Blue (Full) Moon Friday UPDATED

Hey Space Placers!

Be sure to get out tonight (Friday 7/31) to see the second Full Moon of July. Called a Blue Moon as explained in this article this happens about once every 2 1/2 years.

Here's my pic:



For U.S. observers the International Space Station is starting a series of great passes. Go to Spot the Station to register your location so you can see ISS flyover. Quite the sight.

Here's my FIRST telescope pic (movie) of ISS - look quickly!

Red Arcs on A Saturn Moon???

Hey Space Placers!

The solar system continues to amaze:

NASA JPL
Check out the RED colored arcs in the photo of Tethys, an icy moon of Saturn. The photo was obtained by the Cassini spacecraft that has been at Saturn for a decade. The photos were taken in April 2015.

Mission scientists presently do not know what is causing the arcs but it is possible that they are chemical compounds or some kind of outgassing.

It has been quite the year in solar system exploration and it is far from done.

Stay tuned.....

Update on The Other Dwarf Planet - Ceres

Hey Space Placers!

Here's the latest on NASA's other 'dwarf planet' mission, Dawn. Instead of Pluto this mission has been exploring the largest body in the asteroid belt between Mars and Jupiter, Ceres.

Mission scientists have been able to make the best maps to date of Ceres and have started naming features seen on this fascinating world.

NASA

The Dawn spacecraft is slowly decreasing its altitude around Ceres and will provide even greater details as it achieves its final orbit.

Just Be Amazed At the View

Hey Space Placers!

NASA SWRI JHUAPL

BEHOLD PLUTO! AN icon in the making, this image was taken by New Horizons 7 hours following the July 14th flyby and released at today's press conference.  The distant Sun backlights Pluto and allowed the spacecraft to photograph the hazy atmosphere. Details like two distinct layers can be seen and additional data and analysis will provide more information on the distant world.

We also got to see flowing Nitrogen ice (!) on the surface acting just as glaciers on Earth.....wow.

NASA SWRI JHUAPL

The New Horizons team will have more for us to feat our eyes on in the coming weeks.

Stay tuned.

ISS, Exoplanets Update

Hey Space Placers!

We now have 6 astronauts aboard the International Space Station (ISS) as 3 new astronauts of Expedition 44 joined the 3 already on board. The Russian Soyuz successfully rendezvoused with ISS just after midnight EDT on 7/23/15.

NASA's exoplanet hunting spacecraft Kepler was the topic of a news conference on 7/23/15. It was announced that Kepler had "confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another “Earth.” 
"The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone -- the area around a star where liquid water could pool on the surface of an orbiting planet -- of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030."

The OTHER Dwarf Planet Mission - Dawn at Ceres

Hey Space Placers!

We have another dwarf planet mission besides New Horizons going on in the solar system - Dawn at Ceres. This mission is orbiting Ceres, the largest object in the asteroid belt located between the orbits of Mars and Jupiter.

I have blogged about the 'bright spots' at Ceres which has captivated those who have seen them and are following the mission.

NASA
In an article published today in Nature Ceres' bright spots are discussed or more specifically, a mysterious haze that has been detected above them.

Great stuff.....

Our solar system continues to amaze us.

I Photographed Pluto

Hey Space Placers!

A busy couple of days with Pluto and I will have more tomorrow BUT I had to share the following with you.


I have ALWAYS wanted to photograph Pluto. It is A CHALLENGE as Pluto is faint and is currently amongst the dense star fields of the Milky Way in Sagittarius.

I took one photo on the 15th and a second on the 16th, almost two days a part. Using a finder chart from Sky and Telescope I was able to pinpoint the elusive and wonderful world as you can see here:

Identifying Pluto on these images gave me a sense of what Clyde Tombaugh had to do to discover Pluto in 1930. He used a device called a Blink Comparator to watch for changes in the star field of two different photographs whereas I did not. I had a finder chart for Pluto which he did not.

It is not an easy thing to do finding Pluto. Even the New Horizons team had to make sure they were on target with their spacecraft.

Maybe someday I will see this fabulous world in the eyepiece of a telescope - that would be something.

Pluto Flyby 1st Images - WOW Oh WOW!

Hey Space Placers!

BEHOLD PLUTO

NASA SWRI JHUAPL
In this just released photo taken by the New Horizons spacecraft during its 7-14-15 flyby of Pluto you can see mountains made of ice that are 11,000 feet high!

Pluto also lacks impact craters that you would expect for a 4.5 billion year old world. The lack of craters means that Pluto is a geologically active world that "refreshes" it surface. This is an entirely unexpected discovery. 

BEHOLD CHARON

NASA SWRI JHUAPL


Charon, the largest moon of Pluto, has a surprisingly young surface devoid of large numbers of impact craters just like the Pluto image.

The "gouge" in the upper right section of Charon is a canyon over 4 miles deep and we can actually see through one part of it into space itself. Ridges, the dark pole, oh so much going on here!

More images and data will be coming in and the next release should be this Friday. 

