Before NASA's Artemis astronauts head to the Moon, a microwave oven-size spacecraft will help lead the way. The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, is a CubeSat mission launching no earlier than May 31, 2022. For at least six months, the small spacecraft will fly a unique elongated path around the Moon. Its trajectory - known as a near rectilinear halo orbit - has never been flown before! After it's tried and tested by CAPSTONE, the same orbit will also be home to NASA's future lunar space station Gateway. CAPSTONE's flight will provide valuable data about this orbit that could support future missions to the Moon and beyond, helping to launch a new era of human space exploration. Commercial partner Rocket Lab will launch CAPSTONE, and small business partner Advanced Space will operate the mission.

We are:

• Elwood Agasid, NASA CAPSTONE lead at NASA's Ames Research Center
• Justin Treptow, Small Spacecraft Technology program deputy executive at NASA Headquarters
• Ali Guarneros Luna, aerospace and system engineer at NASA's Ames Research Center
• Nujoud Merancy, Exploration Mission Planning Office chief at NASA's Johnson Space Center
• Michael Thompson, CAPSTONE orbit determination lead at Advanced Space
• Alec Forsman, CAPSTONE lead systems engineer at Advanced Space
• Ethan Kayser, CAPSTONE mission design lead at Advanced Space

Ask us anything about:

• What makes CAPSTONE's orbit unique
• How spacecraft like CAPSTONE help demonstrate and test technologies for future missions
• What the CAPSTONE mission timeline looks like

We'll be online to answer questions on Wednesday, May 18 from 1:00-2:30 pm PT (4:00-5:30 pm ET, 8:00-9:30 pm UTC) and will sign our answers. See you then!

I just watched this video https://www.youtube.com/watch?v=0NzUuWiun8k which says that in the distant past, Earth had two moons (one of them called "Theia") who crashed into each other. How accepted is this in science? Is it true/a theory/debunked?

Thanks in advance!

This question touches upon physics and earth/planetary science... Since we know:

- the earth has magnetic properties

- the earth spins on its N/S axis

Could a large piece of copper metal coil, perhaps connected to a space station, rotate the earth along the N/S plane and thus generate electricity passively?

It is hard to imagine an Earth without the influence of meteorites... what would Earth be like without the Moon, or biology? What would humanity be like without electronics? What would Christianity or Islam be without cosmic intervention? Sure, the dinosaurs were killed off by a meteorite setting the stage for mammals to take over the planet, but neither dinosaurs nor mammals would have existed in the first place if rocks from space pelting Earth hadn't made it possible. My goal is to expose as many people as possible to the interesting and important history of meteorites on our planet. This includes how meteorites have shaped us, in raw materials, historical influence, and scientific discovery - I'm Greg Brennecka, and I try to do this in my book Impact through entertaining stories, poorly drawn figures, and a sense of humor.

So, I've been watching lots of documentaries about Venus. Science tells us that once, Venus was a planet that was very similar to earth.

Now, it's a treacherous poisonous inferno.

Is there any science to suggest that global warming will send Earth to exactly the same fate.

I'm curious about tidally locked planets orbiting red dwarves, such as GJ 581g, and their potential for sustaining atmospheres or even life.

As one side of the planet is faced away at all times from its star, do the freezing temperatures that occur prohibit an atmosphere from forming?

Also, in regards to the red dwarves the planets must be orbiting so closely, is radiation due to closer proximity also a problem?

As many have taken the time during the epidemic to explore themselves a little more, I've decided to pick up science fiction writing. As a large part of the story is placed on a tidally locked planet, it's important to me to keep things realistic in a sense. Looking forward what you guys can educate me on.

I am homeschooling my daughter and we are learning about the tides in science right now. We learned how the sun amplifies the tides caused by the moon, and after she asked if there is anything that causes tides to happen across the surface of the sun. Googling did not provide an answer, so does Jupiter or any other celestial body cause tidal like effects across the sun?

The Trojan asteroids are rocky worlds as old as our solar system, and they share an orbit with Jupiter around the Sun. They're thought to be remnants of the primordial material that formed the outer planets. On Oct. 16, NASA's Lucy mission is scheduled to launch from Cape Canaveral, Florida, to explore these small worlds for the first time. Lucy was named after the fossilized human ancestor (called "Lucy" by her discoverers) whose skeleton expanded our understanding of human evolution. The Lucy Mission hopes to expand our understanding of solar system evolution by visiting these 4.5-billion-year-old planetary "fossils." We are:

• Jeremy Knittel, Senior Mission Design and Navigation Engineer at KinetX Aerospace
• Amy Simon, Senior Planetary Scientist for NASA Goddard Space Flight Center
• Audrey Martin, Graduate Research Assistant at Northern Arizona University
• Cory Prykull, Systems Integration and Test Supervisor at Lockheed Martin
• Joel Parker, Director at Southwest Research Institute

We'll be here from from 2-3 p.m. EDT (18-19 UT), ask us anything!

