It’s a tiny satellite with ambitious goals: to zip all the way from the Earth to the Moon using a solar sail. A typical “cubesat” satellite sticks around Earth’s orbit to do a science, but the team behind Lunarsail convinced dozens of crowfunding donors that their concept can go even further.
The team asked for $11,000 on Kickstarter and actually received more than $15,000. The next step is to submit a formal proposal to NASA to hitch a ride on a rocket and get into space. (An announcement of opportunity was on NASA’s website in mid-August, but the link is currently unavailable as the agency’s site is shut down amid the government furlough. The posted deadline was Nov. 26).
“Common sense seems to suggest that cubesats don’t have the power or the huge rocket they would need to reach the Moon. Common sense can be deceptive, though,” the team wrote on their crowdfunding campaign page.
“It doesn’t take a more powerful spacecraft … the satellite doesn’t care what orbit it’s in — it just does its thing. It also doesn’t require a more powerful rocket. All we need is a rocket powerful enough to put the spacecraft into an appropriate orbit around the Earth, and then we can take over and get ourselves to the Moon.”
The Aerospace Research & Engineering Systems (ARES) Institute, which is the entity behind Lunarsail, further plans to involve students in the campaign. It’s asking around to see if there are any interested parties who could “bring mission-related science activities to thousands of students, particularly those in minority and at-risk communities.” If this goes forward, students could participate through experiments, observations and also with mobile apps.
While the team acknowledges it takes time to get a concept on a rocket and into space, they have a goal of having everything “flight-ready” by December 2016. Follow updates on the project at its web page.
We’ve got a pretty bright Moon, but that just means we’ve got another target for the Virtual Star Party.
Tonight we had beautiful views of the Moon from David Dickinson and Cory Schmitz, and then some deep sky objects from Gary Gonella and Cory. We saw Andromeda Galaxy, Bubble Nebula, Swan Nebula, Lagoon Nebula, Dumbbell Nebula. And some viewers shared their photographs, including some amazing images of the International Space Station.

Developing story – NASA’s Juno-bound Jupiter orbiter successfully blazed past Earth this afternoon (Oct. 9) and gained its huge and critical gravity assisted speed boost that’s absolutely essential to reach the Jovian system in 2016.
However, Juno’s project manager Rick Nybakken told me moments ago that the Juno spacecraft unexpectedly entered ‘safe mode’ during the fly by maneuver and the mission teams are assessing the situation.
But the very good news is “Juno is power positive at this time. And we have full command ability,” said Nybakken in an exclusive phone interview with me.
“After Juno passed the period of Earth flyby closest approach at 12:21 PM PST [3:21 PM EDT] and we established communications 25 minutes later, we were in safe mode,” Nybakken told me. Nybakken is the Juno mission project manager at NASA’s Jet Propulsion Lab in Pasadena, CA.
Furthermore, the Earth flyby did place the $1.1 Billion Juno spacecraft exactly on course for Jupiter as intended.
“We are on our way to Jupiter as planned!”
“None of this affected our trajectory or the gravity assist maneuver – which is what the Earth flyby is.”
Juno’s closest approach was over South Africa at about 500 kilometers (350 miles).
“Juno hit the target corridor within 2 km of the aim point,” Nybakken elaborated to Universe Today.
Juno needs the 16,330 mph velocity boost from the Earth swingby because the Atlas V launcher was not powerful enough to hurtle the 8000 pound (3267 kg) craft fast enough on a direct path to Jupiter.
And the team is in full radio contact with the probe. Safe mode is a designated protective state.
“Prior to the eclipse, which was a few minutes earlier than closest approach, the spacecraft was ‘nominal’. When we came out of the eclipse Juno was in safe mode,” Nybakken stated.
“We are going through safe mode diagnostics steps right now.”
“We have established full uplink and downlink. And we have full command ability of the spacecraft.”
Speed boosting slingshots have been used on numerous planetary missions in the past
The spacecraft’s power situation and health is as good as can be expected.
