NASA finds evidence of life on Mars


Today’s Video of the Day from NASA reveals the discovery of organic molecules that have been preserved in surface rocks on Mars for billions of years. While it is not yet clear if the carbon-containing material was produced from living or non-living sources, the existence of organic molecules on the planet provides scientists with evidence that the conditions of Mars may have once been habitable.

The rocks were detected by NASA’s Curiosity rover, which heated the stones by 500 degrees Celsius to release the hydrocarbons. In collaboration with the European Space Agency, NASA will send a new generation of rovers to Mars in 2020 to search for further signs of microbial life.

Preparing the Earth and space for 5G


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at their Satellite for 5G (S45G) program which aims to prepare satellite and terrestrial services for the next generation of communication.

5G will change the way we communicate and work by providing extra-fast internet connection speeds and shorten delays. You’ll be able to be connected to everything everywhere and download a movie in just seconds.

Satellites will play an important role in allowing enhanced reliability and security to the new 5G revolution that terrestrial networks alone cannot provide.

The Space Storm Hunter’s journey to space


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at their Space Storm Hunter, also known as the Atmosphere-Space Interactions Mission, and its journey to space.

The instrument was launched on April 2nd, 2018 from the Kennedy Space Center in Florida and then was installed on the International Space Station.

According to ESA, this marks “the first time that such a set of sensitive cameras, light sensors and X- and gamma-ray detectors will study the anatomy of luminous phenomena in Earth’s upper atmosphere and bursts of high-energy radiation.”

NASA scientists uncover new magnetic process in space


Today’s Video of the Day comes from NASA’s Goddard Space Flight Center and features a look at how a team of scientists discovered a new type of magnetic process occurring near Earth.

The findings, which were reported in the journal Nature, detail how scientists working on NASA’s Magnetospheric Multiscale spacecraft (MMS) used an innovative technique to uncover this new type of magnetic reconnection.

What to look for in the sky during May 2018


Today’s Video of the Day comes from the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California and features a cheat sheet in what to look for in the sky during May 2018.

This month, NASA will launch its Mars InSight lander, which will be visible to many viewers on the West Coast, particularly in southern California.

May is also the best time of the year to see Jupiter in the night sky, particularly during mid-evening.

ESA’s new Horizons mission to launch June 6, 2018


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at astronaut Alexander Gerst as he prepares to command ESA’s upcoming Horizons mission.

The Horizons mission will launch on June 6, 2018 and will be Gerst’s second mission to the International Space Station. He will be joined by US astronaut Serena Auñón-Chancellor and Russian cosmonaut Sergei Prokopyev from the Baikonur cosmodrome.

According to ESA, “The mission name evokes exploring our Universe, looking far beyond our planet and broadening our knowledge. Alexander would also like to make people realise that there is always a chance to go beyond their personal horizons.”

New GEDI mission will monitor Earth’s forests in high resolution


Today’s Video of the Day comes from NASA’s Goddard Space Flight Center and features a look at a new mission aimed at monitoring Earth’s forests in high resolution and 3D.

The new GEDI instrument, which of course rhymes with Jedi, is a spaceborne laser that will sit perched on the exterior of the International Space Station. It will monitor Earth’s tropical and temperate forests and is expected to launch later this year.

“Scientists have been planning for decades to get comprehensive information about the structure of forests from space to deepen our understanding of how this structure impacts carbon resources and biodiversity across large regions and even globally, as well as a host of other science issues,” said Ralph Dubayah, GEDI principal investigator and a professor at the University of Maryland. “This is why seeing the instrument built and racing toward launch is so exciting.”

A musical tour of Italy from space


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at a tour of Italy shot from space and set to music.

The clip was filmed by ESA astronaut Paolo Nespoli on board the International Space Station using a RED Dragon camera and shows all the overhead beauty of the Italian peninsula.

The song featured in the video is “Daylight” by Roob Sebastian.

Europe on a perfectly clear day


Today’s Video of the Day comes from the European Space Agency’s Earth from Space series and features a look at what Europe would look like with zero cloud cover on a perfectly clear day.

Because it would be nearly impossible to catch a day without a single cloud over the continent, this mosaic composite image was created using several different cloud-free images taken by the Copernicus Sentinel-3A satellite.

Sentinel-3B lifts off into space


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at the second Copernicus Sentinel-3 satellite, Sentinel-3B, lifting off into space on April 25, 2018.

Sentinel-3B will join its twin, Sentinel-3A, in orbit to measure and collect data on oceans, ice, land, and the atmosphere. More specifically, the Sentinel-3 mission is geared towards oceanography, including the measuring of aquatic biological productivity, marine pollution, and changes in sea-level.

Training to walk on the moon


Today’s Video of the Day comes from the European Space Agency (ESA) and features a look at how astronauts are training to learn how to walk on the moon.

Since lunar gravity is only one sixth that of Earth, astronauts use specially weighted spacesuits in one of the deepest “swimming pools” in Europe.

This “moondive” study took place over the course of three years at ESA’s 10 meter deep Neutral Buoyancy Facility at the European Astronaut Centre near Cologne in Germany.
