Crazyspacesuit: Were You Aware Of The Overview Effect Before Experiencing It?

Whats the coolest thing u have seen or discovered???!!!! Like i mean cool as in something that made u nerd out! I used to want to work for nasa but found a love for teaching art instead so i find myself nersing out over the cool research yall put out! Much love from wise county texas!

Do you have any protections against asteroids?

It's a long ways down. This is a view from the vantage point of astronaut Shane Kimbrough during his spacewalk last Friday outside the International Space Station. Shane posted this photo and wrote, " View of our spectacular planet (and my boots) during the #spacewalk yesterday with @Thom_astro." During the spacewalk with Kimbrough and Thomas Pesquet of ESA, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections to prepare for its robotic move Sunday, March 26.

Two astronauts will venture outside the space station again this Thursday, March 30 for the second of three spacewalks. Kimbrough and Flight Engineer Peggy Whitson will begin spacewalk preparation live on NASA Television starting at 6:30 a.m. EST, with activities beginning around 8 a.m. Watch live online here.

How is it like to be a NASA Earth Scientist? What Subjects are you required to excel at to become one? Were you really good in your studies, when you were a young teenager?

What’s aboard SpaceX’s Dragon?

On Dec 5. 2019, a SpaceX Falcon 9 rocket blasted off from Cape Canaveral Air Force Station in Florida carrying a Dragon cargo capsule filled with dozens of scientific experiments. Those experiments look at everything from malting barley in microgravity to the spread of fire.

Not only are the experiments helping us better understand life in space, they also are giving us a better picture of our planet and benefiting humanity back on Earth. 

📸 A Better Picture of Earth 🌏

Every material on the Earth’s surface – soil, rocks, vegetation, snow, ice and human-made objects – reflects a unique spectrum of light. The Hyperspectral Imager Suite (HISUI) takes advantage of this to identify specific materials in an image. It could be useful for tasks such as resource exploration and applications in agriculture, forestry and other environmental areas.

🌱 Malting Barley in Microgravity 🌱

Many studies of plants in space focus on how they grow in microgravity. The Malting ABI Voyager Barley Seeds in Microgravity experiment is looking at a different aspect of plants in space: the malting process. Malting converts starches from grain into various sugars that can be used for brewing, distilling and food production. The study compares malt produced in space and on the ground for genetic and structural changes, and aims to identify ways to adapt it for nutritional use on spaceflights.

🛰️ A First for Mexico 🛰️

AztechSat-1, the first satellite built by students in Mexico for launch from the space station, is smaller than a shoebox but represents a big step for its builders. Students from a multidisciplinary team at Universidad Popular Autónoma del Estado de Puebla in Puebla, Mexico, built the CubeSat. This investigation demonstrates communication within a satellite network in low-Earth orbit. Such communication could reduce the need for ground stations, lowering the cost and increasing the number of data downloads possible for satellite applications.

🚀 Checking for Leaks 🚀

Nobody wants a spacecraft to spring a leak – but if it happens, the best thing you can do is locate and fix it, fast. That’s why we launched the first Robotic External Leak Locator (RELL) in 2015. Operators can use RELL to quickly detect leaks outside of station and help engineers formulate a plan to resolve an issue. On this latest commercial resupply mission, we launched the Robotic Tool Stowage (RiTS), a docking station that allows the RELL units to be stored on the outside of space station, making it quicker and simpler to deploy the instruments.

🔥 The Spread of Fire 🔥

Understanding how fire spreads in space is crucial for the safety of future astronauts and for controlling fire here on Earth. The Confined Combustion investigation examines the behavior of flame as it spreads in differently-shaped spaces in microgravity. Studying flames in microgravity gives researchers a chance to look at the underlying physics and basic principles of combustion by removing gravity from the equation.

💪 Staying Strong 💪

Here on Earth you might be told to drink milk to grow up with strong bones, but in space, you need a bit more than that. Astronauts in space have to exercise for hours a day to prevent substantial bone and muscle loss. A new experiment, Rodent Research-19, is seeing if there is another way to prevent the loss by targeting signaling pathways in your body at the molecular level. The results could also support treatments for a wide range of conditions that cause muscle and bone loss back here on Earth.

How Well Do You Know Venus?

Similar in structure and size to Earth, Venus’ thick, toxic atmosphere traps heat in a runaway greenhouse effect. A permanent layer of clouds traps heat, creating surface temperatures hot enough to melt lead.

How did Venus get its name? It is named for the ancient Roman goddess of love and beauty. It is believed that Venus was named for the most beautiful of the ancient gods because it shone the brightest of the five planets known to ancient astronomers.

Here are a few fun facts that you might not know:

One day on Venus lasts as long as 243 Earth days (aka the time it takes for Venus to rotate or spin once)

Venus is a rocky planet, also known as a terrestrial planet

Venus’ thick and toxic atmosphere is made up mostly of carbon dioxide and nitrogen, with clouds of sulfuric acid droplets

Venus has no moons or rings

More than 40 spacecraft have explored the planet

No evidence of life has been found on Venus. The planet’s extreme high temperatures of almost 480 degrees Celsius (900 degrees Fahrenheit) makes it seem an unlikely place for life as we know it

Venus spins backwards when compared to the other planets. This means that the sun rises in the west and sets in the east

Night Light

Did you know that Venus is the brightest planet in Earth’s dark skies? Only the moon — which is not a planet — is brighter. Venus outshines the other planets because it is closer and its thick cloud cover is excellent at reflecting sunlight.