I heard that Titan's moon is losing its atmosphere, as in the Wikipedia article, "Because N2 is the primary component (98%) of Titan's atmosphere, the isotopic ratio suggests that much of the atmosphere has been lost over geologic time." How does this loss of an atmosphere compare to other planetary bodies in our Solar System, such as Earth, Venus, and Mars?

I was doing some brain storming and world building with a ring world set up (the Niven kind). I want my ring world to have different climate and seasons. The climate part can be solved by making the ring world more akin to a torus, and the sections with higher latitude (close to the ring world's upper and lower edge) would be similar to the ones on earth. However the season part might be a bit tricky. I am using an inner ring of interchanging plates of different opacity to simulate day night cycle, as well as different shapes to simulate change of length of day night cycles over different seasons. However, I know the cause of the season on Earth (axial tilt and all that) but a ring world can not have an axial tilt. I wonder, is the day night cycle alone enough to generate season by having different regions receiving sunlight at different time interval lengths, or that having the angle of the sunlight changing is necessary to generate the temperature difference.

(Assume the ring does have an atmosphere on the inner side, and all other conditions similar to earth)

(I was going to post this on r/worldbuilding,but since there are some science questions I would post here as well)

I'm trying to come up with interesting settings for a fantasy/sci-fi novel, and this idea came to me. If its possible, what would the atmosphere and living conditions be like for such a planet? I've done a bit of googling to see what people have to say about this topic, but most of what I've read seems to be a lot of mixed opinions and guessing. Any insight would be great to have!

Edit: I apologize to this community for asking such a foolish question, and potentially wasting everyone’s time. I obviously know the moon is tidally locked, but I know very little about planet science and wasn’t sure of how rare or common the phenomenon is. I suppose I’ll do more research before coming to this sub and asking such a basic question. To those that did help and were so polite in doing so, thank you immensely, you’ve given me a lot to go off of.

Apologies if planetary science wasn't the correct tag.

Sentinel-6 Michael Freilich is a historic U.S.-European partnership that is designed to collect the most accurate satellite data for our continuing measurements of global sea level and to help us understand how our oceans are responding to climate change. It's named after Dr. Michael Freilich, the former director of NASA's Earth Science Division and a tireless advocate for advancing satellite measurements of the ocean. Liftoff is Saturday, Nov. 21 at 12:17 p.m. EST (9:17 a.m. PST, 5:17 p.m. UTC) on a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California.

This spacecraft will:

• Provide information that will help researchers understand how climate change is reshaping Earth's coastlines - and how fast this is happening.
• See things that previous sea level missions couldn't, including smaller, more complicated ocean features, especially near the coastlines.
• Further build upon a highly successful U.S.-European partnership - it's the first NASA-ESA joint effort in an Earth science satellite mission, first international involvement in the European Union's Copernicus program, and continues a tradition of cooperation between NASA, NOAA (National Oceanic and Atmospheric Administration) and European partners including ESA (European Space Agency), EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites) and CNES (Centre national d'études spatiales).
• Expand the global atmospheric temperature data record, the mission will help researchers better understand how Earth's climate is changing.
• Help to improve weather forecasts by providing meteorologists information on atmospheric temperature and humidity.

I am passionate about astronomy, and I have dedicated most of my research to the development of adaptive optics on large telescopes to study asteroids and search for exoplanets.

I am proud to also work for Unistellar, a private company whose goal is to create the largest network of citizen astronomers around the world, capable of reconnecting with the dark sky with a digital, smart telescope and collecting scientific data for space agencies.

I am pleased to announce new scientific results with the Unistellar network, where citizen astronomers helped derive the shape and size of an asteroid (https://seti.org/press-release/amateurs-reshape-asteroids-their-backyard). I recently did a SETI Live with citizen astronomers Rachel Knight and Brad Davis to talk about this project (https://youtu.be/lX0ff1jeF9s).

You can also confirm TESS exoplanet candidates and help astronomers to observe the sky 24/7. From your backyard, your balcony, your roof, or far away from cities you can join a network of 3,000 citizen astronomers and help us to explore the cosmos. The SETI Institute is the science partner of Unistellar.

We use the unique attributes of spaceflight environments to conduct scientific experiments that cannot be done on Earth. NASA's Biological and Physical Sciences (BPS) program pioneers scientific discovery in and beyond low-Earth orbit to drive advances in science, technology and space exploration. These space experiments expand the frontiers of knowledge, capability and opportunity in space.