“Juno is power positive at this time and sun pointed and stable. So we are very pleased about that,” Nybakken explained.
I asked if Juno had ever entered ‘safe mode’ before?
“We have never been in safe mode before. We are in a safe, stable state.”
“We are investigating this,” said Nybakken.
Today’s (Oct. 9) Earth flyby is the only time the spacecraft experiences an eclipse period during Juno’s entire five year and 1.7 Billion mile (2.8 Billion km) trek to Jupiter, the largest planet in our solar system.
When it finally arrives at Jupiter on July 4, 2016, Juno will become the first polar orbiting spacecraft at the gas giant.
NASA’s Juno spacecraft blasted off atop an Atlas V rocket two years ago from Cape Canaveral Air Force Station, FL, on Aug. 5, 2011 on a journey to discover the genesis of Jupiter hidden deep inside the planet’s interior.
The science team had also hoped to use the on board JunoCam imager to make a cool and unprecedented movie of Earth as it approached from the sunlit side – showing the passage as though you were a visitor from outer space.
I had an inkling that something might be amiss this afternoon when no images of Earth appeared on the Juno mission website.
So I asked the status.
“We don’t know yet if any images of Earth were collected. We hope to know soon.”
Juno flew past the Moon before the gravity assist slingshot with Earth. And it did manage to successfully capture several lunar images. See the images herein.

Note: Due to the continuing chaos resulting from the US government partial shutdown caused by gridlocked politico’s in Washington DC, NASA public affairs remains shut down and is issuing no official announcements on virtually anything related to NASA! This pertains to Juno’s flyby, LADEE’s lunar arrival on Oct. 6, MAVEN’s upcoming launch in November, Cygnus at the ISS, and more!
Stay tuned here for continuing Juno, LADEE, MAVEN and more up-to-date NASA news.
For millennia, human eyes have seen only one face of the moon. Put a dude from the Iron Age in a time machine and whisk him to 2013 and he’d see the same pattern of light lunar highlands punctuated by dark grey spots you see. Night after night after night.
That all changed 54 years ago today when the Soviet Union’s Luna 3 probe opened its camera shutter and snapped the first pictures of the lunar far side. Though blurry and banded with electronic noise, everyone who saw them sat up in surprise. The backside barely resembled the front. It lacked in the familiar lunar maria, the dark spots that we instinctively patch together to form the face of the “man in the moon”.
Only two dark ovals were seen, Mare Moscoviense (Sea of Moscow) and the lava-filled floor of the crater Tsiolkovsky, named for Konstantin Tsiolkovksy, the Russian rocket pioneer. The rest, which looks like dried paste, is jammed with craters and related the near side’s light-toned, cratered highlands. Both are remnants of the original lunar crust that solidified as the moon cooled after formation.
Darker areas or “seas” are more recent basaltic lavas that welled up to fill huge impact scars left by colliding asteroids. They contain iron-rich minerals from deep beneath the crust which make them less reflective, hence darker in comparison to the highlands.
The moon hides its back or far side through a neat trick – it rotates at the same rate as it revolves around the Earth. Normally, rotation would bring new features into view, but every little bit it turns, it moves an equal amount along its orbit, hiding what would otherwise be exposed. It’s called synchronous rotation or tidal locking. Most of the larger moons in the solar system are tidally locked to their planets. Jupiter’s four biggest and brightest moons are a great example.
Equipped with both wide angle (200 mm) and telephoto (500 mm) lenses, Luna 3 took 29 pictures covering about 70 percent of the far side during its loop around the moon. The first picture was shot from 39,500 miles away (63,500 km), the last taken 40 minutes later from 41,445 miles (66,700 km) distant. After the photo session was done, the probe passed over the moon’s north pole and headed back toward Earth.
Temperature and radiation-resistant film used for the photos was automatically moved to an onboard processor where it was developed, fixed and dried. A cathode ray tube then shot a beam of light through the film and onto a photoelectric multiplier, a light-sensitive device that converted the different gradations of tone into electric signals which were then transmitted to Earth. Almost sounds like a fire brigade, but hey it worked!
