Remote-sensing instrument for MAVEN spacecraft delivered

NASA has announced that things are coming together for its future Mars mission. NASA announced recently that the remote-sensing instrument designed to study Mars in the ultraviolet in an effort to discover how Mars might’ve lost its atmosphere has arrived at Lockheed Martin. Lockheed began the final assembly of the MAVEN spacecraft in September of this year.

The remote-sensing package consists of an Imaging Ultraviolet Spectrograph and the required control electronics box. That control electronics box is called the Remote Sensing Data Processing Unit. This particular sensor suite was designed and built at the University of Colorado laboratory for Atmospheric and Space Physics.

This particular sensing tool is designed to collect light, spread it out into different spectra, and record that spectra using imaging detectors. The Remote Sensing Data Processing Unit is the spectrograph’s main electronics box the controls the spectrograph and communicates with the spacecraft. That control box tells the Imaging Ultraviolet Spectrograph where to look and is the camera’s brain.

The MAVEN spacecraft is set to launch late next year with the goal of understanding the upper atmosphere of Mars. Scientists hope that MAVEN will help to determine the history of the loss of atmospheric gases to space helping to provide answers about the evolution of Mars’ climate.

Curiosity Mars rover finds radiation levels safe for humankind

Welcome back to Mars, ladies and gentlemen, as the NASA Curiosity mission continues its epic journey across the planet’s surface with a news note that they have found radiation levels totally safe for human beings. This finding is entirely encouraging for the future of Mars exploration as far as actually sending human beings there goes, and certainly doesn’t send a negative mark back on the possibility of us living there someday. Of course if you’re a fan of the original Total Recall, you don’t care one way or another simply for the safety of your eyeballs, but still.

Of special note here is the fact that this is the very first time radiation has been measured from the surface of another planet – besides Earth, that is. This is done with the rover’s RAD, or Radiation Assessment Detector, and has shown the radiation levels on the ground as rather similar to what the astronauts on the International Space Station experience daily. RAD Principal Investigator Don Hassler of the Southwest Research Institute’s Boulder, Colorado branch noted the findings as encouraging.

“We see a definite pattern related to the daily thermal tides of the atmosphere. The atmosphere provides a level of shielding, and so charged-particle radiation is less when the atmosphere is thicker. Overall, Mars’ atmosphere reduces the radiation dose compared to what we saw during the flight to Mars.” – Hassler

NASA has also added that the overall goal for this mission is to use 10 instruments on Curiosity “to assess whether areas inside Gale Crater ever offered a habitable environment for microbes.” This mission has been followed by tech blogs, science publications, and everywhere in-between simply because of the rarity of a Mars mission of this magnitude. We’ve seen tiny findings that mean little to us average citizens as well as lovely photos taken from the surface, perfectly suitable for wallpapers for your smartphone.

Above: The header image in this article shows five scoopfulls of material from what NASA describes as a patch of dusty sand called “Rocknest.” This set of five “bite-marks” shows how little NASA needs to analyze the surface – each mark is about 2 inches (5 centimeters) wide.

Have a peek at the timeline below of just a small sample of the goings-on around the Curiosity mission and consider the implications of the impact this NASA action is having on the future of space exploration. We’re hoping that science will prevail, allowing here more funding for NASA so that we can continue to expand our space-loving minds through the rest of our lifetimes and beyond – make it happen, public!

Curiosity rover finds radiation levels on Mars are safe for humans

Curiosity rover finds radiation levels on Mars are safe for humans

It’s been three months since NASA’s Curiosity rover set foot wheels down on Martian terrain, and now the space agency has divulged what it’s learned about radiation on Mars. Marking the first time radiation has been measured from the surface of another planet, preliminary data collected using the rover’s Radiation Assessment Detector (or RAD for short) revealed that levels on the ground are similar to what astronauts encounter on the International Space Station. What’s that mean for space travel? “The astronauts can live in this environment,” Don Hassler, principal investigator on Curiosity’s RAD hardware, said in a press conference. However, humans would still experience higher levels of radiation on the way to and from the red planet than on its surface. The results are encouraging, but they’re just one of many developments left before Homo sapiens set foot on Mars. For more details on the RAD’s findings, look below for the press release.