What Happened to Mars?

Billions of years ago, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. A thick atmosphere blanketed the planet and kept it warm.

Today, Mars is bitter cold. The Red Planet’s thin and wispy atmosphere provides scant cover for the surface below.

Our MAVEN Mission

The Mars Atmosphere and Volatile EvolutioN (MAVEN) mission is part of our Mars Scout program. This spacecraft launched in November 2013, and is exploring the Red Planet’s upper atmosphere, ionosphere and interactions with the sun and solar wind.

The purpose of the MAVEN mission is to determine the state of the upper atmosphere of Mars, the processes that control it and the overall atmospheric loss that is currently occurring. Specifically, MAVEN is exploring the processes through which the top of the Martian atmosphere can be lost to space. Scientists think that this loss could be important in explaining the changes in the climate of Mars that have occurred over the last four billion years.

New Findings

Today, Nov. 5, we will share new details of key science findings from our ongoing exploration of Mars during a news briefing at 2 p.m. EDT. This event will be broadcast live on NASA Television. Have questions? Use #askNASA during the briefing.

5 Ways Studying Water Will Help Us Better Understand Earth

Studying our home planet is just as powerful as exploring what’s beyond it.

Surface Water and Ocean Topography (SWOT) is a joint mission developed by NASA and the French space agency Centre National d’Études Spatiales (CNES), with contributions from the Canadian Space Agency and the UK Space Agency. It will track water on more than 90% of Earth’s surface and help communities, scientists, and researchers better understand this finite and vital resource. And it’s launching this month!

So how will SWOT help us better understand Earth? Here are 5 ways.

SWOT will address some of the most pressing climate change questions of our time.

An important part of predicting our future climate is determining at what point Earth’s ocean water slows down its absorption of the excess heat in the atmosphere and starts releasing that heat back into the air, where it could accelerate global warming. SWOT will provide crucial information about this global heat exchange between the ocean and the atmosphere, enabling researchers to test and improve future climate forecasts.

The satellite will also offer insights to improve computer models for sea level rise projections and coastal flood forecasting.

Data from SWOT will additionally help scientists, engineers, water managers, and others better monitor drought conditions in lakes and reservoirs and improve flood forecasts for rivers.

SWOT is the first satellite mission that will observe nearly all water on the planet’s surface.

SWOT will measure the height of water in Earth’s lakes, rivers, reservoirs, and the ocean, giving scientists the ability to track the movement of water around the world.

SWOT’s eye in the sky will provide a truly global view of the water on more than 90% of Earth’s surface, enriching humankind’s understanding of how the ocean reacts to and influences climate change along with what potential hazards – including floods – lie ahead in different regions of the world.

SWOT will see Earth’s water in higher definition than ever before.

Because everything is better in HD 😉, SWOT will view Earth’s ocean and freshwater bodies with unprecedented clarity compared to other satellites, much like a high-definition television delivers a picture far more detailed than older models. This means that SWOT will be able to “see” ocean features – like fronts and eddies – that are too small for current space-based instruments to detect. Those measurements will help improve researchers’ understanding of the ocean’s role in climate change.

Not only will the satellite show where – and how fast – sea level is rising, it will also reveal how coastlines around the world are changing. It will provide similar high-definition clarity for Earth’s lakes, rivers, and reservoirs, many of which remain a mystery to researchers, who aren’t able to outfit every water body with monitoring instruments.

SWOT data will be used to help make decisions about our daily lives and livelihoods.

As climate change accelerates the water cycle, more communities around the world will be inundated with water while others won’t have enough. SWOT data will be used to monitor drought conditions and improve flood forecasts, providing essential information to water management agencies, disaster preparedness agencies, universities, civil engineers, and others who need to track water in their local areas. SWOT data also will help industries, like shipping, by providing measurements of water levels along rivers, as well as ocean conditions, including tides, currents, and storm surges.

Finally … SWOT will pave the way for future Earth missions.

With its innovative technology and commitment to engaging a diverse community of people who plan to use data from the mission, SWOT is blazing a trail for future Earth-observing missions. SWOT’s data and the tools to support researchers in analyzing the information will be free and accessible. This will help to foster research and applications activities by a wide range of users, including scientists, resource managers, and others who in the past may not have had the opportunity to access this kind of information. Lessons learned from SWOT will lead to new questions and improvements for future missions, including our upcoming Earth System Observatory, a constellation of missions focused on studying key aspects of our home planet.

NASA’s View of COVID-19

#COVID19 led to changes in human activities around the globe. We can see some of these changes from space. Some bodies of water have run clearer, emissions of pollutants have temporarily declined, and transportation and shipment of goods have decreased.

Along with our partner agencies – ESA and JAXA – we’re making satellite data available on the COVID-19 Earth Observation Dashboard, where you can explore some of the changes we can see from space.

But it’s not just what we can see. When the pandemic began, NASA engineers sprang into action to build ventilators, oxygen hoods and more to help save lives.
