“Upstate NY Stargazing In September” Article Posted To newyorkupstate.com And syracuse.com

Greetings, fellow astrophiles!

With the summer nearly over and long nights replaced by early school bus mornings, the UNY Stargazing series has returned to its regularly-scheduled monthly publishing.

The latest article in the Upstate NY Stargazing series, “Upstate NY stargazing in September: Cassini’s end and morning planet delights,” has just been posted to newyorkupstate.com and syracuse.com.

The Great American Eclipse for 2017 has come and gone without major reported inconvenience to the cities that ended up hosting large groups. This is good news for Western and Upstate New York, as we will be participants in the observation of totality on April 8, 2024 and have to contend with potential crowds on top of whatever weather early April brings that year. In the meantime, if you still have your eclipse glasses, you can give others an opportunity to enjoy upcoming total eclipses in South America and Asia in 2019. Consider donating your glasses to the great outreach organization Astronomers Without Borders – see the link for all the details.

* It is a busy month for amateur astronomy, with Jupiter getting very close to being un-observable until December (so catch those photons now), Cassini about to take a serious plunge into Saturn, and Mercury, Venus, and Mars doing a wonderful dance in the pre-sunrise skies all month. Try to catch the days shown below (and see the article for more details)!

* The constellation of the month is Draco – and with just one more circumpolar constellation to go, we’re two months away from explaining just what that means!

NASA Space Place – Twenty Years Ago on Mars…

Poster’s Note: One of the many under-appreciated aspects of NASA is the extent to which it publishes quality science content for children and Ph.D.’s alike. NASA Space Place has been providing general audience articles for quite some time that are freely available for download and republishing. Your tax dollars help promote science! The following article was provided for reprinting in July, 2017.

2013february2_spaceplaceOn July 4, 1997, NASA’s Mars Pathfinder landed on the surface of Mars. It landed in an ancient flood plain that is now dry and covered with rocks. Pathfinder’s mission was to study the Martian climate, atmosphere and geology. At the same time, the mission was also testing lots of new technologies.

For example, the Pathfinder mission tried a brand-new way of landing on Mars. After speeding into the Martian atmosphere, Pathfinder used a parachute to slow down and drift toward the surface of the Red Planet. Before landing, Pathfinder inflated huge airbags around itself. The spacecraft released its parachute and dropped to the ground, bouncing on its airbags about 15 times. After Pathfinder came to a stop, the airbags deflated.

Before Pathfinder, spacecraft had to use lots of fuel to slow down for a safe landing on another planet. Pathfinder’s airbags allowed engineers to use and store less fuel for the landing. This made the mission less expensive. After seeing the successful Pathfinder landing, future missions used this airbag technique, too!

Pathfinder had two parts: a lander that stayed in one place, and a wheeled rover that could move around. The Pathfinder lander had special instruments to study Martian weather. These instruments measured air temperature, pressure and winds. The measurements helped us better understand the climate of Mars.

The lander also had a camera for taking images of the Martian landscape. The lander sent back more than 16,000 pictures of Mars. Its last signal was sent to Earth on Sept. 27, 1997. The Pathfinder lander was renamed the Carl Sagan Memorial Station. Carl Sagan was a well-known astronomer and science educator.

Pathfinder also carried the very first rover to Mars. This remotely-controlled rover was about the size of a microwave oven and was called Sojourner. It was named to honor Sojourner Truth, who fought for African-American and women’s rights. Two days after Pathfinder landed, Sojourner rolled onto the surface of Mars. Sojourner gathered data on Martian rocks and soil. The rover also carried cameras. In the three months that Sojourner operated on Mars, the rover took more than 550 photos!

Pathfinder helped us learn how to better design missions to Mars. It gave us valuable new information on the Martian climate and surface. Together, these things helped lay the groundwork for future missions to Mars.
