McMurdo Panorama from Mars
31.10.2006

This was Spirit's view on Martian-day 1,000 of its 90-Martian-day mission. The robotic Spirit rover has stayed alive so long on Mars that it needed a place to wait out the cold and dim Martian winter.

International Space Station: Find the Astronaut

Where's the astronaut? Somewhere in this impressive array of International Space Station (ISS) hardware, astronaut Steve Bowen can be found upgrading and cleaning key parts of Earth's most prominent orbital outpost. Astronaut...

InSight's Final Selfie
3.11.2022

The Mars InSight lander returned its first image from the Red Planet's flat, equatorial Elysium Planitia after a successful touchdown on November 26, 2018. The history making mission to explore the martian Interior using Seismic investigations, geodesy, and heat transport has been operating for over 1,400 martian days or sols.

AZURE Vapor Tracers over Norway
7.04.2019

What's happening in the sky? The atmosphere over northern Norway appeared quite strange for about 30 minutes last Friday when colorful clouds, dots, and plumes suddenly appeared. The colors were actually created by the NASA-funded Auroral Zone Upwelling Rocket Experiment (AZURE) which dispersed gas tracers to probe winds in Earth's upper atmosphere.

An Active Sunspot Viewed Sideways
2.04.2007

Why are there dark spots on the sun? Although noted for thousands of years, sunspots have been known for decades to be regions of the Sun that are slightly depressed and cooled by the Sun's complex and changing magnetic field.

An X Class Flare Region on the Sun
5.11.2007

Why does the Sun flare? Unpredictably, our Sun unleashes tremendous flares expelling hot gas into the Solar System that can affect satellites, astronauts, and power grids on Earth. This close up of an active region on the Sun that produced a powerful X-class flare was captured by the orbiting TRACE satellite.

McCool Hill on Mars
14.03.2006

You can make it. Winter is rapidly advancing on the southern hemisphere on Mars, and the lack of sunlight could be dangerous unless you find a good place to hibernate. There it is ahead: McCool Hill.

Phoenix and the Holy Cow
11.11.2008

The northern Martian summer is waning. As predicted, a decline in daylight hours, deteriorating weather, and dust storms are preventing solar arrays on the Phoenix Mars Lander from providing power. Phoenix's last signal...

Fermi Epicyles: The Vela Pulsar s Path
4.05.2012

Exploring the cosmos at extreme energies, the Fermi Gamma-ray Space Telescope orbits planet Earth every 95 minutes. By design, it rocks to the north and then to the south on alternate orbits in order to survey the sky with its Large Area Telescope (LAT).

Survivor: NEAR Shoemaker On Asteroid Eros
4.03.2001

Not part of a television game series, the NEAR Shoemaker spacecraft survived its unprecedented landing on an on asteroid last month. As suggested in the illustration inset above, the car-sized probe likely rests gently on the tips of its solar panels having touched down under the influence of asteroid Eros' feeble gravity.
