NASA analyzes navigation needs of Artemis Moon missions – GPS World magazine
Posted: March 31, 2021 at 6:00 am
Space communications and navigation engineers at NASA are evaluating the navigation needs for the Artemis program, including identifying the precision navigation capabilities needed to establish the first sustained presence on the lunar surface.
Artemis engages us to apply creative navigation solutions, choosing the right combination of capabilities for each mission, said Cheryl Gramling, associate chief for technology in the Mission Engineering and Systems Analysis Division at Goddard Space Flight Center in Greenbelt, Maryland. NASA has a multitude of navigation tools at its disposal, and Goddard has a half-century of experience navigating space exploration missions in lunar orbit.
Alongside proven navigation capabilities, NASA will use innovative navigation technologies during the upcoming Artemis missions.
Lunar missions provide the opportunity to test and refine novel space navigation techniques, said Ben Ashman, a navigation engineer at Goddard. The Moon is a fascinating place to explore and can serve as a proving ground that expands our navigation toolkit for more distant destinations like Mars.

Ultimately, exploration missions need a robust combination of capabilities to provide the availability, resiliency, and integrity required from an in-situ navigation system. Some of the navigation techniques being analyzed for Artemis include the following.
Radiometrics, optimetrics, and laser altimetry measure distances and velocity using the properties of electromagnetic transmissions. Engineers measure the time it takes for a transmission to reach a spacecraft and divide by the transmissions rate of travel the speed of light.
These accurate measurements have been the foundation of space navigation since the launch of the first satellite, giving an accurate and reliable measurement of the distance between the transmitter and spacecrafts receiver. Simultaneously, the rate of change in the spacecrafts velocity between the transmitter and spacecraft can be observed due to the Doppler effect.
Radiometrics and optimetrics measure the distances and velocity between a spacecraft and ground antennas or other spacecraft using their radio links and infrared optical communications links, respectively. In laser altimetry and space laser ranging, a spacecraft or ground telescope reflects lasers off the surface of a celestial body or a specially designated reflector to judge distances.
The Lunar Orbiter Laser Altimeter (LOLA) aboard the Lunar Reconnaissance Orbiter (LRO) sends laser pulses down to the surface of the Moon from the orbiting spacecraft. These pulses bounce off of the Moon and return to LRO, providing scientists with measurements of the distance from the spacecraft to the lunar surface. As LRO orbits the Moon, LOLA measures the shape of the lunar surface, which includes information about the Moons surface elevations and slopes. This image shows the slopes found near the South Pole of the Moon. (Image: NASA/LRO)
Optical navigation techniques rely on images from cameras on a spacecraft. There are three main branches of optical navigation.
NASA will use data gathered from LuGRE to refine operational lunar GNSS systems for future missions.
NASA is developing capabilities that will allow missions at the Moon to leverage signals from GNSS constellations. These signals already used on many Earth-orbiting spacecraft will improve timing, enhance positioning accuracy, and assist autonomous navigation systems in cislunar and lunar space.
In 2023, the Lunar GNSS Receiver Experiment (LuGRE), developed in partnership with the Italian Space Agency, will demonstrate and refine this capability on the Moons Mare Crisium basin. LuGRE will fly on a Commercial Lunar Payload Services mission delivered by Firefly Aerospace of Cedar Park, Texas. NASA will use data gathered from LuGRE to refine operational lunar GNSS systems for future missions.
Illustration of Firefly Aerospaces Blue Ghost lander on the lunar surface. The lander will carry a suite of 10 science investigations and technology demonstrations to the Moon in 2023 as part of NASAs Commercial Lunar Payload Services (CLPS) initiative.
Autonomous navigation software leverages measurements like radiometrics, celestial navigation, altimetry, terrain-relative navigation, and GNSS to perform navigation onboard without contact with operators or assets on Earth, enabling spacecraft to maneuver independently of terrestrial mission controllers. This level of autonomy enables responsiveness to the dynamic space environment.
Autonomous navigation can be particularly useful for deep space exploration, where the communications delay can hamper in-situ navigation. For example, missions at Mars must wait eight to 48 minutes for round trip communications with Earth depending on orbital dynamics. During critical maneuvers, spacecraft need the immediate decision-making that autonomous software can provide.
LunaNet is a unique communications and navigation architecture developed by NASAs Space Communications and Navigation (SCaN) program. LunaNets common standards, protocols, and interface requirements will extend internetworking to the Moon, offering unprecedented flexibility and access to data.
For navigation, the LunaNet approach offers operational independence and increased precision by combining many of the methods above into a seamless architecture. LunaNet will provide missions with access to key measurements for precision navigation in lunar space.
Artists conceptualization of Artemis astronauts using LunaNet services on the Moon. a unique approach to lunar communications and navigation. The LunaNet communications and navigation architecture will enable the precision navigation required for crewed missions to the Moon and place our astronauts closer to scientifically significant lunar sites, enhancing the our missions scientific output.

