at £672,447 ($1,052,413), short of its stretch goal of £700,000.

With just over a day to go in their crowdfunding campaign, a British group hoping to put a robotic lander on the moon in 2024 reached their fundraising goal of $932,000 (£600,000) overnight.

The money is supposed to move the project into more concrete phases after the founders spent seven years quietly developing their concept, but many of the details about the design and funding have yet to be unveiled.

“We plan to send an unmanned robotic landing module to the South Pole of the Moon – an area unexplored by previous missions,” the mission says on its Kickstarter page. “We’re going to use pioneering technology to drill down to a depth of at least 20m – 10 times deeper than has ever been drilled before – and potentially as deep as 100m.

“By doing this,” the statement adds, “we will access lunar rock dating back up to 4.5 billion years to discover the geological composition of the Moon, the ancient relationship it shares with our planet and the effects of asteroid bombardment. Ultimately, the project will improve scientific understanding of the early Solar System, the formation of our planet and the Moon, and the conditions that initiated life on Earth.”

“Stretch goals” for the organization include rewards for backers such as an e-commerce program, a massive open online course for educational purposes, a party for backers in London, and being “a leading role” in World Space Week 2015. The additional money, however, will also be used for drilling studies, putting together the science team and making a work plan.

With the money raised, the project now has the ambitious target of getting their lander on the moon by 2024. According to the schedule, the main mission contract should be awarded by 2017, design and development begins by 2018, and the final build commences in 2021.

RAL Space (which assisted with the Philae comet landing and 200 other space missions, according to the page) is serving as a technical advisor to the board. The project chair of Lunar Missions Ltd. (which is responsible for the project) is Ian Taylor, a former United Kingdom government science minister and co-chair of the parliamentary space committee.

As with other private ventures in space such as Mars One, however, Lunar Mission One is dealing with long timelines, a risky goal and a not-certain guarantee of success.

How NASA Filmed Humans Last Leaving The Moon, 42 Years Ago

Still of the Apollo 17 spacecraft leaving the moon on Dec. 14, 1972. Credit: NASA/YouTube (screenshot)

When Apollo 17 lifted off from the moon, a camera captured the movements of the spacecraft — even though nobody was left behind to, say, establish a lunar base. How was that possible? With a camera on the lunar rover that could be controlled — or even programmed — from Earth.

Pretty impressive technology for the takeoff 42 years ago yesterday (Dec. 14) in 1972, although it took three tries to get the technique right.

As the Smithsonian National Air and Space Museum explains in a 2011 blog post, the camera was available on Apollos 15, 16 and 17. The television camera communicated from Earth using a high-gain antenna on the rover, but there was a slight time delay for the radio waves to travel (a couple of seconds) between the Earth and the Moon.

So the engineers suggested moving the rover a certain distance from the lunar module and setting the camera to automatically tilt to show the lunar liftoff when commanded from Earth.

That was the plan, at least. On Apollo 15, the tilt mechanism malfunctioned and the camera never moved upwards, allowing the lunar module to slip out of sight. And while the attempt on Apollo 16 gave a longer view of the lunar module rising up, the astronauts actually parked the rover too close to it, which threw off the calculations and timing of the tilt upwards so it left view just a few moments into the flight.

Ed Fendall was the person doing the controlling. In an oral history for NASA done in 2000, he recalled how complex the procedure was.

Now, the way that worked was this. Harley Weyer, who worked for me, sat down and figured what the trajectory would be and where the lunar rover would be each second as it moved out, and what your settings would go to. That picture you see was taken without looking at it [the liftoff] at all. There was no watching it and doing anything with that picture. As the crew counted down, that’s a [Apollo] 17 picture you see, as [Eugene] Cernan counted down and he knew he had to park in the right place because I was going to kill him, he didn’t — and Gene and I are good friends, he’ll tell you that — I actually sent the first command at liftoff minus three seconds. And each command was scripted, and all I was doing was looking at a clock, sending commands. I was not looking at the television. I really didn’t see it until it was over with and played back. Those were just pre-set commands that were just punched out via time. That’s the way it was followed.

Relive the final moments of the first test flight of NASA’s Orion spacecraft on Dec. 5, 2014, through this amazing series of up close videos showing the spacecraft plummeting back to Earth through the rollicking ocean recovery by dive teams from the US Navy and the USS Anchorage amphibious ship.

The two orbit, 4.5 hour flight maiden test flight of Orion on the Exploration Flight Test-1 (EFT-1) mission was a complete success.

It was brought back to land to the US Naval Base San Diego, California.

Humans have not ventured beyond low Earth orbit since the launch of Apollo 17 on NASA’s final moon landing mission on Dec. 7, 1972.

The spacecraft was loaded with over 1200 sensors to collect critical performance data from numerous systems throughout the mission for evaluation by engineers.

EFT-1 tested the rocket, second stage, and jettison mechanisms as well as avionics, attitude control, computers, environmental controls, and electronic systems inside the Orion spacecraft and ocean recovery operations.

It also tested the effects of intense radiation by traveling twice through the Van Allen radiation belt.

