SOLAR PROBE PLUS Update: Send Your Name Towards the Sun!

An artist's concept of NASA's Parker Solar Probe spacecraft approaching the Sun.

Send Your Name to the Sun Aboard Parker Solar Probe (Press Release)

NASA’s Parker Solar Probe — designed, built and managed by Johns Hopkins Applied Physics Laboratory (APL) — will launch in summer 2018 and travel to our star on a historic mission to “touch the Sun.” Now you can get on board and be a part of this voyage of extreme exploration.

NASA is giving everyone across the world the opportunity to submit their names for a journey to the Sun. Names will be added to a microchip that will fly aboard Parker Solar Probe as it makes its way from Earth to the Sun — the first mission to ever do so.

Along for the ride will be a revolutionary heat shield, which will protect the spacecraft from soaring temperatures as it plunges into the corona to get the first close-up view of Earth’s star.

Name submissions will be accepted until April 27, 2018. Learn more and add your name to the mission here:

Parker Solar Probe’s scientific objectives include tracing the flow of energy and understanding the heating of the solar corona, and exploring what accelerates the solar wind. It will also help scientists understand in greater detail how the Sun affects the solar system and Earth.

“Parker Solar Probe is, quite literally, the fastest, hottest — and, to me, coolest — mission under the Sun,” said project scientist Nicola Fox, of APL. “This incredible spacecraft is going to reveal so much about our star and how it works that we’ve not been able to understand.”

Originally dubbed Solar Probe Plus, the spacecraft was renamed Parker Solar Probe in May 2017, in honor of astrophysicist Eugene Parker. Parker proposed the solar wind’s existence in his now famous 1958 paper published in the Astrophysical Journal. This is the first time NASA has named a spacecraft for a living individual.

“This probe will journey to a region humanity has never explored before,” said Thomas Zurbuchen, the associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “This mission will answer questions scientists have sought to uncover for more than six decades.”

Japan's Hayabusa 2 Spacecraft Spots Its Asteroid Destination...

An animated GIF showing asteroid Ryugu moving through deep seen by JAXA's Hayabusa 2 spacecraft on February 26, 2018.An image of asteroid Ryugu that was taken by JAXA's Hayabusa 2 spacecraft on February 26, 2018.

Hayabusa 2 Has Detected Ryugu! (Press Release)

On February 26, 2018, Hayabusa 2 saw its destination—asteroid Ryugu—for the first time! The photographs were captured by the ONC-T (Optical Navigation Camera - Telescopic) onboard the spacecraft. Images were taken between noon JST on February 26th and 9:00 AM the following morning, with about 300 shots taken in total. Data for nine of these images were transmitted from the spacecraft on February 27th, allowing us to confirm that Ryugu had indeed been seen. The animation shows these nine consecutive frames.

Ryugu's brightness from Hayabusa 2 is about magnitude 9, which would be impossible to see with the naked eye but visible with the ONC-T. Looking at the image above, you can see how the position of the surrounding stars relative to Ryugu appears to change as Hayabusa 2 moves towards the asteroid. The distance between Ryugu and Hayabusa 2 when the images were taken is about 1.3 million km. Ryugu as seen from Hayabusa 2 is in the direction of the constellation Pisces.

Ryugu was photographed when the Sun, Hayabusa 2 and Ryugu were almost in a line. This configuration can be seen in the figure below, which shows a snapshot of the header from the Hayabusa 2 website on February 26, 2018, which continuously updates to show the position of Hayabusa 2. If you were to stand on Ryugu, Hayabusa 2 would be seen in the direction of the Sun.

Hayabusa 2 is currently using its ion engine to make adjustments to its course. This makes it difficult to alter the orientation of the spacecraft. However, at the alignment shown below, the ONC-T camera can image Ryugu without needing to make significant changes to the spacecraft's orientation. This made February 26th the perfect time to try and capture Ryugu's image with the ONC-T. From the data, Ryugu was observed to be exactly at the expected location based on Hayabusa 2's estimated position. This tells us that Hayabusa 2 is flying on the planned course.

"Now that we see Ryugu, the Hayabusa 2 project has shifted to the final preparation stage for arrival at the asteroid. There are no problems with the route towards Ryugu or the performance of the spacecraft, and we will be proceeding with maximum thrust," explains Project Manager, Yuichi Tsuda.

The remaining images will be transmitted back to Earth from the spacecraft and allow us to further confirm the asteroid and spacecraft location. Although we can currently see Ryugu only as a point, it is very exciting for the whole project team to catch sight of the destination! The ONC-T was developed under collaboration between JAXA, the University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, The University of Aizu, the National Institute of Advanced Industrial Science and Technology (AIST).

