Latest on Strange Star

Hey Space Placers!

Here's an article on the very latest about the strange star that captured the world's attention when it was thought it could be surrounded by an alien megastructure.

We'll see what astronomers develop after they get this latest run of data.

Dark Energy Exist? Yes or No?

Hey Space Placers!

If you have been following Twitter or some of the major news outlets the last couple of days has seen some amazing headlines about the Universe.

There has been a paper published that dealt with the acceleration of the expansion of the Universe. The upshot of the paper as interpreted by readers is whether "Dark Energy" exists.

Read this article to get a good handle on the whole issue.

Bottom line is Dark Energy is still a VERY viable theory that is supported by multiple lines of evidence/data.

Mars Reconnaissance Orbiter views Schiaparelli landing site

Hey Space Placers!
It is beginning to look like ESA's  Schiaparelli Lander did not survive the landing attempt. Although data continues to be reviewed, photos of the area where it was to land show a new dark marking - crater - that could indicate a crash landing and explosion.

The other part of the mission, the Trace Gas Orbiter, is in orbit and working so this mission to the Red Planet is overall a success in terms of getting to Mars. 

Getting to Mars is HARD and the Red Planet is littered with crash sites from NASA, Russia and ESA to prove it. ESA's lander was an engineering test vehicle so it was successful in that valuable data was returned during the descent until contact was lost.

Humans will keep trying.......

ExoMars Update

Hey Space Placers!

Here is the latest from the European Space Agency (ESA) on their ExoMars mission which placed a new spacecraft in orbit and is awaiting the fate of their lander.

Time will tell if the lander survived.

Mars To Get New Visitors Today

Hey Space Placers!

Tune in today as the European Space Agency (ESA) prepares for its ExoMars spacecraft and Schiaparelli lander arrive at the Red Planet. 

If the landing is successful the Schiaparelli lander will join NASA's Curiosity and Opportunity Rovers on the surface of Mars and add to our knowledge of the planet.

Orbital ATK and NASA Wallops Flight Facility successfully launched the OA-5 resupply mission to the International Space Station on Monday night and here is my photo of the 1st stage rocket from 150 miles away.

Sky Guy Viewing ALERT! 10/17/16 Antares Rocket Launch

Hey Space Placers!

If you are in the DC, Maryland, Virginia (DMV) area or the U.S. East Coast, you may be able to see
tonight’s launch at 7:40 p.m. EDT of Orbital ATK’s sixth resupply mission, CRS-5, from NASA’s Wallops Flight Facility to the International Space Station (ISS) is a GO according to Keith Koehler, Wallops Flight Facility, Virginia

Wallops is Located on Virginia’s Eastern Shore so CRS-5’s launch and ascent to orbit will be visible to viewers in the DMV and along the U.S. East Coast. Using these maps  you can find your location and determine the best time to look for segments of the flight.

This is a return to flight for Orbital ATK’s Antares rocket which suffered an explosion during the CRS-3 launch from Wallops to ISS on October 28, 2014 . The rocket exploded just after liftoff and was completely destroyed along with the Cygnus spacecraft    carrying supplies and items destined to ISS. There was also damage to the launch facilities which have been repaired.

Orbital ATK and NASA determined that the launch failure was due to an issue with one of the AJ-26 engines’ turbo pump - there are two engines . The decision was made by Orbital ATK to switch to RD-181 engines for the Antares rocket which required design and manufacturing changes. The Antares rocket had to undergo certification tests and successfully conducted a static engine firing in May 2016

Last week the launch window had to be moved to Sunday because of Hurricane Nicole’s proximity to a ground tracking  station in Bermuda and then to Monday due to a faulty ground support equipment cable.

NASA TV coverage of the launch of the Orbital/ATK OA-5 Antares/Cygnus Mission to the ISS Starts at 6:45 p.m. EDT 

For the next few days you can see ISS in our skies. To get the sighting details for your location go to this NASA website .While there sign up for “ISS Sighting Alerts” so you will know when ISS is visible. 

ISS will be bright in the sky for these passes and if we are lucky we may even be able to see the Cygnus spacecraft “chasing” ISS. We won’t know until after launch if that is possible but I will update you.
