The Mars rover Opportunity is heading up hill.
Even after a decades, this rover is still functioning and doing real exploration. It is an incredible engineering achievement.
Boeing has finalized its lease for building its manned capsule in one section of the giant Vehicle Assembly Building at the Kennedy Space Center.
The first Cygnus capsule has been de-orbited, burning up in the atmosphere.
A 100% success. The U.S. now has two different ways to get cargo to low Earth orbit. Soon, if all goes as it should, we shall have multiple ways to put humans there as well.
In an engineering test, LADEE successfully used a laser to beam information back from the Moon this past weekend.
Lasers could enhance space communications and lead to radical changes in spacecraft design. Today’s spacecraft communicate with radio, but radiofrequency wavelengths are so long that they require large dishes to capture the signals. Laser wavelengths are 10,000 times shorter than radio, the upshot being that a spacecraft could deliver much more data then even the best modern radio system. For scale, NASA says that the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft that’s carrying this laser experiment would take 639 hours to download an average-length HD movie using ordinary S-band communications. LLCD could download the film in less than eight minutes.
The next Dragon flight has now been scheduled for no earlier than February 11.
The next flight of SpaceX’s Dragon has been realigned to a February 11, 2014 NET (No Earlier Than) launch date. The launch will mark Dragon’s first ride on the upgraded Falcon 9 v.1.1 rocket, potentially sporting landing legs, as Elon Musk plans his next attempt at proving the rocket’s ability to return its stages back to Earth for reuse.
SpaceX must first launch two commercial satellites with the upgraded Falcon 9 before its NASA flight. Also, 2014 will be a very business year for the rocket, as it is scheduled to send three cargo missions to ISS plus launch eight commercial satellites.
An engineer describes how he and four other engineers debugged a fully fueled Saturn 5 rocket while it was the launchpad.
The Saturn V was more noisy and ghostly than I had ever expected and it had grown much taller and certainly more threatening since last week. The venting fuel made loud hissing sounds when relief valves popped or opened up suddenly. It was very easy to let your imagination infect your brain. This is a very dangerous place and everything seems to be moving in the heavy foggy mist. There was no way to talk to each other, heck, we could barely see each other and…we hadn’t thought of this problem so we held onto each others yellow protective clothing like kindergartners crossing the street. We all wore safety helmets but they just did not make you feel like you were really safe.
This was also the first test launch of the Saturn 5, so the unknowns were significantly magnified.
The competition heats up: A new company is now offering balloon flights to the edge of space for one third the price of a suborbital flight.
World View passengers will soar to an altitude of about 30 kilometers (about 100,000 feet) — far short of SpaceShipTwo’s intended 110-kilometer (68-mile) high peak. Inside the capsule there will be little sensation of microgravity. Rather, the whole point of the ride is the view. “You can be sitting up there having your beverage of choice watching this extraordinary spectacle of the Earth below you and the blackness of space,” project co-founder and Paragon president Jane Poynter told Discovery News. “It really is very gentle. You can be up at altitude for hours, for days for research if you need to be… I think we have the opportunity to give a really, really incredible experience to people — and for a lot less than most of what’s out on the market right now,” she said.
Cygnus has undocked from ISS and will be de-orbited tomorrow.

