Chris Brandrick on the first civilian recruitment drive for Martian colonization:
Just as NASA’s latest rover prepares to land on the surface of Mars, one Dutch company is looking to up the ante, with plans to send humans to the distant red planet. But before you sign up for travels to faraway lands, you may want to take note that the trip is a one-way deal, meaning you’ll never be able to return home to Earth.
Mars One, the ambitious company behind the planned mission, is hoping that a number of brave civilians will be willing to embark upon the mission to be the first to occupy the planet.
The company, founded by Bas Lansdorp, wants to send a number of humans to live on our neighboring planet indefinitely by 2023. The timeline for the mission will see Mars One send out a communications satellite in 2016, with a rover being sent in 2018 to find a suitable site for a settlement. Once the company finds a suitable location, it’ll send settlement units to Mars in 2020, which the existing rover will then set-up.
Once it gets the settlement established, Mars One hopes to send a small crew that would leave Earth in December of 2022, and arrive in April of 2023.
Visiting Mars would be fantastic, but I think I’ll wait until a return booking is possible.

In The Register, Phil Muncaster reports on what is rumoured to be the next stage of India’s space program:
Not to be outdone by China in the space race, India is set to flex its muscles on the world stage, planning a mission to Mars late next year.
K Radhakrishnan, Chairman of the Indian Space Research Organisation (ISRO), told reporters on Saturday that there will be a definitive announcement on the scientific research-based project by the government soon.
“A lot of studies have been done on the possible mission to Mars. We have come to the last phase of approvals,” he said, according to Times of India.
The proposed Mars mission will apparently be focussed on the Red Planet’s origins and evolution, its climate and geography and whether life can be sustained there.

