Mars Pathfinder

It has been 20-years since the Mars Pathfinder with the little Sojourner rover was launched to Mars. The spacecraft landed successfully in an ancient flood plain called Ares Vallis or the valley of Ares. The landing site is in the northern hemisphere of Mars and is where Sojourner because the first rover to operate on Mars.

STEREO 10th Annaversary

Get your 3D glasses out if you can. Launched on 26 October 2006 the twin STEREO solar observers were just a few months into their flights when for a time they were situated at the proper distance from each other to allow us to see the stereoscopic view of the Sun.

Part of the NASA caption:

“This footage is from March and April 2007, when the small separation of the two spacecraft allowed a stereoscopic view of the sun similar to how human eyes perceive the world around us. These images were captured by STEREO in several wavelengths of extreme ultraviolet light which show different layers of the sun’s atmosphere. The number in the lower right of the video shows the wavelength of light measured in Angstroms.”

Earth 50 Years Ago

Earthfrommoon

50 years ago today the Lunar Orbiter 1 took the first picture of Earth from the moon. Lunar Orbiter 1 was launched on 10 August 1966 and returned 42 high-resolution and 187 medium-resolution frames were taken and transmitted to Earth covering over 5 million square kilometers of the Moon’s surface. This image was taken on 23 August 1966 at 16:35 GMT.

Sample 15415

Sample 15415 or the Genesis Rock was collected by Apollo 15 astronauts James Irwin and David Scott on the surface of the moon. The date was 01 August 1971 and it was the second EVA for the astronauts when Sample 15415 was collected from Spur crater.

The early idea was the Genesis Rock was lunar primordial crust, however it turn out not to be so. The rock is anorthosite.

Scientific data on Sample 15415.

The name Genesis Rock is stored at the Lunar Sample Laboratory Facility.

Here’s a written transcript of the astronaut radio transmissions at the time of the finding and below (should be) the audio file.

 

 

ISS Reaches Historic Milestone!

Congratulations to the International Space Station on completing 100,000 orbits since the station was launched on 20 Nov 1998. In the years since launch the station will have traveled around 2,643,342,240 miles, or roughly the distance between Earth and Neptune.

The event occurred at 06:10 UTC this morning 16 May 2016.
