ESO: ALMA & ROSETTA find keys to the mysteries of phosphorus, a building block of life

A new report from the European Southern Observatory (ESO):

Astronomers Reveal Interstellar Thread of One of Life’s Building Blocks

This infographic shows the key results from a study that has revealed the interstellar thread of phosphorus, one of life’s building blocks.  Thanks to ALMA, astronomers could pinpoint where phosphorus-bearing molecules form in star-forming regions like AFGL 5142. The background of this infographic shows a part of the night sky in the constellation of Auriga, where the star-forming region AFGL 5142 is located. The ALMA image of this object is on the top left of the infographic, and one of the locations where the team found phosphorus-bearing molecules is indicated by a circle. The most common phosphorus-bearing molecule in AFGL 5142 is phosphorus monoxide, represented in orange and red in the diagram on the bottom left. Another molecule found was phosphorus nitride, represented in orange and blue.  Using data from the ROSINA instrument onboard ESA’s Rosetta, astronomers also found phosphorus monoxide on comet 67P/Churyumov–Gerasimenko, shown on the bottom right. This first sighting of phosphorus monoxide on a comet helps astronomers draw a connection between star-forming regions, where the molecule is created, all the way to Earth, where it played a crucial role in starting life.

Phosphorus, present in our DNA and cell membranes, is an essential element for life as we know it. But how it arrived on the early Earth is something of a mystery. Astronomers have now traced the journey of phosphorus from star-forming regions to comets using the combined powers of ALMA and the European Space Agency’s probe Rosetta. Their research shows, for the first time, where molecules containing phosphorus form, how this element is carried in comets, and how a particular molecule may have played a crucial role in starting life on our planet.

Life appeared on Earth about 4 billion years ago, but we still do not know the processes that made it possible,

says Víctor Rivilla, the lead author of a new study published today in the journal Monthly Notices of the Royal Astronomical Society. The new results from the Atacama Large Millimeter/Submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, and from the ROSINA instrument on board Rosetta, show that phosphorus monoxide is a key piece in the origin-of-life puzzle.

With the power of ALMA, which allowed a detailed look into the star-forming region AFGL 5142, astronomers could pinpoint where phosphorus-bearing molecules, like phosphorus monoxide, form. New stars and planetary systems arise in cloud-like regions of gas and dust in between stars, making these interstellar clouds the ideal places to start the search for life’s building blocks.

The ALMA observations showed that phosphorus-bearing molecules are created as massive stars are formed. Flows of gas from young massive stars open up cavities in interstellar clouds. Molecules containing phosphorus form on the cavity walls, through the combined action of shocks and radiation from the infant star. The astronomers have also shown that phosphorus monoxide is the most abundant phosphorus-bearing molecule in the cavity walls.

This ALMA image shows a detailed view of the star-forming region AFGL 5142. A bright, massive star in its infancy is visible at the centre of the image. The flows of gas from this star have opened up a cavity in the region, and it is in the walls of this cavity (shown in colour), that phosphorus-bearing molecules like phosphorus monoxide are formed. The different colours represent material moving at different speeds.

After searching for this molecule in star-forming regions with ALMA, the European team moved on to a Solar System object: the now-famous comet 67P/Churyumov–Gerasimenko. The idea was to follow the trail of these phosphorus-bearing compounds. If the cavity walls collapse to form a star, particularly a less-massive one like the Sun, phosphorus monoxide can freeze out and get trapped in the icy dust grains that remain around the new star. Even before the star is fully formed, those dust grains come together to form pebbles, rocks and ultimately comets, which become transporters of phosphorus monoxide.

ROSINA, which stands for Rosetta Orbiter Spectrometer for Ion and Neutral Analysis, collected data from 67P for two years as Rosetta orbited the comet. Astronomers had found hints of phosphorus in the ROSINA data before, but they did not know what molecule had carried it there. Kathrin Altwegg, the Principal Investigator for Rosina and an author in the new study, got a clue about what this molecule could be after being approached at a conference by an astronomer studying star-forming regions with ALMA:

She said that phosphorus monoxide would be a very likely candidate, so I went back to our data and there it was!

This first sighting of phosphorus monoxide on a comet helps astronomers draw a connection between star-forming regions, where the molecule is created, all the way to Earth.

The combination of the ALMA and ROSINA data has revealed a sort of chemical thread during the whole process of star formation, in which phosphorus monoxide plays the dominant role,

says Rivilla, who is a researcher at the Arcetri Astrophysical Observatory of INAF, Italy’s National Institute for Astrophysics.

Phosphorus is essential for life as we know it,” adds Altwegg. “As comets most probably delivered large amounts of organic compounds to the Earth, the phosphorus monoxide found in comet 67P may strengthen the link between comets and life on Earth.”

This intriguing journey could be documented because of the collaborative efforts between astronomers.

The detection of phosphorus monoxide was clearly thanks to an interdisciplinary exchange between telescopes on Earth and instruments in space,”

says Altwegg.

Leonardo Testi, ESO astronomer and ALMA European Operations Manager, concludes:

Understanding our cosmic origins, including how common the chemical conditions favourable for the emergence of life are, is a major topic of modern astrophysics. While ESO and ALMA focus on the observations of molecules in distant young planetary systems, the direct exploration of the chemical inventory within our Solar System is made possible by ESA missions, like Rosetta. The synergy between world leading ground-based and space facilities, through the collaboration between ESO and ESA, is a powerful asset for European researchers and enables transformational discoveries like the one reported in this paper.