What followed Echo 1 was a space race within a space race, this one determining whether government or industry would send up the first active non-military communications satellite. In 1961, NASA awarded a contract for such a satellite to the company RCA, but Pierce and Bell Labs were undeterred. According to Calvin Tomkins, Bell Labs spent US$50-million (at early-1960s rates) for research and development and devoted about 700 of its personnel to the project.
The baby that was born of it all was a sphere weighing 170 pounds (77 kilograms), called Telstar 1. Going by specifications collected by Bill Yenne, an authority on U.S. spacecraft, Telstar 1 received signals at 6,390 megacycles, re-transmitted them at 4,170, and boasted of 600 voice channels and one channel for television.
Perched atop a Thor-Delta booster — paid for by Bell Labs but launched by NASA — Telstar 1 ascended on July 10, 1962. It did not go far, parking itself in an elliptical orbit less than 2,000 miles (3,220 kilometers) away. Within hours, Bell Labs arranged what was previously impossible — transatlantic television. As described by T.A. Heppenheimer, the ensuing video exchange humorously followed national stereotypes. The United States sent France and the U.K. taped material heavy on patriotic themes, the French responded with footage of actor Yves Montand and other cultural figures, and the British muddled about for a few days before getting things straight.
Humour aside, the achievement left the world stunned. In just the month of the launching of Telstar 1, the New York Times ran almost 100 articles related to the satellite. Joe Meek’s Telstar composition stormed the pop charts later in the year, and that 1963 New Yorker profile of Pierce ran for 29 pages. Telstar 1 did not outlast some of this acclaim, as it ceased transmission in early 1963, but it had blazed a path. Today, anyone using satellite TV or radio is honouring that decades-old triumph of engineering.
Arthur C Clarke is often credited with inventing the idea of satellite communications, though in fact his contribution was to point out that three birds in geostationary orbit could provide global coverage. Geostationary orbit is more than 35,000km up, beyond the reach of radios in 1962, so Telstar’s orbit peaked at less than 6,000km up and dipped down to less than 1,000km during its two-and-a-half-hour circumnavigation.
That dip is also what caused Telstar’s downfall. Its repeated drops into the Van Allen radiation belt did allow the satellite to gather information about the belt (which was part of the plan) but the information it gathered was largely the havoc such radiation plays with electronic circuits. If Wikipedia is to be believed then US nuclear tests at the time had left the Van Allen particularly charged, but either way the satellite failed intermittently for a few months and finally stopped relaying signals entirely in February 1963. However, it remains in orbit to this day, faithfully tracked by the US government as required by international treaties.
Telstar was solar powered, with 3,600 solar cells feeding 19 nickel-cadmium batteries which received a 6GHz signal and retransmitted it with 2.25w of power at 4GHz. The electrics necessary were all suspended by shock-absorbent nylon cords in the middle of the spherical body, which had to spin at 180 rpm for stabilisation (gyroscopes perform the same function on modern satellites, but weren’t reliable enough back then).
A blog post at New Scientist compares the achievement of the Chinese space program, which just successfully placed three astronauts aboard the ISS and the highly mysterious X-37B spaceplane which just completed a 469-day mission:
China’s space agency took the plaudits for successfully docking its crewed Shenzhou-9 spacecraft with its orbiting lab Tiangong-1 today, but the feat was slightly overshadowed by the weekend landing of the US X-37B spaceplane, which after a record-breaking orbital flight of 469 days showed just how far China has to go to catch up with advanced spacefaring nations.
At around noon local time, the Beijing Aerospace Control Centre relayed live pictures of Shenzhou-9’s docking on state broadcaster China Central Television. The space capsule held off at a distance of 62 kilometres from Tiangong-1 before making its docking approach just before 2pm — and once the crew had manually locked on to the latter’s cruciform docking target it took only eight minutes to latch the spacecraft together safely.
[. . .]
This Boeing-built spaceplane, roughly one quarter the size of the space shuttle, is equally mysterious. It flies to orbit on a regular rocket and when there deploys a solar array that gives its sensors the power they need for extended missions. It also has enough propellant to fire thrusters that make small changes to its orbit in a bid to foil surveillance. The vehicle re-enters the atmosphere just like the shuttle but lands entirely autonomously, making it a space drone.
At no point has the USAF revealed the craft’s purpose: in addition to spacecraft surveillance, it could deploy a robot that repairs (or disables) satellites in orbit, say some, while at the darker end of the spectrum of possibilities — it was a DARPA project in its early days — it could carry a warhead, using its drone homing capability to provide surprise precision strike from orbit.
In Wired, Dave Mosher has a profile of a fascinating little group with a sky-high goal:
Co-founders von Bengtson, an aerospace scientist and former NASA contractor, and Madsen, an entrepreneur and aerospace engineer, have a lot to be proud of since they founded their non-profit space program four years ago. In June 2011, for example, Copenhagen Suborbital’s army of volunteers successfully built, launched and recovered a 31-foot-tall rocket — the largest “amateur” launcher ever built — with a crash-test dummy tucked inside.
That first prototype ended its flight two miles up, and the organization has yet to check off their ultimate goal: sending a person more than 60 miles above the Earth, a height widely considered the boundary of outer space. But now they are creating a bigger, better and badder space vehicle to get there.
“We have gone from having a crazy idea on a submarine to a smoothly run organization that builds rockets and spacecraft, and has experience with big launches,” said von Bengtson, who also blogs about the project for Wired at Rocket Shop. “It feels like we have become a part of a new era in space. I wouldn’t trade that for anything. Not for millions of dollars.”

Brid-Aine Parnell at The Register on today’s successful rendezvous with the ISS:
Elon Musk’s SpaceX has just made history with the first ever commercial cargoship to be captured by the International Space Station’s robotic arm.