4 Space SPACs With Exciting Futures and Big Risks – InvestorPlace
Posted: at 6:00 am
Its hard to believe that two years ago there was basically no way for an investor to gain exposure to interstellar exploration. Now, thanks to the explosion of space SPACs (special purpose acquisition companies), there is a wealth of options.
Virgin Galactic (NYSE:SPCE) began the trend. In 2019, it announced that it was merging with Social Capital Hedosophia. Back then, SPACs were a still-unpopular route to the public markets, and one with a checkered history. SPCE stock in fact dropped below $8 not long after the merger close.
But as demand for, and supply of, SPACs exploded after the novel coronavirus pandemic arrived last year, space exploration companies jumped on board. Investors can pick and choose across various slices of the exploration market.
The big risk is whether the boom in space SPACs necessarily is a good thing. Increasingly, the SPAC trend as a whole looks a bit bubbly, and many pre- and post-merger stocks have pulled back sharply in recent weeks.
Its worth remembering, too, that one of the few space SPACs done so far was the merger of Row 44 and Global Eagle Acquisition in 2013. Global Eagle went bankrupt last year, and shareholders were wiped out.
Given the risks involved in space exploration, theres little doubt that at least one of the current space SPACs eventually will meet the same fate. For those investors willing to take on the risks, however, here are four space SPACs to consider:
Source: Andrzej Puchta / Shutterstock.com
At the moment, GNPK stock manages to be both compelling and yet full of question marks.
The case for the stock seems almost airtight. Genesis Park is merging with Redwire, a self-described space infrastructure company. Redwire provides robotics, antennas, sensors, camera systems, and even full satellites to commercial and government customers.
Redwires history spans decades. Its been built of late by aerospace-focused private-equity fund AE Industrial Partners precisely to be a company that serves the entire space market. Redwire estimates that market at $420 billion already, with growth to more than $2 trillion by 2040. As the company put it in its merger presentation this month, when space wins, Redwire wins.
And unlike so many other space SPACs indeed many other SPACs across multiple sectors Redwire already has an established business. The company estimates 2020 revenue at $119 million, with adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) of $13 million.
Both figures should grow nicely. Redwire expects 2025 revenue of $1.4 billion, with adjusted EBITDA of $250 million. With GNPK stock barely above the $10 merger price, its trading at less than 3x that latter figure.
This looks like huge growth in a huge market at a bargain price.
Of course, that itself raises a number of questions. With this kind of potential, why exactly is P-E fund AE giving up 43% ownership at this valuation? Redwire itself says it doesnt need the SPACs cash to fund its growth.
Is five-year revenue growth of over 10x really worth just 3x 2025 EBITDA? Or is the multiple a sign that the growth targets are hugely optimistic? Going back further, why did the myriad businesses acquired by AE sell so cheap?
To some extent, GNPK stock almost seems too good to be true. Add to that the common concerns about SPAC projections, and some skepticism might be warranted. Of course, with GNPK below $11, a good deal of skepticism remains priced in.

The shorthand case for VACQ stock was laid out by Barrons in early March, after Vector Acquisition announced its merger with Rocket Lab. Rocket Lab Is a Mini-SpaceX That Investors Can Buy Today, the headline blared.
SpaceX, of course, was founded by Tesla (NASDAQ:TSLA) chief executive officer Elon Musk. And the two companies do look like direct competitors. Both are building out proprietary satellite fleets. Both offer launch services to third parties.
One notable difference is valuation. SpaceX reportedly raised capital in February at a $74 billion valuation. With VACQ stock below $12, Rocket Lab has a pro forma market capitalization of about $5.6 billion.
SpaceX is bigger, operates bigger vehicles, and likely benefits from the Musk halo. But given the massive discrepancy in valuations, VACQ stock looks like it might be worth a flyer itself.