** Arianespace heads for a busy year in 2020 with multiple types of rockets lifting off from Kourou, Kazakhstan, and Russia: Arianespace could launch record 22 missions in 2020 – SpaceNews.com

Half of the European launch provider’s 2020 manifest is comprised of OneWeb launches — 10 Soyuz missions and the inaugural launch of the Ariane 62 rocket. 

Arianespace also has two launches scheduled for its smallest rocket, Vega, and two for the larger next-generation Vega C, Stéphane Israël, Arianespace’s chief executive, said in a Jan. 7 interview.

Of the 22 missions, 14 are planned from Europe’s spaceport, the Guiana Space Center, on the coast of South America, Israël said. The remaining eight are Soyuz missions the company expects will be split about even between Russia’s spaceports, the Baikonur Cosmodrome in Kazakhstan, and the Vostochny Cosmodrome in Russia’s Far East, near China, he said. 

Arianespace’s record is 12 launches in one year, set in 2015.

** Sierra Nevada gives an update on development of Dream Chaser cargo and crew variants:Dream Chaser on Track for 2021 Cargo Mission, Crew Within 5 Years – SpacePolicyOnline.com

Sierra Nevada Corporation (SNC) is on track for the first cargo flight of its Dream Chaser spacecraft next year.  Looking like a small space shuttle, Dream Chaser lost out on a contract for NASA’s commercial crew program, but was selected in the second round of commercial cargo contracts.  SNC still plans to use Dream Chaser for crewed missions for other customers and expects the first within 5 years.  SNC also is bidding on contracts for NASA’s Artemis program, including as part of a Dynetics team for the Human Landing System.

Steve Lindsey, a former NASA astronaut who is now SNC’s Senior Vice President of Strategy for Space Systems, and other SNC officials gave updates on Dream Chaser and other space activities during a media telecon today.

SNC has “never stopped working” on the crewed version of Dream Chaser, Lindsey said. While the company’s focus right now is getting the cargo version ready for its first flight on a United Launch Alliance (ULA) Vulcan-Centaur rocket next year, the first crewed flight “absolutely” will take place within 5 years.

** ABL Space Systems to use Air Force facilities to test components for the RS1 launch vehicle for smallsat orbital deliveries: Small launch startup ABL Space Systems to test rocket hardware at Edwards Air Force Base – SpaceNews.com

Based in El Segundo, California, ABL was founded by former SpaceX engineers in 2017 to develop low-cost launch vehicles for the small satellite industry. The company’s RS1 vehicle was designed to lift 1,200 kilograms into low Earth orbit at a price of $12 million per launch.

ABL announced on July 22 — just days after signing the cooperative agreement with AFRL — that Lockheed Martin Ventures would become an investor in the company.

Nils Sedano, technical adviser on rocket propulsion systems at AFRL, told SpaceNews Jan. 9 that ABL has “come in and established their presence at area 1-56 of the AFRL rocket propulsion division.”

AFRL is the primary rocket propulsion scientific research and development center for the U.S. Air Force.

** An update from the Planetary Society on LightSail-2, which launched last summer on a SpaceX Falcon Heavy:

High above Earth, The Planetary Society’s LightSail 2 spacecraft is still sailing on sunbeams. During the 5 months since LightSail 2 deployed its solar sail on 23 July 2019, the spacecraft has continued to demonstrate the first controlled solar-sailing flight in Earth orbit. 

The LightSail 2 team is releasing a paper today that describes new results from the mission. Purdue University’s Justin Mansell is also presenting the results at the 30th Space Flight Mechanics Meeting in Orlando, Florida. The paper recaps mission events through late November, discusses the performance of the solar sail and attitude control system, and describes how the spacecraft’s orbit has changed. 

LightSail 2 flies at a higher altitude than most satellites in low-Earth orbit. While the International Space Station orbits Earth at an altitude of about 400 kilometers, LightSail 2 orbits at about 720 kilometers. Since fewer spacecraft orbit at LightSail 2’s altitude, there wasn’t enough data on Earth’s atmospheric density to reliably predict how much atmospheric drag would slow down the spacecraft. We now know for certain that the atmosphere at 720 kilometers is dense enough to overcome the thrust imparted by solar sailing.

LightSail 2 near the Middle East: LightSail 2 captured this image of the Gulf of Oman and the Persian Gulf on 14 December 2019. The sail appears slightly curved due to the spacecraft’s 185-degree fisheye camera lens. The image has been color corrected and some of the distortion has been removed.” Credits: Planetary Society

** Secretive Astra Space aims for three launches from Alaskan spaceport this year: FCC Filing Confirms Final Contestant in DARPA’s $12 Million Satellite Launch Challenge – IEEE Spectrum.

Astra Space (previously named Ventions) is developing a small payload orbital launch system and is competing in the DARPA Launch Challenge, which requires a demonstration of a quick response (30 days) to a request for the launch of a smallsat. While the company refuses to answer press queries, applications for launch and communications licenses provides some info on what they are doing:

The company carried out two suborbital launches from PSCA in 2019 but the rockets appeared to have problems shortly after liftoff. According to the FAA license, this year Astra will attempt three orbital flights from Pacific Spaceport Complex – Alaska (PSCA) on Kodiak Island. They may also do a flight from the commercial launch facility at Wallops Island but a separate FAA license will be required.
