Hi all,
Good morning from Florida…I hope everyone is doing well…another new month, time is going so fast, I know I say this often but, for me, it is almost beyond comprehension…last year at this time, we were beginning to hear allot about the virus…I was on my way to Brazil for a 6 week adventure…I had never been gone more than 3 weeks so it was going to be a huge challenge…I left with the idea of one day at a time and to only focus on each day as I pass through it…little did I realize two weeks later I would be trying to get back to the USA as the pandemic was affecting the world in the most negative way. I am sure we can all think back to when we realized that this is serious as many people were dying throughout the world…looking back at what has evolved for us in the USA and internationally there seems to be some hope as vaccines are becoming more available and we gain more knowledge. Some States in the USA are removing all restrictions so we will have to see where this takes us….I am hoping, towards the end of this year, I can get back to visiting schools but that will depend on individual countries’ and school permitting visitors…
We have to stay positive and always be thankful… remembering to do our best, enjoy everything we do, believe in ourselves, and let those we care about most know (I always say this, we all need to take it to heart) …hugs & smiles... :-) :-) STAY SAFE, TAKE CARE, Love ya, Gabe
I hope you have been following along with the progress of Perseverance on Mars…I think the clarity and detail of the pictures and videos have been amazing…when we look ahead as it explores, performing so many functions will be even more amazing….then with the launch of the helicopter, Ingenuity, it will be even more spectacular…check out the info on the links below….
look at the stars in this video…this is what we would see in the night sky if it were completely black on earth….

Celebrating Women’s History Month: Most Recent Female Astronauts
For Women’s History Month, NASA and the International Space Station <https://www.nasa.gov/mission_pages/station/main/index.html> celebrate the women who conduct science aboard the orbiting lab.
As of March 2021, 65 women have flown in space, including cosmonauts, astronauts, payload specialists, and space station participants. The first woman in space was Russian cosmonaut Valentina Tereshkova <http://www.gctc.ru/main.php?id=1097>, who flew on Vostok 6 on June 16, 1963. The first American woman in space, Sally Ride <https://www.nasa.gov/sites/default/files/atoms/files/ride_sally.pdf>, flew aboard the Space Shuttle STS-7 in June of 1983.
Other notable firsts:
Roscosmos <http://en.roscosmos.ru/> cosmonaut Svetlana Savitskaya <http://www.gctc.ru/main.php?id=1187> was the first woman to participate in a spacewalk on July 25, 1984.
NASA astronaut Mae Jemison <https://www.nasa.gov/sites/default/files/atoms/files/jemison_mae.pdf> flew on the Space Shuttle Endeavour's STS-47 mission in 1992, becoming the first black woman in space.
NASA astronaut Susan Helms <https://www.nasa.gov/sites/default/files/atoms/files/helms_susan.pdf> was the first female crew member aboard the space station, a member of Expedition 2 from March to August 2001.
NASA astronaut Peggy Whitson <https://www.nasa.gov/astronauts/biographies/peggy-a-whitson/> was the first female ISS Commander, starting April 2008, during a six-month tour of duty on Expedition 16.
The most women in space at one time <https://www.nasa.gov/image-feature/four-women-astronauts-pose-for-photo-aboard-the-space-station> (four) happened in 2010, when space shuttle Discovery visited the space station for the STS-131 mission. Discovery’s crew of seven included NASA astronauts Dorothy Metcalf-Lindenburger <https://www.nasa.gov/sites/default/files/atoms/files/metcalf-lindenburger_dorothy.pdf> and Stephanie Wilson <https://www.nasa.gov/astronauts/biographies/stephanie-d-wilson> and Japan Aerospace Exploration Agency (JAXA <http://global.jaxa.jp/>) astronaut Naoko Yamazaki <http://iss.jaxa.jp/en/astro/biographies/yamazaki/index.html>. The space station crew of six included NASA astronaut Tracy Caldwell Dyson <https://www.nasa.gov/astronauts/biographies/tracy-caldwell-dyson>.
Susan Helms shares the record for longest single spacewalk, totaling 8 hours 56 minutes, with fellow NASA astronaut Jim Voss.
Expedition 24 <https://www.nasa.gov/mission_pages/station/expeditions/expedition24/index.html> marked a first with two women, NASA astronauts Shannon Walker <https://www.nasa.gov/astronauts/biographies/walker-shannon> and Tracy Caldwell Dyson, assigned to a space station mission from April to September 2010.
The 2013 astronaut class <https://www.nasa.gov/astronauts/2013astroclass.html> was the first with equal numbers of women and men.
NASA astronaut Anne McClain <https://www.nasa.gov/astronauts/biographies/anne-c-mcclain> became the first woman to live aboard the space station as part of two different crews with other women: Serena Auñón-Chancellor <https://www.nasa.gov/astronauts/biographies/serena-m-aunon-chancellor/biography> in 2018 and Christina Koch <https://www.nasa.gov/astronauts/biographies/christina-h-koch> in 2019.
NASA astronauts Jessica Meir <https://www.nasa.gov/astronauts/biographies/meir-u-jessica> and Christina Koch <https://www.nasa.gov/astronauts/biographies/christina-h-koch> completed the first all-female spacewalk <https://www.youtube.com/watch?v=cNnvYACgwrE> in October 2019. They conducted two more spacewalks together in 2020.
Women have participated in scientific research on the space station since 2001 and have become an integral part of advances in the program. The second crew launch under the Commercial Crew Program <https://www.nasa.gov/exploration/commercial/crew/index.html>, currently scheduled for no earlier than Tuesday, April 20, 2021, includes NASA astronaut Megan McArthur <https://www.nasa.gov/astronauts/biographies/k-megan-mcarthur/>, shown here in Johnson Space Center’s Bldg. 5 Motion Based Simulator.