This is JUST STARTING as there are 16 months of data and pics headed our way.

Stay tuned to be amazed.....

New Horizons NOMINAL (OK)

Hey Space Placers!

7-14-15

A few haunting seconds after the signal from the New Horizons spacecraft was supposed to be heard, it finally phoned home a little after 8:52 p.m. EDT. Transmitted over 4.5 hours earlier the radio signal came in to the Mission Operations Room at Johns Hopkins Applied Physics Lab having covered 3 billion miles of space.

As the telemetry provided the health of the spacecraft the wonderful word 'nominal' was used over and over to describe each of the systems. In the end, 'The spacecraft is healthy' was the assessment given to New Horizons - the piano sized spacecraft that had survived the close approach to the last planet to be explored up close and personal.

New Horizons has been acquiring data all day and will be sending it back over the next 16 months.
We should get our first look of Pluto at closest approach, a shade under 7,800 miles, tomorrow. I am sure this will be something to see.

Here is what Pluto and its biggest moon Charon might look like on the dark side of Pluto:

Maybe we will see such an image. I know we will be amazed by what we do see!

Bye Bye Pluto

Hey Space Placers!

Here is the last picture taken by New Horizons on 7-13-15 prior to today's 7:49 a.m. EDT closest point of approach (see my previous blogs).

NASA SWRI JHUAPL
We will not know for certain if the New Horizons spacecraft successfully completed its scheduled flyby of Pluto until about 9 p.m. EDT tonight - 7-14-15. That is when the "thumbs up" signal scheduled for transmission at approximately 4:30 p.m. EDT will be received.

It will have taken 4 1/2 hours for that radio signal to reach Earth 3+ billion miles away traveling at the speed of light - 186,000 miles per second.  The spacecraft has maintained radio silence during the flyby in order to concentrate on data acquisition. It will take 16 months for all of the flyby data to be transmitted and received by Earth. The transmission rate is only 2,000 bits per second - painfully slow due to the immense distance involved.

We will hopefully receive the first flyby photo tomorrow, 7-15-15.

Pluto is now a WORLD we have visited for the first time in history with a robotic emissary...something that will never happen again. It is not likely we will be this way again any time soon.

New Horizons is now leaving Pluto behind and perhaps heading to a new mission to visit another world if approved.

How Big Is Pluto Is FINALLY Settled

Hey Space Placers!

New Horizons has FINALLY settled a most basic question of the deposed 9th planet of the solar system  - "How big is Pluto?"



The data returned from 3 billion miles away says Pluto checks in at 1,473 miles (2,370 kilometers) in diameter.

 This makes Pluto the largest of the four other dwarf planets known to exist beyond the orbit of Pluto.

Be sure to tune in tomorrow morning for the flyby.

NASA Selects 1st Astronauts For Commercial Crew Program

Hey Space Placers!

A temporary break from New Horizons to Pluto today.

NASA
NASA has announced the 1st four astronauts to be assigned to the Commercial Crew Program to fly the Boeing CST-100 and SpaceX Crew Dragon spacecraft to the International Space Station beginning in 2017. Be sure to watch the video to hear Bob, Eric, Doug and Sunni's reaction to their historic assignment.

All 4 are veteran astronauts having flown in space previously and will use their collective experience to help finalize the spacecraft and prepare and train for their flights. This marks the first flight assignment for U.S. astronauts to fly into space on U.S. spacecraft since the space shuttle was retired in 2011.

Boeing's CST-100 is slated for the 1st flight.

This is a VERY big step indeed for NASA's return to using American hardware for manned spaceflight.

UPDATED: New Horizon Pluto Spacecraft Suffers Glitch

Hey Space Placers!

NASA
UPDATE AS OF 7/6/15

NASA has announced that New Horizons will re-commence science operations of July 7 as the cause of the glitch tot he spacecraft was not hardware or software related. It was a timing error in commands uploaded for the 7/14/15 flyby.

NASA will hold a press conference today 7/6/15 at 3 pm EDT.

The REALLY good news is that this did not happen days from now. All of the science lost while New Horizons was in safe mode will be obtained. No more commands are scheduled for uploading to the spacecraft prior to flyby.

Getting REALLY excited.

Sky Guy in VA

-------------------------------------------------------------------------------------




NASA's New Horizons spacecraft that is less than 10 days from its historic July 14th flyby of distant Pluto has suspended science operations due to a glitch.

NASA and the New Horizons' team has set up an anomaly board to determine what caused the spacecraft to lose communications with Earth and go into 'Safe Mode'.

The team has stated that it expects to resume science operations within the few days. There has been no update since the initial announcement.

We will keep you informed.

Happy Birthday Crab Nebula (And America)

Hey Space Placers!

July 4th, 1054 saw a "guest star" appear near Taurus the Bull, as noted by Chinese and American SW star gazers.

Modern telescopes checking the position of this historical observation would discover the "Crab Nebula":


To see this very bright guest star must have been something to see - we are overdue to see one in the Milky Way Galaxy.

I hope everyone in America has a safe and fun 4th of July.