Osprey Technology is merging with BlackSky, a provider of real-time geospatial intelligence. A fleet of satellites which should grow from a current nine to 30 monitors activity worldwide. BlackSky then layers on artificial intelligence and machine learning capabilities plus data analytics to provide customers with the highest-quality intelligence.
Its an intriguing story. SFTW stock certainly looks cheap enough, at about 8x projected 2025 free cash flow.
Of course, like so many space SPACs, its those projections that raise some eyebrows. BlackSky is projecting exponential growth similar to that of Redwire, with revenue growing from $22 million in 2020 to $546 million in 2025.
The argument against SFTW is that the multiple to estimated cash flow in 2025 is not a sign of a cheap stock, but rather evidence that the market doesnt trust that estimate. With competitor Spire raising its own capital via a SPAC merger with NavSight (NYSE:NSH), BlackSky wont have the market to itself.
Again, all of the space SPACs are high risk and high reward. SFTW stock doesnt look any different.

Holicity is merging with another rocket launch company, Astra. Astra was the third private company to reach space, following SpaceX and Rocket Lab. Its ambitions go much, much further.
By 2025, Astra aims to be launching rockets almost daily. Between a worldwide network of dedicated launchpads along with a portable launch system, the company can serve multiple customers in multiple markets.
Theres an obvious risk of failure. Astras niche alone has over 100 startups, according to industry estimates. Astra aims to get to near-daily launches by 2025, a timeline that leaves little or no room for error or delays.
But there are obviously huge rewards too, while a pro forma valuation under $2 billion suggests big upside if Astra hits its goals or comes close. Like so many space SPACs, HOL stock is a go big or go home play.
On the date of publication, Vince Martin did not have (either directly or indirectly) any positions in the securities mentioned in this article.

US, China consulted on safety as their crafts headed to Mars – The Republic
Posted: at 6:00 am
BEIJING As their respective spacecrafts headed to Mars, China and the U.S. held consultations earlier this year in a somewhat unusual series of exchanges between the rivals.
Chinas National Space Agency confirmed Wednesday that it had working-level meetings and communications with NASA from January to March to ensure the flight safety of their crafts.
U.S. law bans almost all contacts between NASA and China over concerns about technology theft and the secretive, military-backed nature of Chinas space program.
However, exceptions can be made when NASA can certify to Congress that it has protections in place to safeguard information, acting NASA Administrator Steve Jurczyk said during a video meeting last week.
Jurczyk said the most recent exchange was about China providing orbital and other data for its Mars mission so they could analyze the risk of collision. We do have targeted engagement with them, he said.
His remarks were first reported by the SpaceNews website.
Jurczyk added that it will be up to the Biden administration and Congress to determine if and how the U.S. engages with China on non-military space activities as part of the nations overall China strategy.
As the administration and Congress sets those policies, we look forward to how we can contribute in respect to civil space dialogue and collaboration with China, he said.
The area around Mars has become a bit more crowded this year with the arrival of spacecraft from the U.S., China and the U.A.E.
NASAs Perseverance rover landed on Mars in February and has begun exploration. Chinas Tianwen-1 is orbiting Mars in preparation for a landing in May or June. The U.A.E. craft is only orbiting and will not attempt to land.