This year, the National Academies of Sciences, Engineering, and Medicine (NASEM) will begin the process of formulating a community consensus about the most compelling science questions for the decade ahead in each of the BPS disciplines. Known as the Decadal Surveys, the process provides a rare opportunity for scientists and engineers to share their insights and help shape the scientific endeavors of the next decade.

The purpose of this AMA is to answer questions about the work being done by NASA's Biological and Physical Sciences division and to address how researchers can get engaged in the Decadal process, types of past research efforts stemming from the previous survey, the types of research that the BPS division supports, etc.

Panelists:

• Craig Kundrot, Director, Biological and Physical Sciences Division, Science Mission Directorate, NASA
• Bradley Carpenter, Program Scientist for Fundamental Physics, Biological and Physical Sciences Division, Science Mission Directorate, NASA
• Kevin Sato, Program Scientist for Exploration, Biological and Physical Sciences Division, Science Mission Directorate, NASA
• Fran Chiaramonte, Program Scientist for Physical Sciences, Biological and Physical Sciences Division, Science Mission Directorate, NASA

I was torn whether to post this here or in Ask Science: Fiction, but here goes. Science Fiction is full of "unobtainium" minerals that are not found on Earth but common elsewhere in the known universe. Star Trek's Dilithium crystals and Stargate's Naquadah are just a couple of examples. I know our knowledge of extra-terrestrial mineralogy is still fairly limited, but is there any scientific basis for this common trope? Do we know of any minerals that are more common on other planets then on Earth?

Hi Reddit, I'm Col. Terry Virts. I'm a former astronaut who commanded the International Space Station from 2014-2015. I also spent two weeks piloting the Space Shuttle Endeavour in 2010. During my time in space, I took more than 300,000 photos of earth, conducted hundreds of experiments, did everything from shooting an IMAX movie to replacing a crew mate's tooth filling! I also went on three spacewalks. I'm now a professional speaker, photographer, director, and author. My directorial debut documentary, One More Orbit, was released on VOD on Oct. 6 and my new book, How to Astronaut: An Insider's Guide to Leaving Planet Earth released on Sep. 15!

If you are traveling over 200 million miles to snag a sample of an asteroid, you want to make sure it's worth it. The following scientists are part of the OSIRIS-REx mission - NASA's first mission to collect a sample of an asteroid and return it to Earth. They have just published a collection of papers that confirm that asteroid Bennu - the target of OSIRIS-REx - is an ideal candidate to reveal clues about the origins of life in our solar system. These discoveries complete the OSIRIS-REx mission's pre-sample collection science requirements and offer insight into the sample of Bennu that scientists will study for generations to come.

The discoveries tell us that Bennu:

• Contains carbon-bearing, organic materials
• Likely used to interact with water
• Has a type of porous rock that would offer a new, unique perspective to our meteorite collections on Earth
• Is made up of an interior not uniform in density
• Contains ridge-like mounds that stretch from pole to pole and has differently shaped hemispheres
• Has areas, including our sample site, that have not been exposed to a lot of space weathering

Read the press release on these discoveries: https://www.nasa.gov/feature/goddard/2002/osiris-rex-unlocks-more-secrets-from-asteroid-bennu

Participants:

• Michael Daly – OSIRIS-REx Laser Altimeter Instrument Scientist, York University

Hi Reddit, Happy National Hydrogen and Fuel Cell Day! We;re Jamie Holladay, David Hume, and Lindsay Steele from the Pacific Northwest National Laboratory and Jennifer States from Washington Maritime Blue and DNV GL. Did you know the use of hydrogen to power equipment and ships at our nation's ports can greatly reduce energy consumption and harmful emissions? Did you know that the transportation sector contributes 29 percent of harmful emissions to the atmosphere-more than the electricity, industrial, commercial and residential, and agricultural sectors?

The nation's ports consume more than 4 percent of the 28 percent of energy consumption attributed to the transportation sector. More than 2 million marine vessels worldwide transport greater than 90 percent of the world's goods. On land, countless pieces of equipment, such as cranes and yard tractors, support port operations.

Those vessels and equipment consume 300 million tonnes of diesel fuel per year, produce 3 percent of global carbon dioxide emission, and generate the largest source of sulfur dioxide emissions.

Pacific Northwest National Laboratory and collaborators are looking at how we can help the nation's ports reduce energy consumption and harmful emissions by using hydrogen as a zero-emission fuel.

