Apollo11

If you are an Apollo 11 nerd like me, you will want to check out a new website created by Ben Feist, a Canadian “software developer and spaceflight data visualization researcher working with NASA.”[1] The site called, “The First Landing on the Moon, Apollo 11, Real-Time Mission Experience,” is a treasure chest of audio clips, photos,…

Good-bye Opportunity

About three weeks ago I wrote about the Curiosity Rover that has been functioning on Mars for six and a half years. Today we say farewell to the Opportunity Rover (2004 – 2018) which was formally pronounced dead at a news conference yesterday. Thomas Zurbuchen, associate administrator of the Science Mission Directorate, said, “I’m standing…

TESS

If I were to go back to school to take more courses, I think I might take a few courses in orbital mathematics. The number of interesting orbits around masses in space has captured my imagination. Take for example the orbit of the latest NASA orbital space telescope, TESS (Transiting Exoplanet Survey Satellite). The following…

Jovian Skies

Juno is a spacecraft that was launched by NASA on August 5, 2011. After a journey of approximately 3 billion kilometers, Juno was inserted into an elliptical orbit around Jupiter on July 4, 2016 where it has been orbiting and carrying out its mission ever since. Its primary mission will last until July of 2018…

International Space Station

(Click on this thumbnail picture for a larger image) The International Space Station (ISS) flew over my home a few minutes ago. When you know where to look it is easy to pick out of a clear sky one or two hours before sunrise or one or two hours after sunset. The ISS circumnavigates our…

Saturn’s Polar Vortex

Cassini has begun grazing the rings of Saturn. This represents the next phase in the journey of NASA’s preeminent spacecraft. Around November 30, 2016, Cassini began orbits that swing close to the outer rings and give a great view of the north pole of the gas giant. The resulting images are spectacular and are a…

Cassini

Recently I wrote a sad lament for the Schiaparelli Lander, even as I praised those who had successfully inserted the Trace Gas Orbiter (TGO) into a near-perfect orbit around Mars. This orbiting communications relay and atmospheric laboratory will serve NASA scientists for the next several years and will eventually support a European Space Agency (ESA)…

A Robotic Spacecraft Dies

This week was supposed to be a week of good news for the Schiaparelli lander. It was expected that by this time, the Trace Gas Orbiter (TGO) would be relaying information from Schiaparelli to Earth and science experiments would be about to begin on the surface of Mars. The European Space Agency (ESA) did have…

Last Man on the Moon

“If you begin to think you’re something you’re not, you’re looking in the wrong mirror.” – Eugene Cernan I have been watching the Mark Craig directed documentary, Last Man on the Moon (2014). It is great educational entertainment for an Apollo junkie like me. It describes the career path of Eugene (Gene) Cernan as he…

Jupiter Through the Eyes of Juno

In August of 2011 a NASA rocket launch occurred. The rocket carried the Juno spacecraft on top of it and hurtled it out into space. Ever since then, Juno has been traveling toward Jupiter. In July of this year (July 4th to be precise), Juno will arrive and settle into an orbit around the…