After successfully accomplishing all its orbital flight test objectives, the capsule fired its thrusters and began the rapid fire 10 minute plummet back to Earth.

During the high speed atmospheric reentry, it approached speeds of 20,000 mph (32,000 kph), approximating 85% of the reentry velocity for astronauts returning from voyages to the Red Planet.

The capsule endured scorching temperatures near 4,000 degrees Fahrenheit in a critical and successful test of the 16.5-foot-wide heat shield and thermal protection tiles.

The entire system of reentry hardware, commands, and 11 drogue and main parachutes performed flawlessly.

Finally, Orion descended on a trio of massive red and white main parachutes to achieve a statistical bulls-eye splashdown in the Pacific Ocean, 600 miles southwest of San Diego, at 11:29 a.m. EST.

It splashed down within one mile of the touchdown spot predicted by mission controllers after returning from an altitude of over 3600 miles above Earth.

The three main parachutes slowed Orion to about 17 mph (27 kph).

Here’s a magnificent up close and personal view direct from the US Navy teams that recovered Orion on Dec. 5, 2014.

Navy teams in Zodiac boats had attached a collar and winch line to Orion at sea and then safely towed it into the flooded well deck of the USS Anchorage and positioned it over rubber “speed bumps.”

Next they secured Orion inside its recovery cradle and transported it back to US Naval Base San Diego where it was off-loaded from the USS Anchorage.

The Orion EFT-1 spacecraft was recovered by a combined team from NASA, the U.S. Navy, and Orion prime contractor Lockheed Martin.

Orion has been offloaded from the USS Anchorage and moved about a mile to the “Mole Pier” where Lockheed Martin technicians have conducted the first test inspection of the crew module and collected test data.

It will soon be hauled on a flatbed truck across the US for a nearly two week trip back to Kennedy where it will arrive just in time for the Christmas holidays.

Humans Last Landed On The Moon 42 Years Ago Today

For a brief period in the 1960s and 1970s, 12 people ventured all the way to the surface of the Moon. The accomplishment at the time was hailed as a political victory over the Soviet Union, but as decades have passed the landings have taken on more symbolic meaning with NASA — a time of optimism, of science and of the American spirit.

The last lunar landing was Apollo 17, which took place on Dec. 11, 1972. Commander Eugene Cernan and lunar module pilot Harrison Schmitt did three moonwalks in the Taurus-Littrow valley, scoping out the highlands to try to get a geologic sense of the area. Among their more memorable findings are orange soil. You can see some pictures from their sojourn below.

Crazy Space Christmases: Moon Readings, Food Cans And Emergency Repairs

"AstroButch [Butch Wilmore] has set up our Xmas tree in the lab and hung socks for us," tweeted astronaut Samantha Cristoforetti from the International Space Station Dec. 7, 2014. Credit: Samantha Cristoforetti/Twitter

If you think the upside-down Christmas tree above is bizarre — that’s one of the latest activities of Expedition 42 astronauts in space right now — think back to the history of other holidays in orbit.

We’ve seen a vital telescope undergo repairs, an emergency replacement of part of a space station’s cooling system, and even a tree made of food cans. Learn more about these fun holiday times below.

Reading from above the moon (Apollo 8, 1969)

In this famous reading from the Bible, astronauts Frank Borman, Jim Lovell and Bill Anders shared their experience looking at the Moon on Dec. 24, 1968. The Apollo 8 crew was the first to venture to lunar orbit, just seven months before the Apollo 11 crew made it all the way to the surface.

Living on the Skylab station taught astronauts the value of improvisation, such as when the first crew (under NASA’s instructions) repaired a sunshield to stop electronics and people from roasting inside. Skylab 4 took the creativity to Christmas when they created a tree out of food cans.

When the Hubble Space Telescope was in hibernation due to a failed gyroscope, the STS-103 crew made repairs in December 1999 that culminated with the final spacewalk on Christmas Day. The telescope remains in great shape to this day, following another repair mission in 2009.

First Christmas on the International Space Station (Expedition 1, 2000)

The Expedition 1 crew was the first on the International Space Station to spend Christmas in orbit. “On this night, we would like to share with all-our good fortune on this space adventure; our wonder and excitement as we gaze on the Earth’s splendor; and our strong sense — that the human spirit to do, to explore, to discover — has no limit,” the crew said in a statement on Christmas Eve, in part.

Ammonia tank replacement (Expedition 38, 2013)

Just last year, an ammonia tank failure crippled a bunch of systems on the International Space Station and forced spacewalkers outside to fix the problem, in the middle of a leaky suit investigation. The astronauts made the final repairs ahead of schedule, on Christmas Eve.

While space explorers often set their sights far out in the Solar System — or even beyond — we can’t forget the majesty of our next-door neighbor. The Moon, a mere three days’ flight away from Earth during the Apollo years, is an easy beacon in the darkness for anybody to observe. Even without a telescope.

Lately, several Universe Today readers have contributed awesome shots to our Flickr pool showing some close-ups of this barren world. Take the panorama above by Roger Hutchinson, for example, showing the view along the terminator (darkness-light line). And we’ve collected some more stunners below.