Astronaut Mark Vande Hei Expects A ‘Surprisingly Calm’ Trip To International Space Station – Here And Now
Posted: at 5:57 am
NASA astronaut Mark Vande Hei is preparing for his second trip to the International Space Station.
He and two Russian cosmonauts are scheduled to launch from Kazakhstan on Friday, April 9. Vande Hei completed his first spaceflight in 2018 and spent 168 days at the space station. This time, he could be up there for twice as long.
Vande Hei says he expects a surprisingly calm trip on board Russias Soyuz spacecraft.
A lot of our training involves everything possible going wrong. We get trained on how to respond to all that, he says. But we very rarely get to experience what a space flight will really be like when a spacecraft, ideally, will work just fine.
It takes 8 minutes to get into orbit, he says, and the spacecraft should arrive at the station three hours after launch.
Vande Hei might need to give up his seat on a return flight to Earth in the fall because a Russian film crew will be at the space station making a movie, meaning he wouldnt come home until the spring of 2022. Astronauts understand that their assigned mission might change, he says.
If I do end up staying in space for a year, that's a great deal for me, he says. Again, I'm not certain that's going to happen, but if it ended up being the situation I'm in, I think it's a new opportunity a new life experience that I've never had before.
Vande Hei describes working at the International Space Station as a fantastic science lab in a basement with a beautiful view of the Alps behind the boiler. Theres plenty of space at the station, which is as big as a six-bedroom house, unlike the tiny but efficient spacecraft that will take him up there.
When you get a chance to look out the window, you cannot get a better view than that spot, he says. But it's not your normal work environment.
A few other Americans have made trips to space for more than 300 days. Vande Hei says hes most concerned about his bone density after losing 7% on his previous flight.
He regained all of his bone density but recovery took time. On his upcoming trip, he intends to persevere his bone density by carefully following his nutrition and exercise plan.
A much longer trip to a faraway planet like Mars poses major physical and psychological challenges for astronauts, Vande Hei says. On top of the length of the flight, he thinks humans will struggle to see their home planet in the way earthlings view Mars in the night sky.
Imagine what it would be like looking back: This place where all the people you love your entire life history before that time looking back and it just looks like a faint blue star out there in this vast field of other stars, he says. I think it's going to be hard for humans to be that far away from home.
But Vande Hei believes that humans will take the risk and make the long trip to Mars anyway.
Even crossing the Atlantic or Pacific to get to new places, that involved tremendous risks, he says. We've still done them and I'm sure we'll do them again.

SpaceX is outfitting its Dragon spacecraft with an observation dome for space tourists – TechCrunch
Posted: at 5:57 am
SpaceX is set to make a change to its Crew Dragon spacecraft for its forthcoming history-making all-civilian launch, currently set for September 15. That Dragon will replace its International Space Station docking mechanism with a transparent dome, through which passengers will be able to take in an awe-inspiring panorama of space and the Earth from an orbital perspective.
The glass dome will be at the nose of the Dragon capsule, or its topmost point when its loaded upright on top of a Falcon 9 rocket readying for launch. There should be space for one passenger to use it at a time, and itll be opened up once the spacecraft is safely out of Earths atmosphere, exposed by a protective cover that can be flipped back down to protect the observation deck when the spacecraft re-enters on its return trip.
SpaceX CEO Elon Musk called it the most in space you could possibly feel in a tweet sharing a concept render of the new modification in use. During a press briefing for the upcoming tourist flight, which is called Inspiration4 and led by billionaire Jared Isaacman, it was described as being similar to the exiting cupola on the International Space Station in terms of the views it affords.
The ISS cupola is an observatory module built by the European Space Agency (ESA) and installed in 2010. Based on these renders from SpaceX, the Dragon version will be a continuous unbroken transparent surface, whereas the ISS cupola is made up of segmented panes separated by support structure, so that could mean Dragon provides a better view.

This modification could pave the way for a more permanent alternate configuration of Dragon, one best-suited for SpaceXs planned commercial passenger missions, most of which will likely aim to do orbital tours without any actual docking at the ISS. Its possible the company will make further cabin modifications when the vehicle isnt configured for crew delivery to the orbital science station.
SpaceX also revealed new details about the Inspiration4 mission today, including its planned launch date of September 15, and a three-day mission flight duration. The remaining two passengers on board the four-person crew were also revealed this morning.

When to see the International Space Station in Lancashire skies this week – Lancs Live
Posted: at 5:57 am
Night owls across Lancashire will be able to see the International Space Station over the next few nights.
Tonight (March 30) the ISS will be visible to the naked eye at around 9.13pm for a period of around five minutes at a height of 33 degrees.
The ISS is visible when the sunlight reflects off of it and comes back down to Earth and this evening residents in parts of Lancashire should be able to spot its distinctive V shape.
Budding astronomer Linda Preston snapped an impressive photo above Darwen earlier this week.
The ISS always appears from the South West and travels in a straight line to the East.
The International Space Station is a large spacecraft that has been orbiting the earth since its launch on November 20, 1998, and travels at 17.500mph at an altitude of roughly 200 miles.
It has been permanently staffed by rotating crews of astronauts and cosmonauts since November 2000.
Research conducted aboard the ISS, which is the size of a football pitch, often requires one or more of the unusual conditions present in low Earth orbit, such as low-gravity or oxygen.
ISS studies have investigated human research, space medicine, life sciences, physical sciences, astronomy and meteorology.

