On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance.
New findings by NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission indicate that solar wind is currently stripping away the equivalent of about 1/4 pound of gas every second from the Martian atmosphere. MAVEN tracked a series of dramatic solar storms passing through the Martian atmosphere in March and found the loss was accelerated.
This image shows the galaxy Messier 94, which lies in the small northern constellation of the Hunting Dogs, about 16 million light-years away. Within the bright ring or starburst ring around Messier 94, new stars are forming at a high rate and many young, bright stars are present within it.
The Hubble space telescope has captured a stunning image of a faraway galaxy known as a barred spiral. Galaxy NGC 4639 is located over 70 million light-years away from Earth in the constellation of Virgo. NGC 4639 is one of about 1500 galaxies that make up the Virgo Cluster, according to the European Space Agency (ESA), one of NASA’s Hubble partners.
NASA aims to extend human presence deeper into the solar system and to the surface of Mars. In doing so, our human and robotic explorers will expand knowledge and discover the potential for life beyond Earth. Our goal is not bound by a single destination. We seek the capacity for people to work, learn, operate, and sustainably live safely beyond Earth for extended periods of time. We will achieve this goal with a growing number of international and commercial partners, realizing economic benefits and strengthening America’s leadership on Earth and in space.
NASA has selected 27 organizations from across the United States to begin negotiations for cooperative agreement awards totaling $42 million to implement a new strategic approach to more effectively engage learners of all ages on NASA science education programs and activities.
NASA’s New Horizons spacecraft has returned the best color and the highest resolution images yet of Pluto’s largest moon, Charon – and these pictures show a surprisingly complex and violent history. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula.
A news conference was held on Sept. 24 at NASA’s Johnson Space Center with the next crew launching to the International Space Station, including NASA astronaut Tim Kopra. ESA astronaut Timothy Peake, cosmonaut Yuri Malenchenko of the Russian Federal Space Agency and Kopra will launch to the station aboard a Soyuz spacecraft on Dec. 15 from the Baikonur Cosmodrome in Kazakhstan. They’re currently scheduled to return to Earth in May 2016.
Actress Nichelle Nichols recently flew on board NASA's Stratospheric Observatory for Infrared Astronomy, SOFIA, the world's largest airborne observatory. Ms. Nichols has been collaborating with NASA for years, actively recruiting into the astronaut corps and into STEM careers. During her flight, Ms. Nichols recorded this short message highlighting the important research NASA is doing to further humankind's exploration of the solar system and beyond.
In this video, Karl Battams of the Naval Research Lab talks us through a visualization of the comets that SOHO has witnessed. Since its launch nearly 20 years ago, NASA and the European Space Agency's Solar and Heliospheric Observatory has spotted 3000 comets.