Flying above northwestern Australia, flight engineer Don Pettit aboard the ISS reached out with the Canadarm and grabbed the Dragon at 9.56am EDT, 14.56 GMT.
Reg staff are not sure if astronauts are given cheesy lines to say at these big moments, but Pettit had a great one ready.
“Looks like we’ve got a dragon by the tail,” he announced to Mission Control Centre in Houston.
“Looks like this sim went really well, we’re ready to turn it around and do it for real,” he joked.
Lewis Page at The Register on the successful Dragon fly-by of the ISS:
It’s another moment of truth for upstart space startup SpaceX as once again the company attempts to do something that has only ever been accomplished to date by major government space agencies: docking one spacecraft to another in orbit and transferring cargo.
Having launched its new Dragon spacecraft on Tuesday — on only its second flight — SpaceX is now seeking to bring the ship to a docking with the International Space Station on Friday. Many boxes must be ticked before this can happen, however: but today the first was checked off as the Dragon made a close pass within 1.5 miles of the station, and ‘nauts aboard the orbiting outpost confirmed that their remote-control console was able to command the new ship. This was done by ordering the Dragon to illuminate its strobe lights as it flew by the Station.
In fact the station’s crew — the Dragon tests were handled by André Kuipers of the ESA and NASA’s Don Pettit — couldn’t see that the lights were on owing to bright sunlight illuminating the still quite distant Dragon. However telemetry confirmed that the capsule had received the radio command from the ISS and activated its lights, and viewers of NASA TV were treated to video of the Dragon as it gradually overhauled the station from beneath, passing above South Africa and the Indian Ocean as it did so.

History is just days away from being made as SpaceX’ Dragon cargoship finally blasted off successfully on its Falcon 9 rocket this morning on its way to a rendezvous with the International Space Station.
Elon Musk’s private space firm has had a number of setbacks with the latest test flight of the Dragon, delaying again and again to make sure the software that will put it within spitting distance of the ISS was working properly. And just when it seemed there was no stopping the takeoff last Saturday, the computer held the ship on the ground.
The engines were already firing when the computer “saw a parameter it didn’t like” and aborted the trip. SpaceX engineers later replaced a faulty pressure valve.
However this morning at 08:44 UK time (03:44 US Eastern) there were no problems and the Falcon 9 rocket lifted off on schedule to place the Dragon capsule into an orbit which will carry it to a rendezvous with the station on Friday if all goes to plan.
The first hurdle in the commercial company’s maiden berthing with the ISS has been jumped, with the Dragon out of Earth’s atmosphere, but there’s still a lot to prove before Houston will give the go to attempt a docking.
Comments Off on SpaceX Dragon launches successfully
Lewis Page at The Register on the scrubbed launch this morning:
The Falcon 9 rocket from private space company SpaceX, intended to launch this morning and send a Dragon capsule loaded with supplies to the International Space Station, has failed to take off. The rocket’s computer aborted the launch automatically at almost the final possible moment, when its engines had already ignited but the vehicle had not yet been released from the pad.
“The computer saw a parameter it didn’t like,” commented launch controllers after the abort, which saw the Falcon’s 9 main engines flare briefly into life as the countdown reached zero before cutting out again.
The rocket is not thought to have been damaged by the aborted launch, and controllers announced a provisional plan to check the craft, refuel it and make another launch attempt on Tuesday morning at 03:44 AM local time (08:44 UK time).

Just to add some icing to the SpaceX Dragon launch cake, the cargoship may be carrying a secret payload that nobody knows about.
The first ever commercial spacecraft to dock with the International Space Station, due to go up tomorrow, will already be carrying nonessential food, student science projects, clothes and other supplies for the ISS crew, but Elon Musk’s firm has also hinted there could be something else aboard.
On the last test flight of the Dragon, the craft carried a Top Secret cargo SpaceX refused to reveal to anyone until after mission, which turned out to be a lovely big wheel of cheese in an homage to the classic Monty Python sketch in the cheese shop.
On a slightly more serious level, Jonathan Amos has this report at the BBC News site:
Although billed as a demonstration, the mission has major significance because it marks a big change in the way the US wants to conduct its space operations.
Both SpaceX and another private firm, Orbital Sciences Corp, have been given billion-dollar contracts to keep the space station stocked with food and equipment. Orbital hopes to make its first visit to the manned outpost with its Antares/Cygnus system in the coming year.
Lift-off for the Falcon is timed for 04:55 EDT (08:55 GMT; 09:55 BST). It is going up from Cape Canaveral Air Force Station.
The ascent phase should last a little under 10 minutes, with the Dragon capsule being ejected just over 300km (185 miles) above the Earth.
The conical spaceship will then deploy its solar panels and check out its guidance and navigation systems before firing its thrusters to chase down the station.
A practice rendezvous is planned for Monday when Dragon will move to within 2.5km (1.5 miles) of the station.
If Nasa and SpaceX are satisfied that the vehicle is performing well, it will be commanded to fly up and over the outpost in preparation for close-in manoeuvres on Tuesday.