Rare red sprite and blue jet create otherworldly light show above Hawaii
Sprites and jets are fleeting atmospheric phenomena, hard enough to witness, let alone photograph.
But a new image from an observatory in Hawaii captures both a red sprite and a blue jet in the same shot. The photo, released on Feb. 24 <https://noirlab.edu/public/images/iotw2108a/>, comes courtesy a "cloud cam" at the Gemini North telescope, part of the International Gemini Observatory located on Maunakea.
Sprites and jets are upper-atmospheric phenomena caused by electrical discharges. Sprites, which are typically reddish-orange and sometimes blue-green, occur in the mesosphere, between 30 and 50 miles (50 and 80 kilometers) in altitude. They're often triggered by regular, lower-altitude lightning, but are much cooler in temperature. They're also sometimes shaped like jellyfish. Blue jets also occur at high altitude, triggered by a discharge of electricity from the positively-charged upper portion of a storm cloud to the negatively-charged cloud top, according to a paper published Jan. 20 in the journal Nature <https://go.redirectingat.com/?id=92X1590019&xcust=livescience_us_6823502523848045000&xs=1&url=https%3A%2F%2Fwww.nature.com%2Farticles%2Fs41586-020-03122-6&sref=https%3A%2F%2Fwww.livescience.com%2Fred-sprite-blue-jet-lightning-image-hawaii.html%3Futm_source%3DSelligent%26utm_medium%3Demail%26utm_campaign%3DLST_Newsletter%26utm_content%3DLST_Newsletter%2B%26utm_term%3D2868862>.

Cosmologists are pressing rewind on the first instant after the Big Bang by simulating 4,000 versions of the universe on a massive supercomputer.
The goal is to paint a picture of the immediate aftermath of the Big Bang, when the observable universe suddenly expanded 1 trillion trillion times in size in the tiniest sliver of a microsecond. By applying the method used for the simulations to real observations of today's universe, researchers hope to arrive at an accurate understanding of what this inflationary period looked like.
"We are trying to do something like guessing a baby photo of our universe from the latest picture," study leader Masato Shirasaki, a cosmologist at the National Astronomical Observatory of Japan (NAOJ), wrote in an email to Live Science.
Patchy universe
Today's universe shows variations in density, with some patches rich in galaxies and others relatively barren. One promising hypothesis for this uneven distribution of visible matter is that, at the time of the Big Bang, there were already quantum fluctuations, or random, temporary changes in energy, in the tiny, primordial universe, Shirasaki said.
When the universe expanded, these fluctuations would have expanded, too, with denser points stretching into regions of greater density than their surroundings. Gravitational forces would have interacted with these stretched-out filaments, causing galaxies to clump along them.
But gravitational interactions are complex, so trying to rewind this inflationary period to understand how the universe would have looked before it is very challenging. Cosmologists essentially need to remove the gravitational fluctuations from the equation.
A clean start
The researchers developed a reconstruction method to do just that. To find out if the reconstruction was accurate, though, they needed some way to test it. So they used NAOJ's ATERUI II supercomputer to create 4,000 versions of the universe, all with slightly different initial density fluctuations. The researchers allowed these virtual universes to undergo their own virtual inflations and then applied the reconstruction method to them, to see if it could get them back to their original starting points.