20 Years Ago: Space Station Mir Reenters Earths Atmosphere and Disintegrates – SciTechDaily
Posted: at 5:57 am
In the Soviet mission control center, known by the Russian acronym TsUP, in Kaliningrad, now Korolev, outside of Moscow, controllers monitor the countdown for the launch of Mirs base block module on February 19, 1986.
On March 23, 2001, after 15 years in orbit, Russias space station Mir reentered over the Pacific Ocean following a controlled deorbit maneuver. Despite highly publicized incidents late in its orbital life, Mir secured its place in history as the first modular space station that enabled semi-permanent human habitation in low-Earth orbit.
The destination for a generation of Russian cosmonauts, Mir, provided opportunities for astronauts from other countries and space agencies to conduct research for their national programs on a commercial basis. The Shuttle-Mir Program saw nine space shuttle missions dock with Mir, and seven American astronauts join their Russian colleagues on long-duration expeditions as the two nations learned to work together in preparation for building and operating the International Space Station (ISS).
The launch of Mirs base block module at the Baikonur Cosmodrome in Soviet Kazakhstan.
The Mirs base block module as seen by the first expedition crew in March 1986.
The Soviet Union approved the Mir space station program in 1976, its modular elements based on hardware and technologies developed during the Salyut and Almaz space station programs of the 1970s. The most significant improvement involved adding a docking hub at the core modules forward end that could accommodate the addition of four large research modules.
On February 19, 1986, the Soviet Union launched Mirs first element, called the base block or core module, enabling crews to live aboard. Over the next several years, the Soviets added five research modules, including two partially outfitted with science equipment provided by the United States as part of the Shuttle-Mir Program, to expand its capabilities and habitable volume. The overall mass of the complex increased from 45,000 pounds to 285,900 pounds, and its habitable volume from 3,200 cubic feet to 12,400 cubic feet, at the time the largest spacecraft in orbit.
During its 13 years of human occupancy, Mir hosted 104 cosmonauts and astronauts from 13 countries and space agencies.
Space shuttle Atlantis docked with Mir in July 1995.
The first crew to occupy Mir, Leonid D. Kizim and Vladimir A. Solovev, launched on March 13, 1986. During their 125-day mission, they not only began commissioning the new station but also spent 50 days at the older Salyut-7 space station, conducting experiments and bringing 880 pounds of equipment, including a guitar, back to Mir.
By the time Sergei V. Zalyotin and Aleksandr Y. Kaleri, the 28th and final main expedition crew, departed the station on June 16, 2000, Mir accumulated an impressive series of accomplishments. Among these were the three longest space missions to date, extending the spaceflight record first to 326 days, then to 366 days, and finally to 438 days, a record that stands to this day.
Mir photographed by the STS-91 crew in June 1998.
Mir hosted nine international astronauts as part of long-duration missions, including seven Americans as part of the Shuttle-Mir program and numerous short-term visitors, including the crews of nine space shuttle missions. Of the Mir visitors, 42 went on to fly on the ISS, bringing their previous experience to bear on the assembly and operations of the new facility.
Mirs first resident crew, Leonid D. Kizim, left, and Vladimir A. Solovyov, prepare to board their spacecraft at the launch pad at the Baikonur Cosmodrome in Soviet Kazakhstan.
Mirs controlled deorbit and reentry followed a carefully planned stepwise approach. On October 19, 2000, Progress M43 arrived at Mir and used its engines to boost the station to a higher orbit, allowing for a controlled deorbit early the following year.
Mir expedition 18 Commander Vladimir N. Dezhurov, left, and STS-71 Commander Robert L. Hoot Gibson shake hands during the first Shuttle-Mir Program docking.
Progress M1-5 arrived on January 27, 2001, carrying 5,900 pounds of propellant for the deorbit burns. Through February, Mir lost orbital altitude at a somewhat unpredictable rate of 200 to 650 meters per day, the uncertainty caused by variability in solar heating of the Earths upper atmosphere. On February 19, the space station celebrated 15 years of in-orbit operations.
Mirs final resident crew, Sergei V. Zalyotin, left, and Aleksandr Y. Kaleri following their landing in Kazakhstan.
By March 1, its altitude had dropped to 164 miles, and the rate of descent increased to one mile per day. In the early morning hours, Moscow time, of March 23, Progress M1-5 fired its eight docking and attitude control thrusters, generating a total thrust of 220 pounds, for nearly 22 minutes. This changed Mirs orbital altitude to 136 by 117 miles. One orbit later, a second burn lasting 24 minutes dropped the low point of Mirs orbit to 98 miles. Mir then completed two more orbits around the Earth before the final burn using the Progress thrusters and its main rendezvous engine for a total of 660 pounds of thrust. Controllers allowed the engines to burn to fuel depletion as Mir passed out of radio contact with the ground.
Debris of Mir streaking through the sky as seen from Fiji as it reentered the Earths atmosphere.
Mir entered the Earths atmosphere at an altitude of about 62 miles and began to disintegrate at about 50 miles. Debris impacted the south Pacific east of New Zealand. Among those present to observe Mirs reentry from the island nation of Fiji were Mir designer Leonid A. Gorshkov and cosmonauts Sergei V. Avdeyev, Yelena Y. Kondakova, Musa K. Manarov, and Vladimir G. Titov, all of whom spent at least six months aboard Mir.
Also, monitoring and controlling Mirs deorbit and reentry were the operators in the Russian flight control center (TsUP is the Russian acronym) located in the Moscow suburb of Korolev. Their professionalism in carrying out the task must have been mixed with strong emotions as they watched the end of the space station on which many had devoted their entire careers, working in the TsUP for all of the base blocks 86,331 orbits around the Earth as it traveled 2.2 billion miles. The workers took solace that the ISS was in its earliest stages of assembly, and many of the lessons learned from Mir, including how to deorbit such a large spacecraft, would be passed on to the new program.

