Cassini: ave atque vale

Saturn. Image: nssdc.gsfc.nasa.gov/

Over the course of ‘goodbye kisses’ with moon Titan, Cassini circled deeper and deeper into Saturn‘s atmosphere until, in a fiery immolation, the spacecraft became part of the planet. A collaborative macroengineering project by Nasa (National Aeronautics and Space Administration), Jet Propulsion Laboratory (California Institute of Technology), Esa (European Space Agency) and Asi (Italian Space Agency), Cassini-Huygens launched on 15 October 1997, explored areas including Venus, Jupiter, and Asteroid 2685 Masursky, before falling into attraction with Saturn, entering the planet’s orbit on 1 July 2004 never to return. Dancing through the rings, the spacecraft sent back data that will continue to live on for many years after Cassini merged with Saturn on 15 September 2017. Cassini-Huygens was named after Giovanni Domenico Cassini, discoverer of Saturn’s rings; and Christiaan Huygens, discoverer of Titan.

21 billion kilometer record

 

“Sounds of Earth” Golden Record, launched in 1977, plays on. Take a listen. Image: nasa.gov.

It’s a shiny gold record compiled by a team headed by Carl Sagan, honored with the NASA Apollo Achievement Award. And it’s also just set a record, as the farthest human-made object from earth. Sending our best in sound from Bach and Beethoven (String Quartet 13) to Solomon Islands’ Panpipes, from the haunting whistle of a train to the coo of a baby and the sound of a kiss, the record contains an homage to our planet. “Sounds of the Earth” also includes greetings in 55 languages including cetic (whale). “Sounds of the Earth” was launched in 1977, on two Voyager space probes. And now, along with space residents who may be receiving the message, you can hear it, too.

Eclipses and Innovations

Solar Eclipse: Image: NASA, 2016.

The Great American Eclipse, 21 August 2017, may lead to innovations. Thomas Edison is said to have invented the incandescent light bulb after witnessing a total eclipse in Wyoming, USA in 1878. Just the year before, at the age of 30, Edison had invented the phonograph. Friends engaged Edison’s scientific and technical curiosity with word of an impending celestial wonder; a train ride to Rawlins, Wyoming ensued. The town was tiny: there was only one hotel and only one room left; Thomas Edison, Henry Draper, and the whole expedition bunked there and waited. The night before the eclipse, Edison recalled reclining outdoors and staring at the star-lit sky; suddenly the idea for a light bulb appeared. Perhaps Edison was also influenced by recent demonstrations of Pavel Nikolayevich Yablochkov’s arc lighting at the Paris Exposition Universelle of 1878. A few years later, Gustav Eiffel would open the Paris International Exposition of 1889 with the Eiffel Tower.

Yablochkov’s arc lamps were used by early movie studios for indoor scenes, but produced so much ultra-violet light that actors had to wear sunglasses. Even more protective are the special glasses viewers must don to view the Great American Eclipse of 2017. MIT’s Haystack Observatory will study the eclipse effects on space weather with radar and navigational satellites. Nasa and scientists worldwide will study the space phenomenon from every place on earth, and above. Eyes on the sky: what inventions and innovations may result?

Space Agent Wanted: Apply Here

“Buzz Aldrin Walks On Moon.” Image: wikimedia commons.

Just two more weeks to apply for an out-of-this-world job: Nasa is seeking a “planetary protection officer.” Think public health on a galactic level. Spacecraft land on planets, but they rarely take their shoes off upon returning home. Similarly, as humans set foot on lunar and other surfaces, what might they carry  on those moon boots that will forever contaminate new worlds?

In 1967, the United Nations Outer Space Treaty stipulated that nations take heed of contamination, but the law applied only to countries; at the time, COMSAT was just forming, nor were private space enterprises such as Blue Origin, Virgin Galactic, Planetary Resources, Inc, and SpaceX yet anticipated.

“The Day the Earth Smiled.” On 19 July, 2013, Cassini slipped behind Saturn for this photo. Image: NASA/JPL-Caltech/SSI

Nasa is so careful about contamination, according to current PPO Dr. Catharine Conley, the agency learned a lesson on 21 September 2003 when Galileo, first spacecraft to visit an asteroid (two, actually: Isa and Gaspra), observer of Venus, explorer of Jupiter, where it discovered the saltwater ocean on Europa and volcanic activity on Io, and a magnetic field on Ganymede, plummeted into Jupiter’s atmosphere rather than crash into Europa. It is there one might find life. Cassini, currently orbiting Saturn, will be similarly decommissioned.

If you become the successful applicant for HQ17S0010, as PPO it may be your responsibility to update the Outer Space Treaty? What will you do to protect interplanetary public health?

Eye on the Sky

Jupiter’s “Red Eye in the Sky” image by citizen scientist Jason Major using data from the Juno NASA mission. Image credit: NASA/JPL-Caltech/SWRI/MSSS/Jason Major. Nasa.gov.

