Greetings on and all to the latest edition of carnival of Space. This week sees a great assortment of articles covering everything from rocket, to orbital space habitats to deep space. So grab your favorite beverage and settle in for a grand time!
We need to answer some fundamental questions regarding human life beyond the confines of our home planet. Will humans thrive under lunar or martian gravity? Can children be conceived in extraterrestrial environments? What is the safe threshold for human exposure to high-Z galactic cosmic rays (GCRs)?
To address these issues we might require a dedicated facility in Earth orbit.”
Welcome all to this edition of the Carnival of Space. here in the United States we are celebrating our Thanksgiving. This is a time of family, friends, good food and great news about space. So pull up a chair, grab a warm beverage and get an amazing start to the holiday season.
First up in this edition is Planetaria with a couple of great articles. The first covers the exoplanet discovery that could be a twin to Venus. They follow that up with an update on the Mars Curiosity rover as it prepares to study sand dunes.
Welcome to the Carnival of Space, Episode 429. The Carnival is your weekly dose of space related material from around the web. This week sees a series of articles from Universe Today, Chandra, The Huffington Post and more. Onward to the Carnival!
First up we have a Spanish article from Vega 0.0 discussing the differences in elemental particles.
Welcome to the Carnival of Space, Episode 424. Each week the Carnival brings you the latest and greatest space science articles to be found on this side of a Venusian sunset. Kick back, pull up a frothy beverage of your choice and enjoy this week’s reading selections.
And there you have the Carnival of Space for this week. Lots of good reading, great imagery and food for thought. Join us each week as a different website hosts the Carnival. Catch the next episode over at at Universe Today. And if you missed last week’s episode, you can read it at Next Big Future.
With all the new information streaming from New Horizons, this week’s Carnival of Space is very nearly all about Pluto. All the other Major planets have had their time in the media spotlight. Now Pluto takes center stage.
Welcome to Carnival of Space, Issue number 407. This Memorial Day edition is dedicated to everyone who served in their military, especially recognizing those who gave their lives in the defense of their nation. Our gratitude is with you all.
We start off this week’s Carnival with an article written in Spanish over at Vega 0.0. Goog Translate is a great tool for anyone who is a non-Spanish reader.
The Meridian Journal also has a pair of articles this week. The first an investigation into the discovery of possible sea salt on Europa. The second looks at the Northrop Gruman developed airplane designed to fly the skies of Venus.
Russia seems to be having numerous issues with spacecraft this year. After the dual loss of the Progress M-27M mission to the International Space Station (ISS) and the loss of a Proton-M rocket carrying MexSat-1, word comes from the space station that the currently berthed Progress M-26M is acting up.
Earlier today, engineers ordered the Progress spacecraft to fire its engines to provide a much needed boost to the ISS. This is done periodically to keep the station from falling into a low orbit that could result in the station re-entering the Earth’s atmosphere. When the command was given, the Progress refused to fire its engines. Controllers on the ground are currently troubleshooting the issue with hopes that a resolution may be found quickly. While the ISS is in no immediate danger, the lack of the orbital boost could become an issue.
Engineers currently suspect the main engine controller board but until they complete their analysis, the cannot be certain.
The loss of control of the Progress M-26M engines comes on the heals of some pretty challenging days. First Russia had issues with the launch of the Soyuz rocket with Progress M-27M on board. An anomaly with the third stage resulted in a mis-aligned orbit. Additionally, the Progress was left in an uncontrolled spin. The result was the total loss of the craft when it re-entered Earth’s atmosphere on May 5th.
That loss forced Russia to re-evaluate the upcoming manned Soyuz flight to the ISS. That launch has been postponed from May to July of this year to give engineers time to ascertain any threat to astronaut safety.
Just this morning, Russia suffered another launch setback with the failure of the third stage on a Proton-M rocket carrying Mexico’s next generation telecommunications satellite. That spacecraft (MexSat-1) would have provided secure communications channels for the Mexican government as well as public channels for video and audio feeds. The satellite was to provide new KU and L band communications.
While setback such as these due occur in spaceflight, this latest series cripples Russia’s ability to launch just about any payloads either manned or cargo. The bulk of their fleet is currently grounded. Options for cargo runs are limited. Orbital Sciences’ Antares vehicle is grounded due engine problems on their last flight resulting in the loss of the payload. Europe has ended the manufacture of their ATV cargo craft. Japanese HTVs may be possible if their timetable is compressed. SpaceX is the only cargo alternative still flying. No manned option exists.
With the triple loss that Russia has just experienced, spaceflight is in for a bumpy ride.
Greetings and welcome to another exciting edition of the Carnival of Space. Winter is in full swing with snow in most parts of the Norther Hemisphere. So grab a warn beverage and a blanket. Then snuggle in for a some amazing reading.
Everyday Spacer starts off this weeks edition with a great offer for free eBooks. Just fill out their survey and take your pick of great science fiction books. Well worth the visit.
Their second article looks at China’s plan for a new Long March 9 capable of lifting over 130 tons to LEO.
The final entry from NBF discusses the SpaceX satellite program in more detail. This one looks at the time it will take for the system to become operational and what this might mean for a communications network for Mars.
Robert Heinlein once said that if you can get to Earth orbit, you are halfway to anywhere. But how do you get from LEO to there? Next Big Future shares three articles that take a look at just that problem. Their set of news items focuses on engines designed for deep space:
The Meridian Journal features two articles on planetary happenings. First they take a look at something curious Curiosity has found on Mars. The follow that up with a look at dune sculpting on Saturn’s moon Titan:
