A spacesuit is not just a fashion statement. It's a personal mobility system to keep astronauts safe as they explore the lunar surface.

This week on NASA’s Curious Universe podcast, we hear about the development of the next generation of spacesuits.

Space Shuttle Challenger made its first flight 40 years ago today for STS-6. With a crew of 4 astronauts (dubbed "The Geritol Bunch" as it was the oldest crew flown up to that time), it deployed the first of the Tracking and Data Relay Satellites (TDRS). go.nasa.gov/3nJu5bM

Apollo 6, the second all-up uncrewed test of the Saturn V, launched #OTD in 1968, the same day Martin Luther King, Jr. was assassinated.

While there were problems, NASA managers thought they were surmountable and the next launch would carry a crew. go.nasa.gov/3GDPNoj

Nitrogen dioxide is largely produced from vehicle emissions.

The team estimated that 1.85 million new asthma cases worldwide in 2019 were attributable to NO2. Two-thirds of those were in urban areas. go.nasa.gov/3Kx5T5u

Air quality is an important contributor to disease. #NPHW

NASA-funded scientists linked health outcomes to satellite measurements of air pollutants like nitrogen dioxide and fine particulate matter (PM2.5). go.nasa.gov/3Kx5T5u
#NASAEarth



Small, inhalable particles called PM2.5 can contribute to diseases and premature death.

A @nasa-funded study found that 2.5 billion city dwellers worldwide live in areas where PM2.5 exceeds @WHO guidelines, leading to 1.8 million deaths in 2019. go.nasa.gov/3MeCSg6

It’s quite a view from out there.

Today, NASA announced the crew of #Artemis II. Astronauts Wiseman, Glover, Koch, and Hansen will fly around the Moon, taking in the spectacular sights of the craggy lunar surface and our home planet in the distance. go.nasa.gov/3K9LSAg

Wildfire smoke is one of the largest sources of unhealthy air quality.

To help extinguish its health effects, Jason Vargo of the @SFFED uses @nasa satellite data to better understand wildfire smoke impacts and build healthier communities.

@nasa data is key for scientists to understand public health risks like wildfire smoke, dust storms, night lights and more to keep communities healthy. #NPHW

Bright nighttime lights disrupt circadian rhythms and cause sleep deficiency.

Scientists compared @nasa nightlight and @cdc health data and found that poorer, non-white neighborhoods experience more artificial light at night. #NPHW go.nasa.gov/3nBnuQx

cool 😀 can't wait to watch mankind going back to the moon.


...and rounding out our #Artemis II Moon crew: mission commander @Astro_Reid!

Reid Wiseman lived & worked aboard the @Space_Station as a flight engineer in 2014. He also commanded the undersea research mission NEEMO21, and most recently served as Chief of the @NASA_Astronauts.

Representing the @csa_asc on #Artemis II to the Moon is @Astro_Jeremy, from London, Ontario.

Jeremy Hansen was a fighter pilot before joining CSA, and currently works with NASA on astronaut training and mission operations. This will be Hansen’s first mission in space.
#NASA



Our #Artemis II pilot is @AstroVicGlover!

Victor Glover is part of our 2013 class of @NASA_Astronauts and was the pilot for NASA’s @SpaceX Crew-1 mission. He’s logged 3,000 flight hours in more than 40 different aircraft, and will pilot @NASA_Orion around the Moon.

Meet the first member of our #Artemis II Moon crew: mission specialist @Astro_Christina!

Christina Koch visited the @Space_Station in 2019, where she took part in the first all-woman spacewalk. She began her career as an electrical engineer at @NASAGoddard.

@ISpace_Station seems to be available. Probably the better one to use.

#Landsat data gives eradication specialists a head start at knowing where farmers are growing cotton, which typically isn’t reported until later in the growing season.

In this image, light green fields are cotton, while darker fields are mostly sorghum or corn.

And the near complete destruction of natural habitats.


Farmers in the Rio Grande Valley are using @nasa satellite data to stop infestations of a cotton-loving beetle early in the growing season before they become severe and spread.