So what’s the reason for the moon’s split personality? We know the far side crust is 50 miles (80 km) thick versus 37 miles (60 km) for the near side. A thicker far side crust may have prevented magma from reaching and flooding the surface as they did on the near side. Heat released by the decay of radioactive elements also may play a role. NASA’s Lunar Prospector probe found more on the near side, where they may have encouraged the formation of hot magmas that eventually found their way to the surface.
What caused the fascinating asymmetry is unknown, but it may have to do with the slowing of the moon’s rotation into its present tidally-locked state under the heavy hand of Earth’s dominating gravitational influence.
NASA’s LADEE lunar orbiter will fire its main engine on Oct. 6 to enter lunar orbit in the midst of the US government shutdown. Credit: NASA

Update Oct 6: LADEE fired its main engine this morning (Oct. 6) at 6:57 a.m. EDT and successfully achieved lunar orbit. Headline/story revised.
NASA’s trailblazing LADEE lunar spacecraft is set to ignite its main engine and enter lunar orbit on Sunday morning, Oct. 6 – if all goes well – following the spectacular Sept. 6 night launch from NASA’s Virginia spaceport.
And in a happenstance no one could have foreseen, the critical engine firing comes smack in the midst of the political chaos reigning in Washington D.C. that has shut down the US government, furloughed 97% of NASA’s employees, and temporarily threatened the upcoming launch of NASA’s next mission to Mars – the MAVEN orbiter.
But there will be virtually a complete news blackout and little public information released due to the legal requirements of the shutdown.
NASA websites, which are amongst the most heavily trafficked, as well as NASA TV have been shuttered during the shutdown and the press office is likewise furloughed.
So it was do or die for LADEE with the four minute long braking thruster firing set to start on Oct. 6 at 6:57 a.m. EDT (10:57 UTC), so that the couch sized spacecraft is captured by the Moon’s gravity.
Fortunately, LADEE was deemed “essential” and a small team of engineers is working right now at mission control at NASA’s Ames Research Center in California.
If the had burn failed, LADEE will swing by the moon with no hope of returning. And this is being accomplished with a skeleton crew thanks to the government shutdown.
Here’s a video animation of orbital capture at the moon:
Video caption: This video shows the LADEE lunar orbit capture scheduled to take place at 10:57 UTC on 6 Oct. 2013. The main view is an Earth centered perspective showing the effect of the Moon’s gravity on the orbit and then how a Lunar orbit looks from the Earth. The inset view shows the same trajectory from the perspective of the Moon.
Dubbed LOI-1 (Lunar Orbit Insertion burn 1),it is designed to begin with LADEE’s arrival at the Moon after three and a half orbits of the Earth. It will change the spacecrafts velocity by 329.8 meters/sec.
LOI-1 is the first of three main engine maneuvers and will place LADEE into a 24 hour retrograde orbit, with a periselene altitude of 590 km (369 mi).
LOI-2 follows on Oct. 9 to place LADEE into a 4 hour orbit with a 250 km (156 mi) periselene altitude.
Finally LOI-3 on Oct. 12 places LADEE into a roughly circular 250 km (156 mi) orbit that initiates a 30 day commissioning phase as well as experiments using the on-board Lunar Laser Communications Experiment (LLCD) before the start of the missions science phase.
LADEE thundered to space atop the maiden launch of the five stage Minotaur V rocket on Sept. 6, blazing a spectacular trail to orbit from a beachside launch pad at NASA’s Wallops Flight Facility in Virginia.
The blastoff was easily visible to tens of millions of thrilled spectators up and down the eastern seaboard stretching from Maine to the Carolinas as a result of crystal clear skies and the night time liftoff.
The LADEE liftoff at 11:27 p.m. EDT marked the first space probe of any kind ever launched beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission ever launched from Wallops.
Eventually the spacecraft will fly in a very low equatorial science orbit of about 50 kilometers (31 mi) altitude above the moon that will require considerable fuel to maintain. The science mission duration is approximately 100 days, limited by the amount of maneuvering fuel.
