Captain Rick doing some [un] common sense thinking … It is possible that Mars was once a thriving planet that grew too cold to sustain life. This excellent post by a fellow WordPresser presents interesting thinking concerning possible past life on Mars based on photos captured by the Martian rover.

I have long thought that as our sun cools, its outer planets grow cold and loose ability to support life. It is possible that before life on an outer planet becomes extinct, its inhabitants become capable of exploring a warmer planet closer to the sun and begin a migration process.
Perhaps past inhabitants of Mars became space pioneers and ventured to earth to begin new live. Perhaps one day soon earthlings will be able to travel to Mars and take a closer look at where their distant ancestors lived. Perhaps a long time from now earthlings will venture to Venus as it cools and earth grows too cold to support life.
Thinking is a wonderful gift we should all exercise more often.

We can all probably agree that Mars is one of the most fascinating planets –besides Earth– in our solar system. We have learned so much about the red planet that we changed our opinion about everything we previously thought about Mars. Researchers finally know that Mars wasn’t always a desolate and inhospitable place. In fact, millions of years ago, the red planet may have been eerily similar to Earth.

In recent years, scientists have found out that Mars has liquid water flowing on its surface, a discovery that drastically changed everything we ever knew about Mars. The fact that NASA knows there is water on Mars means that they can pick out the best places to search for primitive life. If there is water, then perhaps there might be life on Mars.


But not only did we find out that Mars has liquid water, NASA…

Captain Rick: The International Space Station has a new camera that broadcasts live video streaming of earth as it orbits every 90 minutes. This is amazing new technology that was made possible by a recent supply mission by SpaceX’s Dragon supply ship. I captured this stunning image looking south over the Baja of Mexico as the ISS flew over Los Angeles just after 3 PM this afternoon.

Info on SpaceX’s Dragon … a private commercial space vehicle that takes over for the retired Space Shuttle

Dragon is a partially reusable spacecraft developed by SpaceX, an American private space transportation company based in Hawthorne, California. Dragon is launched into space by the SpaceX Falcon 9 two-stage-to-orbit launch vehicle, and is capable of both manned and robotic operation.

During its uncrewed maiden flight in December 2010, Dragon became the first commercially built and operated spacecraft to be recovered successfully from orbit. On 25 May 2012, an uncrewed variant of Dragon became the first commercial spacecraft to successfully rendezvous with and be attached to the International Space Station (ISS). SpaceX is contracted to deliver cargo to the ISS under NASA’s Commercial Resupply Services program, and Dragon began regular cargo flights in October 2012.

SpaceX is additionally developing a crewed variant of the Dragon called DragonRider. DragonRider will be able to carry up to seven astronauts, or some combination of crew and cargo, to and from low Earth orbit. SpaceX has received several U.S. Government contracts to develop its crewed variant, including a Commercial Crew Development 2 (CCDev 2)-funded Space Act Agreement in April 2011, and a Commercial Crew integrated Capability (CCiCap)-funded space act agreement in August 2012. The spacecraft’s heat shield is furthermore designed to withstand Earth re-entry velocities from potential Lunar and Martian spaceflights.

International Space Station


Captain Rick: Astronauts onboard the International Space Station restored the cool via space walks in December 2013.

As an engineer and lifelong follower of NASA, the Space Shuttle and the International Space Station (ISS) programs, I am compelled to report on this remarkable event. I was fortunate to personally witness a Space Shuttle launch from Cape Kennedy in the early 1980s. The shaking of the ground and thundering across the sky was the most awesome experience of power that I have ever witnessed.

I created an ‘Atridim Widescreen’ photo crop of a recent space walk (compliments of a NASA high definition original) for full screen viewing enjoyment on your HDTV or widescreen computer monitor.

Details of the recent Space Walk:

Expedition 38 Flight Engineers Rick Mastracchio and Mike Hopkins wrapped up a 5-hour, 28-minute spacewalk outside the International Space Station at 12:29 p.m. EST Saturday, December 21, 2013, completing the first in a series of excursions aimed at replacing a degraded ammonia pump module associated with one of the station’s two external cooling loops that keeps both internal and external equipment cool.

On Sunday, Dec. 22, NASA astronaut Mike Hopkins tweeted of Saturday’s spacewalk, saying, "Wow… can’t believe that is me yesterday. Wish I could find the words to describe the experience, truly amazing."

A second spacewalk to install a replacement pump module occurred on Dec. 24, 2013. NASA astronaut Mike Hopkins, Expedition 38 Flight Engineer, participates in the second of two spacewalks, spread over a four-day period, which were designed to allow the crew to change out a faulty water pump on the exterior of the Earth-orbiting International Space Station. He was joined on both spacewalks by NASA astronaut Rick Mastracchio, whose image shows up in Hopkins’ helmet visor.

I subscribe to NASA’s ISS ‘Spot the Station’ email alerts and enjoy watching the ISS frequently pass over my Arizona Oasis during the early dawn or late dusk sky, when it is the brightest and fastest moving ‘star’ across the sky. It travels at 17,000 mph at an altitude of 265 miles. If you have not seen the ISS soar overhead…you have missed a wonderful spectacle.

Have you seen the ISS race across the sky?


Captain Rick: The International Space Station has experienced a failure in one of two cooling systems. NASA describes the situation as “urgent” but not “life threatening”. Its crew of 6 might have to evacuate if cooling capacity is not restored soon.

