US spacecraft enters Mars orbit, India probe next (Update)
NASA's Maven spacecraft entered orbit around Mars for an unprecedented study of the red planet's atmosphere following a 442 million-mile (710 million-kilometer) journey that began nearly a year ago.
MAVEN Mars spacecraft to begin orbit of Red Planet
A NASA spacecraft that aims to study the upper atmosphere of Mars and reveal how its climate changed over time is poised to begin orbiting the Red Planet on Sunday.
NASA's Maven spacecraft reaches Mars this weekend
Mars, get ready for another visitor or two. This weekend, NASA's Maven spacecraft will reach the red planet following a 10-month journey spanning 442 million miles (711 million kilometers).
Image: Rainbow aurora captured from space station
Auroras occur when particle radiation from the Sun hits Earth's upper atmosphere, making it glow in a greenish blue light. ESA astronaut Alexander Gerst has one of our planet's best views of this phenomenon, ...
Colliding atmospheres: Mars vs Comet Siding Spring
On October 19, 2014, Comet Siding Spring will pass by Mars only 132,000 km away—which would be like a comet passing about 1/3 of the distance between Earth and the Moon.
APL instrument to fly on first NASA-funded Virgin Galactic spaceflight
While Earth's upper atmosphere may soon be a destination for space tourists, scientists from the Johns Hopkins University Applied Physics Laboratory (APL) have set their sights on being among the first to ...
Earth's magnetic field is important for climate change at high altitudes
New research, published this week, has provided scientists with greater insight into the climatic changes happening in the upper atmosphere. Scientists found that changes in the Earth's magnetic field are ...
Venus Express gets ready to take the plunge
(Phys.org) —After eight years in orbit, ESA's Venus Express has completed routine science observations and is preparing for a daring plunge into the planet's hostile atmosphere.
MAVEN solar wind ion analyzer will look at key player in Mars atmosphere loss
This past November, NASA launched the Mars Atmosphere and Volatile Evolution (MAVEN) mission in the hope of understanding how and why the planet has been losing its atmosphere over billions of years.
Interesting prospects for Comet A1 Siding Spring versus the Martian atmosphere
It may be the chance of a lifetime for planetary science. This October, a comet will brush past a planet, giving scientists a chance to study how it possibly interacts with a planetary atmosphere.
Oxygen in exoplanet atmospheres could fool search for life
Oxygen is a signal of life on our own planet, but that's not necessarily the case elsewhere. Particularly when it comes to young planets, signs of oxygen do not necessarily indicate the presence of biological ...
Power-on and checkout of MAVEN's Electra Ultra High Frequency Transceiver
(Phys.org) —The team operating NASA's Mars Atmosphere and Volatile Evolution (MAVEN) mission successfully completed, on Feb. 19, 2014, the initial post-launch power-on and checkout of the spacecraft's Electra ...
MAVEN satellite looks for Mars' missing atmosphere
Ninety kilometers over our heads, the sky is glowing. During the day, the Sun turns the top of our sky into a sea of electrons. They flow over one another without friction, creating plasma. Radio waves that ...
Linear accelerator mimics incredibly energetic particles hitting atmosphere
(Phys.org) —In a SLAC test facility, scientists have set the stage for an experiment that mimics what happens when incredibly energetic particles hit our atmosphere. The players include the lab's historic ...