The 844 pound (383 kg) robot explorer was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.
It is equipped with a trio of science instruments whose purpose is to collect data that will inform scientists in unprecedented detail about the ultra thin lunar atmosphere, environmental influences on lunar dust and conditions near the surface.
The goal of the $280 Million mission is to gain a thorough understanding of long-standing unknowns about the tenuous atmosphere, dust and surface interactions that will help scientists understand other planetary bodies as well.
The probe is built on a revolutionary ‘modular common spacecraft bus’, or body, that could dramatically cut the cost of exploring space and also be utilized on space probes to explore a wide variety of inviting targets in the solar system.
“LADEE is the first in a new class of interplanetary exploration missions,” NASA Ames Director Pete Worden told Universe Today in an interview. “It will study the pristine moon to study significant questions.”
“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”
Ever since (and most likely long before) the first tantalizing glimpses of a lunar lava tube and skylight were captured by Japan’s Kaguya spacecraft in 2009, scientists have been dreaming of ways to explore inside these geological treasures. Not only would they provide valuable information on the movement of ancient lunar lava flows, but they could also be great places for future human explorers to set up camp and be well-protected from dangerous solar and cosmic radiation.
But before human eyes will ever peer into the darkness of a lava tube on the Moon, robotic rovers will roll along their silent floors — at least, they will if Google Lunar XPRIZE competitor Astrobotic has anything to say about it.
Last month, engineer and Astrobotic CEO Dr. Red Whitttaker talked to NASA about why they want to explore a Moon cave and the history and progress of their project. Check it out below:
“Something so unique about the lava tubes is that they are the one destination that combines the trifecta of science, exploration, and resources.”
– Dr. William “Red” Whittaker, CEO Astrobotic Technology, Inc.
The international Google Lunar XPRIZE aims to create a new “Apollo” moment for a new generation by driving continuous lunar exploration with $40 million in incentive-based prizes. In order to win, a private company must land safely on the surface of the Moon, travel 500 meters above, below, or on the lunar surface, and send back two “Mooncasts” to Earth… all by Dec. 31, 2015.
Astrobotic Technology Inc. is a Pittsburgh-based company that delivers affordable space robotics technology and planetary missions. Spun out of Carnegie Mellon University’s Robotics Institute in 2008, Astrobotic is pioneering affordable planetary access that promises to spark a new era of exploration, science, tourism, resource utilization and mining.

Did you notice a bright “star” close to the Moon last night (September 8, 2013)? People around the world had the treat of seeing the waxing crescent Moon have the planet Venus snuggle up close… or in some places, the Moon actually passed in front of Venus, in what is known as an occultation. Also, on Saturday, the bright star Spica added to the scene.
Thanks to our readers from around the world for sharing their images and videos!
Here’s a video showing the occultation of Venus by the Moon, photographed by Fabian Gonzalez.

WALLOPS ISLAND, VA – A NASA moon probe named LADEE thundered to space tonight, Sept. 6, blazing a spectacular trail to orbit from a beachside launch pad in Virginia that was easily visible to tens of millions of spectators along the eastern seaboard as a result of crystal clear skies and the night time liftoff – see magnificent photo shot from NYC above by Ben Cooper/Launchphotography.com.
The drama at the LADEE launch site on the eastern shore of Virginia at NASA’s Wallops Island facility was palpable due to the historic and experimental nature of the mission.
Hordes of tourists flooded into Virginia to be eyewitnesses to an unprecedented space spectacle that marked Americas ‘Return to the Moon’ and a chance to see the type of big and exciting rocket launches previously reserved for Florida and California.
Everyone I spoke too was absolutely overwhelmed with the amazing beauty of the Minotaur V blastoff carrying LADEE to orbit, whooping and hollering, far beyond our wildest expectations as the crackling fire pierced through the night and reverberated in our ears!
“It was a picture perfect launch,” said NASA Associate Administrator John Grunsfeld at a post launch media briefing at NASA Wallops.