Brid-Aine Parnell at The Reg updates us on the SpaceX flight schedule:
The flight of the Falcon 9 has once more been rescheduled, with a new launch date of 19 May, as Elon Musk’s SpaceX decided to tweak the software one more time.
The first commercial craft to restock the International Space Station, a Dragon capsule strapped to a Falcon 9 rocket, has seen more than its fair share of push-backs for the test flight, but it will all pay off if the cargo ship can dock with the station.
SpaceX has already shown it can release and retrieve the Dragon, but getting it to motor alongside the fast-moving ISS and accurately berth with it is no mean feat and the firm has tested and retested the necessary software in the hopes it won’t end up with egg on its face.
[. . .]
Providing this test flight is successful, the Dragon will start to fulfil the contract for a minimum of 12 flights to resupply the ISS. Since the ship is reusable, it will be the only spacecraft capable of bringing cargo back with it as well. And, ultimately, SpaceX hopes that a version of the Dragon will be its first manned spaceship as well.

In his Forbes column, Tim Worstall spins a tale that is worthy of Dr. Evil or other movie bad guy multi-billionaires:
We’ve now had the announcement of the business plans of Planetary Resources. Enough to excite everyone who read Heinlein or Jerry Pournelle as a teenager. But the big problem is how might they actually turn a proft? To which the answer is manipulation of the futures markets.
[. . .]
So, imagine that they have reached one of the nickel iron asteroids, it is high in the platinum group metals, they can mine it and they can deliver those pgms to Earth. The moment everyone knows that there is some hundreds of tonnes of these metals on the way down the price will collapse. The answer? Sell the metals in advance, through the futures markets. Get today’s price for delivery in the future.
In fact, sell many more futures than the amount of metal which is to be delivered: go short. As an example, say platinum is $2,000 an ounce (not far off the real price, $62 million a tonne). Planetary Resources is going to deliver 100 tonnes. But instead of selling $6 billion’s worth of platinum for delivery in three months, sell 10 times as much: $60 billion’s worth*. When that 100 tonnes splashes down, in fact when the market knows that the 100 tonnes is likely to splash down, then the market price will fall. Substantially but for illustration we’ll say to $200 an ounce.
The company then delivers that 100 tonnes for which it is paid the $6 billion agreed on those futures deliveries. It still owes the market another 900 tonnes but it can now cover its short at $200 an ounce having sold the futures at $2,000 an ounce. Use the $6 billion that’s going to be incoming to do so and what do we have at the end?
The company has $60 billion incoming from having sold futures. It has delivered 100 tonnes at $6 billion and covered the short for that $6 billion. Net profit $54 billion minus the cost of the space program. Which is pretty good really.
But it gets better … and more Bond-villainous.

So the space shuttle Discovery has flown its last mission; it’s been towed over the nation’s capital like a bruised Chevy after a demolition derby before being deposited at the Udvar-Hazy air and space museum in northern Virginia.
Other space junkers — Atlantis and Endeavour — are being retired like Brett Favre in a pair of Crocs, too, bringing to end an underwhelming three decades of fruitless and tragic exploration of low-earth orbiting patterns.
Let’s face it: Once we beat the Russians to the moon, the national rocket grew limper than Liberace at a speculum convention. NASA has been dining out on a single 1969 hit longer than Zager and Evans.
The good news is that amateur hour is now over and the private space race has begun. Where two Cold War superpowers failed, let a thousand business plans bloom!