The ISS is the size of a football field, orbiting earth at 265 miles up, traveling at a speed of 17,000 mph. As an avid follower of the ISS since its first components were launched into orbit by a NASA Space Shuttle in 1998, I enjoy watching it pass over my home in Gilbert, Arizona every chance I get. The ISS is only visible during a short time frame before sunrise or after sunset when the sky is dark and the ISS is illuminated by the sun’s rays. A good sighting only happens once or twice a month for most locations on earth that lie within 55 degrees north and south of the equator. Last evening, the ISS’s rare pass overhead carried special significance. As I watched it zoom across the sky and vanish into earths shadow four minutes later, I realized that on board were six crew members that were facing a serious situation.


Why does the ISS need cooling when the temp in space runs –454F (-270C)?

The International Space Station, with an acre of solar panels, generates between 75 and 90 kilowatts of power. This power is used by the ISS’s systems, from life support, to storage freezers, to various lab experiments that are dotted throughout the interior. This generates a lot of waste heat — heat that has to be vented into space. To do this, the ISS has a cooling system — essentially a pump, a radiator, and some pipes filled with ammonia — that ferries heat from inside to outside, where the chills of outer space (-270 Celsius or -454 Fahrenheit) quickly dispose of the heat.

There are two cooling loops — Loop-A and Loop-B — and for some reason Loop-A failed late on Wednesday. Usually both systems work in concert to keep the ISS and its various systems cooled, but now Loop-B must bear all of the load. To compensate, some non-critical systems and science experiments (the Japanese Kibo lab, the European Columbus lab) have been disabled. Life support, storage freezers, and other systems that are of vital importance are still up and running.

What is being done to fix this urgent problem?

NASA is currently working around the clock to determine what’s wrong with Loop-A, and how to fix it. So far, it sounds like a flow control valve malfunctioned, causing an anomalous temperature imbalance, which triggered an automatic shutdown when the system reached a preset threshold temperature. The fix might be as simple as uploading some new management software for the valve, or it may require a risky spacewalk to replace a component. Spacewalks have been banned for a while due to 2 cups of water leaking into the helmet of a previous spacewalker.

What if the problem can not be fixed with available parts onboard or via a software patch?

The worst-case scenario is that Loop-B fails before they can fix Loop-A: this would require evacuation of the 6 crew members on board.  There are always enough Soyuz capsules attached to the ISS to ensure that everyone on board has a ride back to Earth. I have hope that the many great minds working on this problem will find a fix and save the great works of the International Space Station. I see the ISS as one of the few expenditures of big money that has been constructive in bringing nations together for a great common research cause (about $150 billion so far, including…NASA: $70 billon, Russia: $12 billon, Europe: $5 billion, Japan: $5 billion, Canada: $2 billion).

NASA email alerts of when the ISS will pass over your area

Captain Rick: The International Space Station is the brightest, fastest moving object in the sky just before dawn or after sunset for those in the perfect, ever-changing location. The ISS, the size of a football field, is the largest structure in earth orbit. The ISS is orbiting about 250 miles up and traveling at a speed of over 17,000 mph. It travels from the western to eastern horizon in less than 10 minutes. It appears to move faster than a commercial plane at cruising altitude and brighter than any star. Its an awesome spectacle that can be observed by almost anyone on earth at the right time.

The ISS revolves around the earth every 93 minutes. It makes 15 revolutions per day. Each pass moves about 1500 miles to the west, due to earths eastward rotation.  Its path follows a sine wave on a ‘flat map’, as shown below, because its orbit is skewed at an angle with reference to earth’s equator. This allows the ISS to fly over areas between 52 degrees latitude north or south of the equator, making it accessible from Russian launch sites, which are farther north than those in the US.


View the ISS: To view the ISS, it must pass over your area about 1 hour before sunrise or 1 hour after sunset, so that the sun’s rays illuminate it against a dark night sky. Most places on earth will experience one or more good viewings of the ISS each month. The best view of the ISS happens when it passes directly overhead (its closest encounter), during the pre-sunrise/post-sunset window. This is rare occurrence for any given spot on earth…so when it happens in your area, you must be prepared.

Captain Rick’s eyewitness sighting: I witnessed the ISS race over Gilbert, Arizona at 4:48 AM a few days ago. It was the first time I had ever seen it. I was amazed by its speed and brightness. It out-raced and out-shined anything in the sky. The ISS is indeed an experience that everyone should witness.  It only spends a few minutes traveling from one horizon to the other. I caution…to see it, you have to be prepared with its timing and trajectory. I have provided some great tools to help you capture a glimpse of the ISS as it streaks over your area…

Captain Rick: The Space Shuttle is history, but not the excitement of new space machines. This launch of the massive 3-booster Delta-IV Heavy rocket, with the capability of placing a 25-ton payload into orbit, introduces the ability to visually identify the make and model of a vehicle from 250 miles up. 

Remember those movies where satellites could zoom in and see what is going on down on earth? It has all been science fiction…until now.  If all goes well, that fiction will take a bold step towards reality with this launch.


Today’s inspiring launch was the second for this new 232-foot-tall monster rocket machine from Vandenberg Air Force Base in California. The first was in January 2011. A new era has begun.

Details about the satellite, designated NROL-65, are classified. The three-booster Delta-IV rocket used to send it aloft Wednesday is the heaviest in the U.S. inventory, capable of putting a 25-ton payload into low Earth orbit.

Todays launch was one of two launches the top-secret National Reconnaissance Office has on the books for late 2013.

The payload in Wednesday’s launch is thought to be a $1-billion high-powered spy satellite capable of snapping pictures detailed enough to distinguish the make and model of an automobile hundreds of miles below.

The 232-foot-tall booster was developed by the U.S. Air Force and the United Launch Alliance, a joint venture between aerospace giants Boeing and Lockheed Martin.