“LADEE will help us unravel the mysteries of the lunar atmosphere.”
Blastoff of NASA’s dust exploring Lunar Atmosphere and Dust Environment Explorer (LADEE) Observatory marked the first space probe of any kind ever launched beyond Earth orbit from NASA Wallops, as well as being the first planetary science mission from Wallops.
The Minotaur V rocket launched precisely on time at 11:27 p.m. EDT on the maiden flight of the powerful new Minotaur V rocket Launch Pad 0B on NASA’s Wallops Flight Facility.
“The spacecraft is healthy and power positive and separated from the fifth and last stage on time, approximately 23 minutes into the flight,” said Pete Worden to Universe Today after the liftoff. Worden is the Director of NASA’s Ames Research Center which designed and built LADEE using a revolutionary new design to reduce costs and increase science output.
The liftoff of LADEE (pronounced ‘laddie’ not ‘lady’) also marks the first launch of a five stage rocket and the first launch of a decommissioned Peacekeeper missile from Wallops. The Peacekeeper was a nuclear armed intercontinental ballistic missile ICBM built during the Cold War – now retired and refurbished by Orbital for peaceful uses.
The Minotaur V fifth stage boosted LADEE into a highly elliptical orbit. Over about the next 23 days, as LADEE orbits Earth 3.5 times, the Moon’s gravitational field will increase the apogee of its orbit. The spacecraft will fire its on-board braking thrusters to achieve lunar orbit.
The mission will fly in a very low science orbit of about 50 kilometers altitude above the moon that will require considerable fuel to maintain. The science mission duration is approximately 100 days.
The 844 pound (383 kg) robot explorer is the size of a couch and was assembled at NASA’s Ames Research Center, Moffett Field, Calif., and is a cooperative project with NASA Goddard Spaceflight Center in Maryland.

“This is probably our last best chance to study the pristine Moon before there is a lot of human activity there changing things.”
The five stage Minotaur V rocket stands 80.6 feet (24.6 meters) tall, is 7.6 feet (2.3 m) in diameter and weighs 197,034 pounds (89,373 kilograms).
The first three stages of the Minotaur V are based on the nuclear armed Peacekeeper ICBM intercontinental ballistic missile built during the Cold War – now retired and refurbished by Orbital Sciences for peaceful uses.
The upper 5th stage is a new addition and what makes this Minotaur a new rocket class. The additional thrust is what converts the Minotaur V into an interplanetary booster that enables shooting for the Moon.
“I dreamed all my life about launching a rocket to the moon. And now we are doing it,” Lou Amorosi, told Universe Today at the Minotuar launch pad. Amorosi is the Senior Vice President of Orbital’s Small Space Launch Vehicle business.
“This mission further demonstrates the capabilities of our well-established Minotaur rocket family and our commitment to providing reliable access to space,” Amorosi noted in a post launch statement.

NASA’s heading back to the Moon, and you can see the launch – either live with your own eyes if you live on the US Eastern Seaboard, or online here or on NASA TV. The mission is LADEE, the Lunar Atmosphere and Dust Environment Explorer. As of this writing, the spacecraft sits atop a Minotaur V rocket on Wallops Island, Virginia. Launch is scheduled for 11:27 p.m. EDT on September 6 (0327 UTC Sept. 7). If you live in a swath long the US East Coast that stretches from Naine to North Carolina, check out our detailed information here of how you can see the nighttime launch for yourself, weather permitting.
If you want to watch online, we’ve got NASA’s UStream feed below, and all the online action starts Friday night at 9:30 p.m. EDT (0130 GMT, early Saturday.
Of course, if you have NASA TV on your cable or satellite lineup, you can watch on your television. Another option is that The Planetary Society is also have a live show starting an hour before launch at their website. Also the NASA EDGE team also will have a webcast.
Sky watchers worldwide are in for a treat Sunday evening September 8, 2013 as the waxing crescent Moon passes near the dazzling planet Venus. And for a select few, the Moon will actually pass in front of Venus, in what is known as an occultation.
The action has already started this week, as the Moon reached New phase earlier today at 7:36 AM EDT/11:36 UT. The appearance of the slim crescent Moon nearest to the September equinox marks the start of the Jewish New Year with the celebration of Rosh Hashanah, which this year began as early as it possibly can at sundown on September 4th. As per tradition, Rosh Hashanah formally begins when the sky is dark enough for three stars to be seen. The convention established by Hillel II in 363 A.D. uses the mean motion of the Moon to fix the start dates of the Jewish luni-solar calendar, which means that occasionally Rosh Hashanah can start a day early. This also occurred in 2002.
The New Moon has also been historically an opportune time for nighttime military operations to commence —Desert Storm in 1991 and the raid against Bin Laden in 2011 were both conducted under the darkness afforded by the absence of moonlight around a New Moon. It’s yet to be seen if planners looking to conduct airstrikes on Syria are planning on taking advantage of the same conditions to begin operations soon.
Tonight, you can see the +1st magnitude star Spica less than two degrees away from -4th magnitude Venus. This places Venus at 100 times brighter than Spica and visible before sunset if you know exactly where to look for it.
The brightest star in the constellation Virgo, Spica is 260 light years distant and on the short list of nearby stars that will eventually go supernova. Fortunately for us, Spica is well outside of the ~100 light year radius “kill zone”.
You might just be able to spy the Moon and the -1st magnitude planet Mercury low to the west at dusk for the first time for this lunation tonight or (more likely) Friday night. This is also a great time to check out LADEE’s future home as it departs for lunar orbit from Wallops Island in Virginia on Friday night.
Hey, LADEE sitting on the pad atop its Minotaur V rocket with the slim crescent Moon in the background at dusk Friday night would be a great money shot, I’m just sayin’…
This weekend will see the Moon increase in illumination and elevation above the western horizon each evening until Spica, Venus, and the waxing crescent Moon fit within a four degree circle on Sunday night. The Moon will be 12% illuminated, while Venus is currently at a gibbous phase and 72% lit.
This will also present a good chance to see Venus during the daytime, using the nearby crescent Moon as a guide. This is a fun thing to try, and no gear is required! Though Venus may seem tough to find against the bright daytime sky, appearances are deceptive. With an albedo of 67% versus the Moon’s average of 14% Venus is actually brighter than the Moon per square arc second of size!
The Moon will also occult Spica on the evening of September 8th for observers in the Middle East and Europe right around sunset. Spica is one of four bright stars that the Moon can occult in the current epoch, along with Antares, Aldebaran, and Regulus. This is also part of a series of fine occultations of Spica by the Moon ongoing from 2012 to 2014.
Sundown on September 8th offers a special treat, as the 3-day old Moon passes less than a degree from Venus worldwide. The pair will fit easily into the field of view of binoculars or a telescope at low power and present an outstanding photo op.
And for observers based in Argentina and Chile, the Moon will actually occult Venus. Occultations are grand events, a split-second astronomical event in a universe that seems to usually move at a glacial pace. This particular occultation occurs for South American observers just before & after sunset.
We witnessed and recorded a similar pairing of Venus and the daytime Moon from the shores of our camp on Saint Froid Lake in northern Maine back in 2007:
Also, keep an eye out for a ghostly phenomenon known as the ashen light on the dark limb of the Moon. Also known as Earthshine, what you’re seeing is the reflection of sunlight off of the Earth illuminating the (cue Pink Floyd) dark side of the Moon. When the Moon is a crescent as seen from the Earth, the Earth is at gibbous phase as seen from the nearside of the Moon. Remember, the lunar farside and darkside are two different things! Earthshine can vary in brightness, based on the amount of cloud and snow cover present or absent on the Earth’s moonward side. My Farmer’s Almanac-consulting grandpappy would call ashen light the “Old Moon in the New Moon’s arms,” and reckon rain was a comin’…
Be sure to check out these astronomical goings on this weekend, and send those pics in to Universe Today!