Google helps you kill time with 100,000 Stars experiment

If you’re bored and looking for something to do to kill a bit of time, Google has a new Chrome Experiment called 100,000 Stars. The idea is that it is a map of the galaxy of roughly 100,000 stars that are close to the earth on a cosmic scale. Close on a cosmic scale means within a few light years.

The project allows users to zoom in and out using the mouse or track pad on a notebook. You can get more information on stars, including their name, and you can see a digital version of the real star. It reminds me a little of that old Windows screen saver with starts zooming by.

The 100,000 Stars website uses WebGL, CSS3D, and Web Audio technologies. Music for the site is from Sam Hulick, who also composed music for video games such as Mass Effect. The service has a “take a tour” button that you can click it will take you wanted to work of some of the most prominent stars near us. As the word “space” implies, outer space is vast.

As it is right now, the furthest man-made object from our star is the Voyager probe, and it’s only 17 light hours away as it gets ready to leave our solar system. The nearest star system to our sun is Alpha Centauri, and it is 4.3 light-years away. I won’t say that the 100,000 Stars experiment is as cool some of the real images that NASA offers, but it’s up there with Google Space.

SpaceX founder Elon Musk talks about future of space flight

Entrepreneur Elon Musk has been around the block a few times. He helped start PayPal, the popular online payment system, and is even a founder of Tesla Motors. Musk’s most recent endeavor, however, is his space travel project, SpaceX, which recently completed its first successful supply mission to the International Space Station. Wired Magazine sat down with Musk and discussed original plans for SpaceX, the process of building and launching the rockets, and the possibility of a truly reusable spacecraft.

Musk mentioned that he thought about a manned mission to Mars in the early 2000s, and imagined building a small greenhouse on the surface of Mars, which would be packed with dehydrated nutrient gel that could be hydrated on landing. Musk said the rockets to get there would’ve cost $130 million alone, and he says the reason why there hasn’t been a manned mission to mars is because there isn’t cheap enough rocket technology.

However, Musk mentions that SpaceX is getting better at bringing the cost of rockets down significantly, almost by a factor of 10. Specifically, the company’s Dragon spacecraft, which was recently sent to the ISS, is actually an early prototype of the spacecraft that may one day head to Mars. Musk says that the current Dragon spacecraft wouldn’t have been able to land on Mars, but he says that the 2nd-generation capsule, which is expected to be completed in three years or so, is aiming to have that capability.

Musk also discusses reusable spacecrafts. He says “it’s the fundamental thing that’s necessary for humanity to become a space-faring civilization. America would never have been colonized if ships weren’t reusable.” He mentions that the Space Shuttle wasn’t actually truly reusable, since the main fuel tank was always thrown away and a new one was used for every launch. Musk is dedicated to building and improving on a truly reusable spacecraft, where every part of the ship can be reused, which Musk says will significantly reduce cost-per-launch factors.

Russian rocket explosion leaves new space junk in orbit

Russia has been facing some challenges in its space program over the last year. The most recent issue with Russia’s space program happened when one of its rockets failed to push its payload into the desired orbit in August. The rocket was a Briz-M rocket motor and is the third that has failed since 2007.

The latest Russian rocket failure left two fully fueled spacecraft stranded in orbit according to NASA. The Russian Briz-M upper stage was carrying the Telekom 3 and Express MD2 spacecraft. The rocket shut down shortly after the start of its third of four planned maneuvers on August 6.

When the rocket shut down it was in an orbit of roughly 165 miles x 3116 miles at an inclination of 49.9° relative to the equator. Both spacecraft on board were later autonomously released. However, when the third stage rocket engine became stranded in orbit, there were fears that the rocket could explode.

That fear proved true in the middle of October when the rocket stage exploded creating a massive new cloud of space debris that poses a threat to other orbiting satellites and could threaten the International Space Station. The explosion left behind a cloud of debris with more than 500 pieces. Even tiny pieces traveling at thousands of miles per hour in orbit pose a significant risk to satellites and for space travel. Scientists estimate that there are roughly 21,000 pieces of space junk larger than about 4 inches in orbit. There are roughly 500,000 pieces of debris between 0.4 and four-inches, and over 100 million pieces of junk in orbit smaller than 1 cm. Even those tiny pieces can cause catastrophe.