The great Martian dust storm of 1971.
There has only been one comparable global dust storm on Mars since then. What made the 1971 even more significant historically is that the first human orbital probe had arrived at that very moment to record it.
By late 1971 and into January 1972 the storm abated, and Mariner 9 began to send back some spectacular images – a total of over 7,300 pictures that mapped the entire martian surface with resolutions ranging from 1 kilometer per pixel to as good at 100 meters per pixel.
The image here gives a sense of the magnitude of the storm. This was what the scientists began to see as the dust settled. The only visible features are the three great Tharsis Montes shield volcanoes, poking up through the haze in a line. The tallest of these reaches an altitude of over 18 kilometers. These peaks, and the enormous bulk of Olympus Mons had never been imaged by a spacecraft before, earlier flybys had missed them.
The late Bruce Murray (Caltech) was on the camera team and recalls, “there was a gradual clearing, like a stage scene, and three dark spots showed up.” The Mars that came out of the storm was a revelation, from these colossal mountains to the great rift of Valles Marineris and the steep valleys of Noctis Labyrinthus.
Want a rocket to launch your satellite into orbit. Orbital Sciences has one.
The article essentially outlines the marketing push Orbital is doing to get additional commercial contracts for its Antares rocket.
The image on the right is a cropped close-up of a Mars Reconnaissance Orbiter image taken in early September that shows a fresh cluster of impacts, all smaller than six feet across. Nearby but not visible in this image are four larger craters about 12 to 15 feet in diameter. The impact cluster is located just northwest of Gale Crater and was not present in images taken before Curiosity’s arrival on Mars. The cluster is also in line with other impact craters produced by other debris dropped by Curiosity as it descended onto the Martian surface.
Scientists are at the moment unsure what spacecraft debris caused these impacts.
Assigning each of the impacts to specific pieces of hardware is a challenging puzzle, but it is thought that the four large craters were produced by two large tungsten weights that broke in half to make these four craters, or by pieces of the cruise stage, which was designed to break up in the atmosphere for planetary protection purposes, to kill any Earthly microbes.
The cluster imaged here adds to the mystery, and may have been produced by a piece of the cruise stage that traveled farther through the Martian atmosphere and was therefore more thoroughly fragmented by the time it crashed onto the surface.
Identifying the source of the debris is a challenging engineering problem that also has scientific interest. Knowing what caused the impacts and then studying how the surface was changed by them will tell geologists a great deal about the make up of that surface.

A newly discovered half-mile wide asteroid has 1 in 63,000 chance of hitting the Earth in 2032.
That’s the Russian report above, which on these matters tend to be panic-stricken. Here’s the JPL version, which downplays the concern.
The Twitter comment of the day: “More people have applied to live on Mars than have signed up for Obamacare.”
I almost never look at Twitter comments, but this one was too good to pass up.
The next test flight of a version of SpaceX’s Grasshopper could occur in New Mexico in December.
The story says this test will be with Grasshopper, but I think that is a mistake. Unless SpaceX is using this name for all its vertical landing test vehicles, the company had said the test vehicle to fly in New Mexico would be a full scale Falcon 9 first stage, with nine Merlin engines, not one as has Grasshopper.
Cygnus will be de-orbited one day early, on October 23.
At the same time, preparations move forward for the second Cygnus flight in December, which will be the first operational flight. This quote is interesting:
Neither Orbital nor the Virginia Commercial Space Flight Authority got locked out of the Mid-Atlantic Regional Spaceport as a result of the shutdown, meaning that preparations for the tentative December launch continued while more than 95 percent of NASA’s roughly 18,000 civil servants were on furlough.
Suggests again how unessential a good percentage of NASA’s employees really are. They might be great engineers, but they are apparently wasting their talents at NASA doing unnecessary make-work.
The government shutdown has put flight testing of Dream Chaser on hold.
It appears that the decision to do these flight tests at Dryden is the problem. As a NASA facility, it has been shut down. If the flight tests had instead been arranged at a private facility, Dream Chaser could still be flying.
On October 7 SpaceX successfully flew and landed Grasshopper on its highest flight yet, 2440 feet.

The test pilots who have been flying SpaceShipTwo report on their work at a test pilot symposium.
Lots of interesting engineering details about the ship’s flight capabilities, including one near disaster that was saved by SpaceShipTwo’s robust design. No details, however, on the state of the ship’s engine, or when further test flights at higher and higher altitudes will be attempted.