NASA InSight Mission to Mars Arrives at Launch Site (News Release)

NASA's InSight spacecraft has arrived at Vandenberg Air Force Base in central California to begin final preparations for a launch this May. The spacecraft was shipped from Lockheed Martin Space, Denver, today and arrived at Vandenberg at 3:49 p.m. PST (6:49 p.m. EST). The launch period for InSight opens May 5 and continues through June 8. InSight will be the first mission to look deep beneath the Martian surface, studying the planet's interior by listening for marsquakes and measuring the planet's heat output. It will also be the first planetary spacecraft to launch from the West Coast.

"The Air Force C-17 crew from the 21st Airlift Squadron gave us a great ride," said Tom Hoffman, InSight project manager, from NASA's Jet Propulsion Laboratory in Pasadena, California. "Next time InSight travels as high and as fast, it will be about 23 seconds into its launch, on the way to Mars."

At the Astrotech payload processing facility at Vandenberg, InSight will soon be removed from its shipping container -- the first of several remaining milestones to prepare it for launch. Later next week, the spacecraft will begin functional testing to verify its state of health after the flight from Colorado. After that, the team will load updated flight software and perform a series of mission readiness tests. These tests involve the entire spacecraft flight system, the associated science instruments and the ground data system.

"One of the most important activities before launch is to load the spacecraft with the fuel needed for the journey to Mars," said Hoffman. "After fuel loading, the spacecraft will undergo a spin-balance test to determine precisely the center of mass. This knowledge is needed to be sure the entry and descent into the Mars atmosphere goes as planned."

InSight will be carried into space aboard a United Launch Alliance Atlas V-401 rocket lifting off from Space Launch Complex 3E at Vandenberg Air Force Base. For a May 5 liftoff, the launch window opens at 4:05 a.m. PDT (7:05 a.m. EDT) and remains open through 6:05 a.m. PDT (9:05 a.m. EDT).

InSight will use the seismic waves generated by marsquakes to map the deep interior of Mars. These waves travel through geologic materials at different speeds and reflect off boundaries, giving scientists a glimpse of the composition and structure of the planet's interior. They reflect the initial formation of the planet, and the resulting insights into how Mars formed will help us better understand how other rocky planets are created, including our own Earth.

JPL manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. The InSight spacecraft, including cruise stage and lander, was built and tested by Lockheed Martin Space in Denver. A number of European partners, includingFrance's Centre National d'√Čtudes Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission.

Sixteen days after the opening ceremony was held inside the Pyeongchang Olympic Stadium in South Korea, the 2018 Winter Games are no more. Norway ended the tournament as the winning country with a total of 39 medals (14 gold, 14 silver and 11 bronze), while the United States finished fourth (behind Norway, Germany and Canada, respectively) with 23 medals. America garnered 9 gold, 8 silver and 6 bronze (including one by Alpine skier Lindsey Vonn, whose appearance in the PyeongChang Games may be her last in the Olympics). The Russians who weren't banned by the International Olympic Committee this year gathered 17 medals (2 gold, 6 silver and 9 bronze) under the Olympic Athletes from Russia banner.

Photo of the Day: My High School's Uniforms 54 Years Ago...

The color of the uniforms at my old high school...circa 1964.

One of my friends recently sent me this old picture that she found of our former high school back in 1964. This photo is jaw-dropping for two reasons: 1.) The colors of the uniforms are totally different from what they are today (the theme colors for our high school are now royal blue and gold). Also, it's amusing that there were uniforms back during the 1960s when my oldest brother (and I think my sister) got to wear casual clothing to class until uniforms were re-instated in the early 90s (all of my siblings—I have two brothers and one sister—and I attended this school). And 2.) The demographics of the students in this image are waaaaaay different from what they are in 2018 (and 1994 thru '98, the years that I attended this high school). How different, you ask? Well, let's just say that the neighborhoods surrounding my alma mater apparently didn't have any Asians or Latinos (mostly Latinos) living in 'em more than 50 years ago. That's how different.

And in case you didn't notice after I mentioned what years I was in high school in the previous paragraph: My 20-year high school reunion is this October! We'll see if I go. Have a happy Presidents' Day weekend.

Go Lancers!

NASA’s Transiting Exoplanet Survey Satellite Arrives at Kennedy Space Center for Launch (News Release)

NASA’s next planet-hunting mission has arrived in Florida to begin preparations for launch. The Transiting Exoplanet Survey Satellite (TESS) is scheduled to launch on a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station nearby NASA’s Kennedy Space Center in Florida no earlier than April 16, pending range approval. TESS was delivered Feb. 12 aboard a truck from Orbital ATK in Dulles, Virginia, where it spent 2017 being assembled and tested. Over the next month, the spacecraft will be prepped for launch at Kennedy’s Payload Hazardous Servicing Facility (PHSF).