Juno met Jupiter this week. NASA‘s Juno mission flew over the planet’s 10,000-mile-wide (16,000 kilometers) storm, so big that three earths could fit inside of the Great Red Spot. Since 1830, sky-watchers have kept an eye on this mysterious spot marking a storm that has raged for eons. When the Juno mission launched in 2011, the spacecraft did not arrive in orbit around Jupiter until July 4, 2016. Since then, it’s been photographing Jupiter, and will continue operations until 2018. Knowledge gained by Juno may serve useful in updating the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space that entered into force in 1967. Principles include:

“Exploration of space for the benefit of all countries and all humankind;

Outer space not subject to national appropriation or occupation;

Outer space to be free of nuclear or other weapons of mass destruction;

Countries and states shall be liable for damage caused by their space objects;

The Moon and other celestial bodies shall be used exclusively for peaceful purposes.”

At the start of the Space Race, only governments were thought to be financially and technologically capable of Space missions. But now private enterprise has taken impressive steps; Weinzierl and Acocella recently introduced a Harvard Business School case on the ownership of space with a close up of Jeff Bezos and Blue Origin. Planetary Resources, Inc, SpaceX, Virgin Galactic are also prominent, joined now by an enterprise hoping to win Google’s $20million Lunar X Prize, Moon Express.

COMSAT might be an organizational model to follow. On 31 August, 1962 the Communications Satellite Act became law and set a new tone of inclusiveness that transformed the space race with greater multinational, public/private cooperation. New agreements about the future of space may foretell a mixed-economy organization to promote world-wide distribution of solar power.

Bloom in the Plume

Cassini found bloom in the plume. Image:: Enceladus, nasa. gov.

At a cocktail party, someone whispered while toasting the launch of the International Geophysical Year. News spread quickly that another launch had just occurred. Sputnik may have been the spike in the punch; Apollo soon countered. Fast forward to Comsat, the international space station, spacex, and beyond. Cassini spacecraft flew through of plume of Saturn’s moon Enceladus, finding evidence of hydrothermal processes that “favor the formation of methane from CO2 in the ocean of Enceladus.” How should the Outer Space Treaty reflect such new discoveries?

It’s Earth Day: Look Up!

Ra, Egyptian sun god. Artist: Jeff Dahl. Image: wikimedia commons.

Earth Day. Could the answer to our planet’s energy problems and resultant climate change be found by looking up? Every culture on earth has myths about the sun. For example, Egypt worshipped Ra, the sun god whose falcon head was crowned with a solar disk. In 1973, building upon the success of COMSAT and the Apollo Moon Landing, Peter Glaser was awarded the United States patent for solar power from space, via satellite. Honored in the spring, as the sky glows with a stronger light, Earth Day might call us to look up.

Of Course I Still Love You

Saturn V launches Apollo 11. Image: NASA, Marshall Image Exchange.

For the first time in history, a rocket has been reused successfully. SpaceX has been practicing round-trip rocketry for years: Falcon 9 launchers have flown to/fro 13 times, with 8 perfecting the touchdown. That meant 8 rockets sitting in inventory. But never had a launch rocket yet been reused. “It’s been 15 years to get to this point,” stated Elon Musk, founder of SpaceX and Tesla, who now prices reused rockets at a discount. Packaging and discounts are a sign of private industry in space, a step beyond NASA or ESA, the European Space Agency. But reuse means more than discount: Luxembourg’s SES used the occasion to launch a communications satellite, descendant of COMSAT, to convey an environmental message. SpaceX sent a message too: in the spirit of whimsy, Falcon 9 landed on a welcoming vessel – an autonomous ship – named: “Of Course I Still Love You.”

Watcher of the Skies

TRAPPIST-1, impression by ESO/M. Kornmesser/N. Risinger. Image: wikimedia.

The first known system of seven Earth-sized planets clustered around a single star, much like our solar system, has been discovered. It’s name? TRAPPIST-1, a salute to spotting telescope in Chile. Three of the exo-planets (nomenclature indicating an orbit around a star, not a sun) are in what NASA terms the ‘habitable zone.’ All seven possess potential for water. On March 13, 1781, Sir William Herschel announced a new planet, the first discovered by telescope. Keats included Uranus in this poem:

Much have I travell’d in the realms of gold,
And many goodly states and kingdoms seen;
Round many western islands have I been,
Which bards in fealty to Apollo hold.
Oft of one wide expanse had I been told
That deep-brow’d Homer ruled as his demesne;
Yet did I never breathe its pure serene
Till I heard Chapman speak out loud and bold:
Then felt I like some watcher of the skies,
When a new planet swims into his ken;
Or like stout Cortez when with eagle eyes
He star’d at the Pacific – and all his men
Look’d at each other with a wild surmise –
Silent, upon a peak in Darien.

– John Keats, “On First Looking into Chapman’s Homer”