Space wine: Researchers analyse wine that spent year on ISS – Al Jazeera English

It tastes like rose petals. It smells like a campfire. It glistens with a burnt-orange hue. What is it? A 5,000-euro ($5,900) bottle of Petrus Pomerol wine that spent a year in space.
Researchers in Bordeaux are analysing a dozen bottles of the precious liquid along with 320 snippets of Merlot and Cabernet Sauvignon grapevines that returned to Earth in January after a sojourn aboard the International Space Station.
They announced their preliminary impressions on Wednesday mainly, that weightlessness didnt ruin the wine and it seemed to energise the vines.
Organisers say its part of a longer-term effort to make plants on Earth more resilient to climate change and disease by exposing them to new stresses, and to better understand the aging process, fermentation and bubbles in wine.
At a one-of-a-kind tasting this month, 12 connoisseurs sampled one of the space-travelled wines, blindly tasting it alongside a bottle from the same vintage that had stayed in a cellar.
A special pressurized device delicately uncorked the bottles at the Institute for Wine and Vine Research in Bordeaux. The tasters solemnly sniffed, stared and eventually, sipped.
I have tears in my eyes, Nicolas Gaume, CEO and co-founder of the company that arranged the experiment, Space Cargo Unlimited, told The Associated Press.
Alcohol and glass are normally prohibited on the International Space Station, so each bottle of wine was packed inside a special steel cylinder during the journey [File: NASA via AP]Alcohol and glass are normally prohibited on the International Space Station, so each bottle was packed inside a special steel cylinder during the journey.
At a news conference Wednesday, Gaume said the experiment focused on studying the lack of gravity which creates tremendous stress on any living species on the wine and vines.
We are only at the beginning, he said, calling the preliminary results encouraging.
Jane Anson, a wine expert and writer with Decanter, said the wine that remained on Earth tasted a little younger than the one that had been to space.
Chemical and biological analysis of the wines aging process could allow scientists to find a way to artificially age fine vintages, said Dr Michael Lebert, a biologist at Germanys Friedrich-Alexander-University who was consulted on the project.
The vine snippets known as canes in the grape-growing world not only survived the journey but also grew faster than vines on Earth, despite limited light and water.
Once the researchers determine why, Lebert said that could help scientists develop sturdier vines on Earth and pave the way for grape-growing and winemaking in space.
Christophe Chateau of the Bordeaux Wine-Makers Council welcomed the research as a good thing for the industry, but predicted it would take a decade or more to lead to practical applications. Chateau, who was not involved in the project, described ongoing efforts to adjust grape choices and techniques to adapt to ever-warmer temperatures.
The wine of Bordeaux is a wine that gets its singularity from its history but also from its innovations, he told The AP. And we should never stop innovating.
Private investors helped fund the project, which the researchers hope to continue on further space missions. The cost wasnt disclosed.
For the average earthling, the main question is: What does cosmic wine taste like?
For me, the difference between the space and Earth wine it wasnt easy to define, said Franck Dubourdieu, a Bordeaux-based agronomist and oenologist, an expert in the study of wine and winemaking.
Researchers said each of the 12 panelists had an individual reaction. Some observed burnt-orange reflections. Others evoked aromas of cured leather or a campfire.
The one that had remained on Earth, for me, was still a bit more closed, a bit more tannic, a bit younger. And the one that had been up into space, the tannins had softened, the side of more floral aromatics came out, Anson said.
But whether the vintage was space-flying or earthbound, she said, They were both beautiful.