TESS is the next step in NASA’s search for planets outside our solar system, known as exoplanets. The mission will scan nearly the entire sky to monitor more than 200,000 of the nearest and brightest stars in search of transit events — periodic dips in a star’s brightness caused by planets passing in front of their stars. TESS is expected to find thousands of exoplanets. The upcoming James Webb Space Telescope, scheduled for launch in 2019, will provide important follow-up observations of some of the most promising TESS-discovered exoplanets, allowing scientists to study their atmospheres and, in some special cases, to search for signs that these planets could support life.

TESS is a NASA Astrophysics Explorer mission led and operated by MIT in Cambridge, Massachusetts, and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Dr. George Ricker of MIT’s Kavli Institute for Astrophysics and Space Research serves as principal investigator for the mission. Additional partners include Orbital ATK, NASA’s Ames Research Center in California’s Silicon Valley, the Harvard-Smithsonian Center for Astrophysics and the Space Telescope Science Institute. More than a dozen universities, research institutes and observatories worldwide are participants in the mission. NASA’s Launch Services Program is responsible for launch management. SpaceX of Hawthorne, California, is the provider of the Falcon 9 launch service.

Mars 2020 Update: Bringing a Martian Rock Back to Its Planet of Origin...

A Piece of Mars is Going Home (News Release)

A chunk of Mars will soon be returning home.

A piece of a meteorite called Sayh al Uhaymir 008 (SaU008) will be carried on board NASA's Mars 2020 rover mission, now being built at the agency's Jet Propulsion Laboratory in Pasadena, California. This chunk will serve as target practice for a high-precision laser on the rover's arm.

Mars 2020's goal is ambitious: collect samples from the Red Planet's surface that a future mission could potentially return to Earth. One of the rover's many tools will be a laser designed to illuminate rock features as fine as a human hair.

That level of precision requires a calibration target to help tweak the laser's settings. Previous NASA rovers have included calibration targets as well. Depending on the instrument, the target material can include things like rock, metal or glass, and can often look like a painter's palette.

But working on this particular instrument sparked an idea among JPL scientists: why not use an actual piece of Mars? Earth has a limited supply of Martian meteorites, which scientists determined were blasted off Mars' surface millions of years ago.

These meteorites aren't as unique as the geologically diverse samples 2020 will collect. But they're still scientifically interesting -- and perfect for target practice.

"We're studying things on such a fine scale that slight misalignments, caused by changes in temperature or even the rover settling into sand, can require us to correct our aim," said Luther Beegle of JPL. Beegle is principal investigator for a laser instrument called SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals). "By studying how the instrument sees a fixed target, we can understand how it will see a piece of the Martian surface."

SHERLOC will be the first instrument on Mars to use Raman and fluorescence spectroscopies, scientific techniques familiar to forensics experts. Whenever an ultraviolet light shines over certain carbon-based chemicals, they give off the same characteristic glow that you see under a black light.

Scientists can use this glow to detect chemicals that form in the presence of life. SHERLOC will photograph the rocks it studies, then map the chemicals it detects across those images. That adds a spatial context to the layers of data Mars 2020 will collect.

"This kind of science requires texture and organic chemicals -- two things that our target meteorite will provide," said Rohit Bhartia of JPL, SHERLOC's deputy principal investigator.

No Flaky Meteorites

Martian meteorites are precious in their rarity. Only about 200 have been confirmed by The Meteoritical Society, which has a database listing these vetted meteorites.

To select the right one for SHERLOC, JPL turned to contacts at NASA's Johnson Space Center in Houston, as well as the Natural History Museum of London. Not just any Martian meteorite would do: its condition would need to be solid enough that it would not flake apart during the intensity of launch and landing.

It also needed to possess certain chemical features to test SHERLOC's sensitivity. These had to be reasonably easy to detect repeatedly for the calibration target to be useful.

Experts tried several samples, cutting off thin bits to test whether they would crumble. Using a "flaky" sample could damage the entire meteorite in the process.

The SHERLOC team ultimately agreed on using SaU008, a meteorite found in Oman in 1999. Besides being more rugged than other samples, a piece of it was available courtesy of Caroline Smith, principal curator of meteorites at London's Natural History Museum.

"Every year, we provide hundreds of meteorite specimens to scientists all over the world for study," Smith said. "This is a first for us: sending one of our samples back home for the benefit of science."

SaU008 will be the first Martian meteorite to have a fragment return to the planet's surface -- though not the first on a return trip to Mars.