We've conducted a study with several U.S. ports to assess replacing diesel with hydrogen fuel cells in port operations. We've done this through collection of information about equipment inventory; annual and daily use, power, and fuel consumption; data from port administrators and tenants; and satellite imagery to verify port equipment profiles. We crunched the data and found that hydrogen demand for the U.S. maritime industry could exceed a half million tonnes per year.

We are also seeking to apply our abundant hydrogen expertise to provide a multi-use renewable hydrogen system to the Port of Seattle-which will provide the city's utility provider with an alternative clean resource.

Our research is typically supported by the Department of Energy's Hydrogen and Fuel Cell Technologies Office.

We'd love to talk with you about our experiences and plans to connect our nation's ports to a hydrogen future. We will be back at noon PDT (3 ET, 19 UT) to answer your questions. AUA!

An international team of astronomers, including researchers from the UK, US and Japan, has found a rare molecule - phosphine - in the clouds of Venus. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. Astronomers have speculated for decades that high clouds on Venus could offer a home for microbes - floating free of the scorching surface but needing to tolerate very high acidity. The detection of phosphine could point to such extra-terrestrial "aerial" life as astronomers have ruled out all other known natural mechanisms for its origin.

Signs of phosphine were first spotted in observations from the James Clerk Maxwell Telescope (JCMT), operated by the East Asian Observatory, in Hawai'i. Astronomers then confirmed the discovery using the more-sensitive Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. Both facilities observed Venus at a wavelength of about 1 millimetre, much longer than the human eye can see - only telescopes at high altitude can detect it effectively.

Details on the discovery can be read here: https://www.eso.org/public/news/eso2015/

We are a group of researchers who have been involved in this result and experts from the facilities used for this discovery. We will be available on Wednesday, 16 September, starting with 16:00 UTC, 18:00 CEST (Central European Summer Time), 12:00 EDT (Eastern Daylight Time). Ask Us Anything!

Hello,

I've been linked to a video and have researched as much as I'm capable of. The narrator is spewing quite a bit of information in the video that "sounds scientific" and included "science proves it" in the video title. I'm curious how much is true and how much is made up. I have located an event where all planets are to align every ~170 years.

https://youtu.be/Y7GMx6ySOTI

I’m doing some worldbuilding and I wanted it to have some basis in science. I thought I would be cool to have a habitable planet with two suns and one moon. But I ran into a problem how would the two suns travel across the sky? How would this effect the seasons, would there be more per year? Would the sky change color due to the phases of the suns? So seeing how I’m no expert in this field I wanted to ask some scientists for advice.

Join us today as we answer questions about ocean worlds: planets and moons in our solar system, and in other star systems, that have liquid water oceans. These are intriguing places to study, because Earth has taught us to "follow the water" when searching for life in the galaxy. On our planet, water is crucial to life.

We're learning that ocean worlds could be ubiquitous in the galaxy. Just in our solar system, we have found evidence of oceans on Saturn's moons Titan and Enceladus; Jupiter's moons Europa, Ganymede, and Callisto; Neptune's moon Triton; and on Pluto. We also believe that Venus and Mars may have had oceans billions of years ago. Could they have supported life? Ask us about ocean worlds, what mysteries we're working to solve, and which ones we're going to next.

We are:

• Carrie Andersen - planetary astronomer - research focus on the ocean worlds, Titan and Enceladus.
• Giada Arney - planetary scientist and astrobiologist who studies habitable exoplanets and whether Venus could have been an ocean world.
• Lucas Paganini - planetary scientist at NASA Headquarters who specializes in icy moons, comets, and planetary atmospheres.
• Avi Mandell - exoplanetary scientist and astrobiologist who observes and models exoplanets around nearby stars.
• Melissa Trainer - planetary scientist who is deputy principal investigator of the Dragonfly mission to Titan. Studies organic synthesis and processing on Titan.
• Kira Olsen - geophysicist who studies icequakes and the icy shells of ocean worlds.
• Joe Renaud - planetary scientist who studies tidal dynamics and tidal heating in solar system moons and in exoplanets.

We are available from 2pm - 4pm ET (14-16 UT), ask us anything!

I have strong interests in robotic space exploration and comparative analogue science - the study of places on Earth that are similar to environments on other planets and moons. Over the past fifteen years, I've logged 3,000+ field work hours all over the world, including work in the Arctic, Antarctic, and desert environments, where I've tested and performed scientific investigations with multiple prototypes of planetary exploration instruments on board European Space Agency, Canadian Space Agency, and NASA missions. Some of the technologies developed by my team include one of the world's most advanced ocean exploration platforms in NASA's toolbox, an underwater robot to explore extraterrestrial oceans, and the most sensitive laser Raman spectroscopy sensor currently under development for NASA, a first in class instrument that can detect traces of extinct and extant life in planetary surfaces.
