Sometimes it helps to look back and see how far we’ve come. The National Geographic has a nice pictorial display of major milestones in space photography. All the famous and not so famous images from space photography collected into a display!
Scientists at the European Southern Observatory have discovered the farthest galaxy known – 13 billion light years away! The galaxy is in essence a baby picture of a newly formed galaxy 13 billion years ago. It would have been the first formed galaxy after the Big Bang. It was found using a pretty impressive system of refactoring Earth observation through a galaxy cluster that acts as a powerful zoom lens due to its density.
I promised myself I wouldn’t make the obvious joke here, but I just can’t help it – now that’s some remote sensing!!
Our reader Michelle sent us a quick email to let us know that the USGS has announced that Landsat 5 resumed imaging as of January 10th. Landsat 5 has been experiencing problems with its batteries, and the Landsat team has come up with a new procedure for charging the batteries to try to maintain a safe power balance. No new data has yet been released, but should start becoming available as it is processed.
It is just amazing how well Landsat 5 has lasted (It made its 125,000 orbit back in September) and the incredible efforts by the Landsat team to keep it and Landsat 7 up and running for image collection, and hopefully the good news will continue. If you haven’t checked out the Landsat Project website, you should definitely take a few minutes and browse around through the project history, image gallery, resources and other information on this amazing 35-year remote sensing effort.
The Messenger spacecraft is reporting back the first high resolution images of Mercury taken since the ’70′s. They’re over 3x better than anything we had before. The images are pretty fascinating!
Ok, so it was a bad joke. Apparently, the Earth is just barely big enough to support life. The National Geographic is reporting this new research that says the Earth is barely big enough for plate tectonics, which are critical to CO2 formation and maintenance, which in turn is critical for life. It’s an interesting finding, because it means that if we want to look for a place in outer space that could hold similar conditions as Earth, we need to be looking for much larger, rockier places. Maybe the Earth is a one in a gazillion place?
National Geographic is reporting that we can expect a season of intense solar flares for the next few weeks and months. This is all part of a normal 11 year cycle in solar flare activity, but it can lead to some distinct headaches in our tech heavy world. As the article notes, this is the first cycle where GPS is widespread – and GPS is one of the systems most easily affected by solar flares. It will be interesting to see how much impact these flares have on our day to day lives, particularly in the geospatial community. So, for the next few weeks/months, if you’re doing GPS field work, you might want to bring a book!
Odyssey Moon, a company based on the Isle of Man, on Thursday became the first team officially entered in the Google-sponsored Lunar X Prize, which is offering a total of $30 million in prize money to support a lunar mission. The $20 million first prize will be for the team that can fly a spacecraft to the moon, operate a robotic rover, and then transmit a Mooncast back to Earth, all before December 31, 2012. After that, the prize money starts dropping. There is also a $5 million second prize, and $5 million in bonus prizes for additional tasks completed by the rover on the Moon. Funding and policy issues related to government-sponsored space exploration are opening the door for even more private involvement in space, and it may be that the next moon landing won’t be made by China or Japan or the US, but a private company. Several hundred teams have already made inquiries about entering the competition, so Odyssey Moon may only be the first of many.
At the 4th meeting of the Group on Earth Observations (GEO) that was just held in Cape Town, South Africa, China and Brazil issued a joint statement announcing a plan to provide Africa with free satellite imagery. Ground stations within the African continent will be set up to receive the data from the China-Brazil Earth Resources Satellite (CBERS) Program. The first station, in South Africa, will begin receiving imagery shortly, with others to begin operating in 2008. Researchers and scholars in many countries have relied on Landsat and other US satellites for environmental remote sensing data in the past, but this project shows that increasingly other countries and regions are stepping up and working to continue to provide the data that is needed to understand the impacts of climate issues and even shorter-terms events like natural disasters on the environment.
The European Space Agency’s comet satellite completed it’s second swing around Earth on the 13th of this month. The swing is necessary to gain speed for it’s deep space mission. Along the way, the satellite pointed it’s cameras at the Earth to capture a few snapshots. Most of them center on Antarctica.
Japan’s lunar explorer Kaguya, in orbit around the moon, has sent back the world’s first worldâ€™s first high-definition video of the moon’s surface. Both Japan and China currently have satellites in orbit around the moon, and there has been talk of a new space race between the two countries, although each government denies it.