The competition heats up: SpaceX has revised the schedule for its next three launches, pushing back two weeks so engineers can review issues with the Falcon 9 upper stage engine.
The debut launch of the upgraded Falcon 9 successfully deployed Canada’s Cassiope spacecraft into orbit on September 29. However, after safely deploying its payloads, the upper stage was then set to restart its Merlin VacD engine for a second burn related to SpaceX’s ambitions to create a fully reusable launch system. An anomaly with the restart held no mission impact, but the company’s CEO and chief designer, Elon Musk, did note they expected to implement corrective actions ahead of the next launch. “In the case of the upper stage relight, we initiated relight and the system encountered an anomaly and did not complete the relight. We believe understand what that issue is and should have it addressed in time for the next flight of Falcon 9,” he noted. “We essentially saw the engine initiate ignition. get up to about 400 psi and then it encountered a condition that it didn’t like. We have all of the data from the restart, so I am confident that we will be able to sort it out and address it before the next flight. We just have to iron out some slight differences of it operating in vacuum.”
I find Musk’s vague terminology about the engine issue to be interesting. I wonder if the “condition” the engine “didn’t like” was when the engine exploded, as some have suggested. (I personally am skeptical the engine exploded, however, as such a failure would probably require a much longer delay to deal with.)
Either way, the next few months should be a busy time for commercial space. Not only does SpaceX have two major commercial launches and a Dragon mission to ISS, Orbital Sciences has its next Cygnus cargo mission and Virgin Galactic claims it will be ready to fly SpaceShipTwo with passengers.

The competition heats up: Jeff Bezos reveals some details about the goals of his space company, Blue Origin.
Blue Origin is now working on its third version of the New Shepard, which is designed to take everyday people on suborbital journeys. Bezos said that he’s hopeful that this will be the last iteration, and he wants to see the next vehicle ready for commercial operation. “I’m very optimistic about that,” he said. Bezos didn’t give any specific timetables. However, he did say that Blue Origin’s orbital vehicle, designed to send astronauts to the International Space Station and elsewhere, will be tested by 2018. Eventually, the goal is to let anyone fly up into space safely at reasonable prices.
Not a lot of details, but previously we knew practically nothing. That the present ship is being designed for suborbital tourist flights makes it a direct competitor of Virgin Galactic and XCOR. And considering the problems that Virgin Galactic has with SpaceShipTwo, and that XCOR doesn’t have the big bucks of Bezos, Blue Origin might actually be in the lead in the race to put the first tourists in space.
Boom! A remotely operated Russian telescope, located in New Mexico, on Wednesday discovered a kilometer wide Near Earth asteroid.
The asteroid, believed to be the 704th largest with an orbit that comes relatively near Earth, does not pose a danger of crashing into our planet, said the head of the observatory that made the discovery. “It’s a big asteroid, but it poses no danger for us,” Leonid Elenin, who lives in the Moscow Region, told RIA Novosti on Friday.
Finding a new asteroid like this illustrates that there might be other such large objects out there undiscovered. Also cool is how the Russians discovered it, using equipment in the United States!

Bureaucracy in space: In a new book, astronaut Chris Hatfield describes how a bureaucratic tangle with the space doctor bureaucracy almost grounded him before his ISS expedition.
“The secrecy and paternalism really bothered me. They trusted me at the helm of the world’s space ship, but had been making decisions about my body as though I were a lab rat who didn’t merit consultation.” The “they” Hadfield refers to are members of the Multilateral Space Medicine Board (MSMB), a body of representatives from the U.S., Canada, Europe, Japan and Russia who judge the medical fitness of astronauts to go on missions. ….
The bureaucracy wanted Hatfield to undergo an emergency operation to make sure everything was okay. He refused,
triggering what Hadfield describes as a “Kafkaesque” journey through “a bureaucratic quagmire where logic and data simply didn’t count.” … “Internal politics and uninformed opinions were what mattered,” he says in the book. “Doctors who hadn’t ever performed a laparoscopic procedure were weighing in; people were making decisions about medical risks as though far greater risks to the space program itself were irrelevant.”
I find this interesting in that, of the astronauts I have interviewed over the years, I can’t remember any who had good words to say about the official government doctors they had to deal with, both in the U.S. and in Russia.