NASA's Mars Global Surveyor included a chunk of a meteorite known as Zagami. It's still floating around the Red Planet onboard the now-defunct orbiter.

Additionally, the team behind Mars2020's SuperCam instrument will be adding a Martian meteorite to their own calibration target.

Preparing for Humans on Mars

Along with its own Martian meteorite, SHERLOC's calibration target will include several interesting scientific samples for human spaceflight. These include materials that could be used to make spacesuit fabric, gloves and a helmet's visor.

By watching how they hold up under Martian weather, including radiation, NASA will be able to test these materials for future Mars missions.

"The SHERLOC instrument is a valuable opportunity to prepare for human spaceflight as well as to perform fundamental scientific investigations of the Martian surface," said Marc Fries, a SHERLOC co-investigator and curator of extraterrestrial materials at Johnson Space Center. "It gives us a convenient way to test material that will keep future astronauts safe when they get to Mars."

Photos of the Day: Let the PyeongChang Games Begin!

Chang W. Lee / The New York Times

At 3 AM, PST (8 PM, Korean Time) today, the opening ceremony for the 2018 Winter Olympics was held in PyeongChang County, South Korea. Here's hoping that the Games of the 23rd Winter Olympics (they aren't referred to as an 'Olympiad'—unlike the Summer Games, which are more historical in nature) occur without a hitch over the next 2+ weeks. Kim Jong-un can resume comparing the size of his 'nuclear button' with that of Donald Trump after the closing ceremony is held on February 25. And let's cross our fingers that North and South Koreans can peacefully compete against each other over the next 14 or so days even though the Olympic venues are only 50 miles from the deadly no-man's land otherwise known as the Demilitarized Zone. If not, then don't be surprised if you see, as a show of force, U.S. Air Force B-52 bombers or F-22 (and maybe F-35) jet fighters streaking high above a snowboarding or skiing competition being televised on NBC at the time. Being a military buff, that would be an awesome sight to see. But for anyone else (particularly hippie millennial pacifists), that would be such a disconcerting visual to take in while watching a competition designed to promote goodwill among nations occur on the Korean Peninsula.

New Horizons Update: The Spacecraft Makes History in the Kuiper Belt...

Two false-color snapshots of Kuiper Belt Objects 2012 HZ84 (left) and 2012 seen by NASA's New Horizons spacecraft in December 2017.

New Horizons Captures Record-Breaking Images in the Kuiper Belt (News Release)

NASA’s New Horizons spacecraft recently turned its telescopic camera toward a field of stars, snapped an image – and made history.

The routine calibration frame of the “Wishing Well” galactic open star cluster, made by the Long Range Reconnaissance Imager (LORRI) on Dec. 5, was taken when New Horizons was 3.79 billion miles (6.12 billion kilometers, or 40.9 astronomical units) from Earth – making it, for a time, the farthest image ever made from Earth.

New Horizons was even farther from home than NASA’s Voyager 1 when it captured the famous “Pale Blue Dot” image of Earth. That picture was part of a composite of 60 images looking back at the solar system, on Feb. 14, 1990, when Voyager was 3.75 billion miles [6.06 billion kilometers, or about 40.5 astronomical units (AU)] from Earth. Voyager 1’s cameras were turned off shortly after that portrait, leaving its distance record unchallenged for more than 27 years.

LORRI broke its own record just two hours later with images of Kuiper Belt Objects 2012 HZ84 and 2012 HE85 – further demonstrating how nothing stands still when you’re covering more than 700,000 miles (1.1 million kilometers) of space each day.

Distance and Speed

New Horizons is just the fifth spacecraft to speed beyond the outer planets, so many of its activities set distance records. On Dec. 9 it carried out the most-distant course-correction maneuver ever, as the mission team guided the spacecraft toward a close encounter with a KBO named 2014 MU69 on Jan. 1, 2019. That New Year’s flight past MU69 will be the farthest planetary encounter in history, happening one billion miles beyond the Pluto system – which New Horizons famously explored in July 2015.

During its extended mission in the Kuiper Belt, which began in 2017, New Horizons is aiming to observe at least two-dozen other KBOs, dwarf planets and “Centaurs,” former KBOs in unstable orbits that cross the orbits of the giant planets. Mission scientists study the images to determine the objects’ shapes and surface properties, and to check for moons and rings. The spacecraft also is making nearly continuous measurements of the plasma, dust and neutral-gas environment along its path.

The New Horizons spacecraft is healthy and is currently in hibernation. Mission controllers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, will bring the spacecraft out of its electronic slumber on June 4 and begin a series of system checkouts and other activities to prepare New Horizons for the MU69 encounter.