Space News: Observing lightning from the International Space Station – Lake County News
Posted: at 5:57 am
If youre on the ground during a thunderstorm, you might witness a spectacular show of lightning.
But if youre observing that same thunderstorm from the vantage point of the International Space Station, you might see a bolt of energy shooting up from the clouds. And it might be red. Or blue. Or even green.
These particle outbursts are like nothing seen from the ground, and may prove useful to predict weather outcomes more precisely, better understand changes to our climate and increase the safety of planes and ships approaching dangerous storms.
They have names that sound like they were taken from a fantasy novel: Blue Jet. Gigantic Jet. Red Sprite. Halos and Elves. But all belong to a more scientific-sounding family, transient luminous events or TLEs; flashes and glows that appear above storms that are results of activity occurring in and below those storms.
Dr. Timothy Lang is a lead research aerospace technologist at NASAs Marshall Space Flight Center. He explainED how two key observational instruments aboard the orbiting laboratory are helping scientists better understand these colorful bursts of energy:
We use the Lightning Imaging Sensor, or LIS, to map lightning in two dimensions with global-scale coverage. It shows us where the thunderstorms are taking place, and how powerful each one is based on the size of its lightning flashes. So its akin to a macro camera. Another instrument, the Atmosphere-Space Interactions Monitor, or ASIM, is operated by the European Space Agency. ASIM gives us very fine detail of a TLEs flash. In essence, its akin to a micro camera, Lang said.
Torsten Neubert, ASIM Principal Investigator at Denmarks National Space Institute addED that ASIM and LIS make observations in different ranges of the color spectrum, allowing for different views of these particle events.
So, LIS is macro; ASIM is micro, and together they provide a powerful combination for exploring lightning and TLEs.
The space station offers an excellent vantage point to scientists studying TLEs. At about 250 miles up, it is much closer to these phenomena than a geosynchronous satellite. Further, the stations orbit allows for coverage of storms world-wide.
All this allows LIS and ASIM to produce a unique space-based dataset of thunderstorms and their effects, which in turn helps support other observational instruments. LIS for example, has been used to calibrate instruments and verify data for the Geostationary Lightning Mapper on NASA and NOAAs GOES satellites, and will also support the lightning imager on the European satellite, Meteosat Third Generation. This support helps make data produced by these sensors the highest quality for serving the public.
From the space station, LIS can provide lightning data in near-realtime for the benefit of those on Earth. It can report lightning nearing dry areas of forests prone to wildfires. Its integrated into the NOAA Aviation Weather Center's operations, which provides weather forecasts and warnings to the US and international aviation and maritime communities. And, over time, it can map data points to help scientists observe changes to our climate over broad tracts of land and sea.
In short, studying lightning and its effects both below and above the clouds can have a big impact on how we view our planet. Doing so from the International Space Station is improving that view in ways that couldnt be accomplished anywhere else.
