NASA May Have Discovered Flowing Water on Mars Dark, finger-like features appear and extend down some Martian slopes during late spring through summer, fade in winter, and return during the next spring. Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in the middle latitudes of Mars' southern hemisphere.
Pluto may have been downsized in 2006, but it's still living large, moon wise: A fourth moon has been discovered orbiting the dwarf planet.
Dawn spacecraft now orbits asteroid Vesta - After almost 4 years of space travel, the Dawn spacecraft successfully entered orbit around Vesta, an Arizona sized rock. Dawn tweets, takes pictures, and there is a Vesta Fiesta party to celebrate. After hanging out at Vesta for a year, Dawn will head off to visit the Ceres asteroid next, a three year trip. Amazing achievement of engineering, innovation and accuracy.
On July 5th the SOlar and Heliospheric Observatory (SOHO) captured video of a comet, known as a sungrazer, in route to collide with our star. SOHO is equipped with an occluding coronograph that blocks direct sunlight and reveals the corona, but also prevents direct study of the terminal impact of sungrazers. But on July 6th, with the help of the Solar Dynamics Observatory (SDO), astronomers were able to observe the comet (slyt) streaking in front of the surface of the sun for the first time in history. It likely disintegrated before impact due to extreme heat and radiation.
The Space Shuttle Atlantis, STS-135, is scheduled to lift off this morning from Kennedy Space Center. The time was originally scheduled for 11:26 AM EDT, but that has been pushed back, despite "no technical concerns and... weather is a 'go'." Astronauts aboard are Commander Chris Ferguson, Pilot Doug Hurley, and Mission Specialists Sandy Magnus and Rex Walheim. Watch live coverage, with some archival footage, on NASA's Ustream or on NASA.gov. NASA has provided countdown highlights of the day to get you up to speed. Read NASA's feed on Twitter. At the time of this post's writing, the countdown clock is on a scheduled hold with 9 minutes to go. Previously, STS-134, on the Blue.
On May 16, 2011, after one scrubbed attempt, the space shuttle Endeavour set off on her final mission, STS-134. Shuttle commander Mark Kelly had this to say after receiving a "go" from the launch poll:
On this final flight of space shuttle Endeavour, we want to thank all the tens of thousands of dedicated employees that have put their hands on this incredible ship and dedicated their lives to the space shuttle program. As Americans, we Endeavour to build a better life than the generation before, and we Endeavour to be a united nation. In these efforts, we are often tested. This mission represents the power of teamwork, commitment, and exploration. It is in the DNA of our great country to reach for the stars and explore; we must not stop. To all the millions watching today, including our spouses, children, family, and friends, we thank you for your support.You've seen launches before, but NASA has uploaded a whole slew of angles that will truly amaze: Witness 4.4 million pounds of shuttle, fuel, and rocket boosters "twang" a full 18 inches as the main engines ignite. 1.2 million pounds of thrust push against a locked down stack, waiting for the solid rocket boosters to ignite. (The SRBs bring the total to 7 million lbs of thrust, enough to break all that binds her to the pad.) OTV Camera 71, a fantastic, short close-up. UCS-15 (TV-21A) provides a dead-on, close up shot of the launch. The South Beach Tracker shot offers a fantastic view as well. From 3.1 miles away at the Press Site, note the ~11 second delay before the piercing sound of the SRBs hits. And just released today, fantastic footage from the solid rocket boosters, including their trip to splashdown in the Atlantic ocean from 30 miles up. And finally, the classic NASA view, with some great data overlays by Spacevidcast. [more inside]
50 years ago today, on May 25 1961, US President John F. Kennedy decided "...this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." Eight years later the Apollo program fulfilled the task, leaving the world with a legacy that includes advances in computers and communciation, lessons in managing complex projects, technological innovations and new views of the Earth.

Croatian software developer and amateur image processor Gordan Ugarković takes images from NASA's unmanned space probes released to the Planetary Data System, splices them together and tweaks the colors, sometimes combining higher resolution black and white images with color images, sometimes recreating what the object would look like in natural color (ie, in visible wavelengths, from images taken in multiple wavelengths), sometimes heightening the contrast to bring out detail.

Challenger . . . . go with throttle up. Twenty-five years ago today the U.S. Space Shuttle Challenger exploded 73 seconds into the 25th space shuttle flight. The reports (pdf) tell us of O-Ring failures. Today, we remember one of the most tragic days in the history of the U.S. manned spaceflight program. Today, January 28, 2011, we remember: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe.
The Voyager I spacecraft, 33 years into its mission, "has outrun the solar wind" and is exiting the solar system. This nice article explains what this means, and has a bunch of wonderful details and interviews with the original mission scientists. [more inside]
"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

"I can sense stars, and their whispers amid the roaring of our own Sun." So goes one poetic status of the Voyager 2 twitterfeed, which appeals to my sense of wonder like nothing else on the internet. Interstellar space probes and microblogging go hand in hand in the 21st Century.
A hot carbon-rich gas giant exoplanet, WASP-12b, has been discovered. As the lead author of the paper being published today, Nikku Madhusudhan, says: ""This planet reveals the astounding diversity of worlds out there". In particular, the discovery supports theories that there are likely to be planets made of diamond and graphite out there.
Built as part of the fifth /dev/fort developer retreat, Spacelog.org allows you to explore early space missions via the original NASA transcripts. Currently live are Mercury 6 which made John Glenn the first American in orbit, and the 'successful failure' Apollo 13 (The transcribed key moment and the original). Alongside the transcripts are supporting materials from the NASA archives including photography and descriptions of the mission phases. The developers are looking for help to digitise the Gemini 7, Apollo 8 and Apollo 11 missions.
Did you know that there's an art museum on the moon? A tiny, tiny one. The Moon Museum features works by Forrest "Frosty" Myers (the instigator), Robert Rauschenberg, Claes Oldenburg, Andy Warhol, David Novros, and John Chamberlain, inscribed on a little chip of silicon and surreptitiously transported to the moon's surface on the Apollo 12 mission. But of course there's a mystery, in this big of a secret: who is John F., the engineer at least partially responsible for smuggling the chip onboard the lunar lander? Related: other stuff people have left on the Moon (!)

One small step for a robot, one giant leap for robot-kind... but not yet. The Robonaut R2 (sic) will have to wait at least another three weeks, as the final mission of Space Shuttle Discovery is delayed.
“There’s a certain exuberance that comes from being out there on the edge of technology, where things are not certain, where there is some risk, and where you make something work.” Joseph Gavin Jr., an MIT-trained engineer and director of the Apollo 11 lunar module program for Grumman Aircraft Engineering Corporation, died on Saturday. A few quotes from Joe about the program's complexity via an old Popular Mechanics article are nice, but this more complete interview providing some fascinating insights on the process and the culture and just how much went into the lunar lander program, from an engineer's perspective, is fantastic.
We are nearing the end of a golden age of astronomy as more than a dozen space observatories reach their end of life in a few years. The only replacement on the horizon is the James Webb Space Telescope, scheduled to launch in 2014. Due to its enormous complexity and ever-rising costs, the JWST has starved other projects of funding. The fate of an entire generation of cosmologists and astrophysicists rests on its success.
Space Settlements collects various resources relating to the human colonisation of space: online books (including NASA studies from 1975, 1977 and 1992), a contest for schoolkids (so NASA can steal their ideas, natch), but most importantly, kitschy 70s pictures of proposed space colonies (toroidal, spherical, OR cylindrical!).

On July 17th, NASA's Wide-field Infrared Survey Explorer (WISE) satellite completed its first survey of the entire sky viewable from Earth. After just seven months in orbit, WISE -- a precursor to the planned James Webb Space Telescope -- has returned more than a million images that provide a close look at celestial objects ranging from distant galaxies to asteroids. The first release of WISE data, covering about 80 percent of the sky, will be delivered to the astronomical community in May of next year, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries (containing just a small selection of images): 1, 2, 3, 4.

Last year, high school science teacher Ron Dantowitz of Brookline, Mass., played a clever trick on three of his best students. He asked them to plan a hypothetical mission to fly onboard a NASA DC-8 aircraft and observe a spacecraft disintegrate as it came screaming into Earth's atmosphere. For 6 months, they worked hard on their assignment, never suspecting the surprise Dantowitz had in store. On March 12th, he stunned them with the news: "The mission is real, and you're going along for the ride."
Barring the need for STS-335 and any potential extension to the program, today's 2:30 EST scheduled launch of OV-104 Atlantis on STS-132 (pdf) will be her 32nd and final trip to space. She's had a good run (gratuitous launch vid).
